Description

Technical Field

[0001] The utility model relates to the technical field of new energy and energy-saving, in particular to a heating structure for improving the sedimentation speed of waste mineral oil. Background Art

[0002] Waste mineral oil is the oil that is replaced when it cannot be used anymore due to contamination by impurities, oxidation and heat, which changes its original physical and chemical properties. It mainly comes from the sludge and oil footings produced during oil extraction and refining; the sediment produced during the storage of mineral oils; the oil residue and filter media during the replacement and regeneration process of machinery, power, transportation and other equipment.

[0003] Sedimentation is generally carried out in a raw material tank. The working principle of the sedimentation tank is to use gravity to separate a mixture containing substances of different specific gravities. The feed enters the sedimentation tank through an inlet pipe. According to the density difference, the heavy substance sinks downward along the tank wall, and the light substance floats on top, forming two isolated layers. As the substances separate, the liquid at the lower end gradually becomes thicker and the liquid at the upper end becomes thinner. A pressure difference is generated at the interface between the two, which further promotes the sedimentation process. After the separation is completed, the upper liquid is discharged through the outlet pipe, and the lower liquid is discharged from the tank through the drain pipe. However, this method has a slow sedimentation speed, which makes the sedimentation efficiency of the sedimentation tank low. Therefore, a heating structure for increasing the sedimentation speed of waste mineral oil is proposed. Utility Model Content

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] See also Figure 1 In this embodiment, a heating structure for increasing the settling speed of waste mineral oil includes a settling tank 1, and support seats 2 are fixed at both left and right ends of the lower surface of the settling tank 1. A heating mechanism 3 for increasing the settling speed of the waste mineral oil is provided on the left side of the settling tank 1, and a stirring mechanism 4 for quickly mixing flocculant and waste mineral oil is provided on the right end of the upper surface of the settling tank 1.

[0032] In this embodiment, the left end of the upper surface of the sedimentation tank 1 is connected to an inlet pipe, and the lower surface of the sedimentation tank 1 is connected to an outlet pipe. Control valves are fixed on the outer surfaces of the inlet pipe and the outlet pipe. Waste mineral oil can be introduced into the inner cavity of the sedimentation tank 1 through the inlet pipe. The top of the left side wall of the inner cavity of the sedimentation tank 1 is connected to a flocculant inlet pipe, and the flocculant can be introduced into the inner cavity of the sedimentation tank 1 through the flocculant pipe. The right side of the sedimentation tank 1 is connected to a siphon.

[0033] It should be noted that the siphon tube can be connected to an external siphon device to extract the material at the upper end after stratification.

[0034] See also Figure 2-3 In order to increase the sedimentation speed of the waste mineral oil, the heating mechanism 3 in this embodiment includes a temperature sensor 31, a water tank 32, a water pump 33, a water pumping pipe 34, a coil 35 and a heating rod 36. The temperature sensor 31 is fixed to the left end of the top wall of the sedimentation tank 1 and is used to sense the temperature of the sedimentation tank 1 in real time. The water tank 32 is arranged on the left side of the sedimentation tank 1. The water pump 33 is fixed on the upper surface of the water tank 32. One end of the water pumping pipe 34 is connected to the water inlet end of the water pump 33. The coil 35 is connected to the water inlet end of the water pump 33. One end of 35 is connected to the water outlet end of the water pump 33. When the temperature of the inner cavity of the sedimentation tank 1 is lower than the set value, the water pump 33 can be started. The water inlet end of the water pump 33 draws the hot water in the inner cavity of the water tank 32 to the inner cavity of the coil 35 through the pumping pipe 34. The hot water can flow through the inner cavity of the coil 35 and can be guided by the coil 35. The heating rods 36 are evenly fixed on the inner top wall and the inner bottom wall of the water tank 32. The water in the inner cavity of the water tank 32 can be heated by the arranged heating rods 36.

[0035] In this embodiment, the other end of the water pumping pipe 34 passes through the inner top wall of the water tank 32 and extends to the inner cavity of the water tank 32. The other end of the coil 35 passes through the inner cavity of the settling tank 1 and extends to the bottom of the left side wall of the inner cavity of the settling tank 1 and is connected to a return pipe. The other end of the return pipe passes through the right side wall of the inner cavity of the water tank 32 and extends to the inner cavity of the water tank 32.

