Referring to fig. 1-11, a solvent recovery vacuum drying oven with an intelligent material taking system comprises a vacuum drying oven body 1 with a heating assembly arranged therein and a vacuum pump 2, wherein the vacuum drying oven body 1 and the vacuum pump 2 are connected through a condensing pipe 3, and a solvent recovery barrel 4 is arranged below the vacuum pump 2; a switch door 11 is arranged on the side wall of one side of the box body 1, and an air suction opening 12 is arranged on the side wall of one side corresponding to the switch door 11; the suction opening 12 is connected with the vacuum pump 2 through the condensation pipe 3.

It should be noted that the placed materials need to be of the same original weight, i.e. the weight of each material in the dry state. Because the material is still on the supporting plate 51, the drying efficiency of the material is low, the rotating mechanism is arranged in the drying device, and the rotating mechanism drives the material to rotate on the supporting plate 51 during drying, so that the material is uniformly heated, and the drying efficiency of the material is improved. Because each material moisture content is different, required drying time is different again, and this can make whole drying time can regard as the drying time of the material that finishes drying behind the left as the standard, leads to whole drying inefficiency. Therefore, the rotating mechanism can move the heavier materials to be dried to the air suction opening 12 to stay according to the weight difference of the materials to be dried; because the original weight of the materials placed in the vacuum drying box is the same, the weight of the materials is different due to different humidity, and the heavier materials to be dried are moved to the air suction opening 12 to stay, namely the materials with higher humidity stay at the air suction opening 12; the air suction opening 12 is connected with the vacuum pump 2, the material at the air suction opening 12 has larger air flow at the position, so that the drying speed of the material with larger humidity at the position is higher than that of other positions in the box. The invention can not only ensure that each material to be dried is heated uniformly, but also increase the drying efficiency; can also be according to each humidity difference of treating the dry material, the higher material of treating of humidity is removed to the inlet scoop 12 department of vacuum drying cabinet and is stopped, increases the drying rate of the higher material of treating of humidity for the drying efficiency of whole material is balanced, improves holistic drying efficiency.
As a further aspect of the present invention, the rotating mechanism includes a first rotating shaft 52 rotatably installed at the center of the supporting plate 51, a first rotating disc 53 is provided at the upper end of the first rotating shaft 52, and the first rotating shaft 52 is ball-jointed with the first rotating disc 53; connecting plates 54 are arranged at intervals along the circumferential direction of the first rotating disc 53, and bearing platforms 55 for placing materials to be dried are arranged on the connecting plates 54; the first rotating shaft 52 is externally connected with a driving power supply, a driving gear 56 is fixedly mounted on the first rotating shaft 52, planetary gears 57 are circumferentially arranged at intervals on the driving gear 56, and an inner gear ring 58 is arranged on the outer side of the planetary gears 57; the driving gear 56 is externally meshed with the planet gears, and the planet gears 57 are internally meshed with the inner gear ring 58; the planetary gear 57 is connected with the bearing platform 55 through a second rotating shaft 59, a groove 60 is formed in the bottom of the bearing platform 55, a U-shaped groove 61 is formed in the connecting plate 54, the second rotating shaft 59 penetrates through the U-shaped groove 61 and is vertically and slidably mounted in the groove 60, and a first compression spring 62 is arranged between the bottom end of the bearing platform 55 and the connecting plate 54; the annular groove 63 is formed in the inner gear ring 58, and the second rotating shaft 59 is connected with the annular groove 63 in a sliding mode;
as a further aspect of the present invention, a switching assembly is provided on the end of the supporting plate 51 near the air suction opening 12, and the switching assembly switches between limiting the rotation of the first rotating disk 53 and limiting the rotation of the inner gear ring 58.
