[0027] Please see Figure 1 and Figure 2 This utility model provides a technical solution: a metal silicon production anti-clogging crushing device, comprising...
[0028] The crushing mechanism 100 includes an anti-blocking mechanism 200, which is installed at the feed inlet of the crushing mechanism 100. The anti-blocking mechanism 200 includes an auxiliary feeding component 210, which includes a first fixed seat 211 and a second fixed seat 214. Side plates 212 are fixedly connected to both sides of the first fixed seat 211 and the second fixed seat 214. A displacement plate 215 is driven to the inner side of the first fixed seat 211, and an adjustment plate 213 is driven to the inner side of the second fixed seat 214. A feed inlet adjustment component 220 is driven between the first fixed seat 211 and the displacement plate 215, and a feed inlet adjustment component 230 is driven between the adjustment plate 213 and the second fixed seat 214. Through the transmission of the feed inlet adjustment component 220 and the feed inlet adjustment component 230, the displacement plate 215 and the adjustment plate 213 can adjust the falling path and speed of the material, preventing the material from accumulating at the feed inlet of the crushing mechanism 100, thereby effectively preventing blockage and improving production efficiency.
[0029] Please see Figures 1 to 3The crushing mechanism 100 includes a support frame 110, a drive mechanism 120 is provided above the support frame 110, the drive mechanism 120 is connected to a movable jaw plate 140, and a fixed jaw plate 130 is provided on the corresponding surface of the movable jaw plate 140. The crushing mechanism 100 is a jaw crusher.
[0030] Please see Figures 3 to 5 The first fixed seat 211 is a right-angled trapezoid and is fixedly installed above the fixed jaw plate 130. Side plates 212 are fixedly connected to both sides of the first fixed seat 211, and the other end of the side plates 212 is fixedly connected to both ends of the second fixed seat 214, which is L-shaped. A displacement plate 215 is fitted against the inclined surface of the first fixed seat 211. A guard plate 216 is fixedly connected to the top of the displacement plate 215, and the guard plate 216 is horizontally positioned on the top of the first fixed seat 211, with its sides located outside the side plates 212. An adjusting plate 213 is inclinedly positioned inside the second fixed seat 214. The adjusting plate 213 and the displacement plate 215 are arranged in an inverted V-shape to facilitate the entry of silicon metal and material feeding.
[0031] The feed inlet adjustment assembly 220 includes a mounting plate 221, which is located at the inner bottom of the first fixed seat 211. A lead screw 223 is driven and mounted on the upper part of the mounting plate 221, and a transmission plate 225 is driven and mounted on the upper part of the lead screw 223. The transmission plate 225 is connected to the displacement plate 215. A connecting rod 226 is fixedly connected to the back of the displacement plate 215 and slides through the mounting plate 221. The top of the transmission plate 225 is fixedly sleeved with the connecting rod 226. Positioning plates 222 are fixedly connected to the upper ends of the mounting plate 221, and the two ends of the lead screw 223 are respectively rotatably mounted on the inner side of the positioning plates 222. The bottom of the transmission plate 225 is connected to the lead screw 223, and the bottom surface of the transmission plate 225 is slidably connected to the upper surface of the mounting plate 221. The lead screw 223 is driven by a motor to drive the connecting rod 226 to push the displacement plate 215 to move, so as to change the distance between the displacement plate 215 and the bottom.
[0032] Slide rails 224 are fixedly installed on both sides of the bottom surface of the mounting plate 221. The inner bottom of the first fixed seat 211 is provided with a sliding groove that cooperates with the slide rails 224. A spring 229 is fixedly connected to the outer side of the positioning plate 222. When a large piece of metal silicon impacts the displacement plate 215, the spring 229 has a certain buffering effect. Because the first fixed seat 211 is slidably installed on the inner bottom of the first fixed seat 211 through the slide rails 224, the spring 229 can be replaced with other buffer devices or a damping spring.
[0033] The feed inlet adjustment assembly 230 includes an upper hinge block 231, which is fixedly mounted on the back of the adjustment plate 213. A hinge rod 233 is rotatably and through the upper hinge block 231. A lower hinge block 232 is rotatably and through the other side of the hinge rod 233. The lower hinge block 232 is fixedly connected to the second fixed seat 214. A hydraulic rod 234 is provided inside the second fixed seat 214 and on the back of the adjustment plate 213. The hydraulic rod 234 is hinged to the adjustment plate 213 and the second fixed seat 214, respectively. The hydraulic rod 234 is used to push the bottom of the adjustment plate 213 to flip it over, thereby adjusting its angle.
[0034] Working principle: The silicon metal material enters the crushing device through the feed port of the anti-blocking mechanism 200. At this time, the displacement plate 215 and the adjustment plate 213 are in the initial position, and the size and shape of the feed port are initially adjusted according to preset or actual needs.
[0035] The feed inlet adjustment assembly 220 is activated, and the motor drives the lead screw 223 to rotate. Since the transmission plate 225 is connected to the lead screw 223, and the bottom surface of the transmission plate 225 is slidably connected to the upper surface of the mounting plate 221, the rotation of the lead screw 223 causes the transmission plate 225 to move axially along the lead screw 223. The transmission plate 225 is fixedly connected to the displacement plate 215 via a connecting rod 226, thereby causing the displacement plate 215 to move horizontally on the inclined surface of the first fixed seat 211, thus adjusting the size of the feed inlet.
[0036] When the feed inlet adjustment assembly 230 is activated, the hydraulic rod 234 extends and retracts. Since the hydraulic rod 234 is hinged to the adjustment plate 213 and the second fixed seat 214 respectively, it will drive the adjustment plate 213 to rotate around the lead screw 223 between the upper hinge block 231 and the lower hinge block 232, thereby changing the tilt angle of the adjustment plate 213 and realizing the adjustment of the size of the feed inlet and the feed outlet.
[0037] After adjusting the feed inlet, the metallic silicon material falls into the crushing mechanism 100 at a suitable speed and path. The drive mechanism 120 drives the movable jaw plate 140 to perform periodic reciprocating oscillations. The movable jaw plate 140 and the fixed jaw plate 130 cooperate to apply extrusion pressure to the material, crushing the metallic silicon material into the required particle size. During the material's descent, the slide rail 224 on the bottom surface of the mounting plate 221 slides in the groove at the bottom of the first fixed seat 211. The spring 229 on the outer side of the positioning plate 222 acts as a buffer, reducing the impact of material impact on the equipment and ensuring stable operation of the equipment.
[0038] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
