Description

Technical Field

[0001] This invention relates to the field of starch grinding equipment, and in particular to a refined grinding equipment for corn starch production. Background Technology

[0002] Corn starch has strong water absorption and certain antioxidant properties. It can regulate the viscosity of food, improve the taste of food, and delay the decomposition and spoilage of food. It is widely used in food, sugar making, fermentation, medicine and chemical industries.

[0003] The grinding of corn starch mainly refers to the grinding of corn slurry, which is the endosperm that has been crushed and separated. It consists of starch granules, gluten, seed coat, and endosperm fragments containing a large amount of starch. Grinding the slurry requires a fine grinding process to make the endosperm particles finer and to release starch bound to proteins and cellulose to a certain extent, creating conditions for separation in the next step. Existing corn starch grinding equipment mostly uses a single method or a single action, and it cannot achieve a uniform and slow feeding of the corn starch slurry during the grinding action, resulting in uneven grinding and poor grinding quality. Summary of the Invention

[0004] The purpose of this invention is to provide a fine grinding device for corn starch production, which utilizes a fine grinding component and a primary grinding component installed in the main housing, along with an automatically opening and closing top cover and a safety transmission component, to form a dual and different grinding action.

[0005] The objective of this invention is achieved through the following technical solution: a refining and grinding equipment for corn starch production, comprising a base frame, a top cover assembly, a fine grinding assembly, a primary grinding assembly, and a safety transmission component;

[0006] The base structure components include the main shell, the top cover assembly includes the top cover body, the fine grinding assembly includes fine grinding teeth, the primary grinding assembly includes a primary grinding cover, a material discharge funnel and a reset slide column, and the safety transmission components include a transmission gear, a transmission connecting toothed pulley and a transmission connecting toothed belt.

[0007] The top cover is screwed onto the top opening of the main housing. Electric cylinder fixed seats are fixed on both outer sides of the main housing, and electric cylinder movable seats are fixed on both outer sides of the top cover. The bottom body of the telescopic electric cylinder is rotatably connected to the electric cylinder fixed seat, and the top of the telescopic rod of the telescopic electric cylinder is rotatably connected to the electric cylinder movable seat.

[0008] A fine grinding shaft is horizontally screwed to the lower inner end of the main body. Fine grinding teeth are arranged and fixed outside the fine grinding shaft. The primary grinding cover is fixed to the upper inner end of the main body. The discharge funnel is horizontally screwed inside the primary grinding cover. A fixed grinding seat is arranged and fixed on the inner bottom surface of the primary grinding cover. A moving grinding seat is arranged and fixed on the outer bottom surface of the discharge funnel. A central gear is screwed to the middle of the outer side of the main body. A discharge swinging connecting rod is fixed to the outer end of the rotating shaft of the discharge funnel. The eccentric end of the central gear is slidably connected to the discharge swinging connecting rod. A reset sliding rod is also slidably elastically slid on the outer side of the main body. The reset sliding rod is slidably connected to the discharge swinging connecting rod through a reset sliding column.

[0009] The transmission gear is screwed onto one end of the outer side of the main housing and is connected to the precision grinding shaft. The bottom of the main body of one set of telescopic electric cylinders is fixed with an electric cylinder connecting seat. Both sides of the main body of the electric cylinder connecting seat are screwed with transmission connecting shafts. The inner end of each set of transmission connecting shafts is fixed with a transmission connecting gear. The transmission connecting toothed pulley is inserted and fixed to the outer end of the transmission connecting shaft. The transmission connecting toothed belt is sleeved and installed between the transmission connecting toothed pulleys.

[0010] The process of using the technical solution of the present invention is as follows:

[0011] The material discharge hopper has a funnel-shaped structure. When the top cover is open, the central gear cannot form an effective transmission connection with the transmission gear. Under the elastic support of the reset slide rod itself, the sliding contact between the reset slide column and the material discharge swing linkage can drive the top opening of the material discharge hopper to tilt towards the top of the main shell, thus facilitating the addition of corn starch slurry into the material discharge hopper.

[0012] During the process of adding starch slurry, a small amount of starch slurry is allowed to enter the inner cavity of the main shell through the narrow channel in the middle of the feeding funnel and the through hole of the primary grinding cover. At this time, the fine grinding teeth are in a high-speed rotating state, which can be used for grinding.

