Description

Technical Field

[0001] The utility model belongs to the technical field of mining machinery equipment, in particular to a scraper gate which is not prone to material accumulation. Background Art

[0002] The production activities of mining enterprises usually involve digging out mineral raw materials buried underground, and then processing them into raw materials or fuels for industrial production. Such as coal mines, iron mines, copper mines, lead-zinc mines, etc. In the process of mining and processing, minerals inevitably have to go through processes such as crushing, screening, diversion, transportation, and storage. In the material processing and production process, temporary storage, grading, diversion, and transportation are common things, and they are also the most important production links. For example: the upper conveyor is transferred to the lower conveyor, and the material is transferred to the temporary storage warehouse. For example, it is released from the warehouse to the next processing and production process, or the finished product is released from the storage warehouse and loaded into a train or car for external sales. The general mining production process {ore raw materials-transfer-crushing-transfer-grain classification-grading transfer and diversion-re-crushing-transfer-specific gravity classification-grading transfer and diversion-fine processing and purification (slag discharge)-transfer and diversion-finished product warehouse (tailings warehouse)-transfer and loading trains or cars for external transportation and sales (external transportation of tailings)} is this process, and finally the mineral raw materials and tailings are separated. For example, coal mines are divided into coal (raw coal, clean coal, coking coal, power fuel coal, and tailings slime) and gangue, iron ore is divided into iron ore powder and tailings, and lead-zinc ore is divided into lead ore powder, zinc ore powder, and tailings.

[0003] During the transportation of raw coal from coal mines, the goods are distributed to the lower-level processing equipment (for example, the raw coal on the same transportation line is divided into two and distributed to two crushers for crushing; another example is: the raw coal on the same transportation line is divided into four and distributed to four vibrating screens for screening; another example is that the commercial coal stored in the same silo is divided into three discharge ports and quickly discharged out of the silo and loaded onto cars (or trains) for export. Each discharge (distribution) outlet must use a flat gate, which discharges the goods when it is opened and stops discharging when it is closed. The flat gate is opened to discharge the goods, and the goods flow downward rapidly under the action of gravity, and at the same time, an air flow carrying dust is generated and sprayed out.

[0004] However, it still has the following disadvantages in actual use:

[0005] 1. The traditional flat gates used in existing mines inevitably have gaps in their structure, which leads to dust spilling out with the airflow. Passive blocking or timely cleaning can only treat the symptoms but not the root cause. Dust spillage is very harmful, polluting the air in the plant space and harming the health of employees. The concentration of dust after collection is explosive under certain conditions;

[0006] 2. The traditional flat gates used in existing mines need to open and close in the idle section, so dust will be brought out when the flat gate moves, causing dust to overflow into the external environment. Dust overflow still exists and it is difficult to deal with the dust. For this reason, we provide a scraper gate that is not easy to accumulate materials to solve the above problems. Utility Model Content

[0007] The utility model aims to provide a scraper conveyor gate which is not easy to accumulate materials. By setting an adjustment component, the gate plate can be adjusted to open and close in a completely sealed space without any connection with the outside. The coal powder dust generated by the coal flow and the air flow has no passage and gap to diffuse outward, so that dust can be avoided from overflowing and causing harm to the health of employees. The filter cloth in the filter frame can be used to filter the dust-containing airflow to further prevent dust from overflowing. At the same time, the filter cloth can be flushed with water by a water jet pipe and a nozzle to prevent dust or naked particles from accumulating and hindering the gate plate from sliding on the slide. The filter cloth can be flushed clean with clean water regularly or irregularly.

[0008] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0009] The utility model is a scraper gate which is not easy to accumulate materials, comprising a gate body and an idle section frame installed on the top of the outer wall of one side thereof, a feed frame and a discharge frame are installed on the top and bottom of the gate body respectively, an adjustment component is arranged inside the gate body, a filter frame is installed on the bottom end of the idle section frame, and water jet pipes are evenly installed from front to back on the outer wall of the idle section frame;

[0010] The regulating component comprises a gate plate and supporting plates fixedly connected to the front and rear ends of one side of the bottom plate thereof, and a vertical slide wheel is installed at the bottom of the supporting plate.

[0011] The utility model is further configured that an upper cover plate is installed on the top of the idle section frame, an adjustment groove is arranged below the inner wall of one side of the idle section frame, and a telescopic movable cylinder is slidably connected to the upper inner portion of the feed frame.

[0012] The utility model is further configured that a support is slidably connected to the lower part of the discharge frame, and a baffle is fixedly connected to the bottom edge of the inner wall on the other side of the idle section frame.

[0013] The utility model is further configured that a limiting component is arranged inside the adjusting groove, and the limiting component comprises a limiting plate and a pull ring installed at the center position of the outer wall thereof.

