Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a high-flux, anti-clogging, submerged ultrafiltration membrane integrated device. Background Technology

[0002] Submersible ultrafiltration membrane integrated devices immerse the ultrafiltration membrane module in the water to be treated. Utilizing the sieving effect of the membrane, water and small molecules permeate through the membrane under the pressure difference, while large molecules, colloids, bacteria, etc. are retained, thereby achieving water purification and separation. Submersible ultrafiltration membranes are widely used due to their high filtration performance and small footprint.

[0003] However, traditional submerged ultrafiltration membrane devices are easily fouled by suspended solids, colloids and organic matter in wastewater during long-term operation, resulting in the formation of a fouling layer on the membrane surface, increasing filtration resistance and reducing water treatment efficiency. Therefore, we propose a high-flux, anti-clogging submerged ultrafiltration membrane integrated device. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a high-flux, anti-clogging, submerged ultrafiltration membrane integrated device.

[0005] This utility model is achieved using the following technical solution: a high-flux, anti-clogging, submerged ultrafiltration membrane integrated device, comprising a wastewater tank, an installation frame fixedly connected to the bottom of the inner wall of the wastewater tank, a plurality of ultrafiltration membranes fixedly installed on the inner wall of the installation frame, a flushing assembly provided at the left end of the wastewater tank, a clear water tank provided at the right end of the wastewater tank, a stirring assembly provided inside the clear water tank, a water pump pipe connected to the top of the ultrafiltration membrane, a valve installed on the inner wall of the water pump pipe, a water pump fixedly connected to one end of the water pump pipe, a drain pipe connected to the end of the water pump away from the water pump pipe, and a fixing base fixedly connected to the bottom of the water pump.

[0006] The flushing assembly includes a flushing pump, a fixing plate is fixedly connected to the bottom of the flushing pump, an extraction pipe is connected to the left end of the flushing pump, a delivery pipe is connected to the right end of the flushing pump, a plurality of connecting pipes are connected to the inner wall of the delivery pipe, and a flushing water tank is provided at the lower end of the flushing pump.

[0007] The above technical solution involves starting a flushing pump, which draws flushing water from the flushing tank through an extraction pipe, delivers it to the connecting pipe through a delivery pipe, and then delivers the flushing water to several ultrafiltration membranes through the connecting pipe. This backwashing process prevents the ultrafiltration membranes from clogging, extends their lifespan, and improves wastewater treatment efficiency.

[0008] As a further improvement to the above solution, the right end of the fixing plate is fixedly connected to the left end of the sewage tank, the end of the connecting pipe away from the conveying pipe is connected to the ultrafiltration membrane, and the right end of the flushing water tank is fixedly connected to the left end of the sewage tank.

[0009] With the above technical solution, there are several connecting tubes and several ultrafiltration membranes. The connecting tubes facilitate the delivery of flushing water to the inside of the ultrafiltration membrane, and the water pressure flushes away the impurities attached to the inside of the micropores of the ultrafiltration membrane.

[0010] As a further improvement to the above solution, the end of the drain pipe away from the water pump extends into the interior of the clear water tank, and the right end of the fixing seat is fixedly connected to the left end of the sewage tank.

[0011] Through the above technical solution, the water pump draws water that has passed through the ultrafiltration membrane through the water pumping pipe and transports it to the inside of the clear water tank through the drain pipe, so that the filtered water can be transported to the clear water tank for storage.

[0012] As a further improvement to the above solution, the stirring assembly includes a motor, the output end of which is fixedly connected to a fixed shaft, and stirring blades are fixedly connected to the surface of the fixed shaft.

[0013] The above technical solution uses a motor to drive a fixed shaft to rotate, which in turn causes the stirring blades to rotate. The stirring blades agitate the filtered water, making the water flow and facilitating uniform sterilization of the water in the subsequent process.

[0014] As a further improvement to the above solution, the rear end of the motor is fixedly connected to the front end of the clear water tank.

[0015] As a further improvement to the above solution, the surface of the fixed shaft is rotatably connected to the inner wall of the clear water tank.

[0016] As a further improvement to the above solution, a fixing frame is fixedly connected to the top of the clear water tank, and an ultraviolet germicidal lamp is fixedly connected to the top of the inner wall of the fixing frame.

