Description

Technical Field

[0001] This utility model belongs to the field of machinery, and specifically relates to a silo filtration and anti-collapse gate discharge device. Background Technology

[0002] Coal bunkers in mines and coal preparation plants, especially coal mine bunkers, are typically 30-60 meters high and 20-35 meters in diameter, with a capacity of 9,000 to 50,000 tons. The materials inside these bunkers contain a large amount of water. Existing mining equipment, such as gate discharge devices, generally lacks water filtration capabilities. Excessive water accumulation in the bunkers frequently leads to tsunami-like collapses, where massive amounts of material surge out instantly, engulfing equipment, facilities, and personnel below and around the bunker, causing casualties. Furthermore, the high water content in the bunkers causes other problems, including difficulties in material transportation, inaccurate material weighing, the inability to filter and clean the water, and coal slurry flowing into the motors of transport equipment. The corrosion and damage to components such as motors, rollers, bearings, drive components, frames, and electrical control facilities have significantly increased maintenance and cleaning work, reduced equipment lifespan, and caused serious environmental pollution and water waste. Furthermore, water seepage corrodes motors, frequently causing them to burn out, posing a significant safety hazard. If water mixed with the material leaks into the power source, it can cause the transportation equipment to stop for repair or be scrapped, or even burn out the mine's electrical circuits and transformers. To address these problems, through long-term research, manufacturing, and further research and innovation, this utility model proposes a silo water-filtering anti-collapse silo gate discharge device. Utility Model Content

[0003] This utility model is achieved using the following technical solution:

[0004] A silo filtration and anti-collapse gate discharge device includes a gate frame, a discharge plate, a gate track, and a gate opening / closing drive. The discharge plate has a raised center and its two sides are located on the gate track of the gate frame. The gate opening / closing drive drives the discharge plate to reciprocate along the gate track to open or close. The raised center portion of the discharge plate faces the center of the silo opening, allowing material to fall onto the silo filtration and anti-collapse gate. On the discharge plate, the gate track or the filter anti-collapse gate discharge plate includes a drainage trough. The gate track and the drainage trough are separate or connected separately or are integrated. The drainage trough is located at the lower part or side of the filter anti-collapse gate discharge plate. The filter anti-collapse gate discharge plate allows water in the material to flow from high to low along the inclined surface of the filter anti-collapse gate discharge plate into the drainage trough. The drainage trough collects the inflowing water or directs the inflowing water into a water collection container or into a lower water channel.

[0005] The silo filtration anti-collapse gate discharge device includes a gate frame, a silo filtration anti-collapse gate discharge plate, gate track, and gate opening / closing drive. The silo filtration anti-collapse gate discharge plate has a raised center and includes an obtuse-angled anti-collapse gate plate with its top facing the silo opening at an obtuse angle. Gate tracks are located on both sides of the gate frame. These tracks can be either roller gate tracks or flat gate tracks. The rollers in the roller gate tracks have roller surfaces, with the front and rear roller surfaces forming a roller surface track. Track gates that fit against the gate track surfaces are located on both sides of the obtuse-angled anti-collapse gate plate. The track gates are mounted on either the roller surface track or the flat gate track. The track gates are connected to the gate opening / closing drive, which drives the track gates to activate the filtration anti-collapse gate. The silo gate discharge plate is driven by a gate opening and closing drive unit to reciprocate along the gate track to open or close the silo opening. The raised middle section of the discharge plate faces the center of the silo opening, allowing material to fall onto it. The obtuse-angled apex gate plate includes a triangular or polygonal cross-section gate plate. The gate frame is equipped with a baffle that cooperates with the obtuse-angled apex gate plate. The baffle is located on the upper side of the obtuse-angled apex gate plate, and a filtration gap is provided between the baffle and the gate plate. The baffle can be a track-mounted baffle, a front baffle, or a rear baffle. The track-mounted baffle is located on the upper part of the gate track and the track gate plate. The front baffle is located on the water-filtering silo gate discharge plate as it reciprocates towards the center. On the gate frame, when the discharge plate of the filter silo gate is closed, the front end of the discharge plate cooperates with the front baffle of the gate to form a material-blocking and water-filtering structure. The gate frame includes a left arm and a right arm. The rear baffle is located after the discharge plate closes the silo opening, at a position opposite to the left and right arms of the gate frame. The two ends of the rear baffle are connected to the left and right arms of the gate frame, respectively, and supported by the gate frame. When the discharge plate is closed, the rear of the discharge plate cooperates with the rear baffle to form a material-blocking and water-filtering structure. The gate track includes a left gate track and a right gate track. The baffles on the track include either the baffle on the left track or the baffle on the right track. The material stoppers are located on the left and right tracks, respectively, and are positioned above the left gate track. They prevent material flow, causing water in the coal bunker to flow out along the obtuse-angled anti-collision gate, separating the coal and water in the bunker. The filtered water flows out of the bunker opening. The gate track, the water-filtering anti-collision gate discharge plate, or the gate frame includes a collection trough. This collection trough includes a lower collection trough below the material stopper or a collection trough along the gate track. The lower collection trough below the material stopper collects the filtered water, while the gate track collection trough is located at the gate track and supported by the gate frame. The gate track collection trough collects the water filtered by the upper water-filtering anti-collision gate discharge plate in conjunction with the material stopper. The gate track and the collection trough can be separate, separately connected, or integrated.The drainage trough is located at the lower or side of the discharge plate of the filter-resistant gate, or at the lower or side of the gate frame, or at the lower or side of the gate track. The discharge plate of the filter-resistant gate allows water in the material to flow from a high point to a low point along its inclined surface into the drainage trough. The drainage trough collects the inflowing water, or directs it into a collection container or into a lower water channel.

[0006] The obtuse-angle top anti-collision gate includes an obtuse-angle welded anti-collision gate or an obtuse-angle stamped anti-collision gate. The obtuse-angle welded anti-collision gate is made of two or more flat plates welded together. The two flat plates are aligned and positioned according to the height allowed by the site space to filter water. The two or more flat plates are then welded together to form an obtuse-angle welded anti-collision gate that filters and dries coal slurry water in the coal bunker. The obtuse-angle welded anti-collision gate has track gates on both sides that fit with the gate track. The obtuse-angle stamped anti-collision gate is made of a single flat plate. A bending machine is used to bend the middle of the flat plate into an obtuse-angle stamped anti-collision gate with a water-filtering angle. Then, the two sides of the obtuse-angle stamped anti-collision gate are stamped into track gates that are parallel and fit with the gate track. This allows the track gates to fit against the gate track and reciprocate to quickly close the hopper opening.

[0007] The baffle is fixed to the upper part of the gate frame. A water-filtering gap is provided between the baffle and the discharge plate of the water-filtering anti-collision gate, or the baffle is equipped with a water-filtering baffle. The baffle and the discharge plate work together to prevent material from flowing into the drainage trough, ensuring that water in the coal bunker can be quickly filtered and discharged from the bunker opening. The water-filtering baffle includes a mesh type, a perforated type, a trough type, a planar type, or an inclined type. A drainage trough is provided below or on the side of the baffle. The discharge plate of the water-filtering anti-collision gate also includes a plate-type anti-collision gate discharge plate or a plate-reinforced anti-collision gate discharge plate. The plate-reinforced anti-collision gate discharge plate passes through the bottom... The reinforcing ribs improve the load-bearing capacity of the reinforcing rib gate discharge plate, ensuring that the water distribution and filtration angles of the gate discharge plate do not deform, and improving the service life of the gate discharge plate. The collection and drainage trough includes a flow-guiding type collection and drainage trough, a filtration type collection and drainage trough, or a sludge-dredging type collection and drainage trough. The flow-guiding type collection and drainage trough directly guides the collected coal slurry water into the lower waterway or into the water collection container. The filtration type collection and drainage trough is equipped with a water collection trough filtration structure. The water collection trough filtration structure filters or purifies the coal slurry water collected in the collection and drainage trough and then guides the water into the waterway or into the water collection container. The water collection trough filtration structure includes a water collection trough hole type filtration structure, a water collection trough mesh type filtration structure, or a water collection trough type filtration structure.

