Description

Technical Field

[0001] This invention relates to the field of eggshell processing technology, specifically to a highly efficient crushing and separation device and method for eggshells and shell membranes. Background Technology

[0002] In modern industry and agriculture, eggshells, as a common waste product, contain abundant mineral resources such as calcium and phosphorus, and have high utilization value. Effectively separating eggshells from shell membranes and further processing them can not only achieve resource recycling and reduce environmental pollution, but also create certain economic benefits. For example, eggshell powder can be used as a feed additive to supplement the calcium needed by animals; the shell membrane has potential applications in the pharmaceutical and food industries, such as the collagen in the shell membrane, which can be used to make health products and cosmetics. However, current traditional methods for separating eggshells and shell membranes have many problems. Some simple manual separation methods are extremely inefficient and cannot meet the needs of large-scale production. Furthermore, the separation effect is greatly affected by human factors, making it difficult to guarantee the stability of product quality. Existing crushing and separation equipment generally suffers from incomplete separation. Some equipment relies solely on simple mechanical crushing, which cannot effectively achieve precise separation of eggshells and shell membranes, resulting in a mixture of eggshells and shell membranes in the final product, reducing product purity and application value. In addition, existing equipment often struggles to accurately control the feed rate of eggshells, leading to eggshell accumulation or blockage when conveying eggshells to the separation tank. Therefore, those skilled in the art provide a highly efficient crushing and separation device and method for eggshells and shell membranes to solve the problems mentioned in the background art. Summary of the Invention

[0003] The purpose of this invention is to provide an efficient crushing and separation device and method for eggshells and shell membranes, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: An efficient crushing and separation device and method for eggshells and shell membranes includes a base, an eggshell membrane collection tank, a first rotating rod, a separation tank, a separation mechanism, and a feeding mechanism. The separation tank is mounted on the base, and the eggshell membrane collection tank is mounted on the upper side of the separation tank. The separation mechanism is mounted inside the separation tank on the base. The separation mechanism includes a bearing seat and a separation cylinder. The first rotating rod is fixedly connected to both sides of the separation cylinder, and the bearing seats are symmetrically arranged inside the separation tank. The first rotating rod is located on the bearing seats. The feeding mechanism is mounted on one side of the separation tank and can feed eggshells into the separation cylinder of the separation mechanism.

[0005] As a further embodiment of the present invention: the separation mechanism includes a drive motor, a first synchronous pulley, a transmission frame, a second synchronous pulley, a synchronous belt, a bearing seat, a separation cylinder, auger blades, and a separation groove. The separation cylinder is fixedly connected to the side of the first rotating rod away from the bearing seat. A separation groove is opened inside the separation cylinder. An auger blade is movably connected inside the separation groove. A transmission frame is fixedly connected to one side of the separation cylinder. The second synchronous pulley is fixedly connected to the auger blade inside the transmission frame. The drive motor is fixedly connected to one side of the transmission frame on the base. The first synchronous pulley is fixedly connected to the output end of the drive motor.

[0006] As a further embodiment of the present invention: a synchronous belt is sleeved between the first synchronous pulley and the second synchronous pulley, and the surface of the separating cylinder has a filter screen structure with a mesh diameter of 3-8 mm.

[0007] As a further embodiment of the present invention: the feeding mechanism includes a control frame, a fixed frame, a knob, a sleeve, a third bevel gear, a movable rod, a fourth bevel gear, a fixed plate, a rotating shaft, an incomplete gear, a second rotating rod, a drive rod, a drive wheel, a limit block, and a control baffle. The control frame is fixedly connected to one side of the separation tank, and the fixed frame is fixedly connected inside the control frame. Fixed plates are symmetrically arranged inside the fixed frame, and a rotating shaft is arranged in a ring between the fixed plates. A sleeve is movably connected to one side of the fixed frame, and a movable rod is provided on the sleeve. A third bevel gear is fixedly connected to one end of the movable rod, and a drive rod is movably connected to the side of the fixed plate near the third bevel gear. A fourth bevel gear is fixedly connected to the upper end of the drive rod. The third bevel gear and the fourth bevel gear mesh with each other, and a knob is provided on the side of the third bevel gear that passes through the sleeve.

[0008] As a further embodiment of the present invention: on the side of the fixed plate near the third bevel gear, there are incomplete gears on the rotating shaft, and a control baffle is fixedly connected to the side of each incomplete gear. A limit block is provided on the side between the fixed plate and the control frame. The limit block and the control baffle cooperate with each other. A drive wheel is provided on the side of the drive rod near the incomplete gear. The drive wheel meshes with the incomplete gear.

