Description

f

The invention relates to mechanical engineering, and can be used in the wine-making and canning industry.

The aim of the invention is to increase productivity by increasing the degree of spin.

Figure 1 shows a schematic press, a general view; figure 2 - the conveyor belt with the node block pressing drums; on fig.Z - the block of the pressing drums; figure 4 is the same, section aa on fig.Z; FIG. 3 is a view of FIG. 3. FIG.

The press contains a press drum 1 mounted on a frame (not shown), a belt press conveyor 2, a device 3 dL supplying the mash to filter press belts, a device 4 for discharging marches, 5 guides and tension 6 rolls for filter presses and drainage belts and washing device 7 bunker and juice collector (not shown).

The drum 1 is covered by filtering pressure tapes 8, between which drainage tape 9 is placed.

The pressing belt conveyor 2 contains drums 10, covered by rubber-fabric tape 11, on which drainage strips 12 are attached. Kon-2 is installed with a gradually decreasing gap between the first and last drums 10 and the pressing drum 1.

The drums 10 are grouped into pressing blocks 13 and are covered by a multi-chain 14, the drums 10 of each pressing block 13 are mounted on axles 15 and placed between the cheeks 16. The tension device of the chain 14 includes

The first pressing unit along the pulp has a belt tensioning device (not shown). In addition, each pressing unit is equipped with a device for adjusting the gap between the pressing drum 1 and the pressing conveyor 2, made, for example, in the form of bolted connections and adjustable adjustable bolts (not shown).

The press works as follows.

Fruit pulp is fed to the ribbons of the feeding device 3 through the windows across the entire width of the ribbons. The drum 1, rotating, moves the filter press bands 8, which pull in the pulp. and pressed it. Then the pulp enters the area of the pressing conveyor 2. The pressure of the pressing is increased by gradually reducing the gap between the drum 1 and the conveyor 2. At the section of each block 13, pressing is performed with a constant pressure determined by the tension of the chain 14. At the exit of the pressing zone the filter belts 8 and the drainage band 9 is separated and the husks are unloaded from the press.

The coverage of multi-pitch chains of blocks of the pressing drums makes it possible to avoid a drop in the pressure of pressing in the areas of the pressing conveyor between adjacent drums and to increase the degree of spinning. Moreover, the number of blocks 13 must be at least three, and the number of reels in each block must be at least two.

The economic effect of implementing the invention is achieved by increasing productivity.
