[0033] With reference to Figures 1-4 The screen shaking part comprises four groups of piston sleeves 5, the four groups of piston sleeves 5 are symmetrically fixed on the outer wall of the primary filter hopper 2, the telescopic end of the piston sleeve 5 is sleeved with a screen shaking spring 51, the primary filter screen 3 is inserted and fixed on the telescopic end of the four groups of piston sleeves 5, a driving disc 52 is rotatably connected to the outer wall of the primary filter hopper 2, a lifting rocker 53 is rotatably connected to the driving disc 52, a lifting plate 532 is rotatably connected to the top of the lifting rocker 53 through a hinge seat 531, the top of the lifting plate 532 is fixedly connected to the side wall of the primary filter screen 3, a driving motor 54 is fixedly connected to the top of the processing box 1, and the rotating shaft of the driving motor 54 and the rotating shaft of the driving disc 52 are drivingly connected through a first belt pulley set 541.

[0034] Through the above structure, the driving motor 54 is started, the driving disc 52 is driven to rotate through the transmission of the first belt pulley set 541, the lifting rocker 53 with the lifting plate 532 reciprocatingly lifts and lowers, at this time, the primary filter screen 3 reciprocatingly lifts and lowers the telescopic end of the piston sleeve 5 in cooperation with the arrangement of the screen shaking spring 51, so as to produce reciprocating up and down shaking effect, so that the oil quickly passes through the primary filter screen 3, and the larger impurities in the oil are filtered out and retained in the primary filter screen 3, and the above shaking effect can effectively avoid the blockage of the primary filter screen 3 by the larger impurities in the oil, and effectively improve the filtering efficiency.

[0035] Referring to Figures 1-4 Wherein, the two groups of piston sleeve 5 cavity bottom of the same side are communicated by the exhaust pipe 6, the input end of the exhaust pipe 6 is communicated with the inner cavity of the processing box 1, and a one-way valve is arranged in the exhaust pipe 6; the two groups of piston sleeve 5 cavity side wall of the same side are communicated by the exhaust pipe 61, and a one-way valve is arranged in the exhaust pipe 61, the two sides of the exhaust pipe 61 are communicated by the gas guide pipe 62, the output end of the gas guide pipe 62 is rotatably connected with the blowing pipe 63, and the output end of the blowing pipe 63 faces the bottom of the primary filter screen 3.

[0037] Through the above structure, when the lifting rocker 53 pushes the primary filter screen 3 with the telescopic end of the piston sleeve 5 to move upwards, suction will be generated at the bottom of the piston sleeve 5 cavity, and the one-way valve in the exhaust pipe 6 will be opened at the same time, so that the gas in the processing box 1 is sucked into the piston sleeve 5 cavity, thereby reducing the air pressure in the processing box 1, making the gas bubble overflow from the inside of the oil, effectively improving the bubble removal effect and effectively improving the oil quality; when the lifting rocker 53 drives the primary filter screen 3 to move downwards, the gas in the piston sleeve 5 cavity will be compressed, thereby opening the one-way valve in the exhaust pipe 61, so that the above-mentioned sucked gas is blown to the bottom of the primary filter screen 3 along the exhaust pipe 61, the gas guide pipe 62 and the blowing pipe 63, so as to generate a downward air flow thrust at the top of the primary filter screen 3, so that the oil can pass through the primary filter screen 3 more quickly, and the oil filtering effect is improved.

[0038] Referring to Figure 6 , Figure 8 Wherein, the fine filter part includes an agitating shaft 7, the agitating shaft 7 penetrates the center of the fine filter disc 4 and is rotatably connected with the inner wall of the processing box 1 on both sides, a plurality of groups of filter blades 71 are fixedly arranged on the agitating shaft 7 in the fine filter disc 4 at equal intervals, the end of the filter blade 71 is fixedly connected with a blocking arc plate 711, the blocking arc plate 711 is rotatably attached to the inner wall of the fine filter disc 4, a blow-off pipe 72 is fixedly connected to the side wall of the fine filter disc 4, the input end of the blow-off pipe 72 is communicated with the bottom of the inner cavity of the fine filter disc 4, a fine filter screen 73 is fixedly connected to the bottom of the side of the fine filter disc 4 away from the blow-off pipe 72, and the end of the agitating shaft 7 is drivingly connected with the shaft of the driving motor 54 through a second belt pulley set 74.

