Abstract
Description
Technical Field
[0001] This utility model relates to a drying oven, specifically a high-efficiency drying and volatilization oven, belonging to the technical field of material drying equipment. Background Technology
[0002] A drying and volatile matter evaporation furnace is a core piece of equipment that uses hot airflow or a heat transfer medium to dry materials and remove volatiles (such as water, organic solvents, and volatile impurities). Some drying and volatile matter evaporation furnaces use hot air for drying, which is one of the most common drying methods. The principle of hot air drying is to heat the air to form a high-temperature airflow, and use the contact between the hot air and the material to transfer heat, so that the moisture or volatile substances in the material evaporate and are discharged, thereby achieving drying.
[0003] However, traditional drying and volatilization furnaces have some shortcomings. For example, after one drying cycle, the hot air is directly discharged to the outside of the drying furnace. The discharged hot air contains a lot of residual heat, resulting in serious waste of heat source. According to statistics, the heat loss caused by the direct discharge of hot air in traditional external exhaust drying furnaces can reach 30%-50%, which not only increases energy consumption but also leads to poor environmental performance. Utility Model Content
[0004] The purpose of this invention is to provide a high-efficiency drying and volatilization furnace to solve the above problems, which can realize the recycling of hot air, effectively reduce energy consumption, and improve the environmental friendliness of use.
[0005] This utility model achieves the above-mentioned objectives through the following technical solution: a high-efficiency drying and volatilization furnace, comprising a furnace body, a placement structure on the furnace body, a drying structure on the furnace body, the drying structure including an air inlet pipe and air inlet holes, an air inlet pipe fixedly connected to the furnace body, an air inlet pipe having multiple air inlet holes, a connecting sleeve fixedly connected to one end of the air inlet pipe, a valve block rotatably connected inside the connecting sleeve, a first through hole inside the valve block, two second through holes inside the valve block, a square tube fixedly connected to the connecting sleeve, an outer frame installed on the square tube, multiple heating wires installed on the outer frame, a fan installed on the square tube, an air outlet pipe fixedly connected to the square tube, the air outlet pipe fixedly connected to the furnace body, an air outlet pipe having multiple air outlet holes, a driving structure on the connecting sleeve, and a humidity sensor installed on the furnace body.
[0006] Preferably, the plurality of air inlets are linearly and equidistantly distributed, and the plurality of air outlets are linearly and equidistantly distributed.
[0007] Preferably, the cross-section of the second through hole is L-shaped, and the two second through holes are symmetrically distributed about the middle of the first through hole.
[0008] Preferably, two air guide pipes are fixedly connected to the top side of the valve block, and the air guide pipes are in an L-shaped structure.
[0009] Preferably, the drive structure includes a support plate and a first motor. The support plate is fixedly connected to the connecting sleeve, the first motor is mounted on the support plate, a first synchronous pulley is fixedly connected to the output shaft of the first motor, a second synchronous pulley is fixedly connected to the valve block, and the same synchronous belt is wound between the first synchronous pulley and the second synchronous pulley.
[0010] Preferably, the placement structure includes a main shaft and a tray. The main shaft is rotatably connected to the furnace body, and multiple trays are fixedly connected to the main shaft. Two storage trays are placed on the top side of the trays.
[0011] Preferably, a second motor is installed on the furnace body, and the output shaft of the second motor is fixedly connected to the top end of the main shaft.
[0012] Preferably, the tray has an outwardly extending protrusion near the top, and the multiple trays are linearly and equidistantly distributed.
[0013] Preferably, the furnace body is equipped with a sealed door, and four support legs are fixedly connected to the bottom of the furnace body.
[0014] The beneficial effects of this utility model are as follows: During use, the material to be dried and volatilized can be placed using the placement structure. When drying is required, the fan can be activated, and gas will be blown out from multiple air outlets under the action of the fan. During the gas flow, it will be heated by multiple heating wires. The hot air blowing onto the surface of the material will achieve drying and volatilization. Furthermore, under the action of the fan, the hot air with a certain amount of residual heat will enter the interior of the air inlet pipe through multiple air inlets, then enter the interior of the valve block, and flow into the interior of the square tube through the first through hole. From there, it enters the interior of the outlet pipe, and finally exits from multiple outlets... The air is blown out through the vents, thus realizing the recycling of hot air, effectively saving energy consumption and improving the environmental friendliness of use. As the drying time increases, the humidity of the air inside the furnace increases. When the humidity sensor detects that the air is relatively humid, the drive structure will drive the valve block to rotate 90 degrees. After the valve block rotates 90 degrees, the external air will enter the interior of the valve block through one of the second through holes and eventually enter the interior of the furnace. The humid air inside the furnace will eventually be discharged through the other second through hole, thus avoiding the situation where the drying and volatilization effect is poor due to high air humidity, and effectively ensuring the drying and volatilization effect of the material.

Detailed Implementation
[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figures 1-6As shown, a high-efficiency drying and volatilization furnace includes a furnace body 1, a placement structure 4 on the furnace body 1, and a drying structure 2 on the furnace body 1. The drying structure 2 includes an air inlet pipe 201 and air inlet holes 202. The air inlet pipe 201 is fixedly connected to the furnace body 1, and the air inlet pipe 201 has multiple air inlet holes 202. A connecting sleeve 203 is fixedly connected to one end of the air inlet pipe 201. A valve block 204 is rotatably connected inside the connecting sleeve 203. The valve block 204 has a first through hole 205 inside. The interior of 04 has two second through holes 206. A square tube 207 is fixedly connected to the connecting sleeve 203. An outer frame 208 is installed on the square tube 207. Multiple heating wires 209 are installed on the outer frame 208. A fan 210 is installed on the square tube 207. An exhaust pipe 211 is fixedly connected to the square tube 207. The exhaust pipe 211 is fixedly connected to the furnace body 1. Multiple exhaust holes 212 are provided on the exhaust pipe 211. A driving structure 3 is provided on the connecting sleeve 203. A humidity sensor 5 is installed on the furnace body 1.
