Description

Technical Field

[0001] The utility model relates to the technical field of sewage filtering equipment, in particular to a tubular ultrafiltration membrane dredging and cleaning device. Background Art

[0002] Ultrafiltration membranes are widely used in the water treatment industry. They use the principle of membrane separation to drive the membrane under external pressure to pass water molecules and solutes with smaller molecular weights, and intercept colloids, particles, and substances with relatively larger molecular weights in the water to achieve the purpose of purifying water. During the use of tubular ultrafiltration membranes, particles, colloids, metal ions and other substances in the water will be deposited on the surface of the ultrafiltration membrane, causing the membrane pores to be blocked, reducing the membrane flux, affecting the water treatment effect, and shortening the service life of the membrane. At this time, it is necessary to clean and dredge the blocked ultrafiltration membrane pores to restore the filtration performance of the membrane.

[0003] At present, the cleaning methods of tubular ultrafiltration membranes mainly include physical cleaning and chemical cleaning. Among them, the physical cleaning method mainly adopts hydraulic flushing, which uses raw water to directly flush impurities in the membrane pores and the water inlet end face. However, due to the limited water pressure (the maximum pressure that the membrane can withstand is limited) and the constant water flow direction during flushing, this hydraulic flushing method will cause the pollutants in the membrane pores to be compacted, completely blocking the membrane pores, and is relatively wasteful of water resources, high cost and poor effect. Summary of the invention

[0004] Therefore, it is necessary to provide a device capable of effectively cleaning the tubular ultrafiltration membrane to solve the problem that the tubular ultrafiltration membrane is not cleaned thoroughly and the cost is high.

[0005] To achieve the above-mentioned purpose, the inventor provides a tubular ultrafiltration membrane unclogging and cleaning device, including a power mechanism and an output mechanism, the output mechanism includes a steel pipe, the head end of the steel pipe is located inside the output mechanism housing, and the tail end of the steel pipe is located outside the output mechanism housing, the head end of the steel pipe is provided with an air inlet pipe and a water inlet pipe in parallel, the housing of the output mechanism is provided with a water inlet and an air inlet, the water inlet is connected to the water inlet pipe, and the air inlet is connected to the air inlet pipe; the output mechanism also includes a drill bit and a motor, the drill bit is fixed to the inside of the steel pipe by a drill chuck, the motor is connected to the drill chuck that fixes the drill bit by a gear, and controls the drill bit to rotate in the steel pipe; a sewage outlet is provided on the steel pipe outside the output mechanism housing.

[0006] Furthermore, the power mechanism includes a battery, a speed regulating device, a commutator, a carbon brush, a control button and a heat dissipation fan blade, and the commutator is connected to the motor.

[0007] Furthermore, a bearing for sealing the head end of the steel pipe is disposed on the head end face of the steel pipe, and a drill clamp for fixing the drill bit passes through the bearing and is connected to the motor.

[0008] Furthermore, a stop ring and a thrust ring are provided on the bearing.

[0009] Furthermore, a handle is provided on the housing of the output mechanism.

[0010] Furthermore, the outer cover of the steel pipe is provided with a protective cover.

[0011] Different from the prior art, the above technical solution has the following beneficial effects:

[0012] The utility model can generate rotating airflow or water flow by introducing compressed air and high-pressure water flow into the steel pipe and utilizing the rotation of the drill bit, thereby performing rotational cutting on blocking impurities on the membrane pores of the tubular ultrafiltration membrane, and under the strong flushing action of the water flow and the air flow, the impurities and sludge are washed away from the tubular ultrafiltration membrane, thereby effectively removing impurities and particulate matter on the membrane surface, achieving a significant cleaning effect and also reducing the cleaning cost.
