Description

Technical Field

[0001] The utility model belongs to the technical field of sewage treatment, and in particular relates to municipal sewage treatment equipment. Background Art

[0002] With the rapid development of urbanization, a lot of urban sewage will be generated, which requires processing and treating these sewage for secondary use to reduce the waste of water resources. At present, municipal sewage contains more impurities. During the sewage treatment process, the filter element needs to be cleaned and maintained to maintain the filtering efficiency, but the manual cleaning method not only affects the filtering efficiency, but also has high labor intensity. A sewage treatment device for municipal water supply and drainage is disclosed in the Chinese utility model patent with publication number CN220309832U. A connecting rod mechanism is used to control the synchronous flipping movement of the first filter screen and the second filter screen, and the first conical cavity and the second conical cavity structure are combined to realize the backwashing of the first filter screen and the second filter screen, thereby ensuring the filtering effect of the filter screen. However, this method of only flushing the filter screen with water flow cannot effectively clean up the debris on the filter screen, and not only the cleaning effect is poor, but also the cleaning efficiency is low. Therefore, it is urgent to design a municipal sewage treatment device that can efficiently clean the filter assembly. Utility Model Content

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] Reference Figure 1-2 , a municipal sewage treatment equipment comprises a treatment box 1 with an open top, a water inlet pipe 2 is connected to the right end side wall of the treatment box 1, and a water outlet pipe 3 is connected to the left end side wall of the treatment box 1, two first filter screens 4 and a second filter screen 5 are installed in the treatment box 1 from right to left in sequence, the two first filter screens 4 are vertically slidably installed in the treatment box 1, the second filter screen 5 is fixedly connected to the treatment box 1, the top ends of the two first filter screens 4 are respectively fixedly connected to the lifting components, and the two lifting components are respectively fixedly connected to the outer side walls of the treatment box 1, and the top of the treatment box 1 is respectively provided with a first cleaning component for cleaning the two first filter screens 4, and the second cleaning component for cleaning the second filter screen 5 is provided above the second filter screen 5.

[0020] In this embodiment, slide grooves are provided on the front and rear side walls of the treatment box 1 at positions corresponding to the two side edges of the first filter screen plate 4, and the two side edges of the first filter screen plate 4 are slidably installed in the slide grooves respectively. The setting of the slide grooves can not only provide a guide for the lifting and lowering of the first filter screen plate 4, but also improve the sealing between the first filter screen plate 4 and the side wall of the treatment box 1, thereby preventing sewage from passing through the gap between the first filter screen plate 4 and the side wall of the treatment box 1, thereby affecting the filtering effect.

[0021] In this embodiment, the lifting assembly includes two support bases 6, the two support bases 6 are respectively fixedly connected to the bottom of the front and rear side walls of the processing box 1, and the two support bases 6 are respectively fixedly connected with first hydraulic telescopic rods 7, and the top ends of the two first hydraulic telescopic rods 7 are fixedly connected with lifting plates 8, and the bottom ends of the lifting plates 8 are fixedly connected to the top ends of the first filter screen plates 4 through fixed connecting rods 9. The lifting and lowering of the lifting plates 8 and the first filter screen plates 4 can be controlled by controlling the extension and retraction of the first hydraulic telescopic rods 7.

[0022] In this embodiment, the first cleaning assembly includes two brush rollers 10 respectively arranged on both sides of the top of the first filter screen plate 4, the brush rollers 10 are rotatably installed between the front and rear side walls of the processing box 1, and one end of the brush roller 10 penetrates the side wall of the processing box 1 and is fixedly connected to the output shaft of the driving motor 11. During the rising and falling process of the first filter screen plate 4, the driving motor 11 can be turned on to drive the brush roller 10 to rotate, so as to clean the first filter screen plate 4. The driving motor 11 is a servo motor, and its rotation direction can be adjusted according to the lifting state of the first filter screen plate 4. Taking the brush roller 10 on the left side of the first filter screen plate 4 as an example, when the first filter screen plate 4 rises, the driving motor 11 drives the brush roller 10 on the left side to rotate clockwise, and when the first filter screen plate 4 falls, the driving motor 11 drives the brush roller 10 on the left side to rotate counterclockwise, so as to achieve the best cleaning effect.

[0023] In this embodiment, the two brush rollers 10 located on both sides of the first filter screen plate 4 are symmetrically arranged, and the bristles on the two brush rollers 10 are in close contact with the surface of the first filter screen plate 4 .

[0024] In this embodiment, the second cleaning assembly includes a gantry 12 located above the second filter screen plate 5, the gantry 12 is fixedly connected to the top of the side wall of the treatment box 1, and the lower surface of the crossbeam of the gantry 12 is connected to a scraper 14 through a second hydraulic telescopic rod 13, and the scraper 14 is in close contact with the side of the second filter screen plate 5 close to the water inlet pipe 2. The lifting and lowering of the scraper 14 can be controlled by controlling the extension and retraction of the second hydraulic telescopic rod 13, so that the scraper 14 is used to clean the dirt on the second filter screen plate 5.

[0025] In this embodiment, one side of the scraper 14 is in close contact with the second filter screen plate 5 , and the other side of the scraper 14 is two intersecting inclined surfaces, so that the top and bottom ends of the scraper 14 can clean the surface of the second filter screen plate 5 .

[0026] In this embodiment, the bottom of the cavity located on the right side of the second filter screen plate 5 and the two first filter screen plates 4 in the treatment box 1 is connected to a conical cavity 15 for collecting sludge. A sewage outlet 16 is provided at the bottom end of the conical cavity 15. A sewage outlet 16 is provided at the sewage outlet 16. When the sludge in the conical cavity 15 reaches a certain amount, the sewage outlet door can be opened to discharge the sludge.

[0027] In this embodiment, a plurality of support columns 17 are fixedly disposed at the bottom of the processing box 1 for reliably supporting the processing box 1 .

[0028] When the utility model is actually working, the cleaning work of the two first filter screen plates 4 needs to be performed alternately, so as to avoid the two first filter screen plates 4 being lifted at the same time to affect the sewage filtering effect.

[0029] The above description is only a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any slight modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
