Embodiment Construction

[0009] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further elaborated below in conjunction with specific embodiments and illustrations.

[0010] Such as figure 1 As shown, a method for cleaning quartz sand, first, the quartz sand is added into the metal bottle body 5 provided with a screen 3 through the material inlet 2, and at the same time, the metal bottle body 5 is passed into the metal bottle body 5 from the bottom end of the metal bottle body 5. Compress the air, blow the quartz sand, make the quartz sand particles boil in the metal bottle body 5 and collide and rub against each other, and the quartz sand particles collide with each other and rub to remove surface impurities, and then pass through the screen 3 and are drawn out of the metal bottle by the exhaust fan body 5, the metal bottle body 5 bottom is provided with a dividing plate 1 with air holes, an...

Abstract

The invention provides a method for cleaning quartz sands, relating to the technical field of dry method cleaning and the technical field of pneumatic conveying. The method comprises the following continuous steps: adding quartz sands into a metal bottle body with a screen through a material inlet, and introducing compressed air into the metal bottle body from the bottom of the metal bottle body; blowing air to the quartz sands to ensure that the quartz sand particles in the metal bottle body are in a boiling state to perform mutual impact and friction; and extracting the quartz sand particles from the metal bottle body through the screen after impurities on particle surfaces are removed by mutual impact and friction of the quartz sand particles. In the method, the quartz sands are boiled in the metal bottle body by utilizing a pneumatic conveying technology, the quartz sand particles perform mutual impact and friction to remove impurities on the surfaces; and qualified quartz sand particles can be obtained through separation of the screen. The quartz sands cleaned by the method do not require acidic lotion which is necessary in the traditional sand cleaning method, and avoids steps of drying after wet method cleaning.

Description

Technical field: [0001] The invention relates to the technical field of dry cleaning and pneumatic conveying, in particular to a method for cleaning quartz sand. Background technique: [0002] Quartz sand is a very important raw material. To produce high-quality quartz products, the raw material quartz sand must be pretreated, such as cleaning and purification. In the prior art, the cleaning and purification of quartz sand is usually done under an open system. Putting the sand in the container and soaking it with acidic washing liquid is a static process. Its disadvantages are: the impurity components dissolved in the solution cannot be effectively separated, the speed of impurity removal is slow, and there are many impurities remaining in the sand. , this process cannot produce high-purity quartz sand. Invention content: [0003] The technical problem to be solved by the present invention is to provide a method for cleaning quartz sand without water and other reagents. ...
