Description

Technical Field

[0001] The utility model relates to the technical field of material conveying, in particular to a material conveying structure for a microwave dryer. Background Art

[0002] Belt microwave dryer is a highly efficient and advanced drying equipment, which is mainly composed of microwave generator, conveyor belt system, control system and other parts. Its working principle is to use microwave energy to heat the material, so that the moisture in the material evaporates rapidly, thereby achieving the purpose of drying.

[0003] Microwave dryers use a vibration device to spread the material flat onto a conveyor belt for material transportation. However, the traditional material conveying structure used in microwave dryers is prone to stratification of materials of different particle sizes during the vibration conveying process. Larger particles tend to concentrate in the lower layer, while smaller particles tend to be distributed in the upper layer. This stratification will cause different layers of materials to receive different amounts of energy during microwave drying. The upper layer of material may be over-dried due to its proximity to the microwave source and low density, while the lower layer of material may be under-dried, thus affecting the drying effect. Utility Model Content

[0004] The utility model discloses a material conveying structure for a microwave dryer, aiming to solve the technical problem that materials of different particle sizes are easily stratified during vibration conveying in the material conveying structure of the microwave dryer, with larger particles tending to concentrate in the lower layer and smaller particles tending to be distributed in the upper layer. Such stratification causes materials in different layers to receive different energies during microwave drying, and the upper layer material may be over-dried due to its proximity to the microwave source and low density, while the lower layer material may be under-dried, thereby affecting the drying effect.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A material conveying structure for a microwave dryer, comprising a microwave dryer body and a base located on one side of the microwave dryer body, and further comprising:

[0007] Unloading mechanism, used for uniform unloading of materials;

[0008] A mounting block is installed on the top outer wall of the base, a slide groove is opened on the top outer wall of the mounting block, a slider is connected to the inside of the slide groove, a material plate is installed on the top outer wall of the slider, and a plurality of first dividing strips and a plurality of second dividing strips are installed at equal distances on the bottom inner wall of the material plate;

[0009] A traction mechanism is used to pull the slider, and the traction mechanism includes a first motor installed on the outer wall of one side of the mounting block, the output end of the first motor is connected to a turntable, the edge of the outer wall of one side of the turntable and the outer wall of one side of the slider are connected to connecting blocks, and the outer walls of the two connecting blocks are sleeved with the same connecting rod.

[0010] In this solution, the turntable is driven to rotate by the first motor, and then the slider is driven to move back and forth by the connecting rod, so that the material plate swings back and forth, and the material flows through the top of the material plate during the vibration. Coupled with the slight vibration brought by the operation of the first motor, the combination of back and forth swinging and slight vibration will make the movement of material particles more complicated. Compared with simple vibration, this composite motion mode increases the chances of collision and mixing between different particles. Under the combined action of slight vibration and back and forth swinging, larger particles will not continue to sink simply due to inertia, and smaller particles will not always float on the upper layer, because their motion trajectories are disrupted by this composite motion. At the same time, the regular raised and depressed shapes formed by the first dividing strip and the second dividing strip make the material produce a more complex motion path during the swing and vibration of the material plate. Materials of different particle sizes are not only more evenly dispersed on the material plate, but also increase the chances of collision and mixing with each other, thereby further reducing stratification, making the material more evenly spread and improving the drying effect.

[0011] In a preferred embodiment, the unloading mechanism includes a fixed frame installed on the top outer wall of the base, the top outer wall of the fixed frame is provided with an opening, a hopper is installed on the top outer wall of the fixed frame, a second motor is installed on one side outer wall of the hopper, the output end of the second motor is connected to a rotating rod, and a plurality of baffles are installed at equal distances on the circumferential outer wall of the rotating rod, and the bottom end of the hopper corresponds to the highest position of the material plate.

[0012] The material is placed in the hopper, and the second motor drives several baffles to rotate, so that the material in the hopper is discharged evenly and orderly. The evenly ordered material can be better dispersed on the material plate, which is more conducive to evenly spreading the material.

[0013] As can be seen from the above, a material conveying structure for a microwave dryer includes a microwave dryer body and a base located on one side of the microwave dryer body, and further includes:

[0014] Unloading mechanism, used for uniform unloading of materials;

[0015] A mounting block is installed on the top outer wall of the base, a slide groove is opened on the top outer wall of the mounting block, a slider is connected to the inside of the slide groove, a material plate is installed on the top outer wall of the slider, and a plurality of first dividing strips and a plurality of second dividing strips are installed at equal distances on the bottom inner wall of the material plate;

[0016] A traction mechanism is provided for pulling the slider. The traction mechanism includes a first motor mounted on an outer wall of the mounting block. The output end of the first motor is connected to a turntable. The edge of the outer wall of the turntable and the outer wall of the slider are both connected to connecting blocks. The outer walls of the two connecting blocks are sleeved with a common connecting rod. The material conveying structure for a microwave dryer provided by this utility model has the technical effect of evenly distributing materials and improving drying efficiency.

[0022] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. The components of the embodiments of the present application generally described and marked in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work fall within the scope of protection of the present application.

