Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Figure 1 It is a three-dimensional structure diagram of an oily sludge treatment device for crude oil exploitation provided by an embodiment of the present utility model, Figure 2 It is a side sectional structure diagram of an oily sludge treatment device for crude oil exploitation provided by an embodiment of the present utility model. As Figure 1 and Figure 2 shown, the device includes: an installation pipe 1, on the side wall of the installation pipe 1, a filter frame 28 is installed; at both ends of the installation pipe 1, a feeding groove 5 and a discharging groove 6 are respectively arranged; at one end of the installation pipe 1 close to the feeding groove 5, a motor 7 is arranged, the output shaft of the motor 7 is connected to an installation shaft 8, the installation shaft 8 penetrates through the inside of the installation pipe 1, and a spiral conveying frame 9 is arranged on the installation shaft 8; a cleaning device 11 is arranged outside the installation pipe 1, and a hopper turning frame 12 is arranged inside the feeding groove 5.

[0023] Specifically, the cleaning device 1 is used to clean the outer side wall of the filter frame 28;

[0024] The hopper turning rack 12 is used to turn the oily sludge material entering the feed chute 5 to prevent the material from blocking the feed chute 5.

[0025] Specifically, the motor 7 works to drive the spiral conveyor rack 9 to rotate, thereby moving the material from the feed chute 5 towards the discharge chute 6. Thus, the material is squeezed during transportation, and the oily sludge can be filtered. A cleaning device 11 for cleaning the filter rack 28 is installed outside the installation pipe 1, which can clean the filter rack 28 and ensure the filtering efficiency of the filter rack 28. A hopper turning rack 12 for preventing blockage is installed inside the feed chute 5, enabling the material to quickly enter the installation pipe 1.

[0026] Specifically, as Figure 2 shown, installation grooves 2 are provided on both sides of the installation pipe 1, and the filter rack 28 is detachably installed inside the installation grooves 2.

[0027] Specifically, as Figure 1 shown, the feed chute 5 is arranged above one end of the installation pipe 1, and the discharge chute 6 is arranged below the other end of the installation pipe 1.

[0028] Specifically, as Figure 1 and Figure 2 shown, the cleaning device 11 includes two first gears 17 arranged on both sides of the filter rack 28, a connecting shaft 19 arranged between the two first gears 17, and bristles 20 arranged on the connecting shaft 19. Preferably, the inside of the first gear 17 is installed outside the installation pipe 1 through a bearing.

[0029] Specifically, when the two first gears 17 rotate, they can drive the connecting shaft 19 to rotate, so that the bristles 20 can clean the outside of the filter rack 28. The bristles 20 and the filter rack 28 are in interference fit, so that the bristles 20 have a high probability of inserting into the mesh holes of the filter rack 28, facilitating pushing the sludge inside the mesh holes into the installation pipe 1.

[0030] Specifically, as Figure 1 and Figure 2 shown, one end of the installation shaft 8 penetrates to the outside of the installation pipe 1 and is connected to the first pulley 10. A support plate 13 is arranged above one end of the installation pipe 1 at the discharge chute 6. A rotating shaft 14 is rotatably installed inside the support plate 13. A second pulley 15 is arranged at one end of the rotating shaft 14. The second pulley 15 and the first pulley 10 are connected by a belt 16; a second gear 18 is arranged at the other end of the rotating shaft 14, and the first gear 17 and the second gear 18 are meshed and connected.

[0031] Specifically, when the installation shaft 8 rotates, the rotation of the first pulley 10, the second pulley 15 and the belt 16 can drive the rotation of the rotating shaft 14. Under the action of the second gear 18, the first gear 17 can be driven to rotate, thereby driving the brush bristles 20 to perform a circular motion along the installation pipe 1.

[0032] Specifically, as Figure 2 shown, the hopper tipping frame 12 includes a transmission shaft 21, a tipping plate 22 and a third gear 23. Among them, the transmission shaft 21 is arranged inside the feed chute 5, and the tipping plate 22 is arranged on the transmission shaft 21; the third gear 23 is arranged outside the feed chute 5 and is meshed and connected with the first gear 17; one end of the transmission shaft 21 penetrates the side wall of the feed chute 5 and is connected with the third gear 23.

[0033] Specifically, under the transmission of the first gear 17 and the third gear 23, the transmission shaft 21 can be driven to rotate, so that the tipping plate 22 can push the material into the interior of the installation pipe 1.

[0034] Figure 3 is a cross-sectional structural schematic diagram of an oily sludge treatment device for crude oil exploitation according to an embodiment of the present invention. Figure 4 is a partial enlarged view of the A1 end according to an embodiment of the present invention. As Figure 3 and Figure 4 shown, the filter rack 28 includes an upper filter screen 3 and a lower filter screen 4. A connecting plate 25 is installed on one side edge of the upper filter screen 3 and the lower filter screen 4. Through holes 26 are provided on the connecting plate 25, and bolts 27 are installed inside the through holes 26. The upper filter screen 3 and the lower filter screen 4 are connected through the connecting plate 25 and the bolts 27, so as to facilitate the installation and disassembly operations of the upper filter screen 3 and the lower filter screen 4.

[0035] Specifically, as Figure 4 shown, scraping plates 24 are arranged on the side surfaces of the connecting plates 25 on both sides of the lower filter screen 4 for scraping and washing the brush bristles 20, and can scrape off the oil adhered to the brush bristles 20, thereby realizing the cleaning operation of the brush bristles 20.

[0036] As can be seen from the above description, the embodiment of the present utility model provides an oily sludge treatment device for crude oil exploitation. By arranging a cleaning device outside the installation pipe, the filter rack on the installation pipe can be cleaned, which not only facilitates the rapid fall of the filtered oily sludge, but also can push the materials inside the mesh holes on the filter rack into the interior of the installation pipe, thereby preventing blockage. By arranging a hopper turning rack in the feed tank, the materials in the feed tank can be turned, enabling the materials to smoothly enter the interior of the installation pipe. The present utility model alleviates the technical problems existing in the prior art that when the oily sludge is extruded, some of the sludge will block the mesh holes of the filter screen, which will affect the extrusion efficiency, and at the feeding position, sometimes the oily sludge cannot smoothly enter the interior of the treatment device.
