It is widely used in food processing, chemical industry, metallurgy, building materials, electronics, medicine and other industries. It is efficient and environmentally friendly. When the tunnel furnace is working, the heat generated by the heating elements is transferred to the materials or products through heat conduction, convection, and radiation. Driven by the conveying system, the materials enter the tunnel furnace from the entrance, pass through different temperature zones such as the preheating zone, heating zone, and insulation zone, complete the baking, drying, and curing processes, and are finally sent out from the exit.

[0003] Existing tunnel ovens generally heat products through built-in heating tubes, which have the following defects: existing technical equipment can only provide heating and baking effects but cannot provide sterilization effects, and some products have high requirements for sterilization functions, and the built-in heating tubes need to be replaced frequently.

[0009] Furthermore, a plurality of evenly distributed rubber sleeves are fixedly installed on the conveyor belt, and a plurality of socket holes adapted to the rubber sleeves are opened on both sides of the transparent conveyor belt. The plurality of rubber sleeves located on the same side are respectively inserted into the interior of the plurality of socket holes, and transparent tape is glued at the seams at both ends of the transparent conveyor belt.

[0010] Furthermore, the transparent conveyor belt is provided with a plurality of evenly distributed air holes, a suction fan is fixedly installed on the top of the tunnel shell, the air inlet of the suction fan is connected to the interior of the tunnel shell, and an air duct is fixedly installed on the air outlet of the suction fan.

[0011] Furthermore, a plurality of evenly distributed drainage holes are provided on the bottom inner wall of the lamp tray, and the bottom inner wall of the lamp tray is a slope structure inclined toward the drainage holes. The interior of the drawer racks is fixedly installed with horizontally arranged open water troughs, and the open water troughs located on the same side are located at the bottom of the plurality of drainage holes. Two drainage pipes are fixedly installed on one side of the tunnel furnace base, and one end of the two drainage pipes respectively extends to the interior of the two drawer racks and is respectively connected to the interior of the two open water troughs.

[0013] Furthermore, an activated carbon air filter box is provided on one side of the tunnel furnace base, one end of the air supply pipe is connected to the interior of the activated carbon air filter box, and an exhaust pipe is fixedly installed on one side of the activated carbon air filter box.

[0014] Furthermore, longitudinal linear guide rails are installed on both side walls of the tunnel shell, a connecting frame is fixedly connected to the transmission component of the longitudinal linear guide rail, a transverse linear guide rail is installed at the bottom of the connecting frame, and a top lamp tray is installed on the transmission component of the transverse linear guide rail. The top lamp tray has the same structural features as the lamp tray, and is also equipped with a lamp socket, power plug and ultraviolet sterilization lamp, and the irradiation surface of the top lamp tray is downward.

[0015] The beneficial effects of the present invention are as follows:

[0016] 1. When the present invention is in use, a lamp tray loaded with ultraviolet germicidal lamps is placed inside the tunnel furnace. The built-in heating tubes of the tunnel furnace itself can heat and dry the products conveyed on the tunnel furnace, while the ultraviolet germicidal lamps inside the lamp tray can sterilize and disinfect the products being dried, so that the products are subjected to a dual treatment of heating and sterilization. At the same time, the ultraviolet germicidal lamps are integrated into the lamp tray by a fixed plug-in method. The integrated structure of the drawer-type sliding tray makes it easy to remove the lamp tray from the tunnel furnace for maintenance.

[0017] 2. During maintenance, the present invention allows the two lamp trays to be quickly pulled out of the drawer frame, facilitating the maintenance of the ultraviolet germicidal lamps and the cleaning of the lamp trays themselves. When maintenance is completed, the lamp trays can be reinserted into the drawer frame. The power plug on one side of the lamp tray will automatically connect to the power socket as the lamp tray slides in the drawer frame, allowing the ultraviolet germicidal lamps to be reconnected to the control circuit inside the tunnel furnace base. Finally, the drawer side cover is closed to complete the installation. The operation is simple and quick, which improves the installation method of the lamps and heating elements, greatly improves the efficiency of subsequent maintenance, and saves maintenance costs.

