Description

Technical Field

[0001] This utility model relates to the technical field of medicinal material drying machines, specifically a multi-layer belt dryer. Background Technology

[0002] A medicinal herb dryer is a mechanical device specifically designed to remove excess moisture from Chinese medicinal herbs (such as ginseng, astragalus, and scrophularia). It effectively reduces the moisture content of plant, animal, or mineral-based medicinal herbs to the level required for safe storage or further processing through gentle, controlled heating and ventilation. Simultaneously, it maximizes the preservation of the herbs' active ingredients, shape, and color, ensuring their quality and efficacy.

[0003] During the process of drying medicinal herbs, peeling may occur when they fall off or are conveyed, causing the outer skin and dirt to stick to the conveyor belt. After a long drying period, the outer skin will stick tightly to the conveyor belt and be difficult to clean. Therefore, it is necessary to clean this residue as soon as possible to avoid affecting the circulation of hot air.

[0004] Nowadays, most cleaning methods are simple, directly using the rotation of brush rollers to sweep the surface of the conveyor belt to remove debris. However, brush roller cleaning alone cannot effectively remove the dried skin that has appeared on the surface of the conveyor belt, resulting in residue. Utility Model Content

[0005] To address the aforementioned problems in the existing technology, this utility model provides a multi-layer belt dryer, which has the advantage of better cleaning and removal of residues.

[0006] To achieve the aforementioned goal of higher installation stability, this utility model provides the following technical solution: it includes an integrated housing, a mesh belt assembly, and a cleaning assembly. The integrated housing is constructed by combining at least two frames, and the mesh belt assembly and the cleaning assembly are both housed within the integrated housing.

[0007] The conveyor belt assembly includes at least two conveyor belts, which are arranged alternately in a vertical fashion.

[0008] The cleaning assembly is located at the beginning of each conveyor belt and includes a brush roller and a brush slide plate. Several brush slide plates are provided and slide inside the brush roller. Each brush slide plate includes two brush plates that slide alternately.

[0009] Preferably, the brushing skateboard includes a first skateboard, a second skateboard, and a plurality of rollers disposed between the two first skateboards and the second skateboard.

[0010] Preferably, the bottom of the first skateboard is fixed with a first connecting block, the bottom of the first connecting block is rotatably connected with a first abutting wheel, and at least one first spring is provided on one side end face of the first skateboard; the bottom of the second skateboard is fixed with a second connecting block, the bottom of the second connecting block is rotatably connected with a second abutting wheel, and at least one second spring is fixed on one side end face of the second skateboard.

[0011] The first spring and the second spring are located on opposite sides of the brush slide, and the first slide and the second slide slide in opposite directions.

[0012] Preferably, a limiting fixing plate is movably connected inside the brush roller, and a limiting shaft is detachably installed on one end face of the limiting fixing plate through a special-shaped block. The limiting shaft is fixedly installed on the frame.

[0013] Preferably, at least one protrusion is provided on one side end face of the limiting and fixing plate, the protrusion being located on the side close to the mesh belt, and an irregularly shaped groove is provided on the other side end face of the limiting and fixing plate, the irregularly shaped groove being square and consistent with the shape of the irregularly shaped block.

[0014] Preferably, one side of the brush roller is connected to the motor via a belt.

[0015] Preferably, a partition is fixed to one end face of the frame.

[0016] Preferably, a hot air circulation group is also provided in each of the racks.

[0017] Compared with the prior art, this utility model provides a multi-layer belt dryer, which has the following beneficial effects:

[0018] 1. This multi-layer belt dryer uses brushes to clean residues on the conveyor belt. Each layer has a brush roller at the beginning, which cleans the conveyor belt before the medicine falls onto it, thus effectively preventing excessive residue adhesion and making subsequent conveyor belt cleaning difficult.

