Description

Technical Field

[0001] The utility model relates to the technical field of filters, in particular to a laminated filter. Background Art

[0002] The laminated filter is composed of a large number of thin annular laminates overlapped and locked to form a cylindrical filter element. Each annular laminate has two sides, and many filter grooves are distributed on both sides. When water passes through it, the solid suspended matter and organic matter in the water are intercepted, thereby physically purifying the water. Because it can work accurately and stably under quite harsh conditions of use and rarely requires maintenance, it is widely used in irrigation, wastewater treatment, sewage regeneration, municipal water supply, water plants, large power plants, chemical companies and emergency filtration and other fields.

[0003] For example, the patent (CN210814270U) discloses a laminated filter, which states that "by adding a stepper motor and utilizing its forward and reverse rotation principle to transmit power to the rotating shaft, the rotating shaft then drives the rotating blades to reverse, thereby separating the laminates from the locked state, and at the same time avoiding the laminates from sticking to each other, so that the laminates can be filtered and cleaned."

[0004] When using the above technology, it was found that the following technical problems exist in the prior art: most traditional laminated filter devices are equipped with automatic backwashing devices. When used for a long time, some stubborn stains will inevitably adhere to them. Therefore, it is necessary to disassemble and clean the inside of them at intervals. However, the above device is not easy to disassemble, which reduces the cleaning efficiency, increases the labor intensity of workers, and reduces the practicality of the device. For this reason, we designed a laminated filter to provide another technical solution to the above technical problems. Utility Model Content

[0046] The use process of a laminated filter provided by the utility model is as follows: before filtering, first start the motor 19 so that the motor 19 drives the lifting screw 20 to rotate, and when the lifting screw 20 rotates, it drives the pressing plate 21 threadedly connected thereto to move along the axial direction of the lifting screw 20, so that the filter sheet 25 sleeved on the outside of the support frame 22 is pressed by the movement of the pressing plate 21, and then the sewage enters the interior of the fixed housing 1 through the water inlet pipe 4.
