The primary function of a vacuum pump is to reduce the internal pressure by extracting gas from a closed container or system to the desired low pressure.

[0003] The automatic oiling device of the oil-type rotary vane vacuum pump disclosed in publication number CN204984904U includes an oil inlet, a metal tube, a flow control valve, and an oil suction pipe, one end of the metal tube is connected to the oil inlet, and the other end is connected to the flow control valve. One end of the oil suction pipe is connected to the flow control valve, and the other end is a free end extending into the empty oil barrel of the vacuum pump. The above application document sucks in the vacuum pump oil through the negative pressure generated by the vacuum pump suction port during operation, and adjusts the flow rate through the flow control valve. The operation is convenient, simple and fast. However, in actual use, some impurities may enter the vacuum pump oil during storage, resulting in impurities in the inhaled oil body, thereby affecting the service life of the vacuum pump. Utility Model Content

[0004] In view of the shortcomings of the prior art, the present invention provides a feeding device with a filtering structure, which solves the problems raised in the above background technology. To achieve the above purpose, the present invention is implemented through the following technical solutions: a feeding device with a filtering structure, comprising a filter tube body, the filter tube body is connected to an oil suction pipe through a flange, a filtering mechanism is provided inside the filter tube body, an angle adjustment component is provided on the side of the filter tube body away from the oil suction pipe, the filtering mechanism comprises a filter plate, the filter plate is rotatably connected to a rotating rod, the rotating rod is fixedly connected to a scraper, a fixed block 1 is fixedly connected to the inner wall of the filter tube body, the fixed block 1 is arranged on the side of the filter plate away from the oil suction pipe, a fixed block 2 is fixedly connected to the inner wall of the filter tube body, the fixed block 1 is elastically connected to the filter plate through a spring, a slide is provided on the rotating rod, a control bar is fixedly connected to the fixed block 1, and the control bar is slidably connected to the rotating rod through the slide.

[0005] Preferably, the length of the scraper is slightly smaller than the difference between the radius of the filter plate and the length of the second fixed block. By setting the length of the scraper, it is ensured that the scraper will not be affected by colliding with the first fixed block or the second fixed block during rotation, thereby ensuring the cleaning effect.

[0006] Preferably, the shape of the slide is a threaded type, and the width of the slide matches the end of the control strip. Through the setting of the threaded slide, the control strip can drive the rotating rod to rotate through the slide, thereby achieving the expected effect.

[0007] Preferably, the angle adjustment assembly includes a fixed tube, which is fixedly connected to the filter tube body.

[0009] Preferably, the outer wall shape of the rotating tube in contact with the fixed tube and the fixed ring is spherical, and the friction between the rotating tube and the fixed tube is relatively large. The spherical shape allows the spherical part of the rotating tube to rotate inside the fixed tube and the fixed ring.

[0010] The utility model provides a feeding device with a filtering structure, which has the following beneficial effects:

[0011] (1) The utility model sets a filtering mechanism. When the filter plate is clogged with impurities, the filter plate is moved by suction, thereby causing the rotating rod to move relative to the control bar.

The filter plate is reset under the action of the spring to ensure the filtering effect.

[0012] (2) The present invention sets an angle adjustment component, and through the connection between the fixed tube and the filter tube body, the oil inside the filter tube body can flow into the fixed tube, and through the shape setting of the fixed tube and the fixed ring, it is ensured that the rotating tube can rotate inside the fixed tube and the fixed ring, so as to adjust the angle of the rotating tube, so that the refueling holes with different inclination angles have better refueling effects.

