Description

Technical Field

[0001] This utility model relates to the technical field of starch production equipment, specifically to a centrifugal sand removal device for starch processing. Background Technology

[0002] In starch processing, removing sand and other impurities from raw materials is a crucial step in ensuring product quality. Centrifuges are machines that use centrifugal force to separate components in a mixture of liquids and solid particles or liquids. Centrifuges are primarily used to separate solid particles from the liquid in a suspension; depending on the specific needs, even particles of the same type may require centrifugation. However, traditional centrifugal desanding devices have some limitations: for example, they struggle to effectively separate substances of similar particle size, and the impurities remaining after separation cannot be quickly removed, leading to decreased production efficiency.

[0003] For example, patent application CN220126564U discloses a centrifugal sieve for starch production, including a sleeve, a sieve cylinder, and a support platform. Connecting rods are welded to the four corners of the bottom inner side of the sleeve. A support platform is welded to the center of the bottom inner side of the sleeve via the connecting rods. A rotating seat is fixedly installed on the top shaft of the motor. A bracket is welded to the top of the telescopic rod, and a cover plate is welded to the other end of the bracket, located above the sleeve. This design allows for quick and convenient insertion and removal of the sieve cylinder within the sleeve, facilitating the switching between sieve cylinders with different mesh sizes, and also making it easier to empty residue from the sieve cylinder and clean the sieve cylinder.

[0004] Although the centrifugal sieve for starch production features a detachable sieve cylinder design, which facilitates cleaning and the emptying of residues inside the sieve cylinder, greatly improving its flexibility, the fact that the device requires workers to unplug and plug it in after each use and empty the entire sieve cylinder inside the sleeve not only increases labor intensity but also limits the overall efficiency of the production process.

[0005] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0006] In view of the problems in the related technologies, this utility model proposes a centrifugal sand removal device for starch processing to overcome the above-mentioned technical problems existing in the existing related technologies.

[0007] Therefore, the specific technical solution adopted by this utility model is as follows:

[0008] A centrifugal desanding device for starch processing includes a workbench, a centrifugal tank at the bottom of one side of the workbench, and a lifting mechanism at the top of the other side of the workbench; a cover plate is provided on one side of the lifting mechanism, and a centrifugal mechanism is provided at the bottom of the cover plate and inside the centrifugal tank for desanding starch; a control panel is provided on one side of the workbench, and a feed inlet is provided at the top of the cover plate and inside the centrifugal mechanism; and a discharge pipe is provided at the bottom of the centrifugal tank.

[0009] Furthermore, in order to effectively and efficiently collect the starch after sand removal and further optimize the starch flow path, the bottom of the centrifuge tank is designed with a cone shape for collecting the starch after sand removal.

[0010] Furthermore, in order to reduce the intensity of manual labor and ensure the stability of equipment operation, the lifting mechanism includes several cylinders set on the top of the other side of the workbench. The output end of the cylinder is connected to a mounting plate, and one side of the mounting plate is connected to the cover plate.

[0011] Furthermore, in order to separate impurities such as sand particles, improve sand removal efficiency and accuracy, ensure the purity of the processed material, and enable quick disassembly of the conical sand removal screen for easy cleaning of sand and other impurities, the centrifugal mechanism includes a drive component located in the middle of the bottom of the cover plate, with a driven component fitted on the top of the drive component. The drive component includes a rotating shaft located in the middle of the cover plate, with several circumferentially arranged grooves on the outer wall of the rotating shaft; a cross bracket is engaged at the bottom of the rotating shaft, and a conical sand removal screen is fitted on the outer wall of the cross bracket, with a first ratchet at the top of the conical sand removal screen; a key that mates with the grooves is provided on the inner wall of the cross bracket; the top of the rotating shaft passes through the cover plate and is connected to the output shaft of a servo motor. The driven component includes a circular sand-removing screen disposed on top of the driving component. The inner bottom wall of the circular sand-removing screen has an annular locking groove that mates with the outer wall of the conical sand-removing screen. The inner wall of the annular locking groove has several strip-shaped limiting grooves arranged in a circle. A spring is disposed at the bottom of the annular locking groove. A second ratchet is disposed at the bottom of the spring that mates with the first ratchet. A slider is disposed on the outer wall of the second ratchet that mates with the strip-shaped limiting grooves. An annular limiting block is disposed at the top of the circular sand-removing screen.

