Specific embodiments

[0030] 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. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] Please refer to Figures 1 to 10, the present invention provides a technical solution: a mixing device for producing a polymer defoamer, which includes an outer barrel body 3 and an inner barrel body 31. There is a gap between the outer barrel body 3 and the inner barrel body 31, and a spiral heating sheet 14 is arranged in the gap. A heating control component 15 connected to the spiral heating sheet 14 is arranged on the outer barrel body 3. The heating control component 15 is a publicly known prior art. A top cover 4 and a bottom plate 17 are arranged on the outer barrel body 3. A fixed column 9 is arranged on the top cover 4, and a feed pipe 6 for feeding materials is arranged inside the fixed column 9. A scraping plate 8 for scraping the inner wall of the inner barrel body 31 is arranged inside the inner barrel body 31. A mixing mechanism is arranged inside the inner barrel body 31. The mixing mechanism includes a driving component 5, a stirring component 7, a bottom mixing component 11, and a vibration mixing component 13. The driving component 5 is arranged on the top cover 4 to provide power. The stirring component 7 is arranged inside the inner barrel body 31 to stir and mix the liquid. The bottom mixing component 11 is arranged inside the inner barrel body 31 below the stirring component 7. The bottom mixing component 11 is used to mix the bottom inside the inner barrel body 31. The vibration mixing component 13 is arranged on the bottom plate 17 to vibrate and mix the bottom sediment. By arranging the stirring component 7 and the scraping plate 8, the spiral stirring blade 73 rotates around its own axis during rotation, stirring the materials more quickly, thus improving the mixing efficiency. The scraping plate 8 scrapes the inner wall of the inner barrel body 31 to prevent the adhesion of materials on the inner wall of the inner barrel body 31. Through the cooperation of the bottom mixing component 11 and the vibration mixing component 13, the first magnetic plate 136 and the second magnetic plate 137 are arranged with the same-named magnetic poles facing each other. The mounting column 133 falls onto the bottom plate 17 to achieve the vibration effect, causing the bottom sediment to vibrate and preventing the sediment from accumulating. At the same time, the vibrating sediment is stirred by the mixing blade 117 to achieve rapid mixing, thereby improving the production efficiency.

[0032] Turn on the motor 20, drive the connecting gear 19 to drive the rotating gear 18 to rotate on the fixed column 9, and then drive the feed pipe 6 to move downward in the fixed column 9, open the sealing cover on the feed pipe 6, and sequentially add the mixed materials into the inner barrel body 31 from the feed pipe 6. Close the sealing cover, start the driving motor 51, and the driving motor 51 drives the middle gear 53 to rotate on the fixed column 9 through the driving gear 52. Since the stirring gear 71 meshes with the internal gear ring 74, the stirring gear 71 rotates under the drive of the middle gear 53 and rotates around its own axis along the internal gear ring 74 during this process, and drives the spiral stirring blade 73 to stir and mix the materials through the connecting rod 72.

[0033] An installation ring 2 and a plurality of support legs 1 located on the installation ring 2 are fixedly installed on the outer barrel body 3. The plurality of support legs 1 ensure the stability of the device. A rotating gear 18 is rotatably connected to the fixed column 9. The lower end of the feed pipe 6 passes through the rotating gear 18 and the fixed column 9 and extends into the inner barrel body 31. A ventilation pipe 16 and a motor 20 are provided on the top cover 4. The ventilation pipe 16 is used for ventilation to ensure the stability of the pressure inside the inner barrel body 31. A connecting gear 19 meshing with the rotating gear 18 is installed on the motor 20, and the rotating gear 18 is driven to rotate by the connecting gear 19.

[0034] Through the cooperation of the bottom mixing assembly 11 and the vibration mixing assembly 13, the first magnetic plate 136 and the second magnetic plate 137 are arranged with the same-named magnetic poles facing each other. The mounting column 133 falls onto the bottom plate 17 to achieve the vibration effect, causing the bottom sediment to vibrate and preventing the sediment from accumulating. At the same time, the vibrating sediment is stirred by the mixing blades 117 to achieve rapid mixing, thereby improving the production efficiency. By providing the stirring assembly 7 and the scraper 8, the spiral stirring blades 73 rotate during rotation, stirring the material more quickly and improving the mixing efficiency. The inner wall of the inner barrel body 31 is scraped by the scraper 8 to prevent the material from adhering to the inner wall of the inner barrel body 31.

