Description

Technical Field

[0001] This utility model relates to the field of reaction vessel technology, specifically an environmentally friendly chemical reaction vessel. Background Technology

[0002] In a broad sense, a reaction vessel is a container where physical or chemical reactions occur. Through structural design and parameter configuration, it achieves the heating, evaporation, cooling, and low-to-high-speed mixing functions required by the process. Reaction vessels are widely used in petroleum, chemical, rubber, pesticide, dye, pharmaceutical, and food industries as pressure vessels to complete processes such as vulcanization, nitration, hydrogenation, hydrocarbonation, polymerization, and condensation.

[0003] Currently, the production processes of high-end display optoelectronic materials and fine chemicals involve various chemical reactions. These reactions often require specific conditions, such as precise temperature control, high mixing efficiency, and low environmental impact. Environmentally friendly chemical reactors play a crucial role in such production processes.

[0004] Current chemical reaction vessels on the market have some shortcomings in design and function. Specifically, existing reaction vessels generally use a single stirring rod, which has a relatively simple stirring function. This often results in the materials inside the vessel not being fully and uniformly stirred. This lack of stirring and mixing efficiency directly affects the uniformity and overall efficiency of the chemical reaction.

[0005] In addition, material tends to accumulate on the inner wall of the reactor during the stirring process. Although some designs use a stirring rod to drive a scraper to scrape off the material from the side wall, thus reducing material adhesion, this design will wear down faster due to the continuous contact between the scraper and the reactor wall over a long period of time. Therefore, we propose an environmentally friendly chemical reactor to solve the above-mentioned problems. Utility Model Content

[0006] In view of the shortcomings of the existing technology, this utility model provides an environmentally friendly chemical reaction vessel, which solves the problems of insufficient stirring and mixing efficiency and accelerated wear due to continuous contact between the scraper and the vessel wall during long-term operation.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: an environmentally friendly chemical reaction vessel, including a support frame, wherein a lower vessel body for accommodating reactants is mounted on the support frame;

[0011] The bottom of the first stirring rod is provided with a U-shaped plate;

[0012] The U-shaped plate is equipped with several sets of scraping sections for scraping off materials adhering to the side wall of the lower vessel.

[0013] When the first stirring rod and the U-shaped plate rotate clockwise under the drive of the driving unit, the scraper of the scraping unit contacts the side wall of the lower vessel body, while when it rotates counterclockwise, the scraper separates from the side wall of the lower vessel body.

[0014] Preferably, there are two sets of the second stirring rods, which are symmetrically arranged and distributed on both sides of the first stirring rod.

[0015] Preferably, one set of the second stirring rods has equidistantly arranged dispersing discs fixedly mounted on its surface, with the topmost dispersing disc corresponding to the feeding port of the top cover.

[0016] Preferably, the drive unit includes a support frame fixedly installed at the center of the top of the top cover and a positive and negative motor fixedly installed on the support frame by bolts;

[0017] A connecting seat is fixedly installed on the inner side wall of the top cover. A circular through hole is opened at the center of the connecting seat. The top end of the first stirring rod passes through the circular through hole and is fixedly connected to the output end of the positive and negative motors through a coupling. The top end of the second stirring rod is rotatably installed through a bearing and the connecting seat. A first gear is fixedly installed on the top of the first stirring rod near the connecting seat.

[0020] Preferably, the scraper is arranged with an inclined structure, one end of each of the two sets of first push rods is attached to one side of the scraper, and the second push rod has an movable gap with the corresponding side of the scraper.

[0021] Preferably, the surfaces of the stirring blades of the first and second stirring rods are provided with multiple sets of through holes. Beneficial effects

[0022] This invention provides an environmentally friendly chemical reaction vessel. Compared with the prior art, it has the following advantages:

[0023] This environmentally friendly chemical reactor employs a multi-stirring rod structure. The first stirring rod, the second stirring rod, and the U-shaped plate work together to achieve multi-directional stirring of the materials inside the reactor, ensuring that the materials are fully and uniformly stirred. This significantly improves the uniformity and overall efficiency of the chemical reaction. Simultaneously, the use of a scraper effectively removes materials adhering to the side wall of the lower reactor body, ensuring thorough mixing and enhancing the stirring effect. Furthermore, the device allows for flexible control of whether the scraper of the scraper contacts the side wall of the lower reactor body according to actual usage needs. This eliminates the need for the scraper to be constantly in contact with the side wall, reducing friction and wear between the scraper and the lower reactor body, thus extending the scraper's service life and improving the overall performance of the device.