The present invention provides an embodiment of a turning gear that meets the above needs. As shown in fig. 5 and 8, the invention is operated by placing the individual items to be dried on the individual support stands 55 in the circumferential direction of the first rotor disc 53. Because the original weight of each material is the same and the humidity is different, the weight of each material before drying is different, as shown in fig. 9, the bearing platform 55 moves downwards by the gravity of the material, and the bearing platform 55 compresses the first compression spring 62 and provides pressure for the connecting plate 54 at the position. Because the weight of each material before drying is different, the pressure experienced by each web 54 is also different. As shown in fig. 8, since the first rotary disk 53 provided with the connecting plate 54 is ball-jointed to the first rotary shaft 52 externally connected to the power supply, the first rotary disk 53 is deviated, and the originally horizontal first rotary disk 53 is inclined toward the end where the material is heavier. As shown in fig. 7 and 8, the switching member restricts rotation of ring gear 58 in the initial state; the first rotating shaft 52, which is externally connected to a power source, rotates to drive the driving gear 56 fixedly provided on the first rotating shaft 52 to rotate. The drive gear 56, the pinion 57, and the ring gear 58 constitute a planetary gear train, and with the ring gear 58 fixed, the drive gear 56 rotates to rotate while revolving the pinion 57. Since the planetary gear 57 is connected to the carrier 55 via the second rotating shaft 59, the carrier 55 rotates while revolving when the ring gear 58 is fixed. The rotation while the bearing table 55 drives the revolution of the material can make the material be heated uniformly in the box body 1, improving the drying efficiency. Since the first rotary disk 53 is inclined, as shown in fig. 9 and 11, the first rotary disk 53 is not affected in rotation of the second rotary shaft 59 when inclined due to the presence of the U-shaped groove 61 on the connecting rod, so that the entire first rotary disk 53 is rotated while being inclined. The switching assembly of the invention limits the rotation of the inner gear ring 58 when the first rotating disc 53 is balanced, and the driving gear 56 can drive the bearing platform 55 to rotate while revolving, so that each surface of the material can be heated uniformly, and the drying efficiency is accelerated; the switching component can restrict first rotation disc 53 at the incline direction department of first rotation disc 53 and rotate when first rotation disc 53 inclines, because the switching component is in inlet scoop 12 department, so the great material of humidity can restrict to stay in inlet scoop 12 department along with plummer 55, the flow of the air in inlet scoop 12 department is great, this drying rate that can make the great material of humidity in this department is higher than other places in the case, with the drying efficiency of this balanced whole material, make the drying time of each material unanimous, improve holistic drying efficiency. When switching over subassembly restriction first rotary disk 53 and rotate in addition, driving gear 56 rotates and can drive planetary gear 57 rotation, and plummer 55 drives the material rotation for each big face of material can be heated uniformly, receive the air-dry, improve drying efficiency.
As a further aspect of the present invention, the switching assembly includes a stopper plate 71 provided on the pallet 51; the end of each connecting plate 54 far away from the first rotating shaft 52 is connected with a ring 72 which is coaxial with the first rotating shaft 52; a vertical limiting groove 73 is formed in the circumferential direction of the circular ring 72, and the overall dimension of the limiting plate 71 is consistent with the dimension of the limiting groove 73; a limiting column 74 is vertically and slidably mounted on the upper end surface of the inner gear ring 58, and a second compression spring 75 is arranged between the limiting column 74 and the inner gear ring 58; the limit plate 71 limits the rotation of the first rotating disc 53 by being clamped into the limit groove 73, and the limit plate 71 limits the rotation of the inner gear ring 58 by blocking the limit column 74; the restraint posts 74 are located below the ring 72.
