Description

Technical Field

[0001] The utility model relates to the technical field of vacuum pumps, in particular to a high-efficiency dust removal vacuum pump. Background Art

[0002] The sliding valve vacuum pump is the abbreviation of the sliding valve oil-sealed mechanical pump. It is a variable volume gas transmission pump with significant energy-saving effects, high vacuum degree, and large air extraction volume in the high vacuum range. When the sliding valve vacuum pump is working, it usually inhales a large amount of gas, which causes the dust particles in the gas to adhere to the pump. As the working time increases, the working effect of the sliding valve vacuum pump is poor, and it may even fail to work. Therefore, a dust removal vacuum pump is needed.

[0003] A Chinese patent discloses a high-efficiency dust removal vacuum pump with a publication number of CN219691753U, and the application date is 2023.03.13. The patented technology automatically removes dust in the airflow during the working process of the main body, thereby preventing the dust from being sucked into the vacuum pump body, thereby extending the service life; the dust removal device includes a first transmission shaft, a fan blade and a dust hood, and the driving mechanism is connected to the first transmission shaft, and drives it to drive the fan blade in the cavity to rotate circumferentially with the first transmission shaft as the center, and then the dust hood captures dust particles in the airflow during the rotation process. At the same time, the dust hood can be replaced regularly to ensure a good dust removal effect, and the dust hood can be reused, and only needs to be washed with water and dried, thereby saving the use cost. However, the above patent uses a dust hood to absorb dust entering the air, but the dust hood needs to be taken out and cleaned every once in a while. If it is not cleaned, it will affect the dust removal effect of the vacuum pump, and the dust hood is arranged inside the main body, which is inconvenient to judge whether the dust on the surface of the dust hood is spread, so it is possible that the dust removal effect is not ideal due to untimely cleaning of the dust hood. Therefore, the inventor provides a high-efficiency dust removal vacuum pump to solve the problems raised in the above background technology. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The high-efficiency dust removal vacuum pump starts the motor through an external power supply, and the output end of the motor drives the threaded rod to rotate, and the rotating threaded rod drives the cleaning block to move up and down, thereby cleaning the dust on the surface of the dust filter. When the cleaning block moves, it slides along the surface of the guide rod, thereby achieving the effect of guiding the cleaning block when it moves, and the dust enters the dust collection box through the dust discharge groove. In this way, the dust on the surface of the dust filter is cleaned, solving the problem of unsatisfactory filtering effect caused by untimely dust cleaning.

[0015] In addition, the high-efficiency dust removal vacuum pump inserts the dust box upward from the bottom of the connecting frame. The pressing force when the surface of the dust box contacts the plug block will cause the plug block to move inward and compress the support spring. When the dust box is fully inserted and the positioning groove corresponds to the position of the plug block, the support spring loses its compression force, so that the support spring drives the plug block to move outward and insert into the positioning groove, thereby fixing the dust box.

DETAILED DESCRIPTION

[0021] like Figure 1 , 2 As shown, a high-efficiency dust-removing vacuum pump comprises a vacuum pump body 10, a dust cover 20 is fixedly connected to the left side of the vacuum pump body 10, a connecting pipe 21 is fixedly connected to the left side of the dust cover 20; a dust filter 22 is fixedly connected inside the middle position of the dust cover 20; when in use, the connecting pipe 21 is connected to the output end of the object to be vacuumed, and then the vacuum pump body 10 is started, the vacuum pump body 10 inhales air through the connecting pipe 21, the air passes through the dust cover 20 and is filtered by the dust filter 22 before entering the inside of the vacuum pump body 10, and is finally discharged through the output end of the vacuum pump body 10.

