DE4024969A1 - DEVICE FOR SUPPLYING AND EXHAUSTING TREATMENT LIQUIDS, STORED IN LIQUID ORDER TROUGHS (BOOSTERS) IN PARTICULAR. AT DAMPERS - Google Patents

Description

The invention relates to a device for removal and Return of the treatment liquid from or in the treatment Room of steam treatment plants, such as steamers ordered liquid application troughs (boosters).

In the treatment of textile webs with treatment liquors of high chemical concentration in liquor containers through which a liquid is applied to the goods If there is a wa shutdown the treatment liquor from the containers draw marks on the goods through long duration of the Avoid exposure to chemicals. The removal and return The liquid should be as short as possible gene.

The object of the invention is to achieve the object of and returning the liquid from or into the treatment possible with simple and reliable means enable a short time.

To solve this problem, the invention proposes conditions, the liquid application flows (booster) in the steam treatment room of a damper via liquid lines with arranged outside the steam treatment room of the damper Neten collecting containers to connect to a steam supply line are connected.

It has proven to be useful to collect the  for the treatment liquid with special cooling devices to provide.

In the liquid lines for supply or discharge tion of the treatment liquid in or out of the collecting container tern, as well as for the supply of steam to the collecting container ters are to be operated manually or automatically via a switch box Table controllable solenoid valves can be arranged and before Inlet of the treatment liquid in the collecting container a level probe should be provided.

Based on the accompanying drawing, the invention is intended are explained in more detail below.

The collecting container ( 1 ) is used for short-term storage of the treatment liquor ( 12 ) from the booster ( 7 ).

The container is filled from the steam line ( 2 ) via the pressure reducing valve ( 3 ) with steam of approximately 1-1.5 bar. For the first filling, the solenoid valves ( 4 , 5 ) must be opened for about one minute to flush the air out of the container ( 1 ).

Then the solenoid valves ( 4 , 5 ) are closed. By emitting heat through the container wall, the steam condenses in the container ( 1 ) and a vacuum is created. The condensation can be accelerated by installing a cooling coil ( 6 ) through which cooling water ( 11 ) (e.g. the cold fresh water of a washing machine) flows.

If the treatment liquor ( 12 ) is now to be sucked out of the booster ( 7 ), the solenoid valve ( 8 ) is opened. The vacuum in the collection container (1) the liquor (12) is sucked into the container (1). If the fleet is completely sucked out of the booster, steam flows past the level probe ( 9 ), which can be evaluated as a signal to close the solenoid valve ( 8 ). If necessary, the liquor ( 12 ) can be cooled in the container ( 1 ) by means of cooling water ( 11 ) through the cooling coil ( 6 ). This can, for. B. an undesirable breakdown of chemicals can be prevented.

If the booster ( 7 ) is to be filled again before the goods ( 13 ) are restarted, the solenoid valve ( 4 ) is opened at the push of a button on the switch box ( 10 ), causing steam to flow into the container ( 1 ) and the internal pressure down to pressure set on the pressure reducing valve ( 3 ). Then the magnetic valve ( 8 ) is opened and the liquor ( 12 ) is conveyed by the steam pressure into the booster.

If the level probe ( 9 ) reports steam instead of liquid, the valves ( 8 ) and ( 4 ) are closed.

After the condensation of the steam in the container ( 1 ), the liquor ( 12 ) can be sucked out of the booster ( 7 ) at any time.

The collecting container ( 1 ) can be arranged below or above the booster.

By appropriate electrical control of the magnetic valves ( 4 , 5 , 8 ), the suction or return process can be automatically controlled after initiation by pressing a button or an external signal.

The use of Pumps avoided, due to the hot Kavi fleet could occur. In addition, the process of suction gens and return through the described facility very much simplified.
