Description

Technical Field

[0001] This utility model belongs to the field of fermentation equipment technology, and in particular relates to a fermentation tank for distiller's grains with a spiral guide plate structure. Background Technology

[0002] A fermentation tank for distiller's grains is a device used to treat organic waste such as distiller's grains, enabling the rational utilization of waste resources. The treatment of large accumulations of distiller's grains is a common problem faced by the brewing industry. Traditional treatment methods are costly, inefficient, and prone to causing environmental pollution. By treating distiller's grains in a fermentation tank, the resource utilization and fertilizer utilization of distiller's grains can be realized, reducing environmental pollution.

[0003] In simple terms, a fermentation tank consists of a tank body and a stirring system. The tank body is the main body of the fermentation tank, and the stirring system is installed inside the main body of the fermentation tank. After the lees and inoculum are put into the tank body, the stirring system, once started, will evenly mix the lees and inoculum to promote the fermentation process.

[0004] However, in actual operation, workers sequentially feed the lees and inoculum into the fermentation tank through pipes. This method can lead to uneven concentrations of lees or inoculum in certain areas, making it difficult to distribute them evenly and causing inconsistent fermentation, which affects the quality and yield of the final product. Therefore, a lees fermentation tank with a spiral baffle structure is needed to solve the above problems. Utility Model Content

[0012] In a further technical solution, the bottom wall of the tank has a rotating groove, the main body of the fermentation tank also includes a slag collection cylinder, the side wall of the rotating groove is set as an inclined surface, the cross-section of the slag collection cylinder is set as a frustum, the upper end diameter of the slag collection cylinder is larger than the lower end diameter, the side wall of the slag collection cylinder is in contact with the side wall of the rotating groove, and the lower end of the stirring rod is fixedly connected to the bottom wall of the slag collection cylinder.

[0013] A further technical solution is that a scraping ring is provided at the upper end of the slag collection cylinder, the outer wall of the scraping ring is in contact with the inner wall of the tank, and the upper end of the scraping ring is blade-shaped.

[0014] In a further technical solution, the tank body has a plurality of rotatable beads arranged in a circular pattern on the bottom wall forming the rotating groove, and the slag collecting cylinder has a plurality of spherical grooves arranged in a circular pattern on the bottom wall that is in contact with the rotating groove, with each of the beads rotatably disposed in each of the spherical grooves.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This invention features a feeding structure comprising a feeding cylinder, a connecting ring, and a guide plate. The guide plate is connected at both ends to the inner wall of the connecting ring and the side wall of the stirring rod, respectively. The guide plate is inclined, and the stirring rod is inserted into the feeding cylinder, which has a feeding chamber and a discharge port. Workers introduce lees or microbial inoculum into the tank through the feeding port, allowing the lees or inoculum to enter the feeding chamber.

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0026] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0027] like Figures 1 to 4 As shown, this utility model embodiment provides a fermentation tank for distiller's grains with a spiral guide plate structure, comprising:

[0028] Fermentation tank body 1, the fermentation tank body 1 includes tank body 11 and cover 12, the cover 12 is threaded to the upper end of tank body 11, and the cover 12 has a feed inlet 121;

[0029] The stirring structure 2 includes a spiral blade 21, a stirring rod 22, and a motor 23. The spiral blade 21 is fixedly mounted on the stirring rod 22. The output shaft of the motor 23 is connected to the stirring rod 22. The lower end of the stirring rod 22 is rotatably mounted on the bottom wall of the tank 11. The motor 23 is fixedly mounted on the bottom wall of the tank 11. The axis of the stirring rod 22 coincides with the center of the feed inlet 121.

[0030] The feeding structure 3 includes a feeding cylinder 31, a connecting ring 32, and a guide plate 33. The two ends of the guide plate 33 are respectively connected to the inner wall of the connecting ring 32 and the side wall of the stirring rod 22. Multiple guide plates 33 are provided, and the multiple guide plates 33 are distributed in a circle around the center of the connecting ring 32. The guide plates 33 are inclined. The outer wall of the connecting ring 32 is in contact with the inner wall of the tank 11. The stirring rod 22 is inserted into the feeding cylinder 31. The upper end of the stirring rod 22 is hollow. The inner wall of the feeding cylinder 31 has a feeding cavity 311. The feeding cylinder 31 has multiple spaced discharge holes 312 on the side wall of the feeding cavity 311. The feeding cavity 311 is connected to the stirring rod 22. The feeding cylinder 31 is placed at a predetermined distance above the connecting ring 32 and the guide plate 33.

[0031] In this embodiment, the worker introduces the lees or inoculum into the tank 11 through the inlet 121 on the cover 12, allowing the lees or inoculum to enter the feeding chamber 311 via the hollow stirring rod 22. Subsequently, the motor 23, after starting, drives the stirring rod 22 to rotate around its own axis. At this time, under the action of centrifugal force, the lees or inoculum in the feeding chamber 311 are thrown out of the feeding chamber 311 through the outlet 312 and fall onto the guide plate 33 under the action of gravity. The rotating guide plate 33 evenly disperses the lees or inoculum into the tank 11. The rotating spiral blades 21 mix the lees or inoculum in the tank 11 evenly. By setting the feeding cylinder 31 and the guide plate 33, the concentration of lees or inoculum in some areas of the tank 11 is avoided to be too high or too low, so that it is fully and evenly distributed inside the tank 11, ensuring consistent fermentation.