[0009] As a further embodiment of the present invention: a turbulence motor is embedded below the measuring frame, and a second rotating rod is fixedly connected to the output end of the turbulence motor. The upper end of the second rotating rod is movably connected to a limiting rotating shaft in the fixed plate. A gear groove is opened on the lower surface of the limiting rotating shaft, and a rotating wheel is provided on the rotating shaft on the side of the fixed plate away from the third bevel gear. Each rotating wheel is provided with a turbulence-inducing component. The rotating wheel and the gear groove cooperate with each other, and a feed hopper is provided on one side of the measuring frame.

[0010] As a further embodiment of the present invention: an eggshell collection groove is provided in the base, and a fan is provided on one side of the eggshell collection groove, and a chip discharge port is provided on the side of the eggshell collection groove away from the fan.

[0011] A method for efficiently crushing and separating eggshells and shell membranes includes the following steps: S1: According to the required eggshell feed amount, the operator turns the knob to drive the control baffle to periodically change the opening and closing degree, accurately controlling the number of eggshells entering the separation tank from the feed hopper. At the same time, the limit shaft at the upper end of the second rotating rod drives the rotating wheel to rotate, so that the turbulence component generates a turbulence effect on the eggshells, ensuring that the eggshells enter the separation tank evenly and stably. S2: The eggshells entering the separation tank are agitated by the high-speed rotating auger blades. The auger's stirring teeth continuously agitate the eggshells, causing the eggshell membrane to initially separate from the eggshell and propelling the eggshells forward within the separation tank. S3: As the coarsely crushed eggshells move forward in the separation cylinder, the coarsely crushed eggshells that meet the mesh size of the filter screen fall into the lower eggshell collection section. The eggshells that fall into the lower layer fall into the eggshell collection trough and enter the subsequent processing process through the chip discharge port to be made into eggshell powder. S4: Positive pressure air blows upwards through the filter screen to prevent the eggshell membrane from falling through the sieve holes and mixing into the collected eggshells. It further lifts the lighter eggshell membrane into the eggshell membrane collection tank, promoting a more thorough separation between the eggshell and the eggshell membrane. The blown-out eggshell membrane is collected in time for further processing.

[0012] Compared with the prior art, the beneficial effects of the present invention are: 1. When the operator starts the drive motor, the output of the drive motor quickly drives the first synchronous pulley, which is fixedly connected to it, to start rotating at high speed. Under the stable transmission of the synchronous belt, the second synchronous pulley also rotates quickly, thereby driving the auger blades to make continuous rotational motion in the separation tank. The rotation of the auger blades plays a crucial dual role in the entire separation process. The eggshells that are accurately fed into the separation tank of the separation cylinder from the feeding mechanism will be subjected to a strong squeezing force as soon as they come into contact with the rotating auger blades. Under the combined action of the special shape design and high-speed rotation of the auger blades, the eggshells are effectively crushed into smaller particles. This crushing process greatly increases the possibility of separation between the eggshell and the shell membrane, so that the originally tightly connected eggshell and shell membrane gradually separate. At the same time, the rotation of the auger blades will also generate a stable axial thrust, which will transport the crushed eggshell particles forward in an orderly manner along the separation tank. In this process, the material moves continuously in the separation cylinder, ensuring the continuity and efficiency of the entire separation process. 2. The surface of the separator cylinder adopts a unique filter structure. The mesh diameter of the filter is carefully designed and controlled between 3-8 mm. During the process of crushing and conveying the eggshells by the auger blades, the shell membrane is relatively soft and tough. The crushed shell membrane can pass smoothly through the filter mesh on the surface of the separator cylinder. These shell membrane particles that pass through the filter mesh enter the surrounding space from the inside of the separator cylinder. At this time, the airflow generated by the blower 7 moves upward through the bottom guide channel of the separator tank 4, forming a stable positive pressure airflow field. When the airflow passes through the filter of the separator cylinder 507, it only acts on the eggshell membrane particles, while the coarse eggshells fall directly into the eggshell collection tank 8 below due to gravity and the obstruction of the filter. 3. When the operator rotates the knob, the knob drives the third bevel gear connected to it to rotate. The rotation of the third bevel gear drives the fourth bevel gear to rotate. When the fourth bevel gear rotates, it drives the drive rod to rotate around its own movable connection point. The rotation of the drive rod drives the incomplete gear to rotate through the drive wheel, causing the control baffle to rotate around the rotating shaft. At the same time, the limit block set on one side between the fixed plate and the control frame will limit the rotation range of the control baffle, ensuring that the control baffle rotates within a reasonable angle range. By rotating the knob, the operator can adjust the opening and closing angle of the control baffle, thereby controlling the amount of eggshells entering the separation mechanism from the feed hopper. 4. After the turbulence motor starts, its output end drives the second rotating rod, which is fixedly connected to it, to rotate, which in turn drives the limit shaft to rotate. The lower surface of the limit shaft is provided with a gear groove. The rotating wheel on the shaft on the side of the fixed plate away from the third bevel gear cooperates with the gear groove. The rotation of the limit shaft drives the rotating wheel to rotate around the shaft through the gear groove. The rotation of the rotating wheel causes the turbulence component to rotate accordingly. The turbulence component stirs and agitates the eggshells in the feed hopper, breaking up the possible accumulation and bridging between the eggshells, preventing the eggshells from clogging during the feeding process, and ensuring that the eggshells can continuously and smoothly enter the separation mechanism.