[0018] 3. The present invention provides a transparent conveyor belt, so that the conveyor motor on one side of the tunnel furnace base will synchronously drive the two conveyor rollers to rotate in the same direction, thereby driving the conveyor belts on both sides to operate, and then the products placed on the transparent conveyor belt are driven to move through the transparent conveyor belt in the middle. The transparent material of the transparent conveyor belt will not cause excessive obstruction and reflection of the ultraviolet light emitted by the ultraviolet germicidal lamp below, so that the sterilization and disinfection function of the ultraviolet germicidal lamp can take effect normally;

[0019] 4. The present invention provides a rubber sleeve rod, so that when the transparent conveyor belt ages, cracks, or deforms after long-term high-temperature baking, the transparent tape at the seam of the transparent conveyor belt can be torn to separate the two ends of the transparent conveyor belt. Then, one end of the transparent conveyor belt can be lifted. As the conveyor belt runs, the sleeve holes and the rubber sleeve rod are separated in sequence until the transparent conveyor belt is completely removed. Then, the operation is reversed and a new transparent conveyor belt is installed between the two conveyor belts, thereby realizing rapid replacement of the transparent conveyor belt.

[0020] 5. The present invention provides an exhaust fan so that when baking and sterilizing the product, the exhaust fan will blow air regularly to extract gas from the interior of the tunnel shell, so that the moisture and exhaust gas generated by baking are extracted, keeping the interior of the tunnel shell dry and clean. At the same time, air flow is formed inside the tunnel furnace base and passes through the sides of the product through the air holes on the transparent conveyor belt. The high-temperature air flow is used to air-dry the product, thereby accelerating the drying speed of the product.

[0021] 6. The present invention provides drainage holes so that when a lamp tray loaded with ultraviolet germicidal lamps is used to sterilize products, the moisture generated by the product evaporation during baking condenses into dew drops that fall inside the lamp tray and flow along the slope into the drainage holes. The dew is then transported to the water storage tank through the open water receiving trough and the drainage pipe, thereby ensuring the cleanliness of the lamp tray and the interior of the tunnel furnace base.

[0022] 7. The present invention provides a reinforcing ring and a reinforcing net so that when the conveyor mat and the transparent conveyor belt are conveyed, the reinforcing ring in the socket hole contacts the rubber sleeve rod, effectively preventing the socket hole from being torn or deformed due to stress caused by the conveyor mat pulling the transparent conveyor belt. At the same time, the reinforcing net connected to the reinforcing ring is located inside the transparent conveyor belt, which can improve the structural strength of the transparent conveyor belt, make the force on the transparent conveyor belt more uniform, and prevent the transparent conveyor belt from deforming during the conveying process.

[0023] 8. The present invention sets an activated carbon air filter box so that the mixed gas of moisture and exhaust gas extracted from the tunnel shell by the exhaust fan will be transported to the activated carbon air filter box through the air duct. The mixed gas will be adsorbed by impurities and moisture by the activated carbon particles inside the activated carbon air filter box, and the temperature of the mixed gas will be reduced at the same time, so that the purified, dried and cooled gas will eventually be discharged through the exhaust pipe, ensuring the cleanliness of the environment around the tunnel furnace.

[0039] like Figures 1 to 10 As shown, a tunnel furnace using an ultraviolet germicidal lamp includes a lamp tray 6, such as Figure 5 、 Figure 6 As shown, a guide frame 7 is fixedly installed on the top of the lamp tray 6, and a lamp socket 8 is fixedly installed inside the lamp tray 6. A plurality of evenly distributed ultraviolet sterilization lamps 10 are fixedly plugged on the top of the lamp socket 8. The lamp tray 6 is used to load the ultraviolet sterilization lamps 10 and is placed in the tunnel furnace to provide drying and sterilization functions for the conveyed products. A power plug 9 is fixedly installed on one side of the lamp tray 6, and the power plug 9 is electrically connected to the lamp socket 8; specifically, when the ultraviolet sterilization lamp is in use, the lamp tray 6 loaded with the ultraviolet sterilization lamps 10 can be placed inside the tunnel furnace. The built-in heating tube of the tunnel furnace itself can heat and dry the products conveyed on the tunnel furnace, and the ultraviolet sterilization lamps 10 inside the lamp tray 6 can sterilize and disinfect the products being dried, so that the products are subjected to dual treatment of heating and sterilization. At the same time, the ultraviolet sterilization lamps 10 are integrated in the lamp tray 6 by fixed plugging. The integrated structure of the drawer-type sliding tray makes it convenient to take the lamp tray 6 out of the tunnel furnace for maintenance.

