Description

Technical Field

[0001] The utility model relates to the field of sewage filtration, and more specifically, to a filtration device which is convenient for replacing filter materials. Background Art

[0002] With the development of social modernization, the discharge of domestic sewage and industrial sewage is increasing day by day. These sewage need to be filtered and treated before being discharged into rivers, otherwise it will cause very serious pollution to the rivers.

[0003] The Chinese patent authorization announcement number: CN217041494U provides a sewage filtering device, which includes a shell, a top cover, a filter and a backwashing part; the filter is horizontally arranged in the shell, a water inlet and a slag outlet are arranged on the shell below the filter, a drain is arranged on the shell above the filter, the top cover is fixed to the top of the shell by fasteners, the backwashing part is connected to the lifting device arranged on the top cover, the backwashing part is connected to the cleaning pipe, the cross-section of the water outlet end of the backwashing part is an arc-shaped structure, and the water outlet end of the backwashing part is provided with a plurality of spray holes. The cross-section of the water outlet end of the backwashing part in the utility model is an arc-shaped structure, so when the cleaning pipe is filled with water, the water flow sprayed from the water outlet end of the backwashing part can better cover the filter; at the same time, the backwashing part is also connected to the lifting device, and when the lifting device drives the backwashing part to move up and down, the flushing position and angle of the water flow on the filter will also change, so the filter can be flushed at multiple angles, and the efficiency and effect of backwashing are better.

[0004] In the above-mentioned patent, a lot of impurities will accumulate on the surface and inside of the filter mechanism after long-term use. Since the connection between the filter mechanism and the shell is relatively fixed, it is inconvenient to clean and replace the filter mechanism, which has limitations in use. Utility Model Content

[0032] Embodiment 1:

[0033] See also Figure 1-5 A filtering device that is easy to replace filter materials includes a box body 1, an installation frame 22 is fixedly connected inside the box body 1, a connecting plate 23 is fixedly connected inside the installation frame 22, a rotating shaft 27 is fixedly connected above the connecting plate 23, and a No. 1 clamping block 24 and a No. 2 clamping block 25 are rotatably connected to the outer wall of the rotating shaft 27, the lower part of the No. 1 clamping block 24 is located inside the No. 2 clamping block 25, one side of the No. 1 clamping block 24 and the No. 2 clamping block 25 are fixedly connected with a spring 26, the end of the spring 26 is fixedly connected to the top of the connecting plate 23, a clamping block 21 is clamped between the No. 1 clamping block 24 and the No. 2 clamping block 25, and the top of the clamping block 21 is fixedly connected to a fixed frame 19.

[0034] In this embodiment, if the adsorption plate 2 in the fixed frame 19 is to be replaced, the user can pull the fixed frame 19 upwards. At this time, the clamping block 21 below the fixed frame 19 will squeeze the inner walls of the No. 1 clamping block 24 and the No. 2 clamping block 25. At this time, the No. 1 clamping block 24 and the No. 2 clamping block 25 will rotate above the connecting plate 23, and the distance between the ends of the No. 1 clamping block 24 and the No. 2 clamping block 25 will increase. At this time, the spring 26 will undergo elastic deformation and contraction. As the gap between the No. 1 clamping block 24 and the No. 2 clamping block 25 gradually increases, the clamping block 21 clamped between the No. 1 clamping block 24 and the No. 2 clamping block 25 will lose its extrusion, and the user can take the fixed frame 19 out of the inside of the box body 1.

[0035] Embodiment 2:

[0036] See also Figure 1-5 The interior of the fixed frame 19 is clamped with an adsorption plate 2, a fixed groove 11 and a slide groove 12 are opened on the upper part of the interior of the box body 1, a filter screen 16 is arranged inside the box body 1, and a limit block 17 is fixedly connected to the outside of the filter screen 16, and the limit block 17 and the slide groove 12 are slidably connected. The top of the box body 1 is rotatably connected with a top plate 13, and a fixed block 14 is fixedly connected to the bottom of the top plate 13. The fixed block 14 is clamped in the interior of the fixed groove 11, and handles 18 are fixedly connected to both sides of the top of the filter screen 16. The filter screen 16 is located above the fixed frame 19, and the adsorption plate 2 is clamped inside the fixed frame 19. The interior of the box body 1 is fixedly connected with a collecting cover 28, and the bottom end of the collecting cover 28 is fixedly connected with a water outlet pipe 29, and the water outlet pipe 29 is fixedly connected to the bottom of the interior of the box body 1. A water inlet 15 is opened in the middle of the top plate 13.

[0037] In this embodiment, after the pipe is connected to the water inlet 15, the sewage to be filtered will enter the interior of the box 1 from the water inlet 15, and then the filter 16 will filter the impurities with larger volume in the sewage. After the sewage passes through the filter 16, the adsorption plate 2 will adsorb the impurities with smaller volume that pass through the filter 16 in the sewage. After being adsorbed by the adsorption plate 2, the sewage will pass through the adsorption plate 2 along the collection cover 28 and finally flow out from the outlet pipe 29. If the user needs to clean the impurities accumulated on the surface of the filter 16, the user can rotate the top plate 13, pull the handle 18 and pull the filter 16 out of the interior of the box 1.

[0038] The working principle of the utility model is: when the user is in use, after connecting the pipe to the water inlet 15, the sewage to be filtered will enter the interior of the box body 1 from the water inlet 15, and then the filter screen 16 will filter the impurities with larger volume in the sewage. After the sewage passes through the filter screen 16, the adsorption plate 2 will adsorb the impurities with smaller volume that pass through the filter screen 16 in the sewage. After being adsorbed by the adsorption plate 2, the sewage will pass through the adsorption plate 2 along the collection cover 28 and finally flow out from the outlet pipe 29. If the user needs to clean the impurities accumulated on the surface of the filter screen 16, the user can rotate the top plate 13, pull the handle 18 and pull the filter screen 16 out of the interior of the box body 1.

[0039] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
