Description

Technical Field

[0001] This utility model relates to the technical field of silicon micropowder processing equipment, specifically a high-efficiency composite silicon micropowder pulverizer. Background Technology

[0002] Currently, existing pulverizers, when processing larger or harder silicon micropowders, often fail to pulverize them completely or result in uneven particle sizes, with particles that are too large to meet production and usage requirements. Furthermore, the pulverizing process consumes a significant amount of energy, leading to excessively high production costs. Additionally, malfunctions or wear in components such as gears and rollers within the drive system can result in prolonged downtime and maintenance, further increasing equipment maintenance costs and downtime.

[0003] The lack of sieving after pulverization resulted in significant particle size inhomogeneity in the silicon micropowder, making it unsuitable for large-scale industrial production. The pulverizer also has limitations in precisely controlling particle size, particularly when processing ultrafine silicon micropowder, where achieving extremely fine particle sizes is difficult. Utility Model Content

[0004] In view of the shortcomings of the prior art and to solve the problems mentioned in the background art, the technical problem to be solved by this utility model is to provide a high-efficiency composite silicon micro powder pulverizer that can fully crush, automatically complete screening, and then quickly convey and transfer the powder.

[0005] The technical problem to be solved by this utility model is achieved through the following technical solution: a high-efficiency composite silicon micro powder pulverizer, including a main frame and a side frame. A pulverizing box is provided on the top of the main frame. The pulverizing box is equipped with a pulverizing roller assembly for pulverizing silicon micro powder. The pulverizing roller assembly includes a central driving roller and corresponding meshing driven rollers. Both the driving roller and the driven roller are annular groove cutting rollers with equal spacing. Half rollers that mesh with the driving roller and the driven roller are provided on the inner side wall of the pulverizing box. The driving roller, the driven roller, and the half rollers meshing on both sides are arranged to fill the entire cross-section of the pulverizing box, effectively pulverizing and grinding the silicon micro powder. The ground particles are fine and uniform, ensuring sufficient grinding. A drive motor that drives the driving roller to rotate is provided outside the pulverizing box. The shaft end of the drive motor is coaxially mounted with the driving roller. A drive gear is sleeved on the drive motor shaft. The drive gear meshes with a driven gear. The driven gears are respectively sleeved on the shaft ends of the driven rollers. The drive motor and the driving roller shaft are coaxially mounted. The drive motor transmits power through the drive gear and the driven gear to ensure synchronous movement and improve pulverizing efficiency and accuracy.

[0006] The bottom of the crushing box is equipped with a material discharge port, and directly below the material discharge port is a vibrating screen assembly. The vibrating screen assembly includes a vibrating screen with several screen holes evenly distributed on it. The diameter of the screen holes is consistent with the expected particle diameter of the crushed silicon micro powder. The crushed silicon micro powder is automatically screened to separate the silicon micro powder that meets the particle size requirements, thereby improving the precision of the finished product.

[0007] A discharge port is located below the vibrating screen, and a discharge cone is installed at the discharge port. Below the discharge cone is a conveying device for transferring silicon micropowder. Through the discharge port and discharge cone, the pulverized silicon micropowder flows smoothly out and is effectively and quickly transported to subsequent processing stages by the conveying device. Material residence time is minimal, ensuring smooth operation of the production line.

[0008] As a further embodiment of this invention, the vibrating screen assembly also includes a vibrating cylinder for driving the vibrating screen to reciprocate. The shaft end of the vibrating cylinder is connected to the vibrating screen via a connecting plate. The vibrating screen includes a screen plate and a vibrating frame surrounding the screen plate. A set of sliding components is arranged on both sides of the vibrating frame, each set including two sets of pulleys respectively on both sides of the vibrating frame. Each set of pulleys has a corresponding slide rail on its side, and each set of pulleys slides in cooperation with the corresponding slide rail. The vibrating cylinder provides effective power to drive the vibrating screen, and the slide rails and pulleys provide a stable sliding trajectory during movement, maintaining continuous and efficient vibration, improving the screening effect, and allowing the material to fall quickly after being screened.

