Description

Technical Field

[0001] The present invention belongs to the technical field of starch preparation, and particularly relates to a pulp residue separation system for preparing soluble starch. Background Art

[0002] Starch is an important component of food and the main source of human thermal energy. Starch is also the raw material and auxiliary material for many industrial productions. Its main available properties include granule properties, paste or slurry properties, film-forming properties, etc. Since natural starch does not fully possess the effective properties required for applications in various industrial sectors, according to the structures, physical and chemical properties, and application requirements of different types of starch, corresponding technologies can be used to modify it to obtain various modified starches, thereby improving the application effect and expanding the application scope. Starch and modified starch can be widely applied in many industries such as food, textile, papermaking, medicine, chemical industry, building materials, oil drilling, casting, and agriculture.

[0003] In the Chinese patent with the publication number CN220047257U, a starch pulp residue separation structure is mentioned. Its specification discloses that when the output shaft of the hydraulic push rod starts to contract, the lifting plate located at the top of the separation box descends. The lifting plate drives the cover pressing plate to descend through the connecting plate and the sealing cover. The cover pressing plate is located on the inner wall of the top of the mesh box. The output shaft of the motor drives the rotating rod to rotate, the rotating rod drives the driving gear to rotate, the driving gear drives the rotating shaft to rotate through the driven gear, and the rotating shaft drives the pulp blades to rotate and stir the pulp residue in the mesh box, which can disperse the pulp residue, fully mix the residual starch in the pulp residue with water, and fully separate the pulp residue from the starch.

[0004] However, in the above application, although the crushed pulp residue is filtered through the filter screen to remove most of the unnecessary solid particles, since the above application grinds and filters at the same time, some crushed residues are prone to move, resulting in some smaller crushed residue particles that may accidentally pass through the pores of the filter screen and fall into the filtered liquid. After these fine crushed residues are mixed with the starch solution, they may affect the quality and purity of the final product, resulting in an uneven particle distribution in the starch solution, and further affecting the reaction effect or the physical properties of the product in the subsequent process flow.

[0015] Preferably: A limiting rod is fixedly connected to the surface of the bracket. The cross-sectional shape of the limiting rod is L-shaped, and the end of the limiting rod away from the bracket slidably penetrates through the slide plate.

[0016] Preferably, a plurality of sliding grooves are formed in the inner wall of the gear, and tooth blocks are slidably connected to the inner walls of the sliding grooves.

[0022] 3. Through the tooth blocks, the connecting ropes, the second spring, the plug rod, the insertion holes and the grip rod, by rotating the grip rod, the tooth blocks can be contracted, reducing the number of teeth of the gear, so that the gear cooperates with the rack to complete the vibration of the tank body. Under the action of the second spring, the tooth blocks can rebound, increasing the number of teeth of the gear. By changing the position of the cleaning brush, the cleaning brush contacts the second filter screen, and through the transmission of the gear and the rack, the cleaning of the second filter screen is completed.

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] Refer to Figures 1 - 7As shown in the figure, the present invention provides a slurry residue separation system for preparing soluble starch, including a bracket 1. A tank body 101 and a vertical plate 104 are installed on the surface of the bracket 1. A circular frame 102 is arranged inside the tank body 101. A first filter screen 103 is installed at the bottom of the circular frame 102. An electric push rod 105 is installed on the surface of the vertical plate 104. The output end of the electric push rod 105 is fixedly connected to a first motor 106. The output end of the first motor 106 is fixedly connected to a grinding plate 107. It further includes:

[0033] Two support plates 108, which are used to support the circular frame 102 after the circular frame 102 enters the tank body 101. The two support plates 108 are both fixedly connected to the inner arc surface of the tank body 101, and the two support plates 108 are symmetrically distributed with respect to the vertical central axis of the tank body 101;

[0034] In this embodiment, the material is ground and rolled by the grinding plate 107, so as to extrude the starch solution, playing a role in separating the slurry from the residue. The circular frame 102 is in a straight-through state at both the upper and lower ends, and only the first filter screen 103 is installed at the bottom of the circular frame 102, playing a preliminary filtering role.

