Description

Technical Field

[0001] The utility model relates to the technical field of corn starch production. Specifically, it relates to a device for recovering and breaking damaged corn steep liquor in corn starch production. Background Art

[0002] Corn starch, a natural polysaccharide derived from corn, occupies an important position in fields such as food processing, pharmaceutical manufacturing, papermaking, and chemical production due to its wide applicability and versatility. Its production process can be summarized as follows: In the initial stage, corn is pretreated, including cleaning, soaking, and crushing to separate starch and other components. Subsequently, corn steep liquor rich in starch is obtained through wet milling, and this slurry is the basis for subsequent processing. Then, it enters the starch extraction stage, where pure starch granules are separated from the corn steep liquor using techniques such as screening and centrifugation. Finally, through a series of refining steps, including washing, dehydration, and drying, high-quality corn starch products are ultimately obtained. In this series of production links, the device for recovering and breaking damaged corn steep liquor plays an indispensable role. Their effectiveness is directly related to the smooth operation of the entire production chain and the excellent characteristics of the produced starch, and is the key to achieving efficient and high-quality production of corn starch.

[0003] For example, Chinese Patent CN214765694U discloses a device for recovering and breaking damaged corn steep liquor in xylitol production, including a base, a bracket, a motor, a connecting shaft, a separation mechanism, a connecting pipe, and a spray head. By starting the second motor, the second connecting shaft and the transmission wheel rotate accordingly, driving the grinding rod to grind. After grinding, the raw materials enter the separation box at the discharge port, and then by starting the first motor, the first connecting shaft and the rotating shaft rotate to separate the raw materials, improving work efficiency and work output. However, during the process of recovering and breaking of the above device for recovering and breaking damaged corn steep liquor, the raw materials after grinding are directly sent into the separation box, and the corn grains that do not meet the breaking standard are not effectively screened for secondary processing, which may lead to some corn grains not being fully utilized, resulting in waste of raw materials and indirectly increasing production costs, having an adverse impact on economic benefits.

[0004] Regarding the problems in the related technology, no effective solution has been proposed yet. Summary of the Utility Model

[0005] Regarding the problems in the related technology, the utility model proposes a device for recovering and breaking damaged corn steep liquor in corn starch production to overcome the above-mentioned technical problems existing in the existing related technology.

[0006] Therefore, the specific technical solution adopted by the utility model is as follows:

[0007] A corn steep liquor recovery and breakage device for corn starch production, comprising a recovery box. Inside the recovery box, a breakage mechanism and a filtering mechanism are sequentially arranged from top to bottom. A water inlet pipe penetrates through the top of the recovery box. A feed pipe is arranged at the top of one end of the recovery box. A discharge pipe penetrates through the bottom of the other end of the recovery box. A slag collection box is arranged on one side of the recovery box.

[0008] Furthermore, in order to prevent waste of raw materials and ensure the production efficiency of corn starch, under the rotation of the output shaft of the motor, the driving gear rotates, causing the two breakage rollers to squeeze each other, thereby realizing the breakage and grinding of corn grains in the breakage box. The broken corn grains are then screened by the filter cylinder. The qualified broken corn grains can pass through the filter cylinder and fall onto the filtering mechanism for filtering, while the unqualified unbroken corn grains will be left inside the filter cylinder. Under the blocking of the baffle and the rotation of the filter cylinder, these grains will be redirected to the top of the breakage box and go through the breakage and grinding process again, thereby ensuring that all raw materials can achieve the predetermined breakage effect, minimizing waste of raw materials to the greatest extent, and at the same time maintaining the consistency and quality of corn starch production. The breakage mechanism includes a filter cylinder inserted through the inner top of the recovery box. Inside the filter cylinder, there is a breakage box. Inside the breakage box, breakage rollers are symmetrically inserted. On the inner wall of the filter cylinder, there are several baffles. On one end inner wall of the filter cylinder, several tooth grooves are opened. On one side of the tooth grooves, a driven gear one is meshed. On one side of the driven gear one, a driven gear two is meshed. On one side of the driven gear two, a driving gear is meshed. The driving gear is connected to the output shaft of the motor. One group of breakage rollers is connected to the driven gear two, and the other group of breakage rollers is connected to the driving gear.

