Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, and more specifically to a bar screen slag removal system for removing small amounts of slag. Background Technology

[0002] With current water scarcity and escalating environmental pollution, the wastewater treatment industry is crucial for protecting the aquatic ecosystem. External municipal pipe networks collect domestic, industrial, and surface wastewater to treatment plants, where it undergoes multiple treatment processes to meet standards before being discharged or reused. Bar screens are a key step in wastewater pretreatment, intercepting suspended impurities, preventing blockages in subsequent equipment, and ensuring system stability.

[0003] The slag removal process is divided into three stages according to the gap: coarse screen (10-100mm) initially screens out large impurities, fine screen (3-10mm) removes medium impurities, and fine screen (<3mm) intercepts millimeter- or even micron-sized impurities such as fine fibers and micro-plastics, providing high-quality feed water for subsequent processes.

[0004] In the initial coarse and fine screen stages, the slag is large in size, low in moisture content, and abundant in quantity. Traditional screen presses reduce the volume through compression, facilitating transportation and disposal, with ideal results. However, in the fine screen stage, the slag is extremely small in size, less abundant in quantity, and highly viscous. The shortcomings of traditional equipment become apparent: firstly, the slag removal efficiency is low, as the screen gaps are insufficient to trap fine slag, resulting in a large amount of slag being lost with the wastewater; secondly, energy consumption is high, requiring increased power, speed, or pressure to trap slag, leading to an imbalance between energy consumption and processing capacity, and increasing operating costs.

[0005] These problems restrict the slag removal effect of fine bar screens, affect the overall processing efficiency, increase operating costs and environmental risks, and urgently require improvement of traditional equipment or development of new slag removal equipment to meet the needs of high efficiency and low consumption. Summary of the Invention

[0006] This invention provides a bar screen slag removal system for removing small amounts of slag, with the aim of being able to meet the interception requirements of small amounts of fine slag.

[0007] The present invention is achieved through the following technical solution: a bar screen slag removal system for removing small amounts of slag, comprising a transport vehicle, a slag remover and a slag removal chamber, wherein the slag remover is located in the slag removal chamber, the top of the slag removal chamber is connected to a water inlet pipe and the bottom of the slag removal chamber is connected to a water outlet pipe;

[0008] The top of the slag remover is an open end, which is directly opposite the inlet pipe; the bottom of the slag remover is equipped with a filter plate, so that liquid entering the slag remover can flow out through the filter plate and be discharged through the outlet pipe; the transport vehicle is detachably connected to the slag remover.

[0009] Compared with existing technologies, this solution has the following advantages and beneficial effects:

[0010] One of the slag removal systems in this solution, designed for removing small amounts of slag, features an open end facing the inlet pipe, ensuring that the slag-water mixture transported from the front end falls precisely into the slag remover, preventing slag loss due to overflow. Combined with the targeted filtration of the filter plate at the bottom of the slag remover, it is suitable for intercepting small amounts of fine slag, efficiently separating wastewater and slag. The filtered wastewater is smoothly discharged through the outlet pipe of the slag removal chamber, ensuring that the slag is retained within the slag remover. This solves the problem of incomplete slag collection and low separation efficiency in traditional equipment designed for large amounts of slag.

[0011] This invention relates to downstream wastewater treatment processes, replacing traditional bar screen presses with bar screen removal systems designed for small quantities of slag. These systems utilize a gravity-fed mixture of slag and wastewater, filtering out the wastewater and retaining the slag. Once a sufficient amount of slag has been collected, it is transported off-site. This invention is applicable only to bar screens with low slag output and offers advantages over traditional bar screen presses, including energy saving, simpler mechanical structure, and higher equipment utilization efficiency.

[0012] The detachable design of the transport vehicle and the slag remover eliminates the need for complex mechanical transmission structures to transfer slag. Once a certain amount of slag has accumulated in the slag remover, the operator only needs to separate or connect the transport vehicle and the slag remover. Compared to the complex process of traditional bar screen presses that rely on a power system to complete the pressing and conveying, this greatly simplifies manual operation, reduces the labor intensity of operators, and shortens the operation time for each slag transport.

