Description

Technical Field

[0001] This utility model relates to the field of soybean flour fermentation technology, specifically to a sealed feeding device for soybean flour fermentation tanks. Background Technology

[0002] In the soybean flour fermentation process, raw soybean flour is usually packaged in woven bags. Traditionally, the soybean flour is transferred to a hopper by cutting or slicing open the woven bags, and then conveyed to the fermentation tank via a screw conveyor. In practice, it has been found that to completely empty the woven bags of residual material, operators often use high-frequency shaking and tapping to assist in unloading. This process leads to the following technical drawback: the fine soybean flour particles adhering to the woven bags form dust under vibration. Therefore, there is an urgent need for a sealed feeding device for soybean flour fermentation tanks with a sealing function. Utility Model Content

[0003] The main purpose of this utility model is to provide a sealed feeding device for soybean flour fermentation tanks, so as to solve the problem that in the existing technology, operators often use high-frequency shaking, slapping and other mechanical actions to assist in unloading, which causes the fine soybean flour particles attached to the woven bag to form dust under the action of vibration.

[0004] To achieve the above objectives, this utility model provides a sealed feeding device for a soybean flour fermentation tank, including a screw feeding mechanism, the feed inlet of which is connected to a hopper and the discharge outlet is vertically connected to a discharge pipe, the discharge pipe being inserted into the fermentation tank, and also including a machine housing.

[0005] A connecting hole is made on the bottom wall of the chassis and fixed on the flared end of the hopper. The connecting hole is located directly above the hopper.

[0006] The chassis has a door on one side, with two through holes, and a flexible isolation sleeve installed at each through hole;

[0007] Multiple support rods are fixedly arranged on the inner wall of the chassis, with the horizontally arranged support rods located directly above the connecting holes;

[0008] A scrubbing blade is set between two support rods, and the bottom ends of multiple scrubbing blades are fixed on a scraper. The scraper is located between multiple support rods on the bottom wall of the chassis and is connected to a drive mechanism for driving it to move axially along the support rods.

[0009] Preferably, the drive mechanism includes two first cylinders, the cylinder seats of the two first cylinders are fixedly connected to the outer wall of the casing, and the piston rods pass through the casing and are fixedly connected to both ends of the scraper.

[0010] Preferably, the sealed feeding device for the soybean flour fermentation tank also includes a pusher plate and two second cylinders, and the casing is a rectangular box.

[0011] The push plate is located inside the chassis, between the bottom wall of the chassis and multiple support rods;

[0012] The cylinder seats of the two second cylinders are fixedly connected to the side wall of the machine box, and the piston rods pass through the machine box and are fixedly connected to both ends of the push plate. The push plate and the scraper are symmetrically arranged on both sides of the connecting hole.

[0013] The scraper moves via the first cylinder, pushing the material at the corner of the casing into the connecting hole;

[0014] The push plate moves via the second cylinder, pushing the material at the corner of the chassis into the connecting hole.

[0015] Preferably, one side of the chassis has an inclined surface with an open portion. The switch door is located in the open portion, and the top wall of the switch door is hinged to the top wall of the chassis. A third cylinder is hinged to both sides of the middle portion, and the cylinder seat of the inclined third cylinder is hinged to the side wall of the chassis.

[0016] Preferably, the screw feeding mechanism includes a base frame, a cylindrical shell, and a motor;

[0017] An inclined cylindrical shell is fixedly connected to a base frame. An auger is rotatably installed inside the cylindrical shell. The shaft of the auger passes through the cylindrical shell and is fixedly fitted with a driven sprocket. The motor base is fixedly connected to the base frame, and the output shaft is fixedly fitted with a drive sprocket. A chain is fitted between the drive sprocket and the driven sprocket.

[0018] The first end of the cylindrical shell is connected to a lower tube, and the top end of the lower tube forms the feed port of the screw feeding mechanism;

[0019] The tail end of the cylindrical shell is connected to an upper tube, and the bottom end of the upper tube forms the discharge port of the screw feeding mechanism.

[0020] Preferably, the fermenter has a feed pipe at the top;

[0021] Both the discharge pipe and the upper pipe have circumferentially threaded sections on their outer walls. The two threaded sections are screwed together and fitted with an internally threaded pipe. A limiting ring is coaxially fitted on the outer wall of one end of the discharge pipe and inserted into the feed pipe. The gap between the feed pipe and the discharge pipe forms an annular space, and a flexible rope is coiled around the annular space.

