Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a sewage treatment floating matter removal device. Background Technique

[0002] Sewage treatment is a process of purifying sewage to meet the water quality requirements for discharging it into a certain water body or reusing it. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, and catering. During the sewage treatment process, a large amount of floating matter needs to be centrally cleaned on the surface of the sewage.

[0003] For example, the utility model with the application number CN202221810398.1 discloses a floating matter cleaning device for urban sewage treatment, including a sliding frame and a slideway assembly. The slideway assembly is installed at the lower positions of both ends of the sliding frame. A fixed frame is fixedly installed in the middle position at the lower end of the sliding frame, and a filter screen is fixedly installed inside the fixed frame. A scraping and sewage cleaning component cooperating with the filter screen is movably installed on the upper part of the sliding frame. The slideway assembly includes a first slide rail, a splicing clamping rail, and a second slide rail. The first slide rail is spliced and installed on the outer surface of one end of the splicing clamping rail; an electric caster is used to drive a sliding seat, so that a slider drives a splicing scraping strip to slide on the sliding frame, thereby enabling a row brush to clean the blocking substances on the filter screen, avoiding the blocking phenomenon of the filter screen, making the cleaning operation more convenient. With the setting of the scraping and sewage cleaning component, the maintenance and cleaning operation of the floating matter cleaning device for urban sewage treatment is more labor-saving and convenient to use.

[0004] The current situation similar to the above application still has the following deficiencies:

[0005] During the sewage treatment process, it is difficult to clean the surface of the filter screen part. When there is too much floating matter, it is easy to cause blockage, affecting the sewage treatment effect.

[0006] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and a sewage treatment floating matter removal device is proposed. Content of the Utility Model

Specific embodiments

[0022] The following further describes in detail the embodiments of the present utility model with reference to the accompanying drawings and examples. The following examples are used to illustrate the present utility model, but cannot be used to limit the scope of the present utility model.

[0023] As Figure 1 and Figure 2 shown, a floating matter removal device for sewage treatment includes an upper separation box 1. A feed inlet 2 is opened at the front end of the upper separation box 1. A rotating plate 3 is rotatably connected inside the upper separation box 1 at the rear end of the feed inlet 2. A baffle 4 is slidably connected inside the front end of the rotating plate 3. A spring 5 is sleeved at the rear end of the baffle 4. Pressing buckles 6 are integrally connected to the left and right ends of the baffle 4. The baffle 4 is elastically connected to the rotating plate 3 through the spring 5. The baffle 4 is slidably connected to the upper separation box 1 through the pressing buckles 6 and the limit grooves 19. The limit grooves 19 are inclined. When the baffle 4 is pushed, it will drive the connected rotating plate 3 to flip accordingly, so that the pressing buckles 6 slide upward along the inclined limit grooves 19. The baffle 4 is restricted by the rearward inclined limit grooves 19 and compresses the spring 5 inward, partially contracting the baffle 4 into the rotating plate 3, thus facilitating the flipping of the filter screen 8 to enter.

[0024] As Figure 2 and Figure 3 shown, a rotating shaft 7 is rotatably connected at the front end inside the upper separation box 1. A filter screen 8 is installed outside the rotating shaft 7. The rotation of the rotating shaft 7 drives the rotation of the three filter screens 8 at its outer end, thereby replacing the blocked filter screens 8, avoiding the blockage of the filter screens 8 and affecting the sewage treatment effect, and also facilitating the centralized collection and cleaning of the floating matter collected on the surface of the filtered filter screens 8. A slag discharge port 9 is opened at the rear end on the upper side of the upper separation box 1. A lower separation box 10 is provided at the lower end of the upper separation box 1. A discharge port 11 is opened at the front end of the lower separation box 10. Limit grooves 19 are opened on both sides of the upper separation box 1 where the baffle 4 is located.

[0025] As Figure 1 and Figure 4As shown in the figure, an electrical box 12 is installed on the right side of the front end of the lower separation box 10. Chutes 13 are provided on the left and right sides of the rear end of the lower separation box 10. Rollers 14 are rotatably connected inside the chutes 13. A hydraulic rod 15 is provided in the middle of the front end of the lower separation box 10. The rear end of the hydraulic rod 15 is connected to a scraper 16. Driven by the hydraulic rod 15, the scraper 16 slides along the direction of the chute 13 to push the floating objects collected inside the lower separation box 10 for centralized collection, facilitating cleaning. A sinking groove 17 is provided in the middle of the rear end of the lower separation box 10. A lifting plate 18 is slidably connected inside the sinking groove 17. A corresponding lifting member is provided at the lower end of the lifting plate 18 inside the sinking groove 17. After being pushed by the scraper 16 onto the surface of the lifting plate 18 for collection, the lifting plate 18 is lifted by the lifting member at the bottom end and protrudes from the slag discharge port 9, facilitating cleaning by the staff.

[0026] In summary, as Figures 1 to 4 shown, when using the sewage treatment floating object removal device, first, sewage enters the upper separation box 1 through the feed port 2. The water flow is filtered through the filter screen 8. The floating objects are blocked on the surface of the filter screen 8. The sewage passes through the filter screen 8 and is discharged from the discharge port 11. When a certain amount of floating objects accumulates on the surface of the filter screen 8, the rotating shaft 7 rotates driven by electrical components. The filter screen 8 for filtration follows the rotation. One filter screen 8 at the lower end flips to the baffle 4. At this time, the baffle 4 is squeezed, and the connected rotating plate 3 is driven to flip accordingly. Then, the buckle 6 slides upward along the inclined limiting groove 19. The baffle 4 is restricted by the backward inclined limiting groove 19 and compresses the spring 5 inward, contracting part of the baffle 4 into the rotating plate 3, thus facilitating the entry of the filter screen 8. Correspondingly, when the baffle 4 slides a certain distance, it disengages from the contact with the filter screen 8. On the one hand, it slides to the bottom end under the action of gravity. On the other hand, it is ejected by the reverse force of the spring 5, causing the baffle 4 to support the filter screen 8 at the bottom end. There is a limiting block protruding from the upper separation box 1 at the lower end of the rotating plate 3, preventing the rotating plate 3 from rotating beyond the position of the limiting block, ensuring the stability of the placement of the filter screen 8. While the filter screen 8 at the bottom end rotates driven by the rotating shaft 7, the filter screen 8 in the filtering position also rotates to the upper end, and then the floating objects blocked on its surface are overturned into the lower separation box 10. When a certain amount is collected, the hydraulic rod 15 pushes the scraper 16 to slide, pushing the floating objects inside the lower separation box 10 onto the lifting plate 18 inside the sinking groove 17. The lifting plate 18 is pushed out of the slag discharge port 9 by the lifting device at the bottom end of the lifting plate 18, thus facilitating the collection and cleaning by the staff. In this way, the use process of the entire sewage treatment floating object removal device is completed.

Many modifications and variations are obvious to those of ordinary skill in the art.
