Description

Vibrating screen

Technical Field

The utility model relates to a shale shaker especially relates to a shale shaker.

Background

The multi-layer vibrating screen is suitable for devices for separating solid particles with different sizes. The vibrating screen accelerates the separation speed by using a vibrating screen mesh mode. But vibration can cause solid particles to splash. In the prior art, splashed particles are collected by using a shell, but the splashed particles still need to be separated again. In the other mode in the prior art, the mode of mutually overlapping multiple layers of screens can increase the overall weight of the screens, and the vibration effect can be achieved by inputting more power.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that overcome exist among the prior art not enough, provide a shale shaker, can reduce the vibration in-process and produce the granule and splash.

The utility model discloses a realize through following technical scheme:

the utility model provides a vibrating screen, includes motor, pendulum, screen cloth and shell, the output shaft cam of motor, the motor periphery is around a plurality of pendulums, the maximum diameter department contact pendulum of cam is a plurality of mounting bracket is connected to the pendulum, and is a plurality of the mounting bracket from the top down arranges in proper order, mounting bracket fixed connection screen cloth, and is a plurality of the screen cloth is arranged from the top down according to the order from big to little of mesh number, the screen cloth is equipped with the protection casing, every the upper portion mouth of the protection casing of screen cloth all is located above the adjacent screen cloth of top along the department, the shell is cylindric, the equal fixed connection shell bottom of motor and pendulum, the sieve lid is connected to the opening part of shell, the sieve lid is equipped with the guard ring, the guard ring is located the superiors screen cloth outside and is located under.

According to the above technical solution, preferably, the vibrating body includes a metal tube, a support and a buffer layer, one end of the metal tube is fixedly installed at the bottom of the housing, the metal tube covers the buffer layer, the maximum diameter of the cam contacts the buffer layer, the metal tube is provided with a plurality of supports, and the supports are connected to the mounting frame through springs.

The utility model has the advantages that: the screen cloth is equipped with the protection casing, and the upper end of the protection casing of every screen cloth all is located above the adjacent screen cloth for form airtight space between the adjacent screen cloth, even have the gap between protection casing and the above screen cloth, the possibility that the granule splashes also can greatly reduced. The splashing of particles is reduced by the above structure. And the vibrating body is equipped with the shell outward, and the shell top opening is equipped with the screen cover, and the guard ring of screen cover is located the superiors screen cloth outside and is located the superiors screen cloth opening below, can prevent that the superiors screen cloth from taking place to splash.

Drawings

Fig. 1 shows a schematic front view structure diagram of an embodiment of the present invention.

In the figure: 1. the vibrating screen comprises a motor, a vibrating body 2, a screen 3, a shell 4, a cam 5, a mounting frame 6, a protective cover 7, a screen cover 8, a protective ring 9, a metal pipe 10, a support 11 and a buffer layer 12.

Detailed Description

In order to make those skilled in the art better understand the technical solution of the present invention, the present invention will be further described in detail with reference to the accompanying drawings and preferred embodiments.

As shown in the figure, the utility model relates to a vibrating screen, which comprises a motor 1, a vibrating body 2, a screen 3 and a shell 4, the output shaft of the motor is connected with a cam 5, the motor externally surrounds a plurality of vibrators, the maximum diameter position of the cam is contacted with the vibrators, the vibrators are connected with a plurality of mounting frames 6, the mounting frames are sequentially arranged from top to bottom, the mounting frame is fixedly connected with the screen meshes, the screen meshes are arranged from top to bottom in the order of the mesh number from large to small, the screens are provided with protective covers 7, the upper opening edge of each protective cover of each screen is positioned above the adjacent screen, the shell is cylindrical, the motor and the vibrating body are fixedly connected with the bottom of the shell, the opening of the shell is connected with the screen cover 8, the screen cover is provided with a protective ring 9, and the protective ring is positioned on the outer side of the uppermost screen and below the opening of the uppermost screen.

In this embodiment, the motor drives the cam to rotate, and the cam can collide with the vibrating body in the rotating process to enable the vibrating body to vibrate. The screen cloth is connected through the mounting bracket to the pendulum, and the vibration of pendulum also can transmit the screen cloth in, and the solid particle on the screen cloth receives the vibration for the screening separation.

The screen cloth is equipped with the protection casing, and the upper end of the protection casing of every screen cloth all is located above the adjacent screen cloth for form airtight space between the adjacent screen cloth, even have the gap between protection casing and the above screen cloth, the possibility that the granule splashes also can greatly reduced. The splashing of particles is reduced by the above structure.

And the vibrating body is equipped with the shell outward, and the shell top opening is equipped with the screen cover, and the guard ring of screen cover is located the superiors screen cloth outside and is located the superiors screen cloth opening below, can prevent that the superiors screen cloth from taking place to splash.

According to the above technical solution, preferably, the vibrating body includes a metal tube 10, a bracket 11 and a buffer layer 12, one end of the metal tube is fixedly installed at the bottom of the housing, the metal tube covers the buffer layer, the maximum diameter of the cam contacts the buffer layer, the metal tube is provided with a plurality of brackets, and the brackets are connected with the mounting frame through springs.

In the present embodiment, a structure of a vibrating body is disclosed.
