Detailed Description

The present invention will be further described with reference to the accompanying drawings and embodiments.

In the specific implementation process, as shown in fig. 1 and 2, the lifting assembly 5 includes a support rod 51, a support plate 52, a screw rod 53 and a handle 54, two sets of symmetrically arranged support rods 51 are fixedly mounted on the side walls of the two ends of the air inlet channel 2, the support plate 52 is fixedly mounted between the tops of the two sets of support rods 51, the screw rod 53 is connected to the top of the support plate 52 through a thread, the handle 54 is fixedly sleeved on the top of the screw rod 53, and the bottom of the screw rod 53 is rotatably connected with the top of the filter plate 4.

Be equipped with spout 8 on the inside wall of inlet channel 2, the bottom fixed mounting of filter 4 has T type pole 7, and the horizontal end and the spout 8 sliding connection of T type pole 7.

It should be noted that: when the pump body 1 works, because the negative pressure suction force is overlarge, more dust and impurities in the air can be pumped into the air inlet channel 2, and wind is drawn into the pump body 1, but dust impurities in the wind are filtered and blocked by the filter plates 4 in the air inlet passage 2, and when the time elapses, the handle 54 can be grasped to rotate the lead screw 53, so that the lead screw 53 is screwed up on the support plate 52, because the filter plate 4 is rotationally connected with the screw rod 53 and the filter plate 4 is also connected with the sliding groove 8 on the inner wall of the air inlet channel 2 in a sliding way through the T-shaped rod 7, therefore, when the screw rod 53 is rotated upwards, the filter plate 4 is not driven to rotate, only the filter plate 4 is driven to move upwards, thereby can make filter 4 upwards slide and flush mutually with inlet channel 2's top, alright handle with the dust impurity that 4 tops of filter can filter and block off this moment, prevent that these dust impurities from falling into and causing the pump body 1 to block up the life who improves the pump body 1 in inlet channel 2.

Referring to fig. 2, the collecting assembly 6 includes a sliding sleeve 61, a connecting column 62, a collecting frame 63 and a first bolt 64, the sliding sleeve 61 is slidably connected to the wall of each of the two sets of support rods 51, the connecting column 62 is fixedly mounted on the sidewall of the sliding sleeve 61, the collecting frame 63 is mounted between the two sets of connecting columns 62, and the first bolt 64 is threadedly connected to the sidewall of the sliding sleeve 61.

The collecting assembly 6 further comprises a fixing sleeve 65 and a spring 66, the fixing sleeve 65 is fixedly installed on the rod wall of the supporting rod 51 close to the top, the spring 66 is connected in series on the rod wall of the supporting rod 51, one end of the spring 66 is fixedly connected with the bottom of the fixing sleeve 65, and the other end of the spring 66 is fixedly connected with the top of the sliding sleeve 61.

The surface of the filter plate 4 is of an inclined structure, and the top of the air inlet channel 2 and the top of one side of the collecting frame 63 are both of inclined structures.

It should be noted that: sliding sleeve 61 slides down, it flushes with inlet channel 2's top mutually to drive collection frame 63 downstream, and can make the spring 66 atress tensile, then it is fixed with sliding sleeve 61 to rotate first bolt 64 and support rod 51's lateral wall counterbalance, thereby can lock the position of collecting frame 63, when filter 4 is moved inlet channel 2's top, because the surface of filter 4 and inlet channel 2's top and the one side top of collecting frame 63 are the slope structure, so dust impurity that is filtered on the filter 4 and blocks down can automatic landing to collect frame 63, thereby can collect dust impurity, after handling the dust, it loosens sliding sleeve 61 to rotate first bolt 64 again, the top that can drive sliding sleeve 61 automatic upward movement reset to support rod 51 is relieved to spring 66 atress this moment.

Referring to fig. 2, the connection column 62 includes a sliding cylinder 621, a sliding rod 622 and a second bolt 623, the sliding cylinder 621 is fixedly mounted on the side wall of the sliding sleeve 61, the sliding rod 622 is slidably connected inside the sliding cylinder 621, the second bolt 623 is screwed on the side wall of the sliding cylinder 621, a thread groove is formed at one end of the sliding rod 622 located outside the sliding cylinder 621, a thread groove matched with the sliding rod 622 is formed in the side wall of the collection frame 63, and the sliding rod 622 is screwed with the collection frame 63 in a rotating manner.

It should be noted that: after all the dust and impurities fall into the collecting frame 63, the second bolt 623 can be loosened, and then the sliding rods 622 are rotated to unscrew the sliding cylinder 621, so that the collecting frame 63 can be detached from the two groups of sliding rods 622, and the collected dust and impurities can be conveniently treated.

The utility model provides a prevent oil-free vertical vacuum pump's theory of operation of passageway jam as follows: when the pump body 1 works, because the negative pressure suction force is too large, more dust and impurities in air can be pumped into the air inlet channel 2, and the air can be pumped into the pump body 1, but the dust and impurities in the air can be filtered and blocked by the filter plate 4 in the air inlet channel 2, when the time is long, the sliding sleeve 61 slides downwards to drive the collecting frame 63 to move downwards to be flush with the top end of the air inlet channel 2, the spring 66 can be stressed and stretched, then the first bolt 64 is rotated to abut against the side wall of the supporting rod 51 to fix the sliding sleeve 61, so that the position of the collecting frame 63 can be locked, then the handle 54 is grabbed to rotate the screw rod 53, the screw rod 53 is rotated upwards on the supporting plate 52, and because the filter plate 4 is rotatably connected with the screw rod 53, and the filter plate 4 is also slidably connected with the sliding groove 8 on the inner wall of the air inlet channel 2 through the T-shaped rod 7, the screw rod 53 cannot drive the filter plate 4 to rotate when the screw rod 53 rotates upwards, only the filter plate 4 is driven to move upwards, so that the filter plate 4 can slide upwards to be flush with the top end of the air inlet channel 2, at the moment, because the surface of the filter plate 4, the top of the air inlet channel 2 and the top of one side of the collecting frame 63 are both of an inclined structure, the dust and foreign substances blocked by the filtration on the filter plates 4 automatically slide down into the collection frame 63, the second bolt 623 may then be loosened, the slide bar 622 may then be rotated to unscrew the slide cylinder 621, so that the collecting frame 63 can be detached from the two sets of sliding bars 622, facilitating the disposal of the collected dust and impurities, when the dust is disposed, the first bolt 64 is rotated to loosen the sliding sleeve 61, and the spring 66 is relieved of force to drive the sliding sleeve 61 to automatically move upwards and return to the top of the supporting rod 51, thereby be convenient for clear up the inlet channel 2 of vacuum pump, prevent that dust rubbish from being inhaled in the inlet channel 2 and causing pump body 1 to block up.

The utility model discloses circuit and control that relate to are prior art, do not carry out too much repetition here.

The above only is the embodiment of the present invention, not limiting the scope of the present invention, all the equivalent structures or equivalent processes of the present invention are used in the specification and the attached drawings, or directly or indirectly applied to other related technical fields, and the same principle is included in the protection scope of the present invention.