[0039] It should be noted that the blocking arc plate 711 is arranged to first realize the intermittent communication between the liquid guide pipe 22 and the fine filter disc 4, effectively avoid too much gas entering the processing box 1 along the liquid guide pipe 22, and ensure the negative pressure exhaust effect; secondly, the blocking arc plate 711 can slide and clean the inner arc wall of the fine filter disc 4, and ensure the cleanliness of the inner arc wall of the fine filter disc 4,

[0040] Through the arrangement of the above structure, the preliminarily filtered oil will flow into the liquid guide hopper 21, and then enter the fine filter disc 4 through the liquid guide hopper 21 and the liquid guide pipe 22. At the same time, the driving motor 54 will also drive the stirring shaft 7 to rotate through the transmission of the second belt pulley set 74, so that the filter blades 71 rotate in the fine filter disc 4. When the blocking arc plate 711 separates from the output end of the liquid guide pipe 22, the preliminarily filtered oil will enter the fine filter disc 4 and pass through the multiple groups of rotating filter blades 71 to reach the bottom of the fine filter disc 4, thereby achieving secondary filtration of the oil.

[0041] Referring to Figures 5-7 Wherein, the outer wall of the stirring shaft 7 is fixed with multiple groups of stirring rods 8 at equal intervals, the inner wall of the stirring rod 8 is slidably connected with a knocking block 81, the stirring rod 8 is fixedly connected with a limiting ring 82 inside, the knocking block 81 and the limiting ring 82 are fixedly connected with a return spring 821, the stirring shaft 7 is provided with a pulling groove 83, the stirring rod 8 is connected with the inner cavity of the pulling groove 83, the pulling groove 83 is inserted with a pulling rod 84, the side of the knocking block 81 close to the pulling rod 84 is fixedly connected with a pulling rope 811, the other end of the pulling rope 811 is fixedly connected with the outer wall of the pulling rod 84, the outer wall of the treatment box 1 is fixedly connected with a positioning sleeve 85, and the positioning sleeve 85 is provided with a pulling part for driving the pulling rod 84 to move; the end of the stirring rod 8 extends into the positioning sleeve 85, the inner end of the pulling groove 83 close to the positioning sleeve 85 is provided with a cross-shaped insertion slot 831, the outer wall of the pulling rod 84 is fixedly connected with a cross-shaped insertion strip 841, the cross-shaped insertion strip 841 is inserted with the cross-shaped insertion slot 831, and the cross-shaped insertion strip 841 slides along the cross-shaped insertion slot 831; the pulling part includes two groups of dynamic magnetic plates 842, the pulling rod 84 extends into the positioning sleeve 85, the two groups of dynamic magnetic plates 842 are fixed on the two sides of the end of the pulling rod 84, the inner wall of the positioning sleeve 85 is fixedly connected with a static magnetic plate 851 on both sides, and the dynamic magnetic plate 842 and the static magnetic plate 851 repel each other.

[0042] It should be noted that the cooperation between the cross-shaped insertion strip 841 and the cross-shaped insertion slot 831 enables the pulling rod 84 and the stirring shaft 7 to rotate synchronously, and enables the pulling rod 84 to slide along the pulling groove 83.

[0043] Through the arrangement of the above structure, when the stirring shaft 7 rotates, the moving magnetic plate 842 in the positioning sleeve 85 will rotate together. At this time, the repulsion effect of the fixed magnetic plate 851 and the moving magnetic plate 842 will push the moving magnetic plate 842 to move away from the side of the fixed magnetic plate 851 together with the pull rod 84, so as to pull each group of knocking blocks 81 to move to the side of the compression reset spring 821 through the pull rope 811, so as to realize the force storage of the reset spring 821. When the fixed magnetic plate 851 and the moving magnetic plate 842 are out of the repulsion area, under the rebound effect of the reset spring 821, the knocking block 81 will be quickly reset, so as to impact the bottom of the inner wall of the stirring rod 8, thereby generating a vibration effect in the petroleum filtered in three steps, so that the gas contained in the petroleum quickly floats upward, thereby removing the gas impurities contained in the petroleum, and further improving the quality of the petroleum.

[0044] With reference to Figure 2 , Figure 4 and Figure 8 , wherein the side wall of the primary filter hopper 2 is fixedly connected with an oil inlet pipe 9, the oil inlet pipe 9 is fixedly connected with an oil pump 91, the side wall of the primary filter screen 3 is provided with a mounting groove 31, and the output end of the oil inlet pipe 9 is inserted into the mounting groove 31; the upper right is set, after the primary filter screen 3 is used, the fixed connection between the primary filter screen 3 and the telescopic end of the piston sleeve 5 is released, so that the primary filter screen 3 can be taken out of the primary filter hopper 2, so as to clean the impurities retained in the primary filter screen 3, thereby improving the convenience of use.

