[0038] In some embodiments of the present application, a drying device is provided, comprising:
[0039] The heating module is used to provide heat to ensure the air supply temperature of the drying airflow for the volatile oil on the fins, and includes:
[0040] A housing 100 , on which an air return portion 110 and an air outlet portion are formed;
[0041] In some embodiments, the shell 100 is a stainless steel shell. To improve the thermal insulation of the shell 100 , a hollow layer is formed inside the shell 100 , and the hollow layer is filled with thermal insulation materials.
[0042] The thermal insulation material is thermal insulation foam or thermal insulation foam.
[0043] In some embodiments, a thermal insulation material is attached to the inner wall of the shell 100 or a thermal insulation material is attached to the outer wall of the shell 100 to achieve thermal insulation of the shell 100 .
[0044] The air return portion 110 is used to introduce air flow into the interior of the housing 100 . The structure of the air return portion 110 may be a return air port or a plurality of return air holes.
[0045] The air outlet portion is used to guide the airflow out of the housing 100 , and is an air outlet or air outlet hole opened on the housing 100 .
[0046] The condenser module 200 is arranged inside the shell 100, and is connected with the compressor 310, the evaporator 320 and the throttling device 330 to form a compressor unit. When the compressor unit is running, it exchanges heat with the air flow flowing into the shell 100.
[0047] The compressor 310, the condenser module 200, the evaporator 320, and the throttling device 330, i.e., the main electronic expansion valve, are connected through a refrigerant pipeline to form a refrigeration cycle loop, and the refrigerant flows inside the refrigeration cycle loop to perform corresponding cooling or heating operations.
[0048] In some embodiments of the present application, a balancing tank 340 , an economizer 350 , and a main electronic expansion valve are connected to the refrigerant pipelines of the condenser module 200 and the evaporator 320 .
[0049] A refrigerant branch pipe is connected between the main electronic expansion valve and the economizer 350 , and an auxiliary electronic expansion valve 360 is connected to the refrigerant branch pipe.
[0050] The refrigerant using R245fa is compressed by the high-temperature compressor 310 and becomes a high-temperature and high-pressure gas. The high-temperature and high-pressure exhaust gas enters the condenser module 200 for heat release and condensation, and is condensed into a medium-temperature and high-pressure liquid. The balance tank 340 is used to balance the refrigerant of the relevant system; the main refrigerant is throttled and cooled by the economizer 350 and the auxiliary electronic expansion valve 360, and then the system refrigerant quantity, exhaust gas temperature, etc. are adjusted by the main electronic expansion valve. At the same time, the main refrigerant is throttled and cooled and then enters the evaporator 320 for evaporation and heat absorption; the low-temperature and low-pressure refrigerant after heat absorption enters the gas-liquid separator for gas-liquid separation, and the refrigerant with a certain dryness is sucked into the compressor 310 for intake, and then circulated for compression and exhaust, thereby completing the entire refrigerant circulation system.
[0051] The refrigerant flowing through the condenser module 200 can perform heat exchange with the airflow inside the housing 100 when entering the condenser module 200 , thereby heating the internal airflow and increasing its temperature.
[0052] By cooperating with the compressor unit and the condenser module 200, when the compressor unit starts to operate, the refrigerant flowing through the condenser module 200 exchanges heat with the air inside the shell 100 to heat the airflow. The condenser module 200 replaces the combustion chamber in the existing drying furnace. The airflow is heated by heat exchange with the refrigerant, so that the heating of the airflow does not need to be achieved by burning fuel gas, which reduces energy consumption, avoids the discharge of pollutants to the outside, and achieves the effect of energy saving and emission reduction.
[0053] The heating air duct 400 is connected to the air outlet of the housing 100 and is used for circulating the air flow that has passed through the condenser module 200 for heat exchange. The heating air duct 400 has an air duct outlet 410 for outputting the air flow of the heating air duct 400.
[0054] The airflow that has exchanged heat in the condenser module 200 can be transported outward through the heating air duct 400 and output through the air duct output portion.