[0024] 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, and 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.

[0025] Example 1

[0026] Reference Figures 1-4This embodiment provides an efficient crushing and separation device for eggshells and shell membranes, including a base 1, an eggshell membrane collection tank 2, a first rotating rod 3, a separation tank 4, a separation mechanism 5, and a feeding mechanism 6. The separation tank 4 is provided on the base 1, and the eggshell membrane collection tank 2 is provided on the upper side of the separation tank 4. The separation mechanism 5 is provided inside the separation tank 4 in the base 1. The separation mechanism 5 includes a bearing seat 506 and a separation cylinder 507. The first rotating rod 3 is fixedly connected to both sides of the separation cylinder 507, and the bearing seats 506 are symmetrically arranged inside the separation tank 4. The first rotating rod 3 is located on the bearing seats 506. The feeding mechanism 6 is provided on one side of the separation tank 4. The feeding mechanism 6 can feed eggshells into the separation cylinder 507 of the separation mechanism 5. An eggshell collection groove 8 is opened in the base 1, and a fan 7 is provided on one side of the eggshell collection groove 8 in the base 1. A chip discharge port 9 is opened on the side of the eggshell collection groove 8 away from the fan 7. In this embodiment, specifically, the separation mechanism 5 includes a drive motor 501, a first synchronous pulley 502, a transmission frame 503, a second synchronous pulley 504, a synchronous belt 505, a bearing seat 506, a separation cylinder 507, a auger blade 508, and a separation groove 509. The first rotating rod 3 is fixedly connected to the separation cylinder 507 on the side away from the bearing seat 506. A separation groove 509 is opened in the separation cylinder 507. An auger blade 508 is movably connected in the separation groove 509. A transmission frame 503 is fixedly connected to one side of the separation cylinder 507. The second synchronous pulley 504 is fixedly connected to the auger blade 508 in the transmission frame 503. The drive motor 501 is fixedly connected to one side of the transmission frame 503 and the base 1. The output end of the drive motor 501 is fixedly connected to the first synchronous pulley 502. A timing belt 505 is sleeved between the first timing pulley 502 and the second timing pulley 504, and the surface of the separating cylinder 507 is a filter screen structure with a mesh diameter of 3-8 mm. When the operator starts the drive motor 501, the output of the drive motor 501 quickly drives the first synchronous pulley 502, which is fixedly connected to it, to start rotating at high speed. Under the stable transmission action of the synchronous belt 505, the second synchronous pulley 504 also rotates rapidly, thereby driving the auger blades 508 to rotate continuously in the separation tank 509. The rotation of the auger blades 508 plays a crucial dual role in the entire separation process. Eggshells accurately fed into the separation tank 509 of the separation cylinder 507 from the feeding mechanism 6, once in contact with the rotating auger blades 508, will immediately be subjected to a strong squeezing action. Under the combined action of the special shape design and high-speed rotation of the auger blades 508, the eggshells are effectively broken into smaller particles. This crushing process greatly increases the possibility of separation between the eggshell and the shell membrane, causing the originally tightly connected eggshell and shell membrane to gradually separate. At the same time, the rotation of the auger blades 508 also generates a A stable axial thrust transports the crushed eggshell particles forward in an orderly manner along the separation tank 509. During this process, the material moves continuously within the separation cylinder 507, ensuring the continuity and efficiency of the entire separation process. The surface of the separation cylinder 507 adopts a unique filter screen structure. The mesh diameter of the filter screen is carefully designed and controlled between 3-8 mm. During the crushing and conveying of the eggshells by the auger blades 508, due to the relatively soft and tough texture of the shell membrane, the crushed shell membrane can pass smoothly through the filter screen holes on the surface of the separation cylinder 507. These shell membrane particles that pass through the filter screen holes enter the surrounding space from inside the separation cylinder 507. At this time, the airflow generated by the blower 7 moves upward through the bottom guide channel of the separation tank 4, forming a stable positive pressure airflow field. When this airflow passes through the filter screen of the separation cylinder 507, it only acts on the eggshell membrane particles, while the coarsely crushed eggshells fall directly into the eggshell collection tank 8 below due to gravity and the obstruction of the filter screen.

