Description

Technical Field

[0001] The utility model relates to the technical field of shaft kiln feeding equipment, in particular to a uniform feeding mechanism for a vertical calcination kiln. Background Technique

[0002] Vertical calcination kilns (hereinafter uniformly referred to as shaft kilns) are commonly found in lime kilns. When carrying out the calcination work, the top-in and bottom-out feeding and discharging method is adopted. The top feeding commonly uses the combination of a hoist and a feeding chute. The hoist lifts the materials on the ground to the top of the kiln, and then obliquely sends them into the kiln through the feeding chute. However, this feeding method is prone to material accumulation, resulting in too high material height, which is not conducive to the entry of materials into the shaft kiln and the calcination effect.

[0003] In the prior art, the application number is CN202322600452.0, and the name is a feeding structure of a lime roasting shaft kiln. It drives the rotation of the feeding hopper by a power unit. The long strip-shaped discharge port cooperates with the rotation of the feeding hopper, so that it can feed along the circumferential direction of the shaft kiln, making the feeding more uniform. In addition, a stirring mechanism is also provided in the feeding hopper to prevent the raw materials from being blocked in the shaft kiln and improve the production efficiency. However, this feeding structure has inconveniences in use. One is that it is difficult to control the feeding amount. Only by controlling the feeding amount into the feeding hopper can the feeding amount be controlled, and the material amount is unstable. The other is that the motor needs to drive the feeding hopper and the materials therein to rotate together. The motor power output is large, the power consumption is high and it is easy to be damaged. Content of the Utility Model

[0004] The purpose of the utility model is to provide one to solve the problems that the feeding structure has inconveniences in use, it is difficult to control the feeding amount, the motor power output is large, the power consumption is high and it is easy to be damaged.

[0005] To solve the above technical problems, the utility model adopts the following technical solutions:

[0006] A uniform feeding mechanism for a vertical calcination kiln, including a shaft kiln. A uniform feeding mechanism is arranged at the top of the shaft kiln.

One end of a right-angle commutator on the distributing pipe is connected to the outer end of the rotating shaft, and the other end of the right-angle commutator is connected to a first auger in the distributing pipe. The second motor is connected to the feeding pipe through a gear structure.

[0007] A further technical solution is that a second auger located inside the blanking pipe is installed on the rotating shaft.

[0008] A further technical solution is that a vibration motor is installed on the outer side wall of the hopper.

[0009] A further technical solution is that the discharging end of the blanking pipe and the feeding end of the cloth pipe are communicated through a transition pipe, and the transition pipe is inclined.

[0010] A further technical solution is that the length of the cloth pipe is the same as the radius of the inner cavity of the vertical kiln.
