Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a pool bottom desilting structure and an MBR membrane cleaning pool. Background Art

[0002] Sewage treatment MBR membrane is a new type of sewage treatment technology. It uses membrane filtration technology in bioreactors to achieve solid-liquid separation, thereby realizing the sewage treatment process. It has the advantages of high treatment efficiency, good effluent quality, small footprint, stable operation, and simple operation. Therefore, it is widely used in urban sewage treatment, industrial wastewater treatment and other fields. However, after a period of operation, the sewage treatment MBR membrane is prone to form bacterial flocs and biofilms, so it is usually necessary to clean the inside of the MBR membrane pool regularly.

[0003] In the prior art, the bottom of the MBR membrane pool is a flat structure with only a top inspection access. When cleaning the bottom sludge generated by cleaning the MBR membrane, fresh air must first be delivered into the tank to detect the gas composition and content inside the tank; then, manual entry is made into the tank through the top inspection access, and the internal sludge is manually handled with tools. Finally, the sludge is sorted and bagged and transported out through the top inspection access. Manual cleaning is not only inefficient, but also the internal sludge will produce harmful gases such as hydrogen sulfide after long-term accumulation, posing a great safety risk. Utility Model Content

[0004] In order to solve the above problems, the first aspect of the utility model provides a pool bottom dredging structure, comprising:

[0005] A cleaning container, and a flushing component and a dredging component arranged in the cleaning container;

[0006] Wherein, the bottom of the cleaning container is an inclined supporting surface;

[0007] The flushing assembly includes a water supply pipe, and a spray head and a switch arranged on the water supply pipe;

[0008] One end of the water delivery pipe is transversely arranged at the higher side of the cleaning container, the switch is arranged outside the cleaning container, the water delivery pipe is used to deliver high-pressure water flow, the switch is used to control the flow state of the high-pressure water flow in the water delivery pipe, and the nozzle is arranged at one end of the water delivery pipe located in the cleaning container;

[0009] The dredging assembly is located at a lower side of the cleaning container, and the dredging assembly comprises a dredging trough.

[0010] In some embodiments, the dredging assembly further comprises a dredging plate disposed in the dredging trough, and the cleaning container is provided with a cleaning port adapted to the dredging trough.

[0011] In some embodiments, a guide rod is provided in the dredging trough along the length direction, and the guide rod is slidably connected to the dredging plate.

[0012] In some embodiments, the dredging trough is arranged parallel to the water supply pipe.

[0013] A second aspect of the utility model provides an MBR membrane cleaning pool, comprising a pool bottom desilting structure according to any one of the above-mentioned schemes.

[0014] By adopting the above technical solution, the utility model mainly has the following technical effects:

[0015] By setting the supporting surface at an angle, the sludge generated by cleaning the MBR membrane is flushed into the silt removal tank using the flushing component and finally pushed out through the silt removal plate. This solves the technical problems of low efficiency and great safety risks of manual cleaning, and achieves the technical effect of automatically cleaning the sludge at the bottom of the pool.

[0024] Embodiment 1

[0025] See also Figure 1-Figure 2 The first aspect of the utility model provides a pool bottom dredging structure. When in actual use, the pool bottom dredging structure is located in the MBR membrane cleaning pool, and includes: a cleaning container 1, and a flushing component 2 and a dredging component 3 arranged in the cleaning container 1.

[0026] In some embodiments, the cleaning container 1 is a place for accommodating the MBR membrane for cleaning. For example, the cleaning container 1 can be a box structure made of metal materials, or a pool structure built with building materials. By placing the MBR membrane cleaning equipment in the cleaning container 1, the MBR membrane is cleaned in the cleaning container 1 using the MBR membrane cleaning equipment, and finally the sludge cleaned from the MBR membrane is recovered and cleaned.

[0027] In some preferred embodiments, the bottom of the cleaning container 1 is an inclined support surface 11, and the support surface 11 is used to place the MBR membrane cleaning equipment. In some embodiments, the MBR membrane cleaning equipment is placed in the middle of the cleaning container 1. By arranging the flushing component 2 on the higher side of the cleaning container 1, the sludge is flushed to the lower side of the cleaning container 1 by utilizing the flushing effect of the flushing component 2.

[0028] Furthermore, the flushing component 2 includes a water supply pipe 21, and a nozzle 22 and a switch 23 arranged on the water supply pipe 21, wherein one end of the water supply pipe 21 is transversely arranged on the higher side of the cleaning container 1, and the switch 23 is arranged outside the cleaning container 1. The water supply pipe 21 is used to deliver high-pressure water flow, and the switch 23 is used to control the passage state of the high-pressure water flow in the water supply pipe 21. The nozzle 22 is arranged at one end of the water supply pipe 21 located in the cleaning container 1, and the high-pressure water flow delivered by the water supply pipe 21 flushes the sludge in the cleaning container 1 to the lower side of the cleaning container 1 through the nozzle 22.

[0029] Furthermore, the dredging component 3 is located on the lower side of the cleaning container 1, and is used to clean the sludge in the cleaning container 1 to the outside of the cleaning container 1. In some embodiments, the dredging component 3 includes a dredging trough 31, and a dredging plate 32 arranged in the dredging trough 31, and the cleaning container 1 is provided with a cleaning port 12 adapted to the dredging trough 31.

[0030] In some embodiments, the silt removal trough 31 is a hollow container without a top cover, and the silt removal trough 31 is arranged parallel to the water supply pipe 21. The sludge in the cleaning container 1 will enter the silt removal trough 31 under the flushing action of the high-pressure water flow in the water supply pipe 21, and finally, the silt in the cleaning container 1 can be removed to the outside of the cleaning container 1 by cleaning the silt in the silt removal trough 31.

[0031] Furthermore, the silt cleaning plate 32 is adapted to the silt cleaning trough 31. In some embodiments, a guide rod 33 is provided in the silt cleaning trough 31 along the length direction. The guide rod 33 is slidably connected to the silt cleaning plate 32. The silt cleaning plate 32 can be driven to slide in the silt cleaning trough 31 by connecting a telescopic device to the silt cleaning plate 32, and the silt cleaning plate 32 can be driven to slide in the silt cleaning trough 31 by the telescopic device, so that the silt in the silt cleaning trough 31 can be pushed out of the cleaning container 1 through the cleaning port 12, thereby achieving the technical effect of automatically cleaning the silt at the bottom of the pool.