[0055] During setting, the air duct outlet 410 is set to face the object to be dried to ensure that the airflow can be blown directly onto the object to be dried, thereby ensuring the drying effect.
[0056] The main air supply device 500 is connected to the heating air duct 400, and can at least drive the air flow to flow between the return air portion 110, the housing 100, the heating air duct 400, and the air duct outlet portion 410 to dry the items to be dried.
[0057] In some embodiments, the main air supply device 500 is a main fan, which is used to provide air circulation flow power.
[0058] A main air flow channel is formed between the return air portion 110, the housing 100, the heating air duct 400 and the air duct outlet portion 410, and the main air supply device 500 is used to drive the air flow in the main air flow channel to dry the parts to be dried.
[0059] For the convenience of description, the following takes the drying of volatile oil on the fins of a heat exchanger as an example.
[0060] When the main fan is running, it can at least suck in the air flow from the return air part 110 on the shell 100, and then flow through the condenser module 200 inside the shell. The air flow is heated after heat exchange in the condenser module 200, and circulates through the heating air duct 400 after heating, and then is transported to the heat exchanger fins through the air duct outlet 410 to achieve drying of the volatile oil on the heat exchanger fins.
[0061] In some embodiments of the present application, the drying device further comprises:
[0062] The conveying line body 600 is used to convey the objects to be dried, and includes: a first end 610;
[0063] A second end 620 disposed opposite to the first end 610;
[0064] The first end 610 corresponds to the front end of the conveying line body 600 , and the second end 620 corresponds to the rear end of the conveying line body 600 .
[0065] In some embodiments, the drying device includes a complete machine frame, and the conveyor line body 600 is assembled on the complete machine frame. The conveyor line can be an existing belt conveyor line or a roller conveyor line, and the items to be dried arranged above it are conveyed along the direction from the first end 610 to the second end 620.
[0066] In some embodiments, the condenser module is assembled on the whole machine frame and arranged above the conveying line body 600 .
[0067] There are two heating air ducts 400 , which are respectively connected to two sides of the housing 100 .
[0068] When two heating ducts 400 are arranged, one heating duct 400 extends along the length direction of the conveyor line 600 to a position close to the first end 610; the other heating duct 400 extends along the length direction of the conveyor line 600 to a position close to the second end 620.
[0069] The heating air duct 400 is arranged into two and extends along the first end 610 and the second end 620 on both sides of the shell 100 in the length direction of the conveying line body 600, so that the airflow after heat exchange through the condenser module 200 can be transported to the two end positions of the conveying line body 600, namely the first end 610 and the second end 620, respectively, thereby ensuring that the fins on the conveying line body 600 are dried by airflow at both ends, ensuring that the volatile oil on the fins is dried more fully, ensuring the drying effect.
[0070] In some embodiments of the present application, the air outlet portion includes: a first air outlet portion 121, which is arranged on one side of the shell 100 near the first end 610, and a first internal flow channel 130 is formed between the return air portion 110 and the first air outlet portion 121, which allows the air flow to flow through the condenser module 200 or not flow through the condenser module 200, and the first internal flow channel 130 is connected to the heating air duct 400 near the first end 610.
[0071] In some embodiments, the return air portion 110 is disposed at the bottom of the housing 100 to absorb the airflow after heat exchange with the fins at the conveyor line body 600 .
[0072] The first air outlet portion 121 is disposed on a side wall of the housing 100 and connected to the heating air duct 400 near the first end 610 .
[0073] The airflow sucked from the return air portion 110 by the main air supply device 500 enters the interior of the housing 100 and passes through the condenser module 200. After passing through the condenser module 200, the airflow is heat-exchanged and enters the first air outlet 121 and the heating air duct 400 connected to the first air outlet 121 to dry the heat exchanger fins at the first end 610 of the conveying line body 600.
[0074] Alternatively, the airflow from the return air portion 110 to the housing 100 does not flow through the condenser module 200 but flows through the housing 100 and then enters the heating air duct 400 to dry the heat exchanger fins through the heating air duct 400 .
