Abstract
Description
Technical Field
[0001] This utility model relates to a reaction vessel, specifically a novel aerated polymerization reaction vessel. Background Technology
[0002] Reactors are typically used to produce electronic pastes. Raw materials are added to the reactor through the feed port. The reactor is connected to an aeration pipe. After the raw materials are added, the aeration pipe and drive device are turned on. The aeration pipe aerates the reactor, and the raw materials and gas undergo a chemical reaction inside the reactor. The drive device drives the stirring rod to mix the gas and raw materials, reducing the production time of the product.
[0003] In practical use, the inventors discovered that the current reaction vessel still has shortcomings, specifically:
[0004] Currently, aeration pipes in reactors are typically connected to the bottom or top of the reactor. Aeration pipes located at the bottom may cause uneven mixing of the raw materials and gas in the upper part of the reactor when the gas density is high; conversely, aeration pipes located at the top may cause uneven mixing of the raw materials and gas in the lower part of the reactor when the gas density is low. These reactors are often used for producing a single type of electronic paste, which is quite limiting. Furthermore, different types of reactors may need to be purchased for production, leading to increased production costs.
[0005] Therefore, based on the above shortcomings, there is an urgent need to design a new type of aerated polymerization reactor to solve the problem that current reactors are mostly used to produce a single type of electronic paste, which is quite limited. Utility Model Content
[0006] The purpose of this invention is to address the limitation of current reactors, which are mostly used to produce a single type of electronic paste, by providing a new type of aerated polymerization reactor capable of producing different types of electronic pastes.
[0007] To achieve the above-mentioned objectives, this utility model provides the following technical solution:
[0008] A novel aerated polymerization reactor includes a body and a top cover. The top cover is provided with a feed inlet. An aeration pipe is provided at the center of the reactor. The aeration pipe is connected to a stirring rod, which is located inside the reactor. The aeration pipe is uniformly provided with first air holes. The aeration pipe is connected to a rotating shaft. The rotating shaft is driven to rotate by a driving device, so that the aeration pipe and the stirring rod rotate around the axis of the aeration pipe.
[0009] As the preferred technical solution of this application, the aeration pipe is provided with an outer pipe, the outer pipe is rotatable, the outer pipe is provided with a second air hole, the second air hole corresponds to the air hole of the aeration pipe, and a third air hole is also provided on one side of the outer pipe, the position of the third air hole corresponds to the position of the first air hole, the size of the third air hole gradually decreases from top to bottom, and by rotating the outer pipe, the third air hole is aligned with the first air hole, so as to change the air volume at different positions of the air hole.
[0010] As a preferred technical solution of this application, the outer tube is also provided with a fourth air hole, the position of the fourth air hole corresponds to the position of the first air hole, and the size of the fourth air hole gradually decreases from bottom to top. By rotating the outer tube, the fourth air hole is aligned with the first air hole, so as to change the air output at different positions of the air hole.
[0011] As the preferred technical solution of this application, the stirring rod is provided with several blades to enhance the stirring effect of the stirring rod.
[0012] As the preferred technical solution of this application, the blade is rotatably connected to the stirring rod, the aeration pipe is provided with a sleeve, and the blade is connected to the sleeve through a connecting rod. By moving the sleeve away from or close to the reactor body, the blade connected to the sleeve can be closed or opened.
[0013] As the preferred technical solution of this application, the aeration pipe includes a first air pipe, a second air pipe and a third air pipe. The second air pipe is located inside the reactor and is connected to the rotating shaft through the first air pipe. The third air pipe is connected to the other end of the second air pipe and is located outside the reactor. Both the first air pipe and the second air pipe are provided with pipe sleeves. The upper part of the blades of the reactor is connected to the first air pipe through a connecting rod, and the lower part of the blades is connected to the third air pipe through a connecting rod.
[0014] As the preferred technical solution of this application, the stirring rod is provided with a limit block to limit the blade when it is opened to the maximum.
[0015] As the preferred technical solution of this application, the reactor is provided with a discharge port and a discharge valve.
[0016] As the preferred technical solution of this application, the reactor is connected to a temperature sensor.
[0017] As the preferred technical solution of this application, the reactor is connected to a condenser tube.
[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0019] 1. In the present application, a novel aerated polymerization reactor is provided, wherein the aeration pipe is located at the center of the reactor itself, so that the amount of gas aerated in the upper and lower parts of the reactor is relatively uniform during aeration. After the drive device is turned on, the aeration pipe and the stirring rod are driven to rotate around the axis of rotation, which further makes the distribution of the amount of gas aerated in the reactor body more uniform. At the same time, the stirring rod stirs the raw materials, accelerates the mixing of raw materials and gas, and reduces production time.
[0020] 2. Furthermore, by setting an outer tube, when the density of the aerated gas is relatively close to the density of air, the outer tube is rotated to align the second air hole with the first air hole; when the density of the aerated gas is relatively large compared to the density of air, the outer tube is rotated to align the third air hole with the first air hole. This results in a smaller gas output from the lower part of the gas holes in the reactor and a larger gas output from the upper part of the gas holes. At the same time, the upper part of the gas sinks, achieving a more uniform distribution of the aerated gas volume in the reactor cavity.