[0013] In this solution, the slag removal machine has no complex extrusion or drive components, and separation is achieved only through the filter plate; the transport vehicle is mainly moved manually and has no power components; the slag removal chamber only needs to ensure water inlet and drainage and protection functions. The overall number of components is small and the failure rate is low. Later maintenance only requires regular cleaning of the filter plate and inspection of the detachable mating structure, which significantly reduces the operation and maintenance costs and cycle.

[0014] In addition, the system relies entirely on gravity to complete key processes: the sludge-water mixture falls naturally into the sludge remover through the inlet pipe (no pump required), the wastewater flows through the filter plate and then flows by gravity to the outlet pipe of the sludge removal chamber (no additional pressurization required), and the transport vehicle completes the sludge transportation by manual pushing (no power required). Compared with traditional bar screen presses that require electricity to drive the pressing rollers, conveyor chains and other components, this system achieves zero power consumption to complete the removal and transportation of a small amount of sludge, significantly reducing energy consumption in the wastewater treatment process.

[0015] The size of the slag remover, the aperture of the filter plate, and the capacity of the transport vehicle are all adapted to the collection and transportation needs of small amounts of slag. There is no need to reserve redundant functions to accommodate large amounts of slag, reducing material consumption during equipment manufacturing, lowering equipment idle rates, and improving the functional utilization rate of unit components, aligning with the "low-carbon, high-efficiency" operation trend in the wastewater treatment industry. The overall system structure is compact, and the slag removal chamber can be flexibly installed according to the site layout of the downstream wastewater treatment. The inlet and outlet pipes can be easily connected to the existing wastewater pipe network, achieving seamless integration with downstream processes without large-scale modifications to the original wastewater treatment process. This solves the problem of poor adaptability to various scenarios caused by the large size and complex installation of traditional large-scale slag removal equipment.

[0016] Furthermore, the bottom of the slag removal chamber is connected to four support platforms, and the four support platforms are arranged in a rectangular array at the bottom of the slag removal chamber. The bottom of the slag removal machine is placed on the plane formed by the four support platforms. The transport vehicle includes a bottom plate and a vertical plate that are perpendicularly connected to each other. The bottom of the vertical plate is connected to a traveling wheel. The bottom plate of the transport vehicle can move between the support platforms on both sides and be located below the slag removal machine.

[0017] Beneficial effects: The four rectangular array support platforms in this solution provide a balanced and stable support plane for the slag remover, avoiding tilting or displacement caused by uneven local stress due to long-term bearing of slag-water mixture. This ensures that the core positioning of the slag remover's open end is always accurate, and the slag-water mixture can fall stably into the slag remover, solving the problems of feed deviation and slag-water overflow that are easily caused by traditional single support or asymmetrical support.

[0018] The support platform separates the bottom of the slag remover from the floor of the slag removal chamber, creating a gap space at a specific height. This space provides a smooth flow channel for wastewater to pass through the filter plate and flow to the outlet pipe at the bottom of the slag removal chamber, preventing the filtration efficiency from decreasing due to wastewater accumulation at the bottom of the slag remover. It also prevents residual wastewater on the floor of the slag removal chamber from directly contacting the bottom of the slag remover, reducing rust damage caused by long-term immersion and extending the service life of the equipment. In addition, it facilitates the cleaning and maintenance of the bottom of the slag removal chamber (such as removing deposited impurities) and provides space for the transport vehicle's floor to be moved under the slag remover.

[0019] The transport vehicle's floor can be moved between the two support platforms and located below the slag remover. This design makes full use of the gap space formed by the support platforms. The rectangular array layout of the support platforms provides a precise moving channel for the transport vehicle's floor, allowing the vehicle to enter and exit without needing to expand the slag removal chamber space.

