Description

Technical Field

[0001] The utility model relates to the technical field of industrial silicon processing, in particular to an industrial silicon crushing and screening machine. Background Art

[0002] Industrial silicon, also known as metallic silicon, is a product smelted in an electric furnace using silica as raw material and carbonaceous raw materials as reducing agents. The main component, silica (usually in the form of quartz or pebbles), is reduced by a carbonaceous reducing agent (washed coal, petroleum coke, charcoal, etc.) in an ore-fired furnace. Silicon ore is the most important raw material for industrial silicon smelting, which is mainly a general term for vein quartz, quartzite, and quartz sandstone. Pure silica can be used to make quartz glass or refine single crystal silicon. The appearance of crystalline silica is generally milky white, grayish white, light yellow, and reddish brown.

[0003] At present, the existing device (such as patent number: CN218013039U) discloses a fast crushing and screening machine, which designs a screen plate at the top of the installation box, so that the screen plate can directly screen the initial stones, and only unqualified stones will enter the crushing roller for crushing, while qualified stones will be directly sent out for use, thus saving a lot of time, increasing efficiency, and avoiding the problem of poor crushing effect of all stones at the same time in the prior art;

[0004] However, in the process of implementing the above technical scheme, it was found that there are at least the following technical problems: there is a large distance between the crushing roller of the device and the crushing chamber in the installation box, which will result in that when some industrial silicon is crushed, the broken industrial silicon will fall directly after being hit by the crushing roller. Since the shapes of industrial silicon are different, the sizes of industrial silicon after being hit by the crushing roller are also different each time. The volumes of the broken industrial silicon are uneven and the qualified rate is poor. Therefore, the device must be crushed multiple times, the efficiency is low, and the practicality needs to be improved. Utility Model Content

[0025] The embodiment of the present application effectively solves the technical problem of insufficient practicality of the existing device by providing an industrial silicon crushing and screening machine. By setting a feed guide plate, the arc-shaped guide plate can make the industrial silicon that is initially crushed by the first crushing roller play a gathering and conveying effect during the downward conveying process and fall between the second crushing rollers. At the same time, since the second crushing roller is located between the feed guide plates, secondary crushing can be completed, thereby improving the qualified rate of subsequent screen screening. By setting a synchronous belt, the second crushing roller can be driven to rotate when the motor drives the first crushing roller to rotate, thereby achieving secondary crushing while saving energy, which is more practical. By opening a through groove on the arc guide plate according to the second crushing wheels on the two second crushing rollers, the distance between the arc guide plate and the second crushing wheel can be minimized to the maximum extent, so that the distance between the second crushing roller and the arc guide plate is a negative distance, thereby greatly preventing unqualified industrial silicon from falling to the vibration screening unit through the gap between the second crushing roller and the through groove, thereby increasing the screening difficulty of the vibration screening unit and improving the overall processing qualified rate of the device.

[0026] Example

[0027] like Figure 1-Figure 5 As shown, the technical solution in the embodiment of the present application effectively solves the technical problem of insufficient practicality of the existing device, and the overall idea is as follows:

[0028] In view of the problems existing in the prior art, the utility model provides an industrial silicon crushing and screening machine, comprising a crushing and screening machine body 11, a control unit 12 is provided on the surface of the crushing and screening machine body 11, a discharge port 13 is provided on the side wall of the crushing and screening machine body 11, a feed guide plate 14 is symmetrically fixedly installed inside the crushing and screening machine body 11, and two feed guide plates 14 are partially exposed above the crushing and screening machine body 11, a motor 15 is symmetrically fixedly installed on the side wall of the crushing and screening machine body 11, and first crushing rollers 16 are fixedly installed on the output shafts of the two motors 15, and the two first crushing rollers 16 are partially exposed outside the crushing and screening machine body 11, and a plurality of first crushing wheels 17 are provided on the circumferential surface of the two first crushing rollers 16, and the first crushing wheels 17 on the two first crushing rollers 16 are staggered with each other;

[0029] An energy-saving guided secondary crushing mechanism is symmetrically fixedly installed inside the crushing and screening machine body 11;

