Description

Technical Field

[0001] The utility model relates to the technical field of industrial wastewater treatment, in particular to a multi-stage industrial wastewater treatment device. Background Art

[0002] In the process of industrial wastewater discharge, in order to make the industrial wastewater meet the discharge standards, it is usually necessary to treat the pollutants in the industrial wastewater. In order to facilitate the treatment of industrial wastewater, the staff usually use an industrial wastewater multi-stage treatment device. The existing industrial wastewater multi-stage treatment device is usually composed of a treatment box, a filter screen and a stirring mechanism.

[0003] For example: The utility model with application number CN202320826357.X discloses a multi-stage treatment device. Specifically, the utility model belongs to the field of industrial wastewater treatment, and in particular, a multi-stage treatment device. The existing treatment device does not have a corresponding buffer mechanism when feeding, and the impact force of the wastewater will cause certain damage to the filter screen. It is just a simple filtration, and the treatment method is single. There is also a pungent smell in the wastewater that cannot be purified, and the treatment is not thorough enough. The following scheme is proposed, which includes a base, and the top of the base is fixedly connected to a treatment box, and the top of the treatment box is fixedly connected to a liquid inlet pipe. Fixed plates are fixedly connected to the inner walls of both sides of the treatment box, and the tops of the two fixed plates are fixedly connected to the filter screen by bolts. One side of the treatment box is fixedly connected to a connecting pipe. The utility model reduces the impact force of the wastewater through a buffer mechanism, thereby reducing the impact of the wastewater on the filter screen. The harmful gases in the wastewater can be purified through the purification mechanism, so that the wastewater treatment is more thorough.

[0004] However, as far as the current traditional industrial wastewater multi-stage treatment device is concerned, during long-term use, in order to ensure the filtering effect of the filter on the wastewater, it is usually necessary to remove the filter regularly for cleaning. However, after the filter is removed, an opening will be left. At this time, the staff is required to temporarily seal the opening area with appropriate sealing materials such as rubber gaskets, sealing tapes, etc. to prevent wastewater leakage. The operation is relatively cumbersome and increases the labor intensity of the staff. Utility Model Content

[0005] In view of this, the utility model provides a multi-stage treatment device for industrial wastewater, which has a sealing plugging plate that can automatically seal the treatment box after the filter screen plate is removed, and when the filter screen plate is pulled out, the control rack will drive the control gear to rotate, and in the process of rotation of the control gear, the first bevel gear will be driven to rotate, and in the process of rotation of the first bevel gear, the two second bevel gears will be driven to rotate, and in the process of rotation of the two second bevel gears, the fixed shaft will be driven to rotate, and in the process of rotation of the fixed shaft, the third bevel gear will be driven to rotate, and in the process of rotation of the third bevel gear, the transmission shaft will be driven to rotate through the fourth bevel gear, so that the transmission worm drives the transmission worm wheel meshing with it to rotate, and in the process of rotation of the transmission worm wheel, the connecting shaft will be driven to rotate, and in the process of rotation of the connecting shaft, the sealing plugging plate will be flipped, so that the two sealing plugging plates are closed to seal the treatment box to prevent leakage of industrial wastewater.
