Description

Technical Field

[0001] This invention belongs to the field of bovine bile powder production and processing technology, specifically relating to a vacuum belt drying device and method for bovine bile powder with a conformal feeding method. Background Technology

[0002] A vacuum belt dryer is a continuous feeding and discharging contact vacuum drying device. The material to be dried enters the high-vacuum dryer directly through a conveyor mechanism, spreading onto several drying belts within the dryer. A motor-driven, specially designed rollers move the drying belts at a set speed along the dryer cylinder. Each drying belt has three independent heating plates and one cooling plate underneath, with the drying belts in close contact with the heating and cooling plates, transferring the necessary energy for drying to the material through contact heat transfer. As the drying belt moves from one end of the cylinder to the other, the material has been dried and cooled. When the drying belt folds back, the dried material cake is peeled off the drying belt and, through a vertically moving chaff cutter, falls into a crushing device. The crushed material is then discharged through two air-lock-type discharge hoppers. Because the material directly enters a high vacuum and undergoes gradual drying over a period of time (usually 30-60 minutes), the resulting particles exhibit a certain degree of crystallization and, microscopically, contain micropores. After being directly pulverized to the required particle size, the granules have excellent flowability and can be directly compressed into tablets or capsules. Furthermore, due to their microscopic loose structure, they exhibit excellent solubility. The granules also have a pleasant appearance, significantly enhancing the perceived quality of instant (powder) products. The belt vacuum dryer features continuous feeding and discharging at both ends of the machine.

[0003] Ox bile powder is a dried product of bile. During its production and processing, a vacuum belt dryer is required. The inventor discovered that in existing vacuum belt dryers, only the bottom of the material contacts the heating plate. This means the bottom of the material dries first, while the surface, being further away from the heating plate, dries last. This results in uneven heating during the drying process, affecting overall drying efficiency and reducing the overall drying time.

[0004] Therefore, based on the inventor's extensive experience in design, development, and actual production in the relevant industry over many years, the inventor has researched and improved the existing structure and its shortcomings, and provided a vacuum belt drying device and method for ox bile powder with a bonding feeding method, in order to achieve a more practical purpose. Summary of the Invention

[0005] In view of at least one problem in the prior art, one object of the present invention is to provide a vacuum belt drying device and method for bovine bile powder with a conformal feeding method.

[0006] To achieve the above objectives, the present invention employs the following technical solution:

[0007] A vacuum belt drying device for bovine bile powder with a conformal feeding method includes a raw material tank, a vacuum dryer, a screw conveyor, a pulverizer, and a dry powder tank. The raw material tank, vacuum dryer, screw conveyor, pulverizer, and dry powder tank are connected by pipes. The vacuum dryer is equipped with a conveyor belt, and the bottom of the conveyor belt is equipped with a heating mechanism for drying the material. The vacuum dryer is also equipped with a fixedly connected separation plate, which is attached to the surface of the corresponding conveyor belt for material separation. A cutting blade that can move up and down is provided above the separation plate, and the separation plate is equipped with a cutting groove corresponding to the cutting blade. The cutting blade is equipped with multiple adjustment grooves, and a telescopic and rotatable flipping rod is provided in the adjustment groove. A rotatable flipping plate is provided at the end of the flipping rod, and a baffle is provided at the discharge end of the separation plate.

[0008] Preferably, each of the adjustment grooves is provided with a rotatable adjustment rod, the end of which is provided with a shrinkage groove. The flipping rod is disposed in the shrinkage groove and can move back and forth. The other side of the cutting blade is provided with a rotating groove that communicates with the corresponding adjustment groove, and the other side of the cutting blade is provided with multiple fixing plates. The fixing plates are provided with a rotatably connected and retractable telescopic tube, and the extension end of the telescopic tube is connected to the adjustment rod.