[0028] Reference Figures 5-10This embodiment is based on the previous embodiment, but differs in that the feeding mechanism 6 includes a control frame 601, a fixed frame 602, a knob 603, a sleeve 605, a third bevel gear 606, a movable rod 607, a fourth bevel gear 608, a fixed plate 609, a rotating shaft 610, an incomplete gear 611, a second rotating rod 612, a drive rod 613, a drive wheel 614, a limiting block 615, and a control baffle 616. The control frame 601 is fixedly connected to one side of the separation tank 4, and the fixed frame 602 is fixedly connected inside the control frame 601. A fixing plate 609 is symmetrically arranged, and a rotating shaft 610 is arranged in a ring between the fixing plates 609. A sleeve 605 is movably connected to one side of the fixing frame 602. A movable rod 607 is arranged on the sleeve 605. A third bevel gear 606 is fixedly connected to one end of the movable rod 607. A drive rod 613 is movably connected to the side of the fixing plate 609 near the third bevel gear 606. A fourth bevel gear 608 is fixedly connected to the upper end of the drive rod 613. The third bevel gear 606 and the fourth bevel gear 608 mesh with each other. A knob 603 is arranged on one side of the third bevel gear 606 that passes through the sleeve 605. On the side of the fixed plate 609 near the third bevel gear 606, there are incomplete gears 611 on the rotating shaft 610. A control baffle 616 is fixedly connected to one side of each incomplete gear 611. A limit block 615 is provided on one side between the fixed plate 609 and the control frame 601. The limit block 615 and the control baffle 616 cooperate with each other. A drive wheel 614 is provided on the side of the drive rod 613 near the incomplete gear. The drive wheel 614 meshes with the incomplete gear 611. A turbulence motor 620 is embedded below the control frame 601. The output end of the turbulence motor 620 is fixedly connected to a second rotating rod 612. The upper end of the second rotating rod 612 is movably connected to a limiting shaft 617 within a fixed plate 609. A gear groove is provided on the lower surface of the limiting shaft 617. A rotating wheel 618 is provided on the rotating shaft 610 on the side of the fixed plate 609 away from the third bevel gear 606. Each rotating wheel 618 is provided with a turbulence element 619. The rotating wheel 618 and the gear groove cooperate with each other. A feed hopper 604 is provided on one side of the control frame 601. When the operator rotates knob 603, knob 603 drives the connected third bevel gear 606 to rotate. The rotation of the third bevel gear 606 drives the fourth bevel gear 608 to rotate. When the fourth bevel gear 608 rotates, it drives the drive rod 613 to rotate around its own movable connection point. The rotation of the drive rod 613 drives the incomplete gear 611 to rotate through the drive wheel 614, causing the control baffle 616 to rotate around the rotating shaft 610. At the same time, the limiting block 615 set on one side between the fixed plate 609 and the control frame 601 restricts the rotation range of the control baffle 616, ensuring that the control baffle 616 rotates within a reasonable angle range. By rotating knob 603, the operator can adjust the opening and closing angle of the control baffle 616, thereby controlling the amount of eggshells entering the separation mechanism from the feed hopper 604. After the turbulence motor 620 starts, its output end drives the second rotating rod 612, which is fixedly connected to it, to rotate, which in turn drives the limiting shaft 617 to rotate. The lower surface of the limiting shaft 617 is provided with a gear groove. The rotating wheel 618 on the rotating shaft 610 on the side of the fixed plate 609 away from the third bevel gear 606 cooperates with the gear groove. The rotation of the limiting shaft 617 drives the rotating wheel 618 to rotate around the rotating shaft 610 through the gear groove. The rotation of the rotating wheel 618 causes the turbulence member 619 to rotate accordingly. The turbulence member 619 stirs and agitates the eggshells in the feed bin 604, breaking up the possible accumulation and bridging between the eggshells, preventing the eggshells from clogging during the feeding process, and ensuring that the eggshells can continuously and smoothly enter the separation mechanism 5.

