Description

Technical Field

[0001] The utility model relates to the technical field of heat pump dryers, in particular to a heat pump dryer which is easy to disassemble and assemble. Background Art

[0002] Heat pump dryer can realize low-temperature air closed cycle drying, and the material drying quality is good. By controlling the working conditions of the device, the temperature of the hot dry air in the drying chamber is between 20 and 80°C, which can meet the high-quality drying requirements of most heat-sensitive materials. The closed cycle of the drying medium can avoid the impurity contamination of the material caused by the exchange with the outside gas, which is especially important for food, medicine or biological products. In addition, when the material is sensitive to oxygen in the air (easy to oxidize or burn and explode), inert medium can be used instead of air as the drying medium to achieve oxygen-free drying. The patent announcement number in China is CN213208448 U discloses a heat pump dryer that is easy to disassemble and assemble. In view of the problem that a few existing disassembled heat pump dryers can be simply installed by means of screws, etc., but need to unscrew the screws one by one for disassembly, which is not convenient enough, the following scheme is proposed, which includes a mounting seat, a frame fixedly installed in the mounting seat, a first partition plate fixedly installed in the frame, first springs fixedly connected to the inner walls on both sides of the frame, one side of the two first springs fixedly connected to the first baffle plates, one side of the two first baffle plates respectively fixedly connected to the first rack and the second rack, the bottom of the mounting seat is rotatably connected to a rotating rod, the rotating rod passes through the bottom of the mounting seat and is located in the frame, and one end of the rotating rod is fixedly connected to a gear.

[0003] In the above technical solution, when the dryer is disassembled, the inclined rod is inserted, and the inclined rod will resist the inclined block from compressing the second spring. At the same time, the inclined block drives the connecting rod to disengage from the second baffle plate. At the same time, the third spring releases the elastic force to drive the second fixing pin to disengage from the two first circular holes through the second baffle plate. At the same time, the rotating rod is twisted to drive the first rack and the second rack to approach each other through the gear. The first rack and the second rack drive the two first fixing pins to disengage from the two second support columns through the two first baffle plates, so that the second support column can be released. The fixation, and then the dryer is pulled upward to make the second support column disengage from the groove, and the disassembly work is completed.

[0004] However, through the above operation, the disassembly work of the heat pump dryer is relatively troublesome. When the rotating rod is rotated, the staff needs to keep pressing the plug rod, and the heat pump dryer needs to be pulled upward to be taken out, which makes it inconvenient to take out the heat pump dryer.

[0005] A heat pump drying machine that is easy to disassemble and assemble is proposed for this reason. Utility Model Content

[0026] like Figure 1-2As shown, a heat pump dryer that is easy to disassemble and assemble comprises a fixed shell 1 and a dryer body 2. A support column 3 is arranged at the bottom of the dryer body 2, and the number of the support columns 3 is set to four. A lifting mechanism 4 for height adjustment is arranged inside the fixed shell 1. A fixing mechanism 5 for clamping and fixing the support column 3 is arranged on one side of the lifting mechanism 4, and the fixing mechanism 5 is arranged inside the fixed shell 1. A driving mechanism 6 for providing stable power to the entire device is arranged on one side of the lifting mechanism 4. In this embodiment, when in use, the dryer body 2 with the support column 3 is placed on the lifting mechanism. 4, and then the driving mechanism 6 drives the lifting mechanism 4 to move downward, and the dryer body 2 and the supporting column 3 move downward accordingly. When the lifting mechanism 4 moves downward, it will trigger the fixing mechanism 5 to clamp and fix the supporting column 3 on the lifting mechanism 4, and the dryer body 2 will be fixed accordingly. Conversely, when the driving mechanism 6 drives the lifting mechanism 4 to move upward, the dryer body 2 and the supporting column 3 will move upward accordingly, and the lifting mechanism 4 will trigger the fixing mechanism 5 to release the fixing of the supporting column 3, so that the dryer body 2 can be disassembled, thereby facilitating the installation and disassembly of the dryer body 2, and conveniently taking and placing the dryer body 2, simple operation, and strong practicality.

[0027] like Figure 2-4 As shown, the lifting mechanism 4 includes two bidirectional screw rods 401, which are rotatably installed in the interior of the fixed shell 1, and the shape of the bidirectional screw rods 401 is set to be T-shaped. A fixing ring is installed on the outer wall of the two bidirectional screw rods 401, and two slide grooves 402 are provided on the bottom of the inner wall of the fixed shell 1. Two slide plates 403 are threadedly installed on the outer walls of the two bidirectional screw rods 401, and the slide plates 403 are slidably installed on the inner walls of the slide grooves 402. In this embodiment, when the bidirectional screw rods 401 are rotated, the two slide plates 403 are driven to move closer to or away from each other in the slide grooves 402, and the setting of the fixing ring can avoid the two slide plates 403 from conflicting with each other on the bidirectional screw rods 401, and the shape setting of the bidirectional screw rods 401 can enhance the stability of the rotation of the bidirectional screw rods 401, thereby adjusting the distance between the two slide plates 403.

[0028] like Figure 3-4As shown, a shaft column 1 404 is installed on each of the four slides 403, and a double-ring rod 405 is rotatably installed on the outer wall of the four shaft columns 1 404, and a shaft column 2 406 is rotatably installed on the inner wall of the ring mouth of the four double-ring rods 405 away from the shaft column 1 404, and four fixed plates 407 are installed on the surface of the four shaft columns 2 406, and a support plate 408 is installed on the top of the four fixed plates 407. In this embodiment, when the four slides 403 move close to each other in pairs, the four double-ring rods 405 are driven to rotate on the four shaft columns 1 404 and the shaft column 2 406 respectively, resulting in an angle change, pushing the support plate 408 upward, conversely, when the four slides 403 move away from each other in pairs, the support plate 408 is pulled downward, thereby adjusting the height of the support plate 408.

