Description

Technical Field

[0001] This utility model relates to the field of grading device technology, specifically a cocoa powder air separation and grading device. Background Technology

[0002] The cocoa powder air classifier is a device used to screen and classify cocoa powder to obtain cocoa powder of different fineness. The air classifier is one of the commonly used devices in the cocoa powder grading process and is widely used in practice.

[0003] In practical applications, the existing grading devices have relatively complete structures and functions, and can basically meet daily usage needs. However, the following problems still exist: In actual use, cocoa powder enters the grading box from the feed pipe by the pressure of external equipment. At this time, cocoa powder of different particles are mixed together. The larger particles will fall down, but they will also carry smaller particles down with them and be pressed to the bottom by the larger particles, thus making it impossible to complete the sorting. At the same time, a small number of larger particles will be discharged from the discharge pipe due to collisions and other reasons, which will reduce the efficiency and quality of sorting and cause great inconvenience.

[0004] Therefore, this utility model provides a cocoa powder air separation and grading device. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a cocoa powder air separation and grading device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a cocoa powder air-separation and grading device, comprising a grading box, an inlet pipe on one side of the grading box, an outlet pipe on the other side of the grading box, a stirring and filtering structure inside the grading box, the stirring and filtering structure comprising a rectangular ring frame, the rectangular ring frame being fixedly connected to the inner wall of the grading box, a rectangular ring block being snapped into the inner wall of the rectangular ring frame, a filter screen plate being fixedly connected to the top of the rectangular ring block, a disassembly and assembly sorting structure being provided on the top of the grading box, the disassembly and assembly sorting structure comprising an L-shaped groove, the L-shaped groove being opened on the top of the grading box, an L-shaped plate being provided inside the L-shaped groove, a second motor being installed on one side of the L-shaped plate, a transmission rod being fixedly connected to the output end of the second motor, and a negative pressure fan blade being fixedly connected to one end of the transmission rod.

[0008] The technical effect of adopting the above-mentioned further solution is as follows: the first threaded clamp, in conjunction with the first and second threaded holes, allows the filter screen to be disassembled and assembled, so that larger particles are blocked at the bottom of the filter screen for filtration. Under the action of the first motor, the rotating rod can be driven to rotate, which in turn drives the flipping arc plate to rotate, thereby turning and stirring the cocoa powder particles at the bottom, and stirring the smaller cocoa powder particles to the top for easy filtration.

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.

[0017] like Figures 1-6 As shown, this embodiment provides a technical solution: a cocoa powder air classification and grading device, including a grading box 1, a feed pipe 2 on one side of the grading box 1, a discharge pipe 3 on the other side of the grading box 1, a stirring and filtering structure 4 inside the grading box 1, the stirring and filtering structure 4 including a rectangular ring frame 41, the rectangular ring frame 41 being fixedly connected to the inner wall of the grading box 1, a rectangular ring block 42 being snapped into the inner wall of the rectangular ring frame 41, a filter screen plate 43 being fixedly connected to the top of the rectangular ring block 42, a disassembly and assembly sorting structure 5 at the top of the grading box 1, the disassembly and assembly sorting structure 5 including an L-shaped groove 51, the L-shaped groove 51 being opened at the top of the grading box 1, an L-shaped plate 53 being provided inside the L-shaped groove 51, a second motor 58 being installed on one side of the L-shaped plate 53, and a transmission rod 59 being fixedly connected to the output end of the second motor 58. One end of the moving rod 59 is fixedly connected to a negative pressure fan blade 510. By setting up a stirring and filtering structure 4, under the action of the filter screen plate 43, larger cocoa powder particles can be screened, so that larger particles can be filtered to the bottom by the filter screen plate 43. At the same time, under the action of the turning arc plate 49, the large and small cocoa powder particles that have fallen to the bottom can be turned over, which facilitates screening. At the same time, under the action of the discharge chute 412, the particles that have fallen to the bottom can be cleaned. By setting up a disassembly and assembly sorting structure 5, under the action of the L-shaped plate 53 and the L-shaped chute 51, the negative pressure fan blade 510 and other structures can be disassembled and assembled, which facilitates maintenance. At the same time, under the action of the filter hole circular frame 513, the negative pressure fan blade 510 can be protected to prevent particles from adhering to the negative pressure fan blade 510.

