Description

Technical Field

[0001] The utility model relates to the technical field of MBR flat membranes, in particular to an MBR flat membrane online cleaning brush. Background Art

[0002] MBR, also known as membrane bioreactor, is a new water treatment technology that combines activated sludge method with membrane separation technology. Due to the efficient separation effect of the membrane, the separation effect is much better than that of traditional sedimentation tanks. The treated water is extremely clear, the suspended solids and turbidity are close to zero, bacteria and viruses are largely removed, and the effluent quality is better than the domestic miscellaneous water quality standard issued by the Ministry of Construction, and can be directly reused as non-drinking municipal miscellaneous water.

[0003] In application number: CN201922426866.X, an MBR membrane assembly device capable of online cleaning is disclosed. By setting a fixed plate, a rotating rod, a roller, a cleaning roller and a cleaning brush, the fixed plate is driven to rise while the slider rises, and the fixed plate drives the roller to rise through the rotating rod. At the same time, because the roller and the support plate are against each other, it rotates when it rises, and when the roller rotates, it drives the cleaning roller to rotate synchronously, and then the cleaning roller drives the cleaning brush to clean the surface of the MBR membrane assembly, and the cleaning effect and efficiency are good. However, the above design still has shortcomings. The device cannot be limited inside the water treatment device, and the cleaning component cannot be flexibly installed.

[0004] To this end, we propose an MBR flat membrane online cleaning brush. Utility Model Content

[0009] By adopting the above technical solution and the design of the support frame and the mounting seat, it is convenient to install the assembly component on the support frame. The assembly component can be threadedly connected at both ends or both sides of the support frame according to installation requirements. The support frame can be hung inside the water treatment device through the assembly component, or the adjustment rod can be rotated and unscrewed from the end of the support rod away from the support frame until the end of the adjustment rod away from the support rod abuts against the inner wall of the water treatment device, thereby limiting the position of the first cleaning brush assembly and the second cleaning brush assembly inside the water treatment device, so that the first cleaning brush assembly and the second cleaning brush assembly can be flexibly installed.

[0010] Specifically, eight groups of the mounting seats and assembly components are arranged in parallel with each other, and two adjacent groups of the mounting seats at the four corners of the support frame are arranged in a right-angle structure.

[0011] Specifically, a clamping plate for limiting the position of a mounting plate is vertically inserted into the top of each of the first cleaning brush assembly and the second cleaning brush assembly, and two groups of the mounting plate and the clamping plate are relatively parallel.

[0012] Specifically, one end of the screw rod passes through the fixed plate and is rotatably connected to one side of a clamping plate located at the top of the second cleaning brush assembly, and the fixed plate and the clamping plate are arranged relatively parallel.

[0013] Specifically, a slide groove is provided on the upper end surface of the support frame at the position of the slide bar, a limiting groove is provided on the upper end surface of the mounting plate close to the clamping plate, and an arc-shaped clamping groove is also provided on the upper end surface of the mounting plate close to the limiting groove.

[0014] Specifically, a threaded hole for mounting a support rod is provided at one end of the mounting seat away from the support frame, and an adjustment rod is threadedly connected to one end of the support rod away from the mounting seat.

[0015] Beneficial effects of the utility model:
