Description

Technical Field

[0001] The utility model relates to the technical field of tunnel drying furnaces, in particular to a ground rail type tunnel drying furnace device. Background Art

[0002] Tunnel drying furnace is an industrial equipment that heats and dries materials through hot air. Due to its tunnel structure, the materials are continuously moved in the furnace through transmission devices such as conveyor belts or chains, and are heated and dried by hot air at the same time, thereby achieving material drying.

[0003] The structure of the existing tunnel drying furnace is usually set as an integrated structure, so that the heat-generating furnace body and the tunnel-type outer shell cannot be separated, which makes it troublesome and time-consuming to clean or repair the furnace body, which is not conducive to the cleaning and maintenance of the tunnel drying furnace; in addition, since the tunnel drying furnace is usually in use for a long time, the moisture inside the material in the tunnel drying furnace evaporates due to the high temperature to produce a large amount of water vapor, and the water vapor is easy to accumulate in the tunnel furnace and is not easy to be quickly discharged from the device, so the circulation system in the tunnel drying furnace will bring the water vapor back into the furnace, resulting in a slower drying speed of the material. Utility Model Content

[0004] The purpose of the utility model is to provide a ground rail type tunnel drying furnace device to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a ground rail type tunnel drying furnace device, comprising a ground rail, the top end of the ground rail is slidably connected to an outer shell, the top cover of the outer shell is provided with a top cover, a drying rod is provided inside the top cover, drainage pipes are provided on both sides of the top cover, a plurality of heat sinks are fixedly connected to the outer wall of the middle section of the drainage pipe, a water collecting cylinder is passed through the bottom end of the drainage pipe, a bottom box is provided inside the outer shell, a cavity is provided inside the bottom box, an electric heater is fixedly installed at the bottom of the inner side of the cavity, a ventilation duct is provided at the bottom end of the cavity, a sprocket is installed at the top of the inner side of the cavity, a chain is meshed and connected to the outer side of the sprocket, the top of the chain is movably connected to a conveyor belt, a hydraulic cylinder is installed at the bottom of the bottom box, a plurality of hot air outlets are provided at the top of the bottom box, and two cold air inlets are provided on both side walls of the bottom box.

[0006] Preferably, the top end of the top cover is movably threadedly connected with a clamping plate, the drying rod is engaged with the clamping plate, and the drying rod is movably connected to the top cover through the clamping plate.

[0007] Preferably, side covers are engaged with both side walls of the top cover, and the top end of the drainage tube is connected to the side covers through.

[0008] Preferably, a negative pressure fan is installed inside the side cover, and the drainage pipe is connected to the inside of the top cover through the side cover.

[0009] Preferably, the interior of the water collecting cylinder is communicated with the interior of the drainage pipe, and a screw cap is engaged with a movable thread at the bottom end of the water collecting cylinder.

[0010] Preferably, the hot air outlet and the cold air inlet are both communicated with the interior of the cavity, the cold air inlet is communicated with the interior of the ventilation duct, and the bottom end of the drainage pipe is movably connected to the cold air inlet.

[0011] Preferably, the output end of the hydraulic cylinder is engaged with an inner wall of one side of the shell, and the shell is connected to the bottom box movable cover through the hydraulic cylinder and the ground rail.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. The local rail-type tunnel drying furnace device has a split-type shell and bottom box, as well as a floor rail and a hydraulic cylinder. When the drying furnace device needs to be cleaned or repaired, the piston rod at the output end of the hydraulic cylinder on the bottom box can push the shell outward, so that the shell slides away from the bottom box along the floor rail, so that the bottom box part of the drying furnace device is separated from the shell part, thereby facilitating the cleaning or maintenance of the bottom box or the internal structure of the shell.

[0014] 2. The local rail-type tunnel drying furnace device uses a top cover, drying rods, drainage pipes and water collecting cylinders, so that the water vapor generated in the drying furnace device can first be absorbed and dried by the drying rods in the top cover, and then the water vapor entrained by the high-temperature heat will enter the drainage pipe. Through the rapid heat dissipation of the heat sink, the water vapor is condensed into liquid water on the inner wall of the drainage pipe and collected in the water collecting cylinder, making it difficult for water vapor to enter the circulation system of the drying furnace, thereby reducing the probability of water vapor returning to the furnace and improving the drying speed of the material in the furnace.

[0024] Specifically, two ground rails 9 are provided, and the ends are both equipped with limiting structures, so that the shell 1 can maintain the connection with the ground rails 9, avoiding the situation that the shell 1 cannot be reset with the bottom box 10 due to derailment. One end of the shell 1 is provided with an opening, the interior is hollowed out, and the other end is in a closed state, so that the shell 1 can surround the heat as much as possible, so that the material entering the drying furnace device can quickly absorb the heat, the interior of the top cover 2 is communicated with the interior of the shell 1, so that the heat can carry water vapor into the top cover 2, and the drying rod 14 is composed of a solid desiccant, which can absorb most of the water vapor, so that the shell 1 and the top cover 2 can remain dry and reduce the accumulation of water vapor in the top cover 2. The function of the drainage pipe 5 is to facilitate the conduction of heat with water vapor Out of the device, the water vapor is then condensed and liquefied in cooperation with the heat sink 6, so that the water vapor generated in the furnace is not easily returned to the furnace with the circulation system, thereby helping to improve the drying efficiency of the device for the material. The water collecting cylinder 7 is located at the bottom of the drainage pipe 5, and the top is not closed, so that the liquid water condensed from the water vapor on the inner wall of the drainage pipe 5 can smoothly enter the water collecting cylinder 7 and be collected, thereby realizing the rapid discharge of water vapor in the furnace. There are two sprockets 15, one of which is connected to the output end of the driving mechanism, so that the chain 16 can drive the conveyor belt 11 to circulate on the top of the bottom box 10, thereby realizing the circulation of the material in the device and drying it. The inner walls of the hot air outlet 12 and the cold air inlet 13 are embedded with protective nets to prevent debris from entering the furnace through the holes.

[0025] Furthermore, the top of the top cover 2 is movably threadedly connected with a clamping plate 3, and the drying rod 14 is clamped and connected to the clamping plate 3. The drying rod 14 is movably connected to the top cover 2 through the clamping plate 3. The function of the clamping plate 3 is to realize the integration of multiple drying rods 14 in the top cover 2, so that multiple drying rods 14 can be replaced in time. There is a large distance between the multiple drying rods 14, so that water vapor can fully contact the drying rod 14 and be absorbed by the drying rod 14.

[0026] Furthermore, side covers 4 are engaged with both side walls of the top cover 2, and the top end of the drainage tube 5 is connected to the side covers 4. The function of the side covers 4 is to enable the top cover 2 to communicate with the interior of the drainage tube 5, thereby facilitating water vapor to enter the drainage tube 5 from the top cover 2.

[0027] Furthermore, a negative pressure fan 21 is installed inside the side cover 4, and the drainage pipe 5 is connected to the inside of the top cover 2 through the side cover 4. The function of the negative pressure fan 21 is to accelerate the heat and entrained water vapor in the top cover 2 to quickly enter the side cover 4, thereby reducing the accumulation of water vapor in the outer shell 1 and the top cover 2.

[0028] Furthermore, the interior of the water collecting cylinder 7 is connected to the interior of the drainage tube 5, and the bottom end of the water collecting cylinder 7 is engaged with a screw cap 8 by a movable thread. The function of the screw cap 8 is to facilitate the direct opening of the bottom of the water collecting cylinder 7, thereby realizing the timely discharge of the liquid water collected in the water collecting cylinder 7.

[0029] Furthermore, the hot air outlet 12 and the cold air inlet 13 are both communicated with the interior of the cavity 18, the cold air inlet 13 is communicated with the interior of the ventilation duct 19, the bottom end of the drainage pipe 5 is movably connected to the cold air inlet 13, and the cold air inlet 13 is located at the end of the ventilation duct 19, so that the airflow blown into the drainage pipe 5 by the negative pressure fan 21 can enter the cavity 18 through the ventilation duct 19, thereby facilitating the heat in the cavity 18 to quickly rise to the hot air outlet 12, thereby accelerating the airflow circulation speed in the drying furnace device.

[0030] Furthermore, the output end of the hydraulic cylinder 20 is engaged with the inner wall of one side of the outer shell 1, and the outer shell 1 is connected to the movable cover of the bottom box 10 through the hydraulic cylinder 20 and the ground rail 9. The function of the hydraulic cylinder 20 is to push the outer shell 1 through the piston rod so that the outer shell 1 can be separated from the bottom box 10, thereby facilitating the cleaning and maintenance of the bottom box 10 and the outer shell 1.

[0031] The method of using this embodiment is as follows: when using the local rail 9-type tunnel drying furnace device, first connect the device to an external power supply so that the sprocket 15 is driven by the driving mechanism to rotate, driving the chain 16 and the conveyor belt 11 on the top of the chain 16 to circulate at the top of the bottom box 10, so that the material on the conveyor belt 11 circulates with the conveyor belt 11 in the outer shell 1, and then start the negative pressure fan 21 so that the negative pressure fan 21 blows air from the drainage pipe 5 into the cold air inlet 13, and then enters the cavity 18 through the ventilation duct 19, so that the heat generated by the electric heater 17 running in the cavity 18 is blown to the hot air outlet 12 on the top of the cavity 18, so that the circulating material on the bottom box 10 can absorb the heat blown out from the hot air outlet 12, and as the temperature in the outer shell 1 increases, the water vapor generated by the evaporation of water inside the material will enter the top cover 2 , and contacts the drying rod 14 in the top cover 2, so that the drying rod 14 absorbs most of the water vapor, and a small part of the water vapor is entrained by the heat and is blown into the drainage pipe 5 from the top cover 2 under the drive of the negative pressure fan 21, and then dissipates heat through the heat sink 6 on the outer wall of the drainage pipe 5, condenses into liquid water on the inner wall of the drainage pipe 5, and then flows into the water collecting tube 7 along the inner wall of the drainage pipe 5 to be collected, while the air flow continues to enter the ventilation duct 19 through the cold air inlet 13. When it is necessary to clean or inspect the inside of the outer shell 1 or the bottom box 10, the hydraulic cylinder 20 can be started so that the hydraulic cylinder 20 pushes the outer shell 1 along the ground rail 9 to move away from the bottom box 10, so that the bottom box 10 slides out from the inside of the outer shell 1 until the bottom box 10 is completely exposed from the inside of the outer shell 1. The bottom box 10 and the inside of the outer shell 1 can be cleaned or inspected.