[0019] 2. This multi-layer belt dryer, through the staggered sliding first and second sliding plates, can add axial cleaning action on the basis of brush roller rotation cleaning, thereby further increasing the cleaning effect of the brush sliding plates. Especially when there are excessively sticky residues, the brushing action in two directions at the same time can greatly increase the possibility of brushing off the residues, making the cleaning more thorough.

Detailed Implementation

[0032] 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.

[0033] like Figure 1-11As shown, the assembly includes an integrated housing, a conveyor belt assembly, and a cleaning assembly. The integrated housing is composed of at least two frames 10. The length of the entire integrated housing can be increased by installing additional frames 10, thereby increasing the length of the production line. The conveyor belt assembly and the cleaning assembly are both housed within the integrated housing. A hot air circulation group is also installed within each frame 10. The hot air circulation group circulates hot air to dry the medicinal materials on the conveyor belt assembly. A partition 101 is fixed to one end face of the frame 10.

[0034] like Figure 3 As shown, the conveyor belt assembly includes at least two conveyor belts 20, preferably six layers. The first layer has a herb inlet on the left, and the fifth layer has a herb outlet on the right. The fifth layer is an extended section, and its extended portion is not equipped with hot air circulation. Therefore, it avoids contact with hot air before the product is conveyed to the outside, thereby reducing its temperature and accelerating the cooling of the medicine. The bottom layer is a scraper conveyor belt with scrapers installed on it, perpendicular to the direction of movement of the conveyor belt. The scrapers abut against the bottom of the integrated housing. When the conveyor belt moves the scrapers, they can push the medicine through the scrapers. The residue at the bottom of the integrated box is cleaned and disposed of to the outside to avoid manual cleaning. The mesh belts 20 are arranged in an alternating pattern, and each mesh belt 20 has a hollow design. Through the transmission of the mesh belts, the medicinal materials fall down layer by layer. Before the medicinal materials are dried, they may peel off during the falling or conveying process, causing the skin of the medicinal materials and dirt to stick to the conveyor belt of the mesh belt 20. After a long drying period, the skin will stick tightly to the mesh belt 20 and be difficult to clean. Therefore, this residue needs to be cleaned up as soon as possible to avoid affecting the circulation of hot air.

[0035] The cleaning component is set at the beginning of each mesh belt 20 and includes a brush roller 30 and a brush slide plate 31. There are several brush slide plates 31, which slide inside the brush roller 30. One end face of the brush roller 30 is connected to the motor via a belt. The brush roller 30 can be rotated by the belt drive, and the rotation direction is the same as the rotation direction of the mesh belt 20. The brush slide plate 31 includes two brush plates, which slide alternately.

[0036] The brushed sliding plate 31 includes a first sliding plate 311, a second sliding plate 312, and several rollers disposed between the two first sliding plates 311 and the second sliding plate 312, which allows the first sliding plate 311 and the second sliding plate 312 to slide more smoothly against each other without generating excessive friction. A first connecting block 3111 is fixed to the bottom of the first sliding plate 311, and a first abutting wheel 3112 is rotatably connected to the bottom of the first connecting block 3111. At least one first spring 3113 is disposed on one end face of the first sliding plate 311. A second connecting block 3121 is fixed to the bottom of the second sliding plate 312, and a second abutting wheel 3122 is rotatably connected to the bottom of the second connecting block 3121. The first abutting wheel 3112 and the second abutting wheel... The rotating installation of wheel 3122 reduces friction, making the brush slide plate 31 slide more smoothly. At least one second spring 3123 is fixed on one side end face of the second slide plate 312, wherein the first spring 3113 and the second spring 3123 are located on both sides of the brush slide plate 31. The first slide plate 311 and the second slide plate 312 slide in opposite directions. Each brush slide plate 31 is provided with bristles on the side end face away from the brush roller 30. These bristles can clean the residue on the mesh belt 20. Moreover, a brush roller 30 is provided at the beginning of each layer, so that the conveyor belt can be cleaned before the medicine falls onto the conveyor belt, thereby effectively avoiding the problem of excessive residue adhesion, which makes subsequent cleaning of the conveyor belt more difficult.

