Description

Technical Field

[0001] This utility model relates to the field of high-purity quartz sand production technology, specifically a sand making machine for high-purity quartz sand production. Background Technology

[0002] The production of high-purity quartz sand includes crushing and screening, mineral processing and purification, fine processing and testing. The crushing process uses a crusher or sand making machine to crush the raw materials, and then uses nylon or stainless steel screens to classify them by particle size and remove oversized or undersized particles. Mineral processing and purification use magnetic separation to remove ferromagnetic impurities such as magnetite, hematite, and biotite, and flotation to separate aluminosilicate minerals such as feldspar and mica. An acid leaching process is also required to dissolve the metal ions on the surface and inside of the quartz. Finally, high-temperature treatment and hydrothermal treatment are used to expand the microcracks inside the quartz through thermal expansion and contraction, releasing the trapped impurities and removing organic matter.

[0003] Chinese Patent Publication No. CN111282673B discloses a high-purity quartz sand making machine, which uses a screen plate to screen crushed materials. Due to the lack of vibration or disturbance of the fixed screen, quartz sand particles are prone to forming an "arch bridge effect" due to mutual compression and friction, causing particles to get stuck in the screen holes. Moreover, relying on the natural fall or slow movement of the material, the amount of material passing through the screen per unit time is small. Therefore, a sand making machine for the production of high-purity quartz sand is proposed to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a sand making machine for the production of high-purity quartz sand. It has the advantages of multi-dimensional material disturbance to avoid clogging and smooth material flow. It solves the problems of fixed screens lacking vibration or disturbance, quartz sand particles easily forming an "arch bridge effect" due to mutual compression and friction, causing particles to get stuck in the screen holes, and relying on the natural fall or slow movement of materials, resulting in a small amount of material passing through the screen per unit time.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sand making machine for producing high-purity quartz sand, comprising a sand making machine and a feed hopper, wherein a screening chamber is provided at the bottom of the sand making machine, and a screening structure is provided inside the screening chamber;

[0006] The screening structure includes a screen slide, an elastic connector, a connector, a connecting cylinder, two bevel gears, an asynchronous motor, and a sliding component.

The connector is fixedly installed to the bottom of the elastic connector. The connecting cylinder is fixedly installed to the inner bottom wall of the screening chamber and connected to the connector. The asynchronous motor is fixed to the inner bottom wall of the screening chamber. The two bevel gears are respectively fixedly installed on the output shaft of the asynchronous motor and the outer surface of the connecting cylinder, and the outer surfaces of the two bevel gears mesh with each other. The sliding component is installed between the screen slide and the screening chamber.

[0007] Furthermore, the sliding component includes two support members and a connecting rod. The two support members are respectively fixedly installed on the screening chamber. Each of the two support members has a sliding groove inside. The connecting rod is fixedly connected to one end of the screen slide, and both ends of the connecting rod pass through the sliding groove and are slidably connected to the sliding groove.

[0008] Furthermore, the connecting sleeve includes an outer sleeve and an inner sleeve, which are fixedly connected, and a guide groove is provided on the inner sleeve.

[0009] Furthermore, the connector is an integral structure consisting of a support column and two bosses. One end of the support column extends into the interior of the inner sleeve, and the bosses extend into the interior of the guide groove. The bosses are slidably connected to the guide groove.

[0010] Furthermore, a limiting plate is fixedly installed on the inner bottom wall of the screening chamber to restrict the range of fine sand, and a guide plate for guiding fine sand is fixedly connected to the bottom of the screen slide. The screen slide and the inner bottom wall of the screening chamber form an angle of thirty degrees.

[0011] Furthermore, the sand making machine and the feed hopper are fixedly connected, the sand making machine is fixedly installed on the top of the screening chamber, and the sand making machine and the screening chamber are connected.

[0012] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0013] This sand making machine for producing high-purity quartz sand features a screening structure and uses an asynchronous motor with a bevel gear transmission to provide continuous and reliable power for the screening process, ensuring the stability of the screening operation. The guide groove of the connecting cylinder and the connecting boss precisely limit the movement trajectory of the screen slide, making it perform regular reciprocating motion, thereby improving screening accuracy and ensuring the accuracy of quartz sand particle size classification. It also provides additional disturbance to ensure smooth flow of coarse sand on the screen slide.

[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: Please refer to Figure 1-6 This embodiment of a sand making machine for producing high-purity quartz sand includes a sand making machine 1 and a feed hopper 2. A screening chamber 3 is provided at the bottom of the sand making machine 1. A screening structure is provided inside the screening chamber 3. The sand making machine 1 and the feed hopper 2 are fixedly connected. The sand making machine 1 is fixedly installed on the top of the screening chamber 3. The sand making machine 1 and the screening chamber 3 are connected.

