This device can fully mix chemical wastewater, catalyst and oxidant, so as to improve the treatment effect of chemical wastewater. The wastewater after catalytic and oxidation treatment of this processor can be discharged through the overflow port and the outlet pipe. However, the wastewater contains built-in particulate matter, which makes the discharge pipe of this wastewater oxidation device easy to be blocked, affecting the treatment effect and discharge efficiency of catalytic oxidation. It is necessary to set a discharge pipe that is not easy to be blocked or a discharge pipe cleaning mechanism to clean the particulate matter and improve work efficiency.

[0004] In view of the above problems, a catalytic oxidation device for wastewater treatment is proposed. Utility Model Content

[0005] The utility model aims to provide a catalytic oxidation device for wastewater treatment, which solves the problem that the wastewater treated by the existing catalytic oxidation device for wastewater treatment in the background technology can be discharged through the overflow port and the outlet pipe, but the wastewater contains particles, which makes the discharge pipe of the wastewater oxidation device easy to be blocked, affecting the treatment effect and discharge efficiency of the catalytic oxidation, and it is necessary to set a discharge pipe that is not easy to be blocked or a discharge pipe cleaning mechanism to clean the particles and improve the working efficiency.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a catalytic oxidation device for wastewater treatment, comprising a mixing box mechanism, the lower end of the mixing box mechanism is connected to a discharging mechanism, the interior of the discharging mechanism is penetrated by an anti-clogging mechanism for waste residue cleaning, the mixing box mechanism comprises a mixing box body, the lower end of the mixing box body is provided with a centralized discharge port, the discharging mechanism comprises a triangular material frame threadedly connected to the centralized discharge port, a discharging pipe is fixedly provided at the lower end of the triangular material frame, an inclined plate is provided at one end of the discharging pipe, a closing block is fixed inside the front end of the discharging pipe, the anti-clogging mechanism comprises a driving cylinder inserted into the discharging pipe, the output end of the driving cylinder is connected to a closing plate, and a rotating plate is rotatably provided at the lower end of the closing plate.

[0014] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0015] 1. The utility model provides a catalytic oxidation device for wastewater treatment. Through the arrangement of a triangular material frame and a closing block in a discharge mechanism, a driving cylinder can push a closing plate to move forward until it engages with the closing block. At the same time, the closing block limits the rotating plate, so that the closing block, the closing plate and the rotating plate can cooperate to achieve the closure of the discharge pipe to prevent overflow when wastewater is mixed. When the driving cylinder drives the closing plate to be recovered to one side of the inclined plate, the inclined plate lifts the rotating plate so that the anti-blocking mechanism can be pushed open, thereby solving the problem of opening and closing the discharge pipe of the existing catalytic oxidation device for wastewater treatment.

[0016] 2. The utility model provides a catalytic oxidation device for wastewater treatment. Through the setting of the anti-clogging mechanism, since the particles will sink, the particles dragged back when the rotating plate is retracted can move to the front end of the rotating plate, and be driven by the driving cylinder to move to the side of the closing block for discharge. The combination of the closing plate and the rotating plate can achieve complete closure of the discharge pipe. At the same time, when the closing plate moves to the side of the inclined plate, the rotating plate can be opened without affecting the normal discharge of water. At the same time, the closing plate and the rotating plate can scrape the inner wall of the discharge pipe when moving forward to discharge the particles, thereby preventing the discharge pipe from being blocked and affecting the treatment effect and discharge efficiency of the catalytic oxidation. This solves the problem that the wastewater treated by the existing catalytic oxidation device for wastewater treatment can be discharged through the overflow port and the outlet pipe, but the wastewater has built-in particles, which makes the discharge pipe of the wastewater oxidation device easy to be blocked, affecting the treatment effect and discharge efficiency of the catalytic oxidation. It is necessary to provide a discharge pipe that is not easy to be blocked or a discharge pipe cleaning mechanism to clean the particles and improve work efficiency.
