Abstract
Description
Technical Field
[0001] This utility model belongs to the field of food processing technology, and specifically relates to a sieving device for processing soybean flour. Background Technology
[0002] Currently, Chinese utility model patent CN222709746U discloses a soybean crushing and screening device. This screening device has the following defects during use: When screening soybean flour, the inner wall of the screen cylinder becomes clogged with clumps due to long-term screening, resulting in a decrease in screening efficiency. Impurities mix and accumulate with qualified soybean flour, leading to incomplete screening. It may also introduce secondary pollution due to improper operation, resulting in unstable overall screening quality. At the same time, clumps of soybean flour enter the screen directly without being fully dispersed, causing frequent clogging of the screen holes, requiring manual shutdown for cleaning. Fine powder is easily left in coarse particles due to uneven dispersion, reducing screening accuracy and easily causing material adhesion or discontinuous screening.
[0003] To address the problems mentioned in the background above, a sieving device for soybean flour processing is proposed. Utility Model Content
[0004] The purpose of this invention is to provide a sieving device for soybean flour processing, which has the advantages of preventing clogging and preventing agglomeration.
[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a sieving device for soybean flour processing, comprising a sieve box, wherein a rotating rod 1 is rotatably connected through and rotatably to the top left side of the sieve box away from the center, and the right side of the rotating rod 1 is rotatably connected through and rotatably to the top right side of the sieve box away from the center; a rotating rod 2 is rotatably connected through and rotatably to the top left side of the sieve box near the center, and the right side of the rotating rod 2 is rotatably connected to the middle right side of the inner wall of the sieve box; a brush is sleeved in the middle of the surface of the rotating rod 1; a connecting rod is bolted to the top and bottom right side of the rotating rod 2; a sieve cylinder is bolted to the end of the connecting rod away from the rotating rod 2; a motor 1 is fixedly sleeved on the right side of the rotating rod 1; a feeding mechanism is provided at the top right side of the sieve box near the center; and a transmission mechanism is provided on the left side of the rotating rod 1.
[0006] The above technical solution involves placing a storage box at the bottom of the discharge port and a waste bin at the bottom of the waste port. Soybean powder is fed into the inlet, undergoes initial screening through the feeding box, and then enters the screen cylinder through the opening. Motor 1 drives rotating rod 1, which in turn drives gear 1 and a brush. Gear 1 drives gear 2, which in turn drives rotating rod 2, which in turn drives a connecting rod. The connecting rod then drives the screen cylinder to rotate. This rotation of the screen cylinder screens the soybean powder inside. Good, fine soybean powder is sieved out from the bottom of the screen and falls into the storage box from the discharge port. Impurities are sieved out from the waste port on the left due to the centrifugal force of the rotating screen cylinder. The rotating brush cleans the screen holes on the surface of the screen cylinder to prevent clogging. The rotating screen cylinder achieves efficient secondary screening. Under centrifugal force, qualified fine soybean powder is accurately sieved out from the bottom, while impurities are thrown towards the waste port on the left for automatic separation. The top brush continuously cleans the inner wall of the screen cylinder, effectively preventing clogging, ensuring continuous production, balancing screening accuracy and stability, and significantly reducing the frequency of manual cleaning.
[0007] The present invention is further configured such that the feeding mechanism includes a feeding box, which is bolted to the top of the right side of the sieve box near the middle, and the left side of the top of the feeding box is bolted to the bottom of motor one. Motor two is embedded in the bottom of the feeding box, and a rotating rod three is fixedly sleeved on the top of motor two. The bottom and top of the rotating rod three are rotatably connected to the center of the bottom and the left side of the top of the feeding box. Stirring blade one is bolted to the two sides of the rotating rod three away from the top of the middle, and stirring blade two is bolted to the two sides of the rotating rod three near the bottom of the middle. A sieve is bolted to the middle of the inner wall of the feeding box, and the top of the rotating rod three near the middle penetrates the center of the top and bottom of the sieve and is rotatably connected. An opening is provided on the bottom of the right side of the sieve box near the middle.
[0008] The above technical solution employs a feeding mechanism. The soybean powder to be screened is fed into the feeding box through the inlet. The powder falls onto the screen, and motor two drives rotor three to rotate. Rotor three then drives stirring blades one and two to rotate. Stirring blade one breaks up the clumps of soybean powder on the screen, and the broken powder is sieved out from the bottom of the screen and falls to the bottom of the feeding box. Stirring blade two further disperses the powder and, through centrifugal force, throws it into the opening, entering the screen cylinder for secondary screening. The synergistic effect of two-stage mechanical stirring and centrifugal screening significantly improves the soybean powder processing efficiency. Stirring blade one at the feeding end quickly breaks up clumps, ensuring initial uniform dispersion. After pre-screening, stirring blade two further disperses the powder, and centrifugal force allows fine powder to efficiently penetrate the screen cylinder, reducing the risk of clogging, ensuring screening continuity, and avoiding complex maintenance requirements.
[0009] The present invention is further configured such that the transmission mechanism includes a first gear, the first gear is fixedly sleeved on the left side of the first rotating rod, the second gear is fixedly sleeved on the left side of the second rotating rod, and the bottom of the first gear and the top of the second gear mesh.
[0010] The above technical solution is adopted: by setting up a transmission mechanism, the motor drives the rotating rod to rotate, the rotating rod drives the gear to rotate, the gear drives the gear to rotate, the gear drives the rotating rod to rotate, the rotating rod drives the connecting rod to rotate, and the connecting rod drives the screen cylinder to rotate.
[0011] The present invention is further configured such that a feed inlet is provided through and sleeved on the right side of the top of the feed box, and a discharge outlet is provided at the bottom of the sieve box.
[0012] The above technical solution, by setting up an inlet and an outlet, facilitates material feeding and discharging.
[0013] The present invention is further configured such that a waste outlet is provided through and fitted onto the bottom left side of the sieve box near the middle.
[0014] The above technical solution allows for the discharge of waste and impurities by setting up a waste outlet.
[0015] The present invention is further provided that a base is bolted to the bottom of both sides of the sieve box away from the middle.
[0016] The above technical solution uses a base to stabilize the device.
[0017] The present invention is further configured such that the front of the sieve box and the right side of the feed box are rotatably connected by a hinge.
[0018] The above technical solution allows for easy opening and maintenance of the screen box and feed box by incorporating a door.
[0019] In summary, this utility model has the following beneficial effects:
[0020] 1. This utility model achieves efficient secondary screening through a rotating screen cylinder. Under the action of centrifugal force, qualified fine powder of soybean flour is accurately screened out from the bottom, while impurities are thrown to the waste port on the left side for automatic separation. The top brush continuously cleans the inner wall of the screen cylinder, effectively preventing blockage, ensuring continuous production, taking into account both screening accuracy and stability, and significantly reducing the frequency of manual cleaning.
[0021] 2. This utility model significantly improves the processing efficiency of soybean flour through the synergistic effect of two-stage mechanical stirring and centrifugal sieving. The first stirring blade at the feed end quickly breaks up the clumps, ensuring uniform initial dispersion. After pre-screening by the screen, the second stirring blade further disperses the powder, and the centrifugal force allows the fine powder to penetrate the screen cylinder efficiently, reducing the risk of clogging, ensuring the continuity of sieving, and avoiding complex maintenance requirements.
