DETAILED DESCRIPTION

[0027] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0028] Embodiment 1

[0029] like Figure 1 As shown, the utility model proposes a steam drying system using a heat pump and electromagnetic heating, comprising: a heat pump system, a water storage tank 5, an electromagnetic steam generator 7, a gas-liquid separator 8 and a drying box 9;

[0030] The circulating water input end of the heat pump system is connected to the circulating water output end of the water storage tank 5, the circulating water output end of the heat pump system is connected to the circulating water input end of the electromagnetic steam generator 7, the steam output end of the electromagnetic steam generator 7 is connected to the drying box 9 through the gas-liquid separator 8, and the liquid output of the gas-liquid separator 8 is connected to the circulating water input end of the water storage tank 5 through a pipeline.

[0031] The COP of the heat pump system is very high. Compared with electric heating and other methods, the energy-saving effect of the heat pump system is very significant. Electromagnetic heating is electromagnetic induction heating. Compared with traditional resistance heating, electromagnetic heating not only has the advantage of high heat conversion efficiency, but also can achieve higher temperatures. The utility model heats the circulating water in the water storage tank through the heat pump system. The heated circulating water enters the electromagnetic steam generator to generate steam. The steam is separated into gas and liquid in the gas-liquid separator. The separated liquid is continuously input into the water storage tank as the source of circulating water in the heat pump system; the separated dry steam is passed into the drying box to dry the material.

[0032] As a further technical solution, a circulating water pump 6 is provided on the pipeline between the heat pump system and the water storage tank, and the circulating water pump 6 is used to pump circulating water into the heat pump system. The water storage tank is also provided with an inlet connected to an external water source for replenishing water to the water storage tank.

[0033] As a further technical solution, the heat pump system includes a box body, in which a compressor 1, an evaporator 2, a throttle valve 3 and a condenser 4 are arranged; the outlet of the evaporator 2 is connected to the inlet of the compressor 1 through a pipeline 10, the outlet of the compressor 1 is connected to the refrigerant inlet of the condenser 4 through a pipeline, the refrigerant outlet of the condenser 4 is connected to the inlet of the evaporator 2 through a pipeline, and a throttle valve 3 is also arranged on the pipeline between the refrigerant outlet of the condenser 4 and the inlet of the evaporator 2.

[0034] The circulating water inlet of the condenser 4 is communicated with the circulating water outlet of the water storage tank 5 , and the circulating water outlet of the condenser 4 is communicated with the inlet of the electromagnetic steam generator 7 .

[0035] The water in the water storage tank 5 is driven by the circulating water pump 6 and enters the condenser 4 in the heat pump system through the pipeline to absorb the heat released by the condensation of the refrigerant; the pipelines between the various components in the heat pump system can be selected as copper pipes, and the refrigerant condenses and releases heat in the condenser 4 through the copper pipes, providing heat for the water from the water storage tank 5 in the heat pump system. The heated water enters the electromagnetic steam generator 7 to generate steam, and the generated steam enters the gas-liquid separator 8 for gas-liquid separation. The liquid returns to the water storage tank 5 through the circulation pipeline, and the steam enters the drying box 9 to dry the material.

[0036] As a further technical solution, Figure 2 As shown, the drying box 9 is a rectangular box structure, the material of which can be stainless steel, including a drying box body 12, a steam inlet 11 is provided on the lower side of the drying box body 12, and the steam inlet 11 is connected to the steam outlet of the gas-liquid separator 8 through a pipeline; an exhaust port 14 is provided on the top of the drying box body 12, and a plurality of storage plates 13 arranged in sequence up and down are provided inside the drying box body 12, and the materials to be dried are placed on the storage plates 13.

[0037] Drying steam enters the interior of the drying box body 12 from the steam inlet 11 of the drying box, dries the materials on the placing plate 13, and then is discharged through the exhaust port 14 above.

[0038] As a further technical solution, Figure 3 As shown, the placing plate 13 is a porous plate, on which a plurality of through holes 15 are arranged in an array to facilitate the passage of drying steam.

[0039] The working principle of the utility model is:

[0040] After the compressor in the heat pump system is powered on, the refrigerant completes the heat pump cycle in the heat pump system; after the refrigerant reaches the condenser, it condenses and releases heat in it, heating the water from the water tank. The water in the water tank is driven by the circulating water pump and enters the condenser in the heat pump system to absorb the heat released by the condensation of the refrigerant. The water heated by the condensation heat enters the electromagnetic steam generator and is heated again to generate steam, but it contains liquid water. The steam generated by the electromagnetic steam generator enters the gas-liquid separator for gas-liquid separation, and the liquid water and steam are separated. The liquid water returns to the water tank for recycling, and the steam enters the drying box to dry the material.

[0041] Although the above describes the specific implementation methods of the utility model in combination with the accompanying drawings, it is not intended to limit the scope of protection of the utility model. Technical personnel in the relevant field should understand that on the basis of the technical solution of the utility model, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the scope of protection of the utility model.
