Description

Technical Field

[0001] The utility model relates to the technical field of low-halogen bio-based epoxy diluent processing, and specifically relates to a solvent stripping device for low-halogen bio-based epoxy diluents. Background Technique

[0002] Low-halogen bio-based epoxy diluents are a new type of environmentally friendly diluents that combine the two characteristics of low halogen and bio-based, aiming to provide a more environmentally friendly option. Such diluents have the following remarkable characteristics:

[0003] Low halogen: This means that the halogen content in the diluent is low, which helps to reduce the negative impact on the environment. Halogen is a common flame retardant element, but in some applications, too high halogen content may have a negative impact on the environment. Therefore, the development of low-halogen diluents is of great significance.

[0004] Bio-based: Bio-based materials are derived from renewable resources such as plants and crops. Using such materials can reduce the dependence on fossil fuels and also help to reduce greenhouse gas emissions. The use of bio-based diluents helps to promote sustainable development and circular economy.

[0005] Environmental protection performance: In addition to the low-halogen and bio-based characteristics, such diluents usually also have good environmental protection performance, including low toxicity, low volatile organic compound emissions, etc., which helps to protect the environment and human health.

[0006] Application fields: Low-halogen bio-based epoxy diluents are applicable to a variety of application scenarios, including but not limited to coatings, adhesives, electronic packaging materials, etc., and their application in epoxy resin systems is particularly extensive;

[0007] Among them, a special solvent stripping device will be used in the production process of such diluents. The solvent stripping device is a kind of equipment, mainly used to promote the phenomenon that solute atoms segregate and precipitate to form a new phase in a supersaturated solid solution; this process can be subdivided into equilibrium precipitation and aging precipitation, as well as continuous precipitation and discontinuous precipitation, depending on the regional distribution of precipitation and the precipitation process; the design and application of the solvent stripping device are aimed at promoting this chemical process to occur, so as to achieve specific chemical or physical changes in industrial production.

[0008] Conventional solvent stripping devices are a kind of equipment containing a kettle, with a discharge port at the bottom and a mixing and processing device with a stirring shaft and stirring blades inside. However, due to the relatively fixed structure and relying only on the operation of the internal stirring blades, the processing effect is relatively limited and the efficiency is lacking.

[0009] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and a solvent stripping device for low-halogen bio-based epoxy diluents is proposed. Summary of the Utility Model

Moreover, a stabilizing beam is horizontally installed on the top of the sliding piles, and buffer piles are arranged on the surface of the stabilizing beam. At the same time, a limit plate is connected to the side of the buffer pile close to the solvent stripping kettle.

[0012] Further, the solvent stripping kettle includes a processing kettle, an upper cover, and a feed valve. The upper cover is installed on the upper part of the processing kettle, and a feed valve is installed on the upper side edge of the processing kettle.

[0013] Further, the solvent stripping kettle further includes a lower cover and a discharge valve. The lower cover is installed at the bottom of the processing kettle, and a discharge valve is installed at the center of the bottom of the lower cover.

[0014] Further, both the upper cover and the lower cover are connected to the processing kettle by flange structures, and six groups of feed valves are installed in a circular array with the processing kettle as the center.

[0015] Further, the stirring assembly includes a stirring shaft, connecting rods, stirring blades, and scraping plates. Connecting rods are horizontally installed on the surface of the stirring shaft, and stirring blades are vertically connected to the ends of the connecting rods far from the stirring shaft. Moreover, scraping plates are installed on the sides of the stirring blades far from the connecting rods.

[0016] Further, four groups of connecting rods are installed in a circular array with the stirring shaft as the center, and three rows of connecting rods are vertically arranged at equal intervals from top to bottom.

[0019] The present utility model provides a solvent stripping device for low-halogen bio-based epoxy diluents, having the following

[0020] Advantages:

[0021] 1. In this utility model, since electric swing frames are installed on both sides of the desolventization kettle, by utilizing the operation of the electric swing frame structure, the desolventization kettle can swing left and right within a certain angle range in the vertical direction, thereby assisting the stirring component inside the desolventization kettle to stir and mix the materials, ensuring the mixing efficiency and sufficiency. At the same time, on both sides of the desolventization kettle, through the operation of the sliding pile structure, the buffer pile and the limit plate connected to the top of the stabilizing beam can move left and right along the surface of the guide rail, thereby adjusting the relative distance between the buffer pile, the limit plate and the desolventization kettle. By using the above structure, through the elastic telescoping of the buffer pile structure and the blocking and buffering of the limit plate, it is possible to minimize the situation where when the desolventization kettle swings and adjusts driven by the electric swing frame, once the electric swing frame fails and causes a fall, resulting in structural collision or uncontrolled reciprocating swing, playing the role of structural limit and structural buffer protection. At the same time, the flexibility of its structure also avoids causing structural interference to the swinging and adjusting desolventization kettle, ensuring both the flexibility of the structure and providing the stability of the structure.

