Description

Hybrid Cleaning System {HYBRID CLEANING SYSTEM}

The present invention relates to a hybrid cleaning system, and more particularly, by washing by spraying a material with excellent cleanability and environmentally friendly dry ice and harmless and high hardness, cleaning workability and cleaning efficiency is improved, The present invention relates to a hybrid cleaning system capable of performing repainting effectively because surface treatment required for removal and painting can be performed simultaneously.

In general, various mechanical devices, parts, press molds, injection molds, etc. are attached to the foreign matter is to perform a cleaning operation to remove them. In particular, since the mold remains after the residue of the raw material is bound to the inner surface of the mold, the mold is repeatedly produced without removing the defective product.

The cleaning operation is usually performed using a laser cleaner, a sand blast cleaner, etc., but the laser cleaner is not only expensive but also has a limit to completely remove foreign matters stuck to the curved part of the object to be cleaned. The high pressure jet sand not only causes the abrasion of the cleansing material but also has a limit of increasing the contamination as the spray material is inserted in the curved gap.

In order to make up for this drawback, recently, a cleaning apparatus for performing a cleaning operation using dry ice has been proposed as shown in Korean Patent Publication No. 10-0742717.

The washing apparatus includes a dry ice supply apparatus 20, a washing drum 100, a lifting device 40, and a moving means 30 for moving the dry ice supply device, the washing drum, and the lifting device. By spraying the dry ice supplied from the dry ice supply device 20 through the connection hose 130 at high speed, the tire mold is cleaned.

Unlike the sand blasting method, the above-mentioned washing apparatus performs washing using dry ice, and unlike the sandblasting method, the washing material does not remain, and the raw material of the tire is made of natural rubber (NR) or styrene butadiene (SBR). Considering that it is a rubber of rubber series, it has a relatively high cleaning efficiency. However, when cleaning molds such as oil seals and die casting molds that are made of fluorine and silicone rubber as raw materials, sufficient cleaning efficiency can be obtained. There is no problem.

More specifically, the fluorine and silicon-based rubber has a very high adhesive strength with the mold, so that when foreign matter is sintered to the mold, even if spraying dry ice having a low hardness (Moss hardness: 1.5), the foreign matter can be removed cleanly. It has no limitations. For this reason, since the sandblasting cleaning apparatus must be performed in parallel, the washing operation is very difficult and time consuming, and also causes the problem of contaminating the object to be cleaned.

On the other hand, the truss of the piers, industrial steel structures, steel structures of buildings, etc. are applied to prevent corrosion of the internal metal and to maintain the beauty of the appearance, the coating surface formed through the painting work has a certain durability When the endurance is reached, the existing coating layer is peeled off and repainted.

For repainting, peel off the coating layer with a chisel, etc., and remove the foreign substance attached to the surface, and then perform a surface treatment operation to give a constant surface roughness to the painted surface to improve the adhesion of the paint. Will be implemented.

Accordingly, in order to ensure stable washing, first, the repainting work is performed by using a dry ice cleaning device to remove foreign matters, and then a surface treatment work is performed using a sandblasting device. The operation is very complicated and time consuming, and the environment is contaminated by sand and foreign substances scattered during sandblast cleaning.

The present invention has been proposed in view of the above, by providing a dry cleaning with excellent cleaning properties and a material with a high hardness to wash, to provide a hybrid cleaning system to improve the workability and cleaning efficiency of the eco-friendly cleaning. have.

The injector may have a large diameter portion formed on one side and the other side such that dry ice flows in and out, and a vanture tube having a small diameter portion to which the high hardness material supply pipe is connected between the large diameter portions.

The washing performing means may include an extension part that contracts and expands at a lower periphery of the cover body. In this case, the extension may be formed of a bellows structure.

In addition, the cover body may be formed of a transparent material, or a see-through window may be formed on a part of the body to enable the internal perspective. In this case, the cover member may be a brush member to be in contact with the object to be cleaned therein.

One end is connected to the cover body, it may be provided with a connecting rod, the connection hose, the high hardness material supply pipe, and the suction pipe connected to the foreign material removal device is built.

On the other hand, the input unit for inputting a control signal, such as on / off operation of the dry ice supply device, the compressed air supply unit, the high hardness material supply unit, and the foreign matter removing device, driving strength and the like; And a control unit controlling driving of the dry ice supply device, the compressed air supply unit, the high hardness material supply unit, and the foreign material removal device according to a signal applied from the input unit.

In addition, the dry ice supply device, the compressed air supply unit, the high hardness material supply unit, and may include a transport cart on which the foreign material removal device is mounted.

The hybrid washing system of the present invention can effectively remove various kinds of foreign matters by performing a washing action by spraying a relatively large amount of dry ice and a relatively high hardness, while removing the foreign matter while rapidly expanding the volume. In particular, it is possible to easily remove foreign substances that are not easily removed, such as fluorine, silicone-based rubber by the high hardness material.

In addition, when a high hardness material that is harmless to the human body is applied as a material having a high hardness, dry ice and a high hardness material that are harmless to the human body may be used to clean the environment. In addition, since the foreign matter is removed in a sealed state, the cleaning operation can be performed cleanly without contaminating the surrounding environment.

On the other hand, since dry ice and a material with high hardness are sprayed together to remove foreign substances, the surface treatment of the surface of the object to be cleaned can be carried out at the same time, thus reducing the refinancing work period and labor costs. There is an effect to reduce.