[0012] Furthermore, in order to achieve a more thorough separation of starch and impurities under centrifugal force and improve sand removal efficiency and separation accuracy, both the circular and conical sand removal screens have several equidistantly arranged through holes on their side walls, with the three through holes located on two adjacent straight lines being staggered.

[0013] Furthermore, in order to prevent the cover plate from shifting or loosening during equipment operation and to ensure the safety and reliability of the centrifugal mechanism when it is running at high speed, an annular limiting groove is provided at the bottom of the cover plate to cooperate with the annular limiting block.

[0014] Furthermore, in order to allow starch to slide more smoothly into the collection area under the combined action of gravity and centrifugal force, effectively avoiding accumulation or blockage, and ensuring the continuity and stability of the production process, the cone slope of the cone-shaped sand removal mesh is the same as that of the centrifuge tank.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. This utility model has a reasonable and reliable structure and is simple to operate. With the coordinated action of the workbench, centrifuge tank, lifting mechanism, centrifugal mechanism, inlet, and outlet pipe, and under the action of the centrifugal mechanism, starch can be thoroughly desanded after entering the centrifuge tank, thus ensuring desanding efficiency. Furthermore, the lifting mechanism allows the centrifugal mechanism to be precisely separated from the centrifuge tank, ensuring the sealing of the centrifuge tank and facilitating subsequent disassembly and cleaning of the centrifugal mechanism by staff, thereby greatly reducing manual labor and improving desanding efficiency.

[0017] 2. This utility model, through the installation of a lifting mechanism, can accurately separate the centrifuge unit from the centrifuge tank under the combined action of a cylinder and a mounting plate. This not only facilitates subsequent disassembly and cleaning of the centrifuge unit but also significantly reduces manual labor intensity. It ensures the stability and safety of the equipment during operation.

[0018] 3. This utility model, through the setting of a centrifugal mechanism, utilizes the combined action of a rotating shaft, a conical desanding screen, a first ratchet, a groove, a key, a circular desanding screen, an annular locking groove, a spring, and a second ratchet to efficiently remove sand from starch in a centrifuge tank. The design of the conical and circular desanding screens ensures the effective separation of impurities of different particle sizes, while the first and second ratchets provide stable rotational power, guaranteeing smooth operation throughout the desanding process. After the desanding process is completed, the centrifugal mechanism can be precisely separated from the centrifuge tank via a lifting mechanism. The groove and key facilitate quick disassembly and cleaning of the conical desanding screen. This not only simplifies the maintenance process and reduces manual labor intensity but also ensures long-term stable operation of the equipment and efficient desanding results.

[0027] To further illustrate the various embodiments, the present invention provides accompanying drawings, which are part of the disclosure of the present invention. These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0028] According to an embodiment of the present invention, a centrifugal sand removal device for starch processing is provided.

[0029] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figures 1-5As shown, a centrifugal desanding device for starch processing according to an embodiment of the present invention includes a workbench 1, a centrifugal tank 2 is provided at the bottom of one side of the workbench 1, and a lifting mechanism 3 is provided at the top of the other side of the workbench 1; a cover plate 4 is provided on one side of the lifting mechanism 3, and a centrifugal mechanism 5 is provided at the bottom of the cover plate 4 and inside the centrifugal tank 2 for desanding starch; a control panel 6 is provided on one side of the workbench 1, and a feed inlet 7 is provided at the top of the cover plate 4 and inside the centrifugal mechanism 5; and a discharge pipe 8 is provided at the bottom of the centrifugal tank 2.

