Abstract
Description
Technical Field
[0001] This utility model belongs to the field of starch processing technology, and specifically relates to a starch concentration device for starch processing. Background Technology
[0002] Starch processing is a complex field encompassing raw material handling, production processes, equipment application, and market expansion. Its core lies in extracting starch from plants and processing it further to meet the needs of various industries. The starch processing process requires centrifugation to concentrate the starch solution, removing water and impurities to obtain a concentrated starch solution. However, during centrifugation, the starch solution tends to form a thin film within the mesh of the screen, hindering water removal and presenting certain limitations.
[0003] A patent with publication number CN220919576U discloses a concentration device for starch processing. The device includes a storage tank, a second feeding pipe, a first feeding pipe, a screen, a first motor, a second motor, gears, a gear ring, and spiral blades. In use, starch liquid is added to the storage tank. The added starch liquid flows through the second feeding pipe into the first feeding pipe and then into the screen through the left opening of the first feeding pipe. The first motor is started, and its output shaft drives the screen to rotate via the meshing of the gear and gear ring. The second motor is then started, and its output shaft drives the first feeding pipe and the spiral blades on it to rotate. Through the rotation of the screen and the spiral blades, centrifugal operation is achieved while propelling the starch liquid.
[0004] The above-described method, through the rotation of the screen and spiral vanes, can not only guide and propel the starch solution but also centrifuge it. However, during the sieving process, the starch solution easily forms a film within the screen mesh, clogging the mesh and making it difficult for water to drain. Simultaneously, impurities in the concentrated solution may also remain within the screen mesh, affecting subsequent sieving efficiency. Utility Model Content
[0005] To address the problems existing in the background art, this utility model provides a starch concentration device for starch processing.
[0006] To achieve the above objectives, the present invention provides the following technical solution:
[0007] A starch concentration device for starch processing includes a support platform. A shell is fixedly mounted on the top of the support platform, and an outer cylinder is fixedly mounted inside the shell. A hollow tube and a sieve cylinder are rotatably inserted through the outer cylinder. A mounting block is fixedly mounted at one end of the sieve cylinder, and an elastic element is provided between the mounting block and the outer cylinder. One end of the hollow tube slides into the mounting block and is fixedly mounted with a square block. The square block is slidably positioned within the mounting block and engages with the inner wall of the mounting block. A sliding rod reciprocates within the shell, and a limiting ring is fixedly mounted on the outer surface of the sieve cylinder. One end of the sliding rod slides through the outer cylinder and is fixedly mounted with an elastic block, which engages with the limiting ring. A drive mechanism is provided on the support platform, engaging with the hollow tube and the sliding rod.
[0008] Furthermore, several through holes are opened on the outer arc surface of one end of the screen cylinder that penetrates the outer cylinder, and an inclined plate is fixedly installed below the corresponding through holes, and the inclined plate is fixedly connected to the outer shell.
[0009] Furthermore, the elastic element includes a limiting plate. The outer surface of the hollow tube is both fixedly provided with the limiting plate and fitted with a spring. The limiting plate is rotatably connected to the outer cylinder. One end of the spring is fixedly connected to the limiting plate, and the other end is fixedly connected to the mounting block.
[0010] Furthermore, the driving mechanism includes a first motor, which is fixedly mounted on the support platform, and a first pulley is fixedly mounted on the output shaft of the first motor; a second pulley is fixedly sleeved on the outer surface of the hollow tube, and a belt is sleeved between the first pulley and the second pulley for transmission.
[0011] Furthermore, the hollow tube is provided with reciprocating threads, the slide rod is threadedly engaged with the reciprocating threads, and the slide rod, the reciprocating threads and the balls constitute a ball screw.
[0012] Furthermore, a second motor is fixedly installed on the outer surface of the screen cylinder, and the output shaft of the second motor extends rotatably into the screen cylinder; an auger is rotatably installed inside the screen cylinder, and the built-in rotating shaft of the auger is coaxially and fixedly connected to the output shaft of the second motor.
[0013] Furthermore, a water outlet pipe is fixedly connected to the outer cylinder, and an inlet pipe is inserted into the hollow tube. One end of the inlet pipe rotates through the square block, the side wall of the mounting block, and the side wall of the screen cylinder in sequence, and is rotatably connected to the side wall of the screen cylinder through a bearing.
[0014] This application has the following beneficial effects:
[0015] 1. During the rotation of the screen cylinder driven by the drive mechanism, the slide bar slides back and forth along the central axis of the screen cylinder, thereby using the elastic block to push the limiting ring, so that the screen cylinder and the mounting block slide synchronously and pull the elastic element. When the mounting block abuts against the square block, with the push of the slide bar, the elastic block will deform and pass over the limiting ring, so that the screen cylinder and the mounting block are reset and oscillate back and forth multiple times under the action of the elasticity and inertia of the elastic element. Thus, the square block collides with the mounting block multiple times, so that the film formed on the surface of the screen cylinder is broken due to inertia and collision, which makes it easier for the water in the starch solution to be thrown out under the action of centrifugal force.