[0009] Furthermore, in order to improve the efficiency of separating the crushed corn particles from the corn slurry, under the action of the contraction of the electric telescopic rod, the push block can move away from the extrusion block, and under the cooperation of the limit block and the limit groove, the two extrusion blocks are driven to move. At the same time, under the cooperation of the clamping block and the clamping groove, the two extrusion blocks approach each other along the path of the clamping groove, so that the two extrusion plates approach each other, exerting a uniform pressure on the corn particles on the filter plate, prompting the corn slurry to quickly seep out from between the particles, thereby accelerating the extraction speed of the corn slurry, and further improving the overall efficiency of the corn slurry recovery and damage treatment. The filtering mechanism includes a filter plate arranged below the damage mechanism. The top of the filter plate is symmetrically provided with extrusion plates. One end of the extrusion plate is provided with an extrusion block. A push block is arranged between the two extrusion blocks. The end of the push block away from the extrusion block is connected with an electric telescopic rod. On the outer side of the extrusion block and on the other side of the recovery box, a limit frame is arranged. Clamping blocks are arranged at the top and bottom of the extrusion block. A clamping groove matched with the clamping block is arranged inside the limit frame. The other end of the push block is symmetrically provided with limit blocks. A limit groove matched with the limit block is arranged at one end of the extrusion block. The cross section of the push block is a trapezoidal structure. The cross section of the limit block is a trapezoidal structure. A notch matched with the filter plate is arranged on one side of the recovery box and inside the slag collection box.

[0010] The beneficial effects of the present utility model are as follows:

[0011] 1. Through the combined setting of the damage mechanism and the filtering mechanism, the present utility model can not only perform secondary processing on the corn particles that fail to meet the standard in the initial damage and grinding, effectively preventing raw material loss caused by insufficient damage and ensuring that every portion of the raw material can be fully utilized; but also can accelerate the seepage rate of the corn slurry through extrusion, significantly improving the efficiency of corn slurry recovery and subsequent processing, and further enhancing the efficiency and economy of the entire corn starch production.

[0012] 2. By setting the damage mechanism, under the rotation of the output shaft of the motor, the driving gear can be rotated, enabling the two damage rollers to squeeze each other, thereby realizing the damage and grinding of the corn particles in the damage box. The crushed corn particles are immediately screened by the filter cylinder. The qualified damaged corn particles can pass through the filter cylinder and fall onto the filtering mechanism for filtering, while the unqualified undamaged corn particles will be left in the filter cylinder. Under the blocking of the baffle and the rotation of the filter cylinder, these particles will be redirected to the top of the damage box and go through the damage and grinding process again, thereby ensuring that all raw materials can reach the predetermined crushing effect, minimizing raw material waste to the greatest extent, and at the same time maintaining the consistency and quality of corn starch production.

[0013] 3. By setting up a filtering mechanism, under the action of the contraction of the electric telescopic rod, the pushing block can move away from the extrusion block. Under the combined action of the limiting block and the limiting groove, the two extrusion blocks are driven to move. At the same time, under the combined action of the clamping block and the clamping groove, the two extrusion blocks approach each other along the path of the clamping groove, so that the two extrusion plates approach each other, exerting a uniform pressure on the corn kernels on the filter plate, prompting the corn slurry to quickly seep out from between the kernels, thus accelerating the extraction speed of the corn slurry and further improving the overall efficiency of the corn slurry recovery and breakage treatment.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] To further illustrate each embodiment, the present utility model provides attached drawings, which are a part of the disclosure of the present utility model. These drawings are mainly used to illustrate the embodiments and can be combined with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those of ordinary skill in the art should be able to understand other possible implementation manners and the advantages of the present utility model. The components in the drawings are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0022] According to an embodiment of the present utility model, there is provided a device for recovering and breaking damaged corn steep liquor in corn starch production.

[0023] Now, the present utility model will be further described in conjunction with the attached drawings and specific implementation manners. As Figures 1-4 shown, the device for recovering and breaking damaged corn steep liquor in corn starch production according to an embodiment of the present utility model includes a recovery tank 1. Inside the recovery tank 1, a breaking mechanism 2 and a filtering mechanism 3 are sequentially arranged from top to bottom. A water inlet pipe 4 penetrates through the top of the recovery tank 1. A feed pipe 5 is arranged at the top of one end of the recovery tank 1. A discharge pipe 6 penetrates through the bottom of the other end of the recovery tank 1. A slag collection tank 7 is arranged on one side of the recovery tank 1.

[0024] By means of the above technical solution of the present utility model, through the coordinated setting of the breaking mechanism 2 and the filtering mechanism 3, the present utility model can not only perform secondary processing on corn grains that fail to meet the standard after the initial breaking and grinding, effectively prevent raw material loss caused by insufficient breaking, and ensure that every portion of raw material can be fully utilized; but also accelerate the seepage rate of corn steep liquor through extrusion, significantly improve the efficiency of corn steep liquor recovery and subsequent processing, and thus enhance the efficiency and economy of the entire corn starch production.

