Rotational flow screening equipment

Abstract

The invention aims to provide rotational flow screening equipment. A relatively sealed cylindrical container composed of a side wall, a conical side wall, an upper end face and a lower end face is designed; a driving shaft is arranged on the end surface of the lower part, so that the driving shaft is positioned on the central axis of the barrel body; centrifugal fan blades are arranged on the driving shaft; a feeding hole is formed in the upper end surface or the side wall close to the upper end surface; a first discharging opening is formed in the area, close to the upper end face, of the side wall; a second discharge hole is formed in a combined part area of the side wall and the conical surface side wall; the opening directions of the first discharge port and the second discharge port are both downward or inclined downward, so that airflow circulates in the barrel, the quantity of air flowing out of the barrel is small, the influence of dust on the external environment in the working process is small, closed dust-free operation can be achieved, and the working efficiency is improved. Screening and winnowing can be synchronously completed on materials containing light floccules, and convenience and rapidness are achieved.

Description

technical field [0001] The present application relates to the technical field of industrial equipment, and in particular, to a cyclone screening equipment. Background technique [0002] Screening machines are commonly used equipment in the current industrial field. There are three main types of existing screening machines: one is an oscillating screener; the other is a drum screener; the third is an air separator. The main function of the first two types is to separate solid particles of different particle sizes, and the main function of the third type is to separate light flocs, such as seed coats and broken leaves in agricultural products. The existing screening technology mainly has the following defects: First, the screen needs to vibrate, rotate and other actions during the screening process, so the screening process cannot be completed in a closed chamber, and the dust is flying during the working process, which is relatively polluting to the environment. The second i...

AI Technical Summary

Problems solved by technology

The existing screening technology mainly has the following defects: First, the screen mesh needs to vibrate, rotate and other actions during the screening process, so the screening process cannot be completed in a closed chamber, and the dust is flying during the working process, which is more polluting to the environment. The second is that there are many dead spots, and cleaning is difficult; the third is that the two functions of winnowing and screening cannot be realized simultaneously, and need to be completed in two devices successively, which is time-consuming and laborious
