Description

Shaker

technical field

The utility model relates to material screening equipment, in particular to a vibrating screen.

Background technique

The vibrating screen works by using the reciprocating vibration generated by the excitation of the eccentric wheel. The upper rotating weight of the vibrator causes the screen surface to produce plane circular vibration, while the lower rotating weight causes the screen surface to produce conical rotary vibration. Its vibration track is a complex space curve. The projection of the curve on the horizontal plane is a circle, while the projection on the vertical plane is an ellipse. The vibration amplitude can be changed by adjusting the excitation force of the upper and lower rotating weights. And adjusting the spatial phase angle of the upper and lower weights can change the curve shape of the motion track of the screen surface and change the motion track of the material on the screen surface. With high efficiency and light weight, it can meet the demand for dry material screening. This model is not suitable for materials with high moisture and adhesion. The vibration makes the materials adhere to the screen surface more tightly during operation, resulting in material congestion or forced shutdown.

The energy consumption of vibrating screens currently on the market is relatively high, especially under high-efficiency working conditions. In addition, the working noise and dust are heavy. The cleaning and maintenance of the equipment is inconvenient. The life of the screen is short and the production cost is high.

In view of the above defects, the purpose of this utility model is to provide a vibrating screen with simple structure, convenient operation, high material screening efficiency and low energy consumption.

In order to achieve the above object, the utility model adopts the following technical solutions:

The vibrating screen includes a support frame and a sieve tray installed on the support frame; wherein, the sieve tray includes an upper sieve tray and a lower sieve tray, and a screen is installed between the upper sieve tray and the lower sieve tray; on the upper sieve tray A sieve cover is installed, and the lower part of the upper sieve tray is provided with an upper outlet, and an insert plate is installed on the upper outlet, and the bottom of the lower sieve tray is opened with a lower outlet. The horizontally extending motor mounting plate is integrated, the vibration motor is fixedly mounted on the motor mounting plate, and the lower sieve tray is mounted on the support frame through a buffer component.

As an improvement of the vibrating screen of the present invention, the screen is fixedly installed between the upper sieve tray and the lower sieve tray through a clamp.

As another improvement of the vibrating screen of the present utility model, the buffer component is elastic rubber or spring.

As a further improvement of the vibrating screen of the utility model, the lower sieve tray is in the shape of a circular platform.

As a further improvement of the vibrating screen of the utility model, the clamp is in the shape of a ring, and the tightness is adjusted by bolts.

As can be seen from the above, the utility model has the following beneficial effects compared with the prior art:

The vibrating screen of the utility model changes the original double-motor structure, adopts a single horizontal motor, and has various adjustment forms for the running track of the material. The adaptability of the equipment is significantly increased, and the energy consumption is significantly reduced. By fixing a motor mounting plate extending horizontally outward on the outer wall of the bottom of the sieve tray, the vibrating motor can drive the sieve tray to vibrate while vibrating, so that the materials can be screened, and the screened materials can be directly discharged from the lower outlet. Discharge, large processing capacity. After the material screening is completed, the large-grained material can be discharged from the opening of the sieve tray, so that the entire material screening process becomes efficient and fast, and the sieve tray has a simple structure and is easy to operate. The vibrating screen is equipped with a circular closed screen cover to prevent dust from flying, reduce noise, and is quiet and environmentally friendly. The clamp structure makes the sieve plate and screen installation, disassembly and washing, and replacement quick and convenient.
