Description

Technical Field

[0001] This invention relates to the field of crushing equipment technology, and more specifically to a rapid crushing device for silicon material processing. Background Technology

[0002] Silicon, as a key basic material, has demonstrated broad application potential in the photovoltaic and semiconductor industries. To improve the processing efficiency of silicon materials, rapid crushing devices have emerged. In the field of crushing machinery, there are various crushing equipment, including jaw crushers, impact crushers, vertical shaft impact crushers, hydraulic cone crushers, ring hammer crushers, hammer crushers, roller crushers, compound crushers, cone crushers, two-stage crushers, gyratory crushers, and mobile crushers. These crushing devices each have unique designs and working principles, adapting to different crushing needs and production environments. For example, jaw crushers are widely used in the coarse crushing stage due to their simple structure and durability; impact crushers are favored by the market due to their high crushing ratio and good particle shape; and vertical shaft impact crushers occupy a place in the fine crushing field due to their high efficiency and low energy consumption. Each type of crushing equipment has its specific application scenarios and advantages; therefore, selecting the appropriate crushing equipment is crucial for improving production efficiency and reducing production costs.

[0003] Inadequacies of Existing Technology: Existing crushing devices often suffer from screen clogging when processing silicon materials due to excessive material moisture and insufficient crushing force, leading to incomplete material crushing. Screen clogging not only reduces crushing efficiency but also increases equipment load and may even cause equipment damage.

The bottom ends of the ridge plate are fixedly connected to buffer springs. The two ends of the ridge plate are movably connected to the inner wall platform of the crushing device shell through the buffer springs. A shaft is provided at the bottom of the ridge plate. One end of the shaft is rotatably connected to the inner wall of the crushing device shell, and the other end is fixedly connected to a small motor through the wall of the crushing device shell. A set of primary vibration blocks and a set of secondary vibration blocks are symmetrically arranged on the outer periphery of the shaft, wherein the rotation radius of the secondary vibration blocks is smaller than that of the primary vibration blocks.

[0006] Furthermore, symmetrically arranged transverse screen bars are fixedly connected to both sides of the ridge plate. The transverse screen bars extend obliquely downwards to both sides of the ridge plate, with a pressure plate fixedly connected to their bottom ends. The transverse screen bars are linearly distributed along the ridge plate. A slide rail is fixedly connected to the bottom end of the transverse screen bars. A sliding sleeve is slidably connected to the bottom end of the slide rail. A longitudinal screen bar is fixedly connected to the bottom end of the sliding sleeve. The longitudinal screen bars are linearly distributed radially along the sliding sleeve. Mounting grooves that fit the bottom end of the sliding sleeve are opened at the top of both ends of the longitudinal screen bars.

[0007] Furthermore, the transverse screen bar and the longitudinal screen bar together form a screen with a fixed aperture.

[0008] Furthermore, the misalignment component includes a transmission column linearly distributed along the transverse screen bar. The inclined surface at the top of the transmission column is parallel to the bottom surface of the transverse screen bar, and the width of the transmission column is smaller than the gap between the longitudinal screen bars. A slide block is fixedly connected to the bottom end of the transmission column. A slide rail is movably connected inside the slide block. Stops are fixedly connected to both ends of the slide rail. A return spring is fixedly connected to one end of the stop block near the ridge plate. The other end of the return spring is fixedly connected to the end face of the slide block. The misalignment component is distributed at both ends of the longitudinal screen bar and is symmetrical about the ridge plate.

[0009] Furthermore, a rack is fixedly connected to the end of the slide away from the ridge plate, the rack meshes with a gear seat, a threaded hole is opened at the axis of the gear seat, a screw is threadedly connected to the threaded hole, a top plate is rotatably connected to the top of the screw, a first spring is sleeved on the outer periphery of the screw, a protective sleeve is slidably connected to the outer periphery of the top plate, the gear seat is rotatably connected inside the protective sleeve, and the bottom end of the protective sleeve is fixedly connected to the top of the discharge assembly.

[0010] Furthermore, the horizontal screen plate includes a second transverse screen bar and a pressure groove formed at the top of the second transverse screen bar, wherein the pressure groove can engage with a pressure plate.

[0011] Furthermore, the discharge assembly includes a base fixedly connected to the bottom end of the sheath, and a discharge groove is provided through the top of the base, with a guide plate fixedly connected to the groove wall.

