Description

Technical Field

[0001] The utility model relates to the technical field of chemical wastewater treatment. Specifically, it relates to a chemical wastewater treatment device. Background Technique

[0002] After pure water is used, its original physical or chemical properties change, becoming wastewater containing different kinds of impurities. Chemical wastewater is the process wastewater, cooling water, waste gas washing water, equipment and site flushing water, etc. discharged in chemical production. If these wastewaters are discharged without treatment, they will cause different degrees of pollution to water bodies, thus endangering human health and affecting the production of industry and agriculture.

[0003] The prior art discloses an application number: CN202322748785.8, with the name of a chemical wastewater treatment device. This application proposes to solve the problem that the filter holes on the surface of the filter screen are blocked by particulate impurities. The existing method is to disassemble the filter screen from the inside of the treatment device, then clean the disassembled filter screen, and after cleaning, reinstall the filter screen inside the treatment device. Although the above method can clean the filter screen, the whole operation process is very cumbersome and time-consuming, affecting the working efficiency of chemical wastewater treatment. By winding the filter screen around the unwinding reel, the extending end of the filter screen passes through two communication grooves and is fixedly connected to the side wall of the winding reel. At this time, the unfolded area of the filter screen will be laid inside the treatment tank and filter the chemical wastewater in the treatment tank. When too much impurities accumulate on the filter screen and affect the filtering effect of the filter screen, start the driving motor to drive the winding reel to rotate. The winding reel will wind up the filter screen inside the treatment tank and pull the unwinding reel to rotate. The unwinding reel will lay a new filter screen inside the treatment tank again, thus completing the replacement of the filter screen. The replacement method of the filter screen in this device is simple and convenient, and the replacement speed is very fast, avoiding the influence of replacing the filter screen on the development of wastewater treatment work and effectively improving the working efficiency.

[0004] However, although the above application solves the problem of frequent cleaning of the filter screen, after long-term use, especially after the whole filter screen is wound up, it still needs to be disassembled and cleaned, which is still rather troublesome and can be further improved. At the same time, when the filter screen filters statically, there is still an easy problem of slow filtering speed, which can also be further improved. Content of the Utility Model

[0029] Now, the present utility model will be further described in conjunction with the accompanying drawings and specific implementation manners. As Figures 1-4 shown, a chemical wastewater treatment device according to an embodiment of the present utility model includes a treatment tank 1 and driving rollers 3. The driving rollers 3 are arranged inside the treatment tank 1. There are four groups of driving rollers 3, and a filter net 4 is sleeved outside the driving rollers 3. The filter net 4 is of an annular structure, and the driving rollers 3 are rotationally connected to the treatment tank 1 through roller shafts 5. The roller shafts 5 penetrate through the treatment tank 1 and are rotationally connected to the treatment tank 1 through bearings. The top surface of the treatment tank 1 is integrally connected with a water inlet hopper 2, and the bottom surface of the treatment tank 1 is integrally connected with a drain hopper 13. One end inside the treatment tank 1 is fixedly connected with a sewage discharge tank 12, and the other end of the sewage discharge tank 12 penetrates through the treatment tank 1.

And the air outlet direction of the blowing head 10 points to the upper part of the sewage discharge tank 12. A second driving motor 15 is fixedly installed on the front facade of the treatment tank 1, and the output end of the second driving motor 15 is fixedly connected with one end of the roller shaft 5 of one of the driving rollers 3. The filter net 4 is annular. Chemical sewage enters the treatment tank 1 through the water inlet hopper 2. After being filtered by the filter net 4, impurities stay on the top surface of the filter net 4. The filtered sewage passes through the drain hopper 13 and is discharged. The second driving motor 15 drives the driving rollers 3 to rotate, thereby driving the filter net 4 to rotate, driving the impurities on the surface of the filter net 4 to flip to the upper part of the sewage discharge tank 12. Subsequently, the high-pressure air pump 17 generates high-pressure gas, and the high-pressure gas is transported to the shunt pipe 9 through the gas transmission pipe 16 and sprayed out through the blowing head 10 to perform high-pressure back blowing on the filter net 4, blowing the impurities on the surface of the filter net 4 into the sewage discharge tank 12 and discharging them through the screw conveyor 11. This device can continuously filter sewage, continuously clean the filter net 4, and automatically discharge impurities, saving the trouble of staff cleaning the filter net 4 and improving the convenience and working efficiency of use.

After being filtered by the filter screen 4, the impurities stay on the top surface of the filter screen 4. The filtered sewage passes through the drain hopper 13 and is discharged. The second driving motor 15 drives the driving roller 3 to rotate, thereby driving the filter screen 4 to rotate, driving the impurities on the surface of the filter screen 4 to flip above the sewage discharge groove 12. Subsequently, the high-pressure air pump 17 generates high-pressure gas, which is transported to the shunt pipe 9 through the air delivery pipe 16 and sprayed out through the blow head 10 to perform high-pressure back blowing on the filter screen 4, blowing the impurities on the surface of the filter screen 4 into the sewage discharge groove 12 and discharging them through the auger 11. This device can continuously filter sewage, continuously clean the filter screen 4, and automatically discharge the impurities, eliminating the trouble of the staff cleaning the filter screen 4, improving the convenience of use and work efficiency. At the same time, during the process of the filter screen 4 filtering sewage, the first driving motor 14 drives the rotating shaft 6 to rotate, thereby driving the striking ball 8 to rotate. The rotation of the striking ball 8 vibrates the filter screen 4, accelerating the sewage filtration through vibration, improving the sewage filtration speed and work efficiency.