[0020] Finally, the wheels at the bottom of the vertical platform of the transport vehicle in this solution transform the traditional sliding and pushing motion into rolling and pushing motion, significantly reducing frictional resistance during waste transportation. Even when the bottom platform carries a certain amount of waste, operators can easily push the transport vehicle to complete the transfer, solving the problems of high labor intensity and low transportation efficiency caused by the manual dragging of traditional wheelless trolleys. At the same time, the mutually perpendicular bottom platform and vertical platform form an L-shaped structure, with the vertical platform serving as a stable handrail during pushing, making it easier for operators to control the direction of the trolley and preventing waste spillage due to directional deviation during transportation, thus improving the safety of waste transportation.

[0021] Furthermore, a mounting bracket is connected to one side and top of the slag remover, and an mounting plate is connected to the top of the vertical plate. A buckle is rotatably connected to the mounting plate, and rotating the buckle can engage and lock or disengage and unlock the buckle from the mounting bracket.

[0022] Beneficial effects: This solution achieves a detachable connection between the slag remover and the transport vehicle by locking or unlocking the buckle and the seat. This operation method is simple and convenient, and the locking or unlocking state can be quickly achieved by manually rotating the buckle.

[0023] Furthermore, the buckle and the mounting plate are rotatably connected via a pivot, and the buckle is provided with an elastic component, which is used to provide auxiliary elastic force for the buckle to engage.

[0024] Beneficial effects: The elastic component provides auxiliary spring force for the latch engagement. When the transport vehicle is pushed under the slag remover and the latch needs to engage with the mounting bracket, the pre-tightening force of the elastic component drives the latch to automatically rotate towards the mounting bracket. The operator only needs to slightly push the latch to complete the engagement and locking, eliminating the need for completely manual rotation of the latch to the engaged position. This significantly reduces the force required, especially for operators with limited physical strength. Compared to purely manual latches without elastic components, this shortens the engagement and locking operation time and further improves work efficiency.

[0025] When the latch is rotated in the reverse direction to unlock the transport vehicle, the elastic component can automatically reset the latch to its initial ready-to-lock state (such as parallel to the top of the slag remover or slightly raised), eliminating the need for manual repositioning. This design avoids positional shifts caused by haphazard placement after unlocking (requiring readjustment for the next locking operation), and also prevents the latch from colliding and wearing with other components (such as the transport vehicle's vertical plate) due to prolonged non-reset status, extending the latch's service life. Simultaneously, it prepares the latch for the next locking operation, reducing the reset and adjustment steps in the operational process.

[0026] Furthermore, the elastic component can be configured in at least one of the following ways: the elastic component is a torsion spring sleeved on the rotating shaft, with both ends of the torsion spring abutting against the inner wall of the buckle and the side wall of the mounting plate, respectively; or the elastic component is a spring connected between the buckle and the vertical plate.

[0027] Beneficial effects: The design of the torsion spring sleeved with the rotating shaft in this solution ensures that the direction of its elastic force is completely consistent with the rotation trajectory of the buckle around the rotating shaft (along the tangent direction of the rotating shaft's circumference), which can provide the buckle with an auxiliary elastic force without deviation: when engaged, the torsion spring force precisely drives the buckle to rotate towards the buckle seat, avoiding buckle jamming due to deviation of the elastic force direction; after unlocking, the torsion spring resets itself through its own torsion, driving the buckle to smoothly return to the ready-to-engage state.

[0028] The spring-loaded design connecting the buckle and the vertical plate provides directional tension or thrust depending on the engagement direction: if the buckle needs to rotate towards the vertical plate for engagement, the spring provides tension assistance; if engagement needs to be performed away from the vertical plate, the spring provides thrust support. This directional elastic force acts directly on the mating point between the buckle and the vertical plate, further enhancing the locking strength.

[0029] Furthermore, guide grooves are provided on both sides of the lower part of the slag remover. The guide grooves are through grooves. Support wheels are rotatably connected to the support platform. The top of the support wheels is supported on the top wall of the guide groove.

[0030] Beneficial effects: The top of the support wheel supports the top wall of the guide groove, converting the sliding friction between the slag remover and the support platform into rolling friction. When it is necessary to process the impurities collected in the slag remover, the operator does not need to use hoisting equipment. He only needs to connect the slag remover to the transport vehicle and pull the slag remover to be pulled out of the slag removal chamber along the direction of the guide groove.