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Example

[0019] See also Figure 1-3 , a feeding device with a filtering structure, including a filter tube body 1, the filter tube body 1 is connected to the oil suction pipe 3 through a flange 2, a filter mechanism 4 is arranged inside the filter tube body 1, and an angle adjustment component 5 is arranged on the side of the filter tube body 1 away from the oil suction pipe 3, the filter mechanism 4 includes a filter plate 41, the filter plate 41 is rotatably connected to a rotating rod 42, and the rotating rod 42 is fixedly connected to a scraper 43, and a fixed block 1 44 is fixedly connected to the inner wall of the filter tube body 1, and the fixed block 1 44 is arranged on the side of the filter plate 41 away from the oil suction pipe 3, and a fixed block 2 45 is fixedly connected to the inner wall of the filter tube body 1, and the length of the scraper 43 is slightly smaller than the difference between the radius of the filter plate 41 and the length of the fixed block 2 45. By setting the length of the scraper 43, it is ensured that the scraper 43 will not be affected by colliding with the fixed block 1 44 or the fixed block 2 45 during the rotation process, thereby ensuring the cleaning effect, and the fixed block 1 44 and the fixed block 2 The filter plate 41 is elastically connected by a spring 46, and a slide 47 is provided on the rotating rod 42. A control bar 48 is fixedly connected to the fixed block 44, and the control bar 48 is slidably connected to the rotating rod 42 through the slide 47. The slide 47 is in the shape of a threaded type, and the width of the slide 47 fits with the end of the control bar 48. Through the setting of the threaded slide 47, the control bar 48 can drive the rotating rod 42 to rotate through the slide 47, thereby achieving the expected effect. By setting the filtering mechanism 4, when the filter plate 41 is blocked by impurities, the filter plate 41 is moved by suction, thereby causing the rotating rod 42 to move relative to the control bar 48, and the rotating rod 42 is driven to rotate by the joint action of the control bar 48 and the slide 47, thereby causing the scraper 43 to rotate, thereby scraping off the impurities on the filter plate 41, and under the action of the spring 46, the filter plate 41 is reset to ensure the filtering effect.

[0020] When in use, the staff first puts the oil suction pipe 3 into the oil barrel, and then connects the filter tube body 1 to the oil inlet of the vacuum pump through the angle adjustment component 5. At this time, the oil enters the oil inlet under the suction of the vacuum pump and is filtered by the filter plate 41. When the filter plate 41 is blocked, since the suction of the oil inlet still exists, the filter plate 41 moves toward the side of the oil inlet of the vacuum pump under the combined action of the extrusion of the oil and the suction of the vacuum pump. At this time, the rotating rod 42 is driven by the filter plate 41. The rotating rod 42 moves. Since the rotating rod 42 is slidably connected to the control bar 48 through the slide 47, the slide 47 rotates the rotating rod 42 under the control of the control bar 48, and drives the scraper 43 to rotate through the rotating rod 42, so that the scraper 43 scrapes off the impurities attached to the filter plate 41, allowing the oil to pass through the filter plate 41 into the vacuum pump. When the impurities attached to the filter plate 41 are cleared, the filter plate 41 is reset under the drive of the spring 46, thereby ensuring that the filter plate 41 can still be cleaned if it is blocked next time. Example

[0021] See also Figure 1-4 On the basis of embodiment 1, the angle adjustment component 5 includes a fixed tube 51, which is fixedly connected to the filter tube body 1. The interior of the fixed tube 51 is communicated with the interior of the filter tube body 1. The fixed tube 51 is connected to a fixing ring 52 by a bolt. The inner wall shapes of the fixed tube 51 and the fixing ring 52 are both hemispherical, and a sealing ring is provided at the connection between the fixed tube 51 and the fixing ring 52. The hemispherical setting makes it convenient for the rotating tube 53 to rotate inside the fixed tube 51 and the fixing ring 52. The setting of the sealing ring ensures that the oil will not flow out through the gap between the fixed tube 51 and the fixing ring 52. A rotating tube 53 is provided inside the fixing ring 52. The outer wall shape of the rotating tube 53 in contact with the fixed tube 51 and the fixing ring 52 is The shape is spherical, and the friction between the rotating tube 53 and the fixed tube 51 is relatively large. The spherical shape allows the spherical part of the rotating tube 53 to rotate inside the fixed tube 51 and the fixed ring 52. The large friction ensures that after the rotating tube 53 is rotated to a suitable position, the position will not change without external force, thereby ensuring the use effect. Through the connection between the fixed tube 51 and the filter tube body 1, the oil inside the filter tube body 1 can flow into the fixed tube 51, and through the shape setting of the fixed tube 51 and the fixed ring 52, it is ensured that the rotating tube 53 can rotate inside the fixed tube 51 and the fixed ring 52, so as to adjust the angle of the rotating tube 53, so that the refueling holes with different inclination angles have a better refueling effect.

[0022] During use, based on Example 1, the staff first rotates the rotating tube 53 so that the rotating tube 53 moves to an angle that is exactly consistent with the inclination angle of the oil inlet of the vacuum pump, and then puts the end of the rotating tube 53 into the oil inlet, so that the oil inside the rotating tube 53 can enter the vacuum pump, thereby allowing the oil to enter the filter tube body 1 through the oil suction pipe 3 and then enter the fixed tube 51, and then enter the rotating tube 53 through the fixed tube 51, and finally enter the vacuum pump.