[0013] After the starch slurry is added, the top cover automatically closes. As the top cover closes, the solid rotating seat and the primary grinding cover form a closed inner cavity. During the closing process of the top cover driven by the telescopic electric cylinder, the telescopic electric cylinder body rotates, which in turn drives the electric cylinder connecting seat to rotate. After the top cover closes, one set of transmission connecting gears meshes with the transmission gear, and simultaneously, another set of transmission connecting gears meshes with the central gear. This ensures that the transmission gear can only form an effective transmission connection with the central gear after the top cover closes. At this time, the fine grinding shaft can drive the fine grinding teeth to rotate for fine grinding, and also drive the transmission gear to rotate. The transmission gear, through the engagement with the transmission connecting gear, can drive the rotation of another set of transmission connecting gears through the engagement of the transmission connecting toothed pulley and the transmission connecting toothed belt, causing the central gear to rotate slowly. This provides power for the sliding engagement between the eccentric column and the material dropping swing connecting rod.

[0014] The transmission mechanism can drive the rotation of the central gear. The sliding connection between the eccentric end of the central gear and the material dropping swing link allows the material dropping swing link to overcome the elastic thrust of the reset slide bar and swing back and forth within a certain range, thereby driving the material dropping funnel to swing back and forth.

[0015] The reciprocating oscillation of the feeding funnel can not only make the starch slurry contained in the feeding funnel leak out of the hole at the bottom of the feeding funnel at a uniform and slow speed, but also make the moving grinding seat and the fixed grinding seat fixed inside the bottom of the primary grinding cover form a primary grinding action.

[0016] After primary grinding, the starch slurry can enter the coverage area of ​​the fine grinding teeth in the inner cavity of the main shell through the through hole on the bottom surface of the primary grinding cover, and then be finely crushed and ground by the fine grinding teeth.

[0017] By adopting the above technical solution, the present invention can achieve the following beneficial effects:

[0018] (1) Based on the primary grinding cover fixed at the upper end of the main shell, the present invention divides the inner cavity of the main shell into two parts: a primary grinding cavity and a fine grinding cavity. A material discharge funnel is spun horizontally inside the primary grinding cover to hold the corn starch slurry to be ground. A material discharge swinging link is fixed at the outer end of the rotating shaft of the material discharge funnel. Not only is the eccentric end of the central gear slidably connected to the material discharge swinging link, but the reset sliding column fixed inside the reset sliding rod in the elastic sliding support state is also slidably connected to the material discharge swinging link. The purpose is to make the upper opening of the material discharge funnel tilted towards the top opening of the main shell when the central gear is in a free rotation state, so as to conveniently and safely add corn starch slurry into the material discharge funnel.

[0019] (2) The opening and closing action of the top cover body is not only to cooperate with the main shell to form a closed cavity, but also to enable the transmission gear and the center gear to form an effective transmission connection after the top cover body is closed. Since the transmission gear is connected to the fine grinding shaft, the fine grinding shaft can rotate and drive the fine grinding gear to rotate at the same time, and drive the center gear to rotate synchronously. This allows the eccentric end of the center gear to form a sliding connection with the material dropping swing linkage, driving the material dropping swing linkage to swing back and forth. The material dropping swing linkage drives the material dropping funnel to form a reciprocating swing action, which not only allows the corn starch slurry in the material dropping funnel to enter the inner cavity of the primary grinding cover at a uniform speed, but also drives the moving grinding seat and the solid grinding seat to form a grinding action. Thus, through the synchronous double grinding action, the purpose of fine grinding of corn starch can be achieved. Attached Figure Description

[0036] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0038] like Figures 1-13 The invention relates to a refining and grinding equipment for corn starch production. The top cover 201 is screwed onto the top opening of the main housing 102. Electric cylinder bases 204 are fixed on both outer sides of the main housing 102. Electric cylinder moving bases 205 are fixed on both outer sides of the top cover 201. The bottom body of the telescopic electric cylinder 206 is rotatably connected to the electric cylinder base 204. The top end of the telescopic rod of the telescopic electric cylinder 206 is rotatably connected to the electric cylinder moving base 205.

[0039] Driven by two sets of telescopic electric cylinders 206, the top cover 201 can be opened and closed stably.

