Description

Technical Field

[0001] This utility model relates to the field of underground coal mine spray dust suppression technology, specifically to an antifreeze and anti-clogging spray dust suppression device. Background Technology

[0002] A spray dust suppression device is a device that uses a high-pressure pump to pressurize water, which is then sprayed through specially designed nozzles to form extremely fine water mist particles. These water mist particles collide with and adhere to dust particles in the air, causing the dust particles to become heavier and settle to the ground, thus achieving dust suppression. Its structure is very simple, consisting of a water atomization device organized by nozzles, pipes, a high-pressure pump, and a control system.

[0003] During daily production and use, especially under low-temperature conditions, due to the physical properties of water freezing, residual water stains can easily freeze and crack or block the pipes. In addition, the water quality in the ground workshop often does not meet the standard requirements, which can also cause the spray system to become clogged. Summary of the Invention

[0004] This invention addresses the technical problem of traditional spray dust suppression devices where residual water stains easily cause pipes to freeze and crack or become clogged at low temperatures, or where substandard water quality causes the spray system to become blocked. It provides an antifreeze and anti-clogging spray dust suppression device.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: an antifreeze and anti-clogging spray dust suppression device, including a four-way connecting pipe, the first interface of the four-way connecting pipe being connected to a nozzle assembly through a first pipeline; the second interface of the four-way connecting pipe being connected to a water tank through a second pipeline, and a drain valve being connected in series on the second pipeline; the third interface of the four-way connecting pipe being connected to the water tank through a third pipeline, and a water pump valve and a water pump being connected in series on the third pipeline; the fourth interface of the four-way connecting pipe being connected in series from near to far through a fourth pipeline, and an air pump valve, a heater, and a fan; the drain valve, water pump, fan, water pump valve, and air pump valve are all connected to a programmable interlock controller through control cables; a water purification and softening device is installed in the water tank.

[0006] Furthermore, the water purification and softening device is installed at the bottom of the water tank.

[0007] Compared with the prior art, the present invention has the following beneficial effects:

[0008] When the water pump switch is turned on, the water pump and water pump valve start, and the spray head sprays water; when the drain switch is turned on, the drain valve opens, and the pipeline directly discharges the water accumulated in the pipe into the water tank; when the air pump switch is turned on, the air pump, air pump valve, and heater start, and the air pump blows hot air to blow away and dry the residual water stains in the pipe. Moreover, the three functions are connected by a four-way pipe and interlocked with each other by a programmable controller. Only one function can be implemented at a time, which is practical and convenient. The overall structure is simple and easy to manufacture and promote. Attached Figure Description

Detailed Implementation

[0013] The present invention will be further described below with reference to specific embodiments. Example 1

[0014] like Figure 1 and 2 As shown, an antifreeze and anti-clogging spray dust suppression device includes a four-way connecting pipe 2. The first port of the four-way connecting pipe 2 is connected to a nozzle assembly 1 through a first pipeline. The second port of the four-way connecting pipe 2 is connected to a water tank 9 through a second pipeline, and a drain valve 3 is connected in series on the second pipeline. The third port of the four-way connecting pipe 2 is connected to the water tank 9 through a third pipeline, and a water pump valve 12 and a water pump 5 are connected in series on the third pipeline. The fourth port of the four-way connecting pipe 2 is connected in series with a wind pump valve 13, a heater 7, and a fan 6 from near to far through a fourth pipeline. All connections are firmly fixed. The drain valve 3, water pump 5, fan 6, water pump valve 12, and wind pump valve 13 are all connected to a programmable interlock controller 11 through control cables 8. A water purification and softening device 10 is installed in the water tank 9.

[0015] Furthermore, the water purification and softening device 10 is installed at the bottom of the water tank 9. The water purification and softening device 10 has the functions of purifying and softening water and can be purchased directly.

[0016] The power of the fan 6 and water pump 5 is sufficient to meet the requirements for water intake and drainage within the pipeline length.

[0017] Working principle and method:

[0018] In use, the programmable interlock controller 11 starts the water pump 5 and opens the water pump valve 12, while simultaneously interlocking and closing the drain valve 3 and the air pump valve 13. After the water pump starts, the water purified and softened by the water purification and softening device 10 is discharged to the nozzle group 1 for spray dust suppression. After the dust suppression work is completed, the programmable interlock controller 11 opens the drain valve 3 and simultaneously interlocks and closes the water pump 5, water pump valve 12, and air pump valve 13. The water remaining in the pipeline 4 and nozzle group 1 flows back to the water tank 9 by gravity. After the water flow is completed, the programmable interlock controller 11 starts the fan 6 and opens the air pump valve 13 and the heater 7, while simultaneously interlocking and closing the drain valve 3 and the water pump valve 12. The fan 6 blows the hot air heated by the heater 7 into the pipeline 4 to blow away and dry the residual water stains. This avoids the phenomenon of residual water stains freezing and cracking the pipeline in low temperature environment, reducing the safety risks during use. The overall structure is simple, easy to manufacture and promote.

[0019] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
