[0014] Preferably, an outer wall of the branch pipe is movably connected to a side of the corresponding exhaust hole with an arc-shaped plate blade, and a stirring rod is fixedly connected to the top of the arc-shaped plate blade.

[0015] The present invention provides a wastewater treatment device for a circuit board copper plating process. It has the following beneficial effects: 1. The wastewater treatment device for the copper plating process of the circuit board will push the water upward through the rotation of the outer spiral plate, causing the wastewater inside the support frame to rotate as a whole. The rotation of the outer spiral plate will cause the solids to move upward along the outer spiral plate to the top of the linkage plate. The centrifugal barrier plate allows the solid matter to move to the top of the filter plate. The centrifugal barrier plate continuously feeds the solids into the filter plate and pushes the solids fed in the previous step to the sweeping rack. The sweeping rack will sweep the solid matter outward and let it fall into the collection frame for collection. By separating the solid matter in the regulating tank, the wastewater treatment efficiency can be improved.

[0016] 2. The circuit board copper plating process wastewater treatment device pushes the water in the center of the regulating tank downward through the inner spiral plate and stirs the water. The rotation of the outer spiral plate will make the water at the edge of the regulating tank move upward and stir the water, so as to continuously turn over the water inside the regulating tank and stir the water, so that the wastewater inside the regulating tank is mixed more evenly, thereby improving the wastewater treatment efficiency.

[0017] 3. The wastewater treatment device for the copper plating process of the circuit board uses a blower to blow the outside air into the main rotating rod, and discharges it into the wastewater inside the regulating tank through the exhaust holes on the branch pipe. The air discharged from the exhaust holes will flow to the arc-shaped plate blades, allowing the arc-shaped plate blades to drive the stirring rod to rotate, so that the upward moving air becomes dispersed, increasing the contact area between the air and the wastewater. When the bubbles generated in the process rise in the wastewater, they will drive the flow and mixing of the wastewater, so that the wastewater is mixed more evenly, which can improve the treatment of the wastewater.

[0018] 4. The wastewater treatment device for the copper plating process of the circuit board, when the outside air is blown into the inside of the main rotating rod by the fan, will allow the airflow to pass through the electric heating tube and be heated by the electric heating tube. The air guide spiral plate will increase the heating time of the gas. After the gas is heated, the volume of the gas will increase, thereby making the stirring effect of other gases in the upward movement of the wastewater better. At the same time, the heated gas can heat the metal in the wastewater, make the molecules in the wastewater active, increase the subsequent treatment efficiency, and thus improve the treatment efficiency of the wastewater.

[0019] 5. The circuit board copper plating process wastewater treatment device rotates together with the branch pipe through the main rotating rod, so that the blown air and water can fully contact each other, and the branch pipe will push the water flow on one side when being driven. This water flow will make the arc-shaped blades rotate, further increasing the effect of the stirring rod rotation to break up the rising bubbles and increase the contact area between air and water. At the same time, the inner spiral plate and the outer spiral plate stir the wastewater, so that the flow inside the regulating tank can promote the uniform increase of the water temperature inside the wastewater, which can improve the wastewater treatment efficiency.

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described 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] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but are not to be construed as limiting the present invention.

[0024] Example 1: Please refer to Figure 1-5 The present invention provides a technical solution: a circuit board copper plating process wastewater treatment device, comprising a regulating tank 1, a support frame 2 is fixedly connected to the bottom of the regulating tank 1, a stirring mechanism 3 is fixedly connected inside the support frame 2, and a pneumatic component 4 is fixedly connected inside the stirring mechanism 3; The stirring mechanism 3 includes: A stirring motor 301 is fixedly connected to the bottom of the regulating tank 1; A main rotating rod 302, which is fixedly connected to the top of the stirring motor 301 and is fixedly connected to the output shaft of the stirring motor 301; The linkage plate 303 is fixedly connected to the outer wall of the main rotating rod 302.

[0025] Two outer spiral plates 304 are fixedly connected to the bottom of the linkage plate 303 , and three inner spiral plates 312 are fixedly connected to the outer wall of the main rotating rod 302 .

[0026] A water leakage hole 305 is provided on the outer wall of the outer spiral plate 304 near the linkage plate 303 , and a centrifugal blocking plate 306 is fixedly connected to the top of the linkage plate 303 at the corresponding positions of the two outer spiral plates 304 .

[0027] Two static filter bins 307 are fixedly connected to the outer wall of the regulating tank 1 , and the positions of the two static filter bins 307 on the outer wall of the regulating tank 1 correspond to the linkage plates 303 respectively.

[0028] The static filter bins 307 are fixedly connected with filter plates 308 . The outer wall of the regulating tank 1 is provided with openings at the bottom of the two linkage plates 303 to communicate with the static filter bins 307 . The top surface of the linkage plate 303 is higher than the top surface of the filter plate 308 .

[0029] The outer wall of the static filter chamber 307 is fixedly connected to a sweeping motor 310, the outer wall of the stirring motor 301 is located inside the static filter chamber 307 and is fixedly connected to a sweeping frame 309, and the sweeping frame 309 is fixedly connected to the output shaft of the sweeping motor 310, and the outer wall of the regulating tank 1 is located at the bottom of the static filter chamber 307 and is fixedly connected to a collection frame 311.

