Description

Technical Field

[0001] This utility model relates to a water treatment device, and more particularly to an MBR membrane device. Background Technology

[0002] MBR, also known as membrane bioreactor, is a novel water treatment technology that combines membrane separation units with biological treatment units. Currently, MBR wastewater treatment processes are increasingly widely used. However, in traditional MBR membrane devices, the fixed end 101 of the water collection pipe is typically fixed to the membrane frame 100 using stainless steel U-shaped pipe clamps 103 and locking nuts 113. Figure 1 and Figure 2 As shown, although its purchase cost is low, only about 2.5-3 yuan, installation requires a professional electric wrench and is time-consuming and labor-intensive. For example, for a 50-membrane MBR membrane unit, it takes about 2 people 4 hours to install the water collection pipe fixed end onto the membrane frame using U-shaped pipe clamps and locking nuts. Utility Model Content

[0003] To address the aforementioned problems in the prior art, this invention provides an advantageous MBR membrane device that features rapid direct insertion assembly and is designed to prevent detachment.

[0004] To achieve the above objectives, this utility model provides an MBR membrane device, including an MBR membrane frame, multiple MBR membrane elements, and multiple water collection pipes, characterized in that the fixed end of each water collection pipe is directly inserted and fixed to the MBR membrane frame.

[0005] Furthermore, the MBR membrane frame has an external mounting beam with a straight insertion hole. The fixed end of the water collection pipe is fixed to the MBR membrane frame by passing through the straight insertion hole on the external mounting beam via a straight insertion tube, wherein the straight insertion tube and the fixed end of the water collection pipe are interference-fitted.

[0006] Furthermore, the straight insertion tube is also provided with a radial locking hole, which is located on the inner side of the outer mounting crossbeam, and the anti-reverse cotter pin is inserted into the radial locking hole.

[0007] Furthermore, the straight-insertion pipe is made of chemical-grade UPVC pipe; the anti-reverse cotter pin is made of stainless steel.

[0008] Furthermore, the straight insertion tube is also provided with a radial locking hole on the outside of the outer mounting beam for inserting a locking cotter pin.

[0009] Furthermore, the water collection pipe also has a product water end opposite to its fixed end, which is also directly inserted and fixed to the MBR membrane frame.

[0010] Furthermore, the MBR membrane frame also has an inner mounting beam with a straight insertion hole. The permeate end is fixed to the MBR membrane frame by passing through the straight insertion hole on the inner mounting beam via a straight insertion tube. A sealing ring is provided between the straight insertion tube and the permeate end.

[0011] This invention has the following advantages over the prior art:

[0012] 1) Free yourself from the constraints of specialized power tools, and eliminate the need to consider the impact of bolt preload on the fixed ends of the water collection pipe and the water production pipe, and consequently on the fixed ends of the MBR membrane elements;

[0013] 2) Direct insertion fixing is convenient, time-saving, and labor-saving, increasing efficiency by 3 times;

[0014] 3) The cotter pins secure the water collection pipe, preventing the fixed end from falling off and thus preventing the MBR membrane element from falling off; it also enables rapid replacement of individual membrane elements.

[0015] 4) The direct insertion fixing method ensures that the membrane element's product outlet and the water collection pipe are at the same elevation, reducing the membrane frame height by 80mm and creating favorable conditions for on-site installation of the membrane frame, as well as for the membrane tank liquid level.

[0016] These and other aspects of the present invention will be more clearly illustrated by referring to the embodiments described below. Attached Figure Description
