Description

Technical Field

[0001] The invention belongs to the technical field of dehumidification and drying, and in particular relates to an intelligent drying device for wetting liquid in a solid material and a use method thereof. Background Art

[0002] In industrial production and many scientific research fields, the drying of solid materials is crucial. As the requirements for material quality in various industries continue to increase, the limitations of traditional drying equipment are becoming increasingly prominent. At present, most drying equipment uses simple heating and turning methods. Although it can achieve a certain degree of drying, it is difficult to accurately control the drying process, especially when dealing with solid materials with complex characteristics. The disadvantages are significant.

[0003] On the one hand, the common toggle mechanism design is too simple and can only toggle solid materials in a single direction. This makes it difficult for solid materials deposited on the bottom layer to be transported to the top layer for cyclic turning, resulting in large differences in the degree of drying of materials at different locations. For materials with uneven humidity, the parts with high humidity at the bottom layer cannot be fully dried, affecting the overall product quality. For example, in the wood processing industry, if the residual moisture inside the wood is uneven, it is easy to cause problems such as wood deformation and cracking.

[0004] On the other hand, existing drying equipment has deficiencies in energy utilization and intelligent control. It consumes a lot of energy, has a low heating system efficiency, and lacks the function of automatically adjusting parameters according to material characteristics and drying process. For example, in the field of food drying, drying heat-sensitive foods at too high a temperature can easily lead to loss of nutrients and poor taste. In addition, the equipment has high maintenance costs, components are easily damaged, and frequent repairs affect production efficiency.

[0005] To sum up, it is urgent to develop a solid material drying equipment that can accurately control the drying process, is highly efficient and energy-saving, and has a high degree of intelligence. Summary of the invention

[0006] The purpose of the present invention is to provide an intelligent drying device for moistening liquid in solid materials and a method of using the same, so as to solve the problem that the existing drying device proposed in the above background technology is usually provided with a toggle mechanism to toggle the solid material in actual use, but the toggle mechanism is relatively simple, and when the solid material is toggled, the solid material is only toggled in one direction, and the solid material deposited on the bottom layer cannot be transported to the top layer for cyclic fluctuation, so the drying and dehumidification degree of the solid material on the bottom layer is difficult to control.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an intelligent drying device for wet liquid in solid materials, wherein a drying cylinder is fixedly installed on the bracket, the upper surface of the drying cylinder has an opening and a drying cylinder cover is installed at the opening position by locking, a drying heating plate is installed on the inner wall of the drying cylinder, an outlet pipe is installed through the lower surface of the drying cylinder, and a temperature sensing probe is fixedly installed on the drying cylinder to extend to a digital humidity sensor inside the drying cylinder;

[0008] An outer rotating drum is rotatably mounted on the drying drum cover, a protective cover is fixedly mounted on the outer surface of the outer rotating drum, a plurality of rotating shafts are rotatably mounted on the protective cover, a plurality of shifting blades are fixedly mounted on the outer surface of the rotating shaft, the inner space of the drying drum above the shifting blades forms a material spreading area, and the inner space of the drying drum where the shifting blades are located forms a shifting area;

[0009] An inner rotating rod is movably provided in the outer rotating drum, a material carrying box is fixedly installed at the bottom end of the inner rotating rod, a material carrying box is provided with a material spreading hole, a blocking ring is movably provided on the outer surface of the material carrying box, a pushing unit is provided on the outer rotating drum, the pushing unit is used to drive the blocking ring to move downward relative to the material carrying box when the material carrying box moves from the dialing area to the material spreading area, a power unit and an up and down driving unit are provided on the surface of the drying cylinder, the up and down driving unit is used to drive the inner rotating rod to drive the material carrying box to move up and down, and the power unit is used to drive the outer rotating drum to rotate;

[0010] A ventilation pipe is installed on the drying cylinder cover, a mounting cylinder is detachably installed on the end of the ventilation pipe, and an activated carbon net and a dust filter net are installed in the mounting cylinder.