[0030] With the help of the above technical solution, through the coordinated action of the workbench 1, centrifuge tank 2, lifting mechanism 3, centrifuge mechanism 5, feed inlet 7, and discharge pipe 8, the starch can be thoroughly desanded after entering the centrifuge tank 2 under the action of the centrifuge mechanism 5, thus ensuring the desanding efficiency. Furthermore, the lifting mechanism 3 enables the centrifuge mechanism 5 to be precisely separated from the centrifuge tank 2, ensuring the sealing of the centrifuge tank 2 and facilitating subsequent disassembly and cleaning of the centrifuge mechanism 5 by the staff, thereby greatly reducing manual labor and improving the desanding efficiency.

[0031] It should be noted that in practical applications, the lifting mechanism 3 and the centrifugal mechanism 5 are electrically connected through the control panel 6. This is existing technology and will not be elaborated further.

[0032] In one embodiment, the centrifuge tank 2 has a conical bottom design for collecting the starch after sand removal, which not only effectively and efficiently collects the starch after sand removal, but also further optimizes the flow path of the starch.

[0033] In one embodiment, the lifting mechanism 3 includes several cylinders 301 disposed on the top of the other side of the workbench 1. The output end of the cylinders 301 is connected to a mounting plate 302, and one side of the mounting plate 302 is connected to the cover plate 4, which reduces the intensity of manual labor and ensures the stability of the equipment during operation.

[0034] The specific working principle of the lifting mechanism 3 is as follows: When the cylinder 301 is started, the mounting plate 302 connected to its output end moves up and down, thereby driving the cover plate 4 connected to one side of the mounting plate 302 to rise or fall, thus completing the lifting function of the lifting mechanism 3.

[0035] In one embodiment, the centrifugal mechanism 5 includes a drive member 501 located at the bottom center of the cover plate 4, and a driven member 502 fitted at the top of the drive member 501. The drive member 501 includes a rotating shaft 5011 located at the center of the cover plate 4, with a plurality of circumferentially arranged grooves 5016 on the outer wall of the rotating shaft 5011; a cross bracket 5012 is engaged at the bottom of the rotating shaft 5011, and a conical sand-removing screen 5013 is sleeved on the outer wall of the cross bracket 5012, with a first ratchet 5014 at the top of the conical sand-removing screen 5013; a key 5017 that mates with the grooves 5016 is provided on the inner wall of the cross bracket 5012; and the top of the rotating shaft 5011 passes through the cover plate 4 and is connected to the output shaft of the servo motor 5015. The driven component 502 includes a circular sand-removing screen 5021 disposed on the top of the driving component 501. The inner wall of the bottom of the circular sand-removing screen 5021 has an annular locking groove 5022 that cooperates with the outer wall of the conical sand-removing screen 5013. The inner wall of the annular locking groove 5022 has several strip-shaped limiting grooves 5027 arranged in a circle. A spring 5023 is disposed at the bottom of the annular locking groove 5022. A second ratchet 5024 that cooperates with the first ratchet 5014 is disposed at the bottom of the spring 5023. A slider 5026 that cooperates with the strip-shaped limiting grooves 5027 is disposed on the outer wall of the second ratchet 5024. An annular limiting block 5025 is disposed at the top of the circular sand-removing screen 5021. It can effectively separate sand particles and other impurities, improve the sand removal efficiency and accuracy, and ensure the purity of the processed material. It not only realizes the quick disassembly of the conical sand-removing screen 5013, but also facilitates the cleaning of sand and other impurities.

