Abstract

Usage: cleaning products in a washing liquid with floating abrasive particles, Summary of the invention: the products are processed by placing the products in a washing liquid with floating abrasive particles, the latter being formed as a layer on the surface of the liquid, in which turbulent motion is excited by upward flows uniformly distributed over fluid volume. In the installation there are a number of evenly spaced; along the bottom of the bath of the guide troughs with outlet openings along their length, each of which is joined to the discharge pipes in which the bladed screws are located. 3 s P. f-ly, 2 ill.

Description

The invention relates to the cleaning of products, mainly in the rubber industry, in particular, to technology and devices for cleaning molds for the manufacture of dipped products from latex,

The purpose of the invention is to remedy these disadvantages.

In FIG. 1 shows an apparatus for cleaning products, general view; in FIG. 2 is a plan view with guide channels placed along the bottom of the bathtub.

The device for carrying out the method comprises a bath 1 for washing liquid 2 and abrasive particles 3, the thickness of which is 0.6-0.8 times the immersion depth of the products in the washing liquid, cassette 4 with cleaning forms 5, means for creating a turbulent movement 6, including propellers 7, placed in the discharge pipes 8, passing into the guide grooves 9 with output mercury holes 10 evenly spaced. along the bottom of the bath, belt drive 11 rowing

screws, electric motors 12. The number of propellers 7 with discharge pipes 8 and grooves 9 is set depending on the size of the bath.

In the guide channels, flow dividers 13 are installed, the number of which is determined by technological necessity.

The means for creating a turbulent movement 6 is mounted on one of the ends of the bath 1, and the discharge pipes 8 are shielded by a grid 14 to prevent the abrasive particles from entering the discharge pipes 8. The washing fluid flows are indicated 15, the adjusting mechanism 16 in contact with the propeller shaft 7.

The method is carried out as follows.

Fill bath 1 with washing liquid 2 to a predetermined level, placing granules of elastically deformable material to a level that provides a layer of

ate

with

0.6-0.8 immersion depths of the cleaned product in the washing liquid, immerse the cartridge A with the cleaning forms 5 in the bath 1. Using the means for creating a turbulent movement 6, flows of washing liquid 15 are uniformly distributed over the volume of the bath 1, which, directed under pressure from the bottom up through the washing liquid, create turbulent fluid flows and involve granules of elastically deformable material in this movement. During the movement, the granules hit the surface of the molds 5, loosen the dirt, and the washing liquid is additionally washed away.

After the cleaning cycle is completed, the cassette 4 is removed.

Installation for implementing the method works as follows.

In the bath 1 pre-filled with washing liquid 2 and elastically deformable material 3, a cassette 4 with forms 5 is placed.

The adjusting mechanism 16 sets the propellers 7 to a position corresponding to the desired flow rate.

By turning on the electric motors 12 through the belt drive 11 the propellers 7 are rotated, as a result of their rotation, the washing liquid flows under pressure from the discharge pipe 8 into the grooves 9, and through the outlet openings 10 is directed by flows 15 from the bottom up, causing the washing liquid to turbulent movement 2 and elastically deformable material 3, After a predetermined time -. neither the electric motors 12 are turned off, the washed forms 5 on the cassette 4 are lifted.

Using the proposed technical. solutions will make it possible to improve the quality of mold cleaning for the manufacture of dipped latex products and to intensify the cleaning process.

Formula of the invention

Claims (5)
