Description

Technical Field

[0001] The present application relates to the technical field of capsule drying equipment, and in particular to a high-efficiency capsule drying device. Background Art

[0002] The capsules are made by filling drug powder or drug granules into large-end capsules and small-end capsules, and then fitting the large-end capsules and small-end capsules together to form drug capsules. However, the finished drug capsules often become moist due to prolonged contact with air during the filling process. Therefore, the drug capsules need to be dried with hot air.

[0003] At present, the general drying device uses a driving motor to move the pills on the conveyor belt into the cover, and the hot air blower on the connecting plate dries the pills with hot air. At the same time, the moisture generated after drying is fully absorbed by the desiccant to improve the quality of pill drying.

[0004] However, during the drying process of the above device, due to uneven drying, some capsules take too long to dry, which affects the quality of the capsules. Summary of the Invention

[0005] In order to improve the production quality of capsules, the present application provides a high-efficiency capsule drying device.

[0006] This application provides an efficient capsule drying device, which adopts the following technical solutions:

[0007] A high-efficiency capsule drying device, comprising:

[0008] The tank body is placed on the ground through a bracket, and the bottom end of the tank body is open;

[0009] A silo is detachably connected to the bottom of the tank body, and a plurality of heat conduction holes are opened at the bottom of the silo;

[0010] A heating bin is provided at the bottom end of the silo and is connected to an external heat generating tank via a connecting pipe, and is used to provide a hot air flow for the silo;

[0011] Collection components, including:

[0012] A plurality of gas pipes are provided, and the plurality of gas pipes are arranged around the vertical axis of the silo. The gas pipes are fixed to the inner wall of the silo, one end of the gas pipe is passed through the bottom of the silo and is located in the heating silo, and the other end of the gas pipe is located at the top of the silo and is inclined in a vertically upward direction along a direction close to the vertical axis of the silo;

[0013] The collecting trough is annular and fixed on the inner wall of the bottom end of the tank body, and the height of one side of the collecting trough is lower than the height of the other side;

[0014] The sterilization component is arranged on the tank body and is used for further sterilizing the capsules.

[0015] By adopting the above technical solution, the heating bin provides a hot air flow into the silo. The hot air flow ensures that heat can be evenly and efficiently transferred to the capsules in the silo, accelerating the drying process of the capsules. At the same time, the hot air flow provides a vertical thrust for the capsules, which is equal to the gravity of the capsules, allowing the capsules to float in the air and be easier to dry.

[0016] After the pellets are dried, the moisture content of the pellets decreases, the gravity is reduced, and the vertical force balance is broken. The pellets float upward and separate from the undried pellets. The hot air flow enters along one end of the air pipe and is sprayed toward the center of the silo from the other end, causing the pellets to be subjected to an oblique upward force. By decomposing the force, the vertical thrust of the pellets increases, causing the pellets to continue to float upward. At the same time, the pellets are subjected to a horizontal outward thrust, making it easy for the dried pellets to fall into the collection trough for timely collection. This can prevent the pellets from being heated for too long, thereby improving the production quality of the pellets.

[0017] Under the action of gravity, the capsules that fall into the collection trough automatically slide to the lower side for collection. The sterilization component sterilizes the collected capsules, thereby improving the hygiene and safety of the capsules and making it easier to further improve the production quality of the capsules.

[0018] Optionally, the air supply pipe adopts a Venturi tube, wherein the air supply pipe is divided into a straight pipe section A, a tapered section, a throat section, a diffusion section and a straight pipe section B in sequence along the bottom end of the silo toward the top end of the silo, and an air inlet hole is opened on the tapered section of the air supply pipe.

[0019] By adopting the above technical solution, the hot air flow flows at high speed in the Venturi tube. According to Bernoulli's principle, as the air flow flows in the tapering section, the flow velocity increases and the pressure decreases, forming a negative pressure area at the throat section of the Venturi tube and a positive pressure area outside the Venturi tube. Under the action of the pressure difference, the external hot air flow enters the Venturi tube through the air inlet, further increasing the flow velocity of the air flow, so that the hot air flow can be ejected more forcefully, ensuring that the capsules can accurately enter the collection tank, thereby improving the collection accuracy of the capsules.

