Description

Technical Field

[0001] This utility model relates to the field of auxiliary dust suppression technology for coal conveying equipment, specifically a spray dust suppression mechanism for coal conveyors. Background Technology

[0002] Coal conveyors are commonly used equipment in the mining, transportation, and processing of coal. However, during the transportation process, due to the small size and dryness of coal particles, a large amount of dust is easily generated. This dust not only pollutes the working environment and seriously harms the health of operators, but may also cause safety accidents such as explosions. In order to improve this situation, it is particularly important to develop a spray dust suppression mechanism for coal conveyors.

[0003] A dust suppression device for belt conveyors, as described in reference announcement number CN206886282U, includes a humidity sensor, a coal dust concentration sensor, a spraying device, and a main controller. The humidity sensor detects the humidity of the coal, and the coal dust concentration sensor, located at the transfer point of the belt conveyor, detects the coal dust concentration. The main controller is connected to the humidity sensor, the coal dust concentration sensor, and the spraying device. When the humidity detected by the humidity sensor is lower than a preset humidity threshold, and the coal dust concentration detected by the coal dust concentration sensor is higher than a preset concentration threshold, the main controller controls the spraying device to spray at the transfer point. Because the coal has a high humidity, a large amount of coal dust will not be generated during transfer, and dust removal operations can be omitted to avoid spraying too much water mist, which could lead to a high moisture content in the coal. Furthermore, this avoids resource waste. As can be seen from the above, although this device can be applied effectively, it is generally not easy to distribute evenly above the coal conveyor, thus making it difficult to fully cover the coal conveyor. This limits the dust suppression range of the device on the coal conveyor, affecting its dust suppression effect, and further improvements are needed. Utility Model Content

[0004] The purpose of this invention is to provide a spray dust suppression mechanism for coal conveyors, in order to solve the problem that although the device proposed in the background art can be applied well, it is usually not easy to distribute evenly in the upper area of ​​the coal conveyor, and thus it is not easy to fully cover the coal conveyor. This limits the spray dust suppression range of the device on the coal conveyor, thus affecting its dust suppression effect.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a spray dust suppression mechanism for a coal conveyor, comprising a top frame, with legs installed at the corners of the bottom of the top frame, water tanks installed on the bottom of the top frame inside several of the legs, a support frame installed at the center of the bottom of the water tanks, strip-shaped pipe seats on both sides of the bottom of the support frame, several valve pipes at the bottom of the strip-shaped pipe seats, and atomizing nozzles installed at the bottom of each valve pipe, and component racks installed on the outer walls of both sides of the support frame, with a water pump installed inside the component racks, one end of the water pump connected to the bottom of the water tank via a conduit, and the other end of the water pump connected to the top of the strip-shaped pipe seats via a conduit.

[0006] Preferably, a transparent observation window is provided at the center of the top of the water tank, and a level gauge is installed on the inner wall of one side of the water tank to monitor the water level inside the tank.

[0007] Preferably, a liquid injection port is provided on one side of the outer wall at the upper end of the water tank, and one end of the liquid injection port extends into the interior of the water tank. The liquid injection port is provided so that water can be injected into the interior of the water tank.

[0008] Preferably, a U-shaped frame is installed on the outer wall of one side of the valve pipe, and a bearing seat is bolted to the outer wall of the U-shaped frame. The bearing seat is provided to allow for the movable placement of the rotating shaft.

[0009] Preferably, a positioning frame is provided on the outer wall of the valve pipe on one side of the U-shaped frame, and a telescopic cylinder is movably installed on the outer wall of the positioning frame. A valve handle is rotatably installed at the end of the telescopic cylinder away from the positioning frame. The telescopic cylinder is designed to drive one end of the valve handle to move.

[0010] Preferably, a rotating shaft is rotatably mounted on one side inside the valve tube. One end of the rotating shaft passes through a bearing seat and is connected to one end of the valve handle. A circular baffle is installed on the outer wall of the rotating shaft. The outer wall of the circular baffle contacts the inner wall of the valve tube. The opening and closing size of the valve tube can be adjusted by setting the circular baffle.

[0011] Compared with the prior art, the beneficial effects of this utility model are: the spray dust suppression mechanism for coal conveyors not only expands the spray range to improve the dust suppression effect when the spray dust suppression mechanism is used, but also flexibly controls the spray volume of the atomizing nozzle, reducing the waste of water resources, while ensuring a good dust suppression effect, and also reducing the phenomenon of the spray dust suppression mechanism stopping operation due to the depletion of water in the water tank.

[0012] (1) The top frame is stably supported by several outriggers. The outriggers are placed on both sides of the coal conveyor so that the strip pipe seat under the top frame is above the coal conveyor. Because the strip pipe seat is designed in a long strip shape and several atomizing nozzles are evenly spaced at the bottom of the strip pipe seat, it can achieve full coverage spraying of the coal conveyor belt, effectively expanding the spraying range and thus improving the dust suppression effect when the spray dust suppression mechanism is used.

