Description

Technical Field

[0001] The utility model belongs to the technical field of dust suppression devices for coal mines, in particular to a spray dust suppression device for a hydraulic support of a fully mechanized mining working face. Background Art

[0002] Coal is currently one of the main energy sources in my country, but due to the complex working conditions and poor working environment of coal mines, safety accidents often occur, causing significant losses to society and families. The fully mechanized mining face is the main source of dust generation and will definitely be the focus of dust prevention and control. However, the water pipes connected to the nozzles of some existing dust suppression devices are made of inflexible materials. Inflexible water pipes may be difficult to adapt to the complex spatial environment of the working face due to lack of flexibility during installation, such as the movement of equipment or the irregular shape of the coal wall, thereby affecting the coverage and effect of the spray. Hard pipes may take up more space, which may become a problem in a small working environment, limiting the space for workers to move. At the same time, the water tanks of some existing devices are usually a relatively sealed mechanism, making the device difficult to clean. The difficulty in cleaning the inside of the box may lead to accumulated dirt and microbial growth. Accumulated impurities may cause nozzle blockage or other failures of the spray system, increasing the maintenance frequency and cost of the system.

[0003] In the publication number CN 215927450 U, a hydraulic support spray dust suppression device for a comprehensive mining working face is disclosed, comprising: a water supply tank; an adjustment component, the bottom of the adjustment component is fixed to the top of the water supply tank, the adjustment component comprises a vertical rod, one side of the vertical rod is fixedly connected to a third movable seat, one side of the third movable seat is movably connected to a connecting plate through a pin, and one side of the connecting plate is fixedly connected to a fixed water pipe component. The hydraulic support spray dust suppression device for a comprehensive mining working face provided by the utility model can conveniently and effectively adjust the angle of the dust suppression nozzle by setting the adjustment component, conveniently expand the dust settling area, and facilitate the operation of the staff, and the water pipe and the fixed plate are detachably connected, which can facilitate the staff to remove the dust suppression nozzle, so as to adapt to different use environments and facilitate the use of the staff.

[0004] However, the water supply tank of the above device is a relatively sealed structure, so the water supply tank cannot be opened, and it becomes very difficult to clean and maintain the water supply tank, which causes the water in the water tank to stagnate for a long time, increases the accumulation of bacteria and other pollutants, and thus reduces the water quality. In addition, additional tools or equipment are required to assist drainage, which adds additional costs and labor intensity. At the same time, the water pipe connecting the device and the dust suppression nozzle is an inflexible hard pipe, which may be difficult to adapt to the complex spatial environment of the working face due to lack of flexibility during installation. Due to the inflexibility, this water pipe may not be able to adapt well to changes in the working face, such as the movement of equipment or the irregular shape of the coal wall, thereby affecting the coverage and effect of the spray. Therefore, in order to solve the above problems, a spray dust suppression device for a hydraulic support of a comprehensive mining working face is proposed. Utility Model Content

[0005] The technical problem solved by the utility model is to provide a hydraulic support spray dust reduction device for a comprehensive mining working face which has high practicability, simple operation and relatively simple structure.

[0006] In order to solve the above technical problems, the utility model provides a hydraulic support spray dust suppression device for a comprehensive mining working face, comprising: a water tank fixed above a base plate, the top cover of the water tank is connected to a box cover, a water outlet is opened at the bottom of the side wall of the water tank, a water pump is abutted on the box cover, a water inlet pipe is installed at the bottom of the water pump, the water inlet pipe is inserted into the water tank, a water outlet pipe is installed on the left side of the water pump, and a nozzle assembly is threadedly connected to the water outlet pipe, the water pump and the nozzle assembly are threadedly connected through the water outlet pipe, and a fixing mechanism for the nozzle assembly is fixed on the top of the box cover away from the water pump.

[0007] As a further solution of the utility model, the bottom of the inner wall of the water tank is lower near the water outlet, and the water outlet is communicated with the inner cavity of the water tank, which can more effectively guide the water flow to the lowest side of the water tank, ensuring that the water can be fully used for spray dust reduction.

[0008] As a further solution of the utility model, the water tank upper cover is connected to two sets of tank covers, and the openable tank covers allow staff to easily clean and maintain the inside of the water tank.

[0009] As a further solution of the utility model, the water pump is placed on a box cover at a side away from the water outlet, and a groove matching the water inlet pipe is provided on the box cover.

[0010] As a further solution of the utility model, the nozzle assembly includes a mounting block, a soft water pipe and a dust suppression nozzle. The mounting block is a concave cylindrical column, and threads are evenly distributed on the outside of the water outlet pipe. A threaded groove matching the water outlet pipe is provided on the mounting block.

[0011] As a further solution of the utility model, the soft water pipe is made of soft and bendable material, and one side of the soft water pipe is connected to the dust suppression nozzle, and the other side is connected to the mounting block. It can be bent and adjusted according to the actual needs of the working surface to adapt to different spaces and angles.

[0015] 1. The utility model connects the water pump and the dust reduction component through a flexible water pipe. The soft and bendable water pipe can be bent and adjusted according to the actual needs of the working surface to adapt to different spaces and angles, ensuring that the spray can cover more areas. The soft water pipe is easier to install and wire, reducing the difficulty and time of installation. Since the soft water pipe can more conveniently adjust the spray direction and range, it can more effectively aim at the dust generating point and improve the dust reduction efficiency.

[0016] 2. The utility model is provided with an openable box cover and a water outlet on the water tank. The openable box cover allows the staff to easily clean and maintain the inside of the water tank, which helps to keep the water quality clean and extend the service life of the equipment. The inclined design of the bottom of the water tank can more effectively guide the water flow to converge, reduce water waste, and ensure that the water can be fully used for spray dust reduction. The opened water outlet is convenient for discharging the water inside the tank to reduce maintenance time and reduce water waste during cleaning and maintenance, thereby saving costs.
