Abstract

This invention relates to the field of drying equipment technology and proposes an energy-saving drying oven, including a box body. A dispersing mechanism is installed inside the box body, and the dispersing mechanism includes a sealing door rotatably installed inside the box body. A rotating shaft is rotatably installed inside the sealing door. The box body has a drying chamber, and at least one layer of trays is arranged vertically within the drying chamber. Through the dispersing mechanism, ventilation mechanism, and other structures, when the sealing door is opened, the material trays converge towards the sealing door, facilitating the retrieval of finished materials and the placement of processed materials. When the sealing door is closed, the material trays disperse, and then the motor in the ventilation mechanism is activated.

This achieves uniform baking of materials and allows for constant monitoring of the materials.

Description

Technical Field

[0001] This invention relates to the field of drying equipment technology, specifically to an energy-saving drying oven. Background Technology

[0002] Currently, drying ovens are a common type of drying equipment. They use electric heating or steam heating to dry items in a closed chamber. Drying ovens come in a variety of models and have various uses, and can be applied to different industries and scenarios, such as industrial production, laboratories, and food processing. In industrial production, drying ovens are often used to dry various raw materials, intermediates, and finished products.

[0003] The prior art, with authorization announcement number CN211526951U, is entitled "An Oven". The oven includes an oven body and a motor located on top of the oven body. The output end of the motor is fixedly connected to the top of a rotating shaft, and the bottom end of the rotating shaft is connected to a rotating seat. The rotating seat is installed at the bottom of the oven body, and an inner chamber is installed in the middle of the rotating shaft. The inner chamber is fixedly connected to the rotating shaft. This oven rotates the material inside the oven by rotating the motor, making the material inside the oven heated more evenly. By setting the inner chamber connected to the rotating shaft, the items to be dried can rotate with the inner chamber, thereby achieving a uniform heating effect and ensuring the quality of the dried items.

[0004] However, when using this patent, heat dissipates from the top, which can easily lead to a situation where the heat is high in the middle and low at the periphery, resulting in uneven baking of the material. Furthermore, during baking, the material can only be observed through the external glass window, making it impossible to observe the degree of baking in detail. When detailed observation is needed, the oven needs to be opened, at which point the temperature difference between the inside and outside of the oven is large, which can easily affect the baking of the material and increase the baking power.

[0016] The working principle and beneficial effects of this invention are as follows:

[0017] 1. The present invention, through the setting of a dispersion mechanism, a ventilation mechanism and other structures, allows the material placement tray to gather towards the sealing door when the sealing door is opened, which facilitates the retrieval of finished materials and the placement of processed materials. When the sealing door is closed, the material placement tray disperses, and then the motor in the ventilation mechanism is turned on. While circulating inside the oven, the air outlet blades swing evenly to deliver air, making the heating of the oven more uniform.

[0018] 2. This invention, through the setting of a sample observation mechanism, a stepper motor, and other structures, allows a sample to be placed on a sample placement tray in the sample observation mechanism before the oven starts operating. Then, the sample is sent into the oven for baking by turning on the stepper motor. During the process, the sample placement tray can be sent into the sealed door by turning on the stepper motor.

[0019] 3. This invention, through the setting of preheating and ventilation mechanism, exhaust gas detector and other structures, allows the exhaust gas detector to detect the circulating gas inside the oven during operation. When the harmful substances in the circulating gas reach a certain level, the rotary handle and linkage handle are turned to open the air exchange valve, air inlet valve and air outlet valve. The gas inside the oven is replaced by an external blower to prevent the harmful gases inside the oven from adversely affecting the materials. At the same time, the harmful gases are centrally treated, making the operation of the oven more environmentally friendly. Attached Figure Description

