Therefore, a device is urgently needed to filter the acid mist generated during the chrome plating process. Summary of the invention

[0011] By adopting the above technical solution, when acid mist enters the interior of the treatment box, the acid mist drives the driving plate located inside the gas blocking hood to rotate. The driving plate drives the rotating shaft to rotate during the rotation process.

The air guide component cooperates with a fan to drive the acid mist to pass through the two rows of air holes alternately, so that the alkaline purification liquid located on the upper side of the air permeable plate can fully and evenly purify the acid mist, thereby reducing repeated contact between the acid mist and a part of the alkaline purification liquid.

DETAILED DESCRIPTION

[0033] The following is combined with Figure 1 -Attached Figure 2 This application is described in further detail.

[0034] The present application embodiment discloses a chromium plating acid mist filtering device, referring to Figure 1 and Figure 2 , including a processing box 1, wherein the lower side of one side wall of the processing box 1 is connected with an air inlet pipe 11.

[0035] A horizontally arranged orifice plate 3 is provided on the upper side of the plurality of condensing tubes 2, and a plurality of through holes penetrating the orifice plate 3 are provided on the orifice plate 3. A breathable plate 4 is provided on the upper side of the orifice plate 3 and arranged in parallel with the orifice plate 3, and two rows of parallel breathable holes 41 are provided on the breathable plate 4, and each row of breathable holes 41 is provided with a plurality of breathable holes, and each row of the plurality of breathable holes 41 is evenly spaced. A single permeable membrane 42 is fixedly connected inside each breathable hole 41, and the single permeable membrane 42 is provided as a breathable membrane but can block water on one side.

[0036] The upper side of the air permeable plate 4 is provided with alkaline purification liquid.

[0037] An air outlet pipe 12 is provided on the top side wall of the processing box 1 , and the air outlet pipe 12 is arranged in the middle position of the top side wall.

[0038] When the acid mist needs to be treated, the acid mist is guided to the inside of the treatment box 1 through the air inlet pipe 11, and then the acid mist contacts with multiple condensers 2 inside the treatment box 1, so that part of the acid mist forms acid liquid after contacting the condensers 2 and flows to the bottom of the treatment box 1, and then the remaining gas passes through the orifice plate 3 and the air permeable plate 4 to contact the alkaline purification liquid, and then the treated gas is discharged from the inside of the treatment box 1 from the air outlet pipe 12 on the upper side of the treatment box 1.

[0039] By separating the acid mist into acid liquid and purified gas, on the one hand, the gas in the acid mist can be purified, and on the other hand, the acid liquid in the acid mist can be collected, thereby achieving a full treatment process for the acid mist.

[0040] A fan 5 is provided inside the processing box 1 at the lower side of the multiple condensation tubes 2, and the blowing end of the fan 5 is arranged upward. A rotating shaft 51 is fixedly connected to the lower side of the fan 5. A gas blocking hood 13 is abutted on the side of the rotating shaft 51 close to the air inlet pipe 11, and the end of the air inlet pipe 11 connected to the processing box 1 is also located inside the gas blocking hood 13. Multiple drive plates 52 are fixedly connected to the side wall of the rotating shaft 51, and the multiple drive plates 52 are evenly distributed around the rotating shaft 51, and two adjacent drive plates 52 cooperate with the rotating shaft 51 to achieve the blocking of the gas blocking hood 13 on one side inside the processing box 1.

[0041] When the acid mist enters the processing box 1 under the guidance of the air inlet pipe 11, the acid mist first enters the gas blocking hood 13, and then the acid mist drives the driving plate 52 inside the gas blocking hood 13 to rotate. The driving plate 52 drives the rotating shaft 51 to rotate during the rotation, and the rotating shaft 51 drives the fan 5 to rotate during the rotation. The fan 5 blows the acid mist removed from the gas blocking hood 13 toward the condenser 2 during the rotation, thereby realizing a rapid processing process of the acid mist. In this process, the acid mist can also be evenly blown toward the condenser 2 by the fan 5, thereby realizing a uniform condensation process of the acid mist by the condenser 2.

[0042] An air guide component 6 is provided between the orifice plate 3 and the air permeable plate 4. The air guide component 6 is used to drive the gas on the lower side of the air permeable plate 4 to alternately pass through the two rows of air permeable holes 41.