[0020] Optionally, the sterilization component includes:

[0025] The driving part has two ends respectively connected to the sterilization box and the ultraviolet lamp, and the driving part is used to drive the ultraviolet lamp to move.

[0026] By adopting the above technical solution, the capsules that fall into the collection trough automatically slide into the lower side, and the capsules enter the sterilization box through the feeding pipe. The ultraviolet lamp uses the ultraviolet rays it emits to irradiate the capsules, which can effectively kill the microorganisms on the surface of the capsules. The driving part drives the ultraviolet lamp to move, thereby easily ensuring the uniformity of the sterilization effect, avoiding the occurrence of sterilization dead corners, and thus easily ensuring the sanitary quality of the capsules.

[0027] Optionally, the driving unit includes:

[0028] A motor, fixedly mounted on the sterilization box;

[0032] By adopting the above technical solution, the motor drives the screw to rotate, and under the limiting action of the guide rod, the screw drives the connecting block to move, and the connecting block drives the ultraviolet lamp to move, thereby easily achieving comprehensive irradiation and sterilization of the capsules in the sterilization box.

[0033] Optionally, the sterilization assembly further includes a moving portion, and the moving portion includes:

[0034] A rotating rod, rotatably connected to the sterilization box and arranged parallel to the guide rod;

[0035] A first synchronous wheel, fixedly sleeved on the screw;

[0036] A second synchronous wheel is fixedly mounted on the rotating rod, wherein a belt is mounted on both the first synchronous wheel and the second synchronous wheel;

[0041] By adopting the above technical solution, the connecting block drives bevel gear one and bevel gear two to move, the slot of bevel gear one moves along the clip strip of the rotating rod, the screw drives synchronous wheel one to rotate, synchronous wheel one drives the belt to rotate, the belt drives synchronous wheel two to rotate, synchronous wheel two drives the rotating rod to rotate, the clip strip of the rotating rod drives bevel gear one to rotate, bevel gear one drives bevel gear two to rotate, bevel gear two drives the transmission rod to rotate, and under the limiting action of the guide groove, the transmission rod drives the moving block to move in a direction perpendicular to the moving direction of the connecting block, thereby realizing multi-dimensional movement of the ultraviolet lamp in the sterilization box, so that the ultraviolet lamp can irradiate every corner of the sterilization box more comprehensively, thereby improving the sterilization efficiency and effect.

[0064] During use, the external heat generating tank 31 generates a hot air flow, and the air pump 33 draws the hot air flow into the heating chamber 3. The heating chamber 3 conducts the hot air flow from the heat conducting hole 21 into the silo 2. The hot air flow provides a vertical thrust for the capsules, and the thrust is equal to the gravity of the capsules, so that the capsules can float in the air and dry the capsules; then, the collection component 4 collects the dried capsules, and the sterilization component 5 further sterilizes the capsules, thereby easily improving the production quality of the capsules.

[0065] Reference Figure 1Tank 1 is cylindrical and vertically mounted. Silo 2 is cylindrical and vertically mounted, with an open top and a tapered bottom. Silo 2 is secured to a fixed frame 22, which is secured to a vehicle 23 for moving silo 2. Heating silo 3 is mounted on the ground, with an external heat generating tank 31 located to one side.

[0066] Reference Figure 2 and Figure 3 The bottom of the silo 2 is recessed inward, and the vertical cross-section of the silo 2 is trapezoidal. Multiple heat-conducting holes 21 are evenly arranged around the center of the top surface of the bottom of the silo 2. Heat-conducting sheet 1 211 is fixed to the heat-conducting holes 21. Heat-conducting sheet 1 211 is rectangular and inclined vertically upward in a direction away from the vertical axis of the silo 2.

[0067] Reference Figure 2 and Figure 3 The constricted sidewall at the bottom of the silo 2 is provided with heat transfer holes 24. Multiple groups of heat transfer holes 24 are evenly spaced around the vertical axis of the silo 2. Each group of heat transfer holes 24 has multiple heat transfer holes, and the multiple heat transfer holes 24 are evenly spaced along the slope of the bottom of the silo 2. Heat transfer holes 24 are fixed with heat conductive plates 241, which are tilted along the tangent line of the silo 2 and away from the vertical axis of the silo 2.

