Description

Technical Field

[0001] The present invention relates to the technical field of material drying, in particular to a material drying device and a drying method thereof. Background Art

[0002] During the processing of some small-volume materials, the materials will be cleaned to remove impurities adhering to the surface during the processing. At the same time, in order to facilitate the subsequent packaging of the workpiece materials, the materials need to be dried. However, the existing material drying devices still have some shortcomings.

[0003] In the prior art, there is a material drying device with publication number CN106802070A. Compared with the existing dryer, this material drying device uses two symmetrically installed blowers to speed up the air intake speed. At the same time, the air is introduced in all directions through the air intake pipe of the mountain-shaped structure. Compared with a single air inlet, the drying is more uniform, and the hot air is recycled under the action of the return pipe. With the heating plates distributed at equal intervals, the drying speed is fast. The windproof cloth and the heat insulation layer effectively prevent the loss of internal heat. The overall drying effect is good, the structure is stable, the operation is simple, and it is easy to use. However, when in use, the material is transported and dried by a conveyor belt, and the hot air is blown from top to bottom, so that the lower layer of material cannot fully contact the hot air, which affects the drying effect.

[0004] Another example is a high-efficiency material drying device with publication number CN116625088A. It is provided with a high-efficiency drying device on the basis of the original one-stage dewatering screw machine. It utilizes the hot air generated by the fan and heater or heat exchanger, and the turning of the granular activated carbon by each rake tooth to efficiently dry the granular activated carbon, thereby effectively removing the pore water of the granular activated carbon. At the same time, it can also utilize a filter with an anti-clogging function to filter impurities in the hot air, thereby preventing the impurities in the hot air from affecting the activated carbon particles. However, when it is used, it is necessary to completely dry the liquid remaining on the surface of the material, and it is impossible to remove the moisture on the surface of the material, resulting in a large heating energy consumption.

[0005] Another example is a material drying device with publication number CN106017018A, which uses hot air drying as the main method and infrared heating drying as the auxiliary method for drying. It has the advantages of high thermal efficiency, significant energy saving effect, fast drying efficiency, good drying quality, good safety, and environmental protection. In addition, the present invention is internally equipped with an ultraviolet sterilization lamp, which can sterilize the material to ensure high cleanliness. However, when stirring the material, it only uses axial stirring, so that the lower layer of material cannot be turned over to the upper layer, which will affect the heat drying of the lower layer of material, and there are certain usage defects. Summary of the Invention

[0006] The purpose of the present invention is to provide a material drying device and a drying method thereof to solve the problems raised in the above background technology that the material drying devices on the market are unable to effectively turn the materials to improve drying efficiency and are unable to remove excess moisture to reduce energy consumption.

[0007] To achieve the above-mentioned object, the present invention provides the following technical solution: a material drying device, comprising a tank body placed on the ground, an observation door installed on the tank body, a cover body fixedly installed on the upper end of the tank body, and a motor fixedly installed on the lower end of the tank body, and a heating pipe fixedly installed on the inner wall of the lower end of the tank body for heating and drying the material, a drive shaft fixedly installed on the output end of the motor, and a movable column installed on the outer side of the drive shaft, and a fixed seat sleeved on the outer side of the movable column, and a gas transmission component fixedly connected between the fixed seat and the inner wall of the lower end of the tank body;

[0008] The upper end of the movable column is fixedly connected to the central column, and the outer side of the central column is fixedly installed with a material tray in layers, and the lower surface of the material tray in the lower layer is fixedly installed with a guide rail. The inner side of the material tray is provided with a movable plate for lifting, and the upper surface of the movable plate is rotatably installed with two groups of kneading components for turning and kneading the material to improve the drying efficiency. The lower surface of the material tray is fixedly installed with a guide plate for diverting the water body.

[0009] The inner and outer walls of the tank body are respectively fixedly mounted with a drainage trough and a collection trough for realizing the centralized discharge and collection of water to accelerate the drying efficiency.

[0010] Preferably, the movable column and the drive shaft are key-connected, and the movable column and the drive shaft constitute a lifting structure, and the outer wall of the movable column is embedded with a first ball, and the inner wall of the middle cylindrical part of the fixed seat is provided with an elliptical annular guide groove, and the first ball and the guide groove are slidably connected.

[0011] By adopting the above technical solution, when the motor drives the drive shaft to rotate, the drive shaft can drive the movable column to rotate synchronously, so that the first ball on the outer wall of the movable column slides along the guide groove, thereby driving the movable column to perform reciprocating lifting and lowering adjustment during the rotation process.