[0031] Furthermore, the slag remover is equipped with two slag baffles, both of which are vertically arranged along the height direction of the slag remover and are located at the two side edges of the filter hole area of ​​the filter plate, and the slag baffles are connected to the inner wall of the slag remover.

[0032] Beneficial effects: The vertical setting and edge positioning of the baffle plate can guide the distribution of slag within the filter hole area: When the slag-water mixture impacts the slag remover, the baffle plate can buffer the impact force of the water flow and prevent slag from accumulating on one side due to the water flow (leading to local filter hole blockage and other filter holes being idle).

[0033] Furthermore, the left and right baffle plates are vertically installed on both sides inside the slag remover. This prevents the slag-water mixture from splashing to both sides due to inertia when it enters the slag remover, thus avoiding fine slag from adhering to the side wall of the slag remover or overflowing from the equipment gaps. At the same time, it prevents slag from scattering to both sides due to external forces (such as slight collisions when manually pushing a cart) during the temporary storage process, ensuring that the slag is always concentrated in the effective collection area of ​​the filter plate.

[0034] Furthermore, the top of the slag baffle extends beyond the top of the slag remover, and slots for inserting and engaging with the slag baffle are provided on both sides of the slag remover, allowing the slag baffle to be inserted into or removed from the slots.

[0035] Beneficial effects: The baffle plate, through its engagement with the slot, allows for a detachable connection with the slag remover, facilitating its later removal for cleaning or replacement. In this design, the baffle plate extends beyond the slag remover, simplifying removal and enhancing its shielding effect, preventing slag from splashing out and contaminating the top of the slag removal chamber or surrounding equipment.

[0036] Furthermore, the base plate has a water collection cavity inside, a drain plate is connected to the top of the base plate, the drain plate has multiple drain holes communicating with the water collection cavity, and a drain valve is connected to one side of the base plate.

[0037] Beneficial effects: The drain plate at the top of the vertical plate and the connected water collection chamber can collect the residual water inside the slag remover while the slag remover is supported by the bottom plate of the transport vehicle, thus preventing residual liquid from leaking out and polluting the environment during transportation. The liquid in the water collection chamber can be discharged in a concentrated manner by opening the drain valve later.

[0038] Furthermore, the slag removal chamber is equipped with a cleaning unit for cleaning the slag removal machine. The cleaning unit includes a spray pipe and multiple nozzles, with the multiple nozzles installed at intervals on the spray pipe. The cleaning unit is located above the slag removal machine.

[0039] Beneficial effects: After the transport vehicle delivers the slag remover to the designated location to process the slag collected inside, it is transported back to the slag removal chamber. The cleaning unit can then be opened to clean the slag remover and reuse it. Attached Figure Description

[0055] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of the present invention are only used to explain the present invention and are not intended to limit the present invention.

[0056] As one embodiment of this application, such as Figure 1 , Figure 2 and Figure 3 As shown, this embodiment provides a bar screen slag removal system for removing small amounts of slag, including a transport vehicle 1, a slag remover 2, and a slag removal chamber 6. The slag remover 2 is located inside the slag removal chamber 6. The top of the slag removal chamber 6 is connected to a water inlet pipe 4, and the bottom of the slag removal chamber 6 is connected to a water outlet pipe 5.

[0057] The top of the slag remover 2 is an open end, and the open end of the slag remover 2 is directly opposite the water inlet pipe 4; combined with Figure 7 As shown, a filter plate 204 is provided at the bottom of the slag remover 2. The filter holes 205 on the filter plate 204 are distributed in a rectangular array. The liquid entering the slag remover 2 can flow out through the filter plate 204 and be discharged through the outlet pipe 5. The bar screen conveys the filtered slag-water mixture into the slag remover 2 in the slag removal chamber 6 through the inlet pipe 4. The slag remover 2 collects the slag and filters out the wastewater. The filtered wastewater is discharged to the designated location through the outlet pipe 5.