[0017] Through the above technical solutions, ultraviolet germicidal lamps can effectively kill bacteria and viruses in water, further improving water quality.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] This invention improves wastewater treatment efficiency by setting up a flushing assembly. Specifically, by activating a flushing pump, the flushing pump draws flushing water from the flushing tank through an extraction pipe, delivers it to the inside of a connecting pipe through a delivery pipe, and then delivers the flushing water to several ultrafiltration membranes through the connecting pipe. This backwashing of the ultrafiltration membranes prevents them from clogging, extends their lifespan, and thus improves wastewater treatment efficiency.

[0020] This invention incorporates a stirring assembly and an ultraviolet germicidal lamp. Specifically, by starting a motor, the motor drives a fixed shaft to rotate, causing the stirring blades to rotate. The rotation of the stirring blades agitates the water inside the clear water tank, ensuring that the ultraviolet germicidal lamp can evenly sterilize the water inside the tank, thus improving the sterilization effect and efficiency, and consequently improving the quality of the treated water.

[0031] The flushing assembly 4 includes a flushing pump 401, with a fixed plate 402 fixedly connected to the bottom of the flushing pump 401. The left end of the flushing pump 401 is connected to an extraction pipe 403, and the right end of the flushing pump 401 is connected to a delivery pipe 404. Several connecting pipes 405 are connected to the inner wall of the delivery pipe 404. A flushing water tank 406 is provided at the lower end of the flushing pump 401. When it is necessary to clean the ultrafiltration membrane 3, the valve 8 is closed and the flushing pump 401 is started. The flushing pump 401 extracts the flushing water from the flushing water tank 406 through the extraction pipe 403 and delivers it to the inside of the connecting pipes 405 through the delivery pipes 404. The flushing water is then delivered to the inside of several ultrafiltration membranes 3 through the connecting pipes 405 to backwash the several ultrafiltration membranes 3, prevent the ultrafiltration membranes 3 from clogging, extend the life of the ultrafiltration membranes 3, and thus improve the wastewater treatment efficiency.

[0032] The right end of the fixing plate 402 is fixedly connected to the left end of the sewage tank 1, the end of the connecting pipe 405 away from the conveying pipe 404 is connected to the ultrafiltration membrane 3, and the right end of the flushing water tank 406 is fixedly connected to the left end of the sewage tank 1.

[0034] The stirring assembly 6 includes a motor 601. The output end of the motor 601 is fixedly connected to a fixed shaft 602. A stirring blade 603 is fixedly connected to the surface of the fixed shaft 602. When the motor 601 is started, the motor 601 drives the fixed shaft 602 to rotate, causing the stirring blade 603 to rotate. The rotation of the stirring blade 603 stirs the water inside the clear water tank 5.

[0035] The rear end of motor 601 is fixedly connected to the front end of clear water tank 5.

The ultrafiltration membrane 3 can effectively intercept suspended particles, colloids, macromolecular organic matter, and microorganisms in the water. The water pump 9 is started, and the water pump 9 draws water that has passed through the inside of the ultrafiltration membrane 3 through the water pumping pipe 7 and transports it to the inside of the clear water tank 5 through the drain pipe 10. The filtered water is stored in the clear water tank 5. When it is necessary to sterilize the water inside the clear water tank 5, the ultraviolet sterilization lamp 13 is started, and then the motor 601 is started. The motor 601 drives the fixed shaft 602 to rotate, so that the stirring blade 603 rotates. The rotation of 03 agitates the water inside the clear water tank 5, ensuring that the ultraviolet germicidal lamp 13 can evenly sterilize the water inside the clear water tank 5, improving the sterilization effect and efficiency, and thus improving the quality of the treated water. When it is necessary to clean the ultrafiltration membrane 3, the valve 8 is closed and the flushing pump 401 is started. The flushing pump 401 draws the flushing water from the flushing water tank 406 through the extraction pipe 403 and delivers it to the inside of the connecting pipe 405 through the delivery pipe 404. The flushing water is then delivered to several ultrafiltration membranes 3 through the connecting pipe 405 to backwash the several ultrafiltration membranes 3, preventing the ultrafiltration membranes 3 from clogging, extending the life of the ultrafiltration membranes 3, and thus improving the wastewater treatment efficiency.
