[0035] The primary purification component 3 includes a filter 301, a filter ring 302, a slag discharge pipe 305, a buffer filter bag 306, a connecting rod 308 and a sealing plug 309. The outside of the filter 301 is fixedly connected to the inside of the fixed tank body 1. The filter ring 302 is inclined toward one side of the slag discharge pipe 305 and is installed in the middle of the filter 301. The filter ring 302 divides the filter 301 into a filter chamber 307 and a guide chamber 303. The bottom annular array of the guide chamber 303 is provided with a connecting hole 304. The buffer filter bag 306 is arranged at the top of the filter 301. The connecting rod 308 penetrates and is fixedly connected to the buffer filter bag 306.

[0036] The driving assembly 4 includes a motor 401, a screw 402, a movable ring 403, a gear 405, a steel wire rope 406 and a rotating rod 407. The motor 401 is installed on the top of the fixed tank body 1. One end of the screw 402 penetrates the fixed tank body 1 and is fixedly connected to the output end of the motor 401. The movable ring 403 is threadedly connected to the screw 402. A plurality of racks 404 are arranged in an annular array on the bottom side of the movable ring 403. The bottom end of the rack 404 is meshed with a gear 405. The middle part of the gear 405 is fixedly connected with a rotating rod 407. Both ends of the rotating rod 407 are wound with steel wire ropes 406.

[0037] The secondary purification component 5 includes an oil filter 501, a sponge ball 502, a pull ring 504 and a partition 505. The top of the oil filter 501 is fixedly connected to the filter 301, the upper and lower ends of the oil filter 501 are fixedly connected to the partition 505, the sponge ball 502 is filled between the oil filter 501 and the partition 505, the pull ring 504 is fixedly connected to the outer peripheral surface of the bottom end of the oil filter 501, and the top side of the pull ring 504 is fixedly connected to the wire rope 406.

[0038] The sewage is transported downward through the water inlet component 2, and a part of the sand and gravel is filtered by the buffer filter bag 306. With the increase of sand and gravel and the increase of water volume, the sewage overflows from the top of the buffer filter bag 306, and the sand and gravel can slide downward along the filter 301 to the filter ring 302 due to the impact of the water flow. The water after the primary purification is collected on the top side of the sealing plug 309, and the screw 402 is driven to rotate by the motor 401, so that the movable ring 403 drives the connecting plate 204 to move upward, thereby compressing the bellows 202 and the spring 203. The connecting plate 204 drives the connecting rod 308 and the sealing plug 309 to move upward through the drainage pipe 205, and the water can enter the oil filter 501 and filter the engine oil contained in the sewage through the sponge ball 502, so that the water after the secondary purification is discharged from the drain pipe 503, so that the filtering effect of the device is good.

[0039] like Figures 2 to 4 , Figure 7As shown, the middle part of the slag discharge pipe 305 passes through the fixed tank body 1 and one end is fixedly connected to the filter 301. The filter 301 is a shuttle-shaped structure with narrow upper and lower ends and a wide middle part. A conical filter plate with a narrow upper part and a wide lower part is arranged inside the filter 301. The bottom of the conical filter plate is fixedly connected to the inner ring of the filter ring 302. The buffer filter bag 306 is made of a flexible filter bag. The bottom of the drainage pipe 205 is located directly above the buffer filter bag 306. The sealing plug 309 is sealed and connected to the bottom of the filter 301. The outer end of the water inlet pipe 201 is sleeved with a spring 203. The two ends of the spring 203 are respectively fixedly connected to the fixed tank body 1 and the connecting plate 204. The bottom of the drainage pipe 205 is a funnel-shaped structure, and the drainage pipe 205 is located inside the top of the filter 301.

[0040] The bellows 202 allows the sewage to be continuously transported when the drainage tube 205 moves upward; the elastic force of the spring 203 allows the connecting plate 204 to abut against the movable ring 403. When the movable ring 403 moves downward, the connecting plate 204 moves downward synchronously. When the connecting plate 204 moves to the filter 301, it can be abutted by the filter 301, while the movable ring 403 can continue to move downward. The spring 203 can limit the connecting plate 204 and the drainage tube 205. When the sewage passes through the drainage tube 20 When the sewage is transported to the buffer filter bag 306, the flexible structure of the buffer filter bag 306 that can be concave inward can effectively prevent the sewage from splashing due to hard contact with the device. The connecting rod 308 is driven upward by the drainage pipe 205, and the connecting rod 308 can drive the bottom of the buffer filter bag 306 to move upward, so that the buffer filter bag 306 forms a conical structure, so that the filter residue collected by the buffer filter bag 306 can be poured out, and the filter residue can roll down along the conical filter plate and the filter ring 302 and be discharged through the residue discharge pipe 305, so that the device is easy to discharge solid filter residue.

