Material screening device

Abstract

The invention discloses a material screening device which comprises a swing box rack, wherein a screening box is arranged on the swing box rack; an air blowing device is arranged at the top end of the screening box; an air suction device is arranged at the bottom end of the screening box; a material storage device is arranged at the upper part of the air blowing device; each of the air blowing device and the air suction device comprises a fan; the screening box comprises a screening box outer wall, discharge hole open / close doors and screens; a plurality layers of the screens are arranged in the screening box; the screening box outer wall at the upper end of each screen is provided with one discharge hole open / close door; the screening box can swing in an inclining manner on the swing box rack. According to the material screening device disclosed by the invention, a negative pressure airflow is formed at the inner part of the device in a fan blowing manner, so that materials and the airflow enter the material screening device in a rotating manner, so that the screening action can be more effectively performed. The material screening device can be used at relatively stable places, as well as can be used at some places with special requirements where the site conditions are relatively complicated and the screening needs to be detected in real time.

Description

technical field [0001] The invention relates to a material screening device, which integrates the functions of feeding, automatic screening and material dumping. Efficient and thorough screening and collection of materials. Background technique [0002] In the production process of various materials and some test requirements, it is necessary to conduct detection and experimental analysis of the particles of the material. The general method is to sample them, and after real-time processing, they will be fully screened and processed according to the test procedures. Heavy. The common method now is to put the material into the screening device after sampling, and add a dynamic vibrating device at the bottom of the screening work. The vibrating device provides a strong vibrating action for screening. After the screening, manual intervention is required to remove the The material is taken out for weighing, the overall action requires a long cycle, and the amount of manual inte...

The current general method is to put the material into the screening device after sampling, and add a dynamic vibrating device at the bottom of the screening work. The vibrating device provides a strong vibrating action for screening. After the screening, manual intervention is required to remove the The material is taken out for weighing, the overall action requires a long cycle, and the amount of manual intervention is large, and the existing screening equipment has high requirements on the site, and it does not have good versatility in more complicated places, especially the vibrating mechanism. On-site requirements are greater