[0043] By providing the air guide assembly 6, the alkaline purification liquid on the upper side of the air permeable plate 4 can realize the alternating purification process of the gas in the acid mist, so that the purification liquid can fully purify the acid mist.

[0044] The air guide assembly 6 includes an air push plate 61 located between the orifice plate 3 and the air permeable plate 4, the upper side of the air push plate 61 slides against the lower side wall of the air permeable plate 4, the lower side of the air push plate 61 slides against the lower side wall of the orifice plate 3, and the air push plate 61 can simultaneously block any row of air holes 41.

[0045] One end of the push plate 61 passes through the processing box 1 and slides against the side wall of the processing box 1 in the horizontal direction. The push plate 61 passes through one end of the processing box 1 and is threadedly connected with a reciprocating screw 62, which is arranged horizontally. One end of the reciprocating screw 62 is fixedly connected to a driven bevel gear 63, and the lower side of the driven bevel gear 63 is meshed with a driving bevel gear 64, and the lower side of the driving bevel gear 64 is fixedly connected to a vertically arranged connecting shaft 65, and one end of the connecting shaft 65 away from the driving bevel gear 64 is fixedly connected to a driven pulley 66. A driving pulley 67 is fixedly sleeved on the rotating shaft 51, and the same connecting belt 68 is sleeved on the driving pulley 67 and the driven pulley 66.

[0046] During the rotation of the fan 5, the rotating shaft 51 drives the driving pulley 67 to rotate. During the rotation of the driving pulley 67, it can drive the driven pulley 66 to rotate through the connecting belt 68. During the rotation of the driven pulley 66, it drives the connecting shaft 65 to rotate. The connecting shaft 65 drives the driving bevel gear 64 and the driven bevel gear 63 to rotate. During the rotation of the driven bevel gear 63, it drives the reciprocating screw 62 to rotate. During the rotation of the reciprocating screw 62, it drives the push plate 61 to move back and forth. During the movement of the push plate 61, on the one hand, it can limit the gas from moving out of a certain row of air holes 41. On the other hand, it can also cooperate with the fan 5 to drive the gas to quickly pass through the single-permeable membrane 42, thereby speeding up the treatment process of the acid mist.

[0047] A guide plate 21 is fixedly connected to the lower side of each condenser tube 2, and the vertical cross-section of each guide plate 21 is triangular, and the two vertices of the triangle are fixedly connected to the condenser tube 2, and the other vertex of the triangular guide plate 21 is set downward. The extension line of the vertex of each guide plate 21 facing the lower side is located on one side of the fan 5, and the position of the bottom side wall of the processing box 1 pointed to by the extension line of the vertex of one of the guide plates 21 is penetrated and connected with the liquid outlet pipe 14.

[0048] The acid liquid condensed on the condenser 2 can flow along the guide plate 21 to the bottom of the treatment box 1 and then flow out of the treatment box 1 from the liquid outlet pipe 14. Since the extension line of the bottom end point of the guide plate 21 is located on the side of the fan 5, the influence of the acid liquid on the fan 5 can be reduced.

One end of the vibrating rod 71 away from the air pushing plate 61 passes through the orifice plate 3 and slides against the orifice plate 3 along the moving direction of the air pushing plate 61 .

[0050] During the movement of the air pushing plate 61 , the vibrating rod 71 is driven to contact the plurality of condensing tubes 2 , so that the vibrating rod 71 can accelerate the process of the acid liquid on the condensing tubes 2 being left behind.

[0051] The implementation principle of a chromium plating acid mist filtering device in an embodiment of the present application is: the acid mist is guided to the inside of the treatment box 1 through the air inlet pipe 11, and then the acid mist drives the fan 5 to rotate, and the fan 5 blows the acid mist to the condenser 2, so that the condenser 2 can condense the acid mist, and the condensed liquid flows to the liquid outlet pipe 14 along the guide plate 21, and then flows out from the liquid outlet pipe 14.

[0052] The remaining gas passes through the perforated plate 3 and is alternately moved out from the two rows of air holes 41 driven by the air push plate 61. The gas then contacts the alkaline purification liquid on the upper side of the air permeable plate 4 for purification. The purified gas passes through the outlet pipe 12 and moves out of the treatment box 1, thereby completing the treatment process of the acid mist.

[0053] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto.
