AI Technical Summary
Existing rapid fermentation biological bacteria screening devices for sewage treatment suffer from filter hole blockage due to the inability to effectively remove biological bacteria accumulated inside the sieve plate, impairing the filtering efficiency.
A device with a sieve plate that vibrates through a pendulum mechanism driven by a rotating shaft and pulley system, combined with a reciprocating motion mechanism, ensures the sieve plate's surface and filter holes are cleared of accumulated bacteria, preventing clogging.
The vibration of the sieve plate effectively disperses surface bacteria and clears blockages in filter holes, maintaining optimal filtering performance and ensuring continuous, efficient screening.

Abstract
Description
Technical Field

[0002] At present, the microbial flora is composed of multiple genera and multiple microorganisms of three major groups, namely photosynthetic fungi, lactic acid bacteria and yeasts. The above-mentioned aerobic and anaerobic microorganisms are mixed and cultured through a fermentation process. Each microorganism produces useful substances and their secretions during its growth process, forming a matrix and raw materials for mutual growth. Through mutual symbiosis and proliferation, a biological flora with a stable structure and wide range of functions and a variety of microbial communities is formed. The existing biological flora needs to be placed in a fermentation tank for fermentation first, and then the fermented biological flora is transported to a screening barrel for screening.
[0003] The existing rapid fermentation biological bacteria continuous screening device for sewage treatment (publication number: CN212955093U) has at least the following disadvantages:
[0004] When the above patent is in use, the L-shaped rod is set so that when the sieve plate rotates along with the third rotating shaft, the powdered biological bacteria on the surface can be scraped by the L-shaped rod to prevent the biological bacteria from being blocked inside the sieve plate. Since the sieve plate cannot vibrate, the biological bacteria on the surface of the sieve plate can only be scraped by the L-shaped rod, but the biological bacteria inside the filter holes of the sieve plate cannot be removed, resulting in blockage of the filter holes and affecting the subsequent filtering effect of the powdered biological bacteria.

An opening is formed through the upper surface of the workbench 1. A sieve plate 5 is slidably mounted on the inner wall of the opening. The sieve plate 5 is inclined. A discharge trough 7 is fixedly mounted on the lower surface of the workbench 1. The discharge trough 7 is arranged below the opening. A rotating shaft 10 is rotatably mounted between the inner walls of the discharge trough 7. A rotating disk 11 is fixedly mounted on the outer surface of the rotating shaft 10. The inner walls of the rotating disk 11 are equidistantly rotatably mounted. There are multiple pendulums 12, which are against the lower surface of the screen plate 5. The workbench 1 is also provided with a motion mechanism that drives the rotating shaft 10 to rotate. The motion mechanism includes a first pulley 18 fixedly installed on the outer surface of another support plate 13. The other end of the crankshaft 14 passes through the outer surface of the support plate 13 and is fixedly installed with the rotation center of the first pulley 18.

The outer surfaces of the first pulley 18 and the second pulley 19 are provided with belts 20.
[0027] The crankshaft 14 drives the first pulley 18 to rotate, so that the first pulley 18 drives the second pulley 19 to rotate through the belt 20, and the second pulley 19 drives the rotating shaft 10 to rotate, so that the rotating shaft 10 drives the turntable 11 to rotate, and the turntable 11 drives the pendulum 12 to move, and the lower surface of the sieve plate 5 is struck by the pendulum 12 to vibrate the sieve plate 5. The vibration of the sieve plate 5 can disperse the biological bacteria on the surface of the sieve plate 5. At the same time, the filter holes of the sieve plate 5 are vibrated, so that the biological bacteria powder accumulated inside the sieve plate 5 can fall off. The device facilitates the vibration of the sieve plate 5 to avoid clogging inside the filter holes on its surface, thereby ensuring the filtering effect of the sieve plate 5.
[0028] In this embodiment, two dovetail grooves 9 are symmetrically provided on the upper surface of the workbench 1, and two dovetail rails 21 are symmetrically fixedly installed on the lower surface of the screen plate 5. The two dovetail rails 21 are respectively slidably installed with the inner walls of the two dovetail grooves 9.

[0029] When in use, the fermented biological bacteria raw materials are sent to the upper surface of the sieve plate 5 through the material transport device, and the crankshaft 14 is driven to rotate by the driving motor 17, so that the crankshaft 14 drives the curved neck 15 to move eccentrically, and the curved neck 15 drives the connecting rod 16 to move, so that the connecting rod 16 drives the sieve plate 5 to move back and forth along the dovetail slide 9.

The pendulum 12 strikes the upper surface of the discharge trough 7 to vibrate it, so that the biological bacteria powder falling on the upper surface of the discharge trough 7 can flow more smoothly into the qualified product trough.
[0034] It should be noted that when the utility model is in use, the fermented biological bacteria raw material is sent to the upper surface of the sieve plate 5 through the material conveying device, and the crankshaft 14 is driven to rotate by the driving motor 17, so that the crankshaft 14 drives the curved neck 15 to move eccentrically, and the curved neck 15 drives the connecting rod 16 to move, so that the connecting rod 16 drives the sieve plate 5 to move back and forth along the dovetail chute 9. Through this device, the biological bacteria raw material can be screened quickly and continuously; at the same time, the first pulley 18 is driven to rotate by the crankshaft 14, so that the first pulley 18 drives the second pulley 18 through the belt 20. The second pulley 19 rotates, and the second pulley 19 drives the rotating shaft 10 to rotate, so that the rotating shaft 10 drives the turntable 11 to rotate, and the turntable 11 drives the pendulum 12 to move, and the pendulum 12 strikes the lower surface of the sieve plate 5 to vibrate the sieve plate 5. The vibration of the sieve plate 5 can disperse the biological bacteria on the surface of the sieve plate 5.
