Description

Technical Field

[0001] This utility model relates to the field of oven technology, specifically a high-temperature oven with a three-dimensional hot air circulation function. Background Technology

[0002] An electric drying oven is a heat processing device that uses electrical energy to heat air or infrared radiation to dry, cure, or heat-treat materials. It uses resistance wire, quartz tube, or hot air circulation system as the heat source, and the temperature range is typically from room temperature to 300°C.

[0003] In the prior art, patent announcement number CN222635014U discloses a hot air circulating electric heating oven, including a box body and an air outlet hood. A placement plate is fixedly connected to the outside of the air outlet hood, and a frame is placed on the upper end of the placement plate. An activated carbon adsorption layer is provided on the frame. A pair of fixing plates are fixedly connected to both sides of the frame. A connecting plate is rotatably connected between the two fixing plates through a rotating shaft. A through hole is opened on the connecting plate. A sealing gasket is provided on the air outlet hood, and a pair of threaded rods are fixedly connected to the placement plate. Nuts are threaded onto the threaded rods.

[0004] The aforementioned device, through the combined use of an exhaust hood, air duct, air inlet hood, and fan, allows high-temperature gas to circulate between the top and bottom of the chamber. However, some ovens have multiple shelves, and the high-temperature gas loses some heat with each shelf it passes through, resulting in uneven drying between layers. Furthermore, material accumulation on the shelf surface also affects the drying effect. Summary of the Invention

[0005] The purpose of this invention is to provide a high-temperature oven with a three-dimensional hot air circulation function to solve the problems in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-temperature oven with a three-dimensional hot air circulation function, comprising an oven body, with shelves spaced apart inside the oven body, a door rotatably mounted on the oven body, and a circulation mechanism installed on the oven body. The circulation mechanism includes a volute fixedly mounted on the upper end of the oven body, an air outlet pipe fixedly mounted on one side of the volute, an air inlet pipe fixedly mounted on the other side of the volute, a heater fixedly mounted on the air outlet pipe, and air vents on both the air inlet and outlet pipes facing the shelves. A material turning mechanism is provided above the shelves.

[0007] Preferably, the circulation mechanism further includes a motor fixedly mounted on the volute, the output end of the motor being fixedly mounted with a movable shaft, and a fan blade being fixedly mounted on the movable shaft.

[0008] Preferably, a bearing is installed on the volute, and the movable shaft is rotatably installed inside the volute via the bearing.

[0009] Preferably, the fan blade is rotatably mounted inside the volute via a movable shaft, one end of the air outlet pipe is connected to the air outlet of the volute, and the other end of the air outlet pipe is connected to one side of the oven body, one end of the air inlet pipe is connected to the air inlet of the volute, and the other end of the air inlet pipe is connected to the other side of the oven body.

[0010] Preferably, the material turning mechanism includes a positioning slide groove fixedly installed inside the oven body, a reciprocating lead screw rotatably installed in the positioning slide groove, a lead screw slider slidably installed in the positioning slide groove, and the lead screw slider threaded onto the reciprocating lead screw. A drive shaft is installed at one end of the lead screw slider, a reducer is installed on the drive shaft, a connecting seat is fixedly installed at the bottom of the lead screw slider, a turning frame is fixedly installed on the connecting seat, and helical gears are fixedly installed on the movable shaft, the drive shaft, and the reciprocating lead screw, with the helical gears meshing together in pairs.

[0011] Preferably, a bearing is installed on the positioning slide groove, and the drive shaft and the reciprocating lead screw are rotatably mounted in the positioning slide groove through the bearing.

[0012] Preferably, the lead screw slider is movably mounted inside the oven body via a positioning groove, and the flipping frame is movably mounted above the shelf via the lead screw slider.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. In this application, after the motor starts, its driven shaft rotates, which in turn drives the fan blades to rotate. The rotation of the fan blades acts on the gas, transporting it to the heater for heating. The heated gas is then transported to each shelf through the outlet duct, and after contacting the shelf, the gas is recirculated through the inlet duct, achieving circulation of high-temperature gas between the shelves. This process ensures uniform heating of the materials on the shelves.

[0014] 2. In this application, the rotational motion of the movable shaft is transmitted through a transmission shaft and reduced in speed by a reducer, causing the reciprocating lead screw to rotate at a slower speed. This rotational motion causes the lead screw slider to slide back and forth within the positioning groove, thereby driving the flipping frame to perform reciprocating motion above the shelf. This process achieves the flipping of materials on the shelf, ensuring that the materials are heated evenly. Attached Figure Description

[0017] 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.

