Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a wastewater treatment device with a filtration structure. Background Technology

[0002] Wastewater treatment aims to remove pollutants from water through physical, chemical, or biological methods to meet discharge standards or reuse requirements, thereby protecting the environment and human health.

[0003] Publication No. CN222400518U discloses a wastewater treatment device with a filtration structure, belonging to the field of wastewater treatment technology. It mainly includes an outer cylinder, inside which a filter cartridge with an open top is fixed. A partition is fixed to the outer wall of the filter cartridge, dividing the interior of the outer cylinder into upper and lower layers: an upper feeding layer and a lower filtration layer. A feeding pipe is fixed to the upper side of the outer wall of the outer cylinder, communicating with the interior of the feeding layer. A water outlet pipe is fixed to the lower side of the outer wall of the outer cylinder, communicating with the interior of the filtration layer. A sludge outlet pipe is fixed to the lower end of the outer cylinder, communicating with the lower end of the filter cartridge. A scraper shaft is rotatably connected between the two ends of the filter cartridge, and several scrapers are fixed to the outer wall of the scraper shaft, the scrapers being adapted to rotate under external drive. This wastewater treatment device with a filtration structure achieves the effect of cleaning the filter cartridge.

[0004] The aforementioned patent addresses the issue that the filter pores of existing wastewater treatment equipment are easily clogged by impurities, leading to a decrease in filtration efficiency. However, the existing technical solution uses a scraper to remove impurities from the inner wall of the filter cartridge. The scraper can only remove impurities from the surface of the inner wall of the filter cartridge, and some impurities will still remain inside the filter pores. The cleaning of impurities is not thorough enough, and the cleaning effect is poor. Therefore, a wastewater treatment device with a filtration structure is proposed to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a wastewater treatment device with a filtration structure, which has the advantage of good cleaning effect. It solves the problem that existing wastewater treatment devices can only scrape off impurities from the inner wall surface of the filter cartridge, leaving some impurities inside the filter holes, resulting in insufficient cleaning and poor cleaning effect.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a wastewater treatment device with a filtration structure, comprising an outer cylinder, wherein a filtration and cleaning structure is provided on the outer cylinder;

[0007] The filtration and cleaning structure includes a storage cylinder fixedly installed inside the outer cylinder, a filter cylinder fixedly installed at the bottom of the storage cylinder, an installation cylinder fixedly installed at the top of the outer cylinder and connected to the storage cylinder, an electric telescopic rod fixedly installed inside the installation cylinder, an installation plate fixedly installed at the bottom of the electric telescopic rod, a vacuum machine fixedly installed on the lower surface of the installation plate, an adsorption box connected to the vacuum machine fixedly installed on the lower surface of the vacuum machine, a scraper fixedly installed on the lower surface of the adsorption box, an air filter cylinder inside the adsorption box, a sewage inlet pipe fixedly installed on the surface of the filter cylinder extending to the outside of the outer cylinder, and a clean water outlet pipe fixedly installed on the outer surface of the outer cylinder.

[0008] Furthermore, the filter cartridge surface is provided with filter holes, and the number of filter holes is multiple and evenly distributed on the surface of the filter cartridge.

[0009] Furthermore, the adsorption box is circular in shape, and a plurality of strip-shaped adsorption holes are formed on the side surface of the adsorption box.

[0010] Furthermore, two rubber sealing rings are fixedly installed on the side surface of the adsorption box, and the rubber sealing rings are in contact with the inner surface of the filter cartridge, with the strip-shaped adsorption hole located between the two rubber sealing rings.

[0011] Furthermore, there are two sewage inlet pipes and two clean water outlet pipes. The sewage inlet pipe is connected to the inside of the filter cylinder, and the clean water outlet pipe is connected to the inside of the outer cylinder.

[0012] Furthermore, the diameter of the storage tube is the same as the diameter of the filter tube, and the storage tube and the filter tube are connected.

[0013] Furthermore, both the mounting plate and the scraper are compatible with the storage cylinder and the filter cylinder.

[0014] Furthermore, the lower surface of the adsorption box is provided with a threaded hole, and a threaded connecting plate that matches the threaded hole is fixedly installed on the upper surface of the scraper.

[0015] Furthermore, the bottom of the filter cartridge extends to the outside of the outer cylinder, and the bottom of the filter cartridge has an open structure and is threaded with a sealing cap.