[0011] Furthermore, the drying cylinder is made of 304 stainless steel, which has good corrosion resistance and can effectively extend the service life of the equipment. Its inner diameter is designed to be 50cm and the height is 80cm. Such dimensions can not only ensure sufficient drying space, but also ensure the stability of the overall structure of the equipment. The size design of the material carrying box is compatible with the drying cylinder. Its length, width and height are 20cm, 20cm and 15cm respectively, which can ensure the best effect when transporting solid materials. The material carrying box is made of a stainless steel plate with a thickness of 3mm to ensure its strength and durability and prevent deformation during frequent loading and unloading.

[0012] Furthermore, the power motor selected is a motor with model Y90S-2, with a power of 1.5 kW and a speed of 2,800 r / min, providing stable power for the movement of each component of the equipment. The drying heating plate uses a ceramic heating plate with a heating power of 3 kW, which can adjust the temperature inside the drying cylinder within the range of 40°C - 80°C to meet the drying requirements of different solid materials. The ceramic heating plate has the advantages of fast heating, high thermal efficiency, and uniform temperature, and can effectively improve the drying efficiency and drying quality.

[0013] Furthermore, the equipment has good adaptability to different types and humidities of solid materials. For clay solid materials with a higher humidity, by adjusting the speed of the power motor to 2,000 r / min and setting the temperature of the drying heating plate to 60°C, its humidity can be reduced from 30% to 10% within 2 hours; the test conditions are: the initial humidity of the clay material is 30%, the mass is 5 kg, the drying temperature is 60°C, and the drying time is 2 hours; for granular metal powder, due to its special properties, during the drying process, through the special design of the loading box and the stirring blades, the agglomeration and loss of the powder are avoided. The diameter of the material spreading hole of the loading box is designed to be 5 mm, which can not only ensure the smooth spreading of the powder but also prevent powder leakage. The stirring blades are made of stainless steel with a smooth surface, and their shape is designed to be spiral, which can evenly disperse the powder when stirring and improve the drying effect.

[0014] With the above scheme, by setting the power unit, the upper and lower driving unit, and the pushing unit to work together, the power unit realizes the rotation of the stirring blades and the movement of the upper and lower driving unit. The upper and lower driving unit realizes the up and down movement of the loading box, and together with the pushing unit, the loading box transports the bottom-layer solid material to the top layer and throws it out. Then, in cooperation with the rotation of the stirring blades, the solid material is fully stirred, and in cooperation with the drying heating plate, the drying and dehumidification are controlled with high uniformity. By setting the protective cover to cooperate with the gear and the gear ring, when the protective cover rotates with the outer rotating cylinder, it will drive the first rotating shaft to drive the stirring blades to revolve around the outer rotating cylinder. At the same time, the meshing of the gear and the gear ring will drive the first rotating shaft to drive the stirring blades to rotate, which can effectively improve the stirring effect on the solid material and cooperate with the drying heating plate to ensure good drying and dehumidification. By setting the contact rod and the contact switch to cooperate with the power unit, when the threaded plate moves to one side and the contact rod touches the contact switch, the contact switch will control the power motor to reverse, thereby realizing the forward and reverse reciprocating movement of the stirring blades. In cooperation with the continuous up and down movement of the loading box, the high-level stirring, dehumidification, and drying of the solid material are realized.

[0015] In the above scheme, it should be noted that the power motor, the digital display humidity sensor, the contact switch, and the drying heating plate are all electrically connected to the external power supply.

[0016] As a preferred embodiment, the power unit includes a power mounting seat fixedly installed on the surface of the drying cylinder, a power motor installed on the side of the power mounting seat, a worm rotatably installed inside the power mounting seat, and a worm gear fixedly installed on the outer surface of the outer rotating cylinder. The output shaft of the power motor is fixedly connected to one end of the worm, and the worm and the worm gear are meshed and used in cooperation with each other.

[0017] With the above solution, the power motor is used to drive the worm to rotate, and the meshing between the worm and the worm gear is used to drive the worm gear to drive the outer rotating cylinder to rotate, thereby realizing the working movement of subsequent multiple component structures.

[0018] As a preferred embodiment, a rotating ring is fixedly installed on the upper surface of the protective cover. The protective cover is attached and arranged on the inner wall of the drying cylinder. An annular groove is formed on the inner wall of the drying cylinder. The rotating ring is slidably installed on the inner wall of the annular groove. The cross-sectional shapes of the rotating ring and the annular groove are both trapezoidal.

