Description
Technical Field
[0001] This utility model belongs to the technical field of starch screening devices, and specifically relates to a screening device for starch processing. Background Technology
[0002] Currently, starch screening devices are mainly used for starch grading, impurity removal, and purification to ensure starch particle size uniformity and quality.
[0003] The most common starch screening device is the vibrating screening device. The vibrating screening device mainly consists of a screen box, a vibrating motor, a damping spring, a feed inlet and a discharge outlet. The screening device uses a combination of a vibrating motor and a vibrating spring. The vibrating motor provides a high-frequency vibration source, which drives the screen box to move. The damping spring is used to support the screen box and reduce the vibration transmitted to the frame, which helps the screen box to form a vibrating structure. The vibrating motor (or eccentric block) generates high-frequency, low-amplitude mechanical vibration, which drives the screen box to perform three-dimensional motion (horizontal, vertical, and inclined composite vibration), causing starch granules to be thrown, tumbled, and diffused on the screen, thus forming the processing form of starch screening.
[0004] However, starch is screened by vibration, which uses mechanical vibration to screen starch particles by size. Starch is relatively easy to absorb moisture or the influence of environmental humidity, which causes starch to clump together. However, with the above-mentioned vibration screening device, the starch clumps need to be processed repeatedly to break up the clumps, which reduces processing efficiency.
[0005] This application provides a screening device for dispersing agglomerated starch. Utility Model Content

The inner layer is located inside the outer layer and is rotatable. The screen block is located inside the inner layer. The screen block is also rotatable due to the rotation of the inner layer. The rotation of the screen block can disperse (break up) clumps of starch, thus improving the processing efficiency of starch screening. The screening device of this application solves the problems mentioned in the background art of the prior art.
[0007] The technical solution of this utility model is implemented as follows: The screening device includes: A base, one end of which is fixed to one side of a base plate, and the base is rectangular in shape; The outer layer, one side of which is inserted into the interior of the base; A fixing block is provided on one side of the outer surface, and there are multiple fixing blocks, with fixing blocks provided at both the top and bottom of the outer layer; A limiting layer is provided on the other side of the outer layer; The outer layer is connected to the base frame by a fixing block located at the lower position; The outer layer is connected to the fixing block provided in the upper position and the fixing block provided in the limiting layer; The outer layer has a discharge block at its lower end, and a discharge port is provided on one side of the discharge block; Preferably, the discharge block is conical in shape; Preferably, the fixing block provided on the outer layer is connected to the fixing block provided on the limiting layer by bolts, and the bolts form a positioning connection; Inner layer, which is inserted inside the outer layer; A protruding pulley is provided on one side of the inner layer surface, and the pulley is positioned between the outer layer and the limiting layer.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] Example 1: like Figures 1-2 As shown: The screening device includes a base, an outer layer 3, an inner layer 4, and a screen block. The outer layer 3 is located on a base 20 on one side of the base. The inner layer 4 is inserted inside the outer layer 3. A pulley 40 is located on one side of the inner layer 4, and the pulley 40 is connected to a transmission belt 5. The transmission belt 5 is connected to a main shaft of a driving device. The inner layer 4 can rotate. The inner layer 4 is driven by the transmission belt 5 and the driving device 50, which facilitates the rotation of the inner layer 4 and the screen block located in the inner layer 4. When starch is screened in the inner layer 4, the rotation of the inner layer 4 drives the screen blades 8 of the screen block to rotate, thus dispersing (breaking up) the clumps of starch, saving the repeated screening of clumps of starch, and improving the processing efficiency of starch screening. like Figures 2-4 As shown: The screen block includes a first block, a second block and a third block 73, and a second layer is located between the first block and the third block 73. The second layer may have multiple layers. like Figure 5 As shown: The top of the first piece is provided with a positioning ring 7, the middle of the positioning ring 7 is provided with a cross rod 70, and a protruding positioning rod 71 is provided at the intersection on one side of the cross rod 70; like Figure 6 As shown: The second piece is equipped with a screen plate 72 on the top. One side of the screen plate 72 is equipped with a protruding screw 720, and the other side is equipped with a protruding positioning rod 71. like Figure 4 As shown: The third piece 73 has a protruding screw 720 on one side; The positioning rod 71 has a keyway 710 on one side and a locking hole 711 at one end. The positioning rod on the cross rod 70 and the positioning rod 71 on the screen plate 72 have the same structure. The screw 720 of the screen plate 72 and the third block 73 passes through the locking hole 711 of the positioning rod 71. However, the combination of the first block, the second block and the third block 73 forms an integral structure. like Figure 7 As shown: A key block 80 is provided on one side of the screen blade 8. The key block 80 passes through the key groove 710 provided on the positioning rod 71. The key block 80 and the key groove 710 are connected. When