[0012] Furthermore, the feeding assembly includes an interface fixedly connected to the top of the crushing device housing, a feed inlet fixedly connected to the top of the interface, a movable cover plate movably connected to the feed inlet via a hinge, and a baffle fixedly connected to the bottom of the interface. An external plate for supporting the drive mechanism is fixedly connected to one side of the crushing device housing via triangular steel. A motor bracket for fixing the motor is fixedly connected to the top of the external plate. A grinding roller is provided inside the crushing device housing.

[0013] The technical effects and advantages of this invention are as follows: This invention utilizes a main vibration assembly, driven by a motor-driven shaft, to rotate primary and secondary vibration blocks. The rotation radius of the secondary vibration block is ensured to be smaller than that of the primary vibration block. In a non-blocked state, the primary vibration block strikes the ridge plate, causing it to vibrate. In a blocked state, the ridge plate sinks into the rotation radius of the secondary vibration block, triggering secondary vibration and increasing its frequency. This causes material accumulated on the screen plate to bounce up, allowing materials of the correct particle size to pass through more quickly. Materials with excessively large particle sizes are bounced up and re-engage with the grinding rollers for secondary crushing. This design automatically adjusts the screen plate vibration state according to the blockage situation, improving material screening and crushing efficiency while reducing the risk of blockage.

[0014] This invention converts the up-and-down vibration of the transverse screen bar into a short-distance reciprocating motion of the longitudinal screen bar along the transverse screen bar by setting up a misaligned component. By utilizing the relative displacement generated by the two, the material attached to the intersection of the two is effectively scraped off, thereby further accelerating the speed at which the material passes through the screening mechanism and improving the anti-clogging performance of the screening mechanism.

[0015] This invention, by incorporating a secondary vibration component, transforms the reciprocating motion of the misalignment component into a regular impact on the horizontal screen plate, causing it to vibrate rhythmically. This bounces up the material accumulated on the horizontal screen plate, allowing material of the correct particle size to pass through the screen plate more quickly. Simultaneously, oversized material, after being bounced up, repeatedly collides with the inner wall of the crushing device, achieving secondary crushing and improving material crushing efficiency. Furthermore, the secondary vibration component is powered by the misalignment component, which in turn relies on the drive of the main vibration component. This coordinated operation among the components reduces overall system energy consumption and improves the equipment's energy utilization rate. Attached Figure Description

[0020] Reference Figures 1 to 4 The present invention provides a rapid crushing device for silicon material processing, including a crushing device shell 1, a feeding component 2 fixedly connected to the top of the crushing device shell 1, a driving mechanism 3 provided on the side of the crushing device shell 1, a screening mechanism 4 provided inside the crushing device shell 1, and a discharge component 5 fixedly connected to the bottom of the crushing device shell 1. The screening mechanism 4 includes a ridge plate 41 movably connected to the inner wall of the crushing device housing 1, a main vibration assembly 42 rotatably connected to the inner wall of the crushing device housing 1, an inclined screen plate 43 fixedly connected to both sides of the ridge plate 41, a misalignment assembly 44 symmetrically arranged about the ridge plate 41, a secondary vibration assembly 45 movably connected to one end of the misalignment assembly 44, and a horizontal screen plate 46 arranged at the top of the secondary vibration assembly 45. The bottom ends of the ridge plate 41 are fixedly connected with buffer springs 411. The two ends of the ridge plate 41 are movably connected to the inner wall platform of the crushing device housing 1 through the buffer springs 411. The bottom of the ridge plate 41 is provided with a shaft 421. One end of the shaft 421 is rotatably connected to the inner wall of the crushing device housing 1, and the other end is fixedly connected to a small motor 422 through the wall of the crushing device housing 1. A set of primary vibration blocks 423 and a set of secondary vibration blocks 424 are symmetrically arranged and fixedly connected to the outer periphery of the shaft 421. The rotation radius of the secondary vibration blocks 424 is smaller than the rotation radius of the primary vibration blocks 423.