[0008] The discharge plate of the water filter anti-collapse silt gate is equipped with an automatic sludge removal structure, which is located at one or both ends of the discharge plate. The automatic sludge removal structure includes L-shaped or C-shaped sludge removal components. The upper end of the L-shaped or C-shaped sludge removal components is fixedly or movably connected to the discharge plate of the water filter anti-collapse silt gate. The L-shaped or C-shaped sludge removal components are in contact with the drainage trough. The gate frame is equipped with gate plate support rollers or gate plate slides, which are supported by the gate frame. The gate plate support rollers or gate plate slides are in clearance fit with the drainage trough. The L-shaped or C-shaped sludge removal components are located between the gate plate support rollers or gate plate slides and the drainage trough. The L-shaped or C-shaped sludge removal components are in clearance fit with the gate plate support rollers or gate plate slides. When the discharge plate of the water filter anti-collapse silt gate reciprocates, it drives the L-shaped or C-shaped sludge removal components to push and scrape the accumulated mud and water in the drainage trough at the gate track. The drainage trough is equipped with mud and water discharge structures at both ends or on the sides. The mud and water discharge structures include water filter pipes or mud and water discharge troughs. The water filter pipes or mud and water discharge troughs are set at the ends or sides of the drainage trough. One end is fixedly connected to the wall of the drainage trough, and the other end is set downwards to facilitate the discharge of mud and water without clogging.

[0009] The gate frame and the front end of the filter gate discharge plate are equipped with sealing elements. These sealing elements are located at the upper or lower part of the joint between the gate frame and the front end of the filter gate discharge plate. When the filter gate discharge plate is closed, the sealing elements seal the gap between the gate frame and the front end of the filter gate discharge plate, preventing mud and water from flowing out. This allows water in the material to be filtered out by the filter gate discharge plate and flow into the collection and drainage trough. The rear ends of the filter gate discharge plate and the collection and drainage trough are equipped with an automatic closing sealing structure, which includes a rear end seal for the filter gate plate or a rear end seal for the collection and drainage trough. When the filter gate discharge plate is equipped with a rear end seal... When the filter gate is closed, a leak-proof component is installed at the rear end of the drainage trough to cooperate with the rear end seal of the filter gate. When the gate opening and closing drive drives the filter gate discharge plate to release material, the rear end seal of the filter gate and the leak-proof component at the rear end of the drainage trough close to prevent mud and water from flowing out from the rear of the drainage trough. When the gate opening and closing drive drives the filter gate discharge plate to release material, the rear end seal of the filter gate and the leak-proof component at the rear end of the drainage trough are automatically opened. The automatic sludge removal structure at the front end of the filter gate discharge plate scrapes the mud and water in the drainage trough backward and automatically falls into the feeder, where it is transported out with the material. This collects and utilizes the material and protects the various components of the conveyor and the electrical control system from corrosion and damage.

[0010] A sludge sedimentation tank is located at the rear of the drainage trough inside the gate frame. The sedimentation tank includes a guide pipe and a sedimentation tank. The guide pipe can be either a through-hole type or a filter type. The filter type guide pipe includes a filter structure, which is located at the junction of the guide pipe and the sedimentation tank arm. The sedimentation tank collects the sludge filtered by the discharge plate of the filtration gate. The guide pipe discharges the water collected in the sedimentation tank. The sedimentation tank allows the sludge in the sludge to settle. The bottom of the sedimentation tank is level with or lower than the bottom of the drainage trough. The sludge in the drainage trough flows to the sedimentation tank by itself, or an automatic sludge removal mechanism scrapes the sludge from the drainage trough and directs it into the sedimentation tank. An automatic sludge remover is located at the rear end of the discharge plate of the filtration gate. The automatic sludge remover is activated when the gate is closed. The gate is located at the front of the sedimentation tank. A sludge discharge gap is provided between the automatic sedimentation tank sludge remover and the drainage trough. The coal sludge water filtered by the filter gate's discharge plate flows into the sedimentation tank through this gap. As the filter gate's discharge plate moves backward when the discharge is initiated, the automatic sedimentation tank sludge remover automatically adheres to the sedimentation tank wall, scraping the sludge out of the sedimentation tank into the sedimentation tank. The rear of the sedimentation tank is equipped with a spring-sealed door or a magnetic rotating door. The spring-sealed door includes a spring door panel and a telescopic door spring. The rear end of the telescopic door spring is mounted on the gate frame. An elastic door panel is located at the end of the telescopic door spring facing the sedimentation tank. The telescopic door spring pushes the elastic door panel to seal and prevent leakage at the rear of the sedimentation tank. The elastic door panel can be a flat elastic door panel or a sealing elastic door panel. The door panel is equipped with door panel seals around its perimeter. The spring-loaded telescopic door panel pushes against these seals to prevent water leakage from the sedimentation tank. The spring-loaded door directly pushes against the rear end of the sedimentation tank, sealing it. Alternatively, the spring-loaded door can be installed within the sedimentation tank channel. When the spring-loaded door is installed within the sedimentation tank channel, the sedimentation tank has a rear material leakage structure at the rear of the elastic door panel. This rear material leakage structure includes a left rear material leakage wall, a right rear material leakage wall, and a rear material leakage outlet. The opening and closing angles of the rear material leakage outlet, left rear material leakage wall, and right rear material leakage wall are the same. Alternatively, the left rear material leakage wall and right rear material leakage wall face the rear material leakage outlet and have a left and right supporting elastic door panel platform, respectively. When the elastic door panel is pushed to the rear material leakage structure, the left supporting elastic door panel... The platform and right-hand elastic gate ensure the elastic gate moves back and forth within the sedimentation tank channel. The elastic gate accurately seals the rear of the sedimentation tank or allows the scraped sediment to enter the discharge port behind the gate, flowing into the feeder and being transported out with the material. The elastic gate is equipped with a gate sealing element around its perimeter, the area of ​​which is larger than the cross-sectional area of ​​the sedimentation tank channel, ensuring a tight seal. The rear end of the filter anti-collapse gate discharge plate is equipped with an opening spring sealing door mechanism or an opening magnetic door mechanism. When the gate opening and closing drive drives the filter anti-collapse gate discharge plate backward, the spring sealing door mechanism opens, causing the telescopic gate spring to retract. Simultaneously, it pushes the sludge from the sedimentation tank to the discharge structure behind the gate. The sludge in the sedimentation tank is scraped and pushed through the discharge port behind the gate, falling into the feeder.The magnetic rotating door is installed at the rear end of the sludge sedimentation tank, transported along with the materials. A rotating shaft is located at the upper rear end of the sedimentation tank, and the magnetic rotating door has a rotating door sleeve that mates with the rotating shaft. The rotating door sleeve passes through the rotating shaft. An adsorption magnet is located at the rear end of either the magnetic rotating door or the sedimentation tank. The magnetic rotating door adheres to the rear end of the sedimentation tank, sealing it. When the gate opening and closing drive mechanism drives the filter anti-collapse gate discharge plate to retract, the magnetic door mechanism opens, pushing the magnetic rotating door open and simultaneously pushing the sludge in the sedimentation tank onto the feeder conveyor belt.

