Description

Technical Field

[0001] This utility model relates to the technical field of quartz sand production equipment, specifically a purification device for the production of high-purity quartz sand. Background Technology

[0002] Quartz sand is a granular material obtained by crushing and processing quartz stone, and its main component is silicon dioxide (SiO2). Quartz sand is widely found in nature and is an important industrial mineral raw material. Due to its high hardness, strong wear resistance, and stable chemical properties, quartz sand is widely used in glass manufacturing, casting, ceramics, refractory materials, ferrosilicon smelting, construction, chemical industry, and many other fields.

[0003] Quartz sand raw materials usually contain a lot of impurities, which typically include iron-containing minerals such as magnetite and hematite. Their presence affects the purity and quality of quartz sand, and magnetic separation is required when producing high-purity quartz sand.

[0004] While magnetic separation can remove most magnetic impurities, it may leave non-magnetic or weakly magnetic impurities and cannot classify the particle size of quartz sand. This results in residual impurities and uneven particle size distribution in the quartz sand, affecting its quality and application areas. Furthermore, existing magnetic separation devices lack washing and screening steps, potentially requiring additional processing steps to achieve the required purity and particle size. This not only increases processing time but may also raise costs and reduce overall processing efficiency. Therefore, this paper proposes a purification device for high-purity quartz sand production to address these issues. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a purification device for the production of high-purity quartz sand. It has the advantages of simultaneously screening and washing quartz sand during magnetic separation, thus solving the problem of poor adaptability of existing magnetic separation equipment during use.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a purification device for the production of high-purity quartz sand, comprising a mounting frame for installation, a mounting hopper for installation on the mounting frame, a magnetic separator for magnetic separation at the bottom of the mounting hopper, a screening wheel for preliminary screening of quartz sand raw material inside the mounting hopper, a linkage shaft for connection on the screening wheel, both ends of the linkage shaft being rotatably connected to the mounting frame and one end of the linkage shaft being connected to a transmission component for transmission, the transmission component being installed on the mounting hopper;

[0007] Above the screening wheel is a washing component for washing the quartz sand raw material, and at the bottom of the installation hopper is a fine screening component for screening the quartz sand. The fine screening component is equipped with a transmission component for transmission.

[0008] Furthermore, the screening wheel is composed of multiple bucket-shaped screen frames forming a ring, with the feed inlet on the side of the screen frame facing the center, and multiple screen holes provided on the outer side.

[0009] Furthermore, the inner side of the screening wheel is provided with a first screening frame and a second screening frame for preliminary screening of the quartz sand raw material, and different types of screens are provided in the first screening frame and the second screening frame.

[0010] Furthermore, the fine screening component includes a feeding hopper installed at the bottom of the installation hopper, a discharge port at the bottom of the feeding hopper, an elastic sealing cover for sealing on one side of the discharge port, and a fine screening frame for fine screening of quartz sand on the elastic sealing cover.

[0011] Furthermore, the transmission assembly includes a mounting frame for installation and a transmission motor for output. The output end of the transmission motor is connected to a transmission belt, the transmission belt is connected to a transmission shaft, the transmission shaft is rotatably connected inside the transmission motor, the transmission shaft is connected to a linkage component, the linkage component is connected to a linkage rod, and the other end of the linkage rod extends to the outside of the mounting frame and is connected to the elastic sealing cover.

[0012] Furthermore, the linkage consists of a connecting shaft and a transmission cam, with the transmission cam used to control the linkage rod to reciprocate.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1:

