Description

Technical Field

[0001] The present invention relates to the technical field of germicidal lamps, and particularly to an ultraviolet germicidal lamp and a tunnel furnace using the ultraviolet germicidal lamp. Background Art

[0002] A tunnel furnace is a tunnel-type mechanical device that completes baking, heating, etc. of objects through heat conduction, convection, and radiation. It is widely used in many industries such as food processing, chemical industry, metallurgy, building materials, electronics, and medicine, and has the characteristics of high efficiency and environmental protection. When the tunnel furnace works, the heat generated by the heating element is transferred to the material or product through heat conduction, convection, and radiation. The material enters from the inlet end of the tunnel furnace under the drive of the conveying system, passes through different temperature zones such as the preheating zone, heating zone, and heat preservation zone, completes processes such as baking, drying, and curing, and finally is sent out from the outlet end.

[0003] Existing tunnel furnaces generally heat products through built-in heating tubes, and their defects are as follows: The existing technology equipment can only provide heating and baking functions and cannot provide a sterilization effect, while some products have high requirements for the sterilization function, and the built-in heating tubes need to be replaced frequently. Each replacement requires disassembling the chains and conveyor belts of the equipment, which is rather troublesome. Therefore, an ultraviolet germicidal lamp and a tunnel furnace using the ultraviolet germicidal lamp are proposed. Summary of the Invention

The output shafts of the two conveyor motors are respectively drivingly connected to the two conveyor rollers.

[0008] Further, a plurality of uniformly distributed rubber sleeve rods are fixedly installed on the conveyor cushion belts. A plurality of socket holes adapted to the rubber sleeve rods are opened on both sides of the transparent conveyor belt.

[0009] Further, a plurality of uniformly distributed air holes are opened on the transparent conveyor belt. An air extraction and supply fan is fixedly installed on the top of the tunnel housing. The air inlet of the air extraction and supply fan is communicated with the inside of the tunnel housing. An air duct is fixedly installed at the air outlet of the air extraction and supply fan.

[0010] Further, a plurality of uniformly distributed drain holes are opened on the inner wall of the bottom of the lamp tray. The inner wall of the bottom of the lamp tray is a slope structure inclined towards the drain holes. Open-top water receiving troughs arranged horizontally are fixedly installed inside the two drawer racks. The open-top water receiving troughs on the same side are located at the bottom of the plurality of drain holes. Two drain pipes are fixedly installed on one side of the tunnel furnace base. One ends of the two drain pipes respectively extend into the two drawer racks and are respectively communicated with the inside of the two open-top water receiving troughs. A water storage tank is fixedly installed on one side of the bottom of the tunnel furnace base. The water storage tank is located below the bottom ends of the two drain pipes.

[0011] Furthermore, reinforcing rings are fixedly installed inside the socket holes. A plurality of the rubber sleeve rods on the same side are respectively inserted into the inside of the plurality of reinforcing rings. A reinforcing net is fixedly installed inside the transparent conveyor belt, and the reinforcing net is fixedly connected to the plurality of reinforcing rings.

[0012] Furthermore, an activated carbon air filter box is arranged on one side of the tunnel furnace base. One end of the air delivery pipe is communicated with the inside of the activated carbon air filter box, and an exhaust pipe is fixedly installed on one side of the activated carbon air filter box.

[0013] 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. 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 provided with a lamp socket, a power connection plug and an ultraviolet germicidal lamp. The irradiation surface of the top lamp tray faces downward.

