Description

Technical Field

[0001] The utility model relates to a cooperative auxiliary device for underground mining in coal mines. Background Art

[0002] After the coal ore is mined, it needs to be transported from the mine to the ground through a conveyor.

[0003] In traditional technology, spray pipes are installed on both sides of the conveyor, and atomized water vapor is sprayed through the spray pipes to act on the surface of the coal ore, thereby reducing the dust generated during the transportation of the coal ore.

[0004] In actual operation, we found that this one-way spraying resulted in about 30% of the water mist being sprayed on both sides of the conveyor, causing waste. At the same time, this type of spray pipe without an external protective structure was damaged by falling rocks on the top, causing the water pipe to lose pressure and resulting in a large waste of water resources.

[0005] Based on the above problems, we designed a collaborative auxiliary device for underground coal mining that can recycle excess water resources and is more stable and reliable. Utility Model Content

[0006] The technical problem to be solved by the utility model is to provide a coal mine underground mining cooperative auxiliary device which can realize the recovery of excess water resources and is more stable and reliable.

[0007] In order to solve the above problems, the present invention adopts the following technical solutions:

[0008] A collaborative auxiliary device for underground coal mining includes a return pipe, a water inlet pipe, a spray module and a guard plate. The spray module is connected in series between the return pipe and the water inlet pipe, and the guard plate is installed between adjacent spray modules. The conveyor belt for transporting coal passes through the inner side of the spray module.

[0009] Preferably, the spray module includes an outer shell, and side panels are welded to the front and rear sides of the outer shell, and the side panels and the outer shell are combined to form a water storage chamber, and a water outlet pipe is installed on the outer side of the outer shell, and the water outlet pipe is connected to the return pipe, and a spray pipe is installed at the inner upper position of the outer shell, one end of the spray pipe is closed, and the other end is connected to the water inlet pipe, and an atomizing nozzle is installed at the lower part of the spray pipe; the water inlet pipe passes through the interior of the outer shell, and the guard plate is installed between two adjacent outer shells; the height of the return pipe is lower than the height of the upper edge of the side panel.

[0010] Preferably, the shell is made of steel and is circular. The bottom of the shell is processed to form a flat surface, through which the shell contacts the ground.

[0011] Preferably, inside the shell, a connector is welded between the shell and the side plate, a metal filter is supported between the shell and the side plate by the connector, and the water outlet pipe is located below the metal filter.

[0012] Preferably, the metal filter is ∧-shaped.

[0013] Preferably, a filter box is connected in series to the water outlet pipe, a box cover is installed on the upper end of the filter box, and filter cotton is filled in the filter box.

[0014] The beneficial effects of the utility model are:

Therefore, they cannot be understood as limitations on the present invention.

[0027] In addition, in the description of the present invention, “a plurality of” means at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0028] In this utility model, unless otherwise specified or limited, the terms "disposed," "socketed," "connected," "through," and "inserted" should be understood in a broad sense. For example, they can refer to fixed or detachable connections, or integration; mechanical or electrical connections; direct or indirect connections through an intermediate medium; internal communication between two components or interaction between two components, unless otherwise specified. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0029] See Figure 1 The shown device is a coal mine underground mining cooperative auxiliary device, comprising a return pipe 1, a water inlet pipe 2, a spray module 3 and a guard plate 4. The spray module 3 is connected in series between the return pipe 1 and the water inlet pipe 2, and the guard plate 4 is installed between adjacent spray modules 3. The conveyor belt for transporting coal passes through the inner side of the spray module 3.

[0030] In the above technical solution, the spray module 3 is installed on the ground, and the conveyor belt for transporting coal ore passes through the spray module 3.

[0031] One end of the water inlet pipe 2 is closed, and the other end is connected to the water supply equipment, which is a pump station to maintain sufficient water pressure in the water inlet pipe 2. One end of the return pipe 1 is closed, and the other end is connected to the return pool.

[0032] The spray module 3 is used to spray the coal ore passing through to reduce dust, thereby reducing dust during transportation.

[0033] The guard plate 4 connected between adjacent spray modules 3 can play a certain protective role and prevent falling objects from above the channel from falling onto the conveyor belt and causing damage to the belt conveyor.

[0034] For the hardened area on the channel top, the guard plate 4 may not be installed.

[0035] See Figure 2 and Figure 3 As shown, the spray module 3 includes a shell 301, and side panels 302 are welded to the front and rear sides of the shell 301. The side panels 302 and the shell 301 cooperate to form a water storage chamber 303. A water outlet pipe 304 is installed on the outside of the shell 301, and the water outlet pipe 304 is connected to the return pipe 1. A spray pipe 305 is installed at the upper inner position of the shell 301, and one end of the spray pipe 305 is closed, and the other end is connected to the water inlet pipe 2. An atomizing nozzle 306 is installed at the lower part of the spray pipe 305; the water inlet pipe 2 passes through the inside of the shell 301, and the guard plate 4 is installed between two adjacent shells 301; the height of the return pipe 1 is lower than the upper edge height of the side panel 302.

[0036] In the above technical solution, most of the atomized water vapor sprayed by the atomizing nozzle 306 acts on the surface of the conveyor belt, and it and part of the water vapor condense and fall into the water storage chamber 303.

[0037] The water storage chamber 303 can be used to recycle water resources and reduce the overall water consumption of the coal mine.

[0038] See Figure 2 and Figure 3 As shown, the shell 301 is made of steel and is circular. The bottom of the shell 301 is processed to form a flat surface, which contacts the ground.

[0039] The circular shell 301 has a stronger ability to resist deformation when the top is impacted.

[0040] See Figure 2 and Figure 4 As shown, inside the shell 301 , a connector 331 is welded between the shell 301 and the side panel 302 , and a metal filter 332 is supported between the shell 301 and the side panel 302 by the connector 331 , and the water outlet pipe 304 is located below the metal filter 332 .

[0041] The metal filter 332 is in a ∧ shape.

[0042] During the coal transportation process, due to the vibration of the conveyor belt, some coal ore may fall. The metal filter 332 can intercept the coal ore to prevent the coal ore from clogging the water outlet pipe 304 after falling.

[0043] The mesh size of the metal filter 332 is about 30 meshes and is in a ∧ shape, so that the fallen coal ore is guided to both sides of the metal filter 332, which is convenient for manual cleaning.

[0044] See Figure 3 As shown, a filter box 3331 is serially connected to the water outlet pipe 304 , a box cover 3332 is installed on the upper end of the filter box 3331 , and filter cotton is filled in the filter box 3331 .

[0045] This technical solution is mainly aimed at simple filtration of the recycled water.
