Description

Technical Field

[0001] The present invention relates to the technical field of exhaust purification, and particularly to an exhaust purification mechanism for electroless nickel reaction. Background Art

[0002] During the electroless nickel plating solution reaction process, the generation of black spots is usually related to various factors, including defects on the metal surface, redox reactions, the structure of the metal surface, and the components in the electroless nickel plating solution. In order to reduce the possibility that corrosive gases stay in the production environment for a long time, react with the metal surface, and increase the formation of black spots, a corresponding exhaust mechanism is usually set up. The exhaust mechanism can timely discharge these corrosive gases, thereby reducing the chance of their reaction with the metal surface and reducing the generation of black spots. At the same time, after the exhaust mechanism extracts the corrosive gases, it can also improve the working environment and reduce the risk of workers being exposed to harmful environments.

[0003] For example, a Chinese patent with the publication number: CN207786260U, the name: An activated carbon air purifier, and the publication date: August 31, 2018, includes a purifier body, an adsorption chamber, activated carbon packages, an exhaust fan, a blower, a detection chamber, a drying chamber, a motor, a chemical material chamber, an ion purification chamber, a water absorption chamber, water absorption cotton, an electromagnetic adsorption tube, a rotating shaft, a heating tube, and a heating pipe. The activated carbon packages are arranged inside the adsorption chamber. The exhaust fan is arranged on the lower side of the right end face of the purifier body. The blower is arranged on the upper side of the right end face of the purifier body. The detection chamber is arranged at the top end face inside the purifier body. The drying chamber is arranged below the detection chamber. The chemical material chamber is arranged below the drying chamber. The water absorption cotton is arranged inside the water absorption chamber. The electromagnetic adsorption tube is arranged inside the ion purification chamber. The left end of the rotating shaft is fixedly connected to the output end of the motor. The heating tube is fixedly installed on the rotating shaft. The heating tube is arranged inside the heating tube.

[0004] Among the above-mentioned prior arts, the following technical problems exist: When the existing air purifier treats waste gas, the activated carbon packages arranged inside are used to adsorb harmful substances in the waste gas. However, when the waste gas contacts the activated carbon packages, it is not convenient to increase the contact time between the waste gas and the activated carbon packages, resulting in the harmful substances in the waste gas being discharged before being fully adsorbed. At the same time, when the activated carbon packages are in use, it is not convenient to turn the activated carbon particles inside. When the activated carbon particles are in a static state, some areas of the activated carbon may become saturated in advance because they first come into contact with pollutants, leading to a decrease in the overall adsorption efficiency.

[0005] Therefore, we propose an exhaust purification mechanism for electroless nickel reaction to solve the problems raised in the above-mentioned prior arts. Summary of the Invention

