High-temperature heat pump drying device

Abstract

The application discloses a high-temperature heat pump drying device, which comprises a box body, and a drying cylinder is fixedly connected to the inner cavity of the box body close to the top. When the application is used, the scraper is driven by the second motor to rotate to the horizontal state and is flush with the bottom of the slotted inner cavity, then two second electric rods are started to drive two movable plates to move relatively, so that the slotted side can be opened. Then, the air blower on the other side is started to work, so that the hot air generated after the heating pump is heated can be blown to the inner cavity of the drying cylinder. Because the weights of the damp medicinal materials and the dry medicinal materials are different, the medicinal materials that have been dried on the top of the scraper can be blown out of the slotted side, and the medicinal materials can be guided into the inner cavity of the frame body under the arrangement of the guide plate. Through the arrangement of the branch air blowing pipe, the small amount of damp medicinal materials in the inner cavity of the frame body can be dried again. Through the discharge of the dry medicinal materials in the inner cavity of the drying cylinder, the dried medicinal materials can be prevented from contacting the damp medicinal materials again, and the drying efficiency of the medicinal materials is improved.

Description

Technical Field

[0001] This invention relates to the field of drying equipment technology, and in particular to a high-temperature heat pump drying device. Background Technology

[0002] In the pharmaceutical industry, medicinal materials need to be dried in order to facilitate preservation and to reduce their weight and volume for easier transportation. Since high-temperature heat pumps can utilize the waste heat discharged during the drying process for circulating heating, they have advantages such as energy saving and environmental friendliness. Therefore, high-temperature heat pumps are currently widely used for drying medicinal materials.

[0003] Existing high-temperature heat pump drying devices typically pile the medicinal materials into a drying chamber and agitate them using a stirring mechanism to accelerate the drying process. However, because the upper layer of medicinal materials, after being dried by heat, will come into contact with the damp medicinal materials at the bottom again during subsequent stirring, the actual drying efficiency is not ideal.

[0013] Furthermore, a guide plate is provided at the top of the frame near the right side, and the guide plate is fixedly connected to the outer wall of the drying cylinder. The side of the guide plate facing the frame is inclined downwards.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The second motor drives the transmission shaft to rotate, which in turn drives the scraper to rotate. After the scraper is rotated to a horizontal position and flush with the bottom of the inner cavity of the side slot, the two second electric rods can be activated to push the two movable plates to move relative to each other, and drive the moving rack to move horizontally. This causes the arc-shaped cover plates on both sides to flip over and open the side slot. Then, the blower on the other side is started to work, so that the hot air generated by the heating pump can be blown into the inner cavity of the drying cylinder through the connecting pipe, the mounting cylinder, the conical exhaust hood and the main blowing pipe. Since the weight of the wet and dry medicinal materials is different, the medicinal materials that have been dried at the top of the scraper can be blown out through the side slot and guided into the inner cavity of the frame by the guide plate. The branch blowing pipe can be used to dry a small amount of wet medicinal materials in the inner cavity of the frame. By discharging the dry medicinal materials from the inner cavity of the drying cylinder, the dried medicinal materials are prevented from coming into contact with the wet medicinal materials again, thereby improving the drying efficiency of the medicinal materials.

[0015] 2. The first motor drives the rotating shaft to rotate, which in turn drives the first cam and the second cams on both sides to rotate simultaneously. When the first cam rotates, it can push the connecting shell to move up and down repeatedly, and drive the arc-shaped baffle to move up and down repeatedly in the inner cavity of the drying cylinder. This can lift the medicinal materials accumulated at the bottom of the inner cavity of the drying cylinder upwards and achieve the purpose of vertical turning. At the same time, the rotation of the second cams on both sides can drive the air-permeable mesh plate to move up and down repeatedly in the inner cavity of the frame, which can shake the medicinal materials on the air-permeable mesh plate up and down, further improving the drying efficiency of the medicinal materials.

