DETAILED DESCRIPTION

[0022] 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.

[0023] Reference Figures 1-4 A hydrochloric acid waste gas purification and treatment device includes a clean air chamber 1, the lower end of the clean air chamber 1 is fixedly connected to an outlet pipe 2, the end of the outlet pipe 2 away from the clean air chamber 1 is fixedly connected to an exhaust pump 3, the clean air chamber 1 is connected to a processing tank (the processing tank is disclosed in the Chinese patent with publication number CN213221619U and the subject name is a hydrochloric acid waste gas purification and treatment device). When the exhaust pump 3 is started, the neutralized gas will enter the clean air chamber 1, then enter the exhaust pump 3 through the outlet pipe 2, and be discharged through the exhaust pump 3.

[0024] A filter screen 4 is fixedly installed in the clean air chamber 1, and a mounting plate 5 is fixedly installed in the clean air chamber 1. The mounting plate 5 is located directly below the filter screen 4. A rectangular hole is provided on the mounting plate 5, and a movable plate 6 is horizontally slidably installed in the rectangular hole through a sliding assembly. Water-absorbing cotton 7 is fixedly installed on both sides of the movable plate 6, and two water-absorbing cottons 7 are both located in the rectangular hole. Drain holes 8 connected to the rectangular holes are symmetrically provided on the sides of the mounting plate 5. Drain pipes 9 connected to the interior are symmetrically fixedly connected to the surface of the clean air chamber 1. One end of the two drain pipes 9 is respectively connected to one end of the two drainage holes 8. Sealing plates 10 are fixedly installed on both sides of the movable plate 6. The upper surfaces of the two sealing plates 10 are in sealing contact with the lower surface of the mounting plate 5. A transmission assembly for driving the movable plate 6 to move back and forth in the rectangular hole is provided in the clean air chamber 1.

[0025] The sliding assembly includes two slide rails 11 fixedly mounted horizontally on the mounting plate 5 and two sliders 12 slidably sleeved on the slide rails 11. The two sliders 12 are fixedly mounted at both ends of the movable plate 6. The movable plate 6 is slidably mounted in the rectangular hole through the slide rails 11 and the sliders 12 to ensure that the movable plate 6 can move smoothly in the rectangular hole.

[0026] Two absorbent cottons 7 are installed in the rectangular hole, and the initial size of the two absorbent cottons 7 is the same as that of the rectangular hole. When the absorbent cottons 7 are installed in the rectangular hole, the two absorbent cottons 7 are fixedly connected to the two sides of the movable plate 6, and the two absorbent cottons 7 are in an extruded state. When the neutralized gas passes through the absorbent cotton 7, the moisture in the gas will be absorbed by the absorbent cotton 7, thereby preventing the moisture in the gas from entering the vacuum pump 3, effectively improving the service life of the vacuum pump 3.

[0027] The transmission assembly can drive the movable plate 6 to move back and forth in the rectangular hole. When the movable plate 6 moves to one side, it will squeeze the absorbent cotton 7 in the moving direction of the movable plate 6, and the absorbent cotton 7 on the other side will return to its original shape under its own elasticity. The absorbent cotton 7 will absorb the water when being squeezed, and then be discharged from the clean air chamber 1 through the drainage hole 8 and the drainage pipe 9. When the gas passes through the mounting plate 5, it will pass through the absorbent cotton 7 that is returning to its original shape. Therefore, when one absorbent cotton 7 squeezes and drains water, the other absorbent cotton 7 absorbs water. Through the reciprocating movement of the movable plate 6, the two absorbent cottons 7 are squeezed alternately, thereby ensuring the water absorbency of the absorbent cotton 7.

[0028] The two drainage holes 8 are respectively located on both sides of the movable plate 6. The total width of the two sealing plates 10 is the same as the width of the rectangular hole. When the movable plate 6 moves, it will drive the two sealing plates 10 to move. At this time, the bottom of the squeezed absorbent cotton 7 will be blocked by the sealing plate 10, which can prevent the water squeezed out of the absorbent cotton 7 from falling to the bottom of the mounting plate 5. The bottom of the absorbent cotton 7 that absorbs moisture is not blocked by the sealing plate 10, so that the gas can pass through the rectangular hole.

[0029] A rotating hole is provided at the upper end of the clean air chamber 1, and the transmission assembly includes a rotating disk 13 rotatably mounted above the mounting plate 5 by a driving component and a vertical rod 14 vertically fixedly mounted on the lower surface of the rotating disk 13. A strip groove 15 is provided at the upper end of the movable plate 6, and one end of the vertical rod 14 is inserted into the strip groove 15. A rotating hole is provided at the upper end of the clean air chamber 1, and the driving component includes a rotating shaft 16 vertically rotatably mounted in the rotating hole and a driving motor 17 fixedly mounted at the upper end of the clean air chamber 1, the upper end of the rotating shaft 16 is fixedly connected to the output shaft of the driving motor 17, and the lower end is fixedly connected to the rotating disk 13, a through hole is provided on the filter screen 4, and one end of the rotating shaft 16 passes through the through hole.

[0030] When the driving motor 17 drives the rotating shaft 16 to rotate, it will drive the rotating disk 13 to rotate directly above the mounting plate 5. When the rotating disk 13 rotates, it will drive the vertical rod 14 to rotate around the rotating shaft 16. At this time, the vertical rod 14 will drive the movable plate 6 to move horizontally in the rectangular hole, and at the same time, one end of the vertical rod 14 slides in the strip groove 15.

[0031] A plurality of arc-shaped scraping strips 18 are fixedly mounted on the rotating shaft 16, and the plurality of arc-shaped scraping strips 18 are in sliding contact with the upper surface of the filter screen 4. During the rotation of the rotating shaft 16, the plurality of arc-shaped scraping strips 18 are driven to rotate on the filter screen 4. The arc-shaped scraping strips 18 can push the impurities accumulated on the filter screen 4 to the side wall of the clean air chamber 1, thereby preventing the impurities from accumulating on the filter screen 4 and affecting the filtering effect of the filter screen 4.

[0032] In the utility model, when the neutralized gas passes through the absorbent cotton 7, the moisture in the gas will be absorbed by the absorbent cotton 7. At the same time, the transmission component can drive the movable plate 6 to move back and forth in the rectangular hole. When the movable plate 6 moves to one side, the absorbent cotton 7 in the moving direction of the movable plate 6 will be squeezed, and the absorbent cotton 7 on the other side will return to its original shape under its own elasticity. The absorbent cotton 7 will be squeezed out and then discharged from the clean air chamber 1 through the drainage hole 8 and the drainage pipe 9. Therefore, when one absorbent cotton 7 squeezes out water, the other absorbent cotton 7 absorbs moisture. Through the reciprocating movement of the movable plate 6, the two absorbent cottons 7 are squeezed alternately, thereby ensuring the water absorbency of the absorbent cotton 7, preventing moisture in the gas from entering the air pump 3, and effectively improving the service life of the air pump 3.

[0033] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
