Abstract

The utility model relates to a plastic storage tank for rotational moulding, including having the staving of storing the chamber, there are many strengthening ribs along the longitudinal distribution of staving on the outer wall of staving, and every strengthening rib is outwards salient and around the peripheral formation of staving from the outer wall of staving, and each strengthening rib is solid plastics structure. The reinforcing ribs of the solid plastic structure can ensure certain thickness and strength, and the bearing capacity of the plastic storage tank can be effectively improved through the plurality of reinforcing ribs distributed along the longitudinal direction.

Description

Plastic storage tank for rotational molding

Technical Field

The utility model relates to a plastic storage tank used in rotational molding process.

Background

The rotational molding process needs to use a storage tank to store molten liquid polymer, the reinforcing rib strength of the plastic storage tank used in the industry at present is insufficient, and particularly, the large plastic storage tank is easy to expand and deform after being filled with liquid medium.

The solution currently in use in the field is to add a sheath of carbon steel or stainless steel around the plastic tank, but the carbon steel sheath has the problem of corrosion contamination, while the stainless steel sheath is too expensive and unacceptable to the manufacturer.

Disclosure of Invention

The utility model aims at providing a plastic storage tank for rotational moulding can guarantee the intensity of storage tank, can reduce the cost of manufacture again.

In order to achieve the above purpose, the utility model adopts the technical scheme that: the utility model provides a plastic storage tank for rotational moulding, includes the staving that has the storage chamber, has many strengthening ribs along the longitudinal distribution of staving on the outer wall of staving, and every strengthening rib is outwards protrusion and is formed around the periphery of staving from the outer wall of staving, and each strengthening rib is solid plastics structure. The reinforcing ribs of the solid plastic structure can ensure certain thickness and strength, and the bearing capacity of the plastic storage tank can be effectively improved through the plurality of reinforcing ribs distributed along the longitudinal direction.

In a preferred embodiment, each reinforcing rib is formed by plastic foaming, so that the process is simple and the manufacturing cost is low.

Further, many strengthening ribs are on the outer wall of staving along the longitudinal distribution of staving with equidistant mode better, equally divide the pressure of staving for the holistic intensity of storage tank is more outstanding.

Preferably, the reinforcing rib is made of polyethylene plastics, is easy to foam and mold and has low cost.

Because of the application of the technical scheme, compared with the prior art, the utility model has the following advantages: the reinforcing rib with the solid plastic structure is used for improving the bearing strength of the storage tank, is low in cost and is easy to accept by manufacturers.

Drawings

Some specific embodiments of the present invention will be described in detail hereinafter, by way of illustration and not by way of limitation, with reference to the accompanying drawings. The same reference numbers in the drawings identify the same or similar elements or components. Those skilled in the art will appreciate that the drawings are not necessarily drawn to scale. In the drawings:

FIG. 1 is a schematic side view of a plastic reservoir in accordance with the present invention;

FIG. 2 is a top view of the reservoir shown in FIG. 1;

wherein the reference numerals are as follows:

1. a barrel body; 2. and (5) reinforcing ribs.

Detailed Description

The technical solution of the present invention will be described clearly and completely with reference to the accompanying drawings, and obviously, the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be obtained by a person skilled in the art without making any inventive step, based on the embodiments described below, belong to the scope of protection of the present invention.

In conjunction with the embodiment shown in fig. 1-2, the main body of the tank is composed of a barrel body 1 and an upper cover (not numbered), and the barrel body 1 has a storage chamber therein for storing molten plastic liquid.

Staving 1 is the plastics material, when a large amount of storage liquid medium, because staving 1 self intensity is not enough, the deformation easily takes place, consequently the utility model discloses based on seek to solve this problem, provided the scheme of taking shape strengthening rib 2 on 1 outer wall of staving.

As shown in FIG. 1, a plurality of reinforcing ribs 2 are longitudinally distributed on the outer wall of the tub body 1, and in the illustrated preferred embodiment, the plurality of reinforcing ribs 2 are distributed in an equally spaced manner.

The reinforcing ribs 2 are preferably formed by foaming polyethylene plastic, protrude outwards from the outer wall of the barrel body 1 and surround the periphery of the barrel body 1, and the formed reinforcing ribs 2 are of a solid plastic structure.

The solid reinforcing ribs 2 greatly improve the strength of the storage tank, and can effectively prevent the deformation of the barrel body 1 when liquid media are stored in the barrel body 1. The foamed plastic is inexpensive to construct and is readily accepted by manufacturers.

The above embodiments are only for illustrating the technical conception and the features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and to implement the same, so as not to limit the protection scope of the present invention, and all equivalent changes or modifications made according to the spirit of the present invention should be covered within the protection scope of the present invention.