[0075] Since the condenser module 200 exchanges heat with the air inside the shell 100 , the outflow airflow can be guaranteed to be a heated airflow even if the air does not flow through the condenser module 200 , and the fin heat exchanger can also be dried.
[0076] The second air outlet portion 122 is arranged on the other side of the shell 100 near the second end 620, and a second internal flow channel 140 is formed between the return air portion 110 and the second air outlet portion 122, which allows the air flow to flow through the condenser module 200 or not. The second internal flow channel 140 is connected to the heating air duct 400 near the second end 620.
[0077] The second air outlet portion 122 is a second air outlet formed on the other side of the housing 100 .
[0078] Part of the air flow flowing in from the return air section 110 enters the first internal flow channel 130, and part enters the second internal flow channel 140 and then enters the heating air duct 400 near the second end 620, and is dried by the heat exchanger fins at the second end 620 of the conveying line body 600.
[0079] In some embodiments, the condenser module 200 is arranged on the airflow path of the second internal flow channel 140, so that the airflow passes through the condenser module 200, and the airflow is heated and the heating effect is good.
[0080] In some embodiments, the condenser module 200 is not on the air flow path of the second internal flow channel 140. Due to the heat exchange between the condenser module 200 and the internal space of the shell 100, it can also be ensured that the air flow flowing out of the second internal flow channel 140 is a heated air flow, thereby ensuring the drying effect of the heat exchanger fins.
[0081] In some embodiments of the present application, the condenser module 200 includes: a first condenser 210;
[0082] and a second condenser 220 arranged side by side with the first condenser 210;
[0083] The air outlet portion includes: a first air outlet portion 121, which is arranged on one side of the first condenser 210 and is close to the first condenser 210, and a first internal flow channel 130 is formed between the return air portion 110 and the first air outlet portion 121 to allow air flow to flow through the first condenser 210;
[0084] The second air outlet portion 122 is arranged at one side of the second condenser 220 and is disposed close to the second condenser 220 . A second internal flow channel 140 is formed between the return air portion 110 and the second air outlet portion 122 , allowing air to flow through the second condenser 220 .
[0085] By setting up two condensers and arranging the two condensers on the flow path of the first internal flow channel 130 and the flow path of the second internal flow channel 140 respectively, the airflow sucked in from the return air portion 110 can be diverted to the first internal flow channel and the second internal flow channel to exchange heat with the two condensers respectively, with good heat exchange effect, ensuring the rapidity and uniformity of the temperature rise of the airflow delivered to the two heating air ducts 400.
[0086] In some embodiments of the present application, the condenser module 200 includes: a condensing component;
[0087] The air outlet portion includes: a first air outlet portion 121, which is arranged at one side of the housing 100, and a first internal flow channel 130 is formed between the return air portion 110 and the first air outlet portion 121, which allows the airflow to flow through the condensation component or not flow through the condensation component;
[0088] The second air outlet 122 is arranged at the other side of the housing 100 , and a second internal flow channel 140 is formed between the return air portion 110 and the second air outlet 122 , which allows the airflow to flow through the condensation component or not.
[0089] In some embodiments, the condensation component is arranged at the middle position of the shell 100. The airflow flowing into the return air portion 110 flows into the interior of the shell 100 and then flows through the condensation component for heat exchange. The airflow that has exchanged heat with the condensation component is split into the first air outlet 121 and the second air outlet 122 for delivery.
[0090] In some embodiments, the condensation component is arranged at any position of the shell 100. After the refrigerant flows through the condensation component, it exchanges heat with the air in the shell 100 to heat the air inside the shell 100. The airflow entering from the return air part 110 does not flow through the condensation component, but it takes away the heated airflow inside the shell 100 to achieve the drying effect of the heat exchanger fins.
