Description

Technical Field

[0001] This utility model relates to the field of petroleum processing technology, specifically a residue re-separation and residual oil extraction device. Background Technology

[0002] Residual oil is a heavy residue remaining after multiple distillations and extraction of light fractions during the petroleum refining process. It is characterized by high viscosity and density, and its composition is complex, rich in macromolecular hydrocarbons, gums, asphaltenes, etc. It usually needs to be further processed or used as fuel or asphalt raw material. Under environmental protection requirements, the treatment and utilization of residual oil must take into account both energy efficiency and emission reduction, and it is one of the key by-products that need to be focused on in the petroleum industry.

[0003] During the extraction of residual oil, large pieces of residue are crushed by a crusher and filtered with a screen to remove large particles of impurities. For raw materials containing a lot of mud, sand, and dust, they are washed with hot water or a low-concentration detergent. The pre-treated residue is then fed into a screw press, where mechanical pressure is used to squeeze the material, causing the residual oil to seep out from the pores. The residue is then heated to a certain temperature and allowed to settle and separate into layers. The upper layer is liquid residual oil, and the lower layer is solid residue. The residue is then filtered through a filter cloth, filter element, or filter press to remove suspended solids. The purified residual oil is then used as the finished product.

[0004] The residue may clump together and have a dense fibrous structure, which can cause the residual oil inside to be trapped, resulting in resource waste. Therefore, a residue re-separation and residual oil extraction device is proposed to address the above problems. Utility Model Content

[0007] Preferably, the extraction tank has a cavity in the middle; a resistance wire is installed in the middle of the cavity; a heat insulation sleeve is fixed to the surface of the extraction tank; the inside of the extraction tank is heated by the resistance wire to evaporate and remove the small amount of water remaining after centrifugation, reducing the water content that causes the residual oil to deteriorate, extending its storage time or improving its applicability for subsequent processing.

[0010] Preferably, a material distribution plate is fixedly connected to the middle of the crushing chamber; the material distribution plate is triangular in shape; the inclined surface design of the triangular material distribution plate can guide the residue to slide down, so that the crushed material falls from the bottom of the crushing chamber into the separation cylinder, reducing residue accumulation and improving the overall residue utilization rate.

[0011] Preferably, a cover plate is hinged to one side of the guide cover; the cover plate is correspondingly arranged with the top of the guide cover; by reversing the cover plate during crushing to close the crushing chamber, the splashing of residue after crushing can be reduced, thus reducing material waste, while also reducing the pollution of the surrounding environment or equipment surface by the splashed residue, and increasing operational safety.

[0018] Specific implementation examples are given below.

[0019] like Figures 1 to 4As shown in the embodiment of this utility model, a residue re-separation and residual oil extraction device includes an extraction tank 1; a tank cover 11 is fixedly installed on the top of the extraction tank 1; a crushing chamber 12 is connected to the top of the tank cover 11; a set of first rotary motors 13 are installed on one side of the crushing chamber 12; multiple blades 14 are fixedly connected to the output end of the first rotary motors 13; a guide cover 15 is fixedly connected to the top of the crushing chamber 12; the guide cover 15 is funnel-shaped; a set of guide plates 16 are fixedly connected to the inner wall of the guide cover 15; the guide plates 16... 6 is inclined; a second rotary motor 17 is installed on the top of the tank cover 11; a separation cylinder 18 is fixedly connected to the output end of the second rotary motor 17; the separation cylinder 18 is set at the bottom of the tank cover 11; the separation cylinder 18 is rotatably connected to the inner wall of the extraction tank 1; a slag discharge pipe 19 is rotatably connected to the bottom of the separation cylinder 18; the slag discharge pipe 19 penetrates the bottom of the extraction tank 1; an oil discharge pipe 110 is fixedly connected to the bottom of the extraction tank 1; during operation, the first rotary motor 13 is turned on, causing its output end to drive the blade 14 to rotate, discharging the residue from the guide cover 1. 5. The residue is poured in from above, and enters between a set of blades 14 along the inclined surfaces of the guide cover 15 and the guide plate 16. The blades 14 work together to shear and crush the residue, which then falls from the bottom of the crushing chamber 12 into the separation cylinder 18. The second rotary motor 17 is turned on, driving the separation cylinder 18 to rotate. Centrifugal force is used to throw out the residual oil inside the residue. The residual oil passes through the gaps in the separation cylinder 18 and enters the bottom of the extraction tank 1. The oil outlet pipe 110 is connected to the oil pump. The oil pump is turned on to extract the residual oil for other processes. A valve is installed at the bottom of the slag outlet pipe 19. The valve discharges the residue inside the separator 18 along the slag outlet pipe 19. The first rotary motor 13 drives the blades 14 to shear and crush the residue, breaking down the agglomerate and exposing the residual oil inside. The second rotary motor 17 drives the separator 18 to rotate, using centrifugal force to throw the residual oil out of the crushed residue, which can increase the residual oil separation efficiency and recovery rate. The cooperation between the guide cover 15 and the guide plate 16 can guide the residue into the space between a set of blades 14, reducing the residue from sliding off the sides of the blades 14, thereby increasing the uniformity of crushing.

