The feeding port communicated with the screen cylinder is provided with a discharge port which is communicated with the screen cylinder at the end of the discharging end of the box body. When working, the material to be dehydrated enters the screen cylinder from the feeding port, the rotating main shaft rotates under the drive of the driving device, and the spiral blade on the rotating main shaft drives the material to rotate in the screen cylinder while continuously conveying it to the discharge port. , Under the action of centrifugal force, the water on the material is continuously discharged into the box from the mesh on the screen cylinder, the water in the box is discharged from the drainage port at the bottom, and the dehydrated material is discharged from the discharge port at the end. The feeding port of this plastic slice dehydration device is directly opened on the box on the top of the screen cylinder. When the rotating spindle rotates at a high speed, the material is easy to splash out from the feeding port, thus affecting the feeding amount and feeding. Moreover, after the material enters the screen cylinder, from the feed end to the discharge end, the material always bears the same centrifugal force, which cannot achieve the best dehydration effect within the limited dehydration time.

SUMMARY OF THE INVENTION

In view of the above deficiencies, the present utility model provides a vertical stepping centrifugal device.

It can feed smoothly, with high dehydration efficiency, and can generate step-by-step centrifugal force.

The technical scheme adopted by the utility model is:

A vertical stepping centrifugal device includes a bottom frame, a conical shell is arranged on the bottom frame, a water outlet is arranged at the bottom of the conical casing, a feed port is arranged under the left side of the conical casing, and the conical casing is provided with a water outlet. A discharge port is arranged on the upper right side of the shell, and a cyclone separator is installed at the discharge port. A sieve cylinder made of a mesh plate used in conjunction with the conical shell is set in the conical casing, and a sieve cylinder is arranged through the sieve cylinder. The vertical main shaft is movably supported in the bearing seat on the conical shell, and the lower end of the vertical main shaft is connected with a driving device capable of driving the main shaft to rotate.

A further improvement scheme of the utility model is that a feeding device is installed at the feeding port of the conical shell.

A further improvement scheme of the utility model is that the structure of the feeding device is divided into a feeding cylinder which is communicated with the screen cylinder, a feeding hopper is arranged above the feeding cylinder, and a feeding screw is arranged in the feeding cylinder. , the feeding screw rotates under the drive of the feeding motor on the feeding cylinder to send the material into the sieve cylinder.

The further improvement scheme of the utility model is that the vertical main shaft in the sieve cylinder is in the shape of a cone, the vertical main shaft is provided with a dehydration blade used in cooperation with the sieve cylinder, and the dewatering blade and the vertical main shaft are inclined, which can remove the material. Convey to the outlet.

The beneficial effects of the present utility model are:

There is no splashing material, the feeding is smooth, the dehydration efficiency is high, and the moisture content of the dehydrated material is low.

Detailed ways:

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the implementations. example. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

As shown in the drawings, the vertical stepping centrifugal device includes: a base frame 1, a conical casing 2 is arranged on the base frame 1, a water outlet 3 is arranged at the bottom of the conical casing 2, A feed port 4 is provided on the lower left side, a discharge port 5 is provided on the upper right side of the conical shell 2, a cyclone separator 6 is installed at the discharge port 5, and the conical shell 2 is provided with a conical shell. The sieve cylinder 7 is made of a mesh plate used in conjunction with the body 2. A vertical main shaft 8 is arranged through the sieve cylinder 7, and the vertical main shaft 8 is movably supported in the bearing seat on the conical shell 2. The lower end of the vertical main shaft 8 A drive device 9 capable of driving the vertical spindle 8 to rotate is connected.
