Description

Technical Field

[0001] This invention relates to the field of quartz sand impurity removal technology, specifically a device and method for removing impurities from high-purity quartz sand at high temperature. Background Technology

[0002] High-purity quartz sand refers to quartz sand with a SiO2 purity greater than 99.99%. It is a raw material for producing high-grade quartz products. Due to its excellent physical and chemical 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 optical fiber communication, solar photovoltaic, aerospace, electronics and semiconductors, and its strategic position is very important.

[0003] Our current high-purity quartz sand purification methods are based on the following principles: 1) Ore source: high purity, with silica content reaching over 99%; 2) Coarse processing: crushing, scrubbing, gravity separation, magnetic separation, flotation, calcination + water quenching; 3) Deep processing: acid leaching, roasting, high-temperature chlorination, etc. However, for specific quartz ore sources, the above conventional processing methods cannot remove certain impurities. These impurities will cause the purity to fall short of the highest level. Furthermore, although they cannot be identified by the naked eye in quartz sand, they appear as impurity points after melting in the molten quartz products, especially in quartz crucibles produced by electric arc method. Therefore, a device for removing impurities from high-purity quartz sand at high temperature is provided (see patent number: CN202110421867.4 for details). The device includes: a container with an inlet and a outlet; and a flame generating device located inside the container and between the inlet and the outlet. The flame generating device is used to emit a flame to burn the high-purity quartz sand entering from the inlet, thereby removing low-melting-point impurities from the high-purity quartz sand.

[0004] However, some existing high-temperature devices for removing impurities from high-purity quartz sand are unable to effectively remove impurities from the quartz sand during use, resulting in a decrease in the yield of quartz sand. Furthermore, the collection of impurities from quartz sand is also quite troublesome, making them impractical. In addition, some high-temperature devices for removing impurities from high-purity quartz sand inevitably leave some small particles of impurities inside the quartz sand during the impurity removal process. However, without a filtration device to remove them, this often leads to clogging of the filter plates, greatly increasing the cleaning work. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing high-temperature devices for removing impurities from high-purity quartz sand. These devices often fail to effectively remove impurities, leading to a decrease in quartz sand yield and cumbersome impurity collection, resulting in poor practicality. Furthermore, some high-temperature devices inevitably leave small particles of impurities inside the quartz sand during the removal process, which are not removed by a filtration system and often cause filter clogging, significantly increasing cleaning difficulties. This invention provides a device and method for high-temperature impurity removal from high-purity quartz sand.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a device for removing impurities from high-purity quartz sand at high temperature, comprising:

[0007] The main body of the device is used to support and protect the components required for removing impurities from high-purity quartz sand at high temperatures;

[0008] The impurity removal components are located inside the device body and extend to both sides outside the device body;

[0009] The filter assembly is located at the bottom of the impurity removal assembly and at the bottom of the device body.

[0010] The impurity removal assembly includes a combustion chamber, with flame-spraying devices on both sides of the bottom of the combustion chamber. Each of the two sets of flame-spraying devices has an impurity outlet at its bottom. Each of the two sets of impurity outlets has a fan on the side away from the combustion chamber. Each of the two sets of impurity outlets has a waste collection box at its bottom. The filter assembly includes a filter plate, with a funnel at its bottom. A fixing frame is provided on the outside of the filter plate. Telescopic rods are provided at the four corners of the bottom of the fixing frame. Springs are provided on the outside of the four sets of telescopic rods. Vibration devices are provided at the four corners inside the fixing frame.

[0011] As a further embodiment of the present invention: the device body includes a housing, the top of the housing is provided with a feed inlet, the inside of the feed inlet is provided with a solenoid valve, and the bottom of the housing is provided with a discharge outlet.

[0012] As a further embodiment of the present invention, the four corners of the bottom of the outer casing are provided with support feet.

[0013] As a further embodiment of the present invention: both sets of waste collection boxes are provided with handles on the side away from the funnel, both sets of waste collection boxes are provided with supports at the bottom, and both sets of waste collection boxes are supported and connected to the outer shell through the supports.

[0014] As a further embodiment of the present invention: the fixing frame is elastically connected to the outer shell by four sets of springs and telescopic rods.

[0015] As a further embodiment of the present invention: a sealing ring is provided on the outer side of the fixing frame, and a sliding groove is provided on the outer side of the sealing ring; the fixing frame is sealed and connected to the funnel through the sealing ring and the sliding groove.

[0016] As a further aspect of the present invention: the method for removing impurities from high-purity quartz sand at high temperature specifically includes the following steps:

[0017] Step 1: When using the device, first ensure the integrity of each component, and then support the device with the legs.

[0018] Step 2: Start the device, open the solenoid valve, and feed the quartz sand into the device through the feed port;

[0019] Step 3: Simultaneously, the flame-spraying device is activated, and the quartz sand falls into the combustion chamber. The impurities inside the quartz sand are heated and burned by the flames sprayed from the flame-spraying device, and the two sets of blowers are powered on and started to generate wind, which is blown into the device through the two sets of impurity outlets, blowing the clean and filtered quartz sand to the middle position of the filter plate.

[0020] Step 4: The purified quartz sand falls onto the surface of the filter plate. At the same time, the four sets of vibration devices are powered on and start to vibrate. The fixed frame also vibrates. Through the spring and telescopic rod, the vibration amplitude of the fixed frame is increased to filter and remove impurities from the quartz sand more quickly. The sealing ring on the outside of the fixed frame slides in the groove to prevent other impurities from entering the funnel.

