Description

Technical Field

[0001] The invention relates to the technical field of softened water treatment, in particular to a filtering device of softened water treatment equipment. Background Art

[0002] Softening water treatment reduces the hardness of water by removing calcium and magnesium ions from the water, which is mainly achieved through ion exchange resin. Softening water treatment equipment usually consists of a controller, a resin tank and a salt tank. Its working principle is to adsorb calcium and magnesium ions in the water through the resin, thereby reducing the hardness of the water. When the resin is saturated with adsorption, it needs to be regenerated with high-concentration salt water to restore the exchange capacity of the resin. Softening water treatment has a wide range of applications, including bathrooms, kitchens, laundry, heating, boilers, etc. Since the water quality after softening treatment has low hardness, it can effectively prevent the formation of scale, reduce equipment damage and increase the service life of the equipment. In addition, softening water treatment can also improve the taste of water, making it suitable for drinking and cooking.

[0003] In the existing technology, softening water treatment equipment uses ion exchange technology to remove calcium, magnesium and other ions in water to turn hard water into soft water. However, soft water contains a large amount of sodium ions. Long-term use of softening water will lead to excessive scale, which will affect the service life of the filter element of the softening water treatment equipment. Therefore, it is often necessary to filter out the scale. Traditional scale filtering methods mostly use filter nets to filter them, but the position of the filter net is usually in a fixed state when in use. After long-term use, the surface of the filter net may be blocked by scale. At this time, the staff often need to dismantle the filter net for cleaning or replacement. During this process, the staff may need to spend a long time on disassembling and cleaning the filter net, which may affect the use effect of the softening water treatment equipment.

[0011] By adopting the above technical solution, when in use, the staff connects the external water pipe to the water inlet of the control valve, and at the same time, the staff adds salt water to the inside of the salt well box, and then the staff rotates the first sealing plate at the bottom of the treatment box to open and add the ion exchange resin to the inside of the resin box, and then the control valve sends the external water source and the salt water inside the salt well box into the inside of the resin box. At this time, the ion exchange resin inside the resin box will exchange and adsorb the calcium and magnesium ions in the water to make it soft water, and then the salt water will flush the resin layer, replace and discharge the calcium and magnesium ions on its surface, thereby maintaining the continuous softening ability of the ion exchange resin, and then when the staff releases the softened water inside the treatment box through the drain valve, due to the potential energy of the water flow, the flow inside the treatment box The water will drive the transmission paddle wheel to rotate, and the rotation of the transmission paddle wheel will drive the third rotating shaft and the driving bevel gear to rotate, and then under the gear meshing transmission action of the driving bevel gear and the driven bevel gear, the driven bevel gear will drive the second rotating shaft and the spur gear on its surface to rotate. At this time, under the gear meshing transmission action of the two spur gears, the first rotating shaft will drive the adjusting sleeve and the connecting frame at its bottom to rotate, and then when the two adjusting plates at the bottom of the positioning sleeve and the two adjusting plates at the top of the adjusting sleeve contact and intertwine, the position of the positioning sleeve is fixed, and the adjusting sleeve is extruded by the adjusting plates. The pressure will drive the mounting sleeve and multiple mounting rods to move downward, and then the multiple second springs will be squeezed. At this time, the two cleaning brushes at the bottom of the connecting frame will contact the surface of the filter bucket and remove scale on its surface. Brush cleaning, at this time the two cleaning brushes are always moving up and down and rotating to clean the scale on the surface of the filter bucket, so as to prevent the cleaning brushes from always sticking to the surface of the filter bucket and rotating, causing the scale to be broken up and discharged through the mesh of the filter bucket. At this time, the soft water containing scale cannot pass through the filter bucket and will enter the inside of the diverter cover. Then, the soft water with scale inside the diverter cover will enter the inside of the filter cartridge through the fixed frame. At this time, the first filter cover and the second filter cover in the graded filter tube inside the filter cartridge will perform particle size classification and filtration on the scale. At the same time, the activated carbon placed inside the box will perform deep filtration on the fine particles in the scale, and then the soft water that has been descaled through the graded filter tube for multi-stage filtration will enter the inside of the branch pipe and the soft water inside the treatment box through the diverter pipe. When the scale inside the graded filter tube is full, the staff can directly see the scale accumulation through the graded filter tube made of transparent acrylic material, and then the staff can take out the filter cartridge from the inside of the fixing frame and unscrew the two fixing sleeves inside it. Then the staff can take out the graded filter tube from the inside of the filter cartridge and remove the first filter cover, the second filter cover and the graded filter tube to clean the scale. In this process, since the scale inside the treatment box is removed inside the graded filter tube, the filter bucket can be avoided from being blocked by scale during long-term use. At the same time, since the filter cartridge is outside the treatment box, it is convenient for the staff to directly clean the scale inside the filter cartridge, thereby achieving the purpose of removing the scale inside the treatment box.At the same time, it is convenient to directly clean the filtered scale.