[0009] As a further embodiment of this invention, the crushing chamber has positioning holes on its side wall. Inside the chamber, on the side of the drive motor, are vertically parallel first and second partitions. Both the first and second partitions have mounting holes. The first partition has a first mounting hole and second mounting holes symmetrically arranged on both sides of the first mounting hole.

[0010] As a further embodiment of this utility model, the drive motor shaft passes through the positioning hole, the first mounting hole and the second mounting hole in sequence and is fixedly installed at the end of the drive roller. A bearing is provided between the drive motor shaft and the first mounting hole and the second mounting hole, and a drive gear is provided on the drive motor shaft between the positioning hole and the first mounting hole.

[0011] The driven roller shaft is sequentially assembled with the second and fourth mounting holes via bearings. The driven gear is mounted on the driven roller shaft between the side wall of the crushing chamber and the first partition. This ensures sufficient power transmission, reduces friction through bearing engagement, and improves the meshing accuracy between the rollers.

[0012] As a further embodiment of this invention, the drive motor is mounted on a side bracket, which houses an electrical box containing a power supply and a controller. The power supply is electrically connected to both the drive motor and the vibrating cylinder, while the controller is connected to both the drive motor and the vibrating cylinder via signals.

[0014] As a further embodiment of this utility model, the discharge cone includes a large opening and a small opening, with the large opening connected to the discharge port and the small opening facing the conveying device.

[0015] As a further embodiment of this invention, the conveying device includes a remote conveyor belt, which is driven by a conveyor drive to move in one direction.

[0028] As shown in Figures 1-3, a high-efficiency composite silicon micro powder pulverizer includes a main frame 2 and a side frame 1. A pulverizing box 8 is provided on the top of the main frame. The upper opening of the pulverizing box is an open feed inlet, and a feed cone 801 is provided at the feed inlet, with the larger opening of the feed cone facing upwards. Large silicon micro powder particles to be ground fall into the pulverizing box along the feed cone.

[0029] The grinding chamber is equipped with a grinding roller assembly for grinding silicon micropowder. The assembly includes a central driving roller 9 and corresponding meshing driven rollers 901. Both the driving and driven rollers are equally spaced annular groove cutting rollers. Half-rollers 902, meshing with the driving and driven rollers respectively, are located on the inner sidewall of the grinding chamber. The annular groove cutting rollers have sequentially arranged annular cutters along their length. The annular cutters on the driving and driven rollers are staggered, forming annular grooves between the cutters. The dimensions of the annular cutters and the annular grooves match, and the gap between them creates a grinding space for the silicon micropowder. The grinding process is continuous as the driving and driven rollers rotate in opposite directions.

[0030] The active roller, driven roller, and meshing half-rollers on both sides cover the entire cross-section of the crushing chamber. A drive motor 12, which drives the active roller to rotate, is located outside the crushing chamber. The drive motor is mounted on a side support 1, which houses an electrical box 13. The electrical box contains a power supply and a controller. The power supply is electrically connected to the drive motor and the vibrating cylinder, and the controller is signal-connected to both the drive motor and the vibrating cylinder. The power supply provides power to the drive motor and the vibrating cylinder, and the controller controls the start and stop of the drive motor and the vibrating cylinder according to on-site requirements.

[0031] The drive motor shaft is coaxially mounted with the drive roller, and a drive gear 11 is sleeved on the drive motor shaft. The side wall of the crushing box is provided with a positioning hole. The first partition 802 and the second partition 803 are arranged vertically and parallel to each other on the side of the drive motor inside the box. Both the first partition and the second partition are provided with mounting holes. The first partition is provided with a first mounting hole and a second mounting hole symmetrically arranged on both sides of the first mounting hole. The second partition is provided with a third mounting hole and a fourth mounting hole symmetrically arranged on both sides of the third mounting hole. The positioning hole, the first mounting hole and the third mounting hole are arranged through each other. The second mounting hole and the fourth mounting hole are arranged through each other.