[0037] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0038] Example 1: As Figure 1-15As shown, this embodiment proposes an energy-saving drying oven, including a box body 1. A dispersion mechanism 2 is installed inside the box body 1. The dispersion mechanism 2 includes a sealing door 21, which is rotatably installed inside the box body 1. A rotating shaft 22 is rotatably installed inside the sealing door 21. The box body 1 is provided with a drying chamber. At least one layer of trays is arranged in the drying chamber along the vertical direction. Each tray group includes several material placement trays 24 that are slidably connected to the box body 1 and arranged in parallel along the horizontal direction. Multiple ventilation trays 242 are arranged in parallel along the longitudinal direction on the material placement trays 24. In each tray group, the innermost material placement tray 24 in the horizontal direction is the mother material placement tray, and the remaining material placement trays 24 are the daughter material placement trays. An internally threaded block 243 is fixedly connected to one longitudinal side of the mother material placement tray. Sliding positioning rods 241 are fixedly connected to both longitudinal sides of the material placement tray 24. The sliding positioning rods 241 between adjacent material placement trays 24 are slidably engaged. A follower shaft 23, corresponding to the tray assembly, is rotatably installed inside the housing 1. The follower shaft 23 is connected to the rotating shaft 22 so that it rotates when the rotating shaft 22 rotates. A transmission screw 232 is fixedly connected to one side of the follower shaft 23. An internally threaded positioning block 244, corresponding to the child material placement tray, is movably sleeved on the transmission screw 232. Distributive positioning rods 25, corresponding to the tray assembly, are fixedly connected to the housing 1. Each tray assembly... The other longitudinal side of the material placement tray 24 is slidably fitted onto the corresponding dispersion positioning rod 25. The inner hole positioning block 244 is fixedly connected to one longitudinal side of the sub-material placement tray. A ventilation mechanism 3 is installed inside the box 1. The ventilation mechanism 3 includes a motor 31, which is installed on the top of the box 1. The output end of the motor 31 is connected to a coaxially arranged drive shaft 311 through a coupling. An inlet fan blade 312 is fixedly connected to the bottom of the drive shaft 311. A follower shaft 32, a driven shaft 33, an outlet shaft 36, and a rotating shaft 34 are rotatably mounted on the box 1. An outlet fan blade 361 is fixedly connected to one end of the outlet shaft 36. The drive shaft 311 and the follower shaft 32 are connected to the drive shaft 33. 2. Transmission connection: the follower shaft 32 is driven by the driven shaft 33, the driven shaft 33 is driven by the rotating shaft 34, the follower shaft 32 is driven by the air outlet shaft 36, the end of the rotating shaft 34 is fixedly connected to the turntable 342, the non-central part of the turntable 342 is movably hinged to the crank rod 343, the inside of the housing 1 is fixedly connected to the fixed square plate 35, the inside of the fixed square plate 35 is rotatably installed with multiple equidistantly distributed air outlet shafts 352, the end of the air outlet shaft 352 is eccentrically hinged to the limit rod 351, the limit rods 351 at the same end of the air outlet shaft 352 are movably hinged to the connecting block 353, and one end of the crank rod 343 is hinged to the corresponding connecting block 353.

[0039] In this embodiment, among the adjacent sliding positioning rods 241, one sliding positioning rod 241 is provided with a retaining shaft, and the end of the retaining shaft is provided with a retaining protrusion. The other sliding positioning rod 241 is provided with a retaining hole, and the end of the retaining hole near the retaining shaft is provided with a retaining ring. The retaining shaft is slidably disposed in the retaining hole, and the retaining shaft has a displacement stroke in the retaining hole. The retaining protrusion and the retaining ring are adapted to abut against each other.

[0040] like Figure 6-8 As shown, a drive sector gear 221 corresponding to the corresponding follower shaft 23 is fixedly sleeved on the rotating shaft 22, and a follower sector gear 231 is fixedly sleeved on the follower shaft 23. The drive sector gear 221 meshes with the corresponding follower sector gear 231.

[0041] like Figure 6-9 Both the active rotating shaft 311 and the follower rotating shaft 32 are fixedly fitted with transmission wheels on their outer circumferential surfaces, and a transmission belt 313 is installed on the outer circumferential surfaces of the two transmission wheels. Both the follower rotating shaft 32 and the air outlet rotating shaft 36 are fixedly fitted with conveyor wheels, and a conveyor belt 322 is installed on the outer circumferential surfaces of the two conveyor wheels.

[0042] like Figure 6-10 A meshing gear 321 is fixedly sleeved on the outer circumferential surface of the follower shaft 32, and a rotating gear 331 is fixedly sleeved on the outer circumferential surface of the driven shaft 33. The meshing gear 321 meshes with the rotating gear 331.