[0014] The utility model is further configured that the inner wall of the limit plate is evenly and fixedly connected with connecting rods from front to back, and the other end of the connecting rod passes through the through hole on the outer wall of the adjustment groove and is connected with the clamping plate.

[0015] The utility model is further configured that a spring is sleeved on the outer side of the outer wall of the connecting rod, and the spring is located between the inner wall of the adjusting groove and the clamping plate.

[0016] The utility model is further configured such that free-running smooth track wheels are rotatably connected to the front and rear ends of the outer side of the upper surface of the gate plate, an oil cylinder is installed below the outer wall of the support plate, and one side of the outer wall of the oil cylinder is fixedly connected to the outer wall of the gate body through a square flange.

[0017] The utility model is further configured that a filter cloth is installed inside the filter frame, a nozzle is installed at the other end of the water jet pipe, and the nozzle penetrates the outer wall of the idle section frame and is placed inside the outer wall.

[0018] The utility model has the following beneficial effects:

[0019] 1. The utility model sets an adjustment component, which can adjust the gate to open and close in a completely sealed space under the action of the oil cylinder. It has no connection with the outside. The coal dust generated by the coal flow and air flow has no passage and gap to diffuse outward, which can avoid dust overflow and harm the health of employees. It solves the problem that the traditional flat gates used in the existing mines inevitably have gaps due to the structure, which leads to the inevitable overflow of dust with the airflow. Passive blocking or timely cleaning only treats the symptoms but not the root cause. The dust overflow is very harmful, pollutes the air in the factory space, harms the health of employees at work, and the concentration after dust collection has the risk of combustion and explosion under certain conditions.

[0020] 2. The utility model provides a filter frame and a water jet pipe, and utilizes the filter cloth in the filter frame to filter the dust-containing airflow, thereby further preventing dust from overflowing. At the same time, the water jet pipe and the nozzle can flush water to the filter cloth for cleaning, thereby preventing dust or naked particles from accumulating and hindering the gate from sliding on the slideway. The gate can be cleaned with clean water regularly or irregularly, thereby solving the problem of traditional flat gates used in various mines. Since the flat gates used need to open and close in the idle section, dust will be brought out when the flat gates move, causing dust to overflow into the external environment. Dust overflow still exists, and it is difficult to handle the dust.

[0021] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] Specifically, an upper cover plate 1011 is installed on the top of the idle section frame 101, an adjustment groove 1012 is arranged at the lower part of the inner wall of one side of the idle section frame 101, a telescopic moving cylinder 104 is slidably connected to the upper part of the feed frame 102, a support 105 is slidably connected to the lower part of the discharge frame 103, a baffle 106 is fixedly connected to the bottom edge of the inner wall of the other side of the idle section frame 101, a limiting assembly 107 is arranged inside the adjustment groove 1012, and the limiting assembly 107 includes a limiting plate 1071 and a pull ring 1072 installed at the center position of its outer wall, and the inner wall of the limiting plate 1071 is slidably connected to the lower part of the discharge frame 103, and a baffle 106 is fixedly connected to the bottom edge of the inner wall of the other side of the idle section frame 101. Connecting rods 1073 are evenly spaced and fixedly connected from front to back, the other end of the connecting rod 1073 passes through the through hole on the outer wall of the adjusting groove 1012 and is connected to the clamping plate 1075, a spring 1074 is sleeved on the outer side of the outer wall of the connecting rod 1073, and the spring 1074 is located between the inner wall of the adjusting groove 1012 and the clamping plate 1075, and the outer front and rear ends of the upper surface of the gate plate 201 are rotatably connected with idle travel smooth track wheels 204, and an oil cylinder 205 is installed under the outer wall of the support plate 202, and one side of the outer wall of the oil cylinder 205 is fixedly connected to the outer wall of the gate body 1 through a square flange 206.

[0035] Furthermore, the idle section frame 101 is the movement range of the gate plate 201. The vertical slide wheel 203 can support and assist the sliding of the gate plate 201. The upper cover plate 1011 closes the top of the idle section frame 101. The telescopic cylinder 104 can telescopically slide in the feed frame 102. Similarly, the support 105 can also telescopically slide at the bottom of the discharge frame 103. The baffle 106 limits the bottom side of the filter frame 3. The limit plate 1071 and the clamping plate 1075 are connected by the connecting rod 1073 to play a connecting transmission role. The clamping plate 1075 is driven to move under the elastic performance of the spring 1074, and the clamping plate 1075 is used to limit the other side of the bottom of the filter frame 3. The idle smooth track wheel 204 limits and assists the sliding of the front and back of the gate plate 201. The square flange 206 installs and seals the oil cylinder 205.

