Description
Technical Field
[0001] This utility model relates to the field of drying equipment technology, specifically to a large-scale air-source heat pump drying device. Background Technology
[0002] Large-scale air source heat pump drying equipment is an industrial device based on air source heat pump technology, designed for large-scale material drying needs.
[0003] Patent publication number CN 216048771 U discloses an air source heat pump drying device, including a chamber, an air source heat pump unit, a hot air chamber, and a drying chamber. The air source heat pump unit, the hot air chamber, and the drying chamber are respectively located on the lower inner wall of the chamber. The air source heat pump unit is connected to the outside of the chamber through an air inlet pipe. The air source heat pump unit is connected to the hot air chamber through an air outlet pipe. The hot air chamber is connected to the drying chamber through an air guide pipe. Sliding grooves are provided on both inner walls of the drying chamber.
[0004] To address the issue that existing equipment can carry powder from loosely structured materials into the air during hot air flow, which can affect the health of workers, current technology uses air ducts to guide hot air into the drying chamber to dry the materials on the shelves. During the drying process, a mesh cover prevents the exhaust of hot air containing debris, thus protecting the health of workers. However, this method still suffers from the problem that the stacking of medicinal materials can lead to uneven drying, resulting in inconsistent quality of the materials and thus reducing the practicality of the equipment. Utility Model Content
[0005] The purpose of this invention is to provide a large-scale air-source heat pump drying device to solve the problems mentioned in the background art.

[0007] The drying mechanism includes an air source heat pump unit, and a connecting pipe is fixedly connected to the output part of the air source heat pump unit. A sealing cover is fixedly connected to the end of the connecting pipe away from the air source heat pump unit.
[0008] A further improvement of the present invention is that the main structure includes a drying chamber, the top surface of the drying chamber is fixedly connected to a sealing cover and the two are sealed, a plurality of drying holes are evenly opened on the top surface of the drying chamber, and a chamber door is provided on the front side of the drying chamber.
[0009] A further improvement of the present invention is that the placement mechanism includes multiple placement boxes, which are arranged inside the drying chamber. The sides of the multiple placement boxes are provided with sliding grooves, and motor brackets are provided below the sliding grooves. The motor brackets are fixedly connected to the sides of the placement boxes.
[0010] A further improvement of this utility model is that: a feed inlet is fixedly connected to the top surface of the placement box, and a pull-out drawer is provided at the bottom of the placement box, with a handle fixedly connected to the surface of the pull-out drawer.
[0011] A further improvement of the present invention is that the screening mechanism includes four fixed blocks and a servo motor. The servo motor is fixedly installed on the top surface of the motor bracket. An eccentric wheel is fixedly connected to the output shaft of the servo motor. A connecting rod is movably connected to the eccentric column of the eccentric wheel.
[0012] A further improvement of this utility model is that: a second connecting rod is movably connected to the end of the first connecting rod, a slider is movably connected to the end of the second connecting rod, and the slider movably connected to the end of the second connecting rod is slidably connected to the slide groove.
[0013] A further improvement of this utility model is that: a sieving groove is fixedly connected to the back of the slider movably connected to the end of the second connecting rod; four fixed blocks are fixedly connected to the four corners of the placement box; a sieving device is provided on the top surface of the two front fixed blocks; a sieving groove is fixedly connected to the top surface of the sieving device; a connecting rod is fixedly connected to the bottom surface of the rear end of the sieving groove; movable grooves are movably connected to both sides of the connecting rod; and the movable grooves are fixedly connected to the top surface of the two back fixed blocks.
[0014] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows: 1. This utility model provides a large-scale air-source heat pump drying device. It consists of a drying mechanism comprised of a connecting pipe, an air-source heat pump unit, and a sealing cover, and a main body structure comprised of a drying chamber, drying holes, and a chamber door. These two components work together to heat the material placed inside the drying chamber and dry it. When needed, simply open the chamber door, place the material to be dried inside the drying chamber, and then start the air-source heat pump unit. The air-source heat pump unit converts air energy into heat energy, which is then transferred through the connecting pipe to the inside of the sealing cover. Because the sealing cover is sealed to the top of the drying chamber, the heat energy transferred to the inside of the sealing cover is then transferred to the drying chamber through the drying holes, thereby drying the material inside the drying chamber.
