[0002] Wastewater oil sludge is a substance mixed in with wastewater. It mainly comes from oily wastewater, such as wastewater generated in the petrochemical, machinery processing and food processing industries. This wastewater contains a large amount of oil. When this oily wastewater enters the treatment system, the oil mixes with solid impurities and microbial metabolites in the water. After physical, chemical or biological treatment processes, some of the oil aggregates to form oil droplets, which then settle or float on the surface of the wastewater along with other suspended solids, eventually forming wastewater oil sludge.

It integrates multiple pretreatment functions and can systematically perform preliminary treatment on wastewater containing oil sludge. In the past, the pretreatment of wastewater oil sludge and sand was completed by multiple separate devices, which was cumbersome and occupied a lot of space. The current wastewater oil sludge and sand pretreatment device integrates multiple pretreatment functions into one device, thereby reducing the size of the equipment. However, the existing integrated pretreatment devices rely on manual dredging to deal with floating oil sludge, which not only consumes a lot of manpower but also has poor treatment effect. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an integrated pretreatment device, which aims to improve the existing integrated pretreatment device for treating floating oil slicks by manual retrieval, which not only consumes a lot of manpower but also leads to poor treatment results.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 3 and Figure 4This utility model provides an embodiment of an integrated pretreatment device, comprising a body 1. A motor 3 is fixedly connected to the rear end of the top left side of the body 1. A drive sprocket 4 is fixedly connected to the output end of the motor 3, which drives the drive sprocket 4 to rotate. Two power rods 5 are equidistantly rotatably connected inside the left side of the body 1. A driven sprocket 6 is fixedly connected to the rear side of the left power rod 5. The drive sprocket 4 is connected to the driven sprocket 6 via a drive chain 7, and the drive sprocket 4 drives the driven sprocket 6 to rotate via the drive chain 7. Traction sprockets 8 are fixedly connected to the front and rear ends of the left power rod 5, and the driven sprocket 6 drives the traction sprockets 8 to rotate via the power rod 5. Traction sprockets 9 are fixedly connected to the front and rear ends of the right power rod 5, and the two traction sprockets 8 are respectively connected to the corresponding traction sprockets via corresponding traction chains 10. The transmission connection is 29. The traction sprocket 18 drives the traction sprocket 29 to rotate through the traction chain 10. Two scraper plates 11 are fixedly connected at equal intervals on the outer sides of the two traction chains 10. The traction chain 10 drives the scraper plates 11 to rotate. A slag conveying trough 12 is opened on the left side of the inside of the machine body 1. A horizontal spiral cleaning mechanism 2 is installed at the bottom of the machine body 1. The horizontal spiral cleaning mechanism 2 is used to clean the settled oil sludge and sand. An aeration blower 15 is fixedly connected to the rear side of the middle of the top wall of the machine body 1. The output end of the aeration blower 15 is connected to the inclined spiral conveyor 16 and sealed. The aeration blower 15 blows a certain pressure of air into the aeration pipe in the machine body 1 through a special pipe to separate the oil sludge and sand in the sewage. The gas is blown into the machine body 1. An oil sludge outlet 19 is connected to the left side of the front side of the machine body 1. The oil sludge outlet 19 is used to discharge the oil sludge in the slag conveying trough 12.

[0032] Specifically, when sewage flows into the machine body 1, the motor 3 provides power to drive the drive sprocket 4 to rotate. When the drive sprocket 4 rotates, it drives the driven sprocket 6 fixed to the rear end of the left power rod 5 to rotate synchronously through the drive chain 7. When the driven sprocket 6 rotates, it drives the left power rod 5 to rotate synchronously. As the left power rod 5 rotates, the two traction sprockets 8 fixed on it will also rotate synchronously. When the two traction sprockets 8 rotate, they will drive the corresponding traction sprockets 9 fixed on the right power rod 5 to rotate synchronously through the corresponding traction chain 10. When the two traction chains 10 rotate, the scraper 11 fixed on them will also rotate, thereby scraping the grease and fine sludge floating on the sewage into the sludge conveying tank 12. The aeration blower 15 blows a certain pressure of air into the aeration pipe in the machine body 1 through a special pipe to separate the sewage from the oil, sludge and sand. The gas is blown into the machine body 1 to accelerate the separation speed of oil, sludge and sand and sewage. The oil sludge scraped into the sludge conveying tank 12 can be discharged through the oil sludge outlet 19 connected to the machine body 1.

