Description

Technical Field

[0001] This application relates to the field of water purification equipment technology, specifically a horizontal manual backwash filter. Background Technology

[0002] A backwash filter is a precision device that uses a filter screen to directly intercept impurities in water, removing suspended solids and particulate matter, reducing turbidity, purifying water quality, and reducing the generation of system dirt, algae, and corrosion. The working principle of a backwash filter mainly includes two stages: forward washing and backwashing.

[0003] Forward washing stage: Water flows through the filter element, and impurities and particulate matter are trapped on the surface of the filter element. As the usage time increases, the amount of impurities on the filter element gradually increases, and the filtration effect gradually decreases.

[0004] Backwashing stage: By changing the direction of water flow, the water flows from the outside of the filter element to the inside, washing away impurities trapped on the surface of the filter element. This not only restores the filtration effect of the filter element, but also extends its service life.

[0005] During the use of backwashing equipment, the impurities that have accumulated on the surface of the filter screen for a long time cannot be completely cleaned by the backwashing action of water pressure difference. Some residues will still remain. Stubborn stains that are difficult to clean for a long time may damage the filtration effect of the filter screen tube.

[0006] Therefore, this application provides a horizontal manual backwash filter to solve the above problems. Utility Model Content

[0007] This application provides a horizontal manual backwash filter, which aims to solve the problems mentioned in the background art, such as the fact that the impurities accumulated on the surface of the filter screen of existing backwash equipment cannot be completely cleaned by the backwashing action of water pressure difference, and some residues will still remain. Stubborn stains that are difficult to clean for a long time may damage the filtration effect of the filter screen tube.

[0008] To achieve the above objectives, this application provides the following technical solution: a horizontal manual backwash filter, comprising a filter housing fixedly mounted on a bracket and a water inlet fixedly mounted at one end of the filter housing, a drain outlet fixedly mounted on the outer wall of the filter housing, a manual backwash valve rotatably mounted on the filter housing, a filter tube fixedly mounted inside the filter housing, a cleaning mechanism for cleaning the inner and outer walls of the filter tube fixedly mounted on the filter housing, and a drain pipe provided at the end of the filter housing away from the water inlet.

[0009] The cleaning mechanism includes a sealing plate fixedly installed on the filter housing at the end away from the water inlet, a drain pipe fixedly installed on the sealing plate and connected to the filter pipe, a first drive motor fixedly installed on the sealing plate, the output shaft of the first drive motor extending through the sealing plate into the filter pipe, and an inner cleaning component fixedly installed on the output shaft of the first drive motor.

[0010] The cleaning mechanism also includes a mounting groove fixedly installed on the filter housing. A second drive motor is fixedly installed on the outer wall of one end of the mounting groove. The output end of the second drive motor extends through the mounting groove and is fixedly installed with a reciprocating screw. A moving block is slidably connected to the reciprocating screw. A scraper ring sleeved on the outer wall of the filter tube is fixedly installed on the moving block. In this way, when using the backwash filter equipment, the manual backwash valve is opened to allow the inside of the filter tube to flow smoothly. Water enters through the inlet, passes through the filter tube, and flows out through the drain. Most of the dirt remains on the inner wall of the filter tube. When backwashing is required, the manual backwash valve is closed, shutting off the filter tube. Water enters through the inlet but is blocked by the manual backwash valve. Some of the water that has passed through the filter tube flows out and enters the filter housing cavity. It then enters the latter half of the manual backwash valve from the outer wall of the filter tube, cleaning the dirt attached to the inner wall of the filter tube. The first drive motor and the second drive motor are then started. The first drive motor drives the internal cleaning component to clean the inner wall of the filter tube, while the second drive motor drives the reciprocating screw to rotate, thereby moving the moving block back and forth. The scraper ring on the moving block scrapes and cleans the outer wall of the filter tube, cleaning both the inner and outer walls of the filter tube, improving the cleaning and decontamination effect. The waste is then discharged through the drain pipe, which is convenient, quick, and highly efficient.

[0011] Preferably, for cleaning the inner wall of the filter tube, the inner cleaning component includes a connecting rod fixedly mounted on the output shaft of the first drive motor, and a scraper adapted to the inner wall of the filter tube is fixedly mounted on the connecting rod. This accelerates the removal of stubborn stains.

[0012] Preferably, to clean the outer wall of the filter tube, evenly distributed bristles are fixedly installed on the inner side wall of the scraper ring, and the bristles are positioned to abut against the outer side wall of the filter tube. This improves cleaning efficiency.

[0013] Preferably, to accelerate stain removal, a steel plate fixedly connected to the scraper ring is fixedly installed on the moving block, and a rack is fixedly installed in the mounting groove. Several evenly distributed toothed blocks that abut against the sides of the steel plate are fixedly installed on the rack. Vibration is transmitted to the filter tube, accelerating the removal of stains from the filter tube.

[0014] Preferably, to reduce wear, the outer wall of the tooth block is chamfered, and the side of the steel sheet is chamfered. This reduces obstruction and lowers wear.

