Description

Technical Field

[0001] The utility model relates to the field of filter membrane modules, in particular to a single-body immersion filter membrane module. Background Art

[0002] Sewage treatment is a technology that uses physical, chemical, and biological methods to treat wastewater, purify the wastewater, reduce pollution, and achieve wastewater recycling and reuse to make full use of water resources. Common chemicals used in wastewater treatment include flocculants, coagulant aids, and conditioning agents. Treatment technologies include pretreatment, new fillers, ceramic membranes, etc. Among them, sewage filtration belongs to the physical method, usually filtering sewage through a sieve or sieve plate to remove impurities and solid particles to complete the purification of sewage. Currently, many sewage companies use dozens of ultrafiltration membrane modules to set up complete large-scale equipment for filtration.

[0003] However, for some locations such as fish ponds and water tanks where it is inconvenient to move the water source, it is inconvenient to treat the sewage inside. The traditional industrial treatment of submerged ultrafiltration modules or MBR membrane sheet aeration cleaning methods use a continuous small bubble method at the bottom, and the cleaning effect on the sludge and colloid attached to the surface of the filtration module is not good. The membrane flux decays rapidly, and the membrane module or membrane unit is prone to mud accumulation, resulting in frequent chemical assisted cleaning of the system, increasing the system energy consumption and maintenance workload. Content of the Utility Model

[0004] Based on this, the purpose of the present utility model is to provide a single-body immersion filter membrane module to solve the technical problems.

[0005] To achieve the above purpose, the present utility model provides the following technical solution: A single-body immersion filter membrane module, including an upper cover, an aeration box, a base support pipe, and a filtration module. The upper cover, aeration box, base support pipe, and filtration module form the filtration module. A water suction pipe is arranged at the top of the upper cover, and an air inlet pipe is installed on one side of the top of the upper cover. A filtration component is arranged at the bottom of the upper cover, and a support pipe is installed at the bottom of the upper cover. The end of the support pipe is installed with an aeration box, and a base is arranged at the bottom of the aeration box. An aeration groove is opened at the top of the aeration box, and an aeration pipe is arranged on the inner wall of the aeration groove. A circulation groove is opened at the top of the base, and an inner air pipe is installed at the bottom end of the inner wall of the circulation groove. An inner groove is opened at the bottom of the base, and an outer air pipe is fixed at the top end of the inner wall of the inner groove. And through holes are opened at the top of the outer air pipe.

[0006] By adopting the above technical solution, when in use, the filtration module can be directly placed into the sewage, which is convenient for direct use. The base removes the conventional bottom cover, effectively avoiding sludge blockage of the air inlet holes and extending the service life. The base can store 2.0L - 12L of gas at one time and discharge it instantaneously, forming relatively large pulsed bubbles, increasing the bubble flushing force, greatly increasing the jitter of the water flow and the filtration component, effectively separating the sludge attached to the surface of the filtration component during the filtration process, restoring the flux, and thus greatly extending the service life of the filtration component or components.

[0007] The present utility model is further configured such that multiple groups of mounting holes are provided at the bottom of the upper cover and the top of the aeration box, and communication holes are provided at the top of the upper cover, the aeration box, and the base, and the inner wall of the communication hole is fitted with the outer wall of the support pipe.

[0008] By adopting the above technical solution, the support pipe can be conveniently installed through the provided mounting holes, and the support pipe can also be conveniently installed through the provided communication holes. The upper cover, the aeration box, and the base are connected through the support pipe, enabling the gas to enter the interior of the support pipe through the air inlet pipe and then enter the built-in groove at the bottom of the base.

[0009] The present utility model is further configured such that the diameter of the inner air pipe is smaller than that of the outer air pipe, the length of the inner air pipe is smaller than that of the outer air pipe, and the length of the outer air pipe is smaller than the height of the base.

[0010] By adopting the above technical solution, when the gas enters the interior of the inner air pipe, the liquid inside the inner air pipe and the outer air pipe is discharged. When the liquid level is lower than the inner air pipe, the gas will enter the inner air pipe. However, at this time, the liquid level is not lower than the height of the outer air pipe, and bubbles will be formed when the gas enters the aeration pipe through the inner air pipe.

[0011] The present utility model is further configured such that a clamping groove is provided at the bottom of the aeration box, and the inner wall of the clamping groove is fitted with the outer wall of the base.

[0012] By adopting the above technical solution, the clamping of the clamping groove on the outer wall of the base can prevent the gas from flowing out from its connection, thereby increasing the airtightness.

[0013] The present utility model is further configured such that the aeration pipe penetrates through the aeration box and extends to the bottom of the aeration box. A partition plate is fixed to the bottom of the aeration box, and multiple groups of flow - dividing grooves are provided inside the partition plate, and the outer wall of the partition plate is fitted with the inner wall of the flow - through groove.

[0014] By adopting the above technical solution, the fitting of the outer wall of the partition plate with the inner wall of the flow - through groove can prevent the gas from flowing out from the inner wall of the flow - through groove during use, enabling the gas to enter the inner wall of the flow - dividing groove and thus flow out through the aeration pipe.

[0015] The present utility model is further configured such that a plurality of support plates are fixed to the bottom of the upper cover.

[0016] By adopting the above technical solution, the support plates can prevent the filter assembly from moving upward, and a certain space is reserved at the bottom of the upper cover for the filter assembly, which is convenient for pumping water.

[0017] In summary, the present utility model mainly has the following beneficial effects:

[0018] The present utility model is provided with an upper cover, an aeration box, a base, a support pipe and a filter module. When in use, the filter module can be directly placed in sewage, which is convenient for direct use. The base removes the conventional bottom outer cover, effectively avoiding sludge blockage of the air inlet hole and extending the service life. The base can store 2.0L - 12L of gas at one time and discharge it instantaneously, forming relatively large pulsed bubbles, increasing the bubble flushing force, greatly increasing the shaking amount of the water flow and the filter assembly, effectively separating the sludge attached to the surface of the filter assembly during the filtration process, restoring the flux, and thus greatly extending the service life of the filter assembly or the filtration component.
