(54) DEVICE FOR PRESSING VISCOUS MATERIALS

I

The invention relates to mechanical engineering and can be used in the mixing and pressing of viscous materials used in various industries of the national economy, in particular a feed mill, industry.

A device for pressing viscous materials is known, containing, interconnected and forming a working chamber, a body, a stationary annular matrix with radial holes and a feed funnel, as well as a radial wheel mounted in the working chamber with annular grooves in its blades, a disk fixed to and the auger 1 located in the grooves in the grooves mentioned above and aligned with the radial wheel.

The disadvantage of such a device is an increased path of movement of the material being processed, partial or full blocking of the space between the screw and the races by the material, which leads to a decrease in the reliability of the device and the quality of the material being processed.

The purpose of the invention is to increase the reliability of the device and the quality of the processed material.

This goal is achieved by the fact that the device is equipped with a mixer mounted above the loading chamber, as well as two disks located between the mixer and the screw with radial grooves, while the screw is fixed on the disk and kinematically connected with the mixer.

The drawing shows the inventive device for pressing viscous materials.

The device comprises a housing 1, an annular matrix 2 with radial holes, a radial wheel 3, in the blades 4 of which there are concentrically arranged annular grooves, a drive shaft 5 on which the radial wheel 3 is fixed, a disk 6 with race grilles 7 that are in annular 20 grooves of the radial wheel 3, the screw 8, to which the disk 6 is fixedly attached. The screw shaft 9 rotates in the bearing 10 which by means of a radial blade current 11 is connected to the boot body

the funnels 12, a mixer 13 is installed above the funnel 12, the shaft 14 of which has blades 15 and is connected to the shaft 9 of the screw 8, and between the loading funnel 12 and the mixer 13 there is a movable 16 and a fixed 17 disks with radial grooves.

The device works as follows.

The material is fed into the mixer 13, where it is mixed with the help of blades 15 fixed on the shaft 14. Next, the prepared material passes through the windows formed by the radial grooves of the movable 16 and the fixed 17 disks. When the movable 16 disk is displaced relative to the fixed 17, the window area changes by overlapping the slots of the disks 16 and 17 to the required value, thereby ensuring the dosing of the material and the required mixing quality. The pressed material is fed to the screw 8, which feeds it to the radial wheel 3. Due to the pressure created by the radial wheel 3, the material is pressed through the radial holes of the ring matrix 2. The screw 8 is driven through the material from the radial wheel 3 and has a lower rotation speed, than radial wheel 3.

Directly connecting the auger with a movable disk having races that are located in the grooves of the radial wheel allows material to be fed directly to the blades of the radial wheel, while providing the necessary pressure for the smooth operation of the radial wheel.

A reduction in the path of movement of material in the inter-blade channels of the screws and races increases the reliability of the device. The use of movable and fixed discs at the exit from the mixer allows the dosing of the material to be fed to the auger, thus ensuring the necessary quality of its mixing.
