Description

Technical Field

[0001] This application relates to the technical field of fermenters, and in particular to a fermenter. Background Art

[0002] A fermenter refers to a device used for microbial fermentation in industry. It is a microbial fermenter that improves fermentation efficiency by optimizing the fermentation conditions of microorganisms. Fermenters can be divided into aerobic and anaerobic types, depending on the aerobic and anaerobic types of the cultured microorganisms.

[0003] The utility model patent with the publication number CN219259989U proposes a new type of fermenter, which includes a tank frame. The inner side of the tank frame is fixedly installed with a tank body. The bottom of the tank body is fixedly connected with a collecting hopper. The top of the tank body is provided with a hinge, and a flap is fixedly connected to the outer surface of the hinge. The bottom of the collecting hopper is fixedly connected with a discharge pipe, and a valve is arranged on the discharge pipe. The top of the tank body is fixedly connected with a fixed platform, and a stirring shaft is rotatably connected to the inside of the tank body through a driving mechanism.

[0004] In the above-mentioned new type of fermenter, the spiral blade rotates through the driving mechanism. The spiral arc blade can not only stir the additive, but also bring the additive at a relatively lower position to a relatively higher position along with the spiral arc blade, achieving the effect of flipping the additive, preventing the problem that the existing fermenter has a single stirring method and poor effect, making it difficult to fully stir the additive, resulting in a reduction in the processing quality of the produced additive. This application provides another solution to solve this problem. Utility Model Content

[0005] The purpose of the present utility model is to solve or at least alleviate the problem that in an existing new type of fermenter, the spiral blade rotates through the driving mechanism. The spiral arc blade can not only stir the additive, but also bring the additive at a relatively lower position to a relatively higher position along with the spiral arc blade, achieving the effect of flipping the additive, preventing the problem that the existing fermenter has a single stirring method and poor effect, making it difficult to fully stir the additive, resulting in a reduction in the processing quality of the produced additive. This application provides another solution to solve this problem.

[0006] To achieve the above purpose, the present utility model adopts the following technical solutions:

[0007] A fermenter, comprising a tank body, wherein a stirring assembly for mixing additives and a shaking assembly for turning the tank body are provided on the tank body. The shaking assembly includes a first fixed seat arranged on one side of the tank body. The top end of the side wall of the first fixed seat far away from the tank body is fixedly connected with a stepping motor. The output end of the stepping motor is fixedly connected with a rotating shaft. The end of the rotating shaft far away from the stepping motor penetrates through the first fixed seat and is fixedly connected with a loop-shaped frame. The loop-shaped frame is sleeved on the tank body. A connecting assembly is provided between the tank body and the loop-shaped frame. The tank body is slidably connected with the loop-shaped frame through the connecting assembly.

[0008] By adopting the above technical solution, during use, the additives in the tank are stirred by the stirring assembly, and at the same time, the stepping motor is started to rotate forward and backward by 180 degrees, driving the loop-shaped frame to turn over, so that the tank body turns over. During the turning process of the tank body, the additives at the bottom of the tank body are located at the top and then fall freely, enabling the stirring assembly to stir the additives evenly, and avoiding as much as possible the problem that it is difficult to fully stir the additives, resulting in a reduction in the processing quality of the produced additives.

[0009] Optionally, the stirring assembly includes a driving motor fixedly connected to the top end of the tank body. The output end of the driving motor is fixedly connected with a stirring shaft. The end of the stirring shaft far away from the driving motor penetrates through the top end of the tank body and is located at the bottom end inside the tank body. A plurality of equally spaced stirring blades are fixedly connected to the side wall of the stirring shaft.

[0010] By adopting the above technical solution, by starting the driving motor to drive the stirring shaft to rotate, the stirring blades rotate in the tank body to stir the additives in the tank body and mix the additives.

[0011] Optionally, the connecting assembly includes sliders fixedly connected to both sides of the tank body. Vertical sliding grooves are formed on the side walls of the loop-shaped frame adjacent to the rotating shaft. The two sliders are respectively slidably arranged in the sliding grooves.