[0022] 2. In this utility model, six feeding valves are annularly and arrayedly installed on the upper surface of the processing kettle, so that various different materials can be injected into the interior of the processing kettle simultaneously according to needs, ensuring both the convenience of structural use and the efficiency of processing operations. After the servo motor on the top of the upper cover operates, the stirring shaft connected to it will rotate axially inside the desolventization kettle, causing the stirring blades connected to it by connecting rods to rotate synchronously inside the processing kettle. At the same time, the scraping plate connected to the stirring blade will move along the surface of the processing kettle, thereby assisting the stirring blade in mixing the materials and reducing the problem of material adhesion to a certain extent. In addition, the stirring shaft, the connecting rod, and the stirring blade are connected to each other by a threaded structure, making the structure have flexible disassembly and assembly for easy structural maintenance.

A stirring assembly 2 is installed inside the precipitation kettle 1, and a servo motor 3 is installed on the top of the precipitation kettle 1. Electric swing frames 4 are installed on both sides of the servo motor 3. The buffer frame 5 is arranged on the left and right sides of the electric swing frame 4. The buffer frame 5 includes a fixed pile 501, a guide rail 502, a sliding pile 503, a stabilizing beam 504, a buffer pile 505, and a limiting plate 506. Guide rails 502 are horizontally installed on the left and right sides of the fixed pile 501, and a sliding pile 503 is slidably installed on the surface of the guide rail 502. A stabilizing beam 504 is horizontally installed on the top of the sliding pile 503, and buffer piles 505 are arranged on the surface of the stabilizing beam 504. At the same time, a limiting plate 506 is connected to the side of the buffer pile 505 close to the precipitation kettle 1. By using the structural operation of the electric swing frame 4, the precipitation kettle 1 can swing left and right within a certain angle range in the vertical direction, so as to assist the stirring assembly 2 inside the precipitation kettle 1 to mix the materials. Through the structural operation of the sliding pile 503, the buffer piles 505 and the limiting plate 506 connected to the top of the stabilizing beam 504 can move left and right along the surface of the guide rail 502, so as to change the relative distance between the buffer pile 505, the limiting plate 506 and the precipitation kettle 1.

[0029] As Figures 1 to 3As shown in the figure, the stripping kettle 1 includes a processing kettle 101, an upper cover 102 and a feed valve 103. The upper cover 102 is installed on the upper part of the processing kettle 101, and the feed valve 103 is installed on the side of the upper end of the processing kettle 101. The stripping kettle 1 further includes a lower cover 104 and a discharge valve 105. The lower cover 104 is installed at the bottom of the processing kettle 101, and the discharge valve 105 is installed at the center of the bottom of the lower cover 104. Both the upper cover 102 and the lower cover 104 are connected to the processing kettle 101 by flange structures, and six groups of feed valves 103 are installed in a circular array with the processing kettle 101 as the center. The stirring assembly 2 The stirring assembly 2 includes a stirring shaft 201, a connecting rod 202, a stirring blade 203 and a scraper 204. The connecting rod 202 is horizontally installed on the surface of the stirring shaft 201, and the stirring blade 203 is vertically connected to the end of the connecting rod 202 away from the stirring shaft 201. Moreover, a scraper 204 is installed on the side of the stirring blade 203 away from the connecting rod 202. Four groups of connecting rods 202 are installed in a circular array with the stirring shaft 201 as the center, and three rows of connecting rods 202 are arranged vertically and equidistantly from top to bottom. The stirring shaft 201, the connecting rod 202 and the stirring blade 203 are connected to each other by a threaded structure, and the stirring blade 203 and the scraper 204 are fixedly connected. The top of the stirring shaft 201 is connected to the power output end of the servo motor 3 through a coupling, and the servo motor 3 is fixed on the top surface of the upper cover 102. When the servo motor 3 on the top of the upper cover 102 operates, the connected stirring shaft 201 will rotate axially inside the stripping kettle 1, so that the stirring blade 203 connected by the connecting rod 202 will rotate synchronously inside the processing kettle 101. At the same time, the scraper 204 connected to the stirring blade 203 will move along the surface of the processing kettle 101, so as to assist the stirring blade 203 in mixing the materials and reduce the problem of material adhesion to a certain extent.

[0030] In summary, as Figures 1 to 3 shown, when using the stripping device for the low-halogen bio-based epoxy diluent, first, different materials are simultaneously injected through the six groups of feed valves 103 distributed on the upper surface of the processing kettle 101, and then the servo motor 3 installed on the top of the upper cover 102 is started. Driven by the servo motor 3, the entire stirring assembly 2 connected by the stirring shaft 201 will rotate vertically axially inside the processing kettle 101. During this process, the stirring blade 203 and the scraper 204 are connected to the rotating stirring shaft 201 through the connecting rod 202, so as to operate synchronously and mix and stir the materials inside the processing kettle 101.

[0031] During this process, with the operation of the electric swing frame 4, the entire stripping kettle 1 will swing and adjust at a certain angle left and right in the vertical direction to maintain different inclination angles to assist the stirring assembly 2 in mixing the materials.

[0032] Meanwhile, the buffer rack 5 will also operate synchronously. Under the operation of the sliding pile 503, the buffer pile 505 and the limit plate 506 connected thereto by the stabilizing beam 504 will translate along the surface of the guide rail 502 on both sides of the fixed pile 501, providing structural protection without causing structural interference thereto. After the processing is completed, the material is taken out through the discharge valve 105 at the bottom of the lower cover 104 for subsequent processing.