[0091] In some embodiments of the present application, the heating duct 400 includes:
[0092] The fan duct 420 is provided with the main air supply device 500;
[0093] A first connecting air duct 430 connected between the fan air duct 420 and the air outlet of the housing 100;
[0094] The lower air duct 440 is connected to the fan air duct 420 and extends downward and bends to the bottom position of the conveyor line body 600. The air duct outlet portion 410 is formed on the lower air duct 440.
[0095] The heating air duct 400 is formed by sequentially connecting the first connecting air duct 430 , the fan air duct 420 and the lower air duct 440 .
[0096] The airflow flowing out from the air outlet of the housing 100 enters the first connecting air duct 430 and the fan air duct 420 and then reaches the lower air duct 440 , and is blown toward the conveying line body 600 through the air duct outlet 410 on the lower air duct 440 .
[0097] In some embodiments, the air duct outlet portion 410 is an air duct outlet, which faces the bottom surface of the conveyor line body 600 to blow air flow from the bottom to the heat exchanger fins on the conveyor line body 600, so that the air flow can flow from the bottom to the top through the heat exchanger fins, thereby ensuring the drying effect of the heat exchanger fins.
[0098] In some embodiments of the present application, the heating duct 400 further includes:
[0099] The upper suction duct 450 is connected to the fan duct 420 and extends downward to the top surface of the conveyor line body 600. An auxiliary suction portion is formed above it for sucking the airflow into the fan duct 420 through the auxiliary suction portion when the main air supply device 500 is running.
[0100] The air flow rate sucked in by the single main air supply device 500 through the suction part is limited. In order to ensure the drying effect on the heat exchanger fins, the upper suction duct 450 is connected to the fan duct 420, which faces the top surface of the conveyor line body 600 and can be used to suck the airflow in the top area of the heat exchanger fins after heat exchange into the fan duct 420, and then enter the lower duct 440 for drying, thereby increasing the airflow suction amount and improving the drying effect.
[0101] Through the cooperation of the return air section 110 and the auxiliary adsorption section, the air flow entering the heating air duct 400 is composed of two paths. The air flow after heat exchange with the heat exchanger fins can be sucked into the hot air duct through the return air section 110 and the auxiliary adsorption section. The temperature of the heat-absorbing air flow is about 90~100℃. After being heated by the condenser module 200, the temperature of the air becomes 110~120℃, and then output through the downwind duct 440 into the heat exchanger fins on the conveying line body 600.
[0102] In some embodiments of the present application, an auxiliary heating module 700 is included, which is connected to the heating air duct 400. When the condenser module 200 cannot heat the airflow to the drying temperature or fails, the auxiliary heating module 700 can be turned on to perform auxiliary heating.
[0103] The auxiliary heating module 700 is on the heating air duct 400, so that it can be turned on or off according to actual usage requirements.
[0104] When turned on, the heat generated can be directly transported to the heating duct 400 for auxiliary heating.
[0105] In some embodiments, the auxiliary heating module 700 includes:
[0106] The auxiliary heating shell constitutes the outer shell of the entire auxiliary heating module 700 , and the auxiliary heating shell is connected to the heating air duct 400 .
[0107] In some embodiments, the auxiliary heating shell is connected to the first connecting duct 430 , to the lower duct 440 , to the upper suction duct 450 , between the first connecting duct 430 and the fan duct 420 , between the upper duct and the fan duct 420 , or between the fan duct 420 and the lower duct 440 .
[0108] The auxiliary heating element is assembled in the auxiliary heating shell, and the auxiliary heating element is located on the flow path of the air flow of the heating air duct 400 .
[0109] The auxiliary heating element generates heat by being powered on. When the airflow cannot be heated to the required drying temperature by heat exchange through the condenser module 200, the auxiliary heating element is turned on to generate heat and cooperate with the condenser module 200 to increase the temperature of the airflow.
[0110] In some embodiments, the auxiliary heating element is an auxiliary heating plate that generates heat when powered on.
[0111] In some embodiments of the present application, the side air supply module 800 can be used to dry the heat exchanger fins on the conveyor line body 600.
[0112] The side air supply module 800 includes: a side air supply duct connected to the housing 100;
