Description

TECHNICAL FIELD [0001] The present invention relates to a prefabricated plastic container for fluid storage and a method of manufacturing the same,

The present invention relates to a prefabricated plastic container for fluid storage, and in particular to a method of making prefabricated plastic containers.

Containers that store large volumes of fluids such as water, oil, etc. are mostly composed of concrete structures. Containers made from such concrete structures are typically formed in a tubular or box-like unitary structure and are exposed to considerable disadvantages in storage and transportation. For example, since containers of concrete structures are integrated, it is necessary not only to rely on heavy trucks but also to consider road conditions during transportation. Roads are equipped with traffic lights, street lights, median strips, and / or road signs for the safety of pedestrians and vehicles, which can be dismantled on roads when transporting large volumes of fluid containers. Then, after the large-capacity fluid storage container has passed, it will be necessary to re-install the dismantled facilities.

Patent Document 1 is disclosed in Korean Patent Laid-Open No. 10-2003-0028503 entitled "Concrete integrated type septic tank structure and assembly set for constructing the above-mentioned septic tank structure and method of construction ", which facilitates easy transportation and construction, And an assembly set for assembling a plurality of segments to each other. It is designed to install the unit type separable assembly form away from the septic tank and to cement the concrete by putting remicon or concrete between the septic tank and the separated assembly form.

Patent Literature 1 is well known to those skilled in the art, as concrete is placed to surround the outside of the septic tank, and even though it can provide ease of transportation and construction, . In addition, since such a septic tank structure is made of concrete, it is not possible to recycle it, and it also takes considerable time and cost in dismantling.

In addition, concrete structures can be a cause of water pollution and there will be a need to apply a separate waterproof layer.

In addition to concrete, a tank of FRP material may be employed. Typically, FRP tanks are vulnerable to durability, which implies the risk of leakage.

In addition, stainless steel tanks have corrosion resistance, but they are expensive materials and corrosion on welds.

Preferably, the front portion 20 is formed in a dome shape with a ring-shaped contact end 21. The ring-shaped contact end portion 21 is formed to correspond to an upper shape of the plurality of unit segments 10 arranged in a cylinder shape, thereby shielding the upper openings of the plurality of unit segments 10. [

In addition, the rear portion 30 is formed in a dome shape having a ring-shaped contact end portion 31. [ The ring-shaped contact end portion 31 is formed corresponding to the lower shape of the plurality of unit segments 10 arranged in a cylinder shape to shield the lower openings of the plurality of unit segments 10.

A plastic container for fluid storage (1) according to the present invention is assembled by arranging a plurality of unit segments (10) in a cylindrical shape. As shown in FIG. 4, the plastic container for fluid storage 1 according to the present invention is assembled into three unit segments 10, but the present invention is not limited thereto, The capacity of the fuel cell 1 can be increased to several tens of tons or more.

3, the unit segment 10 having four faces has an upper face 11, a side face 12, a lower face 13, And the other surface (14). Here, the upper surface 11 refers to a portion that is in contact with the ring-shaped contact end 21 of the front portion 20, or a portion that is in contact with the lower surface of another unit segment when the length of the front portion 20 is extended, Refers to a portion in contact with the ring-shaped contact end 31 of the rear portion 30 or a portion in contact with the upper surface of another unit segment at the time of elongation. For reference, FIG. 3 schematically illustrates the inner and outer walls of a unit segment, which is illustrated in order to provide a clear understanding of the side structure of each unit segment.

At one side end and the other side end, a coupling protrusion 12b and a coupling groove 14a are provided, respectively. The engaging protrusions 12b provided at the end of one side of the unit segment 10 can be fitted and fitted with the engaging groove 14a provided at the other end of the other unit segment 10 adjacent thereto. In other words, the unit segment 10 may have a coupling protrusion and a coupling groove at the side end for assembling with the other unit segment 10 arranged in a cylinder shape, so that each unit segment can be arranged in a cylindrical shape. Incidentally, the engaging projections and the engaging grooves may be formed to be shorter than the length of each side face.

The upper surface 11 of the unit segment 10 can form an engaging groove 11a for receiving the engaging projection 21b formed in the contact end portion 21 of the ring-shaped upper portion of the front portion 20, When the engaging groove is formed in the contact end portion 21 of the ring-shaped upper portion 20, the engaging projection can be formed. This is because a plurality of unit segments 10 arranged in a tubular shape can be inserted into the front portion 20 at a predetermined position, thereby improving the degree of assembly.