[0022] refer to Figure 2 , 3 The upper and lower ends of the left side of the dust cover 20 are rotatably connected with a rotatable threaded rod 30, and a cleaning block 31 is threadedly connected to the threaded rod 30. The rear side of the cleaning block 31 is provided with a brush body (not shown in the figure) that fits the surface of the dust filter 22. The upper and lower ends of the right end of the dust cover 20 are fixedly connected with a guide rod 32, and the cleaning block 31 is slidably connected to the guide rod 32. When in use, the rotating threaded rod 30 drives the cleaning block 31 to move up and down, so as to clean the dust on the surface of the dust filter 22. When the cleaning block 31 moves, it slides along the surface of the guide rod 32, so as to guide the cleaning block 31 when it moves.

[0023] Specifically, a motor 35 is fixedly connected to the left side of the top of the dust cover 20, and the output end of the motor 35 is fixedly connected to the top of the threaded rod 30. When in use, the motor 35 is started by an external power supply, and the output end of the motor 35 drives the threaded rod 30 to rotate.

[0024] Preferably, a dust discharge groove 33 is provided at the bottom of the dust cover 20, and a fitting block 34 is fixedly connected to the bottom of the cleaning block 31. When the cleaning block 31 moves up and down, the dust on the surface of the dust filter 22 will be swept off, and the dust will fall into the dust discharge groove 33. In order to prevent the air entering from the connecting pipe 21 from being discharged from the dust discharge groove 33 in large quantities and affecting the normal operation of the vacuum pump body 10, the cleaning block 31 is moved to the bottom of the dust cover 20 in advance when the vacuum pump body 10 is used, so that the fitting block 34 covers the upper part of the dust discharge groove 33.

[0025] Since the amount of dust in the dust filter 22 is not large each time it is cleaned, it would be too troublesome to discharge it individually each time, so a collection mechanism is proposed.

[0027] Preferably, the outer surface of the plug 44 is an arc-shaped design that gradually becomes longer from bottom to top, and the side surface of the plug 44 is adapted to the cross-section of the fixing groove 42, thereby achieving a guiding effect on the movement of the plug 44; when in use, the dust box 50 is inserted upward from the bottom of the connecting frame 40, and the pressing force when the surface of the dust box 50 contacts the plug 44 will cause the plug 44 to move inward and compress the support spring 43 at the same time. When the dust box 50 is fully plugged in and the positioning groove 53 corresponds to the position of the plug 44, the support spring 43 loses its compression force, so that the support spring 43 drives the plug 44 to move outward and insert into the positioning groove 53, thereby fixing the dust box 50.

[0028] Preferably, the bottom of the connecting frame 40 is fixedly connected to a first sealing strip 41, the interior of the dust box 50 is fixedly connected to an abutment block 51, the top of the abutment block 51 is fixedly connected to a second sealing strip 52, the bottom of the first sealing strip 41 is arc-shaped, and the top of the second sealing strip 52 is a concave shape adapted to the bottom of the first sealing strip 41, so that after the dust box 50 is installed on the connecting frame 40, the first sealing strip 41 and the second sealing strip 52 fit together, thereby forming a sealed environment to prevent dust entering the interior of the dust box 50 from floating to the outside through the gap and causing environmental pollution.

[0029] Preferably, the left and right sides of the dust box 50 are fixedly connected with a connecting cover 54, the outer side of the connecting cover 54 is slidably connected with a movable rod 55, and the opposite sides of the two movable rods 55 are fixedly connected with pressing blocks 56; when the dust box 50 is to be taken out, the movable rods 55 on both sides are pressed inward, and the movable rods 55 drive the pressing blocks 56 to approach the corresponding side plug-in blocks 44 until the pressing blocks 56 push the plug-in blocks 44 out of the interior of the positioning groove 53, and then the dust box 50 can be taken out by sliding it downward.

[0030] The working principle of the utility model is: the motor 35 is started by an external power supply, the output end of the motor 35 drives the threaded rod 30 to rotate, and the rotating threaded rod 30 drives the cleaning block 31 to move up and down, so as to clean the dust on the surface of the dust filter 22, and the cleaning block 31 slides along the surface of the guide rod 32 when moving, so as to achieve the effect of guiding the cleaning block 31 when moving, and the dust enters the dust collecting box 50 through the dust exhaust groove 33.
