Problems solved by technology

But there is a problem: the pieces of paper sinking at the bottom of the ditch need to be cleaned regularly, and the cleaning time is long, which seriously affects the continuity of production; in order to take into account the production capacity, production cycle and continuity of production, it is necessary to expand the sediment ditch. Length and depth, which will lead to a large footprint and space, which cannot meet the requirements of continuous and large-scale production

Embodiment 1

[0040] Device embodiment 1 ： The schematic structural diagram of the multi-drum washing and separating device in this embodiment is as follows: figure 1 As shown, it includes a body 520, the upper part of one end of the body 520 is provided with a feed port 510, the other end is provided with a discharge port 530, the body 520 is provided with a washing cavity, and the washing cavity is provided with a rotating drum, Three drums are arranged in sequence between the material outlet and the material outlet, namely the first drum 541, the second drum 542 and the third drum 543;

[0041] The bottom shape of the body 520 is in the shape of three inverted truncated cones, and the positions of the inverted truncated cones correspond to the positions of the drums one-to-one, and are located below the corresponding drum positions; the inverted truncated cones are the upper mouth and the lower mouth. Small frustum.

[0042] One end of the body 520 adjacent to the feed port 510 is p...

Embodiment 2

[0046] Device embodiment 2 ： The structure is basically the same as that of the first embodiment of the device, and the similarities will not be repeated. The differences are:

[0047] Five rotating drums are arranged in sequence between the feeding port and the discharging port; two sets of blade groups are arranged on the runner of the same rotating drum, and the two sets of blade groups have the same feeding direction along the tangential direction of the runner. The direction of the material in the axial direction of the wheel is opposite.

[0048] Each of the lower water inlets is provided with a flow rate control device, and each of the pipes is provided with a flow meter correspondingly. The upper discharge valve and the corresponding lower discharge valve are automatic valves that alternately open and close at intervals. .

[0049] Embodiment 1 is a preferred embodiment of the multi-drum washing and separating device of the present invention.

Embodiment 3

[0050] Method embodiment 3 ： This is the embodiment of the multi-drum type material washing separation method:

[0051] The mixed material is a paper mill solid waste, and the main components are polypropylene film-based waste plastic sheets and wet-strength paper sheets, that is, the first type of material is wet-strength paper sheets, and the second type of material is polypropylene film-based waste plastic material piece. Here, the multi-drum type washing and separating device provided by the device example 1 is used to wash and separate the solid waste in the paper mill: the outer circle linear velocity of the three drums arranged in sequence between the feeding port and the discharging port is set. It is 1.2m / s, and the weight ratio of the dry mixture to the washing water is 3:97, that is, the washing concentration is 3%.

[0052] The mixed material is fed into the washing chamber through the feed port of the multi-drum washing and separating device; while the washing ...

Abstract

The invention discloses a multi-drum type washing and separating device. A pipe body with a lower water inlet on the side wall is arranged under the inverted frustum-shaped bottom of the machine body, a sinking pipe is arranged under the pipe body, and upper and lower unloading materials are alternately opened and closed. The valve can effectively wash and separate mixed materials with different specific gravity. At the same time, a multi-drum type material washing and separation method is disclosed. The washing water is injected through the upper and lower water inlets at the same time, and the method of alternately opening and closing the upper and lower discharge valves is used to control the specific gravity of different materials in the mixed material. The upward flow rate of the washing water injected into the water inlet can effectively wash and separate different materials with different specific gravity. Further, the progressive separation and incremental deposition effect of the mixed material can be obtained by configuring the ascending flow rate of the washing water injected into each of the lower water inlets in descending order. At the same time, the water flow rate can be controlled more precisely through the flow rate control device and the flow meter, and the automatic valve can automatically accumulate and unload the material to ensure the continuity of production.

Description

technical field [0001] The invention relates to a washing and separating device and a material washing and separating method, in particular to a drum type washing and separating device and a material washing and separating method. Background technique [0002] Paper mills that use waste paper as raw materials will produce 5-8% solid waste per ton of waste paper, the main components of which are waste plastics such as polypropylene and polyethylene films and wet-strength paper sheets. Both waste plastics and wet-strength paper are valuable resources that can be recycled. However, due to the large difference in their physical properties and their mixing together, they need to be fully separated before they can be classified and recycled. Therefore, washing and separation equipment is the key to a comprehensive recycling system. [0003] The existing washing and separation technologies all use sediment ditch or sediment tank as the washing and separating device. After the waste...
