Description
Technical Field
The invention relates to a vertical spiral honeycomb ceramic vacuum continuous extruder.
Background
With the development of human society, people have stronger consciousness on environmental protection, not only guarding the earth's environment, but also wanting to create an ecological environment which can make people more vigorous. The honeycomb ceramic carrier is widely applied to the fields of various automobile tail gas treatments, purification of industrial kiln exhaust gas, filtration of various edible liquids and the like, and has higher and higher requirements on the quality and performance of the honeycomb ceramic carrier, in particular to a large-caliber honeycomb ceramic diesel vehicle carrier. At present, various types of honeycomb ceramic extruders can not completely meet the production process requirements of large-caliber honeycomb ceramic diesel vehicle carriers.
The honeycomb ceramic extrusion molding machine at home and abroad mainly comprises: horizontal mechanical screw extrusion and vertical hydraulic piston extrusion.
Horizontal mechanical screw extrusion type characteristics: high efficiency, good consistency of products and stability. The defect that the density of the middle point of the extruded product is poor, and the product is easy to open is formed, because the symmetrical spiral blades are extruded in a rotating way, mud is not discharged from the middle, a small point is arranged in the middle to form a mud discharging blind area, and the mud is extruded and filled by mud materials. The extruded pug is easy to generate heat, the vacuum chamber is easy to block, and only products with smaller caliber can be formed, because of the difficulty in transverse extrusion, transverse blank receiving and conveying, blank deformation is easy to cause, and large-diameter honeycomb ceramic products with the diameter exceeding 150mm are difficult to form.
Vertical hydraulic piston extrusion type characteristics: the extrusion pressure is large, the extrusion pressure and the speed are adjustable, the adaptability to mud materials is strong, products with various calibers can be produced, and the cleaning in the machine is easy and flexible. The defect is that intermittent extrusion, when intermittent mud adding section, air is inevitably brought into a charging barrel, if a vacuumizing device is not designed, when the brought air and mud are extruded at the same time under high pressure, the rapid expansion of air bubbles can destroy the extruded honeycomb ceramic product, the extrusion quality is seriously affected, and meanwhile, because the intermittent extrusion has lower working efficiency, the stability and consistency of the product are not as good as those of continuous extrusion.