installing the key block 80, it is only necessary to align it with the key groove 710 and insert it, which facilitates the installation and disassembly of the screen blade 8. The inner layer 4 is inserted inside the outer layer 3. A support ring 42 is provided on one side of the inner layer 4. The positioning ring 7 is placed on the side of the support ring 42 provided in the inner layer 4. The screen block forms a positioning and installation structure by connecting the positioning ring 7 and the support ring 42. One side of the inner layer 4 is provided with a protruding pulley 40, and a transmission belt 5 is provided inside the pulley 40. One side of the transmission belt 5 is connected to the main shaft of the drive device 50 (motor, cylinder). The inner layer 4 achieves rotation through the transmission of the transmission belt 5. Preferably, the connection between the pulley 40, the main shaft, and the transmission belt 5 is a toothed connection structure, which uses tooth meshing to improve the stability of the transmission belt 5 during transmission. The outer layer 3 has a limiting layer 31 on the other side, and one end of the inner layer 4 passes through the limiting layer 31. The outer layer 3 and the limiting layer 31 are independent entities, but there is a gap between the outer layer 3 and the limiting layer 31 to facilitate the placement of the pulley 40 between the outer layer 3 and the limiting layer 31. The inner layer 4 forms a positioning and installation structure, and through the installation of the outer layer 3 and the limiting layer 31, the inner layer 4 has a structure that is easy to disassemble and install. Preferably, the outer layer 3, the inner layer 4, and the screen block are all circular in shape; however, the inner layer 4 penetrates the interior of the outer layer 3, which helps the inner layer 4 to rotate. The outer layer 3 has multiple fixing blocks 30 on its surface. The fixing blocks 30 are arranged in an upper and lower position. The upper fixing block 30 of the outer layer 3 is connected to the fixing block 30 of the limiting layer 31. The fixing blocks 30 of the outer layer 3 are connected to the fixing blocks 30 of the limiting layer 31 by bolts, and the bolts form a positioning connection. However, the bolts are assembled with the outer layer 3 and the limiting layer 31 by positioning pins, which helps to achieve a structure in which a gap is formed between the outer layer 3 and the limiting layer 31. One end of the base 20 is fixed to one side of the base plate 2. The base 20 is rectangular in shape, and one side of the outer layer 3 passes through the interior of the base 20. The outer layer 3 is connected to the frame of the base 20 by a fixing block 30 provided at the lower position. The connection is made by bolts, which helps to form a fixed structure between the outer layer 3 and the base 20, and facilitates the disassembly and installation of the outer layer 3 and the base 20. like Figure 1 As shown: the drive device 50 is fixed on one side of the support 51, and one end of the support 51 is fixed on one side of the base plate 2, which helps the drive device 50 and the transmission belt 5 connected to the inner layer 4 to form a horizontal shape, thereby improving the stability of the transmission belt 5 in transmitting power.
[0020] Example 2: The inner layer 4 has a protruding locking ring 41 at one end, which protrudes from one end of the limiting layer 31 and is connected to the inside of the cap 6. The inside of the cap 6 has a threaded groove, and the locking ring 4 and the cap 6 form a threaded connection structure. A compression ring 60 is provided on one side of the inner cap 6. The compression ring 60 protrudes from one end of the cap 6. The compression ring 60 is opposite to the support ring 42, and the compression ring 60 is in contact with the positioning ring 7. However, the screen block forms a compression (clamping) structure with the support ring 42 and the compression ring 60, so that the inner layer 4 carries the screen block and forms a rotational movement. The cap 6 has a feed inlet 61 on one side.
[0021] Example 3: A sealing ring 81 is provided on one side of the screen blade 8. The sealing ring 81 is adjacent to the key block 80. However, the key block 80 passes through the interior of the key groove 710, which helps the sealing ring 81 and the surface of the positioning rod 71 to form a close-fitting structure, thereby reducing the amount of starch falling into the key block 80 and the position where the key groove 710 passes through.
[0022] Example 4: The bottom surface of the cross rod 70 is provided with a groove 700, the bottom surface of the screen plate 72 is provided with a groove 700, and one end of the screen blade 8 passes through the groove 700 provided in the cross rod 70 and the groove 700 provided in the screen plate 72. The screen blade 8 forms a snap-fit connection with the groove 700 provided in the cross rod 70 and the screen plate 72, which helps to improve the stability of the screen blade 8.
[0023] Example 5: The positioning rod 71 is circular in shape, and multiple screen blades 8 are provided around the positioning rod 71. The movement of the screen blades 8 helps to form a rotating movement. The clumps of starch are repeatedly dispersed (broken apart) by the rotating movement of the screen blades 8, thereby improving the processing efficiency of starch screening.
[0024] Example 6: The outer layer 3 has a discharge block 32 at its lower end, and the bottom of the discharge block 32 has a discharge port (not shown in the figure). The other end of the inner layer 4 is opposite to one end of the discharge block 32, and the inner layer 4 and the discharge block 32 are connected to each other, which helps the starch to be discharged after screening.
[0025] The discharge block 32 is conical in shape, which facilitates the starch to slide down to the discharge port and prevents starch accumulation.
[0026] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
