Description

Technical Field

[0001] The utility model relates to the technical field of screening equipment, in particular to a high-purity quartz sand magnetic separation and vibration screening integrated device. Background Art

[0002] High-purity quartz sand is a basic material for high-end industries such as photovoltaics and semiconductors. Its production process is extremely complex and has extremely stringent environmental requirements.

[0003] The existing quartz sand purification equipment is relatively mature, and there are corresponding equipment for acidification, flotation, magnetic separation, drying, screening and other processes, and they are relatively independent in the production process. This leads to high-purity quartz sand being polluted by the environment or human factors during the transportation process during the production process. This is a fatal consequence for high-purity quartz sand, especially in the last two screening and magnetic separation processes. Any slight contamination will cause irreversible consequences. However, the existing quartz sand magnetic separation and screening purification equipment is relatively independent and cannot completely avoid the environmental pollution or human pollution problems in the process of transferring the high-purity quartz sand after magnetic separation to the screening machine. In order to solve this problem and avoid the pollution caused by the relative independence of screening and magnetic separation, this patent provides a device that can integrate magnetic separation and vibration screening. Utility Model Content

[0004] The purpose of the utility model is to solve the pollution problem of high-purity quartz sand caused by the relative independence of the above-mentioned process equipment. After a lot of research and experiments, a device capable of integrating magnetic separation and vibration screening is developed to solve the problem.

[0005] The utility model is realized by the following technical solutions:

[0006] A high-purity quartz sand magnetic separation and vibration screening integrated device, comprising a magnetic separator, a sealing box is provided at the lower end of the discharge part of the magnetic separator, a vibration screening device is suspended in the sealing box, the vibration screening device comprises an annular screening plate arranged at the lower end of the discharge part, a screening element is provided at the bottom of the annular screening plate, and a vibrator is provided on the outer circle of the annular screening plate.

[0007] As a further configuration of the above solution, a cleaning port corresponding to the vibration screening device is opened on the side of the sealing box, and a sealing cover plate is provided on the cleaning port.

[0008] As a further configuration of the above solution, a collecting tank is provided in the sealed box below the vibration screening device.

[0009] As a further configuration of the above solution, the screening element is a single-layer screening mesh or a double-layer screening mesh with different apertures.

[0010] As a further configuration of the above scheme, a plurality of lifting ears are evenly arranged on the outer circumferential surface of the annular screening disc, a lifting portion is arranged between two opposite lifting ears, and a hook that interacts with the lifting portion is arranged on the top wall of the sealing box.

[0011] As a further configuration of the above scheme, the magnetic separator is a vertical series magnetic separator, including a vertical frame and a magnetic separation cylinder, the magnetic separation cylinder is arranged at the upper end of the vertical frame, the discharge part is arranged at the lower end of the magnetic separation cylinder, and the upper end of the magnetic separation cylinder is provided with a feed part.

[0012] During use of the high-purity quartz sand magnetic separation and vibration screening integrated device disclosed by the utility model, the high-purity quartz sand is added into the magnetic separator by a feeder, and the material after magnetic separation enters the sealing box from the discharge part and falls into the annular screening plate.

[0013] Then start the vibrator synchronously to make the annular screening plate and the screening element vibrate at a high frequency, so that the high-purity quartz sand after magnetic separation can be quickly screened and fall into the collection tank. After running for a period of time, stop the magnetic separation and vibration screening, open the sealing box, take out the screening element on the screening plate for cleaning, and put it back into the annular screening plate after cleaning to carry out the magnetic separation and vibration screening of the next batch of high-purity quartz sand.

[0014] Compared with the prior art, the utility model has at least the following beneficial effects:

[0015] Strong practicality: the self-developed vibration screening device is installed on the original magnetic separator equipment, which can be applied to any magnetic separator and can be dismantled (removed) at any time as needed without affecting the magnetic separation function.

[0016] The pollution degree is small; the vibration screening device is integrated into the magnetic separator to form an integrated equipment, which can reduce the environmental and human pollution caused by high-purity quartz sand during the transportation process and maximize the cleanliness of high-purity quartz sand.

[0017] Save time and labor; this integrated magnetic separation and vibration screening device combines the two original independent devices together, reducing the manual handling steps of high-purity quartz sand and improving production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