[0023] The utility model discloses a material conveying structure for a microwave dryer, which is mainly applied to the material conveying structure of a traditional microwave dryer. Materials of different particle sizes are prone to stratification during vibration conveying. Larger particles tend to concentrate in the lower layer, while smaller particles tend to be distributed in the upper layer. This stratification causes materials in different layers to receive different energies during microwave drying. The upper layer of material may be over-dried due to its close distance to the microwave source and low density, while the lower layer of material may be under-dried, thereby affecting the drying effect.

[0024] Reference Figure 1 、 Figure 2 、 Figure 3 and Figure 4 A material conveying structure for a microwave dryer includes a microwave dryer body 1 and a base 5 located on one side of the microwave dryer body 1, and further includes:

[0025] Unloading mechanism, used for uniform unloading of materials;

[0026] A mounting block 4 is fixedly mounted on the top outer wall of the base 5. A slide groove is formed on the top outer wall of the mounting block 4. A slider 6 is movably connected to the inside of the slide groove. A material plate 10 is fixedly mounted on the top outer wall of the slider 6. A plurality of first dividing strips 11 and a plurality of second dividing strips 12 are fixedly mounted at equal distances on the bottom inner wall of the material plate 10.

[0027] The traction mechanism is used to pull the slider 6; the traction mechanism includes a first motor 7 fixedly mounted on the outer wall of one side of the mounting block 4, the output end of the first motor 7 is fixedly connected to a turntable 8, the edge of the outer wall of one side of the turntable 8 and the outer wall of one side of the slider 6 are fixedly connected with a connecting block, and the outer walls of the two connecting blocks are sleeved with the same connecting rod 9.

[0028] Among them, the material plate 10 is set to an inclined structure, and several first dividing strips 11 are distributed in a fan-shaped structure. The first dividing strips 11 and the second dividing strips 12 form regular raised and depressed shapes. The material plate 10 moves left and right along the slide groove through the slider 6, and the left and right movement range is 0-10 cm. During the shaking and vibration of the material plate 10, the material produces a more complex movement path. Materials of different particle sizes are not only dispersed more evenly on the material plate 10, but also increase the chances of collision and mixing with each other.

[0029] Among them, the sliding groove and the slider 6 are both set to a "convex" shape structure, and the sliding groove can limit the slider 6 to prevent the slider 6 from falling out of the sliding groove.

[0030] During specific use, the first motor 7 drives the turntable 8 to rotate, and pulls the slider 6 to move through the connecting rod 9. The slider 6 moves back and forth in the slide groove, so that the material plate 10 swings back and forth, and the material is discharged from the top of the material plate 10. While swinging, the material flows from the top to the bottom, passing through the first dividing bar 11 and the second dividing bar 12 on the way, plus the slight vibration brought by the first motor 7 when it is working. The combination of back and forth swinging and slight vibration will make the movement of material particles more complicated. Combined with the first dividing bar 11 and the second dividing bar 12, the material is dispersed more evenly on the material plate 10, and the chances of mutual collision and mixing are increased, making the material more evenly spread, thereby improving the drying effect.

[0031] Reference Figure 1 and Figure 4 In a preferred embodiment, the unloading mechanism includes a fixing frame 2 fixedly mounted on the top outer wall of the base 5, the top outer wall of the fixing frame 2 is provided with an opening, a hopper 3 is fixedly mounted on the top outer wall of the fixing frame 2, a second motor is fixedly mounted on one side outer wall of the hopper 3, a rotating rod 14 is fixedly connected to the output end of the second motor, and a plurality of baffles 13 are fixedly mounted at equal distances on the circumferential outer wall of the rotating rod 14, and the bottom end of the hopper 3 corresponds to the highest position of the material plate 10.

[0032] Specifically, the material is put into the hopper 3, and the second motor drives the baffle 13 to rotate. As the baffle 13 rotates, the material is discharged from the hopper 3 evenly and orderly, and then falls on the top of the material plate 10. The evenly and orderly material is more conducive to the subsequent material laying.

[0033] Working principle: When in use, the material is put into the hopper 3, and the second motor drives the baffle 13 to rotate. As the baffle 13 rotates, the material is discharged from the hopper 3 evenly and orderly, and then falls on the top of the material plate 10. The first motor 7 drives the turntable 8 to rotate and pulls the slider 6 to move through the connecting rod 9. The slider 6 moves back and forth in the chute, so that the material plate 10 swings back and forth, and the material is discharged from the top of the material plate 10. While shaking, the material flows from the top to the bottom, passing through the first dividing bar 11 and the second dividing bar 12 on the way, plus the slight vibration brought by the first motor 7 when it is working. The combination of back and forth shaking and slight vibration will make the movement of material particles more complicated, and combined with the first dividing bar 11 and the second dividing bar 12, the material is dispersed more evenly on the material plate 10, and the chances of mutual collision and mixing are increased, making the material more evenly spread, thereby improving the drying effect.

The replacements described may be partial structures, devices, or method steps, or they may be complete technical solutions. Any equivalent replacements or modifications based on the technical solution and the concept of the present invention shall be covered by the scope of protection of the present invention.