[0029] like Figure 2-4 As shown, the fixing mechanism 5 includes four rectangular plates 501, and the four rectangular plates 501 are installed at the bottom of the support plate 408. Two bidirectional screw rods 502 are rotatably installed on the four rectangular plates 501. Gears 506 are installed on the outer walls of the two bidirectional screw rods 502. Two gear rods 507 are installed at the bottom of the inner wall of the fixing shell 1, and the gears 506 are meshed with the gear rods 507. In this embodiment, when the support plate 408 moves longitudinally, the rectangular plates 501, the bidirectional screw rods 502, and the gears 506 are driven to move upward, and the gears 506 roll on the gear rods 507 to drive the bidirectional screw rods 502 to rotate.

[0030] like Figure 3-4 As shown, two fixing rods 503 are installed on the four rectangular plates 501, and four connecting plates 504 are threadedly installed on the outer walls of the two bidirectional screw rods 502, and the four connecting plates 504 are slidably installed on the outer walls of the two fixing rods 503, and clamping plates 505 are installed on the surfaces of the four connecting plates 504. The four support columns 3 are provided with clamping grooves, and the clamping plates 505 are slidably installed on the inner walls of the clamping grooves. In this embodiment, when the bidirectional screw rod 502 is rotated, the two connecting plates 504 are driven to slide away from each other on the fixing rods 503, and the two clamping plates 505 move accordingly and slide into the clamping grooves of the support columns 3 to clamp and fix the support columns 3. Conversely, the two connecting plates 504 slide close to each other on the fixing rods 503, and the two clamping plates 505 are separated from the clamping grooves of the support columns 3.

[0031] like Figure 1 , Figure 3-4As shown, the driving mechanism 6 includes two worm gears 601, the left ends of the two bidirectional screws 401 are extended to the outside of the fixed shell 1, and the worm gears 601 are installed on the surface of the bidirectional screws 401 at the extended ends, a protective shell 602 is installed on the left side of the fixed shell 1, a cylinder 603 is rotatably installed inside the protective shell 602, two worms 604 are installed on the outer wall of the cylinder 603, and the worms 604 are meshed with the worm gear 601, a motor 605 is installed at the front end of the cylinder 603, and the motor 605 is installed on the front side of the protective shell 602. In this embodiment, the motor 605 is started to drive the cylinder 603 to rotate, and the two worms 604 rotate accordingly, driving the two worm gears 601 to rotate, and the two bidirectional screws 401 rotate accordingly. Since the worm gear 601 and the worm 604 are self-locking, stable power is provided for the rotation of the two bidirectional screws 401.

[0032] In summary, when in use, the dryer body 2 with the support column 3 is placed on the lifting mechanism 4, and then the lifting mechanism 4 is driven downward by the driving mechanism 6, and the dryer body 2 and the support column 3 move downward accordingly. When the lifting mechanism 4 moves downward, it will trigger the fixing mechanism 5 to clamp and fix the support column 3 on the lifting mechanism 4, and the dryer body 2 will be fixed accordingly. Conversely, when the driving mechanism 6 drives the lifting mechanism 4 to move upward, the dryer body 2 and the support column 3 will move upward accordingly, and the lifting mechanism 4 will trigger the fixing mechanism 5 to release the support column 3, so that the dryer body 2 can be disassembled. The two-way screw 401 can be removed, thereby facilitating the installation and disassembly of the dryer body 2 and the placement and taking of the dryer body 2. The operation is simple and practical. When the two-way screw 401 rotates, the two slide plates 403 are driven to move closer to or away from each other in the slide groove 402. The setting of the fixing ring can prevent the two slide plates 403 from conflicting with each other on the two-way screw 401. The shape setting of the two-way screw 401 enhances the rotation stability of the two-way screw 401, thereby adjusting the distance between the two slide plates 403. When the four slide plates 403 move closer to each other in pairs, the four slide plates 403 are driven to move closer to each other in pairs. The double ring rods 405 rotate on the four shaft columns 1 404 and the shaft column 2 406 respectively, resulting in an angle change, pushing the support plate 408 upward. Conversely, when the four slide plates 403 move away from each other in pairs, the support plate 408 is pulled downward, thereby adjusting the height of the support plate 408. When the support plate 408 moves longitudinally, the rectangular plate 501, the two-way screw rod 2 502, and the gear 506 move upward, and the gear 506 rolls on the gear rod 507, driving the two-way screw rod 2 502 to rotate. When the two-way screw rod 2 502 rotates, the two connecting plates 504 are driven to be fixed. The two connecting plates 504 slide towards each other on the fixing rod 503, and the two connecting plates 505 move accordingly and slide into the clamping groove of the supporting column 3 to clamp and fix the supporting column 3. Conversely, the two connecting plates 504 slide towards each other on the fixing rod 503, and the two clamping plates 505 are separated from the clamping groove of the supporting column 3. The motor 605 is started to drive the cylinder 603 to rotate, and the two worms 604 rotate accordingly, driving the two worm wheels 601 to rotate, and the two bidirectional screws 401 rotate accordingly. Since the worm wheels 601 and the worm 604 are self-locking, stable power is provided for the rotation of the two bidirectional screws 401.