[0033] Reference Figure 2 and Figure 5The horizontal spiral cleaning mechanism 2 includes a U-shaped tube 201. The top of the U-shaped tube 201 is fixedly connected to the bottom of the machine body 1. A fixing block 203 is fixedly connected to the right side of the U-shaped tube 201. A motor 202 is fixedly connected to the right side of the fixing block 203. The fixing block 203 is used to fix the motor 202. A rotating rod 204 is fixedly connected to the output end of the motor 202. A spiral blade 205 is fixedly connected to the outer wall of the rotating rod 204. The motor 202 drives the spiral blade 205 to rotate through the rotating rod 204. A sealing ring 206 is fixedly connected to the outer wall of the fixing block 203. The sealing ring 206 is used to enhance the sealing between the fixing block 203 and the U-shaped tube 201. A slag remover 14 is fixedly connected to the top right side of the machine body 1. A screw conveyor 13 is connected to the front side of the slag remover 14. The screw conveyor 13 can discharge the waste slag in the slag remover 14.

[0034] Specifically, the motor 202, which is fixed to the right side of the U-shaped tube 201 by the fixing block 203, is started. The power provided by the motor 202 drives the rotating rod 204 to rotate. As the rotating rod 204 rotates, the spiral blade 205 fixed on it will also be driven to rotate synchronously. When the rotating rod 204 drives the spiral blade 205 to rotate in the U-shaped tube 201, it will push the large particles of oil sludge and sand deposited in the U-shaped tube 201 to the right, and concentrate the oil sludge and sand on the right side of the U-shaped tube 201 for later cleaning. The sealing ring 206 can further seal the fixing block 203 and the U-shaped tube 201. The inclined spiral conveyor 16, which runs through to the bottom, will collectively spirally transport the oil sludge and sand deposited on the right side from bottom to top to the top side of the pipe for discharge.

[0035] Reference Figure 1 and Figure 2 A cover plate 17 is slidably connected to the top left end of the body 1. A handle 18 is fixedly connected to the top of the cover plate 17. The handle 18 is used to lift the cover plate 17. Multiple support legs 20 are fixedly connected at equal intervals on the front and rear sides of the body 1. A stabilizing rod 21 is fixedly connected to each adjacent side of the multiple support legs 20. The support legs 20 cooperate with the stabilizing rod 21 to support the body 1. A connecting rod 22 is fixedly connected to the bottom of the multiple support legs 20. A protective pad 23 is fixedly connected to the bottom of the multiple connecting rods 22. The protective pad 23 provides protection for the bottom of the support legs 20.

[0036] Specifically, the support leg 20 is used to support the body 1, the stabilizer bar 21 is used to improve the stability of the support leg 20, and the protective pad 23 fixed under the support leg 20 by the connecting rod 22 can provide protection for its bottom.

[0037] Working principle: When sewage flows into the machine body 1, the motor 3 provides power to drive the drive sprocket 4 to rotate. When the drive sprocket 4 rotates, it drives the driven sprocket 6 fixed at the rear end of the left power rod 5 to rotate synchronously through the drive chain 7. When the driven sprocket 6 rotates, it drives the left power rod 5 to rotate synchronously. As the left power rod 5 rotates, the two traction sprockets 8 fixed on it will also rotate synchronously. When the two traction sprockets 8 rotate, they will drive the corresponding traction sprockets 9 fixed on the right power rod 5 to rotate synchronously through the corresponding traction chain 10. When the two traction chains 10 rotate, the scraper 11 fixed on them will also rotate, thereby scraping the grease and fine sludge floating on the sewage into the sludge conveying tank 12. This achieves the effect of cleaning the grease and fine sludge on the surface of the sewage, thereby saving labor costs and improving work efficiency.

[0038] After the wastewater in the integrated pretreatment device is discharged, the motor 202, which is fixed to the right side of the U-shaped pipe 201 by the fixing block 203, is started. The power provided by the motor 202 drives the rotating rod 204 to rotate. As the rotating rod 204 rotates, the spiral blade 205 fixed on it will also be driven to rotate synchronously. When the rotating rod 204 drives the spiral blade 205 to rotate in the U-shaped pipe 201, it will push the large oil sludge and sand particles settled in the U-shaped pipe 201 to the right, and concentrate the oil sludge and sand on the right side of the U-shaped pipe 201 for later cleaning. The sealing ring 206 can further seal the fixing block 203 and the U-shaped pipe 201, thereby achieving the effect of concentrating the large oil sludge and sand particles. The inclined spiral conveyor 16 that runs through to the bottom will collectively spirally transport the oil sludge and sand deposited on the right side from bottom to top to the top side pipe and discharge it outside the equipment.
