Description

Technical Field

[0001] This utility model belongs to the field of coal energy, specifically relating to a circulating cooling device for a gas extraction pump. Background Technology

[0002] Gas extraction pumps are key equipment used in coal mines and other mines to extract and discharge gas (mainly methane). Their core function is to use mechanical power to extract gas from coal seams, goafs, or roadways, reduce the gas concentration in the mine, ensure safe production, and realize the resource utilization of gas.

[0003] The cooling devices of traditional gas extraction pumps in the present technology may only rely on simple air cooling or water cooling, which has low cooling efficiency and is difficult to meet the heat dissipation requirements during high-load operation. This leads to excessively high equipment temperature, affecting performance and lifespan. Furthermore, if the cooling water contains impurities such as dust and rust, it can clog pipes, damage equipment, affect the cooling effect, and even cause equipment failure. If the heat generated during equipment operation cannot be dissipated in time, it will cause the equipment temperature to rise, affecting performance and stability.

[0004] Therefore, existing gas extraction pumps suffer from poor cooling performance, lack of filtration and purification of cooling water, and heat dissipation issues during use. Utility Model Content

[0005] To overcome the problems of poor cooling effect, lack of filtration and purification of cooling water, and heat dissipation of existing gas extraction pumps during use, a circulating cooling device for gas extraction pumps is proposed.

[0006] The technical solution of this utility model is as follows: a circulating cooling device for a gas extraction pump, including a protective shell, a filter screen, and a heat-conducting pipe. A partition fixing frame is provided on the inner wall of the protective shell. A water storage tank and a filter box are placed below the partition fixing frame, and the water storage tank and filter box are interconnected. A cooling water tank, a compressor, a cooling fan, and an evaporator are placed inside the protective shell at the right end of the partition fixing frame. Multiple clamping blocks are fixedly connected inside the filter box. An mounting plate is installed on the upper end of the filter box, and multiple filter screens are fixedly connected to the lower end of the mounting plate. The filter screens are installed on the clamping blocks. The filter box and the cooling water tank are interconnected. A connecting box is connected through the lower end of the cooling water tank, and the connecting box is connected to a cover. A cooling heat-conducting pipe is provided inside the cooling water tank, and the heat-conducting pipe is interconnected with the compressor. The other end of the compressor is connected to an evaporator. The output end of the water pump is interconnected with the gas collection pump.

[0007] Preferably, the front end of the protective shell is fixedly connected to an outer frame, and the inner front edge of the outer frame is fixedly connected to a second heat dissipation and dustproof mesh for dust prevention, and the front end of the protective shell is provided with a first groove.

[0008] Preferably, the rear end of the protective shell has a second groove for maintenance, and a maintenance cover is installed on the second groove. The right end of the protective shell has two first heat dissipation and dustproof meshes, and the upper end of the protective shell has two mounting slots for subsequent fan installation.

[0009] Preferably, the upper end of the water storage tank is connected to a second water tank inlet pipe, and the front end of the water storage tank is connected to a first water tank inlet pipe, which is installed on the first tank body.

[0010] Preferably, the front end of the cooling water tank is threaded with a cover, and the heat pipe is installed on the cover.

[0011] Preferably, the evaporator and cooling fan are installed in an external frame, with the cooling fan located behind the evaporator.

[0012] Preferably, the evaporator, compressor, and heat pipes on the cover form a heat circulation channel.

[0013] The beneficial effects of this utility model are as follows: By setting up components such as a cooling water tank, heat conduction pipe, compressor, and evaporator to construct a heat circulation channel, the water in the cooling water tank of the refrigeration equipment is used to cool the gas extraction component through the pipes on the water pump, which effectively improves the cooling effect; at the same time, a filter box is set up, and multiple filter screens are installed in the box through clamping blocks and mounting plates, so that the cooling water is filtered and purified before entering the cooling water tank, preventing impurities from affecting the operation of the equipment and extending its service life.

A heat circulation channel is constructed by setting up components such as the cooling water tank 3, heat pipe 303, compressor 4, and evaporator 402. The water in the cooling water tank 3 is cooled by the refrigeration equipment, and then the gas extraction component is cooled by the pipe on the water pump 304, which effectively improves the cooling effect. At the same time, a filter box 201 is set up. Multiple filter screens 204 are installed in the box by clamping and placing blocks 202 and mounting plates 203, so that the cooling water is filtered and purified before entering the cooling water tank 3, preventing impurities from affecting the operation of the equipment and extending its service life.

[0022] Please see Figures 1-3In this embodiment, an outer frame 104 is fixedly connected to the front end of the protective shell 1. A second heat dissipation and dustproof mesh 105 for dust prevention is fixedly connected to the front edge of the inner wall of the outer frame 104. A first groove 103 is opened through the front end of the protective shell 1. A second groove 106 for maintenance is opened at the rear end of the protective shell 1. A maintenance cover 107 is installed on the second groove 106. Two first heat dissipation and dustproof meshes 102 are provided at the right end of the protective shell 1. Two mounting slots 101 for subsequent fan installation are opened through the upper end of the protective shell 1. The second heat dissipation and dustproof mesh 105 on the protective shell 1, the two first heat dissipation and dustproof meshes 102 at the right end, and the reserved mounting slots 101 for subsequent fan installation are designed to help dissipate heat inside the device. At the same time, the first heat dissipation and dustproof meshes 102 and the second heat dissipation and dustproof meshes 105 can also prevent dust from entering the device and avoid dust affecting the performance and heat dissipation effect of the equipment.

[0023] Please see Figures 3-5 In this embodiment, a second water tank inlet pipe 206 is fixedly connected to the upper end of the water storage tank 2, and a first water tank inlet pipe 205 is fixedly connected to the front end of the water storage tank 2.