[0011] The silo filtration and anti-collapse silo gate discharge device includes a silo pressure measuring mechanism, which includes a pressure sensor and a pressure display, or a material level detector. The gate frame is equipped with a support for the pressure sensor, which is positioned above it. The gate track includes a silo pressure measuring gate track, which is detached from the gate frame and supported by the pressure sensor. The silo filtration and anti-collapse silo gate discharge plate is positioned on the silo pressure measuring gate track. When material falls onto the silo filtration and anti-collapse silo gate discharge plate, the pressure sensor senses the pressure on the discharge plate, and the pressure display shows the silo pressure value. The pressure sensor directly detects the silo pressure, or it works in conjunction with the material level detector to detect the pressure of the material inside the silo. When the pressure sensor works with the material level detector to detect the pressure of the material inside the silo, the silo pressure measuring mechanism... The system includes a material weight calculator, a material level detector to measure the height of the material in the silo, a material weight calculator to calculate the volume of the material in the silo, and a material weight multiplied by the material density to calculate the weight of the material in the silo. The volumetric weight of the material corresponding to the silo opening is relatively stable, meaning that the weight of the material measured by the silo pressure sensor should theoretically be the volume of the material multiplied by the material density. If the weight measured by the pressure sensor is higher than the volume of the material multiplied by the material density, it indicates that there is moisture in the gaps between the materials in the silo. The larger the weight difference, the higher the moisture content of the material in the silo, indicating that the risk of silo collapse needs to be eliminated in time. If the weight measured by the pressure sensor is lower than the volume of the material multiplied by the material density, it indicates that the material is stuck or clinging to the walls of the silo and cannot flow to the silo discharge port, indicating that the problem of sticking or clinging needs to be addressed in time.

[0012] The silo pressure monitoring mechanism includes a silo pressure alarm. When the weight measured by the pressure sensor is higher than the allowable value of the corresponding material volume multiplied by the material density, it indicates that the moisture content of the material in the silo exceeds the standard, which may easily cause a silo collapse. The silo pressure alarm will sound, prompting urgent anti-collapse measures to be taken. When the weight measured by the pressure sensor is lower than the allowable value of the corresponding material volume multiplied by the material density, it indicates that the material is stuck or clinging to the walls of the silo, and the material cannot flow to the silo discharge port. The silo pressure alarm will sound, prompting that the stuck or clinging problem needs to be dealt with in a timely manner. The silo pressure alarm uses audible and visual alarms to prompt immediate action to address the potential silo collapse hazard. It automatically discharges the potential silo collapse hazard through signal transmission. It also automatically controls the opening of the filter gate's discharge plate to a certain extent to guide the coal slurry water, allowing the coal slurry water to flow out gradually and in an appropriate amount, preventing the coal slurry water from gushing out when the gate is fully opened, which could cause a silo collapse. When stuck or clinging occurs, the silo pressure alarm prompts that the stuck or clinging problem must be dealt with in a timely manner to ensure efficient and safe production of coal storage and transportation.

[0013] A material moisture detector is provided as part of a silo filtration and anti-collapse gate discharge device. The material moisture detector is disposed within a perforated filtration structure, a drainage trough, or between a baffle and the discharge plate of the silo filtration and anti-collapse gate. When the material moisture detector is disposed within a perforated filtration structure, the perforated filtration structure includes filtration holes, and the material moisture detector is disposed on the side or bottom of the filtration holes. When the material moisture detector is disposed within a drainage trough, the drainage trough includes a moisture detector slot or a side wall of the drainage trough, and the material moisture detector is disposed within the moisture detector slot or on the side wall of the drainage trough. When the material moisture detector is disposed between the baffle and the discharge plate of the silo filtration and anti-collapse gate, the material moisture detector is disposed below the baffle and above the discharge plate of the silo filtration and anti-collapse gate.

[0014] Material moisture detectors include digital display material moisture detectors and alarm material moisture detectors. Digital display material moisture detectors include a moisture detector and a moisture fraction display. The moisture detector detects water flow velocity, water level, or material moisture content, while the moisture fraction display shows the water flow velocity, water level, or material moisture content. Alarm material moisture detectors include a moisture detector and a moisture alarm. The moisture alarm and silo pressure alarm are either separate or integrated. The moisture detector detects water flow velocity, water level, or material moisture content, and displays the water flow velocity, water level, or material moisture content. If the material humidity is abnormal, the moisture alarm will sound, indicating that excessive moisture in the silo could easily cause a silo collapse, requiring immediate action to control the moisture and prevent collapse. Alternatively, it may indicate that the material is sticking to the walls or bulging, requiring immediate action to control the material's sticking or bulging. Timely detection and alarm will promptly alert personnel or the control system to eliminate potential safety hazards.

[0015] 1. The discharge plate of the water-filtering anti-collision silo gate is raised in the middle, with gate rails on both sides set on the gate frame. The gate opening and closing drive drives the discharge plate, which reciprocates along the gate rails to open or close. The raised part of the discharge plate faces the center of the silo opening, allowing material to fall onto it. A drainage trough is located below or on the side of the discharge plate. The discharge plate causes water in the material to flow down the inclined surface of the discharge plate into the drainage trough. The drainage trough collects the water, directs it into a collection container, or directs it into a lower water channel, effectively preventing silo collapse caused by excessive water accumulation and the sudden spraying of large amounts of material. The outflow caused instantaneous damage to equipment, facilities, and personnel in and around the silo, preventing accidents such as casualties. It also prevented difficulties in material transportation and inaccurate material weighing due to the large amount of water in the silo, and prevented the water from being filtered out and cleaned. It prevented coal slurry water from flowing into the rollers, bearings, drive components, and frames of the transport equipment, preventing rust and damage to the rollers, bearings, drive components, and frames under the gate, avoiding a large amount of maintenance and cleaning work, and extending the service life of the equipment. It also prevented serious environmental pollution and water waste, prevented motor burnout caused by water erosion, prevented the transport equipment from being shut down or scrapped due to water mixed in with the material leaking into the power supply, and prevented the burning out of mine circuits and transformers.

[0016] The obtuse-angled top anti-collision gate has its top angled upwards towards the hopper opening. The gate track includes a roller gate track or a flat gate track. The rollers of the roller gate track include roller surfaces, and the front and rear roller surfaces form a roller surface track. The obtuse-angled top anti-collision gate has track gates on both sides that fit against the gate track surface. The track gates are set on the roller surface track or the flat gate track. The track gates are connected to the gate opening and closing drive mechanism. The gate opening and closing drive mechanism drives the track gates, which in turn drives the filter anti-collision gate discharge plate. The filter anti-collision gate discharge plate reciprocates along the gate track to open or close the hopper opening. The obtuse-angled top anti-collision gate includes a triangular cross-section filter gate or a polygonal cross-section filter gate. The gate frame is equipped with a matching mechanism. The combined baffle is located on the upper side of the obtuse-angled anti-collision gate plate. A water-filtering gap is provided between the baffle and the obtuse-angled anti-collision gate plate. The baffle prevents the material flow, causing the water in the coal bunker to flow out along the obtuse-angled anti-collision gate plate, thus separating the coal and water in the bunker and allowing the filtered water to flow out of the bunker opening. The collection and drainage trough is located at the lower or side of the discharge plate of the water-filtering anti-collision gate, or at the lower or side of the gate frame, or at the lower or side of the gate track. The discharge plate of the water-filtering anti-collision gate causes the water in the material to flow from high to low along the inclined surface of the discharge plate into the collection and drainage trough. The collection and drainage trough collects the inflowing water or directs the inflowing water into a water collection container or into a lower water channel. The obtuse-angled anti-collapse gate is superior to the old-style arc-shaped water diversion gate in that the obtuse angled apex faces the center of the coal bunker's discharge port, allowing water to flow straight from the top into the collection and drainage trough. This ensures the filtered water flows out of the bunker quickly and directly over the shortest distance. It eliminates the space occupied by the arc-shaped bulge of the arc-shaped water diversion gate, replacing the arc with a straight line. This eliminates the arc-shaped structure that would otherwise obstruct the rapid flow of filtered water, increasing the outlet angle of the filtered water and shortening the distance it travels out of the bunker. This maximizes the angle, speed, and volume of water that could cause a collapse within the bunker, allowing it to flow into the collection and drainage trough at the maximum allowable height of the gate, further effectively preventing the problems described above.

