Description

Technical Field

[0001] This utility model belongs to the field of waste liquid treatment technology, and specifically relates to a waste liquid treatment device for the production of tin stripping agent. Background Technology

[0002] The production of tin stripping agents generates waste liquid, which contains a large number of harmful substances, such as heavy metal ions (copper, iron, tin, etc.), acids (nitric acid, hydrochloric acid, etc.) and organic additives. If these substances are discharged directly without treatment, they will cause serious pollution to the environment, affect the ecological balance and human health.

[0003] Before waste liquid treatment, it needs to be introduced into a sedimentation tank to allow the solids in the waste liquid to settle. Then the clear liquid is extracted for treatment. However, when the clear liquid is extracted by the pump, the liquid easily carries the settled solids and they enter the pump body. This not only easily damages the pump body, but also affects the treatment effect of the waste liquid. Utility Model Content

[0033] There are several floats 203.

[0034] The extraction assembly includes a pump body 3 located on one side of the treatment tank 1. The drain end of the pump body 3 is connected to one side of the treatment tank 1. The pumping end of the pump body 3 is fixedly connected to a liquid extraction pipe 4 via a flange. The bottom end of the liquid extraction pipe 4 is connected to a metal flexible hose 5. One end of the metal flexible hose 5 is located inside the sedimentation tank 2.

[0035] The metal hose 5 includes a limiting ring 501 and a hook 502. The limiting ring 501 is fixedly connected to the outside of the metal hose 5 by screws, and the hook 502 is fixedly connected to the bottom of the limiting ring 501.

[0036] Hook 502 is hung inside the mesh of filter screen 202.

[0037] Brief description of the usage process: Waste liquid enters the sedimentation tank 2 through the delivery pipe 201. As the liquid level rises, the float ball 203 drives the filter screen 202 to rise. The filter screen 202 can be moved stably through the connecting block 204 and the guide rod 205, thereby adjusting the distance between the filter screen 202 and the bottom of the tank, which facilitates the sedimentation of solids in the waste liquid. When the filter screen 202 moves, the metal hose 5 can be extended or retracted through the hook 502 and the limiting ring 501. After the liquid has been standing in the sedimentation tank 2 for a period of time, the pump body 3 is started to pump the liquid into the treatment tank 1 through the liquid extraction pipe 4. The filter screen 202 can prevent solids from entering the pump body 3 with the liquid, thereby improving the service life of the pump body 3 and facilitating subsequent liquid treatment.

[0038] Example 2:

[0039] refer to Figure 1 and Figure 3 The stirring assembly includes a motor 6 located at the top of the processing tank 1, with a connecting shaft 7 fixedly connected to the output end of the motor 6, and stirring blades 8 provided on the outer side of the bottom end of the connecting shaft 7.

[0041] One end of the spring 704 is fixedly connected to one side of the scraper 702, and the other end of the spring 704 is fixedly connected to one side of the fixing plate 703.

[0042] Brief description of the usage process: After the liquid enters the treatment tank 1, the treatment agent (such as alkali and catalyst) is added into the treatment tank 1 through the dosing port. Then, the motor 6 is started to drive the connecting shaft 7 to rotate the stirring blade 8, so that the agent is mixed with the waste liquid. When the connecting shaft 7 rotates, the connecting rod 701 can also drive the scraper 702 to rotate. The scraper 702 can prevent small impurities in the liquid from being adsorbed on the inner wall of the tank. The spring 704 can buffer the scraper 702 during the rotation process.
