Description

A steam cleaning machine for outdoor masonry cultural property and the cleaning method}

The present invention relates to a steam washer and washing method used for washing stone cultural assets located in the open air.

As a country with a long history, cultural properties from the Stone Age have been introduced, and stone cultural assets such as stone pagoda and Buddha statues account for almost half of all cultural assets, and more than a thousand cultural treasures, including national treasures such as stone cultural assets Although most of them are large and located outdoors, the damage of stone cultural properties is seriously undermined by physical and chemical factors such as environmental pollution due to weather, freezing, melting and acid rain, and biological factors such as moss and microorganisms. As such, it is urgent that the preservation treatment of precious Korean stone cultural properties damaged by weathering is removed or delayed by removing or delaying the progress of hydration, oxidation, and chelate, which are damaging factors due to weathering.

Most cultural assets located outdoors are covered with microorganisms such as contaminants, moss, and bacteria, and these are not only damaging the appearance of the stone but also promote the damage, so it is necessary to wash them for long-term preservation of the stone cultural property.

However, currently used stone washing means are mainly washed with water and a brush or chemicals, the method of brush is left in the open air for a long time there is a risk of damaging the stone cultural properties weakened by weathering It is not able to completely remove microorganisms parasitic in stone cultural properties, and cleaning with chemicals also includes acid or basic chemicals such as AC322, AB57, K101, K201, etc., which include fungicides and antibiotics, but they are limited in preventing weathering of stone products. Rather, there was a side effect of corrosive stone by chemical action of these chemicals such as acid or base.In addition, the method of cleaning with these brushes and chemicals washes most large stone cultural assets such as stone towers and Buddha statues while they are located outdoors. In order to wash indoors, it is necessary to disassemble and transport it indoors. This was inconvenient for.

The present invention is to solve this problem is to remove the moss, microorganisms and chemical contaminants, etc. which are coated on the surface of the stone while preventing the damage to the surface when washing the stone cultural property, and the object is to wash the stone outdoors have.

In order to achieve this purpose, by washing the stone with a steam washer to prevent the rock from breaking out when brushing to remove the contaminants coated on the stone and to prevent secondary weathering due to chemical cleaners,

Steam washing machine of the present invention is composed of a heating water tank and a burner and a steam gun, the wheel and the handle is attached to the steam cleaner so that it can be used while moving outdoors, the flame from the burner located at the bottom of the heating water tank affects the external wind It is equipped with a pressure gauge that senses the pressure in the bottom of the heating tank, a pressure gauge that senses the pressure in the heating tank, a safety pin, a steam control valve, and a water level sensor that senses the level of the heating tank. It is equipped with a burner controller which controls the burner's heating amount in response to the signal of the water level sensor, and the steam gun is provided with a steam controller that controls the pressure of steam passing through the nozzle inside the steam gun by spraying steam on the object to be cleaned. It is characterized by that.

Referring to the steam cleaner (1) of the present invention as follows.

Steam cleaner 1 of the present invention is composed of a heating water tank (2), a burner (3) below the heating water tank (2), and a steam gun (4) above the heating water tank (2)

On top of the heating bath (2) is a handle (5) for holding and moving the heating bath (2), a water inlet (6) for injecting water, and a pressure gauge (7) for sensing the pressure in the heating bath (2) And, there is a safety pin (8) for the pressure in the heating tank (2) to maintain the set pressure, and a steam control valve (9) for adjusting the pressure of the steam primary,

A water meter 10 for measuring the water level in the heating bath 2 on the side of the heating water tank 2, and a water level sensor 11 for stopping the heating of the burner 3 when water is used to reach the limit. Is mounted, the asbestos layer 12 is formed so that the heat insulation and insulation,

The bottom of the heating bath 13 is recessed inward so that the flame of the burner 3 is less affected by the wind and concentrated in the heating bath 2 when washing the stone located outdoors such as a mountain or field.

Burner (3) has a wheel (15) attached to the lower portion of the steam washing machine (1) to facilitate the movement and is connected to the butane gas cylinder (14) serving as a heat source, the heat of the water tank (2) There is a burner controller 16 which receives a signal from the water level sensor 11 and stops combustion of the burner 3 when water is used to reach the limit.

The steam gun 4 is a device for spraying steam to the object to be cleaned, and the hose 17 connected to the heating bath 2 for a long time, the nozzle 18 for spraying steam, and the pressure of steam passing through the nozzle 18. The secondary controller is provided with a steam controller 19.

Referring to the operation of the steam washer 1 of the present invention.

After moving to the outdoor location where the stone to be washed by the steam washer (1) is located, check the amount of water in the heating water tank (2) with the water meter (10), and burn the burner (3) after a predetermined time. When the water inside is boiled and steam is generated and the steam pressure is 7-10 kg / ㎠, the steam gun 4 is sprayed to wash the stone by spraying steam. The pressure in the heating water tank 2 is the safety pin (8). By maintaining the constant by the state that the contaminants are attached to the stone by adjusting the steam control valve (9) mounted on the heating water tank (2) first, while washing the actual stone and separated from the steam washer (1) The steam controller 19 is attached to the steam gun 4 according to the degree of difficulty of washing the contaminants at the working position.

In addition, when the water in the heating bath (2) is used to lower the limit level during the operation process, the water level detector (11) transmits a signal to the burner controller (16) of the burner (3), the operator directly and the heating bath (2) The flame of the burner 3 is automatically extinguished without going to the burner 3 to prevent overheating of the heating water tank 2.

The stone cultural property, which is a valuable cultural heritage that has been handed down from ancient times, is cleaned by spraying it with steam instead of a brush or chemicals. It is easy to transport and move because it is small and the wheel and handle are attached, so it can be washed outdoors without disassembling the cultural property and transporting it to the room, and the bottom of the heating tank is recessed inward. Since the burner's flame can be concentrated in the heating bath without being influenced by the wind when it is washed outdoors, it can improve the thermal efficiency. In addition, it detects the water level in the heating tank and consumes the detected water to reach the limit level so that the flame of the burner can be automatically extinguished. Therefore, the steam pressure can be adjusted secondly, so the stone to be cleaned is large and high, so when the worker is washing away from the steam washer, the operator can check the amount of water during the operation or overheat the heating bath without going to the heating bath to adjust the steam pressure. It can be prevented and cleaned by adjusting the steam pressure at the working position.