[0032] The drive motor shaft passes through the positioning hole, the first mounting hole and the second mounting hole in sequence and is fixedly installed at the end of the drive roller. A bearing is provided between the drive motor shaft and the first mounting hole and the second mounting hole. The drive gear is installed on the drive motor shaft between the positioning hole and the first mounting hole.

[0033] The drive gear meshes with a driven gear 10, which is respectively sleeved on the driven roller shaft end. The driven roller shaft end is sequentially assembled with the second mounting hole and the fourth mounting hole through bearings. The driven gear is installed on the driven roller shaft between the side wall of the crushing box and the first partition plate.

[0034] The drive motor 12 starts, driving the drive gear to rotate. The rotation of the drive gear 11 drives the driven gear 10 to rotate. The drive gear and the driven gear rotate in opposite directions to crush and grind the silicon micro powder. The gap between the drive roller and the driven roller is adjusted according to the required size of the silicon micro powder particles.

[0035] The bottom of the crushing chamber is equipped with a discharge port 7, which is a cone-shaped feed cylinder with a small opening facing downwards. The crushed silicon micropowder falls along the discharge port. Directly below the discharge port is a vibrating screen assembly, which includes a vibrating screen 603. The vibrating screen has several screen holes evenly distributed on it, and the diameter of the screen holes is consistent with the expected particle diameter of the crushed silicon micropowder. The crushed silicon micropowder falls onto the surface of the vibrating screen. Silicon micropowder particles with a diameter smaller than or equal to the screen holes fall along the screen holes. Silicon micropowder particles with a diameter larger than the screen holes remain on the vibrating screen for periodic transfer and cleaning.

[0036] The vibrating screen assembly 6 also includes a vibrating cylinder 601 that drives the vibrating screen to reciprocate. The shaft end of the vibrating cylinder is connected to the vibrating screen via a connecting plate 602. The vibrating screen includes a screen plate and a vibrating frame surrounding the screen plate. A set of sliding components 604 are arranged on both sides of the vibrating frame. The sliding components include two sets of pulleys respectively arranged on both sides of the vibrating frame. Each set of pulleys has a corresponding slide rail on its side, and each set of pulleys slides in cooperation with the corresponding slide rail. The main frame is also provided with a middle support plate. The discharge port is opened on the middle support plate. The vibrating cylinder is set on the middle support plate at one end of the discharge port. The two slide rails are symmetrically arranged along both sides of the discharge port.

[0037] Before the silicon powder falls onto the surface of the vibrating screen 603, the vibrating cylinder 601 is activated. The shaft of the vibrating cylinder drives the intermediate support plate, transmitting the reciprocating motion to the vibrating screen. The pulleys on both sides of the vibrating screen slide back and forth along the slide rail to achieve vibrating screening.

[0038] A discharge port is located below the vibrating screen, and a discharge cone 5 is provided at the discharge port. The discharge cone includes a large opening and a small opening. The large opening is connected to the discharge port, and the small opening is positioned directly opposite the conveying device. The small opening of the discharge cone concentrates the pulverized silicon powder before it falls, preventing it from dispersing and scattering.

[0039] Below the discharge cone is a conveying device 4 for transferring silicon micropowder. The conveying device includes a remote conveyor belt, which is driven by a conveyor drive to move in one direction. The width of the remote conveyor belt is larger than the small opening of the cone. After the conveyor drive is activated, the silicon micropowder falling onto the remote conveyor belt is continuously conveyed to the next process.

[0040] In this specification, the terms "connection," "installation," "fixing," and "setting" are interpreted broadly. For example, "connection" can mean a fixed connection or an indirect connection via intermediate components without affecting the relationship between components or the technical effect; it can also mean an integral connection or a partial connection. Those skilled in the art can understand the specific meaning of these terms in this utility model or utility model based on the specific circumstances. The above description is merely a preferred embodiment of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