[0045] With reference to Figure 1 , Figure 2 and Figure 6 , wherein the bottom of the treatment box 1 is fixedly and communicatively connected with an oil discharge pipe 75, and the oil discharge pipe 75 and the drain pipe 72 are both provided with electromagnetic valves; by opening the corresponding electromagnetic valves in the oil discharge pipe 75 and the drain pipe 72, the filtered petroleum in the treatment box 1 and the residue retained in the fine filter disc 4 can be discharged respectively, thereby improving the convenience of use.

[0046] With reference to Figures 1-8In the application, when in use, the oil pump 91 is opened, and the just extracted oil is discharged into the primary filter screen 3 along the oil inlet pipe 9, and the driving motor 54 is opened, and through the transmission of the first belt pulley set 541, the driving disc 52 is driven to rotate, so that the lifting rocker 53 drives the lifting plate 532 to reciprocatingly lift, at this time, the setting of the shaking screen spring 51 is matched, so that the primary filter screen 3 reciprocatingly lifts the extension end of the piston sleeve 5, so as to generate reciprocating up-and-down shaking effect, so that the oil quickly passes through the primary filter screen 3, and the larger impurities in the oil are filtered out and retained in the primary filter screen 3, and the above shaking effect can effectively avoid the larger impurities in the oil from causing the primary filter screen 3 to be blocked, and effectively improve the filtering efficiency; then, the oil after the preliminary filtration will flow into the liquid guide hopper 21, and enter the precision filter disc 4 together with the liquid guide hopper 21 and the liquid guide pipe 22, and through the transmission of the second belt pulley set 74, the driving motor 54 will also drive the stirring shaft 7 to rotate, so that the filter blades 71 rotate in the precision filter disc 4, when the blocking arc plate 711 is separated from the output end of the liquid guide pipe 22, the oil after the preliminary filtration will enter the precision filter disc 4, and pass through a plurality of rotating filter blades 71 to reach the bottom of the precision filter disc 4, so as to realize secondary filtration of the oil, and finally the oil at the bottom of the precision filter disc 4 will continue to pass through the precision filter screen 73, and after the third filtration, it will enter the treatment box 1, so as to complete three-step filtration of the oil, effectively filter out the impurities contained in the oil, and improve the purity of the oil.

[0047] When the stirring shaft 7 rotates, the moving magnetic plate 842 in the positioning sleeve 85 will rotate together. At this time, the repulsion between the fixed magnetic plate 851 and the moving magnetic plate 842 will push the moving magnetic plate 842 to move away from the fixed magnetic plate 851 when they are in the repulsion area, so as to pull the pulling rod 84 together, and then pull the groups of knocking blocks 81 through the pulling rope 811 to move to one side of the compression return spring 821, so as to store the force of the return spring 821. When the fixed magnetic plate 851 and the moving magnetic plate 842 are out of the repulsion area, the knocking blocks 81 will be quickly reset under the rebounding action of the return spring 821, so as to impact the bottom of the inner wall of the stirring rod 8, thereby generating a vibration effect in the petroleum after three-step filtration, so that the gas contained in the petroleum quickly floats upward. At the same time, in the process of the lifting rocker 53 pushing the telescopic end of the piston sleeve 5 upward together with the initial filter screen 3, suction effect will be generated at the bottom of the cavity of the piston sleeve 5, and the one-way valve in the air suction pipe 6 will be opened at the same time, so that the gas in the treatment box 1 is sucked into the cavity of the piston sleeve 5, thereby reducing the air pressure in the treatment box 1, cooperating with the rotation and vibration of the stirring rod 8, so that the bubbles quickly overflow from the inside of the petroleum, effectively improving the bubble removal effect and the quality of the petroleum. When the lifting rocker 53 drives the initial filter screen 3 to move downward, the gas in the cavity of the piston sleeve 5 will be compressed, so as to open the one-way valve in the exhaust pipe 61, so that the above-mentioned sucked gas is blown to the bottom of the initial filter screen 3 along the exhaust pipe 61, the air guide pipe 62 and the air blowing pipe 63, so as to generate a downward air flow thrust at the top of the initial filter screen 3, so that the petroleum passes through the initial filter screen 3 more quickly, thereby improving the petroleum filtration effect.