[0043] like Figure 6-10 A drive bevel gear 332 is fixedly sleeved on the outer circumferential surface of the driven shaft 33, and a driven bevel gear 341 is fixedly sleeved on the outer circumferential surface of the rotating shaft 34. The drive bevel gear 332 meshes with the driven bevel gear 341.

[0044] The specific implementation principle of this embodiment is as follows: When the sealing door 21 is opened, the sealing door 21 rotates, driving the rotating shaft 22 inside the sealing door 21 to rotate. The driving sector gear 221 on the rotating shaft 22 rotates with the rotating shaft 22. The driving sector gear 221 meshes with the follower sector gear 231. While the driving sector gear 221 rotates, it drives the follower sector gear 231 to rotate. One side of the follower sector gear 231 is connected to the follower shaft 23, and one side of the follower shaft 23 has a transmission screw 232. When the follower sector gear 231 rotates, it drives the transmission screw 232 to rotate. The transmission screw 232 is also threaded into the interior of the internal thread block 243. The internal thread block 243 is fixedly connected to the material placement tray 24 at the innermost part of the oven. When the sealing door 21 is opened, the transmission screw 232 rotates forward, thereby driving the material placement tray 24 at the innermost part of the oven to move towards the sealing door 21. Each material placement tray 24 has cavities on both sides, allowing the sliding positioning rod to move. The sliding cavity and sliding positioning rod 241 allow the innermost material placement tray 24 of the oven to slide while simultaneously moving other material placement trays 24. A ventilation disc 242 is provided on the placement tray 24 to facilitate air circulation during drying. When the innermost material placement tray 24 moves towards the sealing door 21, it moves other material placement trays 24 towards the sealing door 21. Conversely, when the sealing door 21 closes, the rotating shaft 22 rotates in the opposite direction, causing the transmission screw 232 to rotate in the opposite direction, thus moving the innermost material placement tray 24 further into the oven. As the innermost material tray 24 moves into the oven, it moves the sliding positioning rod 241. The remaining material placement trays 24 in the same layer are pulled together by the engagement of the locking protrusion and locking ring on the sliding positioning rod 241, thus completely dispersing the remaining material trays 24 as the innermost material tray 24 slides, resulting in more uniform baking of the material.

[0045] Secondly, after the materials are dispersed on the material placement tray 24, the motor 31 at the top of the chamber 1 is turned on. The motor 31 rotates, simultaneously driving the drive shaft 311 to rotate. The bottom of the drive shaft 311 is connected to an inlet fan blade 312. The rotation of the drive shaft 311 drives the inlet fan blade 312 to draw in air. The drive shaft 311 and the follower shaft 32 are connected by a transmission belt 313. The rotation of the drive shaft 311 drives the follower shaft 32 to rotate. The follower shaft 23 and the outlet shaft 36 are connected by a transmission belt 313. The rotation of the follower shaft 32 drives the outlet shaft 36 to rotate. The rotation of the outlet shaft 36 drives the outlet fan blade 361 to rotate. The interaction between the inlet fan blade 312 and the outlet fan blade 361 circulates the gas inside the oven. A meshing gear 321 on the follower shaft 32 meshes with a rotating gear 331 on the driven shaft 33. The rotation of the follower shaft 32 drives the air intake fan blade 361 to rotate. The driven shaft 33 rotates, and the driven shaft 33 has a driving bevel gear 332 meshing with the driven bevel gear 341 on the rotating shaft 34. The rotation of the driven shaft 33 simultaneously drives the rotating shaft 34 to rotate, which in turn drives the turntables 342 on both sides of the rotating shaft 34 to rotate. The rotation of the turntables 342 drives the crankshaft 343 to rotate. One end of the crankshaft 343 is connected to the connecting block 353. When the turntables 342 rotate, they drive the crankshaft 343 to rotate. When the crank lever 343 is rotated, one end of the crank lever 343 is movably hinged to the connecting block 353. The connecting block 353 is limited by the limiting block on the fixed plate 35, thereby driving the connecting block 353 to slide back and forth. The connecting block 353 and the air outlet shaft 352 are movably hinged to the limiting lever 351, thereby driving the air outlet shaft 352 to rotate back and forth, causing the air outlet blades 354 to swing, and evenly fanning the air of the inlet fan blades 312, making the air blowing of the material more uniform.

