Description

Technical Field

[0001] The invention specifically relates to the technical field of reactors, in particular to a polymerization reaction tower reactor. Background Art

[0002] Polymerization is the process of synthesizing polymers from monomers. Low molecular weight raw materials with polymerization ability are called monomers, and polymer raw materials with larger molecular weight are called macromonomers. If monomers are polymerized to form oligomers with lower molecular weight, it is called oligomerization, and the product is called oligomer. The polymerization of one monomer is called homopolymerization, and the product is called homopolymer. The polymerization of two or more monomers is called copolymerization, and the product is called copolymer.

[0003] At present, the conventional polymerization reaction device first evacuates the interior of the kettle, and then puts the material to be polymerized into the kettle. When the material enters, the vacuum state inside the kettle is easily destroyed, allowing gas to enter. The gas in the tank inhibits the polymerization of the material, which makes the polymerization efficiency low.

[0004] When the materials are put into the kettle, the materials to be polymerized are added at one time according to a certain proportion. In this way, when the materials are heated, the materials cannot be heated at the same time, which reduces the heating efficiency and makes the polymerization reaction take a long time. The heating method used in the existing reactor is to install a ceramic heating sleeve on the outside of the reactor for heating. The above heating method requires heating the entire reactor. When the reactor is heated as a whole and the air in the reactor is heated, the internal accessories can be heated. This heating method cannot directly act on the polymer. Not only is the heating time long, the energy consumption is high, and the cost is correspondingly increased; the reaction time of the polymer is also increased, which greatly delays the polymerization efficiency of the polymer.

[0005] The present invention designs a polymerization reaction tower kettle. First, a vacuum treatment is performed on the interior of the kettle body to reduce the gas inside the kettle body. When the vacuum is drawn, the sealing baffle and the sealing movable plate in the conduit are closed to prevent the gas from entering from the discharge port. When the pressure inside the tank body reaches a predetermined value, the sealing plate on the top of the feed pipe is driven by a spring to move to the top of the discharge pipe, so that the material is transmitted to the top of the diversion layer inside the tank body, and then the material is transported through a plurality of feed pipes. When the material is transported, the vacuum treatment is continuously performed, so that when the material is transported, the heating time of the material is effectively reduced. The material enters from the bottom of the feed pipe and is transmitted to the diversion layer from the top. The material passes through the multi-layer diversion and forms a curtain in the process of diversion, which effectively improves the adhesion of the polymer. After the polymerization is completed, the vacuum treatment is first performed on the interior of the kettle body. After the gas enters, the sealing baffle and the sealing movable plate in the conduit at the bottom of the diversion layer are separated, and the polymer is transmitted to the discharge port, so that the transmission of the polymer is realized. Summary of the invention

[0006] The object of the present invention is to provide a polymerization reaction kettle. When the inside of the kettle body is in vacuum, the sealing baffle and the sealing movable plate are automatically sealed and closed. Then, multiple feeding pipes are used for the transportation of materials. In this way, the heating time during the transportation of materials is shortened. During the transportation of materials, vacuum pumping is continuously carried out. After a certain amount of materials enter, the feeding pipes are closed, and a polymerization reaction is carried out inside the kettle body. After the polymerization is completed, gas is transported into the kettle body through the negative pressure breaking pipe at the top of the tank body. At this time, the sealing baffle and the sealing movable plate are automatically opened to realize the transportation of the polymer to the discharge port and achieve the transmission of the polymer; in the present invention, through the setting of the internal structure, the fluidity of the polymer in the kettle is effectively controlled, and the polymerization of the materials is accelerated in a better fluidity, improving the reaction quality and efficiency in the kettle. Through the structure designed in the present invention, it can effectively reduce the dependence on energy, reduce the production cost of enterprises, reduce the consumption of energy required during polymerization, promote the development of the environmental protection industry by improving the production efficiency of the kettle and saving economic benefits, and promote enterprises to continuously strengthen green production and reduce the impact on the environment during production.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] In the present invention, during use, first, the inside of the tank body is evacuated through the negative pressure pipe to reduce the gas inside the tank body. During the evacuation process, when gas enters the tank body from the discharge port, the gas pushes the sealing movable plate movably installed in the conduit upward, realizing the fitting of the sealing movable plate and the sealing baffle, achieving the sealing treatment, preventing external gas from entering, and effectively realizing the evacuation treatment between the sealing movable plate and the sealing baffle;

