Background

Waste plastics, which are a type of waste that has a great environmental impact, are generally disposed of for recycling or degradation.

The flotation is to distinguish the plastics with different densities by judging whether the plastics can float on the surface of the flotation solution according to the properties of the plastics with different densities. The device for recycling and floating the waste plastics, disclosed in chinese patent publication No. CN109849225A, comprises a flotation liquid tank and a flotation treatment tank, wherein the flotation liquid tank is filled with flotation liquid, an automatic feeder is arranged above the flotation treatment tank and used for adding plastic raw materials to be floated into the flotation treatment tank, the flotation liquid tank is of a closed structure, an upper outlet and a lower outlet of flotation materials are respectively arranged above and at the bottom of the flotation treatment tank, and plastics with different densities respectively float on the surface of the flotation liquid or sink at the bottom and are respectively discharged through the upper outlet and the lower outlet.

However, the above-described construction, in which both the upper outlet and the lower outlet are conventional tubular outlets, i.e. the plastic is discharged with the flotation liquid, is a costly operation for the flotation liquid, and even if the discharged flotation liquid is recycled, the flotation liquid may be contaminated during this period and is difficult to use directly.

SUMMERY OF THE UTILITY MODEL

Therefore, the to-be-solved technical problem of the utility model lies in overcoming the flotation solution among the prior art and along with the defect of a large amount of discharge of plastics easily to provide a material structure is selected out to abandonment plastics recovery flotation.

And two ends of the spiral blade respectively extend into the flotation treatment tank and extend out of one end of the discharge pipe deviating from the flotation treatment tank.

The discharge gate divide into the first discharge gate that is located flotation treatment tank deck portion and the second discharge gate that is located flotation treatment tank bottoms portion, flotation treatment tank's bottom is the slope setting, and the vertical height in one side that is close to the second discharge gate is minimum.

The top of the discharge pipe of the first discharge port is higher than the top of the flotation treatment tank.

The bottom of the discharge pipe of the second discharge port is lower than the lowest position of the bottom of the treatment tank.

One end of the discharge pipe, which is far away from the flotation treatment tank, is provided with a hollowed-out net surface.

The utility model discloses technical scheme has following advantage:

1. compared with a conventional tubular discharge port, the helical blade in the scheme can effectively filter the flotation solution to obtain only solid plastics when the plastics are obtained.

2. The utility model provides a discharging pipe that slope set up can be convenient for flow back to the flotation treatment jar by the flotation solution that a small amount of belt were played.

3. The utility model provides a top, the bottom setting of flotation treatment jar are all outstanding to the discharging pipe, and the plastics that can be convenient for fall in helical blade department are driven by helical blade and are released outside the discharging pipe. If the tapping pipe is raised above the top of the flotation tank, the plastic can be seen as floating in the middle of the tapping pipe when it is in the middle to receive plastic, since the plastic floats on the surface of the flotation liquid, and more plastic can enter the tapping pipe per unit time.

Examples

The utility model provides a material structure is selected by flotation to waste plastic recycling, includes airtight flotation treatment tank 1 that sets up, is located the flotation liquid of flotation treatment tank 1, the top and the bottom of flotation treatment tank 1 are equipped with the discharge gate, and the discharge gate is used for the plastics discharge flotation treatment tank 1 after the flotation. Due to the difference in density between the plastic and the flotation liquid, the plastic may float on the surface of the flotation liquid, or sink to the bottom of the flotation tank 1, or float in an intermediate position in the flotation liquid. In the present embodiment, the more common plastic floats on the surface of the flotation solution, and the plastic sinks on the bottom of the flotation processing tank 1 for analysis, so in the present embodiment, the first discharge port 2 is disposed at the top of the flotation processing tank 1, and the second discharge port 3 is disposed at the bottom of the flotation processing tank 1.

Each discharge hole comprises a discharge pipe 21 for outputting plastics and a helical blade 22 positioned in the discharge pipe 21 for pushing the plastics to advance, and the central axis of the helical blade 22 is coaxial with the cylindrical discharge pipe 21. In order to facilitate the return of the entrained flotation process liquid to the flotation process tank 1, the angle between the discharge pipe 21 and the horizontal plane is set so as to point obliquely to the side facing away from the ground. In this embodiment, the inclination angle is between 7 and 45 degrees, and if the inclination angle is too low, less than 7 degrees, the flotation liquid is more likely to adhere to the plastic and be carried out of the discharge pipe 21.

Two ends of the spiral blade 22 respectively extend into the flotation processing tank 1 and extend out of one end of the discharge pipe 21 departing from the flotation processing tank 1. The helical blades 22 extend into the flotation tank 1 in order to obtain more plastic per unit of time and extend out of the tapping pipe 21 in order to push the plastic out of the tapping pipe 21.

The bottom of the flotation processing tank 1 is obliquely arranged, and the vertical height of one side close to the second discharge port 3 is the lowest. The top of the discharge pipe 21 of the first discharge port 2 is higher than the top of the flotation treatment tank 1, and the bottom of the discharge pipe 21 of the second discharge port 3 is lower than the lowest position of the bottom of the treatment tank. In this embodiment, the diameter positions of the two discharging pipes 21 are connected to the top and bottom of the flotation processing tank 1, and the part of the discharging pipe 21 protruding out of the flotation processing tank 1 is welded to the flotation processing tank 1 in a circular arc shape.

The discharge pipe 21 is provided with a hollowed-out net surface 23 at one end deviating from the flotation treatment tank 1, that is, one section of the discharge pipe 21 is hollowed out, so that after the flotation solution is filtered out through the previous inclined arrangement and the driving of the helical blades 22, the flotation solution adhered to the plastic in a very small amount is dried by applying airflow through the air pump, or is directly dried naturally, of course, the method belongs to an optimization measure, and the consumed flotation solution is very little and can be ignored.

It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious variations or modifications can be made without departing from the scope of the invention.