Detailed Implementation

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] like Figure 1-5 As shown:

[0032] An environmentally friendly chemical reactor includes a support 101, on which a lower reactor body 102 for containing reactants is mounted.

[0033] The top opening of the lower vessel 102 is provided with a top cover 103. The top cover 103 is connected to the corresponding flange on the top of the lower vessel 102 through a flange and is fastened with bolts to form a sealed cavity. At the same time, an O-ring is provided between the top cover 103 and the lower vessel 102 for compression and sealing connection, so as to reduce leakage during the chemical reaction process and achieve environmental protection effect.

[0034] The lower vessel body 102 is provided with a first stirring rod 104 and multiple sets of second stirring rods 105, wherein there are two sets of second stirring rods 105, which are symmetrically arranged and distributed on both sides of the first stirring rod 104.

[0035] A drive unit 2 is installed on the top cover 103 to drive the first stirring rod 104 and the second stirring rod 105 to rotate, and the first stirring rod 104 and the second stirring rod 105 stir in opposite directions.

[0036] The drive unit 2 includes a support frame 201 fixedly installed at the center of the top of the top cover 103 and a forward and reverse motor 202 fixedly installed on the support frame 201 by bolts;

[0037] A connecting seat 203 is fixedly installed on the inner side wall of the top cover 103. A circular through hole is opened at the center of the connecting seat 203. The top end of the first stirring rod 104 passes through the circular through hole and is fixedly connected to the output end of the forward and reverse motor 202 through a coupling. The top end of the second stirring rod 105 is rotatably installed through a bearing and the connecting seat 203. A first gear 204 is fixedly installed on the top of the first stirring rod 104 near the connecting seat 203. A second gear 205 that meshes with the first gear 204 is fixedly installed on the top of the second stirring rod 105. The top part of the first stirring rod 104 is installed in the circular through hole of the connecting seat 203 through a bearing. The first stirring rod 104 is rotatably connected to the top cover 103 through a sealed bearing.

[0038] The bottom of the first stirring rod 104 is provided with a U-shaped plate 106;

[0039] Several sets of scraping parts 3 are installed on the U-shaped plate 106 for scraping off the material adhering to the side wall of the lower vessel body 102. The scraping part 3 includes symmetrical fixing blocks 301 fixedly installed on the surface of the U-shaped plate 106 by bolts. A fixing shaft 302 is fixedly installed between the two sets of fixing blocks 301. A scraper 303 is rotatably installed on the fixing shaft 302 through a sealed bearing. A first push rod 304 is fixedly installed on one side of the surface of the U-shaped plate 106 near the scraper 303, and a second push rod 305 is fixedly installed on the other side, arranged symmetrically.

[0040] The scraper 303 is set with an inclined structure. One end of the two sets of first push rods 304 is attached to one side of the scraper 303, and the second push rod 305 has an movable gap with the corresponding side of the scraper 303.

[0041] When the first stirring rod 104 and the U-shaped plate 106 rotate clockwise under the drive of the drive unit 2, the scraper 303 of the scraper unit 3 contacts the side wall of the lower vessel 102, while when it rotates counterclockwise, the scraper 303 separates from the side wall of the lower vessel 102.

[0042] In this implementation scheme: When using the environmentally friendly chemical reactor, materials, solvents, and reaction media are fed into the cavity of the lower reactor body 102 through the feeding port of the top cover 103. When it is necessary to stir the materials, the first stirring rod 104 and the second stirring rod 105 are driven to rotate by the drive unit 2. Specifically, the forward and reverse motor 202 on the support frame 201 is connected to an external power source and energized. The forward and reverse motor 202 is started, and it drives the first stirring rod 104 to rotate through the coupling. As the first stirring rod 104 rotates, it further drives the first gear 204 to rotate. A gear 204 meshes with two sets of second gears 205, thereby driving the two sets of second gears 205 to rotate synchronously. The rotation of the second gears 205 in turn drives the two sets of second stirring rods 105 to rotate. In this way, the second stirring rods 105 and the first stirring rod 104 can rotate simultaneously, and the first stirring rod 104 and the second stirring rod 105 rotate in opposite directions. This opposite direction stirring can enhance the flow of fluid in the lower vessel 102, generate reverse shear force, help break up the clumps in the material, promote the interaction between materials, thereby achieving more uniform material mixing and improving reaction efficiency.

