Description

Technical Field

[0001] The utility model relates to an interception device, in particular to an MBBR suspended filler suspended interception device, belonging to the technical field of water treatment. Background Art

[0002] MBBR filler is a microbial membrane carrier used in the MBBR process, mainly to provide a suitable environment for the growth of microorganisms. MBBR process technology is to add suspended microbial membrane carriers in the activated sludge system. A large number of biofilms attached and grown on the suspended biofilm carriers greatly increase the active biomass in the biological pool. At the same time, due to the protective effect of the suspended biofilm carrier on microorganisms, the system's ability to resist shock loads is greatly improved. Since the specific gravity of the added suspended filler is close to that of water, the filler is in a suspended fluidized state in the biochemical pool.

[0003] Therefore, the suspended filler will flow out with the effluent, and a filler interception device should be set at the outlet of the biochemical pool. At present, the interception screen in the MBBR process generally fixes the filter at the outlet to intercept the suspended biofilm carrier in the biochemical pool to avoid the loss of filler. The change of the floating or sinking state of the filler is easy to accumulate on one side of the filter, which can easily cause blockage and flooding, affect the working speed of the water treatment system, and even cause interruption of flow. Utility Model Content

DETAILED DESCRIPTION

[0023] The embodiment of the utility model provides a MBBR suspended filler suspension interception device.

[0024] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 , including a biochemical pool 1, one side of the biochemical pool 1 is fixedly connected to a guide box 4, one side of the guide box 4 is provided with a plurality of drainage grooves 5, the plurality of drainage grooves 5 are provided with plate-shaped filter screens 7, both sides of the plate-shaped filter screens 7 are provided with filter screen tubes 6 and sealing plates 8, one side of the plurality of sealing plates 8 is fixedly connected to a control board 9, one side of the plurality of control boards 9 is fixedly connected to a rubber sheet 12, the plurality of rubber sheets 12 are increasingly farther from the biochemical pool 1 from top to bottom, one side of the plurality of rubber sheets 12 is provided with a contact plate 15, and a telescopic pneumatic cylinder 17 is provided between the plurality of contact plates 15

[0025] When the utility model is in use, a bottom pad 3 is fixedly connected to the bottom of the inner cavity of the biochemical pool 1, and the bottom pad 3 controls the difference between the lowest water level inside the biochemical pool 1 and the drainage channel 18 fixed at the bottom of one side of the biochemical pool 1. A water inlet channel 2 is fixedly connected to the top of the biochemical pool 1, and sewage is pumped into the biochemical pool 1 through the water inlet channel 2 for treatment.

[0026] A guide box 4 is fixedly connected to one side of the biochemical pool 1, and a plurality of drainage grooves 5 are sequentially opened on one side of the guide box 4 from top to bottom, so that the water inside the biochemical pool 1 can enter the guide box 4 from the plurality of drainage grooves 5, and the water is discharged through the drainage channel 18 under the guidance of the guide box 4, and a plate-shaped filter screen 7 is arranged inside the plurality of drainage grooves 5, and the filter screen tube 6 arranged on one side of the plate-shaped filter screen 7 is fixedly connected to the guide box 4 like the plate-shaped filter screen 7. Therefore, the water inside the biochemical pool 1 can enter the guide box 4 only after being filtered and intercepted by the plurality of filter screen tubes 6 and the plurality of plate-shaped filter screens 7 to retain the suspended fillers. By arranging a plurality of drainage grooves 5, a plurality of plate-shaped filter screens 7 and a plurality of filter screen tubes 6 on one side of the drainage channel 18, the working burden of a single plate-shaped filter screen 7 is reduced, and the plate-shaped filter screen 7 is prevented from being blocked by the suspended fillers, resulting in slow drainage or interruption of the drainage channel 18. In addition, the filter mesh tube 6 is set at an angle, so after the water level drops, the suspended fillers retained by the plate-shaped filter mesh 7 and the filter mesh tube 6 will not move synchronously with the water, thereby avoiding the situation in which most of the suspended fillers accumulate on one side of a plate-shaped filter mesh 7 in the final stage of drainage inside the biochemical pool 1, thereby avoiding the possibility of the plate-shaped filter mesh 7 being blocked.