[0024] As a technical optimization of this utility model, the multiple air inlets 202 are linearly and equidistantly distributed, so that hot air from different positions inside the furnace body 1 can enter the air inlet pipe 201 for recycling. The multiple air outlets 212 are linearly and equidistantly distributed, so that hot air can be blown out from the multiple air outlets 212, thereby blowing the hot air more evenly onto the material.
[0025] As a technical optimization of this utility model, the cross-section of the second through hole 206 is L-shaped, so that dry gas from the outside can enter the interior of the furnace body 1 through one of the second through holes 206, while humid air inside the furnace body 1 can be discharged through the other second through hole 206. The two second through holes 206 are symmetrically distributed about the middle of the first through hole 205.
[0026] As a technical optimization of this utility model, two air guide pipes 213 are fixedly connected to the top side of the valve block 204. The air guide pipes 213 are generally L-shaped, so the discharged gas can be guided through the air guide pipes 213 to prevent the discharged moisture from being drawn back into the interior of the furnace body 1.
[0027] As a technical optimization of this utility model, the drive structure 3 includes a support plate 301 and a first motor 302. The support plate 301 is fixedly connected to the connecting sleeve 203, and the first motor 302 is mounted on the support plate 301. A first synchronous pulley 303 is fixedly connected to the output shaft of the first motor 302, and a second synchronous pulley 305 is fixedly connected to the valve block 204. The first synchronous pulley 303 and the second synchronous pulley 305 are wound with the same synchronous belt 304, so the valve block 204 can be automatically driven to rotate, thereby realizing the automatic switching between hot air circulation mode and dehumidification mode.
[0028] As a technical optimization of this utility model, the placement structure 4 includes a main shaft 401 and a tray 402. The main shaft 401 is rotatably connected to the furnace body 1, and multiple trays 402 are fixedly connected to the main shaft 401. The trays 402 can support the placement trays 403. Two placement trays 403 are placed on the top side of the tray 402. Materials can be placed on the placement trays 403, and the placement trays 403 can be removed from the trays 402 during the process of picking up and putting down materials, thereby facilitating the picking up and putting down of materials.
[0029] As a technical optimization of this utility model, a second motor 404 is installed on the furnace body 1. The output shaft of the second motor 404 is fixedly connected to the top end of the main shaft 401. Therefore, during the drying process, multiple trays 403 can be rotated under the drive of the second motor 404, thereby improving the uniformity of drying.
[0030] As a technical optimization of this utility model, the storage tray 403 has an outwardly extending protrusion near the top, which makes it easy to grasp the storage tray 403 and thus facilitates the movement of the storage tray 403. The multiple trays 402 are linearly and equidistantly distributed, which makes full use of the space inside the furnace body 1.
[0031] As a technical optimization of this utility model, a sealing door 6 is installed on the furnace body 1, so that the furnace body 1 can be sealed during the drying process. Four support legs 7 are fixedly connected to the bottom of the furnace body 1, so that the furnace body 1 can be stably supported by the four support legs 7.
[0032] In use, this invention allows the materials to be dried to be evenly placed on the tray 403, and then the tray 403 is placed on the pallet 402. Each pallet 402 can hold two trays 403. After the materials are placed, the sealing door 6 is closed. Then, the second motor 404 is started. The rotation of the second motor 404 drives the main shaft 401 to rotate, which in turn causes multiple pallets 402 to rotate synchronously. Therefore, during the drying process, materials in different positions can fully contact the hot air. This effectively ensures the uniformity of drying. During drying, the blower 210 is activated, and under the action of the blower 210, gas is blown out from multiple air outlets 212. During the flow of gas, it is heated by multiple heating wires 209. The hot air blown on the surface of the material will achieve the drying and volatilization of the material. Under the action of the blower 210, the hot air with a certain amount of residual heat will enter the interior of the air inlet pipe 201 through multiple air inlet holes 202, then enter the interior of the valve block 204, and flow into the interior of the square tube 207 through the first through hole 205, and then out of the interior of the square tube 207. The air enters the interior of the exhaust pipe 211 and is finally blown out from multiple exhaust holes 212, thus realizing the recycling of hot air, effectively saving energy consumption and improving the environmental friendliness of use. As the drying time increases, the humidity of the air inside the furnace body 1 will increase. When the humidity sensor 5 detects that the air is relatively humid, the output shaft of the first motor 302 will rotate, driving the first synchronous pulley 303 to rotate. The rotation of the first synchronous pulley 303 will drive the second synchronous pulley 305 to rotate through the synchronous belt 304. The rotation of the second synchronous pulley 305 will drive the valve block 204 to rotate. When the valve block 20... 4. When the first motor 302 is rotated 90 degrees, the output shaft stops rotating. At this time, one of the second through holes 206 is connected to the square tube 207, and the other second through hole 206 is connected to the air inlet pipe 201. Therefore, the external air will enter the valve block 204 from the inside of one of the second through holes 206 and eventually enter the furnace body 1. The humid air inside the furnace body 1 will eventually be discharged from the other second through hole 206, thus avoiding the situation where the drying and volatilization effect is poor due to high air humidity, and effectively ensuring the drying and volatilization effect of the material.