[0012] Preferably, the material tray and the central column are coaxially arranged, the material tray is cylindrical, and filter holes are evenly opened on the material tray.

[0013] By adopting the above technical solution, the movable column can drive the material tray to rise and fall and rotate synchronously through the central column, so that the material in the material tray can be dried under the action of centrifugal force, thereby improving the subsequent drying effect.

[0014] Preferably, the gas delivery assembly includes a piston cylinder fixedly installed between the fixed seat and the tank body, and a piston plate is interference-mounted on the inner side of the piston cylinder, and a piston rod is fixedly installed on the upper end of the piston plate. At the same time, the upper end of the piston rod is arranged in a spherical structure, and the upper end of the piston rod is slidably connected to the guide rail to prevent the upper end of the piston rod from slipping off the guide rail.

[0015] By adopting the above technical solution, when the lower material tray is adjusted to rise or fall, the guide rail can pull the piston rod to move upward synchronously, so that the piston rod can drive the piston plate to rise and fall back and forth inside the piston cylinder.

[0016] Preferably, the lower end of the piston cylinder is connected to an intake pipe and an exhaust pipe respectively, and the intake pipe and the exhaust pipe are one-way flow structures with opposite flow directions, and the lower end of the intake pipe faces the motor, while the upper end of the exhaust pipe passes through the lower end of the tank body and faces the material tray.

[0017] By adopting the above technical solution, the piston cylinder can extract the air near the motor and blow it to the material tray through the exhaust pipe, which accelerates the drying efficiency and also cools the motor while recovering heat.

[0018] Preferably, filter holes are evenly opened on the movable plate, and the movable plate is sleeved on the outside of the central column, and a spring is sleeved on the outside of the central column. At the same time, the movable plate forms an elastic lifting structure through the spring and the material tray.

[0019] By adopting the above technical solution, the movable plate can be elastically raised and lowered under the elastic force of the spring, thereby improving the throwing and turning effects of the materials.

[0020] Preferably, a first magnetic block with an annular structure is fixedly installed on the lower surface of the movable plate, and a second magnetic block with an annular structure is fixedly installed on the upper surface of the drainage groove, and the positions of the first magnetic block and the second magnetic block are arranged correspondingly up and down, and the magnetic poles of the opposite surfaces of the first magnetic block and the second magnetic block are opposite.

[0021] By adopting the above technical solution, when the material tray is close to the drainage trough, the movable plate will move downward under the magnetic force of the first magnetic block and the second magnetic block, thereby compressing the spring. When the material tray moves upward, the magnetic force acting on the movable plate is reduced, so that the flipping effect of the material is further improved under the elastic force of the spring.

[0022] Preferably, a column is evenly fixed on the inner side of the lower end of the material tray, and a spiral groove is opened on the outer side of the column, and the column passes through the movable plate. The kneading component includes a sleeve rotatably installed on the movable plate, and a second ball is embedded in the inner wall of the sleeve, and the second ball is slidably connected along the groove.

[0023] By adopting the above technical solution, when the movable plate moves up and down, the sleeve can be driven to move up and down synchronously, so that the second ball slides along the slide groove, and then drives the sleeve to rotate back and forth.

[0024] Preferably, an arc-shaped washboard is fixedly installed on the outside of the sleeve, and the rotation directions of the inner and outer sets of sleeves are opposite, and the positions of the washboards on the outer sides of the two sets of sleeves are correspondingly arranged. At the same time, a cavity is opened on the surface of the washboard, and liquid-absorbing cotton is embedded and fixedly installed in the cavity, and a water suction pipe is connected between the cavity and the upper end of the sleeve. At the same time, a piston block is interference fit on the inner side of the sleeve, and the piston block and the top of the column are fixedly connected. A drainage pipe is installed through the piston block and the column, and the water suction pipe and the drainage pipe are one-way flow structures with opposite flow directions, and the lower end of the drainage pipe drains water toward the guide plate.

[0025] By adopting the above technical solution, when the two sets of scrubbing plates rotate, the material in the material tray can be effectively turned and kneaded, thereby improving the heating uniformity of the material. At the same time, the absorbent cotton can absorb moisture on the surface of the material it contacts, and under the absorption action of the water absorption pipe, the water is drawn into the inner side of the sleeve and discharged through the drain pipe, so that this part of the water does not need to be heated and evaporated, thereby improving the drying efficiency.