[0040] A fine grinding shaft 302 is horizontally screwed onto the lower inner end of the main housing 102. Fine grinding teeth 303 are arranged and fixed on the outside of the fine grinding shaft 302. A primary grinding cover 401 is fixed to the upper inner end of the main housing 102. A discharge funnel 406 is horizontally screwed into the primary grinding cover 401. A fixed grinding seat 403 is arranged and fixed on the inner bottom surface of the primary grinding cover 401. A movable grinding seat 419 is arranged and fixed on the outer bottom surface of the discharge funnel 406. Adjacent movable grinding seats 419 can form a grinding action with the fixed grinding seat 403. A central gear 409 is screwed onto the middle of the outer side of the main housing 102. The discharge funnel 406... The outer end of the rotating shaft is fixed with a material dropping swing connecting rod 411. The eccentric end of the central gear 409 is slidably connected to the material dropping swing connecting rod 411. The outer side of the main housing 102 is also inclinedly elastically slidable with a reset sliding rod 414. The reset sliding rod 414 is slidably connected to the material dropping swing connecting rod 411 through a reset sliding column 417. Under the action of the reset sliding rod 414's own elastic thrust, when there is no external force pushing, the top of the material dropping funnel 406 can be inclined towards one side of the main housing 102, which makes it convenient to add the corn starch slurry to be ground into the material dropping funnel 406 when the top cover 201 is open.

[0041] The transmission gear 607 is screwed onto one end of the outer side of the main housing 102 and is connected to the precision grinding shaft 302. The bottom of the main body of one set of telescopic electric cylinders 206 is fixed with an electric cylinder connecting seat 608. Both sides of the main body of the electric cylinder connecting seat 608 are screwed with transmission connecting shafts 609. The inner end of each set of transmission connecting shafts 609 is fixed with a transmission connecting gear 610. The transmission connecting toothed pulley 611 is inserted and fixed to the outer end of the transmission connecting shaft 609. The transmission connecting toothed belt 612 is sleeved and installed between the transmission connecting toothed pulleys 611.

[0042] The working principle is as follows:

[0043] Before the equipment starts grinding, the top cover 201 must be opened and the rotary drive mechanism connected to the grinding shaft 302 must be started so that the grinding teeth 303 are in a high-speed working state.

[0044] The material discharge hopper 406 has a funnel-shaped structure. When the top cover 201 is open, the central gear 409 cannot form an effective transmission connection with the transmission gear 607. Under the elastic support of the reset slide rod 414, the top opening of the material discharge hopper 406 can be tilted towards the top of the main housing 102 through the sliding engagement between the reset slide rod 417 and the material discharge swing connecting rod 411, thereby facilitating the addition of corn starch slurry into the material discharge hopper 406.

[0045] Furthermore, since the middle part of the discharge funnel 406 is a narrow channel, the added corn starch slurry can accumulate in the upper part of the discharge funnel 406.

[0046] During the process of adding starch slurry, a small amount of starch slurry is allowed to enter the inner cavity of the main housing 102 through the narrow channel in the middle of the discharge funnel 406 and the through hole of the primary grinding cover 401. At this time, the fine grinding teeth 303 are in a high-speed rotating state and can be used for grinding.

[0047] After the starch slurry is added, the top cover 201 automatically closes. As the top cover 201 closes, the fixed base 202 and the initial grinding cover 401 form a closed inner cavity. During the closing process of the top cover 201 driven by the telescopic electric cylinder 206, the main body of the telescopic electric cylinder 206 rotates, thereby driving the rotation of the electric cylinder connecting seat 608. After the top cover 201 is closed, one set of transmission connecting gears 610 meshes with the transmission gear 607, and simultaneously, the other set of transmission connecting gears 610 meshes with the central gear 409. This allows the top cover 201 to close automatically. After the gear is closed, the transmission gear 607 can form an effective transmission connection with the center gear 409. At this time, the fine grinding shaft 302 can drive the fine grinding gear 303 to rotate and perform fine grinding. On the other hand, it can drive the transmission gear 607 to rotate. The transmission gear 607 can drive the rotation of another set of transmission gears 610 through the cooperation between the transmission connecting gear 610 and the transmission connecting belt 612. This will make the center gear 409 rotate slowly, thus providing power for the sliding cooperation between the eccentric column 410 and the blanking swing connecting rod 411.

[0048] The transmission mechanism can drive the rotation of the central gear 409. The sliding connection between the eccentric end of the central gear 409 and the material dropping swing link 411 allows the material dropping swing link 411 to overcome the elastic thrust of the reset slide bar 414 and swing back and forth within a certain range, thereby driving the material dropping funnel 406 to swing back and forth.

[0049] The reciprocating oscillation of the discharge funnel 406 can make the starch slurry contained in the discharge funnel 406 leak out of the hole at the bottom of the discharge funnel 406 at a uniform and slow speed, and can also make the moving grinding seat 419 and the fixed grinding seat 403 fixed on the bottom surface of the primary grinding cover 401 form a primary grinding action.

[0050] After primary grinding, the starch slurry can enter the coverage area of ​​the fine grinding teeth 303 in the inner cavity of the main housing 102 through the through hole on the bottom surface of the primary grinding cover 401, and be finely crushed and ground by the fine grinding teeth 303.