[0021] Step 5: The filtered and impurity-removed quartz sand falls into the funnel and is discharged through the outlet at the bottom of the funnel.

[0022] Step Six: The solidified impurity blocks are then dislodged by the vibration of the fixed frame and fall into the two sets of impurity outlets. They are then collected in the two sets of waste collection boxes at the bottom of the two sets of impurity outlets. When the waste collection boxes are full, they are lifted by the handles and the waste is processed to complete the impurity removal work of the quartz sand.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] 1. The set impurity removal components activate the flame-spraying device, and the quartz sand falls into the combustion chamber. Impurities inside the quartz sand are heated and burned by the flames sprayed from the flame-spraying device, causing them to clump together. At the same time, two sets of fans are powered on and start up, generating airflow that blows into the device through two sets of impurity outlets. The heated and solidified impurity clumps fall into the two sets of impurity outlets and are collected in two sets of waste collection boxes at the bottom of the two sets of impurity outlets. When the waste collection boxes are full, they are lifted by the handles, and the waste is processed, completing the impurity removal work of the quartz sand. High temperature can remove other impurities in the quartz sand, and the airflow from the fans makes the heating more uniform, making the removal of impurities more thorough.

[0025] 2. Through the set filter components, the cleaned and filtered quartz sand is blown to the middle position of the filter plate. The impurity-removed quartz sand falls onto the surface of the filter plate. At the same time, four sets of vibration devices are powered on and start vibrating, and the fixed frame also vibrates. Through springs and telescopic rods, the vibration amplitude generated by the fixed frame is increased to filter and remove impurities from the quartz sand more quickly. The sealing ring on the outside of the fixed frame slides in the groove to prevent other impurities from entering the funnel. The filtered and impurity-removed quartz sand falls into the funnel and is discharged through the discharge port at the bottom of the funnel. It can filter and remove small impurity clumps inside the quartz sand after impurity removal. At the same time, the vibration reduces the accumulation and clogging of quartz sand on the surface of the filter plate, saving the tedious cleaning work. Attached Figure Description

[0042] Please refer to this carefully. Figure 1 , 2 Method 3, the method for removing impurities from high-purity quartz sand at high temperature, specifically includes the following steps:

[0043] Step 1: When using the device, first ensure the integrity of each component, and then support the device with the support legs 104.

[0044] Step 2: Start the device, open the solenoid valve 102, and feed the quartz sand into the device through the feed port 103;

[0045] Step 3: Simultaneously, the flame-spraying device 201 is activated, and the quartz sand falls into the combustion chamber 205. The impurities inside the quartz sand are heated and burned by the flames sprayed from the flame-spraying device 201, and the two sets of fans 203 are powered on and started to generate wind, which is blown into the device through the two sets of impurity outlets 202, blowing the cleaned and filtered quartz sand to the middle position of the filter plate 301.

[0048] Step Six: The solidified impurity blocks are then dislodged by the vibration of the fixing frame 303 and fall into the two sets of impurity outlets 202.

When the waste collection boxes 204 are full, they are lifted by the handle 207 and the waste is processed to complete the impurity removal work of the quartz sand.

[0049] The working principle of this invention is as follows: First, ensure the integrity of all components of the device. Then, support the device using the support legs 104. Start the device, open the solenoid valve 102, and feed quartz sand into the device through the feed inlet 103. Simultaneously, the flame-spraying device 201 is activated, and the quartz sand falls into the combustion chamber 205. Impurities inside the quartz sand are heated and burned by the flames emitted from the flame-spraying device 201, causing them to clump together. Meanwhile, two sets of fans 203 are energized and activated, generating airflow. The impurities are then discharged through two sets of exhaust fans. Inlet 202 blows cleaned and filtered quartz sand into the device, pushing it to the center of filter plate 301. The cleaned quartz sand falls onto the surface of filter plate 301. Simultaneously, four sets of vibration devices 304 are energized and start vibrating, and the fixing frame 303 also vibrates. Through spring 306 and telescopic rod 305, the vibration amplitude of the fixing frame 303 is increased to filter and remove impurities from the quartz sand more quickly. The sealing ring 307 on the outside of the fixing frame 303 is located within the sliding groove 308. The device slides to prevent other impurities from entering the funnel 302. The filtered and impurity-removed quartz sand falls into the funnel 302 and is discharged through the outlet 105 at the bottom of the funnel 302. The solidified impurity lumps are shaken by the fixed frame 303 and fall into the two sets of impurity outlets 202, and are collected in the two sets of waste collection boxes 204 at the bottom of the two sets of impurity outlets 202. When the waste collection box 204 is full, it is lifted by the handle 207 and the waste is processed to complete the impurity removal work of the quartz sand. This device is convenient to use and simple to operate. Through the impurity removal component 2, other impurities in the quartz sand can be removed by high temperature. At the same time, the air force of the blower 203 makes the heating more uniform and the impurity removal more thorough. Through the filter component 3, the fine impurity lumps inside the quartz sand after impurity removal can be filtered and removed. At the same time, the vibration reduces the accumulation and clogging of quartz sand on the surface of the filter plate 301, saving the tedious cleaning work.