[0021] Reference Figures 3 to 5 A symmetrically arranged transverse screen bar 431 is fixedly connected to both sides of the ridge plate 41. The transverse screen bar 431 extends diagonally downward to both sides of the ridge plate 41 with the axis of the ridge plate 41 as the starting point. The bottom end of the extension is fixedly connected to a pressure plate 436. The transverse screen bar 431 is linearly distributed along the ridge plate 41. The bottom end of the transverse screen bar 431 is fixedly connected to a slide rail 432. The bottom end of the slide rail 432 is slidably connected to a sliding sleeve 433. The bottom end of the sliding sleeve 433 is fixedly connected to a longitudinal screen bar 434. The longitudinal screen bar 434 is linearly distributed radially along the sliding sleeve 433. The top of both ends of the longitudinal screen bar 434 is provided with mounting grooves 435 that are adapted to the bottom end of the sliding sleeve 433.

[0022] Among them, the transverse sieve bar 431 and the longitudinal sieve bar 434 constitute a sieve with a fixed aperture.

[0023] Reference Figure 6The misalignment component 44 includes a transmission column 441 linearly distributed along the transverse screen bar 431. The top inclined surface of the transmission column 441 is parallel to the bottom surface of the transverse screen bar 431, and the width of the transmission column 441 is smaller than the gap of the longitudinal screen bars 434. A slide block 442 is fixedly connected to the bottom end of the transmission column 441. A slide rail 443 is movably connected inside the slide block 442. Both ends of the slide rail 443 are fixedly connected to blocks. A return spring 444 is fixedly connected to one end of the block near the ridge plate 41. The other end of the return spring 444 is fixedly connected to the end face of the slide block 442. The misalignment component 44 is distributed at both ends of the longitudinal screen bar 434 and is symmetrical about the ridge plate 41. When the transmission column 441 moves toward the ridge plate 41, the return spring 444 is compressed.

[0024] Reference Figure 7 A rack 445 is fixedly connected to one end of the slide block 442 away from the ridge plate 41. The rack 445 meshes with a gear seat 451. A threaded hole 452 is provided at the axis of the gear seat 451. A screw 453 is threadedly connected to the threaded hole 452. A top plate 454 is rotatably connected to the top of the screw 453. A first spring 455 is sleeved on the outer periphery of the screw 453. A protective sleeve 456 is slidably connected to the outer periphery of the top plate 454. The gear seat 451 is rotatably connected inside the protective sleeve 456. The bottom end of the protective sleeve 456 is fixedly connected to the top of the discharge assembly 5. The movement of the rack 445 drives the gear seat 451 to rotate, thereby causing the screw 453 to move up and down. The up and down movement of the screw 453 pushes the top plate 454 to slide inside the protective sleeve 456. The vertical bars on both sides of the top plate 454 vertically restrict its movement inside the protective sleeve 456.

[0025] Reference Figure 8 The horizontal screen plate 46 includes a second transverse screen bar 461 and a pressure groove 462 formed at the top of the second transverse screen bar 461. The pressure groove 462 can be engaged with the pressure plate 436. When the horizontal screen plate 46 is vibrated by the secondary vibration component 45, its upward movement is restricted by the pressure plate 436. This design avoids the horizontal screen plate 46 from shifting due to violent vibration. However, since its upward path is cut off midway, the material on the surface of the horizontal screen plate 46 will be thrown out at a faster speed due to inertial force.

[0026] Reference Figure 9 The discharge assembly 5 includes a base 51 fixedly connected to the bottom of the sheath 456. A discharge trough is opened through the top of the base 51, and a guide plate 52 is fixedly connected to the wall of the trough. The qualified particle size material of the screening mechanism 4 passes through the discharge trough and is output along the guide plate 52.

[0027] Reference Figure 1 and Figure 2The feeding assembly 2 includes an interface 21 fixedly connected to the top of the crushing device housing 1, a feed inlet 22 fixedly connected to the top of the interface 21, a movable cover plate 23 movably connected to the feed inlet 22 via a hinge, and a baffle 24 fixedly connected to the bottom of the interface 21. Material is fed in from the feed inlet 22. During operation, the cover plate 23 is opened, and the baffle 24 is used to regulate the falling path of the material, so that the material is concentrated in the working area of ​​the roller surface and avoids material accumulation in the roller gap.

[0028] One side of the crushing device housing 1 is fixedly connected to an outer plate 11 for supporting the drive mechanism 3 via a triangular steel 12. The top of the outer plate 11 is fixedly connected to a motor bracket 32 ​​for fixing the motor. Inside the crushing device housing 1, there is a grinding roller 31. The surface of the grinding roller 31 is inlaid with roller nails made of high wear-resistant hard alloy to increase friction, bite into materials, and protect the roller body.

