Abstract

The present invention is a sink roll (SINK ROLL) is driven in the tank containing the solution is driven by a motor installed outside the tank (TANK), the sink roll (SINK ROLL) while rotating or at rest To prevent quick leakage (assembling of water, hydrochloric acid, phosphoric acid, chromic acid), corrosion and damage of sink roll, and quick dismantling and assembly work when replacing mechanical seal (3 months available for mechanical seal) The seal unit is designed.

In more detail, when assembling the SINK ROLL, the tank is assembled as a single unit (roll, seal unit, bearing unit), rather than individual assembly work, and is quickly and easily assembled in the tank TANK.

Its composition consists of assembling and disassembling the seal unit completely on the sink roll by changing the size of the flanges on both sides, and disassembling and disassembling it on the tank. The small part is a device that machined the inner surface of the tank and seals it using a ring (RING 1) and a gasket (GASKET 3).

Description

Sealing device for sink roll

The present invention relates to a sealing device for a sink roll.

Cold rolling equipment can reduce cost and increase product output depending on how much the maintenance time is shortened. Conventional techniques include corrosion of sink rolls, rubber damage on roll surfaces, and mechanical seals. SEAL) When replacing the roll unit after 3 months of use, dismantle and assemble the parts assembled in the sink roll (cuffing, flange, ring, mechanical seal) in a narrow place. Therefore, it is a cause of safety accidents due to excessive time spent and unsafe work.

The procedure of a conventional dismantling operation is briefly described as follows.

1) Disassemble the COUPLING bolts and separate them.

2) Remove the bearing housing cover and remove the bearing housing from the sink shaft.

3) Loosen the bearing nut and take out the self-aligning bearing.

4) Loosen the mechanical seal fixing bolt and take out the mechanical seal.

5) Pull out various flanges from sink roll.

6) Take out SINK ROLL from tank by using JIG.

Assemble work after disassembly in the reverse order of dismantling

In this case, the time required for disassembly and assembly is about 2 hours, resulting in a high production cost.

Accordingly, the present invention solves the above problems by changing the hole size of both flanges of the tank and allowing the fully assembled sink roll to be connected to the flange of one side of the seal SEAL. It was possible to assemble inside the tank (TANK).

In this way, all the parts assembled in the sink roll are assembled from the outside and then assembled in the tank TANK to complete all the work.

(SINK ROLL is always ready for replacement and is replaced frequently)

In this case, it takes about 0.5 hours to dismantle and assemble, contributing to cost reduction.

In order to solve the above problem, assembling the sink roll (SINK ROLL) integrally by changing the arrangement and fixing method of the sealing unit (SEALING UNIT) is characterized in that the assembly to the tank (TANK).

EXAMPLE

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

1 is an overall assembly view of the present invention is assembled.

2 is a detailed view of a sealing unit.

(1) RING, (2) GUIDE FLANGE, (3) (9) (10) (13) (14) GASKET for quick replacement and sealing And (4) MECHNICAL SEAL, (5) CAP, (6) (7) (8) (11) (15) BOLT, (12) FLANGE.

The seal unit arrangement is to prevent the liquid in the tank from leaking out when the SINK ROLL contained in the tank TANK is driven as shown in the schematic.

It is not necessary to assemble and disassemble the seal unit in the state assembled in the tank, which can shorten the maintenance time and increase the product yield.

Claims (1)

In a cold rolling facility, a sink roll driven in a tank containing a solution is driven by a motor installed outside the tank, and the sink roll prevents leakage of a solution (water, hydrochloric acid, phosphoric acid, chromic acid) during rotation or stoppage, and a sink roll. The ring 1 is coupled to the guide flange 2 so as to facilitate replacement by preventing corrosion and breakage, and quick disassembly and assembly work when replacing the mechanical seal, and the gasket 3, 9 and 10 (13) (14), mechanical seal (4), cap (5), bolt (6) (7) (8) (11) (15), flange (12), seal unit is sink in tank Sealing device for sink roll, characterized in that the liquid in the tank does not leak out when the roll is driven.
