Description

[Detailed description of the invention] The present invention is a multi-tank solvent cleaning device in which a plurality of cleaning tanks having different cleaning purposes, such as a hot liquid cleaning tank, a cold liquid cleaning tank, and a steam cleaning tank, are divided into a cleaning tank main body. Conventionally, in this type of washing equipment, the entrances and exits for the liquid to be washed are either provided at the top of each washing tank and covered with a covering lid, or a single door is installed that spans each washing tank. The method used was to provide a large entrance and exit and cover it with a single covering lid.

In the former case, it is necessary to open and close the covering lid of each washing tank each time an object to be washed is inserted into each washing tank. For example, when three types, A, B, and C are formed in the washing tank body, When moving objects to be washed from tank A to tank B, open the covering lid of tank A, take out the objects to be washed, close the covering lid of tank A, and then move the covering lid of tank A to tank B.
It takes a tedious time to open the covering lid of the tank, insert the items to be washed into tank B, and close the covering lid of tank B.
, C are each loaded with an object to be washed, and the object to be washed is moved sequentially through each washing tank while the washing operation is performed, which makes the work procedure extremely complicated. Due to the cumbersome nature of this process, the work must be carried out with a plurality of cover covers open, which has the disadvantage of increasing the diffusion of the solvent into the atmosphere.

In the latter case, where multiple tanks are covered with a single covering lid, the covering lid is large, which poses a problem in handling, and all of the multiple tanks are opened when the items to be washed are taken in and out, which prevents the solvent from entering the atmosphere. This strengthened the diffusion into the interior, making it uneconomical and causing pollution.

The present invention eliminates the above-mentioned drawbacks, and one embodiment of the invention will be explained below with reference to the drawings. The main body of the washing tank is divided into a plurality of washing tanks having the purpose of washing, and a cooling coil 5 is wound around the inner surface toward the upper end to form a cooling drying phase 6.

Reference numeral 7 denotes a telescopic lid body formed in the opening 8 of the washing tank main body 1 on the upper surface of the cooling/drying phase 6; The inlet/outlet 13 is formed into a cylindrical shape, a fan 15 is provided on the side surface of the cylindrical body 14, an exhaust pipe 16 is connected to the exhaust pipe 16 which can be bent to an appropriate position, and guide rails are installed on the cleaning tank body 1 on both sides in the expansion/contraction direction of the covering material 9. (not shown) is provided so that the covering material 9 and the cylindrical body 14 can move stably through the opening 8.

17 is a cooling pipe provided in the cold liquid washing tank 3, and 18 is a heating heater provided in the steam washing tank 4.

Furthermore, the plurality of washing tanks provided in the washing tank main body 1 are not limited to the above-mentioned temperatures, cold liquids, steam, etc., but can store washing liquids made from different solvents in the form of hot liquid or cold liquid, All may be hot or cold liquids.

In the structure as described above, in order to take the objects 11 to be washed into and out of the respective washing tanks 2, 3.4, the covering material 9 must be expanded and contracted to the top of the target washing tank, for example, the hot liquid washing tank 2. While moving through the entrance/exit 13, the lid 12 is opened and the object 11 to be washed is taken in and out.

In addition, when the object to be washed 11 is located in the temperature liquid washing tank 2, it is raised to the cooling drying phase 6, and the inside of the cooling drying phase 6 is opened through the inlet/outlet 1.
3 to the upper surface of the cold liquid cleaning tank 3, and the cold liquid cleaning tank 3
immerse in it.

The same applies to the case where the object to be washed 11 in the cold liquid washing tank 3 is transferred to the steam washing tank 4.

When the lid 12 is opened to take in and out the object 11 to be washed, move it, etc., the fan 15 is operated to suck the solvent gas near the entrance/exit 13 to prevent solvent vapor from flowing out from the entrance/exit 13. .

As mentioned above, the present invention is economical because there is less solvent gas flowing out because only the entrance with the area necessary for the ingress and egress of the object to be washed is opened for the movement, etc. of the object to be washed. It will be possible to prevent the occurrence of pollution, etc.

Further, since the inlet/outlet can be freely moved on the upper surface of the plurality of tanks while expanding and contracting the elastic material, work efficiency is good, and the trouble of repeatedly opening and closing various covering lids can be completely eliminated.
