[0002] Oil refining produces oil sludge, which is classified as hazardous waste by the state and cannot be disposed of arbitrarily. It requires specialized harmless treatment, which costs many oil refining companies a considerable amount of money. In recent years, the pyrolysis process for oil sludge has become very popular as a method for harmless treatment. A set of equipment costs anywhere from hundreds of thousands to millions of yuan. Compared with other processes, it is simple, has a large processing capacity, and allows for the recovery of oil resources. The treated sludge meets national standards, and the investment is much smaller than that of other processes.

[0003] The present invention, CN216604333U, discloses a debris screening device for pyrolysis of oil sludge, comprising an upper shell, a screen provided on the inner wall of the upper shell, an mounting plate fixedly installed on the outer surface of the upper shell near the top edge, an oil pump fixedly installed on the top of the mounting plate, and a connecting pipe fixedly connected to the output end of the oil pump.

[0004] While the above solution offers many advantages, it also has the following drawbacks: the filter's filtration efficiency will decrease after prolonged use, usually requiring disassembly, cleaning, and replacement. However, the filter in this device is fixed inside the housing, making it cumbersome to remove and replace, resulting in less than ideal performance. Utility Model Content

[0005] The purpose of this invention is to provide a sieving device for oil sludge pyrolysis, which solves the problem that the filter screen in the prior art will reduce the filtration effect after long-term use, and usually requires people to disassemble, clean and replace it. However, the filter screen of this device is fixed inside the housing, which is troublesome to remove and replace, and the effect of use is not very good.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a sieving device for oil sludge pyrolysis, comprising a sieving tank, a valved discharge pipe fixedly installed at the bottom of the sieving tank, a sieving structure inside the sieving tank, the sieving structure comprising a square rod, the square rod being rotatably installed at the bottom inner side of the sieving tank, a sliding column being provided on the outer side of the square rod, a first filter screen plate and a second filter screen plate being provided on the outer side of the sliding column, two sliders being fixedly installed on the inner side of each of the first and second filter screen plates, and four elongated grooves being opened on the outer side of the sliding column, the four elongated grooves being adaptively matched with the four sliders respectively.

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.

[0025] Example: Figure 1 - Figure 7 As shown, this utility model provides a technical solution for a sludge pyrolysis debris screening device, including a screening tank 1. A valved discharge pipe 2 is fixedly installed at the bottom of the screening tank 1. A screening structure is provided inside the screening tank 1. The screening structure includes a square rod 7, which is rotatably installed on the inner bottom of the screening tank 1. A sliding column 8 is provided on the outer side of the square rod 7. A first filter screen 9 and a second filter screen 10 are provided on the outer side of the sliding column 8. Two sliders 11 are fixedly installed on the inner side of both the first filter screen 9 and the second filter screen 10. Four elongated grooves are opened on the outer side of the sliding column 8, and the four elongated grooves are adapted to match the four sliders 11 respectively.

[0026] An annular plate 12 is slidably mounted on the outer side of the sliding column 8. Four abutment plates 121 are fixedly installed on the inner side of the annular plate 12. The four abutment plates 121 are designed with two long and two short lengths. The four abutment plates 121 are respectively matched with the size of four long strip-shaped sliding grooves. Positioning plates 13 are fixedly installed on the bottom of two abutment plates 121. The inner side of the two positioning plates 13 is threaded with wing bolts 14. Threaded slots are opened in two of the long strip-shaped sliding grooves of the sliding column 8. The two wing bolts 14 are respectively threaded and matched with the two threaded slots.

[0027] A square groove is provided at the bottom of the sliding column 8. A square rod 7 is set inside the square groove and slides in contact with the sliding column 8. A No. 1 motor 15 is fixedly installed at the bottom of the screening tank 1. The output end of the No. 1 motor 15 passes through the bottom of the screening tank 1 and is fixedly connected to the square rod 7.

[0028] A placement plate 3 is fixedly installed on the outside of the screening tank 1. A mud pump 4 is fixedly installed on the top of the placement plate 3. A mud pump pipe 5 is fixedly installed on one end of the mud pump 4. The other end of the mud pump 4 is connected to the inside of the screening tank 1. A water inlet pipe 6 is fixedly connected to the outside of the screening tank 1.

[0029] Four fixed seats 16 are fixedly installed on the outside of the screening tank 1. The four fixed seats 16 are in pairs, and screws 17 are rotatably installed between the two pairs of fixed seats 16. Moving plates 18 are threadedly connected to the outside of the two screws 17.

[0030] Two connecting plates 19 are fixedly installed on the top of each of the two movable plates 18. The top of each of the four connecting plates 19 passes through two of the fixed seats 16 and slides in contact with each of the two fixed seats 16. A top plate 20 is fixedly installed on the top of the four connecting plates 19. A connecting column 21 is rotatably installed on the bottom of the top plate 20. The sliding column 8 and the connecting column 21 are fixedly connected.

[0031] The bottom of the other two fixed bases 16 are each fixedly installed with a second motor 22. The output ends of the two second motors 22 pass through the other two fixed bases 16 and are respectively fixedly connected to the two screws 17.

[0032] It should be noted that this utility model is a sieving device for oil sludge pyrolysis. When in use, start motor 15 (the specific model of motor 15 is not described, but is based on the compatible equipment). Motor 15 will drive the square rod 7 to rotate, which will drive the sliding column 8 on the outside of the square rod 7 to rotate, thereby driving the first filter plate 9 and the second filter plate 10 to rotate. Then start the sludge pump 4 and pump the oil sludge into the screening tank 1 through the sludge pumping pipe 5. The pumped oil sludge will fall onto the first filter plate 9 for preliminary screening. The oil sludge after preliminary screening will fall onto the top of the second filter plate 10 for a second screening. After screening, the oil sludge will fall into the bottom of the screening tank 1 and can be discharged through the valved discharge pipe 2.

[0033] After screening is completed, when it is necessary to clean the impurities on the top of the first filter plate 9 and the second filter plate 10, start the two No. 2 motors 22. The specific model of the No. 2 motors 22 is not described, but depends on the compatible equipment. The No. 2 motors 22 will drive the screw 17 to rotate, thereby driving the moving plate 18 to move upward, which in turn drives the two connecting plates 19 to move upward, thereby driving the top plate 20 to move upward, which in turn drives the sliding column 8 to move through the connecting column 21, thereby removing the first filter plate 9 and the second filter plate 10 from the inside of the screening tank 1. This makes it easier for people to clean the screened impurities. The operation is simple and improves the practicality of the device.

[0034] When the first filter plate 9 and the second filter plate 10 need to be replaced after a period of use, first start the two No. 2 motors 22 to move the first filter plate 9 and the second filter plate 10 out of the screening tank 1. Then, turn the two butterfly bolts 14 to remove the limiting effect on the two positioning plates 13. At this time, the annular plate 12 can slide out from the bottom of the sliding column 8, thereby releasing the limiting effect on the first filter plate 9 and the second filter plate 10. Thus, the first filter plate 9 and the second filter plate 10 can be slid out from the outside of the sliding column 8 for replacement. The disassembly and assembly are quick, which effectively improves the use effect of the device.