[0025] In one embodiment, for the above-mentioned breaking mechanism 2, the breaking mechanism 2 includes a filter cylinder 201 inserted through the top inside the recycling bin 1. Inside the filter cylinder 201, there is a breaking bin 202, and symmetrically inserted inside the breaking bin 202 are breaking rollers 203. On the inner wall of the filter cylinder 201, there are several baffles 204. At one end of the inner wall inside the filter cylinder 201, several tooth grooves 205 are provided. On one side of the tooth grooves 205, a first driven gear 206 is meshed. On one side of the first driven gear 206, a second driven gear 207 is meshed. On one side of the second driven gear 207, a driving gear 208 is meshed. The driving gear 208 is connected to the output shaft of the motor 209. One set of breaking rollers 203 is connected to the second driven gear 207, and the other set of breaking rollers 203 is connected to the driving gear 208. Under the rotation of the output shaft of the motor 209, the driving gear 208 rotates, causing the two sets of breaking rollers 203 to squeeze against each other, thereby realizing the breaking and grinding of the corn kernels inside the breaking bin 202. The broken corn kernels are then screened by the filter cylinder 201. The qualified broken corn kernels can pass through the filter cylinder 201 and fall onto the filtering mechanism 3 for filtering, while the unqualified unbroken corn kernels will be left inside the filter cylinder 201. Under the blocking of the baffles 204 and the rotation of the filter cylinder 201, these kernels will be redirected to the top of the breaking bin 202 and go through the process of breaking and grinding again, thereby ensuring that all raw materials can achieve the predetermined breaking effect, minimizing raw material waste, and maintaining the consistency and quality of corn starch production at the same time.

[0026] In addition, it should be noted that in order for the raw materials to fall into the breaking bin 202 for breaking and grinding, the above-mentioned feed pipe 5 is inclined and arranged inside the filter cylinder 201 and above the breaking bin 202.

[0027] The working principle of the breaking mechanism 2: By starting the motor 209, under the rotation of the output shaft of the motor 209, the driving gear 208 rotates, driving the meshed second driven gear 207 to rotate, causing the two sets of breaking rollers 203 to squeeze against each other, realizing the precise breaking and grinding of the corn kernels inside the breaking bin 202. The broken corn kernels are then screened by the filter cylinder 201. Then, the qualified broken corn kernels can pass through the filter cylinder 201 and fall onto the filtering mechanism 3 for filtering, while the unqualified unbroken corn kernels will be left inside the filter cylinder 201. At the same time, the first driven gear 206 meshed with the second driven gear 207 also rotates. Under the meshing action of the tooth grooves 205, the filter cylinder 201 rotates. At the same time, under the blocking action of the baffles 204, the unqualified unbroken corn kernels are rotated to the top of the breaking bin 202 again and fall into the breaking bin 202 for secondary breaking, thereby realizing the secondary breaking process for the unqualified broken corn kernels, and further realizing the reduction of raw material waste and ensuring the quality of corn starch production.

[0028] In one embodiment, for the above-mentioned filtering mechanism 3, the filtering mechanism 3 includes a filter plate 301 disposed below the breaking mechanism 2. Symmetrically arranged at the top end of the filter plate 301 are pressing plates 302. At one end of each pressing plate 302 is arranged a pressing block 303. Between the two groups of pressing blocks 303 is arranged a pushing block 304. Connected to the end of the pushing block 304 away from the pressing block 303 is an electric telescopic rod 305. On the outer side of the pressing block 303 and on the other side of the recycling box 1 is arranged a limiting frame 306. At the top and bottom ends of the pressing block 303 are arranged clamping blocks 307. Inside the limiting frame 306 is arranged a clamping groove 308 that cooperates with the clamping block 307. Symmetrically arranged at the other end of the pushing block 304 are limiting blocks 309. At one end of the pressing block 303 is formed a limiting groove 310 that cooperates with the limiting block 309. The cross-section of the pushing block 304 is a trapezoidal structure. The cross-section of the limiting block 309 is a trapezoidal structure. On one side of the recycling box 1 and inside the slag collecting box 7 is formed a notch 701 that cooperates with the filter plate 301. Under the action of the contraction of the electric telescopic rod 305, the pushing block 304 can move in a direction away from the pressing block 303. Under the combined action of the limiting block 309 and the limiting groove 310, the two groups of pressing blocks 303 are driven to move. At the same time, under the combined action of the clamping block 307 and the clamping groove 308, the two groups of pressing blocks 303 approach each other along the path of the clamping groove 308, so that the two groups of pressing plates 302 approach each other, applying a uniform pressure to the corn kernels on the filter plate 301, prompting the corn slurry to quickly seep out from between the kernels, thereby accelerating the extraction speed of the corn slurry and further improving the overall efficiency of the recycling and breaking treatment of the corn slurry.