[0016] 2. The reciprocating shaking and collision of the sieve cylinder makes it easier for impurities in the sieve holes to be discharged, resulting in better practical effect.
[0017] 3. The reciprocating shaking of the sieve cylinder makes it easier for the concentrated starch solution to be discharged from the through hole at the end of the sieve cylinder, further improving the practical effect of the device. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Those skilled in the art should understand that the embodiments described below are only some, not all, of the embodiments disclosed. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.
[0028] like Figures 1-6 As shown, the technical solution adopted by this utility model is as follows: A starch concentration device for starch processing includes a support platform 1, a shell 2 fixedly installed on the top of the support platform 1, an outer cylinder 10 fixedly installed inside the shell 2, and a hollow tube 22 and a sieve cylinder 16 rotatably installed inside the outer cylinder 10 in a horizontal direction. Figure 3 As shown, the hollow tube 22 passes through the left side of the outer cylinder 10, and the sieve cylinder 16 passes through the right side of the outer cylinder 10. Several through holes (not labeled in the figure) are opened on the outer arc surface of the end of the sieve cylinder 16 that passes through the outer cylinder 10. An inclined plate 6 is fixedly installed below the corresponding through holes, and the inclined plate 6 is fixedly connected to the outer shell 2.
[0029] A support ring 9 is fixedly installed inside the outer cylinder 10. The support ring 9 is sleeved on the outer surface of the screen cylinder 16. The screen cylinder 16 can rotate inside the outer cylinder 10 and slide inside the outer cylinder 10.
[0030] One end of the screen cylinder 16 is fixedly provided with a mounting block 17. An elastic element is provided between the mounting block 17 and the outer cylinder 10. One end of the hollow tube 22 extends slidably into the mounting block 17 and is fixedly provided with a square block 19. The square block 19 is limited and slidably provided in the mounting block 17 and engages with the inner wall of the mounting block 17.
[0031] The elastic element includes a limiting plate 21. The outer surface of the hollow tube 22 is fixedly provided with the limiting plate 21 and also fitted with a spring 20. The limiting plate 21 is rotatably connected to the outer cylinder 10. One end of the spring 20 is fixedly connected to the limiting plate 21 and the other end is fixedly connected to the mounting block 17.
[0032] Furthermore, an elastic part 18 is provided on the side of the square block 19 that is not connected to the hollow tube 22. The elastic part 18 can not only play a protective role and prevent the square block 19 from directly colliding with the inner wall of the mounting block 17, but also provide elastic power for the square block 19 to reset.
[0033] An L-shaped slide rod 23 is reciprocated horizontally inside the outer casing 2. A limiting ring 11 is fixedly installed on the outer surface of the screen cylinder 16. One end of the slide rod 23 slides through the outer cylinder 10 and is fixedly installed with an elastic block 24. The elastic block 24 and the limiting ring 11 are in abutting and transmission cooperation.
[0034] The support platform 1 is equipped with a drive mechanism, which is in transmission cooperation with the hollow tube 22, and the hollow tube 22 is in transmission cooperation with the slide rod 23.
[0035] The drive mechanism includes a first motor 4, which is fixedly mounted on the support platform 1. The output shaft of the first motor 4 is fixedly fitted with a first pulley 15. A second pulley 12 is fixedly sleeved on the outer surface of the hollow tube 22, and a belt 14 is sleeved between the first pulley 15 and the second pulley 12 for transmission.
[0036] The hollow tube 22 has a reciprocating thread 13, and the slide rod 23 is threadedly engaged with the reciprocating thread 13. The slide rod 23, the reciprocating thread 13, and the balls form a ball screw pair.
[0037] A second motor 7 is fixedly installed on the outer surface of the screen cylinder 16, and the output shaft of the second motor 7 extends rotatably into the screen cylinder 16; an auger 8 is rotatably installed inside the screen cylinder 16, and the built-in rotating shaft of the auger 8 is coaxially and fixedly connected to the output shaft of the second motor 7.
[0038] In addition, a water outlet pipe 5 is fixedly connected to the outer cylinder 10, and an inlet pipe 3 is inserted into the hollow tube 22. One end of the inlet pipe 3 rotates through the square block 19, the elastic part 18, the side wall of the mounting block 17 and the side wall of the screen cylinder 16 in sequence, and is rotatably connected to the side wall of the screen cylinder 16 through a bearing.
