Abstract

Usage: processing of various press materials in screw presses, Essence: supplying the end surfaces of the blades with fingers placing the drum inside the hopper, performing opposite surfaces of the hopper with annular grooves, the location of the grooves eccentric relative to the axis of rotation of the drum, placing fingers with the ability to move along the annular grooves, connection drum and auger with each other by means of a gear pair. 3 ill.

Description

The invention relates to equipment for processing various press materials, in particular to worm presses.

The purpose of the invention is to increase the productivity of the press and simplify its design.

Figure 1 shows a general view of a worm press; figure 2 - section aa in fig. 1; in Fig.Z - section bB in Fig.1.

The screw press comprises a housing 1 with a drive screw 2. A feed hopper 3 is mounted on the housing 1 with a feed drum 4 with blades 5. The end surfaces of the blades 5 are provided with fingers 6, and the inner opposite surfaces of the hopper 3 are made with annular grooves 7 and 8 located eccentrically relative to the rotation of the drum 4. The blades 5 are installed with the possibility

reciprocating movement in the radial direction by placing the fingers 6 with the possibility of movement along the annular grooves 7 and 8. The drum 4 and the screw 2 are interconnected by a gear pair 9 and 10.

The worm press operates as follows.

The material enters the hopper 3. During the rotation of the screw. 2 ot of the drive (not shown), through the gear pair 9 and 10, the drum 4 rotates. When the drum 4 rotates, the blades 5 interact by means of the fingers 6 with the ring grooves 7 and 8, perform a reciprocating motion in the radial direction. The material is captured by the blades 5 from the upper part of the hopper 3 and is transported to the rotation zone of the screw 2,

where further seals and pushes through holes in the housing 1.

This screw press is simpler in design and higher in productivity. This is achieved by the fact that the material is fed to the screw by blades mounted with the possibility of radial movement due to the fingers connected with them, interacting with eccentric grooves.

In this case, the amount of material supplied to the rotation zone of the screw can be increased, because no perforated drum.

In addition, eliminating the perforated drum, replacing the cam with eccentric grooves, and coupling the drum to the auger gear pair simplifies the design of the press.
