DETAILED DESCRIPTION

In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with an embodiment. The embodiment is only used to explain the present invention and does not constitute a limitation on the protection scope of the present invention.

As shown in Figures 1, 2, 3, and 4, an intermediate pump for an air source unit is proposed in this embodiment, including a pump chassis 1, an exhaust window 2 is provided at the upper end of the pump chassis 1, a fan 3 is fixedly connected to the exhaust window 2, an air inlet window 4 is provided on one side of the pump chassis 1, a filter plate 5 is fixedly connected to the air inlet window 4, and the exhaust window 2 and the air inlet window 4 are both fixedly connected to the pump chassis 1; the external air flow enters the pump chassis 1 through the air inlet window 4, and then is discharged through the exhaust window 2, and the filter plate 5 is used to filter dust in the air flow.

The filter plate 5 may have the problem of dust accumulation during long-term use. An adjustment plate 6 is provided on the front of the air inlet window 4. A brush plate 7 is provided on the side of the adjustment plate 6 facing the filter plate 5. The brush plate 7 is slidably connected to the adjustment plate 6. The side of the brush plate 7 away from the adjustment plate 6 contacts the filter plate 5.

A reciprocating lifting assembly for controlling the rise and fall of the adjustment plate 6 is provided on the outside of the air inlet window 4, and a reciprocating driving device for pushing the brush plate 7 to swing left and right is provided at the connection between the adjustment plate 6 and the brush plate 7. The reciprocating lifting assembly controls the rise and fall of the adjustment plate 6, and the adjustment plate 6 drives the brush plate 7 to move together during the rise and fall, so as to brush the surface of the filter plate 5 up and down. During the process of brushing up and down, the reciprocating driving device will push the brush plate 7 to swing left and right. The two different brushing actions can further clean the stubborn stains on the surface of the filter plate 5, ensure the smooth flow of gas, and make cleaning quick and convenient.

About the reciprocating lifting assembly: The reciprocating lifting assembly includes an adjustment box 8 arranged on one side of the air inlet window 4, the adjustment box 8 is fixedly connected to the air inlet window 4, a movable groove 10 is opened on the front of the adjustment box 8, a nut seat 12 and a reciprocating screw 11 are arranged in the movable groove 10, the nut seat 12 is sleeved on the outside of the reciprocating screw 11 and is threadedly connected to the reciprocating screw 11, a first motor 9 is arranged on the upper end of the adjustment box 8, the output end of the first motor 9 is fixedly connected to the upper end of the reciprocating screw 11, the nut seat 12 is fixedly connected to one end of the adjustment plate 6, and the nut seat 12 is slidably connected to the movable groove 10. When cleaning the surface of the filter plate 5, the first motor 9 will drive the reciprocating screw 11 to rotate, and the reciprocating screw 11 cooperates with the nut seat 12 during the rotation, driving the nut seat 12 to move along the rod of the reciprocating screw 11, and the movable groove 10 guides the nut seat 12 by cooperating with the nut seat 12. When the nut seat 12 moves, the adjustment plate 6 will also move, and the reciprocating screw 11 can make the nut seat 12 realize reciprocating motion without changing the rotation direction of the main shaft.

The brush plate 7 is arranged on the back of the adjustment plate 6 and can slide horizontally left and right on the back of the adjustment plate 6. Specifically, at least two sliders 16 are arranged on the front of the brush plate 7. The sliders 16 are fixedly connected to the brush plate 7. The end of the slider 16 away from the brush plate 7 is slidably connected to the limiting groove 15 provided on the front of the adjustment plate 6. The limiting groove 15 is provided with a limiting rod 19 and a spring 20. The two ends of the spring 20 are fixed to the groove wall of the limiting groove 15. The spring 20 penetrates the slider 16 and is slidably connected to the slider 16. The limiting rod 19 is fixedly connected to both sides of the slider 16. The end of the limiting rod 19 away from the slider 16 is fixedly connected to the groove wall of the limiting groove 15. The slider 16 can slide along the limiting groove 15. When the slider 16 moves, the brush plate 7 will also move. The limiting rod 19 in the limiting groove 15 is used to limit the slider 16 so that the slider 16 will not be separated from the limiting groove 15.

About the reciprocating drive device: The reciprocating drive device includes a second motor 17 and a deflection wheel 18. The mounting end of the second motor 17 is fixedly connected to the upper end of the adjustment plate 6. The output end of the second motor 17 is fixedly connected to the deflection wheel 18. The deflection wheel 18 is placed on one side of one of the sliders 16 and contacts the slider 16. The second motor 17 drives the deflection wheel 18 to rotate. During the rotation, the deflection wheel 18 pushes the slider 16 through the protrusion on its outer side. After being pushed, the slider 16 slides along the limit groove 15. When the protrusion on the deflection wheel 18 stops pushing the slider 16, the slider 16 will reset in the rebound of the limit rod 19, thereby realizing the horizontal reciprocating motion of the adjustment plate 6.

In order to facilitate the staff to collect the cleaned dust, a dust collecting box 13 is provided at the lower end of the air inlet window 4, and the dust collecting box 13 is detachably connected to the air inlet window 4.

The brush plate 7 slides along the surface of the filter plate 5 to scrape off the dust and dirt attached to the surface of the filter plate 5, and the fallen dust and dirt enter the dust collecting box 13 through the slag discharge port 14.

More specifically, first bolt fixing plates are provided at both ends of the ash box 13, second bolt fixing plates are provided at both sides of the air inlet window 4, fixing bolts are mounted on the second bolt fixing plates, the fixing bolts penetrate the first bolt fixing plates and the second bolt fixing plates, and the fixing bolts are threadedly connected with the first bolt fixing plates and the second bolt fixing plates. The ash box 13 is fixed to the lower end of the air inlet window 4 by bolt connection. When the ash box 13 is full of dust, the fixing bolts on both sides of the ash box 13 are unscrewed from the second bolt fixing plates, and the ash box 13 can be directly removed from the lower end of the air inlet window 4.

Working principle: External airflow enters the pump case 1 through the air inlet window 4, and then is discharged through the exhaust window 2. The filter plate 5 is used to filter the dust in the airflow. The reciprocating lifting assembly controls the adjustment plate 6 to rise and fall. The adjustment plate 6 drives the brush plate 7 to move together during the rise and fall, and brushes the surface of the filter plate 5 up and down. During the up and down brushing process, the reciprocating drive device will push the brush plate 7 to shake left and right. The two different brushing actions can further clean the stubborn stains on the surface of the filter plate 5, ensure the smooth flow of gas, and make cleaning quick and convenient.