[0013] (2) By setting a valve pipe between each atomizing nozzle and the strip pipe seat, and setting a circular baffle and other adjustment components on the inner side of the valve pipe, the water flow in the corresponding valve pipe can be adjusted according to the dust concentration in different areas of the coal conveyor, so as to flexibly control the spray volume of the atomizing nozzle, reduce the waste of water resources, and ensure a good dust suppression effect.

[0014] (3) By setting a level gauge, the remaining water level inside the water tank is monitored. This data is transmitted to the control terminal of the conveyor for personnel to observe. Since a transparent observation window is set on the top of the water tank, personnel can also directly observe the water level inside the water tank through the transparent observation window, so that personnel can replenish the water inside the water tank in a timely manner, thereby reducing the phenomenon that the spray dust suppression mechanism stops operating due to the depletion of water inside the water tank.

[0023] When in use, the level gauge 18 is set to monitor the water level inside the water tank 3;

[0024] A liquid injection port 19 is provided on one side of the outer wall of the upper end of the water tank 3, and one end of the liquid injection port 19 extends into the interior of the water tank 3;

[0025] When in use, water is injected into the water tank 3 through the injection port 19;

[0026] A support frame 8 is installed at the center of the bottom of the water tank 3. A strip pipe seat 5 is provided on both sides of the bottom of the support frame 8. Several valve pipes 9 are provided at the bottom of the strip pipe seat 5. A U-shaped frame 14 is installed on the outer wall of one side of the valve pipe 9. A bearing seat 15 is bolted to the outer wall of the U-shaped frame 14.

[0027] In use, the bearing housing 15 is provided to allow for the movable placement of the rotating shaft 16;

[0028] A positioning frame 11 is provided on the outer wall of the valve pipe 9 on one side of the U-shaped frame 14. A telescopic cylinder 12 is movably installed on the outer wall of the positioning frame 11. A valve handle 13 is rotatably installed on the end of the telescopic cylinder 12 away from the positioning frame 11.

[0029] In use, the telescopic cylinder 12 is used to drive one end of the valve handle 13 to move.

[0030] A rotating shaft 16 is rotatably mounted on one side inside the valve tube 9. One end of the rotating shaft 16 passes through the bearing seat 15 and is connected to one end of the valve handle 13. A circular baffle 17 is installed on the outer wall of the rotating shaft 16, and the outer wall of the circular baffle 17 contacts the inner wall of the valve tube 9.

[0031] In use, the opening and closing size of the valve tube 9 can be adjusted by setting the circular baffle 17;

[0032] Atomizing nozzles 10 are installed at the bottom of valve pipes 9. Parts racks 6 are installed on the outer walls of both sides of the support frame 8. A water pump 7 is installed on the inner side of the parts rack 6. One end of the water pump 7 is connected to the bottom of the water tank 3 through a conduit, and the other end of the water pump 7 is connected to the top of the strip pipe seat 5 through a conduit.

[0033] In this embodiment, the dust suppression spray mechanism is first electrically connected to the control terminal of the coal conveyor, allowing the terminal to operate the mechanism. Several support legs 2 provide stable support to the top frame 1, which is positioned on both sides of the coal conveyor. This positions the strip-shaped pipe seat 5 below the top frame 1 above the conveyor. Because the strip-shaped pipe seat 5 is elongated and has several atomizing nozzles 10 evenly spaced at its bottom, it can achieve comprehensive spray coverage of the conveyor belt, thus expanding the spray range and improving the dust suppression effect on the coal conveyor. Furthermore, valve pipes 9 are installed between the atomizing nozzles 10 and the strip-shaped pipe seat 5, each equipped with a circular baffle 17 and other adjusting components. These valve pipes allow for adjustment of the water flow rate within the corresponding valve pipe 9 based on the dust concentration in different areas of the coal conveyor, flexibly controlling the atomizing nozzles 10. To reduce water waste, the spray volume is increased. Specifically, the telescopic cylinder 12 is activated to drive the valve handle 13 to move slightly, causing the valve handle 13 to drive the rotating shaft 16 to rotate. This causes the rotating shaft 16 to rotate the circular baffle 17 inside the valve pipe 9. The rotation range of the circular baffle 17 is ninety degrees to adjust the opening and closing of the valve pipe 9 and control the flow rate of the water source inside the valve pipe 9. Finally, the level gauge 18 is set to monitor the remaining water level inside the water tank 3. This data is transmitted to the control terminal of the conveyor for personnel to observe. Because the top of the water tank 3 is equipped with a transparent observation window 4, personnel can also directly observe the water level inside the water tank 3 through the transparent observation window 4. This makes it easy for personnel to promptly detect when the remaining water in the water tank 3 is insufficient and to replenish the water in the water tank 3. This effectively reduces the phenomenon of water depletion inside the water tank 3, thus completing the use of the spray dust suppression mechanism.
