Abstract
Description
Technical Field
[0001] This utility model relates to the field of water spraying and dust suppression technology, and in particular to a wireless automatic water spraying and dust suppression device for underground mines with automatic backwashing function. Background Technology
[0002] Dust pollution is a significant threat to the working environment and personnel health during underground mining operations. Therefore, efficient water spraying dust suppression devices have become crucial equipment for ensuring safe production. With the advancement of intelligent mine construction, water spraying dust suppression devices with wireless automatic control functions are gradually being widely used. However, the impact of impurities in the water on the device cannot be ignored. Therefore, the development of a wireless automatic water spraying dust suppression device for underground mining that can automatically backwash is urgently needed.
[0003] Existing underground dust suppression water spraying systems in mines mostly employ simple mechanical structures and control methods. They primarily use water pumps to extract water from storage tanks, which is then transported via pipelines to nozzles installed in the roadways to suppress dust by spraying water mist. The nozzles are mostly fixed in design, and the operation of the system relies mainly on manual control for starting and stopping, or on setting the spraying cycle using simple time relays. Water circulation is maintained by gravity or pump pressure. The overall technical principle focuses on water delivery and spraying, lacking effective design for water purification and nozzle maintenance.
[0004] However, since existing devices generally lack backwashing filtration structures, impurities such as mud, sand, and slag mixed in the water cannot be effectively filtered out. After long-term use, these impurities easily accumulate inside the nozzles, causing them to clog. Once the nozzles are clogged, not only will the spray range shrink and the atomization effect deteriorate, resulting in a significant reduction in dust suppression efficiency, but frequent nozzle replacements will also increase equipment maintenance costs, seriously affecting the normal operation and stability of the wireless automatic water sprinkler dust suppression device in mines. Therefore, a wireless automatic water sprinkler dust suppression device with automatic backwashing function in mines is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a wireless automatic water spraying and dust suppression device for underground mines with an automatic backwashing function. It aims to improve the problem that the existing technology does not have a backwash filter cylinder, which makes it impossible for the device to effectively remove impurities from the water, resulting in nozzle blockage and affecting the spraying effect.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A wireless automatic water spraying and dust suppression device for underground mining with automatic backwashing function includes a connecting cabinet. A rotating door is rotatably connected to the side wall of the connecting cabinet. A first connecting pipe is fixedly connected inside the connecting cabinet. A second water pump is fixedly connected to one end of the first connecting pipe. A filter cylinder is fixedly connected inside the connecting cabinet. A connecting component is provided on the outer wall of the filter cylinder. A fixing frame is fixedly connected to the side wall of the connecting cabinet. A backwashing component is provided on the side wall of the fixing frame. A water suction component is provided inside the connecting cabinet.
[0008] The backflushing assembly includes an air compressor, the outer wall of which is fixedly connected to the side wall of the mounting frame. A second connecting pipe is fixedly connected to the output end of the air compressor. One end of the second connecting pipe is fixedly connected to the top of the filter cartridge. A drain pipe is fixedly connected to the bottom of the filter cartridge. A third electric valve is fixedly connected to one end of the drain pipe.
[0009] As a further description of the above technical solution:
[0010] The connecting assembly includes a third connecting pipe, one end of which is fixedly connected to the outer wall of the filter cartridge, and a first electric valve and a second electric valve are fixedly connected inside the third connecting pipe.
[0011] As a further description of the above technical solution:
[0012] The water absorption assembly includes a water supply pipe, the outer wall of which is fixedly connected to the inside of the connecting cabinet, a first water pump is fixedly connected to one end of the water supply pipe, and the other end of the water supply pipe is fixedly connected to the outer wall of the third connecting pipe.
[0013] As a further description of the above technical solution:
[0014] A first hollow column is fixedly connected to the outer wall of the first connecting pipe, and a first clamping plate is fixedly connected to the outer wall of the first hollow column.
[0015] As a further description of the above technical solution:
[0016] The first card plate has a second card block that is slidably connected inside, and the side wall of the second card block is fixedly connected to a second hollow column.
[0017] As a further description of the above technical solution:
[0018] The bottom of the second hollow column is fixedly connected to an atomizing nozzle, and the top of the atomizing nozzle is fixedly connected to the bottom of the second hollow column.
[0019] As a further description of the above technical solution:
[0020] The outer wall of the second hollow column is fixedly connected to the side wall of the second card block, and the outer wall of the second hollow column is fixedly connected to the second card plate.
[0021] As a further description of the above technical solution:
[0022] The second card plate has a first card block slidably connected to its side wall, and the side wall of the first card block is fixedly connected to the outer wall of the first hollow column.
[0023] This utility model has the following beneficial effects:
[0024] 1. In this utility model, gas is generated by an air compressor and connected through a second connecting pipe, which lifts and pushes the filter cylinder into the interior, achieving the effect of backflushing the filter cylinder. This solves the problem that without a backflushing filter cylinder, the device cannot effectively remove impurities from the water, causing nozzle blockage and affecting the spraying effect, thus improving the stability of the wireless automatic water spraying dust suppression device for underground mining.