[0035] In a further embodiment, referring to Figure 1 、 Figure 2 and Figure 3 As shown in the figure, an auxiliary mechanism 2. The auxiliary mechanism 2 includes four fixing blocks 201 fixedly connected to the end face of the circular frame 102. The four fixing blocks 201 are grouped in pairs. A rotating rod 202 is rotatably connected to the surface of the fixing blocks 201 in the same group. A clamping plate 203 is fixedly connected to the arc surface of the rotating rod 202; A torsion spring 204 is sleeved on the arc surface of the rotating rod 202, and both ends of the torsion spring 204 are fixedly connected to the rotating rod 202 and one of the fixing blocks 201 respectively.

[0036] In this embodiment, the cross-sectional shape of the clamping plate 203 is in the shape of the number 7, which is more conducive to being fixed on the grinding plate 107. With the resistance of the torsion spring 204, when the grinding plate 107 rises, the circular frame 102 can be lifted together, which is conducive to directly cleaning the residue inside the circular frame 102.

[0037] Two long rods 205 are fixedly connected to the surface of the bracket 1. The ends of the two long rods 205 close to each other are rotatably connected to a circular ring 206. A second filter screen 207 is fixedly connected to the inner arc surface of the circular ring 206.

[0038] In this embodiment, by rotating the long rod 205, the second filter screen 207 can be flipped, which is convenient for cleaning the other side of the second filter screen 207. The second filter screen 207 plays a role in filtering the starch solution again.

[0039] In a further embodiment, referring to Figure 4 、 Figure 5 、 Figure 6 andFigure 7 As shown in Figure 7 , the vibration cleaning mechanism 3 is used to vibrate the tank body 101 to facilitate the falling of pulp residue on its inner wall, and can also be converted into a cleaning component for use. The vibration cleaning mechanism 3 includes a third motor 304 located on one side of the tank body 101. The output end of the third motor 304 is fixedly connected with a gear 305. The tooth surface of the gear 305 is meshed with a rack 306. One side of the rack 306 away from the gear 305 is fixedly connected with a fixing plate 307. Two cleaning brushes 312 are rotatably connected to the surface of the fixing plate 307. Arc plates 313 are fixedly connected to one side of the two cleaning brushes 312 close to each other.

[0040] In this embodiment, only a few teeth are provided on the tooth surface of the gear 305, which is beneficial to realizing reciprocating motion when cooperating with the rack 306 for transmission.

[0041] A second motor 301 is fixedly connected to the surface of the bracket 1. The output end of the second motor 301 is fixedly connected with a threaded rod 302. A slide plate 303 is threadedly connected to the arc surface of the threaded rod 302. The third motor 304 is fixedly connected to the end face of the slide plate 303.

[0042] A round rod 308 is slidably inserted into the surface of the fixing plate 307. One end of the round rod 308 is fixedly connected with a sliding tube 310. A fixing rod 311 is slidably connected to the inner wall of the sliding tube 310. The fixing rod 311 is fixedly connected to the surface of the bracket 1. A first spring 309 is sleeved on the arc surface of the round rod 308. The two ends of the first spring 309 are respectively fixedly connected with the fixing plate 307 and the round rod 308.

[0043] In this embodiment, there is damping between the sliding tube 310 and the fixing rod 311, which can be stabilized by means of its own frictional force and is not easy to slide without external force.

[0044] A limiting rod 314 is fixedly connected to the surface of the bracket 1. The cross-sectional shape of the limiting rod 314 is L-shaped. One end of the limiting rod 314 away from the bracket 1 slidably penetrates through the slide plate 303.

[0045] In this embodiment, when the slide plate 303 moves, it will slide along the surface of the limiting rod 314, and the limiting rod 314 plays a role in restricting the position of the slide plate 303.

[0046] A plurality of sliding grooves 315 are formed in the inner wall of the gear 305. Tooth blocks 316 are slidably connected to the inner walls of the sliding grooves 315. One end of each tooth block 316 is fixedly connected to a second spring 317, and the second spring 317 is fixedly connected to the inner wall of the sliding groove 315. A grip rod 319 is rotatably connected to the end face of the gear 305. A plurality of connecting ropes 318 are fixedly connected to the arc surface of the grip rod 319. The ends of the plurality of connecting ropes 318 away from the grip rod 319 are respectively fixedly connected to the plurality of tooth blocks 316. A circular plate 320 is fixedly connected to the top end of the grip rod 319. A plug rod 321 is slidably inserted into the end face of the circular plate 320. A plurality of jacks 322 are formed in the end face of the gear 305. The plurality of jacks 322 are circumferentially formed in the end face of the gear 305, and the size of the jacks 322 is adapted to the size of the plug rod 321.