[0058] The transport vehicle 1 and the slag remover 2 can be detachably connected, such as Figure 1 As shown, in this embodiment, the bottom of the slag removal chamber 6 is connected to four support platforms 7. The four support platforms 7 are arranged in a rectangular array at the bottom of the slag removal chamber 6. The bottom of the slag removal machine 2 is placed on the plane formed by the four support platforms 7. The slag removal machine 2 is in the shape of a rectangular box. The four support platforms 7 can raise and support the slag removal machine 2.

[0059] like Figure 2 As shown, the transport vehicle 1 includes a base plate 101 and a vertical plate 102 that are perpendicularly connected to each other. In this embodiment, the base plate 101 and the vertical plate 102 are welded and fixed. The bottom of the vertical plate 102 is connected to a traveling wheel 109. The traveling wheel 109 can reduce the friction with the ground, making the transport vehicle 1 move more smoothly. The base plate 101 of the transport vehicle 1 can move between the support platforms 7 on both sides and be located below the slag remover 2.

[0060] After the support platform 7 raises and supports the slag remover 2, the resulting space facilitates the movement of the transport vehicle 1's base plate 101 under the slag remover 2. Figure 3 As shown, when the transport vehicle 1 and the slag remover 2 are connected and cooperate with each other, it is convenient to use the transport vehicle 1 to pull the slag remover 2 out of the slag removal chamber 6 and move it to a designated location to collect and process the slag inside the slag remover 2.

[0061] In one embodiment, such as Figure 2 As shown, a handle 104 is connected to the upper part of the vertical plate of the transport vehicle. The handle 104 is inclined. In this embodiment, when the transport vehicle is pushed, the handle 104 is designed to facilitate manual gripping to push or pull the transport vehicle.

[0062] In one embodiment, such as Figure 1 As shown, in this embodiment, a mounting bracket 202 is connected to one side and top of the slag remover 2, combined with... Figure 2 As shown, the top of the vertical plate 102 is connected to the mounting plate 103. In this embodiment, the mounting plate 103 is welded and fixed to the top of the vertical plate 102. A buckle 105 is rotatably connected to the mounting plate 103. Rotating the buckle 105 can lock or unlock the buckle 105 with the card seat 202, thereby realizing the detachable cooperation between the slag remover 2 and the transport vehicle 1.

[0063] In one embodiment, the buckle 105 and the mounting plate 103 are rotatably connected by a rotating shaft. In this embodiment, the inner side of the buckle 105 is provided with a vertical surface that engages with the card seat 202. The card seat 202 has a right-angled triangular structure. When the buckle 105 is engaged on the card seat 202, the right-angled surface of the buckle 105 and the vertical surface of the card seat 202 come into contact and match each other, thereby realizing the detachable engagement of the transport vehicle 1 and the slag remover 2. At this time, the transport vehicle 1 can pull the slag remover 2 to move together.

[0064] In this embodiment, the buckle 105 is provided with an elastic component, which provides auxiliary elastic force for the buckle 105 to engage. The elastic component can be configured in at least one of the following embodiments.

[0065] In one embodiment, such as Figure 4 As shown, the elastic component is a torsion spring 111 sleeved on the rotating shaft, and the two ends of the torsion spring 111 abut against the inner wall of the buckle 105 and the side wall of the mounting plate 103, respectively.

[0066] In one embodiment, such as Figure 2 As shown, the elastic component is a spring 110 connected between the buckle 105 and the vertical plate 102, and the spring 110 is a compression spring 110.

[0067] In one embodiment, such as Figure 5 and Figure 6 As shown, guide grooves 201 are provided on both sides of the lower part of the slag remover 2. The guide grooves 201 are through groove structures. Support wheels 8 are rotatably connected to the support platform 7 via a rotating shaft. The top of the support wheels 8 is supported on the top wall of the guide grooves 201. This reduces the resistance to the movement of the slag remover 2 during removal, allowing the slag remover 2 to be pulled out of the slag removal chamber 6 more smoothly.

