Description

Technical Field

[0001] The present invention relates to the technical field of energy-saving drying ovens, and in particular to an energy-saving odor-removing drying oven for processing automotive interior fabrics. Background Art

[0002] A drying oven (also known as a drying chamber or drying room) is a device used in industrial production to heat, dry, or cure products. It is widely used in many fields such as food processing, chemical industry, pharmaceuticals, textiles, and automotive manufacturing. The drying oven controls parameters such as temperature, humidity, and ventilation to ensure that the product achieves an ideal drying effect during processing while maintaining a high-quality appearance and performance.

[0003] Its main working principle is as follows.

[0004] Heating: Generate high temperature through methods such as electric heating, gas heating, steam heating, or heat pump heating to evaporate moisture or other volatile substances on the surface of the product.

[0005] Ventilation: Use a forced ventilation system to ensure air circulation in the drying oven, remove volatile organic compounds (such as VOCs) and moisture, and keep the air fresh.

[0006] In the drying ovens of the prior art, the main way to save energy is to improve the heat exchange efficiency of heat exchange or utilize waste heat to achieve the purpose of energy conservation. The prior art mainly consumes fuel, and a large amount of heat is generated by fuel combustion to heat and dry the product or material; this method consumes a large amount of fuel and is not energy-saving and environmentally friendly enough. To further achieve energy conservation, the prior art uses the form of a heat pump to achieve the effect of energy conservation. However, in the solution where the product needs to remove odor, using water to remove odor will increase the humidity of the product or material, increase the energy consumption of drying, and instead increase the demand for energy consumption. Therefore, the drying ovens of the prior art have the problem of insufficient energy conservation. Summary of the Invention

[0059] The odor removal and drying oven for automotive interior parts is a facility designed specifically for removing the odor of automotive interior parts. An advanced ventilation system and heating technology are adopted inside the oven, which can effectively remove harmful gases and odors in the interior parts. At the same time, the temperature and humidity inside the oven can be regulated to ensure that the interior parts will not be damaged while removing the odor. In addition, the oven is reasonably designed and easy to operate, greatly improving the production efficiency. The odor removal and drying oven for automotive interior parts has high working efficiency. The air inlet and exhaust devices can adjust the air change rate of the working chamber.

An imported high-precision intelligent program temperature control instrument can be selected for temperature control, with self-adjustment of PID parameters and power regulation by solid state relays. Multiple-section program temperature control curves can be preset. The intelligent temperature control instrument for temperature control is sensitive and reliable in control.

[0060] The wind power system meets the standards of relevant specifications.

[0061] 1). The hot air circulation system adopts the European concept of air outlet on both sides and air return in the middle, and a large-capacity fan is used for forced air movement.

[0062] 2). The wind power is divided into an exhaust system and a circulation system; the two systems work independently.

[0063] 3). The exhaust system is to discharge the excess heat in the room to the outside when the indoor temperature exceeds the required temperature of the product.

[0064] 4). The exhaust system adopts the design concept of combining air ducts and fans. The circulation fan continuously makes the air in the room do convective circulation movement; ensuring the uniformity of the indoor temperature.

[0065] 5). The heater is installed on the top of the aging room and adopts PID control.

[0067] Please refer to Figures 1 - 11 As shown, an energy-saving odor-removing drying room for processing automotive interior fabrics according to an exemplary embodiment of the present invention includes a drying room body 10, an odor-removing system, and a heat supply circulation system; the odor-removing system and the heat supply circulation system are respectively connected to the drying room body 10;

[0068] The heat supply circulation system includes a circulation pipeline 20, a compressor 35, a heating coil A0, a throttle valve 32, an evaporator 33, a buffer tank 34, and a fan 31; the compressor 35, the throttle valve 32, the evaporator 33, and the buffer tank 34 are sequentially installed on the circulation pipeline 20;

[0069] A section of the circulation pipeline 20 located inside the drying room body 10 is coiled and forms a heating coil A0, and the heating coil A0 is located between the compressor 35 and the throttle valve 32;

[0070] The heating coil A0 and the fan 31 are installed inside the drying room body 10;

[0071] The fan 31 is installed on one side of the heating coil A0, and the air direction of the fan 31 faces the heating coil A0 to spread the heat generated by the heating coil A0 into the drying room body 10;

[0072] The odor-removing system includes a water supply pipe 40, a sleeve 36, a spray head 61, an air extraction head 71, and an air extraction pipe 73;

[0073] The sleeve 36 is used to conduct the heat of the circulation pipeline 20 into the water supply pipe 40;

[0074] The sleeve 36 is sleeved on the circulation pipeline 20 between the heating coil A0 and the throttle valve 32; the water supply pipe 40 is communicated with the sleeve 36, and a spray head 61 is installed at one end of the water supply pipe 40;

[0075] The air extraction head 71 is installed on the same side as the spray head 61, and the air extraction head 71 is connected to the air extraction pipe 73.