[0068] Reference Figure 2 The collecting assembly 4 includes an air pipe 41 and a collecting trough 42. There are multiple air pipes 41, and the multiple air pipes 41 are evenly arranged around the vertical axis of the silo 2. The air pipe 41 is fixed on the inner wall of the silo 2. One end of the air pipe 41 is passed through the bottom end of the silo 2 and is located in the heating bin 3. The other end of the air pipe 41 is located at the top of the silo 2 and is inclined in the vertical upward direction along the direction close to the vertical axis of the silo 2.

[0069] Reference Figure 3 In the embodiment of the present application, the air delivery pipe 41 adopts a Venturi tube, and the air delivery pipe 41 is divided into a straight pipe A section 411, a tapered section 412, a throat section 413, a diffusion section 414 and a straight pipe B section 415 in sequence along the bottom end of the silo 2 toward the top end of the silo 2, and an air inlet hole 4121 is opened on the tapered section 412 of the air delivery pipe 41.

[0070] Reference Figure 2 The collecting trough 42 is annular, and the wall of the collecting trough 42 is inclined vertically upward along the direction close to the vertical axis of the tank body 1. The collecting trough 42 is fixed on the inner wall of the bottom end of the tank body 1, and the height of one side is lower than the height of the other side.

[0071] During use, a portion of the hot air flow enters the silo 2 from the heat conducting holes 21 and pushes the capsules to circulate in the vertical direction; a portion of the hot air flow enters the silo 2 from the heat transfer holes 24 and drives the capsules to move in the circumferential direction; another portion of the hot air flow enters the air delivery pipe 41. The hot air flow flows at high speed in the Venturi tube. According to Bernoulli's principle, as the air flow flows in the tapered section 412, the flow velocity increases and the pressure decreases, forming a negative pressure area at the throat section 413 of the Venturi tube and a positive pressure area outside the Venturi tube. Under the action of the pressure difference, the external hot air flow enters the Venturi tube through the air inlet 4121, further increasing the flow velocity of the air flow, so that the hot air flow can be ejected more forcefully.

[0072] After the capsules are dried, the moisture content of the capsules decreases, the gravity is reduced, and the vertical force balance is broken. The capsules float upward and separate from the undried capsules. The accelerated hot air flow exerts an oblique upward force on the capsules. By decomposing the force, the vertical thrust of the capsules increases, and the capsules continue to float upward. At the same time, the capsules are subjected to a horizontal outward thrust, which makes it easy for the dried capsules to fall into the collection trough 42, facilitating timely collection and preventing the capsules from being heated for too long, thereby easily improving the production quality of the capsules.

The guide rod 523 is arranged parallel to the screw 522 and is fixed to the sterilization box 511.

[0075] Reference Figure 4 The connecting block 524 is in the shape of a rectangular block, the screw 522 and the guide rod 523 are both passed through the connecting block 524, the screw 522 is threadedly connected to the connecting block 524, the guide rod 523 is slidingly connected to the connecting block 524, the sliding direction of the connecting block 524 is the length direction of the sterilization box 511, and the ultraviolet lamp 513 is set on the connecting block 524.

[0076] Reference Figure 4The moving part 53 includes a rotating rod 531, a synchronous wheel 1 532, a synchronous wheel 2 533, a bevel gear 1 534, a bevel gear 2 535, a transmission rod 536 and a moving block 537. The rotating rod 531 is arranged parallel to the guide rod 523 and is located on the side of the screw 522 away from the guide rod 523. The rotating rod 531 is rotatably connected in the sterilization box 511.

[0077] Reference Figure 4 and Figure 5 Synchronous gear 1 532 is fixedly mounted on screw 522, while synchronous gear 2 533 is fixedly mounted on rotating rod 531. A belt 5331 is mounted on both synchronous gears 1 532 and 533. Bevel gear 1 534 is slidably mounted on rotating rod 531. A retaining strip 5311 is fixedly mounted on rotating rod 531, while bevel gear 1 534 has a retaining slot 5341, into which retaining strip 5311 slides.

