Membrane module device for sewage treatment

Abstract

The invention discloses a membrane module device for sewage treatment. The membrane module device comprises a connection terminal, wherein a water inlet is fixedly formed in the upper end of the connecting terminal, the lower end of the connecting terminal is rotationally connected with a guide pipe through a threaded groove, ball bearings are fixedly arranged at the upper end and the lower end ofthe guide pipe, a rolling barrel is movably installed on one side of the guide pipe through the ball bearings, and comprises a first half rolling barrel and a second half rolling barrel, plural setsof clamping grooves are formed in one side surface, close to the second half rolling barrel, of the first half rolling barrel, and plural sets of buckles are fixedly arranged on one side surface, close to the first half rolling barrel, of the second half rolling barrel. According to the invention, the membrane module device is practical, simple in structure and convenient to use; and a filtering screen, a first filtering membrane and a second filtering membrane are arranged into a semi-cylinder structure, and the semi-cylinder structure is installed in the detachable rolling barrel, so that the filtering device can be conveniently cleaned after operation, the filtering surface of the device is greatly improved, the overall design of the device is reasonable, and the market requirement is met.

Problems solved by technology

[0002] In the process of daily life, industrial manufacturing, urban construction, etc., water is widely used as the most common medium, but the disadvantages that come with the use process are the sewage after use. Sewage is generally caused by some soluble and insoluble Soluble impurities are doped in pure water so that it does not meet the requirements for use. Reasonable treatment of sewage is not only to protect the environment, but also a good treatment method can turn waste into treasure. Devices with filtering effects during the treatment process are especially It is widely used, and the membrane module that plays a filtering role is more popular

[0003] Deficiencies in the prior art: 1. Traditional membrane devices generally fix and install membrane materials with filtration and adsorption functions inside the conduits for water conduction. During the filtration process, a large amount of impurities in sewage will be filtered and adsorbed by the membrane materials. , so as to reduce the content of impurities in sewage, but as the use of aging increases, a large amount of impurities will accumulate on the surface of the membrane material. The accumulated impurities will not only reduce the permeability of the membrane material, but also cause the filter membrane Damaged, the way of fixed installation makes the device difficult to clean and extremely inconvenient to use

[0004] 2. When the traditional membrane unit is used, the membrane unit is installed inside the conduit, and one end of the conduit pumps the sewage into the membrane unit for filtration, and because of the connection between the pump and the conduit, it plays a filtering role. The membrane material can only be fixed and installed in the form of a cross-section of the conduit, and the filtration efficiency of the installed membrane unit can only be changed by the size of the cross-section of the conduit or the strength of the water pressure, but the conduit with an excessively large cross-section is inconvenient to install during use. Excessive water pressure will lead to incomplete filtration of sewage, and will also increase the negative pressure of the membrane group, making it easy to damage