[0051] The specific structures of the base frame component 1 and the top cover component 2 are as follows: Figure 2 and Figure 3As shown, the main housing 102 is fixedly connected to one side of the base frame 101, and the discharge hopper 103 is connected to the bottom end of the main housing 102 and communicates with the inner cavity of the main housing 102.

[0052] The discharge hopper 103 has a corner inclined structure, which facilitates the uniform and slow discharge of corn starch after the grinding process is completed.

[0053] The top cover 201 is screwed to the fixed seat 202 on the outer end of the main housing 102 via a movable seat 203 on one side of the outer end;

[0054] The specific structure of the fine grinding component 3 is as follows: Figure 4 As shown, the precision grinding base 301 is coaxially and symmetrically fixedly installed on the bottom of both sides of the main housing 102. The two ends of the precision grinding shaft 302 are respectively rotatably connected in the precision grinding base 301. The precision grinding pulley 305 is inserted and fixed on the outside of one end of the precision grinding shaft 302. The drive motor 306 is installed and fixed on the top of the other side of the base frame 101. The drive pulley 307 is inserted and fixed in the shaft of the drive motor 306. A transmission belt 308 is sleeved between the drive pulley 307 and the precision grinding pulley 305.

[0055] After the drive motor 306 is started, it can drive the drive pulley 307 to rotate, so that the drive pulley 307 drives the precision grinding pulley 305 to rotate through the transmission belt 308, thereby driving the precision grinding shaft 302 and the precision grinding gear 303 to rotate at high speed.

[0056] To improve the stability and safety of the rotation of the precision grinding teeth 303, a number of hollow horizontal connecting columns 304 are uniformly fixed between the array of precision grinding teeth 303 with the precision grinding shaft 302 as the center.

[0057] The specific structure of the primary grinding component 4 is as follows: Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, the bottom surface of the primary grinding cover 401 is provided with primary grinding sieve holes 402, and each row of primary grinding sieve holes 402 and the grinding base 403 are distributed alternately.

[0058] A side bracket 404 is also fixedly connected to the inner top side of the initial grinding cover 401. When the central gear 409 is in a free rotation state, under the elastic support of the reset slide rod 414, when the top opening of the discharge funnel 406 is tilted towards the top side of the main housing 102, it can overlap with the side bracket 404, so that the corn starch slurry to be ground can be added into the discharge funnel 406 more safely.

[0059] The funnel base 405 is symmetrically fixedly installed on the outer side of the top of the main housing 102. The funnel shaft 407 is horizontally fixed on one side of the material discharge funnel 406. The two ends of the funnel shaft 407 are rotatably connected in the funnel base 405. The material discharge swing connecting rod 411 is fixedly connected to the outer side of one end of the funnel shaft 407.

[0060] A central shaft 408 is fixed in the middle of the outer side of the main housing 102. A central gear 409 is rotatably connected in the central shaft 408. An eccentric column 410 is eccentrically fixed on the outer side of the central gear 409. The eccentric column 410 is slidably connected in the material dropping swing connecting rod 411.

[0061] The outer side of the main housing 102 is also fixed with a first reset slide 412 and a second reset slide 413, and the first reset slide 412 and the second reset slide 413 are distributed in pairs. One end of the reset slide rod 414 is slidably connected in the first reset slide 412, and the other end is slidably connected in the second reset slide 413.

[0062] Furthermore, the first reset slide 412 will not interfere with the rotation of the electric cylinder connecting seat 608 and its related mechanisms;

[0063] The sleeve 415 is fitted and fixed to the outer middle of the reset slide 414. A compression spring 416 is also fitted and installed on the outer side of the reset slide 414. One end of the compression spring 416 is fixed to one side of the sleeve 415, and the other end is fixed to one side of the second reset slide 413.

[0064] Under the support of the compression spring 416 on the sleeve 415, the reset slide rod 414 can have an elastic thrust in the direction of the first reset slide block 412. Thus, through the sliding engagement between the reset slide rod 417 and the material dropping swing link 411, the material dropping swing link 411 can be rotated to a position where the top opening of the material dropping funnel 406 is naturally inclined towards the top of the main housing 102.

[0065] The bottom surface of the discharge hopper 406 is provided with discharge holes 418, and the discharge holes 418 and the moving grinding seat 419 are distributed alternately in sequence.

[0066] The solid grinding base 403 has a trapezoidal structure with a smaller top and a larger bottom, and the moving grinding base 419 has a trapezoidal structure with a larger top and a smaller bottom. Both the solid grinding base 403 and the moving grinding base 419 have rough surfaces on their sides for mutual grinding, which facilitates mutual grinding.

