Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention is used for cleaning and deliquid cleaning in dry cleaning, in which soiled clothes, blankets, etc. are continuously transported using a conveyor in a naturally spread state. This relates to liquid equipment.

BACKGROUND ART Conventionally, dry cleaning of dirty clothes, blankets, etc. has been carried out intermittently using a rotatable perforated drum. That is, a perforated drum is provided approximately concentrically and rotatably within an outer cylinder installed horizontally, and after a certain amount of objects to be processed, such as clothes, is accommodated in the perforated drum, the drum is sealed. The steps of washing, deliquification, drying, and deodorization are performed in sequence.

In the cleaning step, a solvent solution is supplied into the porous drum, and while the porous drum is rotated at a low speed, a kneading action or a falling action is applied to the workpiece to wash the workpiece. In the liquid removal step, the solvent liquid is discharged from the porous drum, and the porous drum is rotated at high speed to remove liquid while swinging the object to be processed. In the drying step, the porous drum is rotated at low speed while supplying hot air into the porous drum to dry the object. In the deodorizing step, the porous drum is rotated at low speed while supplying air from outside the machine to the porous drum to remove the solvent odor contained in the object to be processed.

Problems to be Solved by the Invention According to conventional dry cleaning equipment, a large number of objects to be processed, such as clothes, are put into one porous drum, resulting in unnatural lumps of objects. . Therefore, if dirt detached from the object to be treated during the cleaning process contaminates the solvent solution, the dirt in the solvent solution will re-adhere to the object by the time the cleaning is finished, resulting in a very high rate of re-contamination. It was hot. Furthermore, since the objects to be processed are packed into the porous drum, more physical force than necessary, that is, friction and impact, is constantly applied to the objects for a long period of time. As a result, the items to be processed may twist or shrink, lose their shape, or become deformed, and especially for clothing that requires delicate handling, a single dry cleaning may cause abnormal shrinkage or deterioration of texture, making it unwearable. There was a problem.

A deodorizing mechanism 13 is arranged after the drying mechanism 12. This deodorizing mechanism 13 includes an exhaust duct 50 provided in a part of the deodorizing housing 4.
is connected to a known exhaust gas treatment device.
Therefore, during operation, outside air flows into the interior through the passage port 46 of the deodorizing housing 4, and at the same time, solvent gas components are removed from the object to be treated 10 in the deodorizing housing 4 by the suction force of the exhaust gas treatment device.

An exhaust duct 51 is provided in a part of the cleaning housing 2.
The exhaust duct 51 is connected to the above-mentioned known exhaust gas treatment device, and the air pressure inside the cleaning housing 2 is made negative.

Therefore, the vaporized high-concentration solvent gas in the cleaning housing 2 and the drying housing 3 is sent to the exhaust gas treatment device, and there is no risk of it flowing out through the passage ports 7, 48 of the cleaning housing 2.

Next, the procedure for dry cleaning objects to be processed such as clothes will be explained as follows.

A new solvent solution 17 is supplied to the secondary cleaning tank 15 with a high liquid level through the solvent solution supply pipe 16.
overflows into the primary cleaning tank 14 with a low liquid level. On the other hand, the objects 10 to be processed, such as dirty clothes, are placed one by one on the end 6 of the carry-in conveyor 5 exposed to the outside, as shown in FIG. 2, in a naturally spread state. The workpiece 10 carried into the machine under negative pressure by the movement of the carry-in conveyor 5 is sent to the cleaning conveyor 19, and is sandwiched between the gap 24a between the cleaning conveyor 19 and the auxiliary conveyor 22, where the solvent liquid 17 flows. It is transferred in the opposite direction and immersed in cleaning tanks 14 and 15 in order to be cleaned. That is, the object to be processed 10 is placed in the gap 24a between the cleaning conveyor 19 and the auxiliary conveyor 22.
The substrate is sandwiched in a naturally spread state and immersed in the solvent solution 17 in the cleaning tank 14 at a low liquid level, and is first cleaned primarily. When the primary cleaning is finished, the object 10 to be treated is once lifted from the cleaning tank 14, then sandwiched again in the gap 24b between the cleaning conveyor 19 and the auxiliary conveyor 23, immersed in the solvent solution 17 in the cleaning tank 15, and then
It is then washed. Through this first to second cleaning, the object to be processed 10 is transferred to a cleaning conveyor 19, an auxiliary conveyor 22,
gaps 24a and 2 formed between 23 and 23, respectively.
Cleaning tank 1 is sandwiched between 4b in a naturally expanded state.
4 and 15, it is possible to prevent the object 10 from losing its shape or deformation, and it is also possible to sufficiently impregnate the object 10 with the solvent liquid 17 and wash it. In addition, the dirty workpiece 10 is transferred in the opposite direction to the flow direction of the solvent solution 17, and is cleaned with new solvent solution 17 during the first and second cleanings. The dirt removed from the object to be processed 10 through the secondary cleaning does not adhere to the object to be processed 10 again. Then, the dirty solvent solution 17 naturally flows down from the secondary cleaning tank 15 and finally overflows from the primary cleaning tank 14 and is naturally discharged to the solvent solution outlet 18.
On the other hand, a new solvent solution 17 supplied from the solvent solution supply pipe 16 is poured onto the workpiece 10 pulled up from the secondary cleaning tank 15 to rinse the workpiece 10 .

The workpiece 10 that has been cleaned is sent to a dewatering mechanism 11, where it is dehydrated. That is, the cleaned workpiece 10 is sent from the discharge section 19c of the cleaning conveyor 19 to the deliquoring conveyor 40, and is transported on the travel path 40a. During this transfer, the object to be processed 10 is deliquified by the suction force acting on the suction nozzle 42 .

The deliquified object 10 is sent from the deliquifying conveyor 40 to the drying conveyor 43. The above-mentioned object to be treated 1
0 is transferred by the drying conveyor 43 in a naturally spread state, and during this transfer, the hot air nozzle 4
It is dried by receiving the hot air blown from 9,49. The dried object 10 is continuously sent to the deodorizing mechanism 13 by a drying conveyor 43. Then, outside air flows into the deodorizing housing 4 through the passage port 46 to remove the solvent gas component from the object to be treated 10, and this solvent gas is forcibly sent to the exhaust gas treatment device via the exhaust duct 50.

Although two cleaning tanks were provided in the above embodiment, the present invention is not limited to this, and the number may be changed as needed.

Effects of the Invention In the present invention, since the end of the conveyor for carrying clothes, etc. is exposed outside the machine, the clothes, etc. can be continuously carried into the machine in a naturally unfolded state. Furthermore, the carrying-in conveyor is constructed separately from the subsequent cleaning conveyor, so that the carrying-in conveyor is not wetted by the solvent solution, and the exposed portion of the carrying-in conveyor does not generate a solvent odor. Furthermore, since the present invention uses a conveyor, it is possible to wash and deliquid the clothes while they are spread out naturally, and the solvent is sufficiently penetrated, without applying excessive force to the clothes. There is no twisting or shrinkage due to stress, preventing deformation, deformation, etc., and ensuring the texture of the product. Furthermore, since clothes, etc. are continuously transported using a conveyor, and washed by being immersed in a solvent solution flowing in the opposite direction to the direction in which the clothes, etc. are transported, during the transport route, the clothes, etc. As the cleaning progresses, the cleaner the solvent becomes, the dirt that has come off the clothes will not stick to the clothes again, and re-contamination can be completely prevented. In addition, since the inside of the machine is under negative pressure, no solvent gas leaks outside, and a good working environment can be maintained.
