Separator for separating grass and trees from plastic films

Abstract

The invention discloses a separator for separating grass and trees from plastic films. The separator comprises a case, a screen drum, a spindle and a dust suction device, wherein the screen drum is axially and horizontally fixed in the case, a feed inlet is arranged at one end of the screen drum, a discharge outlet is arranged at the other end of the screen drum, the spindle is installed at the center of the screen drum in a rotating mode and driven by a spindle power device, the spindle is provided with a pushing screw blade section, a centrifugal scattering screw blade section and a discharging blade section, the pushing screw blade section and the discharging blade section correspond to the feed inlet and the discharge outlet respectively, the centrifugal scattering screw blade section is positioned between the pushing screw blade section and the discharging blade section, the dust suction device is communicated with the inner cavity of the case, an impurity collecting cavity is disposed at the bottom of the case, and an impurity discharge port is formed in the wall of the impurity collecting cavity. The separator can separate impurities in films, such as grass, trees and dust automatically and continuously, so that the separating efficiency of the impurities in agricultural film recovery is improved, and requirements for agricultural film recovery production lines are met.

Description

technical field [0001] The invention relates to a plastic machine, in particular to a plastic film vegetation separator. Background technique [0002] In the current plastic machinery industry, how to remove impurities in films has always been a difficult problem, especially the removal of impurities in agricultural films. Agricultural film refers to the film used in agricultural production. For example, a large number of films are required in vegetable greenhouses. These films are aged and unusable after being exposed to the sun and rain. However, the amount of agricultural film is very large. If the agricultural film can be recycled and reused Membrane, it is not only beneficial to environmental protection, saving materials and energy, but also can generate great economic value. However, there will be some dry vegetation and powder dust in the recycled agricultural film. These vegetation and dust are difficult to separate from the film. At present, there is no effective s...

Problems solved by technology

However, there will be some dried vegetation and powder dust in the recycled agricultural film. These vegetation and dust are difficult to separate from the film. At present, there is no effective separation machine. The usual method is multiple screening and separation, which is not only time-consuming and laborious, but also cannot be continuous. Production