[0017] 2. The obtuse-angle welded anti-collision gate is made of two or more flat plates welded together. The two plates are butt-jointed and positioned at the allowable height according to the site space to achieve a filtering angle. Then, the two or more plates are welded together to form an obtuse-angle welded anti-collision gate that filters and drains coal slurry water from the coal bunker. The obtuse-angle welded anti-collision gate has track gates on both sides that fit with the gate's track. The obtuse-angle stamped anti-collision gate is made from a single flat plate. A bending machine is used to bend the middle of the flat plate into an obtuse-angle stamped anti-collision gate with a filtering angle. Then, the two sides of the obtuse-angle stamped anti-collision gate are stamped into track gates parallel to and fitted with the gate's track. This allows the track gates to reciprocate and quickly close the silo opening. The obtuse-angle welded anti-collision gate can utilize existing steel plates to manufacture anti-collision gates for silo openings of approximately 2 meters square. Existing steel plates are butt-jointed and welded together to form the anti-collision gate panel, saving materials and speeding up production. This design is fast and simple. The obtuse-angle stamped anti-collision gate is made from a single steel plate, eliminating the need for high-temperature heating followed by stamping into an arc shape using a large-radius mold. This avoids the deformation problem of the arc-shaped water diversion gate due to thermal expansion and contraction after high-temperature heating. It also avoids the large deformation of the arc-shaped water diversion gate when used in a 2-meter square silo opening, which would cause the track gate plates on both sides of the deformed arc-shaped water diversion gate to deform and fit tightly against the gate track, increasing running resistance and causing damage to the track and gate due to the deformed track gate plates only partially fitting against the gate track. This solution simplifies the manufacturing process of the obtuse-angle welded and stamped anti-collision gates, saving manpower, materials, and time. It avoids the environmental pollution and energy consumption caused by the heat treatment required for arc-shaped gate plates, and improves the manufacturing accuracy and efficiency of the obtuse-angle welded and stamped anti-collision gates.

[0018] 3. The baffle is fixed to the upper part of the gate frame. A water-filtering gap is provided between the baffle and the discharge plate of the water-filtering anti-collision gate, or the baffle is equipped with a water-filtering baffle. The baffle and the discharge plate work together to prevent material from flowing into the drainage trough, ensuring that water in the coal bunker can be quickly filtered and discharged from the bunker opening. The water-filtering baffle includes a mesh type, a perforated type, a trough type, a flat type, or an inclined type. The water filter on the baffle prevents material from flowing into the drainage trough while increasing the filtration and discharge volume of water accumulated at the bunker opening. A drainage trough is provided below or to the side of the baffle. The discharge plate of the water-filtering anti-collision gate also includes a plate type or a plate-reinforced anti-collision gate discharge plate. The plate-reinforced anti-collision gate discharge plate improves the load-bearing capacity of the reinforcing gate discharge plate through the bottom reinforcing ribs, ensuring... The water distribution and filtration angles of the gate discharge plate remain unchanged, improving its service life. The collection and drainage troughs include flow-guiding, filtration, and sludge-clearing types. Flow-guiding troughs directly guide the collected coal slurry water into the lower waterway or into a collection container. Filtration troughs have a filtration structure that filters or purifies the collected coal slurry water before guiding it into the waterway or collection container. The filtration structure includes perforated, mesh, or trough-type structures. These various types of collection and drainage troughs optimize their function, especially by increasing the collection of large amounts of filtered water through multi-directional placement, preventing the overflow of water filtered from the obtuse-angled anti-collapse gate plate and its potential to pollute the environment, equipment, and facilities.

[0019] 4. An automatic sludge removal structure is installed at one or both ends of the discharge plate of the filter anti-collapse gate. The automatic sludge removal structure includes L-shaped or C-shaped sludge removal components. The upper end of the L-shaped or C-shaped sludge removal component is fixedly or movably connected to the discharge plate of the filter anti-collapse gate. The L-shaped or C-shaped sludge removal component fits snugly against the drainage trough. The gate frame is equipped with gate plate support rollers or gate plate slides, which are supported by the gate frame. The gate plate support rollers or gate plate slides are fitted with the drainage trough with a clearance. The L-shaped or C-shaped sludge removal component is positioned between the gate plate support rollers or gate plate slides and the drainage trough. During operation, the L-shaped or C-shaped sludge-clearing components are fitted with the gate rollers or gate slide rails with clearance. When the discharge plate of the filter-type anti-collision gate reciprocates, it drives the L-shaped or C-shaped sludge-clearing components to repeatedly push and scrape away the accumulated mud and water in the collection and drainage trough at the gate track. This timely collection of mud and water in the collection and drainage trough effectively prevents blockage and sludge buildup that could hinder the gate rollers' rotation. This ensures that the mud and water filtered by the discharge plate of the filter-type anti-collision gate are promptly cleared, guaranteeing good fit between the gate track and the discharge plate, and ensuring long-term stable filtration and drainage of the coal bunker anti-collision gate. The collection and drainage trough is equipped with mud and water discharge structures at both ends or sides. A water guide pipe or mud and water discharge trough is located at the end or side of the collection and drainage trough, with one end fixedly connected to the trough wall and the other end angled downwards. This facilitates mud and water discharge without blockage, ensuring timely drainage and treatment of the discharged mud and water.

[0020] 5. The sealing element is installed at the upper or lower part of the joint between the gate frame and the front end of the filter anti-collapse silo gate discharge plate. When the filter anti-collapse silo gate discharge plate is closed, the sealing element seals the gap between the gate frame and the front end of the filter anti-collapse silo gate discharge plate, preventing mud and water from flowing out from the gap. This allows the water in the material to be filtered out by the filter anti-collapse silo gate discharge plate and flow into the collection and drainage trough. The automatic closing sealing structure includes a rear end seal of the filter gate plate or a rear end seal of the collection and drainage trough. When the filter anti-collapse silo gate discharge plate is equipped with a rear end seal, the rear end of the collection and drainage trough is equipped with a seal that matches the rear end seal of the filter gate plate. When the gate opening and closing drive mechanism drives the filter anti-collision silt gate discharge plate to release material, the rear sealing component of the filter gate and the rear leakage blocking component of the drainage trough close to prevent mud and water from flowing out from the rear of the drainage trough. When the gate opening and closing drive mechanism drives the filter anti-collision silt gate discharge plate to release material, the rear sealing component of the filter gate and the rear leakage blocking component of the drainage trough are automatically opened. The automatic sludge removal structure at the front of the filter anti-collision silt gate discharge plate scrapes the mud and water in the drainage trough backward and automatically falls into the feeder, where it is transported out with the material. This process collects and utilizes the material and protects the various components of the conveyor and the electrical control system from corrosion and damage.

