Technical Field

[0001] This utility model relates to the field of plastic reactors, specifically an engineering plastic reactor. Background Technology

[0002] A reactor is a device used to realize a reaction process and is widely used in chemical, oil refining, and metallurgical industries. Reactors are used to realize single-phase liquid reaction processes and multiphase reaction processes such as liquid-liquid, gas-liquid, liquid-solid, and gas-liquid-solid reactions.

[0018] like Figures 1 to 5As shown, an engineering plastic reactor includes a reaction tank 1; a feed pipe 12 is connected to the top of the reaction tank 1, a feed inlet is connected to the side of the feed pipe 12, a discharge valve 13 is connected to the bottom of the reaction tank 1, a heating tank 14 is provided inside the reaction tank 1, an air inlet is connected to the heating tank 14, a first motor 15 is fixedly connected to the side of the reaction tank 1, a first screw 16 is fixedly connected to the output end of the first motor 15, a first moving plate 17 is threadedly connected to the surface of the first screw 16, a first sealing plate 18 is fixedly connected to the side of the first moving plate 17, and the side of the first sealing plate 18 is connected to the top of the feed pipe 12. The bottom of the first sealing plate 18 is fixedly connected to a first heat insulation block 19, which is slidably connected to the feed pipe 12. A second motor 110 is fixedly connected to the bottom of the reaction vessel 1. A second screw 111 is fixedly connected to the output end of the second motor 110. A second moving plate 112 is threaded onto the surface of the second screw 111. A sealing ring 113 is fixedly connected to the inner side of the second moving plate 112, and the inner side of the sealing ring 113 is in contact with the discharge valve 13. During operation, the first motor 15 drives the first screw 16 to rotate, which in turn drives the first moving plate 17 to move. Plate 17 drives the first sealing plate 18 to move, which in turn drives the first heat insulation block 19 to move, separating it from the feed pipe 12. At this time, the raw material can be poured into the interior of the reaction tank 1 through the feed port on the side of the feed pipe 12, and heating gas is pushed into the interior of the heating tank 14 to heat the raw material inside the reaction tank 1. The first motor 15 drives the first screw 16 to reverse, which in turn drives the first moving plate 17 to move downward, which in turn drives the first sealing plate 18 to move, causing the first heat insulation block 19 to be inserted into the interior of the feed pipe 12. When it is necessary to discharge the raw material, the second motor... The machine 110 drives the second screw 111 to rotate, which in turn drives the second moving plate 112 to move to both sides, separating the second moving plate 112 from the discharge valve 13. Then the discharge valve 13 can be opened to discharge the raw materials inside the reaction tank 1. In this step, the first sealing plate 18 and the first heat insulation block 19, which can move up and down, can seal and insulate the feed pipe 12. The sealing ring 113, which can move left and right, can seal and insulate the discharge valve 13, reducing the outflow of heat from inside the reaction tank 1 and achieving the effect of heat preservation for the reaction tank 1, thereby increasing the heating efficiency inside the reaction tank 1.

[0019] like Figure 3As shown, a third motor 21 is fixedly connected to the top of the reaction vessel 1. A stirring rod 22 is fixedly connected to the output end of the third motor 21. A first scraper 23 is fixedly connected to the side of the stirring rod 22. The surface of the first scraper 23 is in contact with the inner wall of the reaction vessel 1. During operation, when the raw material is poured into the reaction vessel 1, the third motor 21 drives the stirring rod 22 to rotate, which in turn drives the first scraper 23 to rotate. The stirring rod 22 and the first scraper 23 stir the raw material inside the reaction vessel 1. This step increases the efficiency of the reaction and heating of the raw material inside the reaction vessel 1. The first scraper 23 can scrape the inner wall of the reaction vessel 1, reducing the raw material accumulated on the inner wall of the reaction vessel 1.

[0020] like Figures 1 to 5 As shown, a limiting plate 31 is fixedly connected to the top of the reaction vessel 1. The limiting plate 31 is slidably connected to the first moving plate 17. A first fixing block 32 is fixedly connected to the top of the limiting plate 31. The first fixing block 32 is rotatably connected to the first screw 16. A second fixing block 33 is fixedly connected to the bottom of the reaction vessel 1. A sliding rod 34 is fixedly connected to the inner side of the second fixing block 33. The sliding rod 34 is slidably connected to the second moving plate 112. During operation, when the first moving plate 17 moves, it slides on the surface of the limiting plate 31. When the second moving plate 112 moves, it slides on the surface of the sliding rod 34. This step, by setting the limiting plate 31 and the first fixing block 32, can increase the stability when the first screw 16 rotates and the first moving plate 17 moves. By using the second fixing block 33 and the sliding rod 34, the stability when the second screw 111 rotates and the second moving plate 112 moves can be increased.

[0021] like Figure 2 As shown, a first heat insulation plate is fixedly connected to the surface of the reaction vessel 1, and the first heat insulation plate is fixedly connected to the first motor 15. A second heat insulation plate is fixedly connected to the bottom of the reaction vessel 1, and the second heat insulation plate is fixedly connected to the second motor 110. This step can provide heat insulation protection for the first motor 15 and the second motor 110 through the first heat insulation plate and the second heat insulation plate, and prevent the temperature of the first motor 15 and the second screw 111 from rising.

[0022] like Figure 3 As shown, a second scraper 51 is fixedly connected to the side of the stirring rod 22, and the bottom of the second scraper 51 is in contact with the inner wall of the reaction vessel 1. During operation, when the stirring rod 22 rotates, it drives the second scraper 51 to rotate. This step can scrape and clean the bottom wall of the reaction vessel 1 through the second scraper 51 to reduce the raw materials accumulated at the bottom.

[0023] like Figure 2 and Figure 3As shown, a drain valve 61 is fixedly connected to the bottom of the reaction vessel 1, and the drain valve 61 is connected to the heating tank 14. When condensate is generated inside the heating tank 14 during operation, it can be discharged through the drain valve 61. This step can discharge the condensate generated inside the heating tank 14 through the drain valve 61 to prevent the condensate accumulated inside the heating tank 14 from affecting the heating efficiency of the reaction vessel 1.

[0024] Working principle: The first motor 15 drives the first screw 16 to rotate, which in turn drives the first moving plate 17 to move. The first moving plate 17 then drives the first sealing plate 18 to move, which in turn drives the first heat insulation block 19 to move, separating it from the feed pipe 12. At this time, the raw material can be poured into the interior of the reaction tank 1 through the feed port on the side of the feed pipe 12. Heating gas is then injected into the interior of the heating tank 14 to heat the raw material inside the reaction tank 1. The first motor 15 then drives the first screw 16 to reverse, which in turn drives the first moving plate 17 to move downwards, and the first moving plate 17 then drives the first sealing plate 18 to move downwards, which in turn drives the first heat insulation block 19 to move. The sealing plate 18 moves, causing the first heat insulation block 19 to be inserted into the feed pipe 12. When the raw material is poured into the reaction tank 1, the third motor 21 drives the stirring rod 22 to rotate. The stirring rod 22 drives the first scraper 23 and the second scraper 51 to rotate. The stirring rod 22 and the first scraper 23 stir the raw material inside the reaction tank 1. When it is necessary to discharge the raw material, the second motor 110 drives the second screw 111 to rotate. The second screw 111 drives the second moving plate 112 to move to both sides, so that the second moving plate 112 is separated from the discharge valve 13. Then the discharge valve 13 can be opened to discharge the raw material inside the reaction tank 1.
