Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a cylindrical filter cartridge and a wastewater filtration device. Background Technology

[0002] Existing wastewater filtration devices utilize high-speed rotating filter cartridges to generate powerful centrifugal force, rapidly separating solid particles, sediments, and other substances from the water, and then discharging the residue in a concentrated manner, thus achieving rapid and efficient wastewater treatment. However, in current wastewater filtration devices, when a large amount of dirt and sediment accumulates inside the filter cartridge, it easily clogs the cartridge walls, affecting the filtration effect. Furthermore, the filter cartridges are not integral, making subsequent maintenance very troublesome. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a straight cylindrical filter cartridge and sewage filtration device that is easy to install in an integrated inclined manner.

[0004] The purpose of this utility model can be achieved through the following technical solution: a straight cylindrical filter cylinder, including a cylindrical body and a front sealing plate and a rear sealing plate respectively disposed at both ends of the cylindrical body, wherein a plurality of hollowed-out filter holes are opened on the periphery of the cylindrical body, and a filter screen for covering the filter holes is provided inside the cylindrical body.

[0005] As a further embodiment of this invention, the filter holes include first filter holes and second filter holes spaced apart. Specifically, the first filter holes are regular polygons, and the second filter holes are circular.

[0006] This utility model also provides a sewage filtration device, including a filter cylinder, an inlet pipe, and an internal and external rinsing device. The filter cylinder is a straight-cylinder filter cylinder. The internal and external rinsing device includes an external rinsing pipe disposed on the outside of the filter cylinder and an internal rinsing pipe disposed on the inside of the straight-cylinder filter cylinder. The internal rinsing pipe and the inlet pipe are respectively disposed at both ends of the straight-cylinder filter cylinder. Several inlet branch pipes are connected to the inlet pipe for transporting sewage into the filter cylinder. The other end of the inlet pipe is connected to a sewage pump. Sewage flows into the cylinder through the inlet branch pipes, generating an impact force on the cylinder, causing the cylinder to rotate. Under the action of centrifugal force, water is thrown out from the first filter hole and the second filter hole. The residue after filtration by the filter screen falls from one end of the front sealing plate, thus realizing sewage filtration.

[0007] As a further embodiment of this utility model, the inlet pipe and the inner flushing pipe are connected by a sleeve, the cross-section of which is "I" shaped, and the ends of the inlet pipe and the inner flushing pipe are sealed by the sleeve.

[0008] As a further embodiment of this utility model, four external flushing branch pipes are connected to the external flushing pipe.

[0009] As a further embodiment of this utility model, the inner flushing pipe is connected to three inner flushing branch pipes.

[0010] As a further embodiment of this utility model, it also includes a flushing water pump, which is connected to an external flushing pipe, and the external flushing pipe and the internal flushing pipe are connected by a connecting pipe.

[0011] The beneficial effects of this utility model are: This utility model provides a straight cylindrical filter cartridge and sewage filtration device that are easy to install in an integrated tilt. It adopts an integrated straight cylindrical filter cartridge and washes the inside and outside of the filter cartridge by setting internal and external washing devices to ensure the cleanliness of the washing, improve the filtration efficiency, and extend the service life of the filter cartridge.
