Description

Technical Field

[0001] The utility model relates to the technical field of heating equipment, in particular to a heating and HVAC water inlet filtering mechanism. Background Art

[0002] HVAC is an integral part of a building, including three aspects: heating, ventilation, and air conditioning. When heating, the heating group will first roughly filter the water. However, since the heating water is recycled and repeatedly heated, the water hardens and generates impurities. In addition, the heating pipes are only used in winter, and often due to the long period of static, a lot of rust is generated in the heating pipes. When used again, they are easily washed away by the water flow. As the distance the water flows through the pipes increases, the rust accumulates, and the water impurities adsorb each other and increase in volume, which can easily cause pipe blockage. Prior art announcement number CN217410006U proposes a heating pipe filtering device, including a structural body, a movable pipe is provided at the middle position of the structural body, a first docking ring is provided on one side of the outer portion of the movable pipe, and a plurality of groups of first external threads are evenly provided on the outer side of the first docking ring, and a second docking ring is provided on the outer side of the movable pipe away from the first docking ring, and a plurality of groups of second external threads are evenly provided on the outer side of the second docking ring. However, when the pipeline is in use, the filter screen is easily damaged after long-term filtering, the filtering effect is reduced, and impurities accumulate on one side of the filter screen, which will clog the filter screen. There is a lack of a suitable collection mechanism, and it is inconvenient to discharge the material after collecting a certain amount. Utility Model Content

The mounting frame 15 is fixedly mounted on the inner wall of the left conical tube 2, the telescopic rod 16 is rotatably mounted in the middle of the mounting frame 15, the left end of the telescopic rod 16 is equipped with a turbine 17, the right end of the telescopic rod 16 is telescopically equipped with a cleaning brush holder 18, the cleaning brush holder 18 is set to a shape that matches the left side of the filter plate 13, the retaining ring 19 is mounted on the inner wall of the conical tube 2 on the right side of the mounting frame 15, the drain pipe 20 is connected to the bottom of the left end conical tube 2, the drain pipe 20 is provided with a valve, and the drain pipe A collection box 21 is installed at the output end of 20, a cleaning plate is provided at the front end of the collection box 21, the top of the collection box 21 is mounted on the bottom of the filter box 1 through a connecting frame 22, a drain hole is provided in communication with the annular groove of the plug-in plate 8 and the bottom of the filter box 1, a stud 23 is fixedly mounted on the lower part of the rear side wall of the filter box 1, an adjustment slot is provided on the upper part of the support frame 24, a C-shaped clamping plate 25 is sleeved on the stud 23, a fixing nut 26 is screwed on the stud 23, and a plurality of fixing holes are provided on the lower part of the support frame 24;

[0019] After the water inlet pipe 3 and the water outlet pipe 4 are connected to the heating and HVAC water inlet pipe through the connecting flange 5, the supplied water enters the water inlet pipe 3 and is discharged through the water outlet pipe 4. The sealing ring 6 can ensure the sealing of the connection, and the filter box 1 can be supported and fixed by the support frame 24 to ensure stability during use. Loosening the fixing nut 26 can make the support frame 24 slide on the rear side wall of the filter box 1, which is convenient for adjusting the support height and convenient for installation. Tightening the fixing nut 26 can fix the support frame 24 through the C-shaped clamping plate 25. When the water flows from the left end of the filter box 1 to the right end, the filter screen plate 13 filters the water. Because the side surface of the filter screen plate 13 close to the output end is a conical structure, the conical structure has a secondary filtering effect on impurities. When water flows, the sealing slip ring 11 on the filter screen plate 13 can slide left and right inside the annular groove under the elasticity of the spring 12, pushing the impurities to one side for easy concentration, and pulling the pull plate 9 through the sealing The cover plate 14 is taken out of the insertion slot of the filter box 1, which is convenient for replacing the filter screen plate 13.

When it is working, after the water inlet pipe 3 and the water outlet pipe 4 are connected to the heating and HVAC water inlet pipe through the connecting flange 5, the supplied water enters from the water inlet pipe 3. When the water flows from the left end to the right end of the filter box 1, the filter plate 13 filters the water. Because the side surface of the filter plate 13 close to the output end is a conical structure, the conical structure has a secondary filtering effect on impurities. When the water flows through, the turbine 17 drives the telescopic rod 16 to rotate, and the telescopic rod 16 drives the cleaning brush holder 18 to rotate to clean the left end of the filter plate 13 to prevent debris from blocking the filter plate 13. When water flows, the seal on the filter plate 13 Under the elasticity of the spring 12, the slip ring 11 can slide left and right inside the annular groove, pushing the impurities to one side for easy concentration. The cleaned impurities fall to the bottom of the left-end conical tube 2 through the drain hole, and are collected into the collection box 21 through the drain pipe 20. Impurities and the like accumulate inside the collection box 21. After long-term use of the device, a large amount of impurities accumulate inside the collection box 21. Close the valve on the drain pipe 20, remove the cleaning plate at the front end of the collection box 21, and discharge the internal impurities and the like. Pull the pull plate 9 through the sealing cover plate 14 to remove the plug-in plate 8 from the plug-in slot of the filter box 1, so as to facilitate the replacement of the filter mesh plate 13. The filter box 1 can be supported and fixed by the support frame 24.
