Description

COAL TAR INJECTION DEVICE}

The present invention relates to a coal tar injector, and more particularly, to an injector for injecting coal tar on a road surface at all stages of road pavement, which can freely adjust the width of the spray of coal tar and operate as a separate engine to control the speed of the vehicle. Regardless of the present invention, it is possible to control the amount of spraying of coal tar, and after the use of the spraying apparatus, a coal tar spraying apparatus capable of performing circulation washing in the apparatus to prevent the coal tar from solidifying in the spraying apparatus.

In general, in order to make a road suitable for driving of vehicles, materials such as coal tar and gravel extracted from crude oil are mixed in an appropriate ratio to the upper side of the road, coated with ascon, pressurized with a roller, and naturally cooled and dried.

As a result, the paved asphalt road will run out of asphalt for a certain period of time, resulting in cracks or rough roads. It was.

As described above, when resurfacing the road surface, in order to improve the adhesion between the existing road surface and the asphalt concrete applied, after coating the coal tar on the road surface, the asphalt road was coated and pressed to form the road surface.

As described above, the conventional coal tar injector applying the coal tar before repairing the road surface is stored in a tank in a solid state, heated and melted, and then sprayed through the injector with the driving force of the automobile engine.

However, in the conventional coal tar injector as described above, since the driving force of the injection pump for injecting uses an automobile engine, when the inclined road or the speed of the vehicle is increased and the engine is heavily loaded, the injection volume of the coal tar is increased and the engine load is small. At that time, the amount of spraying was small and it was difficult to spray a certain amount of kool tar on the road surface.

In addition, since the coal tar is hardened at room temperature, it is necessary to clean the coal tar remaining in the pump or peripheral device after using the coal tar injector so that the device can be used for a long time. Repeatedly have to be cleaned several times.

Therefore, after spraying the coal tar, it is possible to clean only by using a large amount of diesel oil, which resulted in a large amount of diesel oil loss, and was also a major cause of environmental pollution. There is a problem in that the life of the injector is reduced because the perfect cleaning is not made because the device is cleaned in the same manner as the spraying of the coal tar instead of air or other methods.

Therefore, the present invention has been made in view of the problems of the prior art as described above, by spraying the coal tar by the driving of a separate engine, it is possible to inject a certain amount and the width of the injection of the coal tar can be freely adjusted as well as a small amount The purpose of the present invention is to provide a coal tar injector that can extend the life of the injector by circulating the diesel oil through the compressed air in the injector and cleaning it to remove perfect coal tar.

In order to achieve the above object, the present invention forms a storage tank for storing the coal tar by forming an inlet on the upper side and a heating unit having an inlet pipe for injecting fuel from the heating fuel tank to the lower side of the storage tank. A preheating part formed with a formed tank part and a torch lamp for forming a torch insertion hole above the inlet pipe to vaporize fuel flowing through the inlet pipe to the outside of the heating part of the tank part and preheating it with a separate fuel; The coal tar inflow pipe connected to the storage tank is connected to one side to be heated by the heating unit preheated in the unit so as to introduce the liquid tar into the tank, and the coal tar flowing from the storage tank is discharged to the lower side. A coal tar outflow pipe is formed so that the cleaning oil inflow is introduced on the other side from the cleaning oil tank. And the back side forms a compressed air inlet pipe for introducing compressed air, and the upper side of the inlet valve is formed with a handle, and the coal tar outlet pipe of the inlet four-way valve is connected to the coal tar outlet pipe by the pumping action to extrude the raw material and outflow And a driving unit configured to transfer driving force to the emulsion pump through an engine that receives fuel from a fuel tank and generates a driving force for driving the emulsion pump, and a transmission that reduces driving force of the engine. In order to inject the coal tar extruded from the emulsion pump driven by the driving force of the injection inlet pipe connected to the emulsion pump is formed on one side and the injection outlet pipe in the rear and the valve connected to the storage tank of the tank in the upper side A circulation pipe is formed and a manual spray hole is formed and the other side is opened and closed by a hydraulic cylinder. The injection-connecting valve having a handle and an injection-connecting valve formed with an opening / closing valve which is opened and closed by a hydraulic cylinder so as to be sprayed with a liquid coal in order to be sprayed with the injection-outlet pipe of the discharge-return valve; On the lower side, a plurality of injection nozzles are formed on both sides to form a folding port, and the injection portion formed by the injection pipe for spraying the coal tar evenly on the road surface, and the injection pressure of the coal tar sprayed through the injection portion is high. In this case, in order to control the injection pressure, it provides a coal tar injection device comprising a feedback unit formed by connecting the connection pipe formed with a pressure control valve to the injection outlet pipe of the outflow four-way valve and the coal tar outlet pipe of the inlet four-way valve. .

Therefore, the device can be cleaned thoroughly with a small amount of gas, and the injection volume can be kept constant, thus increasing the reliability and efficiency of the product.
