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 Example 1: The structure 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, and the other end is provided with a discharge port 530, and a washing chamber is provided in the body 520, and a drum is provided in the washing chamber. Three drums are arranged in sequence between the feed port and the discharge port, namely the first drum 541, the second drum 542 and the third drum 543;

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

[0042] One end of the body 520 adjacent to the feed port 510 is provided with an upper ...

Embodiment 2

[0046] Device Embodiment 2: The structure is basically the same as that of Device Embodiment 1, and the similarities will not be described again. The difference is:

[0047] Five drums are arranged in turn between the feed inlet and the discharge port; two sets of blades are arranged on the runner of the same drum, and the two sets of blades have the same feeding direction along the tangential direction of the runner. The direction of material shifting in the axial direction of the wheel is relative.

[0048] Each of the lower water inlets is correspondingly equipped with a flow rate control device, each of the pipes is correspondingly equipped with a flow meter, and each of the upper discharge valves and the corresponding lower discharge valves are automatic valves that open and close alternately 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 multi-drum type material washing separation method:

[0051] The mixed material is solid waste from paper mills, and its 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-type waste plastic materials. piece. Here, the multi-drum washing and separating device provided by the device embodiment 1 is used to wash and separate the solid waste in the paper mill: the linear speed of the outer circle of the three drums arranged in sequence between the feed port and the discharge port It is 1.2m / s, and the weight ratio of dry mixture material to 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 washing water is injected...

Abstract

The invention discloses a multi-rotor drum type washing and separating device. A pipe body is arranged below the inverted frustum-shaped bottom of a machine body, lower water inlets are formed in the side wall of the pipe body, a sinking pipe, an upper unloading valve and a lower unloading valve are arranged below the pipe body, and the upper unloading valve and the lower unloading valve can be opened or closed alternately, so that a material mixture of different proportions is effectively washed and separated. The invention further discloses a multi-rotor drum type material washing and separating method. Through the method that washing water is injected from upper water inlets and the lower water inlets at the same time and the upper unloading valve and the lower unloading valve are opened or closed alternately, the upstream flow velocity of the washing water injected from the lower water inlets is controlled through the different proportions of the different materials in the material mixture, and the different materials differing in proportion are washed and separated effectively. Furthermore, by configuring the upstream flow velocity of the washing water injected from the lower water inlets to be decreased sequentially and gradually, the material mixture progressive separation and incremental settlement effect is obtained. Meanwhile, the water flow velocity can be controlled more accurately through a flow velocity control device and the flow meter. By means of the automatic valves, automatic stacking and automatic unloading are achieved, and production continuity is ensured.

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...
