Detailed Description

Specific examples of the present invention will be described in further detail below. It should be understood that the description herein of embodiments of the invention is not intended to limit the scope of the invention.

Fig. 1 to 6 are schematic structural views of a rotary steam drying system according to the present invention. The rotary steam drying system 100 comprises a base 10, a rotary drying mechanism 20 fixedly mounted on the base 10, a feeding mechanism 30 mounted on the base 10, a discharging mechanism 40 mounted on the base 10, and a control device 50 for controlling the working states of the rotary drying mechanism 20, the feeding mechanism 30 and the discharging mechanism 40. It is contemplated that the automatic loading and unloading rotary steam drying system 100 may further include other functional modules, such as switches, wires, bearings for facilitating rotation, etc., which are well known to those skilled in the art and will not be described in detail herein.

The base 10 may be a plate-shaped structure for arranging various functional modules, such as a feeding mechanism 30, a discharging mechanism 40, a rotary drying mechanism 20, and the like. The base 10 may be made of a metal material or a wood board, which is selected according to actual needs. The shape of the base 10 may be square, circular, or any other shape, and is selected according to actual requirements. In this embodiment, the base 10 is a square plate made of iron plate to facilitate welding of various fixing devices, such as screws and the like.

The rotary drying mechanism 20 includes a support base 21 disposed on the base 10, a dryer 22 mounted on the support base 21, a driving motor 23 disposed on the base 10, and a transmission device 24 connecting the driving motor 23 and the dryer 22. It is of course contemplated that rotary drying mechanism 20 may include other structural components, such as fasteners, etc.

The supporting base 21 mainly serves to support and support the dryer 22, since the dryer 22 needs to be rotated and must be disposed at high altitude, and thus the supporting base 21 includes two supporting frames 211 having a certain height and two bearings 212 respectively disposed at the ends of the supporting frames 211. The structure of the supporting frame 211 may be a tripod, and certainly, other structures are also possible, however, the supporting frame 211 and the bearing 212 should be known to those skilled in the art, and are not described herein again.

The dryer 22 includes a drying chamber 221, two rotating shafts 222 respectively disposed at both sides of the drying chamber 221 and penetrating the bearings 212, and a driven pulley 223 disposed on one of the two rotating shafts 222. The drying chamber 221 may be spherical or barrel-shaped, and may be selected according to actual requirements. The drying chamber 221 has a double-layer structure, and includes an inner wall 224, an outer wall 225 disposed outside the inner wall 224 and spaced from the inner wall 224, an air inlet pipe 226 communicated with the outer wall 225, an air outlet pipe 227 communicated with the outer wall 225, a feeding port 228 disposed between the inner and

outer walls

224, 225, and a discharging port 229 disposed between the inner and

outer walls

224, 225. The inner wall 224 is a hollow body that may be made of a highly thermally conductive material, such as an aluminum alloy. The outer wall 225 is disposed outside the inner wall 224, and may be made of a thermal insulation material, such as a resin material. The inner and

outer walls

224, 225 are connected together by the inlet and

outlet ports

228, 229. The air inlet pipe 226 and the air outlet pipe 227 are respectively sleeved in the two rotating shafts 222 and are communicated with the gap between the inner wall 224 and the outer wall 225, so that hot steam coming from the air inlet pipe 226 can enter the gap between the inner wall 224 and the outer wall 225, the inner wall 224 is heated, and the purpose of drying materials contained in the inner wall 224 is achieved. Thus, the intake pipe 226 is in communication with a steam device (not shown). It is contemplated that the air inlet conduit 22 is slidably coupled to the steam device in order to facilitate rotation of the air inlet conduit 226. The air outlet pipe 227 is communicated with the outside and used for exhausting air. The inlet 228 and the outlet 229 have the same structure and operation principle, and the structure and operation principle of the inlet 228 are only described as an example. The feed inlet 228 includes a feed through opening 2281 formed between the inner and

