Abstract

The utility model discloses a steel plastic composite tank and belongs to the technical field of container tanks. The steel plastic composite tank comprises a tank bottom, a tank wall and a tank top, wherein the tank bottom is rotationally molded with a polythene layer inside a steel plate, the tank wall is composed of steel belts which are twisted into spiral shapes, overlapped parts between the neighboring spiral shapes form a run-resistant slot, convex intensifying ribs are fixed on the outer surface of the steel belts, and polythene layers are arranged on two sides of the steel belts, and the connected parts of the steel belts and the steel plate are fixed together. The steel plastic composite tank has the advantages that steel and plastic on the tank bottom of the tank body are closely combined and are not separated, the tank has high intensity, corrosion prevention, long service life and low cost.

Description

A kind of steel is moulded composite tanks

Technical field

The utility model belongs to container technical field, especially relates to a kind of high capacity steel and moulds compound holding vessel.

Background technology:

The high-capacity corrosive liquid packing container of current China has two kinds, and a kind of is to be the pure tank body of moulding of raw material with the polyethylene, and another kind is to burn-on in the cylinder of steel behind the metal gauze at the storage tank that rolls on one deck plastics with rotational molding technique.The shortcoming of pure plastics storage tank is that intensity is low, yielding; And be the consumptive material height in the shortcoming that rolls on the plastics storage tank with rotational molding technique behind the metal gauze of burn-oning in the cylinder of steel, weight is big, complex process, and poor adhesive force easily comes off, the life-span is short.The phenomenon that metal gauze comes off with plastic layer appears sometimes.More than these problems are difficult problems that current corrosive liquid storage tank is faced.

Summary of the invention

The purpose of this utility model be to improve the deficiency of prior art and provide at the bottom of a kind of jar, the steel of tank skin mould in conjunction with closely do not peel off, intensity height, withstanding corrosion, long service life, steel that cost is low mould composite tanks.

The purpose of this utility model is to realize like this, a kind of steel is moulded composite tanks, by at the bottom of the jar, the tank deck of tank skin and band jar mouth forms, be that the inboard rotational moulding of steel plate has polyethylene layer at the bottom of being characterized in jar, tank skin is that steel band is wound up as that superimposed position between spiral fashion, adjacent spiral forms the anticreep groove, inboard rotational moulding is made up of polyethylene layer, and the junction of steel band and steel plate is fixed together.

In order further to realize the purpose of this utility model, can be the enhancing muscle that projection is arranged in the outside of steel band.

In order further to realize the purpose of this utility model, can be polyethylene layer to be arranged at steel band outside plastic-blasting.

In order further to realize the purpose of this utility model, the steel plate outside plastic-blasting at the bottom of can being jar has polyethylene layer.

Compared with the prior art the utility model has following distinguishing feature and good effect: the utility model employing jar end is that the inboard rotational moulding of steel plate has polyethylene layer, tank skin is that steel band is wound up as spiral fashion, superimposed position between adjacent spiral forms the anticreep groove, the both sides of steel band are that polyethylene layer is formed, the junction of steel band and steel plate is fixed together, so just with less steel and poly consumption, solved the high consumptive material of existing storage tank, the problem that low-intensity and cost are high, polyethylene layer is embedded in the middle of the anticreep groove in the rotational moulding process, eliminate existing plastic inner lining fully and irritated the delamination of wall, again because steel band and steel plate strengthen wrapping in fully in the polyethylene layer of structure, the erosion that has completely cut off external environment and inwall fluid, has withstanding corrosion, the characteristics that life-span is long, thicker rotational moulding polyethylene layer is suitable for the container of requirement accumulating severe corrosive, the junction of steel plate and steel band is fixed together, the interliner of jar is an one, has improved the intensity of tank body greatly; Appearance at steel band is fixed with protruding enhancing muscle, guarantees that storage tank has enough strength and stiffness; The outside plastic-blasting of the steel plate at the jar end has polyethylene layer, has completely cut off the external environment erosion, has prolonged service life.