[0014] The beneficial effects of the present invention are as follows: 1. When the present invention is in use, the lamp tray loaded with the ultraviolet germicidal lamp is placed inside the tunnel furnace. The heating tubes built in the tunnel furnace itself can heat and dry the products conveyed on the tunnel furnace, while the ultraviolet germicidal lamp inside the lamp tray can sterilize the products being dried, so that the products are subjected to double treatments of heating and sterilization. At the same time, the ultraviolet germicidal lamp is integrated in the lamp tray by a fixed plug-in method, and the integrated structure of the drawer-type push-pull tray facilitates taking out the lamp tray from the tunnel furnace for maintenance; 2. When the present invention is under maintenance, the two lamp trays are quickly pulled out from the drawer rack, which facilitates the maintenance of the ultraviolet germicidal lamp and the cleaning of the lamp tray itself. When the maintenance is completed, the lamp tray is reinserted into the drawer rack. The power connection plug on one side of the lamp tray will automatically be inserted into the power connection socket as the lamp tray slides in the drawer rack, so that the ultraviolet germicidal lamp is reconnected to the control circuit inside the tunnel furnace base. Finally, closing the drawer side flip cover can complete the installation. The operation is simple and fast. The installation methods of the lamp and the heating element are improved, greatly improving the later maintenance efficiency and saving the maintenance cost; 3. By providing the transparent conveyor belt, the conveyor motor on one side of the tunnel furnace base synchronously drives the two conveyor rollers to rotate in the same direction, thereby driving the conveyor belts on both sides to operate, and then driving the products placed above the transparent conveyor belt to move forward through the transparent conveyor belt in the middle. The transparent conveyor belt made of transparent material will not cause too much blockage and reflection to the ultraviolet rays emitted by the ultraviolet germicidal lamp below, enabling the sterilization and disinfection function of the ultraviolet germicidal lamp to take effect normally; 4. By providing a rubber sleeve rod in the present invention, when problems such as aging, cracking, and deformation occur to the transparent conveyor belt under long-term high-temperature baking, the transparent tape at the joint of the transparent conveyor belt can be torn off to separate the two ends of the transparent conveyor belt. Then, one end of the transparent conveyor belt is lifted. As the conveyor pad belt runs, each socket hole is sequentially disengaged from the rubber sleeve rod until the transparent conveyor belt is completely removed. Then, the reverse operation is performed to install a new transparent conveyor belt between the two conveyor pad belts, realizing the rapid replacement of the transparent conveyor belt. 5. By providing an air extraction and blowing fan in the present invention, when baking and sterilizing the product, the air extraction and blowing fan will blow air regularly, extracting the gas from the inside of the tunnel housing, so that the moisture and waste gas generated by baking are extracted, keeping the inside of the tunnel housing dry and clean. At the same time, an air flow is formed inside the tunnel furnace base and passes through the periphery of the product through the ventilation holes on the transparent conveyor belt, using the high-temperature air flow to air-dry the product and accelerating the drying speed of the product. 6. By providing drain holes in the present invention, when using the lamp tray equipped with ultraviolet germicidal lamps to sterilize the product, the water vapor evaporated and generated by the baking of the product condenses into dew drops and falls into the inside of the lamp tray and flows along the inclined plane into each drain hole, and finally is transported to the water storage tank through the open water receiving tank and the drain pipe, thus ensuring the cleanliness of the inside of the lamp tray and the tunnel furnace base. 7. By providing a reinforcing ring and a reinforcing net in the present invention, when the conveyor pad belt and the transparent conveyor belt are transporting, the reinforcing ring in the socket hole contacts the rubber sleeve rod, effectively preventing the socket hole from being torn and deformed when the conveyor pad belt pulls 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 transportation process. 8. By providing an activated carbon air filter box in the present invention, the gas mixture of moisture and waste gas extracted by the air extraction and blowing fan from the tunnel housing will be transported to the activated carbon air filter box through the air duct. The gas mixture will be adsorbed by the activated carbon particles inside the activated carbon air filter box to remove impurities and moisture, and at the same time reduce the temperature of the gas mixture, so that the purified, dried, and cooled gas is finally discharged through the exhaust pipe, ensuring the cleanliness of the surrounding environment of the tunnel furnace.

[0020] As Figures 1 to 10 shown, an ultraviolet germicidal lamp and a tunnel furnace using the ultraviolet germicidal lamp include a lamp tray 6. As Figure 5 , Figure 6 shown, a guide frame 7 is fixedly installed on the top of the lamp tray 6, a lamp socket 8 is fixedly installed inside the lamp tray 6, and a plurality of evenly distributed ultraviolet germicidal lamps 10 are fixedly inserted on the top of the lamp socket 8. The lamp tray 6 is used to load the ultraviolet germicidal lamps 10 and is placed in the tunnel furnace to provide the functions of drying and sterilizing the conveyed products. A power connection plug 9 is fixedly installed on one side of the lamp tray 6, and the power connection plug 9 is electrically connected to the lamp socket 8; specifically, when the ultraviolet germicidal lamp is in use, the lamp tray 6 loaded with the ultraviolet germicidal lamps 10 can be placed inside the tunnel furnace. The heating tubes built in the tunnel furnace itself can heat and dry the products conveyed on the tunnel furnace, while the ultraviolet germicidal lamps 10 inside the lamp tray 6 can sterilize the products during drying, enabling the products to be subjected to double treatment of heating and sterilization. At the same time, the ultraviolet germicidal lamps 10 are integrated in the lamp tray 6 by a fixed plug-in method, and the integrated structure of the drawer-type push-pull tray facilitates the removal of the lamp tray 6 from the tunnel furnace for maintenance.

