Description

Technical Field

[0001] This utility model relates to the field of quartz sand screening technology, specifically to a screening device for quartz sand. Background Technology

[0002] Quartz sand is quartz particles produced by crushing and processing quartz stone. Quartz stone is a non-metallic mineral, a hard, wear-resistant, and chemically stable silicate mineral. Quartz sand is milky white or colorless and translucent, with a Mohs hardness of 7. It is an important industrial mineral raw material, a non-hazardous chemical, and widely used in industries such as glass, casting, ceramics, fireproofing materials, and ferrosilicon smelting. During the production and processing of quartz sand, screening is necessary.

[0003] In most existing methods of quartz sand screening, the quartz sand is poured into a screening machine, and then the machine is driven by a drive mechanism to rotate and screen the quartz sand.

[0004] Although the above equipment can screen quartz sand, the screen plate holes on the screening machine are fixed in size. Therefore, when different mesh sizes of quartz sand need to be screened, the screen plate needs to be removed from the screening machine and then reinstalled to screen different sizes of quartz sand. However, since personnel need to constantly disassemble and reassemble, it increases the workload of personnel and indirectly reduces the screening efficiency. Utility Model Content

[0005] In view of this, the present invention provides a screening device for quartz sand. The present invention can change the size of the screening holes, thereby realizing the screening of quartz sand of different particle sizes, and at the same time preventing quartz sand from clogging.

[0006] To solve the above-mentioned technical problems, this utility model provides a screening device for quartz sand, including a screening cylinder, a circular screen one disposed at the bottom of the screening cylinder, a circular cylinder rotatably disposed inside the screening cylinder, a circular screen two disposed at the bottom of the circular cylinder, the circular screen one and the circular screen two being in contact, anti-clogging components disposed on the circular screen one and the circular screen two, the anti-clogging components including an anti-clogging plate rotatably disposed on the upper surface of the circular screen two, and a rotation drive component disposed at the top of the screening cylinder and the top of the circular cylinder, the rotation drive component being used to rotate the inside of the circular cylinder; that is, when the rotation drive component is activated... At this time, the circular cylinder rotates inside the screening cylinder, and then the second circular screen rotates and contacts the first circular screen, indirectly causing the holes on the first and second circular screens to misalign, thereby changing the size of the screening holes and achieving screening of different particle sizes of quartz sand. Then, the anti-blocking plate in the anti-blocking component rotates inside the second circular screen, which can make the anti-blocking plate contact the quartz sand on the screen and push the quartz sand forward, helping to break the static accumulation state of the quartz sand on the screen, making it looser and easier to pass through the screen holes, thereby preventing clogging.

[0007] The rotary drive assembly also includes a circular shell disposed on the top of the screening cylinder, a gear installed inside the circular shell, and a toothed ring disposed on the top of the circular cylinder, the toothed ring being located inside the circular shell and meshing with the gear; that is, the gear provides transmission to the toothed ring, thereby providing rotation to the circular cylinder.

[0008] The rotary drive assembly also includes a fixed column that runs through the inside of the circular shell and passes through the inside of the gear. A drive button is provided at the bottom of the circular cylinder and is fixed to one end of the fixed column. The drive button provides convenience for personnel to operate.

[0009] The anti-clogging component also includes a conical block set on the circular screen, with a rotating column rotatably arranged inside the conical block. The two ends of the outer surface of the rotating column are fixed to one side of the anti-clogging plate; that is, the anti-clogging plate is installed on the rotating column, thereby providing support for the anti-clogging plate.

[0010] The anti-clogging component also includes a motor installed at the bottom of the circular screen, with the motor's output shaft fixedly connected to one end of the rotating column; that is, the motor provides drive for the rotating column.

[0011] The bottom of the screening cylinder is equipped with a base, which provides support for the screening cylinder.

[0012] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0013] 1. The quartz sand screening is achieved by installing a rotating column inside a conical block. Simultaneously, a motor provides drive to the rotating column, causing it to rotate and drive the anti-clogging plate. This pushes the quartz sand on the second circular screen, preventing the quartz sand from remaining stationary on the second circular screen and thus avoiding clogging.