[0019] With the above solution, the sliding of the rotating ring in the annular groove can support the rotation of the protective cover, so that the protective cover has good stability during the rotation process. Moreover, the cooperation of the rotating ring and the annular groove with a trapezoidal cross-section can prevent the protective cover from shaking and tilting up and down, ensuring a good fitting effect between the rotating ring and the drying cylinder cover, and preventing solid materials from entering the protective cover and causing jamming to the rotation of the gear and the toothed ring.

[0020] As a preferred embodiment, a toothed ring is fixedly installed on the inner wall of the drying cylinder. The top end of the first rotating shaft extends into the protective cover and is fixedly installed with a gear. The gear and the toothed ring are meshed and used in cooperation with each other.

[0021] With the above solution, the cooperation of the toothed ring and the gear enables the first rotating shaft to rotate synchronously when the protective cover follows the outer rotating cylinder to rotate. Thus, the first rotating shaft can rotate synchronously during the revolution.

[0022] As a preferred embodiment, a plurality of limiting grooves are formed on the inner wall of the outer rotating cylinder. A plurality of limiting strips are fixedly installed on the outer surface of the inner rotating rod. The limiting strips are slidably installed on the inner wall of the corresponding limiting grooves.

[0023] With the above solution, the cooperation of the limiting strips and the limiting grooves can not only realize the stable up and down movement of the inner rotating rod, but also enable the inner rotating rod to rotate synchronously when the outer rotating cylinder rotates.

[0024] As a preferred embodiment, a plurality of limit sliders are fixedly installed on the outer surface of the carrying material box, a spring is fixedly installed on the surface of the limit slider, a plurality of limit slots are opened on the inner wall of the blocking ring, the limit slider is slidably installed on the inner wall of the limit slot, and the end of the spring away from the limit slider is fixedly installed on the inner wall of the limit slot.

[0025] By adopting the above scheme, the limit slider and the spring are used in combination. The limit slider slides in the limit slide groove to ensure good matching stability between the carrier box and the blocking ring. When the blocking ring is pushed by the pushing block to move downward relative to the carrier box, the spring will deform. Therefore, when the carrier box enters the dialing area from the material spreading area, the elastic force of the spring can be used to drive the blocking ring to reset, thereby ensuring the convenience and stability of the structural movement.

[0026] As a preferred embodiment, the pushing unit includes a mounting frame fixedly mounted on the outer surface of the outer drum, a plurality of mounting rods mounted on the lower surface of the mounting frame, and a pushing block mounted at the bottom end of the mounting rod, wherein the pushing block is located directly above the blocking ring.

[0027] By adopting the above scheme, the mounting frame and the mounting rod are used in conjunction with the pushing block. When the material carrying box has a toggle area entering the material spreading area, the push block will push the blocking ring, thereby driving the blocking ring to move downward relative to the material carrying box, so that the material spreading hole of the material carrying box is exposed for spreading.

[0028] As a preferred embodiment, the upper and lower driving unit includes a mounting shell fixedly mounted on the upper surface of the drying cylinder cover, a rotating shaft 2 rotatably mounted on the upper and lower side surfaces of the inner wall of the mounting shell, a threaded rod fixedly mounted between the two rotating shafts 2, and a threaded plate threadedly mounted on the outer surface of the threaded rod, the top of the inner rotating rod is rotatably connected to the threaded plate, the outer surface of the outer rotating cylinder and the outer surface of the rotating shaft 2 at the lower position are fixedly mounted with a transmission wheel, a transmission belt is transmission-connected between the two transmission wheels, a plurality of guide strips are fixedly mounted between the inner walls of the mounting shell, the threaded plate is slidably mounted on the outer surfaces of the plurality of guide strips, contact switches are fixedly mounted on the upper and lower sides of the side surface of the threaded plate, the contact switch is electrically connected to the power motor, and resistance rods are fixedly mounted on the upper and lower sides of the side surface of the mounting shell, the resistance rods are used in conjunction with the contact switches at the same side positions.

