Description

Technical Field

[0001] The utility model relates to the technical field of heat pump drying equipment, in particular to an energy-saving heat pump drying system. Background Art

[0002] As we all know, the energy-saving heat pump drying system is a highly efficient and environmentally friendly drying equipment. It uses heat pump technology to achieve low-temperature drying and has the advantages of energy saving, environmental protection, and high efficiency. The system is mainly composed of a compressor, a condenser, an expansion valve, and an evaporator. Its working principle is to compress the low-temperature and low-pressure refrigerant into a high-temperature and high-pressure refrigerant through a compressor, and then transport it to the condenser for heat release, so that the air temperature increases, thereby achieving the purpose of drying.

[0003] The existing energy-saving drying system lacks an automatic ejection function. After drying is completed, the temperature of the dried items is too high, and workers are easily scalded when replacing them. In this way, the drying rack in the drying box cannot be automatically ejected, which will lead to low work efficiency, increased labor costs, safety hazards, unstable drying quality, high work intensity, and reduced equipment utilization. Therefore, in order to improve drying efficiency and ensure drying quality, an energy-saving heat pump drying system is proposed. Utility Model Content

In this embodiment, after the drying work in the drying box 1 is completed, the sealing door 4 is opened, and the driving motor 7 is started. The output end of the driving motor 7 drives the bidirectional screw 6 to rotate, and the bidirectional screw 6 drives the sliders 8 at both ends to move closer to each other. Under the action of the connecting rod 9, the push plate 10 is away from the bidirectional screw 6 to push the drying rack 2 to move outward. The drying rack 2 is moved to the trolley prepared outside the drying box 1 under the action of the pulley 5, and then a new drying rack 2 is replaced to continue the next drying work. The automatically pushed drying rack 2 can reduce the steps of manual operation, thereby speeding up the processing speed of the dried items and improving the overall work efficiency. There is no need for workers to manually take out the dried items, which reduces manpower input and reduces labor costs. The automatically pushed drying rack 2 can more effectively utilize the space of the drying box 1, reduce equipment idle time, and improve equipment utilization.

[0027] In actual use, in order to further prevent the drying rack 2 from deviating from its motion trajectory during the pushing process, in this embodiment, two sets of slide grooves 12 are provided on the bottom wall of the inner cavity of the drying box 1, and the slide grooves 12 are adapted to the pulley 5. The pushing plate 10 pushes the drying rack 2 outward during the movement, and the pulley 5 moves along the direction of the slide grooves 12 during the movement, which guides the movement of the drying rack 2 and prevents the drying rack 2 from deviating from its motion trajectory.

[0028] In actual use, in order to further prevent the drying rack 2 from moving during the drying process, in this embodiment, a fixed block 13 is installed on the back side of the drying rack 2, and an electromagnetic plate 14 is installed on the pushing plate 10. The electromagnetic plate 14 is magnetically connected to the fixed block 13. When the electromagnetic plate 14 is energized, the electromagnetic plate 14 can fix the drying rack 2 in the inner cavity of the drying box 1 through the magnetic connection with the fixed block 13, thereby preventing the drying rack 2 from moving during the drying process.

[0029] In actual use, in order to further facilitate the movement of the drying box 1, in this embodiment, the moving device includes universal wheels 15 and a brake assembly 16. The universal wheels 15 are installed at the four corners of the bottom end of the drying box 1, and the brake assembly 16 is provided on the universal wheels 15.

The universal wheels 15 facilitate moving the drying box 1 to the target position, and the brake assembly 16 is used to fix the drying box 1.

[0030] In actual use, it is further convenient to cooperate with the mobile device to control the moving direction of the drying box 1. In this embodiment, a push handle 17 is installed on the right side wall of the drying box 1. The combination of the push handle 17 and the mobile device makes the movement of the drying box 1 more convenient. The push handle 17 provides a convenient grip and operation point for the staff, so that the staff can easily push or move the drying box 1.

[0031] In actual use, in order to further facilitate opening and closing of the sealing door 4 , in this embodiment, a handle 18 is installed on the sealing door 4 , and the handle 18 further facilitates opening and closing of the sealing door 4 .

[0032] In actual use, the safety of the handle 18 and the push handle 17 is further improved. In the present embodiment, the handle 18 and the push handle 17 are provided with anti-slip grooves. The design of the anti-slip grooves can significantly increase the friction on the surface of the push handle 17 and the handle 18. The increased friction helps to prevent the push handle 17 and the handle 18 from slipping in the hand when the hand sweat or water stains appear during use, thereby improving the safety of use.

[0033] In actual use, the stability and accuracy of the operation of the drive motor 7 are further guaranteed. In this embodiment, the drive motor 7 is a servo motor. The servo motor can control the position, speed and torque with high precision. The servo motor adopts closed-loop control and has good stability.
