Description

Technical Field

[0001] The utility model relates to the technical field of heating equipment, in particular to an antifreeze heating device with dust removal and cleaning functions. Background Art

[0002] Wellhead antifreeze is an important guarantee for safe production in coal mines in winter. Wellhead icing will affect the normal operation of mine production equipment, and even cause serious accidents such as stuck tanks and mine shutdowns. Ice chips falling after the cages and well walls freeze may also cause casualties to underground personnel. Therefore, wellhead antifreeze is a necessary measure to ensure safe production in mines. Article 102 of my country's "Safety Regulations for Coal Mines" stipulates that the temperature below the air inlet wellhead must be above 2°C. Mine wellhead antifreeze requires a lot of energy. Affected by many factors such as geographical restrictions and environmental climate, mines in many areas need to be kept warm for up to three or four months, accounting for a quarter of the year or even more. There is no doubt that long-term mine wellhead insulation requires a lot of expenses, which increases the production cost of coal mines.

[0003] Mine wellhead antifreeze is an important part of coal mine safety production. The traditional wellhead antifreeze heat exchange device heats the air through steam (high-temperature hot water) and then sends the heated hot air into the well through the fan, that is, the heating mode of heat exchange between steam (high-temperature hot water) and air. However, during the use of the heat exchange device, especially in the mining area, the dust is large and easily adsorbed on the filter screen at the air inlet of the heat exchange device, causing accumulation and clogging, thereby affecting the operation of the fan inside the heat exchange device.

[0004] In order to solve the above problems, we propose an antifreeze heating device with dust removal and cleaning functions to solve the above problems. Utility Model Content

[0020] Example: Refer to Figure 1 - Figure 3 As shown, an antifreeze heating device with dust removal and cleaning functions of the present embodiment includes a heat exchanger 1, and an air inlet 2 is arranged on the upper side of the back of the heat exchanger 1, a ventilation filter 3 is arranged in the inner middle part of the air inlet 2, and a dust cleaning component is arranged on the back of the ventilation filter 3; the dust cleaning component includes an air outlet slot 7, a water spray pipe 8 is arranged in the middle of the top end of the air outlet slot 7, and a plurality of groups of nozzles 9 are arranged in the middle of the side end of the water spray pipe 8, and the plurality of groups of nozzles 9 are equidistantly distributed, and the water outlets of the nozzles 9 and the air outlets of the air outlet slot 7 are both close to the back end surface of the ventilation filter 3; a driving component is arranged in the middle of the left end of the air outlet slot 7, and the driving component is used to drive the air outlet slot 7 to perform lifting and lowering movements, and the driving component includes a left sliding block 10, and the inner middle part of the left sliding block 10 is transmission-connected with a screw rod 5, and the middle of the top end of the screw rod 5 is connected with a driving motor 6.

[0021] Among them, the driving motor 6 drives the screw rod 5 to rotate, so that the left sliding block 10 drives the air outlet slot 7 to move up and down, and at the same time, the water spray pipe 8 and multiple groups of nozzles 9 also move up and down, so that the ventilation filter 3 can be cleaned by wind and sprayed with water, thereby improving the efficiency and cleanliness of removing dust accumulated on the surface of the ventilation filter 3.

[0022] A right sliding block 11 is provided in the middle of the right end of the air outlet slot 7, and a guide rod 12 is provided in the middle of the inner side of the right sliding block 11.
