[0015] The present invention is provided with a scraper rod. After the card column is separated from the abutment of the card slot, the other end of the exhaust pipe blows out exhaust gas toward the lower driving fan. The exhaust gas is used to blow the lower driving fan to rotate, the rotating rod follows the rotation of the lower driving fan, the sliding sleeve follows the rotation rod to rotate, and the four scraper rods follow the rotation of the sliding sleeve. The four scraper rods are used to scrape off impurities and small particles of feed on the top of the alkaline treatment liquid, so that the impurities and small particles of feed on the top of the alkaline treatment liquid flow into the storage space under the scraping of the scraper rod, and the alkaline treatment liquid carrying impurities and small particles of feed falls into the storage space, so that the exhaust gas after reacting with the alkaline treatment liquid can better enter the first exhaust pipe through the top of the alkaline treatment liquid, thereby preventing the impurities and small particles of feed on the top of the alkaline treatment liquid from seriously accumulating and the exhaust gas from being able to pass through the top of the alkaline treatment liquid well.

[0016] By setting a load-bearing ring, after the alkaline treatment liquid carrying impurities and small particle feed falls into the storage space, the alkaline treatment liquid is collected on the top of the load-bearing ring. As the weight borne by the load-bearing ring increases, multiple telescopic parts move downward and contract. The load-bearing ring moves downward, and after the drainage groove breaks away from the outer wall of the inner treatment shell, the alkaline treatment liquid directly above the load-bearing ring will enter the storage space below the load-bearing ring through the water receiving groove and the drainage groove. When the load-bearing ring moves downward, multiple connected columns follow the load-bearing ring to move downward, and the arc-shaped receiving bottom plate and the filling block follow the multiple connected columns to move downward, so that the large particle feed accumulated at the bottom of the inner treatment shell flows out from the bottom center of the inner treatment shell, which is used to discharge the large particle feed accumulated at the bottom of the inner treatment shell, and there is no need to frequently replace the alkaline treatment liquid.

[0017] By providing a bottom scraper, the bottom scraper can rotate with the rotating rod as the fan rotates, cleaning the bottom of the inner treatment shell and accelerating the flow of large feed particles from the bottom center of the inner treatment shell to prevent large feed particles from remaining attached to the bottom of the inner treatment shell. When the automatic feeding tank replenishes the alkaline treatment liquid, the bottom scraper and the rotating member can accelerate the mixing of the alkaline treatment liquid, thereby ensuring the same concentration throughout the alkaline treatment liquid, fully utilizing the alkaline treatment liquid and improving its utilization rate, eliminating the need for frequent replacement of the alkaline treatment liquid.

[0018] The present invention has an ingenious structure and does not require manual cleaning of impurities in the alkaline treatment liquid. When the alkaline treatment liquid reaches a certain height, the impurities attached to the alkaline treatment liquid can be discharged up and down, and the alkaline treatment liquid can be automatically replenished at the same time to maintain the neutralization reaction of the alkaline treatment liquid and quickly remove the acidic substances in the tail gas.

[0040] like Figures 1 to 2As shown, the vacuum assembly 30 includes a first vacuum pipe 31, an vacuum pump 32 and a second vacuum pipe 33, one end of the first vacuum pipe 31 is inserted into the top of the outer cover 55, one end of the vacuum pump 32 is fixedly connected to the other end of the first vacuum pipe 31, and one end of the second vacuum pipe 33 is fixedly connected to the other end of the vacuum pump 32, and the feeding assembly 60 includes a fixed rod 61, an automatic feeding tank 62 and a feeding pipe 63, one end of the fixed rod 61 is fixedly connected to the side wall of the outer processing shell 51, the automatic feeding tank 62 is fixedly connected to the other end of the fixed rod 61, the upper end of the feeding pipe 63 is inserted into the bottom of the automatic feeding tank 62, and the lower end of the feeding pipe 63 is sequentially passed through the outer processing shell 51 and the inner processing shell 53.

[0041] During installation: the outer treatment shell 51 is mounted on the top of the support assembly 40, the connector 52 is mounted on the inner sidewall of the outer treatment shell 51, the inner treatment shell 53 is mounted inside the outer treatment shell 51, the scraper assembly 70 is mounted inside the inner treatment shell 53, the receiving and discharging assembly 80 is mounted on the bottom of the storage space 56, the retaining member 71 is fixedly mounted on the middle sidewall of the inner treatment shell 53, and the load-bearing member 81 is mounted on the bottom of the storage space 56. The fermenter 12 is mounted on the top of the support member 11, the feeding valve 15 is mounted on the top of the fermenter 12, the four bottom scrapers 73 are fixedly mounted on the bottom sidewall of the rotating rod 720, the bottoms of the multiple telescopic members 811 are all mounted on the top of the fixed ring 810, the load-bearing ring 812 is slidably mounted in the storage space 56, and the filling block 822 is fixedly mounted on the top center of the arc-shaped receiving bottom plate 821.

