Description

Technical Field

[0001] The utility model relates to the technical field of mica processing, in particular to a vibration screening device for synthetic mica. Background Art

[0002] Synthetic mica is also called fluorophlogopite. It is a typical layered silicate made from chemical raw materials through high-temperature melting, cooling and crystallization. It has many properties superior to natural mica, such as high temperature resistance, good electrical insulation, extremely low vacuum outgassing at high temperature, acid and alkali resistance, transparency, strippability and elasticity. It is an important non-metallic insulating material for modern industries and high technologies such as motors, electrical appliances, electronics and aviation. In the production and processing of synthetic mica, in order to meet the particle size requirements of synthetic mica in different industries and application fields, it is necessary to screen the synthetic mica raw materials through screening and processing equipment.

The patent can drive the screening plate to vibrate while the screening operation is in progress, so that some of the mica powder blocked in the screening plate can be shaken out. At the same time, the device does not require additional power source when in use, and is more environmentally friendly.

[0034] The beneficial effects of the above embodiments are:

[0035] 1. The synthetic mica vibration screening device can screen mica powder by using a sieve drum structure with different sieve hole sizes through a screening and processing mechanism, which can not only realize the graded screening of mica powder, so that the screened mica powder can be applied to different industries and fields, and the practical effect of the device is enhanced, but also can cooperate with the rotation of the sieve drum structure, so that the mica powder entering the sieve holes inside the sieve drum can automatically separate from the sieve holes under the action of gravity when it is at the highest point of the sieve drum, thereby effectively reducing the risk of the sieve holes inside the sieve drum being blocked, enhancing the anti-blocking effect of the sieve drum, prolonging the service life of the sieve drum, and enhancing the practicality of the device.

[0036] 2. The vibration screening device for synthetic mica can utilize the rotation of the eccentric wheel 23 to push the limit rod 19 to slide in the guide sleeve 20 through the vibration auxiliary component, so that the movable plate 2 drives the screening structure to vibrate, so as to shake out the mica powder that causes the sieve holes in the sieve cylinder to be blocked, further improve the anti-blocking effect of the sieve cylinder, and enhance the practical effect of the device.

[0037] The working principle of the above embodiment is:

[0038] When the synthetic mica vibrating screening device is used, the first screen drum 8, the second screen drum 9 and the third screen drum 10 need to be placed on the driving baffle plate 5 by using the limiting sleeve 11, and then the rotating baffle plate 7 is pushed against the other end of the screen drum structure by pushing the movable mounting plate 4, and then the positioning plate 14 can be fixedly installed on the movable plate 2 by using the positioning bolts, so as to limit the movement of the movable mounting plate 4, and then keep the installation of the screen drum structure stable;

[0039] After that, the position of the movable plate 2 can be adjusted to move the screening structure into the box body 1, and the upper limit rod 19 on the movable plate 2 can pass through the guide sleeve 20. Then, the mica powder to be screened can be added to the first screen cylinder 8 through the provided feed pipe 6. At the same time, the rotating motor 17 can be operated so that the driving baffle 5 drives the screening structure to rotate under the action of the gear transmission structure, thereby realizing the graded screening of the mica powder.

[0040] In this process, not only will the mica powder not contact a certain part of the screen drum for a long time, but the mica powder that has entered the screen holes inside the screen drum can also automatically leave the screen holes under the action of gravity when it is at the highest point of the screen drum, so as to effectively reduce the risk of the screen holes inside the screen drum being blocked. In addition, the eccentric wheel 23 can be driven to rotate by operating the driving motor 22, so that the rotation of the eccentric wheel 23 can be used to push the limit rod 19 to slide in the guide sleeve 20, so that the movable plate 2 drives the screening structure to vibrate, thereby shaking out the mica powder that causes the screen holes in the screen drum to be blocked, and further improving the anti-blocking effect of the screen drum.

[0041] The mica powder with the smallest particle size can fall after multi-stage screening, so that the collecting frame 12 can collect the mica powder with the smallest particle size. In addition, when the device is not in use, the movable plate 2 and the screening structure in the box body 1 can be lifted by the provided lifting handle, and the movable mounting plate 4 can be removed to move the rotating baffle 7, thereby facilitating the removal of the mica powder inside the first sieve drum 8, between the first sieve drum 8 and the second sieve drum 9, and between the second sieve drum 9 and the third sieve drum 10.
