Technical Field

[0001] This utility model relates to the field of high-concentration wastewater treatment in aquaculture, specifically a backwashing secondary filtration component for high-concentration wastewater from aquaculture. Background Technology

[0002] High-concentration wastewater treatment in livestock and poultry farming is a purification technology used to treat wastewater with high concentrations and complex compositions of pollutants generated during the livestock and poultry farming process. The secondary filtration component is the core device of the physical filtration unit in the livestock and poultry wastewater treatment system. It is used to further improve the wastewater purification efficiency and mainly targets the fine suspended solids, colloids and some dissolved pollutants that remain after pretreatment, ensuring that the water quality meets the requirements of subsequent biological or advanced treatment.

[0003] However, current secondary filtration components still have some shortcomings. The backwashing structure of existing secondary filtration components is not fully considered. When using secondary filtration components to treat high-concentration wastewater from aquaculture, if the backwashing structure is not fully considered, impurities on the surface of the internal filter components may cause microbial decay due to long-term retention, affecting the smooth operation of secondary filtration of wastewater, greatly shortening the replacement cycle of filter elements or filter media, causing certain economic losses, and making it inconvenient for staff to use the wastewater secondary filtration components. Summary of the Invention

A filter cartridge is disposed on the inner side of the body, and a support plate is disposed at the bottom of the filter cartridge. The support plate is fixedly connected to the inner wall of the body. The drain pipe is welded to the center of the support plate, and the top of the drain pipe is engaged with the bottom center of the filter cartridge. A connecting rod is fixedly connected to the outer wall of the bottom end of the drain pipe, and the end of the connecting rod is welded to the inner wall of the body. The sealing cover is disposed above the filter cartridge, and a filter element is disposed on the inner side of the filter cartridge. A cleaning assembly is disposed on the inner side of the filter element, and the cleaning assembly includes a drive motor, a rotating rod, a support, and a cleaning component.

[0006] Furthermore, a limiting ring engages with the upper part of the outer wall of the filter cartridge, and the limiting ring is fixedly connected to the inner wall of the machine body.

[0007] Furthermore, a cylindrical locking block is welded to the bottom of the filter cartridge, and the filter cartridge is engaged with the support plate through the cylindrical locking block, and holes are provided on the edge of the support plate.

[0008] Furthermore, a PLC controller is installed on the outside of the machine body, and a valve is installed on the inside of the sewage pipe.

[0009] Furthermore, a fixing strip is welded to the top of the machine body, and a sealing cover is connected to the machine body by the fixing strip, and a feed hopper is fixedly connected to the top of the sealing cover.

[0010] Furthermore, a locking ring is fixedly connected to the top of the filter element, and arc-shaped locking strips are welded to both the upper and lower sides of the locking ring. The locking ring is engaged with the filter cartridge and the sealing cover respectively through the arc-shaped locking strips.

[0025] In summary, this backwashing secondary filtration component for high-concentration aquaculture wastewater, based on... Figures 1-5The structure shown illustrates the process of treating high-concentration aquaculture wastewater using a secondary filtration assembly. First, the operator places the filter cartridge 2 inside the machine body 1, engaging the upper outer wall of the filter cartridge 2 with the limiting ring 3 fixed to the inner wall of the machine body 1. The cylindrical locking block 5 welded to the bottom of the filter cartridge 2 engages with the support plate 4, and the bottom center of the filter cartridge 2 engages with the top center of the drain pipe 6, thus completing the placement of the filter cartridge 2. Next, the operator places the filter element 12 inside the filter cartridge 2, engaging the arc-shaped locking strip 14 welded to the lower side of the locking ring 13 at the top of the filter element 12 with the top of the filter cartridge 2. Then, the operator engages the sealing cover 9 with the fixing strip 10 welded to the top of the machine body 1, and the sealing cover 9 engages with the arc-shaped locking strip 14 welded to the upper side of the locking ring 13.
