Description

Technical Field

[0001] The utility model relates to the technical field of filtering equipment, in particular to a fully automatic brush type self-cleaning filter for an assembled heat exchange unit. Background Technique

[0002] A heat exchange unit is a complete heat exchange station composed of multiple components, which has the advantages of compact structure, reliable operation, simple and intuitive operation, etc. It is widely used in systems such as district central heating, central air conditioning, domestic water, and enterprise production. Due to the large volume of the integral heat exchange unit, with the rapid development of technology, the assembled heat exchange unit has gradually entered the market and been widely used.

[0003] After retrieval, the patent with the publication number of CN221099451U discloses a plate type heat exchange unit convenient for replacing a filter. The telescopic plate and the supporting plate of the heat exchange unit form a telescopic structure, and the telescopic plate and the supporting plate form an elastic clamping and limiting structure in the limiting hole through an elastic limiting block, so as to increase the clamping effect between the two groups of supporting plates, and further increase the supporting property of the supporting plate. The supporting plate of the device forms a rotating structure with the filter through a first rotating shaft, an L-shaped connecting rod, and a supporting block, and the L-shaped connecting rod forms a spiral locking structure with the water inlet pipe and the connecting pipe in the spiral groove through a first bolt, so as to fix the L-shaped connecting rod through the first bolt, so as to support the filter through the supporting plate. The concave connecting rod of the device forms a rotating structure with the water inlet pipe and the connecting pipe through a second rotating shaft respectively, and the concave connecting rod and the fixing block form an elastic clamping and limiting structure in the limiting hole through an elastic limiting block, so as to ensure that the filter can be aligned with the water inlet pipe and the connecting pipe through the elastic limiting block clamped in the limiting hole, and then carry out the positioning work of the filter;

[0004] This heat exchange unit can remove and replace the filter, with high flexibility and certain practical effects. However, there is still room for improvement. For example, in this patent, various clamping and locking structures are used to assemble and position the filter, and the steps are relatively cumbersome. In the actual use process, if it is necessary to replace the filter screen or filter element in the filter, it is necessary to first remove the filter, and then remove the filter to take out the filter element for replacement, which is too cumbersome and affects the heat exchange efficiency of the heat exchange unit. Content of the Utility Model

[0005] The purpose of the utility model is to solve the deficiencies existing in the prior art, and to propose a fully automatic brush type self-cleaning filter for an assembled heat exchange unit.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

The filtering component includes a monitoring pipe, on the surface of which a flow sensor is fixedly connected. The right end of the monitoring pipe is communicated with a filtering cylinder. The right end of the filtering cylinder is fixedly connected with a servo motor. The output end of the servo motor is fixedly connected with a round rod. The left end of the round rod is fixedly connected with a first gear. Inside the inner wall of the filtering cylinder, a circular frame is fixedly connected. Inside the inner wall of the circular frame, a filter screen is fixedly connected. Inside the inner wall of the filtering cylinder, a support rod is fixedly connected. The front end of the support rod is fixedly connected with a positioning ring. Inside the inner wall of the positioning ring, a movable rod is rotatably connected. The left end of the movable rod is fixedly connected with a second gear. The right end of the movable rod is fixedly connected with a porous circular plate. On the right side of the porous circular plate, a number of cleaning brushes are fixedly connected. A sewage discharge component is fixedly connected to the surface of the filtering cylinder.

[0008] Preferably, the end of the water inlet pipe away from the input water pump is communicated with the inside of the filtering cylinder, and the input water pump transports water into the filtering cylinder through the water inlet pipe.

[0009] Preferably, a circular through hole adapted to the round rod is opened on the side surface of the circular frame, and the round rod does not affect the rotation effect of the porous circular plate.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0023] Example 1, referring to Figure 1 , Figure 2 and Figure 3 , an automatic brush-type self-cleaning filter for an assembled heat exchange unit, including an assembly bottom plate 1.