[0040] A tunnel furnace using an ultraviolet germicidal lamp includes a tunnel furnace base 1. In this embodiment, the interior of the tunnel furnace base 1 is provided with a common electric heating tube on the market, such as Figure 1 As shown, the inner drive of the tunnel furnace base 1 is equipped with a conveyor belt assembly 2, and the top of the tunnel furnace base 1 is fixedly equipped with a tunnel shell 3, as shown in FIG. Figure 4 As shown, two drawer racks 4 are fixedly installed inside the tunnel furnace base 1. Figure 3 As shown, one side of the tunnel furnace base 1 is provided with two drawer holes, the positions of the two drawer holes respectively correspond to the positions of the two drawer frames 4, and the drawer side flaps 5 are rotatably installed inside the drawer holes. Figure 4 As shown, the two lamp trays 6 are respectively placed inside the two drawer racks 4, and the two guide racks 7 are respectively slidably installed inside the two drawer racks 4. The two drawer racks 4 are both located at the bottom of the tunnel shell 3, and the drawer racks 4 are fixedly installed with power sockets compatible with the power plugs 9. Specifically, when the tunnel furnace is in use, the product is placed on the conveyor belt assembly 2 for transportation, so that the product is sent into the tunnel shell 3 to stay, or the transportation speed is reduced to make the product move slowly, so that the electric heating tube inside the tunnel furnace base 1 and the ultraviolet sterilization lamp 10 on the lamp tray 6 are used to heat, dry and sterilize the product, which plays a dual role of sterilization and heating and baking. At the same time, the ultraviolet sterilization lamp 10 is integrated in the lamp tray 6. When the ultraviolet sterilization lamp 10 needs to be turned on When performing maintenance and replacement, the drawer side flap 5 can be opened and the two lamp trays 6 can be quickly pulled out from the drawer rack 4, which facilitates the maintenance of the ultraviolet germicidal lamps 10 and the cleaning of the lamp trays 6 themselves. Afterwards, the ultraviolet germicidal lamps 10 on the lamp sockets 8 can be checked or replaced one by one. When the maintenance is completed, the lamp tray 6 can be reinserted into the drawer rack 4. The power plug 9 on one side of the lamp tray 6 will automatically connect with the power socket as the lamp tray 6 slides in the drawer rack 4, so that the ultraviolet germicidal lamps 10 are reconnected to the control circuit inside the tunnel furnace base 1. Finally, the drawer side flap 5 can be closed to complete the installation. The operation is simple and quick, which improves the installation method of the lamps and heating elements, greatly improves the efficiency of later maintenance, and saves maintenance costs.

[0041] like Figure 7 As shown, the conveyor belt assembly 2 includes two conveyor rollers 201 driven and installed inside the tunnel furnace base 1. The conveyor rollers 201 are horizontally arranged and parallel to each other. Conveyor pads 202 are tensioned at both ends of the two conveyor rollers 201. In this embodiment, the two conveyor rollers 201 are tensioned at one end on the same side with the same conveyor pad 202, and the other ends of the two conveyor rollers 201 are tensioned with a second conveyor pad 202. The same transparent conveyor belt 203 is arranged between the two conveyor pads 202, and the two lamp trays 6 are both located inside the transparent conveyor belt 203. Figure 2As shown, two conveying motors 12 are fixedly installed on one side of the tunnel furnace base 1, and the output shafts of the two conveying motors 12 are respectively connected to the two conveying rollers 201; specifically, by setting a transparent conveyor belt 203, the conveying motor 12 on one side of the tunnel furnace base 1 will synchronously drive the two conveying rollers 201 to rotate in the same direction, thereby driving the conveying pads 202 on both sides to operate, and then driving the products placed above the transparent conveyor belt 203 to move through the transparent conveyor belt 203 in the middle. The transparent conveyor belt 203 made of transparent material will not cause excessive obstruction and reflection of the ultraviolet rays emitted by the ultraviolet germicidal lamp 10 below, so that the sterilization and disinfection function of the ultraviolet germicidal lamp 10 can take effect normally.

[0042] like Figure 8 As shown, a plurality of evenly distributed rubber sleeve rods 204 are fixedly installed on the conveyor belt 202, and a plurality of socket holes adapted to the rubber sleeve rods 204 are opened on both sides of the transparent conveyor belt 203. The plurality of rubber sleeve rods 204 located on the same side are respectively inserted into the interior of the plurality of socket holes, and transparent adhesive tape 205 is glued to the seams at both ends of the transparent conveyor belt 203. Specifically, by arranging the rubber sleeve rods 204, the rubber sleeve rods 204 are matched with the socket holes on both sides of the transparent conveyor belt 203, so that the transparent conveyor belt 203 and the conveyor belts 202 on both sides can be mutually connected. Separation: When the transparent conveyor belt 203 shows problems of aging, cracking, and deformation under long-term high-temperature baking, the transparent tape 205 at the seam of the transparent conveyor belt 203 can be torn off to separate the two ends of the transparent conveyor belt 203, and then one end of the transparent conveyor belt 203 can be lifted. As the conveyor pad belt 202 runs, the various socket holes and rubber sleeve rods 204 are disengaged in turn until the transparent conveyor belt 203 is completely removed, and then the operation is reversed to install a new transparent conveyor belt 203 between the two conveyor pad belts 202 to achieve rapid replacement of the transparent conveyor belt 203.