[0017] In the present invention, while evacuating the air, when the negative pressure inside the tank reaches the preset pressure, the spring provided at the top of the feeding pipe drives the sealing plate to move upward above the discharging pipe. At this time, the feeding pipe conveys materials into the feeding pipe. During the material conveyance, the evacuation process is continuously carried out to keep the pressure inside the tank at the predetermined pressure value. This can effectively reduce the gas brought into the tank interior during the material conveyance. The material enters the first chamber of the bottom bracket of the tank through the feeding pipe.

[0018] In the present invention, when a certain polymerization amount of the material is reached, the feeding pipe is closed through the connector, and all the gas inside the tank is pumped out through the negative pressure pipe to prevent the gas from causing polymerization inhibition inside the tank. The polymer inside the tank is heated through the heater provided on one side of the feeding pipe to improve the polymerization efficiency of the material.

[0019] In the present invention, when the material is conveyed from the discharging pipe at the end of the feeding pipe to above the shunt layer, the material is transmitted through multiple shunt layers to form a curtain shape. As the material descends, the viscosity gradually increases and finally accumulates in the collection tray. Multiple conduits are provided inside the collection tray.

A partition is provided between the first chamber and the second chamber, which can prevent the unpolymerized material from entering the second chamber from the first chamber.

[0020] In the present invention, after the polymerization is completed, the internal vacuum of the tank is broken through the negative pressure breaking pipe at the top of the tank. When gas enters the tank interior, the sealing baffle and the sealing movable plate at the end of the conduit open, and the polymerized product enters the second chamber of the bracket through the conduit and is finally transmitted through the discharging port.

[0021] In the present invention, through the setting of the internal shunt layer of the kettle, the fluidity of the polymer inside the kettle is effectively controlled. In the better fluidity, the polymerization of the material is accelerated, and the reaction quality and efficiency inside the kettle are improved. Through the feeding pipe and the shunt layer designed in the present invention, the dependence on energy can be effectively reduced, the production cost of the enterprise can be reduced, the consumption of energy required during polymerization can be reduced. By improving the production efficiency of the kettle and saving economic benefits, the development of the environmental protection industry can be promoted, and enterprises can be encouraged to continuously strengthen green production and reduce the impact on the environment during production.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0042] Please refer to Figure 1-18 , in the embodiment of the present invention, a polymerization reaction tower kettle includes a polymerization reaction tower kettle body 2, and the polymerization reaction tower kettle body 2 includes a tank body 20; a feeding pipe 201 and a shunt layer 202 are arranged inside the tank body 20; a plurality of feeding pipes 201 are provided, and a sealing plate 2013 is arranged at the top of the plurality of feeding pipes 201; the sealing plate 2013 is fixedly connected to the top plate 2012 through a connecting column 2014; a spring 2015 is sleeved outside the connecting column 2014; a discharging pipe 2011 is further arranged on one side of the top of the feeding pipe 201; the discharging pipe 2011 is higher than the top of the shunt layer 202; the shunt layer 202 is arranged in a stepped shape; and multiple layers are provided; a collecting tray 2021 is arranged at the bottom of the shunt layer 202; a plurality of conduits 2022 are installed inside the collecting tray 2021; a sealing baffle 20221 is arranged at the end of the conduit 2022; a sealing movable plate 20222 is arranged on one side of the sealing baffle 20221; the sealing movable plate 20222 is cooperatively sealed with the sealing baffle 20221; the sealing movable plate 20222 is installed inside the conduit 2022; the sealing baffle 20221 is installed at the end of the conduit 2022; the end of the conduit 2022 away from the collecting tray 2021 is connected to a fixing plate 2023;

[0043] By adopting the above technical solution, during use, first, the inside of the tank body 20 is evacuated through the negative pressure pipe 4 to reduce the gas inside the tank body 20. During the evacuation process, when gas enters the tank body 20 from the discharge port 21, the gas pushes the sealing movable plate 20222 movably installed inside the conduit 2022 upward. An opening cooperating with the sealing baffle 20221 is formed at the edge position of the sealing movable plate 20222, and the angle of the opening is between 20° and 30°, so that the sealing movable plate 20222 fits with the sealing baffle 20221 to achieve sealing treatment and prevent external gas from entering. An effective evacuation process is realized between the sealing movable plate 20222 and the sealing baffle 20221.

