Description

Technical Field

[0001] The invention relates to the technical field of silica sand cleaning, and more specifically to a silica sand cleaning device for solar photovoltaic glass. Background Art

[0002] Silica sand, also known as silicon dioxide or quartz sand, is the core raw material of silicon raw materials and plays an irreplaceable and important basic role in the production and supply of silicon raw materials. Silica sand is the main raw material of solar photovoltaic glass and accounts for a relatively high proportion of glass components. During the glass melting process, silica sand reacts chemically with other raw materials (such as soda ash, limestone, etc.) at high temperatures to form the main structure of the glass. Its high content of silicon dioxide provides the basic skeleton of the glass and determines the basic physical and chemical properties of the glass, such as hardness, wear resistance and chemical stability.

[0003] Before using, silica sand needs to be cleaned to remove impurities in it to avoid affecting the quality of the produced solar photovoltaic glass. Currently, the device for cleaning silica sand usually uses a stirring structure to stir silica sand and water, and then filters them.

[0004] However, the above-mentioned prior art still has the following problems when in use: when the silica sand is cleaned in a stirring manner, some impurities cleaned from the silica sand will stick to the silica sand and the stirring structure during drainage, thereby reducing the purity of the silica sand. Based on this, the present invention provides a silica sand cleaning device for solar photovoltaic glass with high cleaning purity. Summary of the invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a silica sand cleaning device for solar photovoltaic glass. Through the cooperation of a partition, two curved cleaning pipes and a spiral conveying mechanism, silica sand and water can repeatedly flow from top to bottom in a cleaning box, so that the silica sand can be repeatedly cleaned, and the silica sand at the bottom of the inner cavity of the cleaning box can continue to flow, thereby improving the purity of the silica sand. There is no need for a complex and large-area equipment structure, and the cleaning rate is high, so as to solve the problems arising from the above-mentioned background technology.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] Refer to the instruction manual Figure 1-10The present invention provides a silica sand cleaning device for solar photovoltaic glass, comprising a cleaning box 1, a wastewater tank 2 and a material receiving box 3 for cleaning silica sand for solar photovoltaic glass. A cleaning assembly 4 is arranged inside the cleaning box 1, and the cleaning assembly 4 comprises a partition 401 fixed inside the cleaning box 1, and one side of the bottom end of the partition 401 is connected to two curved cleaning pipes 402 distributed front and back, and a plurality of auxiliary cleaning mechanisms 403 are fixedly arranged on the two curved cleaning pipes 402. A spiral conveying mechanism 5 is fixedly penetrated at the center of the bottom end of the partition 401, which is used to convey the silica sand at the bottom of the cleaning box 1 to above the partition 401, and a plurality of first filter plates 6 are fixedly penetrated at the bottom end of the cleaning box 1.

[0035] In addition, the bottom end of the cleaning tank 1 extends to the inside of the wastewater tank 2, and a second filter plate 12 and a water pump 13 are fixedly provided inside the wastewater tank 2.
