Description

Waste plastic water flotation device

technical field

The utility model relates to a recycling device for waste plastics, in particular to a water flotation device for waste plastics.

Background technique

There are many methods for plastic recycling, and flotation separation is one of the more advanced methods for the separation of mixed plastics. It is usually done with a fluid medium with a density intermediate between the plastics to be separated, plastics less dense than the medium will float up and denser ones will sink. Theoretically speaking, this method is not affected by shape and size, and is especially suitable for separating plastics that are unevenly crushed and have small density differences, and this process can effectively remove food residues on waste plastics. However, the disadvantage of the device used in this separation method is that it produces a large amount of waste water that needs to be specially treated. Today, with more and more emphasis on environmental protection, the device of this separation method is in urgent need of improvement.

Utility model content

The technical problem to be solved by the utility model is to provide an efficient and water-saving waste plastic water flotation device.

In order to solve the above problems, a waste plastic water flotation device described in the utility model is characterized in that the device includes a crusher, a cleaning tank, a primary separation tank, a secondary separation tank, a primary sedimentation tank, a secondary Settling tank and clean water tank; the top of the crusher is provided with a gas delivery pipe, and one side thereof is provided with a feed port, which is connected to the cleaning tank; one side of the primary separation tank is connected to the The cleaning pool is connected, and the other side is connected with the secondary separation pool; one side of the secondary separation pool is connected with a discharge port through a spiral lifting dryer, and a drainage pipe is provided on one side of the bottom. The pipe is connected with the first-level sedimentation tank; one side of the second-level sedimentation tank is connected with the first-level sedimentation tank, and the other side is connected with the clear water tank; one side of the clear water tank is provided with an outlet A water pipe, the outlet pipe is connected with a water pump connected to one end of the filter; the other end of the filter is provided with a filter water pipe, and the filter water pipe is connected to the cleaning pool.

There is a drop of 30-40 cm between the primary sedimentation tank, the secondary sedimentation tank and the clear water tank in turn.

A screen is set inside the spiral lifting dryer.

Compared with the prior art, the utility model has the following advantages:

1. Since the utility model is provided with two-stage separation pools with independent functions, the water efficiency of each sub-pool can be effectively improved.

2. Since the utility model is equipped with a two-stage sedimentation tank and a clear water tank set with a drop, the sediment and sewage are separated by means of the drop gravity, so not only the production cost is reduced, but also the separation efficiency is improved.

3. Since the utility model is equipped with a water circulation device, the cleaning sewage can be recycled after simple treatment, effectively saving water.

Detailed ways

As shown in Figure 1, a waste plastic water flotation device includes a crusher 13, a cleaning tank 5, a primary separation tank 4, a secondary separation tank 3, a primary sedimentation tank 7, a secondary sedimentation tank 8 and a clean water tank 9 .

The top of the crusher 13 is provided with a gas conveying pipe 14, and one side thereof is provided with a feed port 12, and the feed port 12 is connected with the cleaning pool 5; one side of the primary separation pool 4 is connected with the cleaning pool 5, and the other The side is connected with the secondary separation pool 3; one side of the secondary separation pool 3 is connected with the discharge port 2 through the spiral lifting dryer 1 with a screen, and the bottom side is provided with a drain pipe 6. 6 is connected with the primary sedimentation tank 7; one side of the secondary sedimentation tank 8 is connected with the primary sedimentation tank 7, and the other side is connected with the clear water pool 9; one side of the clear water pool 9 is provided with an outlet pipe, and the outlet pipe A water pump 10 connected to one end of the filter 11 is connected;

Among them: the primary sedimentation tank 7, the secondary sedimentation tank 8 and the clear water tank 9 have a drop of 30-40 cm in turn.

When working, the plastic to be sorted first enters the crusher 13, and after being broken into small pieces of 3 to 5 cm, it is blown to the cleaning pool 5 by the gas in the gas delivery pipe 14; After removing dirt and other stains on the material, it enters the primary separation tank 4 and the secondary separation tank 3 for separation. The obtained sediment enters the primary sedimentation tank 7, the secondary sedimentation tank 8, and the clear water pool 9 through the drain pipe 6 successively under the action of the water flow; finally, the water flow reaches the clear water pool 9, and the water pump 10 is used for recycling. After the water is pumped to the filter 11 for processing, it enters the cleaning tank 5 for utilization. The crushed material separated in the primary separation tank and the secondary separation tank is bagged separately after dehydration.