[0020] like Figure 4 As shown, the extraction tank 1 has a cavity 2 in the middle; a resistance wire 21 is installed in the middle of the cavity 2; a heat insulation sleeve 22 is fixed to the surface of the extraction tank 1; during operation, the resistance wire 21 is connected to an external power source, and turning on the power source causes the resistance wire 21 to generate heat, which is conducted to the inner wall of the extraction tank 1 to heat the residual oil and evaporate the water inside. The heat insulation sleeve 22 prevents the heat inside the extraction tank 1 from dissipating. By heating the inside of the extraction tank 1 through the resistance wire 21, the small amount of water remaining after centrifugation is evaporated and removed, reducing the water content that causes the residual oil to deteriorate, extending its storage time or improving its applicability for subsequent processing. At the same time, heating can increase the fluidity of the residual oil, reducing the residue of residual oil inside the extraction tank 1 and in the pipeline when it is pumped by the oil pump, further improving the recovery rate.

[0021] like Figure 5 As shown, a resonant ring 3 is fixedly connected to the bottom of the extraction tank 1; the resonant ring 3 is concentrically arranged with the bottom of the extraction tank 1; a sound wave head 31 is fixedly connected to the top of the resonant ring 3; a connecting line 32 is fixedly connected to the surface of the sound wave head 31; during operation, the connecting line 32 is connected to the sound wave generator, the switch is turned on, and the sound wave head 31 emits a sound wave, which is conducted to the surface of the resonant ring 3, and then the resonant ring 3 conducts the sound wave to the bottom of the extraction tank 1 to generate vibration. The sound wave generated by the sound wave head 31 is conducted to the bottom of the extraction tank 1 through the resonant ring 3, forming vibration, which causes the residual oil in the extraction tank 1 to form convection, increases the uniformity of heating of the residual oil, reduces local overheating that leads to oil deterioration, and at the same time accelerates the water evaporation efficiency, shortens the heating and dehydration time, and reduces energy consumption.

[0022] like Figures 1 to 4 As shown, a set of handles 4 are fixedly connected to the top of the extraction tank 1; a sleeve 41 is rotatably connected to the surface of the handle 4; during operation, the sleeve 41 is grasped to lift and move the extraction tank 1. The sleeve 41 rotates synchronously with the hand. By grasping the rotatable sleeve 41 when moving the extraction tank 1, it rotates synchronously with the hand movement, reducing friction between the hand and the handle 4, making the grip fit the direction of the hand's force, reducing hand pressure and discomfort during handling, and increasing the convenience of movement.

[0023] like Figure 2 As shown, a material distribution plate 5 is fixedly connected to the middle of the crushing chamber 12; the material distribution plate 5 is triangular in shape; during operation, the crushed residue falls from between a set of blades 14, contacts the top of the material distribution plate 5, and slides down the inclined surface, reducing the accumulation of residue in the middle of the crushing chamber 12. The inclined surface design of the triangular material distribution plate 5 can guide the residue to slide down, so that the crushed material falls from the bottom of the crushing chamber 12 into the separation cylinder 18, reducing the accumulation of residue and improving the overall residue utilization rate.

[0024] like Figure 1 As shown, a cover plate 6 is hinged to one side of the guide cover 15; the cover plate 6 is correspondingly arranged with the top of the guide cover 15; during operation, after the residue is put into the crushing chamber 12, the cover plate 6 is rotated so that it flips over and covers the top of the crushing chamber 12. By reversing the cover plate 6 during crushing to close the crushing chamber 12, the splashing of the crushed residue can be reduced, thus reducing material waste. At the same time, the splashed residue can be reduced to prevent pollution of the surrounding environment or equipment surface, thereby increasing operational safety.

[0025] Working principle: By turning on the first rotary motor 13, its output end drives the blades 14 to rotate, pouring the residue from above the guide cover 15. The residue enters between a set of blades 14 along the inclined surface of the guide cover 15 and the guide plate 16. The blades 14 work together to shear and crush the residue, which then falls from the bottom of the crushing chamber 12 into the separation cylinder 18. Turning on the second rotary motor 17 drives the separation cylinder 18 to rotate, using centrifugal force to throw out the residual oil inside the residue. The residual oil passes through the gaps in the separation cylinder 18 and enters the bottom of the extraction tank 1. The oil outlet pipe 110 is connected to the oil pump. Turning on the oil pump extracts the residual oil for other processes. A valve is installed at the bottom of the slag outlet pipe 19. Opening the valve discharges the residue inside the separation cylinder 18 along the slag outlet pipe 19. Resistance wire 21 An external power supply is connected, and the power is turned on to generate heat in the resistance wire 21, which is conducted to the inner wall of the extraction tank 1 to heat the residual oil and evaporate the water inside. The heat insulation sleeve 22 prevents the heat inside the extraction tank 1 from dissipating. The connecting wire 32 is connected to the sound wave generator, and the switch is turned on to make the sound wave head 31 emit sound waves, which are conducted to the surface of the resonant ring 3. The resonant ring 3 then conducts the sound waves to the bottom of the extraction tank 1 to generate vibration. The sleeve 41 is grasped, and the extraction tank 1 is lifted and moved. The sleeve 41 rotates synchronously with the hand, and the crushed residue falls from between a set of blades 14. After contacting the top of the distribution plate 5, it slides down the slope to reduce the accumulation of residue in the middle of the crushing chamber 12. After the residue is put into the crushing chamber 12, the cover plate 6 is rotated to flip it over and cover the top of the crushing chamber 12.
