Plunger type continuous extrusion granulator and activated carbon granulation process

Abstract

The invention discloses a plunger type continuous extrusion granulator. The granulator comprises a plurality of sets of granulating unit and a set of driving unit. Each set of granulating unit comprises a pushing device, a material storage cylinder and a compression device, wherein the pushing device comprises a roller, a pressing rod and a pressing head, one end of the pressing rod is connected with the pressing head, and the other end of the pressing rod is provided with a roller; the material storage cylinder comprises cylinder walls and a die-casting die, the cylinder walls are arranged onthe two sides and the bottom of the material storage cylinder, the die-casting die is arranged at one end of the material storage cylinder, the pressing head is located in the material storage cylinder, and the cylinder walls, the die-casting die and the pressing head form a frame structure; and the compression device comprises a spring support, a spring and a connecting rod, the spring support is arranged on the cylinder walls, the connecting rod is arranged on the pressing rod, and the spring is connected with the spring support and the connecting rod. The driving unit comprises a cam and adriving shaft, wherein the cam is connected with the driving shaft, makes contact with the roller and drives the roller to rotate. The granulator disclosed by the invention is an activated carbon molding granulator which is simple in principle, high in yield, stable in operation and high in reliability.

Description

technical field [0001] The invention relates to a granulator, in particular to a plunger type continuous extrusion granulation equipment and a granulation process of activated carbon, belonging to the field of metallurgical sintering. Background technique [0002] In recent years, with the implementation of China's environmental protection policy, the activated carbon (large granular activated carbon, the same below) industry for flue gas purification has developed rapidly. The domestic demand for activated carbon continues to grow, and the supply of activated carbon is seriously in short supply. [0003] At present, the scale of activated carbon production enterprises is small, the production process is not perfect, there is no unified process standard and production equipment, and the output and quality are low and unstable. With the increasing popularity of activated carbon desulfurization and denitrification technology in the field of flue gas purification in the iron an...

Problems solved by technology

[0003] At present, the scale of activated carbon production enterprises is small, the production process is not perfect, there is no unified process standard and production equipment, the output and quality are low and unstable

With the increasing popularity of activated carbon desulfurization and denitrification technology in the field of flue gas purification in the iron and steel industry, the existing activated carbon production capacity and production technology can no longer meet the supply of activated carbon daily consumption, and have seriously restricted the continued development of activated carbon desulfurization and denitrification technology

[0004] The bottleneck of the existing activated carbon production technology is insufficient production capacity of the molding equipment, low equipment output, fast wear and poor operation stability