[0036] The specific working principle of the centrifugal mechanism 5 is as follows: After the servo motor 5015 is started, its output shaft drives the rotating shaft 5011 to rotate. The groove 5016 on the outer wall of the rotating shaft 5011 cooperates with the key 5017 on the inner wall of the cross bracket 5012, so that the cross bracket 5012 can rotate synchronously with the rotating shaft 5011. A conical sand removal screen 5013 is installed on the outer wall of the cross bracket 5012, and the top of the conical sand removal screen 5013 is provided with a first ratchet 5014. The first ratchet 5014 cooperates with the second ratchet 5024 on the circular sand removal screen 5021. The inner wall of the circular sand removal mesh 5021 is provided with a strip-shaped limiting groove 5027, while the outer wall of the second ratchet 5024 is provided with a slider 5026. The two work together to allow the circular sand removal mesh 5021 to rotate synchronously with the conical sand removal mesh 5013. When the rotating shaft 5011 rotates, the first ratchet 5014 meshes with the second ratchet 5024, and the spring 5023 provides elastic force to ensure that the second ratchet 5024 tightly contacts the first ratchet 5014, ensuring the stability of power transmission. The ratchet mechanism allows the conical sand removal mesh 5013 and the circular sand removal mesh 5021 to rotate in a specific direction, preventing reverse rotation and thus achieving unidirectional drive. After sand removal is completed, sand and other impurities are confined within the conical sand removal mesh 5013 and the circular sand removal mesh 5021, and eventually fall into the conical sand removal mesh 5013. At this time, the centrifugal mechanism 5 is raised to a certain height by the lifting mechanism 3, and the staff can manually rotate the conical sand removal screen 5013. The key 5017, which is locked in the groove 5016 on the outer wall of the rotating shaft 5011, will slide out along the track of the groove 5016 as the staff lifts the conical sand removal screen 5013.

[0037] In one embodiment, for the circular sand removal mesh 5021 and the conical sand removal mesh 5013, the sidewalls of both the circular sand removal mesh 5021 and the conical sand removal mesh 5013 are provided with a number of equidistantly arranged through holes 5028. The three through holes 5028 located on two adjacent straight lines are staggered, so that starch and impurities are more fully separated under the action of centrifugal force, thereby improving the sand removal efficiency and separation accuracy.

[0038] In one embodiment, the cover plate 4 has an annular limiting groove 9 at its bottom end that cooperates with the annular limiting block 5025, which effectively prevents the cover plate 4 from shifting or loosening during equipment operation, thereby ensuring the safety and reliability of the centrifugal mechanism when it is running at high speed.

[0039] In one embodiment, the cone slope of the cone-shaped sand removal screen 5013 is the same as that of the centrifuge tank 2, which allows the starch to slide more smoothly into the collection area under the combined action of gravity and centrifugal force, effectively avoiding accumulation or blockage, thereby ensuring the continuity and stability of the production process.

[0040] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0041] like Figures 1-5 As shown, in practical application, the operator first connects the feed inlet 7 to the starch pipeline to be processed. Next, the cleaned conical desanding screen 5013 is engaged with the rotating shaft 5011 via the groove 5016 and key 5017. Then, the cylinder 301 is activated via the control panel 6 (the specific working principle of the lifting mechanism 3 is described above), causing the lifting mechanism 3 to descend and precisely place the cover plate 4 on top of the centrifuge tank 2, achieving a seal. When starch enters the centrifuge mechanism 5 from the feed inlet 7, the servo motor 5015 is activated, and the rotating shaft 5011 begins to rotate (the specific working principle of the centrifuge mechanism 5 is described above), thereby driving the cross bracket 5012 to rotate the conical desanding screen 5013. Under the combined action of the first ratchet 5014 and the second ratchet 5024, the circular desanding screen 5021 also rotates synchronously, achieving a highly efficient centrifugation effect. Due to the design of the conical sand removal screen 5013 and the circular sand removal screen 5021, impurities such as sand and gravel are intercepted and eventually fall into the conical sand removal screen 5013, while the starch after sand removal is discharged through the discharge pipe 8. After the sand removal process is completed, the servo motor 5015 is stopped via the control panel 6, and the cylinder 301 is started to rise, raising the centrifugal mechanism 5 to the designated position. At this time, the operator can manually rotate the conical sand removal screen 5013 to disengage it from the groove 5016 on the outer wall of the rotating shaft 5011. The key 5017, which is engaged with the rotating shaft 5011, will slide out along the track of the groove 5016, making it easy to quickly remove the conical sand removal screen 5013 for subsequent cleaning.

Unless otherwise explicitly limited, those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
