Description

Technical Field

[0001] The present invention belongs to the technical field of heat pump drying, and specifically refers to a drying device based on an air source heat pump. Background Art

[0002] The air source heat pump drying technology is an efficient, energy-saving and environmentally friendly drying method, which is widely used in the fields of food, agricultural products, Chinese herbal medicines, seafood, wood, industrial products, etc. Its core principle is based on the reverse Carnot cycle. By absorbing the low-grade heat energy in the air, it is lifted to high-temperature heat energy through the work of the compressor and used to dry materials.

[0003] Currently, the existing drying devices based on air source heat pumps have the following problems: When the existing drying device based on an air source heat pump is restarted after the air source heat pump is shut down, its heating rate will become slower, especially in a low-temperature environment (such as winter), which causes a large amount of low-temperature gas to flow into the heated drying chamber, affecting the temperature inside the heated drying chamber. Moreover, the traditional drying device based on an air source heat pump does not have the ability to assist in heating the medium-temperature hot air, thereby prolonging the rising time of the hot air temperature generated during the initial operation of the air source heat pump, resulting in waste of some heat generated by the air source heat pump. Therefore, it cannot meet the current usage requirements of drying devices based on air source heat pumps. Summary of the Invention

[0004] In view of the above situation, in order to overcome the defects of the prior art, this solution provides a drying device based on an air source heat pump that can block the inflow of low-temperature gas into the drying chamber, ensure the temperature inside the heated drying chamber, and can assist in heating the hot air during the temperature rising stage, shortening the rising time of the hot air temperature during the initial operation of the heat pump.

[0005] The technical solution adopted by this solution is as follows: A drying device based on an air source heat pump proposed by this solution includes a heat dissipation box, a heat dissipation fan, an air source heat pump, a diversion component, a temperature sensing component, a closing component, and a pressure relief component. The heat dissipation fans are symmetrically arranged on the inner walls at both ends of the heat dissipation box. The air source heat pump is arranged inside the heat dissipation box. The diversion component is arranged on one side of the heat dissipation box. The temperature sensing component includes a sliding component, an energy storage component, a temperature measuring component, and an energy absorbing component. The sliding component is arranged on the inner wall of the diversion component away from the heat dissipation box. The energy storage component is arranged inside the sliding component. The temperature measuring component is arranged at the end of the sliding component away from the energy storage component. The energy absorbing components are respectively arranged on the energy storage component and the temperature measuring component. The closing component is arranged on the inner wall of one end of the diversion component. The pressure relief component is arranged at the end of the diversion component close to the heat dissipation box.

[0006] As a further optimization of the solution in this case, the diversion assembly includes a diversion frame, a conical air delivery cylinder, and a drying cylinder. The diversion frame is symmetrically arranged on one side of the heat dissipation box. The conical air delivery cylinder is arranged between the diversion frame and the heat dissipation box. The hot gas end of the air source heat pump penetrates through the heat dissipation box and is communicated with the conical air delivery cylinder. The drying cylinder is communicated and arranged on the side of the conical air delivery cylinder away from the heat dissipation box.

[0007] During use, the hot gas generated by the air source heat pump flows into the conical air delivery cylinder. The conical air delivery cylinder discharges the hot gas into the drying chamber through the drying cylinder to perform drying operations on the materials.