[0042] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0043] Embodiment 1: Please refer to Figures 1-10, when the existing air purifier treats waste gas, the activated carbon package arranged inside is used to adsorb harmful substances in the waste gas. However, when the activated carbon package contacts the waste gas, it is not convenient to increase the contact time between the waste gas and the activated carbon package, resulting in the harmful substances in the waste gas being discharged before being fully adsorbed. To solve this technical problem, the following technical content is disclosed in this embodiment. A suction purification mechanism for nickel plating reaction includes a positioning seat 1. A suction port 2 is opened on the positioning seat 1, and a filter plate 3 is connected inside the positioning seat 1. The middle part of the upper end of the positioning seat 1 is interconnected with a protective cover 5 through a circulation port 4, and a suction pipe 6 is installed on the protective cover 5. A negative pressure suction fan is installed inside the suction pipe 6. An active purification component 7 for adsorbing harmful gases is installed inside the protective cover 5, and an adjustment component 8 is installed above the active purification component 7. A knocking component 9 for vibrating and dredging the filter plate 3 is arranged at the lower end of the active purification component 7. The inside of the positioning seat 1 is a hollow structure, and a plurality of suction ports 2 are evenly distributed on the positioning seat 1. And the filter plate 3 inside the positioning seat 1 is located directly below the circulation port 4. The active purification component 7 includes a fixed plate 701, and the fixed plates 701 are symmetrically distributed on the inner sides of the protective cover 5. Two movable plates 702 are arranged between the two fixed plates 701. Branch blocks 703 are fixed on both the movable plates 702 and the fixed plates 701, and connection holes 704 are opened on the branch blocks 703. Activated carbon particles are filled inside the fixed plates 701 and the movable plates 702. The inside of the fixed plates 701 and the movable plates 702 is interconnected with the inside of the branch blocks 703, and the branch blocks 703 on the fixed plates 701 and the movable plates 702 can mesh with each other. And the branch blocks 703 on the opposite sides of the two movable plates 702 can also mesh with each other. The adjustment component 8 includes a servo motor 801, and the servo motor 801 is fixed on the upper end of the positioning seat 1. A transmission lead screw 802 is fixed to the output end of the servo motor 801, and a pressure application frame 803 is threadedly connected to the transmission lead screw 802. The lower end of the pressure application frame 803 extends into the inside of the protective cover 5, and a guiding block 804 is arranged on the side of the lower end of the pressure application frame 803. The guiding block 804 is fixed to the upper end of the movable plate 702, and the guiding block 804 is installed through a guiding rod 805 fixed inside the protective cover 5. The guiding block 804 is connected to the inside of the protective cover 5 through an auxiliary spring 806. The pressure application frame 803 and the protective cover 5 are in sliding connection, and the inclined surface at the lower end of the pressure application frame 803 is in mutual fit with the inclined surface of the guiding block 804, and the guiding block 804 can slide on the guiding rod 805. The knocking component 9 includes a power magnetic block 901, and the power magnetic block 901 is fixed to the side of the lower end of the movable plate 702. A clamping magnetic block 902 is arranged on the side of the power magnetic block 901, and the clamping magnetic block 902 is fixed to the upper end of the rod body of the driving frame 903. The driving frame 903 is connected to the positioning seat 1 through a return spring 904, and a striking block 905 is fixed to the side of the driving frame 903 facing the filter plate 3.One side of the driving magnetic block 901 and the clamping magnetic block 902 at the end of the rod of the driving frame 903 are opposite in magnetism, and the striking blocks 905 evenly distributed at the lower end of the driving frame 903 are in contact with the filter plate 3 in the initial state.

[0044] When carrying out the electroless nickel reaction, turn on the negative pressure exhaust fan inside the suction pipe 6. At this time, the harmful gases in the external environment are extracted through the air extraction port 2 on the positioning seat 1. After the harmful gases enter the inside of the positioning seat 1, they first pass through the filter plate 3, and the filter plate 3 filters out the particulate dust in the harmful gases. Then the filtered harmful gases enter the inside of the protective cover 5 through the flow port 4. In the initial state, the branch block 703 on the side of the movable plate 702 meshes with the branch block 703 on the fixed plate 701, while the branch blocks 703 on the sides of adjacent movable plates 702 are disengaged from each other to form an air flow channel. The harmful gases pass through the air flow channel formed between adjacent movable plates 702. Since the branch block 703 is arranged in an isosceles trapezoid structure, the inclined surface of the branch block 703 can be used to slow down the flow speed of the harmful gases therein. The harmful gases enter the connecting hole 704 on the branch block 703 and come into contact with the activated carbon particles, and the activated carbon particles are used to further purify and adsorb the harmful gases. The purified harmful gases are discharged from the upper end of the suction pipe 6. After a period of adsorption, turn on the servo motor 801. The activation of the servo motor 801 can cause the transmission lead screw 802 to rotate. After the transmission lead screw 802 rotates, the pressing frame 803 connected by threads can move downward. After the pressing frame 803 moves downward, it can use the hypotenuse to squeeze the guiding block 804, so that the guiding block 804 and the movable plate 702 move toward the center of the protective cover 5. At this time, the branch blocks 703 on the opposite sides of the two movable plates 702 mesh with each other, while the branch blocks 703 on the opposite sides of the movable plate 702 and the fixed plate 701 are disengaged from each other to form an air flow channel. Subsequently, when the harmful gases enter, they can flow through the air flow channel formed after the branch blocks 703 on the movable plate 702 and the fixed plate 701 are disengaged. When the movable plate 702 moves toward the center of the protective cover 5, the movable plate 702 can drive the driving magnetic block 901 at the lower side of the movable plate 702 to move synchronously. When the driving magnetic block 901 moves and approaches the clamping magnetic block 902 on the driving frame 903, the magnetic attraction between the two can cause the driving frame 903 to drive the striking block 905 to move upward. When the movable plate 702 continues to move, the driving magnetic block 901 at the lower side of the movable plate 702 moves away from the clamping magnetic block 902 on the driving frame 903, and the driving frame 903 and the striking block 905 rebound under the action of the return spring 904. After resetting, the striking block 905 can impact the filter plate 3, and the vibration generated by the impact can shake off the particulate matter attached to the filter plate 3.