[0018] like Figure 1 and Figure 2 As shown, this utility model provides a technical solution for a high-temperature drying oven with a three-dimensional hot air circulation function, including an oven body 1, with shelves 2 installed at intervals inside the oven body 1, a door 3 rotatably installed on the oven body 1, a circulation mechanism 4 installed on the oven body 1, and a material turning mechanism 5 provided above the shelves 2. Through the cooperation of the circulation mechanism 4 and the material turning mechanism 5, the material can be heated evenly, thus improving the drying quality.

[0019] like Figure 2 and Figure 3 As shown, the circulation mechanism 4 includes a volute 401 fixedly installed on the upper end of the oven body 1. An air outlet pipe 404 is fixedly installed on one side of the volute 401, and an air inlet pipe 405 is fixedly installed on the other side of the volute 401. A heater 402 is fixedly installed on the air outlet pipe 404. The air vents on the air inlet pipe 405 and the air outlet pipe 404 both face the shelf 2. The circulation mechanism 4 also includes a motor 403 fixedly installed on the volute 401. A movable shaft 406 is fixedly installed at the output end of the motor 403. A fan blade 407 is fixedly installed on the movable shaft 406. A bearing is installed on the volute 401, and the movable shaft 406 is rotatably installed inside the volute 401 through the bearing.

[0020] Specifically, when motor 403 is started, it begins to operate and drives movable shaft 406 to rotate. During the rotation of movable shaft 406, fan blades 407 also rotate. The rotation of fan blades 407 sends gas into heater 402 for heating. The heated gas is then transported to the shelves 2 on each level through exhaust duct 404. After being blown onto the shelves 2, the heated gas is circulated back into heater 402 through intake duct 405. Through this circulation, the gas continuously circulates between the shelves 2. This circulation ensures that the materials on the shelves 2 receive heat evenly, achieving a uniform heating effect.

[0021] like Figure 2 and Figure 4 As shown, the material turning mechanism 5 includes a positioning slide groove 503 fixedly installed inside the oven body 1. A reciprocating lead screw 506 is rotatably installed inside the positioning slide groove 503. A lead screw slider 505 is slidably installed inside the positioning slide groove 503, and the lead screw slider 505 is threaded onto the reciprocating lead screw 506. A drive shaft 502 is installed at one end of the lead screw slider 505. A reducer 501 is installed on the drive shaft 502. A connecting seat 507 is fixedly installed at the bottom of the lead screw slider 505. A turning frame 504 is fixedly installed on the connecting seat 507. Helical gears 508 are fixedly installed on the movable shaft 406, the drive shaft 502, and the reciprocating lead screw 506, and the helical gears 508 mesh together in pairs. A bearing is installed on the positioning slide groove 503. The drive shaft 502 and the reciprocating lead screw 506 are rotatably installed in the positioning slide groove 503 through the bearing.

[0022] Specifically, when the movable shaft 406 starts to rotate, it drives the transmission shaft 502 to rotate accordingly. During the rotation of the transmission shaft 502, the speed is reduced by the speed reducer 501. After the speed reduction, the transmission shaft 502 continues to rotate, which in turn drives the reciprocating screw 506 to rotate at a slow and stable speed. As the reciprocating screw 506 rotates slowly, it interacts with the screw slider 505, causing the screw slider 505 to slide back and forth within the positioning groove 503. This reciprocating sliding motion is further transmitted to the flipping frame 504, causing it to reciprocate above the shelf 2. This reciprocating motion of the flipping frame 504 ultimately achieves the flipping of the material on the shelf 2, ensuring that the material receives uniform heat distribution during the heating process, thereby achieving a uniform heating effect.

[0023] Working principle: When in use, the motor 403 can be started. After the motor 403 is started, it will drive the movable shaft 406 to rotate. After the movable shaft 406 rotates, it will drive the fan blade 407 to rotate. After the fan blade 407 rotates, it will send the gas into the heater 402 for heating. The heated gas will be blown to each shelf 2 through the air outlet 404. The gas blown to each shelf 2 will then circulate back into the shelf 2 through the air inlet 405, realizing the circulation of gas between each shelf 2, so that the material on the shelf 2 is heated evenly. Furthermore, when the movable shaft 406 rotates, it will drive the transmission shaft 502 to rotate. After being reduced in speed by the reducer 501, the transmission shaft 502 will drive the reciprocating lead screw 506 to rotate slowly. When the reciprocating lead screw 506 rotates slowly, it will drive the lead screw slider 505 to slide back and forth in the positioning groove 503. When the lead screw slider 505 slides back and forth in the positioning groove 503, it will drive the flipping frame 504 to move back and forth above the shelf 2, thereby flipping the material on the shelf 2 and further making the material evenly heated.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