[0008] Preferably, the sliding assembly includes a sliding frame, a heat preservation cylinder, and a conical sliding cylinder. The sliding frame is slidably arranged on the inner wall of the end of the conical air delivery cylinder away from the heat dissipation box. The heat preservation cylinder is arranged on the inner wall of the sliding frame. The conical sliding cylinder is communicated and arranged on the side of the heat preservation cylinder away from the sliding frame. The energy storage assembly includes a heat insulation plate and an energy storage copper block. The energy storage copper block is slidably arranged inside the heat preservation cylinder. The heat insulation plate is arranged on the side of the energy storage copper block close to the conical sliding cylinder, and the heat insulation plate is attached to the inner wall of the conical sliding cylinder. The temperature measurement assembly includes a windward copper column, a temperature sensor, a temperature measurement end, a temperature measurement copper rod, and a copper spring. The windward copper column penetrates through and is arranged on the inner wall of the end of the conical sliding cylinder away from the heat preservation cylinder. The temperature sensor is arranged on the side wall of the heat dissipation box. Multiple groups of the temperature measurement ends are arranged on the side of the heat insulation plate away from the heat preservation cylinder. The temperature sensor is electrically connected to the temperature measurement ends. Multiple groups of the temperature measurement copper rods are arranged on the side wall of the heat insulation plate. The copper spring is arranged between the temperature measurement copper rod and the windward copper column, and the temperature measurement end is connected to the temperature measurement copper rod. The energy absorption assembly includes an energy absorption electromagnet and an energy storage magnet. The energy absorption electromagnet is arranged on the side of the temperature measurement copper rod close to the heat insulation plate. The energy storage magnet is arranged on the side of the heat insulation plate close to the energy absorption electromagnet. The energy absorption electromagnet and the energy storage magnet are arranged opposite to each other.

[0009] During use, the copper spring is normally set to be elongated. The energy storage copper block is located inside the heat preservation cylinder. The heat insulation plate is attached to the inner wall of the conical sliding cylinder. The hot gas generated by the air source heat pump enters the conical air delivery cylinder and impacts the windward copper column. After being heated by the hot gas, the temperature of the windward copper column rises. The windward copper column heats the inside of the conical sliding cylinder, and the windward copper column heats the temperature measurement copper rod through the copper spring. The temperature sensor detects the temperature of the temperature measurement copper rod through the temperature measurement end. When the hot gas generated by the air source heat pump meets the requirements of the operator, the energy absorption electromagnet is energized to generate magnetism. The energy absorption electromagnet and the energy storage magnet are arranged with opposite polarities. The energy absorption electromagnet is fixed on the side wall of the temperature measurement copper rod and adsorbs the energy storage magnet through magnetic force. The energy storage magnet drives the heat insulation plate away from the heat preservation cylinder by deforming the copper spring. The heat insulation plate drives the energy storage copper block to extend out of the heat preservation cylinder. At this time, the energy storage copper block comes into contact with the hot air inside the conical sliding cylinder, and the energy storage copper block is heated.

[0010] Specifically, the closing assembly includes a closing spring, a closing magnet, and an adjustable-distance electromagnet. The closing spring is disposed between the inner wall of the heat preservation cylinder and the inner wall of the conical air delivery cylinder. The closing magnet is disposed on the side wall of the heat preservation cylinder outside the closing spring. The adjustable-distance electromagnet is disposed on the inner wall of the conical sliding cylinder outside the closing spring. The closing magnet and the adjustable-distance electromagnet are arranged opposite to each other.

[0011] During use, the normal state of the closing spring is set to be shortened. The distance between the inner wall of the conical air delivery cylinder and the side wall of the conical sliding cylinder is the maximum value. The hot air generated by the air source heat pump flows out through the distance between the conical air delivery cylinder and the conical sliding cylinder. When used in a low-temperature environment, since the heat in the air decreases, the heat absorbed by the air source heat pump from the air also decreases correspondingly, resulting in a slower heating rate. When the hot air generated by the air source heat pump impacts the windward copper column, the temperature measuring sensor detects the temperature of the windward copper column through the temperature measuring end. When the temperature of the hot air does not meet the requirements of the operator, the adjustable-distance electromagnet is energized to generate magnetism. The closing magnet and the adjustable-distance electromagnet are set with the same poles. The adjustable-distance electromagnet is fixed on the inner wall of the conical sliding cylinder. The adjustable-distance electromagnet uses the deformation of the closing spring to push the closing magnet through repulsive force. The closing magnet drives the conical sliding cylinder to approach the inclined inner wall of the conical air delivery cylinder through the heat preservation cylinder. The side wall of the conical sliding cylinder fits against the inner wall of the conical air delivery cylinder. The gas that does not reach the temperature control standard cannot flow into the drying chamber through the conical air delivery cylinder.

