Description

Technical Field

[0001] The invention relates to the technical field of fermented feed preparation devices, in particular to a fermentation disc. Background Art

[0002] The fermentation disc is a large disc composed of a sieve plate for supporting the koji material, and is widely used in the fermentation industry. The inside of the fermentation disc is supported by a central column, and the outside is supported by a tugboat or a steel frame. The upper part of the disc has a koji in and out auger for conveying the koji material and a koji turning auger for loosening the koji material.

[0003] At present, there are two types of fermentation discs on the market: rotating discs and non-rotating discs. The sieve plate of the rotating disc is fixed inside on the slewing support on the central column, and the outside of the sieve plate is supported by a tug. The disc rotates under the drive of the motor. The loosening auger and the outlet auger on the disc are fixed separately, and both need to be equipped with a lifting mechanism to move up and down under the action of their respective lifting mechanisms. This type of rotating disc needs to be equipped with internal and external lifts for the in and out auger and the loosening auger, which is expensive. The sieve plate of the non-rotating disc is directly fixed to the central column by the skeleton, and the outer end is fixed to the steel structure, and the sieve plate does not rotate. The inner end of the support beam of the loosening auger on the disc is fixed to the slewing support on the central column, and the outer end is supported on the outer circular track by a walking trolley. The support beam of the loosening auger is driven by the walking trolley to rotate around the central column. The feeding port and the discharge port are set on the side of the central column. The residual material is not easy to clean, and the residual material is easy to mold and even produce a bad smell, affecting the product quality.

[0004] It can be seen that the existing technology still needs to be improved and enhanced. Summary of the invention

[0028] The present invention provides a fermentation disc. To make the purpose, technical solution and effect of the present invention clearer and more specific, the present invention is further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0029] It is worth noting that the words "inside", "outside" and other words indicating directions in the present application are defined according to the installation direction, and "the inlet and outlet auger rotates inward" means that the inlet and outlet auger rotates in the direction of conveying materials to the inside of the disc body, and vice versa. It is only used to better describe the present invention and is not used to limit the present invention.

[0030] See also Figure 1-9 The present invention provides a fermentation disc, comprising: an in-and-out mechanism 1, a lifting mechanism 2, a loosening mechanism 3, a disc body 4, a central column 5 and a first driving mechanism (not shown in the figure); the in-and-out mechanism 1 is fixed on the loosening mechanism 3 through the lifting mechanism 2, and is eccentrically arranged relative to the disc body 4, the lifting mechanism 2 is used to control the lifting and lowering of the in-and-out mechanism 1, one end of the loosening mechanism 3 is fixed on the central column 5, and the other end is fixed through a supporting device (not shown in the figure) outside the disc body 4, the central column 5 passes through the center of the disc body 4 and is rotatably connected to the disc body 4, the inner wall 4b of the disc body 4 is connected to the central column 5, and the periphery is rotatably connected to the tugboat 6, and the first driving mechanism is rotatably connected to the central column 5, and is used to drive the disc body 4 to rotate. The in-and-out mechanism and the loosening mechanism of the fermentation disc are integrated, and only the lifting mechanism installed inside the disc body is required to control the lifting and lowering of the in-and-out mechanism, which has a simple structure and low cost. The disc body is fixed by the central column and the peripheral tugboat, and the operation is stable, saving installation space. In practical applications, the first driving mechanism drives the central column to rotate, thereby driving the disc body to rotate, so as to achieve material distribution in the disc body or to send the material to the in-and-out curved mechanism for discharge.

[0031] Specifically, the center column 5 includes a swivel support 51 and a plurality of columns 52, and connecting flanges 52a are provided at both ends of the columns 52. One end of two adjacent columns can be detachably connected, and the swivel support 51 is sleeved on the columns 52, and is rotatably connected to the columns 52 and the first driving mechanism respectively. In practical applications, the height of the center column can be connected to different numbers of columns according to actual needs, and installation and disassembly are convenient. The swivel support is used to transmit power between the first driving mechanism and the disc body. In one embodiment, a plurality of reinforcing ribs are also provided on the column, and the reinforcing ribs are provided at both ends of the column and connected to the connecting flanges, which can strengthen the strength of the column and eliminate radial deflection force.