[0035] The feed pipe 6 is threadedly connected to the rotating gear 18, and the strengthening liquid material is sequentially added into the inner barrel body 31 from the feed pipe 6. The feed pipe 6 can reduce the material splash. The driving assembly 5 includes a driving motor 51, a driving gear 52, and a middle gear 53. The driving motor 51 is fixedly installed on the top cover 4 through a mounting frame. The output end of the driving motor 51 passes through the top cover 4 and is fixedly connected to the driving gear 52. The middle gear 53 is rotatably installed on the fixed column 9 and meshes with the driving gear 52. The driving motor 51 provides power to the middle gear 53 through the driving gear 52.

[0036] By starting the motor 20, the driving connecting gear 19 drives the rotating gear 18 to rotate on the fixed column 9, and then drives the feed pipe 6 to move downward in the fixed column 9, opening the sealing cover on the feed pipe 6. The mixed material is sequentially added into the inner barrel body 31 from the feed pipe 6, and the sealing cover is closed. By adjusting the height of the feed pipe 6 inside the inner barrel body 31, it is beneficial to reduce the material splash during the feeding process, avoid the material splashing to the lower end of the bottom plate 17 during the feeding process, which is not convenient for cleaning, and at the same time reduce the evaporation of a small amount of liquid splashing onto the inner wall of the heated inner barrel body 31 during the intermediate feeding, improving the accuracy of the material ratio and the production quality.

[0037] The stirring assembly 7 includes a stirring gear 71, a connecting rod 72, a spiral stirring blade 73, and an internal gear ring 74. The stirring gear 71 is rotatably connected to the lower end of the middle gear 53. The internal gear ring 74 is fixedly installed on the inner wall of the inner barrel body 31. The stirring gear 71 meshes with the internal gear ring 74. The connecting rod 72 is connected to the lower end of the stirring gear 71. The spiral stirring blade 73 is fixedly installed on the connecting rod 72. A plurality of connecting long plates 10 are fixedly installed at the lower end of the internal gear ring 74. Since the stirring gear 71 meshes with the internal gear ring 74, the stirring gear 71 rotates driven by the middle gear 53 and rotates around its own axis along the internal gear ring 74 during this process. The spiral stirring blade 73 is driven by the connecting rod 72 to stir and mix the materials.

[0038] The fixing column 9 is fixedly installed in the middle of the top cover 4. The scraping plate 8 is fixedly installed on the connecting long plate 10. The scraping plate 8 abuts against the inner wall of the inner barrel body 31. The scraping plate 8 is used to scrape the inner wall of the inner barrel body 31. The spiral heating sheet 14 is closely attached to the inner barrel body 31. The spiral heating sheet 14 is arranged in a sheet shape. The contact area between the spiral heating sheet 14 and the inner barrel body 31 is large, and the heating effect is good. A sealing cover is provided on the feed pipe 6, and a liquid outlet is provided on the bottom plate 17, which is convenient for discharging the mixed materials.

[0039] The bottom mixing assembly 11 includes an internal gear ring 111, a mixing gear 112, a first bevel gear 113, a second bevel gear 114, a rotating rod 115, a rotating column 116, and mixing blades 117. The internal gear ring 111 is fixedly installed inside the inner barrel body 31. The rotating column 116 is rotatably connected to the connecting long plate 10. The mixing blades 117 are fixedly installed on the rotating column 116. The rotating rod 115 is rotatably connected to one end of the connecting long plate 10 through a connecting frame. The second bevel gear 114 is fixedly connected to one end of the rotating column 116. The first bevel gear 113 is fixedly installed on the rotating rod 115 and meshes with the second bevel gear 114. The mixing gear 112 is fixedly installed on the rotating rod 115 and meshes with the internal gear ring 111. When the connecting long plate 10 drives the mixing gear 112 to move on the internal gear ring 111 through the connecting frame, the mixing gear 112 rotates around its own axis. Then, the second bevel gear 114 is driven to rotate by the rotating rod 115 and the first bevel gear 113. The second bevel gear 114 drives the mixing blades 117 to rotate through the rotating column 116.