[0078] Reference Figure 4 and Figure 5 Bevel gear 2 535 meshes with bevel gear 1 534 and is mounted on connecting block 524. Transmission rod 536 is coaxially fixedly coupled to bevel gear 2 535 and rotationally coupled to connecting block 524. Transmission rod 536 extends through and is threadedly coupled to movable block 537, to which UV lamp 513 is fixedly mounted. Connecting block 524 defines a guide slot 5241 within which movable block 537 can slide.

[0079] During use, the motor 521 drives the screw 522 to rotate. Under the limiting action of the guide rod 523, the screw 522 drives the connecting block 524 to move along the length direction of the sterilization box 511. The connecting block 524 drives the ultraviolet lamp 513 to move. In addition, the connecting block 524 drives the bevel gear 1 534 and the bevel gear 2 535 to move. The slot 5341 of the bevel gear 1 534 moves along the clip 5311 of the rotating rod 531.

[0080] At the same time, the screw 522 drives the synchronous wheel 1 532 to rotate, the synchronous wheel 1 532 drives the belt 5331 to rotate, the belt 5331 drives the synchronous wheel 2 533 to rotate, the synchronous wheel 2 533 drives the rotating rod 531 to rotate, the clamping strip 5311 of the rotating rod 531 drives the bevel gear 1 534 to rotate, the bevel gear 1 534 drives the bevel gear 2 535 to rotate, and the bevel gear 2 535 drives the transmission rod 536 to rotate. Under the limiting action of the guide groove 5241, the transmission rod 536 drives the moving block 537 to move in a direction perpendicular to the moving direction of the connecting block 524, thereby realizing the four-degree-of-freedom movement of the ultraviolet lamp 513 in the sterilization box 511. The ultraviolet rays kill the microorganisms on the surface of the capsules, so that the ultraviolet lamp 513 can more comprehensively irradiate every corner of the sterilization box 511, thereby improving the sterilization efficiency and effect.

[0081] The operating principle of the high-efficiency capsule drying device according to the embodiment of the present application is as follows: the air pump 33 draws a hot air flow into the heating chamber 3. A portion of the hot air flow enters the hopper 2 through the heat conducting holes 21 and the heat transfer holes 24, respectively, and propels the capsules to circulate in the vertical and circumferential directions. The other portion of the hot air flow enters the air delivery pipe 41. The hot air flow flows at a high speed in the Venturi tube. According to Bernoulli's principle, under the action of the pressure difference, the external hot air flow enters the Venturi tube through the air inlet hole 4121, thereby increasing the flow rate of the air flow and enabling the hot air flow to be ejected more forcefully.

[0082] After the pellets are dried, their weight is reduced, the vertical force balance is broken, and the pellets float upward, separating from the undried pellets. The accelerated hot air flow exerts an upward force on the pellets, increasing the vertical thrust of the pellets, causing them to continue to float upward. At the same time, the pellets are subjected to a horizontal outward thrust, making it easier for the dried pellets to fall into the collection trough 42, facilitating their timely collection. This can prevent the pellets from being heated for too long, thereby improving the production quality of the pellets.

[0083] Under the action of gravity, the capsules that fall into the collection trough 42 automatically slide to the lower side and enter the sterilization box 511 through the feeding pipe 512. The motor 521 drives the screw 522 to rotate. Under the limiting action of the guide rod 523, the screw 522 drives the connecting block 524 to move along the length direction of the sterilization box 511. The connecting block 524 drives the ultraviolet lamp 513 to move, and the connecting block 524 drives the bevel gear set to move.

[0084] At the same time, under the transmission action of the wheel group, the motor 521 drives the rotating rod 531 to rotate, and the clamping strip 5311 of the rotating rod 531 drives the bevel gear 1 534 to rotate. Under the transmission action of the bevel gear group, the bevel gear 1 534 drives the transmission rod 536 to rotate. Under the limiting action of the guide groove 5241, the transmission rod 536 drives the moving block 537 to move in a direction perpendicular to the moving direction of the connecting block 524, realizing the four-degree-of-freedom movement of the ultraviolet lamp 513 in the sterilization box 511. The ultraviolet rays kill the microorganisms on the surface of the capsules, so that the ultraviolet lamp 513 can irradiate every corner of the sterilization box 511 more comprehensively, thereby improving the sterilization effect and further improving the production quality of the capsules.
