Assembly line type immersion work harmful water treatment device for chemical production

Abstract

The invention belongs to the technical field of wastewater treatment, and discloses an assembly line type immersion work harmful water treatment device for chemical production. The assembly line type immersion work harmful water treatment device comprises a wastewater treatment tank, a motor, a ball screw, a slide block and a push rod. The motor is arranged above the wastewater treatment tank, and an output shaft of the motor is in transmission connection with the ball screw; the two sliding blocks are movably connected to the top and the bottom of the ball screw in a sleeving mode correspondingly. The water pressure in the cavity is increased, so that water in the cavity between the partition plate and the drainage tank can penetrate through the ultrafiltration device to re-enter the inner cavity of the ultrafiltration device, and accumulated particles between micropores of the ultrafiltration device and membrane filaments are backwashed out due to reverse flow in the micropores of the ultrafiltration device, so that the purpose of cleaning the ultrafiltration device is achieved. The ultrafiltration device does not need to be disassembled and the like, so that the treatment is convenient, and the influence of cleaning time on subsequent wastewater treatment is not reduced.

Description

Technical field [0001] The present invention belongs to the technical field of wastewater treatment, and is specifically a harmful water treatment device for chemical production pipeline immersion. Background technique [0002] The immersion ultrafiltration device is very widely used in the field of wastewater treatment. Its microporous material in which itself can intercept the impurity particles in wastewater, which is physically effective to filter out impurities in wastewater. [0003] In the existing ultrafiltration device, the wastewater is generally compressed by the water pressure through the ultrafiltration device, and the micropores of the ultrafiltration device can block the particulate impurities, so that it cannot be passed, while the particles are also blocked by the ultrafiltration device. Among the micropores and filters of the ultrafiltration device, after a long-term filtering, the micropores of the ultrafiltration device will cause the filtration performance de...

AI Technical Summary

Problems solved by technology

[0003] In the existing ultrafiltration device, the waste water is generally forced to pass through the ultrafiltration device through water pressure. The micropores of the ultrafiltration device can intercept particulate impurities, making it impossible for them to pass through, and the particles will also be blocked by the ultrafiltration device. It exists in the micropores and membrane filaments of the ultrafiltration device. After a long time of filtration, the micropores of the ultrafiltration device will have a decrease in filtration performance due to the accumulation of a large number of particles, and the filtration speed is slow, which affects the ultrafiltration. The service life of the device. Therefore, the general treatment method is to disassemble the ultrafiltration device and clean it, rinse it with water, and flush out the particles and impurities in the micropores and membrane filaments. After the treatment, it may be put into use again. It is also possible to directly replace the ultrafiltration device, but the cost is relatively increased, and dismantling and replacing the ultrafiltration device also affects the subsequent wastewater treatment process, delays time, and the operation process is more cumbersome