[0025] 2. In this utility model, rotating the atomizing nozzle drives the second hollow column to rotate. The second hollow column, under force, drives the second clamping plate on its outer wall to rotate, causing its inner wall to detach from the side wall of the first clamping block. At the same time, during the rotation of the second hollow column, the side wall of the second clamping block also detaches from the side wall of the second hollow column, achieving the effect of quickly disassembling the atomizing nozzle. This solves the problem that the inability to quickly disassemble the nozzle would prolong maintenance time and affect the normal use of the device, thus improving the convenience of the wireless automatic water spraying dust suppression device for underground mining.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0036] Reference Figures 1-5 An embodiment of this utility model provides a wireless automatic water spraying and dust suppression device for underground mines with automatic backwashing function, including a connecting cabinet 2, a rotating door 5 rotatably connected to the side wall of the connecting cabinet 2, a first connecting pipe 1 fixedly connected inside the connecting cabinet 2, a second water pump 6 fixedly connected to one end of the first connecting pipe 1, a filter cylinder 10 fixedly connected inside the connecting cabinet 2, a connecting component provided on the outer wall of the filter cylinder 10, a fixing frame 8 fixedly connected to the side wall of the connecting cabinet 2, a backwashing component provided on the side wall of the fixing frame 8, and a water suction component provided inside the connecting cabinet 2.
[0037] The backwash assembly includes an air compressor 7, which generates high-pressure gas. This gas, along with a second connecting pipe 9, is injected into the top of the filter cartridge 10, achieving a reverse flushing effect to remove impurities from the filter cartridge and solving the problem of incomplete cleaning with traditional water backwashing. The outer wall of the air compressor 7 is fixedly connected to the side wall of the mounting bracket 8. The output end of the air compressor 7 is fixedly connected to the second connecting pipe 9, one end of which is fixedly connected to the top of the filter cartridge 10. The filter cartridge 10 uses a sintered stainless steel filter screen to intercept solid particles ≥50μm, preventing nozzle clogging. This is a standard design for mining filtration and will not be elaborated further. A drain pipe 14 is fixedly connected to the bottom of the filter cartridge 10, one end of which is fixedly connected to… There is a third electric valve 15, and the connecting assembly includes a third connecting pipe 11. One end of the third connecting pipe 11 is fixedly connected to the outer wall of the filter cartridge 10. The first electric valve 12 and the second electric valve 13 are fixedly connected inside the third connecting pipe 11. The first electric valve 12 and the second electric valve 13 are used to control the opening and closing of the third connecting pipe 11. Together with the third electric valve 15, they realize the isolation of water inlet and the switching of sewage discharge channels during backwashing, ensuring zero-interruption dust reduction operation during the backwashing process. The water suction assembly includes a water supply pipe 3. The outer wall of the water supply pipe 3 is fixedly connected to the inside of the connecting cabinet 2. One end of the water supply pipe 3 is fixedly connected to a first water pump 4, and the other end of the water supply pipe 3 is fixedly connected to the outer wall of the third connecting pipe 11.
[0038] Reference Figures 1-6 and Figure 7 A first hollow column 16 is fixedly connected to the outer wall of the first connecting pipe 1. A first locking plate 18 is fixedly connected to the outer wall of the first hollow column 16. The first locking plate 18 is used to limit the second locking block 22. It works in conjunction with the wedge structure of the second locking plate 21 and the first locking block 17 to rotate and lock / unlock, achieving the effect of quickly disassembling the atomizing nozzle 20. The second locking block 22 is slidably connected inside the first locking plate 18. A second hollow column 19 is fixedly connected to the side wall of the second locking block 22. The second hollow column 19 is used to transmit rotational force and link the atomizing nozzle. The head 20 moves synchronously with the card plate assembly, enabling the nozzle assembly to be quickly separated as a whole, reducing maintenance time and costs. The bottom of the second hollow column 19 is fixedly connected to the atomizing nozzle 20, and the top of the atomizing nozzle 20 is fixedly connected to the bottom of the second hollow column 19. The outer wall of the second hollow column 19 is fixedly connected to the side wall of the second card block 22. The outer wall of the second hollow column 19 is fixedly connected to the second card plate 21. The side wall of the second card plate 21 is slidably connected to the first card block 17, and the side wall of the first card block 17 is fixedly connected to the outer wall of the first hollow column 16.
[0039] Working principle: When using the mine wireless automatic water spraying dust suppression device with automatic backwashing function, when the filter cylinder 10 is blocked, causing abnormal water pressure or when the timer setting is set, the system starts the backwash component, closes the second electric valve 13 to block the water inlet, and opens the first electric valve 12 and the third electric valve 15. The air compressor 7 generates high-pressure gas, which is injected into the top of the filter cylinder 10 through the second connecting pipe 9. The gas pushes the water flow to backwash the filter cylinder 10, and carries the impurities out through the third electric valve 15 of the drain pipe 14. After the backwashing is completed, the first electric valve 12 and the third electric valve 15 are reset, and the system continues to supply water normally.
[0040] Next, when disassembling the atomizing nozzle 20, first rotate the atomizing nozzle 20 to drive the second hollow column 19 to rotate. Then, under force, the second retaining plate 21 on the outer wall is disengaged from the side wall of the first retaining block 17. At the same time, during the rotation of the second hollow column 19, the second retaining block 22 is simultaneously slid out of the first retaining plate 18, so as to achieve rapid separation of the nozzle.
[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
