Continuous high pressure steeping device and method

Abstract

The invention discloses a continuous high pressure steeping device and a method, particularly to a continuous high pressure steeping device and a method suitable for industries of carbon, metallurgy and the like. A conveyer No. 4, a preheating chamber, a steeping tank, a cooling chamber, a conveyer No. 7 and a hooking and pulling machine are positioned on the same straight line and sequentially arranged in the continuous high pressure steeping device; trolleys No. 1, No. 2 and No. 3 are installed on a railway, and the trolleys No. 1, No. 2 and No. 3 and conveys, No. 1 No. 2, No. 3 and No. 4 are all provided with a pusher. The continuous high pressure steeping device and the method have the advantages and the effects that energy sources are effectively utilized, and the steeping efficiency is improved; the whole high pressure steeping process is continuously carried out, automated control is easy to realize, and the labor intensity of worker is lowered.

Description

technical field [0001] The invention relates to a continuous high-pressure impregnation device and method, in particular to a continuous high-pressure impregnation device and method suitable for industries such as carbon and metallurgy. Background technique [0002] In the production process of graphitized cathode and electrode, in order to increase the density of the product, reduce the porosity and permeability, increase the mechanical strength of the product and improve the electrical and thermal conductivity, high-pressure impregnation technology is often used to allow high-temperature liquid asphalt to penetrate into the product. in the pores. Existing impregnation production such as figure 2 As shown, the intermittent high-pressure impregnation technology is mainly used. First, the product to be impregnated is loaded into the steel basket, and the steel basket is placed on the transfer vehicle 24 by a crane, and the transfer vehicle 24 is moved to one of the three pre...

AI Technical Summary

Problems solved by technology

The preheated product is taken out by the transfer car 24 until it is pushed into the dipping tank. It takes a long time, the heat dissipation of the product to the air is relatively large, and the temperature of the product cannot be controlled, which affects the dipping effect; The impregnation tank is cooled by water spray, and the temperature of the impregnation tank is significantly reduced. When the next cycle of impregnation operation is performed, the impregnation tank needs to be heated, which not only wastes heat energy, but also has a longer heating cycle, which affects the impregnation efficiency; The liquid asphalt in the impregnation tank cannot be completely removed, resulting in high tar content in the cooling water and serious water pollution; when the door of the impregnation tank is opened, there is a large amount of smoke, and it is difficult to collect dust, and the workshop environment is poor
