Description

Technical Field

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

[0002] In indoor drying equipment, a temperature regulating unit is usually used to adjust the outlet air temperature. The operating principle of this temperature regulating device is: a return air device is set up indoors to guide the air flow in the workshop to the inside of the equipment, and the air flow temperature is reduced by cooling. The condensation and dehumidification are carried out through the condensation equipment, and then the temperature is increased through the air conditioning system after compensation by the external air flow, and then it is guided to the room. This operation method is the most commonly used, but it has many technical problems, which are specifically reflected in: 1. Under normal circumstances, the temperature of the indoor return air is relatively high, and the temperature difference between this part of the air flow and the indoor supply air temperature is not very large. It is just that there is a large amount of moisture in the return air flow. When the existing equipment discharges moisture in the air flow, it must first reduce the return air temperature. This measure causes part of the return air heat to be wasted, and the energy loss is serious; 2. The existing equipment of this type needs to supplement the external exhaust air flow, that is, it needs to extract outdoor air. Because the temperature of the outdoor air is relatively low, it needs to be heated when supplying air to the room. This heating leads to increased energy loss and increased equipment operation costs.

[0003] In view of the above-mentioned drawbacks, as technical workers in this field, the technical problem that needs to be solved is: to design a special air-energy heat pump dryer, which can effectively preserve the air flow temperature in the return air through a novel air-conditioning structure design and conduct it to the room as basic heat, while removing the outdoor exhaust structure to realize the circulation of indoor air flow and avoid indoor pollution and energy loss caused by external air flow circulation.

DETAILED DESCRIPTION

[0025] The present invention is further described below through implementation methods. It should be understood that the following embodiments are only for illustrative purposes, and those skilled in the art may make further extensions based on the following explanations. Such technical extensions should fall within the scope of protection of the claims of this patent.

[0026] As shown in the accompanying drawings, an air energy heat pump dryer includes a cabinet 1, a support frame 2 is arranged inside the cabinet 1, and the support frame 2 is divided into multiple chambers by partitions. In this embodiment, the cabinet 1 is a sealed chamber, and a return air port 11 is arranged on its outer wall, which guides air into a return air chamber 18 through the return air port 11. The return air chamber 18 is arranged on the upper part of the support frame 2.

[0027] The support frame 2 includes a plurality of chambers, including a central heat exchange chamber 3, an evaporator fixed chamber 4, a compression chamber 6, a condenser fixed chamber 7, and a fan chamber 8.

[0028] The middle heat exchange bin 3 is located in the middle area, one side of the middle heat exchange bin 3 is connected to the return air port 11 and the return air bin 18, and a total heat exchanger 31 is arranged in the middle heat exchange bin 3, and the total heat exchanger is provided with cross-arranged heat exchange chambers, and its specific structure is as follows Figure 4As shown, this total heat exchanger 31 is a square structure, which includes two side plates 311, a fixed frame 312 and a connecting rod are arranged between the two side plates 311, and a plurality of partitions 313 are arranged between the two side plates 311. The cross-penetration is achieved through the sealing combination between the partitions 313. The cross-penetration includes a transverse through hole 315 and a vertical through hole 314. The transverse through hole 315 and the vertical through hole 314 are the heat exchange chambers arranged at intervals and crosses. The vertical through hole 314 penetrates the return air port 11 and the evaporator fixed chamber 4; the transverse through hole 315 penetrates the compression chamber 6 and the condenser fixed chamber 7. Through this structural setting, the indoor return air flow can be cooled through the total heat exchanger 31 after entering the equipment at the return air port 11. This energy reduction is directly converted to the air flow moving from the compression chamber 6 to the condenser fixed chamber 7.

[0029] The evaporator fixed bin 4 is provided with an evaporator 41, the compression chamber 6 is provided with a compressor 61, the condenser fixed bin 7 is provided with a condenser 71, and the fan bin 8 is provided with a fan 81. A guide bin 5 and a corner bin 9 are provided between the evaporator fixed bin 4 and the compression chamber 6, and a guide plate 51 is provided in the guide bin 5, and the guide plate 51 cooperates with the corner bin 9 to realize right-angle guidance of airflow.

[0030] The working principle of the utility model is as follows Figure 5 As shown, the indoor return air enters the return air bin 18 through the return air port 11, and the return air bin 18 is connected and connected with the vertical through hole 314 in the middle heat exchange bin 3. After cooling and heat exchange through the total heat exchanger 31, the air flow temperature is reduced and enters the evaporator 41 in the evaporator fixed bin 4 for condensation and dehumidification. The evaporator fixed bin 4 is provided with an external pipe 42, and the condensed liquid is guided outward through the external pipe 42. After the dehumidified air flow passes through the compression chamber 6, it is heated through the horizontal through hole 315 in the middle heat exchange bin 3. The heat source consumed for the heating comes from the return air flow temperature. After the temperature is raised to the base temperature, the condenser 7 in the condenser fixed bin 7 is heated for the second time. After the second heating, the fan 81 is pressurized to realize indoor air supply. The evaporator 41, compressor 61, and condenser 71 described above are connected through management to form an air conditioning system. This connection is a common technology in the field of air conditioning and will not be described in detail here. The utility model retains the initial temperature of the air return air to the maximum extent during the process of air flow cooling, dehumidification and heating, thereby reducing energy consumption.

[0031] Furthermore, in winter when the temperature is relatively cold, a relatively stable heat source supply cannot be achieved only through the condenser 71, so the device is also provided with a heating device between the condenser fixed compartment 7 and the fan compartment 8, and the heating device is an electric heater or a fuel heating device or a solar heating device. This embodiment discloses an electric heating device 72, and its specific structure is: it includes a support frame, and a plurality of electric heating tubes are arranged inside the support frame.

The air supply port is arranged at the bottom of the room. Since the air flow is in operation, the hot air flow rises, and the indoor moisture can be adsorbed and discharged during the rising process.

[0033] like Figure 2 As shown, the outer wall of the cabinet 1 is provided with an exchanger replacement port 12, and the exchanger replacement port 12 is provided with a compartment door, which is arranged on the outer wall of the middle heat exchange compartment 3, so as to realize the maintenance and replacement of the internal full heat exchanger 31. The outer wall of the cabinet 1 is provided with a maintenance port 13 and a fan maintenance port 14, the maintenance port 13 is arranged on the outer wall of the compression chamber 6, and the fan maintenance port 14 is arranged in the fan compartment 8, and the internal compressor 61 or the fan 81 can be inspected and maintained through the maintenance port 13 and the fan maintenance port 14 respectively.