[0044] In this embodiment, the bottom of the material conveying pipe 201 is fixedly installed in the first chamber 241 of the bottom bracket 24 of the tank body 20; the fixing plate 2023 is embedded in the second chamber 242 of the bracket 24; a partition plate 25 is arranged between the first chamber 241 and the second chamber 242.

[0045] Specifically, the bottom of the first chamber 241 is connected to the feed pipe 23; the bottom of the second chamber 242 is provided with a discharge port 21; one end of the feed pipe 23 away from the tank body 20 is hermetically connected to the feeding assembly 1 through a connector 3; the feeding assembly 1 includes two storage tanks 10; the storage tanks 10 are fixedly installed on the frame body 11 and the output end is hermetically connected to the connector 3.

[0046] By adopting the above technical solution, while evacuating, when the negative pressure inside the tank body 20 reaches the preset pressure, the spring 2015 arranged at the top of the material conveying pipe 201 drives the sealing plate 2013 to move upward above the discharge pipe 2011. At this time, the feed pipe 23 conveys materials into the material conveying pipe 201. During the material conveying process, the evacuation process continues. In this way, the gas brought into the tank body 20 during the material conveying process can be effectively reduced. The materials enter the first chamber 241 of the bottom bracket 24 of the tank body 20 through the feed pipe 23. A plurality of material conveying pipes 201 are fixedly installed in the first chamber 241. The materials enter from the bottom of the material conveying pipe 201 and are transmitted to above the diversion layer 202 through the discharge pipe 2011. During the material transmission process, the materials inside the material conveying pipe (201) are effectively heated by the heater (5) arranged on one side of the material conveying pipe (201). Through the heating treatment of the materials during the transmission process, by arranging a plurality of material conveying pipes 201, the time required for heating the materials can be effectively reduced and the heating efficiency can be improved. By arranging a plurality of material conveying pipes 201; in this way, during heating, compared with the traditional heating method, the heating speed can be increased while the heating efficiency can also be improved;

[0047] In this embodiment, a negative pressure pipe 4 is provided on one side of the tank body 20; the negative pressure pipe 4 and the discharge port 21 are on the same side; a heater 5 is provided on the opposite surface of the negative pressure pipe 4; the heater 5 is provided on one side of the material conveying pipe 201;

[0048] A negative pressure breaking pipe 22 is provided at the top of the tank body 20; and a plurality of legs are provided at the bottom.

[0049] By adopting the above technical solution, when the material reaches a certain polymerization amount, the feed pipe 23 is closed through the connector 3, and all the gas inside the tank body 20 is pumped out through the negative pressure pipe 4 to prevent the gas from causing polymerization inhibition inside the tank body 20, and then the negative pressure pipe 4 is closed.

[0050] In this embodiment, the sealing plate 2013 is located below the discharge pipe 2011 under normal pressure.

[0051] By adopting the above technical solution, when the material is conveyed from the discharge pipe 2011 at the end of the material conveying pipe 201 to above the diversion layer 202, the material is transmitted through the plurality of diversion layers 202 to form a curtain shape. As the polymer descends, after passing through multiple diversion layers 202, during the descending process, the viscosity gradually increases and finally accumulates in the collection tray 2021. A plurality of conduits 2022 are provided inside the collection tray 2021. The bottom of the conduit 2022 is fixedly installed on the fixing plate 2023. The fixing plate 2023 is embedded in the second chamber 242 of the bracket 24, and the conduit 2022 passes through the fixing plate 2023 and extends into the second chamber 242; a partition plate 25 is provided between the first chamber 241 and the second chamber 242, which can prevent the unpolymerized material from entering the second chamber 242 from the first chamber 241.

[0052] In this embodiment, the diversion layer 202 and the collection tray 2021 are separately arranged; and the conduit 2022 provided inside the collection tray 2021 passes through the fixing plate 2023 and extends into the second chamber 242.

