Technical Field

[0001] This utility model relates to the field of zinc oxide particle screening technology, specifically a zinc oxide particle screening device. Background Technology

[0002] Zinc oxide, as an important chemical raw material, has wide applications in many fields (such as rubber, cosmetics, and electronic devices). Zinc oxide particle screening refers to the process of sieving zinc oxide particles to meet different application requirements. Screening can be divided into multiple particle size ranges, and different screens or screening equipment are usually used to separate particles based on their size, shape, density, and other characteristics.

[0003] For example, a zinc oxide particle screening device, as disclosed in announcement number CN221733945U, relates to the technical field of particle screening devices. This zinc oxide particle screening device includes a support leg, with a furnace body fixedly connected through its center. A controller is fixedly connected to the top front surface of the support leg. An auxiliary diversion device is installed inside the furnace body. A discharge trough is formed on the side of the furnace body. A positioning block is fixedly connected to the bottom surface of the other end of a filter plate. A hinge rod is hinged to the bottom surface of the positioning block. An electric telescopic rod is hinged to the bottom surface of the hinge rod. A circular groove is formed on the surface of the electric telescopic rod, which is located on the inner wall of the furnace body. A second discharge trough is formed on the bottom surface of the furnace body. An auxiliary screening device is installed on the top surface of the furnace body. This zinc oxide particle screening device effectively assists in the diversion of particles during screening.

[0004] The aforementioned patent proposes that a linear motor can be used to drive the second filter plate to move up and down, while the screened material enters the first filter plate at the bottom of the furnace body. The material is then diverted in the first filter plate. However, during the use of the zinc oxide particle screening device, zinc oxide particles are prone to absorbing moisture during the zinc oxide production process. Zinc oxide absorbs moisture from the air, causing the particles to easily stick together, which affects the screening.

[0005] Therefore, we propose a zinc oxide particle screening device to solve the problems mentioned above. Utility Model Content

The zinc oxide particles after passing through the third screen plate 13 can enter the collection drawer 14 for collection. The surface of the collection drawer 14 is evenly provided with ventilation holes 141 for ventilation. A heating element 16 is installed on the inner bottom wall of the screening frame 1. The heating element 16 is used for heating and can dry the zinc oxide particles to prevent the zinc oxide from absorbing moisture and affecting its performance.

[0026] The inner wall of the screening frame 1 is also provided with a striking element 17, which is located below the first screen plate 11. The upper ends of the second screen plate 12 and the third screen plate 13 are provided with scraping elements 18, which are used to push the zinc oxide particles on the second screen plate 12 and the third screen plate 13 out of the screening frame 1.

[0027] The heating element 16 includes a heating cavity 161 formed on the bottom wall of the screening frame 1 and a mounting base 162 disposed in the heating cavity 161. A heating tube 163 for heating is disposed on the inner side of the mounting base 162. When the heating tube 163 is turned on, the heat generated can rise to the top of the screening frame 1 through the vent hole 141.

[0028] The striking element 17 includes a motor base 171 disposed on the inner wall of the screening frame 1 and a motor 172 disposed on one side of the motor base 171. The output end of the motor 172 is connected to a cam 173 via a shaft. When the motor 172 is started, it can drive the cam 173 to rotate. When the cam 173 rotates, it can strike the first screen plate 11 and generate vibration on the first screen plate 11. This can reduce the adhesion of zinc oxide particles, promote the flow of zinc oxide particles, and allow the zinc oxide particles to be discharged from the discharge port 19.

A motor 312 is installed on the side wall of the conveying cylinder 31. The output end of the motor 312 passes through the conveying cylinder 31 and is connected to a spiral conveying shaft 313. Zinc oxide particles can enter the conveying cylinder 31 from the feed pipe 32. When the motor 312 is started, it can drive the spiral conveying shaft 313 to rotate, which can drive the zinc oxide particles to be conveyed, so that the zinc oxide particles can enter the screening frame 1 from the discharge pipe 34.

[0031] In this embodiment: Zinc oxide particles can enter the conveying cylinder 31 through the feed pipe 32. The motor 312 is started, which drives the screw conveyor shaft 313 to rotate, which can carry the zinc oxide particles to be conveyed, so that the zinc oxide particles can enter the screening frame 1 through the discharge pipe 34, which can realize the automatic feeding of zinc oxide particles. At the same time, the heating tube 163 is started, which can generate heat. At this time, the heat can fill the screening frame 1, and then the zinc oxide particles can be screened by the first screen plate 11, the second screen plate 12, and the third screen plate 13, which can dry the zinc oxide particles and prevent them from sticking together and affecting the screening. At the same time, the side door 2 is opened and the motor 172 is started, which can drive the cam 173 to rotate.

When the zinc oxide particles pass through the screen plate 311, the small impurities in the zinc oxide particles can be discharged through the screen plate 311 and fall into the collection frame 4 for collection, which can achieve the purpose of removing impurities.

[0035] Working principle: When the motor 312 is started, it drives the screw conveyor shaft 313 to rotate, which can carry the zinc oxide particles to be conveyed.

At the same time, the heating tube 163 is started, which can generate heat. At this time, the heat can fill the screening frame 1. Then, the zinc oxide particles can be screened by the first screen plate 11, the second screen plate 12 and the third screen plate 13, thereby drying the zinc oxide particles. Open the side door 2 and start the motor 172, which can drive the cam 173 to rotate.