[0026] Another technical solution provided by the present invention is to provide a drying method for a material drying device, comprising the following steps:

[0027] The first step is to open the observation door when the material needs to be dried, and place the materials on the two layers of material trays respectively. Then, the observation door is closed, and the heating tube and the motor are turned on at the same time, so that the motor drives the driving shaft and the movable column to rotate synchronously. At the same time, the first ball on the outer side of the movable column slides along the guide groove on the inner wall of the fixed seat, so that the movable column is synchronously lifted and lowered during the rotation process, thereby driving the material tray to rotate and lift synchronously through the center column, so that the material tray can flip the material. At the same time, when the material tray is lifted and lowered, the first magnetic block and the second magnetic block under the movable plate can be intermittently attracted, so that the movable plate is elastically lifted and lowered synchronously when the material tray moves up, thereby further improving the flipping effect of the material and making the material heated more evenly.

[0028] In the second step, as the material tray moves up and down, the guide rail on its lower surface will drive the piston rod to move up and down synchronously, so that the piston rod pulls the piston plate to move back and forth inside the piston cylinder, so that the piston cylinder can extract the hot air near the motor through the suction pipe and blow it to the material tray through the exhaust pipe, thereby improving the air flow inside the tank and further promoting the drying effect;

[0029] Step 3: As the movable plate elastically rises and falls back and forth, the sleeve can be adjusted up and down on the outside of the column. At this time, the second ball on the inner wall of the sleeve will slide along the slide groove, causing the sleeve to rotate automatically, so that the washboards on the outside of the two sets of sleeves can turn and rub the material, allowing the absorbent cotton to absorb moisture from the surface of the material;

[0030] Step 4. As the sleeve rises and falls, the column will drive the piston block to rise and fall inside the sleeve, so that the sleeve can extract moisture from the absorbent cotton through the suction pipe, and discharge it to the guide plate through the drainage pipe, and then flow through the drainage trough one by one and flow into the collection tank, thereby avoiding heat absorption of this part of the water body, reducing heat loss, and achieving environmental protection and energy saving.

[0031] Compared with the prior art, the beneficial effects of the present invention are: the material drying device can effectively turn the material over so that the material is heated evenly, and can knead the material to absorb moisture, thereby reducing the heat energy required for drying. The specific contents are as follows;

[0032] 1. It is equipped with a motor, a movable column, a piston cylinder and a fixed seat. By starting the motor, the movable column can be driven to rotate synchronously. At the same time, the movable column will be telescopically adjusted with the drive shaft under the action of the first ball, so that the guide rail under the material tray pulls the piston rod to move back and forth, so that the piston cylinder can extract and recycle the hot air near the motor and blow it to the material tray, thereby accelerating the air flow inside the tank and effectively providing a drying effect;

[0033] 2. A material tray and a movable plate are provided. As the material tray moves up and down, it will drive the inner movable plate to move up and down synchronously. When the movable plate is close to the drainage trough, the first magnetic block and the second magnetic block on the two will produce a magnetic attraction, causing the movable plate to move down and compress the spring. When the material tray moves up to throw the material, the movable plate will elastically move up under the action of the spring force, thereby achieving further flipping of the material, effectively improving the uniform heating of the material;

[0034] 3. It is equipped with a column, a sleeve, a rubbing board and liquid-absorbing cotton. As the movable plate is raised and lowered, the sleeve on it will synchronously extend and retract along the column, so that the sleeve rotates under the action of the second ball, so that the rubbing board can turn the material, and the two sets of rubbing boards will rub the material during the rotation process, so that the liquid-absorbing cotton can absorb the moisture, and the sleeve can discharge the absorbed moisture at the same time to reduce the heat energy required for drying the equipment.

[0044] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0045] See also Figures 1-8 The present invention provides a technical solution: a material drying device, comprising a tank body 1 placed on the ground, an observation door 2 installed on the tank body 1, a cover body 3 fixedly installed on the upper end of the tank body 1, and a motor 4 fixedly installed on the lower end inner wall of the tank body 1, and a heating pipe fixedly installed on the lower end inner wall of the tank body 1 for heating and drying the material, a driving shaft 5 fixedly installed on the output end of the motor 4, and a movable column 6 installed on the outer side of the driving shaft 5, and a fixed seat 9 is sleeved on the outer side of the movable column 6, and a gas transmission component is fixedly connected between the fixed seat 9 and the inner wall of the lower end of the tank body 1;

[0046] The upper end of the movable column 6 is fixedly connected to the central column 11, and the outer side of the central column 11 is fixedly installed with a material tray 12 in layers, and the lower surface of the material tray 12 in the lower layer is fixedly installed with a guide rail 13. The inner side of the material tray 12 is provided with a movable plate 18 for lifting, and the upper surface of the movable plate 18 is rotatably installed with two sets of kneading components for turning and kneading the material to improve the drying efficiency. The lower surface of the material tray 12 is fixedly installed with a guide plate 31 for diverting the water body.