[0032] Specifically, a frustum 313 is provided on the bottom wall of the feed cylinder 31, the lower end of the frustum 313 is located below the discharge hole 312, and the upper end face of the frustum 313 is separated from the upper inner wall of the feed cylinder 31 by a predetermined distance.

[0033] In this embodiment, during the process of the lees or bacteria flowing into the feed chamber 311 via the stirring rod 22, the lees or bacteria flow from the upper end of the frustum 313 and through the inclined surface of the frustum 313 to the discharge hole 312; by setting the discharge hole 312, the lees or bacteria can flow out of the discharge hole 312 from the feed chamber 311 more quickly.

[0034] Specifically, the bottom wall of the tank 11 has a rotating groove 111, and the main body of the fermentation tank 1 also includes a slag collection cylinder 13. The side wall of the rotating groove 111 is set as an inclined surface, and the cross-section of the slag collection cylinder 13 is set as a frustum shape. The upper end diameter of the slag collection cylinder 13 is larger than the lower end diameter. The side wall of the slag collection cylinder 13 is attached to the side wall of the rotating groove 111, and the lower end of the stirring rod 22 is fixedly connected to the bottom wall of the slag collection cylinder 13.

[0035] Specifically, a scraping ring 131 is provided at the upper end of the slag collection cylinder 13. The outer wall of the scraping ring 131 is in contact with the inner wall of the tank body 11, and the upper end of the scraping ring 131 is blade-shaped.

[0036] In this embodiment, after fermentation is complete, the motor 23 stops running, and the liquid is transferred to the outside of the tank 11. The sediment produced after fermentation accumulates in the slag collection cylinder 13. The worker opens the cover 12 and pulls the stirring rod 22 upward, which in turn moves the slag collection cylinder 13 away from the rotating groove 111. At this time, the upper end of the scraping ring 131 scrapes the residue on the inner wall of the tank 11 into the slag collection cylinder 13. In this way, by setting up the slag collection cylinder 13, the process of cleaning the tank 11 is made simpler, so as to prevent the sediment inside the tank 11 from remaining for too long and affecting the next fermentation.

[0037] Specifically, the tank body 11 has a plurality of rotatable beads 112 arranged in a circular pattern on the bottom wall forming the rotating groove 111, and the slag collection cylinder 13 has a plurality of spherical grooves 132 arranged in a circular pattern on the bottom wall that is in contact with the rotating groove 111, and each bead 112 is rotatably disposed in each spherical groove 132.

[0038] In this embodiment, the rotating ball 112 on the bottom wall of the rotating groove 111 rotates in the ball groove 132 at the lower end of the slag collection cylinder 13. By setting the rotating ball 112, the friction between the rotating slag collection cylinder 13 and the bottom wall of the rotating groove 111 is reduced, thus extending the service life of the equipment.

[0039] Specifically, the main body 1 of the fermenter also includes a feed pipe 14, the lower end of which is fixedly installed on the cover 12, and the stirring rod 22 and the feed cylinder 31 are both connected to the feed pipe 14.

[0040] The working principle of this utility model is as follows:

[0041] First, the worker introduces the lees or bacteria into the tank 11 through the feed pipe 14, which is connected to the feed port 121 on the cover 12, so that the lees or bacteria enter the feed chamber 311 through the hollow stirring rod 22.

[0042] Subsequently, the motor 23, after starting, drives the stirring rod 22 to rotate around its own axis, thereby driving the spiral blade 21, the feed cylinder 31, the connecting ring 32, the guide plate 33 and the slag collection cylinder 13 to rotate synchronously around the stirring rod 22 axis.

[0043] At this time, under the action of centrifugal force, the lees or inoculum in the feeding chamber 311 are thrown out of the feeding chamber 311 through the discharge hole 312 and fall onto the guide plate 33 under the action of gravity; the rotating guide plate 33 evenly disperses the lees or inoculum into the tank 11; the rotating spiral blades 21 mix the lees or inoculum in the tank 11 evenly; in this way, by setting the feeding cylinder 31 and the guide plate 33, the concentration of lees or inoculum in some parts of the tank 11 is avoided to be too high or too low, so that it is fully and evenly distributed in the tank 11, ensuring consistent fermentation;

[0044] In addition, during the process of the lees or bacteria flowing into the feed chamber 311 via the stirring rod 22, the lees or bacteria flow from the upper end of the frustum 313 and through the inclined surface of the frustum 313 to the discharge hole 312; by setting the discharge hole 312, the lees or bacteria can flow out of the discharge hole 312 from the feed chamber 311 more quickly.

[0045] Meanwhile, the rotating beads 112 on the bottom wall of the rotating groove 111 rotate in the ball groove 132 at the lower end of the slag collection cylinder 13. By setting the rotating beads 112, the friction between the rotating slag collection cylinder 13 and the bottom wall of the rotating groove 111 is reduced, thus extending the service life of the equipment.

[0046] After fermentation is complete, motor 23 stops running, and the liquid is transferred to the outside of tank 11. The sediment produced after fermentation gathers in slag collection cylinder 13. The worker opens the cover 12 and pulls the stirring rod 22 upward, which in turn moves the slag collection cylinder 13 away from the rotating groove 111. At this time, the upper end of the scraping ring 131 scrapes the residue on the inner wall of tank 11 into the slag collection cylinder 13. In this way, by setting up the slag collection cylinder 13, the process of cleaning tank 11 is made simpler, and the sediment inside tank 11 is prevented from remaining for too long and affecting the next fermentation.

[0047] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