[0022] Preferably, the flexible isolation sleeve is made of rubber.

[0023] The beneficial effects of the above scheme are:

[0024] The packaged soybean flour woven bags are laid flat on multiple support rods inside the machine casing, with the bottom of the bags facing the connecting holes on the bottom wall of the casing. The side door of the machine casing is closed to form a closed working space. The drive mechanism is started, which drives multiple slicing blades to move synchronously along the axis of the support rods, slicing open the bottom of the woven bags. The soybean flour falls into the hopper below through the connecting holes under the action of gravity. The operator inserts both hands into the flexible isolation sleeves on the switch door, grasps the woven bags through the flexible sleeves, and shakes and pats them to further empty the remaining soybean flour inside the bags. The flexible isolation sleeves isolate the air circulation between the inside and outside of the machine casing to prevent dust leakage. The small amount of dust generated by shaking is confined in the sealed machine casing and enters the hopper with the soybean flour through the connecting holes. After feeding is completed, the switch door is opened to take out the empty woven bags, and the switch door is closed to start the next cycle of operation. Compared to the traditional method of unloading by cutting open woven bags and then shaking and patting them in an open environment, this device forms a closed space with a chassis and a flexible isolation sleeve, which confines the fine soybean powder particles generated during the unloading process within the chassis, preventing the dust from spreading into the working environment. This not only improves the working environment for operators but also reduces the harm of dust to human health. Attached Figure Description

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Many specific details are set forth in the following description to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below. Example

[0032] like Figures 1-3 As shown, this embodiment provides a sealed feeding device for a soybean flour fermentation tank, including a screw feeding mechanism 1. The inlet of the screw feeding mechanism 1 is connected to a hopper 2, and the outlet of the screw feeding mechanism 1 is vertically connected to a discharge pipe 3. The discharge pipe 3 is inserted into the fermentation tank 4. The sealed feeding device for the soybean flour fermentation tank also includes a housing 5. A connecting hole 51 is opened on the bottom wall of the housing 5, and the housing 5 is fixed on the flared end of the hopper 2. The connecting hole 51 is located directly above the hopper 2, and the two are connected. Figure 2 As shown, one side of the chassis 5 has a switch door 52, and the switch door 52 has two through holes 53, as shown. Figure 3 As shown, a flexible isolation sleeve 54 is installed at each through hole 53. The flexible isolation sleeve 54 is made of rubber. One side of the chassis 5 has an inclined surface 50 with an opening 500. A switch door 52 is located in the opening 500. The top wall of the switch door 52 is hinged to the top wall of the chassis 5, and a third cylinder 501 is hinged to both sides of the middle of the switch door 52. The cylinder seat of the inclined third cylinder 501 is hinged to the side wall of the chassis 5. Multiple support rods 55 are fixedly arranged on the inner wall of the chassis 5. The horizontally arranged support rods 55 are located directly above the connecting hole 51. A scrubbing blade 56 is provided between every two support rods 55. The bottom ends of the multiple scrubbing blades 56 are fixed on a scraper 57. The scraper 57 is located between the bottom wall of the chassis 5 and the multiple support rods 55, and the scraper 57 is connected to a drive mechanism 58 for driving it to move axially along the support rods 55. The drive mechanism 58 includes two first cylinders. The cylinder seats of both first cylinders are fixedly connected to the outer wall of the housing 5, and the piston rods of the two first cylinders pass through the housing 5 and are fixedly connected to both ends of the scraper 57. The extension and retraction of the piston rods of the first cylinders can drive the scraper 57 to move axially along the support rod 55.