[0042] During use: 1. The biological feed is fermented in the fermentation tank 12, and the exhaust gas produced by the fermentation enters the alkaline treatment liquid through the exhaust pipe 14. The large particles of feed carried in the exhaust gas will accumulate at the bottom of the inner treatment shell 53, and the small particles of feed carried in the exhaust gas will float on the top of the alkaline treatment liquid. The hydrogen sulfide contained in the exhaust gas will react with the alkaline treatment liquid to generate sodium sulfide and water, and the alkaline treatment liquid in the inner treatment shell 53 will rise. When the alkaline treatment liquid in the inner treatment shell 53 rises to the top of the inner treatment shell 53, the alkaline treatment liquid in the inner treatment shell 53 will push the floating block 744 to move upward, and the card column 745 will be separated from the abutment of the card slot 530. The other end of the exhaust pipe 14 is directed toward the top of the lower drive fan 722, used to blow the lower drive fan 722 to rotate, and the card column 745 is stuck in the card slot 530 to prevent the lower drive fan 722 from rotating. After the card column 745 is separated from the abutment of the card slot 530, the other end of the exhaust pipe 13 blows out the exhaust gas toward the lower driving fan 722, and the exhaust gas is used to blow the lower driving fan 722 to rotate, the rotating rod 720 follows the lower driving fan 722 to rotate, the sliding sleeve 740 follows the rotating rod 720 to rotate, and the four scraper rods 741 follow the sliding sleeve 740 to rotate. The four scraper rods 741 are used to scrape off impurities and small particles of feed on the top of the alkaline treatment liquid, so that the impurities and small particles of feed on the top of the alkaline treatment liquid flow into the storage space 56 under the scraping of the scraper rods 741. After the alkaline treatment liquid carrying impurities and small particles of feed falls into the storage space 56, the exhaust gas after reacting with the alkaline treatment liquid can better pass through the top of the alkaline treatment liquid into the first exhaust pipe 31, preventing the impurities and small particles of feed on the top of the alkaline treatment liquid from accumulating seriously and the exhaust gas from being able to pass through the top of the alkaline treatment liquid well.

[0043] 2. After the alkaline treatment liquid carrying impurities and small particles of feed falls into the storage space 56, the alkaline treatment liquid is collected on the top of the load-bearing ring 812. As the weight borne by the load-bearing ring 812 increases, the multiple telescopic parts 811 move downward and contract, the load-bearing ring 812 moves downward, and the drainage groove 814 disengages from the outer wall of the inner treatment shell 53. Then, the alkaline treatment liquid directly above the load-bearing ring 812 will enter the storage space 56 below the load-bearing ring 812 through the water receiving groove 813 and the drainage groove 814. When the load-bearing ring 812 moves downward, the multiple connected columns 820 move downward with the load-bearing ring 812, and the arc-shaped receiving bottom plate 821 and the filling block 822 move downward with the multiple connected columns 820, so that the large particles of feed accumulated at the bottom of the inner treatment shell 53 flow out from the bottom center of the inner treatment shell 53, which is used to discharge the large particles of feed accumulated at the bottom of the inner treatment shell 53.

[0044] 3. After the large-particle feed flows out from the bottom center of the inner processing shell 53, it falls to the arc-shaped receiving bottom plate 821, and then finally falls to the bottom of the outer processing shell 51 through the water outlet trough 823 and multiple drop troughs 824. At the same time, when the filling block 822 moves downward along with the multiple connected columns 820, the automatic feeding tank 62 will start, and the alkaline treatment liquid in the inner processing shell 53 will be supplemented with a higher-purity alkaline treatment liquid through the feeding pipe 63, thereby maintaining the concentration of the alkaline treatment liquid and preventing the concentration of the alkaline treatment liquid from decreasing, thereby failing to neutralize the acidic gases in the exhaust gas. When the weight of the liquid on the load-bearing ring 812 is unable to squeeze the multiple telescopic parts 811 to contract, the multiple telescopic parts 811 return upward, allowing the load-bearing ring 812 to return to its original position. After the large feed particles at the bottom of the inner treatment shell 53 flow out from the bottom center of the inner treatment shell 53, the level of the alkaline treatment liquid in the inner treatment shell 53 drops. The top scraper 74 moves downward under the action of gravity, and eventually the clamping column 745 enters the clamping groove 530, and the rotating rod 720 stops rotating. The waste alkaline treatment liquid at the bottom of the outer treatment shell 51 can be discharged by opening the drain pipe 54. Without the need to manually clean the top and bottom of the inner treatment shell 53 or manually replenish the alkaline treatment liquid, the concentration of the alkaline treatment liquid can be maintained, allowing the alkaline treatment liquid to effectively treat the acidic gases in the exhaust gas, eliminating the need for frequent replacement of the alkaline treatment liquid.