[0021] 3. Furthermore, when the density of the aerated gas is relatively lower than that of air, the outer tube is rotated so that the fourth air hole is aligned with the first air hole. This results in a smaller gas output from the upper part of the reactor and a larger gas output from the lower part of the reactor. At the same time, the lower part of the gas rises, making the distribution of the aerated gas in the reactor cavity more uniform.
[0022] 4. Furthermore, by moving the sleeve away from or close to the reactor, the blades connected to the sleeve can be closed or opened to adjust the stirring effect of the stirring rod and blades.
[0023] 5. Furthermore, by moving the sleeves at both ends of the reactor away from or closer to the reactor body, the purpose of adjusting the opening and closing of the stirring rod blades in the upper and / or lower parts of the reactor can be achieved. When the density of the aerated gas is relatively higher than that of air, the gas in the upper part of the reactor sinks, resulting in more gas in the lower part. Adjusting the distance between the sleeve and the reactor opens the blades in the lower part of the reactor and closes the blades in the upper part of the reactor, thereby enhancing the stirring efficiency of the raw materials and gas in the lower part of the reactor. When the density of the aerated gas is relatively lower than that of air, the gas in the lower part of the reactor rises, resulting in more gas in the upper part. Adjusting the distance between the sleeve and the reactor opens the blades in the upper part of the reactor and closes the blades in the lower part of the reactor, thereby enhancing the stirring efficiency of the raw materials and gas in the upper part of the reactor.
[0024] 6. Furthermore, by setting a limit block, it is convenient to adjust the opening or closing of the blades by adjusting the distance between the sleeve and the reactor. Attached Figure Description

[0034] Therefore, the following detailed description of the embodiments of this utility model is not intended to limit the scope of the claimed utility model, but merely to illustrate some embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
[0035] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.
[0036] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0037] Example 1: This example provides a novel aerated polymerization reactor, see [link to example]. Figures 1-3 As shown,
[0038] During use, the raw materials are added into the reactor body 1 through the feed inlet 12. The aeration pipe 5 is set at the center of the reactor body, so that the amount of gas aerated in the upper and lower parts of the reactor is relatively uniform. After turning on the drive device 3 and the aeration pipe 5, the aeration pipe 5 and the stirring rod 8 are driven to rotate around the axis of the rotating shaft 4, which further makes the distribution of the amount of gas aerated in the reactor body 1 more uniform. At the same time, the stirring rod 8 stirs the raw materials, accelerates the mixing of raw materials and gas, and reduces the production time. After the production is completed, the top cover 2 is opened and the product is taken out.
[0039] As a preferred embodiment, based on the above method, further, by providing an outer tube 6, when the density of the aerated gas is relatively close to the density of air, the outer tube 6 is rotated to align the second air hole with the first air hole; when the density of the aerated gas is relatively close to the density of air, the outer tube 6 is rotated to align the third air hole with the first air hole, so that the gas output from the lower part of the gas hole in the reactor is less, while the gas output from the upper part of the gas hole is greater, and at the same time the upper part of the gas sinks, so that the gas distribution in the reactor cavity is more uniform.
[0040] As a preferred embodiment, based on the above method, further, when the density of the aerated gas is relatively small compared to the density of air, the outer tube 6 is rotated so that the fourth air hole is aligned with the first air hole, resulting in a smaller air output from the upper part of the reactor and a larger air output from the lower part of the reactor. At the same time, the lower part of the gas floats up, making the distribution of the aerated gas in the reactor cavity more uniform.
[0041] Example 2: Based on the technical solution of Example 1, further details are provided below. Figures 1-3 As shown, by moving the sleeve 7 away from or close to the reactor, the blades 10 connected to the sleeve 7 are closed or opened, thereby adjusting the stirring effect of the stirring rod 8 and the blades 10.
[0042] In a preferred embodiment, based on the above method, further, by moving the sleeves 7 at both ends of the reactor away from or close to the reactor body 1, the purpose of adjusting the opening or closing of the blades 10 of the stirring rods 8 in the upper and / or lower parts of the reactor can be achieved. When the density of the aerated gas is relatively high compared to the density of air, the gas in the upper part of the reactor sinks, resulting in more gas in the lower part. Adjusting the distance between the sleeves 7 and the reactor opens the blades 10 in the lower part of the reactor and closes the blades 10 in the upper part of the reactor, thereby enhancing the stirring efficiency of the raw materials and gas in the lower part of the reactor. When the density of the aerated gas is relatively low compared to the density of air, the gas in the lower part of the reactor rises, resulting in more gas in the upper part. Adjusting the distance between the sleeves 7 and the reactor opens the blades 10 in the upper part of the reactor and closes the blades 10 in the lower part of the reactor, thereby enhancing the stirring efficiency of the raw materials and gas in the upper part of the reactor.
[0043] As a preferred embodiment, based on the above method, a limit block 11 is further provided to facilitate the adjustment of the opening or closing of the blade 10 by adjusting the distance between the sleeve 7 and the reactor.
[0044] As a preferred embodiment, based on the above method, by providing a discharge port 13 and a discharge valve 14, after production is completed, the discharge valve 14 is opened to remove the product from the discharge port 13.
[0045] As a preferred embodiment, based on the above method, the reaction situation inside the reactor body 1 is further observed during production using a temperature sensor 15.
[0046] As a preferred embodiment, based on the above method, after production is completed, the reactor body 1 is cooled by the condenser 16.
[0047] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above.