[0032] See also Figure 1Furthermore, the bottom of the disc body 4 is composed of a plurality of sieve plates 4c, one end of the sieve plate 4c is fixed on the slewing support 51 of the central column 5, and the other end is connected to a tugboat 6 arranged on the periphery of the disc body 4. The tugboat supports the periphery of the disc body. Specifically, a driving gear 7 is provided between the tugboat and the disc body, and a guide shaft is connected to the bottom of the tugboat and the disc body, and the guide shaft is adapted to the driving gear.

[0033] See also Figure 1 and 2 Specifically, the lifting mechanism 2 includes a plurality of second driving mechanisms 21, connecting shafts 22 and lifting rails 23. The second driving mechanism 21 is fixed on the loosening mechanism 3, and a connecting shaft 22 is respectively connected to the two sides of the length direction of the in-and-out bending mechanism 1. The connecting shaft 22 is fixed on the loosening mechanism 3, and the other end of each connecting shaft 22 is respectively connected to a lifting rail 23. The lifting rail 23 is vertically fixed on the in-and-out bending mechanism 1 and is engaged with the loosening mechanism 3. The second driving mechanism in the lifting mechanism drives the connecting shafts on both sides to rotate synchronously. The connecting shafts can rotate synchronously in the forward or reverse direction, so that the connecting shafts can be lifted or lowered on the lifting rails, thereby driving the in-and-out bending mechanism to lift or lower. The two connecting shafts rotate synchronously, which can realize the overall synchronous lifting or lowering of the in-and-out bending mechanism, and has high stability. In one embodiment, the lifting mechanism includes a second driving mechanism, two connecting shafts and two lifting rails, and the second driving mechanism is a motor. Preferably, the installation height of the second driving mechanism is higher than the height of the koji inlet and outlet mechanism when it is working, so as to avoid direct contact between the koji material and the koji material and increase the difficulty of cleaning. The device has a simple structure, the koji inlet and outlet mechanism and the koji loosening mechanism are integrally connected to the fermentation disc, and no external fixing facilities are required, the cost is reasonable, the production space is saved, and it is easy to clean.

[0034] Furthermore, a gear is provided at one end of the connecting shaft connected to the lifting track, and the gear teeth of the gear are engaged with the lifting track and matched with the lifting track. The movement direction can be changed through the transmission of the gear, and the transmission is stable.

[0035] See also Fig. 9Specifically, the in-and-out curved mechanism 1 includes a frame 11, an in-and-out curved auger group 12, a third driving mechanism 13 and a transmission mechanism 14; the in-and-out curved auger group 12 is arranged in the frame 11, and includes a plurality of in-and-out curved auger 121 arranged side by side along the length direction of the frame 11, the two ends of the in-and-out curved auger 121 are respectively fixed on the frame 11, and two adjacent in-and-out curved auger 121 are connected end to end through a rotating shaft 122, and the third driving mechanism 13 is fixed on the upper surface of one end of the frame 11 close to the center column, and is connected to one end of the in-and-out curved auger group 12 through a transmission mechanism 14, and is used to drive the in-and-out curved auger group 12 to rotate inward or outward. When the in-and-out curved mechanism is installed and used, one end connected to the third driving mechanism is close to the inner wall of the disc body, and the other end is provided with a discharge port, which is located at the edge of the disc body, which is easy to discharge and clean the residual curved material, and the third driving mechanism is arranged on the inner side of the disc body, which can prevent the chain of the transmission mechanism from contacting the curved material. The in-and-out koji mechanism drives the transmission mechanism to operate through the third driving mechanism, thereby driving the in-and-out koji auger group to rotate inward to transmit the koji material, or to rotate outward to discharge the koji material through the transmission mechanism. The in-and-out koji auger group is connected by a rotating shaft, and each in-and-out koji auger rotates synchronously. Different numbers of in-and-out koji augers can be connected according to the size of the disc body. A shaft sleeve is sleeved on the rotating shaft between two adjacent in-and-out koji augers, and the shaft sleeve is rotatably connected to the rotating shaft to fix the in-and-out koji augers in the frame. Generally, the outer diameter of the in-and-out koji augers is smaller than the width and height of the frame, ensuring that the in-and-out koji augers are arranged inside the frame and will not affect other mechanisms in the disc body. The in-and-out koji auger group is connected to the frame by a screw rod, which is convenient for installation and disassembly. The third driving mechanism is arranged at the upper end of the frame and will not contact the koji material, so as to avoid the fermented koji material from being attached to the third driving mechanism, which is difficult to clean, and produces moldy or even foul smells, thereby avoiding the quality of the product being affected. Preferably, the third driving mechanism comprises a motor and a height-adjustable mounting frame, and the height-adjustable mounting frame is used for tensioning a sprocket of the transmission mechanism.