[0043] As the first stirring rod 104 rotates, it will drive the U-shaped plate 106 to rotate. Through the rotation of the U-shaped plate 106, the scraper 3 will rotate synchronously. In this way, the scraper 3 can scrape off the material attached to the side wall of the lower vessel 102, so as to achieve full mixing of the material.

[0044] The U-shaped plate 106 consists of an arc-shaped plate and two sets of vertical plates. Each set of vertical plates is equipped with a scraper 3. The scraper 3 on the two sets of vertical plates is staggered. The length of the vertical plate of the U-shaped plate 106 is matched with the overall length of the staggered scraper 3. This staggered installation not only saves manufacturing costs, but also allows the scraper 3 to be installed on half of the arc-shaped part of the U-shaped plate 106 so as to scrape the bottom wall of the lower vessel 102.

[0045] While the drive unit 2 drives the first stirring rod 104 to rotate, it also drives the U-shaped plate 106 to rotate. The U-shaped plate 106 then drives the fixed block 301, scraper 303 and other components to rotate clockwise. As the scraper 303 rotates, due to the resistance of the liquid, one side of the scraper 303 will abut against one end of the first push rod 304. At this time, the scraper 303 adopts an inclined structure design, and one end of it abuts against the side wall of the lower vessel 102. As the U-shaped plate 106 drives the scraper 303 to rotate, the material on the side wall of the lower vessel 102 is scraped off.

[0046] like Figure 5 As shown: When the forward and reverse motor 202 drives the first stirring rod 104 and the U-shaped plate 106 to rotate counterclockwise, due to the resistance of the liquid, the scraper 303 will rotate around the fixed shaft 302. An movable gap is provided between the scraper 303 and the second push rod 305, so that the scraper 303 can be folded towards the second push rod 305. At this time, one side of the scraper 303 abuts against one end of the second push rod 305, so that the scraper 303 can be separated from the side wall of the lower vessel 102. By driving the forward and reverse rotation of the first stirring rod 104 and the U-shaped plate 106 and other components driven by the forward and reverse motor 202, it is possible to control whether the scraper 303 contacts the side wall of the lower vessel 102. When scraping is not required, the forward and reverse motor 202 on the drive unit 2 can rotate in the opposite direction. At this time, the scraper 303 will not contact the side wall of the lower vessel 102, thereby reducing wear.

[0047] This design employs a multi-stirring rod structure, with the first stirring rod 104, the second stirring rod 105, and the U-shaped plate 106 working in tandem to achieve multi-directional stirring of the materials inside the vessel. This ensures that the materials are thoroughly and uniformly stirred, thereby significantly improving the uniformity and overall efficiency of the chemical reaction. Simultaneously, in conjunction with the scraper section 3, it effectively scrapes away materials adhering to the side wall of the lower vessel 102, ensuring thorough mixing and enhancing the stirring effect. Furthermore, the device can flexibly control whether the scraper 303 of the scraper section 3 contacts the side wall of the lower vessel 102 according to actual usage requirements. The scraper 303 does not need to be in constant contact with the side wall, thus reducing friction between the scraper 303 and the lower vessel 102, reducing wear, extending the service life of the scraper 303, and improving the overall performance of the device.

[0048] It should be noted that all electrical equipment involved in this product is powered by an external power source, and the power connection method of each electrical device is a mature existing technology, which is well known to those in the field, and will not be elaborated further here.

[0049] It should be noted that the lower vessel body 102 and the top cover 103 are not described in detail in this specification. They are implemented using existing technologies known to those skilled in the art. The connection of the lower vessel body 102 and the top cover 103 to other equipment, as well as heating and cooling, will not be described in detail. For details, please refer to the patent document CN208018597U.

[0050] Furthermore;

[0051] In an optional embodiment, a set of second stirring rods 105 are fixedly mounted with equidistantly arranged dispersing discs 107, with the topmost dispersing disc 107 corresponding to the feeding port of the top cover 103.