[0029] In addition, it should be noted that the above-mentioned electric telescopic rod 305 is composed of an electric motor, a reduction gear set, a telescopic rod body, a door body positioning sensor, a limit switch, a control unit and a power supply. The working principle of the electric telescopic rod 305 is to convert the rotational motion into a linear driving force through the reduction gear set, and push the pipe sections inside the telescopic rod body to extend or retract in sequence. The composition and working principle of this electric telescopic rod 305 are prior art and will not be elaborated here.

[0030] Working principle of the filtering mechanism 3: By starting the electric telescopic rod 305, under the action of the contraction of the electric telescopic rod 305, the push block 304 moves away from the extrusion block 303, and under the cooperation of the limit block 309 and the limit groove 310, the two extrusion blocks 303 are driven to move. At the same time, under the cooperation of the clamping block 307 and the clamping groove 308, the two extrusion blocks 303 approach each other along the path of the clamping groove 308 until the two extrusion plates 302 are in close contact, applying uniform and effective pressure to the corn kernels located on the filter plate 301, prompting the corn slurry to quickly precipitate from the particle gaps, significantly improving the seepage rate of the corn slurry, thus greatly accelerating the extraction process of the corn slurry, improving the overall breakage treatment efficiency. After the extrusion is completed, the electric telescopic rod 305 returns to the extended state, and reverse operation makes the two extrusion plates 302 separate from each other, and at the same time makes the push block 304 move towards the extrusion block 303, assisting in guiding the extruded corn kernels into the slag collection box 7 through the notch 701 for subsequent treatment or recycling.

[0031] To facilitate the understanding of the above technical solutions of the present invention, the working principle or operation method of the present invention in the actual process will be described in detail below.

[0032] In actual application, the operator passes an appropriate amount of water into the recovery box 1 through the water inlet pipe 4, and at the same time feeds the corn raw materials through the feed pipe 5, then starts the breakage mechanism 2 for breakage and grinding, and at the same time starts the filtering mechanism 3 to separate the corn slurry from the ground mixture. At the same time, the operator regularly cleans the slag collection box 7, and finally discharges the obtained corn slurry through the discharge pipe 6 into the next production process of corn starch.

[0033] In summary, by means of the above technical solution of the present utility model, through the cooperative setting of the breaking mechanism 2 and the filtering mechanism 3, it is not only possible to perform secondary processing on the corn kernels that fail to meet the standards after the initial breaking and grinding, effectively preventing raw material loss caused by insufficient breaking and ensuring that every portion of raw material can be fully utilized; but also capable of accelerating the seepage rate of corn slurry through extrusion, significantly improving the efficiency of corn slurry recovery and subsequent processing, and thereby enhancing the efficiency and economy of the entire corn starch production; by setting the breaking mechanism 2, under the rotation of the output shaft of the motor 209, the driving gear 208 can be rotated, causing the two breaking rollers 203 to squeeze each other, thereby realizing the breaking and grinding of the corn kernels in the breaking box 202. The broken corn kernels will then be screened by the filter cylinder 201. The qualified broken corn kernels can pass through the filter cylinder 201 and fall onto the filtering mechanism 3 for filtering, while the unqualified unbroken corn kernels will be left in the filter cylinder 201. Under the blocking of the baffle 204 and the rotation of the filter cylinder 201, these kernels will be redirected to the top of the breaking box 202 and undergo the process of breaking and grinding again, thereby ensuring that all raw materials can achieve the predetermined breaking effect, minimizing raw material waste to the greatest extent, and at the same time maintaining the consistency and quality of corn starch production; by setting the filtering mechanism 3, under the contraction of the electric telescopic rod 305, the push block 304 can move away from the extrusion block 303, and under the cooperative action of the limit block 309 and the limit groove 310, drive the two extrusion blocks 303 to move. At the same time, under the cooperative action of the clamping block 307 and the clamping groove 308, the two extrusion blocks 303 approach each other along the path of the clamping groove 308, so that the two extrusion plates 302 approach each other, exerting uniform pressure on the corn kernels on the filter plate 301, prompting the corn slurry to quickly seep out from between the kernels, thereby accelerating the extraction speed of the corn slurry and further improving the overall efficiency of corn slurry recovery and breaking treatment.
