Description

Technical Field

[0001] The utility model belongs to the technical field of slag powder transportation, and specifically relates to an air chute transportation device for slag powder storage. Background Art

[0002] The air conveying chute is a pneumatic conveying device used to convey easy-flowing powdered materials. When conveying slag powder, the conveyed material is fed from the feed hopper at the high end of the upper trough, and the air is blown into the lower trough by a dedicated blower, and distributed between the material particles through the densely porous air permeable layer, so that the material undergoes so-called gasification to change the friction angle of the material, so that it forms a flowing state and slides down the slope to achieve the purpose of conveying.

[0003] A search of CN208747144U discloses an air chute conveying structure for storing granulated blast furnace slag powder. The gas entering the air inlet pipe is diverted through an air outlet channel and output to the bottom end surface of the air permeable layer. The gas output from the air permeable layer through the air outlet channel vibrates, thereby reducing the probability of the air permeable layer being blocked by the slag powder and improving the efficiency of the gasification treatment of the slag powder.

[0004] In this conveying structure, the slag powder is directly put into the hopper. However, the slag powder will clump during transportation. Some of the clumped slag powder directly put into the hopper will cause blockage inside the conveying chute, which will increase the subsequent maintenance cost and be inconvenient for the staff to use.

[0005] In view of this, the present utility model is proposed. Utility Model Content

[0010] As a preferred embodiment of the utility model, the collection mechanism includes a discharge chute opened on the outer wall of the crushing box, a slide groove is opened on the top of the inner wall of the discharge chute, a baffle is slidably connected to the inner wall of the slide groove, a paddle is fixedly connected to the outer wall of the baffle, and a magnet is fixedly connected to the top of the inner wall of the slide groove.

[0011] As a preferred embodiment of the present invention, an arc is provided at one end of the rotating rod away from the rotating shaft, and the length of the rotating rod exceeds the distance between the top end of the connecting rod and the rotating shaft.

[0012] As a preferred embodiment of the present invention, the outer wall of the rubber plate is larger than the inner wall of the through groove formed on the outer wall of the crushing box.

DETAILED DESCRIPTION

[0026] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model.

The inner wall is located on one side of the first crushing roller 316 and is fixedly connected to the second crushing roller 317. A rotating hole is provided on the inner wall of the crushing box 312, and a torsion spring 318 is fixedly connected to the inner wall of the rotating hole. A rotating rod 319 is fixedly connected to the end of the torsion spring 318 away from the inner wall of the rotating hole. A screening plate 3110 is fixedly connected to the outer wall of the rotating rod 319. A connecting rod 3111 is fixedly connected to the top of the screening plate 3110. A through groove is provided on the outer wall of the crushing box 312, and the outer wall of the connecting rod 3111 is movably connected to the inner wall of the through groove. A rubber plate 3112 is fixedly connected to the bottom of the end of the connecting rod 3111 away from the screening plate 3110, and the end of the rubber plate 3112 away from the connecting rod 3111 is fixedly connected to the bottom end of the inner wall of the through groove. A rotating rod 3113 is provided on the top of the connecting rod 3111, and one end of the rotating rod 3113 is fixedly connected to the outer wall of the rotating shaft 315.

[0028] Furthermore, an arc setting is provided at one end of the rotating rod 3113 away from the rotating shaft 315, and the length of the rotating rod 3113 exceeds the distance between the top of the connecting rod 3111 and the rotating shaft 315. In this way, when the rotating rod 3113 rotates to one side of the connecting rod 3111, the connecting rod 3111 can be squeezed downward, thereby driving the screening plate 3110 to move downward.

[0029] Furthermore, the outer wall of the rubber sheet 3112 is larger than the inner wall of the through slot formed in the outer wall of the crushing box 312 , so that the rubber sheet 3112 will fill the inner wall of the through slot due to the rebound effect, thereby preventing the slag powder inside the crushing box 312 from spilling out.

[0030] Furthermore, the initial state of the screening plate 3110 is an inclined state with the left side lower and the right side higher, and an arc setting is provided at the end of the screening plate 3110 away from the rotating rod 319, so that the agglomerated slag powder can be easily rolled to the left side by the shaking of the screening plate 3110, so as to collect and gather the slag powder.

[0031] The collecting mechanism 32 includes a discharge chute 321 provided on the outer wall of the crushing box 312 , a slide chute 322 is provided on the top of the inner wall of the discharge chute 321 , a baffle 323 is slidably connected to the inner wall of the slide chute 322 , a paddle 324 is fixedly connected to the outer wall of the baffle 323 , and a magnet 325 is fixedly connected to the top of the inner wall of the slide chute 322 .

[0032] Furthermore, the outer wall of the baffle 323 fits snugly with the inner wall of the discharge trough 321 , so that the inner wall of the discharge trough 321 can be completely blocked to prevent the slag powder inside from spilling out, so that the agglomerated slag powder can be collected on one side of the crushing box 312 .

[0033] Furthermore, the outer wall of the baffle 323 fits snugly with the inner wall of the chute 322, so that the stability of the baffle 323 during the up and down movement can be ensured, thereby ensuring that the baffle 323 will not shake and produce gaps to cause leakage of slag powder.

[0034] The implementation principle of the slag powder storage air chute conveying device of the present embodiment is as follows: first, the motor 314 is started, and its output end will drive the rotating shaft 315 to rotate. When the rotating shaft 315 drives the first crushing roller 316 to rotate, the slag powder is then put into the crushing box 312, so that the slag powder will fall between the first crushing roller 316 and the second crushing roller 317, and the slag powder lumps are crushed by the rotational friction between the outer walls of the first crushing roller 316 and the second crushing roller 317. The crushed slag powder will fall onto the screening plate 3110, and at the same time, the rotating shaft 315 will drive the rotating rod 3113 to rotate during the rotation. When the rotating rod 3113 rotates, it will contact and squeeze the connecting rod 3111, and the squeezed connecting rod 3111 will press the rubber plate 3112 is squeezed and deformed, and at the same time, one end of the screening plate 3110 is driven to rotate downward through the rotation of the rotating rod 319. When the rotating rod 319 rotates, it will also drive the torsion spring 318 to rotate. When the rotating rod 3113 continues to rotate and no longer contacts the connecting rod 3111, the torsion spring 318 will rebound and reset, driving the rotating rod 319 to reset and rotate, thereby driving the screening plate 3110 to rotate upward. This repeated action will drive the screening plate 3110 to rotate up and down, so that the slag powder lumps that have not been completely crushed can be shaken off to the bottom side of the screening frame 3110, and then the staff will collect the uncrushed slag powder and put it into the crushing box 312 for crushing again. The powdered slag powder will eventually fall into the air chute 2 for transportation.

[0035] When it is necessary to collect the slag powder lumps gathered on one side of the screening plate 3110, the dial plate 324 can be pushed upward to drive the baffle 323 to move upward on the inner wall of the slide 322, so that the discharge chute 321 can be opened, and the staff of the discharge chute 321 can collect the slag powder lumps. When the dial plate 324 moves to the top, it can contact the magnet 325 at the top and magnetically attract the dial plate 324 to limit the baffle 323.
