Description

Technical Field

[0001] The utility model relates to the technical field of mine ventilation, and particularly relates to an anti-blocking device for mine ventilation pipes. Background Art

[0002] The anti-blocking device for mine ventilation pipes is a crucial component in the mine ventilation system. Its main purpose is to prevent the ventilation pipes from being blocked, which may affect the ventilation effect of the mine, and thus ensure the safe production of the mine and the health of the operating personnel.

[0003] Most of the existing mine ventilation devices adopt air conveying equipment such as exhaust fans and are equipped with filter nets to block larger solid particles from entering the ventilation system. However, after long-term use, these filter nets are extremely prone to being blocked by dust and fine particles, resulting in a decrease in ventilation efficiency and even a complete loss of ventilation capacity. The traditional solution usually requires manual regular inspection and cleaning of the filter nets, which is not only time-consuming and laborious but also inefficient and difficult to meet the requirements of continuous production in mines. In addition, it is often difficult to accurately judge the degree of blockage of the filter nets during manual inspection, leading to untimely or excessive cleaning, further increasing the maintenance cost and difficulty. Therefore, an anti-blocking device for mine ventilation pipes is proposed to solve the above problems. Content of the Utility Model

[0004] In view of the deficiencies of the prior art, the utility model provides an anti-blocking device for mine ventilation pipes to overcome the above deficiencies in the prior art.

[0005] The technical solution for the utility model to solve the above technical problems is as follows: An anti-blocking device for mine ventilation pipes includes a rectangular pipe for mine ventilation. A filter net is fixedly installed inside the rectangular pipe. An externally threaded cylinder penetrating through to its interior is threadedly installed at the top of the rectangular pipe. The externally threaded cylinder is located in front of the filter net. A wind speed sensor located inside the rectangular pipe is fixedly installed at the bottom of the externally threaded cylinder. A controller electrically connected to the wind speed sensor is fixedly installed at the top of the rectangular pipe. A long strip-shaped shower head located at the back of the filter net is fixedly installed on the upper top wall of the rectangular pipe. The water spraying end of the long strip-shaped shower head faces the filter net. A first water pipe penetrating through to the outside of the rectangular pipe is fixedly installed on the left side of the long strip-shaped shower head. A storage box located at the back of the long strip-shaped shower head is fixedly installed at the top of the rectangular pipe. Two electric push rods penetrating through to the inside of the rectangular pipe are fixedly installed at the top of the storage box. A brushing structure for cleaning the stains on the back of the filter net is arranged at the bottom of the two electric push rods. Both the brushing structure and the two electric push rods are electrically connected to the controller.

[0006] The beneficial effects of the present utility model are as follows: The rectangular duct is used for ventilation in mine operations. When the wind speed sensor detects that the wind speed in front of the filter screen is small, it means that the filter screen is blocked. Subsequently, the controller controls the activation of two electric push rods and the brushing structure. The two electric push rods expand and contract to drive the brushing structure to move up and down. When the brushing structure operates, it can brush the filter screen, thereby significantly reducing labor costs and improving cleaning efficiency.

[0007] On the basis of the above technical solution, the present utility model can also be improved as follows.

[0008] Further, the brushing structure includes a mounting frame fixedly installed at the telescopic ends of the bottoms of two electric push rods. A motor is fixedly installed on the left side of the mounting frame. The output end of the motor is fixedly installed with a brush roller that penetrates into the interior of the mounting frame. The brush roller is rotatably installed inside the mounting frame, and the brush roller contacts the back of the filter screen.

[0009] Further, a water pump is fixedly installed on the left side of the rectangular duct. The water pump is electrically connected to the controller. The output end of the water pump is fixedly connected to a first water pipe, and the extraction end of the water pump is fixedly installed with a second water pipe connected to an external water source.

[0010] Further, a tee is installed at the bottom of the rectangular duct, and the tee is located on the front and back sides of the filter screen.

[0011] Further, a solenoid valve that penetrates into its interior is fixedly installed on the outside of the tee, and the solenoid valve is electrically connected to the controller.

[0012] Further, a handle is fixedly installed at the top of the external thread cylinder. Description of the Drawings

[0021] The principles and features of the present utility model will be described below with reference to the attached drawings. The examples given are only used to explain the present utility model and are not intended to limit the scope of the present utility model.

[0022] Embodiment 1, a mine ventilation duct anti-blocking device, includes a rectangular duct 1 for mine ventilation. A filter screen 2 is fixedly installed inside the rectangular duct 1. An external thread cylinder 3 penetrating through to its interior is threadedly installed at the top of the rectangular duct 1. The external thread cylinder 3 is located in front of the filter screen 2. A wind speed sensor 4 located inside the rectangular duct 1 is fixedly installed at the bottom of the external thread cylinder 3. A controller 5 electrically connected to the wind speed sensor 4 is fixedly installed at the top of the rectangular duct 1. A long strip shower head 6 located at the back of the filter screen 2 is fixedly installed on the upper top wall of the rectangular duct 1. The water spraying end of the long strip shower head 6 faces the filter screen 2. A first water pipe 7 penetrating through to the outside of the rectangular duct 1 is fixedly installed on the left side of the long strip shower head 6. A storage box 8 located at the back of the long strip shower head 6 is fixedly installed at the top of the rectangular duct 1. Two electric push rods 9 penetrating through to the inside of the rectangular duct 1 are fixedly installed at the top of the storage box 8. A brushing structure for cleaning the stains on the back of the filter screen 2 is arranged at the bottom of the two electric push rods 9. Both the brushing structure and the two electric push rods 9 are electrically connected to the controller 5.

[0023] During use, the rectangular duct 1 is used for mine operation ventilation. The installed filter screen 2 can block larger solid particles from entering the ventilation system. When the wind speed sensor 4 detects that the wind speed in front of the filter screen 2 is small, it means that the filter screen 2 is blocked. After the wind speed sensor 4 transmits the blockage signal to the controller 5, the controller 5 controls the two electric push rods 9 and the brushing structure to start. Then, the water from the outside enters the inside of the long strip shower head 6 through the first water pipe 7 and is sprayed on the filter screen 2. After the two electric push rods 9 start, they stretch and drive the brushing structure to lift and lower. The brushing structure operates to brush the filter screen 2. After the filter screen 2 is cleaned, the inside of the rectangular duct 1 will be unobstructed. At this time, the labor cost can be significantly reduced and the cleaning efficiency can be improved.