[0023] Please see Figure 1-4This embodiment of a purification device for producing high-purity quartz sand includes a mounting frame 1 for installation, a mounting hopper 11 for installation on the mounting frame 1, a magnetic separator 18 for magnetic separation at the bottom of the mounting hopper 11, a screening wheel 14 for preliminary screening of quartz sand raw material inside the mounting hopper 11, a linkage shaft 15 for connection on the screening wheel 14, both ends of the linkage shaft 15 being rotatably connected to the mounting frame 1 and one end of the linkage shaft 15 being connected to a transmission component 16 for transmission, the transmission component 16 being installed on the mounting hopper 11; a rinsing component 17 for rinsing the quartz sand raw material is also provided above the screening wheel 14, and a fine screening component 2 for screening quartz sand is provided at the bottom of the mounting hopper 11, the fine screening component 2 being provided with a transmission component 3 for transmission. In practical use, when screening quartz sand raw materials is required, the quartz sand raw materials are first placed in the screening wheel 14. Then, the operator can control the transmission component 16 to drive the linkage shaft 15, causing the screening wheel 14 to rotate. During the rotation of the screening wheel 14, the quartz sand raw materials at the bottom will be screened under the action of gravity. The screened quartz sand raw materials will achieve a good adsorption effect on iron-containing minerals such as magnetite and hematite under the action of the magnetic separator 18, thereby achieving the effect of magnetic separation. At the same time, during the rotation of the screening wheel 14, the operator can control the flushing component 17 to flush the quartz sand raw materials in the screening wheel 14, thereby further washing away the impurities in the quartz sand raw materials, effectively increasing the screening and impurity removal effect of the device during use.

[0024] In this embodiment, a preferred technical solution is provided: the screening wheel 14 is composed of multiple bucket-shaped screen frames forming a ring, with the feed inlet on the side of the screen frame facing the center, and multiple screen holes on the outer side. The inner side of the screening wheel 14 is provided with a first screening frame 12 and a second screening frame 13 for preliminary screening of the quartz sand raw material. Different types of screens are installed in both the first screening frame 12 and the second screening frame 13. It is worth noting that both the first screening frame 12 and the second screening frame 13 are mounted on the mounting hopper 11. This design enables it to achieve good multi-stage screening during use. When the operator controls the rotation of the screening wheel 14, and the remaining material after screening is located above the screening wheel 14, the remaining material after screening will be screened again by gravity through the first screening frame 12 or the second screening frame 13. The operator can control the quartz sand material to be screened through the first screening frame 12 or the second screening frame 13 by controlling the forward and reverse rotation of the screening wheel 14, further increasing the screening effect of the device during use and avoiding incomplete screening and material waste.

[0025] It is worth noting that in this embodiment, the outlets at the bottom of the second screening frame 13 and the first screening frame 12 are both inclined to the outside of the screening wheel 14 and located inside the hopper 21, thereby ensuring the smooth discharge of the screened raw materials.

[0026] As a preferred technical solution in this embodiment: the fine screening component 2 includes a feeding hopper 21 installed at the bottom of the mounting hopper 11. A discharge port 22 is provided at the bottom of the feeding hopper 21, and an elastic sealing cover 23 for sealing is provided on one side of the discharge port 22. A fine screening frame 24 for finely screening the quartz sand is provided on the elastic sealing cover 23. The quartz sand, after being screened by the first screening frame 12 and the second screening frame 13, would normally fall onto the fine screening frame 24 inside the feeding hopper 21 under gravity. The fine screening frame 24 further enhances the screening effect on the quartz sand raw material during use.

[0027] As a preferred technical solution in this embodiment: the transmission assembly 3 includes a mounting frame 32 for installation and a transmission motor 31 for output. The output end of the transmission motor 31 is connected to a transmission belt 33, and the transmission belt 33 is connected to a transmission shaft 34. The transmission shaft 34 is rotatably connected inside the transmission motor 31. The transmission shaft 34 is connected to a linkage 35, and the linkage 35 is connected to a linkage rod 36. The other end of the linkage rod 36 extends to the outside of the mounting frame 32 and is connected to the elastic sealing cover 23. By setting the transmission assembly 3 and connecting it to the fine screening frame 24, the screening effect of the fine screening frame 24 can be effectively increased. Specifically, the operator can control the transmission motor 31 to drive the transmission shaft 34 to rotate. During the rotation of the transmission shaft 34, the linkage 35 can be driven to rotate. During the rotation of the linkage 35, the linkage rod 36 can be driven to reciprocate, thereby driving the fine screening frame 24 to reciprocate, thus accelerating the screening effect of the fine screening frame 24 on the quartz sand raw material.

[0028] As a preferred technical solution in this embodiment, the linkage 35 consists of a connecting shaft and a transmission cam, which controls the reciprocating motion of the linkage rod 36. This arrangement effectively ensures the transmission effect during use.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