[0016] Compared with the prior art, the technical solution of this application has the following beneficial effects:

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1 to 3 This embodiment of a wastewater treatment device with a filtration structure includes an outer cylinder 1, on which a filtration and cleaning structure is provided. The filtration and cleaning structure includes a receiving cylinder 2 fixedly installed inside the outer cylinder 1, a filter cylinder 3 fixedly installed at the bottom of the receiving cylinder 2, the diameter of the receiving cylinder 2 being the same as the diameter of the filter cylinder 3, and the receiving cylinder 2 and the filter cylinder 3 being connected. An installation cylinder 4, connected to the receiving cylinder 2, is fixedly installed at the top of the outer cylinder 1. An electric telescopic rod 5 is fixedly installed inside the installation cylinder 4, and an installation plate 6 is fixedly installed at the bottom of the electric telescopic rod 5. A vacuum machine 7 is fixedly installed on the lower surface of the vacuum machine 7. An adsorption box 8 connected to the vacuum machine 7 is fixedly installed on the lower surface of the adsorption box 8. A scraper 9 is fixedly installed on the lower surface of the adsorption box 8. An air filter cylinder 10 is provided inside the adsorption box 8. A sewage inlet pipe 11 extending to the outside of the outer cylinder 1 is fixedly installed on the surface of the filter cylinder 3. A clean water outlet pipe 12 is fixedly installed on the outer surface of the outer cylinder 1. There are two sewage inlet pipes 11 and two clean water outlet pipes 12. The sewage inlet pipe 11 is connected to the inside of the filter cylinder 3, and the clean water outlet pipe 12 is connected to the inside of the outer cylinder 1.

[0024] The filter cylinder 3 has multiple filter holes 13 on its surface, which are evenly distributed on the surface of the filter cylinder 3.

[0025] It should be noted that the adsorption box 8 is circular in shape, and a number of strip-shaped adsorption holes 14 are opened on the side surface of the adsorption box 8. Two rubber sealing rings 15 are fixedly installed on the side surface of the adsorption box 8. The rubber sealing rings 15 are in contact with the inner surface of the filter cylinder 3, and the strip-shaped adsorption holes 14 are located between the two rubber sealing rings 15.

[0026] The mounting plate 6 and scraper 9 are both compatible with the storage cylinder 2 and the filter cylinder 3.

[0027] It should be noted that the lower surface of the adsorption box 8 is provided with a threaded hole 16, and the upper surface of the scraper 9 is fixedly installed with a threaded connecting plate 17 that is compatible with the threaded hole 16. The bottom of the filter cylinder 3 extends to the outside of the outer cylinder 1, and the bottom of the filter cylinder 3 has an open structure and is threadedly connected with a sealing cap 18.

[0028] The working principle of the above embodiments is as follows:

[0029] Wastewater enters the filter cylinder 3 through the wastewater inlet pipe 11. The filter holes 13 on the surface of the filter cylinder 3 intercept suspended solids and particulate impurities. The preliminarily purified water flows into the outer cylinder 1 and is discharged from the outer cylinder 1 through the clean water outlet pipe 12 on the surface of the outer cylinder 1. The electric telescopic rod 5 drives the mounting plate 6 and the vacuum machine 7 to move downwards as a whole, which in turn drives the adsorption box 8 and the scraper 9 into the interior of the filter cylinder 3. The scraper 9 moves against the inner wall of the filter cylinder 3, scraping off the attached impurities and pushing them to the bottom of the filter cylinder 3. At the same time, the vacuum machine 7 is activated, generating negative pressure through the strip-shaped adsorption holes 14 on the side of the adsorption box 8, adsorbing and filtering. After cleaning the impurities in hole 13, the electric telescopic rod 5 drives the adsorption box 8 and scraper 9 to move upward and return to the inside of the storage cylinder 2. The open structure at the bottom of the filter cylinder 3 is sealed by the threaded sealing cover 18. After cleaning, the sealing cover 18 needs to be opened manually to discharge the accumulated impurities. At the same time, the scraper 9 can be removed from the adsorption box 8 to clean and maintain the air filter cylinder 10 and impurities inside the adsorption box 8. The rubber sealing ring 15 can ensure that there is no leakage when the strip adsorption hole 14 is working, improve the adsorption effect, and prevent sewage from entering the adsorption box 8 through the strip adsorption hole 14.
