Description

Clinker unloader for cement manufacture

Technical Field

The invention relates to the technical field of cement production, in particular to a clinker blanking device for cement production.

Background

With the rapid development of the building industry, the use demand of cement is higher and higher, the rotary cement kiln is an indispensable device in the cement production process, and is used for calcining cement raw materials to prepare cement clinker, the cement clinker is in a large-particle or block structure and needs to be conveyed to a grinding process by a clinker conveyor to be ground to a proper particle size, so that the hydration area of a cement product is increased, the hydration speed of the cement is accelerated, and the cement meets the speed requirements of cement slurry condensation and hardening when in use.

The patent number CN210752968U discloses a clinker discharging device for cement production and processing, in which a discharging part outputs crushed cement clinker to a belt in a casing, and the belt drives the cement clinker to move under the action of the driving force of a driving roller. In the above-mentioned in-process, cement clinker falls to the in-process of belt, the inevitable raise dust phenomenon that produces cement clinker, the belt has been covered to the casing, raise dust has been avoided, but the casing inner space is airtight and narrow and small relatively, the cement clinker of unloading portion output nevertheless lasts and arrives in the casing, so the exhaust tube in time takes out the air in the casing, guarantee the smooth and easy unloading of cement clinker, and filter piece has avoided the grog dust to flow out the casing through the exhaust tube, damage air exhaust equipment, but filter piece continuous filtering dust, after the dust adheres to certain thickness on filtering piece, filter piece will lose the function that makes the air pass through, so the drive roller drives the cam simultaneously, the cam rotates, high-hour is low when the upper limb of cam, drive butt joint board reciprocating motion from top to bottom. When the top connection plate moves downwards, one end of the transmission rod moves downwards, the other end of the transmission rod drives one end of the vibrating rod to move downwards, the other end of the vibrating rod rotates upwards, the other end of the vibrating rod abuts against the filtering piece and impacts the filtering piece, and therefore the filtering piece is prevented from being attached with thick dust; when the top connection plate moves upwards, the other end of the rapping rod is far away from the filter piece, and preparation is made for next filter piece impacting. When the drive roller drives the belt, also make to filter and receive periodic rapping, guaranteed the continuous discharge of air in the casing, also avoided the raise dust, this technical scheme still has the defect:

firstly, in the technical scheme, the material conveying roller can only feed the next time when rotating for one circle, the blanking speed is very low, and the blanking is easy to cause accumulation and blockage when passing through an efficiency hole;

second, this technical scheme rotate through a plurality of broken wheels, smash the material, smash the effect relatively poor, are difficult to carry out even crushing to the material.