[0053] By adopting the above technical solution, after the polymerization is completed, the inside of the tank body 20 is broken to vacuum through the negative pressure breaking pipe 22 at the top of the tank body 20. When gas enters the inside of the tank body 20, the sealing baffle 20221 and the sealing movable plate 20222 at the end of the conduit 2022 are opened, and one end of the sealing movable plate 20222 inclines downward. The polymerized product enters the second chamber 242 of the bracket 24 through the conduit 2022, and finally the polymer is transmitted through the discharge port 21.

[0054] The working principle of the present invention is as follows: When in use, first, the inside of the tank body 20 is evacuated through the negative pressure pipe 4 to reduce the gas inside the tank body 20. During the evacuation process, when gas enters the tank body 20 from the discharge port 21, the gas pushes the sealing movable plate 20222 movably installed inside the conduit 2022 upward, causing the sealing movable plate 20222 to fit against the sealing baffle 20221, achieving a sealing effect and preventing external gas from entering. An effective evacuation process is realized between the sealing movable plate 20222 and the sealing baffle 20221;

[0055] At the same time as the evacuation, when the negative pressure inside the tank body 20 reaches the preset pressure, the spring 2015 provided at the top of the feed pipe 201 drives the sealing plate 2013 to move upward above the discharge pipe 2011, enabling the first chamber 241 of the bracket 24 to communicate with the inside of the tank body 20. The feed pipe 23 conveys materials into the feed pipe 201. During the material conveyance, the evacuation process continues. This can effectively reduce the gas brought into the tank body 20 during the material conveyance process. The materials enter the first chamber 241 of the bracket 24 at the bottom of the tank body 20 through the feed pipe 23. Multiple feed pipes 201 are fixedly installed in the first chamber 241. The materials enter from the bottom of the feed pipe 201 and are conveyed to above the shunt layer 202 through the discharge pipe 2011. During the upward conveyance process, the materials are heated by the heater 5 provided on one side of the feed pipe 201. By providing multiple feed pipes 201, the time required for heating the materials can be effectively reduced, improving the heating efficiency;

[0056] When a certain polymerization amount of materials is reached, the feed pipe 23 is closed through the connector 3, and all the gas inside the tank body 20 is pumped out through the negative pressure pipe 4 to prevent the gas from causing polymerization inhibition inside the tank body 20;

[0057] When the materials are conveyed from the discharge pipe 201 at the end of the feed pipe 201 to above the shunt layer 202, the materials are transmitted through multiple shunt layers 202 to form a curtain shape. As the materials fall, the viscosity gradually increases and finally accumulates in the collection tray 2021. A plurality of conduits 2022 are provided inside the collection tray 2021. The bottom of the conduit 2022 is fixedly installed on the fixing plate 2023. The fixing plate 2023 is embedded in the second chamber 242 of the bracket 24, and the conduit 2022 penetrates through the fixing plate 2023 and extends into the second chamber 242. A partition plate 25 is provided between the first chamber 241 and the second chamber 242, which can prevent the unpolymerized materials from entering the second chamber 242 from the first chamber 241;

[0058] After polymerization is completed, internal vacuum breaking treatment is carried out through the negative pressure breaking pipe 22 at the top of the tank body 20. When gas enters the tank body 20, the sealing baffle 20221 and the sealing movable plate 20222 at the end of the conduit 2022 open, and the polymerized product enters the second chamber 242 of the bracket 24 through the conduit 2022, and finally the polymer is transported through the discharge port 21.

[0059] Through the setting of the internal shunt layer 202 in the kettle, the fluidity of the polymer in the kettle is effectively controlled. In a better fluidity, the polymerization of the material is accelerated, and the reaction quality and efficiency in the kettle are improved. Through the designed feeding pipe 201 and the shunt layer 202 of the present invention, it is possible to effectively reduce the dependence on energy, reduce the production cost of the enterprise, reduce the consumption of energy required during polymerization, promote the development of the environmental protection industry by improving the production efficiency of the kettle and saving economic benefits, and encourage enterprises to continuously strengthen green production and reduce the impact on the environment during production.
