JPS58201A - Drying tank for vapor of "flon(r)" - Google Patents

Abstract

PURPOSE:To dry objects to be washed without staining the objects by feeding ''Flon '' liquid forcibly into a water separator, removing the water and washing liquid in said liquid and generating only the vapor of the ''Flon ''. CONSTITUTION:The ''Flon '' liquid 2 in the lower part of a body 1 of a drying tank is heated with heaters 3 to generate ''Flon '' vapor. An object 4 to be washed that has gone through a washing stage is dried by this vapor. The ''Flon '' liquid and water condensed by contacting condensing coils 6 and the object 4 are captured by receiving trays 5, 7, and are fed to a water separator 10, after which only the ''Flon '' liquid is pressurized by a pump 15, is filtered by a filter 14 and is discharged to the ''Flon '' liquid surface in the body 1 through a discharge hole 13. As a result, the water and washing liquid floating on said liquid surface are forced toward an intake part 12 on the top surface of the liquid and are captured in the part 12, from which they are fed to the separator 10, whereby they are subjected to sepn. Only the ''Flon '' liquid is returned to the body 1.

Description

DETAILED DESCRIPTION OF THE INVENTION This article relates to a fluorocarbon vapor drying tank. Freon Vapor Drying mFi Ultrasonic Cleaned Precision Stool 5. It is often used for drying parts, but water, alcohol, etc. get mixed into the Freon liquid, and this can cause stains on the items being cleaned. there were. - Figure 1 shows a typical conventional fluorocarbon vapor drying tank, in which a fluorocarbon liquid 2 is stored at the bottom of the tank body 1, and a heater 3 disposed on the bottom of the tank body 1 removes this fluorocarbon. Liquid 2 was heated to generate steam. The object to be cleaned 4 to be dried is placed in the center of the tank body 1, and the object to be cleaned 4 is placed thereon.

Furthermore, a condensing vibro through which cooling water was passed was arranged on the upper side wall of the tank body 1. and the saucer 5,
At 71 and 71, the fluorocarbon liquid and other substances were separated due to the difference in specific gravity, and only the fluorocarbon liquid was refluxed into the tank, resulting in a condition similar to f.

In this conventional steam cleaning tank, moisture condensed on the object to be cleaned 4 and the condensing coil B, and cleaning liquid such as alcohol adhering to the object to be cleaned 5 and 4 drip onto the trays 5 and 7. It is unavoidable that droplets from the removal fall into the Freon liquid 2 on the premises, and that water condensed on the side walls of the tank mixes with the Freon liquid 2 on the premises. Since there was no means to separate them, these were gradually accumulated in the fluorocarbon solution 2 in the premises and the amount thereof increased over time.

Therefore, in this conventional mounting/direction method, water and cleaning liquid mixed in the fluorocarbon liquid are also evaporated by the zero heat of the heater 5, which causes stains on the cutter 4 to be cleaned.

This Yumei eliminates the above-mentioned drawbacks of the fluorocarbon vapor drying tank.The fluorocarbon liquid is overflowed by pump circulation and is forcibly sent to the water separator, and the water and cleaning liquid in the fluorocarbon liquid are removed by the water separator. To provide an excellent fluorocarbon vapor drying tank which is designed to generate only steam and can dry objects to be cleaned without staining them. - Hereinafter, the configuration will be explained in detail based on an embodiment of the present invention shown in FIG.

A saucer 7 located below the condensing coil 6 is communicated with a water separator 10 via a pipe 9, and a saucer 5 below the material to be dried 4 is communicated with a water separator 10 via a pipe 11.
This water intake part 12 is connected to the water separator 10 through a pipe 12', and the side wall facing the water intake part 12 has a wall that is connected to the liquid level. An open discharge hole 13 is provided, and this discharge hole 13 is connected via a filter 14 and a pressurizing pump 15 to a discharge hole 16 of the pre-water separator 10 .

Note that the water separator 10 is a specific gravity type water separator that performs separation using the difference in specific gravity between Freon and other liquids, and 17.
18 is a partition wall that separates the water inlet side and the discharge side. Since the rest is the same as the conventional one, the same reference numerals are given and the explanation is omitted.

This invention recreates the structure described in the paper, and similar to the conventional one, the fluorocarbon liquid 2 at the bottom of the tank body 1 is heated by the FC heater 3 to generate fluorocarbon vapor. Dry item 4. The fluorocarbon liquid and water that condensed on contact with the condensing coil 6 and #4 to be cleaned are collected in the trays 5 and 7, and sent to the water separator 10 where the fluorocarbon liquid, water, and cleaning liquid are separated. Only the fluorocarbon liquid is pumped. 15 , filtered by a filter 14 , and discharged from a discharge hole 16 onto the surface of the fluorocarbon liquid in the tank 1 .

On the other hand, Freon has a much higher specific gravity than water or cleaning liquid, and if water or cleaning liquid is mixed in (7), these will float on top of the Freon liquid and form a hawk. When discharged from the discharge hole 13, the water floating on the surface of the fluorocarbon liquid and the cleaning liquid are transferred to the upper surface of the fluorocarbon liquid at the water intake part 1.
2, is collected by the water intake part 12, and sent to the water separator 10 for separation, and only the fluorocarbon liquid is returned to the tank body 1.

Therefore, the cleaning liquid and condensed water adhering to the object to be cleaned collide with the saucer, become droplets, and fall into the Freon liquid in the tank body.
Even if water condenses on the condensing coil or the side wall of the tank body and drips into the Freon liquid, and impurities such as water or cleaning liquid get mixed into the Freon liquid, these impurities are constantly separated from the Freon liquid. It can generate extremely high-purity fluorocarbon vapor, and has the excellent effect of drying the items to be cleaned without staining them, unlike conventional ``fluorocarbon vapor drying tanks.''