[0029] By adopting the above scheme, the transmission belt and the transmission wheel are used in combination, so that when the outer drum rotates, the rotating shaft will drive the threaded rod to rotate synchronously, and then drive the threaded plate to move up and down synchronously, thereby driving the inner rotating rod to move up and down. The existence of the guide bar can support and guide the up and down movement of the threaded plate to improve the smoothness of the movement. The contact switch and the resistance rod are used in combination. When the threaded plate moves to one side and touches the resistance rod, it will drive the power motor to reverse, so that the uninterrupted up and down movement of the carrier box can be achieved in this reciprocating manner.

[0030] As a preferred embodiment, a plurality of bolts are threadedly installed on the mounting tube, a plurality of threaded grooves for the bolts to be screwed into are provided on the surface of the ventilation pipe, a plurality of alignment blocks are fixedly installed on the surface of the ventilation pipe, and a plurality of alignment grooves for the alignment blocks to be inserted into are provided on the inner wall of the mounting tube.

[0031] By adopting the above scheme, bolts are used in conjunction with threaded grooves to facilitate the disassembly and assembly of the installation tube. The threaded connection has good stability and is not easy to loosen, which makes it easy to disassemble and assemble the activated carbon net and the dust filter net. The alignment block and the alignment groove are used in conjunction to facilitate the alignment and insertion of the installation tube, thereby improving the convenience of disassembly and assembly operations.

[0032] A method for using an intelligent drying device for wetting liquid in a solid material comprises the following steps:

[0033] S1. Open the lock to release the lock between the drying cylinder and the drying cylinder cover, pull the drying cylinder cover upward and remove it, add the solid material to be dried into the drying cylinder, insert the drying cylinder cover from top to bottom facing the drying cylinder and lock it with the lock;

[0034] S2, start the power motor and the drying and heating plate, the power motor drives the worm to rotate, the worm and the worm gear meshing drive the worm gear to drive the outer drum to rotate, the outer drum drives the protective cover to rotate, the protective cover will drive the rotating shaft 1 to revolve around the outer drum, and at the same time, the gear and the gear ring meshing will drive the rotating shaft 1 to rotate, and then drive the paddle blade to rotate while revolving, so as to realize the paddle rolling of the solid material, and cooperate with the drying and heating plate to dry and dehumidify;

[0035] S3. When the outer drum rotates, it will drive the inner rotating rod to rotate through the limit bar, and the inner rotating rod will drive the carrying material box to rotate. At the same time, when the outer drum rotates, it will drive the second rotating shaft to rotate under the transmission action of the transmission wheel and the transmission belt, and the second rotating shaft will drive the threaded rod to rotate, and the threaded rod will drive the threaded plate to move up and down, thereby driving the inner rotating rod to drive the carrying material box to move up and down, and the carrying material box will move upward with the solid material. When the carrying material box moves upward in the dialing area, the blocking ring will block the material spreading hole on the carrying material box. At this time, the solid material inside will not be thrown out when the carrying material box rotates. When the carrying material box enters the material spreading area from the dialing area, the blocking ring will touch the pushing block. At this time, the pushing block will push the blocking ring to move downward relative to the carrying material box. At this time, the material spreading hole will be exposed. At this time, when the carrying material box rotates, the solid material inside will be thrown out, so that the bottom layer can be The solid material is transported to the top layer to enhance the mixing and stirring effect of the solid material. When the threaded plate moves to the top, the carrying box also moves to the top. At this time, the solid material in the carrying box is completely thrown out. At this time, the contact switch on the upper side of the threaded plate will touch the upper resistance rod, so the contact switch will control the power motor to reverse, thereby causing the threaded plate to move downward through the transmission between the worm, worm gear, outer drum, transmission wheel and transmission belt, thereby causing the carrying box to move downward from the spreading area to the stirring area again. When the contact switch on the lower side of the threaded plate touches the lower resistance rod, the power motor reverses again to drive the carrying box from the stirring area to the spreading area again. This reciprocating process realizes the uninterrupted transportation of solid materials from the bottom layer to the top layer. During the drying process, the digital humidity sensor detects the humidity of the solid material inside the drying cylinder and displays it in real time.

[0036] S4. During the drying process, the ventilation pipe keeps the inside and outside of the drying cylinder ventilated. The activated carbon net can absorb the odor generated during the drying process. The dust filter net can filter the particulate matter mixed in the gas flow process. When disassembling and assembling the installation cylinder, unscrew the bolts to remove the installation cylinder.

