During the pre-treatment, the industrial wastewater needs to be filtered first. After filtering, some larger metal impurities are removed. If the filter is used for a long time, it is easy to cause the mesh to be clogged, which can directly affect the subsequent wastewater treatment effect. Utility Model Content

If the filter is used for a long time, it is easy to cause the mesh to be blocked, which is easy to directly affect the subsequent wastewater treatment effect.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an industrial wastewater ultrafiltration reverse osmosis graded water treatment device, comprising an industrial wastewater pool, a pretreatment box, a reverse osmosis treatment tank, and an ultrafiltration membrane tank, wherein limit plates are installed at both ends of the inner wall of the pretreatment box, a filter frame is arranged between the limit plates, a connecting block is fixed on one side of the filter frame, a through slot is opened inside one side of the pretreatment box, a sealing plate is fixed on one side of the connecting block, a handle is fixed on one side of the sealing plate, a sealing block is fixed on the other side of the sealing plate, and a bend pipe is installed on one side of the bottom end of the pretreatment box.

[0006] Preferably, two groups of the limit plates are installed at the front and rear ends of the inner wall of the pre-treatment box, and two groups of the through slots are distributed inside one side of the pre-treatment box.

[0007] Preferably, the aperture sizes of the two filter frames are different, and the outer dimension of the connecting block is smaller than the inner dimension of the through-slot.

[0008] Preferably, a first pump body is provided on one side of the industrial wastewater pool, one end of the first pump body is connected to a fifth drainage pipe, and the tail end of the fifth drainage pipe is interconnected with the top end of the pretreatment tank.

[0013] Compared with the prior art, the utility model has the following beneficial effects: the industrial wastewater ultrafiltration reverse osmosis classification water treatment device not only improves the filter processing capacity, but also improves the anti-clogging ability and water treatment effect of the device;

[0014] (1) By installing the limit plates at the front and rear ends of the inner wall of the pretreatment box, one filter frame is equipped with four limit plates for limiting, specifically two upper and lower limit plates at the front end and two upper and lower limit plates at the rear end, and the spacing of the same set of upper and lower limit plates is adapted to the filter frame, thereby achieving the purpose of limiting installation, and using the filter frame to perform preliminary filtration of industrial wastewater. After a period of use, the sealing plate is pulled outward, and the filter frame is taken out of the position of the through slot and leaves the interior of the pretreatment box.

When the raw liquid flows and is filtered from the circular filter plate, the driving motor inside the center plate is started to drive the transmission column to rotate. At this time, the crushing piece rotates to crush the materials that may be mixed. At the same time, the brush plate can clean the filter screen of the circular filter plate, thereby reducing the blockage phenomenon of the bend pipe during the operation and improving the anti-blockage ability;

[0016] (3) After the second pump body is started, the pretreated water source in the pretreatment box is extracted through the bend pipe, and then flows through the fourth drainage pipe to the second pressure pump for pressurization, and then reaches the inside of the reverse osmosis treatment tank through the third drainage pipe for reverse osmosis treatment. After the third pump body is started, the water source in the reverse osmosis treatment tank is drained through the second drainage pipe to the first pressure pump for pressurization, and then output through the main flow pipe and diverted to the inside of the ultrafiltration membrane tank through the diversion pipe to complete the ultrafiltration treatment, thereby improving the overall water treatment continuity during the working process.
