Description

Paint melting apparatus for road painting {AN APPARATUS FOR MELTING PAINTS FOR ROAD LANES}

The present invention relates to a paint melting apparatus for road painting for use in solid melting of asphalt or cement by heating and melting in a field for painting lanes or pedestrian crossings on a road surface of an automobile road, and a risk of explosion during heating melting. The present invention relates to a paint melting apparatus for road painting, which is improved so as to prevent the change and to not change the physical properties.

The paint melting apparatus for painting the road surface melts the powder at a predetermined temperature while stirring it with a stirrer driven by a motor while heating a mixture of a resin composition of a solid powder state and a pigment of a required color into a container and heating it with stirring. To help.

This conventional paint melting apparatus is used mounted to the heat-sealed lane paint apparatus shown schematically in FIG. For reference, in the fusion lane paint apparatus, a paint canister 2 and a gas canister 3 are arranged side by side on a trolley of a manual vehicle having a handle 1, and the paint canister 2 has a gas inside the lower side. A burner is mounted and a manual stirrer 9 is provided on the upper side thereof, and a gate 4 for discharging molten paint is installed on one side of the outer periphery and operated to open and close by an open / close lever 5 extending to the side of the handle 1. do. A hopper 6 for guiding paint flowing out from under the gate 4 is provided, and a storage chamber 7 is provided at the lower end side of the hopper 6. The above-mentioned fusion lane coating apparatus heats paint contained in the paint can to flow down through the gate, moves with the opening and closing plate open in the storage chamber, and the paint is fused to the road surface to paint the lane or crosswalk marking. do.

The paint canister 2 of the conventional fusion lane coating apparatus is simply a conventional container, and is heated by a gas burner at the bottom to melt the paint mixture. The physical properties of the overheated molten paint may change at the local part inside the paint canister where the flame of the burner contacts, the cover may be released from the paint canister due to excessive increase in pressure inside the paint canister as it is directly heated by the burner. In this case, the worker may be injured.

An object of the present invention is to solve the problems caused by the paint melting apparatus in the conventional fusion-type road surface paint apparatus, to enable the heating of the paint melt in the container to be carried out at an appropriate temperature so that the explosion or paint of the container due to overheating It is to provide a melting apparatus for painting the road surface of the improved structure so that the problem of the physical property change of the does not occur.

In order to achieve the above object, the paint melting apparatus for road surface coating according to the present invention uses a container having a lid and a paint in the container to melt paint components such as resin and pigment in a solid state so as to paint lanes on the road surface. In the paint coating apparatus for road painting comprising a burner for heating and a stirrer for stirring the paint components in the container, the container is a double structure of the inner wall and the outer wall and filled with oil as a heating medium between the inner and outer walls. And the paint components contained in the container by the oil heated by the furnace to be melted and maintained by indirect heating at 180-200 ° C. below the boiling point.

The temperature sensor for sensing the temperature to maintain the molten state of the paint in the container is provided in the container, it is preferably configured to control the operation of the burner in accordance with the output signal of the temperature sensor.

In addition, the hydraulic motor is installed on one side of the cover provided in the upper portion of the container and the output shaft is connected to the shaft upper end of the stirrer installed in the center of the cover is configured to rotate the stirrer by the hydraulic motor.

According to the present invention, the paint components for road-painting are melted and maintained at a boiling point below the boiling point by indirect heating by means of a burner in a container filled with oil in a double wall structure, and a change in the physical properties of the paint due to explosion or local overheating of the container. No problem occurs, and by controlling the operation of the burner in response to the output signal of the temperature sensor, it is possible to perform a simple and stable road surface painting.

Hereinafter, with reference to the accompanying drawings showing an embodiment of the present invention will be described in more detail the present invention.

Figure 2 schematically shows a paint melting apparatus for road painting according to the present invention, Figure 3 is a cross-sectional view of the paint melting apparatus.

As shown in FIGS. 2 and 3, the paint melting apparatus 10 for road surface painting according to the present invention is disposed below the bottom of the container 11 having a double structure and heated by gas or petroleum. Burner 12, the cover 13 is installed on the top of the container to be opened and closed, and is installed vertically inside the cover portion agitator 14 to prevent the paint from being locally overheated.

The container 11 has a double structure in which the oil 20 is filled as a heating medium between the inner wall 15 and the outer wall 16, and the paint material contained in the container by the oil 20 heated to a predetermined temperature by a burner. As a mixture of a conventional resin and a solid state such as a pigment is melted by an indirect heating method, it is possible to prevent a change in physical properties by a direct heating method of a container having a single wall structure.

In addition, a temperature sensor 21 for measuring the temperature of the oil contained between the inner and outer walls of the vessel 11 is installed in the vessel to control the operation of the burner to control the oil temperature as a heating medium, the melting temperature below the boiling point of the paint in the vessel For example, 130-300 ° C., preferably 180-200 ° C., which allows the temperature sensor 21 to directly measure the molten paint temperature inside the vessel in a predetermined temperature range. Naturally, the burner can be controlled to be maintained.

In order to minimize the temperature variation of the oil filled between the inner and outer walls of the container 11, the oil is circulated through the conduit 31 which communicates the upper and lower spaces between the inner and outer walls of the container by the pump 30, thereby It can also heat uniformly.

A cover 13 that can be opened and closed is installed at an upper portion of the container 11, and a hydraulic motor 40 is installed at one side of the cover, and an output shaft thereof is an upper end of the shaft of the agitator 14 and a gear biting method installed at the center of the cover. The stirrer is rotated by a hydraulic motor so that the melted resin and pigment components in the container are uniformly melt mixed.

A discharge port 50 is formed at the lower end of the container 11 to discharge the molten paint therein, and an opening and closing plate 51 for opening and closing the discharge port is disposed, and the opening and closing plate is a lever operated manually by an operator. It is connected to the edge part of 52, and it is made to move the said opening and closing board to the upper discharge opening position and the lower closing position. In addition, although the flow of the molten paint discharged through the outlet 50 is not shown in the drawings, a ramp 53 is provided to guide the storage chamber for fusion of the paint on the road surface. Opening and closing plate and lever and ramp configuration for opening and closing the outlet itself is known.

According to the present invention, the paint components are melted without changing the physical properties by indirect heating by oil as a heating medium filled in the double wall structure of the paint melting apparatus and the space therebetween for the painting work on the road lanes, and the temperature. The automatic control of the burner by the sensor keeps the molten paint at a constant temperature at all times, thus eliminating the problem of injury to the operator due to property changes due to local overheating and explosion of the container in the conventional paint melting container. Has the effect of improving the quality of lane coating.