[0033] The packaged soybean flour woven bags are laid flat on multiple support rods 55 inside the machine housing 5, with the bottom of the woven bags facing the connecting hole 51 on the bottom wall of the machine housing 5. The switch door 52 on the side of the machine housing 5 is closed to form a closed working space. The drive mechanism 58 is started, and the drive mechanism 58 drives multiple slicing blades 56 to move synchronously along the axis of the support rods 55, slicing open the bottom surface of the woven bags. Under the action of gravity, the soybean flour falls into the hopper 2 below through the connecting hole 51. The operator inserts both hands into the flexible isolation sleeves 54 on the switch door 52, grasps the woven bags through the flexible sleeves, and shakes and pats them to further empty the soybean flour inside the bags. The flexible isolation sleeves 54 isolate the air circulation inside and outside the machine housing 5 to prevent dust leakage. The small amount of dust generated by shaking is confined in the sealed machine housing 5 and enters the hopper 2 along with the soybean flour through the connecting hole 51. After feeding is completed, the switch door 52 is opened to take out the empty woven bags, and the switch door 52 is closed to start the next cycle of operation. Compared to the traditional method of unloading by cutting open woven bags and then shaking and patting them in an open environment, this device forms a closed space with the casing 5 and the flexible isolation sleeve 54, which confines the fine soybean powder particles generated during the unloading process within the casing 5, preventing the dust from spreading into the working environment. This not only improves the working environment for operators but also reduces the harm of dust to human health.

[0034] The sealed feeding device for the soybean flour fermentation tank also includes a pusher plate 6 and two second cylinders 61. The housing 5 is a rectangular box. The pusher plate 6 is located inside the housing 5, between the bottom wall of the housing 5 and multiple support rods 55. The cylinder seats of the two second cylinders 61 are fixedly connected to the side walls of the housing 5, and the piston rods of the two second cylinders 61 are inserted into the housing 5 and fixedly connected to both ends of the pusher plate 6. The pusher plate 6 and the scraper 57 are symmetrically arranged on both sides of the connecting hole 51. The scraper 57 moves through the first cylinder, pushing the material at the corner of the housing 5 into the connecting hole 51. The pusher plate 6 moves through the second cylinders 61, pushing the material at the corner of the housing 5 into the connecting hole 51. Activating either the first or second cylinder 61 drives the pusher plate 6 or the scraper 57 to move along the bottom wall of the housing 5 from the side towards the connecting hole 51. During the movement of the pusher plate 6 or scraper plate 57, the soybean powder remaining at the corner of the machine box 5 is pushed towards the connecting hole 51, and falls into the hopper 2 below through the connecting hole 51 along the pushing force of the pusher plate 6 or scraper plate 57.

[0035] like Figure 2 , Figure 3As shown, the screw feeding mechanism 1 includes a base frame 10, a cylindrical shell 11, and a motor 12. The inclined cylindrical shell 11 is fixedly connected to the base frame 10. An auger 13 is rotatably mounted inside the cylindrical shell 11. The shaft of the auger 13 passes through the cylindrical shell 11 and is fixedly fitted with a driven sprocket 14. The motor 12's base is fixedly connected to the base frame 10, and its output shaft is fixedly fitted with a drive sprocket 15. A chain 16 is fitted between the drive sprocket 15 and the driven sprocket 14. A lower pipe 17 is connected to the first end of the cylindrical shell 11, and the top end of the lower pipe 17 forms the feed inlet of the screw feeding mechanism 1. An upper pipe 18 is connected to the tail end of the cylindrical shell 11, and the bottom end of the upper pipe 18 forms the discharge outlet of the screw feeding mechanism 1. This screw feeding mechanism 1 utilizes existing technology and will not be described in detail. The fermentation tank 4 has a feed pipe 41 at its top. Both the discharge pipe 3 and the upper pipe 18 have circumferentially threaded sections (not shown). Two threaded sections are screwed together to form an internally threaded pipe 19. A limiting ring 31 is coaxially fitted on the outer wall of one end of the discharge pipe 3 and inserted into the feed pipe 41. The gap between the feed pipe 41 and the discharge pipe 3 forms an annular space 100, and a flexible rope (not shown) is coiled around the annular space 100. The flexible rope seals the annular space 100, making the fermentation tank 4 more airtight. The working process of the screw feeding mechanism 1 is as follows: soybean powder falls from the hopper, the drive motor works, the motor drives the drive sprocket to rotate, the drive sprocket drives the driven sprocket to rotate through the chain, the driven sprocket drives the auger to rotate, and the rotating auger carries the soybean powder along the cylindrical shell 11 until it falls into the fermentation tank through the lower pipe.

[0036] Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