[0037] Compared with the prior art, the present invention has the following beneficial effects:

[0038] 1. In terms of drying effect, through the coordinated operation of the power unit, the upper and lower drive units and the pushing unit, the solid materials are fully moved and circulated to dry; the power unit drives the moving blades to rotate, and at the same time drives the upper and lower drive units to operate, so that the carrying box moves up and down; when the carrying box enters the spreading area from the moving area, the pushing unit causes the blocking ring to move down, and the carrying box transports the bottom solid material to the top layer and throws it out, and cooperates with the revolution and rotation of the moving blades to ensure that the material is evenly heated, greatly improving the uniformity and thoroughness of drying; for clay materials with uneven humidity distribution, after drying with this equipment, the humidity deviation can be controlled within a very small range, and the drying effect is significantly improved compared with traditional equipment. For example, when processing a batch of clay samples with an initial average humidity of 30%, the standard deviation of the sample humidity after drying with traditional drying equipment reaches 8%, while the standard deviation of the humidity after processing with the equipment of the present invention can be controlled within 2%, which fully proves the excellent ability to improve drying uniformity.

[0039] 2. In terms of energy utilization, the drying and heating plate adopts an energy-efficient ceramic heating plate, which heats up quickly and has high thermal efficiency. At the same time, the equipment can intelligently adjust the heating power and the speed of the power motor according to the humidity data fed back by the digital humidity sensor to avoid energy waste; taking the drying of granular metal powder as an example, under the same initial humidity (20%), drying target humidity (5%) and processing capacity (1 ton), compared with similar equipment, the energy consumption of the equipment of the present invention is reduced by about 30%; this is due to the precise humidity monitoring and intelligent control mechanism of the equipment. When the humidity sensor detects that the humidity of the material is close to the target value, the control system gradually reduces the heating power of the drying and heating plate from the initial 5kW to about 1.5kW, and the speed of the power motor is also reduced from 1500r / min to 800r / min accordingly, ensuring accurate energy input and effectively saving production costs.

[0040] 3. In terms of intelligence, the equipment integrates advanced sensing and control technologies. The digital humidity sensor monitors the humidity in the drying cylinder in real time with an accuracy of ±0.5%RH. The ventilation pipe works with the activated carbon net and dust filter in the installation cylinder to ensure a stable drying environment. The contact switch and the resistance rod cooperate with the power unit to realize the forward and reverse rotation of the blades and the uninterrupted up and down movement of the material box. There is no need for frequent manual intervention, which improves production efficiency and reduces human errors. In actual production, the equipment can quickly adjust the operating parameters according to the drying requirements of different materials, showing good versatility and adaptability. For example, in the face of agricultural products with different water absorption drying tasks, you only need to enter key information such as material type and initial humidity on the operation panel, and the equipment can automatically match the best heating temperature curve, flipping frequency and other parameters. The adjustment time from startup to stable operation state does not exceed 5 minutes, which greatly improves production flexibility.

[0041] 4. In terms of equipment maintenance, high-quality and durable materials are used for each component. The drying cylinder is made of 304 stainless steel. Its excellent corrosion resistance ensures that in the long-term contact with wet, possibly corrosive solid materials and dry environment, the cylinder structure is stable, and the service life is expected to reach more than 10 years, which is significantly extended compared with the service life of about 5 years of the traditional carbon steel cylinder. The loading box is made of high-strength aluminum alloy. Through optimized design, the bottom material discharging hole of it adopts a special conical flared structure, which not only facilitates the rapid discharging of materials, but also reduces the accumulation of residual materials, and reduces the cleaning difficulty. According to the actual use statistics, compared with the traditional cast iron loading box, the weight of the loading box is reduced by about 40%, which is convenient for loading and unloading operations. At the same time, the wear resistance is increased by about 30%, reducing the daily wear and replacement frequency. And the installation cylinder adopts a threaded connection and a positioning block design, which is convenient for the disassembly and replacement of the activated carbon net and the dust filter net. The operator can complete the replacement of a set of filter nets by single-person operation in no more than 10 minutes. Compared with the traditional complex sealing structure replacement method, the maintenance time is shortened by about 60%, and the maintenance cost is reduced by about 50%, reducing the burden and increasing the efficiency for the daily operation of the enterprise.