Two positioning plates 7 are fixedly connected to the upper surface of the assembly bottom plate 1 through a second bolt 6. An input water pump 8 and an output water pump 9 are respectively fixedly connected to the upper surfaces of the two positioning plates 7. The output end of the input water pump 8 is communicated with a water inlet pipe 10. The input end of the output water pump 9 is communicated with the heat exchanger 5;

[0024] A water inlet is opened on the right side of the heat exchanger 5. A filtering component is fixedly connected to the inner wall of the water inlet. The filtering component includes a monitoring pipe 11. A flow sensor 12 is fixedly connected to the surface of the monitoring pipe 11. The right end of the monitoring pipe 11 is communicated with a filter cartridge 13. The end of the water inlet pipe 10 away from the input water pump 8 is connected to the inside of the filter cartridge 13. A servo motor 14 is fixedly connected to the right end of the filter cartridge 13. The output end of the servo motor 14 is fixedly connected to a round rod 15. The left end of the round rod 15 is fixedly connected to a first gear 16. A circular frame 17 is fixedly connected to the inner wall of the filter cartridge 13. A circular through hole adapted to the round rod 15 is opened on the side surface of the circular frame 17. A filter net 18 is fixedly connected to the inner wall of the circular frame 17;

[0025] The inner wall of the filter cartridge 13 is fixedly connected with a support rod 19. The front end of the support rod 19 is fixedly connected with a positioning ring 20. The inner wall of the positioning ring 20 is rotatably connected with a movable rod 21. The left end of the movable rod 21 is fixedly connected with a second gear 22. The first gear 16 meshes with the second gear 22. The right end of the movable rod 21 is fixedly connected with a porous circular plate 23. The right side of the porous circular plate 23 is fixedly connected with a number of cleaning brushes 24. And the size of the porous circular plate 23 is the same as that of the filter screen 18.

[0026] When the flow sensor 12 monitors that the flow rate in the monitoring pipe 11 is less than the preset threshold, the industrial control host 2 automatically shuts down the heat exchange system, and at the same time turns on the servo motor 14. The servo motor 14 can drive the second gear 22 and the movable rod 21 to rotate through the round rod 15 and the first gear 16, so that the porous circular plate 23 drives a number of cleaning brushes 24 to perform self-cleaning operation on the side of the filter screen 18.

The size of the arc-shaped sealing plate 29 is the same as the size of the arc-shaped hole opened at the position on the surface of the filter cartridge 13 corresponding to the sewage discharge frame 26.

[0028] The blower 27 can blow air on the surface of the filter screen 18 through the air inlet frame 25, so as to blow the scraped impurities into the sewage discharge frame 26 and discharge them through the sewage discharge pipe 30. Since the size of the arc-shaped sealing plate 29 is the same as that of the arc-shaped hole, there will be no leakage in the filter cartridge 13 during normal operation.

[0029] Working principle: The input water pump 8 conveys water to the filter cylinder 13 through the water inlet pipe 10. After filtration, the water is input into the heat exchanger 5 for heat exchange treatment. After the heat exchange is completed, it is discharged through the output water pump 9. When the flow sensor 12 monitors that the flow rate in the monitoring pipe 11 is less than the preset threshold, the industrial control host 2 automatically closes the input water pump 8 and the output water pump 9 and turns on the servo motor 14. The servo motor drives the first gear 16 to rotate through the round rod 15. The first gear 16 drives the second gear 22 and the movable rod 21 to rotate, so that the porous circular plate 23 drives the cleaning brush 24 to perform self-cleaning on the side of the filter screen 18. After scraping off the impurities on the filter screen 18, the fan 27 is started. At the same time, the electric push rod 28 drives the arc-shaped sealing plate 29 to descend. The fan 27 blows air from top to bottom through the air inlet frame 25 to the surface of the filter screen 18, so that the impurities pass through the arc-shaped holes corresponding to the sewage discharge frame 26 on the surface of the filter cylinder 13 and are discharged into the sewage discharge frame 26, and are discharged through the sewage discharge pipe 30, thus realizing the full-automatic cleaning function of the filtration system and improving the filtration effect of the water system in the heat exchanger 5.
