Description

Technical Field

[0001] This utility model relates to the technical field of quartz sand grading, and in particular to a quartz sand screening device. Background Technology

[0002] Quartz sand is a product that can be used in many different downstream applications, including casting, construction, and glass production. The required particle size of quartz sand varies in different industries and downstream products. Therefore, the particle size will be adjusted during the quartz sand screening process.

[0003] In existing technologies, multi-stage linear vibrating screens and multi-stage disc screens are commonly used to achieve multi-stage screening of quartz sand. However, sometimes there are situations where only one or two particle size requirements are needed for a long time, rather than production with multiple grading requirements at the same time. The above-mentioned equipment has a relatively complex structure, and many of its grading components may be idle. Therefore, single-stage screening equipment may be used for screening. However, the structure of such equipment is also relatively complex, and the time required to change the screening grade is also long. Utility Model Content

[0004] To address the aforementioned shortcomings, this utility model provides a quartz sand screening device that allows for easy replacement of the cylindrical screen plate, enabling the screening of quartz sand to a specified particle size.

[0005] In order to achieve the purpose of this utility model, the following technology is proposed to be adopted: A quartz sand screening device, comprising: The mounting ring includes an inclined ring body with a ring groove on the outer periphery of the ring body, a toothed ring fixed at the upper inclined end of the ring body, and an outer ring at the lower inclined end of the ring body. The screening assembly is installed at the lower end of the mounting ring and includes an inner ring assembled on the inner circumference of the outer ring. The inner ring extends partially to the lower end of the outer ring and is provided with a cylindrical screen plate. The drive support unit is located at the lower end of the mounting ring and includes a rotary motor that is inclined and whose output shaft is parallel to the axis of the ring body. The output end of the rotary motor is provided with a gear that meshes with the gear ring, and a guide ring that slides into the ring groove is provided on one side of the rotary motor.

[0006] Furthermore, the outer ring has multiple through holes arranged in a circumferential array, and the inner ring has multiple screw holes arranged in a circumferential array that match the through holes. By screwing the through holes and the corresponding screw holes together, the screening component is fixedly installed on the mounting ring.

[0007] Furthermore, multiple first lifting rings are arranged in a circular array on the outer periphery of the inner ring.

[0008] Furthermore, multiple second lifting rings are arranged in a circumferential array on the outer periphery of the lower inclined end of the cylindrical screen plate.

[0009] Furthermore, a convex ring is fixed to the outer periphery of the lower inclined end of the cylindrical sieve plate, and each second lifting ring is located on the outer periphery of the convex ring.

[0010] Furthermore, the drive support unit also includes a first bracket and a second bracket, with a rotary motor located at the upper end of the first bracket and a guide ring fixed at the upper end of the second bracket.

[0011] The beneficial effects of this technical solution are as follows: 1. After preparing cylindrical screen plates with different particle size openings in advance, a screening component to be used can be installed on the mounting ring. The device structure of this application is simple and easy to replace quickly.

[0012] 2. This device is a single-stage screening device, which is convenient to operate and feed. Attached Figure Description

[0017] The technical solution of this application will be further described in detail below with reference to the accompanying drawings.

[0018] like Figures 1-4 The quartz sand screening device shown includes a mounting ring 1, a screening component 2, and a drive support unit 3.

[0019] The mounting ring 1 includes an inclined ring body 11, an annular groove 12 is provided on the outer periphery of the ring body 11, a toothed ring 13 is fixed at the upper inclined end of the ring body 11, and an outer ring 14 is provided at the lower inclined end of the ring body 11. Multiple through holes 15 are provided in a circular array on the periphery of the outer ring 14.

[0020] The screening assembly 2 is installed at the lower end of the mounting ring 1, including an inner ring 21 fitted to the inner circumference of the outer ring 14. The outer circumference of the inner ring 21 has a plurality of screw holes 22 arranged in a circular array, each matching a through hole 15. By screwing the through holes 15 and the corresponding screw holes 22, the screening assembly 2 is fixedly installed on the mounting ring 1. A portion of the inner ring 21 extends downwards from the outer ring 14. The outer circumference of this extended portion of the inner ring 21 also has a plurality of first lifting rings 23 arranged in a circular array. A cylindrical screen plate 24 is provided at the lower end of the inner ring 21. A protruding ring 25 is fixed to the outer circumference of the lower end of the cylindrical screen plate 24. A plurality of second lifting rings 26 are arranged in a circular array on the outer circumference of the protruding ring 25. It should be noted that the screen holes of the cylindrical screen plate 24 shown in the attached drawings are only schematic. Since the screening is for quartz sand, the actual screen holes are very small. The attached drawings show larger screen holes for clearer illustration and to avoid blurring.

[0021] The drive support unit 3 is located at the lower end of the mounting ring 1 and the screening assembly 2, and includes a first bracket 31, a second bracket 34, and a pair of third brackets 36. The upper end of the first bracket 31 is provided with a rotary motor 32 that is inclined and whose output shaft is parallel to the axis of the ring body 11. The output end of the rotary motor 32 is provided with a gear 33 that meshes with the gear ring 13. The upper end of the second bracket 34 is fixed with a guide ring 35 that slides into the ring groove 12. One side of the upper end of the third bracket 36 is fixed with a rotating rod 37. One end of the rotating rod 37 is rotatably fitted with a support wheel 38. The periphery of the support wheel 38 abuts against the outer periphery of the lower inclined end of the cylindrical screen plate 24. Specifically, when actually processing the guide ring 35, it can be processed in two parts. For example, the lower half of the guide ring 35 can be fixed to the second bracket 34 first, and after the mounting ring 1 is clamped into the lower half of the guide ring 35, the upper half of the guide ring 35 can be welded and processed.

[0022] Work style: First, various screening components 2 are processed, and the cylindrical screen plates 24 of each screening component 2 have screen holes with different particle sizes. Then, the feeding and unloading equipment is set up. Specifically, for feeding, manual shoveling can be used, or an inclined conveyor belt can be set at the opening at the upper end of the mounting ring 1 for feeding. For unloading screened quartz sand, a receiving hopper can be set below the position where the screening component 2 is to be installed, or another conveyor belt can be set up for receiving. For unscreened quartz sand, the same collection equipment as described above can be set at the lower end outlet of the cylindrical screen plate 24 at the position where the screening component 2 is to be installed.

[0023] Next, the screening component 2 will be installed. A crane can be used to lift a first lifting ring 23 and a second lifting ring 26 for installation. Personnel can use a lifting platform or ladder to assist from a high position, so that the inner ring 21 is inserted into the outer ring 14 and the through holes 15 are aligned with the screw holes 22. Then, screws are used to fix the screening component 2, and at this time, the support wheel 38 is in contact with the cylindrical screen plate 24.

[0024] During screening, the rotary motor 32 drives the gear 33, which in turn drives the gear ring 13 and the entire mounting ring 1 to rotate. The screening assembly 2 rotates accordingly to perform screening. In order to avoid insufficient screening, the tilt angle of the mounting ring 1 should generally be small, usually not exceeding 15°.

[0025] The above are only some of the embodiments listed in this application and are not intended to limit this application.
