Description

Technical Field

[0001] This utility model relates to the field of drying equipment technology, specifically to a heat pump coupled dehumidification and drying system. Background Technology

[0002] In fields such as agricultural product processing, food preservation, and wood treatment, the drying of materials is a key step in ensuring product quality and extending the storage period. Traditional drying technologies often rely on methods such as direct hot air blowing and natural sun drying, which have problems such as high energy consumption, long drying cycles, and great susceptibility to environmental influences. However, with the development of energy-saving technologies, heat pump technology has been gradually applied to dehumidification and drying systems due to its advantages such as high energy efficiency ratio and precise temperature control. By collecting external gas through a heat pump, heating it, and then passing it into the drying chamber, the hot air flow is used to remove the moisture from the materials, achieving low-energy drying.

[0003] However, existing heat pump coupled dehumidification and drying systems have certain problems in actual operation:

[0004] The external gas collected by the heat pump often contains a certain amount of water vapor. After the heated airflow enters the drying chamber, this water vapor will come into direct contact with the material to be dried. The mixing of water vapor increases the ambient humidity inside the drying chamber, weakens the ability of the hot airflow to adsorb moisture from the material, and slows down the dehydration speed of the material, seriously reducing the drying efficiency of the system.

[0005] Therefore, we propose a heat pump coupled dehumidification and drying system to solve the above problems. Utility Model Content

[0006] In view of the problems existing in the above-mentioned heat pump coupled dehumidification and drying system, this utility model is proposed.

[0007] Therefore, the purpose of this utility model is to provide a heat pump coupled dehumidification and drying system, which solves the problem that when existing heat pump drying equipment collects external airflow for heating, the water vapor in the airflow cannot be effectively treated, which affects the rapid drying of subsequent materials.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A heat pump coupled dehumidification and drying system includes a heat pump assembly and a drying chamber. A recovery pipe is connected between the heat pump assembly and the lower end of the drying chamber. A heat conduction pipe is connected to the air outlet of the heat pump assembly. A plurality of spaced branch pipes are connected to the wall of the heat conduction pipe. Each branch pipe passes through the drying chamber and is fitted with a dehumidification pipe.

[0010] The lower end of the dehumidification tube is filled with moisture-absorbing cotton, and the lower end of the moisture-absorbing cotton is located inside the dehumidification tube and is provided with a material picking and replacing component for pushing the moisture-absorbing cotton to move.

[0011] Preferably, the material handling and replacement assembly includes a pusher plate. The wall of the dehumidification tube has two symmetrically arranged rotating holes. A crossbar is fixedly installed in the rotating holes. The pusher plate is rotatably sleeved on the outside of the crossbar, with its lower end located inside the dehumidification tube. A torsion spring is sleeved on the wall of the crossbar. The two ends of the torsion spring are fixedly connected to the crossbar and the pusher plate, respectively. The inner wall of the rotating holes has two symmetrically arranged grooves, and the torsion spring is located in the grooves.

[0012] Preferably, a rubber sealing sleeve is fixedly fitted on the upper end of the pusher plate, and the opening of the rubber sealing sleeve is fitted outside the rotating hole and fixedly connected to the wall of the dehumidification pipe.

[0013] Preferably, each of the branch pipes has a connecting thread at the lower end of its outer wall, and the dehumidification pipe is an internally threaded pipe, which is threaded onto the outside of the branch pipe.

[0014] Furthermore, the bottom of the dehumidification tube is provided with multiple spaced-apart breathable filter holes.

[0015] Preferably, all of the pusher plates are arranged in an L-shape, and adjacent pusher plates are staggered front to back.

[0017] 1. This utility model, through the provided heat pump component, drying chamber, heat conduction pipe, branch pipe, dehumidification pipe and moisture-absorbing cotton, can stably transfer heat flow to the drying chamber through the heat pump component to fully dry the material.

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] This utility model discloses a heat pump coupled dehumidification and drying system.

[0027] This utility model provides, for example Figure 1-3 The heat pump coupled dehumidification and drying system shown includes a heat pump assembly 1 and a drying chamber 2. A recovery pipe 3 is connected between the lower end of the heat pump assembly 1 and the drying chamber 2. A heat conduction pipe 4 is connected to the air outlet end of the heat pump assembly 1. A plurality of spaced branch pipes 5 are connected to the wall of the heat conduction pipe 4. Each branch pipe 5 passes through the drying chamber 2 and is fitted with a dehumidification pipe 6. The lower end of the outer wall of each branch pipe 5 is provided with a connecting thread. The dehumidification pipe 6 is an internally threaded pipe and is threaded onto the outside of the branch pipe 5.

[0028] To facilitate quick removal and replacement of absorbent cotton after prolonged use, such as Figure 2-3 As shown, the lower end of the dehumidification pipe 6 is filled with absorbent cotton 7. The lower end of the absorbent cotton 7 is located inside the dehumidification pipe 6 and is equipped with a material picking and replacement component for pushing the absorbent cotton 7 to move. The material picking and replacement component includes a pusher plate 8. The pipe wall of the dehumidification pipe 6 has two symmetrically arranged rotating holes 9. A crossbar 10 is fixedly installed inside the rotating holes 9. The pusher plate 8 is rotatably sleeved on the outside of the crossbar 10, and its lower end is located inside the dehumidification pipe 6. A rubber sealing sleeve 12 is fixedly sleeved on the upper end of the pusher plate 8. The opening of the rubber sealing sleeve 12 is sleeved on the outside of the rotating holes 9 and is fixedly connected to the pipe wall of the dehumidification pipe 6. A torsion spring 11 is sleeved on the wall of the crossbar 10. The two ends of the torsion spring 11 are fixedly connected to the crossbar 10 and the pusher plate 8, respectively. The inner wall of the rotating holes 9 has two symmetrically arranged grooves 14. The torsion spring 11 is located in the grooves 14. The multiple pusher plates 8 are all arranged in an L-shape, and the two adjacent pusher plates 8 are staggered front and back.

[0029] Working principle: During operation, the hot air generated by the heat pump component 1 is delivered to each branch pipe 5 through the heat pipe 4. The hot air enters the dehumidification pipe 6 through the branch pipe 5. The moisture-absorbing cotton 7 in the dehumidification pipe 6 absorbs the moisture in the hot air. The dry hot air after removing the moisture enters the drying chamber 2 through the air vent 13 at the bottom of the dehumidification pipe 6 to dry the materials in the chamber.

[0030] The hot and humid airflow generated during the drying process flows back to the heat pump assembly 1 through the recovery pipe 3 to achieve heat recycling. When it is necessary to replace the absorbent cotton 7, first unscrew the dehumidification pipe 6 from the branch pipe 5 (using the connecting thread on the outer wall of the branch pipe 5 to engage with the internal thread of the dehumidification pipe 6), press the upper end of the pusher plate 8, the pusher plate 8 rotates around the crossbar 10, and its lower end tilts upward, pushing the absorbent cotton 7 out of the dehumidification pipe 6. At this time, the torsion spring 11 is twisted and stored. After releasing the pusher plate 8, the torsion spring 11 drives the pusher plate 8 to reset under its own elastic force. The rubber sealing sleeve 12 can prevent airflow from leaking from the rotating hole 9, and the groove 14 provides deformation space for the torsion spring 11. After replacing the new absorbent cotton 7, the dehumidification pipe 6 can be reinstalled on the branch pipe 5 for continued use. The adjacent pusher plates 8 are staggered to avoid mutual interference during operation.

[0031] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
