Description

Insulation coating solution supply device {INSULATION COATING LIQUID SUPPLYING DEVICE}

The present invention relates to an improved insulating coating solution supply device to store a predetermined amount of the insulating coating solution to supply smoothly without clogging to the insulating coating equipment.

In general, the high viscosity insulating coating solution has a strong viscosity, and is supplied by pumping to a coater (COATER), which is an insulating coating facility, through a delivery line with continuous stirring.

Conventionally, as shown in FIGS. 1 and 2, the hydraulic line 2 is installed on one side of the upper portion of the tank 1, and the coating solution primarily used in the facility is installed in the tank 1 through the hydraulic line 2. The floating material (A) that is floated by the outer cap 6 protruding higher than the upper surface of the tank 1 is blocked, and the coating solution is connected to the inside of the outer cap (6) After moving to the space with the inner cap (4) fixed by the (5) is introduced into the inner cap (4) through the solution inlet (4a) formed in the inner cap (4), then the screen net (8) It is configured to be discharged via the delivery line (3) through.

However, since such devices are foreign substances generated by peeling off the surface of the strip during coating operation, such as non-floating oxide scales, they are not completely filtered, so that these oxide scales together with the solution may cause the inner cap 4 and the screen net 8 to be removed. After being discharged to the facility, the surface of the beautifully coated rubber coating roll is damaged, and of course, the coating surface of the strip is rough.

In addition, the closure of the screen net 8 brings about the congestion of the solution in the space between the inner cap 4 and the outer cap 6, resulting in delayed operation, as well as the coagulation material formed therebetween. Supplying to the side is caused a disadvantage that causes another product failure.

The present invention was created in view of the above-described problems of the prior art as described above, and provided with a flowable means in the inner portion of the tank in which the insulating coating solution is accommodated to prevent stagnation of the solution, as well as It is an object of the present invention to provide an insulation coating solution supply device which can further improve the beauty of the coating surface by cutting and crushing a relatively long coagulation material.

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

3 is a partial perspective view of a supply apparatus according to the present invention.

According to FIG. 3, a plurality of supports 12 are extended upwardly in an approximately triangular shape at the upper outer circumferential surface of the tank 10, and a driving motor 14 is fixed to an extended vertex of the support 12.

The rotating shaft 16 of the drive motor 14 is extended downward, and the horizontal connecting rod 20 is connected and fixed in a direction orthogonal to the rotating shaft 16 at its end.

Both ends of the horizontal connector 20 is fixed in the radial direction and the inner surface of the ring-shaped rotating plate 22.

A wave shaped wave guide 24 is formed on the bottom surface of the rotating plate 22, and the wave guide 24 has a substantially '∩' shape as described below, and both sides of the bottom face each other. It is preferable to zoom so that the bent end is vertically bent again in the upward direction and then the guide roller 26 coupled thereto is not easily detached.

The rotating plate 22 is seated on the top surface of the filtration cylinder 30 supported and fixed by the support plates not shown inside the tank 10.

The upper end surface of the filtration cylinder 30 is maintained in a circumferential shape in the circumferential direction of the wave form similar to the wave guide portion 24 of the rotating plate 22 is not formed at all, thus the rotating plate 22 The rotation of) causes a periodic gap with the bottom surface of the rotating plate 22 over time at any one of the top surfaces of the filtration cylinder 30.

On the other hand, the filtration cylinder 30 is a double pipe in the hollow portion which is a space between the outer tube and the inner tube, a plurality of flow shafts 40 are spaced up in the vertical direction at regular intervals along the circumferential direction.

In addition, a plurality of outlet holes 32 are formed on the outer circumferential surface of the filtration cylinder 30, and a delivery line D is connected to the lower surface of the inner tube.

Figure 4 is an exploded perspective view of the main portion of the supply apparatus according to the present invention, the flow shaft 40 is installed in the hollow of the filtration cylinder 30 so as to flow up and down, the bottom surface of the hollow 'U' shape The case 42 is fixed, and the case 42 has a spring 44 embedded therein, and a lower end of the flow shaft 40 is fitted in the direction in which the spring 44 is pressed.

The upper end of the flow shaft 40 is exposed to the outside through the upper end of the filtration cylinder 30 and then welded to the horizontal support 48, the both ends of the horizontal support 48 to the wave guide portion 24 A pair of guide rollers 26 which are movable while being in contact with the cloud is coupled.

In addition, a plurality of curved cutting edges 46 are formed on the longitudinal outer circumferential surface of the flow shaft 40 at intervals corresponding to the plurality of outlet holes 32 formed in the filtration cylinder 30.

In addition, a screen net 50 is attached to the inner circumferential surface of the inner tube of the filtration cylinder 30 to seal the outlet holes 32 with a predetermined mesh.

The present invention made up of such a configuration has the following operational relationship.

When the solution flows into the tank 10 and is filled, the solution moves to the inner tube side of the filtration cylinder 30 through the outlet hole 32 to filter relatively large solids in the solution through the screen network 50.

The filtered solution is sent to the installation side performing the subsequent process through the delivery line (D).

When agglomerated solids are grown in the hollow part of the filtration cylinder 30 by contact with air and entanglement of solids in the circulation process by prolonged use, the operator drives the driving motor 14.

The drive motor 14 may be set to be periodically operated by a timer facility, or may be selectively used whenever necessary by manual operation.

When the driving motor 14 is driven to rotate the horizontal plate 20 is connected to the rotating shaft 16, the rotating plate 22.

At this time, since the wave guide portion 24 of the rotating plate 22 is formed in a concave-convex shape, the upper end of the flow shaft 40 of the spring 44 when the valley and the floor of the wave guide portion 24 intersect. It is made to flow by elastic force.

That is, while being elastically operated in the vertical direction in the hollow portion of the filter cylinder 30 is vibrated in proportion to the rotational speed of the rotating plate (22).

In this process, the curved cutting blade 46 installed in the longitudinal direction of the flow shaft 40 is finely cut and crushed solids in the hollow portion.

As a result, the growth of solids is suppressed and crushed to eliminate the blockage, so that the inflow and outflow of the solution is maintained smoothly.

As described in detail above, according to the present invention the following effects are expected.

First, the filtration of the solution inhibits the growth of solids to improve the flowability of the solution.

Secondly, it has excellent filtration efficiency to prevent poor coating.

Thirdly, since poor coating is prevented, product quality is improved and productivity is improved.