[0047] The gas delivery assembly includes a piston cylinder 8 fixedly mounted between a fixing seat 9 and the tank body 1. A piston plate 15 is interference fit inside the piston cylinder 8, and a piston rod 14 is fixedly mounted on the upper end of the piston plate 15. The upper end of the piston rod 14 is spherical and slidably connected to the guide rail 13 to prevent the upper end of the piston rod 14 from slipping off the guide rail 13. The lower end of the piston cylinder 8 is respectively connected to an intake pipe 16 and an exhaust pipe 17. The intake pipe 16 and the exhaust pipe 17 are unidirectional flow structures with opposite flow directions. The lower end of the intake pipe 16 faces the motor 4, while the upper end of the exhaust pipe 17 passes through the lower end of the tank body 1 and faces the material tray 12.

[0048] like Figures 1-4 As shown, when the materials are placed, the motor 4 is started, so that the motor 4 drives the movable column 6 to rotate synchronously through the drive shaft 5. At this time, the first ball 7 on the outer side of the movable column 6 will slide along the guide groove 10 on the inner wall of the fixed seat 9, and drive the movable column 6 to rise and fall synchronously. At this time, the movable column 6 will drive the material tray 12 to rise and fall synchronously through the center column 11, so that the guide rail 13 on the lower surface of the lower material tray 12 will pull the piston rod 14 to rise and fall synchronously, so that the piston piece 15 slides back and forth on the inner side of the piston cylinder 8. At this time, the piston cylinder 8 can extract and recover the hot air near the motor 4 through the suction pipe 16, and discharge it to the material tray 12 through the exhaust pipe 17, thereby accelerating the flow of air inside the tank body 1 and improving the drying effect.

[0049] The movable column 6 and the drive shaft 5 are keyed together, forming a lifting structure. A first ball bearing 7 is embedded in the outer wall of the movable column 6. An elliptical annular guide groove 10 is provided on the inner wall of the intermediate cylindrical portion of the fixed seat 9. The first ball bearing 7 and the guide groove 10 are slidably connected. The material tray 12 and the center column 11 are coaxially arranged. The material tray 12 is cylindrical and has filter holes uniformly formed thereon. The movable plate 18 has filter holes uniformly formed thereon and is sleeved on the outer side of the center column 11. A spring 19 is sleeved on the outer side of the center column 11. The movable plate 18 and the material tray 12 form an elastic lifting structure through the spring 19. A first annular magnetic block 21 is fixedly mounted on the lower surface of the movable plate 18, and a second annular magnetic block 22 is fixedly mounted on the upper surface of the drainage groove 20. The first and second magnetic blocks 21 and 22 are positioned in a corresponding position, and the magnetic poles of the opposing surfaces of the first and second magnetic blocks 21 and 22 are opposite.

[0050] like Figure 2-Figure 6 As shown, as the material tray 12 moves up and down, the material inside it can be flipped over. At the same time, when the material tray 12 moves down, the movable plate 18 will gradually approach the drainage trough 20, so that the first magnetic block 21 and the second magnetic block 22 on the two are close to each other. At this time, the movable plate 18 will compress the spring 19 under the action of the magnetic force, and when the material tray 12 moves up to realize the flipping of the material, the movable plate 18 will be affected by the elastic force of the spring 19 and move upward elastically, thereby improving the flipping effect of the material and ensuring that the material is heated evenly and dried quickly.

