Description

A centrifugal separator typed dust collecting chiller for dry cleaning}

The present invention relates to a centrifugal cooling dust collector of dry washing, and more particularly, to separate and discharge the organic solvent, wet steam, and foreign matter contained therein by centrifugal force, and to recycle only clean dry air, thereby ensuring good drying and washing of laundry. The present invention relates to a dry laundry centrifugal cooling dust collector which achieves the above effects by preventing the environmental pollution by facilitating the discharge of solvents and foreign matters, and by allowing the cooling of wet steam by a simple mechanical structure.

Bedding, clothing, etc. made of various materials can not function if left in a contaminated state, regular washing is required. In particular, in the case of silk fabrics, the advantages of the material are greatly impaired by the mechanical impact applied to the laundry. Therefore, in order to maintain its characteristics, dry textile washing methods such as dry cleaning are used in addition to the mechanical washing method. .

Dry cleaning is a method suitable for washing products that may be damaged by shrinkage, relaxation, fluff, wrinkles, discoloration, etc. caused by washing with water. The organic solvents used are synthetic solvents such as perchloroethylene and petroleum solvents. Solvents and the like are used.

However, the organic solvent used therein is toxic and thus adversely affects the human body, causing environmental pollution. Therefore, in the dry cleaning apparatus using the same, a sealing device for circulating the organic solvent is required, and a structure that can be completely collected and disposed together with the foreign matter after washing is urgently required.

It is an object of the present invention to easily separate and discharge the organic solvent used in dry washing with air together with the moisture contained therein and foreign substances generated during washing, recirculating only clean air to mix the new wet steam and the organic solvent again. To be used for drying, to achieve this, the housing and the inner wall are combined to form a conduit through which cooling water flows, and a circulation pipe having spiral ribs formed on an outer side of the inner wall is installed, The circulation fan is installed at one end, and the foreign matter, the organic solvent, and the wet steam are circulated through the driving of the circulation fan, and only the dry air is recycled to provide a dry washing centrifugal cooling dust collector.

Hereinafter, the configuration and operation of the present invention will be described in detail with reference to the accompanying drawings.

In the present invention, a mixed steam inlet 1 is formed at an upper portion, a dust collection hopper 3 having an outlet 2 is formed at a lower portion thereof, and a housing of a tubular body having a cooling water inlet 4 and a cooling water outlet 5 formed therein. 6); An inner wall body 9 having upper and lower flanges 7 of the tube bent outwardly in close contact with the inner surface of the housing 6 to form a cooling passage 8 together with the housing 6; The upper end of the housing (6) while being inserted into the inner center of the inner wall (9), the dry air outlet 10 is formed on the upper end, the spiral pipe 11 is formed on the outer surface of the circulation pipe 12 and; It is installed on the top of the circulation pipe 12, the circulation fan 13 for circulating the mixed steam and dry air; characterized in that it comprises a configuration.

In the present invention, the inner wall 9 and the housing 6 may be enlarged according to the capacity. In this case, the inner wall 9 is composed of units to stack a plurality of units as necessary. It may also be carried out. That is, a plurality of the inner wall 9 may be inserted into the housing 6, and the cooling water inlet 4 and the cooling water outlet 5 may be installed at each of the inner wall 9.

The present invention having such a configuration has an embodiment as shown in Figs.

For dry washing, the high pressure water vapor and the organic solvent are mixed and circulated to the laundry and the cooling dust collector, and the foreign matter separated from the laundry by the organic solvent should be well separated and extracted from the cooling dust collector. As described above, the present invention effectively separates and discharges the organic solvent, the wet steam, and the foreign matter, thereby preventing environmental pollution and increasing washing efficiency.

That is, in the present invention, the foreign matter separated from the laundry is mixed with the organic solvent and the wet steam and introduced into the housing 6 of the cooling dust collector through the mixed wet steam inlet 1. Since the circulation tube 12 in which the spiral rib 11 is formed is installed at the inner center of the housing 6, the mixed wet steam flows downward while circulating along the spiral rib 11.

In addition, the inner wall 9 and the housing 6 form a cooling flow path 8, and the cooling water flowing into the cooling water inlet 4 flows into the cooling water outlet 5 through the cooling flow path 8.

In this way, when the coolant flows into the cooling channel 8, the mixed wet steam flows along the spiral ribs 11, and the mixed wet steam is separated from the water, the organic solvent, and the foreign matter, and is installed at the bottom of the housing 6. Gathered in (3), and only dry air flows.

As described above, in the present invention, the mixed wet steam is helically flowed by the circulation tube 12 having the spiral rib 11, and the flow path thereof is long, and foreign matter and water particles are easily separated from the dry air by the centrifugal force due to the rotation. Will be.

Depending on the capacity of the washing, the housing 6 and the circulation tube 12 may be made longer or shorter, but the present invention has a structure for facilitating this. That is, the inner wall 9 that forms the cooling flow path 8 together with the housing 6 is a unit of the tubular body having a constant height, and in the case of a large cooling efficiency, a plurality of inner walls 9 are laminated. What is necessary is just to determine and implement the height of the housing | casing 6 suited to the height of this. In this case, of course, the height of the circulation pipe 12 should also be determined accordingly. The cooling flow path 8 formed for each of the inner wall 9 has a cooling water inlet 4 and a cooling water outlet 5, and the cooling water inlet 4 and the cooling water outlet 5 are the housing 6. It is installed to penetrate through.

The organic solvent, water particles, and foreign matter separated from the cooling dust collector accumulate in the dust collecting hopper 3 and are discharged to the outside through the outlet 2.

And the flow of the mixed steam and dry air is made by a circulation fan 13 installed on the upper end of the circulation pipe 12, of course, in addition to the circulation fan 13 may be provided with a separate fan for the circulation of the mixed wet steam, Naturally, it is driven by an electric motor. That is, by the circulation fan 13, the mixed wet steam is rotated helically from the outer upper end of the circulation tube 12, and the foreign matter, water particles, the organic solvent, and the dry air by the refrigerant such as cooling water flowing into the cooling flow path 8. Separated by, and only the dry air is conveyed from the lower side of the circulation pipe 12 to the upper side to be recycled to the dry air outlet (10).

The dry air thus discharged is mixed with the wet steam and the organic solvent again to dry the laundry, and then flowed into the cooling dust collector again to repeat the above process.

As such, in dry washing, water, organic solvents and foreign substances should be separated efficiently from mixed wet steam, which is to prevent environmental pollution and to increase drying efficiency.

Therefore, in the present invention, the heat exchange flow path of the mixed wet steam is long by the spiral rib 11 formed on the outside of the circulation pipe 12, which is composed of the inner wall 9 of the unit which can easily change its length according to the capacity. By forming, it is very easy to separate. That is, since the dry air, the organic solvent, water and the foreign matter are reliably separated, the present invention eliminates the trouble of having to filter the outdoor air again.

The mixed wet steam which has been washed according to the present invention as described above is circulated and cooled long along the circulation pipe 12 in which the spiral ribs 11 are formed, and is preferably cooled by the cooling flow path 8 through which the refrigerant flows. And since the foreign matter can be separated and extracted by centrifugal force, only the clean dry air can be recycled, and the new wet steam and the organic solvent can be mixed again and used for drying, improving the drying efficiency, and reliably water, organic solvent and foreign matter. Since it can be separated and discharged, it is effective to prevent environmental pollution.