[0036] The operation process of this embodiment is as follows: first, the gate body 1 is installed at the bottom of the scraper, and then the coal flow enters the gate body 1 through the telescopic cylinder 104 and the feed frame 102 above. When it is necessary to transport raw coal, the oil cylinder 205 is started at this time, and the telescopic end of the oil cylinder 205 contracts to drive the support plate 202 at the bottom of the gate plate 201 on one side to move, so that the support plate 202 slides under the auxiliary action of the vertical slide wheel 203, and the upper gate plate 201 is driven to move by the support plate 202, so that the gate plate 201 moves to the inside of the idle section frame 101 under the auxiliary action of the idle smooth track wheel 204, and the gate plate 201 under the feed frame 102 can be opened, and then the raw coal will be discharged through the discharge frame 103 and the support 105, and after the raw coal is discharged, it is The gate plate 201 is pushed to the initial position and closed by the oil cylinder 205, so the gate plate 201 can make reciprocating motion. At the same time, the gate plate 201 is in a fully enclosed space inside the gate body 1, which is a fully enclosed form that is not connected to the outside world. The oil cylinder 205 is installed on the outer wall of the gate body 1 through the square flange 206, wherein the square flange 206 is both a support seat and a closing cover for the oil cylinder 205. At the same time, only the cylinder rod of the oil cylinder 205 extends into the gate body 1 to act on the gate plate 201, and the slideways of the gate plate 201 are all designed inside the gate body 1. Therefore, the opening and closing movements of the gate plate 201 are all carried out in a sealed space without any connection with the outside. The coal powder dust generated by the coal flow and air flow has no passage or gap to diffuse outward. Specific embodiment 2

[0038] See also Figure 2 , 5 6. Based on the specific embodiment 1, what is different from the first embodiment is that: a filter frame 3 and a water jet pipe 4 are provided, which solves the problem that the traditional flat gates used in the existing mines need to open and close in the idle section, so that dust will be brought out when the flat gate moves, causing the dust to overflow into the external environment. Dust overflow still exists, and it is difficult to handle the dust.

[0039] Specifically, a filter cloth 301 is installed inside the filter frame 3, and a nozzle 401 is installed at the other end of the water jet pipe 4, and the nozzle 401 penetrates the outer wall of the idle section frame 101 and is placed inside thereof.

[0040] Furthermore, the specification of the filter cloth 301 is PM10, which can filter the coal powder and also rinse out the water vapor and coal slime through the filter cloth 301 . Water can be introduced through the water jet pipe 4 and the nozzle 401 to clean the filter cloth 301 .

[0041] The operation process of this embodiment is as follows: since the opening and closing movement process of the gate plate 201 is inside the sealed gate body 1, there is no passage or gap for diffusion outward, so that the coal powder dust generated by the coal flow and the air flow flows out from the opening and closing of the gate plate 201 to the idle section frame 101, and a filter frame 3 is installed at the bottom of the idle section frame 101, and a filter cloth 301 is installed inside the filter frame 3, wherein when the dust-containing gas passes through the filter cloth 301 inside the filter frame 3, the fresh air is naturally discharged, and the dust is filtered in the filter cloth 301, and the air is naturally diffused and discharged after being filtered, and the water vapor and coal sludge water are also rinsed out through the filter cloth 301, and then the cleaning water is introduced through the water jet pipe 4, and the cleaning water can be flushed and cleaned to the filter cloth 301 after being sprayed from the nozzle 401, so as to achieve the effect of cleaning the filter cloth 301, and prevent the accumulation of dust or naked particles from hindering the sliding of the gate plate 201 on the slide, and it can be cleaned with clean water regularly or irregularly, and at the same time, the pull puller is pulled outward. The pull ring 1072 is subjected to the force to drive the limit plate 1071 to move outward, and the inner wall of the limit plate 1071 is connected to the card plate 1075 through the connecting rod 1073. Therefore, when the limit plate 1071 moves, the card plate 1075 will be driven to move under the action of the connecting rod 1073 and squeeze the spring 1074. At this time, the card plate 1075 can be pulled into the interior of the adjusting groove 1012, and the limiting effect on the outer side of the bottom of the filter frame 3 can be cancelled. Then the filter frame 3 can be taken out, and the filter cloth 301 inside can be disassembled and replaced. When installing the filter frame 3, the inner end of the filter frame 3 is placed above the baffle 106, and then the force on the pull ring 1072 is stopped. At this time, the card plate 1075 is rebounded to the initial position under the action of the elastic performance of the spring 1074, and the other side of the bottom of the filter frame 3 is limited, which is convenient for the staff to disassemble and use, and the filtering efficiency and effect can be improved.
