Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a device for purifying and reusing heat treatment wastewater. Background Technology

[0002] Tempering is a technique in steelmaking that involves reheating steel that has undergone quenching hardening or normalization to a suitable temperature below the lower critical temperature, holding it at that temperature for a period of time, and then cooling it in air, water, oil, or other media to increase the toughness of the material.

[0003] A large amount of wastewater will be generated during the tempering process. Direct discharge of this wastewater would be wasteful. Furthermore, oxide scale may be generated on the surface of the steel during the heating process. After cooling in water, the oxide scale will mix with the water. The oxide scale can be recycled and reused. In view of this technical problem, this application proposes a heat treatment wastewater purification and reuse device. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a wastewater purification and reuse device for heat treatment. Through a collector connected to a pumping pipe and a flexible hose, wastewater can be fed into a purification tank. Impurities such as oxide scale in the wastewater are trapped by a filter screen, and the filtered water passes through the filter screen and falls to the bottom of the purification tank. It is then discharged into a drain pipe via a connecting hose and into a water tank for reuse. This process recovers oxide scale and purifies the water, saving production costs.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A wastewater purification and reuse device for heat treatment includes a water tank. A fixed block is connected to the inner wall of the water tank via a collection component. A support groove is fixedly connected to the right end of the water tank.

A driving component is provided at the bottom end of the base plate. A discharge component is provided at the front end of the purification box. A support plate is fixedly connected to the right end of the water tank.

[0006] Furthermore, the collection assembly includes a collector fixedly connected to the right side of the inner wall of the water tank, a water pump pipe passing through the top of the collector, a second water pump being provided on the outer wall of the water pump pipe, and a connecting hose being fixedly connected to the other end of the water pump pipe.

[0007] Furthermore, a second fixing ring is fixedly connected to the outer wall of the water pump pipe, and the right end of the second fixing ring is fixedly connected to the inner wall of the right end of the water tank.

[0009] Furthermore, the top of the sealing ring is located at the bottom of the purification chamber, and the outer diameter of the top of the filter screen matches the inner wall of the limiting ring.

[0010] Furthermore, the drive assembly includes a rotating shaft fixedly connected to the bottom end of the base plate, a drive shaft being snapped into the inner wall of the bottom end of the rotating shaft, and a drive motor being fixedly connected to the bottom end of the support plate.

[0011] Furthermore, the outer wall of the rotating shaft is rotatably connected to the inner wall of the sealing cover, the outer wall of the drive shaft is rotatably connected to the inner wall of the support plate, and the bottom end of the drive shaft is fixedly connected to the drive end of the drive motor.