[0015] 2. This utility model provides a large-scale air-source heat pump drying device. It features a placement mechanism consisting of a placement box, inlet, chute, motor support, pull-out drawer, and handle; and a screening mechanism consisting of a screening trough, fixed block, screener, movable trough, connecting rod, servo motor, eccentric wheel, first connecting rod, and second connecting rod. These two mechanisms work together to screen the materials to be dried inside the drying chamber. This not only prevents uneven heating of stacked materials, thus avoiding inconsistent drying levels, but also allows for the screening of materials that shrink during drying, separating out high-quality materials. When needed, the materials to be dried simply need to be fed through the inlet. The material enters the placement box through the inlet, and then the servo motor is started. The output shaft of the servo motor drives the eccentric wheel to rotate, which in turn causes the eccentric column on the surface of the eccentric wheel to move the first connecting rod. This causes the first connecting rod to drive the second connecting rod to slide up and down inside the slide groove via the slider. This causes the front end of the screening trough to compress the rear end of the screening device, which moves through the connecting rod inside the movable groove, thus screening the material placed inside the screening trough. This prevents uneven heating of the stacked material, which would result in different drying degrees. Since drying will cause the material to shrink, the material placed inside the screening trough can also fall through the screen holes into the pull-out drawer. Then, by pulling the handle, the material can be taken out of the pull-out drawer. Attached Figure Description

[0018] The present invention will be further described in detail below with reference to embodiments: Example 1 like Figure 1-6 As shown, this utility model provides a large-scale air source heat pump drying device, including a drying mechanism 1, a main body 2 at the end of the drying mechanism 1, a placement mechanism 3 inside the main body 2, a sieving mechanism 4 inside the placement mechanism 3, the drying mechanism 1 including an air source heat pump unit 12, a connecting pipe 11 fixedly connected to the output part of the air source heat pump unit 12, a sealing cover 13 fixedly connected to the end of the connecting pipe 11 away from the air source heat pump unit 12, the main body 2 including a drying chamber 21, the top surface of the drying chamber 21 fixedly connected to the sealing cover 13 and the two are sealed, a plurality of drying holes 22 are evenly opened on the top surface of the drying chamber 21, and a chamber door 23 is provided on the front side of the drying chamber 21.
[0019] In this embodiment, a drying mechanism 1 consisting of a connecting pipe 11, an air-source heat pump unit 12, and a sealing cover 13, and a main body mechanism 2 consisting of a drying chamber 21, a drying hole 22, and a chamber door 23 are set up. The two work together to heat the device and dry the material placed inside the drying chamber 21. When needed, simply open the chamber door 23, place the material to be dried inside the drying chamber 21, and then start the air-source heat pump unit 12. The air-source heat pump unit 12 converts air energy into heat energy, which is transferred to the inside of the sealing cover 13 through the connecting pipe 11. Since the sealing cover 13 is sealed to the top surface of the drying chamber 21, the heat energy transferred to the inside of the sealing cover 13 is transferred to the drying chamber 21 through the drying hole 22, thereby drying the material inside the drying chamber 21.
