Description

Technical Field

[0001] The present invention relates to the technical field of high-valent arsenic coating, and particularly to a surface coating device for processing high-valent arsenic. Background Art

[0002] High-valent arsenic can be used as a fining agent to remove bubbles during the production of photovoltaic glass, thereby improving the light transmittance of the glass. High light transmittance plays a decisive role in enhancing the solar energy conversion efficiency. However, due to its highly toxic nature, dust leakage is likely to occur during use, leading to serious environmental pollution and health risks. Therefore, it is necessary to coat its surface with a silane film, which can improve its bulk fluidity and meet the qualified water immersion toxicity index, while not affecting its use effect.

[0003] The silane film coating of high-valent arsenic mainly includes: solvothermal method, gas-phase reaction method, and hydrolysis and condensation method; since the solvothermal method has a relatively cumbersome process and the coating layer obtained by the gas-phase reaction method has poor dispersibility, the hydrolysis and condensation method is often used as the method for coating high-valent arsenic with a silane film, which is not only simple to operate but also low in cost.

[0004] Currently, when high-valent arsenic is subjected to hydrolysis and condensation coating, the solution needs to be first heated to an appropriate temperature and stirred to ensure that the reactants are fully mixed, while controlling the feeding speed and amount of high-valent arsenic; however, in the prior art, it is difficult to achieve a comprehensive homogeneous stirring of the solution and high-valent arsenic during the stirring of the solution, which affects the homogenization efficiency and coating quality; moreover, the feeding speed and amount of high-valent arsenic are manually controlled, which is prone to situations such as too fast, too slow, and too much feeding, which may affect the coating efficiency, as well as the situation of reaction out of control or uneven products. Summary of the Invention

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with 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.

[0023] In the description of the present invention, it should be understood that the orientation or positional relationships indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. are based on the orientation or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present invention.

[0024] Embodiment: Referring to Figures 1 - 7 , a surface coating device for high-valent arsenic processing, including a stirring tank 1 and a bracket 2, further including: a driving motor 3 fixedly connected to the bracket 2, the output end of the driving motor 3 is connected to a rotating shaft 4, wherein, a multi-directional stirring mechanism is arranged on the rotating shaft 4 for stirring the bottom, side wall and middle position of the stirring tank 1, and the middle position can move up or down along the rotating shaft 4; a feeding member 25 arranged on the multi-directional stirring mechanism, a linkage mechanism 26 is arranged between the feeding member 25 and the rotating shaft 4 for feeding the feeding member 25 according to the stirring speed, wherein, a material blocking assembly is arranged on the feeding member 25, and the linkage assembly and the material blocking assembly are connected to the multi-directional stirring mechanism through pipelines.

[0025] Referring to Figures 2 - 4 , the multi-directional stirring mechanism includes a chassis 5 fixedly connected to the bottom end of the rotating shaft 4, a plurality of spiral plates 6 are fixedly connected to the chassis 5, the upper and lower parts of the inner wall of the stirring tank 1 are both connected with slide rails 15, a rotating ring 16 is slidably connected inside the slide rails 15, a plurality of fixing rods 17 are fixedly connected between the rotating ring 16 at the bottom and the rotating shaft 4, and a plurality of side plates 18 are fixedly connected between the two rotating rings 16. Among them, the chassis 5 is located at the bottom of the stirring tank 1 and matches the size of the stirring tank 1, the spiral plates 6 are evenly distributed above the chassis 5, and the rotating ring 16 and the fixing rods 17 at the bottom are located above the spiral plates 6.

[0026] It should be explained that a plurality of holes are arranged on the surface of the chassis 5, the aperture of which is smaller than the size of high-valent arsenic, and only the solution can pass through. When the spiral plates 6 rotate, the solution will be conveyed upward, so as to continuously convey the high-valent arsenic near the bottom upward, avoiding the accumulation of high-valent arsenic at the bottom of the stirring tank 1. During the stirring process, the high-valent arsenic flowing towards the side wall of the stirring tank 1 can flow towards the middle position of the stirring tank 1 under the action of the side plates 18, thereby improving the homogenization efficiency and quality of the high-valent arsenic and the solution.