[0021] 6. The sludge sedimentation tank collects the sludge filtered by the discharge plate of the filter gate. A water pipe leads the collected water out of the sedimentation tank. The sedimentation tank allows the sludge in the sludge to settle. The bottom of the sedimentation tank is level with or lower than the bottom of the collection trough. The sludge in the collection trough flows to the sedimentation tank by itself, or an automatic sludge removal mechanism scrapes the sludge from the collection trough and directs it into the sedimentation tank. An automatic sludge remover is located at the rear of the discharge plate of the filter gate. When the gate is closed, the automatic sludge remover is positioned in front of the sedimentation tank. A sludge discharge gap is provided between the automatic sludge remover and the collection trough. The coal sludge filtered by the discharge plate flows into the sedimentation tank through this gap. The sludge remover is activated when the discharge is opened. When the anti-collapse gate's discharge plate moves backward, it automatically adheres to the sedimentation tank wall, scraping the sludge out of the sedimentation tank into the sludge sedimentation tank. The rear end of the sedimentation tank is equipped with a spring-loaded sealing door or a magnetic rotating door. The spring-loaded sealing door includes a spring door plate and a telescopic door plate spring. The rear end of the telescopic door plate spring is mounted on the gate frame. An elastic door plate is located at the end of the telescopic door plate spring facing the sedimentation tank. The telescopic door plate spring pushes the elastic door plate to seal and prevent leakage at the rear end of the sedimentation tank. Elastic door plate seals are located around the elastic door plate seal. The telescopic door plate spring pushes against the elastic door plate seals to prevent water leakage from the sedimentation tank. The spring-loaded sealing door can directly push against the rear end of the sludge sedimentation tank to seal it, or the spring-loaded sealing door can be installed inside the sludge sedimentation tank channel. When the spring-loaded sealing door is installed inside the sludge sedimentation tank channel, the sludge... The sedimentation tank has a rear material leakage structure at the rear of the elastic gate panel. This structure includes a left rear leakage wall, a right rear leakage wall, and a rear leakage outlet. The opening and closing angle of the rear leakage outlet is the same as that of the left and right rear leakage walls. Alternatively, the left and right rear leakage walls have left and right support platforms facing the rear leakage outlet. When the elastic gate panel is pushed to the rear material leakage structure, the left and right support platforms ensure the elastic gate panel reciprocates back and forth within the sedimentation tank channel. The elastic gate panel accurately seals the rear of the sedimentation tank or allows the scraped sediment to enter the rear leakage outlet, flowing into the feeder and being transported out with the material. Gate panel sealing elements are provided around the perimeter of the elastic gate panel. The sealing area of ​​the plate seal is larger than the cross-sectional area of ​​the sludge sedimentation tank channel, sealing the sludge sedimentation tank channel. The rear end of the filter anti-collapse gate discharge plate is equipped with an opening spring sealing door mechanism or an opening magnetic suction door mechanism. When the gate opening and closing drive drives the filter anti-collapse gate discharge plate to retract, the opening spring sealing door mechanism causes the telescopic door plate spring to retract, simultaneously pushing the sludge in the sedimentation tank from inside the sedimentation tank to the material leakage structure at the rear of the door plate. The sludge in the sedimentation tank is scraped and pushed through the door plate, falling into the feeder and being transported out with the material. The magnetic suction rotating door is located at the rear end of the sludge sedimentation tank. A rotating shaft is located at the upper rear end of the sludge sedimentation tank. The magnetic suction rotating door is equipped with a rotating door bushing that cooperates with the rotating shaft. The rotating door bushing passes through the rotating shaft. The magnetic suction rotating door or the rear end of the sludge sedimentation tank is equipped with an adsorption magnet.The magnetic rotating door adheres to the rear end of the sludge sedimentation tank, sealing it. When the gate's opening and closing drive mechanism moves the filter anti-collapse gate's discharge plate backward, the magnetic door mechanism opens, pushing the magnetic rotating door open and simultaneously scraping the sludge from the sedimentation tank onto the feeder conveyor belt. This invention further collects and settles the sludge in the drainage trough within the sludge sedimentation tank. The reciprocating motion of the filter anti-collapse gate's discharge plate enables unattended, automatic cleaning of the sludge in the drainage trough and sedimentation tank, further separating, storing, and reusing the coal sludge, reducing environmental pollution, improving water resource utilization, increasing material utilization, avoiding material waste, and enhancing on-site environmental protection.

[0022] 7. The gate frame is equipped with a support pressure sensor. The pressure sensor is located on top of the support pressure sensor. The pressure measuring gate track is detached from the gate frame and supported by the pressure sensor. The filter anti-collapse silo gate discharge plate is set on the pressure measuring gate track. When material falls onto the filter anti-collapse silo gate discharge plate, the pressure sensor senses the pressure on the discharge plate, and the pressure display shows the silo pressure value. The pressure sensor directly detects the silo pressure, or the pressure sensor works in conjunction with a level detector to detect the pressure of the material in the silo. When the pressure sensor works in conjunction with the level detector to detect the pressure of the material in the silo, the silo pressure measuring mechanism includes a material weight calculator. The level detector detects the height of the material in the silo, the material weight calculator calculates the volume of the material in the silo, and the volume of the material in the silo is multiplied by the material density to calculate the weight of the material in the silo. The volume and weight of the material corresponding to the silo opening are relatively stable, i.e., the silo pressure is measured. Theoretically, the weight of a material should be the volume of that material multiplied by its density. If the weight measured by the pressure sensor is higher than the volume of the material multiplied by its density, it indicates that there is moisture in the gaps between the materials in the silo. The greater the weight difference, the higher the moisture content of the material in the silo. This indicates that the risk of silo collapse needs to be eliminated in time to avoid a tsunami-like outburst of coal slurry when the gate is opened to transport materials, which could engulf the equipment, facilities, and personnel below and around the silo, causing huge losses such as casualties. If the weight measured by the pressure sensor is lower than the volume of the material multiplied by its density, it indicates that the material is stuck in the silo or clinging to the walls, and cannot flow to the silo discharge port. This indicates that the problem of sticking or clinging to the walls needs to be addressed in time. It is necessary to break up the sticking coal and clear the silo in time to prevent the coal stuck in the walls from suddenly falling and damaging the equipment and facilities below, ensuring the reasonable use of the silo space, and ensuring the smooth and safe operation of coal storage and transportation.

[0023] 8. When the weight measured by the pressure sensor is higher than the allowable value of the corresponding material volume multiplied by the material density, it indicates that the moisture content of the material in the silo exceeds the standard, which can easily cause a silo collapse accident. The silo pressure alarm will sound, prompting urgent anti-collapse measures to be taken. When the weight measured by the pressure sensor is lower than the allowable value of the corresponding material volume multiplied by the material density, it indicates that the material is stuck or clinging to the wall in the silo, and the material cannot flow to the silo discharge port. The silo pressure alarm will sound, prompting that the sticking or clinging problem needs to be dealt with in time. The silo pressure alarm will prompt that the danger of silo collapse must be dealt with immediately through audible and visual alarms. It realizes the automatic discharge of the danger of silo collapse through signal transmission. It automatically controls the opening of the filter anti-collapse gate discharge plate to a certain gap to guide the coal slurry water, so that the coal slurry water flows out gradually in an appropriate amount to prevent the coal slurry water from gushing out when the gate is fully opened, causing a silo collapse accident. When sticking or clinging occurs, the silo pressure alarm prompts that the sticking or clinging must be dealt with in time to ensure efficient and safe production of coal storage and transportation.

[0024] 9. The material moisture detector is installed in the perforated filter structure, in the drainage trough, or between the baffle and the discharge plate of the filter anti-collapse gate. When the material moisture detector is installed in the perforated filter structure, the perforated filter structure includes filter holes, and the material moisture detector is installed on the side or bottom of the filter holes. When the material moisture detector is installed in the drainage trough, the material moisture detector is installed inside the moisture detector trough or on the side wall of the drainage trough. When the material moisture detector is installed between the baffle and the discharge plate of the filter anti-collapse gate, the material moisture detector is installed... At the bottom of the baffle and above the discharge plate of the filter anti-collapse bin, the material moisture detector detects the material humidity, the flow rate of the filtered water, or the water level height of the filtered water per unit time. When the material humidity is too high, the water flow rate is too fast, or the water level height is too high, it indicates that the material moisture in the coal bin exceeds the standard, which may easily cause the bin to collapse. It prompts that the moisture in the bin needs to be treated immediately to avoid the bin collapse. When the material humidity is too low, the water flow rate is too slow, or the water level height is too low, it indicates that the material in the bin is sticking or adhering to the wall. It prompts that the material is sticking or adhering to the wall needs to be treated immediately to ensure smooth, safe and efficient material transfer.

[0025] 10. The material moisture detector detects water flow rate, water level, or material humidity. The moisture display shows the water flow rate, water level, or material humidity value. The material moisture detector includes a moisture detector and a moisture alarm. The moisture alarm and silo pressure alarm are either separate or integrated. The moisture detector detects water flow rate, water level, or material humidity. When the water flow rate, water level, or material humidity is at an abnormal value, the moisture alarm sounds, indicating that the moisture in the silo is excessive and may cause silo collapse, requiring immediate action to control the moisture in the silo. To prevent silo collapse, the system may detect or alert personnel to material buildup or adhesion to the walls, requiring immediate action. It may also display information indicating excessively high or low moisture content. If the moisture content is too high, it indicates that excessive moisture could cause a silo collapse, necessitating immediate action to prevent this. Similarly, if the moisture content is too low, it indicates that material buildup or adhesion to the walls, requiring immediate action. Timely detection and alarms should promptly alert personnel or the intelligent control system to eliminate safety hazards, prevent silo collapse accidents, and prevent material buildup or adhesion from hindering smooth production, ensuring safe and efficient mining operations.