[0020] Example 2 like Figure 1-6As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the placement mechanism 3 includes multiple placement boxes 31, which are arranged inside the drying chamber 21. A sliding groove 33 is provided on the side of each placement box 31, and a motor bracket 34 is provided below the sliding groove 33. The motor bracket 34 is fixedly connected to the side of the placement box 31. A feed inlet 32 is fixedly connected to the top surface of the placement box 31, and a pull-out drawer 35 is provided at the bottom of the placement box 31. A handle 36 is fixedly connected to the surface of the pull-out drawer 35. The screening mechanism 4 includes four fixing blocks 42 and a servo motor 46. The servo motor 46 is fixedly installed on the top surface of the motor bracket 34, and an eccentric wheel 47 is fixedly connected to the output shaft of the servo motor 46. The eccentric column of 47 is movably connected to a first connecting rod 48. The end of the first connecting rod 48 is movably connected to a second connecting rod 49. The end of the second connecting rod 49 is movably connected to a slider. The slider movably connected to the end of the second connecting rod 49 is slidably connected to the slide groove 33. The back of the slider movably connected to the end of the second connecting rod 49 is fixedly connected to a screening groove 41. Four fixed blocks 42 are fixedly connected to the four corners of the placement box 31. The top surface of the two front fixed blocks 42 is provided with a screening actuator 43. The top surface of the screening actuator 43 is fixedly connected to the screening groove 41. The bottom surface of the rear end of the screening groove 41 is fixedly connected to a connecting rod 45. The two sides of the connecting rod 45 are movably connected to movable grooves 44. The movable grooves 44 are fixedly connected to the top surface of the two back fixed blocks 42.
[0021] In this embodiment, a placement mechanism 3, consisting of a placement box 31, a feed inlet 32, a chute 33, a motor bracket 34, a pull-out drawer 35, and a handle 36, and a screening mechanism 4, consisting of a screening groove 41, a fixed block 42, a screening device 43, a movable groove 44, a connecting rod 45, a servo motor 46, an eccentric wheel 47, a first connecting rod 48, and a second connecting rod 49, are configured to screen the materials to be dried placed inside the drying chamber 21. This not only prevents uneven heating of stacked materials, which could lead to inconsistent drying levels, but also allows for the screening of materials that shrink during drying, separating out high-quality materials. When needed, the materials to be dried simply need to be fed into the placement box 3 through the feed inlet 32. In step 1, the servo motor 46 is then started. The output shaft of the servo motor 46 drives the eccentric wheel 47 to rotate, which in turn causes the eccentric column on the surface of the eccentric wheel 47 to move the first connecting rod 48. The first connecting rod 48 then drives the second connecting rod 49 to slide up and down inside the slide groove 33 via the slider. This causes the front end of the sieving groove 41 to compress the rear end of the sieving device 43 to move inside the movable groove 44 via the connecting rod 45. This causes the material placed inside the sieving groove 41 to be sieved, preventing uneven heating of the stacked material and resulting in different drying degrees. Since drying will cause the material to shrink, the material placed inside the sieving groove 41 can also fall through the sieve holes into the pull drawer 35. Then, by pulling the handle 36, the material placed in the pull drawer 35 can be taken out.
[0022] The working principle of this large-scale air-source heat pump drying device will be explained in detail below.
[0023] like Figure 1-6As shown, in use, simply open the door 23, place the material to be dried inside the drying chamber 21, and then start the air source heat pump unit 12. The air source heat pump unit 12 converts air energy into heat energy, which is transferred to the inside of the sealing cover 13 through the connecting pipe 11. Since the sealing cover 13 is sealed to the top surface of the drying chamber 21, the heat energy transferred to the inside of the sealing cover 13 is transferred to the drying chamber 21 through the drying hole 22, thereby drying the material inside the drying chamber 21. Then, the material to be dried enters the placement box 31 through the feed inlet 32. Then, start the servo motor 46. The output shaft of the servo motor 46 drives the eccentric wheel 4. 7. Rotation causes the eccentric column on the surface of the eccentric wheel 47 to drive the first connecting rod 48 to move. The first connecting rod 48 then drives the second connecting rod 49 to slide up and down inside the slide groove 33 via the slider. This causes the front end of the sieving groove 41 to compress the rear end of the sieving device 43 to move inside the movable groove 44 via the connecting rod 45. This causes the material placed inside the sieving groove 41 to be sieved, preventing uneven heating of the stacked material and resulting in different drying degrees. Since drying will cause the material to shrink, the material placed inside the sieving groove 41 can also fall through the sieve holes into the pull drawer 35. Then, by pulling the handle 36, the material placed in the pull drawer 35 can be taken out.
[0024] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
