Description

Technical Field

[0001] This utility model relates to the quartz sand washing process, and more particularly to a backwash type high-purity quartz sand ultrasonic multi-stage cleaning machine. Background Technology

[0002] Quartz sand cleaning methods include physical cleaning, chemical cleaning, and high-pressure cleaning. The appropriate process must be selected based on the type of impurities and purity requirements. Physical cleaning – water washing: Quartz sand is placed in a cleaning tank, and loose surface impurities (such as mud and dust) are removed by water flow. The water flow rate must be moderate to avoid damaging the sand grain surface. Physical cleaning – sieving: Vibrating screens or drum screens are used to separate particles and remove large impurities such as branches and shells. This is usually combined with a spray system to improve efficiency. Chemical cleaning – acid washing: Hydrochloric acid, sulfuric acid, hydrofluoric acid, etc., are used to dissolve metal ions or silicate impurities. The acid concentration and soaking time must be controlled to avoid excessive corrosion of the quartz sand. Chemical cleaning – oxidation cleaning: Oxidants such as hydrogen peroxide are used to remove organic contaminants, suitable for high-purity applications. High-pressure cleaning: High-pressure water guns or specialized equipment are used to flush the surface of the quartz sand, efficiently removing stubborn impurities. However, water pressure and soaking time must be controlled to prevent sand grain breakage. These traditional methods all have some problems, therefore a new structure is urgently needed for cleaning quartz sand. Summary of the Invention

[0003] The purpose of this invention is to provide a novel, multi-stage ultrasonic cleaning machine for high-purity quartz sand with a backwash design, featuring layered and step-by-step cleaning and a small footprint.

Detailed Implementation

[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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figure 1-6 As shown, a backwash type high-purity quartz sand ultrasonic multi-stage cleaning machine includes a machine body 1, a control cabinet 2 on one side of the machine body 1, a feed inlet 3 inside the machine body 1, the feed inlet 3 being connected to a cleaning water channel 4, a backwash water inlet pipe 5 inside the cleaning water channel 4, several ultrasonic transducer boxes 6 on the outer wall of the cleaning water channel 4, a thickening cone 7 connected to the cleaning water channel 4, and a discharge pipe 8 connected to the thickening cone 7.

[0023] Preferably, an adjusting plate 9 is provided inside the feed inlet 3, and the diameter of the feed inlet is controlled by rotating the adjusting plate 9.

[0024] Preferably, a sedimentation tank 10 is provided at the upper end of the body 1, and an overflow sewage outlet 11 and a cleaning outlet 13 are provided on the sedimentation tank 10.

[0025] Preferably, the backwash inlet pipe 5 is provided with a plurality of backwash holes.

[0026] Preferably, a pneumatic valve 12 is provided on the discharge pipe 8. The valve opens when a certain amount is reached in the thickening cone and then closes after discharge. Example

[0027] During use, the material enters the machine body 1 (i.e., the cleaning channel 4) through the feed inlet 3. At the same time, the ultrasonic transducer box 6 is activated, and the backwash water inlet pipe 5 is opened to allow water to enter. As the material falls, it experiences vibration from the ultrasonic waves and scouring from the water flow. After repeated vibration and scouring, impurities on the surface of the material are removed.

Finally, the material enters the thickening cone 7, and the cleaned material is discharged and collected from the discharge pipe 8 by controlling the pneumatic valve 12.
