[0014] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.
[0015] Embodiment: As Figures 1-3As shown in the figure, the utility model provides a dryer for zinc oxide production, which includes an outer shell 1. A discharging device 2 is fixedly installed at the bottom end of the outer shell 1. The top end of the outer shell 1 is fixedly connected with a machine cover 10. One side of the top end of the machine cover 10 is fixedly connected with a feeding port 11, and the other side of the top end of the machine cover 10 is fixedly provided with an observation port 12. A sampling valve 15 is fixedly connected to the outer surface of the lower part of the outer shell 1. A drying mechanism 3 is arranged inside the outer shell 1. The drying mechanism 3 includes a stirring shaft 33. A stirring belt 34 is fixedly connected to the outer surface of the stirring shaft 33. The top end of the stirring shaft 33 is fixedly connected with a shaft sleeve 32. A shaft seal 31 is fixedly installed at the top end of the machine cover 10. A first motor 30 is fixedly provided at the top end of the shaft seal 31. The output end of the first motor 30 is fixedly sleeved with the inner wall of the shaft sleeve 32. The inner wall of the outer shell 1 is fixedly connected with an inner shell 35. A jacket 36 is fixedly installed between the inner wall of the outer shell 1 and the inner shell 35. Under the output of the first motor 30, the stirring shaft 33 and the stirring belt 34 rotate continuously, so as to cyclically rotate, lift and lower the materials inside the outer shell 1. Under the nitrogen delivery of the heat-conducting oil and nitrogen pipeline 13, the temperature of the materials is raised and the materials are dried, thereby realizing the drying and mixing and stirring of the materials.
[0016] The discharging device 2 includes a valve body 21. An inlet 22 is provided at the top end of the valve body 21, and a discharging port 23 is provided at the bottom end of the valve body 21. A second motor 24 is fixedly installed at one end of the valve body 21. The output end of the second motor 24 penetrates through the valve body 21 and is fixedly sleeved with a transmission shaft 25. One end of the transmission shaft 25 is rotatably connected to one end of the valve body 21. A plurality of blades 26 are fixedly connected to the outer surface of the transmission shaft 25. Driven by the output of the second motor 24, the transmission shaft 25 and the blades 26 rotate. The rotating blades 26 scrape the descending material from the inlet 22 to the discharging port 23. The material descends and is discharged from the discharging port 23 due to its own weight, realizing the quantitative discharging movement of the material. At the same time, it separates the air pressure between the upper and lower parts of the discharging device 2, playing a role in air locking. The outer shell 1 and the stirring belt 34 are both conical. The stirring belt 34 is spiral, and the height of the stirring belt 34 is the same as the height of the cavity of the outer shell 1. A nitrogen pipeline 13 is fixedly connected to the top end of the machine cover 10. The nitrogen pipeline 13 penetrates into the outer shell 1. There is heat-conducting oil between the jackets 36. A plurality of fixing bolts are fixedly installed on the outer surface of the machine cover 10, and the plurality of fixing bolts are distributed in a circular array. The purpose of the conical outer shell 1 is to increase the internal volume of the outer shell 1 and reduce the floor area of the equipment. The conical spiral stirring belt 34 is to make the material rotate continuously during the stirring process. Due to the different slopes of the cone and the rotation speed, the material will undergo multiple up-and-down alternating movements, facilitating the up-and-down tumbling of the material. The nitrogen pipeline 13 penetrating into the interior of the outer shell 1, under the transportation of nitrogen, enables the material with increased temperature to evaporate moisture while effectively degrading and drying the moisture, playing a certain drying role. The role of the heat-conducting oil is to facilitate the heat-conducting oil for heating to transfer heat to the material in the cavity through the inner shell 35. There are five plurality of blades 26, and the plurality of blades 26 are distributed in a circular array. The length of the blades 26 is the same as the inner diameter of the valve body 21, and the outer surface of the blades 26 is slidably attached to the inner wall of the valve body 21. The five blades 26 distributed in a circular array transport the material from the inlet 22 to the discharging port 23, realizing the continuous and uniform discharge of the material, preventing the material from being blocked and caked during the transportation process. The blades 26 attached to the inner wall of the valve body 21 are to ensure the airtightness inside the valve body 21, thereby ensuring the stability of the air pressure inside the valve body 21 and making the transportation more stable.
[0017] Working principle: When zinc oxide needs to be dried, the zinc oxide enters the outer shell 1 through the feeding port 11. Then, the first motor 30 in the drying mechanism 3 is started. The output end of the first motor 30 drives the stirring shaft 33 to rotate through the shaft sleeve 32. The rotating stirring shaft 33 drives the stirring belt 34 to rotate vertically. The threaded stirring belt 34 rotates and lifts the zinc oxide. At the same time, heat-conducting oil is introduced into the jacket 36. Under the heat transfer of the inner shell 35, the temperature in the cavity of the outer shell 1 rises, resulting in the heating of the zinc oxide inside the cavity. Nitrogen is transported into the outer shell 1 from the nitrogen pipeline 13 to reduce the moisture in the outer shell 1. The continuous cyclic rotation of the stirring belt 34 causes the zinc oxide to be lifted from all around and fall from the middle, achieving the purpose of drying and mixing the zinc oxide. The operator can observe the materials in the outer shell 1 through the observation port 12 and take samples of the materials for analysis through the sampling valve 15 at the bottom; When discharging is required, the dried zinc oxide enters the valve body 21 through the feeding port 22. The second motor 24 is started. The output end of the second motor 24 drives the transmission shaft 25 to rotate. The rotating transmission shaft 25 drives the blades 26 to rotate inside the valve body 21. The rotating blades 26 continuously agitate the descending zinc oxide, so that the zinc oxide is discharged from the discharge port 23 at the bottom of the valve body 21 by its own weight during the agitation process, thus achieving the purpose of quantitative and continuous discharging.
[0018] Obviously, those skilled in the art can make various changes and modifications to the present utility model without departing from the spirit and scope of the present utility model. Thus, if these modifications and variations of the present utility model fall within the scope of the claims of the present utility model and their equivalent technologies, the present utility model also intends to include these changes and modifications.
