Description

Technical Field

[0001] The present invention relates to the technical field of oil purification treatment, and specifically to an oil purification treatment device. Background Art

[0002] Mineral oil is a widely used fossil energy source. During use, if affected by the following factors, mineral oil will become waste mineral oil: 1. Contaminated by foreign metal debris: During the use of mineral oil, due to the loose sealing of the system and machine housing, dust and gravel invade the oil; it is also easily contaminated by various mechanical metal debris (such as metal chips, dust, gravel, fiber materials, etc.). 2. Water absorption: If the lubrication system, hydraulic transmission system, or water cooling device of mechanical equipment is not tight enough, water will enter the oil; moisture in the air will also be absorbed by the oil, and its water absorption increases with the increase in oil temperature. 3. Thermal decomposition: When the oil comes into contact with mechanical equipment at high temperatures, the oil will undergo thermal decomposition, producing gums and coke, resulting in the loss of use value of the oil. 4. Oxidation: The main reason for the chemical change of oil during use is the oxidation effect of air. Oxidation will generate some harmful substances, such as acids, gums, asphalt, etc., making the oil darker in color, increasing in viscosity, increasing in acid value, and further resulting in precipitated sludge. 5. Dilution by fuel oil: This type of waste oil mainly refers to internal combustion engine lubricating oil. If part of the fuel oil does not burn completely and seeps into the lubricating oil, the lubricating oil will lose its original lubricating characteristics.

[0003] After retrieval, a Chinese patent with the publication number CN117482607A discloses a waste mineral oil recycling and treatment device, including a device body. The device body includes a processing device one, and an auxiliary processing device one and an auxiliary processing device two are provided on the top of the processing device one. An auxiliary processing device three is provided between the auxiliary processing device one and the auxiliary processing device two. Through the processing device one, and an auxiliary processing device one and an auxiliary processing device two are provided on the top of the processing device one, and an auxiliary processing device three is provided between the auxiliary processing device one and the auxiliary processing device two, so that the operator can directly feed the waste mineral oil into the interior of the processing device one through the auxiliary processing device three as needed, or enter the interior of the auxiliary processing device one or the auxiliary processing device two after passing through the auxiliary processing device three, thereby ensuring the diversity of waste mineral oil processing.

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation to the present invention.

[0020] The embodiments of the present invention will be described below according to its overall structure.

[0021] An oil purification treatment device, as Figures 1-11 shown, includes a filtering mechanism 1. The filtering mechanism 1 includes a filtering box 101. A plurality of fixed bars 102 are fixedly connected to the inner wall of the filtering box 101. A filter screen 103 is fixedly connected between two groups of fixed bars 102 at the same height. The mesh holes of the filter screen 103 located above are larger than those of the filter screen 103 below. A sealing strip 127 is fixedly connected to the edge of the filter screen 103, and the sealing strip 127 fits on the inner wall of the filtering box 101. Two groups of sliding bars 104 are respectively arranged below each group of filter screens 103. The sliding bars 104 are located at both ends of the filter screen 103. One group of guide frames 105 are respectively arranged at both ends of each group of sliding bars 104. Two groups of flap plates 111 are respectively rotatably connected to the inner walls of each group of guide frames 105. A torsion spring is arranged at the connection of the flap plate 111 and the guide frame 105. The guide frame 105 is fixedly connected to the inner wall of the filtering box 101. One group of sliding rods 106 are respectively fixedly connected to both ends of each group of sliding bars 104. Each group of sliding rods 106 are respectively slidably sleeved on the inner wall of one group of guide frames 105. A plurality of first synchronous belts 107 are installed on the inner wall of the filtering box 101. The connections of each group of first synchronous belts 107 with the filtering box 101 are respectively located below one group of guide frames 105. A pushing rod 108 is fixedly connected to the outer wall of each group of first synchronous belts 107. A plurality of motors 109 are fixedly connected to the outer wall of the filtering box 101. The output ends of each group of motors 109 are respectively fixedly connected to one group of first synchronous belts 107. One group of sliding frames 110 are respectively fixedly connected to both ends of each group of sliding bars 104. Each group of sliding frames 110 are respectively slidably sleeved on the outer wall of one group of pushing rods 108. The top end of the sliding bar 104 fits on the bottom end of the filter screen 103.