[0014] 2. The quartz sand is screened by gears installed inside a circular shell. When a person rotates a knob, the gears indirectly provide transmission to the toothed ring on the outer arc surface of the circular cylinder, which in turn drives the circular cylinder to rotate. This causes the second circular screen to rotate on the first circular screen, thereby changing the size of the screening holes and achieving the screening of quartz sand of different particle sizes, while improving screening efficiency.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-4 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0024] like Figure 1-4 As shown: This embodiment provides a screening device for quartz sand, including a screening cylinder 100. A circular screen 103 is installed at the bottom of the screening cylinder 100 and is fixed to the bottom of the screening cylinder 100 by welding. A circular cylinder 102 is rotatably installed inside the screening cylinder 100, and a circular screen 104 is installed at the bottom of the circular cylinder 102. The circular screen 103 and the circular screen 104 are in contact. The outer surface of the circular cylinder 102 is mounted inside the screening cylinder 100 by bearings. Because the circular cylinder 102 can rotate freely inside the screening cylinder 100, the holes on the circular screen 103 and the circular screen 104 will be misaligned, thereby changing the size of the screening holes and realizing the screening of quartz sand of different particle sizes. Anti-clogging components 300 are provided on the shaped screen 103 and the circular screen 104. The anti-clogging component 300 includes an anti-clogging plate 304 rotatably disposed on the upper surface of the circular screen 104. As the anti-clogging plate 304 rotates on the circular screen 104, it comes into contact with the quartz sand on the screen and pushes the quartz sand forward, which helps to break the static accumulation state of the quartz sand on the screen, making it looser and easier to pass through the screen holes, effectively preventing the accumulation and clogging of quartz sand on the screen. Rotary drive components 200 are provided on the top of the screening cylinder 100 and the top of the circular cylinder 102. The rotary drive components 200 are used to rotate the inside of the circular cylinder 102, so that personnel can drive the circular cylinder 102 inside the screening cylinder 100.

[0025] First, the rotary drive assembly 200 drives the cylindrical cylinder 102 to rotate freely within the screening cylinder 100. The holes on the first circular screen 103 and the second circular screen 104 become misaligned, thereby changing the size of the screening holes and achieving screening of quartz sand of different particle sizes. Then, quartz sand is added into the cylindrical cylinder 102, and the anti-blocking plate 304 in the anti-blocking assembly 300 rotates within the holes on the second circular screen 104. This causes the anti-blocking plate 304 to contact the quartz sand on the screen and push the quartz sand forward, helping to break the static accumulation of quartz sand on the screen, making it looser and easier to pass through the screen holes, effectively preventing the accumulation and clogging of quartz sand on the screen.

[0026] Rotary drive assembly 200, such as Figure 2 As shown,

[0027] The rotary drive assembly 200 also includes a circular shell 201 disposed on the top of the screening cylinder 100. The circular shell 201 is fixedly installed on the top of the screening cylinder 100 by welding. A gear 204 is installed inside the circular shell 201. A toothed ring 205 is disposed on the top of the circular cylinder 102. The toothed ring 205 is fixedly installed on the outer surface of the circular cylinder 102 by welding. The toothed ring 205 is located inside the circular shell 201. The toothed ring 205 is meshed with the gear 204. When the gear 204 rotates, the gear 204 provides transmission for the toothed ring 205.

[0028] The rotary drive assembly 200 also includes a fixing post 203 that passes through the circular shell 201 and is inserted into the gear 204. A drive button 202 is provided at the bottom of the circular cylinder 102 and is fixedly disposed at one end of the fixing post 203.

[0029] First, the drive button 202 is rotated, which in turn drives the fixed column 203 to rotate, thereby causing the gear 204 to rotate. Indirectly, the gear 204 provides a transmission function for the gear ring 205, so that the circular cylinder 102 rotates inside the screening cylinder 100, which facilitates the adjustment of the misalignment size of the holes in the circular screen 104 on the circular screen 103.

[0030] Anti-blocking component 300 Figure 4 As shown,

[0031] The anti-blocking component 300 also includes a conical block 302 disposed on the circular screen 104. The conical block 302 is fixed to the circular screen 104 by welding. A rotating column 303 is rotatably disposed inside the conical block 302. The two ends of the outer surface of the rotating column 303 are fixed to one side of the anti-blocking plate 304. The rotating column 303 can drive the anti-blocking plate 304 to rotate, and the rotating column 303 rotates accordingly.

[0032] The anti-clogging component 300 also includes a motor 301 disposed at the bottom of the circular screen 103, and the output shaft of the motor 301 is fixedly disposed at one end of the rotating column 303;

[0033] When the motor 301 starts, the output shaft of the motor 301 can drive the rotating column 303 to rotate, thereby causing the rotating column 303 to drive the anti-blocking plate 304 to rotate. During the rotation, the anti-blocking plate 304 will continuously push the quartz sand particles to prevent them from accumulating on the screen.

[0034] 100 sieve cylinder Figure 1 As shown,

[0035] A base 101 is provided at the bottom of the screening cylinder 100, which provides support for the screening cylinder 100;

[0036] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.
