Description

Technical Field

[0001] The invention belongs to the field of filtration technology, and specifically refers to a thermoplastic molding type single-filter bidirectional filter element device. Background Art

[0002] Fluid filtration and purification refers to the removal of suspended matter, particulate matter, organic matter, microorganisms and other impurities in the fluid through physical or chemical means to achieve the purpose of purifying water quality or fluid media. This technology is widely used in industrial production, environmental protection, drinking water treatment and other fields.

[0003] Traditional fluid filtration devices have certain limitations in processing efficiency. Many existing water treatment equipment adopts a single filtering method, and its filtering effect is often unsatisfactory and the processing efficiency is low. In addition, some filtration devices need to replace consumable filter elements after long-term operation, which not only increases the operating cost, but also affects the continuous operation ability of the equipment.

[0004] Other equipment needs to regularly add consumable filter materials to maintain the filtering effect during operation, which is not only cumbersome to operate, but also increases the complexity of operation management. What is more inconvenient is that some equipment needs to be shut down for backwashing, which not only affects production efficiency, but may also cause secondary pollution of water quality. At the same time, existing backwashing devices are often time-consuming and labor-intensive, further increasing the operating cost and maintenance difficulty of the equipment. Summary of the invention

[0005] In order to solve the above-mentioned problems, the present invention proposes a thermoplastic molding single-filter bidirectional filter element device.

[0006] The technical scheme adopted by the present invention is as follows: The present invention provides a thermoplastic molded single-filter bidirectional filter element device, including a filter chamber, a filter cap is provided at the upper end of the filter chamber, the side wall of the filter cap is connected to a main water inlet pipe, the upper end of the filter chamber is sleeved with a main water outlet pipe, a supporting filter plate is provided at the bottom end of the inner wall of the filter chamber, the inner top end of the filter chamber is connected to an internal water distribution pipe, a floating plate is hinged on the side wall of the main water outlet pipe, a float is provided at one end of the floating plate, a drain pipe is provided at the inner top end of the filter chamber, a trough body is provided on the side wall of the drain pipe, the top end of the filter chamber is connected to a sewage valve, the side wall of the main water outlet pipe is connected to one end of an inner water outlet pipe, the other end of the inner water outlet pipe is connected to an intermediate water collector, a water inlet is provided on the side wall of the main water outlet pipe, and a baffle is provided on the inner wall of the main water outlet pipe.

[0007] Furthermore, a filter chamber 1 is provided above the supporting filter plate, the filter chamber 1 is provided with filter material, and a filter chamber 2 is provided below the supporting filter plate.

[0008] Furthermore, the sewage valve is arranged above the drainage pipe.

[0009] Furthermore, one end of the floating plate is lifted and lowered in the drainage pipe.

[0010] Furthermore, the water inlet is arranged in the filter cap.

[0011] Furthermore, the upper end of the inner water outlet pipe is arranged in the filter cap.

[0012] Furthermore, the main water inlet pipe is externally connected to a water pump.

[0013] Furthermore, the baffle is arranged above the water inlet, and the baffle is arranged below the intersection of the inner water outlet pipe and the main water outlet pipe.

[0014] The beneficial effects achieved by the present invention using the above structure are as follows: (1) This application has a two-way filtering function per unit area and has an excellent filtering effect.

[0015] (2) The coordinated use of filter chamber 1 and filter chamber 2 increases the filtration area and filtration path, thereby improving the overall filtration efficiency. At the same time, the setting of the supporting filter plate in filter chamber 2 further enhances the filtration effect, ensuring that the water quality is purer.

[0016] (3) When the impurities in the filter chamber accumulate to a certain extent, the pressure in the filter chamber is released by opening the sewage valve. The water pressure lifts the float plate, thereby blocking the internal water distribution pipe and preventing new water from entering the filter chamber. This design not only simplifies the sewage discharge process, but also realizes the self-cleaning of the filter chamber through physical means, reducing the frequency and difficulty of manual maintenance.