[0022] When the mineral oil passes through the upper filter screen 103, larger metal debris is filtered out. Then the mineral oil passes through the lower filter screen 103, and smaller metal debris is filtered out. During the above process, the motor 109 drives the first synchronous belt 107 to rotate, thereby driving the sliding frame 110 to rotate. During the rotation of the sliding frame 110, the pushing rod 108 is driven to move, thereby driving the sliding bar 104 to move, and further driving the sliding rod 106 to slide inside the guide frame 105, so that the sliding rods 106 below the same group of filter screens 103 approach each other, so that the sliding rods 106 move to Figure 9At the position shown in the figure, as the slider 104 driven by the synchronous belt moves, the sliding direction of the sliding rod 106 changes, causing the slider 104 to slide along the flap 111 to a position near the bottom inside the guide frame 105, so that the sliding rod 106 no longer pushes the filter screen 103 upward. As the sliding rod 106 continues to slide, the sliding rod 106 contacts another group of flaps 111, causing the other group of flaps 111 to be pushed by the sliding rod 106. When the sliding rod 106 slides to the end of the guide frame 105, the flap 111 separates from the sliding rod 106. At this time, the torsion spring rebounds and pushes the flap 111 to reset. As the first synchronous belt 107 continues to rotate, the push rod 108 pushes the sliding frame 110 to move in the reverse direction. At this time, the sliding rod 106 slides reversely inside the guide frame 105, causing the sliding rod 106 to slide along the flap 111 to a position near the top inside the guide frame 105, thereby raising the slider 104 and jacking up the filter screen 103, presenting the state as shown in Figure 7 In the figure. Repeating the above process makes the filter screen 103 wavy. Since there are two groups of sliders 104 at the bottom of each filter screen 103, the metal debris at the top of the filter screen 103 converges below the second synchronous belt 302. And the sealing strip 127 at the edge of the filter screen 103 closely adheres to the inner wall of the filter box 101, so that the mineral oil can only pass through the filter screen 103 and enter below the filter screen 103. During the filtering process, the fan 125 pushes the air to pass through the middle of the heating wire 126, and the hot air blows onto the mineral oil. The mineral oil is sprayed out from the nozzle 202 and contacts the hot air to be heated, so that the moisture inside the mineral oil is evaporated. And when the mineral oil drips from the upper filter screen 103 to the lower filter screen 103, the dripping makes the surface area of the oil liquid larger, so that the mineral oil is heated more fully.

[0023] Please refer specifically to Figures 2 to 6, a rear chamber 112 is provided at the bottom end of the filtration tank 101, a front chamber 113 is provided at one side of the bottom end of the filtration tank 101 away from the rear chamber 112, an oil outlet 114 communicating with the front chamber 113 is provided on the side wall of the filtration tank 101, a rear piston 115 is slidably connected to the inner wall of the rear chamber 112, a partition 116 is fixedly connected to the side wall of the rear piston 115, a front piston 117 is fixedly connected to the end of the partition 116, a connecting rod 118 is fixedly connected to the side of the front piston 117 away from the partition 116, the end of the connecting rod 118 extends to the outside of the filtration tank 101, a sliding plate 119 is slidably connected to the bottom end of the filtration tank 101, the side wall of the sliding plate 119 is fixedly connected to the end of the connecting rod 118, a hydraulic rod 120 is fixedly connected to the bottom end of the filtration tank 101, and the end of the hydraulic rod 120 is fixedly connected to the outer wall of the sliding plate 119. A first valve plate 121 is hinged to the inner wall of the rear chamber 112, an air inlet is provided on the side wall of the rear chamber 112 at a position corresponding to the first valve plate 121, a connecting pipe 122 is communicated with the top end of the rear chamber 112, a second valve plate 123 is hinged at the communicating position of the rear chamber 112 and the connecting pipe 122, a set of torsion springs are respectively arranged at the connection positions of the first valve plate 121 and the second valve plate 123 with the rear chamber 112. The feeding mechanism 2 includes an oil storage tank 201, the top end of the connecting pipe 122 is communicated with the side wall of the oil storage tank 201 near the top end, a plurality of spray heads 202 are communicated with the bottom end of the oil storage tank 201, the spray heads 202 extend into the filtration tank 101 and are located above the filter screen 103. A set of air inlets 124 are respectively provided on both sides of the filtration tank 101, a set of heating wires 126 are respectively fixedly connected at the communicating positions of each set of air inlets 124 with the filtration tank 101, a set of fans 125 are respectively fixedly connected to the inner walls of each set of air inlets 124, and each set of fans 125 are respectively located at the entrances of each set of air inlets 124.