[0016] 3. By activating the first electric lever, the lifting plate is pulled vertically upward, which in turn moves the slider upward. This causes the connecting shell to move vertically upward, increasing the gap between the connecting shell and the bottom slot after the shell enters the drying cylinder. This allows the medicinal materials inside the drying cylinder to be discharged from the bottom slot. When the lifting plate moves upward, the square connecting rod pushes the L-shaped baffle vertically upward, opening the discharge slot. This allows the medicinal materials inside the frame to be discharged downward and collected into the collection box, thus improving the convenience of collecting the medicinal materials.

[0021] The lifting mechanism includes a first cam 40, which is located directly below the connecting shell 5. A rotating shaft 41 is fixedly inserted through the first cam 40 near its top.

The left end of the rotating shaft 41 passes through the inner cavity of the bearing and is fixedly connected to the power output end of the first motor 42. The first motor 42 drives the rotating shaft 41 to rotate, which in turn drives the first cam 40 to rotate. The rotation of the first cam 40 pushes the connecting shell 5 to move up and down repeatedly, thereby turning the medicinal materials in the inner cavity of the drying cylinder 2 upward and improving the convenience of discharging the medicinal materials from the inner cavity of the drying cylinder 2.

[0022] The support mechanism includes a first electric rod 10, which is located at the top of the inner cavity of the groove 9.

The first electric rod 10 drives the lifting plate 11 to move vertically, thereby the slider 7 can drive the connecting shell 5 to rise and fall stably, and thus the height of the connecting shell 5 can be adjusted.

[0023] The reheating mechanism includes a frame 34, which is fixedly connected to the top of a load-bearing rod 33. A breathable mesh plate 36 is provided inside the frame 34, and a push rod 37 is fixedly connected to the bottom of the breathable mesh plate 36.

The branch air pipe 51 is equipped with a second solenoid valve 52. When the medicinal materials blown out of the drying cylinder 2 fall into the inner cavity of the frame 34, the second cam 43 can be rotated by the rotating shaft 41. The rotation of the second cam 43 pushes the push plate 39 to move up and down repeatedly, and drives the breathable mesh plate 36 to move up and down repeatedly, thereby shaking the medicinal materials in the inner cavity of the frame 34 and improving the drying efficiency of the medicinal materials.

[0024] A feeding slot 35 is provided at the bottom of the frame 34 facing the drying cylinder 2, and an L-shaped baffle 44 is slidably connected to the outer wall of the feeding slot 35.

When the first electric rod 10 drives the lifting plate 11 to move upward, it can drive the square connecting rod 45 to move synchronously, thereby driving the L-shaped baffle 44 to move up and down. When the L-shaped baffle 44 moves upward, the feeding slot 35 can be opened and the dried medicinal materials can be discharged.

[0025] The sealing mechanism includes an arc-shaped cover plate 26, which is fitted onto the outer wall of the side slot 3.

A second through hole is provided on the movable plate 30 near the top, and a crossbar 32 slides through the inner cavity of the second through hole. One end of the crossbar 32 is fixedly connected to the inner wall of the box 1. By sealing the side slot 3 with the arc-shaped cover plate 26, the undried medicinal materials are prevented from leaking out during the process of turning the medicinal materials.

[0026] The material turning mechanism includes a scraper 23, which is disposed in the inner cavity of the drying cylinder 2. One side of the scraper 23 is fitted against the inner wall of the drying cylinder 2, and a drive shaft 24 is fixedly fixed through the scraper 23. The drive shaft 24 is located at the center of the inner cavity of the drying cylinder 2, and the rear end of the drive shaft 24 is rotatably connected to the inner wall of the box body 1. A second motor 25 is disposed on the front side of the box body 1, and the front end of the drive shaft 24 is fixedly connected to the power output end of the second motor 25. The second motor 25 drives the drive shaft 24 to rotate, which in turn drives the scraper 23 to rotate in the inner cavity of the drying cylinder 2, thereby circulating and turning the medicinal materials in the inner cavity of the drying cylinder 2, improving the drying efficiency.