[0023] Example 2: Please refer to Figure 1-6Based on Embodiment 1, the screening structure includes a screen slide 41, an elastic connector 42, a connector 43, a connecting cylinder 44, two bevel gears 45, an asynchronous motor 46, and a sliding component. The screen slide 41 is installed inside the screening chamber 3. The elastic connector 42 is hinged to the bottom of the screen slide 41. The connector 43 is fixedly installed to the bottom of the elastic connector 42. The connecting cylinder 44 is fixedly installed to the inner bottom wall of the screening chamber 3 and connected to the connector 43. The asynchronous motor 46 is fixed to the inner bottom wall of the screening chamber 3. The two bevel gears 45 are respectively fixedly installed on the output shaft of the asynchronous motor 46 and the outer surface of the connecting cylinder 44. The outer surfaces of the two bevel gears 45 mesh with each other. The sliding component is installed between the screen slide 41 and the screening chamber 3.

[0024] The connecting cylinder 44 includes an outer sleeve and an inner sleeve, which are fixedly connected. The inner sleeve has a guide groove, which allows the connecting piece 43 to move up and down continuously through the wavy guide groove.

[0025] In addition, the connector 43 is an integral structure consisting of a support column and two bosses. One end of the support column extends into the interior of the inner sleeve, and the bosses extend into the interior of the guide groove. The bosses and the guide groove are slidably connected. The rotation of the connecting cylinder 44 is converted into the up and down movement of the connector 43, thereby controlling the reciprocating up and down movement of one end of the screen slide 41.

[0026] It should be noted that a limiting plate 49 is fixedly installed on the inner bottom wall of the screening chamber 3 to restrict the range of fine sand, and a guide plate 50 for guiding fine sand is fixedly connected to the bottom of the screen slide 41. The screen slide 41 and the inner bottom wall of the screening chamber 3 form an angle of 30 degrees. After the quartz sand is crushed by the sand making machine 1, it falls into the inclined screen slide 41. Under the action of the reciprocating motion of the screen slide 41, the fine sand falls through the screen to the bottom of the screening chamber 3. The fine sand will be restricted to a specific area by the limiting plate 49 and then guided by the guide plate 50 to the next level of conveying equipment.

[0027] Using the above technical solution, after the asynchronous motor 46 is turned on, its output shaft drives the bevel gear 45 connected to it to rotate. The bevel gear 45 meshes with another bevel gear 45 installed on the outer surface of the connecting cylinder 44, thereby driving the connecting cylinder 44 to rotate. When the connecting cylinder 44 rotates, the guide groove guides the boss to move. Since the connecting piece 43 is fixedly connected to the elastic connecting piece 42 and the screen slide 41, it drives the screen slide 41 to move up and down, thereby providing the screen slide 41 with a disturbance force for up and down action, so that the coarse sand on the screen slide 41 flows more smoothly.

[0028] Example 3: Please refer to Figure 1-6Based on Embodiment 2, the sliding component includes two support members 47 and a connecting rod 48. The two support members 47 are fixedly installed on the screening chamber 3. Each of the two support members 47 has a sliding groove inside. The connecting rod 48 is fixedly connected to one end of the screen slide 41. Both ends of the connecting rod 48 pass through the sliding groove and are slidably connected to the sliding groove.

[0029] Using the above technical solution, when the screen slide 41 moves up and down, the support member 47 restricts the sliding trajectory of the connecting rod 48, so that one end of the screen slide 41 can only move back and forth along the direction of the slide groove, and cooperates with the reciprocating up and down movement of the other end of the screen slide 41 to form a complex motion trajectory, further disturbing the coarse sand on the screen slide 41.

[0030] The working principle of the above embodiments is as follows:

[0031] When the sand making machine used for producing high-purity quartz sand is in use, after the asynchronous motor 46 is turned on, its output shaft drives the bevel gear 45 connected to it to rotate. The bevel gear 45 meshes with another bevel gear 45 installed on the outer surface of the connecting cylinder 44, thereby driving the connecting cylinder 44 to rotate. When the connecting cylinder 44 rotates, the guide groove guides the boss to move. Since the connecting piece 43 is fixedly connected to the elastic connecting piece 42 and the screen slide 41, it drives the screen slide 41 to move up and down, thereby providing the screen slide 41 with a disturbance force for up and down action, so that the coarse sand on the screen slide 41 flows more smoothly.

[0032] When the screen slide 41 moves up and down, the support 47 restricts the sliding trajectory of the connecting rod 48, so that one end of the screen slide 41 can only move back and forth along the direction of the slide groove, and in conjunction with the reciprocating up and down movement of the other end of the screen slide 41, a complex motion trajectory is formed, which further disturbs the coarse sand on the screen slide 41.

[0033] After being crushed by the sand making machine 1, the quartz sand falls into the inclined screen slide 41. Under the action of the reciprocating motion of the screen slide 41, the fine sand passes through the screen and falls to the bottom of the screening bin 3. The fine sand is restricted to a specific area by the limiting plate 49 and then guided to the next stage of the conveying equipment by the guide plate 50. The coarse sand moves down the screen slide 41 and is finally discharged from one end of the screen slide 41, thereby achieving the separation of quartz sand of different particle sizes.
