SU1227478A1 - Device for washing porous articles from polymeric materials - Google Patents

Description

The invention relates to equipment for the production of products from polymeric materials and can be used for liquid processing, in particular for washing through a porous material, for example, from latex.

The purpose of the invention is to intensify the process of washing.

Figure 1 shows the device, a general VIEW} in figure 2 — node I in figure 1 (a pair of wash rolls with a shower head); on fig.Z - section aa in figure 2.

The device contains upper and lower flushing and squeezing rolls 1-4, respectively, a belt conveyor 5 for moving the products, dusha nozzles 6, suzhandies towards their outlet.

The nozzles 6 are pivotally fixed in the supports 7 of the upper wash rolls 1 with the possibility of pumping in the vertical plane. On the side walls of the nozzles, the rollers 9 are fixed by means of the brackets 8 to interact with the lateral surfaces w of the upper wash rolls 1. The brackets 8 are mounted for movement relative to the nozzles under the influence of the adjusting screws 10 fixed on the nozzles 6.

The device works as follows.

Sponge articles 11 to be washed are placed on the belt conveyor 5 and fed into the gap.

between the first pair of washing valcons 1 and 2 and compressed there.

At the exit from the gap between the first pair of rolls 1 and 2, the product begins to restore its original volume under the action of elasticity and at this moment it is irrigated with water from the nozzle 6. During operation, the conical nozzle 6 under the action of

10, its own weight is pressed against the surface of the upper roll 1 and is in contact with it by the rollers 8, which roll along it. When this outlet (not indicated) nozzles 6

tS is at some distance from the surface of the roll with the formation of a gap a,

The magnitude of the latter is adjusted by moving the brackets with rollers.

20 9 relative to the side walls of the nozzle 6. Depending on the size of the gap, the required amount of wash water is supplied.

Since the washing liquid flows directly to the place of the product where the volume recovery takes place, it penetrates into the pores throughout the entire volume of the product. As a result, the time to full saturation of the product is reduced. The product so charged with water is supplied to the second pair of wash rolls 1 and 2. By repeated deformation with the wash rolls, the product is completely washed and fed to the pairs of squeeze rolls 3 and 4. The pressed product is fed to the next process step.
