Description

Technical Field

[0001] This utility model relates to the field of material conveying technology, and in particular to an anti-clogging screw conveyor for gluten powder. Background Technology

[0002] In brewing processes such as winemaking and vinegar making, koji powder is a key raw material for fermentation. A koji powder screw conveyor can accurately and efficiently transport koji powder to various production stages, such as mixing and fermentation tanks. Ensuring a stable supply of koji powder is crucial for guaranteeing the quality and quantity of brewed products.

[0003] During the production, storage, or transportation of koji powder, some lumps, fibers, or other foreign objects may be mixed in. When these foreign objects enter the screw conveyor, they can easily get stuck between the screw blades and the casing, hindering the normal transport of the koji powder and causing blockages. When the screw conveyor is blocked, it needs to be stopped for cleaning, which will interrupt the entire production process, increase production time and costs, and delay the production schedule.

[0004] Therefore, to address the problem of easy clogging during the existing koji powder transportation process, a clogging-proof koji powder screw conveyor is needed to solve the above problem. Utility Model Content

[0005] To address the problem of clogging during the transport of koji powder in existing technologies, this application provides a clogging-resistant koji powder screw conveyor. This conveyor utilizes multi-stage dynamic crushing and directional flow coordination to ensure smooth material output and prevent clogging during koji powder transport.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A clog-resistant screw conveyor for koji powder includes a transmission chamber. A mixing chamber is fixedly connected to and passes through the top left side of the transmission chamber. A second motor is fixedly connected to the top rear side of the mixing chamber. The drive end of the second motor is connected to an arc-shaped plate via a swing assembly. A connecting platform is rotatably connected to the outer wall of the arc-shaped plate. The bottom end of the connecting platform is fixedly connected to the top outer wall of the mixing chamber. A transmission rod and a transmission pipe are connected to the rear end of the connecting platform via a gear assembly. A screen is fixedly connected to the inner wall of the mixing chamber. A first motor is fixedly connected to the left end of the transmission chamber. The drive end of the first motor is connected to a threaded auger via a transmission assembly.

[0008] As a further improvement of this utility model, a feeding pipe is fixedly connected to the bottom right side of the transmission chamber, and an infeeding pipe is fixedly connected to the outer wall of the front end of the mixing chamber.

[0009] As a further improvement of this utility model, the swing assembly includes a crank rod fixedly connected to the second drive end of the motor, and the outer wall of the crank rod is sleeved on the inner wall of the arc-shaped plate.

[0010] As a further improvement of this utility model, the gear set includes a first bevel gear fixedly connected to the front end of the arc plate, and a second bevel gear fixedly connected to the top end of both the transmission rod and the transmission tube, wherein the first bevel gear and the second bevel gear are meshed together.

[0011] As a further improvement of this utility model, the outer wall of the transmission rod is sleeved on the inner wall of the second bevel gear, and the outer wall of the transmission pipe is rotatably connected to and passes through the top of the mixing chamber.

[0012] As a further improvement of this utility model, a second stirring frame is fixedly connected to the bottom end of the transmission rod, and a first stirring frame is fixedly connected to the bottom end of the transmission pipe.

[0013] As a further improvement of this utility model, several flipping plates are fixedly connected to one bottom end of both the transmission tube and the stirring frame, and the bottom end of the flipping plate is in close contact with the outer wall of the top end of the crank rod.

[0014] As a further improvement of this utility model, each of the left ends of the threaded auger is fixedly connected to a transmission gear, the transmission gears meshing with each other, and the right end of the front transmission gear is fixedly connected to a drive end of the motor.

[0015] In this invention, after the koji powder enters the mixing chamber through the feeding pipe, the second motor drives the crank to move the arc plate to reciprocate at the connecting platform. This oscillation causes the first bevel gear to rotate periodically in both directions, and the second bevel gear transmits the bidirectional torque to the transmission pipe and transmission rod respectively, driving the first and second mixing frames to generate an impact torque, breaking up the koji powder clumps. Combined with the screen, impurities are separated, and the sieved koji powder is then stably fed into the transmission chamber. This ensures the smooth output of materials and avoids blockages during the koji powder transmission process through the synergistic effect of multi-stage dynamic crushing and directional flow guidance.

[0029] Example 1: A clog-resistant screw conveyor for gluten powder includes a transmission chamber 1. A mixing chamber 2 is fixedly connected to and passes through the top left side of the transmission chamber 1. A motor 6 is fixedly connected to the top rear side of the mixing chamber 2. The drive end of the motor 6 is connected to an arc plate 9 via a swing assembly. A connecting platform 7 is rotatably connected to the outer wall of the arc plate 9. The bottom end of the connecting platform 7 is fixedly connected to the top outer wall of the mixing chamber 2. The rear end of the connecting platform 7 is connected to a transmission rod 12 and a transmission pipe 13 via a gear assembly. A screen 18 is fixedly connected to the inner wall of the mixing chamber 2. The screen has a gradient aperture structure on its surface and piezoelectric ceramic vibrating plates are installed on its edge for vibration screening. A motor 5 is fixedly connected to the left end of the transmission chamber 1. A threaded auger 19 is connected to the drive end of the motor 5 via a transmission assembly. The blades of the threaded auger 19 adopt a variable pitch design. The pitch at the feed end is 50-80mm, and the pitch at the discharge end is 120-150mm. A discharge pipe 4 is fixedly connected to the bottom right side of the transmission chamber 1. A feeding pipe 3 is fixedly connected to the outer wall of the front end of the mixing chamber 2.