[0012] Among them, the pressure relief assembly includes an electric valve, a pipe clamp, and a low-temperature pipe. The electric valves are symmetrically arranged on the upper wall and the bottom wall of the conical air delivery cylinder near one end of the heat dissipation box. The electric valves are communicated with the conical air delivery cylinder. The pipe clamps are symmetrically arranged on the upper wall and the bottom wall of the conical air delivery cylinder far from one end of the heat dissipation box. The low-temperature pipe is communicated and arranged between the electric valve and the pipe clamp.

[0013] During use, the hot air generated by the air source heat pump that does not meet the requirements of the operator remains at one end of the conical air delivery cylinder near the heat dissipation box. The electric valve is turned on, and the gas that does not reach the temperature control standard inside the conical air delivery cylinder is discharged through the low-temperature pipe.

[0014] Preferably, a controller is provided on the side wall of the heat dissipation box.

[0015] Furthermore, the controller is electrically connected to the cooling fan, the air source heat pump, the temperature measuring sensor, the energy absorption electromagnet, the adjustable-distance electromagnet, and the electric valve respectively.

[0016] The beneficial effects obtained by adopting the above structure are as follows: Compared with the prior art, this solution combines a thermal energy monitoring structure and a thermal energy storage structure. Through the set diversion component, temperature sensing component, closing component and pressure relief component, and with the mutual cooperation of the sliding component, energy storage component, temperature measuring component and energy absorption component, it can monitor the hot gas temperature generated by the air source heat pump during shutdown and restart. Utilizing the distance between the conical air delivery cylinder and the conical sliding cylinder, it reduces the probability of low-temperature gas entering the drying chamber, enables the hot gas that meets the operation requirements to be released into the drying chamber, ensures the operation temperature inside the drying chamber, and uses the energy storage copper block to store the heat in the hot gas through physical adsorption or heat conduction, facilitating the heating of low-temperature hot gas and reducing the waste of heat in the low-temperature hot gas, thereby improving the use efficiency of the air source heat pump in the drying operation to a certain extent.

[0027] A controller 33 is arranged on the side wall of the heat dissipation box 1.

[0028] The controller 33 is electrically connected to the heat dissipation fan 2, the air source heat pump 3, the temperature measuring sensor 20, the energy absorption electromagnet 16, the adjustable-distance electromagnet 27, and the electric valve 29 respectively.

