Description

Technical Field

[0001] This utility model relates to the field of dust suppression technology in mining areas, and more particularly to a dust suppression device for mining areas. Background Technology

[0002] In the daily operations of a mine, the mining, transportation, and crushing of ore generate a large amount of dust. This dust not only poses a serious threat to the health of mine workers, and long-term inhalation may lead to occupational diseases such as pneumoconiosis, but also affects the mine's production environment, reduces the service life of equipment, and even poses a safety hazard of dust explosion. Therefore, efficient dust suppression methods have become a key issue that needs to be addressed in mine operations, and spray dust suppression devices have emerged to meet this need.

[0003] However, existing mine spray dust suppression devices have many drawbacks. On the one hand, the devices are usually bulky, which makes them extremely difficult to maneuver in the complex terrain and narrow passages of the mine. The internal environment of the mine is already complex, and large equipment is difficult to move flexibly to various areas that need dust suppression, which greatly limits its scope of use and dust suppression effect. On the other hand, many spray dust suppression devices rely on wind power to drive the water mist to spray out. This method makes it difficult to accurately control the range of water mist. When the wind is unstable or the wind direction is changeable, the water mist may be blown to areas that do not need dust suppression, or even cause secondary pollution problems such as dampness of materials, affecting the quality of mineral products and causing additional economic losses to the mine. Utility Model Content

[0004] In order to overcome the problems of existing mine spray dust suppression devices, which are usually large in size and have poor maneuverability, and whose water mist spraying is driven by wind and whose effective range is not adjustable, easily causing secondary pollution, this utility model provides a mine spray dust suppression device.

[0005] The technical solution is as follows: a dust suppression spray device for the mine, including a water pump, a dust suppression spray assembly, a water tank assembly, a trolley assembly, and an electrically controlled valve; the front and rear ends of the water pump are respectively equipped with a dust suppression spray assembly and a water tank assembly; the water tank assembly and the lower end of the water pump are equipped with a trolley assembly; the water tank assembly includes a water storage tank, a tank sealing cap, and a mechanical valve; the trolley assembly includes a transport vehicle and a push-pull handle; the dust suppression spray assembly includes a connecting rod, a square water pipe, a clamping and tightening knob, and an atomizing nozzle.

[0009] Furthermore, a connecting rod is installed in front of the water pump and is fixedly connected to the transport vehicle; a square water pipe is vertically inserted through the front end of the connecting rod and is connected to the output end of the water pump via a flexible hose; a clamping tension knob is installed at the front end of the connecting rod, and the clamping tension knob is threadedly connected to the outer shell of the connecting rod for adjustment, and when the threaded rod of the clamping tension knob is adjusted backward, it squeezes and clamps the square water pipe in place; an atomizing nozzle is installed at the lower end of the square water pipe and is connected to the square water pipe.

[0010] Furthermore, it also includes a tensioning knob lifting sleeve, an angle adjustment knob, and a baffle; a tensioning knob lifting sleeve is provided below the tensioning knob, and the sleeve of the tensioning knob lifting sleeve is vertically raised and lowered along the square water pipe and clamped and fixed by the locking knob at its front end.

[0012] The beneficial effects are: This utility model realizes the dynamic adjustment of the working power of the water pump by holding the electric control valve, thereby realizing the dynamic adjustment function of the spray volume;

[0013] The miniaturized transportation function of the spraying equipment is realized by using a trolley component, which greatly optimizes the problem of poor passability of dust suppression equipment in narrow spaces such as mines;

[0014] The water inside the storage tank is pressurized by a water pump and sprayed out from the atomizing nozzle, thereby effectively improving the power of water atomization and dust suppression. Compared with traditional wind-powered spray dust suppression, this utility model has a greater spray force and a wider range of action.

[0015] By adjusting the clamping tension knob and connecting rod, the square water pipe can be vertically moved along the movable groove of the connecting rod, thereby adjusting the height of the atomizing nozzle.

[0028] A connecting rod 401 is provided in front of the water pump 1, and the connecting rod 401 is fixedly connected to the transport vehicle 301; a square water pipe 402 is vertically inserted through the front end of the connecting rod 401, and the square water pipe 402 is connected to the output end of the water pump 1 through a hose; a clamping tension knob 403 is provided at the front end of the connecting rod 401, and the clamping tension knob 403 is threadedly connected to the outer shell of the connecting rod 401 for adjustment, and when the threaded rod of the clamping tension knob 403 is adjusted backward, the square water pipe 402 is squeezed and clamped in place; an atomizing nozzle 407 is provided at the lower end of the square water pipe 402, and the atomizing nozzle 407 is connected to the square water pipe 402.
