Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of backwashing devices, and more specifically, to a backwashing device for sludge oil filtration. Background Technology
[0002] A backwashing device is a device used to clean water filter pipes or filters. It uses high-pressure water flow or reverse water flow to flush away dirt and impurities on the filter screen, thereby maintaining the filtration efficiency and lifespan of the water filter. It is widely used in water treatment, industrial filtration and other fields. It can be cleaned automatically or manually, avoiding the tedious and inconvenient manual cleaning required for traditional filters due to impurities clogging. It improves filtration efficiency and reduces maintenance costs. It is also widely used in sludge and oil filtration.
[0003] For example, Chinese patent disclosure: Backwashing device for rotary drum microfiltration machine, application number: CN201420263343.2, includes a dissolved air pump and a backwashing water pipe. The dissolved air pump is connected to the clear water tank. One end of the backwashing water pipe is connected to the dissolved air pump, and the other end extends to the top of the filter cartridge. Multiple backwashing nozzles are opened in the lower part of the portion of the backwashing water pipe above the filter cartridge. This backwashing device for rotary drum microfiltration machine mixes clear water and gas to form dissolved air water through the dissolved air pump. The gas blows oil off the filter screen, and the water can better wash the suspended particles, achieving a better washing effect on the filter screen, thereby ensuring the filtration effect of the filter cartridge.
[0004] However, in the above technical solutions, when backwashing the filter cartridge is required, the backwash liquid is usually sprayed onto the surface of the filter cartridge at a certain pressure and angle through a nozzle. The impact force of the liquid is used to wash away the dirt attached to the filter cartridge. However, since the position of the nozzle is fixed, it can only spray directly onto specific areas of the filter cartridge. This means that the cleaning range that the nozzle can cover is limited and cannot reach every corner of the filter cartridge. In particular, some hidden parts of the filter cartridge or areas that are difficult to reach by the nozzle spray angle can easily become cleaning dead spots. Utility Model Content

[0018] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.
[0019] like Figure 1 and Figure 2 As shown, a backwashing device for sludge oil filtration includes a device base 1, on which a filter cartridge 2 is mounted. A connecting pipe 3 and a water inlet pipe 4 are fixedly mounted on one side of the device base 1. A backwashing water pipe 5 is disposed between the connecting pipe 3 and the water inlet pipe 4. Several nozzles 6 are disposed on the side of the backwashing water pipe 5 near the filter cartridge 2. A drive assembly 7 is disposed on the side of the backwashing water pipe 5 away from the nozzles 6. A guide groove 8 is disposed on the side of the device base 1 near the drive assembly 7. A guide slider 9 is slidably disposed in the guide groove 8.
[0020] like Figure 3 As shown, in another embodiment of the present invention, the drive assembly 7 has a motor 701 fixedly mounted on the device base 1, the motor 701 is provided with a first rotating column 702, the first rotating column 702 is provided with a cam 703, and the cam 703 is provided with a second rotating column 704.
[0021] A first rotating ring 705 is rotatably mounted on the second rotating column 704, a push rod 706 is fixedly mounted on the first rotating ring 705, and a second rotating ring 707 is fixedly mounted on the push rod 706.
[0022] A pusher 708 is rotatably mounted on the second rotating ring 707;
[0023] When the backwash water pipe 5 needs to move back and forth, the motor 701 first rotates the first rotating column 702, which in turn drives the cam 703 to rotate. The cam 703 then drives the second rotating column 704, which in turn drives the first rotating ring 705 to rotate around the first rotating column 702. The first rotating ring 705 then drives the push rod 706 to move, which in turn drives the push column 708 to move via the second rotating ring 707. This causes the push column 708 to move back and forth, and the guide groove 8 and guide slider 9 guide the direction of movement of the push column 708. The push column 708 then drives the backwash water pipe 5 to move, thus causing the backwash water pipe 5 to move back and forth.
[0024] The working principle of this residual oil filtration backwashing device:
[0025] In use, when backwashing of the filter cartridge 2 is required, backwash liquid is introduced into the backwash water pipe 5 through the inlet pipe 4. Then, the backwash liquid in the backwash water pipe 5 is sprayed onto the filter cartridge 2 through the nozzle 6 to backwash the filter cartridge 2. At the same time, the motor 701 causes the first rotating column 702 to rotate, which in turn drives the cam 703 to rotate. The cam 703 drives the second rotating column 704, which in turn drives the first rotating ring 705 to rotate around the first rotating column 702. The first rotating ring 705 drives... The push rod 706 moves, and the push rod 706 drives the push column 708 to move through the second rotating ring 707, causing the push column 708 to reciprocate. The guide groove 8 and the guide slider 9 guide the movement direction of the push column 708. The push column 708 drives the backwash water pipe 5 to move, thereby causing the backwash water pipe 5 to reciprocate. The backwash water pipe 5 drives the nozzle 6 to reciprocate, which ensures that the backwash liquid evenly covers the entire cleaning area, avoids cleaning dead corners, and makes the backwash liquid more effective at acting on dirt, thereby improving cleaning efficiency and reducing cleaning time.
[0026] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. All obvious variations or modifications derived from the technical solutions of the present invention are still within the protection scope of the present invention.