[0009] Preferably, an adjusting shaft is provided for rotatably connecting the adjusting rod and the adjusting groove; the flipping rod is slidably and sealedly connected to the shrinking groove; a drive box is fixedly connected to the cutting blade; a drive plate that can move up and down is provided inside the drive box; and a discharge hole is provided on the drive box; a discharge pipe is provided on the discharge hole; the end of the discharge pipe is Y-shaped and is connected to the shrinking groove and the telescopic pipe respectively; and driving fluid is provided in the drive box, the discharge pipe, the shrinking groove and the telescopic pipe.

[0010] Preferably, a support plate fixedly connected to a vacuum dryer is provided above the conveyor belt, and a plurality of fixedly connected hydraulic rods are provided on the support plate. The extension ends of the hydraulic rods are fixedly connected to the cutting blade. A plurality of slidably connected drive rods are provided on the drive box. The drive rods are fixedly connected to the drive plate. A reset spring is provided inside the drive box for automatically restoring the drive plate to its initial position.

[0011] Preferably, the separating plate is provided with fixedly connected positioning plates on both sides, the positioning plates are fixedly connected to the inner wall of the corresponding vacuum dryer, and the end of the separating plate is provided with an inclined surface for separating the material from the conveyor belt.

[0012] Preferably, the separating plate is provided with a plurality of flipping grooves for rotating the flipping plate, and the flipping grooves are connected to the cutting grooves.

[0013] Preferably, a rotating shaft is provided between the end of the flipping rod and the flipping plate, and a torsion spring is provided on the rotating shaft to drive the flipping plate to rotate to the initial position.

[0014] A vacuum belt drying method for bovine bile powder with a lamination feeding system, using the aforementioned vacuum belt drying equipment for bovine bile powder with a lamination feeding system, includes the following steps:

[0015] S1 feeds the material into the raw material tank, and then the pump transports the material through the pipeline to the conveyor belt in the vacuum dryer. At the same time, the conveyor belt rotates, so that the material can be evenly spread on the conveyor belt.

[0016] S2 simultaneously heats and dries the material on the conveyor belt using the heating mechanism;

[0017] S3 After the bottom of the material has been dried and shaped, the material reaches the separation plate, which separates the material from the conveyor belt, causing the material to move onto the separation plate;

[0018] S4 When the end of the material contacts the baffle, control the cutting blade to move downward to cut the material. When the cutting blade moves to the cutting groove, the tilting plate is located in the cutting groove, causing the tilting plate to rotate to the bottom of the material. Then control the cutting blade to move upward, and the tilting plate drives one end of the material to move upward, while the other end of the material abuts against the baffle, thus making the material tilted.

[0019] When the material end rises to the set height, the control flipping rod extends and rotates simultaneously, so that the flipping plate can better rotate the cut material automatically. When the material rotation angle exceeds 90 degrees, the material will automatically rotate and move to the conveyor belt below, thus realizing the automatic cutting and flipping of the material, so that the other side of the material can be better heated by the heating mechanism in the conveyor belt.

[0020] While the material is being flipped, the remaining material continues to move slowly toward the baffle. By controlling the material conveying speed and the material cutting and flipping speed, the remaining material moves to the baffle again, the previous material has already been flipped, and the cutting blade returns to its initial position to wait for the next cut.

[0021] After being cut by the S7, the material is heated and dried more quickly on the other side as the conveyor belt moves. The heated and dried material then moves to the screw conveyor and is conveyed to the crusher, where it is crushed into powder and then stored in a dry powder tank.

[0022] Compared with the prior art, the present invention has the following technical effects:

[0023] During the cutting process, by controlling the extension and rotation of the flipping rod, the flipping plate is always positioned at the bottom of the material. This allows the flipping plate to better push the cut material around the baffle, enabling the material to flip over and its upper surface to rotate and lay flat on the conveyor belt. As the conveyor belt moves, the upper surface of the material continues to be heated and dried. This flipping heating method can more effectively improve the overall drying efficiency, making the material heat more evenly and improving the drying efficiency. Moreover, this flipping method does not require stopping the conveyor belt. Since the original conveyor belt's conveying speed is already very slow, and the cut material rotates around the baffle, subsequent materials continue to move towards the baffle while the previous material is rotating, without affecting the original conveyor belt's conveying efficiency.

