[0019] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.
[0020] Please see Figure 1-3 This utility model provides a technical solution: an oil filtration device, including a housing 1, a box 2 fixedly installed on one outer wall of the housing 1, a connecting port on one side of the housing 1, the housing 1 communicating with the box 2 through the connecting port, a fixing plate 3 and a hollow plate 5 fixedly installed on the inner wall of the housing 1, the hollow plate 5 being located above the fixing plate 3, the fixing plate 3 and the hollow plate 5 dividing the interior of the housing 1 from bottom to top into a feeding chamber, a pressure differential chamber and a discharging chamber, a filter screen 4 embedded in the fixing plate 3, and also including an acceleration structure installed between the fixing plate 3 and the hollow plate 5, the acceleration structure being used to accelerate the filtration speed of the filter screen 4 on the oil, and a cleaning structure installed on the box 2, the cleaning structure being used to clean the impurities filtered out by the filter screen 4.
[0021] Furthermore, the acceleration structure includes a motor A7, a reciprocating screw 8, a piston 9, and a U-shaped connecting frame 10. The motor A7 is fixedly installed on the outer wall of the other side of the housing 1. The reciprocating screw 8 is rotatably installed on the inner wall of the other side of the housing 1. The piston 9 is slidably installed in the differential pressure chamber. The U-shaped connecting frame 10 is fixedly installed on one side of the piston 9 and threaded onto the reciprocating screw 8. The output shaft of the motor A7 passes through the other side of the housing 1 and is fixedly installed at one end of the reciprocating screw 8. When the motor A7 is started, the output shaft of the motor A7 drives the reciprocating screw 8 to rotate. The rotation of the reciprocating screw 8 causes the U-shaped connecting frame 10 and the piston 9 to move back and forth. When the piston 9 moves to the left, it can reduce the pressure inside the differential pressure chamber, allowing the oil inside the feed chamber to enter the differential pressure chamber. When the piston 9 moves to the right, it can increase the pressure inside the differential pressure chamber, allowing the oil inside the differential pressure chamber to be discharged through the filter screen 4 and the discharge pipe 14, accelerating the speed at which the oil passes through the filter screen 4 and improving the oil filtration efficiency.
[0022] Furthermore, the cleaning structure includes a motor B11, a rotating drum 12, and a scraper 13. The motor B11 is fixedly installed on the top outer wall of the housing 2. The rotating drum 12 is rotatably installed on the top and bottom of the inner side of the housing 2. The scraper 13 is fixedly installed on the outer wall of the rotating drum 12. The output shaft of the motor B11 passes through the top of the housing 2 and is fixedly installed on the top of the rotating drum 12. There are eight discharge pipes 15 arranged in a circular array. The scraper 13 extends into the interior of the housing 1. When the motor B11 is started, the output shaft of the motor B11 drives the rotating drum 12 and the scraper 13 to rotate. The rotation of the scraper 13 can push the impurities filtered out by the filter screen 4, which can clean the impurities filtered out by the filter screen 4, prevent impurities from accumulating on the top of the filter screen 4, and ensure the filtration effect of the filter screen 4.
[0023] Furthermore, a feed pipe 6 is fixedly installed on the hollow plate 5, and a discharge pipe 14 is fixedly installed on the bottom of the box body 1. Both the feed pipe 6 and the discharge pipe 14 are equipped with one-way valves.
[0024] Furthermore, a waste discharge pipe 15 is fixedly installed at the bottom of the housing 2, and the waste discharge pipe 15 is equipped with a valve.
[0025] Furthermore, a rinsing port is provided on the top of the housing 2 to facilitate rinsing of the scraper 13.
[0026] Furthermore, a support leg 16 is fixedly installed on the bottom outer wall of the housing 1, and a caster 17 is movably installed at the bottom end of the support leg 16.
[0027] Working principle: When oil is poured into the feed chamber, the output shaft of motor A7 drives the reciprocating screw 8 to rotate. The rotation of the reciprocating screw 8 causes the U-shaped connecting frame 10 and piston 9 to move back and forth. When piston 9 moves to the left, it can reduce the pressure inside the differential pressure chamber, allowing the oil inside the feed chamber to enter the differential pressure chamber. When piston 9 moves to the right, it can increase the pressure inside the differential pressure chamber, allowing the oil inside the differential pressure chamber to be discharged through the filter screen 4 and the discharge pipe 14, thus accelerating the oil filtration efficiency. When the oil passes through the filter screen 4, impurities in the oil can be filtered out. When motor B11 is started, the output shaft of motor B11 drives the rotating drum 12 and scraper 13 to rotate. The rotation of scraper 13 can push the impurities filtered out by the filter screen 4 to the top of the discharge pipe 15. Due to gravity, the impurities will fall into the discharge pipe 15. By opening the valve, the impurities can be discharged.
[0028] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