[0047] In this embodiment, the tooth blocks 316 can contract on the arc surface of the gear 305. When all the tooth blocks 316 extend out, they can form a complete one. In this state, when driving with the rack 306, the moving distance of the rack 306 can be farther, and the cleaning of the second filter screen 207 can be realized. That is, the gear 305 has two states and can realize two different functions.

[0048] The working principle of the present invention is as follows: When in use, the staff puts materials such as potatoes or sweet potatoes into the circular frame 102, starts the electric push rod 105, and the electric push rod 105 drives the first motor 106 to move downward. As the first motor 106 drives the grinding plate 107 to move downward, since the clamping plate 203 is placed on the grinding plate 107, the circular frame 102 will also move downward until the bottom of the circular frame 102 touches the support plate 108. As the grinding plate 107 continues to move downward, the clamping plate 203 disengages from the contact with the grinding plate 107. Then start the first motor 106, and the grinding plate 107 rotates and moves downward at the same time, and will extrude and grind the materials inside the circular frame 102, so as to squeeze out the starch inside the materials. The starch solution will drip through the first filter screen 103, and most of the residues will remain in the circular frame 102, and a small part of the residues may fall out through the gaps of the first filter screen 103. The starch solution will flow out from the bottom of the tank body 101 and pass through the second filter screen 207 for further filtration, and the residues in the starch solution will remain on the second filter screen 207. When the materials in the circular frame 102 are squeezed out, the electric push rod 105 drives the grinding plate 107 to move upward. As the grinding plate 107 moves upward, the grinding plate 107 will contact the clamping plate 203. Due to the special shape of the clamping plate 203 and the resistance of the torsion spring 204, the clamping plate 203 will be placed on the grinding plate 107, and then the circular frame 102 will move upward until the circular frame 102 is exposed outside the tank body 101. At this time, it is convenient for the staff to remove the circular frame 102 to facilitate the cleaning of the residues inside the circular frame 102;

[0049] When it is necessary to clean the residue adsorbed on the inner wall of the tank body 101, rotate the grip rod 319. When the grip rod 319 rotates, it will wind the connecting rope 318. When the connecting rope 318 is wound up, it will drive the tooth block 316 to slide along the inner wall of the chute 315. Multiple tooth blocks 316 will slowly contract. At this time, only a few teeth are on the tooth surface of the gear 305, and the second spring 317 is in a compressed state. Finally, insert the insertion rod 321 into the insertion hole 322 to stabilize the grip rod 319. Start the third motor 304 to drive the gear 305 to rotate and drive the rack 306. Under the action of the first spring 309, the fixing plate 307 will move back and forth repeatedly. Then the arc plate 313 will repeatedly impact the tank body 101, causing the tank body 101 to vibrate, which is beneficial to the residue adsorbed on the inner wall of the tank body 101 to fall and fall on the second filter screen 207. When it is necessary to clean the residue on the second filter screen 207, start the second motor 301 to drive the threaded rod 302 to rotate. With the drive of the thread, the slide plate 303 moves downward. With the movement of the slide tube 310, the fixing plate 307 also moves downward. Then rotate the angle of the cleaning brush 312 so that the brush surface of the cleaning brush 312 is flush with the end face of the second filter screen 207. At this time, pull out the insertion rod 321 from the insertion hole 322. The second spring 317 will rebound at this time, and then the tooth block 316 will pop out and be flush with the teeth on the gear 305. At this time, start the third motor 304 to drive the gear 305 to rotate and drive the rack 306 again. The cleaning brush 312 will move, and the cleaning of the second filter screen 207 can be realized. Reverse the rotation of the output shaft of the third motor 304, and the cleaning brush 312 can return to its original position. With the rotation of the long rod 205, the second filter screen 207 can be flipped to facilitate the cleaning of the other side of the second filter screen 207.

[0050] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