Obviously, the described embodiments are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this invention.

[0037] It should be noted that when an element is referred to as being "set on" another element, it can be directly on the other element or may be interposed with another element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or may be interposed with another element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementations.

[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0039] Example 1, please refer to Figure 1 , Figure 2 and Figure 3 A vacuum belt drying device for bovine bile powder with a conformal feeding method includes a raw material tank 1, a vacuum dryer 2, a screw conveyor 3, a pulverizer 4, and a dry powder tank 5. The raw material tank 1, vacuum dryer 2, screw conveyor 3, pulverizer 4, and dry powder tank 5 are connected by pipes. The vacuum dryer 2 is equipped with a conveyor belt 21, and the bottom of the conveyor belt 21 is equipped with a heating mechanism for drying the material. The vacuum dryer 2 is also equipped with a fixedly connected separation plate 22, which is attached to the surface of the corresponding conveyor belt 21 for material separation. A cutting blade 23 that can move up and down is provided above the separation plate 22, and the separation plate 22 is equipped with a cutting groove 221 corresponding to the cutting blade 23. The cutting blade 23 is equipped with multiple adjusting grooves 231, and a telescopic and rotatable flipping rod 234 is provided in the adjusting groove 231. The end of the flipping rod 234 is equipped with a rotatable flipping plate 232. The discharge end of the separation plate 22 is also equipped with a baffle 224.

[0040] The separating plate 22 separates the material from the conveyor belt 21, and the cutting groove 221 on the separating plate 22 allows the cutting blade 23 to cut and separate the material more thoroughly during cutting. It also allows the tilting plate 232 to move better under the material, thus enabling the tilting plate 232 to better lift and rotate the material. The baffle 224 is designed to abut the bottom of the cut and separated material, preventing the material from moving with the conveyor belt 21, allowing the material to rotate better around the baffle 224. The design of the tilting rod 234 and the tilting plate 232 ensures that after the material is cut and separated by the cutting blade 23... First, the rotating plate 232 is controlled to rotate, and then the cutting blade 23 rises, allowing the material to be cut to rotate. However, as the material rotates, the rotating plate 232 gradually separates from the bottom of the material. Therefore, during the rising process of the cutting blade 23, the extension and rotation of the rotating rod 234 are controlled to ensure that the rotating plate 232 remains at the bottom of the material. This allows the rotating plate 232 to better push the cut material to rotate around the baffle 224, enabling the cut material to flip and allowing its upper surface to rotate and lay flat on the conveyor belt 21. As the conveyor belt 21 moves, the upper surface of the material continues to be heated and dried. This flipping heating method effectively improves the overall drying efficiency, ensuring more even heating of the material and increasing drying efficiency. Furthermore, this flipping method does not require stopping the conveyor belt 21, and since the original conveyor belt 21 has a slow conveying speed, coupled with the rotating of the cut material around the baffle 224, subsequent materials continue to move towards the baffle 224 during the rotation of the previous material, without affecting the conveying efficiency of the original conveyor belt 21. Additionally, in traditional dryers, after the material is dried and shaped, it needs to be cut into pieces by a cutting mechanism before entering the screw conveyor 3. This method... The pre-cutting, separation, and flipping method not only ensures more uniform heating and drying of materials, but also eliminates the need for subsequent cutting mechanisms, allowing materials to fall directly into the screw conveyor 3. This reduces the need for additional cutting mechanisms and effectively lowers costs. Furthermore, since traditional dryers typically use multiple conveyor belts 21 for transport, this cutting and separation method does not affect the height between the upper and lower conveyor belts 21. The cutting blade 23 and separation plate 22 of this application can be directly installed on the conveyor belt 21 at a predetermined position to perform the flipping and separation operation. This method is highly adaptable and easier to install.

