Description

Technical Field

[0001] This utility model relates to a rotating disc filter box. Background Technology

[0002] In dyeing and printing washing machines, the water in the tank needs to be continuously filtered and circulated. Generally, a drum filter box is used. Water containing lint and impurities enters the drum filter box, is filtered by the cylindrical filter screen, and is then reintroduced into the washing tank. Although the drum filter box rotates continuously, lint will accumulate on the filter screen, causing it to become clogged. The filter screen needs to be disassembled and cleaned frequently. During the cleaning process, the filtration system must be paused, affecting the washing process. Moreover, disassembly and cleaning are very tedious and greatly increase labor costs. Utility Model Content

[0003] To overcome the above-mentioned shortcomings, this utility model provides a rotating disc filter box that avoids lint clogging the filter screen, reduces the labor costs of disassembly and cleaning, and ensures the smooth operation of water washing filtration.

[0004] To achieve this objective, the structure adopted by this utility model is as follows: a rotating disc filter box, including a box body, in which a rotating filter disc is installed. A partition is installed below the rotating filter disc to divide the box body into a sewage area and a clean water area. The sewage area is provided with a water inlet. The rotating shaft in the center of the rotating filter disc is connected to a worm gear reducer through a belt conveyor. The clean water area is provided with a spray pipe. The nozzle of the spray pipe faces the rotating filter disc. The spray pipe is connected to a water pump through a pipe. The water pump is connected to a water pumping pipe provided in the clean water area.

[0005] The filter disc has a disc-shaped structure with a filter screen on the surface, and the top of the partition plate is an arc shape that matches the bottom of the filter disc.

[0006] A collection tray is installed next to the filter disc, and a collection box is installed on the outside of the box body. The collection box is connected to the sewage area, and one side of the collection tray is connected to the collection box. A filter screen is installed inside the collection box.

[0007] A support frame is provided at the bottom of the box.

[0008] The water pump is connected to a water outlet pipe.

[0009] A lid is provided on the top of the box.

[0010] Its beneficial effects are: the structure of this utility model is reasonable and ingenious. After the sewage passes through the filter disc to remove floating hair, it enters the clean water area. The floating hair adhering to the filter disc falls onto the collection tray under the impact of the spray pipe, avoiding the accumulation of floating hair on the filter disc and causing blockage. It also eliminates the need to disassemble the machine to clean the floating hair. Attached Figure Description

[0014] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0015] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used solely for the convenience of describing this utility model and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0016] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components; a fixed connection can be welding or adhesive bonding. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0017] like Figure 1 , Figure 2The rotating disc filter shown includes a housing 1, inside which a rotating filter disc 5 is installed. A rotating shaft is located at the center of the rotating filter disc 5, and the shaft is connected to a worm gear reducer 6 via a belt conveyor. Driven by the motor and the worm gear reducer 6, the rotating filter disc 5 rotates. The rotating filter disc 5 has a disc-shaped structure with a filter screen surface, capable of filtering floating hair from wastewater. A partition 14 is located below the rotating filter disc 5, dividing the lower part of the housing 1 into a wastewater zone and a clean water zone. The top of the partition 14 is arc-shaped to fit the rotating filter disc 5, filling in areas not covered by the rotating filter disc 5. A water inlet pipe 3 is installed in the wastewater zone, connecting to the outlet of the washing machine's water tank, introducing wastewater into the housing 1. After being filtered by the rotating filter disc 5, the wastewater enters the clean water zone, while floating hair adheres to the rotating filter disc 5. A water pump 7 is connected to a water suction pipe 8 in the clean water zone. The pump extracts water from the clean water zone and sends some of the water back into the washing machine through the water outlet pipe 9. The other part of the water flows into a spray pipe 10 located in the clean water zone. The spray pipe 10 has multiple nozzles arranged on it, which are directed towards the filter disc 5. The pressurized water flow washes away the floating hair on the filter disc 5, and the floating hair falls into the collection tray 11 located next to the filter disc 5. This avoids the problem of floating hair accumulating on the filter disc 5 and causing blockage. In addition, the filter disc 5 does not need to be removed for cleaning, ensuring the smooth operation of the water flow.

[0018] The collection tray 11 is set at an angle. The lower side of the collection tray 11 is connected to the box 1. An opening groove is provided at the connection, which leads to the collection box 12 set outside the box 1. A filter screen 13 is provided on the top of the collection box 12. Floating hair is collected on the filter screen 13 for easy cleaning. The filtered water flows back to the sewage area from below the box 12.

[0019] The top of the housing 1 is open, and a cover 4 is provided at the opening to prevent water splashed from the spray pipe 5 from flowing outside the housing 1 and to keep the outside of the disc filter box clean.

[0020] A support 2 is provided at the bottom of the box 1 to match the height of the water tank of the washing machine and to prevent the water level in the tank from being too high and causing sewage to overflow from the box 1.

[0021] Both the sewage zone and the clean water zone are equipped with ball valves at the bottom, making it convenient to empty the water in the tank 1 for routine maintenance.

[0022] This novel structural design is reasonable and ingenious. By adding a spray pipe inside the box, the filter discs 5 can be cleaned in real time, which saves and simplifies the daily maintenance procedures of the filter box, ensures smooth operation of filtration for a long time, and improves the working efficiency of the filtration device.

[0023] Based on the above description and inspired by this utility model, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