[0076] In the present invention, the medium in the circulation pipeline 20 can be water or other refrigerants, such as freon, alkane, ammonia, carbon dioxide, brine, etc.

[0077] Refer toFigure 2 As shown, in the circulating pipeline 20, the medium is compressed in the compressor 35 to form a high-pressure state and the temperature rises. Then, at the condenser (i.e., the heating coil A0 in the present invention), the high-temperature and high-pressure medium takes away heat and is cooled, and at this time, a low-temperature and high-pressure medium is obtained. Then, it throttles and expands at the throttle valve 32 and the pressure decreases, accompanied by a further decrease in temperature. The low-temperature medium takes away the cooling capacity at the evaporator 33, and this cooling capacity can be used for refrigeration in the air-conditioning system. The temperature of the medium rises and becomes a normal-temperature and low-pressure state, and then enters the compressor 35 again. This is the main process of the whole cycle. In this process, there are also multi-stage heat dissipation of the heating coil A0, further heat is taken away in the sleeve 36, and the liquid phase in the buffer tank 34 is temporarily stored and other processes.

[0078] In some preferred embodiments, a plurality of heat dissipation columns 51 are formed on the outer surface of the heating coil A0, and the plurality of heat dissipation columns 51 are arranged in parallel;

[0079] Heat dissipation fins 52 are installed on the heat dissipation columns 51, and the plurality of heat dissipation fins 52 are evenly distributed outside the heating coil A0; the heat dissipation fins 52 are used to accelerate the heat diffusion of the heating coil A0;

[0080] A wind shield 53 is further formed outside the heating coil A0, and the wind shield 53 is installed on one side of the outside of the heating coil A0 facing the fan 31 for blocking the wind of the fan 31;

[0081] A gap is formed between the wind shield 53 and the outer wall of the heating coil A0.

[0082] The heat dissipation columns 51 and the heat dissipation fins 52 are provided to accelerate the heat diffusion of the heating coil A0 and accelerate the temperature reduction of the medium in the heating coil A0.

[0083] In some preferred embodiments, the fan 31 is installed on the top of the drying chamber body 10, and the air outlet of the fan 31 faces downward;

[0084] The heating coil A0 and the heat dissipation fins 52 are located below the air outlet of the fan 31;

[0085] Intervals are respectively formed between the plurality of heat dissipation fins 52 for ventilation; the heat dissipation fins 52 take away the heat of the heating coil A0, and through the wind force provided by the fan 31, the heat on the heat dissipation fins 52 is taken away, thereby generating a hot air circulation in the drying chamber body 10.

[0086] The fan 31 blowing air downward is beneficial to improving the thermal efficiency of the entire drying chamber body 10, and avoids the problems of drying dead angles and poor flow, and improves the drying efficiency.

[0087] In some preferred embodiments, the heat dissipation fins 52 are obliquely installed on the heat dissipation columns 51;

[0088] The heat dissipation fins 52 include a straight plate portion 531 and a serrated portion 532; the straight plate portion 531 is installed on the upper surface of the heat dissipation column 51, and the serrated portion 532 is installed on the lower surface of the heat dissipation column 51;

[0089] The straight plate portion 531 is used to guide the wind direction, and the serrated portion 532 is used to increase the heat dissipation area and accelerate the heat dissipation of the heating coil A0.

[0090] The upper half of the heat dissipation fin 52 is the straight plate portion 531, and the lower half is the serrated portion 532. The structural shapes of the two parts are different, and the functions they perform are also different. Such a structure of the heat dissipation fin 52 of the present invention can improve the heat dissipation efficiency compared with the prior art.

[0091] In some preferred embodiments, the spray head 61 is in a long strip shape and is horizontally placed obliquely above the conveying roller 82 in the drying chamber body 10;

[0092] A plurality of atomizing spray holes 62 are formed on the bottom surface of the spray head 61;

[0093] The air extraction head 71 is in a long strip shape and is horizontally placed above another conveying roller 82 in the drying chamber body 10;

[0094] The spray head 61 and the air extraction head 71 are respectively disposed at two adjacent conveying rollers 82.

[0095] In some preferred embodiments, a cover body is formed on the air extraction head 71, and an air extraction port 74 facing downward is formed on the bottom surface of the cover body;

[0096] The air extraction port 74 is disposed above the material;

[0097] On the outer wall of the circulation pipeline 20 in the sleeve 36, a plurality of heat conducting fins 362 are formed, and the plurality of heat conducting fins 362 are radially distributed on the outer wall of the circulation pipeline 20;

[0098] End caps 361 are respectively formed at both ends of the sleeve 36, and the water supply pipe 40 is disconnected between the two end caps 361 and communicates with the inner cavity of the sleeve 36.