[0036] The number of the heating rods 36 is no less than four, and the no less than four heating rods 36 are evenly distributed on the inner top wall and the inner bottom wall of the water tank 32. The efficiency of heating the water temperature can be improved by setting up multiple heating rods 36.

[0037] It can be understood that the hot water can conduct heat to the waste mineral oil through the coil 35, so that the temperature of the surface of the waste mineral oil increases. At this time, the temperature of the hot water decreases, and the hot water with reduced temperature can enter the inner cavity of the return pipe through the coil 35, and finally flow back to the inner cavity of the water tank 32 for reheating. The circulation of hot water can increase the temperature of the surface of the waste mineral oil, allowing it to settle quickly.

[0038] See also Figure 4 In order to make the waste mineral oil and the flocculant mix quickly and evenly, the stirring mechanism 4 in this embodiment includes an electric push rod 41, a rack 42, a gear 43, a shaft 44 and a plurality of stirring blades 45. The electric push rod 41 is fixed to the right end of the upper surface of the sedimentation tank 1, and the rack 42 is fixed to the piston rod of the electric push rod 41. When the electric push rod 41 is started, the piston rod of the electric push rod 41 moves to the left, which can drive the rack 42 to move. The rack 42 and the gear 43 are meshed and connected. The shaft 44 is rotatably connected to the inner top wall of the sedimentation tank 1 through a bearing, and the upper surface of the shaft 44 passes through the inner top wall of the sedimentation tank 1. It extends to the upper side of the sedimentation tank 1 and the gear 43 is fixed on its upper end. The movement of the rack 42 drives the gear 43 to rotate, thereby rotating the shaft 44. The stirring blades 45 are fixed on the outer surface of the shaft 44. The rotation of the shaft 44 rotates the stirring blades 45 fixed at both ends of its outer surface, thereby stirring the waste mineral oil and flocculant. The extension and shortening of the piston rod of the electric push rod 41 can rotate the shaft 44 and the stirring blades 45 back and forth clockwise and counterclockwise through the rack 42 and the gear 43, and the mixing can be uniformly achieved by rotating the stirring blades 45 back and forth clockwise and counterclockwise.

[0039] In this embodiment, multiple stirring blades 45 are evenly distributed on the left and right ends of the outer surface of the shaft 44, the length between the stirring blades 45 on the left and right ends is smaller than the inner diameter of the coil 35, sliders are fixed on the left and right ends of the lower surface of the rack 42, and a slide groove is opened on the upper surface of the sedimentation tank 1, and the slider makes horizontal linear motion in the inner cavity of the slide groove.

[0040] The working principle of the above embodiment is:

[0041] (1) The waste mineral oil can be introduced into the inner cavity of the sedimentation tank 1 through the inlet pipe, and then the flocculant is introduced into the inner cavity of the sedimentation tank 1 through the flocculant tube. Then, the electric push rod 41 is started, and the piston rod of the electric push rod 41 moves to the left, which can drive the rack 42 to move. When the rack 42 moves, the slider fixed on its lower surface slides in the inner cavity of the slide groove, which can limit the movement of the rack 42. The movement of the rack 42 drives the gear 43 to rotate, and then the shaft 44 rotates. The rotation of the shaft 44 causes the stirring blades 45 fixed at both ends of its outer surface to rotate, so that the waste mineral oil and the flocculant can be stirred. The stirring blades 45 can be rotated back and forth clockwise and counterclockwise to make them evenly mixed.

[0042] (2) In order to increase the sedimentation rate of the waste mineral oil, the temperature of the inner cavity of the sedimentation tank 1 can be sensed in real time by the temperature sensor 31, and the water in the inner cavity of the water tank 32 can be heated by the heating rod 36. When the temperature of the inner cavity of the sedimentation tank 1 is lower than the set value, the water pump 33 can be started. The water inlet end of the water pump 33 pumps the hot water in the inner cavity of the water tank 32 into the inner cavity of the coil 35 through the pumping pipe 34. The hot water can flow through the inner cavity of the coil 35 and can be guided by the coil 35. At this time, the hot water can conduct heat to the waste mineral oil through the coil 35, so that the temperature of the surface of the waste mineral oil increases. At this time, the temperature of the hot water decreases, and the hot water with a reduced temperature can enter the inner cavity of the return pipe through the coil 35, and finally flow back to the inner cavity of the water tank 32 for reheating. The circulation of hot water can increase the temperature of the surface of the waste mineral oil, so that it can settle quickly.
