Description

Composite tank car hydrops box Technical Field The utility model relates to a composite material tank truck hydrops box, and belongs to the technical field of tank truck parts. Background Tank trucks in the existing market are mostly carbon steel, stainless steel and aluminum alloy, the construction scheme is that the tank trucks are welded or fixed on an integral vehicle frame or a semitrailer through metal binding bands, a platform at the top of each tank truck is basically of a metal structure, and the existing tank truck structure and materials with light weight and excellent performance are required in the market and are used for replacing the original metal structure, so that the competitive advantage of enterprises in the field of transportation tank trucks is improved. Compared with the metal, the novel composite material tank body reduces the weight by 40 percent or more, and can reduce the transport cost per pass. The tank body of the composite tank truck has the advantages of acid resistance and alkali resistance, can transport various media, is suitable for water, food media, oil media, acid media, alkaline media and other chemical media, and has stronger applicability and economy. And simultaneously, the service life of 15-20 years is satisfied, and less maintenance is required. The hydrops box on the existing metal tank body adopts metal welding, has more welding seams, heavier weight and short service life. And the metal structure is easy to corrode, especially when the tank body stores and transports strong acid and strong alkali, the hydrops box is easy to corrode as a hydrops device. How to prepare a composite tank car effusion box by adopting a composite material becomes the problem to be solved. Disclosure of utility model In order to solve the technical problems, the utility model provides a composite tank truck effusion box. In order to solve the technical problems, the aim of the utility model is realized as follows: The utility model relates to a composite material tank truck effusion box, which comprises a composite material box shell with an arc bottom, wherein a liquid discharge hole is arranged on the side wall of the composite material box shell near the bottom; The dropsy box further comprises a first composite fixing piece and a second composite fixing piece which are used for connecting the composite box shell and the tank body. On the basis of the scheme and as a preferable scheme of the scheme, the composite material box shell is provided with a liquid discharge groove at a position close to the liquid discharge hole. On the basis of the scheme, the liquid discharge hole is communicated with a liquid discharge pipe through a pultrusion pipe. On the basis of the scheme and as a preferable scheme of the scheme, composite materials are used for the composite box shell, the first composite material fixing piece, the second composite material fixing piece and the pultruded pipe. On the basis of the scheme, the composite material is a carbon fiber composite material, a glass fiber composite material or a carbon fiber/glass fiber mixed composite material. The composite material tank car hydrops box has the beneficial effects that the composite material replaces the traditional metal material, so that the weight can be reduced by 40%, products can be transported more, and better economic benefits are achieved. The welding is reduced, the modularization is fast and mass production is realized, and the tank body can be fast glued and solidified. The excellent corrosion resistance of the material is utilized, the service life is long, and the problems of corrosion resistance and oxidation of the material in long-time use are solved.