[0043] like Figure 8 As shown, the transparent conveyor belt 203 is provided with a plurality of evenly distributed ventilation holes 208. Figure 1 As shown, an exhaust fan 13 is fixedly installed on the top of the tunnel shell 3, the air inlet of the exhaust fan 13 is connected to the interior of the tunnel shell 3, and the air outlet of the exhaust fan 13 is fixedly installed with an air duct 14; specifically, by arranging the exhaust fan 13, when the product is baked and sterilized, the exhaust fan 13 will blow air regularly to extract gas from the interior of the tunnel shell 3, so that the moisture and exhaust gas generated by baking are extracted, and the interior of the tunnel shell 3 is kept dry and clean. At the same time, airflow is formed inside the tunnel furnace base 1, and passes through the surrounding side of the product through the air vents 208 on the transparent conveyor belt 203, and the product is air-dried by using the high-temperature airflow, thereby accelerating the drying speed of the product.

[0044] like Figure 5 、 Figure 6 As shown, a plurality of evenly distributed drainage holes 11 are provided on the bottom inner wall of the lamp tray 6, and the bottom inner wall of the lamp tray 6 is a slope structure inclined toward the drainage holes 11, as shown in FIG. Figure 4 As shown, the drawer frame 4 is fixed with a horizontally arranged open water tank, and the open water tank on the same side is located at the bottom of the plurality of drainage holes 11, as shown in FIG.

A water storage tank 18 is fixedly installed on one side of the bottom of the tunnel furnace base 1, and the water storage tank 18 is located below the bottom ends of the two drainage pipes 17; specifically, by providing drainage holes 11, when the lamp tray 6 loaded with ultraviolet sterilization lamps 10 is used to sterilize the product, the moisture generated by baking and evaporation of the product condenses into dew drops and falls on the inside of the lamp tray 6 and flows into each drainage hole 11 along the slope, and is finally transported to the water storage tank 18 through the open water receiving tanks and the drainage pipes 17, thereby ensuring the cleanliness of the lamp tray 6 and the inside of the tunnel furnace base 1.

[0045] like Figure 8 As shown, the interior of the sleeve holes are fixedly installed with reinforcement rings 206, and the multiple rubber sleeve rods 204 located on the same side are respectively inserted into the interiors of the multiple reinforcement rings 206, as shown in FIG. Figure 9 As shown, a reinforcing net 207 is fixedly installed inside the transparent conveyor belt 203, and the reinforcing net 207 is fixedly connected to a plurality of reinforcing rings 206. In this embodiment, as shown in FIG. Figure 9 As shown, multiple reinforcement rings 206 are respectively located at the nodes of the longitudinal and transverse wires of the reinforcement net 207; specifically, by arranging the reinforcement rings 206 and the reinforcement net 207, when the conveyor belt 202 drives the transparent conveyor belt 203 for transportation, the reinforcement rings 206 in the socket holes are in contact with the rubber sleeve rod 204, which effectively prevents the conveyor belt 202 from pulling the transparent conveyor belt 203, causing the socket holes to be subjected to force and tearing and deformation. At the same time, the reinforcement net 207 connected to the reinforcement rings 206 is located inside the transparent conveyor belt 203, which can improve the structural strength of the transparent conveyor belt 203, make the force on the transparent conveyor belt 203 more uniform, and prevent the transparent conveyor belt 203 from being deformed during transportation.

[0046] like Figure 2As shown, an activated carbon air filter box 15 is provided on one side of the tunnel furnace base 1, one end of the air duct 14 is connected to the interior of the activated carbon air filter box 15, and an exhaust pipe 16 is fixedly installed on one side of the activated carbon air filter box 15; specifically, by providing the activated carbon air filter box 15, the mixed gas of moisture and exhaust gas extracted from the tunnel shell 3 by the suction blower 13 will be transported to the activated carbon air filter box 15 through the air duct 14, and the mixed gas will be adsorbed by impurities and moisture by the activated carbon particles inside the activated carbon air filter box 15, and at the same time the temperature of the mixed gas will be reduced, so that the purified, dried and cooled gas will eventually be discharged through the exhaust pipe 16, ensuring the cleanliness of the environment surrounding the tunnel furnace.

