Description

Technical Field

[0001] This utility model relates to the field of cleaning and filtration equipment technology, and in particular to a device for pulse cleaning membrane filter components. Background Technology

[0002] Filtration is an operation in which liquid (or gas) in a suspension (or gas containing solid particles and heat) is passed through a medium under the action of a driving force or other external force, while solid particles and other substances are trapped by the filter medium, thereby separating solids and other substances from liquid (or gas).

[0003] Currently, when using a cleaning membrane to filter wastewater, impurities inside the wastewater easily adhere to one side of the cleaning membrane, causing a decrease in the membrane's permeability and thus slowing down the filtration effect. When a scraper is used to remove impurities from one side of the cleaning membrane, it not only easily damages the membrane but also causes some impurities to penetrate deeper into the filter pores, making them even more difficult to remove and causing irreversible damage to the membrane. Utility Model Content

[0004] In order to solve the problems of the prior art, this utility model provides a device for pulse cleaning membrane filter components.

[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0006] An apparatus for pulse-type cleaning of a membrane filtration assembly includes a cleaning tank. A bent baffle is fixed between the inner walls of the two sides of the cleaning tank near one edge. An adjustment cavity is formed inside the bent baffle. The top of the adjustment cavity extends to the top of the bent baffle, and the bottom of the adjustment cavity extends to one bottom side of the bent baffle. A hollow filter plate is fixed between the inner walls of the two sides of the cleaning tank. One side of the bent baffle is fixed to one side of the hollow filter plate. A pulse generator is disposed at the top of the cleaning tank near the hollow filter plate.

[0007] Optionally, the bottom of the pulse generator is provided with multiple air supply pipes at equal intervals, and each of the multiple air supply pipes is provided with multiple unidirectional nozzles at equal intervals on one side.

[0008] Optionally, one end of each of the plurality of unidirectional nozzles faces the hollow filter plate, and a cleaning membrane is provided inside the hollow filter plate.

[0009] Optionally, a water outlet pipe is provided on one side of the cleaning tank, and a drain outlet is provided at the bottom of the cleaning tank near one side edge. Multiple through-holes penetrating into the interior of the cleaning tank are provided at equal intervals on the inner top surface of the drain outlet, and the through-holes are connected to the regulating cavity.

[0010] Optionally, the adjustment cavity has multiple sealing plates slidably arranged at equal intervals at the through opening, and multiple openings are equally spaced on one side of the bending baffle. Each of the multiple openings has a cutting plate inside the adjustment cavity, and the bottom of each of the multiple cutting plates extends to one side of the sealing plate and is connected to the sealing plate.

[0011] Optionally, the top of the bending baffle is provided with a plurality of adjustment ports that extend into the adjustment cavity at equal intervals, the tops of the plurality of cut plates extend into the adjustment ports, and the tops of the plurality of cut plates are fixed with fixing blocks.

[0012] Optionally, a buffer pool is fixed between the inner walls of the cleaning pool near the other edge, the bottom of the buffer pool is open, and a vertical plate is fixed to the bottom of the buffer pool.

[0013] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time:

[0014] 1. In actual use, the fixed block is first moved to slide the cut plate to the side of the opening so that the opening is opened. At this time, the water inside the cleaning tank can flow through the opening to the hollow filter plate. The water is filtered by the cleaning membrane inside the hollow filter plate, and the filtered water is discharged through the outlet pipe.

[0015] 2. In this utility model, when cleaning the cleaning membrane, firstly, the sliding cut-off plate is used to close the opening, and at the same time, the closing plate is slid to one side of the through-hole to open the through-hole. Then, a pulse generator is used to supply pulsed high-pressure air to the air supply pipeline. The pulsed high-pressure air is sprayed onto the hollow filter plate through a one-way nozzle. Under the impact of the high-pressure pulsed air, the impurities deposited on the filter surface of the hollow filter plate and the cleaning membrane can be dislodged. The dislodged impurities can be discharged through the through-hole into the drain port. Attached Figure Description