[0030] Example 2: The oscillating assembly includes a crank rod 8 fixedly connected to the drive end of motor 2 6. The outer wall of the crank rod 8 is sleeved on the inner wall of the arc plate 9. A bevel gear 10 is fixedly connected to the front end of the arc plate 9. Bevel gears 2 11 are fixedly connected to the top ends of the transmission rod 12 and the transmission tube 13. The bevel gears 10 and 2 11 are meshed. The outer wall of the transmission rod 12 is sleeved on the inner wall of the bevel gear 2 11. The outer wall of the transmission tube 13 is rotatably connected to the top end of the mixing chamber 2 and passes through it. A stirring frame 2 15 is fixedly connected to the bottom end of the transmission rod 12. A stirring frame 14 is fixedly connected to the bottom end of the transmission tube 13. Several flipping plates 16 are fixedly connected to the bottom ends of the transmission tube 13 and the stirring frame 14. The bottom ends of the flipping plates 16 are in close contact with the outer wall of the top end of the crank rod 8. When the powder is put into the mixing chamber 2 through the feeding pipe 3, motor 2 6 is started to drive the crank rod 8 to perform planar circular motion. The rotational motion is converted by the crank-slider mechanism 201. The arc plate 9 reciprocates at the connecting platform 7, and the arc plate 9 drives the bevel gear 10 to rotate periodically in both directions with an oscillation angle of ±30°. The power is transmitted to the transmission pipe 13 and the transmission rod 12 through the bevel gear 10 and bevel gear 11, respectively. The transmission pipe 13 rotates clockwise at 200-300 rpm, and the transmission rod 12 rotates counterclockwise at 150-250 rpm, driving the stirring frame 14 and the stirring frame 2 15 to form a counter-current stirring. The stirring frame 14 is equipped with a corrugated flipping plate 16 with an inclination angle of 45°, and the stirring frame 2 15 is equipped with a serrated flipping plate 16 with an alternating distribution of 60°. During the dual-axis differential speed rotation, a dual action of shearing force and impact force is generated to break the powder agglomerates to a particle size ≤2mm. The screened material is evenly fed into the transmission chamber 1 through the spiral guide groove 203 built into the crank rod 8, while the impurities are discharged directionally by the high-frequency micro-amplitude vibration of the screen 18.

[0031] As one of the optimized structural designs for Example 1, such as Figures 2-4 As shown, each threaded auger 19 has a fixed transmission gear 17 at its left end, and the transmission gears 17 mesh with each other. The right end of the front transmission gear 17 is fixedly connected to the drive end of motor 5. The helical transmission gear 17 coaxially fixed to the left end of the threaded auger 19 is made of 40Cr alloy steel and is quenched and nitrided on the tooth surface. Adjacent transmission gears 17 form a bidirectional power transmission system with a herringbone tooth meshing method with an interlacing angle β = 15°. The right end of the front transmission gear 17 is rigidly connected to the permanent magnet synchronous drive end of motor 5 through an involute spline shaft, forming a reduction ratio torque amplification mechanism of i = 3.5:1, which enables the threaded auger to obtain a forward and reverse adjustable conveying mode. The gear meshing surface achieves dynamic clearance compensation through a circulating oil mist lubrication system, and is combined with a labyrinth seal ring to ensure stable power output of the transmission system in a dusty environment.

[0032] Working principle: When the koji powder is added into the mixing chamber 2 through the feeding pipe 3, the starting motor 6 drives the crank 8 to rotate, which in turn drives the arc plate 9 to oscillate back and forth at the connecting platform 7. This causes the arc plate 9 to drive the bevel gear 10 to rotate in both directions. The bevel gear 10, through the bevel gear 11, drives the transmission pipe 13 and the transmission rod 12 to rotate, which in turn drives the mixing frame 14 and the mixing frame 15 to rotate. This causes the mixing frame 14 and the mixing frame 15 to rotate by turning... The moving plate 16 agitates the koji powder intercepted at the crank rod 8. During the agitation of the moving plate 16, the clumps in the koji powder are broken up, and the impurities are screened out by the crank rod 8 and sieved into the transmission chamber 1. Then, when the motor 5 drives the transmission gears 17 on both sides, the screw conveyors 19 on both sides rotate in opposite directions, so that the screw conveyors 19 work together to transport the material. This ensures the smooth output of the material during the koji powder transmission process and avoids blockage during the koji powder transmission.
