[0002] A backwash disc filter is a precision filtration device that uses grooved plastic discs stacked together to remove impurities from water through a combination of surface interception and depth filtration, and has an automatic backwashing function.

[0003] However, existing backwash disc filters often lack a support frame that is easy to install and fix, and often require fixing bolts and tools for installation, which is time-consuming and laborious, causing inconvenience during use. Therefore, there is an urgent need for a backwash filter for water pollution treatment to solve the above problems. Utility Model Content

[0004] In order to overcome the above-mentioned technical problems, the purpose of this utility model is to provide a backwash filter for water pollution treatment, so as to solve the problem mentioned in the background art that the existing backwash disc filters often do not have a support frame that is easy to install and fix, and often require fixing bolts and tools for installation.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a backwash filter for water pollution treatment, comprising a backwash disc filter body, a support structure, and a clamping structure. The support structure includes a fixed frame, with three support rods fixedly connected to the left and right ends of the top of the fixed frame, and a connecting rod fixedly connected between two of the support rods. Support seats are fixedly connected to the four bottom corners of the fixed frame. The clamping structure includes two fixed rings, which are rotatably connected by hinges. A fixed plate is fixedly connected to the left side of each fixed ring, and a rotating rod is rotatably connected to the bottom of the fixed plate. A threaded rod is fixedly connected to the top of the rotating rod, and a handle is threadedly connected to the threaded rod.

[0006] Preferably, the position of the support rod corresponds to the left and right ends of the inlet pipe, outlet pipe and drain pipe of the backwash disc filter body.

[0007] Preferably, the four connecting rods are interconnected to form a U-shape, and the four connecting rods are fixedly connected to the six support rods.

[0008] Preferably, a rubber pad is fixedly connected to the bottom of the support base, and the bottom surface of the rubber pad has a plurality of protrusions.

[0009] Preferably, the bottom of the grip is fixedly connected to a limiting seat, the limiting seat being a T-shaped cylinder, and the bottom end of the limiting seat engaging with the top of the top fixing plate.

[0010] Preferably, the limiting seat has a circular hole in the middle, and the diameter of the circular hole is larger than the diameter of the threaded rod.

[0011] Preferably, the inner wall of the fixing ring is fixedly connected to a second rubber pad, and the inner wall of the second rubber pad is provided with an uneven pattern.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This backwash filter for water pollution treatment is equipped with a support structure. Support rods support the left and right ends of the inlet pipe, outlet pipe, and sewage pipe of the backwash disc filter body. Connecting rods are welded to the support rods, increasing the support strength and improving safety and stability during use. A support base supports the fixed frame. Rubber pads increase the friction between the support base and the ground, and the raised points on the bottom of the rubber pads increase the contact area between the rubber pads and the ground, improving stability during support. The support structure supports the backwash disc filter body and evenly distributes the support pressure, providing high support strength, good anti-slip effect, and improved stability during support, making it easy to use.

[0013] 2. This backwash filter for water pollution treatment is equipped with a clamping structure. The pipe of the backwash disc filter body is placed on the fixing ring. The fixing ring is rotated by the hinge to cover the pipe. The rotating rod is rotated to position the rotating rod inside the fixing plate. The handle is rotated to drive the limiting seat to rotate, causing the limiting seat to move downward and lock into the fixing plate, thereby fixing the position of the fixing plate. The pipe is clamped by two fixing rings. The uneven surface of the rubber pad increases the friction between the fixing ring and the pipe, and the elasticity of the rubber pad prevents the fixing ring from squeezing the pipe and causing damage to the pipe surface. The clamping structure can fix the inlet pipe, outlet pipe and sewage pipe of the backwash disc filter body. The installation and fixing are convenient and quick, without the need for fixing bolts and tools, and are easy to use. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-5 This utility model provides an embodiment of a backwash filter for water pollution treatment, comprising a backwash disc filter body 1, a support structure 2, and a clamping structure 3. The support structure 2 includes a fixed frame 21, with three support rods 22 fixedly connected to the left and right ends of the top of the fixed frame 21, and a connecting rod 23 fixedly connected between two support rods 22. Support seats 24 are fixedly connected to the four bottom corners of the fixed frame 21. The clamping structure 3 includes two fixed rings 31, which are rotatably connected by hinges 33. A fixed plate 32 is fixedly connected to the left side of the fixed rings 31, and a rotating rod 34 is rotatably connected to the bottom of the fixed plate 32. A threaded rod 35 is fixedly connected to the top of the rotating rod 34, and a handle 36 is threadedly connected to the threaded rod 35.