Detailed Implementation Example 1

[0072] like Figures 1 to 4As shown, the silo filtration anti-collapse gate discharge device 1 includes a gate frame 2, a silo filtration anti-collapse gate discharge plate 3, a gate track 4, and a gate opening and closing drive 5. The silo filtration anti-collapse gate discharge plate 3 includes an obtuse-angled anti-collapse gate plate 6, the top of which is raised at an obtuse angle towards the silo opening 7. The gate track 4 includes a roller gate track 8, and the rollers 10 of the roller gate track 8 include roller surfaces 11. The front and rear roller surfaces 11 form a roller surface track 12. The obtuse-angled anti-collapse gate plate 6 has track gate plates 13 on both sides that fit against the surface of the gate track 4. The track gate plates 13 are set on the roller surface track 12 and are connected to the gate opening and closing drive 5. The gate opening and closing drive 5 drives the track gate plates 13 to move the silo filtration anti-collapse gate discharge plate 3. The filter silo gate discharge plate 3 reciprocates along the gate track 4 to open or close the silo opening 7. The obtuse-angled anti-collapse gate plate 6 includes a triangular cross-section filter gate plate 14. The gate frame 2 is equipped with a baffle 16 that cooperates with the obtuse-angled anti-collapse gate plate 6. The baffle 16 is located on the upper side of the obtuse-angled anti-collapse gate plate 6. A filter gap 21 is provided between the baffle 16 and the obtuse-angled anti-collapse gate plate 6. The baffle 16 includes a track baffle 16.1, which is located on the upper part of the gate track 4 and the track gate plate 13. The gate front baffle 16.2 is located on the gate frame 2 in the direction in which the filter silo gate discharge plate 3 reciprocates. When the filter silo gate discharge plate 3 is closed, the front end of the filter silo gate discharge plate 3 and the front part of the gate plate are closed. The baffle 16.2 cooperates to form a baffle-and-filter structure 21.1. The gate frame 2 includes a left arm 2.1 and a right arm. The baffle 16.3 at the rear of the gate is positioned opposite the left arm 2.1 and the right arm 2.2 of the gate frame after the discharge plate 3 of the filter anti-collapse chamber gate is closed. Both ends of the baffle 16.3 are connected to the left arm 2.1 and the right arm 2.2 of the gate frame, respectively, and are supported by the gate frame 2. When the discharge plate 3 of the filter anti-collapse chamber gate is closed, the rear of the discharge plate 3 cooperates with the baffle 16.3 to form the baffle-and-filter structure 21.1. The gate track includes a left gate track 4.1 and a right gate track 4.2. The feeder 16.1 includes a left track upper feeder 16.4 or a right track upper feeder 16.5. The left track upper feeder 16.4 is located on the upper part of the left gate plate track 4.1, and the right track upper feeder 16.5 is located on the upper part of the right gate plate track 4.2. The feeder 16 prevents the material flow, causing the water in the coal bunker to flow out along the obtuse-angled anti-collapse gate plate 6, thus separating the coal and water in the bunker and allowing the filtered water to flow out of the bunker outlet 7. The gate frame 2 includes a collection and drainage trough 17, which includes a lower feeder collection and drainage trough 17.1 located below the feeder 16 to collect the filtered water. The gate track collection and drainage trough 17.2 is located at the gate plate track 4 and is supported by the gate frame 2.The water filtered by the upper filter and anti-collapse gate discharge plate 3 of the gate track 4, in conjunction with the baffle 16, is collected. A collection trough 17 is located at the lower or side of the gate frame 2. The filter and anti-collapse gate discharge plate 3 causes water in the material to flow from a high point to a low point along its inclined surface into the collection trough 17, where the water is collected.

[0073] Alternatively, the gate track 4 may include a planar gate track 9, and the obtuse-angled top anti-collapse chamber gate 6 may have track gates 13 on both sides that fit against the surface of the gate track 4, with the track gates 13 set on the planar gate track 9.

[0074] The gate track 4 or the filter anti-collapse gate discharge plate 3 may also include a drainage trough 17. The gate track and the drainage trough are separate or connected separately or as one piece. The drainage trough 17 is set at the lower part or side of the gate track 4. The filter anti-collapse gate discharge plate 3 allows water in the material to flow from high to low along the inclined surface of the filter anti-collapse gate discharge plate 3 into the drainage trough 17. The drainage trough 17 guides the inflowing water into the water collection container 32.

[0075] Alternatively, the water flowing into the collection and drainage trough 17 can be directed into the water collection container 32 or into the lower waterway.

[0076] The stopper 16 may also include a front stopper 16.2 or a rear stopper 16.3.

[0077] It can also be a drainage trough 17 including a gate track drainage trough 17.2 or a gate frame rear drainage trough 17.3. Example 2

[0078] like Figures 5 to 6 As shown, the silo filtration anti-collapse gate discharge device 1 includes a gate frame 2, a filtration anti-collapse gate discharge plate 3, a gate track 4, and a gate opening and closing drive component 5. The filtration anti-collapse gate discharge plate 3 includes an obtuse-angled anti-collapse gate plate 6, the top of which is raised at an obtuse angle towards the silo opening 7. The obtuse-angled anti-collapse gate plate 6 includes a polygonal cross-section filtration gate plate 15. The gate frame 2 is provided with a baffle 16 that cooperates with the obtuse-angled anti-collapse gate plate 6. The baffle 16 is located on the upper side of the obtuse-angled anti-collapse gate plate 6. The baffle 16 and the obtuse-angled anti-collapse gate plate 6 are connected. A water-filtering gap 21 is provided between the plates 6. The baffle 16 prevents the material flow and causes the water in the coal bunker to flow out along the obtuse-angle top anti-collapse gate 6, so that the coal and water in the bunker are separated and the filtered water flows out of the bunker outlet 7. The water-filtering anti-collapse gate discharge plate 3 includes a collection and drainage trough 17. The collection and drainage trough 17 is set at the lower part or side of the water-filtering anti-collapse gate discharge plate 3. The water-filtering anti-collapse gate discharge plate 3 causes the water in the material to flow from high to low along the inclined surface of the water-filtering anti-collapse gate discharge plate 3 into the collection and drainage trough 17. The collection and drainage trough 17 collects the inflowing water.

[0079] The rest is the same as in Example 1. Example 3

[0080] like Figure 7 As shown, the obtuse-angle top anti-collapse gate 6 includes an obtuse-angle welded anti-collapse gate 18, which is welded from two or more flat plates 20. The two flat plates 20 are aligned and positioned according to the height allowed by the site space to filter water. The two or more flat plates 20 are then welded to form an obtuse-angle welded anti-collapse gate 18 that filters and dries coal slurry water in the coal bunker. The obtuse-angle welded anti-collapse gate 18 has track gates 13 on both sides that fit with the gate track 4, so that the track gates 13 fit with the gate track 4 and reciprocate to quickly close the hopper opening 7.

[0081] The rest is the same as in Example 1. Example 4

[0082] like Figures 8 to 9 As shown, the obtuse-angle top anti-collapse gate 6 includes an obtuse-angle stamped anti-collapse gate 19, which is made of a flat plate 20. The middle of the flat plate 20 is folded into an obtuse-angle stamped anti-collapse gate 19 with a water filtering function using a bending machine. Then, the two sides of the obtuse-angle stamped anti-collapse gate 19 are stamped into track gates 13 that are parallel and fit with the gate track 4, so that the track gates 13 fit with the gate track 4 and reciprocate to quickly close the hopper opening 7.

