Description

The invention relates to dry cleaning in industrial plants using volatile solvents, in particular to devices for cooling water in dry cleaning machines.

A known machine for dry cleaning products containing a washing drum, a condenser and a water distribution mechanism associated with a water tank, the inlet of which is connected via a pipe to the outlet of the condenser, and the outlet of the reservoir is che. the cut pump and piping is connected to a water cooler £ 1].

In a known machine, the water in the second tank is cooled in a water cooler, mixed in the first tank with warm water from the load and, when heated, enters the load. For dry cleaning machines, this is unacceptable, since the supply of cooling water with an increased temperature to the condenser of the machine leads to an increase in drying time, energy costs and an increased specific consumption of volatile solvent.

The purpose of the invention is improving the cleaning efficiency ..

This goal is achieved in that the water cooler is connected to the inlet of the condenser through a water distribution mechanism, and the water tank is connected to the outlet of the condenser through a check valve.

The drawing schematically shows a machine for dry cleaning products, General view.

The machine contains a washing drum 1, a condenser 2, connected by pipelines 3 with a water freon cooler 4 of water and a tank 5 for water. The inlet of the water tank through a pipe 3 is connected to the output of the condenser 2, and the outlet of the tank 5 through a pump 6 and pipes 3 is connected to the water cooler 4. The water cooler 4 is connected to the inlet of the condenser 2 through a water distribution mechanism 7. The tank 5 for the outlet of the condenser of the non-return valve 8. The next operation is to dry the products into the typists. The water from the reservoir 5 is pumped to the chiller by connecting it to 2 through the device.

In the process of a non-chemical body 4, water is cooled to a minimum temperature in it and through the water distribution mechanism 7 enters the condenser 2 of the machine, intensively condensing the vapor of the volatile solvent in the machine, and passing through the check valve 8, partially heated, enters the tank 5 for water.

In the process of operation of the machine, along with the operation of drying products, carry out technological operations of washing, spinning and airing. When performing these operations, occupying half of the total cycle time, water is circulated bypassing the heat load (condenser 2). In this case, the water of the tank 5 is pumped by pump 6 to the water cooler 4, it is cooled, and by means of the water distribution mechanism 7 it enters the tank 5. This allows maximum cooling of the water in the tank 5 (accumulate cold energy) before starting

The body of water 4 is cooled therein to a minimum temperature and through the water distribution mechanism 7 enters the condenser 2 of the machine, an intensively condensed vapor of a volatile solvent in the machine and, passing through the check valve 5 partially heated, enters the water reservoir 5. In the process of machine operation, along with the drying of products, technological operations of washing, pressing and airing are carried out. When performing these operations, which occupy half of the total cycle time, water is circulated, min thermal load (condenser 2). At the same time, the water of the tank 5 is pumped to the water cooler 4 by the pump b, cooled, and through the water distribution mechanism 7 enters the tank 5. This allows the water in the tank 5 to be cooled as much as possible (to accumulate cold energy) before the start of the drying operation, and to intensify the process of drying products. The invention The machine for dry cleaning products containing a washing drum, a condenser and a water distribution mechanism associated with a water tank, the inlet of which is connected to the outlet of the condenser through a pipe and the outlet opening of the tank through a pump and pipelines connected to a water chiller in order to increase the cleaning efficiency, the water cooler is connected to the inlet of the condenser through a water distribution mechanism, and the water tank is connected to the outlet of the capacitor via a check valve.
