It is based on clay and water, with many oxygen anions, sulfonate ions, carboxylate groups, etc. It is a negative ion system under alkaline conditions, that is, clay is dispersed in water to form a relatively stable dispersion system and cannot sink in water for a long time. Drilling waste liquid contains various salts and heavy metal elements, which are highly toxic to organisms. Drilling waste liquid needs to be purified, but there are a large number of cuttings in the drilling waste liquid, and these cuttings need to be filtered before the treatment and purification of the drilling fluid.

[0024] As Figures 1-5 shown, a drilling waste liquid and cuttings separation device includes a support rod 2, and also includes a separation tank 1 and a mixing mechanism 3. The separation tank 1 is fixedly connected to the upper ends of several support rods 2. An upper end of one side of the separation tank 1 is fixedly connected and communicated with a liquid inlet pipe 101, and a third flange 102 is fixedly connected to the liquid inlet pipe 101, so as to facilitate the input of drilling waste liquid through the connecting pipe 107. A lower end of one side of the separation tank 1 is fixedly connected and communicated with a liquid outlet pipe 104. A control valve 106 is connected in the liquid inlet pipe 101. An upper end of the separation tank 1 is fixedly connected and communicated with a feed pipe 103. A chip outlet 110 is provided at the lower end of the separation tank 1. A sealing cover 4 is threadedly connected to the lower end of the separation tank 1 at the chip outlet 110. A sealing block 401 is fixedly connected to the sealing cover 4, and the sealing block 401 is inserted and adapted to the chip outlet 110. The upper end of the sealing block 401 is flush with the inner wall of the separation tank 1. A handle 402 is fixedly connected to the lower end of the sealing cover 4. The mixing mechanism 3 is connected inside the separation tank 1, and the mixing mechanism 3 is used to promote the mixing of the flocculant and the waste liquid.

[0025] As Figure 3 、 5 shown, in order to promote the mixing of the flocculant and the drilling waste liquid, the mixing mechanism 3 includes a motor 301, a mixing plate 303 and a scraper 304. The motor 301 is fixedly connected to the upper end of the separation tank 1. An output end of the motor 301 is fixedly connected to a connecting shaft 302. The connecting shaft 302 is rotatably connected in the separation tank 1. Several mixing plates 303 are fixedly connected to the outer periphery of the connecting shaft 302, and several scrapers 304 are fixedly connected to the outer periphery of the connecting shaft 302.

[0026] As Figure 3 、 5 shown, the scraper 304 is inclined, an inclined plane 305 is provided at the lower end of the scraper 304, and the lower end of the scraper 304 is slidably attached to the bottom end of the inner wall of the separation tank 1, so as to facilitate the discharge of the separated solid matter from the chip outlet 110. The end of the scraper 304 is arc-shaped, and the end of the scraper 304 is slidably attached to the inner side wall of the separation tank 1.

[0027] As Figure 4As shown, in order to avoid the discharge of solid substances when collecting liquid substances after separation, a connecting pipe 107 is connected to the liquid outlet pipe 104. The liquid outlet pipe 104 is fixedly connected with a first flange 105, and the connecting pipe 107 is fixedly connected with a second flange 108. A bolt 109 is passed through the second flange 108. The first flange 105 and the second flange 108 are connected by the bolt 109. Sealing rings 502 are fixedly connected to the inner sides of the first flange 105 and the second flange 108.

[0028] When the utility model is in use, the drilling waste liquid is introduced into the separation tank 1 through the liquid inlet pipe 101, and a flocculant is introduced into the separation tank 1 through the feed pipe 103. The output end of the motor 301 drives the connecting shaft 302 to rotate, thereby driving the mixing plate 303 and the scraping plate 304 to rotate, so as to promote the mixing of the flocculant and the drilling waste liquid. Through the action of the flocculant, the solid substances in the waste liquid are aggregated and settled at the bottom of the separation tank 1 to realize the separation of solid and liquid. The liquid outlet pipe 104 is controlled to be opened through the control valve 106, and then the liquid is collected through the connecting pipe 107. At the same time, the filter plate 5 is used to prevent solid substances from entering the connecting pipe 107 along with the liquid and being discharged. After the liquid collection is completed, the liquid outlet pipe 104 is closed, and the handle 402 is rotated to open the sealing cover 4, so that the sealing block 401 is separated from the chip outlet 110, and then the solid substances are collected through the chip outlet 110. Driven by the motor 301, the scraping plate 304 is attached to the lower end of the inner wall of the separation tank 1 to promote the discharge of the solid substances from the chip outlet 110 and be collected from the separation tank 1.

[0029] In summary: In the embodiment of the utility model, the flocculant is mixed with the drilling waste liquid to realize the sedimentation separation of the drilling waste liquid. The separation effect is good and the separation efficiency is high. The mixing mechanism 3 can promote the mixing of the flocculant and the drilling waste liquid, further improving the separation efficiency. When the scraping plate 304 rotates in the separation mechanism, it can stir and mix the flocculant and the drilling waste liquid. After the liquid separated in the separation tank 1 is discharged after separation, the scraping plate 304 can be used to promote the discharge of the solid substances from the chip outlet 110.
