Description

Technical Field

[0001] The utility model relates to the technical field of heat pump drying units, in particular to a high-temperature heat pump drying unit using a non-azeotropic working medium. Background Art

[0002] A non-azeotropic working fluid is a working fluid composed of two or more different working fluids mixed together in a certain proportion. The components of the liquid phase and the gas phase in equilibrium under a certain pressure are different, and the boiling point is not constant. The working principle of the high-temperature heat pump drying unit using a non-azeotropic working fluid is mainly based on the reverse Carnot principle, which absorbs heat from the surrounding environment and transfers it to the object to be heated (the object with a higher temperature).

[0003] Reference can be made to the existing literature for a high-temperature heat pump drying unit using a non-azeotropic working fluid (CN207702942U). The reference can perform remote data transmission and automatic control, and is equipped with a PLC integrated control cabinet that can load control instructions into the memory for storage and execution at any time, thereby realizing the automatic operation of the high-temperature heat pump drying unit. The wireless transmission module can be used to upload the working information of the high-temperature heat pump drying unit to the monitoring center. The monitoring center transmits wireless signals to realize remote control of the high-temperature heat pump drying unit, thereby improving the monitoring intensity and working efficiency of the high-temperature heat pump drying unit.

[0004] High-temperature heat pump drying units are generally fixedly installed in drying rooms. Due to daily operations, material in and out, and environmental humidity, a certain amount of dust and water vapor often accumulate in the drying room. When the equipment is not in use, the dust and water vapor in the drying room can easily enter the unit. Over time, the accumulation of internal dust and water vapor can easily affect the electrical components in the unit. Therefore, a high-temperature heat pump drying unit with a protective structure and using a non-azeotropic working fluid is designed. Utility Model Content

[0028] Reference Figure 1-5 A high-temperature heat pump drying unit using a non-azeotropic working fluid includes: a sealing cover 1, a sealing cover 1 and a heat pump dryer body 6. The heat pump dryer body 6 is arranged inside the sealing cover 1. A square slot 5 is opened on the top of the sealing cover 1 to fit the sealing plate 2. The sealing plate 2 cooperates with the sealing cover 1 to seal the heat pump dryer body 6 to reduce the entry of external dust and water vapor.

[0029] Specifically, a positioning seat 9 is integrally connected to the bottom of the heat pump dryer body 6 , and two positioning grooves 10 are provided on both sides of the positioning seat 9 . At the same time, a mounting seat 7 is provided inside the sealing cover 1 , and an adjustment component is provided above the mounting seat 7 .

[0030] For further information, please refer to Figure 3 Four pulleys 8 are provided at the bottom of the mounting seat 7, and two supporting rails 3 are fixedly installed at the inner bottom end of the sealing cover 1. The four pulleys 8 are all located inside the supporting rails 3 and slide, and the inner width of the supporting rails 3 fits the pulley 8.

[0031] At the same time, you can refer to Figure 3 The width of the mounting seat 7 matches the width of the inner groove of the sealing cover 1, and after the sealing plate 2 is inserted into the sealing cover 1, the sealing plate 2 fits with the mounting seat 7, and the bottom of the sealing plate 2 abuts against the two supporting slide rails 3, thereby allowing the heat pump dryer body 6 to be stored in a sealed space.

[0032] For details, please refer to Figure 5The adjustment assembly includes an adjustment seat 11 and an adjustment seat 2 12. A drive motor 13 is fixedly installed at one end of the adjustment seat 11. A bidirectional screw 14 is fixed to the output end of the drive motor 13. The bidirectional screw 14 is rotatably connected to the inside of the adjustment seat 11. At the same time, the external thread of the bidirectional screw 14 is connected to two threaded sleeves 15.

[0033] In this embodiment, the driving motor 13 is operated to drive the bidirectional screw 14 to rotate, so that the two threaded sleeves 15 connected to the outer threads of the bidirectional screw 14 move in opposite directions about the center of the bidirectional screw 14 .

[0034] Furthermore, a smooth guide rod 17 is fixed on the inner side of the adjustment seat 12, and two sliders 18 are slidably connected to the outside of the guide rod 17. A connecting frame 16 is fixedly connected between the slider 18 and the threaded sleeve 15, so that the two connecting frames 16 can move in opposite directions, and two positioning protrusions 19 are provided on one side of the connecting frame 16.

[0035] In this embodiment, the four positioning protrusions 19 can be moved in opposite directions to fit into the positioning grooves 10 on both sides of the positioning seat 9, thereby quickly locking the positioning seat 9 and completing the connection between the heat pump dryer body 6 and the mounting seat 7.

[0036] Specifically, such as Figure 1-2 As shown, two electric telescopic cylinders 4 are fixedly mounted on the rear side of the sealing cover 1 , and the output ends of the two electric telescopic cylinders 4 are fixed to the rear side of the mounting base 7 .

[0037] When the unit is running, the sealing plate 2 can be removed and placed under the two supporting slide rails 3 as a supporting structure, and then the two electric telescopic cylinders 4 are operated to drive the mounting seat 7 to move outward, and the four pulleys 8 under the mounting seat 7 move toward the outer supporting slide rails 3. At this time, the heat pump dryer body 6 is pushed to the sealing cover 1 for normal operation. At the same time, it is also convenient to disassemble the heat pump dryer body 6 after it is pushed out.

[0038] Working principle: When the present invention is in use, in the non-use state, the driving motor 13 is operated to drive the bidirectional screw 14 to rotate, so that the two threaded sleeves 15 connected to the external thread of the bidirectional screw 14 move in opposite directions with the center of the bidirectional screw 14, and the four positioning protrusions 19 move in opposite directions to fit into the positioning grooves 10 on both sides of the positioning seat 9, thereby quickly locking the positioning seat 9 to complete the connection between the heat pump dryer body 6 and the mounting seat 7, and then the heat pump dryer body 6 is hidden in the sealing cover 1, and then the sealing plate 2 is inserted from the slot 5 above the sealing cover 1 to seal the heat pump dryer body 6, thereby effectively preventing water vapor and dust in the drying room from entering the unit. When the unit is in use, the sealing plate 2 can be removed first and placed under the two supporting slide rails 3 as a supporting structure, and then the two sets of electric telescopic cylinders 4 can be operated to push the mounting seat 7 to the outside to operate the heat pump dryer body 6 normally. At the same time, after being pushed out, it is also convenient to disassemble the heat pump dryer body 6 from the top of the mounting seat 7.

[0039] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