[0039] It should be noted that the hollow tube 22 includes a rigid tube and a corrugated tube. The rigid tube of the hollow tube 22 is rotatably connected to the side wall of the sieve cylinder 16 through a bearing, and the corrugated tube of the hollow tube 22 is located outside the outer shell 2 and is connected to the infusion equipment through a rotating joint.
[0040] Working principle: In use, the starch solution to be concentrated is injected into the sieve cylinder 16 through the inlet pipe 3. The first motor 4 is started, and the output shaft of the first motor 4 drives the first pulley 15 to rotate. With the transmission of the belt 14 and the second pulley 12, the hollow tube 22 rotates. The rotation of the hollow tube 22 drives the sieve cylinder 16 to rotate through the square block 19 and the mounting block 17. The rotation of the sieve cylinder 16 can use centrifugal force to throw out excess water and impurities in the starch solution, so that the concentrated starch solution remains in the sieve cylinder 16, while the water and impurities thrown between the outer cylinder 10 and the sieve cylinder 16 are discharged through the water outlet pipe 5.
[0041] During this process, the second motor 7 is started, and the output shaft of the second motor 7 drives the auger 8 to rotate, so that the concentrated starch liquid in the sieve cylinder 16 is transported from the left side of the sieve cylinder 16 to the right side of the sieve cylinder 16. The sieve cylinder 16 continues to rotate during the process of the auger 8 transporting the concentrated starch liquid, so that the concentrated starch liquid being transported is continuously concentrated by centrifugal force. When the concentrated starch liquid is transported to the right side of the sieve cylinder 16, the concentrated starch liquid will flow out through the through hole opened on the right side of the sieve cylinder 16 and fall onto the inclined plate 6.
[0042] Because the inclined plate 6 is set at an angle, the concentrated starch liquid that falls on the inclined plate 6 will slide out along the inclined surface of the inclined plate 6, thereby completing the collection operation of the concentrated starch liquid.
[0043] In addition, the rotation of the hollow tube 22 will also drive the reciprocating thread 13 to rotate. Since the reciprocating thread 13 has a sliding rod 23 connected to its surface, the rotation of the reciprocating thread 13 will drive the sliding rod 23 to slide back and forth along the central axis of the hollow tube 22.
[0044] like Figure 5 The initial state shown (the left and right directions below are all based on) Figure 5 (As shown in the direction), at this time, spring 20 is in its natural state, slide bar 23 is located at the leftmost position of reciprocating thread 13, and elastic block 24 abuts against limiting ring 11. Subsequently, the rotation of hollow tube 22 will drive slide bar 23 to move to the right. Since limiting ring 11 abuts against elastic block 24, the movement of slide bar 23 will push screen cylinder 16 to the right through limiting ring 11 and lengthen the corrugated pipe on inlet pipe 3, causing mounting block 17 to move to the right and stretch spring 20.
[0045] When the left inner wall of the mounting block 17 abuts against the square block 19, the screen cylinder 16 stops moving. As the slide rod 23 continues to move to the right, the elastic block 24 deforms and gradually passes the limiting ring 11. When the elastic block 24 completely passes the limiting ring 11, the limiting ring 11 loses the obstruction of the left elastic block 24. The mounting block 17 and the screen cylinder 16 will quickly move to the left and reset under the elastic action of the spring 20. Under the action of inertia, the mounting block 17 and the screen cylinder 16 will move to the left a greater distance, causing the elastic part 18 of the square block 19 to collide with the right inner wall of the mounting block 17 and generate compression, causing the elastic part 18 to deform and the spring 20 to be compressed.
[0046] Immediately following, under the elastic action of spring 20 and elastic part 18, mounting block 17 and sieve cylinder 16 move to the right again, causing square block 19 to collide with the left inner wall of mounting block 17 and pull spring 20. This process repeats (the distance of each movement decreases), causing mounting block 17 and sieve cylinder 16 to shake rapidly several times. Through the shaking of sieve cylinder 16 and the impact force generated by the collision of square block 19, the film formed on the surface of sieve cylinder 16 is broken due to inertia and collision, making it easier for the water in the starch solution to be thrown out under the action of centrifugal force.
[0047] In addition, it can be seen from the initial state that when the spring 20 is in its natural state, the square block 19 is relatively close to the inner wall of the right side of the mounting block 17.
[0048] When the slide bar 23 moves to the left, the elastic block 24 on the slide bar 23 will move from the right side of the limiting ring 11 to the left side. Since the square block 19 is close to the inner wall of the right side of the mounting block 17, the swaying of the screen cylinder 16 from side to side can be ignored.
[0049] When the slide bar 23 moves to the right again, the elastic block 24 on the slide bar 23 will move from the left side to the right side of the limiting ring 11, causing the screen cylinder 16 to sway left and right to repeat the above effect.
[0050] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