[0029] During specific use, the copper spring 23 is normally in an extended state. The energy storage copper block 15 is located inside the heat preservation cylinder 11. The heat insulation plate 14 is attached to the inner wall of the conical sliding cylinder 12. The closing spring 25 is normally in a shortened state. The distance between the inner wall of the conical air delivery cylinder 6 and the side wall of the conical sliding cylinder 12 is at the maximum value. The drying cylinder 7 is communicated with the drying chamber, and the material to be dried is placed inside the drying chamber. The controller 33 controls the heat dissipation fan 2 and the air source heat pump 3 to start. The heat dissipation fan 2 dissipates the heat generated during the operation of the air source heat pump 3 inside the heat dissipation box 1. The hot air generated by the air source heat pump 3 flows into the conical air delivery cylinder 6. The hot air generated by the air source heat pump 3 enters the conical air delivery cylinder 6 and impacts the windward copper column 19. After being heated by the hot air, the temperature of the windward copper column 19 rises. The windward copper column 19 heats the inside of the conical sliding cylinder 12, and the windward copper column 19 heats the temperature measuring copper rod 22 through the copper spring 23. The controller 33 controls the temperature measuring sensor 20 to start. The temperature measuring sensor 20 detects the temperature of the temperature measuring copper rod 22 through the temperature measuring end 21. When the hot air generated by the air source heat pump 3 meets the requirements of the operator, the controller 33 controls the energy absorption electromagnet 16 to start. The energy absorption electromagnet 16 is energized to generate magnetism. The energy absorption electromagnet 16 and the energy storage magnet 17 are arranged with opposite polarities. The controller 33 controls the current flowing into the energy absorption electromagnet 16 to increase. The energy absorption electromagnet 16 is fixed on the side wall of the temperature measuring copper rod 22 and adsorbs the energy storage magnet 17 by magnetic force. The energy storage magnet 17 drives the heat insulation plate 14 away from the heat preservation cylinder 11 by the deformation of the copper spring 23. The heat insulation plate 14 drives the energy storage copper block 15 to extend out of the heat preservation cylinder 11. At this time, the energy storage copper block 15 contacts the hot air inside the conical sliding cylinder 12 and is heated. The hot air generated by the air source heat pump 3 flows out through the gap between the conical air delivery cylinder 6 and the conical sliding cylinder 12. The conical air delivery cylinder 6 discharges the hot air into the drying chamber through the drying cylinder 7 to perform drying operation on the materials. After the materials inside the drying chamber are dried, the controller 33 controls the air source heat pump 3 to stop. After the operator takes out the materials inside the drying chamber and puts in new materials, the controller 33 controls the air source heat pump 3 to start, and the air source heat pump 3 conveys hot air into the drying chamber again. When the air source heat pump 3 is turned on after being turned off, its heating rate will slow down, causing a large amount of low-temperature gas to flow into the drying chamber, thereby reducing the temperature inside the drying chamber. When the low-temperature gas impacts the windward copper column 19, the temperature of the windward copper column 19 will gradually decrease. At this time, the controller 33 controls the energy absorption electromagnet 16 to be powered off and demagnetized. The copper spring 23 deforms and resets. The heat insulation plate 14 drives the energy storage copper block 15 to retract into the heat preservation cylinder 11. The heat insulation plate 14 fits against the inner wall of the conical sliding cylinder 12. The heat preservation cylinder 11 changes from an open state to a sealed state, and the heat adsorbed inside the energy storage copper block 15 is preserved inside the heat preservation cylinder 11. The controller 33 controls the start of the distance-adjusting electromagnet 27, and the distance-adjusting electromagnet 27 is energized to generate magnetism. The closing magnet 26 is arranged with the same pole as the distance-adjusting electromagnet 27, and the distance-adjusting electromagnet 27 is fixed on the inner wall of the conical sliding cylinder 12. The internal current of the distance-adjusting electromagnet 27 increases, and the deformation of the closing spring 25 is utilized to push the closing magnet 26 through the repulsive force. The closing magnet 26 drives the conical sliding cylinder 12 to approach the inclined inner wall of the conical gas delivery cylinder 6 through the heat preservation cylinder 11. The side wall of the conical sliding cylinder 12 fits with the inner wall of the conical gas delivery cylinder 6, and the low-temperature gas in a relatively low state cannot flow into the drying chamber through the conical gas delivery cylinder 6. The gas generated by the air-energy heat pump 3 that does not meet the temperature control standard is retained at one end of the conical gas delivery cylinder 6 close to the heat dissipation box 1. The controller 33 controls the start of the electric valve 29, and the electric valve 29 is turned on. The hot gas that does not meet the requirements inside the conical gas delivery cylinder 6 is discharged through the low-temperature pipe 31. When the low-temperature hot air gradually rises and leaves the lower low-temperature state, the controller 33 controls the energy-absorbing electromagnet 16 to start, and the current inside the energy-absorbing electromagnet 16 increases. The energy-absorbing electromagnet 16 attracts the energy-storage magnet 17 through magnetic force, and the energy-storage magnet 17 uses the deformation of the copper spring 23 to drive the heat insulation board 14 away from the inside of the conical sliding cylinder 12. The energy-storage copper block 15 extends from the inside of the insulation cylinder 11 again, and the energy-storage copper block 15 heats the air inside the conical sliding cylinder 12. The conical sliding cylinder 12 uses the windward copper column 19 to assist in heating the medium-temperature gas in the temperature rising stage, thereby reducing the probability of the hot air temperature inside the drying chamber dropping, thereby overcoming the problem that the air-energy heat pump 3 is turned on after being turned off, and its heating speed will slow down, causing a large amount of low-temperature gas to enter the drying chamber. Repeat the above operation when using it next time.