[0041] Please see Figure 3 , Figure 4 , Figure 5 and Figure 6In this embodiment, each of the adjusting grooves 231 is provided with a rotatable adjusting rod 239. The end of each adjusting rod 239 has a contraction groove 235. A flipping rod 234 is movably positioned within the contraction groove 235. The other side of the cutting blade 23 has a rotating groove 233 connected to the corresponding adjusting groove 231, and the other side of the cutting blade 23 has multiple fixing plates 237. Each fixing plate 237 has a rotatably connected and retractable telescopic tube 236, the extension end of which is connected to the adjusting rod 239. The design of the telescopic tube 236, adjusting rod 239, and flipping rod 234 enables the telescopic and rotational movements of the flipping plate 232.

[0042] Please see Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 In this embodiment, an adjusting shaft 238 is provided for rotatably connecting the adjusting rod 239 and the adjusting groove 231. The flipping rod 234 is slidably and sealedly connected to the shrinking groove 235. The cutting blade 23 is provided with a fixedly connected drive box 241. The drive box 241 is provided with a drive plate 246 that can move up and down. The drive box 241 is also provided with a discharge hole 245. The discharge hole 245 is provided with a discharge pipe. The end of the discharge pipe is Y-shaped and the end of the discharge pipe is connected to the shrinking groove 235 and the telescopic pipe 236 respectively. The drive box 241, the discharge pipe, the shrinking groove 235 and the telescopic pipe 236 are all provided with driving fluid.

[0043] The design of the drive plate 246 and the discharge pipe allows for hydraulic drive. The up-and-down movement of the drive plate 246 controls the contraction of the flipping rod 234 within the contraction tank 235 and the extension of the telescopic tube 236. The diameter of the discharge end of the discharge pipe can control the rate at which the driving fluid enters the contraction tank 235 and the telescopic tube 236, thereby controlling the extension speed of the flipping rod 234 and the telescopic tube 236. This enables the flipping plate 232 to better rotate and flip the material.

[0044] In this embodiment, a support plate 24 fixedly connected to the vacuum dryer 2 is provided above the conveyor belt 21. The support plate 24 is provided with a plurality of fixedly connected hydraulic rods 242. The extended ends of the hydraulic rods 242 are fixedly connected to the cutting blade 23. The drive box 241 is provided with a plurality of slidably connected drive rods 243. The drive rods 243 are fixedly connected to the drive plate 246. The drive box 241 is provided with a reset spring 244 for driving the drive plate 246 to automatically return to its initial position.

[0045] The original cutting blade 23 is recycled and combined with hydraulic transmission. During the recycling process, the support plate 24 squeezes the drive rod 243, thereby controlling the movement of the drive plate 246. Hydraulic drive causes the telescopic tube 236 and the flipping plate 232 to extend at a set speed, realizing the flipping of the material. The design of the return spring 244 ensures that when the cutting blade 23 moves down to the initial position again, the drive rod 243 separates from the support plate 24. At this time, the return spring 244 can automatically drive the drive plate 246 to return to the initial position, thereby realizing the automatic return of the flipping plate 232 to the initial position.

[0046] In this embodiment, positioning plates 223 are fixedly connected to both sides of the separation plate 22. The positioning plates 223 are fixedly connected to the inner wall of the corresponding vacuum dryer 2. The end of the separation plate 22 is provided with an inclined surface 222 for separating the material from the conveyor belt 21. The design of the inclined surface 222 enables the material to be better separated from the conveyor belt 21.

[0047] In this embodiment, the separating plate 22 is provided with a plurality of flipping grooves 225 for rotating the flipping plate 232, and the flipping grooves 225 are connected to the cutting groove 221. The design of the flipping grooves 225 enables the flipping plate 232 to flip more effectively after entering the cutting groove 221.

[0048] In this embodiment, a rotating shaft is provided between the end of the flipping rod 234 and the flipping plate 232 for rotational connection, and a torsion spring is provided on the rotating shaft for driving the flipping plate 232 to rotate to the initial position.

