Description

Technical Field

[0001] This utility model relates to the technical field of quartz processing, and in particular to a quartz raw material impurity screening device. Background Technology

[0002] In the quartz processing industry, the quality of raw quartz plays a crucial role in subsequent processing techniques and the performance of the final product. During mining, transportation, and initial processing, raw quartz often becomes contaminated with various impurities, including but not limited to soil, sand, light dust, and moisture adsorbed from environmental factors. The presence of these impurities can have numerous adverse effects on quartz processing.

[0003] For example, in the melting process of quartz products, if the impurity content in the raw materials is too high, it can lead to problems such as uneven melt distribution and bubble formation, thereby affecting key performance indicators of the quartz products, such as transparency, strength, and thermal stability. In the quartz crystal growth process, the introduction of impurities may interfere with the normal growth of the crystal, causing crystal defects and reducing the quality and application value of the crystal.

[0004] Traditional methods for screening impurities in quartz raw materials have several limitations. Existing screening devices only screen based on particle size, and cannot effectively remove some lightweight impurities attached to the surface of quartz particles or impurities that are stuck together due to moisture. As a result, the purity of the quartz raw material after screening is still insufficient to meet the requirements of high-precision processing. Utility Model Content

[0005] This utility model aims to at least partially solve one of the technical problems in the related art.

[0006] Therefore, the purpose of this utility model is to propose a quartz raw material impurity screening device, which removes some impurities from the quartz raw material before it enters the sieve for screening, significantly improving the purity of the raw material and helping to obtain higher quality quartz products in subsequent processing stages.

[0007] To achieve the above objectives, this utility model proposes a quartz raw material impurity screening device, comprising: a sieve box, the sieve box having at least two discharge ports, and multiple layers of sieve mesh arranged vertically at intervals inside the sieve box, the sieve mesh aperture of each layer of sieve mesh decreasing sequentially from top to bottom, and each layer of sieve mesh being inclinedly arranged inside the sieve box.

[0008] A support frame, comprising a screen box frame and a feeding frame;

[0009] The vibration generating mechanism includes a vibration motor and a mechanical spring. The screen box is connected to the support frame via the mechanical spring, and the vibration motor is connected to the bottom wall of the screen box.

[0010] The feeding device includes a feeding hopper, which is disposed on the top of the screen box and supported by a feeding frame. The feeding hopper is shaped to be larger at the top and smaller at the bottom.

[0011] A blower device includes a blower head and an air compressor. The blower head has a hollow internal structure, and its surface has multiple sets of blow holes that communicate with the interior. The blow holes are oriented towards the discharge direction of the feed hopper. The output end of the air compressor is connected to the interior of the blower head.

[0012] This utility model's quartz raw material impurity screening device removes some impurities from the quartz raw material before it enters the sieve, significantly improving the purity of the raw material. This helps to obtain higher quality quartz products in subsequent processing stages. The blown airflow not only carries away light impurities but also removes moisture from the raw material during its action. Moisture removal effectively prevents the quartz raw material and impurities from sticking together due to moisture, making it easier to separate the quartz raw material and impurities during the subsequent vibrating screening stage, further improving the overall impurity removal efficiency.

[0013] In addition, the quartz raw material impurity screening device proposed in the application may also have the following additional technical features:

[0014] Specifically, the feeding device further includes a feeding conveyor belt, the discharge port of which is located above the feeding hopper, and the feeding conveyor belt is supported by a feeding frame.

[0015] Specifically, the blower head is rotatably connected to the support frame via a damping shaft, and one end of the blower head is connected to a rotating head.

[0016] Specifically, the discharge port of the feed hopper is fixed with an inclined elastic plate.

[0017] Specifically, it also includes a debris collection bag, which is disposed on one side of the support frame.

[0018] Specifically, a heating frame is fixed to the blowing surface of the blowing head, and a heating wire is provided inside the heating frame.

[0019] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0027] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0028] The quartz raw material impurity screening device of this utility model embodiment will be described below with reference to the accompanying drawings.

[0029] like Figures 1-4 As shown, the quartz raw material impurity screening device of this utility model embodiment may include: a screen box 1, the screen box 1 is provided with at least two discharge ports 101, and multiple layers of screens 102 are arranged vertically inside the screen box 1, the screen hole diameter of each layer of screens 102 decreases from top to bottom, and each layer of screens 102 is inclined inside the screen box 1.

[0030] Support frame 2, which includes screen box frame 201 and feed frame 202.

