[0019] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0020] Please see Figure 1 -5, a fermentation tank connected to a feeding system, comprising: Fermentation tank body 1; A feeding unit is fixedly installed on the top of the fermenter body 1, which is used to connect and feed materials into the interior of the fermenter body 1; A purification device is fixedly installed on one side of the fermenter body 1 to purify the gas inside the fermenter body 1; A stirring and turning unit is fixedly installed inside the fermentation tank body 1 to stir the materials inside the fermentation tank body 1; Control panel 2 is fixedly installed on the outer surface of the fermenter body 1; The feeding unit includes a fixed frame 3 fixedly installed on the top of the fermenter body 1, a feeding box 4 fixedly installed inside the fixed frame 3, a partition 5 fixedly installed inside the feeding box 4, a first feeding port 6 fixedly installed on the top of the feeding box 4, a second feeding port 7 fixedly installed on the top of the feeding box 4, a conveying pump 8 fixedly installed on the top of the fermenter body 1, a conveying pipe 9 fixedly installed at the input end of the conveying pump 8, a discharge pipe 10 fixedly installed at the output end of the conveying pump 8, a tee joint 11 fixedly installed at the bottom of the feeding box 4, a first normally closed valve 12 fixedly installed inside the tee joint 11, and a second normally closed valve 13 fixedly installed inside the tee joint 11.

[0021] The technical solution provided in this embodiment is as follows: When in use, different materials are first added into different compartments inside the feeding box 4 through the first feeding port 6 and the second feeding port 7. Then, when in use, the conveying pump 8 can be started to open the first normally closed valve 12 or the second normally closed valve 13, and the materials inside the different compartments can be extracted through the conveying pipe 9 and then sent into the interior of the fermentation tank body 1 through the discharge pipe 10. Then, the motor 19 is started to rotate the drive gear 23, which drives the external gear 22 to rotate the drive shaft 21, so that the scraper 24 scrapes off the material on the inner wall of the fermentation tank body 1. The feeding screw 25 is rotated to turn the material at the bottom of the fermentation tank body 1 to the top, so that the materials inside the fermentation tank body 1 are fully mixed, thereby making the fermentation faster. The gas produced by fermentation will enter the interior of the purification box 15 through the gas conveying pipe 16, and then the harmful impurities in the gas will be adsorbed by the purification filter element 31, and then discharged through the gas outlet pipe 17.

[0022] Furthermore, the purification unit includes a limiting member 14 fixedly installed on one side of the fermenter body 1, a purification box 15 fixedly installed inside the limiting member 14, an air supply pipe 16 fixedly installed on the top of the purification box 15, an air outlet pipe 17 fixedly installed on the bottom of the purification box 15, and a purification filter element 31 fixedly installed inside the purification box 15.

[0023] Specifically, by fixing the purification filter element 31 inside the purification box 15, the gas produced by the fermentation of the material inside the fermentation tank body 1 can be purified, preventing the gas after fermentation from being directly emitted into the air and polluting the environment.

[0024] Furthermore, the mixing and turning unit includes a housing 18 fixedly installed on the top of the fermentation tank body 1, a motor 19 fixedly installed inside the housing 18, a fixed bearing 20 fixedly installed inside the fermentation tank body 1, a drive shaft 21 fixedly installed inside the fixed bearing 20, an external gear 22 fixedly installed at the top of the drive shaft 21, a drive gear 23 fixedly installed at the output end of the motor 19, a scraper 24 fixedly installed outside the drive shaft 21, and a feeding screw 25 fixedly installed outside the drive shaft 21.

[0025] Specifically, by fixing the scraper 24 to the outside of the drive shaft 21, the material on the inner wall of the fermentation tank body 1 can be scraped off by the scraper 24, preventing the material from sticking to the inner wall and affecting the fermentation of the material.

[0026] Furthermore, a discharge port 26 is fixedly installed at the bottom of the fermentation tank body 1, and a solenoid valve 27 is fixedly installed inside the discharge port 26.

[0027] Specifically, by fixing a solenoid valve 27 inside the discharge port 26, the solenoid valve 27 can be opened after the material fermentation is completed, allowing the material to be discharged through the discharge port 26.

[0028] Furthermore, a support frame 28 is fixedly installed on the outside of the fermentation tank body 1, and anti-slip feet are fixedly installed on the bottom of the support frame 28.

[0029] Specifically, by fixing anti-slip feet to the bottom of the support frame 28, friction can be increased when using the fermenter, preventing the fermenter body 1 from shifting due to vibration.

[0030] Furthermore, one end of the conveying pipe 9 is fixedly connected to one end of the tee connector 11, and the partition 5 divides the interior of the feeding box 4 into two spaces, which are respectively connected to the first feeding port 6 and the second feeding port 7.

[0031] Specifically, the interior of the feeding box 4 is divided into two spaces by the partition 5, which allows two materials to be placed inside the feeding box 4 and prevents the two materials from mixing in advance. Different materials can be conveniently fed through the three-way connector 11, the first normally closed valve 12 and the second normally closed valve 13.

[0032] Furthermore, a feed inlet 29 is fixedly installed on the top of the fermenter body 1, and a sealing cover 30 is movably installed on the top of the feed inlet 29.

[0033] Specifically, by movably setting the sealing cap 30 on top of the feed inlet 29, external impurities can be prevented from entering the interior of the fermenter body 1 through the feed inlet 29, and gas inside the fermenter body 1 can also be prevented from leaking through the feed inlet 29.

[0034] Furthermore, the control panel 2 is internally fixedly connected with wires, and the control panel 2 is electrically connected to the delivery pump 8, motor 19, normally closed valve 12, normally closed valve 13 and solenoid valve 27 via the wires.

[0035] Specifically, by electrically connecting the control panel 2, the delivery pump 8, the motor 19, the first normally closed valve 12, the second normally closed valve 13, and the solenoid valve 27 together with wires, the control panel 2 can control the delivery pump 8 through the wires, thereby continuously adding the material inside the feeding box 4 into the fermentation tank body 1.