[0030] The energy-saving guided secondary crushing mechanism includes an arc guide plate 18, and the two arc guide plates 18 are both located below the first crushing roller 16. A plurality of through grooves 19 are provided inside the two arc guide plates 18. The energy-saving guided secondary crushing mechanism also includes a second crushing roller 21, a second crushing wheel 22 and a synchronous belt 23. By setting the feed guide plate 14, the arc guide plate 18 can make the industrial silicon that is initially crushed by the first crushing roller 16 play a gathering and conveying effect during the downward conveying process and fall between the second crushing rollers 21. At the same time, since the second crushing roller 21 is located between the feed guide plates 14, the secondary crushing can be completed, thereby improving the qualified rate of subsequent screen screening. Moreover, by setting the synchronous belt 23, the motor 15 can be used to drive the first crushing roller 16 to rotate, and the second crushing roller 21 can be driven to rotate at the same time, thereby achieving secondary crushing in an energy-saving manner, which is more practical.

[0031] The two second crushing rollers 21 are both rotatably installed inside the crushing and screening machine body 11, and the two second crushing rollers 21 are partially exposed outside the crushing and screening machine body 11. The parts of the two first crushing rollers 16 and the second crushing rollers 21 exposed outside the crushing and screening machine body 11 are on the same side. The two second crushing rollers 21 are both located between the arc guide plates 18, and the centers of the two second crushing rollers 21 are parallel to the bottom of the arc guide plates 18. Each second crushing wheel 22 is arranged on the circumferential surface of the second crushing roller 21. The second crushing wheels 22 on the two second crushing rollers 21 are staggered with each other. The through grooves 19 on the two arc guide plates 18 are opened by the second crushing wheels 22 on the two second crushing rollers 21, and each second crushing wheel 22 is adapted to the through groove 19. The two synchronous belts 23 are both located on the second crushing rollers 21. It is rotatably installed between the first crushing roller 16, and limiting rings 24 are fixedly installed on the side walls of the two second crushing rollers 21 and the first crushing roller 16. A vibration screening unit 25 is provided inside the crushing and screening machine body 11, and the vibration screening unit 25 is located between the second crushing rollers 21 and the discharge port 13. By opening a through groove 19 on the arc guide plate 18 according to the second crushing wheels 22 on the two second crushing rollers 21, the distance between the arc guide plate 18 and the second crushing wheel 22 can be minimized, so that the distance between the second crushing roller 21 and the arc guide plate 18 is a negative distance, which can greatly prevent unqualified industrial silicon from falling to the vibration screening unit 25 through the distance between the second crushing roller 21 and the through groove 19, thereby increasing the screening difficulty of the vibration screening unit 25 and improving the overall processing qualification rate of the device.

[0032] Working principle:

[0033] The first step is that when using, the staff can start the motor 15 and the vibration motor of the vibration screening unit 25 in advance through the control unit 12. At this time, the two motors 15 and the first crushing roller 16 will respectively drive the first crushing rollers 16 connected to them to rotate forward and reverse as a whole. Then, the industrial silicon to be processed can be transported to the inside of the crushing and screening machine body 11 by a forklift. At this time, the industrial silicon will approach between the two first crushing wheels 17 due to the feed guide plate 14. At this time, the first crushing wheel 17 on the first crushing roller 16 will perform the initial crushing of the industrial silicon;

[0034] In the second step, the industrial silicon after the initial crushing will fall between the arc-shaped guide plates 18. At the same time, since the synchronous belt 23 is located between the second crushing roller 21 and the first crushing roller 16, the rotation of the first crushing roller 16 will drive the second crushing roller 21 to rotate together, and then the second crushing roller 21 drives the second crushing wheel 22 to rotate inside the crushing and screening machine body 11 and perform secondary crushing on the first crushing wheel 17 after the initial crushing. At the same time, by setting the through groove 19, the distance between the second crushing roller 21 and the arc-shaped guide plate 18 can be kept at a negative distance, thereby ensuring the secondary crushing effect of the second crushing roller 21 on the industrial silicon. Subsequently, the secondary crushed industrial silicon will fall into the vibration screening unit 25 for screening, and finally discharged through the discharge port 13.

[0035] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