[0031] The vibration generating mechanism 3 includes a vibration motor 301 and a mechanical spring 302. The screen box 1 is connected to the support frame 2 through the mechanical spring 302, and the vibration motor 301 is connected to the bottom wall of the screen box 1.

[0032] The feeding device 4 includes a feeding hopper 401, which is located on the top of the screen box 1. The feeding hopper 401 is supported by the feeding frame 202 and has a shape that is larger at the top and smaller at the bottom.

[0033] The blowing device 5 includes a blowing head 501 and an air compressor 502. The blowing head 501 has a hollow structure inside. Multiple sets of blowing holes communicating with the inside are opened on the surface of the blowing head 501. The blowing holes are oriented towards the discharge direction of the feed hopper 401. The output end of the air compressor 502 is connected to the inside of the blowing head 501.

[0034] In one embodiment of this utility model, such as Figure 1 and Figure 4 As shown, during the process of the quartz raw material entering the screen box 1 from the feed hopper 401, the air compressor 502 of the blowing device 5 is driven. The air compressor 502 sends compressed gas to the blowing head 501. The airflow is sprayed out from the blowing port of the blowing head 501. The blown airflow sprays the falling quartz raw material, spraying the light impurities in the quartz raw material away from the screen box 1. Then the impurities enter the screen box 1. The vibration motor 301 of the vibration generating mechanism 3 drives the quartz raw material to jump and roll continuously on the screen 102, making full contact with the screen 102, so that the quartz raw material and impurities are separated. During the process of the airflow blowing towards the quartz raw material, the airflow can also carry away the moisture in the quartz raw material, which can reduce the adhesion between the quartz raw material and impurities.

[0035] In one embodiment of this utility model, such as Figure 1 As shown, the feeding device 4 also includes a feeding conveyor belt 402. The discharge port of the feeding conveyor belt 402 is located above the feeding hopper 401. The feeding conveyor belt 402 is supported by the feeding frame 202. The feeding conveyor belt 402 has an inclined conveyor belt and a flat conveyor belt. The conveyor belt is driven by a motor-driven shaft, which drives the roller to move the conveyor belt. It is best to install a baffle on the inclined conveyor belt to facilitate the upward movement of the quartz raw material. The feeding conveyor belt 402 lifts the quartz raw material and lowers it through the feeding hopper 401.

[0036] Another possibility is that the feeding conveyor belt 402 is a mesh conveyor belt, and fans can be installed above and below the conveyor belt to dry the quartz raw material.

[0037] In one embodiment of this utility model, such as Figure 1 and Figure 4As shown, the blower head 501 is rotatably connected to the support frame 2 via a damping shaft, and a rotating head is connected to one end of the blower head 501. The blower head 501 can be adjusted in angle to change the airflow direction.

[0038] In one embodiment of this utility model, such as Figure 5 As shown, the outlet of the feed hopper 401 is fixed with an inclined elastic plate 6. During the falling process of the quartz raw material, the raw material, impurities and elastic plate 6 come into contact, causing it to bounce up, the raw material to disperse, and the airflow to blow out the impurities more easily.

[0039] In one embodiment of this utility model, such as Figure 2 As shown, it also includes a debris collection bag 7, which is disposed on one side of the support frame 2 and is used to collect impurities blown out by the airflow.

[0040] In one embodiment of this utility model, such as Figure 1 and Figure 4 As shown, a heating frame 8 is fixed to the blowing surface of the blowing head 501. A heating wire is installed inside the heating frame 8. The heating wire heats up when energized. When the airflow passes through the heating wire, it can carry away the moisture of the raw material, preventing the raw material from sticking together and making it difficult to separate the raw material and impurities.

[0041] Specifically, the air compressor 502 delivers compressed gas to the blower head 501. The airflow is ejected from the nozzle of the blower head 501 and blown onto the falling quartz raw material, spraying the light impurities in the quartz raw material away from the screen box 1. Then the impurities enter the interior of the screen box 1, separating the quartz raw material from the impurities. During the process of the airflow blowing onto the quartz raw material, the airflow can also carry away the moisture in the quartz raw material, which can reduce the adhesion between the quartz raw material and the impurities.

[0042] In summary, the quartz raw material impurity screening device of this utility model removes some impurities from the quartz raw material before it enters the sieve 102 for screening, significantly improving the purity of the raw material. This helps to obtain higher quality quartz products in subsequent processing stages. The blown airflow not only carries away light impurities but also removes moisture from the raw material during the airflow process. The removal of moisture effectively prevents the quartz raw material and impurities from sticking together due to moisture, making it easier to separate the quartz raw material and impurities in the subsequent vibrating screening stage, further improving the overall impurity removal efficiency.
