An anti-unloader clogging device for cement production

Abstract

The invention discloses an unloader blockage preventing device for cement production. The device comprises an unloader main body; a discharge pipe is fixedly mounted on the right side of the unloadermain body; an inner gear is movably mounted at the upper end in the discharge pipe; a movable gear is engaged with teeth of the inner gear; a fixed gear is engaged with teeth of the movable gear; thecircle center of the fixed gear is movably mounted with the discharge pipe through a fixed rod; a movable rod is fixedly mounted on the outer surface of the inner gear; and the lower end of the movable rod is hinged with a hinge rod and a pressing plate. Through cooperative use of the movable rod, the hinge rod, the pressing plate, a clamping plate, a movable column, a clamping block and a stopper, an unloading port can be automatically dredged when cement is discharged from an unloader, so that the advantage of preventing blockage of the unloader is achieved, the unloader cannot be blocked, the manual dredging is not needed to guarantee the health of workers, the working efficiency is improved, and the use by people is convenient.

Description

technical field [0001] The invention relates to the technical field of cement production, in particular to an anti-blocking device for an unloader used in cement production. Background technique [0002] The cement production process can be referred to as "two grinding and one burning". The first is raw meal grinding: after the raw materials are crushed or dried, they are blended and ground in a certain proportion, and prepared into a raw meal with suitable ingredients and uniform quality, which is called the first stage; the second is clinker calcination: the raw The raw material is put into the cement kiln and calcined until it is partially melted to obtain cement clinker with calcium silicate as the main component; the third is cement grinding. The clinker is added with an appropriate amount of gypsum, and sometimes some mixed materials are added to grind together into cement. Links: mining → crushing → pre-homogenization → batching → raw meal grinding → raw meal homogen...

AI Technical Summary

Problems solved by technology

[0003] However, in the above-mentioned process of cement homogenization, when the homogenized cement is unloaded through the unloader, the unloader will often be blocked. Generally, when the unloader is blocked, it is done manually. Confirm whether the unloader is placed stably, and work from the side of the unloader to avoid damage caused by raw materials spraying out, and dredge the unloader. However, this method has a particularly low work efficiency and requires the staff to have Good awareness of danger prevention, if you don’t pay attention a little, the dredging staff will be injured by the sprayed raw material, which is inconvenient to use