[0083] The rest is the same as in Example 1. Example 5

[0084] like Figures 10 to 15 As shown, the baffle 16 is fixed to the upper part of the gate frame 2. A water-filtering gap 21 is provided between the baffle 16 and the water-filtering anti-collision gate discharge plate 3, or the baffle 16 is provided with a baffle water filter 22. The baffle 16 and the water-filtering anti-collision gate discharge plate 3 cooperate to prevent material from flowing into the collection and drainage trough 17, ensuring that the water in the coal bunker can be quickly filtered and flow out of the hopper opening 7. The baffle water filter 22 includes a perforated baffle water filter 24. The collection and drainage trough 17 is provided at the lower part or side of the baffle 16. The water-filtering anti-collision gate discharge plate 3 also includes a reinforced anti-collision gate discharge plate 27. The discharge plate 27 improves the load-bearing capacity of the reinforcing gate discharge plate through the bottom reinforcing ribs, ensuring that the water distribution and filtration angles of the gate discharge plate do not deform, and improving the service life of the gate discharge plate. The collection and drainage trough 17 includes a filter-type collection and drainage trough 29, which is equipped with a collection trough filtration structure 31. The collection trough filtration structure 31 filters or purifies the coal slurry water collected by the collection and drainage trough 17 and then guides the water into the waterway or into the water collection container 32. The collection trough filtration structure 31 includes a collection trough hole-type filtration structure 33, a collection trough mesh-type filtration structure, or a collection trough-type filtration structure.

[0085] It can also be a baffle filter 22, including a mesh baffle filter 23, a trough baffle filter 25, a planar baffle filter, or an inclined baffle filter.

[0086] The filter anti-collapse silo gate discharge plate 3 also includes a plate-type anti-collapse silo gate discharge plate 26.

[0087] It can also be a collection and drainage trough 17, including a dredging type collection and drainage trough 30.

When spring-sealed door 50 is installed inside the channel of sedimentation tank 47, sedimentation tank 47 has a rear leakage structure 57 at the rear section of the elastic door panel. The rear leakage structure 57 includes a rear leakage left wall 58, a rear leakage right wall 59, and a rear leakage outlet 60. The rear leakage outlet 60 is connected to the rear leakage left wall 58 and the rear leakage right wall 59. 9.

[0104] like Figures 35 to 39As shown, the silo filtration anti-collapse silo gate discharge device 1 includes a silo pressure measuring mechanism 69, which includes a pressure sensor 70 and a pressure display 71, or the silo pressure measuring mechanism 69 includes a material level detector 74. The gate frame 2 is provided with a support for the pressure sensor 72, and the pressure sensor 70 is located on the upper part of the support for the pressure sensor 72. The gate track includes a silo pressure measuring gate track 73, which is detached from the gate frame 2 and supported by the pressure sensor 70. The filtration anti-collapse silo gate discharge plate 3 is located on the silo pressure measuring gate track 73. When material falls onto the filtration anti-collapse silo gate discharge plate 3, the pressure sensor 70 senses the pressure on the filtration anti-collapse silo gate discharge plate 3, and the pressure display 71 displays the silo pressure value. The pressure sensor 70 directly detects the silo pressure, or the pressure sensor 70 works in conjunction with the material level detector 74 to detect the pressure of the material in the silo. When the pressure sensor 70 works in conjunction with the material level detector 74, the pressure sensor 70 detects the pressure of the material in the silo. 4. When detecting the pressure of the material in the silo, the silo pressure measuring mechanism 69 includes a material weight calculator 75 and a material level detector 74 to detect the height of the material in the silo. The material weight calculator 75 calculates the volume of the material in the silo, and the volume of the material in the silo is multiplied by the material density to calculate the weight of the material in the silo. The volume weight of the material corresponding to the silo opening 7 is relatively stable. That is, the weight of the material measured by the silo pressure should theoretically be the volume of the corresponding material multiplied by the material density. If the weight measured by the pressure sensor 70 is higher than the volume of the corresponding material multiplied by the material density, it indicates that there is moisture in the gaps between the materials in the silo. The larger the weight difference, the greater the moisture content of the material in the silo, indicating that the risk of silo collapse needs to be eliminated in time. If the weight measured by the pressure sensor 70 is lower than the volume of the corresponding material multiplied by the material density, it indicates that the material is stuck or clinging to the wall in the silo and cannot flow to the silo discharge port, indicating that the problem of sticking or clinging needs to be dealt with in time.

[0105] Alternatively, an arc-shaped water diversion gate or a flat gate 20 can be installed on the pressure gate track 73.

When the weight measured by the pressure sensor 70 is higher than the allowable value of the corresponding material volume multiplied by the material density, it indicates that the moisture content of the material in the silo exceeds the standard, which may easily cause a silo collapse accident. The silo pressure alarm 76 will sound an alarm, prompting urgent measures to prevent silo collapse. When the weight measured by the pressure sensor 70 is lower than the allowable value of the corresponding material volume multiplied by the material density, it indicates that the material is stuck in the silo or clinging to the walls, and the material cannot flow to the silo discharge port. The silo pressure alarm 76 will sound an alarm, prompting immediate action. In response to issues such as bulging or wall adhesion, the silo pressure alarm 76 uses audible and visual alarms to alert users to the immediate danger of silo collapse. Through signal transmission, it automatically discharges the risk of collapse and controls the opening of the filter gate's discharge plate 3 to a certain extent, allowing the coal slurry water to flow out gradually and in moderation, preventing a sudden gush of coal slurry water when the gate is fully opened, which could cause a silo collapse. When bulging or wall adhesion occurs, the silo pressure alarm 76 prompts for timely handling to ensure efficient and safe coal storage and transportation.

The moisture detector 84 detects the water flow rate, water level, or material humidity. The moisture display unit 85 displays the water flow rate, water level, or material humidity value, indicating whether the material humidity in the silo is too high or too low. When the material humidity is too high, it indicates that the moisture in the silo is excessive and may cause the silo to collapse, requiring immediate treatment to avoid collapse. When the material humidity is too low, it indicates that the material in the silo is sticking or adhering to the walls, requiring immediate treatment to prevent the material from sticking or adhering to the walls.

It is urgent to deal with the moisture in the silo to avoid the collapse, or it indicates that the material in the silo is sticking to the walls. It is urgent to deal with the material sticking to the walls. Timely detection and alarm will promptly remind personnel or the control system 63 to eliminate the safety hazard.

When the gate opening and closing drive drives the filter gate discharge plate to release material, the rear end seal of the filter gate and the leak-proof component at the rear end of the drainage trough close to prevent mud and water from flowing out from the rear of the drainage trough. When the gate opening and closing drive drives the filter gate discharge plate to release material, the rear end seal of the filter gate and the leak-proof component at the rear end of the drainage trough are automatically opened. The automatic sludge removal structure at the front end of the filter gate discharge plate scrapes the mud and water in the drainage trough backward and automatically falls into the feeder, where it is transported out with the material. This collects and utilizes the material and protects the various components of the conveyor and the electrical control system from corrosion and damage.

