Description

Technical Field

[0001] This utility model relates to the technical field of steel waste treatment equipment, specifically to a crushing device for carbon steel production waste. Background Technology

[0002] During the smelting and processing of carbon steel, a large amount of solid waste is generated. This solid waste includes slag, steel slag, graphite powder, and carbon powder, among other particulate impurities. These wastes mix together to form irregular block structures. Since the iron in this waste can be recycled, it is necessary to crush the steel scrap to separate the iron. This waste is first transported to crushing equipment for processing. After being squeezed by crushing rollers, the waste is formed into small block structures. However, after crushing, some waste fragments develop cracks on their surface, but they are still stuck together and not completely separated. When these incompletely separated fragments are screened by a magnetic separator, some unwanted waste is also screened out, which affects the quality of the iron scrap recovered.

It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0022] like Figure 1-4 As shown in the figure, this utility model embodiment provides a crushing device for carbon steel production waste, including a crushing cylinder 1, a feed inlet 2 at the top of the crushing cylinder 1, a discharge outlet at the bottom of the crushing cylinder 1, a discharge channel 3 at the discharge outlet, two crushing rollers 4 with crushing teeth symmetrically arranged inside the crushing cylinder 1 below the corresponding feed inlet 2, the two crushing rollers 4 rotating in opposite directions, the crushing rollers 4 being driven to rotate by a motor, a vertical crusher being arranged inside the discharge channel 3, a slowing channel 5 being arranged at the bottom of the discharge channel 4, and a plurality of slowing belts 6 being evenly distributed inside the slowing channel 5, with gaps between each slowing belt 6.

[0023] The crusher includes a mounting crossbar 7 at the bottom of the discharge channel 3, a vertical pole 8 in the middle of the mounting crossbar 7, and several crushing blades 9 evenly distributed circumferentially from top to bottom on the upper end of the vertical pole 8.

[0024] The top of the mounting crossbar 7 is provided with a flow guide platform 10 with a triangular cross-section. The end of the flow guide platform 10 with a sharp corner is arranged upward. A clearance opening is provided on the flow guide platform 10 at the position corresponding to the upright 8. The lower end of the upright 8 passes through the clearance opening and is fixedly connected to the top of the mounting crossbar 7.

[0025] The top of the upright 8 is provided with a protruding spike structure 11.

[0026] The crushing blades 9 are arranged in a staggered manner along the circumference of the upright 8. One end of the crushing blades 9 is fixedly connected to the side wall of the upright 8, and the end of the crushing blades 9 away from the upright 8 is provided with protruding spikes.

[0027] The deceleration channel 5 has symmetrical clearance gaps 5a on both sides. The deceleration belt 6 extends outward along the clearance gaps 5a on both sides. The deceleration channel 5 has a mounting plate 12 below the corresponding clearance gaps 5a on both sides. The mounting plate 12 has a mounting platform 13. The end of the deceleration belt 6 extending outward from the deceleration channel 5 is fixed on the mounting platform 13.

[0028] A rotating shaft seat 14 is symmetrically arranged on the front and rear sides of the mounting plate 12 on one side. A rotating shaft 15 is arranged between the rotating shaft seats 14. A vibrating roller 16 is arranged on the outer side of the rotating shaft 15. The vibrating roller 16 is eccentrically connected to the rotating shaft 15, that is, the rotating shaft 15 is installed at a position off the central axis of the vibrating roller 16. In this way, when the rotating shaft 15 is driven to rotate, the vibrating roller 16 can move up and down. The vibrating roller 16 is located below the deceleration belt 6 and contacts the lower end face of the deceleration belt 6. When the vibrating roller 16 rotates, it will move up and down. In this way, the vibrating roller 16 will cause the deceleration belt 6 to vibrate, thus preventing the accumulation of broken waste material and its jamming on the deceleration belt 6.

[0029] A rotating handwheel 17 is provided at one end of the rotating shaft 15, and an operating lever 18 is provided on the rotating handwheel 17.

[0030] Inclined baffles 19 are provided on the inner walls of both sides of the crushing cylinder 1 above the corresponding crushing rollers 4, and the baffles 19 on both sides avoid the feed inlet 2.

[0031] The lower end of the crushing cylinder 1 has a constricted structure, and the discharge channel 3 is located at the lowest end of the constricted structure of the crushing cylinder 1.

[0032] The working principle of this utility model is as follows: After cooling, steelmaking waste is conveyed by a conveying device. The waste is fed into the crushing cylinder 1 through the feed inlet 2 at the top of the crushing cylinder 1. The two crushing rollers 4 are started to rotate, and the waste is crushed between the two crushing rollers 4. The crushed waste falls downward into the discharge channel 3. During the fall, the waste collides with the spike structure 11 at the top of the upright 8 and the crushing blades 9, thus performing secondary crushing on the already broken but not completely separated waste. The inclined surface of the guide table 10 prevents the crushed waste from accumulating on the mounting crossbar 7. Subsequently, the waste falls into the deceleration channel 5. After contacting the deceleration belt, the material can be decelerated to avoid generating a large amount of dust when the waste falls. The waste contacts the deceleration belt 6 and falls through the gap between the deceleration belts 6. The fallen waste falls along the opening at the lower end of the deceleration channel 5 onto the conveying equipment. Then, the waste is conveyed by the conveying equipment and then the iron material is magnetically collected by the magnetic separator. After the crushing and recycling operation is completed, the handwheel 17 can be manually rotated to control the up and down movement of the vibrating roller 16. The vibrating roller 16 contacts the deceleration belt 6 and causes the deceleration belt 6 to vibrate. In this way, the crushed material can fall on the deceleration belt 6, thus avoiding the accumulation of material.

Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
