[0013] Compared with the prior art, by providing a main body and a spiral filter, when in use, when the gas enters the main body, it hits the spiral filter, and the dust in the gas will adhere to the outer wall at the top of the spiral filter.

[0022] Reference Figure 1-6 The utility model provides a filter used in an air source heat pump system: it includes a main pipe body 1, a mounting pipe 2 is fixedly installed on the top of the main pipe body 1, and connecting pipes 3 are fixedly installed on the bottom of the main pipe body 1 and the top of the mounting pipe 2; a filter assembly is installed at the bottom of the mounting pipe 2; the filter assembly is located on the inner wall of the main pipe body 1 and is used to filter dust in the air.

[0023] First, weld the two connecting pipes 3 to the ports of the air inlet pipe, and then install the filter assembly inside the main pipe body 1 through the installation pipe 2, and then install the main pipe body 1 and the installation pipe 2 between the two connecting pipes 3. When in use, the gas enters the main pipe body 1 through the air inlet pipe machine, and is filtered by the filter assembly to filter out dust in the gas, and then discharged into the heat pump.

[0024] The filter assembly includes a support shaft 5 and a spiral filter screen 6. The support shaft 5 is fixedly connected to the bottom of the mounting tube 2, and the spiral filter screen 6 is fixedly connected to the outer wall of the support shaft 5. The support shaft 5 and the spiral filter screen 6 are both located on the inner wall of the main tube 1.

[0025] When the gas enters the main body 1, it hits the spiral filter 6, and the dust in the gas adheres to the outer wall at the top of the spiral filter 6. Then the gas continues to rotate downward along the spiral outer wall of the spiral filter 6, allowing the remaining dust to continuously hit the spiral filter 6 at the bottom.

[0026] The inner wall of the mounting tube 2 is fixedly connected with a first support frame 4, the top of the support shaft 5 is fixedly connected to the inside of the first support frame 4, the inner wall of the main pipe body 1 is fixedly connected with a second support frame 7, the inside of the second support frame 7 is fixedly connected with a limiting seat 8, and the bottom of the support shaft 5 is installed inside the limiting seat 8.

[0027] The support shaft 5 can be fixedly connected to the bottom of the mounting tube 2 through the first support frame 4 ; the support shaft 5 can be firmly fixed inside the main tube body 1 through the limiting seat 8 .

[0028] The main pipe body 1 and the mounting pipe 2 are threadedly connected, and the top of the mounting pipe 2 and the bottom of the main pipe body 1 are both provided with internal threads 9, and the thread rotation directions of the two internal threads 9 are opposite. The two connecting pipes 3 are both provided with external threads 10 at one end close to the main pipe body 1 and the mounting pipe 2, and the external threads 10 correspond to the threads of the internal threads 9.

[0029] Because the internal threads 9 at the top of the mounting tube 2 and the bottom of the main body 1 rotate in opposite directions, the main body 1 and the mounting tube 2 can be placed between the two connecting tubes 3 during installation, and then the main body 1 and the mounting tube 2 can be rotated in the same direction at the same time to fix the main body 1 and the mounting tube 2 between the two external threads 10.

[0030] The main pipe body 1 is composed of a copper pipe 101 and an antifreeze protection layer 102 . The copper pipe 101 is located in the main body of the main pipe body 1 , and the antifreeze protection layer 102 is located on the outer wall of the copper pipe 101 . The antifreeze protection layer 102 is sprayed on the outer wall of the copper pipe 101 with polyethylene material.

[0031] The copper tube 101 has good corrosion resistance and oxidation resistance; the antifreeze protection layer 102 has good durability and antifreeze properties.

[0032] The spiral filter 6 is composed of an activated carbon filter layer 601 and a polyester needle felt 602 . The activated carbon filter layer 601 is located at the bottom of the spiral filter 6 , and the polyester needle felt 602 is located at the top of the activated carbon filter layer 601 .

[0033] The activated carbon filter layer 601 can filter and remove odors in the air; the polyester needle-punched felt 602 can resist the corrosion of chemical substances such as acids and alkalis, and has the advantages of being easy to clean and not easy to deform.

[0034] Working principle: First, the two connecting pipes 3 are welded to the ports of the air inlet pipe, and then the support shaft 5 is driven to be installed inside the main pipe body 1 through the mounting pipe 2, and the bottom of the support shaft 5 is installed in the limit seat 8.

[0035] Next, place the main pipe body 1 and the mounting pipe 2 between the two connecting pipes 3, and then rotate the main pipe body 1 and the mounting pipe 2 in the same direction at the same time. Because the rotation directions of the internal threads 9 at the top of the mounting pipe 2 and the bottom of the main pipe body 1 are opposite, the main pipe body 1 and the mounting pipe 2 are fixedly installed between the two external threads 10.

[0036] Then when the gas enters the main body 1, it hits the spiral filter 6, and the dust in the gas will adhere to the outer wall at the top of the spiral filter 6. Then the gas continues to rotate downward along the spiral outer wall of the spiral filter 6, allowing the remaining dust to continuously hit the spiral filter 6 at the bottom; during filtering, the activated carbon filter layer 601 can be used to filter and remove odors in the air; and the polyester needle felt 602 can filter out dust in the gas.

[0037] After use, the spiral filter 6 can be removed and cleaned with clean water.
