Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to an ultrafiltration machine with a spiral flow-guiding conical filter cartridge. Background Technology

[0002] Existing wastewater drum filters utilize the powerful centrifugal force generated by the high-speed rotating filter cylinder to rapidly separate solid particles, sediments, and other substances from the water in wastewater, and then discharge the residue in a concentrated manner, thus achieving rapid and efficient wastewater treatment. However, in current centrifugal filtration equipment, when a large amount of dirt and sediment accumulates inside the filter cylinder, it easily clogs the cylinder wall, affecting the filtration effect. Later maintenance requires disassembling the entire machine, which is very complex and cumbersome. Furthermore, wastewater only passes through the filter cylinder once, and the machine's filtration efficiency gradually decreases over time. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an ultrafiltration machine with a spiral flow guiding conical filter cartridge, which is beneficial to improving the filtration effect of wastewater.

[0004] The objective of this utility model can be achieved through the following technical solution: An ultrafiltration machine with a spiral-guided conical filter cartridge, comprising a main housing, a drum filter device, and an internal and external rinsing device; the main housing is provided with a filter chamber and a wastewater chamber, and a drainage chamber is provided below the filter chamber; the drum filter device includes a conical cylinder and a front sealing plate and a rear sealing plate respectively disposed at both ends of the cylinder, the cylinder rotating relative to the main housing, the cylinder having several perforated filter holes on its periphery, a filter screen for covering the filter holes being provided inside the cylinder, and a guide plate being provided inside the cylinder, the guide plate flowing along the cylinder... The internal wall arrangement facilitates a stronger water flow, allowing waste to flow out more quickly. A water inlet pipe is located at the center of the rear sealing plate, connected to several branch pipes. The water inlet pipe transports wastewater into the cylinder. The front sealing plate has a slag discharge port located within the wastewater tank. The internal and external flushing devices include an external flushing pipe for flushing the outer surface of the cylinder and an internal flushing pipe for flushing the inner surface of the cylinder. By setting up these internal and external flushing devices, the inner and outer sides of the filter cylinder are flushed, ensuring thorough cleaning, improving filtration efficiency, and extending the filter cylinder's service life and the equipment's continuous operation cycle.

[0005] As a further embodiment of this utility model, the guide plate is spirally arranged 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, and an extra-large elliptical drain outlet is adopted to accelerate the discharge of filtered water and improve filtration efficiency.

[0008] 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.

[0009] As a further embodiment of this invention, the external flushing pipe is connected to external flushing branch pipes facing the outer side of the cylinder. Specifically, four external flushing branch pipes are connected to the external flushing pipe.

[0010] As a further embodiment of this invention, the inner flushing pipe is connected to an inner flushing branch pipe facing the inner side of the cylinder. Specifically, the inner flushing pipe is connected to three inner flushing branch pipes.

[0011] As a further embodiment of this utility model, a flushing water pump is also included. The flushing water pump is connected to the outer flushing pipe, and the outer flushing pipe and the inner flushing pipe are connected by a connecting pipe. Specifically, the outer flushing pipe is connected to the flushing water pump, which is placed in the drainage chamber to draw water, facilitating simultaneous cleaning of the inside and outside of the filter cartridge. Simultaneously, it increases pressure to ensure thorough cleaning, improve filtration efficiency, and extend the service life of the filter cartridge.

[0012] As a further embodiment of this utility model, a secondary filtration assembly is provided between the filter chamber and the drainage chamber. The water in the filter chamber is filtered a second time through the secondary filtration assembly, thereby further improving the quality of the filtered water.

[0013] As a further embodiment of this utility model, the secondary filtration assembly includes a filter drawer disposed within the main housing, and the filter drawer contains filter cotton. Specifically, the filter drawer has several through holes for further filtration using the filter cotton, and is designed as a pull-out drawer, making installation simple and convenient, facilitating filter cotton replacement, and simplifying subsequent maintenance.

[0014] As a further embodiment of this utility model, the wastewater tank is provided with baffles that are inclined towards each other, and the bottom of the wastewater tank is provided with a wastewater outlet. The inclined baffles help the residue to accumulate in the middle, making it convenient to discharge. The wastewater outlet is located at the bottom of the wastewater tank, which avoids the problem of traditional machines having wastewater outlets on the side, resulting in water accumulation and the formation of a "stinky ditch".

[0015] As a further embodiment of this utility model, four buffer feet are installed at the bottom of the main housing, which can reduce resonance caused by machine operation and extend the service life of the machine.

[0016] The beneficial effects of this utility model are as follows: This utility model provides an ultrafiltration machine with a spiral-guided conical filter cartridge. It adopts a guide-type conical filter cartridge with an ultra-large taper design, and also includes a guide plate inside the cartridge. This creates a stronger rotating water flow when the cartridge rotates, allowing wastewater and filter residue to flow out more quickly. By incorporating internal and external flushing devices, the filter cartridge is flushed both inside and out, ensuring thorough cleaning, improving filtration efficiency, and extending the service life of the filter cartridge and the continuous operation cycle of the equipment. The entire filter cartridge adopts an integrated design, making installation and disassembly convenient and significantly reducing subsequent maintenance costs. The design of a two-layer drum filter device further enhances the filtration effect of wastewater. Attached Figure Description
