The centrifugal separator included in the present invention is a known component for separating carbides suspended in oil by a difference in particle size or specific gravity, and a cylinder 10 for separating carbides from the oil by centrifugal force, carbides. It consists of a hopper 11 for discharging the discharge pipe 12 for discharging the oil from which this carbide is excluded.

The cylinder 10 has an inlet 10a through which oil, which is a thermal medium, flows in a tangential direction, and a vortex space 10b for separating carbide from the oil introduced through the inlet 10a by centrifugal force. It is formed inside.

At this time, the inlet (10a) is formed in the tangential direction on the side wall of the cylinder 10 to cause the vortex of the oil, the oil introduced into the cylinder 10 through the inlet (10a) is a vortex space (10b) ), And the carbide is separated by centrifugal force during the turning of this oil.

The hopper is formed at the bottom of the cylinder 10 so as to discharge the carbide separated from the oil by centrifugal force to share the vortex space 10b.

That is, the carbide separated from the oil due to the difference in particle size or specific gravity gradually falls along the inner wall of the hopper 11 due to the centrifugal force generated by the vortex of the oil, and gradually falls to the outlet 11a, and finally the carbide separator ( 40).

Therefore, the hopper 11 is formed integrally with the cylinder 10 in a shape that becomes narrower gradually toward the bottom for easy discharge of the carbide, or to form after combining separately.

The discharge pipe 12 is coupled to one end to the cylinder 10 to communicate with the vortex space (10b), and the other end is exposed to the outside to discharge the reversely rising oil.

Here, the discharge pipe 12 is bent in a curved shape so that the other end exposed to the outside is in a straight line with the inlet (10a), it is easy to circulate the oil through this.

In addition, a flange is formed at the other end of the discharge pipe 12 and the inlet 10a of the cylinder 10, respectively, to provide ease of pipe connection.

Therefore, in order to prevent the temperature from dropping in the filtration process of the oil, it is necessary to attach the heat insulating cover 13 or the heat insulating material 14 to the surface of the centrifuge to keep it warm. In this case the attachment of the thermal cover 13 or the thermal insulation material 14 is optional.

The vane 20 included in the present invention guides the oil introduced through the inlet 10a to guide the vortex phenomenon.

To this end, the vane 20 is composed of a body 21 which rotates by coupling to one end of the outlet 11a and a pair of wings 22 formed around the body 21, as shown in FIG. As an example, when the oil is introduced, the wing 22 is rotated along the trunk 21 to guide and pivot the oil.

Therefore, as the vane 20 is installed in the vortex space 10b, the oil introduced into the vortex space 10b is prevented from stagnating, thereby allowing the smooth vortex phenomenon to be continuously performed.

Blocking film 30 included in the present invention is installed on the vortex space (10b) is separated from the oil to block the floating of the carbide accumulated in the outlet (11a), on the contrary, the oil is discharged to the discharge pipe (12) To form.

That is, the blocking film 30 is installed to cross the vortex space 10b to separate carbide from the oil and accumulate in the outlet 11a while blocking it from being remixed with the oil and discharged.

In addition, the conical guide portion 31 is formed on the blocking film 30 to form an upward airflow. Due to the formation of the upward airflow, the oil turns in the vortex space 10b and then reversely rises to discharge pipe 12. Is discharged.

As shown in FIG. 3, the upward airflow formed in the guide part 31 is significantly separated from the outlet 11a where carbide is deposited, unlike the upward vortex naturally formed in the centrifuge, so that the influence on the carbide is minimal. .

Carbide separator 40 included in the present invention is coupled to the lower portion of the hopper 11 to collect the carbide discharged through the outlet (11a), preferably by using a flange.

The carbide separator 40 collects and stores the carbide separated from the oil, and when the amount exceeds the limit, the carbide separator 40 separates and cleans the oil from the hopper 11, and removes and cleans the oil through the carbide separator 40. Driving disorders can be prevented without replacement.

Preferably, the differential pressure gauge 41 is installed in the carbide separator 40 and the pressure gauge 10c is installed in the cylinder so that the amount of carbide collected can be measured, and the pressure of the pressure gauge 10c and the differential pressure gauge 41 is increased. By measuring the difference from time to time to measure the collection amount of carbide, if the collection amount exceeds the limit is to remove the carbide separator 40 from the hopper 11 to clean.

In order to prevent the oil from being discharged in the separation process of the carbide separator 40, the present invention includes an on-off valve 50, the on-off valve 50 is usually opened the outlet (11a) and then the carbide separator ( The outlet 11a is closed when the 40 is separated.

The on-off valve 50 is an embodiment of the check valve to prevent the reverse discharge of the carbide collected in the carbide separator 40.

Therefore, according to the present invention, the carbide separator 40, the blocking membrane 30, and the vane 20 including the open / close valve 50 may be semi-permanently used through separation and removal of carbides. Maintenance of the heating system 100 using oil as the heat medium is made possible at low cost.

As a result of being delayed by the refraction-tube 4c in the process of conveying along the circumstance, driving obstacles due to rapid natural emission are eliminated.

The oil supplement tank 4 is connected to an expansion tank 3 for maintaining a proper level of water to supply oil to the heating vessel 2 and to transfer oil heated by the electric heat heater 2a. The circulation pump 5 forms a pressurized pressure by driving through a conventional motor M to supply the oil in the expansion tank 3 to the heating vessel 2, and passes through the heating vessel 2. The heated oil is transferred to the entire heating system 100.

The circulating pump 5 is installed at the lower part of the main body 60 together with the motor M to be started by way of example. When there are several heating containers 2 installed in the main body 60, each heating container is provided. It is connected in parallel with (2) to supply oil.