[0067] A material-shaking component 5 is also provided at the junction of the main housing 102 and the discharge hopper 103, which can improve the fine grinding quality of the fine grinding teeth 303, so that the fine grinding teeth 303 can fully grind the corn starch slurry that enters between the outer bottom surface of the primary grinding cover 401 and the inner bottom surface of the main housing 102; the specific structure of the material-shaking component 5 is as follows. Figure 9 and Figure 10 As shown, side seats 502 are fixed on both sides of the top of the shaking plate 501, and side rotating seats 503 are fixed on both sides of the inner cavity of the main housing 102. The side rotating seats 503 are coaxial with the fine grinding rotating seat 301. The fine grinding shaft 302 passes through the side rotating seat 503 and forms a rotatable connection with the fine grinding rotating seat 301. The top of the side seat 502 is rotatably connected to the outside of the side rotating seat 503.

[0068] One side of one set of side seats 502 is fixed with a shaking arm 504, and a shaking seat 505 is fixedly installed on one outer side of the main housing 102. A swing shaft 506 is rotatably connected in the shaking seat 505. An external connecting large gear 507 is inserted and fixed to the outer end of the swing shaft 506. The center of the cam 509 is fixed to the inner end of the swing shaft 506. A rotating small gear 508 is also fixed to one end of the fine grinding shaft 302, and the rotating small gear 508 meshes with the external connecting large gear 507.

[0069] The inner side of the cam 509 is eccentrically fixed with a shaking eccentric column 510, which is slidably connected in the shaking swing arm 504.

[0070] While the grinding shaft 302 rotates at high speed, the rotation of the swing shaft 506 is driven by the transmission cooperation formed by the rotating pinion 508 and the externally connected large gear 507, which in turn drives the rotation of the cam 509. This causes the eccentric column 510 and the swing arm 504 to form an eccentric sliding contact, driving the side seat 502 and the shaking plate 501 to swing back and forth within the first range. The sieve holes in the shaking plate 501 allow corn starch particles that meet its aperture size to fall downwards. Corn starch particles that do not meet its aperture size will remain in the inner cavity of the main housing 102 under the swirling state formed by the high-speed rotation of the grinding teeth 303 until they are ground and broken into particles that meet the aperture size of the shaking plate 501. The reciprocating swinging motion of the shaking plate 501 will shake all the ground corn starch particles into the discharge hopper 103.

[0071] The specific structure of safety transmission component 6 is as follows: Figure 11 and Figure 12 As shown, the outer support base 601 is fixedly connected to the top of the base frame 101, and the swing shaft 506 is rotatably connected in the outer support base 601. The rotational cooperation of the swing shaft 506 formed by the outer support base 601 and the shaking swing base 505 can improve the rotational stability of the swing shaft 506.

[0072] A rotating toothed pulley 602 is also inserted and fixed to the outer end of the swing shaft 506. A transmission shaft seat 603 is fixed to one end of the outer side of the main housing 102. The transmission shaft 604 is rotatably connected in the transmission shaft seat 603. The transmission gear 607 is inserted and fixed to the outer end of the transmission shaft 604. A transmission toothed pulley 605 is also fixed in the transmission shaft 604. A toothed belt 606 is sleeved between the transmission toothed pulley 605 and the rotating toothed pulley 602.

[0073] This allows the small rotating gear 508 to engage with the externally connected large gear 507 for transmission, while the externally connected large gear 507 coaxially drives the rotating toothed pulley 602 via the swing shaft 506. The rotating toothed pulley 602 drives the transmission toothed pulley 605 via the toothed belt 606, and the transmission toothed pulley 605 drives the transmission gear 607 via the transmission shaft 604.

[0074] Furthermore, considering that the corn starch granules shaken off by the shaking plate 501 may accumulate inside the discharge hopper 103, the device also has a pushing component 7 installed on the outer bottom surface of the shaking plate 501. The pushing component 7 includes a pushing side seat 701 and a smooth rod 702. The pushing side seats 701 are fixedly connected in pairs to the outer bottom surface of the shaking plate 501, and the smooth rod 702 is arranged and fixed between the two sets of pushing side seats 701. Through the reciprocating swinging motion of the shaking plate 501, the pushing side seats 701 and the smooth rod 702 can form a reciprocating swinging motion inside the discharge hopper 103. The swinging range will not exceed the discharge hopper 103, thereby eliminating the problem of corn starch granules shaken off by the shaking plate 501 accumulating inside the discharge hopper 103.