[0027] A rectangular cover plate 14 is attached to the top of the feeding hopper 13, and a second handle is fixedly connected to the top of the rectangular cover plate 14 near the right side. A fixed seat 15 is slidably connected to the bottom left side of the rectangular cover plate 14, and the fixed seat 15 is installed and fixed on the top of the box body 1. When feeding medicinal materials, the second handle can be pulled and the rectangular cover plate 14 can be moved horizontally to the left to open the feeding hopper 13, so as to facilitate the feeding of medicinal materials into the drying cylinder 2. After the medicinal materials are fed, the second handle can be pulled to move in the opposite direction, and the rectangular cover plate 14 can be used to seal the feeding hopper 13, thereby improving the sealing of the drying cylinder 2 and preventing heat loss and energy waste.

[0028] A guide plate 56 is provided on the top right side of the frame 34, and the guide plate 56 is fixedly connected to the outer wall of the drying cylinder 2. The side of the guide plate 56 facing the frame 34 is inclined downward. Through the setting of the guide plate 56, the medicinal materials discharged from the side slot 3 can be guided into the inner cavity of the frame 34 to avoid spillage of the medicinal materials.

[0029] Working principle: In use, firstly, pulling the first handle moves the rectangular cover 14 horizontally to the left. After opening the feed hopper 13, the medicinal materials can be fed into the inner cavity of the drying cylinder 2 through the feed hopper 13 and feed pipe 12. After pulling the rectangular cover 14 back to its original position and resetting the feed hopper 13, the heating pump 17 is activated, and hot air is delivered into the inner cavity of the drying cylinder 2 through the air inlet pipe 18, thus drying the medicinal materials. Next, the second motor 25 is activated, driving the transmission shaft 24 to rotate. The rotation of the transmission shaft 24 drives the scraper 23 to rotate, thus turning the medicinal materials. When the scraper 23 reaches its highest point, the first motor 42 is activated, driving the rotating shaft 41 to rotate. The rotation of the rotating shaft 41 drives the first cam 40 to rotate. The cam 40 rotates, pushing the connecting shell 5 to move vertically upwards. This allows the medicinal materials to be flipped upwards by the arc-shaped baffle 6. This cyclical operation enables rapid drying of the medicinal materials. During the drying process, two second electric rods 31 can be activated to push two movable plates 30 to move relative to each other, which in turn drives two moving racks 29 to move relative to each other. The movement of the moving racks 29 drives the rotating gear 28 to rotate, which in turn drives the arc-shaped cover plate 26 to flip over via the rotating rod 27. After the arc-shaped cover plates 26 on both sides move away from the side slots 3, the second motor 25 drives the scraper 23 to rotate to a horizontal position. Then, the blower 53 on the other side is activated, which blows the hot air from the inner cavity of the mounting box 16 onto the drying cylinder 2. With the side slots 3, the scraper can be rotated to dry the medicinal materials. The herbs on plate 23 are blown, which in turn blows the dried herbs through the side slot 3 to the outside of the drying cylinder 2, and guides them into the inner cavity of the frame 34 under the setting of the guide plate 56. When the rotating shaft 41 rotates, it drives the second cams 43 on both sides to rotate, and pushes the breathable mesh plates 36 on both sides to shake up and down, thereby shaking the herbs that fall on the breathable mesh plates 36. With the help of the branch blowing pipe 51, air is blown downward, thereby drying a small amount of undried herbs in the inner cavity of the frame 34. During the drying process, the hot air in the inner cavity of the box 1 is drawn back to the inner cavity of the mounting box 16 by the setting of the fan 22, and the returned hot air is dried under the setting of the dryer 21, thereby realizing the circulating heating of the device. After drying, the first electric rods 10 on both sides are activated to pull the lifting plate 11 vertically upward, thereby pulling the connecting shell 5 vertically upward under the setting of the two sliders 7. The inclined setting of the side of the connecting shell 5 can increase the gap between the connecting shell 5 and the bottom slot 4, thereby discharging the medicinal materials in the inner cavity of the drying cylinder 2 and collecting them into the collection box 46. In addition, when the lifting plate 11 moves upward, the square connecting rod 45 can push the L-shaped baffle 44 upward and open the feeding slot 35, so that the medicinal materials in the inner cavity of the frame 34 can be discharged downward through the feeding slot 35 and collected into the collection box 46 at the same time. The staff can take out the collection box 46 after opening the sealing door 55 to complete the collection of medicinal materials.
