The present invention relates to a fuel agitator heating apparatus for ships, and more particularly, welding and fixing a vortex collision plate having a plurality of serrated acute grooves in a heating tank, and combining several magnets with the vortex collision plate, and the end of the rotating shaft. By combining the centrifugal impeller to the part, and relates to a fuel agitator heating apparatus for ships that can supply a high-quality fuel oil to the engine by pulverizing and grinding the solids contained in the fuel oil more finely.

In general, ships tend to be large, high speed, and high output as international competitiveness is strengthened, and fuel oil uses low-priced heavy oil.

Bunker A and Bunker C of the ship fuel oil are not suitable for direct use in the main engine, and are selectively mixed with various additives.

Low-grade fuel oils and additive mixtures (hereinafter referred to as 'fuel oils') require a process to improve their properties before being transferred to the fuel injection pump of the main engine.

In the process of improving the properties of the fuel oil, the fuel oil heated first is supplied to the main engine via the service tank and the settling tank.

However, since the temperature of the fuel oil is gradually lowered while the fuel oil heated in the service tank is transferred to the main engine, the viscosity of the fuel oil cannot be maintained.

In addition, there is a problem that does not provide a device for circulating, heating the fuel oil supplied to the service tank, there is a problem that does not increase the temperature of the fuel oil stored in the service tank and the settling tank to stay.

In addition, when the heating coil of the tube type heater generates heat and rises to a high temperature, impurities contained in the fuel oil are carbonized and deposits accumulate. As a result, the inside of the tube is blocked and the circulation of the fuel oil is not performed smoothly. Alternatively, the consumption of electricity is reduced to lower the efficiency of the heater, and the carbonized deposit promotes abrasion of moving parts such as pumps, valves, and nozzles, thereby causing engine failure. In other words, the combustion state of the engine is worsened by wax or moisture contained in fuel oil or solids such as dry sludge such as iron rust, sand and minerals, which may cause wear of the cylinder liner, damage and blockage of the fuel injection valve. There was a problem.

Applicant of the present invention is to solve the above problems, "fuel fuel heating device for ships" of the Republic of Korea Patent No. 10-0485253 and "fuel fuel heating device with a filter formed" of the registration room No. 20-0395799 and No. 20- 0396124 was invented a "fuel stirred vessel heating device with a filter".

That is, a fuel inlet having a valve and a fuel outlet and a fuel circulation port are formed in a cylindrical heating tank in which a plurality of stirring plates are formed, and a cover having an air valve and a pressure gauge is formed on the upper side of the heating tank to be combined with the heating tank by fixing bolts. And coupling a heating heater having a power supply to the inside of the heating tank, connecting the pulley of the motor to the pulley formed on the shaft so that the impeller can be driven by the driving of the motor, and smoothly rotating the shaft to the outside of the shaft. Characterized in that the bearing case is formed with a packing and a bearing to maintain the airtightness of the heating bath;

By heating and stirring the primary heated mixed oil again in the service tank, it maintains the temperature of the fuel stably, prevents the formation of carbides deposited on the heater surface, and generates the main fuel generated by supplying low-temperature fuel to the engine. It is possible to extend the life of the main engine by preventing the engine failure, and to minimize the fuel cost by operating the main engine with fuel oil mixed with high-grade fuel and low-grade raw materials.

However, in the stirring heating device invented by the applicant of the present invention, the impeller having a shape in which a substantially triangular wing is erected perpendicularly in parallel with the axial direction of the shaft stirs the fuel oil strongly toward the inner circumferential surface of the heating bath due to its structure. Without knowing, the stirring plate is welded to several places in the form of small pieces inside the heating bath, there was a problem that can not effectively crush high viscosity sludge.

The present invention has been made to solve the above problems, in order to optimize the combustion by miniaturizing the solids contained in the fuel oil used in the engine, a plurality of inside the heating tank of the stirring heating device was proposed by the applicant of the present invention Weld and fix the vortex colliding plate with the sawtooth acute groove, couple the magnets to the vortex colliding plate, and combine the centrifugal impeller to the end of the rotating shaft, thereby finely crushing and grinding the solids contained in the fuel oil. It is an object of the present invention to provide a fuel oil stir heating device for ships that can supply high quality fuel oil to an engine.

The configuration of the present invention will be described in more detail together with the stirring heating process of the fuel oil.

The fuel oil of the service tank is supplied into the heating tank 10 through the inlet pipe 13 by the operation of the pump.

The temperature of the fuel oil inside the heating tank 10 is increased by the heating coil 81 of the heater 80, and the impeller 51 is rotated to give a speed energy to the mixing and progress of the fuel oil.

When the impeller 51 rotates at a high speed, the flow of fuel oil inside the heating tank 10 is strongly hit by the vertical vortex colliding plate 30 vertically installed by the high speed vortex. In addition, the fuel oil is strongly hit against the vortex impact plate 20 welded horizontally.

At this time, the fuel oil strongly radiated and vortexed by the impeller 51 collides with the vortex collision plates 20 and 30 and passes through a plurality of tooth-shaped acute grooves 21 and 31 to finely grind the solids contained in the fuel oil. , Is ground.

The centrifugal impeller 51 is a device for generating high speed vortices for sludge crushing and grinding of fuel oil. The high speed vortex is rotated at a constant speed under constant pressure (1.5 to 2.0 kg / cm 2) for high speed agitation. Create

The high velocity vortex fuel oil flow prevents solids from carbonizing and depositing on the surface of the heating coil inside the stirring heater.

The flow of fuel oil made by the impeller 51 proceeds by forming a rapid vortex from the upward direction to the downward direction, and the fuel oil is several vortex collision plates 30 vertically installed vertically inside the heating tank and vortices installed directly below.
