Description

Technical Field

[0001] This utility model relates to a discharge device for a rotary drum dryer for metallurgical materials, belonging to the technical field of rotary drum dryers. Background Technology

[0002] Rotary drum dryers are a type of traditional drying equipment. They are reliable, flexible, adaptable, and have a large processing capacity, making them widely used in metallurgy, building materials, chemicals, coal washing, fertilizers, ores, sand, clay, kaolin, sugar, and other fields. The machine mainly consists of a rotating body, lifting plates, a transmission device, a support device, and sealing rings. The dryer is a cylinder slightly inclined horizontally. Material is fed from the higher end, and high-temperature hot flue gas flows into the cylinder concurrently with the material. As the cylinder rotates, the material moves to the lower end due to gravity. Lifting plates on the inner wall of the cylinder lift and scatter the material, increasing the contact surface between the material and the airflow to improve the drying rate and promote material movement. The dried product is collected from the bottom.

A servo motor 202 is fixedly connected to the right side of the discharge cylinder 201. A rotating shaft 203 is fixedly connected to the output end of the servo motor 202. A spiral blade 204 is fixedly connected to the outer surface of the rotating shaft 203.

[0023] By setting up the discharge mechanism 200, the material is pushed by the continuous rotation of the spiral blade 204. The discharge amount can be precisely controlled by adjusting the speed of the servo motor 202 output end, which can stably output a quantitative amount of material and avoid the problems of inconsistent speed or agglomeration and spillage in traditional gravity discharge.

[0024] Example 2 like Figure 4As shown, in one embodiment, a discharge device 300 is also included. The discharge device 300 includes a discharge hopper 301, which is fixedly connected to the right side of the bottom of the discharge cylinder 201 and located below the discharge port. Gears 302 are movably connected to the left and right sides of the front and rear sides of the discharge hopper 301 via rotating shafts. Two sets of gears 302 form a group, and each group of gears 302 meshes with each other. A swing plate 303 is fixedly connected to the front side of each gear 302, and each group of swing plates 303 is arranged opposite to each other. The inner side of each group of swing plates 303 is connected via… The door panels are connected, and the front sides of the two swing plates 303 on the front side are fixedly connected to the connecting plates 304. A cylinder 305 is provided between the connecting plates 304, and the left side of the cylinder 305 is fixedly connected to the right side of the connecting plate 304 on the left side. The telescopic end of the cylinder 305 is fixedly connected to the left side of the connecting plate 304 on the right side. A fixing plate 306 is fixedly connected to the outer side of the swing plates 303. The fixing plate 306 on the front side and the fixing plate 306 on the back side are a group of each other. A fixing rod 307 is fixedly connected between each group of fixing plates 306.

[0025] By setting up the discharge device 300, the discharge volume can be precisely controlled, avoiding material accumulation or uneven discharge, which greatly improves production efficiency.

[0026] Example 3 like Figure 5 and Figure 6 As shown, in one embodiment, a support assembly 400 is provided at the bottom of the outer surface of the discharge cylinder 201. The support assembly 400 includes a base plate 401. Support legs 402 are fixedly connected to the front and rear sides of the top of the base plate 401. An arc-shaped plate 403 is fixedly connected to the top of the support legs 402.

[0028] In operation, the following steps are taken: First, after the metallurgical material enters the drum dryer body 101 for drying, the inside of the drum dryer body 101 is cleaned by the cleaning device 102. Then, the material enters the inner cavity of the discharge cylinder 201. The output end of the servo motor 202 drives the rotating shaft 203 and the spiral blades 204 to rotate, so that the material enters the discharge port at a uniform speed and falls into the inner cavity of the discharge hopper 301. The cylinder 305 can be extended and retracted to drive the swing plate 303 to swing, thereby controlling the distance between the two swing plates 303 and controlling the material discharge speed. When the gap between the swing plates 303 is large, the material discharge is fast; when the gap between the swing plates 303 is small, the material discharge is slow. The material is discharged after being filtered by the filter screen 308.

[0029] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model.
