Description

Technical Field

[0001] The utility model relates to the technical field of cement production, in particular to a conveying device for accurately adding dechlorination ash. Background Art

[0002] A steel silo is set up on the cement mill mixed material conveyor belt, and the powder ash of the dechlorination system is pneumatically transported to the silo for storage through a pipeline. Ash metering equipment is installed at the bottom of the silo. During the production of low-grade cement, dechlorination ash is quantitatively added to the cement mill mixed material conveyor belt according to the chloride ion content to achieve stable disposal of dechlorination ash, thereby reducing the chloride ion content in the clinker and increasing the addition space of the solid and hazardous waste system.

[0003] Although the existing technology has many benefits during use, it still has the following problems: the transportation accuracy of the dechlorination ash is poor. When the existing dechlorination ash is transported to the upper end of the conveyor belt, the impact force between the dechlorination ash and the material will cause the material to be lifted, causing pollution to the working environment, and affecting the mixing accuracy between the dechlorination ash and the material. Utility Model Content

[0006] When using a conveying device for accurately adding dechlorination ash in the present technical solution, the staff manually moves the screw to adjust the position of the extension pipe outside the discharge pipe, and adjusts the height of the discharge pipe at the upper end of the conveyor belt so that the discharge pipe is buried in the material at the upper end of the conveyor belt. The position of the extension pipe is then fixed by a nut, and the dechlorination ash inside the silo is discharged through the feed pipe, reamer body, discharge pipe, extension pipe and discharge pipe until the dechlorination ash can be discharged into the accumulated material.

The reamer body conveys the dechlorinated ash until it is discharged through the discharge pipe, and the reamer body is capable of controlling the delivery amount of the dechlorinated ash.

[0008] Preferably, a conveyor belt is provided on the outer wall of the transmission roller, and the conveyor belt is located at the lower end of the extension tube. The conveyor belt and the transmission roller transport the fly ash.

[0009] Preferably, a discharge pipe is plugged and installed at the lower end of the outer wall of one side of the extension pipe, and the discharge pipe is connected with the inside of the discharge pipe through the extension pipe. The material inside the discharge pipe is discharged through the extension pipe and the discharge pipe.

[0010] Preferably, a sealing ring is fixed on one side of the outer wall of the discharge pipe, and the sealing ring contacts the inner wall of the extension pipe. The sealing ring ensures the sealing between the discharge pipe and the extension pipe.

[0012] Preferably, the outer walls on both sides of the screw are threadedly connected with nuts, and the nuts are distributed on the upper and lower sides of the fixing block. The nuts fix the screw to ensure the position stability of the screw outside the fixing block.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: the present invention achieves the effect of dust reduction by arranging an extension pipe, a discharge pipe and a screw rod; the staff manually moves the screw rod to adjust the position of the extension pipe outside the discharge pipe, and adjusts the height of the discharge pipe at the upper end of the conveyor belt so that the discharge pipe is buried in the material at the upper end of the conveyor belt; the position of the extension pipe is then fixed by a nut, and the dechlorination ash inside the silo is discharged through the feed pipe, the reamer body, the discharge pipe, the extension pipe and the discharge pipe until the dechlorination ash can be discharged into the accumulated material, avoiding the occurrence of dust, thereby avoiding the phenomenon of waste of dechlorination ash, and ensuring the accuracy of the amount of dechlorination ash mixed into the material.
