Anti-blocking feed chute of aggregate separator

Abstract

The invention provides an anti-blocking feed chute of an aggregate separator, and relates to the technical field of aggregate separation. The anti-blocking feed chute comprises a feed chute body, a feeding pipe and an air inlet pipe; one end of the air inlet pipe penetrates through the pipe wall of the feeding pipe to communicate with the feeding pipe; the other end of the air inlet pipe communicates with an air pump, and the air inlet direction of the air inlet pipe faces an aggregate separator body. According to the anti-blocking feed chute of the aggregate separator, in the process that thefeed chute body conveys concrete excess materials to the aggregate separator body, the air pump is started, generated air flow is sprayed to the aggregate separator body, the flowing speed of the concrete excess materials at the communicating position between the feeding pipe and the air inlet pipe is increased, negative pressure is generated, suction force for sucking the concrete excess materials in the feeding groove body into the feeding pipe is provided, the flowing speed of the concrete excess materials at the pipe opening of the feeding pipe is increased, and the concrete excess materials are effectively prevented from being condensed and blocked at the pipe opening of the feeding pipe.

Description

technical field [0001] The invention relates to the technical field of sand and gravel separation, in particular to an anti-blocking feed trough of a sand and gravel separator. Background technique [0002] With the gradual enhancement of people's awareness of environmental protection and the continuous increase of the government's environmental protection efforts, more and more attention has been paid to the waste pollution problem of concrete mixing plants. The remaining material is solidified in the concrete truck and needs to be washed with a large amount of water. The water used for cleaning contains a large amount of insoluble matter such as cement and sand. If it is discharged to the river without treatment, it will cause serious pollution and waste a lot of waste of tap water and concrete materials. [0003] Therefore, under the country's policy of actively advocating the construction of environmentally friendly mixing plants, more and more concrete mixing plants ha...