outer walls

224, 225, a ring magnet 2282 fixed to a side wall of the feed through opening 2281, and a magnetic feed cover 2283. The feeding cover 2283 is covered on the circular magnet 2282, and when an external force acts on the discharging cover, the feeding cover 2283 is separated from the circular magnet 2282, so that discharging can be realized. In a similar way, the discharging hole 229 also comprises a discharging through hole 2291, a discharging magnet 2292 and a discharging cover 2293. The working principle of the discharge port 229 is the same as that of the feed port 228, and the description thereof is omitted. The angle between the central axis of the feed port 228 and the discharge port 229 is 90 degrees, so that when the discharge port 229 is facing downward, the central axis of the feed port 228 is horizontal to facilitate discharging and feeding. The two rotating shafts 222 are fixed to two axial ends of the outer wall 225 and are inserted into the bearings 212 of the support frame 21. The driven pulley 223 is fixed to one of the two rotation shafts 222 so as to be rotatably driven by the driving motor 23, thereby stirring the material contained in the inner wall 224.

The driving motor 23 should be a prior art which outputs power under the driving of electric power, and will not be described in detail herein. In the present embodiment, the output of the driving motor 23 and the driven pulley 223 are driven by a belt, which should be known to those skilled in the art.

The transmission 24 is used for transmitting power between the output of the driving motor 23 and the driven wheel 22, and may be implemented in various conventional manners, such as belt transmission, gear transmission, etc., which should be known to those skilled in the art and will not be described in detail herein. In the present embodiment, the transmission 24 is a belt transmission.

The feeding mechanism 30 includes a feeding support seat 31, a feeding pipe 32 mounted on the feeding support seat 31, a storage box 35 communicated with the feeding pipe 32, a feeding pipe pushing mechanism 33 disposed on the feeding pipe 32, and a feeding pushing mechanism 34. The feeding support seat 31 comprises a gantry groove 311 arranged on the base 10, at least two brackets 312 arranged on the gantry groove 311, and at least two sleeves 313 arranged on the brackets 312. The gantry slot 311 is fastened on the base 10, i.e. the opening faces the base 10. The support 312 may be a triangular support, or may be a support of other forms, such as a rectangular body. The sleeve 313 is disposed at the end of the support 312 for sleeving the feeding tube 32. The feeding pipe 32 is a hollow pipe, and is communicated with the storage box 35 and is arranged on one sleeve 313 in a penetrating way. The outer diameter of the feeding pipe 32 is equivalent to the inner diameter of the ring-shaped magnet 2282 and is coaxially arranged, so that the feeding pipe 32 can be inserted into the ring-shaped magnet 2282, and the feeding cover 2283 is pushed open. The feeding pipe pushing mechanism 33 includes a rack 331 disposed on one of two side walls of the gantry groove 311, a driving gearwheel 332 engaged with the rack 331, a driven large bevel gear 333 disposed coaxially with the driving gearwheel 332, a driving bevel gear 334 for driving the driven large bevel gear 333 to rotate, and a motor 335 for driving the driving bevel gear 334 to rotate. It is conceivable to provide the drive bevel gear 334 on the driven large bevel gear 333 for the purpose of space saving. It can be understood that the motor 335 can directly drive the driving gearwheel 332 to drive the rack 331 to move, and when the motor 335 rotates forward and backward, the feeding pipe 32 can reciprocate forward and backward, and then the feeding propulsion mechanism 34 can automatically feed the materials. The feeding and pushing mechanism 34 includes an internally threaded sleeve 341 having an internal thread, a jack screw 342 inserted into the internally threaded sleeve 341 and having an external thread engaged with the internally threaded sleeve 341, a feeding pipe gear 343 fitted over an outer side wall of the internally threaded sleeve 341, a driven bevel pinion 344 engaged with the feeding pipe gear 343, and a drive pinion 345 engaged with the driven bevel pinion 344. The drive pinion 345 is driven by the drive bevel gear 334. As described above, the main bevel gear 334 is driven by the motor 335. Therefore, when the motor 335 outputs, the driving bevel gear 334 rotates, so as to drive the driving pinion 345 and the driven bevel gear 333 to rotate, and further drive the driven bevel pinion 344 and the driving gear 332 to rotate, respectively, and further drive the feeding pipe gear 343 and the rack 331 to move. When the rack 331 is moved, the feeding tube 32 can be pushed in and pulled out of the feeding hole 228. When the feed pipe gear 343 rotates, the ejector screw 342 can be pushed forward or backward, so that the material can be ejected into the feed port 228, or retracted to prepare for the next ejection. The motor 335 may be a stepping motor, which can realize forward rotation and reverse rotation, and is well known to those skilled in the art, and will not be described in detail herein.

