Energy-saving and environment-friendly microbial fermentation system

Abstract

This invention relates to the field of microbial fermentation technology, specifically an energy-saving and environmentally friendly microbial fermentation system. The system comprises a shell mechanism, a stirring mechanism, an air inlet mechanism, an air outlet mechanism, and a cleaning mechanism. A hydraulic telescopic rod moves up and down to compress a squeezing rod. The downward movement of the squeezing rod drives a rotating body, which in turn drives a screw rod to thoroughly mix the sludge and aerobic thermophilic bacteria. During the downward movement of the hydraulic telescopic rod, the screw rod rotates, simultaneously moving a first rubber ball away from a first rubber ring. This allows air to enter the tank through the air inlet pipe, providing sufficient oxygen for the aerobic thermophilic bacteria. When the hydraulic telescopic rod moves upward, it moves a second rubber ball away from a second rubber ring. The heat generated by the reaction and the resulting air are then discharged through the air outlet pipe. Simultaneously, the reciprocating motion of the hydraulic telescopic rod drives the rotating body, which in turn drives a cleaning block to remove sludge adhering to the air outlet pipe, preventing blockage.

Description

Technical Field

[0001] This invention relates to the field of microbial fermentation technology, specifically to an energy-saving and environmentally friendly microbial fermentation system. Background Technology

[0002] Microbial fermentation refers to the process by which microorganisms, under suitable conditions, transform raw materials into products needed by humans through specific metabolic pathways. The production level of microbial fermentation mainly depends on the genetic characteristics of the microbial strain and the culture conditions.

[0003] When carrying out microbial fermentation of sludge, aerobic thermophilic bacteria need to be added and thoroughly mixed. The aerobic thermophilic bacteria decompose the organic matter in the sludge. The heat generated during the metabolism can raise the temperature of the pile layer, which can kill pathogens, parasite eggs, and viruses, and increase the fertility of the sludge. During the fermentation process, the oxygen content of the sludge pile gradually decreases from top to bottom. The lower layer of sludge is compacted, making it difficult for oxygen to enter, which is not conducive to the aerobic fermentation of sludge. Summary of the Invention

[0004] To address the problems in the existing technology, the present invention provides an energy-saving and environmentally friendly microbial fermentation system.

[0005] The technical solution adopted by this invention to solve its technical problem is: an energy-saving and environmentally friendly microbial fermentation system, including a shell mechanism, a stirring mechanism, an air inlet mechanism, an air outlet mechanism, and a cleaning mechanism. The shell mechanism contains a stirring mechanism, one end of which has an air inlet mechanism, one end of which has an air outlet mechanism, and one end of which has a cleaning mechanism. A hydraulic telescopic rod moves up and down to compress a squeezing rod. The downward movement of the squeezing rod drives a rotating body to rotate, which in turn drives a spiral rod to thoroughly stir the sludge and aerobic thermophilic bacteria. During the downward movement of the hydraulic telescopic rod, it drives the spiral rod to stir and simultaneously moves the first rubber ball away from the first rubber ring, allowing air to enter the tank through the air inlet pipe, providing sufficient oxygen for the aerobic thermophilic bacteria. During the upward movement of the hydraulic telescopic rod, it moves the second rubber ball away from the second rubber ring, allowing the heat and air generated by the reaction to be discharged through the air outlet pipe. Simultaneously, the reciprocating up and down movement of the hydraulic telescopic rod drives the rotating body to rotate, which in turn drives a cleaning block to clean the sludge adhering to the air outlet pipe, preventing blockage.

When the hydraulic telescopic rod moves downward, it will drive the extrusion rod to move downward. The extrusion rod moves downward, and the connecting block moves downward. The downward movement of the connecting block will compress the first spring. The downward movement of the extrusion rod will drive the first connecting rod to move downward. The downward movement of the first connecting rod will drive the rotating pin to move downward. The downward movement of the rotating pin will drive the rotating body to rotate. The rotation of the rotating body will drive the transmission shaft to rotate. The upper end of the telescopic rod is inclined, so that when the rotating pin extrudes downward, the rotating body can only rotate to one side. The rotation of the transmission shaft will drive the screw rod to rotate. The rotation of the screw rod will cause the bottom sludge to turn over to the top and be fully mixed with the aerobic thermophilic bacteria.

[0008] Specifically, the air intake mechanism includes a first steel wire rope, one end of which is fixedly connected to a pressing rod. The first steel wire rope is tightly fitted to the side wall of a first movable pin, and the side wall of the first steel wire rope is tightly fitted to a second movable pin.

When the rotating body rotates, it drives the guide groove to rotate, which in turn drives the second torsion pin to reciprocate up and down. A wire mesh is installed at one end of the air outlet pipe to prevent large pieces of sludge from clogging the air outlet pipe during stirring. The reciprocating motion of the torsion pin drives the second connecting rod to reciprocate up and down, which in turn drives the movable block to reciprocate up and down, which in turn drives the third connecting rod to reciprocate up and down, which in turn drives the cleaning block to reciprocate up and down. In this way, the cleaning block can clean the sludge attached to the wire mesh.

[0011] The beneficial effects of this invention are:

[0012] (1) The energy-saving and environmentally friendly microbial fermentation system of the present invention uses a hydraulic telescopic rod to press the extrusion rod by moving up and down.

[0032] In use, sludge and aerobic thermophilic bacteria are first poured into tank 12 through inlet 11. The hydraulic telescopic rod 21 moves up and down periodically. As the hydraulic telescopic rod 21 moves downward, it drives the extrusion rod 22 downward. The downward movement of the extrusion rod 22 causes the connecting block 24 to move downward, compressing the first spring 25. The downward movement of the extrusion rod 22 then drives the first connecting rod 27 downward, which in turn drives the rotating pin 28 downward. The downward movement of the rotating pin 28 then drives the rotation... The rotating body 29 rotates, which drives the transmission shaft 211 to rotate. The upper end of the telescopic rod 214 is inclined, so when the rotating pin 28 presses downwards, the rotating body 29 can only rotate to one side. The rotation of the transmission shaft 211 drives the screw rod 213 to rotate, which in turn causes the bottom sludge to be turned upside down and thoroughly mixed with the aerobic thermophilic bacteria. As the extrusion rod 22 moves downwards, it pulls the first steel wire rope 31.

When the hydraulic telescopic rod 21 moves upward, the protrusion drives the slider 41 upward. The upward movement of the slider 41 drives the second steel wire rope 42 upward. The upward movement of the second steel wire rope 42 pulls the second rubber ball 45 away from the second rubber ring 48. Thus, the heat and air generated during the reaction are discharged through the outlet pipe 17. When the rotating body 29 rotates, it drives the guide groove 210 to rotate. The rotation of the guide groove 210 drives the second torsion pin 51. The device moves up and down repeatedly. A wire mesh 57 is installed at one end of the vent pipe 17 to prevent large pieces of sludge from clogging the vent pipe 17 during mixing.

The up-and-down reciprocating motion of the second connecting rod 52 drives the moving block 53 to move up and down repeatedly. The up-and-down reciprocating motion of the moving block 53 drives the third connecting rod 55 to move up and down repeatedly. The up-and-down reciprocating motion of the third connecting rod 55 drives the cleaning block 56 to move up and down repeatedly. In this way, the cleaning block can clean the sludge attached to the wire mesh 57.
