Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a method of assembling a storage tank,

The present invention relates to a method of assembling a storage tank for plant construction, and more particularly, to a storage tank assembly for a plant construction capable of easily and easily assembling and installing a storage tank constituting a plant, ≪ / RTI >

A plant is a production facility capable of manufacturing raw materials, intermediate materials, and final products intended for producers by technically installing mechanical devices and various facilities such as power plants and oil refineries. It is used for engineering / procurement / construction Construction is a complex industry, which has a high effect on industrial relations and contributes to the advancement of industrial structure.

Generally, a plant is classified into a chemical plant, a food plant, and a pharmaceutical plant. Such a plant is generally used in a petrochemical industry, a catalytic chemical reaction of methanol and ammonia, A storage tank in the form of a container in which the chemical reaction can proceed through stirring, contact heating, or the like while flowing, and a condenser for cooling and liquefying the gas using sensible heat of the cooling water A water separator connected to the condenser and capable of separating cooled water and oil, and a meter for measuring a content of the contents of the storage tank which can cause a chemical reaction and supplying the water to a predetermined amount.

Generally, a plant having such a structure is manufactured at a separate factory and then transported to the site and then assembled.

For example, a storage tank may be installed in the field, and then a meter may be provided to supply a certain amount of content into the storage tank. A condenser is installed on one side of the storage tank, and the storage tank and the condenser are connected by using a connection pipe.

Thereafter, an oil-water separator for separating water and oil cooled in the condenser is installed, and the condenser and the oil water separator are connected to each other using a separate pipe, and the oil water separator and the storage tank are connected to each other. Complete.

However, conventionally, it has been disadvantageous in that it is difficult to align the storage tank at the time of installation of the plant.

Specifically, in order to effectively induce the chemical reaction of contents in the storage tank, a mixer is usually installed. In this case, when the mixer is not located at the center of the storage tank, there is a disadvantage that the mixer rotates and uneven vibration and noise are generated. Thereby causing the storage tank to be damaged.

Therefore, it is very important to level the storage tank in the construction of the plant, and the time required for the operation is also getting longer.

1 is a view schematically showing a conventional method of assembling a storage tank.

However, in the case of the storage tank 1, since the mixer 40 is located inside the mixer 40, the mixer 40 can be easily assembled and assembled, There was a severe discomfort.

That is, in the conventional storage tank 1, the lower housing 10, the upper housing 20 assembled to the upper portion of the lower housing 10, and the upper housing 20 installed on the lower housing 10 The conventional storage tank 1 typically includes a mount 30 connected to the upper housing 20 and a mount 30 connected to the mount 30. The mount 30 is mounted on the upper housing 20, The upper housing 20 coupled to the lower housing 10 is assembled with the storage tank 1 in such a manner that the upper housing 20 is coupled to the lower housing 10.

At this time, the mount 30 should be level with respect to the upper housing 20 such that the mixer 40 is positioned in the lower housing 10 when the upper housing 20 and the mount 30 are engaged. That is to say, since the mixer 40 is fixedly coupled to the mount 30, the operation of aligning the upper housing 20 and the mount 30 is performed so that, during rotation of the blades 40 of the mixer 40 in the lower housing 10, You should minimize noise and vibration.

1A, the upper housing 20 is placed on the upper surface of the large table 2, and then the upper surface of the upper housing 20 is welded to the upper surface of the upper housing 20. As shown in FIG. After mounting the upper housing 20 and the mount 30, the horizontal bar 3 is placed on the upper portion of the mount 30 and the height of the left and right sides of the base 2 and the horizontal bar 3 is measured. 30 and the upper housing 20, the mixer 40 is assembled to the mount 30 as shown in FIG. 1B.

That is, in a state where the mount 30 and the upper housing 20 are in contact with each other, the horizontal level is measured using the horizontal bar 3 and the surface plate 2, and if the level is not horizontal, the welded portion is removed, Since the mount 30 and the upper housing 20 are aligned with each other in such a manner that the mount 30 and the mount 30 are rotated, the operation is inconvenient and troublesome.

Even if the upper housing 20 and the mount 30 are aligned horizontally as described above, when the upper housing 20 and the lower housing 10 are later assembled, the mixer 40 is not tilted And the blades of the mixer 40 are positioned so as to be inclined in the lower housing 10 as a result.

Accordingly, the present applicant has proposed a method of assembling a storage tank for constructing a plant in order to solve the above-described conventional problems.

According to one aspect of the present invention, in constructing a plant, it is possible to quickly and accurately assemble a storage tank for easily and horizontally aligning the storage tank, thereby reducing the overall operation time due to plant construction. The present invention relates to a method of assembling a storage tank.

That is, by allowing the four positioning cylinders 180 to be driven simultaneously with the inner diameter of the mount 30, the transfer block 174 can be positioned in the center of the inner diameter of the mount 30.

In addition, the rod end of the position adjusting cylinder 180 is provided with a contact member 182 having a convex outer circumferential surface so that accurate contact can be made when the inner circumferential surface of the mount 30 is contacted.

In the case of the horizontal cylinder 170 supporting the transfer block 174, the vertical column member 160 is fixed to the vertical column member 160. However, in the case of the vertical column member 160, The length of the position adjusting cylinder 180 may be increased or decreased in a process in which the four position adjusting cylinders 180 are driven to be positioned at the center of the inner diameter of the mount 30.

Meanwhile, a measurement member 190 is installed on one side of the front surface of the transport block 174.

The measuring member 190 irradiates a beam to determine whether the center of the mount 30 mounted on the seating member 150 coincides with the center of the housings 10 and 20. [

5, a beam irradiated in a state in which the measuring member 190 is positioned inside the mount 30 passes through the center of the mount 30 and is provided with a sensor (not shown) mounted on the housing So that the mount 30 and the housing can be in a horizontal state, and then the mount 30 and the lower housing 10 are assembled.