[0027] In addition, a sealing plate 8 can be provided on one side of the inner part of the plurality of drainage grooves 5, so that the sealing plate 8 and the filter mesh tube 6 sandwich the plate-shaped filter mesh 7, and at this time, the sealing plate 8 plays the effect of sealing the inner part of the guide box 4. The telescopic pneumatic cylinder 17 fixedly connected to the outer side of the biochemical pool 1 is controlled to work, and the telescopic pneumatic cylinder 17 works to push the fixed curved rod 16 fixedly connected to the extension end to move, and one end of the fixed curved rod 16 is fixedly connected to the transmission plate 14, and the plurality of contact plates 15 are fixedly connected to the transmission plate 14, so when the fixed curved rod 16 moves, it will drive the plurality of contact plates 15 to move synchronously through the transmission plate 14.

[0028] The telescopic pneumatic cylinder 17 is controlled to stop working after working for a period of time, and one end of the control panel 9 extends to the outside of the biochemical pool 1. The rubber sheet 12 fixedly connected to one side of the control panel 9 is arranged on the outside of the biochemical pool 1, and the multiple rubber sheets 12 are farther and farther away from the biochemical pool 1 from top to bottom. When the multiple contact plates 15 move, the first contact plate 15 on the top first contacts with the first rubber sheet 12 on the top, pushing the rubber sheet 12 to move synchronously, so that the rubber sheet 12 drives the control panel 9 to move, and the moving control panel 9 drives the sealing plate 8 to leave the inside of the biochemical pool 1. At this time, the inside of the first drainage groove 5 on the top loses the blocking seal of the sealing plate 8.

[0029] During the operation of the telescopic air cylinder 17, only the first rubber sheet 12 at the top is pushed, so only the first sealing plate 8 at the top moves while the other sealing plates 8 do not move, so at this time, a part of the interior of the biochemical pool 1 enters the interior of the guide box 4 through the first drainage groove 5 at the top, and when the internal water level of the biochemical pool 1 drops to the bottom of the first drainage groove 5 at the top, water cannot enter the drainage groove 5. At this time, a part of the water has been filtered by the plate filter 7 and discharged, and the suspended filler is intercepted by the plate filter 7 and stored in the inclined filter tube 6.

[0030] Then the telescopic pneumatic cylinder 17 is controlled to work for a period of time for the second time and then stop working. At this time, the second contact plate 15 on the top pushes the second rubber sheet 12 on the top to move, and the second control plate 9 on the top moves. The control plate 9 drives the sealing plate 8 inside the second drainage groove 5 on the top to leave, so that a part of the inside of the biochemical pool 1 is discharged through the opened drainage groove 5. At this time, the movement of the first control plate 9 on the top reaches the limit and cannot move, so the force applied by the contact plate 15 to the rubber sheet 12 causes the rubber sheet 12 to deform, and the contact plate 15 passes over the rubber sheet 12, so the movement of the contact plate 15 is not restricted, and the movement of the transmission plate 14 is also not restricted.

[0031] Subsequently, the telescopic pneumatic cylinder 17 is controlled to work for the third, fourth and fifth times for a period of time and then stop working, so that the drainage grooves 5 at multiple levels are opened in turn to discharge the water inside the biochemical pool 1 in sections. Multiple plate-shaped filter screens 7 and filter screen tubes 6 intercept and store suspended fillers in the water, which can avoid the blockage of the drainage channel 18 and ensure the speed of sewage treatment.

[0032] A mounting groove 10 is provided on the top of the control panel 9, and a spring 11 is provided inside the mounting groove 10, and one end of the spring 11 is fixedly connected to the control panel 9, and the other ends of the plurality of springs 11 are fixedly connected to the U-shaped plate 13 fixed to the biochemical pool 1. Therefore, in the early stage when the contact plate 15 pushes the rubber sheet 12, the rubber sheet 12 will drive the control panel 9 to move, and the spring 11 will shrink under the force. When the contact plate 15 passes over the deformed rubber sheet 12, the rebounding spring 11 pushes the control panel 9 to reset, so that the control panel 9 pushes the sealing plate 8 back to the inside of the drainage groove 5, so as to prevent the suspended filler stored in the filter mesh tube 6 from returning to the inside of the biochemical pool 1 during the drainage process after water enters the inside of the guide box 4, so as to prevent the suspended filler stored in the filter mesh tube 6 from returning to the inside of the biochemical pool 1 during the drainage process.

[0033] When the telescopic pneumatic cylinder 17 works to drive the transmission plate 14 and the contact plate 15 to reset, the multiple control plates 9 are reset under the action of the contact plate 15 and the spring 11.

[0034] When the interior of the biochemical pool 1 is filled with water again, the suspended filler stored in the filter mesh tube 6 is submerged in the water and suspended in the water, and the water is stirred, so that the suspended filler is diffused into the interior of the biochemical pool 1 again.

[0035] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