[0013] Optionally, vertical limiting rods are fixedly connected in the sliding grooves. The sliders are respectively sleeved on the limiting rods.

[0014] By adopting the above technical solution, the limiting rods can guide the sliding of the sliders to prevent the sliders from shaking when the tank body turns over, resulting in a collision between the tank body and the loop-shaped frame.

[0015] Optionally, a second fixing seat is provided on the side of the return frame away from the first fixing seat, and the second fixing seat is rotatably connected to a support rod at the top of a side wall of a side close to the return frame, and one end of the support rod away from the second fixing seat is fixedly connected to the return frame.

[0018] By adopting the above technical solution, through the buffer spring and the buffer block, when the tank body flips over and the slider slides downward in the slide groove, the slider contacts the buffer block, which will squeeze the buffer spring, reduce the impact of the slider sliding downward, and prevent the slider from colliding with the side wall of the slide groove.

[0019] Optionally, the distance between the bottom ends of the first fixing seat and the second fixing seat and the bottom end of the return frame is greater than the length of the slide slot.

[0020] By adopting the above technical solution, the slider is prevented from falling in the slide groove when the tank body is turned over, so that the tank body and the driving motor are in contact with the ground.

[0021] Optionally, a sealed bearing is provided at the connection between the stirring shaft and the tank body, the inner wall of the sealed bearing is fixedly connected to the stirring shaft, and the outer wall of the sealed bearing is fixedly connected to the tank body.

[0022] By adopting the above technical solution, the sealing performance of the tank body can be improved through the sealed bearing, thereby preventing the additive from seeping out from the gap at the connection between the stirring shaft and the tank body when the tank body is turned over.

[0023] In summary, the beneficial effects of this application are as follows:

[0024] 1. The present application adopts the coordinated arrangement between the stepping motor, the rotating shaft and the return frame. When in use, the additive in the tank is stirred by the stirring component, and the stepping motor is started to rotate forward and backward at an angle of 180 degrees, driving the return frame to flip, so that the tank is flipped. During the flipping process of the tank, the additive at the bottom of the tank is located at the top and then falls freely, so that the stirring component stirs the additive evenly, and the problem of difficulty in fully stirring the additive, which leads to reduced processing quality of the produced additive, is avoided as much as possible;

[0025] 2. Through the slider and the chute, the tank can be shaken up and down when it is turned over to improve the mixing effect of the additives. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0030] The following further elaborates on the present application in conjunction with the attached Figures 1 - 3 drawings.

[0031] Please refer to Figures 1 - 3 , a fermentation tank, comprising a tank body 1, a feed pipe and a discharge pipe are respectively fixedly connected to the top end and the bottom end of the tank body 1, sealing valves are installed on both the feed pipe and the discharge pipe, a stirring assembly for mixing additives and a shaking assembly for flipping the tank body 1 are provided on the tank body 1, the stirring assembly includes a driving motor 6, a stirring shaft 7 and stirring fan blades 8, the shaking assembly includes a first fixing seat 2 arranged on one side of the tank body 1, the first fixing seat 2 is fixedly connected to the ground to provide a supporting force, a stepping motor 3 capable of angular rotation is fixedly connected to the top end of the side wall of the first fixing seat 2 away from the tank body 1, a rotating shaft 4 for driving the tank body 1 to swing is fixedly connected to the output end of the stepping motor 3, one end of the rotating shaft 4 away from the stepping motor 3 penetrates through the first fixing seat 2 and is fixedly connected to a return frame 5 for connecting with the tank body 1, the return frame 5 is sleeved on the tank body 1, a connecting assembly is provided between the tank body 1 and the return frame 5, the connecting assembly includes a slider 9 and a chute 10, and the tank body 1 is slidably connected to the return frame 5 through the connecting assembly.

[0032] During use, the additives in the tank body 1 are stirred by the stirring assembly, and at the same time, the stepping motor 3 is started to rotate forward and backward by 180 degrees, driving the return frame 5 to flip, so that the tank body 1 is flipped. During the flipping process of the tank body 1, the additives at the bottom of the tank body 1 are located at the top and then freely fall, enabling the stirring assembly to uniformly stir the additives, and preferably avoiding the problem that it is difficult to fully stir the additives, resulting in a reduction in the processing quality of the produced additives.

