Problems solved by technology

[0003] (1) The flotation method is applied, that is, salt water of different concentrations is prepared, and the density difference between the density of the salt water of different concentrations and the density of different waste plastics is used for flotation classification; industrial salt; the solution used is high in sewage treatment cost; the treatment process is difficult to automate
This technology generally has the following problems: the effect is good for fragments with uniform volume, but it is difficult for waste plastic fragments to have a uniform volume, so fragments slightly larger than the pit are mixed into fragments with light density. in large fragments

Embodiment 1

[0037] see Figure 1-Figure 4 , the mechanism of the present invention for controllably separating materials of different densities using fluid media includes a straight tank 1, a conveying device 2 arranged in the straight tank 1 for transporting submerged materials, and a separation device for separating materials of different densities 3.

[0038] see Figure 1-Figure 4 , the straight trough 1 is divided into three separation areas along the conveying direction of the material, and the end bottom of each separation area is provided with a material outlet 1-1; the conveying device 2 includes a The first conveying mechanism for conveying the material in this separation area to the material outlet 1-1 of the corresponding separation area and the second conveying mechanism for conveying the material out of the straight tank 1 from the material outlet 1-1.

[0039] see Figure 1-Figure 4 The separating device 3 includes a baffle 3-1 arranged between two adjacent separation ar...

Embodiment 2

[0054] see Figure 5 , The difference between this embodiment and Embodiment 1 is that the first conveying mechanism includes a screw pusher 2-1, and the screw pusher 2-1 is arranged at the bottom of the straight groove 1, and along the The conveying direction of the material extends; the straight groove 1 is provided with a groove matching with the screw pusher 2-1 at a position corresponding to the screw pusher 2-1; the screw pusher 2 The blade of -1 breaks between two adjacent separation regions. Since the screw pusher 2-1 pushes the material through the blades surrounding the screw along the length direction of the screw, when the blades between the adjacent two separation areas in the screw pusher 2-1 are disconnected , when the screw pusher 2-1 transports the material to the disconnected area (refer to the A area in the accompanying drawing), since the disconnected area has no blades, it cannot continue to transport the material forward , so as to ensure that the separ...

Embodiment 3

[0057] see Image 6 , the difference between this embodiment and embodiment 1 is that there are three separation areas in the straight groove 1, and correspondingly, there are two sets of separation devices 3, which are respectively located in the first separation area and the second separation area. within the area. In this way, the mechanism for controllably separating materials with different densities using a fluid medium in the present invention can separate the submerged materials and semi-submerged materials entering the straight tank 1 into three categories and collect them separately.

[0058] Other specific structures of this embodiment are implemented with reference to Embodiment 1.

Abstract

The invention discloses a mechanism for controllably separating materials with different densities by using a fluid medium. The mechanism uses water as a medium, with no need to add salt and the like,and the materials flow unidirectionally in a plug flow manner along with a water flow. The materials with different densities have different sedimentation rates. The mechanism adopts a baffle plate with a controllable height; through adjusting the height of the baffle plate, the materials with different sedimentation rates, namely plastic fragments with different densities, are partitioned and collected, so as to achieve the purpose of distinguishing and collecting the materials with different densities. The mechanism comprises a straight slot divided into multiple separation areas, a conveying device used for conveying the deposited materials to material outlets of the different separation areas, and a separation device; the separation device is a set of baffle plates with adjustable heights, and through adjusting the heights of the baffle plates, the density separation of the materials needing to be separated is flexibly responded to.

Description

technical field [0001] The invention relates to resource recycling and processing equipment, in particular to a mechanism for controllably separating materials with different densities using a fluid medium. Background technique [0002] In many fields, it is often encountered the need to separate materials of different densities; for example, in the recycling process of waste plastics, it is necessary to distinguish various types of plastics, and the densities of different types of plastics are often different. The existing technologies are: [0003] (1) The flotation method is applied, that is, salt water of different concentrations is prepared, and the density difference between the density of the salt water of different concentrations and the density of different waste plastics is used for flotation classification; industrial salt; the solution used is high in sewage treatment cost; the treatment process is difficult to automate. [0004] (2) Inclined shaker method, a b...