The blanking mechanism 40 includes two first lifting gears 41 disposed on the base 10 and engaged with each other, a second lifting gear 42 disposed on the base 10 and engaged with the two first lifting gears 41, a third lifting gear 43 coaxially and fixedly disposed on the second lifting gear 42, a clockwork 44 disposed on the third lifting gear 43, a short rack 45 fixedly disposed on the gantry 311, two screws 46 coaxially and fixedly disposed with the two first lifting gears 41, respectively, a lifting frame 47 mounted on the screws 46, two nuts 48 disposed on the lifting frame 47 and screwed on the screws 46, and a discharge pipe 49 disposed on the lifting frame 47. The short rack 45 includes a tooth section 451 engaged with the third rising gear 43 and a smooth section 452 connected to the tooth section 451. The tooth section 451 is disposed on a side of the short rack 45 away from the gantry groove 311, that is, the smooth section 452 is disposed between the tooth section 451 and the gantry groove 311, so that when the gantry groove 311 moves away from the feeding material 228, the tooth on the short rack 45 is engaged with the third lifting gear 43 to drive the third lifting gear 43 to rotate. When the third rising gear 43 rotates, the second rising gear 43 is driven to rotate, and the clockwork spring 44 is wound. The spring mechanism 44 is a conventional art, and is a mechanism for winding up a sheet-like steel strip and generating power by gradually releasing the spring force. When the third lifting gear 43 rotates, the second lifting gear 42 is rotated together, thereby driving the two first lifting gears 41 to rotate. When the first elevating gear 41 rotates, the screw 46 is rotated together. While the screw 46 is rotated, the elevating frame 47 provided with the nut 48 is driven to ascend, so that the discharge pipe 49 is inserted into the discharge port 229 and the discharge cover 2293 is pushed open to start discharging. When the gantry slot 311 moves toward the dryer 22, the smooth section 452 of the short rack 45 contacts the third rising gear 43, so that the third rising gear 43 loses its binding force, and thus the clockwork 44 is gradually loosened by its elastic force. During the unwinding of the clockwork spring 44, the third rising gear 43 rotates in reverse together with the second rising gear 42, thereby rotating the first rising gear 41 in reverse. In the process of the reverse rotation of the first lifting gear 41, the screw 46 drives the nut 47 to descend, and further drives the lifting frame 47 and the discharge pipe 49 arranged on the lifting frame 47 to descend, so that the automatic blanking purpose of the blanking mechanism 40 is realized. Also, the central axis of the tapping pipe 49 must therefore coincide with the central axis of the tapping opening 229.

The control device 50 is electrically connected to the driving motor 23 and the motor 335, and controls the driving motor 23 and the motor 335 to rotate forward and backward, so that the dryer 22 rotates forward or backward to achieve the purpose of drying fully. Meanwhile, due to the forward rotation and the reverse rotation of the motor 335, the feeding mechanism 30 can perform feeding or return to the original position to prepare for the next feeding. While the feeding mechanism 30 is feeding, the blanking mechanism 40 returns to the original position, and at a certain time when the feeding mechanism 30 returns to the original position, the tooth section 451 of the short rack 45 of the blanking mechanism 40 engages with the third rising gear 43, so as to drive the discharging pipe 49 of the blanking mechanism 40 to be inserted into the discharging port 229 to complete discharging. This can be achieved by programming as to when the drive motor 23 and motor 335 are rotating in the forward direction and in the reverse direction, and the length of time for the forward or reverse rotation. The above programming can be easily performed by those skilled in the art using the existing programming languages, such as VB, VC, etc., based on the knowledge of the spirit of the present invention.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the scope of the present invention, and any modifications, equivalents or improvements that are within the spirit of the present invention are intended to be covered by the following claims.
