Preferably, a welding reinforcing hole is drilled at the cross-shaped joint of the plane connection of the water tank plates, and the welding reinforcing hole is penetrated by a lacing wire for welding reinforcement.

Preferably, the lacing wire penetrates through the water tank plate and is left in the water tank outside the part of wrapping one deck plastics, conveniently welds with the nexine plastic slab, and the part that stretches out the water tank plate outside is the harness cord, conveniently with the stainless steel fixed connection of outside.

Preferably, the thickness of the stainless steel plate on the outer layer of the water tank plate is 0.3-2mm, and the thickness of the plastic plate on the inner layer is 8-9.7 mm.

The utility model adopts the welding between the water tank plates inside the water tank due to the use of the composite material of stainless steel and plastic, the water tank plates outside the water tank are connected by bolts, and the cross center formed after the connection of the water tank plates is drilled and reinforced by the lacing wire perforation, thereby saving the link of argon arc welding, avoiding the pollution and the harm caused by material denaturation, and greatly prolonging the service life of the water tank; rubber leather strips and glass cement are not used as a plugging mode, so that the industrial cost is reduced, the rust never occurs, the water quality is not polluted, and the method is environment-friendly and sanitary; because of using the composite material, the thickness of the inner layer plastic greatly exceeds the thickness of the outer layer stainless steel, the cost is greatly reduced, and the integral strength is increased; the internal tie bars are combined simply and conveniently by adopting a harness cord integral plastic-attached technology, the external tie bars can be combined at will by being fastened by screws, the internal plastic is welded, no pollution is caused, no deformation is caused, the technology is environment-friendly, and the service life is prolonged; the modular production, the transportation of being convenient for, the simple installation, rational in infrastructure.

Detailed Description

Referring to fig. 1-5, in the embodiment of the present invention, the outer layer of the water tank plate is a stainless steel plate of 0.3-2mm, 304/201/galvanized steel plate is used, the inner layer is a plastic plate of 8-9.7mm, polypropylene PP/polyethylene PE/PVc material is used, and the inner layer and the outer layer are compounded into a whole, which is light and low in cost. The water tank plate body 1 is in a spherical shape with an outer drum and an inner recess, and four sides of the water tank plate are two continuous 45-degree outward-bending flanges. According to the size requirement, if the water tank is large, a plurality of water tank plates need to be connected with each other by using the outer flanging 3 to form the same plane of the water tank with the required size, and the water tank plates are connected with each other by using the inner flanging 2 to form two vertical surfaces of the water tank. The inside of the water tank is plastic, so plastic welding rods 7 are adopted for welding, and the outside of the water tank is a stainless steel plate which is reinforced and connected through screws. The connecting mode overcomes the defect that the prior water tank uses rubber strips and glass cement as a plugging mode, has no pollution, no deformation, environmental protection and prolonged service life. The cross joint department that four water tank boards on coplanar formed after connecting jointly bores has welding reinforcement hole 6, and the lacing wire is worn the outside from the inside, stays the part outside parcel one deck plastics of water tank the inside, and the part that stretches out the water tank board outside is the harness cord, passes through lacing wire baffle 4 fastening connection with outer corrosion resistant plate conveniently with the welding of nexine plastic slab. Other water tanks such as an exhaust port, a water inlet, a water outlet, an overflow port, a bottom drain outlet, a liquid level pipe, a ladder stand, a manhole and the like are normally arranged at corresponding positions according to specific requirements at will, and 5 is a connecting hole formed in the outward-turned edge of the water tank plate and used for penetrating a screw to be fixedly connected with the water tank plate.

The manufacturing method comprises the steps of firstly, manufacturing a stainless steel plate into a plate with an outer drum and an inner recess through a cold pressing technology, wherein four edges of the plate are two continuous outward turned edges of 45 degrees, and connecting holes are punched on the outward turned edges; then putting the stainless steel plate into a mould, injecting a plastic matrix into the mould by using an injection molding machine to ensure that the surface of the stainless steel is uniformly wrapped by the plastic, cooling and demoulding together with the stainless steel plate to form a composite water tank plate with the inner layer made of the plastic and the outer layer made of the stainless steel; finally, assembling, namely realizing the same plane connection of the water tank plates by using the 45-degree outer flanging at the outermost edge, realizing the vertical plane connection of the water tank by using the 45-degree inner flanging, welding the water tank plates in the water tank by using plastic welding rods 7, and reinforcing and connecting the water tank plates outside the water tank by using screws; holes are drilled at the cross-shaped joint formed by connecting the water tank plates on the same plane, and the water tank plates are reinforced by lacing wires through the holes.
