Description

Technical Field

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

[0002] Existing wastewater filtration devices utilize a high-speed rotating filter cartridge to generate strong centrifugal force, rapidly separating solid particles, sediments, and other substances from the water in the wastewater, and then discharging the residue in a concentrated manner, thereby achieving rapid and efficient wastewater treatment. However, current wastewater filtration devices typically use simple conical filter cartridges with a small angle, resulting in slow residue discharge and easy clogging of the cartridge walls, thus affecting the filtration effect. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a spiral flow guiding cone filter cartridge and a sewage filtration device.

[0004] The objective of this utility model can be achieved through the following technical solution: a spiral flow-guiding conical filter cartridge, comprising a conical cylinder and a front sealing plate and a rear sealing plate respectively disposed at both ends of the cylinder, wherein a plurality of perforated filter holes are opened on the periphery of the cylinder, and a filter screen for covering the filter holes is disposed inside the cylinder, and a flow guide plate is also disposed inside the cylinder. By setting the flow guide plate, it is easier to form a stronger water flow, which allows waste to flow out faster, guides the residue to flow away towards the large diameter end of the cylinder, prevents clogging, and improves filtration efficiency.

[0005] As a further embodiment of this utility model, the guide plate is arranged spirally along the inner wall of the cylinder.

[0006] As a further embodiment of this utility model, the filter holes include first filter holes and second filter holes that are spaced apart.

[0007] As a further embodiment of this utility model, the first filter hole and the second filter hole are elliptical holes of different sizes.

[0008] This utility model also provides a sewage filtration device, including a filter cylinder, an inlet pipe, and internal and external flushing devices. The filter cylinder is a spiral-guided conical filter cylinder. The internal and external flushing devices include an external flushing pipe disposed on the outside of the spiral-guided conical filter cylinder and an internal flushing pipe disposed on the inside of the spiral-guided conical filter cylinder. The internal flushing pipe and the inlet pipe are respectively disposed at both ends of the spiral-guided conical filter cylinder. Several inlet branch pipes are connected to the inlet pipe for conveying sewage into the filter cylinder. Specifically, 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 filter holes. The residue after filtration by the filter screen falls from the large-diameter end of the cylinder, thus achieving sewage filtration.

[0009] 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.

[0010] As a further embodiment of this utility model, four external flushing branch pipes are connected to the external flushing pipe.

[0011] As a further embodiment of this utility model, the inner flushing pipe is connected to three inner flushing branch pipes.

[0012] 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.

[0013] The beneficial effects of this utility model are as follows: This utility model provides a spiral flow-guiding conical filter cartridge and a sewage filtration device. It adopts a conical filter cartridge and also sets a guide plate inside the filter cartridge. By setting the guide plate, it is easy to form a stronger water flow, which can make waste flow out faster and guide the residue to flow away towards the large diameter end of the cartridge, preventing blockage and improving filtration efficiency. Furthermore, by setting an internal and external flushing device, the inside and outside of the filter cartridge are flushed to ensure the cleanliness of the flushing, improve filtration efficiency, and extend the service life of the filter cartridge.
