Description

Technical Field

[0001] The utility model relates to the field of sludge discharging devices, and more specifically, to a sludge discharging device for sewage treatment. Background Art

[0002] The sludge scraper in the sludge discharging device for sewage treatment is a machine for discharging and cleaning sludge, and is used in circular sedimentation tanks with larger diameters in urban sewage treatment plants, waterworks, and industrial wastewater treatment to remove the sludge settled at the bottom of the tank and skim the floating scum on the tank surface.

[0003] During the operation of the sludge scraper, sludge substances are likely to accumulate and adhere to the outer wall surface of the rubber sludge scraping panel. Excessive external attachments will affect its sludge scraping efficiency, which is not conducive to ensuring the use efficiency of the rubber sludge scraping panel. And it is time-consuming and laborious to clean it manually in a circular sedimentation tank with a large diameter, and the efficiency is low. Therefore, it is necessary to design a sludge discharging device for sewage treatment with a self-scraping wall function to solve the above problems. Aiming at the problems existing in the prior art, the purpose of the utility model is to provide a sludge discharging device for sewage treatment, which can drive the rubber sludge scraping panel to slide up and down in the slightly inclined scraping strip by an electric push rod, so that the pointed angle block contacts the front and rear wall surfaces of the rubber sludge scraping panel, and scrape off the attachments on the outer wall surface of the rubber sludge scraping panel, which is conducive to ensuring the use efficiency of the rubber sludge scraping panel and avoiding the problem that its external attachments are too many and affect its sludge scraping efficiency. Summary of the Utility Model

[0004] To solve the above problems, the utility model adopts the following technical solutions.

[0005] A sludge discharging device for sewage treatment includes a central shaft column. Both the left and right ends of the central shaft column are fixedly connected with horizontal strip hollow rods. The upper inner wall of the horizontal strip hollow rod is fixedly connected with an electric push rod. The lower end of the horizontal strip hollow rod is fixedly connected with a plurality of slightly inclined scraping strips. The inner end of the slightly inclined scraping strip is slidably connected with a rubber sludge scraping panel. The output end of the electric push rod is fixedly connected with a strip plate. Both the front and rear ends of the slightly inclined scraping strip are fixedly connected with electric rotating shafts. The output ends of the electric rotating shafts are fixedly connected with inner inclined scraping strips. One end of the inner inclined scraping strip far away from the electric rotating shaft is fixedly connected with a pointed angle block.

[0006] Further, the lower end of the strip plate extends into the slightly inclined scraping strip and is connected with the upper end of the rubber sludge scraping panel.

[0007] Further, the two inner inclined scraping strips are respectively opposite to the front and rear sides of the corresponding rubber sludge scraping panel, and the rubber sludge scraping panel contacts the pointed angle block.

[0008] Further, the upper end of the rubber sludge scraping panel is fixedly connected with a compression spring, and the upper end of the compression spring is connected with the strip plate.

[0009] Further, inner vertical sliding grooves are symmetrically formed at the front and rear ends of the slightly inclined scraping bar, and inner sliding blocks are fixedly connected to the front and rear ends of the rubber mud scraping panel.

[0010] Further, the inner sliding blocks are slidably connected with the inner vertical sliding grooves, and the rubber mud scraping panel is in contact with the sewage separation tank.

[0011] Further, a sludge discharge port is formed in the middle of the lower inner wall of the sewage separation tank, and the sludge discharge port is directly below the central shaft column. Beneficial effects

[0012] Compared with the prior art, the advantages of the present utility model are as follows:

[0013] (1) In this solution, the central shaft column drives a plurality of horizontal bar hollow rods to displace annularly therein, effectively separating sewage and sludge. The electric push rod is used to drive the rubber mud scraping panel to slide up and down in the slightly inclined scraping bar. During the sliding process, the electric rotating shaft is used to drive the inner inclined mud scraping bar to rotate inward, so that the pointed corner blocks thereon contact the front and rear wall surfaces of the rubber mud scraping panel, scraping off the attachments on the outer wall surface of the rubber mud scraping panel, which is beneficial to ensuring the use efficiency of the rubber mud scraping panel and avoiding the problem that its scraping efficiency is affected due to excessive external attachments.

[0014] (2) When the rubber mud scraping panel slides up and down in the slightly inclined scraping bar, the inner vertical sliding groove can be used to contact the inner sliding block to provide a vertical guiding force for the rubber mud scraping panel, making its displacement process smoother.

[0015] (3) At the same time, a compression spring is also arranged between the strip-shaped plate under the electric push rod and the rubber mud scraping panel. The compression spring can make the rubber mud scraping panel always contact the lower bottom wall of the sewage separation tank. After the lower part of the rubber mud scraping panel wears a certain distance, the tightness of the contact between the two can still be ensured, ensuring its scraping efficiency and not easily generating gaps.
