One side of the connecting rod is connected to a plurality of toggle rods, which can break up the zinc oxide powder or particles in the drying tube during the rotation of the drying tube to prevent the zinc oxide powder or particles from agglomerating and ensure the quality of the drying of the zinc oxide powder or particles. A feed pipe is provided above the shell, and the upper end of the feed pipe is connected to a first valve, which is convenient for injecting the zinc oxide powder or particles to be dried into the drying cylinder. After the injection is completed, the feed pipe is closed using the first valve to prevent the zinc oxide powder or particles from falling from the feed pipe. A discharge pipe is provided below the shell, and the end of the discharge pipe away from the shell is connected to a second valve, which can discharge the zinc oxide powder or particles in the drying cylinder from the drying cylinder after drying is completed. The two ends of the shell are respectively detachably connected to a first cover and a second cover, which is convenient for assembly and maintenance of the first cover, the second cover and the drying cylinder.

[0009] As a further configuration of the above scheme, through holes are provided inside the first cover and the second cover to facilitate the installation of the drying tube. An exhaust pipe is provided on one side of the second cover, and a third valve is provided at one end of the exhaust pipe to discharge moisture in the drying cylinder.

[0010] As a further arrangement of the above scheme, the drying tube passes through the interior of the two through holes, and a bearing is connected to the outer side of the end of the second connecting member away from the first cover to reduce the friction between the drying tube and the first bracket. The outer side of the bearing is connected to the first bracket, and the lower end of the first bracket is detachably connected to the base to provide a bearing for one end of the drying tube to ensure smooth rotation of the drying tube.

[0011] As a further arrangement of the above scheme, the third connecting member and the fourth connecting member are both rotatably connected to the drying tube, which facilitates the installation and maintenance of the above two connecting members. A second bracket is provided on the outside of the third connecting member, and an air supply pipe is connected to the inside of the third connecting member. A hot air blower is provided on the end of the air supply pipe away from the third connecting member. The outsides of the hot air blower and the air supply pipe are both connected to the second bracket, and the hot air blown out of the hot air blower can be sent into the drying tube through the air supply pipe.

[0013] As a further arrangement of the above scheme, the telescopic end of the telescopic rod is connected to a connecting plate, which is used to adjust the vertical height of the universal brake wheel. The lower ends of the connecting plate are detachably connected to the universal brake wheels, which is convenient for adjusting and fixing the position of the drying device.

[0014] As a further arrangement of the above scheme, the universal brake wheel passes through the inside of the reserved hole, which helps the universal brake wheel to pass through the reserved hole and contact the ground before use, and lifts up the components of the device except the universal brake wheel to adjust the position of the device. After the position is adjusted, the universal brake wheel is lifted upward from the reserved hole to restore the contact between the base and the ground, so that the drying device remains stable.

[0015] The third valve in the drying device for preparing zinc oxide is a solenoid valve. Before use, the controller is used to set the opening and closing frequency of the third valve so that it opens when the exhaust pipe rotates to the upper side to discharge moisture in the drying cylinder and release the pressure of the hot air on the drying cylinder. It is immediately closed to prevent zinc oxide powder or particles from being discharged from the drying cylinder from the exhaust pipe. The first valve is opened, and a sufficient amount of zinc oxide raw material to be dried is injected into the drying cylinder from the feed pipe. The first valve is then closed, and the connection between the two first limit rods and the second connecting column is disconnected in turn to release the fixation of the limit rod on the drying cylinder. The motor and the hot air blower are then started by the controller to drive the motor to rotate the drying tube through the flat belt. The drying tube drives the drying cylinder to rotate during the rotation of the drying tube. During the rotation of the drying tube and the drying cylinder, the zinc oxide powder or particles in the drying cylinder are moved in the drying cylinder as the vertical distance between the first cover and the second cover and the base changes. The hot air blower continuously slides in the middle, and the hot air blower continuously injects hot air into the drying tube and blows it onto the zinc oxide powder or particles in the drying cylinder through the air outlet to remove moisture in the zinc oxide powder or particles. During the rotation of the drying cylinder, the connecting rod and the toggle rod rotate synchronously with the drying cylinder to break up the zinc oxide powder or particles in the drying cylinder to ensure the quality of drying. After the zinc oxide is dried, turn off the motor and the hot air blower, restore the connection between the two limit rods and the second connecting column, and fix the drying cylinder. At this time, the mouth of the discharge pipe is facing the base, open the second valve, and after the zinc oxide powder or particles are discharged from the drying cylinder, close the second valve, use the controller to start the pulse valve, blow pulse high-pressure airflow into the drying tube multiple times to blow off the zinc oxide adhered to the air outlet, clean the air outlet, and then close the pulse valve. Repeat the above operation to carry out the drying process of the next batch of zinc oxide.