[0029] Working principle of the invention: Under normal operating conditions, the small motor 422 drives the shaft 421 to rotate, which in turn drives the first-stage vibrating block 423 to rotate, thus regularly striking the spine plate 41. This causes the spine plate 41 to vibrate regularly, which in turn causes the inclined screen plate 43 and the horizontal screen plate 46 to vibrate, accelerating the passage of the crushed qualified material.

[0030] When material gets stuck at screening mechanism 4, the accumulated material presses down the spine plate 41, inclined screen plate 43 and horizontal screen plate 46 as a whole. The descending spine plate 41 enters the rotation radius of the secondary vibrating block 424. At this time, the primary vibrating block 423 and the secondary vibrating block 424 driven by the small motor 422 strike the spine plate 41 alternately during rotation, so that the spine plate 41 gets a vibration frequency twice that of the initial frequency, that is, secondary vibration is achieved. At this time, the inclined screen plate 43 and the horizontal screen plate 46 vibrate more violently, which bounces up the material accumulated on the screen plate, so that the material with qualified particle size passes through faster, and the material with excessive particle size is bounced up and comes into contact with the grinding roller 31 again, resulting in secondary crushing.

[0031] The downward movement of the inclined screen plate 43 during the secondary vibration triggers the misalignment component 44. The specific working principle is as follows: Since the inclined surface of the top of the transmission column 441 is parallel to the inclined bottom surface of the transverse screen bar 431, and each vibration of the inclined screen plate 43 during the secondary vibration process includes both an upward and a downward movement, the downward movement allows the top of the transmission column 441 to insert into the gap of the longitudinal screen bar 434. Under continuous pressure, its top inclined surface can tilt upwards along the bottom surface of the transverse screen bar 431. Regarding the sliding, it needs to be further explained that the slide block 442, which is fixedly connected to the bottom end of the transmission column 441, slides along the slide rail 443 towards the ridge plate 41 during this process. In addition, since the longitudinal screen bar 434 is slidably connected to the transverse screen bar 431 through the sliding sleeve 433 and the slide rail 432, when the transmission column 441 slides along the bottom surface of the transverse screen bar 431 in an upward direction, the top end of the transmission column 441 will simultaneously push the longitudinal screen bar 434 and the transverse screen bar 431 to undergo relative displacement. When the inclined screen plate 43 moves upward due to the impact of the main vibration component 42, the top of the transmission column 441 disengages from the gap of the longitudinal screen bar 434. The longitudinal screen bar 434 loses the thrust of the transmission column 441 and slides down the slide rail 432 to the initial position under the action of gravity, completing one interlacing motion with the transverse screen bar 431. Similarly, the transmission column 441 loses the limit of the longitudinal screen bar 434 and returns to the initial position under the action of the elastic restoring force of the return spring 444, waiting for the next vibration of the inclined screen plate 43. The interlacing motion of the longitudinal screen bar 434 and the transverse screen bar 431 can effectively scrape off the material attached to the intersection of the two, thereby further accelerating the process of the material passing through the screening mechanism 4 and significantly improving the anti-clogging performance of the screening mechanism 4.

[0032] The misalignment component 44 converts the vibration of the inclined screen plate 43 into a reciprocating motion of the transmission column 441, i.e., a reciprocating motion of the slide 442. A rack 445 is fixedly connected to one end of the slide 442 near the side wall of the crushing device housing 1. The rack 445 and the slide 442 reciprocate synchronously. During the reciprocating motion of the rack 445, the gear seat 451 meshing with it rotates in the forward and reverse directions, causing the screw 453, which is threadedly connected to the threaded hole 452 at the shaft center of the gear seat 451, to move up and down repeatedly. The top plate 454, which is rotatably connected to the top of the screw 453, continuously strikes the horizontal screen plate 46, causing the horizontal screen plate 46 to vibrate. This can bounce up the material accumulated on the screen plate, allowing the material of qualified particle size to pass through faster, while the material with excessively large particle size is bounced up and repeatedly collides with the inner wall of the crushing device housing 1, resulting in secondary crushing.

[0033] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
