Description

Technical Field

[0001] The utility model relates to the technical field of zinc oxide production, in particular to a dryer for zinc oxide production. Background Technique

[0002] Zinc oxide is an oxide of zinc, insoluble in water, soluble in acids and strong alkalis, and is a commonly used chemical additive, widely used in the production of plastics, silicate products, synthetic rubber, lubricating oil, paint coatings, ointments, flame retardants and other products. Zinc oxide has a large band gap and exciton binding energy, high transparency, and excellent room temperature luminescence performance, and is applied in products such as liquid crystal displays, thin film transistors, and light emitting diodes in the semiconductor field. During the production process of zinc oxide, a dryer is required for drying treatment. However, in the current dryer for zinc oxide, during use, zinc oxide is usually placed inside a large tank for drying treatment. Since zinc oxide is in powder form, the wet zinc oxide piled together is not easy to dry, thus affecting the drying efficiency of zinc oxide. Therefore, we propose a dryer for zinc oxide production to solve the above problems. Content of the Utility Model

[0022] Embodiment

[0023] As Figure 1 、 Figure 2 Figure 3As shown in the figure, a dryer for zinc oxide production proposed by an embodiment of the present utility model includes a bottom plate 1. A support frame 2 is fixed on the top of the bottom plate 1. Three through holes opened on the top of the support frame 2 are each internally fixed with a housing 3. A tank body 4 is fixed inside each housing 3. Two heating plates 5 are fixed on the outer walls of the tank bodies 4. A stirring paddle 6 is rotatably connected inside each tank body 4 through a bearing. Chain gears 9 are fixed on the surfaces of the stirring paddles 6. The three chain gears 9 are connected by a chain 10 in a transmission manner, so that under the action of one motor, the three stirring paddles 6 can be driven to rotate simultaneously, thus saving production costs. A diversion hopper 7 is arranged above the bottom plate 1. The bottom ends of the diversion hopper 7 are fixedly communicated with the feeding ports of the three tank bodies 4. A drying assembly 8 for secondary treatment of zinc oxide inside the tank body 4 is arranged on the top of the bottom plate 1. When using this dryer for zinc oxide production, after placing it in a suitable position, the wet zinc oxide can be sent into the inside of the diversion hopper 7. The diversion hopper 7 provided can divert it into the inside of the three tank bodies 4. The heating plates 5 fixed on the outer walls of the tank bodies 4 can heat the inside of the tank bodies 4. And with the cooperation of the stirring paddles 6, the zinc oxide inside can be dried. When it is discharged after drying, the dried zinc oxide powder will fall into the inside of the drying assembly 8 for re-drying operation, and at the same time of secondary drying, it can also be pulverized.

[0024] As Figure 1 , Figure 2 and Figure 4As shown, in some embodiments, the drying assembly 8 is fixed to the box body 801 on the top of the bottom plate 1 through a mounting frame. A diversion hopper 802 is fixedly connected and communicated at the top of the box body 801. The top ends of the diversion hoppers 802 are fixedly connected and communicated with the discharge ports of the three tanks 4. Two hollow rollers 803 are rotatably connected inside the box body 801 through bearings. Two scrapers 811 for cleaning the surfaces of the hollow rollers 803 are fixed inside the box body 801. After the hollow rollers 803 crush the dried zinc oxide, the zinc oxide powder adhered to their surfaces can be scraped off by the provided scrapers 811, avoiding affecting the crushing effect of the zinc oxide powder. A heating water tank 804 fixed to the top of the bottom plate 1 is arranged on one side of the box body 801. A hot water pump 805 is fixed to the top of the heating water tank 804. The inlet end pipe of the hot water pump 805 penetrates through the heating water tank 804 and extends into its interior. The outlet end pipe of the hot water pump 805 is fixedly connected and communicated with a water delivery pipe 806. Both ends of the water delivery pipe 806 are fixedly connected and communicated with the water inlet ends of the two hollow rollers 803. The water outlet ends of the hollow rollers 803 are fixedly connected and communicated with drain pipes 807. The bottom ends of the drain pipes 807 are fixedly connected and communicated with the top of the heating water tank 804. During use, when the hot water pump 805 is started, the hot water pump 805 can pump the hot water inside the heating water tank 804 through the water delivery pipe 806 into the interior of the hollow rollers 803. Then, the hot water flowing inside them will flow back into the heating water tank 804 again through the drain pipes 807. Thus, the two hollow rollers 803 can be heated under the action of the circulating hot water. When the dried zinc oxide powder inside the tank 4 enters the interior of the box body 801 through the diversion hopper 802, the two reversely rotating hollow rollers 803 can crush the zinc oxide powder. And during the crushing process, since the powder will contact the surface of the heated hollow rollers 803, secondary drying treatment of the zinc oxide powder can be achieved. And during use, three valves are installed on the diversion hopper 802 to facilitate the retention of the zinc oxide powder inside the tank 4 for drying treatment. And a heating pipe for heating the water inside it is installed inside the heating water tank 804, and neither of them is shown in the figure. Secondly, the water delivery pipe 806 and the drain pipes 807 are fixedly connected and communicated with the water inlet ends and the water outlet ends of the hollow rollers 803 through rotatable connecting joints, thus realizing water circulation while avoiding interfering with the rotation of the hollow rollers 803.

[0025] As Figure 2As shown, in some embodiments, two transmission shafts 808 are rotatably connected to one side wall of the box body 801 through bearings. Transmission gears 809 are fixed on the surfaces of the transmission shafts 808. The two transmission gears 809 are meshed with each other. Tooth rings 810 are fixed on the surfaces of the hollow rollers 803. The tooth rings 810 are respectively meshed with the corresponding transmission gears 809. During use, with the cooperation of the two transmission gears 809 and the two tooth rings 810, one motor can drive the two hollow rollers 803 to rotate in opposite directions simultaneously, thereby saving production costs.

[0026] As Figure 3 As shown, in some embodiments, cleaning frames 11 for cleaning the inner wall of the tank body 4 are fixed on the surfaces of the stirring paddles 6. When the dried zinc oxide powder inside the tank body 4 is discharged, the provided cleaning frames 11 can clean the inner wall of the tank body 4, thereby preventing it from adhering to the inner wall of the tank body 4.

[0027] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
