Description

Technical Field

[0001] The utility model relates to the technical field of sewage filtration, and particularly relates to a device for filtering and treating construction sewage. Background Art

[0002] During the construction process, sewage will inevitably be generated. This sewage generally contains liquid and small particulate solid impurities. The liquid may contain components that can pollute the environment. Therefore, it is necessary to separate the solid and liquid by filtration for the sewage, and then perform corresponding subsequent treatments on the liquid and the solid respectively.

[0003] Filtration is generally carried out using filter elements such as filter meshes, filter tubes or filter membranes. As the usage time increases, the small particulate solid impurities will be adsorbed on the filter element in the form of mud, causing the filter element to be blocked and its filtration performance to gradually decrease until it cannot meet the required filtration requirements.

[0004] To solve the above problems, the prior art generally adopts the method of regularly disassembling, cleaning or replacing the filter element to ensure the filtration performance. However, this method not only reduces the filtration efficiency but also causes a significant increase in cost, which is not conducive to long-term use. Content of the Utility Model

Second, it includes a filter pipe 20. A plurality of filter holes 21 are formed in the pipe wall of the filter pipe 20. The filter pipe 20 is arranged inside the box body 10. The liquid inlet chamber 12 is communicated with the inside of the filter pipe 20. The inside of the filter pipe 20 is communicated with the liquid discharge chamber 13 through all the filter holes 21. At least one end of the filter pipe 20 penetrates through the box body 10 to form a sewage discharge pipe 22. Third, it includes a sewage auger 30. The sewage auger 30 is arranged inside the filter pipe 20, and the diameter of the sewage auger 30 matches the inner diameter of the filter pipe 20.

[0030] A building sewage filtration and treatment device provided by the utility model divides the box body 10 into a liquid inlet chamber 12 and a liquid discharge chamber 13 by arranging a box body 10 and a partition 11, and is provided with a liquid inlet pipe 14 and a liquid discharge pipe 15. Sewage to be treated is introduced into the liquid inlet chamber 12 through the liquid inlet pipe 14, and the filtered liquid is discharged from the liquid discharge chamber 13 through the liquid discharge pipe 15. On this basis, by arranging a filter pipe 20 with a plurality of filter holes 21 formed in its pipe wall, the interior of the liquid inlet chamber 12 is communicated with the interior of the filter pipe 20, and the interior of the filter pipe 20 is communicated with the liquid discharge chamber 13 through all the filter holes 21, so that the sewage in the liquid inlet chamber 12 can be filtered through the filter pipe 20. The liquid after solid-liquid separation enters the liquid discharge chamber 13 through the filter holes 21, while the solids remain in the filter pipe 20. On this basis, at least one end of the filter pipe 20 penetrates through the box body 10 to form a sewage discharge pipe 22, and a sewage discharge auger 30 is arranged in the filter pipe 20. By rotating the sewage discharge auger 30, the solid impurities in the filter pipe 20 can be pushed to move axially along the filter pipe 20 until they are discharged from the sewage discharge pipe 22, and the inner wall of the filter pipe 20 can be scraped during the rotation of the sewage discharge auger 30, so as to scrape off the solid impurities adhered to the inner wall surface thereof, so as to ensure the filtering performance of the filter pipe 20. Through the mutual cooperation of the above features, the building sewage filtration and treatment device can effectively solve the problems that the existing devices for building sewage filtration need to be frequently disassembled, cleaned or replaced with filter elements, resulting in reduced filtration efficiency and increased filtration cost.

[0031] In order to further explain the connection structure between the filter pipe 20 and the liquid inlet chamber 12, a sewage inlet 23 is formed in the side wall of the filter pipe 20, and the size of the sewage inlet 23 is much larger than the size of the filter hole 21; the liquid inlet chamber 12 is communicated with the interior of the filter pipe 20 through the sewage inlet 23.

[0032] Preferably, in order to ensure the liquid inlet volume, the sewage inlet 23 extends axially along the filter pipe 20 and penetrates through both ends of the filter pipe 20; the inner side of the partition 11 is hermetically connected to the wall of the sewage inlet 23, and the outer side of the partition 11 is hermetically connected to the inner wall of the box body 10.

[0033] In order to optimize the filtering structure, the filter pipe 20 is horizontally arranged, and the sewage inlet 23 is arranged facing directly upward; two symmetrically arranged partitions 11 are formed by the outward extension of the wall of the sewage inlet 23.

[0035] Preferably, the liquid inlet pipe 14 is vertically arranged at the top of the box body 10 and points to the middle of the filter pipe 20.

[0036] To prevent the discharge of liquid from the sewage discharge pipe 22, a partition bin 16 is provided at the position of the sewage discharge pipe 22 in the box body 10. The partition bin 16 divides the sewage discharge pipe 22 into two sections; a partition piece 161 is detachably inserted into the partition bin 16, and the partition piece 161 can block the partition bin 16 to block the sewage discharge pipe 22.

[0037] To further explain the specific structure of the partition bin 16, the partition bin 16 is a bin body with a preset thickness. The thickness of the partition bin 16 matches the thickness of the partition piece 161, and the size of the partition piece 161 is larger than the inner diameter of the sewage discharge pipe 22; a jack 162 is opened on the side wall of the partition bin 16 for inserting the partition piece 161. When the partition piece 161 is inserted into the partition bin 16, the partition piece 161 blocks the sewage discharge pipe 22.

[0038] To enable the sewage discharge flow rate of the sewage discharge pipe 22 to be adjusted, a hydraulic telescopic rod 17 is provided on the box body 10. The push rod of the hydraulic telescopic rod 17 is connected to the partition piece 161 so that the partition piece 161 can be inserted into or pulled out of the jack 162.

[0039] To control the rotation of the sewage discharge auger 30, one end of the sewage discharge auger 30 away from the sewage discharge pipe 22 is connected with a servo motor 31. The servo motor 31 is located outside the box body 10 and is fixedly connected to the box body 10.
