[0020] 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.

[0021] In actual use, due to the wide variety of reactor types and the different sizes of the feed inlets for each reactor, when the air knife blows air into the reactor, the amount of airflow entering the reactor is reduced, which in turn reduces the dehydration effect inside the reactor.

[0022] In view of this, the present invention provides a dehydration device for chemical reaction vessels, which solves the problem that in actual use, due to the wide variety of reaction vessels and the different sizes of the feed inlets of each type of reaction vessel, when the air knife blows air into the inside of the vessel, the airflow entering the reaction vessel is less, thus reducing the dehydration effect inside the reaction vessel.

[0023] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0024] Example 1: By Figure 1-5It is known that a chemical reactor dehydration device includes a mounting frame 1, an mounting plate 11 mounted on the upper outer wall of the mounting frame 1, a connecting pipe 12 rotatably connected to the inner wall of the mounting plate 11 via a sealed bearing, and an air outlet block 13 connected to the bottom of the connecting pipe 12. The chemical reactor dehydration device also includes a dehumidification device 2, a rotating device 3, a drying device 4, and a lifting device 5. The dehumidification device 2 is located on the outer wall of the air outlet block 13; the rotating device 3 is located above the outer wall of the connecting pipe 12; the drying device 4 is located at the top of the connecting pipe 12; and the lifting device 5 is located between the mounting plate 11 and the mounting frame 1. The dehumidification device 2 dehydrates the inside of the reactor, the rotating device 3 enables the dehumidification device 2 to rotate inside the reactor, the drying device 4 accelerates the evaporation of moisture inside the reactor, and the lifting device 5 ensures that the dehumidification device 2 can enter the reactor.

[0025] In the specific implementation process, it is worth noting that the shape of the mounting frame 1 is determined according to the actual situation, and the height of the mounting frame 1 is higher than the height of the reactor. The length and thickness of the connecting pipe 12 can be changed according to the size of the feed inlet at the top of the reactor. The lifting device 5 is used to extend the dehumidification device 2 into the reactor. The dehumidification device 2 dehydrates the inside of the reactor. When the dehumidification device 2 is working, the rotating device 3 can dehydrate the inside of the reactor more comprehensively. Through the action of the drying device 4, the gas entering the reactor has a certain temperature, which improves the dehydration rate inside the reactor.

[0026] Furthermore, the dehumidification device 2 includes an airbag tube 21, a nozzle 22, and a diaphragm 23. There are two airbag tubes 21, which are respectively connected to the two sides of the outer wall of the air outlet block 13. There are several nozzles 22, which are all connected to the bottom of the airbag tube 21. There are several diaphragms 23, which are all embedded in the inner wall of the air outlet block 13. Through the cooperation of the airbag tube 21 and the nozzle 22, the gas inside the air outlet block 13 is ejected, and the diaphragm 23 can protect the airbag tube 21.

[0027] In the specific implementation process, it is worth noting that the size of the air outlet block 13 meets the requirements of the feed inlet at the top of most reactors. When encountering a particularly small feed inlet, the air outlet block 13 can be replaced accordingly. Moreover, the replacement of the air outlet block 13 will not affect the opening of the air bladder tube 21. The air bladder tube 21 is made of rubber and can be folded when the air outlet block 13 enters the reactor to avoid affecting the insertion of the connecting pipe 12 and the air outlet block 13 into the reactor. When the internal gas pressure of the air outlet block 13 is too high, it will push open the diaphragm 23 to discharge the gas. It can also prevent the gas pressure inside the air bladder tube 21 from becoming too high, thus protecting it and extending the service life of the air bladder tube 21. Normal gas will be sprayed out through the nozzle 22 set on the surface of the air bladder tube 21, making the dehydration speed in the reactor faster.

[0028] Furthermore, the rotating device 3 includes a first servo motor 31, a driving gear 32, a driven gear 33, a protective shell 34, and a limiting plate 35. The first servo motor 31 is fixedly connected to the top of the mounting plate 11; the driving gear 32 is fixedly connected to the output end of the first servo motor 31; the driven gear 33 is fixedly connected to the outer wall of the connecting pipe 12 and meshes with the outer wall of the driving gear 32; the protective shell 34 is disposed on the outer wall of the driven gear 33 and fixedly connected to the top of the mounting plate 11, and its inner wall is rotatably connected to the first servo motor 31 via a sealed bearing. The output end of the servo motor 31; the limiting plate 35 is located below the mounting plate 11 and is fixedly connected to the outer wall of the connecting pipe 12; wherein, through the cooperation of the driving gear 32 and the driven gear 33, the first servo motor 31 drives the connecting pipe 12 to rotate, the limiting plate 35 can ensure the stability of the connecting pipe 12 when rotating, and the protective shell 34 can ensure the stability of the driving gear 32 and the driven gear 33 when rotating. The model of the first servo motor 31 is not limited, as long as it meets the actual use, and it is controlled by an external controller.

[0029] In the specific implementation process, it is worth noting that both the driving gear 32 and the driven gear 33 are bevel gears, and the size of the driving gear 32 is smaller, while the size of the driven gear 33 is larger than that of the driving gear 32. In this way, when the driving gear 32 rotates multiple times, the driven gear 33 rotates once, so that the rotation speed of the dehumidification device 2 in the reactor is not too fast, and the dehydration speed in the reactor is faster. In addition, the bottom of the limiting plate 35 is equipped with ball bearings, so that the limiting plate 35 can rotate with the connecting pipe 12.