[0030] When in use, the wastewater is introduced into the regulating tank 1, and the water level of the water is lower than the leakage hole 305. At this time, the stirring motor 301 is started, and the stirring motor 301 will drive the linkage plate 303 to rotate. The rotation of the linkage plate 303 will cause the corresponding outer spiral plate 304 to rotate, and the water inside the regulating tank 1 will be pushed upward. At the same time, the inner spiral plate 312 will be driven by the main rotating rod 302 to rotate, and the wastewater inside the support frame 2 will rotate as a whole. Under the action of centrifugal force, the solid matter in the wastewater will move to the edge of the inside of the regulating tank 1. The outer spiral plate 304 will push the solid matter upward when it rotates, and the liquid pushed upward together will be in the leakage hole 305. After falling out, the solids will move upward along the outer spiral plate 304 to the top of the linkage plate 303 and be blocked by the centrifugal blocking plate 306. Under the push of the centrifugal blocking plate 306, the centrifugal force will make the solid matter move to the top of the filter plate 308. At the top of the filter plate 308, the wastewater attached to the solid matter will slowly flow back to the inside of the support frame 2 through the static filter bin 307. The centrifugal blocking plate 306 continuously feeds the solids into the filter plate 308, and will push the solids fed in the previous step to the sweeping frame 309. The sweeping frame 309 will be driven to rotate by the sweeping motor 310, which will sweep the solid matter to the outside and let it fall into the collection frame 311 for collection.

[0031] When the inner spiral plate 312 rotates, it will push the water at the center of the regulating tank 1 downward and stir the water. The rotation of the outer spiral plate 304 will make the water at the edge of the regulating tank 1 move upward and stir the water. This will continuously turn over the water inside the regulating tank 1 and stir the water, making the wastewater inside the regulating tank 1 more evenly mixed.

[0032] Example 2: Please refer to Figure 1-8 Based on the first embodiment, the present invention provides a technical solution: The pneumatic assembly 4 includes a blower 401 , which is fixedly connected to the top of the main rotating rod 302 . Three branch pipes 402 are fixedly connected to the outer wall of the main rotating rod 302 at the bottom of the inner spiral plate 312 .

[0033] Three exhaust holes 405 are provided on the outer wall of the branch pipe 402. The branch pipe 402 is connected to the inner cavity of the blower 401. An air guide block 408 is fixedly connected to the bottom of the main rotating rod 302. The air guide block 408 plays the role of guiding air to reduce the wind resistance of the airflow flowing from the main rotating rod 302 into the branch pipe 402.

[0034] An electric heating tube 403 is provided inside the main rotating rod 302, and an air guide spiral plate 404 is fixedly connected to the outer wall of the electric heating tube 403, and the air guide spiral plate 404 is fixedly connected to the inner wall of the main rotating rod 302. The electric heating tube 403 can heat the air flow passing through.

[0035] An arc-shaped plate blade 406 is movably connected to the outer wall of the branch pipe 402 at one side corresponding to the exhaust hole 405 , and a stirring rod 407 is fixedly connected to the top of the arc-shaped plate blade 406 .

[0036] When in use, start the blower 401, and the blower 401 will blow the outside air into the main rotating rod 302, and discharge it into the wastewater inside the regulating tank 1 through the exhaust hole 405 on the branch pipe 402. The air discharged from the exhaust hole 405 will flow to the arc-shaped plate blade 406. Since the two sides of the arc-shaped plate blade 406 are pushed differently, the arc-shaped plate blade 406 will drive the stirring rod 407 to rotate, so that the upward moving air becomes dispersed, increasing the contact area between the air and the wastewater. The blown air can transfer oxygen to the wastewater, and react with harmful substances in the wastewater such as reducing pollutants such as hydrogen sulfide, iron, manganese, and organic pollutants to oxidize them, converting them into harmless or easy-to-handle substances, helping to reduce the toxicity of the wastewater and improve the biodegradability of the wastewater. When the bubbles generated in the process rise in the wastewater, they will drive the flow and mixing of the wastewater, so that the wastewater can be mixed more evenly.

[0037] When the blower 401 blows the outside air into the main rotating rod 302, the air flow will pass through the electric heating tube 403 and will be heated by the electric heating tube 403. The air guide spiral plate 404 will allow the air flow passing through the electric heating tube 403 to flow in a spiral path, thereby increasing the gas heating time. After the gas is heated, the volume of the gas will increase, which will make the stirring effect in the upward movement of the wastewater better. At the same time, the heated gas can heat the metal in the wastewater, make the molecules in the wastewater active, and increase the subsequent treatment efficiency.

[0038] When the main rotating rod 302 rotates, it will rotate with the branch pipe 402, which can further promote the full contact between the blown air and the water, and when the branch pipe 402 is driven, it will allow one side of the electric branch pipe 402 to push the water flow. This water flow will act on the arc plate blade 406 to rotate the arc plate blade 406, further increasing the effect of the rotation of the stirring rod 407 to break up the rising bubbles and increase the contact area between the air and the water. At the same time, the inner spiral plate 312 and the outer spiral plate 304 stir the wastewater, allowing the flow inside the regulating tank 1 to promote the uniform increase of the water temperature inside the wastewater.

[0039] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