[0036] In one embodiment, the frame is a rectangular parallelepiped frame surrounded by square steel, and a plurality of reinforcing rods perpendicular to the length direction are connected to the upper part thereof along the length direction, and the two ends of the reinforcing rods are respectively fixed to the two long sides of the upper part of the rectangular parallelepiped frame. The setting of the frame is conducive to adding bent materials. As the disc body rotates, the in-and-out bent auger distributes the bent materials to various parts of the disc body through the gap of the frame, and it is easy to clean; when unloading, as the disc body rotates, the bent materials can smoothly enter the in-and-out bent auger and be transported out. The setting of the reinforcing rods improves the stability of the frame and is conducive to the fixation of the in-and-out bent auger.

[0037] Preferably, a baffle 15 is connected to the frame 11, and the baffle 15 is arranged on one side of the inlet and outlet koji auger group 12 along the length direction of the frame 11, and its edge is fixed on the frame 11 to prevent the koji material from passing through the frame 11. When adding koji material to the fermentation disc, as the koji material is added, a deep material area and a shallow material area will be formed on both sides of the baffle, and the baffle acts as a barrier to the koji material on both sides of the frame, so that the koji material can be evenly distributed through the rotation of the fermentation disc. If there is no baffle, the koji material can flow through both sides of the gap of the frame, and it is difficult to evenly distribute the koji material to various parts of the fermentation disc. In one embodiment, the cross-section of the baffle is a broken line, and the lower part is close to the inlet and outlet koji auger group to reduce the residue of koji material at the bottom of the auger.

[0038] See also Figure 6 and 7 Preferably, the in-and-out mechanism 1 also includes a hanging plate 16 and a bending plate 17. One side of the hanging plate 16 and the bending plate 17 overlap and are fixed by a screw. The other side of the hanging plate 16 overlaps the inner wall of the disc body and can move up and down with the in-and-out mechanism. The other side of the bending plate 17 is fixed on the bracket 11, and its upper and lower ends are respectively fixedly connected to the bracket 11. A through hole is provided on the bending plate, which is adapted to the transmission shaft of the transmission mechanism. The transmission shaft of the transmission mechanism passes through the bending plate to realize transmission. Preferably, a sealing ring is also provided on the through hole, so that the inner end of the frame forms a sealed structure, which can prevent the koji material from passing through the gap between the end of the frame and the inner wall of the fermentation disc, resulting in local accumulation of the koji material, which is difficult to be evenly distributed throughout the fermentation disc. The lower end of the bending plate is lower than the lower end of the in-and-out auger, and the upper end is not lower than the upper end of the in-and-out auger.

[0039] See also Figure 8 Specifically, the loosening mechanism 3 includes a support beam 31, a plurality of fourth driving mechanisms 32 and a loosening augers 33. The fourth driving mechanisms 33 are respectively fixed on the top of the support beam 31. Each fourth driving mechanism 33 is rotatably connected to a plurality of loosening augers 33 through an output shaft. The loosening augers 33 are vertically arranged below the support beam 31 and are arranged side by side and equidistantly along the length direction of the support beam 31. The fourth driving mechanism is fixed to the top of the support beam through a flange, which is convenient for installation and disassembly, can avoid direct contact with the koji material, and is easy to clean. By controlling a plurality of loosening augers respectively through a plurality of driving mechanisms, in actual applications, the koji material in the fermentation disc can be turned over in sections according to the fermentation status of the koji material, thereby saving resources. The loosening augers are equidistantly arranged and do not interfere with each other, thereby ensuring the loosening effect of the koji material in the fermentation disc.