[0016] When the position needs to be adjusted, use the controller to simultaneously control the extension of the telescopic rods to push the universal brake wheel completely out of the reserved hole, close the telescopic rods, lift the base off the ground, and make the universal brake wheel support the components other than the universal brake wheel. Then, the position of the device can be adjusted by rotating the universal brake wheel.

[0017] The present invention has the following beneficial effects during practical application:

[0018] 1. The combination of multiple mounting slots, connecting rods and toggle rods in the drying cylinder of the device facilitates the installation and maintenance of the above components, and can break up the zinc oxide powder or particles during the rotation of the drying cylinder to prevent the zinc oxide powder or particles from accumulating into clumps, thereby ensuring the drying quality of the zinc oxide powder or particles. The detachable connection between the first cover and the second cover and the drying cylinder further facilitates the installation of the connecting rod and the toggle rod inside the drying cylinder. The combined use of the connecting ring and the limit rod can fix the drying cylinder during the injection and discharge of zinc oxide, thereby preventing the drying cylinder from shaking due to inertia and ensuring the efficiency of injection and discharge.

[0019] 2. The first connector and the second connector of the threaded connection of the drying pipe can connect the drying pipe and the drying cylinder together, so that the drying pipe can smoothly drive the drying cylinder to rotate during the rotation process. The use of the pulse mechanism can blow off the zinc oxide powder or particles stuck in the air outlet, simplifying the cleaning method of the drying pipe and improving the cleaning efficiency of the drying pipe.

[0020] 3. The snap connection between the card block and the card hole in the position adjustment mechanism allows the two position adjustment mechanisms to be placed at both ends of the base before use. The telescopic rod is used to push the universal brake wheel downward from the reserved hole to separate the base from the ground. The drying device is moved by the rotation of the universal brake wheel. When it moves to the appropriate position, the connection between the base and the ground is restored, and the position adjustment mechanism and the base are removed from both ends of the base, which can effectively save manpower and investment in handling equipment.

[0039] like Figure 1 、 Figure 7 and Figure 8 As shown, the third connecting member 41 and the fourth connecting member 51 are both rotatably connected to the drying duct 3, which facilitates the installation and maintenance of the above two connecting members. A second bracket 43 is provided on the outside of the third connecting member 41. The inside of the third connecting member 41 is connected to the air supply pipe 42. A hot air blower 44 is provided on the end of the air supply pipe 42 away from the third connecting member 41. The outsides of the hot air blower 44 and the air supply pipe 42 are both connected to the second bracket 43.

[0041] like Figure 1 and Figure 9 As shown, a fourth bracket 71 is provided on the outer side of the telescopic rod 72, and blocks 711 are provided at both ends below the fourth bracket 71. The blocks 711 are engaged with the card holes 12 to limit the position of the position adjustment mechanism 7, making it convenient for the position adjustment mechanism 7 to be connected to the base 1. The telescopic end of the telescopic rod 72 is connected with a connecting plate 73, which is used to adjust the vertical height of the universal brake wheel 74. The universal brake wheels 74 are detachably connected to both ends below the connecting plate 73, which is convenient for adjusting and fixing the position of the drying device.