The present invention provides an embodiment of a switching assembly that meets the above-mentioned needs. As shown in fig. 6 and 11, the switching assembly of the present invention is fixedly disposed on the supporting plate 51, and when the first rotating disk 53 is balanced, the switching assembly limits the rotation of the inner gear ring 58, as shown in fig. 6: the stopper posts 74 of the ring gear 58 are stopped by the stopper plates 71 fixed to the pallet 51, so that the ring gear 58 is restricted from rotating. At this time, the driving gear 56 rotates when driving the planetary gear 57 to revolve, and because the second rotating shaft 59 is slidably installed in the U-shaped groove 61, the second rotating shaft 59 drives the first rotating disc 53 to rotate, so that the material rotates while revolving on the bearing table 55, and is uniformly heated, thereby improving the drying efficiency. When the weight of the materials is not uniform, the first rotary disk 53 rotates obliquely, and the ring 72 provided on the outer circumference of the first rotary disk 53 is inclined. When the limiting groove 73 on the ring 72 rotates to the limiting plate 71, the limiting plate 71 slides into the limiting groove 73 on the ring 72 to block the ring 72, so as to limit the rotation of the first rotating disk 53. When the retainer plate 71 is engaged in the retainer groove 73, the ring 72 tilts to press the retainer post 74 to move downward to press the second compression spring 75, and the retainer post 74 moves over the retainer plate 71. This completes the switching from restricting the rotation of the ring gear 58 to restricting the rotation of the first rotary disk 53. When the weight of the material is reduced rapidly after the material is dried rapidly, the whole first rotating disc 53 is restored to balance again, the limiting plate 71 slides out of the limiting groove 73, the limiting column 74 moves to the limiting plate 71 again to be clamped, and the bearing table 55 starts to revolve stably again. The switching component can automatically switch between the rotation of the first rotating disc 53 and the rotation of the inner gear ring 58 according to the weight change of the materials on the bearing table 55, and can limit the rotation of the first rotating disc 53 when the humidity difference between the materials is large, so that the materials to be dried with high humidity move to the air suction opening 12 of the vacuum drying box to stay, the drying speed of the materials to be dried with high humidity is increased, the drying efficiency of the whole materials is balanced, and the whole drying efficiency is improved; when the humidity between the materials is approximately consistent, the inner gear ring 58 is limited to rotate, so that the materials rotate during revolution, the heating is uniform, and the drying efficiency is improved.
As a further scheme of the invention, the upper end of the limiting column 74 is provided with a wedge surface 76. As shown in fig. 6, the purpose of this arrangement is to be able to press the limit post 74 when the circular ring 72 rotates obliquely, so that the limit post 74 can cross the limit of the limit plate 71 to realize switching.
As a further scheme of the invention, a spoiler 77 for stirring the gas in the box body 1 is fixedly arranged at the upper end of the inner gear ring 58; the spoilers 77 are provided at intervals along the circumferential direction of the ring gear 58. As shown in fig. 5 and 6, when the switching unit restricts the rotation of the first rotary disk 53, the ring gear 58 starts to rotate by the driving gear 56. The purpose of this arrangement is to enable the air in the case 1 to be agitated by the spoiler 77 when the ring gear 58 rotates, so that the air flows to improve the drying efficiency.
As a further aspect of the present invention, a second rotating disc 81 is rotatably mounted on the supporting plate 51, the rotating mechanism is arranged on the second rotating disc 81, and the inner gear ring 58 is rotatably mounted on the second rotating disc 81; an outer gear ring 82 is fixedly arranged on the periphery of the second rotating disc 81; the supporting plate 51 is horizontally and slidably installed in the box body 1, a rack 83 is fixedly installed on the side wall of the box body 1 along the sliding direction of the supporting plate 51, and the rack 83 is meshed with the outer gear ring 82.
When the existing vacuum drying box judges the drying condition of the materials, the drying condition of each material needs to be observed one by one before the materials are taken, the labor intensity of workers is increased, the whole drying time is prolonged, and the material taking efficiency is low. As shown in fig. 1 and 4, the switching mechanism of the present embodiment is fixedly provided on the second rotating disk 81. The present invention pulls the support plate 51 outward after opening the opening and closing door 11. Set up outer ring gear 82 in second rolling disc 81 periphery and the fixed rack 83 that sets up on box 1 lateral wall meshing when pulling layer board 51, rack 83 drive second rolling disc 81 rotates, will be close to plummer 55 rotation to switch door 11 department of inlet scoop 12 department originally, the material on the plummer 55 of this department is the biggest material of humidity, make things convenient for the staff to observe dry situation and use this to judge holistic material dryness fraction as the foundation, avoid the staff to observe the dry situation of each material one by one, simplify the observation step before getting the material, improve and get material efficiency. The rack 86 is a single-side rack and is arranged on one side of the box body. The first rotary disk 53 rotates half a turn in this embodiment.