[0029] Example 3

[0030] A method for efficiently crushing and separating eggshells and shell membranes includes the following steps: S1: According to the required eggshell feed amount, the operator turns the knob 603, which drives the control baffle 616 to periodically change the opening and closing degree, and precisely controls the amount of eggshells entering the separation tank 4 from the feed hopper 604. At the same time, the limit shaft 617 at the upper end of the second rotating rod 612 drives the rotating wheel 618 to rotate, so that the turbulence component 619 generates a turbulence effect on the eggshells, ensuring that the eggshells enter the separation tank 4 evenly and stably. S2: The eggshells entering the separation tank 4 are agitated by the high-speed rotating auger blades 508. The auger's stirring teeth continuously agitate the eggshells, causing the eggshell membrane to initially separate from the eggshell and pushing the eggshells forward in the separation cylinder 507. S3: During the process of the coarsely crushed eggshells moving forward in the separation cylinder 507, the coarsely crushed eggshells that meet the mesh size of the filter screen fall into the lower eggshell collection section through the filter screen. The eggshells that fall into the lower layer fall into the eggshell collection trough 8 and enter the subsequent processing process through the chip discharge port 9 to be made into eggshell powder. S4: Positive pressure air blows upwards through the filter screen to prevent the eggshell membrane from falling through the sieve holes and mixing into the collected eggshells. It further lifts the lighter eggshell membrane into the eggshell membrane collection tank 2, promoting a more thorough separation between the eggshell and the eggshell membrane. The blown-out eggshell membrane is collected in time for further processing.

The upper end of the second rotating rod (612) is movably connected to a limiting shaft (617) in a fixed plate (609). A gear groove is provided on the lower surface of the limiting shaft (617). A rotating wheel (618) is provided on the rotating shaft (610) on the side of the fixed plate (609) away from the third bevel gear (606). A turbulence element (619) is provided on each of the rotating wheels (618). The rotating wheels (618) and the gear groove cooperate with each other. A feed hopper (604) is provided on one side of the measuring frame (601).

7. The high-efficiency crushing and separating device for eggshells and shell membranes according to claim 1, characterized in that, The base (1) has an eggshell collection trough (8) and a fan (7) is provided on one side of the eggshell collection trough (8). A chip discharge port (9) is provided on the side of the eggshell collection trough (8) away from the fan (7).

8. A method for using the high-efficiency crushing and separating device for eggshells and shell membranes as described in any one of claims 1-7, characterized in that, Includes the following steps: S1: According to the required eggshell feed amount, the operator turns the knob (603) to drive the control baffle (616) to periodically change the opening and closing degree, and accurately control the amount of eggshells entering the separation tank (4) from the feed hopper (604). At the same time, the limit shaft (617) at the upper end of the second rotating rod (612) drives the rotating wheel (618) to rotate, so that the turbulence component (619) generates a turbulence effect on the eggshells, ensuring that the eggshells enter the separation tank (4) evenly and stably. S2: The eggshells entering the separation tank (4) are agitated by the high-speed rotating auger blades (508). The auger's stirring teeth continuously agitate the eggshells, causing the eggshell membrane to initially separate from the eggshell and pushing the eggshells forward in the separation cylinder (507). S3: During the process of the coarsely crushed eggshells moving forward in the separation cylinder (507), the coarsely crushed eggshells that meet the mesh size of the filter screen fall into the lower eggshell collection section through the filter screen. The eggshells that fall into the lower layer fall into the eggshell collection trough (8) and enter the subsequent processing process through the chip discharge port (9) to be made into eggshell powder. S4: Positive pressure air blows upward through the filter screen to prevent the eggshell membrane from falling through the sieve holes and mixing into the collected eggshells. It further lifts the lighter eggshell membrane into the eggshell membrane collection tank (2), promoting a more thorough separation between the eggshell and the eggshell membrane. The blown-out eggshell membrane is collected in time for further processing.
