Description

Technical Field

[0001] The utility model belongs to the technical field of water distributors, and in particular relates to a water distributor structure of an anaerobic reaction tank for sewage treatment. Background Art

[0002] The anaerobic reactor is input with sewage at its bottom, and the sewage passes upward through the sludge bed containing granular sludge or flocculent sludge. The anaerobic reaction occurs in the process of contact between the wastewater and the sludge particles. The biogas produced under the anaerobic state causes internal circulation, which is beneficial to the formation and maintenance of granular sludge. Some gases formed in the sludge layer are attached to the sludge particles. After the bubbles are released, the sludge particles will settle to the surface of the sludge bed, and the attached and unattached gases are collected in the gas collecting chamber at the top of the reactor. At present, common anaerobic reactors on the market will have a water distributor at the bottom to achieve uniform water distribution.

[0003] However, there are some problems with the prior art: during the use of the water distributor, water is sprayed out after passing through its interior, but the water source is often mixed with impurities. Some larger impurities can easily flow along the water to block the spray holes on the water distributor, thereby affecting the uniformity of water distribution. Therefore, we propose a water distributor structure for an anaerobic reactor for sewage treatment. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of the utility model is to provide a water distributor structure for an anaerobic reaction tank for sewage treatment, which blocks impurities by setting a filter screen, thereby avoiding clogging of the spray hole.

[0005] The utility model is implemented as follows: a water distributor structure of an anaerobic reaction tank for sewage treatment comprises a flange, a round tube is fixedly mounted on the flange, a transfer sleeve is fixedly sleeved on the round tube, a through hole is provided on the surface of the transfer sleeve, a connecting pipe located outside the through hole is fixedly mounted on the surface of the transfer sleeve, a transverse pipe is threadedly sleeved on the inner wall of the connecting pipe, a spray hole is provided on the transverse pipe, a frame is provided on the inner wall of the transverse pipe, a filter screen is fixedly mounted on the frame, and the frame and the transverse pipe are connected by a limiting mechanism.

[0006] Optionally, a slot is formed on the inner wall of the transverse tube, a notch is formed on the frame, the limiting mechanism comprises a latch which is movably inserted into the notch and the top of the latch extends into the slot, and a pressure plate is connected to the latch.

[0007] Optionally, a spring is fixedly connected to the bottom of the latch, and the other end of the spring is fixedly connected to the inner wall of the slot.

[0008] Optionally, the inner wall of the connecting pipe is provided with a flange, and a gasket is fixedly mounted on the flange.

[0009] Optionally, a blocking column is fixedly mounted on the inner wall of the through hole, and the blocking column is configured to be cylindrical.

[0010] Optionally, a conduit located outside the spray hole is fixedly mounted on the surface of the transverse tube, and the conduit outside is arranged in an inclined shape.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The utility model provides a filter screen. During use, after water flows into the transverse pipe, it will continue to flow through the filter screen, while impurities in the water will be blocked by the filter screen, preventing the impurities from flowing to the position near the spray hole, thereby preventing the spray hole from being blocked. In addition, the staff can also remove the frame and the filter screen from the inside of the transverse pipe through the limiting mechanism, which is convenient for cleaning or replacing the filter screen.

[0019] In order to further understand the content, features and effects of the utility model, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0020] like Figures 1 to 4As shown, an embodiment of the utility model provides a water distributor structure of an anaerobic reaction tank for sewage treatment, comprising a flange 1, a round pipe 2 is fixedly mounted on the flange 1, a switching sleeve 3 is fixedly sleeved on the round pipe 2, a through hole 4 is provided on the surface of the switching sleeve 3, a connecting pipe 5 located outside the through hole 4 is fixedly mounted on the surface of the connecting pipe 3, a transverse pipe 6 is threadedly sleeved on the inner wall of the connecting pipe 5, a spray hole 7 is provided on the transverse pipe 6, a frame 8 is provided on the inner wall of the transverse pipe 6, a filter screen 9 is fixedly mounted on the frame 8, and the frame 8 and the transverse pipe 6 are connected by a limiting mechanism.

[0021] Furthermore, a slot 10 is provided on the inner wall of the transverse tube 6, a notch 11 is provided on the frame 8, and the limiting mechanism includes a latch 12, which is movably inserted in the notch 11 and the top of the latch 12 extends to the inside of the slot 10, and a pressing plate 13 is connected to the latch 12. When the top of the latch 12 is located inside the slot 10, the frame 8 can be limited so that the frame 8 is stably maintained inside the transverse tube 6, and when the top of the latch 12 is pulled out from the inside of the slot 10, the frame 8 can be driven by the filter 9 to be taken out from the inside of the transverse tube 6.

[0022] Furthermore, a spring 14 is fixedly connected to the bottom of the latch 12, and the other end of the spring 14 is fixedly connected to the inner wall of the slot 11. By setting the spring 14 to a compressed state, the elastic force of the spring 14 will generate a thrust on the latch 12, so that the top of the latch 12 is stably maintained inside the slot 10.

[0023] Furthermore, the inner wall of the connecting pipe 5 is provided with a flange 15, and a gasket 16 is fixedly mounted on the flange 15. The gasket 16 can be made of rubber, and when the cross pipe 6 is screwed into the connecting pipe 5, the gasket 16 is squeezed, and because the rubber is elastic, a rebound force is generated when squeezed, so that the cross pipe 6 and the gasket 16 are closely fitted, thereby improving the sealing between the connecting pipe 5 and the cross pipe 6.

[0024] Further, a blocking column 17 is fixedly installed on the inner wall of the through hole 4, and the blocking column 17 is set to a cylindrical shape. Through the design of the blocking column 17, the water flow can be divided before the water flow enters the horizontal pipe 6, thereby reducing the impact force of the water flow on the filter screen 9.

[0025] Furthermore, a conduit 18 located outside the spray hole 7 is fixedly mounted on the surface of the transverse pipe 6, and the outer conduit 18 is arranged in an inclined shape. By designing the outer conduit 18 in an inclined shape, the water flow spraying range can be increased and the water distribution effect can be improved.

[0026] During use, water flows into the interior of the adapter sleeve 3 through the circular tube 2, and then enters the interior of the transverse tube 6 from the through hole 4. Due to the design of the blocking column 17, the water flow can be divided before the water flow enters the transverse tube 6, thereby reducing the impact force of the water flow on the filter screen 9. After the water flow enters the transverse tube 6, it will continue to flow through the filter screen 9, and the impurities in the water will be blocked by the filter screen 9 to prevent the impurities from flowing to the position near the spray hole 7, thereby not clogging the spray hole 7. The water flows out through the conduit 18. When the staff needs to clean or replace the filter screen 9, they can first unscrew the transverse tube 6 from the connecting pipe 5, and then press the pressure plate 13 downward to make the pin 12 move downward and compress the spring 14. When the top of the pin 12 is removed from the inside of the slot 10, the limiting effect on the frame 8 is released, so that the frame 8 and the filter screen 9 can be taken out from the inside of the transverse tube 6, and then the filter screen 9 can be cleaned or replaced.

[0027] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
