Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a filter tank of a biological deodorization device. Background Art

[0002] Malodorous gas is a gas that has a great pollution and impact on the environment. It is usually emitted by pollutants. After inhaling malodorous gas, the human body is prone to central nervous system disorders, lesions and other phenomena. Long-term exposure to malodorous gas environment is also prone to chronic diseases. Therefore, it is necessary to deodorize the malodorous gas. Biological deodorization refers to the use of microbial physiological metabolism to transform odorous substances so that the target pollutants are effectively decomposed and removed. The raw materials that emit malodorous gas are sent to the biological device, and the raw materials are degraded by microorganisms attaching to them so that they can no longer emit malodorous gas, thereby achieving the purpose of deodorization. The filter tank of the biological deodorization device can effectively decompose the liquid malodorous gas raw materials, thereby reducing organic pollutants while greatly reducing the emission of malodorous gas. The treatment effect is good and the harm to the environment is extremely small.

[0003] Although the above-mentioned prior art can solve the corresponding technical problems, it still has certain defects: the existing deodorization device filter uses multiple microbial membranes to make the passing malodorous sewage contact with the microbial membranes, but the microbial membranes need to be replaced after a period of use to clean the attachments on the microbial membranes, such as mud and sand, and the top cover of the filter needs to be opened during cleaning, which can easily lead to the malodorous gas in the filter tank being dissipated outward during the process of cleaning and removing the microbial membrane, causing adverse effects on the environment around the filter tank, and the malodorous gas is easily inhaled by the cleaning construction workers, which is not conducive to the health of the cleaning construction workers. Utility Model Content

The microbial membrane includes a membrane body detachably inserted into the bottom surface of the inner wall of the holding tank and a closed extraction block slidably arranged on the top side wall of the membrane body and detachably penetrated and arranged on the closing cover. When the membrane body is extracted, it passes through the closed extraction block and the outside world is kept isolated from the inside of the holding tank during the removal process.

[0006] A further improvement is that: the bottom of the membrane body is also provided with an anti-slip column which is detachably embedded in the bottom surface of the inner wall of the containing pool.

[0008] A further improvement is that: a movable cavity is provided in the membrane body, and movable blocks are connected to the upper and lower surfaces of the inner walls of the movable cavity.

[0009] A further improvement is that the closed pull-out block comprises a detachable connecting block penetratingly arranged in the closing cover and a fitting block arranged in the connecting block, and an elastic closing sheet is arranged between the bottom inner wall of the connecting block and the bottom outer wall of the fitting block.

[0010] A further improvement is that a plurality of pressure columns are provided between the outer wall of the fitting block and the inner wall of the connecting block. The pressure columns include a pressure column provided on the outer wall of the fitting block and a groove block provided on the inner wall of the connecting block and slidably connected to the outer wall of the pressure column. A pressure spring is provided between the inner wall of the groove block and the end of the pressure column.

[0014] After adopting the above technical scheme, the beneficial effect of the utility model is as follows: when the membrane body of the microbial membrane is replaced or cleaned, the membrane body can be pulled out along the closed withdrawal block by pulling up the membrane body. During the withdrawal process, the bonding blocks of the closed withdrawal block are always bonded and sealed with both sides of the membrane body, thereby maintaining the isolation effect between the outside world and the inner cavity of the containing tank, and the bonding blocks are bonded together after withdrawal to ensure isolation at the same time, thereby avoiding the malodorous gas in the containing cavity from dispersing outward during the process of extracting the membrane body, ensuring the surrounding environmental hygiene, and preventing the malodorous gas from harming the health of the cleaning construction workers.

When in use, the odor is removed. The sewage is sent into the holding tank 1 through the water inlet pipe 2, and is fully contacted with the membrane body 41 of the microbial membrane 4, so that the organic matter that produces the foul smell is fully decomposed, and then becomes odorless liquid and is discharged from the outlet pipe 3. After a period of use, an adhesion layer will be generated on the membrane body of the microbial membrane 4. During the removal and cleaning process, the membrane body 41 is first lifted upward along the closed extraction block 44. At this time, the outer wall of the membrane body 41 will contact the fitting block 52, and in the process of extraction, the elastic sealing Under the elastic pressure of the closing piece 56, the laminating block 52 always maintains the laminating effect with the membrane body 41, and no odor will leak out between the membrane body 41 and the laminating block 52 during the extraction process. After the membrane body 41 is extracted, the laminating block 52 can be made to fit each other under the action of the elastic closing piece 56 to completely seal the opening, so that the odor will not leak out, thereby preventing the malodorous gas in the accommodating chamber 1 from emanating outwards during the extraction process of the membrane body 41, thereby ensuring the surrounding environmental hygiene and preventing the malodorous gas from harming the health of the cleaning workers.

[0022] The bottom of the membrane body 41 is also provided with an anti-detachment column 42 which is detachably embedded in the bottom surface of the inner wall of the holding tank 1, which is conducive to making the connection of the membrane body 41 more stable after being inserted into the holding tank 1;

During the removal and cleaning process, the membrane body 41 is first lifted upward along the closed extraction block 44. At this time, the outer wall of the membrane body 41 will contact the fitting block 52 and During the separation process, the elastic pressure of the elastic sealing sheet 56 keeps the fitting block 52 in contact with the membrane body 41 at all times, so that no odor will leak out between the membrane body 41 and the fitting block 52 during the separation process. After the membrane body 41 is separated, the fitting block 52 can be fitted together under the action of the elastic sealing sheet 56 to completely seal the opening, so that the odor will not leak out, thereby avoiding the malodorous gas in the accommodating chamber 1 from dispersing outward during the separation process of the membrane body 41, thereby ensuring the surrounding environmental hygiene and preventing the malodorous gas from harming the health of the cleaning construction workers.
