DETAILED DESCRIPTION
[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.
[0024] Please refer to Figures 1-4 The utility model provides a technical scheme: an oily waste liquid separation device, which comprises a separation tank 1, a partition 2, a boss 3, a filter screen 4, a roller shaft 5, a motor 6, a conveying belt 7, a scraper 8, an adjusting wheel 9, a water inlet 10, an oil outlet 11, a sewage outlet 12, a water outlet 13, a rotating shaft 14, a cleaning blade 15, a handle 16, a baffle 17 and a locking rod 18.
[0025] The separation tank 1 is provided with the partition 2 on the right side inner wall, the boss 3 is arranged on the left side bottom of the separation tank 1, the filter screen 4 is installed on the boss 3, the roller shaft 5 is arranged on the top of the separation tank 1, the conveying belt 7 is arranged on the outside of the roller shaft 5, the scraper 8 is connected to the outside of the conveying belt 7, the motor 6 is connected to the rear end of the roller shaft 5, the motor 6 is fixedly connected to the separation tank 1, the water inlet 10 and the oil outlet 11 are arranged on the left and right sides of the bottom of the separation tank 1, the sewage outlet 12 is arranged on the bottom end of the separation tank 1, the water outlet 13 is arranged on the front side of the middle part of the separation tank 1, the rotating shaft 14 is arranged below the filter screen 4, the cleaning blade 15 is arranged on the outside of the rotating shaft 14, and the handle 16 is connected to the left end of the rotating shaft 14 and penetrates through the left side of the separation tank 1.
[0026] The baffle 17 is arranged on the top right side of the partition 2, and the locking rod 18 is arranged on the top right end of the partition 2.
[0027] As Figure 1 , Figure 2 and Figure 3The top of the partition 2 is lower than the top of the separator 1, and the baffle 17 and the partition 2 form a sliding structure to facilitate oil discharge. There are two rollers 5 on the top left and right of the separator 1, and the diameter of the left roller 5 is larger than that of the right roller 5 to facilitate the use of the scraper 8. An adjusting wheel 9 is provided on the left side of the right roller 5, and there are two adjusting wheels 9 on the left and right sides respectively. The conveyor belt 7 is set in an "S" shape at the adjusting wheel 9 to facilitate the upward movement of the scraper 8.
[0028] like Figure 1 , Figure 3 and Figure 4 Scrapers 8 are evenly spaced on the outer side of the middle conveyor belt 7 to increase the oil discharge efficiency. The cleaning blade 15 has a spiral blade structure, and the bottom of the cleaning blade 15 fits into the bottom of the separation box 1 to facilitate the discharge of mud and sand in the separation box 1. The bottom of the baffle 17 is provided with a sliding groove, and the locking rod 18 passes through the sliding groove in the baffle 17 and is threadedly connected to the partition 2 to facilitate the adjustment of the height of the baffle 17.
[0029] Working principle: When using this oily waste liquid separation device, if... Figure 1 As shown, waste liquid is added into separation tank 1 through inlet 10. As the waste liquid rises in separation tank 1, it is filtered through filter screen 4, causing sediment to settle to the bottom of separation tank 1, while oil floats to the surface through filter screen 4. During the rising process, wastewater in the waste liquid is discharged through drain outlet 13. Starting motor 6 causes roller 5 to rotate, which in turn causes conveyor belt 7 to drive scraper 8 to scrape the floating oil. The oil is then discharged through baffle 17 above partition 2 to the right side of separation tank 1 and discharged through oil outlet 11. Figure 2 As shown, when the conveyor belt 7 drives the scraper 8 to move, the conveyor belt 7 drives the scraper 8 to move upward through the action of the adjusting wheel 9, so as to avoid the scraper 8 from contacting and colliding with the baffle 17, and to facilitate the use of the scraper 8. According to the oil content in the waste liquid, the height of the top position of the baffle 17 can be adjusted by sliding the baffle 17, and then the locking rod 18 can be rotated to clamp and fix the baffle 17 on the partition 2.
[0030] After the silt accumulates at the bottom of separation tank 1 for a period of time, as... Figure 1 As shown, by rotating the handle 16, the rotating shaft 14 is driven to rotate, which in turn drives the cleaning blade 15 to rotate. The spiral blade structure of the cleaning blade 15 is used to discharge the mud and sand from the sewage outlet 12. This is the entire working process of the oily waste liquid separation device. The contents not described in detail in this specification are existing technologies known to those skilled in the art.
