Problems solved by technology

However, after the filter membrane has been used for a period of time, the filter holes on the filter membrane will inevitably be blocked to a certain extent, which will seriously affect the water filtration efficiency of the equipment. Therefore, it is necessary to clean the filter membrane in time
And the existing filter membrane cleaning methods generally include the following two types: the first one is to manually remove the filter membrane for cleaning, but this method takes a long time, has low efficiency, and the labor intensity of the workers is high, and when the workers clean the filter membrane, It is easy to cause the filter membrane to be damaged and scrapped; the second method is to clean the filter membrane by backflushing with clean water, but this method seriously wastes clean water, and the clean water will be turned back into sewage in the process, and the water filtration efficiency is low, which affects economic benefits

Embodiment 1

[0026] see figure 1 As shown, a membrane-transferred sewage treatment device of the present invention includes a sewage filtration system, a membrane cleaning system, and a membrane conveying system.

[0027] The sewage filtration system includes a plurality of water-absorbing plates 11 disposed in the sewage and arranged at intervals, filter membranes 12 covering both surfaces of the water-absorbing plates 11, and a first suction device connected to the water-absorbing plates 11; wherein , the filter membrane 12 preferably adopts a high-strength nano-scale water filtration membrane. According to the characteristics of the filter membrane 12, the contact surface of the filter membrane 12 and the water-absorbing plate 11 is a fiber surface, and the surface in contact with the sewage is a smooth surface; the water-absorbing plate Both sides of 11 are provided with arrays of water tanks, and filter membrane 12 is covered on the array of water tanks to form a negative pressure cav...

Embodiment 2

[0038] see figure 2 As shown, compared with Embodiment 1, the main difference is that: the membrane washing plate 22 can be provided with one piece, which is arranged outside the end area where the filter membrane 12 completes one cycle, and is smooth with the filter membrane 12 that is separated from the sewage. In addition, the filter membrane cleaning system can also be provided with an ultrasonic water washing device, which is installed on the transport path before the filter membrane 12 from sewage enters the membrane washing plate 22, and is used for loosening the filter membrane 12 microns. The obstinate impurities in the pores are conducive to the dredging of the micropores of the filter membrane 12 by the subsequent membrane washing plate 22 .

Embodiment 3

[0040] see image 3 As shown, compared with Embodiment 1, the main difference is that: the driving shaft 32 and the driven shaft 33 are distributed in two rows up and down, and the sewage filtration system is provided with a plurality of belt-shaped filter membranes 12 connected end to end. , the filter membranes 12 are respectively circularly transported around a set of corresponding driving shafts 32 and driven shafts 33 facing up and down. Correspondingly, the membrane washing plate 22 is provided with a plurality of pieces, which are respectively arranged between two adjacent filter membranes 12 which are circulated and transported, and are dislocated with the water absorbing plate 11 in two rows up and down, left and right.

Abstract

The invention provides a membrane transferring sewage treatment machine which comprises a sewage filtering system, a filtering membrane cleaning system and a filtering membrane conveying system, wherein the sewage filtering system comprises a plurality of water suction plates, a filtering membrane and a first suction device; sewage is sucked by negative pressure of the first suction device and is filtered by the filtering membrane to obtain pure water; the pure water flows into the water suction plates; the filtering membrane cleaning system comprises scraping strips, a membrane washing plate and a second suction device; impurities in microholes in the filtering membrane are sucked into the membrane washing plate by negative pressure of the second suction device; the filtering membrane conveying system comprises a motor, a transmission mechanism, driving shafts for connecting and conveying the filtering membrane and driven shafts; the driving shafts are driven by the transmission mechanism to rotate; the water suction plates are arranged in an interlayer surrounded by the filtering membrane around each driven shaft. The membrane transferring sewage treatment machine can be used for realizing functions of filtering sewage and cleaning the filtering membrane; in a production process, the machine does not need to be stopped frequently to clean and replace the filtering membrane, so that the membrane transferring sewage treatment machine can be used for continuous production operation, and the water filtering efficiency is high.

Description

technical field [0001] The invention relates to the field of sewage purification, in particular to a membrane-transferred sewage treatment machine. Background technique [0002] At present, the devices for treating sewage with filter membranes generally cover the filter membranes on both sides of splints with cavities, and use negative pressure to attract sewage to be filtered through the filter membranes. The impurities in the sewage are isolated on the outside of the filter membranes. The filtered clean water is output through the suction port on the splint. However, after the filter membrane has been used for a period of time, the filter holes on the filter membrane will inevitably be blocked to a certain extent, which will seriously affect the water filtration efficiency of the equipment. Therefore, the filter membrane needs to be cleaned in time. And the existing filter membrane cleaning methods generally include the following two types: the first one is to manually re...
