DETAILED DESCRIPTION
[0022] 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 technical personnel in this field without creative work are within the scope of protection of the utility model.
[0023] See also Figures 1 to 6 The utility model provides a technical solution: an automobile oil recovery and filtering device, comprising an oil return barrel 1, a filter chamber 2 is provided at the bottom of the oil return barrel 1, the oil return barrel 1 and the filter chamber 2 are welded as a whole through a frame, a water-oil separator 3 is connected to the bottom of the filter chamber 2 through a pipeline, the water-oil separator 3 is connected to an oil tank 4 and a water tank 5 through the oil outlet and water outlet pipelines provided therein, a processing chamber 6 is installed inside the oil return barrel 1, a first filter element 7 embedded in the bottom wall of the oil return barrel 1 is provided below the processing chamber 6, a bracket 8 is slidably connected to the inner wall of the filter chamber 2, and a second filter element 9 and a third filter element 10 are respectively installed inside the bracket 8.
[0024] A servo motor 601 is installed at the top axis of the processing chamber 6 through a shaft rod. The servo motor 601 is installed on the top cover of the oil return barrel 1 through bolts. A bearing 602 is installed on the inner wall of the top of the processing chamber 6.
[0025] In this embodiment, Figure 3 and Figure 4As shown, the processing chamber 6 is made of metal and has several through holes on its surface. The processing chamber 6 is connected to the inside of the oil return barrel 1 by the servo motor 601, and a threaded bottom cover is provided at the bottom of the processing chamber 6. At the same time, a gap is left between the processing chamber 6 and the first filter element 7. Waste oil contains metal particles generated by engine wear, and general filtering equipment usually uses static sedimentation to discharge such metal particles during filtering. Although it is effective, it increases the filtering time. Metal impurities are inherently large in granularity and have weight. Centrifugal separation is faster than sedimentation separation. During high-speed rotation, when the processing chamber 6 is driven by the servo motor 601 to rotate at high speed, solid particles or sediments suspended in the oil body can be more effectively separated. The substances are quickly separated by centrifugal force without waiting for a long sedimentation time. The separated granular solid waste will be trapped on the surface of the first filter element 7, and the spilled oil will be discharged into the interior of the filter chamber 2 through the first filter element 7.
[0026] In this embodiment, Figure 4 As shown, an external pipe opening 603 is installed inside the bearing 602, and one end of the external pipe opening 603 passes through the inside of the processing chamber 6 through the bearing 602, and the other end of the external pipe opening 603 passes through the top cover opened by the oil return barrel 1, and a threaded opening is opened on the surface of the external pipe opening 603; the waste oil needs to be processed inside the processing chamber 6. In order to achieve the dual nature of effective feeding and simultaneous filtration, one side of the external pipe opening 603 for oil inlet is installed inside the processing chamber 6 through the bearing 602. When the processing chamber 6 rotates, the external pipe opening 603 on the top for oil inlet is not disturbed.
[0027] In this embodiment, Figure 3 As shown, the first filter element 7 has a metal material in the middle and a grid-shaped surface, and the bottom of the oil return barrel 1 and the top of the filter chamber 2 are respectively provided with through holes for communication with each other, and the first filter element 7 is located between the through holes, and the diameter of the first filter element 7 is larger than the diameter of the through holes; many oil filtering devices have internal baffles for filtering that are inconvenient to disassemble, and the first filter element 7 for filtering large particles of solid waste is embedded in the bottom wall of the oil return barrel 1, and the processing chamber 6 is installed by a servo motor 601. When the barrel cover on the surface of the oil return barrel 1 is opened, a space for removing the first filter element 7 will be reserved, and a pull ring is welded on the surface of the first filter element 7, through which it can be removed from the inside of the oil return barrel 1 and the metal residue on the surface can be cleaned.