[0045] 4. As the rotating rod 720 rotates along with the lower drive fan 722, the bottom scraper 73 rotates along with the rotating rod 720, cleaning the bottom of the inner processing shell 53 and accelerating the flow of large feed particles from the bottom center of the inner processing shell 53, thereby preventing large feed particles from remaining attached to the bottom of the inner processing shell 53. When the automatic feeding tank 62 replenishes the alkaline treatment liquid, the bottom scraper 73 and the rotating member 72 accelerate the mixing of the alkaline treatment liquid, thereby ensuring that the concentration of the alkaline treatment liquid is uniform throughout the interior, fully utilizing the alkaline treatment liquid and improving its utilization rate, eliminating the need for frequent replacement of the alkaline treatment liquid.

[0046] The present invention is provided with a scraper rod 741. After the card column 745 is separated from the abutment of the card slot 530, the other end of the exhaust pipe 14 blows out exhaust gas toward the lower driving fan 722. The exhaust gas is used to blow the lower driving fan 722 to rotate, the rotating rod 720 follows the rotation of the lower driving fan 722, the sliding sleeve 740 follows the rotation of the rotating rod 720, and the four scraper rods 741 follow the rotation of the sliding sleeve 740. The four scraper rods 741 are used to scrape off impurities and small particles of feed on the top of the alkaline treatment liquid, so that the impurities and small particles of feed on the top of the alkaline treatment liquid flow into the storage space 56 under the scraping of the scraper rods 741, and the alkaline treatment liquid carrying impurities and small particles of feed falls into the storage space 56, so that the exhaust gas after reacting with the alkaline treatment liquid can better enter the first exhaust pipe 31 through the top of the alkaline treatment liquid, thereby preventing the impurities and small particles of feed on the top of the alkaline treatment liquid from seriously accumulating and the exhaust gas from not being able to pass through the top of the alkaline treatment liquid well.

[0047] By setting the load-bearing ring 812, after the alkaline treatment liquid carrying impurities and small particle feed falls into the storage space 56, the alkaline treatment liquid is collected on the top of the load-bearing ring 812. As the weight borne by the load-bearing ring 812 increases, the multiple telescopic parts 811 move downward and contract, the load-bearing ring 812 moves downward, and the drainage groove 814 disengages from the outer wall of the inner treatment shell 53, the alkaline treatment liquid directly above the load-bearing ring 812 will enter the storage space 56 located below the load-bearing ring 812 through the water receiving groove 813 and the drainage groove 814. When the load-bearing ring 812 moves downward, the multiple connected columns 820 move downward with the load-bearing ring 812, and the arc-shaped receiving bottom plate 821 and the filling block 822 move downward with the multiple connected columns 820, so that the large particle feed accumulated at the bottom of the inner treatment shell 53 flows out from the bottom center of the inner treatment shell 53, which is used to discharge the large particle feed accumulated at the bottom of the inner treatment shell 53.

[0048] By providing the bottom scraper 73, when the rotating rod 720 rotates along with the lower driving fan 722, the bottom scraper 73 can rotate along with the rotating rod 720, thereby cleaning the bottom of the inner processing shell 53 and accelerating the flow of large feed particles at the bottom of the inner processing shell 53 out of the bottom center of the inner processing shell 53, thereby preventing large feed particles from remaining attached to the bottom of the inner processing shell 53. When the automatic feeding tank 62 replenishes the alkaline treatment liquid, the bottom scraper 73 and the rotating member 72 can accelerate the mixing of the alkaline treatment liquid, thereby ensuring that the concentration of the alkaline treatment liquid is uniform throughout the interior, fully utilizing the alkaline treatment liquid, and thereby improving the utilization rate of the alkaline treatment liquid.

[0049] The present invention has an ingenious structure and does not require manual cleaning of impurities in the alkaline treatment liquid. When the alkaline treatment liquid reaches a certain height, the impurities attached to the alkaline treatment liquid can be discharged up and down, and the alkaline treatment liquid can be automatically replenished at the same time to maintain the neutralization reaction of the alkaline treatment liquid and quickly remove the acidic substances in the tail gas.

[0050] All possible combinations of the various technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0051] The above-described embodiments merely represent several embodiments of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