[0042] like Figure 1 As shown, the universal brake wheel 74 passes through the inside of the reserved hole 11, which helps the universal brake wheel 74 to pass through the reserved hole 11 and contact the ground before use, and lifts up the components of the device except the universal brake wheel 74 to adjust the position of the device. After the position is adjusted, the universal brake wheel 74 is lifted upward from the reserved hole 11 to restore the contact between the base 1 and the ground, so that the drying device remains stable.

[0043] Before use, the drying device for preparing zinc oxide disclosed in this embodiment is placed at both ends of the base 1 by engaging the two blocking blocks 711 in the position adjustment mechanism 7 with the internal blocking holes 12 of the base 1. The controller 8 is used to simultaneously control the two telescopic rods 72 to extend downward, and the universal brake wheels 74 are completely pushed downward from the reserved holes 11. After that, the telescopic rods 72 are closed, so that the four universal brake wheels 74 provide support for the base 1 and the connecting components above it, and the drying device is pushed. After the drying device is moved to a suitable position by the rotation of the universal brake wheels 74, the brakes of the universal brake wheels 74 are stepped on, and the controller 8 is again used to simultaneously control the two telescopic rods 72 to slowly retract. Under the action of gravity, the base 1 and the components above it slowly move toward the ground until the base 1 restores its support for the drying device. After the universal brake wheels 74 are completely pulled out of the reserved holes 11, the telescopic rods 72 are closed, and the position adjustment mechanism 7 is removed from both ends of the base 1 and properly placed for subsequent use.

[0044] After the position is adjusted, the controller 8 is used to set the opening and closing frequency of the third valve 262 so that the exhaust pipe 261 opens when it rotates to the upper side to discharge the moisture in the drying cylinder 2 and release the pressure of the hot air on the drying cylinder 2, and then closes immediately to prevent the zinc oxide powder or particles from being discharged from the drying cylinder 2 from the exhaust pipe 261. The first valve 231 is opened, and a sufficient amount of zinc oxide powder or particles to be dried is injected into the drying cylinder 2 from the feed pipe 23, and then the first valve 231 is closed. The two limit rods 28 are removed from both sides of the second mounting block 271, and the connection between the limit rods 28 and the first connecting column 131 and the second connecting column 2711 is disconnected to release the fixation of the limit rods 28 on the drying cylinder 2. Then, the controller 8 is used to start the motor 61 and the hot air blower 44, so that the motor 61 drives the drying tube 3 to rotate through the flat belt 63. During the rotation of the drying tube 3, the drying cylinder 2 is driven to rotate. During the rotation of the drying tube 3 and the drying cylinder 2, the zinc oxide powder or particles in the drying cylinder 2 slide in the drying cylinder 2 as the heights of the two ends of the drying cylinder 2 change alternately. When the zinc oxide When the powder or particles come into contact with the toggle rod 221, the clumped zinc oxide powder or particles are broken up. At the same time, the hot air blower 44 continuously injects hot air into the drying tube 3 and blows it onto the zinc oxide powder or particles in the drying cylinder 2 through the air outlet 31, so as to remove moisture from the zinc oxide powder or particles to ensure the quality of drying. After the zinc oxide is dried, the motor 61 and the hot air blower 44 are turned off, and the connection between the two limit rods 28 and the first connecting column 131 and the second connecting column 2711 is restored to fix the drying cylinder 2. At this time, the mouth of the discharge pipe 24 is facing the base 1, the second valve 241 is opened, and the zinc oxide powder or particles are discharged from the drying cylinder 2. After the zinc oxide powder or particles are completely discharged, the second valve 241 is closed, and the controller 8 is used to start the pulse valve 52 to blow pulsed high-pressure air into the drying tube 3 multiple times to blow off the zinc oxide powder or particles adhering to the air outlet 31 and clean the air outlet 31 to ensure the air outlet efficiency of the air outlet 31. Then the pulse valve 52 is closed and the above operation is repeated to carry out the drying process of the next batch of zinc oxide.

[0045] Since the driving mechanism of the telescopic rod 72 is conventional technology in this field, the schematic diagram here is only for indicating its installation position, and therefore, it is not drawn in the figure.

[0046] The above are only preferred embodiments of the present invention and are not intended to limit the invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the invention should be included in the scope of protection of the present invention.