[0021] A tunnel furnace using an ultraviolet germicidal lamp includes a tunnel furnace base 1. In this embodiment, common electric heating tubes on the market are arranged inside the tunnel furnace base 1. As Figure 1 shown, a conveyor belt assembly 2 is driven and installed inside the tunnel furnace base 1. A tunnel housing 3 is fixedly installed on the top of the tunnel furnace base 1. As Figure 4 shown, two drawer racks 4 are fixedly installed inside the tunnel furnace base 1. As Figure 3 shown, two drawer holes are formed on one side of the tunnel furnace base 1, and the positions of the two drawer holes correspond to the positions of the two drawer racks 4 respectively. Drawer side flip covers 5 are rotatably installed inside the drawer holes. As Figure 4As shown in the figure, two lamp trays 6 are respectively placed inside two drawer racks 4. Two guide racks 7 are respectively slidably installed inside two drawer racks 4. Both two drawer racks 4 are located at the bottom of the tunnel housing 3. Inside each drawer rack 4, there is a power connection socket fixedly installed and adapted to the power connection plug 9. Specifically, when this tunnel furnace is in use, the product is placed on the conveyor belt assembly 2 for conveyance, so that the product is sent into the tunnel housing 3 and stays there, or the conveyor speed is reduced to make the product move forward slowly. Thus, the electric heating tubes inside the tunnel furnace base 1 and the ultraviolet germicidal lamps 10 on the lamp trays 6 are used to heat, dry, sterilize and disinfect the product, playing a dual role of sterilization and heating and baking. At the same time, the ultraviolet germicidal lamps 10 are integrated in the lamp trays 6. When it is necessary to maintain and replace the ultraviolet germicidal lamps 10, the drawer side flip cover 5 can be opened, and the two lamp trays 6 can be quickly pulled out from the drawer racks 4, which provides convenience for the maintenance of the ultraviolet germicidal lamps 10 and the cleaning of the lamp trays 6 themselves. Then, the ultraviolet germicidal lamps 10 on the lamp socket connectors 8 are inspected or replaced one by one. When the maintenance is completed, the lamp trays 6 are reinserted into the drawer racks 4. The power connection plug 9 on one side of the lamp tray 6 will automatically be inserted into the power connection 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, closing the drawer side flip cover 5 completes the installation. The operation is simple and fast, improving the installation method of the lamps and heating elements, greatly improving the later maintenance efficiency and saving the maintenance cost.

[0022] As Figure 7 shown in the figure, the conveyor belt assembly 2 includes two conveyor rollers 201 that are drivingly installed inside the tunnel furnace base 1. The conveyor rollers 201 are both horizontally arranged and parallel to each other. At both ends of the two conveyor rollers 201, there are conveyor cushion belts 202 tensioned. In this embodiment, at one end of the two conveyor rollers 201 on the same side, there is the same conveyor cushion belt 202 tensioned, and at the other end of the two conveyor rollers 201, there is a second conveyor cushion belt 202 tensioned. Between the two conveyor cushion belts 202, there is the same transparent conveyor belt 203. Both two lamp trays 6 are located inside the transparent conveyor belt 203. As Figure 2 shown in the figure, on one side of the tunnel furnace base 1, there are two conveyor motors 12 fixedly installed. The output shafts of the two conveyor motors 12 are respectively drivingly connected to the two conveyor rollers 201. Specifically, by setting the transparent conveyor belt 203, the conveyor motors 12 on one side of the tunnel furnace base 1 will synchronously drive the two conveyor rollers 201 to rotate in the same direction, thereby driving the conveyor cushion belts 202 on both sides to operate, and further driving the product placed above the transparent conveyor belt 203 to move forward through the transparent conveyor belt 203 in the middle. The transparent conveyor belt 203 made of transparent material will not cause excessive blocking and reflection to the ultraviolet rays emitted by the ultraviolet germicidal lamps 10 below, enabling the sterilization and disinfection function of the ultraviolet germicidal lamps 10 to take effect normally.