[0099] The water supply pipe 40 is formed in two sections. One end of one section is connected to one end cap 361 of the sleeve, one end of the other section is connected to the other end cap 361, and the other end of the other section is connected to the spray head 61. Therefore, the water in the water supply pipe 40 enters the sleeve 36 and directly exchanges heat with the outer wall of the circulation pipeline 20, and the heated water enters the spray head 61, with high thermal efficiency.

[0100] Both ends of the nozzle 61 are installed on the winding rack 12 of the drying chamber body 10 through the mounting base 63. Both ends of the air extraction head 71 are installed on the winding rack 12 of the drying chamber body 10 through the connecting seat 72. A plurality of conveying rollers 82 are installed on the winding rack. The conveying rollers 82 are used for conveying the fabric.

[0101] As Figure 8 demonstrates the surrounding relationship between the conveying roller 82 and the fabric 81, and also shows the distribution relationship between the nozzle 61 and the air extraction head 71, as well as the positional relationship between the nozzle 61 and the air extraction head 71 and the fabric 81.

[0102] In the present invention, the water entering the nozzle 61 has been heated, even reaching the temperature inside the drying chamber body 10, consuming less heat in the drying chamber, thus saving energy.

[0103] In some preferred embodiments, the throttle valve 32 is an electric valve, and the electric valve is electrically connected to the controller;

[0104] The opening amount of the electric valve is controlled by the controller, thereby adjusting the effect of throttling expansion;

[0105] The heating coil A0 is a multi-layer tube structure;

[0106] The structure of the multi-layer tube is stacked layer by layer, with the head end of each layer connected to the tail end of another layer and placed spirally.

[0107] A cold air circulation system is provided at the evaporator 33. The cold air circulation system absorbs the cold generated by the evaporator 33 and raises the temperature of the circulating liquid in the evaporator 33;

[0108] The cold taken away from the evaporator 33 can be used for room cooling.

[0109] In some preferred embodiments, the buffer tank 34 is provided with a liquid replenishment channel, and the liquid replenishment channel communicates with the bottom inside the buffer tank 34 for discharging the liquid inside the buffer tank 34 or for replenishing the liquid into the buffer tank 34.

[0110] In some preferred embodiments, a circulation pump (not shown in the figure) is further provided, and the circulation pump is installed on the circulation pipeline 20;

[0111] The circulation pump is a power source for circulating the liquid on the circulation pipeline 20, promoting the flow of the liquid in the circulation pipeline 20.

[0112] In the present invention, the fan 31 ventilates downward, realizing the vertical air flow inside the drying chamber body 10, and thus can improve the heat transfer efficiency inside the drying chamber body 10 and accelerate drying.

[0113] The water in the water supply pipe 40 exchanges heat with the liquid in the circulation pipeline 20 at the sleeve 36, thereby heating the water in the water supply pipe 40 and making more use of the heat in the circulation pipeline 20. After the water in the water supply pipe 40 is heated, it is sprayed onto the material on the conveying roller 82 through the nozzle 61, increasing the water content of the material, thereby absorbing the odor in the material and achieving the effect of odor removal.

[0114] Then, this part of the water is negatively adsorbed at the air extraction head 71 and discharged, thereby reducing the water content of the material. The material being air extracted continues to be conveyed on the conveying rack and dried in the drying chamber body 10 to reach the expected moisture content.

[0115] The air extraction head 71 is strip-shaped, and the air extraction port 74 is strip-shaped.

[0116] The position of the nozzle 61 and the position of the air extraction head 71 are preferably separated by one layer of the conveying roller 82; that is, the nozzle 61 is arranged at the conveying roller 82 at the end of one layer, and the air extraction head 71 is arranged at the conveying roller 82 of the adjacent layer. This not only plays the role of odor removal but also reduces the heat used for drying the material in the drying chamber body 10.

[0117] Compared with the prior art, the heat in the present invention is fully utilized, and the cold quantity can also be utilized, achieving a full energy-saving effect; and the heat conduction efficiency is high, and the heat is fully utilized; in the drying chamber, the hot air blows vertically, and the heat efficiency reaches the maximum; finally, while removing the odor, there is no need to provide additional heat to heat the water for odor removal, reducing the heat usage. In summary, the present invention has high heat efficiency, achieving both odor removal and energy conservation.

[0118] The above-described embodiments merely represent several implementation manners of the present invention. Their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention.