[0027] Referring toFigures 2 - 3 It also includes a fixing ring 7 fixedly connected to the rotating shaft 4. A first spring 11 is fixedly connected to the fixing ring 7. A first stirring plate 8 connected to the first spring 11 is slidably connected to the rotating shaft 4. A second stirring plate 9 is slidably connected to the rotating shaft 4. A plurality of limiting strips 10 penetrating through the first stirring plate 8 and the second stirring plate 9 are fixedly connected to the rotating shaft 4. Among them, the fixing ring 7 is located above the fixing rod 17, the second stirring plate 9 is located above the first stirring plate 8. Holes matching the limiting strips 10 are formed in both the first stirring plate 8 and the second stirring plate 9. An adjusting assembly is arranged between the first stirring plate 8 and the second stirring plate 9.

[0028] Here, the shapes and numbers of the first stirring plate 8 and the second stirring plate 9 are not limited, and the staff can adjust them according to the situation. When the rotating shaft 4 rotates, under the action of the limiting strips 10, the first stirring plate 8 and the second stirring plate 9 can rotate synchronously with the rotation, stirring the solution and the high-valent arsenic. And during the stirring process, due to the continuous addition of high-valent arsenic, the forces received by the first stirring plate 8 and the second stirring plate 9 change continuously during the rotation. Under the action of the first spring 11, the first stirring plate 8 and the second stirring plate 9 can move upward or downward along the rotating shaft 4, making the flow direction of the high-valent arsenic in the solution irregular, thereby improving the homogenization effect of the high-valent arsenic and the solution.

[0029] Refer to Figure 3 The adjusting assembly includes connecting rods 12 symmetrically hinged to the side of the first stirring plate 8 and the second stirring plate 9 close to each other. The ends of the connecting rods 12 on the same side of the first stirring plate 8 and the second stirring plate 9 are rotatably connected. A first hydraulic rod 13 is hinged between two groups of connecting rods 12 on the same side.

[0030] Refer to Figure 3 and Figure 5 It also includes an installation groove 19 formed in the second stirring plate 9. An extrusion block 20 is rotatably connected to the inside of the installation groove 19. A plurality of second hydraulic rods 21 and second springs 22 are fixedly connected to one side of the installation groove 19 close to the extrusion block 20. Among them, the extrusion block 20 is inclined. The second spring 22 is sleeved on the second hydraulic rod 21, and the end of the second spring 22 away from the installation groove 19 is connected to the second hydraulic rod 21. A connecting pipe 23 is communicated with a plurality of second hydraulic rods 21, and the connecting pipe 23 penetrates into the inside of the second stirring plate 9.

[0031] During the stirring process, when continuously adding high-valent arsenic, the density of the solution also continuously increases, and the resistance received by the first stirring plate 8 and the second stirring plate 9 on the side close to the rotation direction also increases. That is, the more the addition amount of high-valent arsenic, the greater the resistance received by the first stirring plate 8 and the second stirring plate 9 during rotation. This resistance acts on the extrusion block 20, driving the extrusion block 20 to rotate into the installation groove 19. Moreover, the larger the angle at which the extrusion block 20 rotates into the installation groove 19, the greater the resistance it receives, and the larger the addition amount of high-valent arsenic. Thus, the addition amount of high-valent arsenic in the stirring tank 1 can be monitored to facilitate controlling the subsequent addition amount and addition speed of high-valent arsenic.

[0032] Refer to Figure 3 , a slip ring 24 is rotatably connected to the rotating shaft 4. A groove 14 is formed on the side of the rotating shaft 4 close to the connecting rod 12. The first hydraulic rod 13 and the slip ring 24 are connected through a pipeline, and the pipeline passes through the groove 14 into the rotating shaft 4, and the connecting pipe 23 is connected to the slip ring 24.

[0033] The specific structure of the slip ring 24 can refer to the technical solutions in the prior art. Those skilled in the art can know this and will not be elaborated here. The slip ring 24 is used to ensure the stability of gas or hydraulic transmission when the device rotates. It should be explained that during the transmission process of the first hydraulic rod 13 and the slip ring 24 and the connecting pipe 23 and the slip ring 24, there will be no crossing situation. The groove 14 is used to ensure the stability of the pipeline connection when the first stirring plate 8 and the second stirring plate 9 move upward or downward.

[0034] Refer to Figure 2 and Figure 6 , the linkage mechanism 26 includes a worm 261 fixedly connected to the rotating shaft 4. A mounting frame 262 is fixedly connected to the side of the slide rail 15 close to the worm 261. A reciprocating lead screw 263 is rotatably connected to the mounting frame 262. A worm gear 264 meshing with the worm 261 is fixedly connected to the end of the reciprocating lead screw 263. Bevel gear sets 32 that mesh with each other are rotatably connected to the sides of the mounting frame 262 and the feeding member 25 that are close to each other, and the bevel gear sets 32 are connected to the end of the reciprocating lead screw 263.