[0023] AsFigure 8 As shown in the figure, a plurality of uniformly distributed rubber sleeve rods 204 are fixedly installed on the conveying cushion belt 202. A plurality of socket holes adapted to the rubber sleeve rods 204 are provided on both sides of the transparent conveyor belt 203. A plurality of rubber sleeve rods 204 on the same side are respectively inserted into the plurality of socket holes. Transparent tapes 205 are bonded at the joints at both ends of the transparent conveyor belt 203. Specifically, by setting the rubber sleeve rods 204, the cooperation between the rubber sleeve rods 204 and the socket holes on both sides of the transparent conveyor belt 203 enables the transparent conveyor belt 203 to be separated from the conveying cushion belts 202 on both sides. When the transparent conveyor belt 203 has problems such as aging, cracking, and deformation under long-term high-temperature baking, the transparent tape 205 at the joint 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 is lifted. As the conveying cushion belt 202 rotates, each socket hole is successively disengaged from the rubber sleeve rod 204 until the transparent conveyor belt 203 is completely removed. Then, the reverse operation is performed to install a new transparent conveyor belt 203 between the two conveying cushion belts 202, realizing the rapid replacement of the transparent conveyor belt 203.

[0024] As Figure 8 shown, a plurality of uniformly distributed ventilation holes 208 are provided in the transparent conveyor belt 203. As Figure 1 shown, an air extraction and delivery fan 13 is fixedly installed on the top of the tunnel housing 3. The air inlet of the air extraction and delivery fan 13 is communicated with the inside of the tunnel housing 3. An air delivery pipe 14 is fixedly installed at the air outlet of the air extraction and delivery fan 13. Specifically, by setting the air extraction and delivery fan 13, during the baking and sterilization treatment of the product, the air extraction and delivery fan 13 blows air regularly, extracts the gas from the inside of the tunnel housing 3, so that the moisture and waste gas generated by baking are extracted, keeping the inside of the tunnel housing 3 dry and clean. At the same time, an air flow is formed inside the tunnel furnace base 1 and passes through the periphery of the product through the ventilation holes 208 on the transparent conveyor belt 203, and the product is air-dried by the high-temperature air flow, accelerating the drying speed of the product.

[0025] As Figure 5 、 Figure 6 shown, a plurality of uniformly distributed drain holes 11 are provided on the bottom inner wall of the lamp tray 6. The bottom inner wall of the lamp tray 6 is a slope structure inclined towards the drain holes 11. As Figure 4 shown, open water receiving troughs arranged horizontally are fixedly installed inside the drawer racks 4. The open water receiving troughs on the same side are located at the bottom of the plurality of drain holes 11. As Figure 2As shown in the figure, two drain pipes 17 are fixedly installed on one side of the base 1 of the tunnel furnace. One ends of the two drain pipes 17 respectively extend into the interiors of the two drawer racks 4 and are respectively communicated with the interiors of the two open water receiving grooves. One side of the bottom of the base 1 of the tunnel furnace is fixedly installed with a water storage tank 18. The water storage tank 18 is located below the bottoms of the two drain pipes 17. Specifically, by providing the drain holes 11, when the product is sterilized using the lamp tray 6 loaded with the ultraviolet germicidal lamp 10, the moisture generated by the evaporation of the product during baking condenses into dew drops, which fall into the interior of the lamp tray 6 and flow along the inclined plane into the respective drain holes 11, and finally are transported to the water storage tank 18 through the open water receiving groove and the drain pipe 17, thereby ensuring the cleanliness of the interior of the lamp tray 6 and the base 1 of the tunnel furnace.

[0026] As Figure 8 shown, reinforcing rings 206 are fixedly installed inside the socket holes. A plurality of rubber sleeve rods 204 on the same side are respectively inserted into the interiors of the plurality of reinforcing rings 206. As Figure 9 shown, a reinforcing mesh 207 is fixedly installed inside the transparent conveyor belt 203. The reinforcing mesh 207 is fixedly connected to the plurality of reinforcing rings 206. In this embodiment, as Figure 9 shown, the plurality of reinforcing rings 206 are respectively located at the nodes of the longitudinal and transverse filaments of the reinforcing mesh 207. Specifically, by providing the reinforcing rings 206 and the reinforcing mesh 207, when the conveying cushion belt 202 drives the transparent conveyor belt 203 to convey, the reinforcing rings 206 in the socket holes come into contact with the rubber sleeve rods 204, effectively preventing the problem that when the conveying cushion belt 202 pulls the transparent conveyor belt 203, the socket holes are stressed and torn or deformed. At the same time, the reinforcing mesh 207 connected to the reinforcing 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 problem of deformation of the transparent conveyor belt 203 during the conveying process.