[0018] Going a step further, such as Figures 3-4As shown: A rectangular block 44 is fixedly connected to the top of the filter screen 43. A first screw hole 45 is opened on one side of the rectangular block 44, and a second screw hole 46 is opened on one side of the grading box 1.

A rotating rod 411 is fixedly connected to the output end of the first motor 48. A flipping arc plate 49 is fixedly connected to the outer surface of the rotating rod 411. An arc groove 410 is opened on the outer surface of the flipping arc plate 49. The first threaded clamping rod 47 cooperates with the first screw hole 45 and the second screw hole 46 to disassemble and assemble the filter screen 43, so that larger particles are blocked at the bottom of the filter screen 43 for filtration. Under the action of the first motor 48, the rotating rod 411 can be driven to rotate, which in turn can drive the flipping arc plate 49 to rotate, which can then turn and stir the cocoa powder particles at the bottom, thereby turning the smaller cocoa powder particles to the top for easy filtration.

[0019] The above solution also has the problem of inconvenience in removing particles that have fallen to the bottom of the grading box 1, such as... Figure 5 As shown: In this scheme, a discharge trough 412 is provided on one side of the grading box 1. A rectangular sealing plate 413 is snapped into the inner wall of the discharge trough 412. A cover plate 414 is fixedly connected to one side of the rectangular sealing plate 413. A rectangular connecting block 415 is fixedly connected to the top of the cover plate 414. A third screw hole 416 is provided on one side of the rectangular connecting block 415. A fourth screw hole 417 is provided on one side of the grading box 1. A second threaded rod 418 is threadedly connected to the inner wall of the third screw hole 416 and the fourth screw hole 417. Under the action of the rectangular auxiliary plate and the limiting slide rod, the screw hole cylinder can be assisted in limiting the movement of the screw hole cylinder along the first screw, so that it can cooperate with other components to play a role.

[0020] The above solutions also have the problem that the negative pressure fan blades 510 easily adhere to cocoa powder particles, such as... Figure 3 and Figure 6 As shown, a fifth screw hole 52 is provided on one side of the grading box 1, and a sixth screw hole 56 is provided on one side of the L-shaped plate 53. The inner walls of the fifth screw hole 52 and the sixth screw hole 56 are threaded with a third threaded clamp 57. A first sealing ring plate 54 is fixedly connected to the top of the L-shaped plate 53, a second sealing ring plate 55 is fixedly connected to one side of the L-shaped plate 53, an internal threaded ring plate 511 is fixedly connected to one side of the L-shaped plate 53, an external threaded ring plate 512 is threadedly connected to the inner wall of the internal threaded ring plate 511, and a filter hole frame 513 is fixedly connected to one side of the external threaded ring plate 512. Under the action of the L-shaped groove 51 and the L-shaped plate 53, the negative pressure fan blade 510 and other structures can be disassembled and assembled. Furthermore, under the action of the external threaded ring plate 512 and the internal threaded ring plate 511, the filter hole frame 513 can be disassembled and assembled, thereby preventing cocoa powder particles from adhering to the negative pressure fan blade 510.

[0021] Working principle: like Figure 1-6 As shown: In use, the rectangular ring block 42 is snapped into the rectangular ring frame 41, and the first threaded rod 47 is fixed to the first screw hole 45 and the second screw hole 46. The external threaded ring plate 512 and the internal threaded ring plate 511 are rotated and fixed, thereby allowing the filter hole frame 513 to be installed. At this point, the L-shaped plate 53 is placed on top of the grading box 1. The third threaded rod 57 is then fixed to the fifth screw hole 52 and the sixth screw hole 56, so that the L-shaped plate 53 can be installed. Start the first motor 48 and the second motor 58 so that the cocoa powder particles entering from the feed pipe 2 can be guided into the grading box 1. Then, under the action of the second motor 58, the negative pressure fan blade 510 can be rotated, which can be used to classify the cocoa powder. At the same time, under the action of the first motor 48, the flipping arc plate 49 can be rotated, which can be used to stir the cocoa powder particles that fall to the bottom. At this point, the second threaded rod 418 is separated from the third threaded hole 416 and the fourth threaded hole 417, so that the particles at the bottom can be taken out from the discharge trough 412.