[0051] A column 23 is evenly fixed on the inner side of the lower end of the material tray 12, and a spiral chute 24 is opened on the outer side of the column 23, and the column 23 passes through the movable plate 18. The kneading component includes a sleeve 25 rotatably mounted on the movable plate 18, and a second ball 26 is embedded in the inner wall of the sleeve 25, and the second ball 26 is slidably connected along the chute 24. A curved rubbing plate 27 is fixedly installed on the outside of the sleeve 25, and the rotation directions of the inner and outer groups of sleeves 25 are opposite, and the positions of the rubbing plates 27 on the outer sides of the two groups of sleeves 25 are correspondingly arranged. At the same time, a cavity is opened on the surface of the rubbing plate 27, and a liquid-absorbing cotton 28 is embedded and fixedly installed in the cavity, and a water suction pipe 29 is connected between the cavity and the upper end of the sleeve 25. At the same time, a piston block 2301 is interference fit on the inner side of the sleeve 25, and the piston block 2301 is fixedly connected to the top of the column 23. A drainage pipe 30 is installed through the piston block 2301 and the column 23, and the water suction pipe 29 and the drainage pipe 30 are unidirectional flow structures with opposite flow directions, and the lower end of the drainage pipe 30 drains water toward the guide plate 31. The inner and outer walls of the tank body 1 are respectively fixedly mounted with a drainage groove 20 and a collection groove 32, which are used to realize centralized discharge and collection of water to accelerate drying efficiency.

[0052] like Figure 3-Figure 8As shown, as the movable plate 18 moves up and down, the sleeve 25 on its upper surface will be raised and lowered and adjusted on the outside of the column 23, so that the second ball 26 on the inner wall of the sleeve 25 will slide along the slide groove 24, thereby driving the sleeve 25 to rotate, so that the rubbing plate 27 on the outside of the sleeve 25 can stir the material, and when the two sets of rubbing plates 27 are close to each other, the absorbent cotton 28 on the outside can be used to rub the material to achieve full moisture absorption, and when the sleeve 25 is raised and lowered, the piston block 2301 will be raised and lowered and slid on the inside of the sleeve 25, so that the sleeve 25 can extract the liquid absorbed by the absorbent cotton 28 through the water suction pipe 29, and discharge it to the guide plate 31 through the drainage pipe 30, and enter the drainage trough 20 along the guide plate 31, and finally discharge it to the collection tank 32, so that the collected water does not need to be heated and evaporated, thereby reducing the drying energy consumption of the equipment and being more environmentally friendly and energy-saving.

When the material needs to be dried, the observation door (2) is opened, and the materials are placed in the two layers of material trays (12) respectively. Then, the observation door (2) is closed, and the heating tube and the motor (4) are turned on at the same time, so that the motor (4) drives the driving shaft (5) and the movable column (6) to rotate synchronously. At the same time, the first ball (7) on the outer side of the movable column (6) slides along the guide groove (10) on the inner wall of the fixed seat (9), so that the movable column (6) is synchronously raised and lowered during the rotation process, thereby driving the material tray (12) to rotate and rise synchronously through the central column (11), so that the material tray (12) flips the material. At the same time, when the material tray (12) is raised and lowered, the first magnetic block (21) and the second magnetic block (22) below the movable plate (18) are intermittently attracted, so that the movable plate (18) is elastically raised and lowered synchronously when the material tray (12) moves up, thereby further improving the flipping effect of the material and making the material heated more evenly. S2. As the material tray (12) moves up and down, the guide rail (13) on its lower surface drives the piston rod (14) to perform synchronous lifting and lowering adjustments, so that the piston rod (14) pulls the piston plate (15) to perform reciprocating adjustments on the inner side of the piston cylinder (8), so that the piston cylinder (8) extracts hot air near the motor (4) through the suction pipe (16) and blows it toward the material tray (12) through the exhaust pipe (17), thereby improving the air flow inside the tank body (1) and further promoting the drying effect; S3, as the movable plate (18) elastically rises and falls back and forth, the sleeve (25) is adjusted to rise and fall on the outside of the column (23), and at this time, the second ball (26) on the inner wall of the sleeve (25) slides along the slide groove (24), causing the sleeve (25) to automatically rotate, thereby causing the rubbing plates (27) on the outside of the two sets of sleeves (25) to turn and rub the material, so that the absorbent cotton (28) absorbs moisture from the surface of the material; S4. As the sleeve (25) rises and falls, the column (23) drives the piston block (2301) to rise and fall inside the sleeve (25), so that the sleeve (25) extracts water from the absorbent cotton (28) through the water suction pipe (29), and discharges the water to the guide plate (31) through the drainage pipe (30), and flows through the drainage groove (20) one by one and then flows into the collection groove (32), thereby avoiding heat absorption of this part of the water body, reducing heat loss, and achieving environmental protection and energy saving.