[0024] The sliding plate 119 is pushed to reciprocate by the hydraulic rod 120, so that the sliding plate 119 continuously pushes and pulls the connecting rod 118, thereby driving the front piston 117 to reciprocate. During the reciprocating movement of the front piston 117, the rear piston 115 is driven to reciprocate by the partition plate 116. When the front piston 117 slides from the rear chamber 112 into the interior of the front chamber 113, the mineral oil flowing into the bottom end of the filter tank 101 is pushed out from the oil outlet 114. Due to the blocking of the partition plate 116, when the front piston 117 slides into the front chamber 113, the mineral oil cannot flow to the bottom end of the filter tank 101. At the same time, as the piston slides inside the rear chamber 112, a negative pressure is generated inside the rear chamber 112, thereby opening the first valve plate 121, and the outside air enters the rear chamber 112. When the front piston 117 and the rear piston 115 slide back in the reverse direction and reset, without the blocking of the partition plate 116, the mineral oil will flow into the bottom end of the filter tank 101, and the air inside the rear chamber 112 is squeezed, causing the first valve plate 121 to reset and the second valve plate 123 to open. Thus, the air inside the rear chamber 112 is pressurized into the interior of the storage tank 201, causing the mineral oil inside the storage tank 201 to be squeezed by the air and accelerate to spray out from the nozzle 202.

[0025] Please refer specifically to Figure 2 、 Figure 10 and Figure 11 The inner wall of the filter tank 101 is provided with a recovery mechanism 3 extending to the bottom end of the filter tank 101. The recovery mechanism 3 includes a diversion cover 301. The diversion cover 301 is communicated with the side wall of the filter tank 101. Two groups of second synchronous belts 302 are arranged at the communication part between the diversion cover 301 and the filter tank 101. Each group of second synchronous belts 302 is respectively located above a group of filter meshes 103. A group of flexible magnetic sheets 303 are respectively fixedly sleeved on the outer walls of each group of second synchronous belts 302. Two groups of scraping blades 307 are fixedly connected to the inner wall of the diversion cover 301. The ends of each group of scraping blades 307 are respectively attached to the outer walls of the flexible magnetic sheets 303. Two groups of collection grooves 304 are slidably sleeved at the bottom end of the diversion cover 301. A plurality of buckles 305 are respectively fixedly connected to the side walls of each group of collection grooves 304. A plurality of card slots 306 are formed on the outer wall of the diversion cover 301. The ends of each group of buckles 305 respectively extend into the inner walls of a group of card slots 306.

[0026] During the process of filtering the mineral oil, metal debris is continuously gathered in the middle of the filter mesh 103. While the second synchronous belt 302 rotates, it drives the flexible magnetic sheet 303 to rotate, so that the metal debris is adsorbed by the flexible magnetic sheet 303. Then, during the rotation of the flexible magnetic sheet 303, the metal debris is scraped off by the scraping blade 307 and enters the diversion groove, and finally converges into the collection groove 304 for collection. The collection groove 304 is fixed to the bottom end of the diversion cover 301 through the buckle 305 and the card slot 306, so that the collection groove 304 can be quickly disassembled and installed to facilitate the cleaning of the metal debris inside the collection groove 304.

[0027] During use, when the waste mineral oil passes through the surface of the filter screen 103, the metal debris in the waste mineral oil is filtered out. The sliding bar 104 reciprocates at the bottom of the filter screen 103, so that the filtered metal debris converges under the second synchronous belt 302, avoiding covering the entire upper surface of the filter screen 103, thereby preventing the mesh holes of the filter screen 103 from being blocked by metal debris, enabling the filter screen 103 to always maintain the filtering effect and extending the service life of the filter screen 103. Moreover, the electric heating wire 126 continuously heats the air, and the hot air is used to heat the mineral oil to accelerate the evaporation rate of the water contained in the mineral oil. The parts not involved in this device are the same as or can be implemented by the prior art.