[0047] like Figure 10 As shown, an operation port and a cover are provided on one side of the tunnel shell 3, and an observation port covered with a transparent material is provided on the cover. It is an existing well-known technology and will not be described in detail here. Both side walls of the tunnel shell 3 are equipped with longitudinal linear guides 20, and a connecting frame 22 is fixedly connected to the transmission component of the longitudinal linear guide 20. A transverse linear guide 21 is installed at the bottom of the connecting frame 22. Both the longitudinal linear guide 20 and the transverse linear guide 21 are manual linear guides, and a cross rocker is provided at one end thereof. The cross rocker can drive the screw in the guide rail to rotate to move the transmission component. It is an existing well-known technology and will not be described in detail here. A top lamp tray 19 is installed on the transmission component of the transverse linear guide 21, and the top lamp tray 19 is connected to the top lamp tray 19. The lamp tray 6 has the same structural features and is also equipped with a lamp socket 8, an electrical plug 9 and an ultraviolet sterilization lamp 10. The irradiation surface of the top lamp tray 19 is downward, and the longitudinal linear guide 20 and the transverse linear guide 21 are both existing well-known technologies. The transmission components are allowed to move linearly along the track by starting the lead screw through the motor, which will not be elaborated here; specifically, the top lamp tray 19 can manually control the movement of the transmission components of the longitudinal linear guide 20 and the transverse linear guide 21 to achieve up and down lifting and left and right movement, adjust the irradiation position of the ultraviolet sterilization lamp 10 in the top lamp tray 19, thereby achieving better irradiation and sterilization effect, and being able to more clearly observe the conditions at various angles during the product conveying operation.

[0048] In summary: when in use: place the product on the conveyor belt assembly 2 for transportation, so that the product is sent into the tunnel shell 3 to stay, or reduce the conveying speed to make the product move slowly, so as to utilize the electric heating tube inside the tunnel furnace base 1 and the ultraviolet sterilization lamp 10 on the lamp tray 6 to heat, dry and sterilize the product, playing the dual role of sterilization and heating baking, the exhaust fan 13 will blow air regularly, extract the gas from the inside of the tunnel shell 3, so that the moisture and exhaust gas generated by baking are extracted, and the inside of the tunnel shell 3 is kept dry and clean, and at the same time, air flow is formed inside the tunnel furnace base 1, and passes through the periphery of the product through the air vents 208 on the transparent conveyor belt 203, using high heat The airflow dries the product, accelerating the drying speed of the product. The mixed gas of moisture and exhaust gas extracted from the tunnel shell 3 by the suction blower 13 is transported to the activated carbon filter box 15 through the air duct 14. The mixed gas will be adsorbed by impurities and moisture by the activated carbon particles inside the activated carbon filter box 15, while reducing the temperature of the mixed gas, so that the purified, dried and cooled gas is finally discharged through the exhaust pipe 16. The moisture generated by the baking and evaporation of the product condenses into dew and drips into the inside of the lamp tray 6 and flows into the drainage holes 11 along the slope, and is finally transported to the water storage tank 18 through the open water trough and the drainage pipe 17, thereby ensuring the cleanliness of the lamp tray 6 and the inside of the tunnel furnace base 1;

[0049] Maintenance of lamps: When it is necessary to maintain or replace the ultraviolet germicidal lamp 10, the drawer side cover 5 can be opened and the two lamp trays 6 can be quickly pulled out from the drawer frame 4, which provides convenience for the maintenance of the ultraviolet germicidal lamp 10 and the cleaning of the lamp tray 6 itself. Afterwards, the ultraviolet germicidal lamps 10 on the lamp socket 8 can be checked or replaced one by one. When the maintenance is completed, the lamp tray 6 can be reinserted into the drawer frame 4. The power plug 9 on one side of the lamp tray 6 will automatically connect with the power socket as the lamp tray 6 slides in the drawer frame 4, so that the ultraviolet germicidal lamp 10 is reconnected to the control circuit inside the tunnel furnace base 1. Finally, the drawer side cover 5 is closed to complete the installation;

[0050] Maintenance of the conveyor belt: When the transparent conveyor belt 203 shows problems of aging, cracking, or deformation after being baked at high temperature for a long time, the transparent tape 205 at the seam of the transparent conveyor belt 203 can be torn off to separate the two ends of the transparent conveyor belt 203. Then, one end of the transparent conveyor belt 203 can be lifted up. As the conveyor pad belt 202 runs, the various socket holes and the rubber sleeve rods 204 can be disengaged in turn until the transparent conveyor belt 203 is completely removed. Then, the operation can be reversed and a new transparent conveyor belt 203 can be installed between the two conveyor pad belts 202 to achieve quick replacement of the transparent conveyor belt 203.