[0049] The design of the torsion spring enables the flip plate 232 to automatically rotate into the adjustment groove 231 under the pressure of the material when the cutting blade 23 is cutting, thus achieving concealment. When the flip plate 232 moves into the cutting groove 221, the flip plate 232 automatically rotates and opens under the action of the torsion spring, so that the flip plate 232 automatically moves to the bottom of the material, thereby enabling the cutting blade 23 to automatically carry the material up and rotate during the rising process.

[0050] A vacuum belt drying method for bovine bile powder with a lamination feeding system, using the aforementioned vacuum belt drying equipment for bovine bile powder with a lamination feeding system, includes the following steps:

[0051] S1 feeds the material into the raw material tank 1, and then the material is transported through the pipeline to the conveyor belt 21 in the vacuum dryer 2 by the pump. At the same time, the conveyor belt 21 is rotated so that the material can be evenly spread on the conveyor belt 21.

[0052] S2 simultaneously causes the heating mechanism to heat and dry the material on the conveyor belt 21;

[0053] S3 After the bottom of the material has been dried and shaped, the material reaches the separation plate 22. The separation plate 22 separates the material from the conveyor belt 21, so that the material moves onto the separation plate 22.

[0054] S4 can be equipped with a distance sensor or a pressure sensor on the baffle 224. When the end of the material contacts the baffle 224, the cutting blade 23 is controlled to move downward to cut the material. When the cutting blade 23 moves to the cutting groove 221, the tilting plate 232 is located in the cutting groove 221. Under the action of the torsion spring, the tilting plate 232 automatically rotates to the bottom of the material. Then the cutting blade 23 is controlled to move upward, and the tilting plate 232 drives one end of the material to move upward, while the other end of the material abuts against the baffle 224, so that the material is tilted.

[0055] When the material end rises to the set height, the end of the drive rod 243 contacts the support plate 24, thereby squeezing the drive plate 246 to move. Through hydraulic transmission, the telescopic tube 236 and the flipping rod 234 extend simultaneously, thereby controlling the extension and rotation of the flipping rod 234. By controlling the different thicknesses of the discharge end of the discharge pipe and the different amounts of drive fluid entering, the extension speed of the telescopic tube 236 and the extension speed of the flipping rod 234 are controlled at the set values, so that the flipping plate 232 can better automatically rotate the cut material. When the material rotation angle exceeds 90 degrees, the material will automatically rotate and move to the conveyor belt 21 below, thereby realizing the automatic cutting and flipping of the material, so that the other side of the material can be better heated by the heating mechanism in the conveyor belt 21.

[0056] While the material is being flipped, the remaining material continues to move slowly toward the baffle 224. The speed of material conveying and the speed of material cutting and flipping are controlled so that before the remaining material moves to the baffle 224 again, the previous material has already been flipped, and the cutting blade 23 returns to its initial position to wait for the next cut. When the cutting blade 23 moves down to its initial position, the drive rod 243 separates from the support plate 24, and the drive plate 246 automatically returns to its initial position under the action of the return spring 244, so that the flipping plate 232 automatically returns to its initial position.

[0057] The material cut by S7 will be heated and dried more quickly on the other side as the conveyor belt 21 moves. After being heated and dried, the material will move to the screw conveyor 3 along the conveyor belt 21 and be transported to the crusher 4, where it will be crushed into powder and then transported to the dry powder tank 5 for storage.

The speed of material conveying and the speed of material cutting and turning over are controlled, so that the remaining material moves to the front of the baffle again, the previous material has completed turnover, and the cutting knife returns to the initial position to wait for the next cutting; S7The cut material is heated and dried faster on the other side with the movement of the conveying belt. The material that has been heated and dried moves to the screw conveyor with the conveying belt, is conveyed to the pulverizer by the screw conveyor, is pulverized into powder, and is then conveyed to the dry powder tank for storage.