[0040] Furthermore, the two ends of the support beam are respectively connected with fixing flanges 34, which are used to fix the two ends of the support beam to the central column of the fermentation disc and the supporting device outside the disc body, respectively, so that the support beam cannot move, avoid the risk of rollover caused by the mass eccentricity of the in-and-out curved mechanism, and reduce the requirements for the mechanical strength of the support beam. Preferably, the fixing flange is also provided with a plurality of reinforcing ribs to improve the strength of the flange and ensure the stability of the support beam.

[0041] See also Figure 4 Preferably, the upper part of the spiral shaft 331 of the loosening auger 3 is also connected to a plurality of stirring rods 332, the lower ends of the stirring rods 332 are located above the spiral blades 333 of the loosening auger, and the stirring rods 332 on two adjacent loosening auger 3 do not intersect each other. The stirring rod can further enhance the stirring effect of the loosening auger, and can effectively break up the agglomerated bent material. In one embodiment, the stirring rod is in an inverted "L" shape, with one end connected to the spiral shaft and the other end pointing vertically downward.

[0042] Specifically, an angle steel 35 is vertically fixed to the top of the support beam, and the angle steel is detachably connected to the second drive mechanism through a connecting rod and a nut, so that the second drive mechanism is fixed to the loose bending mechanism; a plurality of first fixing plates 36 and second fixing plates 37 are connected to a side surface of the support beam adjacent to the in-and-out bending mechanism, and the first fixing plates 36 are perpendicular to the side surface of the support beam, and are arranged in groups of two, and the upper end surface of the same group of first fixing plates is connected with a flange, which is used to fix the connecting shaft to the support beam. Generally, a bearing seat is connected to the connection between the connecting shaft and the first fixing plate, and the bearing seat is fixed by fixing the bearing seat to the first fixing plate. Usually, a group of first fixing plates is connected to each end of the connecting shaft. In one embodiment, the second fixing plates are arranged in groups of two, and each group is connected to a slide groove 38, and the back of the bottom of the slide groove is connected to one end of the second fixing plate, and its notch is clamped on the lifting guide rail, so that the lifting guide rail drives the lifting or lowering of the in-and-out bending mechanism by sliding up and down in the slide groove. It is worth noting that the longitudinal length of the lifting guide rail is longer than the length of the slide rail.

[0043] See also Figure 3 Specifically, it also includes a discharge port 41 and a sealing door 9. The discharge port 41 is arranged on the outer wall 4a of the disc body 4, and the sealing door 9 is used to seal the discharge port 41; the discharge port is arranged on the outer wall of the disc body, which is convenient for discharging and easy to clean up the residual materials. During the fermentation process, the sealing door is closed; when discharging, the sealing door is opened. Specifically, the sealing door is hinged to the outer wall of the disc body. The discharge port of the Qu in and out device is directly opposite to the discharge port of the fermentation disc. The material discharged from the Qu in and out device is discharged quickly, and the discharging speed is fast. Furthermore, the fermentation disc is also provided with a feeding mechanism 8 on the outside of the disc body.

[0044] When feeding the fermentation disc, the first driving mechanism is started to drive the disc body to rotate, and the second driving mechanism is started to drive the in-and-out koji mechanism to descend to the set height of the koji material. The in-and-out koji auger rotates inward under the drive of the third driving mechanism, and the koji material is fed from the outside of the disc through the feeding mechanism. The disc body rotates to bring the koji material into the in-and-out koji auger, and the in-and-out koji auger transports the material to the center of the disc body. As the disc body rotates, the koji material covers the entire disc body. Then the second driving mechanism rotates in the opposite direction, driving the in-and-out koji mechanism to lift and leave the surface of the koji material; the first driving mechanism, the second driving mechanism, and the third driving mechanism are closed.

[0045] When the bent material needs to be loosened, the fourth driving mechanism is started to drive the loosening auger to rotate to achieve the loosening of the bent material.

[0046] When discharging, start the first driving mechanism to drive the disc body to rotate, start the third driving mechanism to make the in-and-out curved auger rotate toward the outside of the disc body, and start the second driving mechanism to drive the in-and-out curved mechanism to descend to a set height. The disc body rotates to drive the curved material into the in-and-out curved auger, open the sealing door, and the in-and-out curved auger transports the curved material to the outside of the disc body. After the discharging is completed, reset the in-and-out curved mechanism, and then close the first driving mechanism, the second driving mechanism and the third driving mechanism respectively.