[0015] This backwash filter starts with a first drive motor and a second drive motor. The first drive motor drives the inner cleaning component to clean the inner wall of the filter tube, while the second drive motor drives the reciprocating screw to rotate, which in turn drives the moving block to move back and forth. This causes the scraper ring on the moving block to scrape and clean the outer wall of the filter tube, thus cleaning both the inner and outer walls of the filter tube and improving the cleaning and decontamination effect. The filter is then discharged through the drain pipe, which is convenient, fast, and highly efficient.

[0016] In this backwash filter, the moving block moves, which in turn moves the steel plate. As the steel plate moves, it comes into contact with the continuously uneven toothed block, which generates vibration. This vibration causes the scraper ring to vibrate as it moves, and the vibration is transmitted to the filter tube, accelerating the removal of dirt from the filter tube. Attached Figure Description

[0024] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0025] Example 1

[0026] This embodiment provides a horizontal manual backwash filter, such as Figure 1-5 As shown, the backwash filter includes a filter housing 2 fixedly mounted on a bracket 1 and an inlet 3 fixedly mounted on one end of the filter housing 2. A drain outlet 4 is fixedly mounted on the outer wall of the filter housing 2. A manual backwash valve 5 is rotatably mounted on the filter housing 2. A filter tube 6 is fixedly mounted inside the filter housing 2. A cleaning mechanism 7 for cleaning the inner and outer walls of the filter tube 6 is fixedly mounted on the filter housing 2. A drain pipe 8 is provided at the end of the filter housing 2 away from the inlet 3.

[0027] The cleaning mechanism 7 includes a sealing plate 71 fixedly installed on the filter housing 2 at one end away from the inlet 3, a drain pipe 8 fixedly installed on the sealing plate 71 and connected to the filter pipe 6, a first drive motor 72 fixedly installed on the sealing plate 71, the output shaft of the first drive motor 72 passing through the sealing plate 71 and extending into the filter pipe 6, and an inner cleaning component 73 fixedly installed on the output shaft of the first drive motor 72.

[0028] The cleaning mechanism 7 also includes a mounting groove 76 fixedly installed on the filter housing 2. A second drive motor 77 is fixedly installed on the outer wall of one end of the mounting groove 76. The output end of the second drive motor 77 extends through the mounting groove 76 and is fixedly installed with a reciprocating screw 78. A moving block 79 is slidably connected to the reciprocating screw 78. A scraper ring 711 sleeved on the outer wall of the filter tube 6 is fixedly installed on the moving block 79.

[0029] When in use, open the manual backwash valve 5 to allow the inside of the filter tube 6 to be unobstructed, and water enters through the inlet 3. After being filtered by the filter tube 6, the water flows out through the drain 4. Most of the dirt remains on the inner wall of the filter tube 6. When backwashing is required, close the manual backwash valve 5 to close the filter tube 6. Water enters through the inlet 3 but is blocked by the manual backwash valve 5. Some of the water filtered by the filter tube 6 flows out and enters the cavity of the filter housing 2. Then, it enters the rear half of the manual backwash valve 5 from the outer wall of the filter tube 6 to clean the dirt attached to the inner wall of the filter tube 6.

[0030] The first drive motor 72 and the second drive motor 77 are started. The first drive motor 72 drives the inner cleaning component 73 to clean the inner wall of the filter tube 6. At the same time, the second drive motor 77 drives the reciprocating screw 78 to rotate, thereby driving the moving block 79 to move back and forth. This causes the scraper ring 711 on the moving block 79 to scrape and clean the outer wall of the filter tube 6. This cleans both the inner and outer walls of the filter tube 6, improving the cleaning and decontamination effect. The waste is then discharged through the drain pipe 8, which is convenient, quick, and highly efficient.

[0031] Specifically, the internal cleaning component 73 includes a connecting rod 74 fixedly mounted on the output shaft of the first drive motor 72, and a scraper 75 adapted to the inner wall of the filter tube 6 is fixedly mounted on the connecting rod 74. In use, the connecting rod 74 rotates with the output rod of the first drive motor 72, driving the scraper 75 to scrape the inner wall of the filter tube 6, accelerating the removal of stubborn stains.

[0032] More specifically, the inner wall of the scraper ring 711 is fixedly equipped with evenly distributed bristles 712, which abut against the outer wall of the filter tube 6. During use, as the scraper ring 711 moves, the bristles 712 scrape the surface of the filter tube 6, improving cleaning efficiency.

[0033] Furthermore, a steel plate 710 fixedly connected to the scraper ring 711 is fixedly installed on the movable block 79, and a rack 713 is fixedly installed in the mounting groove 76. Several evenly distributed toothed blocks 714 that abut against the sides of the steel plate 710 are fixedly installed on the rack 713. In use, when the movable block 79 moves, it drives the steel plate 710 to move. When the steel plate 710 moves, it comes into contact with the continuously uneven toothed blocks 714, thereby generating vibration. This causes the scraper ring 711 to vibrate when it moves, and the vibration is transmitted to the filter tube 6, accelerating the removal of dirt from the filter tube 6.

[0034] Furthermore, the outer wall of the toothed block 714 is chamfered, and the side of the steel plate 710 is chamfered. In use, when the rack 713 moves, the side contacts the chamfered toothed block 714 through the curved edge, reducing obstruction and wear.

[0035] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
