Problems solved by technology

At present, most of the oil-stone separation devices use a large tank. After the waste asphalt pavement is crushed, it is soaked in solvent oil in the large tank. In this way, it takes about two days to process a tank of waste asphalt pavement. Not only the work efficiency is low, but also every time New solvent oil is used for each immersion. After the treatment, the concentration of asphalt in the solvent oil is low, and it takes a long time to recover the same amount of asphalt
Later, in order to reduce the soaking time, stir in the oil stone separation tank, the soil is mixed in the mixed oil, when separating the asphalt, the asphalt contains more soil and the performance is poor

Embodiment 1

[0042] The first step is to crush the waste asphalt pavement

[0043] The transported asphalt pavement is crushed into blocks by a pulverizer to obtain crushed waste asphalt pavement;

[0044] The second step, loading

[0045] Close the discharge door, put the crushed waste asphalt pavement into the tank through the feed port, and leave a certain space at the top of the tank;

[0046] The third step, add new solvent oil

[0047] Open the second valve on the solvent filling pipe, add new solvent oil into the tank, the injected solvent oil flows down along the gap between the crushed waste asphalt pavement, and enters the filtrate cavity and solvent oil temporary storage tank through the filter baffle , with the increase of solvent oil, the liquid level of solvent oil is higher than the upper surface of waste asphalt pavement pulverization;

[0048] The fourth step, cycle cleaning and soaking

[0049] When the solvent oil in the solvent oil temporary storage tank reaches a c...

Abstract

The invention belongs to the technical field of equipment for separating asphalt from stone in waste and used asphalt pavements and discloses an oil-stone separating tank and an oil-stone separating method. The oil-stone separating tank is mainly and technically characterized by comprising a tank body, wherein the upper end of the tank body is provided with a feed inlet and a solvent inlet, whilethe lower end is provided with a discharge outlet and a solvent outlet; a discharge door capable of opening and closing is arranged in the tank body and at a position close to the lower side, the discharge door has a two-layer structure, the upper surface of the discharge door is a filter baffle, the middle is a filtrate chamber which is communicated with the solvent outlet, the solvent outlet isconnected with the solvent inlet through a circulating oil pipe which is positioned outside the tank body, and the circulating oil pipe is connected with a mixed oil output pipe and a solvent compensating pipe; and the mixed oil output pipe is provided with a first valve and the solvent compensating pipe is provided with a second valve. Thus, the obtained asphalt basically avoids slit and has high quality.

Description

technical field [0001] The invention belongs to the technical field of asphalt and gravel separation equipment in waste asphalt pavement, and in particular relates to an asphalt separation tank. Background technique [0002] After the damaged asphalt pavement is peeled off, due to technical reasons, it is often thrown away as garbage, which not only causes waste, but also causes environmental pollution. The asphalt is removed by solvent oil in the oil stone separation tank and separated Collect asphalt and gravel for disposal. At present, most of the oil-stone separation devices use a large tank. After the waste asphalt pavement is crushed, it is soaked in solvent oil in the large tank. In this way, it takes about two days to process a tank of waste asphalt pavement. Not only the work efficiency is low, but also every time New solvent oil is used for each immersion. After the treatment, the asphalt concentration in the solvent oil is low, and it takes a long time to recover...