[0046] Example 2: Figure 1-14 Based on Embodiment 1, this embodiment adds the following structure: a sample observation mechanism 4 is installed inside the sealing door 21. The sample observation mechanism 4 includes a sample placement tray 42 slidably connected to the sealing door 21. The sealing door 21 is provided with a pick-up and put-down channel corresponding to the sample placement tray 42. The outer wall of the sealing door 21 is provided with an outer opening that communicates with the pick-up and put-down channel. The inner wall of the sealing door 21 is provided with an inner opening that communicates with the pick-up and put-down channel. The sample observation mechanism 4 also includes a sample placement tray sliding component connected to the sample placement tray 42 to facilitate the sliding of the sample placement tray 42. During the sliding process, the sample placement tray 42 is suitable for entering the pick-up and put-down channel or the oven interior. The sealing door 21 is provided with an opening and closing door component suitable for simultaneously opening the outer opening and closing the inner opening or simultaneously opening the inner opening and closing the outer opening.

[0047] Specifically, if Figure 14As shown, the door opening and closing component includes an outer sliding door 45 adapted to open or close the outer opening, an inner sliding door 46 adapted to close or open the inner opening, and a linkage component. The linkage component is connected to the outer sliding door 45 and the inner sliding door 46 respectively, and the linkage component is adapted to drive the outer sliding door 45 and the inner sliding door 46 to move towards each other or away from each other.

[0048] Specifically, if Figure 14 As shown, the linkage assembly includes a transmission gear 44, an outer sliding rack 452, and an inner sliding rack 461. The transmission gear 44 is rotatably connected to the sealing door 21. The outer sliding rack 452 is fixedly connected to the outer sliding door 45, and the inner sliding rack 461 is fixedly connected to the inner sliding door 46. The transmission gear 44 is meshed with the outer sliding rack 452 and the inner sliding rack 461 respectively.

[0049] Specifically, if Figure 14 As shown, the sliding component of the sample placement tray includes a stepper motor 41. The output end of the stepper motor 41 is connected to a coaxially arranged rotating rod 411 through a coupling. A transmission rack 422 is fixedly connected to the sample placement tray 42. A transmission gear 412 that meshes with the corresponding transmission rack 422 is fixedly sleeved on the rotating rod 411.

[0050] Specifically, if Figure 14 As shown, the transmission gear 44 is rotatably connected to the sealing door 21 via the transmission shaft 43.

[0051] Specifically, if Figure 14 As shown, a sliding handle 451 is fixedly connected to one side of the outer sliding door 45.

[0052] Specifically, a sliding positioning block 421 that slides on the sealing door 21 is fixedly connected to one side of the sample placement tray 42, and a transmission rack 422 can be set on the other side of the sample placement tray 42.

[0053] In this embodiment, there are four sample placement trays 42 distributed at equal intervals from top to bottom. Correspondingly, there are also four pick-up and drop channels, four opening and closing door components, four transmission racks 422 and four transmission gears 412. However, this is not a limitation and can be specifically set according to requirements.

[0054] In this embodiment, after the sealing door 21 is closed, the sliding handle 451 can be pulled to open the outer sliding door 45. As the outer sliding door 45 opens, it drives the outer sliding rack 452 to slide, which in turn drives the transmission gear 44 to rotate. Simultaneously, the transmission gear 44 rotates, driving the inner sliding rack 461 to slide. The inner sliding rack 461 then closes the inner sliding door 46, isolating the interior of the oven. The sample material is then placed in the sample placement tray 42, and the outer sliding door 45 is closed. Simultaneously, the inner sliding door 46 opens, and the stepper motor 41 is activated. The stepper motor 41 rotates, driving the rotating rod 411 to rotate. The rotating rod 411 then... The drive gear 412 rotates, and at the same time, the drive rack 422 slides. The sliding of the drive rack 422 causes the sample placement tray 42 to slide, and the sample placement tray 42 extends into the oven to bake the sample. During the baking process, the stepper motor 41 can be reversed to retract the sample placement tray 42. Then, the sliding handle 451 is pulled to open the outer sliding door 45. At the same time as the outer sliding door 45 is opened, the inner sliding door 46 is closed. At this time, the sample can be taken out for observation to understand the baking status of the internal material. The sealing door 21 is equipped with four outer sliding doors 45 and four inner sliding doors 46, which can observe the baking status at different positions and thus judge the situation inside the oven.

