Technical Field

[0001] The utility model relates to the technical field of detection and screening devices, in particular to a detection and screening device for corundum production. Background Art

[0002] Detection and screening device, also known as screening device, corundum production is a complex and delicate process, mainly involving raw material preparation, grinding and mixing, molding, drying and pre-firing, sintering and post-processing and other links. Jade production usually uses high-purity alumina as the main raw material. These raw materials can be natural ores or chemically synthesized powders. For certain types of corundum (such as plate-shaped corundum), pure alumina powder without any additional additives may be selected. When powdered alumina or aluminum powder is used as raw material, the raw materials containing alumina powder or aluminum powder must be detected and screened to remove large particles of impurities. During screening, because aluminum powder and alumina powder are both powdered, a closed vibrating screening device must be used for screening. Otherwise, not only will a large amount of aluminum powder or alumina powder be wasted, but it will also cause harm to the health of surrounding personnel.

[0003] In the prior art, a patent document with application number CN202020479400.6 reviewed and published by the State Intellectual Property Office of China discloses a device for preventing blocking in house construction, comprising a screen box, an elastic seat, a vibration motor, a stirring assembly, a sand inlet, a filter screen, a stone outlet and a sand outlet, wherein the sand outlet is arranged directly below the filter screen, and a control device is provided on the outer wall of the screen box, and the vibration motor and the stirring assembly are electrically connected to the control device; in actual application, the sand to be screened is put into the sand inlet, and when the control device controls the vibration motor to vibrate the screen box left and right, the elastic seat vibrates the screen box up and down under the action of the vibration motor, and at the same time the stirring assembly stirs the sand inside the screen box, and the fine sand falls to the sand outlet through the filter screen, and the coarse gravel is discharged from the stone outlet; the utility model fully automatically and efficiently screens sand, saves human labor, and the closed box is not easy to fly ash, protects the health of workers, and effectively prevents screen jamming.
