[0027] The opening and closing device comprises a lifting plate 4, slide posts 5 are arranged on both sides of the lifting plate 4, slide grooves 6 are arranged on both sides of the partition plate 3, the slide posts 5 are slidably arranged in the slide grooves 6, and the lifting plate 4 is driven to rise and fall by a cylinder 7;

[0028] A support frame 8 is provided at the upper end of the slide 6, and the cylinder 7 is fixedly installed on the support frame 8. A fixed column 9 is provided at the middle of the upper end of the lifting plate 4, and a fixed plate 10 is provided at the upper end of the fixed column 9. The fixed plate 10 is connected to the output end of the cylinder 7;

[0029] A sealing strip 11 is provided at the bottom of the lifting plate 4, and a sealing sheet 12 is provided outside the sliding column 5;

[0030] A water outlet 24 and an oil outlet 25 are respectively provided on one side of the silent pool 1 and the oil collecting pool 2 near the bottom.

[0031] Among them, the opening and closing device is used to control the outflow and closing of the lubricating oil. When working, the waste liquid is first transported to the silent pool 1 for silencing. Due to the different densities of the lubricating oil and water, the lubricating oil will float on the water after silencing, and then the cylinder 7 is started. The cylinder 7 drives the lifting plate 4 to intermittently descend through the fixed column 9, so that the lubricating oil floating above the silent pool 1 flows into the oil collecting pool 2 through the upper end of the lifting plate 4 to separate the lubricating oil. When the floating lubricating oil is about to be separated, the lifting plate 4 is driven to rise by the cylinder 7 to prevent the water at the bottom of the lubricating oil from flowing into the oil collecting pool 2. At this time, water and a small amount of lubricating oil on the top of the water are left in the silent pool 1. Then the drain port 24 of the silent pool 1 is opened to discharge the water in the silent pool 1, and leave the remaining small amount of lubricating oil in the silent pool 1, and then continue to discharge into the wastewater for silencing to separate the lubricating oil for the next cycle.

[0032] A liquid inlet pipe 13 is provided on one side of the silent pool 1, and the liquid inlet pipe 13 is connected to a solid filtering device;

[0033] The solid filtering device includes a filter box 14, a first filter 15 is provided inside the filter box 14, a dirt collecting tank 16 is provided on one side of the first filter 15, and the dirt collecting tank 16 is located at the bottom of the filter box 15, a sewage pipe 17 is provided at the bottom of the sewage collecting tank 16, an electric control valve 23 is provided at the connection between the sewage pipe 17 and the sewage collecting tank 16, and a sewage collecting box 18 is provided at the output end of the sewage pipe 17;

[0034] A flushing mechanism is provided on the other side of the first filter 15, and the flushing mechanism includes a flushing pump 19 and a flushing head 20. The flushing head 20 is connected to the flushing pump 19 through a flushing pipe 21, and the flushing head 20 sprays toward the first filter 15;

[0035] The flushing pump 19 is connected to the interior of the silent pool 1 through a pipeline, and a second filter 26 is provided at the water inlet of the pipeline;

[0036] A sealing cover 22 is disposed at the upper end of the filter box 14 for facilitating the removal of the first filter 14 , and a handle is disposed at the upper end of the sealing cover 22 .

[0037] The solid filter device is used to filter the particles in the waste liquid. The waste liquid generated by the spray is transported to the filter box 14 through the delivery pump. After being filtered by the first filter 15, the waste water flows into the silent pool 1 for silent treatment. The particles are blocked by the first filter 15 and deposited in the sewage collection tank 16. By opening the electric control valve 23, the particles can fall into the sewage collection box 18.

[0038] The impact mechanism is used to backwash the first filter 15 to prevent the first filter 15 from being blocked. The flushing pump 19 supplies water to the flushing head 20 so that the flushing head 20 can flush the first filter 15 .

[0039] The working principle and use process of this utility model:

[0040] The solid filtering device is used to filter particulate matter in the waste liquid. The waste liquid generated by the spray is transported to the filter box 14 through the delivery pump. After being filtered by the first filter 15, the waste water flows into the silent tank 1 for silent treatment, and the particulate matter is blocked by the first filter 15 and deposited in the sewage collection tank 16. By opening the electric control valve 23, the particulate matter can fall into the sewage collection tank 18; the impact mechanism is used to backwash the first filter 15 to prevent the first filter 15 from being blocked, and the flushing head 20 is supplied with water through the flushing pump 19 so that the flushing head 20 can flush the first filter 15; after the waste liquid enters the silent tank 1, the waste liquid is silent. Due to the different densities of lubricating oil and water, the lubricating oil will float on the surface after being silent. Above the water, the opening and closing device is used to control the outflow and closing of the lubricating oil, and the cylinder 7 is started. The cylinder 7 drives the lifting plate 4 to intermittently descend through the fixed column 9, so that the lubricating oil floating above the silent pool 1 flows into the oil collecting pool 2 through the upper end of the lifting plate 4 to separate the lubricating oil. When the floating lubricating oil is about to be separated, the lifting plate 4 is driven to rise by the cylinder 7 to prevent the water at the bottom of the lubricating oil from flowing into the oil collecting pool 2. At this time, water and a small amount of lubricating oil on the top of the water are left in the silent pool 1, and then the drain port 24 of the silent pool 1 is opened to discharge the water inside the silent pool 1, and leave the remaining small amount of lubricating oil in the silent pool 1, and then continue to discharge it into the wastewater for silencing, and separate the lubricating oil for the next cycle.