An air exchange ball valve 523 is rotatably installed inside the 52. An air exchange ball valve 523 is fixedly connected to one side of the air exchange ball valve 523. A rotating handle 522 is fixedly connected to one end of the air exchange ball valve 521. An air inlet dispersion pipe 512 is installed on one side of the two preheating air exchange boxes 51. An air inlet pipe 513 is installed on one side of the air inlet dispersion pipe 512. An exhaust gas box 53 is fixedly connected to the bottom of the box 1. An exhaust gas concentration pipe 531 is installed on one side of the exhaust gas box 53. An exhaust gas concentration pipe 532 is installed on one side of the exhaust gas concentration pipe 531. A linkage shaft 54 ​​is rotatably installed inside the air inlet pipe 513 and the exhaust pipe 532. An air inlet ball valve 541 and an exhaust ball valve 542 are fixedly sleeved on the outer circumference of the linkage shaft 54. A linkage handle 543 is fixedly connected to one end of the linkage shaft 54.

[0056] The exhaust gas detector 501 can specifically use the following model of exhaust gas detector: model: GASTiger2000 pump-suction composite gas detector. Its principle is: the gas to be detected is drawn in by a sampling pump, and the gas content is analyzed by the gas detector calibration hood. The oxygen is detected by the instrument's sensor, and then the circuit amplifies and converts it into the corresponding value displayed on the screen.

[0057] In this embodiment, a fiberglass insulation layer 13 is provided inside the oven body 1. The fiberglass insulation layer 13 can increase the heat insulation performance of the oven. An electrostatic powder coating layer 14 is provided on the outside of the oven body 1, which can effectively protect the outer layer of the oven. Eight far-infrared heaters 12 are provided inside the oven body 1 at equal intervals. A preheating ventilation box 51 is simultaneously provided on one side of the corresponding far-infrared heater 12. The far-infrared heaters 12 preheat the gas in the preheating ventilation pipe 52 while heating the inside of the oven. While the oven is heating and baking, the gas in the preheating ventilation box 51 can be preheated to prevent the gas from entering at room temperature during ventilation, thereby increasing the power consumption of the external infrared heater and saving energy.

[0058] Furthermore, during the circulation process of the gas inside the oven, it passes through the exhaust gas detector 501, which is electrically connected to the controller 11. The controller 11 can monitor the circulating gas situation inside the oven in real time. When the level of harmful substances in the circulating gas is too high, the rotary handle 522 and the linkage handle 543 can be opened. The rotation of the rotary handle 522 drives the air exchange valve 523 to rotate, and when the air exchange valve 523 rotates, the air exchange pipe 52 opens to allow ventilation. The rotation of the linkage handle 543 drives the linkage shaft 54 ​​to rotate, and the rotation of the linkage shaft 54 ​​drives the inlet air ball valve 541 and the outlet air ball valve 542 to rotate. The rotation of the balloon valve 542 opens the air inlet pipe 513 and the air outlet pipe 532. At this time, the external fan is turned on, and the gas is sent from the air inlet pipe 513 into the air inlet dispersion pipe 512, and then from the air inlet dispersion pipe 512 into the interior of the two preheating air exchange boxes 51. The preheated gas is sent into the air exchange central pipe 511, and then from the air exchange central pipe 511 into the interior of the oven. At this time, the exhaust gas is discharged from the exhaust gas box 53 at the bottom of the oven, passes through the exhaust central pipe 531 to the exhaust pipe 532, and the exhaust pipe 532 sends the exhaust gas to the exhaust gas recovery point for recycling, so that the gas in the oven is circulated, saving energy and protecting the environment.

[0059] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