[0040] A bottom ring body 12 is fixedly installed at the lower end of the connecting long plate 10. There are multiple sets of vibration mixing components 13, and the multiple sets of vibration mixing components 13 are arranged in an annular array between the bottom ring body 12 and the bottom plate 17. The vibration mixing component 13 includes a fixed block 131, a connecting column 132, a mounting column 133, a spring 134, a mounting plate 135, a first magnetic plate 136, and a second magnetic plate 137. As the bottom ring body 12 continues to rotate, the first magnetic plate 136 moves away from above the second magnetic plate 137, and the repulsive force disappears. Under the action of the spring 134, the spring 134 drives the mounting column 133, the mounting plate 135, and the first magnetic plate 136 to fall onto the bottom plate 17, achieving the vibration effect, causing the bottom sediment to be mixed. During this process, when the connecting long plate 10 drives the mixing gear 112 to move on the internal gear ring 111 through the connecting frame, it rotates itself, and then drives the second bevel gear 114 to rotate through the rotating rod 115 and the first bevel gear 113. The second bevel gear 114 drives the mixing blade 117 to rotate through the rotating column 116. The rotation of the mixing blade 117 facilitates the stirring and mixing of the sediment vibrated at the bottom. The first magnetic plate 136 and the second magnetic plate 137 are arranged with the same-named magnetic poles facing each other. When the mounting column 133 falls onto the bottom plate 17, the vibration effect is achieved, causing the bottom sediment to vibrate and preventing the sediment from piling up. At the same time, the vibrated sediment is stirred by the mixing blade 117, achieving rapid mixing, thereby improving the production efficiency.

[0041] The fixed block 131 is fixedly installed at the upper end of the bottom plate 17, the second magnetic plate 137 is fixedly installed on the fixed block 131, the connecting column 132 is rotatably connected to the bottom ring body 12, the mounting column 133 is fixedly connected to the connecting column 132 through a connecting plate, the mounting column 133 is fixedly connected to the bottom ring body 12 through a spring 134, the first magnetic plate 136 is fixedly connected to the lower end of the mounting column 133 through the mounting plate 135, and the first magnetic plate 136 and the second magnetic plate 137 are arranged with the same-named magnetic poles facing each other. Due to the first magnetic plate 136 and the second magnetic plate 137 being arranged with the same-named magnetic poles facing each other, when the first magnetic plate 136 moves above the second magnetic plate 137, under the repulsive force between the first magnetic plate 136 and the second magnetic plate 137, it drives the mounting column 133 to compress the spring 134. As the bottom ring body 12 continues to rotate, the first magnetic plate 136 moves away from above the second magnetic plate 137, and the repulsive force disappears. Under the action of the spring 134, the spring 134 drives the mounting column 133, the mounting plate 135, and the first magnetic plate 136 to fall onto the bottom plate 17, achieving the vibration effect, causing the sediment to vibrate and accelerating the mixing.

[0042] When the present invention is in use, first, the motor 20 is started to drive the connecting gear 19 to drive the rotating gear 18 to rotate on the fixed column 9, thereby driving the feed pipe 6 to move downward in the fixed column 9, opening the sealing cover on the feed pipe 6, and sequentially adding the mixed material into the inner barrel body 31 from the feed pipe 6. Then the sealing cover is closed, and the driving motor 51 is started. The driving motor 51 drives the middle gear 53 to rotate on the fixed column 9 through the driving gear 52. Since the stirring gear 71 meshes with the internal gear ring 74, the stirring gear 71 rotates driven by the middle gear 53 and rotates around its own axis along the internal gear ring 74 during this process. The spiral stirring blade 73 is driven by the connecting rod 72 to stir and mix the materials. The middle gear 53 drives the bottom ring body 12 to rotate through the connecting long plate 10. Since the first magnetic plate 136 and the second magnetic plate 137 are arranged with the same-named magnetic poles facing each other, when the first magnetic plate 136 moves above the second magnetic plate 137, under the repulsive force between the first magnetic plate 136 and the second magnetic plate 137, the mounting column 133 is driven to compress the spring 134. The bottom ring body 12 continues to rotate, and the first magnetic plate 136 moves away from above the second magnetic plate 137, and the repulsive force disappears. Under the action of the spring 134, the spring 134 drives the mounting column 133, the mounting plate 135 and the first magnetic plate 136 to fall onto the bottom plate 17, achieving the vibration effect, so that the bottom sediment is mixed. During this process, when the connecting long plate 10 drives the mixing gear 112 to move on the internal gear ring 111 through the connecting frame, the mixing gear 112 rotates around its own axis. Then, the second bevel gear 114 is driven to rotate through the rotating rod 115 and the first bevel gear 113. The second bevel gear 114 drives the mixing blade 117 to rotate through the rotating column 116. The rotation of the mixing blade 117 facilitates the stirring and mixing of the sediment vibrated at the bottom, making the mixing effect better, saving the mixing time and improving the working efficiency.