[0041] like Figure 2 , Figures 4 to 6 As shown, the outer side of the rotating rod 407 is rotatably connected with the supporting rod 408, one end of the supporting rod 408 is fixedly connected to the outer side of the filter 301, the outer side of the movable ring 403 is slidably connected to the fixed tank body 1 in an upper and lower limit position, and the outer edge of the connecting plate 204 is movably connected to the movable ring 403;

[0042] The motor 401 drives the screw 402 to rotate, so that the movable ring 403 drives the connecting plate 204 to move upward, and the rack 404 is not meshed with the gear 405, so that the bellows 202 and the spring 203 are compressed, and the connecting plate 204 drives the connecting rod 308 and the sealing plug 309 to move upward through the drainage pipe 205. The connecting rod 308 can drive the bottom of the buffer filter bag 306 to move upward, so that the sealing plug 309 is not sealed with the filter 301, and the water can flow downward for secondary purification;

[0043] The motor 401 drives the screw rod 402 to rotate in the opposite direction, so that the movable ring 403 drives the rack 404 to move downward, and the rack 404 rotates in meshing with the gear 405, so that the rotating rod 407 can rotate to reel in the wire rope 406, and the supporting rod 408 can support and limit the rotating rod 407.

[0044] like Figure 2 , Figure 4 and Figure 5 As shown, the oil filter 501 is an oblate structure composed of an internal flexible membrane and an external annular array of folded frames, the sponge ball 502 is made of modified polyurethane sponge, the middle of the pull ring 504 is fixedly connected with a drain pipe 503, and the bottom of the fixed tank 1 is slidably connected to the pull ring 504 in an upper and lower limit position;

[0045] The sponge ball 502 can be limited by two partitions 505 and the oil filter 501. The modified polyurethane sponge has super hydrophobicity and super oleophilicity, and is particularly suitable for the removal and recovery of oil spills and organic solvents on water. The oil absorption capacity of this sponge is very good, and it can even absorb 90 times its own weight of oil. When water flows from top to bottom, the oil contained in it can be absorbed by the sponge ball 502;

[0046] When the pull ring 504 moves upward to physically squeeze the oil filter 501, most of the oil absorbed in the sponge can be squeezed out, so that the oil can be recycled and reused, and the sponge ball 502 can be used multiple times.

[0047] The working principle and use process of the present invention:

[0048] First, sewage enters the fixed tank 1 through the water inlet assembly 2, and a part of the sand and gravel is filtered by the buffer filter bag 306. As the amount of sand and gravel increases and the amount of water increases, sewage overflows from the top of the buffer filter bag 306, and the sand and gravel can slide down to the filter ring 302 along the conical filter plate under the impact of the water flow. The water after primary purification passes through the buffer filter bag 306, the conical filter plate and the filter ring 302 and is collected on the top side of the sealing plug 309. The motor 401 drives the screw 402 to rotate, so that the movable ring 403 drives the connecting plate 204 to move upward, thereby compressing the bellows 202 and the spring 203. The connecting plate 204 drives the connecting rod 308 and the sealing plug 309 to move upward through the drainage pipe 205. The water can enter the oil filter 501 and filter the oil contained in the sewage through the sponge ball 502, so that the water after secondary purification is discharged from the drain pipe 503;

[0049] The connecting rod 308 is driven upward by the drainage pipe 205, and the connecting rod 308 can drive the bottom of the buffer filter bag 306 to move upward, so that the buffer filter bag 306 forms a tapered structure that is narrow at the top and wide at the bottom, so that the filter residue collected by the buffer filter bag 306 can be poured out, and the filter residue can roll down along the conical filter plate and the filter ring 302 and be discharged through the residue discharge pipe 305;

[0050] The motor 401 drives the screw 402 to rotate in the opposite direction, the movable ring 403 moves downward, and the connecting plate 204 abuts against the movable ring 403 through the elastic force of the spring 203, so that the connecting plate 204 moves downward synchronously. When the connecting plate 204 moves to the filter 301, it can be abutted by the filter 301, and the movable ring 403 can continue to move downward, so that the movable ring 403 drives the rack 404 to move downward, and the rack 404 meshes and rotates with the gear 405, so that the rotating rod 407 can rotate to reel in the wire rope 406, and can pull the pull ring 504 to move upward, so that the oil filter 501 is squeezed and deformed, so that the engine oil adsorbed in the sponge ball 502 can be squeezed out to complete the operation.
