Material guiding device of vertical pre-heater

Abstract

The invention discloses a material guiding device of a vertical pre-heater. The material guiding device comprises a hydraulic push rod, a framework, a connecting rod, a material guide rod, a guide rail, a limiting component, a sealing structure and a pre-heater body, wherein one end of the hydraulic push rod is connected to the pre-heater body, a piston rod of the hydraulic push rod is connected with the lower end of the framework, and the upper end of the framework is movably connected to the pre-heater body; the limiting component is arranged at a position on the pre-heater body corresponding to the upper end of the framework; the framework is connected with one end of the connecting rod, and the other end of the connecting rod is connected with the material guide rod; the material guide rod is arranged on the guide rail on the pre-heater body; and the sealing structure is arranged at the connecting end of the material guide rod and the connecting rod. The material guiding device is connected to the pre-heater body to reduce the occupied space, can realize smooth material guiding operation, has a simple structure, is convenient to install, adjust and replace, and cannot be blocked easily.

Description

technical field [0001] The invention relates to a material introduction device, in particular to a material introduction device for a lime calcining vertical preheater. Background technique [0002] The vertical preheater is the main process equipment of the active lime rotary kiln calcination system. It uses the high-temperature flue gas discharged from the tail of the rotary kiln to exchange heat with the normal-temperature material, so that the material is preheated to above 900°C before entering the rotary kiln, and achieves a pre-decomposition of more than 25%, which improves the rotary kiln. The production capacity of the kiln is improved, and the exhaust gas temperature is reduced, energy consumption is saved, and it provides convenience for the exhaust gas treatment at the rear. The push rod device is the main part of the preheater, which is used to evenly introduce the material into the rotary kiln. [0003] At present, the commonly used preheater material introdu...

AI Technical Summary

Problems solved by technology

The maximum stroke and thrust of the push rod of the floor-standing structure are relatively large, but the structure is complex, the equipment is relatively heavy, and the heat-resistant steel is consumed. There are certain deficiencies in the sealing structure, the return material brought in by the push rod cannot be discharged well, and it is easy to block
