Storage appliance used in thiourea production process

Abstract

The invention relates to the technical field of thiourea production, in particular to a storage appliance used in the thiourea production process. An outer cylinder is included, and a pedestal is arranged on a bottom plate of the outer cylinder; an inner cylinder is arranged above the pedestal; a waterproof layer is arranged on the inner wall of the inner cylinder; and a flame-retardant layer is arranged on the outer wall of the outer cylinder, a cooling fin plate is inserted into the outer wall of the outer cylinder in a connected manner, a damping pad is arranged on the bottom surface of theouter cylinder, a mounting plate is arranged on the outer wall of the outer cylinder, a hydraulic cylinder is arranged on the surface of the mounting plate, a piston rod of the hydraulic cylinder penetrates through the mounting plate and then is fixed to the top surface of a lifting ring, and universal wheels are arranged on the bottom face of the lifting ring. The storage appliance has the beneficial effects that the storage appliance used in the thiourea production process adopts a double-layer cylinder structure, a cavity between double layers of cylinders is filled with clear water to play a blocking role, and the cooling fin plate is inserted into the surface of the outer cylinder to dissipate heat and cool the clear water, so that thiourea collected in the inner cylinder is prevented from being decomposed due to high storage environment temperature.

Description

technical field [0001] The invention relates to the technical field of thiourea production, in particular to a storage device used in the production process of thiourea. Background technique [0002] Thiourea is a white and shiny crystal. Bitter. Density 1.41. The melting point is 176-178°C. Decomposes at higher temperatures. Soluble in water, soluble in ethanol when heated, very slightly soluble in ether. Partially plays the role of isomerization during melting to form ammonium thiocyanate. It is used as a raw material for the manufacture of medicines, dyes, resins, compression molding powder, etc. It is also used as a vulcanization accelerator for rubber and a flotation agent for metal minerals. It is formed by the action of hydrogen sulfide and lime slurry to form calcium hydrosulfide, and then react with cyanamide (based) calcium chloride. It can also be prepared by melting ammonium thiocyanide, or by reacting cyanamide with hydrogen sulfide. [0003] In the prio...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, the structure of the thiourea storage cylinder is simple, and the rise of the surface temperature of the storage cylinder will cause the decomposition of thiourea, releasing toxic gases such as nitrogen and sulfur oxides; and the movement of the storage cylinder is very laborious; therefore, the present invention A storage device used in the production process of thiourea is proposed to solve the above problems
