Abstract
Description
Technical Field
[0001] This utility model relates to the field of mineral processing equipment technology, and in particular to a device for removing mica from quartz sand. Background Technology
[0002] High-purity quartz sand is a raw material for producing high-grade quartz products. Due to its excellent physicochemical properties, such as high temperature resistance, corrosion resistance, low thermal expansion, high insulation, and light transmittance, it is widely used in high-tech industries such as fiber optic communication, solar photovoltaics, aerospace, electronics, and semiconductors, holding a very important strategic position. The quartz sand used in the production of quartz crucibles requires a purity higher than 99.998%, therefore, mica in the quartz sand must be removed during the production process. Based on this, this application provides a low-cost and simple device for removing mica from quartz sand. Utility Model Content
[0003] To solve the above-mentioned technical problems, this utility model provides a device for removing mica from quartz sand, including a base, on which a vibrating leveling feeder, a conveying mechanism, and a receiver are arranged, wherein:
[0004] The discharge end of the vibratory leveling feeder is connected to the feed end of the conveying mechanism to transfer the quartz sand leveled by the vibratory leveling feeder to the conveying mechanism.
[0005] The discharge end of the conveying mechanism is connected to the inlet end of the receiver to transfer the received quartz sand to the receiver at a preset speed.
[0006] The receiver includes a mica receiver and a quartz receiver, with an adjusting baffle connecting the mica receiver and the quartz receiver, and the mica receiver is located on the side closer to the conveying mechanism.
[0007] In some embodiments, the vibratory leveling feeder includes a feed bin, a vibratory motor, and a spring. The feed bin is mounted on a base via the spring, and the vibratory motor is mounted at the bottom of the feed bin.
[0008] In some embodiments, the conveying mechanism includes a conveying motor, a drive shaft, a driven shaft, and a conveyor belt. The drive shaft and the driven shaft are rotatably connected to a base, and the conveyor belt is sleeved on the drive shaft and the driven shaft. The transmission end of the conveying motor is connected to the drive shaft to drive the drive shaft to rotate, and the conveying motor is an adjustable speed variable frequency motor.
[0009] In some embodiments, baffles are fixed on both sides of the conveyor belt to prevent quartz sand from falling off the conveyor belt during the conveying process.
[0010] In some embodiments, the adjusting baffle is rotatably connected between the mica receiver and the quartz receiver to adjust the tilt angle of the adjusting baffle.
[0011] In some embodiments, a buffer trough is also included, which is inclinedly disposed between the vibratory leveling feeder and the conveying mechanism to buffer the quartz sand feed transmitted to the conveying mechanism.
[0012] In some embodiments, a blower unit is also included, the outlet of which is located above the receiver.

[0014] In some embodiments, the base is fitted with casters with self-locking function at its bottom.
[0015] Compared with existing technologies, the device for removing mica from quartz sand provided in this application first uses a vibrating leveling feeder to level the input quartz sand into a single layer, thereby avoiding the stacking of multiple layers of quartz sand and providing a prerequisite for subsequent separation. Then, the quartz sand is conveyed to the top of the receiver by a conveying mechanism. After the quartz sand material leaves the conveying mechanism, it falls due to gravity. During the falling process, the quartz sand material is given a certain initial velocity by the conveying mechanism, and the quartz sand material moves in a parabolic motion. However, the mica in the quartz sand has a large wind resistance, and its forward travel distance is less than that of the quartz particles. By adjusting the conveying speed of the conveying mechanism and the position of the receiver, the mica and quartz in the quartz sand can be effectively separated. Therefore, the device for removing mica from quartz sand provided in this application effectively solves the technical problem of the difficulty in removing mica from quartz sand in the prior art, and has the characteristics of simple structure and low cost.

[0020] like Figure 1 As shown, the present invention provides a device for removing mica from quartz sand, comprising a base 1, on which a vibrating leveling feeder, a conveying mechanism, and a receiver are provided, wherein:
[0021] The discharge end of the vibratory leveling feeder is connected to the feed end of the conveying mechanism to transfer the quartz sand leveled by the vibratory leveling feeder to the conveying mechanism.
[0022] The discharge end of the conveying mechanism is connected to the inlet end of the receiver to transfer the received quartz sand to the receiver at a preset speed.
[0023] The receiver includes a mica receiver 41 and a quartz receiver 42. An adjusting baffle 43 is connected between the mica receiver 41 and the quartz receiver 42, and the mica receiver 41 is located on the side closer to the conveying mechanism.