[0068] In one embodiment, such as Figure 6 As shown, in this embodiment, there are two card holders 202 on the slag remover 2. The two card holders 202 are located on both sides of the slag remover 2. Correspondingly, there are also two buckles 105 on the top of the vertical plate 102. The two buckles 105 cooperate with the two card holders 202 buckles 105 respectively.

[0069] In one embodiment, such as Figure 5 As shown, the slag remover 2 is equipped with two slag baffles 203. Both slag baffles 203 are vertically arranged along the height direction of the slag remover 2, and the two slag baffles 203 are located at the two sides of the filter hole 205 area of ​​the filter plate 204. The slag baffles 203 are connected to the inner wall of the slag remover 2. In this embodiment, the two slag baffles 203 can guide the slag to be distributed in the filter hole 205 area, ensuring that the slag is always concentrated in the effective collection area of ​​the filter plate 204.

[0070] In one embodiment, in this embodiment, combined with Figure 5 As shown, the top of the slag baffle 203 extends out of the top of the slag remover 2, and slots that can be inserted into and cooperate with the slag baffle 203 are provided on both sides of the slag remover 2. The two sides of the slag baffle 203 can be inserted into the slots or pulled out from the slots.

[0071] In this embodiment, the slag baffle 203 is inserted into the slot, which facilitates the installation and removal of the slag baffle 203.

[0072] In one embodiment, such as Figure 4 As shown, the base plate 101 has a water collection cavity 107 inside, and a drain plate 106 is connected to the top of the base plate 101. The drain plate 106 has multiple drain holes communicating with the water collection cavity 107. A drain valve 108 is connected to one side of the base plate 101. In this embodiment, the drain plate 106 is fixed to the base plate 101 by welding or bolting.

[0073] In this embodiment, after the base plate 101 is inserted into the space of the two side support platforms 7 and is located below the slag remover 2, by rotating the buckle 105, the buckle 105 is engaged with the buckle seat 202 on the top of the slag remover 2. Then, by pulling the transport vehicle 1, the transport vehicle 1 can drive the slag remover 2 to move synchronously. The liquid remaining inside the slag remover 2 will flow out from its internal filter plate 204 to the top of the base plate 101 of the transport vehicle 1.

[0074] Since the bottom plate 101 is connected to the top of the drain plate 106 in this embodiment, the liquid flowing out from the bottom of the slag remover 2 will flow from the drain hole of the drain plate 106 to the water collection chamber 107 for collection, so as to avoid the liquid flowing out from the bottom plate 101 from overflowing and polluting the environment during transportation.

[0075] By opening the drain valve 108, the liquid inside the water collection chamber 107 can be drained.

[0076] In one embodiment, such as Figure 8 As shown, in this embodiment, a cleaning unit for cleaning the slag remover 2 is provided in the slag removal chamber 6. The cleaning unit includes a spray pipe 3 and multiple nozzles 301, which are spaced apart on the spray pipe 3. The cleaning unit is located above the slag remover 2. The spray pipe 3 is connected to a high-pressure water supply unit through a pipeline. Water is supplied to the spray pipe 3 by the high-pressure water supply unit (such as a high-pressure pump) and sprayed out through the nozzles 301.

[0077] In this embodiment, the bar screen conveys the filtered sludge-water mixture into the sludge remover 2 to collect the sludge, while the wastewater is filtered out through the filter plate 204. Because the amount of sludge collected in the sludge remover 2 is small, collection takes a relatively long time. Once a certain amount has been collected, and it is confirmed manually that it is ready for transport, the bottom plate 101 of the transport vehicle 1 is pushed under the sludge remover 2. By rotating the buckle 105 to lock the bracket 202 on top of the sludge remover 2, it can be pulled out and transported to a designated garbage bin. After being transported back, the cleaning unit is opened to clean the sludge remover 2 for reuse.

[0078] It should be noted that the above description of the disclosed embodiments enables those skilled in the art to implement or use this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the scope of this application. Therefore, this application is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
