Description

Technical Field

[0001] This application relates to the technical field of screening devices, and particularly to a screening device for quartz stone raw materials. Background Art

[0002] Quartz stone is a non-metallic mineral raw material widely used in fields such as construction, chemical industry, and metallurgy.

[0003] However, during the mining and processing of quartz stone, some metal particles such as iron, aluminum, and copper are often mixed in; these metal particles will affect the purity and performance of quartz stone products. Therefore, a vibrating screen is usually used for impurity removal operations. However, although the traditional vibrating screen screening method can remove some particulate impurities, the removal effect of metal particles is not ideal. Utility Model Content

[0004] The problem to be solved by this application is that when the existing quartz stone uses a vibrating screen for metal particle removal operations, metal particles with smaller particle sizes cannot be removed by particle size screening.

[0005] To solve the above technical problems, this application provides a screening device for quartz stone raw materials, including a frame for basic support. A screening component that performs metal particle removal operations by rotating magnetic attraction is arranged on the upper part of the frame, and a material bin for feeding quartz stone raw materials and separating and discharging after screening is covered outside the screening component.

[0006] Since the screening device of this application is designed with a screening component and a material bin, it can not only realize the removal operation of metal particles in quartz stone raw materials through the screening component, but also realize the anti-mixing feeding and separated discharging operations of quartz stone and metal particles through the material bin, solving the problem that when the existing quartz stone uses a vibrating screen for metal particle removal operations, metal particles with smaller particle sizes cannot be removed by particle size screening.

[0017] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application. Embodiment

[0018] The present application relates to a quartz stone raw material screening device. As Figures 1-9 shown, the screening device includes a frame 4 for basic support. The upper part of the frame 4 is provided with a screening component 3 for removing metal particles by means of rotary magnetic attraction. And outside the screening component 3 is covered with a bin for feeding quartz stone raw materials and separating and discharging after screening.

[0019] The screening component 3 includes a motor 9, a shaft rod 10, and a roller 11. The roller 11 is horizontally arranged inside the frame 4 and is connected through the shaft rod 10. The two ends of the shaft rod 10 are connected to the frame 4 through bearing seats. And on the upper part of the frame 4 is arranged a motor 9 capable of driving the shaft rod 10 to rotate. In order to remove metal particles in quartz stone by means of the roller 11, therefore, the roller 11 is of a hollow structure, and inside it is provided with a magnet 14 having a magnetic attraction effect. In order to facilitate the collection of the adsorbed metal particles, therefore, the magnet 14 is statically arranged inside the roller 11 and only produces a magnetic attraction effect on 1 / 2 - 3 / 4 of the circumference of the roller 11. In order to facilitate the arrangement of the magnet 14, therefore, the magnet 14 is arranged on the upper part of the shaft rod 10 through a bearing, and at one end is arranged a dial rod 13 connected to it so as to be able to change its arrangement angle inside the roller 11.

[0020] The silo is divided into a detachable upper silo body 2 and a lower silo body 5. At the lower part of the lower silo body 5, discharge ports 7 for discharging operations are symmetrically arranged. The discharge port 7 on the left is used to discharge quartz stones, and the discharge port 7 on the right is used to discharge metal particles. In order to prevent the discharge ports 7 from having short-term accumulation due to large discharge volume, resulting in secondary mixing of quartz stones and metal particles, therefore, a baffle 8 for blocking is arranged between the discharge ports 7. And on the upper part of the upper silo body 2, a sieve plate 1 for screening the particle size of the quartz stone raw material is arranged. In order to prevent the quartz stone raw material falling along the upper silo body 2 from accidentally sliding down along the surface of the roller 11 to the discharge port 7 for discharging metal particles, therefore, the material falling port 6 at the lower part of the upper silo body 2 is arranged with a center bias to the left, so that the falling quartz stone raw material is biased towards the left half side of the roller 11.

[0021] In order to prevent the quartz stones from sliding significantly on the surface of the roller 11, therefore, a plurality of blocking strips 12 for separating and blocking are evenly arranged on the surface of the roller 11.

[0022] During use, the quartz stone raw material is poured down through the sieve plate 1 of the upper silo body 2. If necessary, the side baffle of the upper silo body 2 can be appropriately heightened to prevent the quartz stones from accumulating and overflowing due to slow falling speed. Then, the quartz stones with qualified particle size will pass through the sieve plate 1 and then fall onto the surface of the roller 11 along the material falling port 6. Since the motor 9 has an amplitude when rotating, therefore, the sieve plate 1 can temporarily not be equipped with an additional vibration source. If the amplitude cannot meet the requirements, a vibration motor 9 can be additionally configured to assist the feeding operation, and the sliding action is slowed down under the blocking of the blocking strips 12. Then, the metal particles mixed in the quartz stones are adsorbed on the surface of the roller 11, and the quartz stones roll along with the roller 11 until they lose the support for them, and then are discharged through the discharge port 7 on the left side of the lower silo body 5. The adsorbed metal particles just lose the suction of the magnet 14 when they reach the discharge port 7 on the right side of the lower silo body 5 and then fall off, and then are discharged through the discharge port 7 on the right side, thus completing the screening operation between the quartz stones and the metal particles.
