Description

Technical Field

[0001] The utility model relates to the technical field of wastewater treatment, in particular to a wastewater treatment device for sodium hypochlorite production. Background Art

[0002] Sodium hypochlorite is a widely used disinfectant and bleaching agent with strong oxidizing and bactericidal properties. It usually appears in the form of an aqueous solution with a slightly yellowish color and a pungent chlorine-like odor. Sodium hypochlorite has poor stability at room temperature and is easily decomposed, especially under light and heating conditions, where it releases chlorine. The wastewater generated during the sodium hypochlorite production process contains harmful substances and requires special treatment before discharge or reuse.

[0003] At present, in the process of using the existing wastewater treatment device for sodium hypochlorite production, the first process when filtering the wastewater is to transport the wastewater to the interior of the primary filter chamber for filtering particulate impurities. The filtering of particulate impurities is mainly achieved by relying on the filter screen inside the wastewater treatment device. After using the filter screen for a period of time, the filter screen is prone to clogging. The clogged filter screen needs to be cleaned by using high-pressure water flushing or disassembling the filter screen. The filter components are mostly assembled by means of bolts, etc., which easily leads to the occurrence of problems such as the later disassembly and cleaning of the filter components. In order to solve this technical problem, the utility model proposes a wastewater treatment device for sodium hypochlorite production. Utility Model Content

When the rotating shaft is rotated, the rotation of the gear can move the two sets of racks to retract into the inside of the mounting shell. At this time, the rack is pulled out from the inside of the positioning frame, and the spring is in an elastically compressed state, which is convenient for later disassembly and assembly of the mounting frame. By rotating the positioning rod to make the arc plate and the through hole have the same angle, it is convenient to disassemble the filter from the inside of the mounting frame. The structure is simple and practical, and the filter can be disassembled and assembled without using external tools.

[0014] In the utility model, by providing components such as connecting blocks and limit blocks, the limiting blocks provided inside the tank body can be used to limit the upward and downward movement of the installation frame. After the connecting blocks made of rubber material on both sides of the installation frame are squeezed and deformed and inserted into the connecting grooves, the joints where the installation frame is inserted into the through grooves can be sealed to prevent wastewater from leaking inside the tank body.
