Description

Vibrating screens for feed production

technical field

The utility model relates to the technical field of feed production, in particular to a vibrating screen for feed production.

Background technique

The vibrating screen works by using the reciprocating rotation vibration generated by the vibration of the vibrator. 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.

Vibrating screens are mainly divided into linear vibrating screens, circular vibrating screens, and high-frequency vibrating screens. Vibrating screens can be divided into single-shaft vibrating screens and double-shaft vibrating screens according to the type of vibrator. The single-axis vibrating screen uses a single unbalanced weight to vibrate the screen box, the screen surface is inclined, and the motion track of the screen box is generally circular or elliptical. The double-axis vibrating screen is excited by double unbalanced weights that rotate in different directions synchronously. The screen surface is horizontal or gently inclined, and the motion track of the screen box is a straight line. Vibrating screens include inertial vibrating screens, eccentric vibrating screens, self-centering vibrating screens and electromagnetic vibrating screens.

A typical vibrating screen is shown in FIG. 1 , including a feed port 10 and a finished product bin 12 with a screen cover 11 , and the finished product bin 12 is mounted on a base 13 through elastic supports 14 and 15 . During work, for example, in the aquatic product processing technology, the material particles produced by the granulator enter the finished product bin 12, and enter the packaging scale after being screened by the vibrating screen. The main screening unit of the vibrating screen is the screen (not shown in Figure 1), which can be replaced according to the particle size of the material. For example, in order to sieve material particles of different sizes, the screen needs to be replaced, or sometimes the screen needs to be cleaned. At this time, the screen needs to be taken out from the finished product bin 12 .

In the prior art, the screen is taken out through the screen cover 11 of the finished product bin 12. Because the screen area is large, the screen cover also needs to have a larger opening. In addition, after the screen is installed, it needs to pass through a fixing mechanism, such as Fig. The bolts 111 in 1 fix the screen cover 11. This fixing structure is time-consuming and laborious, and requires a large operating space, which is very inconvenient to operate.

In addition, it can also be seen from Fig. 1 that, compared with the finished product bin 12, the area of the feed port 10 is relatively small, so that the materials entering from the feed port 10 are easy to accumulate in the partial area of the feed bin. had an impact.