[0045] Embodiment 2: The technical content disclosed in this embodiment is a further improvement on the above-mentioned embodiment 1. It is not convenient to turn over the activated carbon particles inside the activated carbon bag when in use. When the activated carbon particles are in a static state, some areas of the activated carbon may be saturated prematurely because they are the first to contact the pollutants, resulting in a decrease in the overall adsorption efficiency. In order to further solve this technical problem, this embodiment discloses the following technical content: a turning component 10 for turning over the internal activated carbon particles is installed on the movable purification component 7, and the turning component 10 includes a push rod 101, and the push rod 101 is installed through the branch block 703. The end of the push rod 101 located on the inner side of the branch block 703 is connected to each other through the built-in spring 103 and the accommodating column 102, and the push rod 101 is fixed A material flipping plate 104 is installed, and a material tapping component 105 is installed on the material flipping plate 104. The material flipping plate 104 and the top rod 101 are vertically distributed, and a plurality of material tapping components 105 are evenly distributed on the material flipping plate 104. The material tapping component 105 includes a base plate 1051, and a driving rod 1052 is installed on the upper end of the base plate 1051. The driving rod 1052 is inserted into the interior of a material tapping column 1053, and the material tapping column 1053 is rotatably installed in the middle of a guide column 1057, and the guide column 1057 is fixed on the base plate 1051, and an insert block 1055 is installed on the upper side of the driving rod 1052, and the insert block 1055 is inserted into a spiral power groove 1054 opened in the interior of the material tapping column 1053, and the driving rod 1052 is connected to the base plate 1051 through an adjusting spring 1056.

[0046] Since the turnover components 10 are provided on the branch blocks 703 of both the movable plate 702 and the fixed plate 701, when the movable plate 702 moves towards the fixed plate 701, the ejector rod 101 on the branch block 703 on the side of the movable plate 702 can contact the fixed plate 701, enabling the ejector rod 101 to drive the turnover plate 104 to move synchronously. The movement of the turnover plate 104 can drive the material feeding component 105 to move synchronously. By the movement of the turnover plate 104 and the material feeding component 105, the activated carbon particles inside the movable plate 702 can be turned over. Similarly, the ejector rod 101 on the branch block 703 on the side of the fixed plate 701 can contact the movable plate 702, and thus the movement of the ejector rod 101 can also turn over the activated carbon particles inside the movable plate 702 through the turnover plate 104 and the material feeding component 105. When the two movable plates 702 move towards the center of the protective cover 5, the ejector rods 101 on the branch blocks 703 on the sides of the two movable plates 702 can contact the corresponding movable plates 702. At this time, when the two movable plates 702 move towards the center of the protective cover 5, the turnover plates 104 on the ejector rods 101 can also effectively turn over the activated carbon particles. At the same time, after the substrate 1051 moves and is squeezed, the movement of the substrate 1051 can cause the driving rod 1052 to move synchronously. After the driving rod 1052 moves, the insertion block 1055 on the side of the end can move in the spiral power groove 1054 inside the material feeding column 1053, thereby enabling the material feeding column 1053 to rotate. By the rotation of the material feeding column 1053, the activated carbon particles can be turned over. The movement of the turnover plate 104 driving the material feeding component 105 and the rotation of the material feeding column 1053 can effectively improve the turnover effect of the activated carbon particles.

[0047] The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
