Description

Corrosion-resistant durable stainless steel water tank Technical Field The utility model relates to the technical field of stainless steel water tanks, in particular to a corrosion-resistant durable stainless steel water tank. Background Compared with other water tanks, the stainless steel water tank has the advantages of attractive appearance, light weight, high strength, corrosion resistance, high temperature resistance, clean water quality, seepage prevention, shock resistance, no moss generation, no secondary pollution to water quality, convenient installation, no maintenance, convenient cleaning and the like, and the welding seam on the traditional stainless steel water tank has high-temperature aging risk in the long-term use process, and the water tank is damaged outside, so that the inside is separated from the protective layer to be contacted with the outside, the corrosion phenomenon of the easily oxidized part in the inside can be accelerated, and the service life of the product is reduced. The novel corrosion-resistant square stainless steel water tank with welding seams is disclosed by the retrieved Chinese patent (publication No. CN 212244696U), the number of the tanks to be installed can be adjusted according to actual needs, so that the overall total capacity of the water tank is adjusted, a corrosion-resistant coating is arranged in the tank body to improve the corrosion resistance, a waterproof layer is added at the welding seams to improve the tightness, the outside of the tank body is manually drawn to improve the wear resistance, detachable filter screens are arranged on a water inlet and a water outlet, the impurity amount entering the water tank is reduced, the stability of the water storage quality is kept, and the filter screens are convenient to clean. However, the practical application finds that the technical scheme still has at least the following defects: According to the scheme, after the adjacent box bodies are welded and connected, only the seam on the outer side of the box body is welded and coated with the waterproof layer, so that a tiny seam still exists in the inner side joint of the box body, the water body is easy to infiltrate into the seam to form a long-term humid and anoxic closed environment in the use process, seam corrosion is extremely easy to induce, and even if the inner side seam is welded, a welding seam heat affected zone is still likely to form a corrosion weak point due to problems of metallographic structure change, surface oxide skin residue and the like, and further local damages such as pitting corrosion, stress corrosion and the like are caused, so that the tightness and the structural reliability of the water tank are affected. Disclosure of utility model The utility model aims to provide an anti-corrosion durable stainless steel water tank to solve the problems in the prior art, the first butt joint groove and the second butt joint groove are arranged to form a three-dimensional staggered joint structure, the baffle plate integrally formed at the bottom of the inner wall of the second tank body and the rubber pad covered at one end of the baffle plate are matched, the welding-free sealing treatment of the inner joint of the water tank is realized, the sealing performance is improved, the problems of seam corrosion and pitting corrosion caused by humid and anoxic environments at the inner joint are effectively avoided, the rubber pad has elasticity and a certain height, the sealing path is prolonged and the waterproof effect is enhanced by prepressing the inner wall of the first butt joint groove between the inner wall of the water tank and the baffle plate in the assembly process, the liquid residue is avoided by the smooth transition structure of the baffle plate and the inner wall of the tank body, the sealing structure is convenient to clean and maintain, compared with the traditional water tank structure which is sealed only by welding, the sealing structure is improved, the sealing structure is remarkably simplified, the sealing stress effect is reduced, the sealing performance is improved, the sealing performance is better, the service life is prolonged, and the structure is better in terms of being innovative.
