Screening mechanism with dual screening function

Abstract

The invention discloses a screening mechanism with a dual screening function. The screening mechanism comprises a mechanism body, a first supporting base is arranged on the left side of the mechanismbody, a water tank is arranged on the first supporting base, a water pump is connected to the water tank through a water pipe and connected to the interior of the mechanism body through a water pipe,and sprinkler heads are arranged at the bottom end of the water pipe; a feeding port is installed on the right side of the mechanism body, and one end of the feeding port penetrates through the uppersurface of the mechanism body and extends into the mechanism body; a second supporting base is fixedly installed on the right side of the mechanism body, a supporting rod is fixedly installed on the upper surface of the second supporting base, and a conveyer belt is fixedly connected to the top end of the supporting rod; and a first screen mesh is installed in the mechanism body, and a second screen mesh is arranged at the lower end of the first screen mesh in parallel. According to the screening mechanism with the dual screening function, the first screen mesh, the second screen mesh, springs, bouncing balls, damping springs and the like are arranged, and therefore the problems that in the prior art, a screening mechanism is single in structure and low in working efficiency, materials cannot uniformly fall to the screen meshes, and the screening effect is bad are solved.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment, in particular to a screening mechanism with double screening. Background technique [0002] Sieving is a method of separating particle groups according to particle size, specific gravity, chargeability, magnetic properties and other powder properties, and uses a perforated sieve surface to divide mixed materials with different particle sizes into various particle size levels. [0003] There are following deficiencies in the prior art: [0004] 1. The screening equipment in the prior art is usually equipped with a layer of screening structure. The sieved materials are not fine enough, the mixture is often not completely separated, the work efficiency is low, and the materials cannot reach the screen evenly. Excessive amounts can easily cause accumulation. The sieving effect is not good. [0005] 2. The screening equipment in the prior art does not have a shock absorbing device, and ...
