Description

Technical Field

[0001] The utility model relates to a membrane component for sewage treatment, in particular to a membrane component for sewage treatment, belonging to the technical field of sewage treatment. Background Art

[0002] When using sedimentation tanks for filtration, the water discharged after filtration in the sedimentation tanks is difficult to meet the national sewage treatment discharge standards. Today, membrane treatment technology is gradually maturing, and the type and structure of membrane components play an important role in sewage treatment.

[0003] During the use of membrane components, since the membrane components are in sewage for a long time and filter the sewage, a large amount of silt will accumulate inside the membrane components. In the existing technology, the cleaning of the membrane components is to separate the components one by one and then clean and rinse them separately. This process is labor-intensive and time-consuming. Therefore, we need to upgrade and transform the existing technology. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a membrane component for sewage treatment. The device can realize fast and efficient flushing of the entire membrane component, which solves the technical problem that the cleaning of the membrane component in the prior art is to separate the components one by one and then clean and flush them separately, which is a process with large workload and is extremely time-consuming.

[0005] In order to solve the above problems, the following technical solutions are provided:

[0006] A membrane assembly for sewage treatment is designed, comprising membrane filaments and a supporting bottom, wherein the bottom of the membrane filaments is fixedly connected to a bottom platform, the top of the membrane filaments is fixedly connected to a top platform, the bottom of the bottom platform is sleeved on the top of the supporting bottom, a sliding groove is provided inside the supporting bottom, a connecting pipe is slidably connected inside the sliding groove, both ends of the connecting pipe are fixedly connected to a centralized air pipe, the middle position of the connecting pipe is fixedly connected to an exhaust pipe, and an exhaust port is provided on the outer side of the exhaust pipe.

[0007] Furthermore, a top water outlet is fixedly connected to one end of the side surface of the top platform, a bottom water outlet is fixedly connected to one end of the same side surface of the bottom platform, and the ends of the bottom water outlet and the top water outlet are connected with a centralizing pipe.

[0008] Through the above technical solution, the clean water filtered by the membrane fibers flows out from the water outlets at the upper and lower ends of the membrane fibers, and the clean water at both ends is collected and recycled by the central pipe.

[0009] Furthermore, a support frame is fixedly connected to the top of the support bottom, and two ends of the bottom of the top platform are fixedly connected to the top position of the support frame.

[0010] Through the above technical solution, the support frame can hold the top platform at the top and play a supporting role for the top platform as a whole.

[0011] Furthermore, a connecting inner pipe opening is fixedly connected to the middle position of the side of the centralized air pipe, and a connecting outer pipe opening is sleeved on the outer side of the connecting inner pipe opening.

[0012] Through the above technical solution, since the connecting pipe is a sleeve connection, when the membrane assembly is cleaned, its air inlet pipe can be replaced with a water inlet pipe through the connecting pipe, and then the water flows through the exhaust port to flush the membrane fibers.

[0013] Furthermore, an air inlet pipe is fixedly connected to the top of the connecting outer pipe opening, and one end of the top of the air inlet pipe is an air inlet.

[0014] Through the above technical solution, the connecting pipes are connected to each other, so that the air inside the intake pipe can be pushed into the exhaust pipe through the connecting pipe, and the air is dispersed and discharged from the exhaust port.

[0015] Furthermore, the membrane fibers are made of hollow fiber materials, and rubber layers are provided at the connection points at the upper and lower ends of the membrane fibers.

[0016] The above technical solution can prevent the entry of sewage into the filtered clean water due to insufficient sealing between the two ends of the membrane fibers during the membrane fiber filtration process, thereby preventing the filtered clean water from being contaminated.

[0017] Furthermore, the support bottom and the support frame are made of metal materials with good corrosion resistance, and the top of the support bottom is provided with a connection port that fits with the bottom of the base.

[0018] Through the above technical solution, the fixation of the filter module is ensured, and at the same time, the overall stable support is guaranteed.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. In the utility model, since the connecting inner pipe opening and the connecting outer pipe opening are sleeve-connected, when cleaning is needed, it is only necessary to peel off the connecting outer pipe opening and then inject the cleaning liquid through the connecting inner pipe opening. The cleaning liquid enters the exhaust pipe from the connecting inner pipe opening and is then discharged from the exhaust port on the outside of the exhaust pipe. By increasing the injection water pressure, the exhaust port will discharge a high-speed water flow, and by lifting the centralized air pipe up and down, the membrane assembly membrane wire is flushed as a whole, thereby improving the efficiency of cleaning the module;

[0021] 2. In the utility model, air is injected into the air inlet pipe, and the air enters the exhaust pipe from the air inlet pipe, and then is discharged through the exhaust port on the outside of the exhaust pipe. After the air is discharged at the bottom, a large number of bubbles will be formed at the bottom. The bubbles will be discharged upward under the influence of water pressure, providing dissolved oxygen inside the sewage to promote microbial metabolism. During this period, the bubbles will pass through the membrane filaments, which will have an impact effect on the membrane filaments and reduce a certain amount of sludge adhesion;

[0022] With reference to the following description and drawings, specific embodiments of the present invention are disclosed in detail, indicating the manner in which the principles of the present invention can be adopted. It should be understood that the embodiments of the present invention are not limited in scope.
