Description

Technical Field

[0001] This utility model relates to the technical field of quartz sand grading equipment, and in particular to an automatic impurity removal and refining quartz sand grading equipment. Background Technology

[0002] In the production and preparation of quartz sand, multiple grading processes are generally required to obtain quartz sand products of the corresponding particle size.

[0003] In existing technologies, when classifying quartz sand, a screen is usually placed on an inclined frame, and vibration is used to move the quartz sand. Quartz sand of the correct size will fall through the screen into the collection hopper below. However, in order to ensure the continuity of screening, the quartz sand will continue to move. When it reaches the end point, some quartz sand of the correct size will still fall along with larger quartz sand. There is room for improvement in screening quality. In view of this, we propose an automatic impurity removal and refining quartz sand classification device. Utility Model Content

Detailed Implementation

[0024] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0025] Please see Figure 1-6 This utility model provides a technical solution: an automatic impurity removal and refining quartz sand grading device, including a base 1, two mounting plates 2 fixedly connected to the upper surface of the base 1, a screening cylinder 3 rotatably connected between the two mounting plates 2, two arc-shaped baffles 4 fixedly connected between the two mounting plates 2, and conical collecting hoppers 5 fixedly connected to the lower surface of each of the two arc-shaped baffles 4. A feed inlet 6 is provided on the surface of the screening cylinder 3, and a first screening hole 7 and a second screening hole 8 are provided on the screening cylinder 3. The diameter of the second screening hole 8 is larger than that of the first screening hole 7. A first screening hole 7 and a second screening hole 8 are distributed on both sides of the screening cylinder 3. The first screening hole 7 is distributed on the lower side of the screening cylinder 3. A connecting shaft 9 is fixedly connected to the right side surface of the screening cylinder 3. The right end of the connecting shaft 9 rotates through the right side surface of the right mounting plate 2. A screening drive assembly is provided on the base 1. By utilizing the circular design of the screening cylinder 3, small particles of quartz sand can be completely screened out first when screening quartz sand, without worrying about the problem that small particles cannot be completely screened due to a large amount of quartz sand or a short stroke.

[0026] Furthermore, the screening drive assembly includes a motor mounting bracket 10, on which a forward and reverse motor 11 is fixedly connected. The output end of the forward and reverse motor 11 is fixedly connected to a rotating shaft 12 via a coupling. Synchronous pulleys 13 are fitted onto the outer surfaces of both the rotating shaft 12 and the connecting shaft 9. A synchronous belt 14 meshes between the two synchronous pulleys 13. A slide rail 15 is fixedly connected to the upper surface of the base 1. A collection frame 16 is provided on the base 1, and the collection frame 16 is slidably connected to the slide rail 15. Electric push rods 17 are fixedly connected to the adjacent surfaces of the two mounting plates 2. The output end of the electric push rod 17 is fixedly connected to the collection frame 16. A magnetic rod 18 is provided on the right surface of the right mounting plate 2. The left end of the rod 18 slides through the left side surface of the conical collecting hopper 5. A sealing door 19 is slidably connected to the inner wall of the feed inlet 6. A connecting sleeve 20 is fixedly connected to the sealing door 19. A first telescopic cylinder 21 is fixedly connected to the inner wall of the feed inlet 6. A second telescopic cylinder 22 is slidably connected to the inner wall of the first telescopic cylinder 21. A locking post 23 is fixedly connected to the left end of the second telescopic cylinder 22. The locking post 23 is compatible with the connecting sleeve 20. A spring 24 is fixedly connected between the inner wall of the first telescopic cylinder 21 and the right end of the second telescopic cylinder 22. The magnetic rod 18 can automatically adsorb metal particles when the quartz sand falls, thereby avoiding impurities inside the quartz sand after screening and improving the quality of the screened product.

[0027] Among them, the forward and reverse motor 11 is also equipped with a power supply, wires, controller and microcomputer, etc., which are not the main structures and will not be described in detail.

[0028] Working principle: When classifying quartz sand, firstly, the second telescopic cylinder 22 is pulled, which causes the locking pin 23 to separate from the connecting sleeve 20. As the second telescopic cylinder 22 moves, it synchronously compresses the spring 24. Then, the closing door 19 is opened, allowing the quartz sand to be fed into the screening cylinder 3. Subsequently, the reciprocating rotation of the forward and reverse motor 11, in conjunction with the rotating shaft 12, drives the synchronous wheel 13 to rotate. The two synchronous wheels 13, in conjunction with the synchronous belt 14, drive the connecting shaft 9 to rotate, which in turn drives the screening cylinder 3 to reciprocate. This reciprocating rotation of the screening cylinder 3 causes the internal quartz sand to roll. The movement allows quartz sand smaller than the first screening hole 7 to enter the collection frame 16 through the conical collection hopper 5. As the quartz sand passes through the conical collection hopper 5, the magnetic rod 18 adsorbs the metal particles. After the small particles are screened, the electric push rod 17 drives the collection frame 16 to move horizontally, so that the other collection frame 16 is aligned with the conical collection hopper 5. At this time, the forward and reverse motor 11 drives the screening cylinder 3 to rotate at a large angle, so that the quartz sand can contact the second screening hole 8, and thus the internal quartz sand can enter the collection frame 16 through the second screening hole 8.

[0029] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