[0012] Preferably, there are two mounting plates, both of which are fixedly sleeved on the inner circular wall of the fixing frame, a plurality of mounting caps are fixedly installed on the bottom surface of the mounting plates, the internal movably sleeved of the mounting caps is provided with a first spring, the internal movably sleeved of the mounting caps is provided with a connecting column, the internal movably sleeved of the mounting plates is provided with a limiting shell, the bottom surface of the limiting shell is fixedly installed with a plurality of the connecting columns, the top surfaces of the two fixing sleeves are both fixedly installed with embedded rings, and the embedded rings are movably sleeved with the inner circular wall of the limiting shell.

[0013] By adopting the above technical solution, when the staff installs the filter cartridge into the interior of the fixing frame, the embedded rings on the surfaces of the two fixing sleeves will squeeze the limit shell and enter the interior of the limit shell. At this time, the rebound force of the multiple first springs will push the limit shell to move, so that it continues to press down on the fixing sleeve, thereby facilitating the positioning of the filter cartridge during installation.

[0014] Preferably, a pressure ring is fixedly mounted on the inner top surface and the inner bottom surface of the fixing frame, and a sealing gasket is fixedly mounted on the top surfaces of the two fixing sleeves.

[0015] By adopting the above technical solution, when the filter cartridge enters the interior of the fixing frame, the two pressure rings will squeeze the sealing gaskets on the surfaces of the two fixing sleeves, and then the deformed sealing gaskets will fill between the fixing frame and the fixing sleeve, thereby improving the sealing between the filter cartridge and the fixing frame and preventing leakage between the fixing frame and the filter cartridge.

[0016] Preferably, a second sealing strip is fixedly installed on one side of the diverter cover, and a first sealing strip is fixedly installed on the top surface of the first sealing plate.

Then, the soft water with scale in the diverter cover 2 enters the interior of the filter cartridge 28 through the fixing frame 9. At this time, the first filter cover 39 and the second filter cover 40 in the graded filter tube 38 inside the filter cartridge 28 will clean the scale. The scale is filtered according to particle size classification, and the activated carbon placed inside the box 41 will deeply filter the fine particles in the scale, and then the soft water that has been filtered and descaled by multi-stage filtration through the graded filter tube 38 will enter the inside of the branch pipe 8 through the diversion pipe 27 and be discharged together with the soft water inside the treatment box 1. When the scale inside the graded filter tube 38 is full, the staff can directly see the scale accumulation phenomenon through the graded filter tube 38 made of transparent acrylic material, and then the staff can take out the filter cartridge 28 from the inside of the fixing frame 9 and unscrew the two fixing sleeves 37 inside it. Then the staff can take out the graded filter tube 38 from the inside of the filter cartridge 28 and dismantle the first filter cover 39, the second filter cover 40 and the graded filter tube 38 to clean the scale.During this process, since the scale inside the treatment box 1 is removed inside the graded filter tube 38, the filter bucket 23 can be prevented from being blocked by scale during long-term use. At the same time, since the filter cartridge 28 is outside the treatment box 1, it is convenient for the staff to directly clean the scale inside the filter cartridge 28, thereby achieving the effect of removing the scale inside the treatment box 1 and facilitating the direct cleaning of the filtered scale.
