Description

Technical Field

[0001] This utility model relates to the field of acorn processing technology, specifically to a pulp-residue separation device for acorn processing. Background Technology

[0002] In acorn processing, pulp-residue separation is a crucial step in separating the solid residue from the liquid pulp after crushing acorn pulp. This directly affects the efficiency of subsequent starch extraction and the purity of the product. The purpose is to separate the starch milk from the acorn pulp and remove insoluble residues such as cellulose, hemicellulose, lignin, and residual seed coats, providing pure raw materials for subsequent starch purification and drying. Pulp-residue separation utilizes the differences in particle size, density, or flowability between the residue and the starch milk to achieve separation through methods such as sieving, centrifugation, and sedimentation, thereby reducing starch residue in the residue and improving raw material utilization.

[0003] In existing technologies, centrifugal devices are used to separate the pulp and residue produced during acorn processing. The pulp is thrown out by centrifugal force and collected in an inner cylinder. The pulp flows through the gap between the centrifugal cylinder and the inner cylinder to the discharge port, while the residue is retained inside the centrifugal cylinder. After processing a certain amount of acorns, the machine needs to be stopped to clean the residue. Moreover, cleaning the residue requires workers to use tools to disassemble the centrifugal cylinder, resulting in a long downtime. Therefore, a pulp and residue separation device for acorn processing is proposed to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a pulp-residue separation device for acorn processing, which has the advantages of short downtime and easy cleaning. It solves the problem that residue is retained inside the centrifuge drum, requiring the machine to be stopped and cleaned after processing a certain amount of acorns. Moreover, cleaning the residue requires workers to disassemble the centrifuge drum with tools, resulting in a long downtime.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pulp-residue separation device for acorn processing, comprising a pulp-residue separation device, an inner cylinder and a centrifuge cylinder, wherein the bottom of the centrifuge cylinder is provided with an automatic locking structure;

[0006] The automatic locking structure includes a protective cylinder installed inside the slurry-sludge separation device. A servo motor is fixedly installed inside the protective cylinder. A turntable is fixedly connected to the output end of the servo motor. A docking plate for connecting a centrifuge cylinder is provided on the top of the turntable. A positioning plate for positioning the turntable and the docking plate is provided on the bottom of the turntable. A connecting positioning component is fixedly installed on the bottom of the centrifuge cylinder. Four positioning components for fixing the positioning component are provided on the docking plate.

[0007] The turntable has four arc-shaped grooves that are slidably connected to the positioning element, the docking plate has four guide grooves that are slidably connected to the positioning element, and the docking plate has a docking groove that is adapted to the connector.

[0008] Furthermore, the positioning disk also includes four positioning posts with one end penetrating through the docking disk and the turntable. An annular slide rail is fixedly installed at the bottom of the positioning disk. Two sliders are slidably installed inside the annular slide rail. The protective cylinder is provided with two electric push rods with telescopic ends fixedly connected to the two sliders respectively. The positioning disk is slidably installed on the turntable.

[0009] Furthermore, a motor frame and two side frames are fixedly installed inside the protective cylinder. The two side frames are respectively fixedly connected to two electric push rods, and the motor frame is fixedly connected to a servo motor.

[0010] Furthermore, each of the four positioning components has a positioning groove, which is adapted to the arc end of the connector, and the opposite side of the four positioning components is in close contact with the four top sides of the connector.

[0011] Furthermore, both the docking plate and the turntable have four locking holes inside, and the locking holes are symmetrically distributed around the axis of the turntable. The size of the locking holes is adapted to the size of the positioning pin.

[0012] Furthermore, the size of the turntable is adapted to the larger end size of the protective cylinder, and the turntable is rotatably installed inside the protective cylinder, wherein the larger end size of the protective cylinder is adapted to the diameter of the centrifuge cylinder.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0014] This pulp-residue separation device for acorn processing features an automatic locking structure. It utilizes an electric push rod linked to a servo motor as the drive source to control the unlocking and locking of the docking plate and turntable, and uses positioning components to fix the connecting parts. This transforms the mechanical locking structure into automated control. Combined with a quick-install centrifuge tube design, it shortens the time required for centrifuge tube disassembly and installation, further reducing downtime. This solves the problems of "difficult cleaning and long downtime" in pulp-residue separation equipment during acorn processing. It also reduces the difficulty and labor intensity of manual disassembly. Furthermore, the symmetrical design of the positioning pins of the positioning plate with the locking holes of the docking plate and turntable ensures positioning accuracy and structural stability, reducing vibration and impact during centrifugation and minimizing component wear.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1: Please refer to Figure 1-8 The pulp and residue separation device for acorn processing in this embodiment includes a pulp and residue separation device 1, an inner cylinder 2 and a centrifuge cylinder 3, and an automatic locking structure 4 is provided at the bottom of the centrifuge cylinder 3.

[0026] Example 2: Please refer to Figure 1-8Based on Embodiment 1, the automatic locking structure 4 includes a protective cylinder 41 installed inside the slurry-sludge separation device 1. A servo motor 42 is fixedly installed inside the protective cylinder 41. A turntable 43 is fixedly connected to the output end of the servo motor 42. A docking plate 45 for connecting the centrifuge cylinder 3 is provided on the top of the turntable 43. A positioning plate 44 for positioning the turntable 43 and the docking plate 45 is provided on the bottom of the turntable 43. A connector 47 and a positioning piece 46 are fixedly installed on the bottom of the centrifuge cylinder 3. Four positioning pieces 46 for fixing the positioning pieces 46 are provided on the docking plate 45.

[0027] The turntable 43 has four arc-shaped grooves 431 that are slidably connected to the positioning member 46, the docking plate 45 has four guide grooves 451 that are slidably connected to the positioning member 46, and the docking plate 45 has a docking groove 452 that is adapted to the connector 47.