Correspondingly, the lower surface 13 of the unit segment 10 is provided with an engaging groove or engagement protrusion (not shown) corresponding to the engaging protrusion or engaging groove 31a provided in the contact end 31 of the ring-shaped upper portion of the rear portion 30 13b.

Referring to the circular arc portion A of FIG. 1, the fluid storage container 1 according to the present invention can confirm the assembled state of the front portion 20 and the unit segment 10. The assembled state of the rear portion 30 and the unit segment 10 has a similar structure to that of the illustrated front portion 20 and the unit segment 10, Will exclude here.

It is preferable that the unit segment 10, the front portion 20 and the rear portion 30 are manufactured by blow molding. As is well known to those skilled in the art, the blow molding process involves injecting a molten preform with air and extruding it to form an opening 50 that facilitates air injection into the preform.

The unit segment 10 to be manufactured by the blow molding method and the front portion 20 and the rear portion 30 can be manufactured by forming the inner wall IW and the outer wall OW in the molding process through air injection into the opening 50 And a chamber 60 is formed between the inner wall IW and the outer wall OW. That is, the inner wall IW and the outer wall OW are formed in a double wall structure, so that the strength can be improved. Furthermore, the plurality of unit segments 10 arranged in a cylindrical shape may further include a partition wall (not shown) on the inner circumferential surface thereof. Such a partition wall can not only divide the large-capacity container 1 into a plurality of compartments, but also can hold the container 1 against the pressure of the fluid to be filled in the container and can reinforce the supporting force of the container. It is possible to increase the structural strength between the unit segment 10, the front portion 20 and the rear portion 30 to be manufactured by the blow molding method and be provided between the inner wall IW and the outer wall OW, Materials can be used to implement various properties.

The inner wall IW and the outer wall OW of the segment 10 and the front portion 20 and the rear portion 30 can be made of different plastic materials, Depending on the type, the inner wall (IW) may be provided with additional functionality and the outer wall (OW) may be formed of a material that is not damaged by an external impact to facilitate transportation or storage.

The opening 50 is also formed in the outer wall OW to aid in the infusion of air which is used to fill the chamber 60 with a flowable material such as a concrete material, Can be used. The thus filled concrete material can secure the structural stability of the plastic container for fluid storage 1 of the present invention.

The unit segment 10, the front part 20 and the rear part 30 to be manufactured by the blow molding method are preferably made of a plastic material. Even if they are buried in the ground, they are used semi-permanently, Can be prevented.

The assembled state in which the unit segment 10 and the front portion 20 are fitted to each other through the concave-convex portion can be confirmed with reference to the circular arc portion A. [ The upper surface 11 of the unit segment 10 has the engaging groove 11a and the contact end 21 of the front portion 20 forms the engaging projection 21b. The engaging projections 21b of the front portion 20 are inserted into the engaging grooves 11a of the unit segments 10 to assist in fixing the positions of the respective constituent members.

In addition, the peripheral wall surfaces of the inner wall IW and the outer wall OW of each of the structural members (the unit segment 10, the front portion 20, and the rear portion 30) form a chamfer (CW). The top surface 11 of the unit segment 10 and the ring top of the front portion 20 arranged in a mutually interlocking arrangement provide a V-shaped groove through each chamfer CW, It is possible to form a welded portion W in the V-shaped groove portion formed in the contact portion to assure a reliable bonding state between the respective constituent members. The present invention is not limited to this, and in order to improve watertightness and durability, a weld W can be formed by welding both inside and outside of each connecting part of one or more segments, the front part and / or the rear part.

As described above, according to the present invention, since each constituent member is coupled with the engaging groove in the engaging manner of the engaging projections, in order to prevent leakage (or leaking) The sealing member S can be further arranged.

FIG. 6 is a cross-sectional view schematically showing an inner wall according to an example of the present invention, wherein the inner wall shown in FIG. 6 corresponds to the inner wall of the segment, the front portion, and the rear portion.

The inner wall IW may have a laminated structure having three layers as shown in the figure. Specifically, the inner wall IW includes a first layer IW-1, a second layer IW-2, and a third layer IW-3.