[0030] Specifically, when using the dehydration device for this chemical reactor, during dehydration, a connecting pipe 12 and an air outlet block 13 corresponding to the reactor are selected. The mounting frame 1 is pushed near the reactor. Under the action of the lifting device 5, the dehumidification device 2 is raised. While it is being raised, the air bladder tube 21 is wrapped around the outer wall of the air outlet block 13 to prevent the connecting pipe 12 and the air outlet block 13 from being affected when inserted into the reactor. The mounting frame 1 is then pushed to align the air outlet block 13 and the connecting pipe 12 with the reactor's feed inlet. An external controller is used to control the lifting device 5, causing the mounting plate 11 to drive the dehumidification device 2 into the reactor. After insertion into the reactor, the air bladder tube 21 unfolds, and gas enters the air bladder tube 21 through the air outlet block 13. The nozzle 22 sprays out, causing rapid dehydration inside the reactor. When the gas pressure inside the gas bladder tube 21 is too high, the gas will push open the diaphragm 23, expelling the gas from the air outlet block 13, thus preventing damage caused by excessive pressure inside the gas bladder tube 21. During gas discharge, the first servo motor 31 is controlled to drive the drive gear 32 to rotate. Through the meshing of the drive gear 32 and the driven gear 33, the connecting pipe 12 rotates. When the connecting pipe 12 rotates, the limit plate 35 rotates as well, preventing instability during the rotation of the connecting pipe 12. Due to the different sizes of the drive gear 32 and the driven gear 33, the rotation speed of the connecting pipe 12 is slowed down. In this way, the dehumidification device 2 can evenly dehydrate the reactor, improving the dehydration efficiency of the reactor.

[0031] Example 2: From Figure 1-5 It is understood that the drying device 4 includes a blower 41, a heating box 42, a heating tube 43, and an air outlet pipe 44. The blower 41 is fixedly connected to the top of the mounting plate 11; the heating box 42 is connected to the output end of the blower 41 and is fixedly connected to the top of the mounting plate 11; the heating tube 43 is installed on the inner wall of the heating box 42; the air outlet pipe 44 is connected to the side of the heating box 42 away from the blower 41, and the end away from the heating box 42 is rotatably connected to the top of the protective shell 34 through a sealed bearing; wherein, through the cooperation of the heating tube 43 and the heating box 42, the air blown out by the blower 41 is heated, and the air outlet block 13 accelerates the reaction. For dehydration inside the reactor, the air outlet pipe 44 can connect the heating box 42 and the connecting pipe 12 together. The model of the heating pipe 43 is not limited, as long as it meets the actual use. The model of the blower 41 is also not limited. The external controller can control the blower 41 and the heating pipe 43 to heat separately. When dehydrating a small reactor, the blower 41 can be turned on directly without using the heating pipe 43. Dehydration inside the reactor can be carried out by simply increasing the gas flow rate. Conversely, when dehydrating a large reactor, the heating pipe 43 can be turned on to improve the dehydration efficiency.

[0032] In the specific implementation process, it is worth noting that, according to the size of the reactor, the controller is used to control the heating tube 43 to heat, and after the temperature in the heating box 42 rises, the blower 41 is used to send the heated gas into the air outlet block 13 through the air outlet pipe 44, and sprayed out by the air bag pipe 21 and the nozzle 22 to dehydrate the reactor. In order to ensure that the heating temperature is appropriate, additional structures such as temperature sensors can be configured to ensure that the heating temperature of the heating tube 43 is appropriate.

[0033] Furthermore, the lifting device 5 includes a fixed housing 51, a second servo motor 52, and a lead screw 53. The fixed housing 51 is fixedly connected to the top of the mounting frame 1 and movably connected to the outer wall of the mounting plate 11. The second servo motor 52 is fixedly connected to the top of the fixed housing 51. The lead screw 53 is fixedly connected to the output end of the second servo motor 52 and rotatably connected to the inner wall of the fixed housing 51 through a sealed bearing. The slider 54 is threadedly connected to the outer wall of the lead screw 53 and slidably engaged with the inner wall of the fixed housing 51, and is fixedly connected to the outer wall of the mounting plate 11 through the side wall opening of the fixed housing 51. The second servo motor 52 drives the mounting plate 11 to lift and lower through the cooperation of the lead screw 53 and the slider 54. The fixed housing 51 ensures the stability of the slider 54 during movement. The model of the second servo motor 52 is not limited, as long as it meets the actual usage requirements.

[0034] In the specific implementation process, it is worth noting that the second servo motor 52 is controlled by the controller and connected to the slider 54 by the screw 53. When the screw 53 rotates, it drives the slider 54 to move inside the fixed shell 51, and causes the mounting plate 11 to move the connecting pipe 12 and the air outlet block 13 out of the reactor. Moreover, the installation height of the fixed shell 51 is higher than the height of the reactor, so that the dehumidification device 2 can be inserted into the reactor without being limited by its height.

[0035] Specifically, based on the above embodiment, the controller controls the second servo motor 52 to work. The slider 54 is connected to the lead screw 53 by a thread, so that the slider 54 drives the mounting plate 11 to rise and fall, and inserts the dehumidification device 2 into the reactor. After the dehumidification device 2 is completely inserted into the reactor, the blower 41 and the heating tube 43 are controlled to work together to draw the hot air inside the heating box 42 into the connecting pipe 12 through the air outlet pipe 44, and then discharge it through the air outlet block 13 and the air bag pipe 21 to dehydrate the inside of the reactor. After dehydration, the second servo motor 52 is controlled to rotate in the opposite direction, so that the slider 54 drives the mounting plate 11 to rise and remove the dehumidification device 2 from the reactor.

[0036] It is worth noting that all of the above-mentioned reactors are equipped with discharge ports at the bottom, allowing the gas entering the reactor to be discharged through the discharge ports, and allowing the water droplets remaining on the inner wall to flow out through the discharge ports, thereby ensuring a better dehydration effect inside the reactor.