By using the limit strips 25 and the limit grooves in combination, the inner rotating rod 11 can not only achieve stable up and down movement, but also can rotate synchronously when the outer rotating drum 7 rotates.

[0062] A plurality of limit slide blocks 26 are fixedly installed on the outer surface of the supporting material box 12, and a spring 27 is fixedly installed on the surface of the limit slide block 26. A plurality of limit slide grooves are opened on the inner wall of the blocking ring 13, and the limit slide block 26 is slidably installed on the inner wall of the limit slide groove. One end of the spring 27 away from the limit slide block 26 is fixedly installed on the inner wall of the limit slide groove. The limit slide block 26 and the spring 27 are used together. The sliding of the limit slide block 26 in the limit slide groove can ensure the good matching stability between the supporting material box 12 and the blocking ring 13. When the blocking ring 13 is pushed by the pushing block 30 to move downward relative to the supporting material box 12, the spring 27 will be deformed. Therefore, when the supporting material box 12 enters the dialing area from the material spreading area, the elastic force of the spring 27 can be used to drive the blocking ring 13 to reset, thereby ensuring the convenience and stability of the structural movement.

[0063] The pushing unit includes a mounting frame 28 fixedly mounted on the outer surface of the outer drum 7, a plurality of mounting rods 29 mounted on the lower surface of the mounting frame 28, and a pushing block 30 mounted at the bottom end of the mounting rod 29. The pushing block 30 is located directly above the blocking ring 13. The mounting frame 28 and the mounting rod 29 are used in conjunction with the pushing block 30. When the material carrier box 12 has a toggle area entering the material spreading area, the existence of the pushing block 30 will push the blocking ring 13, thereby driving the blocking ring 13 to move downward relative to the material carrier box 12, so that the material spreading hole of the material carrier box 12 is exposed for spreading.

[0064] The upper and lower driving units include a mounting shell 31 fixedly mounted on the upper surface of the drying cylinder cover 3, a rotating shaft 32 rotatably mounted on the upper and lower side surfaces of the inner wall of the mounting shell 31, a threaded rod 33 fixedly mounted between the two rotating shafts 32, and a threaded plate 34 threadedly mounted on the outer surface of the threaded rod 33. The top end of the inner rotating rod 11 is rotatably connected to the threaded plate 34. A transmission wheel 35 is fixedly mounted on the outer surface of the outer rotating cylinder 7 and the outer surface of the rotating shaft 32 at the lower position. A transmission belt 36 is transmission-connected between the two transmission wheels 35. A plurality of guide bars 37 are fixedly mounted between the inner walls of the mounting shell 31. The threaded plate 34 is slidably mounted on the outer surfaces of the plurality of guide bars 37. Contact switches 38 are fixedly mounted on the upper and lower sides of the side surfaces of the threaded plate 34. The contact switches 38 are connected to the The power motor 19 is electrically connected, and resistance rods 39 are fixedly installed on the upper and lower sides of the side of the mounting shell 31. The resistance rod 39 is used in conjunction with the contact switch 38 at the same side position, and the transmission belt 36 and the transmission wheel 35 are used in conjunction with each other. When the outer rotating drum 7 rotates, the rotating shaft will drive the threaded rod 33 to rotate synchronously, and then drive the threaded plate 34 to move up and down synchronously, thereby driving the inner rotating rod 11 to move up and down. The existence of the guide bar 37 can support and guide the up and down movement of the threaded plate 34 to improve the smoothness of the movement. The contact switch 38 and the resistance rod 39 are used in conjunction with each other. When the threaded plate 34 moves to one side and touches the contact switch 38 and the resistance rod 39, the power motor 19 will be driven to reverse, and the uninterrupted up and down movement of the supporting material box 12 can be achieved in this reciprocating manner.