[0033] Refer to Figure 2, the driving motor 6 is fixedly connected to the top end of the tank body 1. One end of the stirring shaft 7 is fixedly connected to the output end of the driving motor 6. The end of the stirring shaft 7 far from the driving motor 6 penetrates through the top end of the tank body 1 and is located at the bottom end inside the tank body 1. A plurality of stirring blades 8 are provided and fixedly connected to the side wall of the stirring shaft 7. By starting the driving motor 6 to drive the stirring shaft 7 to rotate, the stirring blades 8 rotate inside the tank body 1 to stir the additives in the tank body 1 and mix the additives.

[0034] Refer to Figure 1 , two sliders 9 are provided and fixedly connected to both sides of the tank body 1 respectively. The sliding grooves 10 are vertically arranged and opened on the side walls of the loop-shaped frame 5 adjacent to the rotating shaft 4. The two sliders 9 are respectively slidably arranged in the sliding grooves 10. Through the sliders 9 and the sliding grooves 10, when the tank body 1 is flipped, it can shake up and down to improve the mixing effect of the additives.

[0035] Refer to Figure 1 and Figure 3 , vertical limiting rods 11 are fixedly connected in the sliding grooves 10. The sliders 9 are respectively sleeved on the limiting rods 11. The limiting rods 11 can guide the sliding of the sliders 9 to prevent the sliders 9 from shaking when the tank body 1 is flipped, resulting in a collision between the tank body 1 and the loop-shaped frame 5.

[0036] Refer to Figure 2 , a second fixed seat 12 is provided on the side of the loop-shaped frame 5 far from the first fixed seat 2. The top end of the side wall of the second fixed seat 12 close to the loop-shaped frame 5 is rotatably connected to a support rod 13. The end of the support rod 13 far from the second fixed seat 12 is fixedly connected to the loop-shaped frame 5. Through the second fixed seat 12 and the support rod 13, the stability of the tank body 1 can be improved.

The buffer block 15 is sleeved on the limiting rod 11. Through the buffer springs 14 and the buffer blocks 15, when the tank body 1 is flipped and the slider 9 slides downward in the sliding groove 10, the slider 9 contacts the buffer block 15 and will squeeze the buffer spring 14, reducing the impact of the slider 9 sliding downward and preventing the slider 9 from hitting the side wall of the sliding groove 10.

[0038] Refer to Figure 2 , the distance between the bottom ends of the first fixed seat 2 and the second fixed seat 12 and the bottom end of the loop-shaped frame 5 is greater than the length of the sliding groove 10, preventing the slider 9 from descending in the sliding groove 10 when the tank body 1 is flipped, so that the tank body 1 and the driving motor 6 contact the ground.

[0039] Refer to Figure 2, a sealed bearing 16 is provided at the connection between the stirring shaft 7 and the tank body 1. The inner wall of the sealed bearing 16 is fixedly connected to the stirring shaft 7, and the outer wall of the sealed bearing 16 is fixedly connected to the tank body 1. Through the sealed bearing 16, the sealing performance of the tank body 1 can be improved, preventing additives from leaking out through the gap at the connection between the stirring shaft 7 and the tank body 1 when the tank body 1 is flipped.

[0040] The implementation principle of this application is as follows: During use, additives are put into the tank body 1 through the feed pipe, and then the driving motor 6 is started to make the stirring shaft 7 drive the stirring fan blades 8 to rotate in the tank body 1 to stir the additives in the tank body 1. At the same time, the stepping motor 3 is started to rotate forward and backward at an angle of 180 degrees, driving the return frame 5 to flip, so that the tank body 1 flips. During the flipping process of the tank body 1, the additives at the bottom of the tank body 1 are located at the top and then fall freely, enabling the stirring fan blades 8 to stir the additives evenly, and largely avoiding the problem that it is difficult to fully stir the additives, resulting in a reduction in the processing quality of the produced additives.