[0028] In this embodiment, Figure 5 and Figure 6As shown, a trapezoidal sealed chamber is provided inside the filter chamber 2, and the bracket 8 is slidably connected to the chamber through sliders at both ends of its outer wall, and a movable door corresponding to the position of the bracket 8 is provided on the outer side of the oil return barrel 1, and at the same time, the surface of the bracket 8 is formed by several hollow partitions to form a slot for plugging and connecting the second filter element 9 and the third filter element 10; although the first filter element 7 can filter metal impurities, there are still some solid particles due to dust, soil or combustion products in the waste oil, and these substances can only be adsorbed by the second filter element 9 and the third filter element 10 with a microporous structure inside. This type of filter material needs to be replaced regularly, and the second filter element 9 and the third filter element 10 are installed inside the equipment by using the bracket 8, and the bracket 8 adopts a semi-hollow partition structure, which is also convenient for the oil preliminarily filtered by the first filter element 7 to flow into the filter chamber 2 and then flow to the second filter element 9 and the third filter element 10 through the bracket 8 for further processing.
[0029] In this embodiment, Figure 5 and Figure 6 As shown, the second filter element 9 and the third filter element 10 form a trapezoidal distribution, and the second filter element 9 adopts a synthetic fiber paper filter element, and the filter element of the third filter element 10 is provided with activated carbon; the second filter element 9 and the third filter element 10 are arranged correspondingly according to the shape of the bracket 8. Compared with the traditional regular quadrilateral filter plate, the trapezoidal structural distribution can provide more filter media under the same size, thereby increasing the capture capacity of particles in the medium, thereby improving the filtering effect, and an activated carbon layer is provided inside the third filter element 10, which can absorb odor, pollutants and harmful chemicals in the engine oil, further improving the filtering effect.
[0030] The use method and advantages of the utility model: When the automobile oil recovery and filtering equipment is used, the working process is as follows:
[0031] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, firstly, the external pipe port 603 is connected to an external container for storing waste oil through a pipe and an oil pump, and a power source is driven. When the oil flows into the processing chamber 6 through the external pipe port 603, the processing chamber 6 rotates with the servo motor 601, and the oil rotates inside it at the same time. The metal particles in the oil will be thrown out through the through holes on the surface of the processing chamber 6 and trapped on the surface of the first filter element 7. When the oil is continuously processed, the liquid will also flow into the interior of the return oil barrel 1 and merge into the interior of the filter chamber 2 through the first filter element 7 and flow to the second filter element 9 and the third filter element 10. The second filter element 9 and the third filter element 10 can effectively absorb fine particles, dust and harmful chemicals that have not been filtered out from the upper part. Since the interior of the return oil barrel 1 adopts a centrifugal filtration method to remove large particles and metal impurities in the oil, and the interior of the filter chamber 2 adopts a sedimentation filtration method to remove small granular impurities remaining in the oil, the second filter element 9 and the third filter element 10 are used to remove the small particles. The oil after sedimentation filtration by the filter element 10 is transported to the inside of the water-oil separator 3 (model GF-2) through an oil pump and a pipeline. The main principle is to achieve separation based on the relative density difference between oil and water. Since the density of the injected oil is relatively light, it often floats on the surface of the water. Therefore, after the oil and water pass through the container for a period of time, the oil will naturally float to the upper part of the separator, and the water will settle to the lower part. The separator is provided with an outlet, so that the oil and water can be discharged separately. This is the prior art. The classified and discharged oil and water are discharged into the inside of the oil tank 4 and the water tank 5 respectively through the oil pump and the water pump. When the internal filter element needs to be replaced, the second filter element 9 and the third filter element 10 can be replaced by sliding the pull-out bracket 8 through the movable door outside the filter chamber 2. When removing the top cover on the surface of the oil return barrel 1, the first filter element 7 can be taken out and cleaned by pulling the pull ring on the surface through the tool hook, and the bottom cover at the bottom of the processing chamber 6 is threaded and can be disassembled to rinse or clean the inside.
[0032] The above shows and describes the basic principle, main features and advantages of the utility model. Technical staff in this industry should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model will have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