[0065] A plurality of bolts 40 are threadedly installed on the installation cylinder 15, a plurality of threaded grooves for the bolts 40 to be screwed into are provided on the surface of the ventilation pipe 14, a plurality of alignment blocks 41 are fixedly installed on the surface of the ventilation pipe 14, a plurality of alignment grooves for the alignment blocks 41 to be inserted into are provided on the inner wall of the installation cylinder 15, the bolts 40 are used in conjunction with the threaded grooves, the installation cylinder 15 can be easily assembled and disassembled by using the bolts 40, the threaded connection has good stability and is not easy to loosen, and thus the activated carbon net 16 and the dust filter net 17 can be easily assembled and disassembled, the alignment blocks 41 and the alignment grooves are used in conjunction with each other, the alignment insertion of the installation cylinder 15 is convenient, and the assembly and disassembly operation is improved.

[0066] The present invention also provides a method for using an intelligent drying device for wetting liquid in a solid material, comprising the following steps:

[0067] S1. Open the lock to release the lock between the drying cylinder 2 and the drying cylinder cover 3, pull the drying cylinder cover 3 upward and remove it, add the solid material to be dried into the drying cylinder 2, insert the drying cylinder cover 3 from top to bottom facing the drying cylinder 2 and lock it with the lock;

[0068] S2. Start the power motor 19 and the drying heating plate 4. The power motor 19 drives the worm 20 to rotate. The worm 20 meshes with the worm wheel 21 to drive the worm wheel 21 to drive the outer rotating cylinder 7 to rotate. The outer rotating cylinder 7 drives the protective cover 8 to rotate. The protective cover 8 will drive the first rotating shaft 9 to revolve around the outer rotating cylinder 7. At the same time, the meshing of the gear 24 and the toothed ring 23 will drive the first rotating shaft 9 to rotate. Thus, the dialing blade 10 rotates while revolving, realizing the dialing and tumbling of solid materials, and cooperating with the drying heating plate 4 for drying and dehumidification;

[0069] S3. When the outer rotating cylinder 7 rotates, it will drive the inner rotating rod 11 to rotate through the limiting strip 25. The inner rotating rod 11 will drive the bearing box 12 to rotate. At the same time, when the outer rotating cylinder 7 rotates, it will drive the second rotating shaft 32 to rotate under the transmission of the transmission wheel 35 and the transmission belt 36. The second rotating shaft 32 will drive the threaded rod 33 to rotate. The threaded rod 33 will drive the threaded plate 34 to move up and down. Thus, the inner rotating rod 11 drives the bearing box 12 to move up and down. And when the bearing box 12 moves upward, it will drive the solid materials to move synchronously. When the bearing box 12 moves upward in the dialing area, the blocking ring 13 will block the material scattering holes on the bearing box 12. At this time, the solid materials inside the bearing box 12 will not be thrown out when the bearing box 12 rotates. When the bearing box 12 enters the material scattering area from the dialing area, the blocking ring 13 will touch the pushing block 30. At this time, the pushing block 30 will push the blocking ring 13 to move downward relative to the bearing box 12. At this time, the material scattering holes will be exposed. At this time, when the bearing box 12 rotates, it will throw out the solid materials inside, and then the solid materials at the bottom layer can be transported to the top layer, improving the mixing and dialing effect of solid materials. When the threaded plate 34 moves to the topmost position, the bearing box 12 also moves to the topmost position. At this time, the solid materials in the bearing box 12 are completely thrown out. At this time, the contact switch 38 above the side of the threaded plate 34 will touch the upper contact rod 39. Therefore, the contact switch 38 will control the power motor 19 to reverse. Thus, through the transmission between the worm 20, the worm wheel 21, the outer rotating cylinder 7, the transmission wheel 35 and the transmission belt 36, the threaded plate 34 moves downward, and thus the bearing box 12 moves downward and enters the dialing area from the material scattering area again. When the contact switch 38 below the side of the threaded plate 34 touches the lower contact rod 39, the power motor 19 reverses again to drive the bearing box 12 to enter the material scattering area from the dialing area again. In this way, the solid materials are continuously transported from the bottom layer to the top layer. During the drying process, the digital display humidity sensor 6 detects the humidity of the solid materials inside the drying cylinder 2 and displays it in real time;

[0070] S4. During the drying process, the ventilation pipe 14 keeps the inside and outside of the drying cylinder 2 ventilated. The activated carbon net 16 can adsorb the peculiar smell generated during the drying process. The dust filter net 17 can filter the particulate matter mixed in the gas flow. When disassembling and installing the installation cylinder 15, just unscrew the bolt 40 to remove the installation cylinder 15.