6. A silo filtration and anti-collapse gate discharge device according to claim 1 or 5, characterized in that: A sludge sedimentation tank is located at the rear of the drainage trough inside the gate frame. The sedimentation tank includes a guide pipe and a sedimentation tank. The guide pipe can be either a through-hole type or a filter type. The filter type guide pipe includes a filter structure, which is located at the junction of the guide pipe and the sedimentation tank arm. The sedimentation tank collects the sludge filtered by the discharge plate of the filtration gate. The guide pipe discharges the water collected in the sedimentation tank. The sedimentation tank allows the sludge in the sludge to settle. The bottom of the sedimentation tank is level with or lower than the bottom of the drainage trough. The sludge in the drainage trough flows to the sedimentation tank by itself, or an automatic sludge removal mechanism scrapes the sludge from the drainage trough and directs it into the sedimentation tank. An automatic sludge remover is located at the rear end of the discharge plate of the filtration gate. The automatic sludge remover is activated when the gate is closed. The gate is located at the front of the sedimentation tank. A sludge discharge gap is provided between the automatic sedimentation tank sludge remover and the drainage trough. The coal sludge water filtered by the filter gate's discharge plate flows into the sedimentation tank through this gap. As the filter gate's discharge plate moves backward when the discharge is initiated, the automatic sedimentation tank sludge remover automatically adheres to the sedimentation tank wall, scraping the sludge out of the sedimentation tank into the sedimentation tank. The rear of the sedimentation tank is equipped with a spring-sealed door or a magnetic rotating door. The spring-sealed door includes a spring door panel and a telescopic door spring. The rear end of the telescopic door spring is mounted on the gate frame. An elastic door panel is located at the end of the telescopic door spring facing the sedimentation tank. The telescopic door spring pushes the elastic door panel to seal and prevent leakage at the rear of the sedimentation tank. The elastic door panel can be a flat elastic door panel or a sealing elastic door panel. The door panel is equipped with door panel seals around its perimeter. The spring-loaded telescopic door panel pushes against these seals to prevent water leakage from the sedimentation tank. The spring-loaded door directly pushes against the rear end of the sedimentation tank, sealing it. Alternatively, the spring-loaded door can be installed within the sedimentation tank channel. When the spring-loaded door is installed within the sedimentation tank channel, the sedimentation tank has a rear material leakage structure at the rear of the elastic door panel. This rear material leakage structure includes a left rear material leakage wall, a right rear material leakage wall, and a rear material leakage outlet. The opening and closing angles of the rear material leakage outlet, left rear material leakage wall, and right rear material leakage wall are the same. Alternatively, the left rear material leakage wall and right rear material leakage wall face the rear material leakage outlet and have a left and right supporting elastic door panel platform, respectively. When the elastic door panel is pushed to the rear material leakage structure, the left supporting elastic door panel... The platform and right-hand elastic gate ensure the elastic gate moves back and forth within the sedimentation tank channel. The elastic gate accurately seals the rear of the sedimentation tank or allows the scraped sediment to enter the discharge port behind the gate, flowing into the feeder and being transported out with the material. The elastic gate is equipped with a gate sealing element around its perimeter, the area of ​​which is larger than the cross-sectional area of ​​the sedimentation tank channel, ensuring a tight seal. The rear end of the filter anti-collapse gate discharge plate is equipped with an opening spring sealing door mechanism or an opening magnetic door mechanism. When the gate opening and closing drive drives the filter anti-collapse gate discharge plate backward, the spring sealing door mechanism opens, causing the telescopic gate spring to retract. Simultaneously, it pushes the sludge from the sedimentation tank to the discharge structure behind the gate. The sludge in the sedimentation tank is scraped and pushed through the discharge port behind the gate, falling into the feeder.The magnetic rotating door, located at the rear end of the sludge sedimentation tank, is transported out along with the materials. A rotating shaft is positioned at the upper rear end of the sedimentation tank, and the magnetic rotating door has a rotating door sleeve that mates with this shaft. The rotating door sleeve passes through the rotating shaft. An adsorption magnet is located at the rear end of either the magnetic rotating door or the sedimentation tank. The magnetic rotating door adheres to the rear end of the sedimentation tank, sealing it. Opening the magnetic door mechanism pushes the magnetic rotating door open, simultaneously pushing the sludge from the sedimentation tank onto the feeder conveyor belt.

7. The silo filtration and anti-collapse gate discharge device according to claim 1, characterized in that: The silo filtration and anti-collapse silo gate discharge device includes a silo pressure measuring mechanism, which includes a pressure sensor and a pressure display, or a material level detector. The gate frame is equipped with a support for the pressure sensor, which is positioned above it. The gate track includes a silo pressure measuring gate track, which is detached from the gate frame and supported by the pressure sensor. The silo filtration and anti-collapse silo gate discharge plate is positioned on the silo pressure measuring gate track. When material falls onto the silo filtration and anti-collapse silo gate discharge plate, the pressure sensor senses the pressure on the discharge plate, and the pressure display shows the silo pressure value. The pressure sensor directly detects the silo pressure, or it works in conjunction with the material level detector to detect the pressure of the material inside the silo. When the pressure sensor works with the material level detector to detect the pressure of the material inside the silo, the silo pressure measuring mechanism... The system includes a material weight calculator, a material level detector to measure the height of the material in the silo, a material weight calculator to calculate the volume of the material in the silo, and a material weight multiplied by the material density to calculate the weight of the material in the silo. The volumetric weight of the material corresponding to the silo opening is relatively stable, meaning that the weight of the material measured by the silo pressure sensor should theoretically be the volume of the material multiplied by the material density. If the weight measured by the pressure sensor is higher than the volume of the material multiplied by the material density, it indicates that there is moisture in the gaps between the materials in the silo. The larger the weight difference, the higher the moisture content of the material in the silo, indicating that the risk of silo collapse needs to be eliminated in time. If the weight measured by the pressure sensor is lower than the volume of the material multiplied by the material density, it indicates that the material is stuck or clinging to the walls of the silo and cannot flow to the silo discharge port, indicating that the problem of sticking or clinging needs to be addressed in time.

8. The silo filtration and anti-collapse gate discharge device according to claim 1, characterized in that: The silo pressure monitoring mechanism includes a silo pressure alarm. When the weight measured by the pressure sensor is higher than the allowable value of the corresponding material volume multiplied by the material density, it indicates that the moisture content of the material in the silo exceeds the standard, which may easily cause a silo collapse. The silo pressure alarm will sound, prompting urgent anti-collapse measures to be taken. When the weight measured by the pressure sensor is lower than the allowable value of the corresponding material volume multiplied by the material density, it indicates that the material is stuck or clinging to the walls of the silo, and the material cannot flow to the silo discharge port. It prompts that the sticking or clinging problem needs to be dealt with in time. The silo pressure alarm prompts the need to deal with the danger of silo collapse immediately through audible and visual alarms. It realizes the automatic discharge of the danger of silo collapse through signal transmission. It automatically controls the opening of the discharge plate of the filter anti-collapse gate to a certain gap to guide the coal slurry water, so that the coal slurry water flows out gradually and in an appropriate amount, preventing the coal slurry water from gushing out when the gate is fully opened, causing a silo collapse accident. When sticking or clinging occurs, the silo pressure alarm prompts the need to deal with the sticking or clinging in time, ensuring efficient and safe production of coal storage and transportation.

9. A silo filtration and anti-collapse gate discharge device according to claim 1, characterized in that: The silo filtration and anti-collapse gate discharge device includes a material moisture detector. The material moisture detector is installed in a perforated filtration structure, a drainage trough, or between a baffle and the discharge plate of the silo filtration and anti-collapse gate. When the material moisture detector is installed in a perforated filtration structure, the perforated filtration structure includes filtration holes, and the material moisture detector is installed on the side or bottom of the filtration holes. When the material moisture detector is installed in a drainage trough, the drainage trough includes a moisture detector slot or a side wall of the drainage trough, and the material moisture detector is installed inside the moisture detector slot or on the side wall of the drainage trough. When the material moisture detector is installed between the baffle and the discharge plate of the silo filtration and anti-collapse gate, the material moisture detector is installed at the bottom of the baffle and at the top of the discharge plate of the silo filtration and anti-collapse gate.

10. A silo filtration and anti-collapse gate discharge device according to claim 1, 8, or 9, characterized in that: Material moisture detectors include digital display material moisture detectors or alarm material moisture detectors. Digital display material moisture detectors include a moisture detector and a moisture fraction display. The moisture detector detects water flow velocity, water level, or material humidity. The moisture fraction display shows the water flow velocity, water level, or material humidity value. Alarm material moisture detectors include a moisture detector and a moisture alarm. The moisture alarm and silo pressure alarm are either separate or integrated. When the water flow velocity, water level, or material humidity is abnormal, the moisture alarm sounds, indicating that the moisture in the silo is excessive and may cause silo collapse, requiring immediate action to control the moisture and prevent collapse. Alternatively, it may indicate that the material in the silo is sticking or adhering to the walls, requiring immediate action. It may also indicate that the material humidity in the silo is too high or too low. When the material humidity is too high, it indicates that the moisture in the silo is excessive and may cause silo collapse, requiring immediate action to control the moisture and prevent collapse. When the material humidity is too low, it indicates that the material in the silo is sticking or adhering to the walls, requiring immediate action. Timely detection and alarm prompt personnel or the control system to immediately eliminate safety hazards.
