Description

Background Art

Industrial wastewater includes production wastewater, production sewage and cooling water, which refers to the wastewater and waste liquid generated in the industrial production process, which contains industrial production materials, intermediate products, by-products lost with the water, and pollutants generated in the production process.

The existing industrial wastewater has complex components, so it needs to undergo preliminary filtration to achieve liquid-solid separation during treatment. The existing filtration devices are roughly divided into mesh filters and centrifugal filters. The mesh filters have good filtration effects, and the centrifugal filters use centrifugal force to achieve liquid-solid separation with high filtration efficiency. However, there is a problem with these two filters. As the filters are used, the filtrate will accumulate in the equipment, which will lead to a decrease in filtration effect and filtration efficiency. Therefore, the existing filtration equipment needs to be shut down regularly to clean the filtrate. As a filtration device used for chemical wastewater, regular shutdown not only affects the filtration efficiency, but also causes the wastewater treatment process after filtration to stagnate. For this reason, a chemical wastewater treatment device is proposed.

In this embodiment, the anti-clogging unit 4 includes a water pump 41 and a water pipe 42. The water pump 41 is installed on the barrel cover 12. The water pipe 42 passes through the top center of the barrel cover 12 and extends into the treatment barrel 1. The water pipe 42 is located in a section inside the treatment barrel 1 and is connected to a water guide plate 43. The water guide plate 43 is hollow inside and is connected to the water pipe 42. The other side of the water guide plate 43 is in contact with the filter 11. The upper end of the water pipe 42 is connected to the water outlet end of the water pump 41. The water inlet end of the water pump 41 is connected to a water receiving pipe 44, and the water receiving pipe 44 is connected to the water outlet pipe 13.

The working process and principle of the present invention are as follows:

When in use, industrial waste water is connected to the water inlet pipe 14, and the industrial waste water will enter the treatment barrel 1 through the water inlet pipe 14. When the waste water in the treatment barrel 1 is about to be filled, the motor 24 is turned on, and the treatment barrel 1 is driven to rotate through the meshing of the gear 241 and the ring gear 242. The industrial waste water in the treatment barrel 1 will be separated from the liquid by the centrifugal force, and the waste in the waste water will be precipitated against the barrel wall, and the waste liquid will pass through the filter 11 and be discharged from the outlet pipe 13 to enter the next treatment process. Since most of the waste is precipitated downward along the barrel wall, it will not be intercepted by the filter and the mesh will be blocked, and it has a higher filtration and separation efficiency. When some waste with lower density in the waste water enters the treatment barrel 1, it is close to the center and is less affected by the centrifugal force. It is easily affected by the water flow at the mesh of the filter 11 and sticks to the mesh surface. Part of the mesh holes are blocked, and the water pump 41 is turned on when the treatment barrel 1 is rotating. The water pump 41 will pressurize part of the waste liquid in the outlet pipe 13 through the water connecting pipe 44 and send it into the water guide pipe 42 and the water guide plate 43. The pressurized waste liquid will impact the filter screen 11 in the opposite direction. Since the filter screen 11 is in a rotating state, the waste material attached to the filter screen 11 will be washed away by the reverse impact of the waste liquid, so that it will leave the mesh surface and flow toward the barrel wall. As the waste material moves toward the barrel wall, the centrifugal force of the waste material will increase, while the influence of the water flow will decrease. These waste materials with lower density will gradually settle along the barrel wall. Since the water guide plate 43 is in a stationary state, the rotating water flow will flow to both sides of the water guide plate 43 when it encounters the water guide plate 43, and the water flow flowing toward the filter screen 11 will further backwash the filter screen 11.

During the rotation of the processing barrel 1, the guide rod 351 will slide along the path in the guide groove 352, and the moving block 33 located in the sewage box 31 will slide back and forth under the pull of the connecting rod 35 and the guide rod 351. When the moving block 33 does not slide, the waste material deposited at the bottom of the processing barrel 1 will fall into the sewage box 31 with the scraper 38 and fill the space between the moving block 33 and the curved plate 34. When the moving block 33 slides outward, the waste material in the sewage box 31 will move with the moving block 33 and the curved plate 34. After blocking the material outlet 32, the arc plate 34 will be blocked by the blocking rod 371 and will no longer slide. At this time, the top pipe opening of the drainage pipe 362 is in the material outlet 32, and the moving block 33 continues to slide to squeeze the waste in the sewage box 31. After being pressed, the waste liquid contained in the waste will pass through the permeable net 361 into the drainage groove 36 and return to the processing barrel 1 through the drainage pipe 362. As the moving block 33 is squeezed, the sliding rod 332 will push the sliding block 333 to slide in the sliding cavity 331. When the pressure sensor 336 is pressurized, the conductive elastic The circuit where the spring 373 is located will be energized, and the conductive spring 373 will shrink after being energized, pulling the circular plate 372 and the blocking rod 371 to slide upward, releasing the obstruction to the curved plate 34, and the curved plate 34 will continue to slide together with the moving block 33. When the curved plate 34 leaves the sewage discharge box 31, under the action of the reset spring 335, the curved plate 34 will pop outward. The advantage of this is that the curved plate 34 will no longer clamp the extruded waste together with the moving block 33. When the moving block 33 moves to the edge of the sewage discharge box 31, the waste will not The clamped material will fall off by itself, completing the discharge of the waste material. During the wastewater filtration and separation work, the filtered waste material can be cleaned without stopping the machine, thereby improving the wastewater filtration treatment efficiency. When the moving block 33 moves back, the moving block 33 and the arc plate 34 will carry air back to the drop port 32, and the air will enter the treatment barrel 1 from the bottom of the barrel and turn into large bubbles. The large bubbles float up and are divided into a large number of small bubbles through the filter screen 11 and mixed with the waste liquid, thereby increasing the oxygen content of the waste material and helping microorganisms to decompose organic matter in the waste liquid.

It is known from common technical knowledge that the present invention can be implemented by other embodiments that do not deviate from its spirit or essential features. Therefore, the above disclosed embodiments are only illustrative in all respects and are not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are included in the present invention.
