As shown in fig. 10, the solid-liquid separator includes an auger 13 disposed obliquely, the auger 13 has an outer shell 131 disposed obliquely upward and an auger shaft 132 disposed in the outer shell 131, a flange ring 133 rotatably fitted with the auger shaft 132 is disposed at a lower end of the outer shell 131, a bearing block 134 is fixedly disposed at an outer side of a bottom end of the outer shell 131, the auger shaft 132 is rotatably disposed in the bearing block 134 through a bearing 1341, a drainage cavity 135 is disposed at a side of the bearing block 134 adjacent to the flange ring 133, the drainage cavity 135 includes a drainage cavity 1352 adjacent to a side of the flange ring 133 and a separation cavity 1351 for separating the drainage cavity 1352 from the bearing 1341, a caliber of the drainage cavity 1352 is larger than a caliber of the separation cavity 1351, so that a step is formed between the separation cavity 1351 and the drainage cavity 1352, specifically, the drainage cavity 1352 covers a region of the separation cavity 1351, for example, the drainage cavity 1352 is a circular cavity with a large caliber, the separation cavity 1351 is a circular cavity with a small caliber, a drainage tube 136 is disposed at a bottom of the drainage cavity 1352 and a water outlet pipe 251 of the liquid pump 25 is communicated with an upper end of the drainage cavity 1352.
Because a gap exists between the flange ring 133 and the auger shaft 132, the oil-water mixture in the auger 13 can be immersed into the bearing seat 134 through the gap, and then the bearing 1341 is polluted, and in order to prevent the oil-water mixture from polluting the bearing 1341, the invention has the function of protecting the bearing 1341 by arranging a separation cavity 1351 with a smaller caliber than the drainage cavity 1352 between the drainage cavity 1352 and the bearing 1341, so that the mixture immersed into the bearing seat 134 from the gap can flow to the drainage cavity 1352 and be discharged from the drainage tube 136 at the bottom of the drainage cavity 1352.
The clean water is injected into the drainage cavity 135 through the liquid pump 25, the introduced clean water cleans the drainage cavity 135, and finally the clean water is discharged through the drainage tube 136 at the bottom of the liquid discharging cavity 1352, so that the cleaning effect is achieved.
The foregoing examples merely illustrate one or more embodiments of the invention, which are described in greater detail and are not to be construed as limiting the scope of the invention. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the invention, which are all within the scope of the invention. Accordingly, the scope of the invention should be assessed as that of the appended claims.
