Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment equipment, in particular to a filtering device at the input end of a sewage treatment pump. Background Art

[0002] Wastewater treatment is a complex process involving multiple technologies and regulations designed to remove pollutants from wastewater to protect the environment and public health.

[0003] Wastewater treatment technologies can be categorized into three types: physical, biological, and chemical. Physical methods primarily separate insoluble substances from wastewater through physical processes, such as gravity separation, centrifugation, reverse osmosis, and flotation. Biological methods utilize the metabolic functions of microorganisms to decompose and oxidize organic matter in wastewater into inorganic substances. Commonly used methods include activated sludge and biofilm processes. Chemical methods treat or recover dissolved or colloidal substances in wastewater through chemical reactions. Commonly used methods include coagulation, neutralization, redox, and ion exchange.

[0004] Regardless of the method, a sewage treatment pump is required to extract the sewage. Considering that impurities in the sewage may damage the structure of the treatment pump and may also accumulate inside, reducing the sewage treatment efficiency, a filtering device is usually set at the input end of the treatment pump to pre-treat the sewage. Traditional pre-treatment filtering equipment is inconvenient to disassemble and clean, and there is also the problem of poor filtering effect. Therefore, a filtering device at the input end of the sewage treatment pump is proposed. Utility Model Content

[0006] In order to achieve the above-mentioned purpose of good flexibility and easy cleaning, the utility model provides the following technical solution: a filtering device at the input end of a sewage treatment pump, comprising an outer frame, a guide cylinder arranged on the side of the outer frame, a filtering assembly arranged inside the outer frame, and a connecting assembly arranged on the inner side of the guide cylinder;

[0007] The filter assembly includes a filter outer frame inserted into the outer frame, a limit frame arranged on the inner wall of the outer frame, a plug-in slot opened on the side of the limit frame, a plurality of threaded slots opened on the inner wall of the limit frame, a support frame fixedly installed on the inner wall of the limit frame, a guide turbofan rotatably connected to the side of the support frame, a fixing hole opened on the outer wall of the limit frame, a limit cylinder slidably connected to the inside of the fixing hole, a plurality of limit sliders slidably connected to the inside of the limit cylinder, a locking spring fixedly installed on the side of one end of the limit slider, and a filter plate slidably connected to the inner wall of the outer frame.

[0008] The connecting assembly includes a fixed cylinder slidably connected to the inside of the guide cylinder, a fixed ring threadedly connected to the outside of the fixed cylinder, a plurality of positioning notches opened on the side of the guide cylinder, a positioning block inserted into the positioning notches, and a locking screw threadedly connected to the inside of the positioning block.

[0009] The frame wall of the filter outer frame is an L-shaped square structure. A filter screen cover is arranged inside the filter outer frame, and one side of the frame wall of the filter outer frame is embedded in the interior of the plug-in slot.

[0010] The frame wall of the filter outer frame is provided with a plurality of limiting perforations, and a slidably connected positioning pad is provided inside the limiting perforations, and one end of the limiting slider close to the plug-in slot is inserted into the positioning pad.

[0011] A threaded fixing screw is provided inside the threaded slot, and the bottom of the fixing screw abuts against the top surface of the positioning pad. A second layer of filter screen is provided inside the filter plate.

[0012] The limit slider is a T-shaped cylindrical structure, and the two ends of the positioning spring are fixedly installed with different limit sliders respectively. The inner wall of the outer frame is provided with a plurality of positioning jacks used in conjunction with the limit sliders.

[0013] The side surface of the outer frame is provided with a plurality of positioning slots for use with the positioning blocks, and the inner side walls of the positioning slots are provided with threaded holes for use with locking screws.

[0015] Compared with the prior art, the present invention provides a filtering device at the input end of a sewage treatment pump, which has the following beneficial effects:

[0016] 1. The filter device at the input end of the sewage treatment pump is installed by respectively embedding the filter outer frame and the limit frame from the front and rear sides of the outer frame, then putting the positioning pad on the top of the limit slider, and then inserting the assembly of the limit slider, the positioning spring and the limit cylinder into the interior of the threaded slot, and then using the fixing screw to screw into the interior of the threaded slot.
