Description

Technical Field

[0001] This utility model relates to a sewage treatment device, specifically a sewage treatment tank. Background Technology

[0002] Wastewater treatment refers to the process of purifying wastewater to meet the water quality requirements for discharge into a water body or for reuse. It is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscaping, medical care, and catering. Wastewater treatment typically uses wastewater treatment tanks.

[0003] Existing wastewater treatment tanks typically include a support structure, a tank body fixed to the support structure, a filter screen mechanism fixed to the inner wall of the tank, a stirring mechanism installed on the tank body and located inside the tank, an inlet pipe component connected to the upper end of the tank body's side wall, and a drain pipe component connected to the lower end of the tank body's side wall. When using existing wastewater treatment tanks, flocculants are usually added first to coagulate impurities in the wastewater. After coagulation, the impurities are filtered through the filter screen mechanism and then discharged through the drain pipe component. However, the coagulated impurities remain on the filter screen mechanism. Over time, the accumulated impurities can clog the filter screen mechanism, affecting wastewater filtration and severely impacting wastewater treatment efficiency. Summary of the Invention

[0004] To address the aforementioned shortcomings in the existing technology, this utility model aims to provide a sewage treatment tank to improve sewage treatment efficiency.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A sewage treatment tank includes a support mechanism, a tank body fixed on the support mechanism, a filter screen mechanism fixed on the inner wall of the tank body, a stirring mechanism installed on the tank body and located inside the tank body, a sewage inlet pipe component connected to the upper end of the side wall of the tank body, a drain pipe component connected to the lower end of the side wall of the tank body, and also includes an annular diverter mechanism fixed on the upper end of the inner wall of the tank body and connected to the sewage inlet pipe component, a spiral conveying mechanism connected to the lower end of the filter screen mechanism, a drain pipe component connected to the bottom of the spiral conveying mechanism, and a scraper mechanism fixed on the lower end of the stirring mechanism for scraping impurities on the filter screen mechanism, wherein the stirring mechanism is located above the filter screen mechanism, and the annular diverter mechanism is located above the filter screen mechanism.

[0006] As a limitation of this utility model, it also includes a plurality of waterproof vibrators fixed at the bottom of the filter screen mechanism.

[0007] As a further limitation of this utility model, the annular diverter mechanism includes an annular tube component, and multiple diverter components are spaced and connected on the annular tube component.

[0008] As a further definition of this utility model, the drain pipe component includes a first drain pipe component, a drain shut-off valve disposed on the first drain pipe component, a secondary filter component detachably connected to the first drain pipe component, and a second drain pipe component detachably connected to the secondary filter component.

[0009] As a further limitation of this utility model, the stirring mechanism includes a drive mechanism fixed to the top of the tank, a stirring shaft rotatably connected to the tank and located inside the tank, and a plurality of stirring blades fixed at intervals along the length of the stirring shaft.

[0010] As another limitation of this utility model, the filter screen mechanism is a funnel-shaped filter screen.

[0011] As a further limitation of this utility model, the scraper mechanism includes a plurality of inclined scrapers fixed on the lower end of the stirring mechanism, the plurality of inclined scrapers being located above the filter screen mechanism and in contact with the filter screen mechanism.

[0012] As a further definition of this utility model, the inclined scraper includes an inclined scraper body and a silicone scraper strip fixed on the inclined scraper body near the filter screen mechanism.

[0013] By adopting the above-mentioned technical solution, the beneficial effects achieved by this utility model compared with the prior art are as follows: (1) This utility model adopts a structure combining a support mechanism, a tank, a filter screen mechanism, a stirring mechanism, a sewage inlet pipe component, a sewage outlet pipe component, an annular diverter mechanism, a spiral conveying mechanism, a sewage outlet pipe component, and a scraper mechanism. The annular diverter mechanism allows sewage to fall onto the filter screen mechanism from multiple locations. The filter screen mechanism can filter the sewage. The scraper mechanism can scrape the filtered impurities on the filter screen mechanism. Under the action of the spiral conveying mechanism, the filtered impurities can be discharged to the outside of the tank, which can reduce the accumulation of impurities and blockage of the filter screen mechanism, thereby effectively improving the efficiency of sewage treatment.

[0014] (2) The present invention is equipped with a waterproof vibrator and a funnel-shaped filter screen. When the waterproof vibrator vibrates, it can loosen the impurities that fall on the filter screen mechanism, which can facilitate the scraper mechanism to scrape the impurities on the filter screen mechanism. When the waterproof vibrator vibrates, it can cause the scraped impurities to move into the screw conveyor mechanism so that the screw conveyor mechanism can discharge the impurities, which can improve the effect of the present invention in discharging impurities and further improve the efficiency of sewage treatment.

[0015] (3) The structure of the annular diverter mechanism in this utility model is simple and the manufacturing cost is low. Multiple diverter components are connected and arranged on the annular pipe component at intervals. Sewage can flow into the filter screen mechanism through multiple diverter components. The filter screen component can filter sewage better and improve the filtration efficiency of sewage.

[0016] (4) The drainage pipe component of this utility model has a secondary filter component, which can perform secondary filtration on the water after it has been filtered by the filter screen mechanism, thereby improving the quality of sewage treatment.

[0017] (5) In this utility model, the multiple oblique scrapers on the scraper mechanism can scrape impurities more efficiently. The oblique scrapers are equipped with silicone scraper strips to prevent damage to the filter screen mechanism when the oblique scrapers scrape impurities.

[0018] In summary, this utility model has a reasonable structure, is convenient to use, and is highly practical. During use, the filter screen mechanism filters wastewater, the scraper mechanism scrapes away the filtered impurities on the filter screen, and the screw conveyor mechanism discharges the filtered impurities to the outside of the tank, reducing the accumulation of impurities and clogging of the filter screen mechanism, thereby effectively improving the efficiency of wastewater treatment. This utility model is suitable for use in wastewater treatment. Attached Figure Description