[0027] As Figure 2 shown, an activated carbon air filter box 15 is provided on one side of the base 1 of the tunnel furnace. One end of the air duct 14 is communicated with the interior of the activated carbon air filter box 15. 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 gas mixture of moisture and waste gas extracted by the suction fan 13 from the tunnel housing 3 will be transported to the activated carbon air filter box 15 through the air duct 14. The gas mixture will be adsorbed by the activated carbon particles inside the activated carbon air filter box 15 to remove impurities and moisture, and at the same time reduce the temperature of the gas mixture, so that the purified, dried and cooled gas is finally discharged through the exhaust pipe 16, ensuring the cleanliness of the surrounding environment of the tunnel furnace.

[0028] As Figure 10As shown in the figure, an operation opening is provided on one side of the tunnel housing 3 and is equipped with a cover plate. An observation opening covered with a transparent material is provided on the cover plate. This is a well-known prior art and will not be elaborated here. Longitudinal linear guides 20 are installed on both side walls of the tunnel housing 3. 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 adopt manual linear guides. A cross rocker is provided at one end. The cross rocker can drive the screw rod in the guide rail to rotate to move the transmission component. This is a well-known prior art and will not be elaborated here. A top lamp tray 19 is installed on the transmission component of the transverse linear guide 21. The top lamp tray 19 has the same structural features as the lamp tray 6, and is also equipped with a lamp socket 8, a power connection plug 9, and an ultraviolet germicidal lamp 10. The irradiation surface of the top lamp tray 19 faces downward. Both the longitudinal linear guide 20 and the transverse linear guide 21 are well-known prior arts. The screw rod is started by a motor to make the transmission component move linearly along the track, 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 realize up and down lifting and left and right movement, and adjust the irradiation position of the ultraviolet germicidal lamp 10 in the top lamp tray 19, so as to achieve a better irradiation and sterilization effect and be able to more clearly observe the conditions of each angle during the product conveying operation process.

[0029] 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 housing 3 and stays, or reduce the conveyor speed to make the product move slowly, so as to use the electric heating tubes inside the tunnel furnace base 1 and the ultraviolet germicidal lamp 10 on the lamp tray 6 to heat, dry, sterilize and disinfect the product, playing a dual role of sterilization and heating and baking. The air extraction and blowing fan 13 will blow air regularly, extract the gas from the inside of the tunnel housing 3, so that the moisture and waste gas generated by baking are extracted, keeping the inside of the tunnel housing 3 dry and clean. At the same time, an air flow is formed inside the tunnel furnace base 1 and passes through the air holes 208 on the transparent conveyor belt 203 through the periphery of the product, and the product is air-dried by the high-temperature air flow to accelerate the drying speed of the product. The mixed gas of moisture and waste gas extracted by the air extraction and blowing fan 13 from the tunnel housing 3 will be transported to the activated carbon air filter box 15 through the air duct 14. The mixed gas will be adsorbed by the activated carbon particles inside the activated carbon air filter box 15 to remove impurities and moisture, and at the same time reduce the temperature of the mixed gas, so that the purified, dried and cooled gas is finally discharged through the exhaust pipe 16. The moisture evaporated and generated by the product baking condenses into dew and drips into the inside of the lamp tray 6 and flows along the inclined surface into each drain hole 11, and finally is transported to the water storage tank 18 through the open water receiving tank and the drain pipe 17, thus ensuring the cleanliness inside the lamp tray 6 and the tunnel furnace base 1; Maintenance of the lamp: When maintenance and replacement of the ultraviolet germicidal lamp 10 are required, the drawer side flip cover 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 lamp 10 and the cleaning of the lamp tray 6 itself. Then, the ultraviolet germicidal lamps 10 on the lamp socket 8 are inspected or replaced one by one. When the maintenance is completed, the lamp tray 6 is reinserted into the drawer rack 4. The power plug 9 on one side of the lamp tray 6 will automatically plug into the power socket as the lamp tray 6 slides in the drawer rack 4, reconnecting the ultraviolet germicidal lamp 10 to the control circuit inside the tunnel furnace base 1. Finally, closing the drawer side flip cover 5 completes the installation; Maintenance of the conveyor belt: When problems such as aging, cracking, and deformation occur in the transparent conveyor belt 203 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. Then, one end of the transparent conveyor belt 203 is lifted, and as the conveyor pad belt 202 rotates, each socket hole is sequentially disengaged from the rubber sleeve rod 204 until the transparent conveyor belt 203 is completely removed. Then, operate in reverse to install the new transparent conveyor belt 203 between the two conveyor pad belts 202 to achieve rapid replacement of the transparent conveyor belt 203.