[0052] In this embodiment: the second stirring rod 105 is provided with multiple dispersing discs 107. The outer surface of the dispersing discs 107 is designed with a serrated shape to enhance shear force and help disperse clumps in the material. At the same time, this design increases the contact area of ​​the material. Through the rotation of the dispersing discs 107, the material is effectively dispersed, improving the dispersion efficiency. This helps the material flow uniformly in the lower vessel 102, enhances the fluidity of the material, and further improves the stirring effect.

[0053] The topmost dispersing disc 107 corresponds to the feeding port of the top cover 103. When liquid material is fed, the solution falls onto the upper surface of the dispersing disc 107. As the dispersing disc 107 rotates, the liquid can be effectively dispersed, reducing the need for concentrated feeding.

[0054] Furthermore;

[0055] In an optional embodiment, a housing cover 206 is fixedly installed on the inner side wall of the top cover 103 to shield the first gear 204 and the second gear 205. The first stirring rod 104 and the second stirring rod 105 are rotatably connected to the housing cover 206 through a sealed bearing.

[0056] In this embodiment, the housing cover 206 and the top cover 103 can form a sealed protective cavity, which can shield and protect components such as the first gear 204 and the second gear 205, and prevent the debris from falling off due to long-term meshing and wear of the first gear 204 and the second gear 205 from contaminating the reactants.

[0057] The housing cover 206 and the top cover 103 can be fixed by welding. The housing cover 206 and the top cover 103 can form a sealed protective cavity, so as not to affect the injection of lubricating oil into the first gear 204 and the second gear 205, thereby improving the performance of this structure.

[0058] It should be noted that the housing cover 206 has an opening, and a sealing plate is provided at the opening. A sealing gasket (made of silicone) is installed on one side of the sealing plate to increase the sealing between the sealing plate and the housing cover 206. At the same time, the sealing plate is locked to the housing cover 206 by screws. By opening the sealing plate, it is convenient to maintain the first gear 204 and the second gear 205 and increase the lubrication operation.

[0059] In an optional embodiment, the stirring blades of the first stirring rod 104 and the second stirring rod 105 have multiple sets of through holes.

[0060] In this embodiment, the stirring blades of the first stirring rod 104 and the second stirring rod 105 have multiple sets of through holes. During the rotation of the stirring rod, some liquid can flow through these through holes, reducing the direct impact of the fluid on the stirring blades, reducing shear force, thereby reducing resistance and improving the rotation effect of the first stirring rod 104 and the second stirring rod 105.

[0061] The working principle and usage process of this utility model are as follows: When using this environmentally friendly chemical reactor, materials, solvents, and reaction media are fed into the lower reactor body 102 cavity through the feeding port of the top cover 103. The forward and reverse motors 202 drive the first stirring rod 104 to rotate via a coupling. The first stirring rod 104 drives the first gear 204 to rotate, which in turn drives the second stirring rod 105 to rotate via the meshing second gear 205. The two stirring rods rotate in opposite directions, enhancing fluid flow and shear force, achieving uniform mixing of materials. Simultaneously, the first stirring rod 104 drives the U-shaped plate 106 to rotate, causing the scraper 3 to scrape off the material adhering to the side wall of the lower reactor body 102, promoting thorough mixing. When the forward and reverse motors 202 drive the first stirring rod 104 and the U-shaped plate 106 to rotate counterclockwise, due to the resistance of the liquid, the scraper 303 will rotate at an angle around the fixed shaft 302. An adjustable gap is provided between the scraper 303 and the second top rod 305, allowing the scraper 303 to... The scraper 303 can be folded towards the second push rod 305. At this time, one side of the scraper 303 abuts against one end of the second push rod 305, so that the scraper 303 can be separated from the side wall of the lower vessel 102. By driving the first stirring rod 104 and U-shaped plate 106 and other components to rotate in the forward and reverse directions through the forward and reverse motor 202, it is possible to control whether the scraper 303 contacts the side wall of the lower vessel 102. When scraping is not required, the forward and reverse motor 202 on the drive unit 2 can rotate in the reverse direction. At this time, the scraper 303 will not contact the side wall of the lower vessel 102, thereby reducing wear.

[0062] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