[0024] In the above embodiment, the vibratory leveling feeder includes a feed bin 21, a vibratory motor 22, and a spring 23. The feed bin 21 is mounted on the base 1 via the spring 23, and the vibratory motor 22 is installed at the bottom of the feed bin 21. In this structure, the vibratory motor 22 is used to vibrate the feed bin 21, thereby achieving vibration leveling of the quartz sand in the feed bin 21 to a single layer.
[0025] In the above embodiment, the conveying mechanism includes a conveying motor 31, a drive shaft 32, a driven shaft 33, and a conveyor belt 34. The drive shaft 32 and the driven shaft 33 are rotatably connected to the base 1. The conveyor belt 34 is sleeved on the drive shaft 32 and the driven shaft 33. The transmission end of the conveying motor 31 is connected to the drive shaft 32 to drive the drive shaft 32 to rotate. The conveying motor 31 is an adjustable speed variable frequency motor. In this structure, the transmission between the drive shaft 32 and the driven shaft 33 is realized through the conveyor belt 34. The conveying motor 31 drives the drive shaft 32 to rotate, which in turn drives the driven shaft 33 to rotate. Consequently, the conveyor belt 34 drives the quartz sand material forward, thus realizing the conveying of the quartz sand material.
[0026] In the above embodiments, firstly, the input quartz sand is leveled into a single layer using a vibrating leveling feeder, thereby avoiding the stacking of multiple layers of quartz sand and providing a prerequisite for subsequent separation. Then, the quartz sand is conveyed to the top of the receiver by a conveying mechanism. After the quartz sand material leaves the conveying mechanism, it falls due to gravity. During the falling process, the conveying mechanism can provide the quartz sand material with a certain initial velocity, so the quartz sand material moves in a parabolic motion. However, the mica in the quartz sand has a large wind resistance, and its forward running distance will be less than that of the quartz particles. By adjusting the conveying speed of the conveying mechanism and the position of the receiver, the mica and quartz in the quartz sand can be effectively separated. Therefore, the device for removing mica from quartz sand provided in this application effectively solves the technical problem of the difficulty in removing mica from quartz sand in the prior art, and has the characteristics of simple structure and low cost.
[0027] In some embodiments, baffles are fixedly provided on both sides of the conveyor belt 34 to prevent quartz sand from falling off the conveyor belt 34 during the conveying process.
[0028] In the above embodiments, by setting baffles on the conveyor belt 34, the quartz sand can be effectively prevented from falling off the conveyor belt 34.
[0029] In some embodiments, the adjusting baffle 43 is rotatably connected between the mica receiver 41 and the quartz receiver 42 to adjust the tilt angle of the adjusting baffle 43.
[0030] In the above embodiments, by rotating the adjusting baffle 43 onto the receiver, the tilt angle between the adjusting baffle 43 and the mica receiver 41 or the quartz receiver 42 can be adjusted, which further ensures the effective separation of mica and quartz in quartz sand.
[0031] In some embodiments, a buffer trough 5 is also included, which is inclinedly disposed between the vibrating leveling feeder and the conveying mechanism to buffer the quartz sand feed transmitted to the conveying mechanism.
[0032] In the above embodiments, by setting buffer grooves 5 at the discharge end of the vibratory leveling feeder and the feed end of the conveying mechanism, the feed of the conveying mechanism can be buffered by the buffer grooves 5, providing a buffering effect for matching the feeding amount of the vibratory leveling feeder and the conveying amount of the conveying mechanism.
[0033] In some embodiments, a blower unit 6 is also included, the outlet of which is located above the receiver.
[0034] In the above embodiments, by setting up a blower unit 6 above the receiver, the wind force of the blower unit 6 is used to act on the quartz sand conveyed by the conveying mechanism, which further shortens the forward running distance of mica in the quartz sand, thereby providing a separation effect between mica and quartz in the quartz sand.
[0035] It should be noted that the blower unit 6 is a variable frequency blower with adjustable wind speed, which can adjust the wind speed of the variable frequency blower to adapt to different particle sizes of quartz sand material, effectively expanding the application range of the device.
[0036] In some embodiments, the base 1 is equipped with casters with self-locking function at its bottom.
[0037] In the above embodiments, by installing casters at the bottom of the base 1, the operator can easily move the device, reducing the operator's labor intensity.
[0038] The present invention provides a detailed description of a device for removing mica from quartz sand. Specific examples have been used to illustrate the principle and implementation of the present invention. The descriptions of these embodiments are merely for the purpose of helping to understand the core idea of the present invention. It should be noted that those skilled in the art can make various improvements and modifications to the present invention without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