[0037] By setting up the first sliding plate 311 and the second sliding plate 312 in an alternating manner, an axial cleaning action can be added on the basis of the rotating cleaning action of the brush roller 30, thereby further increasing the cleaning effect of the brush sliding plate 31. Especially when there are excessively sticky residues, the possibility of brushing off the residues can be greatly increased by brushing in two directions at the same time, making the cleaning more thorough.

[0038] The brush roller 30 is also movably connected to a limiting fixing plate 301. A limiting shaft 302 is detachably installed on one end face of the limiting fixing plate 301 via a shaped block 3021. The limiting shaft 302 can be fixedly installed on the frame 10 by threads. One of the limiting shafts 302 is fixedly installed on the partition plate 101. At least one protrusion 3011 is provided on one end face of the limiting fixing plate 301. The protrusion 3011 is located on the side close to the mesh belt 20. When the brush roller 30 drives the brush slide plate 31 to rotate to the position of the protrusion 3011, an axial cleaning of the conveyor belt of the mesh belt 20 can be performed. A shaped groove 3012 is provided on the other end face of the limiting fixing plate 301. The shaped groove 3012 is square and is arranged in conjunction with the shaped block. The shapes of 3021 are consistent. The limiting and fixing plate 301 is restricted by the limiting shaft 302 so that it will not rotate. The brush roller 30 rotates itself, which drives the first abutting wheel 3112 and the second abutting wheel 3122 on the brush slide plate 31 to abut against the protrusion 3011. This causes the first slide plate 311 and the second slide plate 312 to squeeze the corresponding springs and slide in opposite directions. When they are separated from the protrusion 3011, the first slide plate 311 and the first slide plate 312 return to their original positions under the action of the spring. If continuous sliding in opposite directions is required, the number of protrusions 3011 can be increased so that when the brush slide plate 31 rotates to contact the mesh belt 20, multiple axial sliding can be generated to clean the conveyor belt on the mesh belt 20 axially.

[0039] Working principle: When in use, the limiting shaft 302 is fixedly installed on the frame 10. The limiting fixing plate 301 will not rotate due to the limiting of the limiting shaft 302. When the medicinal materials are drying, the motor is started and the brush roller 30 is rotated through the belt. At this time, the brush roller 30 can directly drive the brush slide plate 31 to perform circumferential cleaning on the conveyor belt.

[0040] When the brush slide plate 31 moves to the protrusion 3011, it is also positioned on the mesh belt 20. Then, through the abutment of the protrusion 3011, the second connecting block 3121 drives the second slide plate 312 to compress the second spring 3123. At the same time, the first connecting block 3111 drives the first slide plate 311 to compress the first spring 3113, thereby causing the first slide plate 311 and the second slide plate 312 to slide in opposite directions. At this time, the brush can perform an axial cleaning of the conveyor belt on the mesh belt 20, thereby enhancing its cleaning effect. When the brush slide plate 31 rotates to the point where it is disengaged from the protrusion 3011, under the action of the springs of the first slide plate 311 and the second slide plate 312, it moves back to its original position in the opposite axial direction, and this process is repeated.

[0041] In summary, this multi-layer belt dryer uses brushes to clean residues on the mesh belt 20. Each layer has a brush roller 30 at its starting end, allowing the conveyor belt to be cleaned before the medication falls onto it, effectively preventing excessive residue adhesion and making subsequent conveyor belt cleaning difficult. Furthermore, the staggered sliding first slide plate 311 and second slide plate 312 add axial cleaning action on top of the brush roller 30's rotational cleaning, further enhancing the cleaning effect of the brush slide plate 31. Especially when excessive residues are present, the simultaneous brushing action in two directions greatly increases the likelihood of removing the residues, resulting in a more thorough cleaning.
