Release agent heating and spraying device with good heat preservation effect

Abstract

The invention relates to the technical field of bridge sleeper manufacturing, in particular to a release agent heating and spraying device with a good heat preservation effect. The release agent heating and spraying device with the good heat preservation effect comprises an outer tank with moving wheels arranged at four corners of the outer wall of the bottom, wherein an inner tank is arranged in the outer tank; a lifting rotating mechanism is mounted between the bottom end of the inner tank and the outer tank; and a driving mechanism is mounted between the top end of the inner tank and the outer tank. According to the release agent heating and spraying device with the good heat preservation effect provided by the invention, the arranged driving mechanism is matched with the lifting rotating mechanism, an electric telescopic rod can be used for pushing a pressing ring plate to move downwards, then the inner tank is pushed to move downwards, and meanwhile, a spiral outer rib on a lifting cylinder moves along an inner spiral rib groove in a fixed bottom sleeve, so that the inner tank can rotate while the inner tank moves downwards; and on the contrary, the electric telescopic rod is drawn back to be matched with a reset spring, so that the inner tank can reversely rotate in the upward moving process, forward and reverse rotation of the inner tank in a short time is achieved, and the heating uniformity of a release agent is improved.

Description

technical field [0001] The invention relates to the technical field of bridge sleeper manufacture, in particular to a heating spraying device for a release agent with good thermal insulation effect. Background technique [0002] Bridge sleepers are mainly used on bridges to support and maintain the position of the rails. At the same time, bridge sleepers need to transfer the huge pressure from the rails to the ballast bed. It has a certain degree of flexibility and elasticity. In the production process of bridge sleepers, in order to facilitate the demoulding of subsequent finished products, it is necessary to spray a release agent on the sleeper mold. In a low-temperature working environment, the release agent will be more viscous and fluidity will become poor, which will affect the normal spraying atomization and spraying quality. [0003] After retrieval, the Chinese invention patent document with the publication number CN111414026A discloses a radiation type sleeper mo...

Problems solved by technology

[0005] (1) When the above patents are used, the heating uniformity of the internal release agent is still not ideal, and the release agent near the outside will be heated first, so the center The release agent at the position is heated slowly, and its uniform heating is more dependent on the flow of the release agent itself, which also affects the control of the temperature of the release agent;

[0006](2) The above-mentioned patent is equipped with an air booster mechanism, but it does not take advantage of the entry of air, resulting in a single means of achieving uniform heating in the above-mentioned patent, and the actual heating effect cannot To achieve the expected uniform effect, so there are certain limitations