[0028] The four positioning parts 46 are provided with positioning grooves, which are adapted to the arc end of the connecting part 47. The opposite sides of the four positioning parts 46 are in close contact with the top four sides of the connecting part 47. The arc adaptation design of the positioning parts 46 and the connecting part 47 can be compatible with centrifuge cylinders 3 of different specifications. The equipment has strong versatility and is convenient for subsequent production line upgrades.

[0029] In addition, the size of the turntable 43 is adapted to the larger end size of the protective cylinder 41, and the turntable 43 is rotatably installed inside the protective cylinder 41. The larger end size of the protective cylinder 41 is adapted to the diameter of the centrifuge cylinder 3. It can work with the servo motor 42 to control the rotation of the turntable 43 and use the turntable 43 to drive the centrifuge cylinder 3 to rotate. Centrifugal force is used to screen the acorn pulp residue, reduce the pulp seepage into the interior of the protective cylinder 41, and protect the servo motor 42 and the positioning plate 44 inside the protective cylinder 41.

[0030] Using the above technical solution, the centrifuge cylinder 3 is inserted into the docking groove 452 of the docking plate 45 through the bottom connector 47. Four positioning pieces 46 are embedded in the arc-shaped groove 431 of the turntable 43 and the guide groove 451 of the docking plate 45. The positioning groove is tightly fitted with the arc end of the connector 47 to achieve a fixed connection between the centrifuge cylinder 3 and the turntable 43. The positioning plate 44 is locked by four positioning pins 441 through the locking holes of the docking plate 45 and the turntable 43, ensuring structural stability during centrifugation.

[0031] Example 3: Please refer to Figure 1-8 Based on Embodiment 2, the positioning disk 44 also includes four positioning posts 441 with one end penetrating through the docking disk 45 and the turntable 43. An annular slide rail 442 is fixedly installed at the bottom of the positioning disk 44. Two sliders 443 are slidably installed inside the annular slide rail 442. Two electric push rods 444 with telescopic ends fixedly connected to the two sliders 443 are provided on the protective cylinder 41. The positioning disk 44 is slidably installed on the turntable 43.

[0032] The protective cylinder 41 has a motor frame and two side frames fixedly installed inside. The two side frames are fixedly connected to two electric push rods 444 respectively. The motor frame is fixedly connected to the servo motor 42, which facilitates the installation of the servo motor 42 and the electric push rods 444, and at the same time provides protection for the servo motor 42 and the electric push rods 444.

[0033] In addition, four locking holes are provided inside both the docking plate 45 and the turntable 43, and the locking holes are symmetrically distributed around the axis of the turntable 43. The size of the locking holes is adapted to the size of the positioning post 441. The positioning post 441 of the positioning plate 44 is symmetrically designed with the locking holes of the docking plate 45 and the turntable 43. With the smooth sliding of the annular slide rail 442 and the slider 443, the positioning accuracy and structural stability are ensured, the vibration and impact during the centrifugation process are reduced, and the wear of the components is reduced.

[0034] Using the above technical solution, when it is necessary to stop the machine to clean the acorn residue inside the centrifuge tube 3, the telescopic end of the electric push rod 444 on the protective tube 41 pushes the slider 443 to slide in the annular slide rail 442, causing the positioning plate 44 to move downward. The positioning pin 441 on the positioning plate 44 gradually exits the locking hole of the docking plate 45 and the turntable 43, releasing the positioning constraint on the turntable 43 and the docking plate 45. The servo motor 42 starts and drives the turntable 43 to rotate. Since the positioning part 46 slides in the arc groove 431 and the guide groove 451, when the turntable 43 rotates, the positioning part 46 moves along the arc groove 431, gradually loosening the clamping of the connecting part 47. When the positioning part 46 is completely separated from the connecting part 47, the centrifuge tube 3 loses its constraint and can be directly removed from the docking groove 452 of the docking plate 45, completing the disassembly and cleaning of the acorn residue, thereby shortening the time required for disassembly.

[0035] The working principle of the above embodiments is as follows:

[0036] In this pulp and residue separation device for acorn processing, the centrifuge cylinder 3 is inserted into the docking groove 452 of the docking plate 45 through the bottom connector 47. Four positioning pieces 46 are embedded in the arc-shaped groove 431 of the turntable 43 and the guide groove 451 of the docking plate 45. The positioning grooves are tightly fitted with the arc-shaped end of the connector 47 to achieve a fixed connection between the centrifuge cylinder 3 and the turntable 43. The positioning plate 44 is locked by four positioning pins 441 through the locking holes of the docking plate 45 and the turntable 43, ensuring structural stability during centrifugation.

[0037] When it is necessary to stop the machine to clean the acorn residue inside the centrifuge tube 3, the telescopic end of the electric push rod 444 on the protective tube 41 pushes the slider 443 to slide in the annular slide rail 442, which drives the positioning plate 44 to move downward. The positioning pin 441 on the positioning plate 44 gradually exits the locking hole of the docking plate 45 and the turntable 43, releasing the positioning constraint on the turntable 43 and the docking plate 45.

[0038] After the positioning column 441 is completely disengaged, the servo motor 42 starts and drives the turntable 43 to rotate. As the positioning component 46 slides in the arc groove 431 and the guide groove 451, the positioning component 46 moves along the arc groove 431 when the turntable 43 rotates, gradually loosening its clamping on the connector 47. When the positioning component 46 is completely disengaged from the connector 47, the centrifuge cylinder 3 loses its constraint and can be directly removed from the docking groove 452 of the docking plate 45, completing the disassembly and cleaning the acorn residue, thereby shortening the time required for disassembly.