[0018] Furthermore, the position of the support rod 22 corresponds to the left and right ends of the water inlet pipe, water outlet pipe and sewage discharge pipe of the backwash disc filter body 1, and the support rod 22 supports the left and right ends of the water inlet pipe, water outlet pipe and sewage discharge pipe of the backwash disc filter body 1.

[0019] Furthermore, the four connecting rods 23 are interconnected to form a U-shape, and the four connecting rods 23 are fixedly connected to the six support rods 22. The connecting rods 23 are welded to the support rods 22 by welding. The connecting rods 23 improve the support strength of the support rods 22, thereby improving the safety and stability during use.

[0020] Furthermore, a rubber pad 25 is fixedly connected to the bottom of the support base 24. The bottom surface of the rubber pad 25 is provided with several protrusions. The protrusions on the bottom surface of the rubber pad 25 can increase the contact area between the rubber pad 25 and the ground, thereby improving the stability during support.

[0021] Furthermore, the bottom of the grip 36 is fixedly connected to the limiting seat 37, which is a T-shaped cylinder. The bottom end of the limiting seat 37 is engaged with the top of the fixing plate 32. Rotating the grip 36 causes the grip 36 to drive the limiting seat 37 to rotate, causing the limiting seat 37 to move downward and engage with the fixing plate 32.

[0022] Furthermore, a circular hole is provided in the middle of the limiting seat 37, and the diameter of the circular hole is larger than the diameter of the threaded rod 35. The circular hole in the middle of the limiting seat 37 prevents the limiting seat 37 from interfering with the movement of the threaded rod 35.

[0023] Furthermore, a rubber pad 38 is fixedly connected to the inner wall of the fixing ring 31. The inner wall of the rubber pad 38 is provided with an uneven pattern. The uneven surface of the rubber pad 38 can increase the friction between the fixing ring 31 and the pipe, and the elasticity of the rubber pad 38 can prevent the fixing ring 31 from squeezing the pipe and causing damage to the pipe surface.

[0024] Working Principle: During use, the support rod 22 supports the left and right ends of the inlet pipe, outlet pipe, and drain pipe of the backwash disc filter body 1. The connecting rod 23 is welded to the support rod 22, increasing the support strength of the support rod 22 and improving safety and stability during use. The support base 24 supports the fixed frame 21. The rubber pad 25 increases the friction between the support base 24 and the ground, and the protrusions on the bottom of the rubber pad 25 increase the contact area between the rubber pad 25 and the ground, improving stability during support. The support structure 2 supports the backwash disc filter body 1 and evenly distributes the support pressure, providing high support strength, good anti-slip effect, improved stability during support, and ease of use. The pipe of the disc filter body 1 is placed on the fixing ring 31. The fixing ring 31 is rotated by the hinge 33 so that it covers the pipe. The rotating rod 34 is rotated so that it is located inside the fixing plate 32. The handle 36 is rotated so that it drives the limiting seat 37 to rotate, causing the limiting seat 37 to move downward and engage with the fixing plate 32, thereby fixing the position of the fixing plate 32. The pipe is clamped by the two fixing rings 31. The uneven surface of the rubber pad 38 increases the friction between the fixing ring 31 and the pipe, and the elasticity of the rubber pad 38 prevents the fixing ring 31 from squeezing the pipe and causing damage to the pipe surface. The clamping structure 3 can fix the inlet pipe, outlet pipe and sewage pipe of the backwash disc filter body 1. The installation and fixing are convenient and quick, without the need for fixing bolts and tools, and are easy to use.

[0025] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
