Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of filters, in particular to a filter for hot air pipelines. Background Art
[0002] A filter is an essential device in pipelines conveying media, typically installed at the inlet of pressure reducing valves, pressure relief valves, constant water level valves, and other equipment. The filter consists of a cylinder, a stainless steel filter screen, a sewage discharge unit, a transmission device, and an electrical control unit. After the water to be treated passes through the filter screen, impurities are trapped. When cleaning is necessary, simply remove the removable filter cartridge, treat it, and reinstall it, making it extremely easy to use and maintain.
[0003] The flowing medium in the pipeline, especially the hot air pipeline, often contains a large amount of impurities. Over time, they will accumulate in the radiator, affecting the heat dissipation effect of the radiator and may also cause blockage of the pipeline. At this time, a filter is needed. However, after a long time, some impurities will accumulate on the stainless steel filter screen and block the filter holes on the filter screen. The staff will need to remove the top of the filter and clean the filter screen, which is very troublesome. Summary of the Invention

[0027] See also Figures 1-6 The present invention provides a filter for hot air pipes, comprising
[0028] A filter cartridge 1, with connecting pipes 2 connected to both sides of the filter cartridge 1, a top sealing assembly 3 provided on the top of the filter cartridge 1, and a stainless steel filter screen 4 placed in the inner cavity of the filter cartridge 1;
[0029] The filter cleaning assembly 5 is disposed within the filter cartridge 1 and includes a rotating shaft 51 rotatably connected to the inner cavity of the connecting pipe 2. A circular plate 52 located within the inner cavity of the connecting pipe 2 is fixedly mounted on the upper portion of the rotating shaft 51. A discharge barrel 53 is connected to the bottom of the inner cavity of the filter cartridge 1. A turntable 54 is movably mounted on the outer side of the discharge barrel 53. Pulleys 55 are provided at the bottom of the turntable 54 and the bottom of the rotating shaft 51. A transmission belt 56 is used to connect the two pulleys 55. A brush 57 located within the inner cavity of the stainless steel filter screen 4 is fixedly mounted on the top of the turntable 54. A discharge valve is provided at the bottom of the discharge barrel 53.
[0030] A filter cleaning assembly 5 is provided in the inner cavity of the filter cartridge 1. When the filter is in use, air flows into the filter cartridge 1 through the connecting pipe 2, blowing the circular plate 52 to rotate. The bottom of the circular plate 52 drives the pulley 55 at its bottom to rotate by the rotating shaft 51, and then the transmission belt 56 drives the pulley 55 at the bottom of the turntable 54 to rotate, thereby driving the brush 57 on the turntable 54 to rotate along the outer side of the discharge barrel 53, thereby cleaning the inner side of the stainless steel filter screen 4, avoiding the clogging of the stainless steel filter screen 4 affecting the overall filtering effect, and avoiding the need to disassemble and open the top of the filter cartridge 1 for cleaning once the stainless steel filter screen 4 is clogged, which is convenient for long-term use of this filter.
[0031] A plurality of brushes 57 are provided on the top of the turntable 54. The brushes 57 are evenly distributed along the circumference of the stainless steel filter 4. The brushes 57 fit the inner wall of the stainless steel filter 4. The plurality of brushes 57 improves the efficiency of cleaning impurities on the stainless steel filter 4.
[0032] The inner wall of the rotating disk 54 is in the shape of a trumpet. By utilizing the shape of the rotating disk 54, impurities can be gathered together and discharged from the discharge barrel 53, thereby facilitating the discharge of impurities.
[0033] The bottom of the stainless steel filter screen 4 is provided with a base support assembly 7, which includes a mounting plate 71, a support seat 72, and a placement groove 73. The placement groove 73 is fixedly mounted on the inner wall of the filter cartridge 1, and the mounting plate 71 is fixedly mounted in the placement groove 73. The top of the mounting plate 71 is provided with a support seat 72, and the inner cavity of the support seat 72 is movably sleeved on the bottom of the stainless steel filter screen 4. The bottom of the stainless steel filter screen 4 is connected to the inner wall of the filter cartridge 1 via the base support assembly 7, which facilitates the placement of the stainless steel filter screen 4 and the positioning of the stainless steel filter screen 4.
[0034] The inner cavity of the mounting plate 71 is movably sleeved on the turntable 54, and the inner wall of the stainless steel filter 4 is in contact with the outer side of the turntable 54. The inner wall of the stainless steel filter 4 is in contact with the outer side of the turntable 54, which facilitates the support of the stainless steel filter 4 and improves the stability of the stainless steel filter 4 placed in the filter cartridge 1.
[0035] A scraper 6 is fixedly mounted on the top of the discharge barrel 53, and the bottom of the scraper 6 is in contact with the inner wall of the turntable 54. Because the scraper 6 is provided on the top of the discharge barrel 53, impurities on the turntable 54 can be scraped off by the scraper 6 when the turntable 54 rotates, making it easier to discharge the impurities and avoiding impurities adhering to the inner wall of the turntable 54, making it difficult to discharge the impurities.
[0036] The top sealing assembly 3 includes a first flange 31, a second flange 32, and bolts 33. The first flange 31 is fixedly mounted on the top of the filter cartridge 1. The second flange 32 is located on top of the first flange 31. The first and second flanges 31, 32 are fixedly connected by bolts 33. The first flange 31, the second flange 32, and the bolts 33 on the top of the filter cartridge 1 make the top of the filter cartridge 1 removable, making it easy to access and replace the stainless steel filter screen 4 inside the filter cartridge 1.
[0037] The top sealing assembly 3 also includes a sealing groove 34 and a sealing ring 35. The sealing ring 35 is provided at the top of the first flange 31, and the sealing ring 35 is fixedly mounted at the bottom of the second flange 32, located within the inner cavity of the sealing groove 34. The sealing groove 34 and sealing ring 35 provided between the second flange 32 and the first flange 31 improve the sealing performance of the connection between the first flange 31 and the second flange 32, thereby enhancing the overall sealing performance.
[0038] Working principle: When using this device, the two sides of the filter cartridge 1 are respectively connected to the hot air pipe, and the hot air enters the filter cartridge 1 from a connecting pipe 2 provided with a circular plate 52, and the hot air is filtered through the stainless steel filter screen 4 and discharged from the other connecting pipe 2 on the filter cartridge 1. When the hot air enters the filter cartridge 1, it generates thrust to push the circular plate 52 to rotate. The rotation of the circular plate 52 drives the rotating shaft 51 to rotate, thereby driving the pulley 55 under the rotating shaft 51 to rotate, and the transmission belt 56 drives the pulley 55 at the bottom of the turntable 54 to rotate, thereby driving the turntable 54 to rotate. Since the turntable 54 is provided with a brush 57, the brush 57 is driven to rotate along the inner wall of the stainless steel filter screen 4, cleaning the impurities blocked on the stainless steel filter screen 4, and the impurities fall on the top of the turntable 54. Since the top of the discharge barrel 53 is provided with a scraper 6, the rotary disc 54 rotates and the scraper 6 remains stationary, cleaning the impurities on the turntable 54 into the discharge barrel 53 for subsequent discharge.
