Description

Technical Field

[0001] The invention relates to the technical field of chute scraper transfer machines for fully mechanized working faces in underground coal mines, in particular to a mine chute coal-water separation device and a chute scraper transfer machine. Background Art

[0002] In the fully-mechanized mining face of coal mines, the scraper conveyor is a chute conveying and transferring equipment used in conjunction with the fully-mechanized mining face equipment. It completes the task of conveying and transferring the coal sent by the working face conveyor to the belt conveyor. It is one of the main equipment of the fully-mechanized mining face. Some fully-mechanized mining faces of coal mines have a large amount of water inflow, and the working face is uneven. A large amount of water gushes out during the coal mining process. When the working face is in a downward mining, the water will be unloaded into the conveyor in the chute together with the scraper conveyor, and then transferred and unloaded to the belt conveyor. When the belt conveyor climbs at a large angle, the coal and water in the belt conveyor slip and are difficult to be taken away. A large amount of coal and water gathered in the low-lying area before climbing will overflow from the belt conveyor. This problem brings great trouble to the mine. At present, the mine can only use a water pump to pump out the water on the working face. This method requires shutdown to be carried out, which is not only time-consuming and labor-intensive, but also affects the efficiency of coal mining. At the same time, when coal mining is carried out again, a large amount of water will be brought into the conveyor and unloaded onto the belt conveyor. The problem of too much water on the belt conveyor is difficult to solve completely. Summary of the invention

[0003] In view of this, the purpose of the present invention is to provide a coal-water separation device for a mine chute, which is arranged in the climbing section or bridge section of the scraper loader of the chute, and can separate the water in the chute of the loader and collect it for centralized treatment. The device has a significant effect of coal-water separation, and is easy to install and maintain, which solves a major problem for the mine.

[0004] Another object of the present invention is to provide a chute scraper transfer machine, which is equipped with a mining chute coal-water separation device, which can separate the water in the transfer machine chute to prevent water from entering the belt conveyor and reduce the belt conveyor's failure and shutdown rate caused by large amounts of water.

[0019] The specific embodiments of the present invention are described in detail below with reference to the accompanying drawings:

[0020] like Figure 1 , 2 As shown in Figures 3 and 4, a coal-water separation device for a mining chute of the present invention comprises a drainage middle trough 1, a coal-water collecting device 2 and a hook 3. The drainage middle trough 1 is connected to the coal-water collecting device 2 through the hook 3, and the coal-water collecting device 2 is suspended below the drainage middle trough 1. The hook 3 is welded to the bottom plate 12 of the drainage middle trough 1. The drainage middle trough 1 is welded by a middle plate 11, a bottom plate 12, a side plate, a connecting plate, etc., and has the same structure as the ordinary middle trough of the transfer machine, with consistent interfaces at both ends, and can be installed interchangeably. The difference is that the middle plate 11 and the bottom plate 12 of the drainage middle trough 1 are both provided with 18 25mm*300mm oblong holes, and the oblong holes on both sides are arranged at 20° to the horizontal direction, and the middle oblong hole is arranged horizontally. Such an arrangement can avoid the chain path, does not affect the strength of the middle plate 11 and the bottom plate 12, and can maximize the water flow area, so that the water in the transfer machine trough can be fully discharged. The coal-water collecting device 2 is welded into a funnel shape by two side panels A27, two side panels B28 and a bottom panel A25; four lifting rings 21 are symmetrically arranged on the upper outer side of the coal-water collecting device 2, and the lifting rings 21 are welded and fixed to the side panels A27 and B28.

[0021] In addition, if Figure 3 As shown, a filter screen 26 is arranged horizontally inside the coal-water collection device 2, and the periphery of the filter screen 26 is welded and fixed to the side plate A27 and the side plate B28. The filter screen 26 can filter the coal slime discharged together with the water. A coal cleaning port C is opened in the middle of the side plate A27 and is located above the filter screen 26. Four threaded holes are opened around the coal cleaning port C, and the cover plate 22 is connected by bolts to cover the coal cleaning port C. When there is a lot of coal slime on the filter screen, the cover plate 22 can be opened to clean the accumulated coal slime from the coal cleaning port C. Two hydraulic pipe quick-connect connectors 23 are arranged below the coal-water collection device 2, and the quick-connect connectors 23 are welded and fixed to the side plate A27. When there is a lot of coal slime below the filter screen 26, a high-pressure water pipe can be connected for flushing.

[0022] Furthermore, a water pipe joint 24 is arranged at the bottom of the coal-water collection device 2; a round hole is opened in the bottom plate A25, and the water pipe joint 24 is inserted into the round hole and welded to the bottom plate A25. The water pipe joint 24 can be connected to a water pipe to lead the discharged water to a low-lying area for centralized wastewater treatment.

[0023] The embodiment of the present invention also provides a chute scraper transfer machine, which is provided with the mine chute coal-water separation device described in the above embodiment. Since the scraper transfer machine includes the above mine chute coal-water separation device, it also has the above technical effects, which will not be described in detail.