[0035] The meshing method between the worm 261 and the worm gear 264 is a conventional means in the prior art, so it will not be elaborated here. It should be explained that the thread direction on the surface of the worm 261 can be adjusted according to the actual situation so that when it drives the reciprocating lead screw 263 to rotate and drives the feeding disk 31 to rotate through the bevel gear sets 32, the high-valent arsenic in the feeding member 25 can be conveyed along the feeding disk 31 to the side of the stirring tank 1.

[0036] Refer to Figure 6 and Figure 7, it further includes a feeding tray 31 rotatably connected within the feeding member 25. The outer wall of the feeding tray 31 fits against the inner wall of the feeding member 25, and the shaft end of the feeding tray 31 is connected to the bevel gear set 32.

[0037] When the feeding tray 31 stops rotating, it can block the high-valent arsenic within the feeding member 25, preventing the continuous addition of high-valent arsenic after the equipment stops running. When the feeding tray 31 rotates, first, the high-valent arsenic within the feeding member 25 fills between the plates on the surface of the feeding tray 31 under the action of gravity. As the feeding tray 31 rotates, the high-valent arsenic between the plates can be transported to the other side of the feeding tray 31, and finally, it will fall into the stirring tank 1 under the action of gravity, thus realizing the automatic addition of high-valent arsenic.

[0038] Refer to Figure 7 , the baffle assembly includes a sealing block 27 fixedly connected to the feeding member 25. A sealing groove 28 communicating with the feeding member 25 is formed inside the sealing block 27. A third spring 29 is fixedly connected inside the sealing groove 28. The end of the third spring 29 is fixedly connected to an adjusting baffle 30 that fits tightly against the sealing groove 28. Among them, the sealing groove 28 communicates with the connecting pipe 23 through a pipeline and a slip ring 24, and the adjusting baffle 30 fits against the feeding tray 31.

[0039] Initially, the adjusting baffle 30 does not affect the feeding of high-valent arsenic by the feeding tray 31. When the high-valent arsenic in the stirring tank 1 reaches a certain amount, the resistance received by the extrusion block 20 during the rotation of the second stirring plate 9 increases, driving the extrusion block 20 to rotate into the installation groove 19. At the same time, the second hydraulic rod 21 is compressed, and the hydraulic pressure is transmitted to the sealing groove 28 through the pipeline and the slip ring 24, driving the adjusting baffle 30 to move into the feeding member 25, thereby reducing the single-time feeding amount of high-valent arsenic by the feeding tray 31, adjusting the addition speed of high-valent arsenic, ensuring more complete homogenization of high-valent arsenic and the solution in the stirring tank 1. When the high-valent arsenic in the stirring tank 1 reaches the threshold value, the second hydraulic rod 21 drives the adjusting baffle 30 to fit against the inner wall of the feeding member 25, stopping the addition of high-valent arsenic, achieving the purpose of automatically controlling the addition amount of high-valent arsenic, and preventing the situation of uneven products caused by excessive addition amount of high-valent arsenic.

[0040] Refer to Figure 6 , it further includes a slider 265 arranged on the reciprocating lead screw 263. A third hydraulic rod 266 is connected between the slider 265 and the mounting bracket 262. The third hydraulic rod 266 communicates with the first hydraulic rod 13 through a pipeline and a slip ring 24.

[0041] The interior of the slider 265 is provided with a convex block that matches the reciprocating lead screw 263. This is a conventional means in the prior art, so it will not be elaborated here. When the rotating shaft 4 drives the worm 261 to rotate, the reciprocating lead screw 263 is driven to rotate through the worm gear 264. During the rotation of the reciprocating lead screw 263, the third hydraulic rod 266 can limit the slider 265, causing the slider 265 to reciprocate along the reciprocating lead screw 263, thereby intermittently compressing the third hydraulic rod 266. The hydraulic pressure is intermittently conveyed into the first hydraulic rod 13 through a pipeline and a slip ring 24. During the extension and contraction of the first hydraulic rod 13, the connecting rod 12 is driven to rotate relatively or in opposite directions, thereby adjusting the distance between the first stirring plate 8 and the second stirring plate 9, further improving the homogenization efficiency and quality between the high-valent arsenic and the solution. Additionally, the installation direction of the third hydraulic rod 266 is not limited. It can be located on the side of the slider 265 close to the worm gear 264 or on the side of the slider 265 close to the feeding member 25.

[0042] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes should be covered within the protection scope of the present invention.
