Abstract
Description
Technical Field
[0001] This utility model belongs to the field of reaction vessel technology, and specifically relates to a safe reaction vessel. Background Technology
[0002] A reaction vessel is a container used for chemical reactions or physical mixing. It is widely used in many industries such as chemical, pharmaceutical, food, dye, metallurgy, and environmental protection. Safety standards and specifications should be strictly followed in the design, manufacture, and use of reaction vessels to ensure the safety of operators and equipment.
[0003] During the use of a reactor, after the reaction of materials is completed, the inside of the reactor needs to be cleaned. During cleaning, clean water or cleaning solution is usually injected into the reactor and the reactor's agitator is used to stir and clean the inside of the reactor. However, for the deposits attached to the inner wall of the reactor, it is difficult to quickly remove them by simply stirring and rotating the water. It is also necessary to open the top cover of the reactor and use cleaning brushes and other tools for cleaning, which is very inconvenient. Utility Model Content
[0004] To address the above problems, the purpose of this utility model is to provide a safe reaction vessel. By setting up an adjustable first stirring and scraping integrated plate and a second stirring and scraping integrated plate, it can not only perform stirring functions, but also scrape off the remaining deposits on the inner wall of the reaction vessel body during cleaning, thereby effectively improving the cleaning efficiency and effect of the reaction vessel body.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a safe reaction vessel, comprising a reaction vessel body, a top cover on the top of the reaction vessel body, a bracket mounted on the top of the top cover, a first motor mounted on the top of the bracket, the top cover and a hollow rotating shaft being rotatably connected via a sealed bearing, the output end of the first motor being connected to a first gear, a second gear being sleeved on the outer side of the top of the hollow rotating shaft, the first gear and the second gear meshing with each other, a stirring and scraping integrated device being installed on the side of the hollow rotating shaft, the stirring and scraping integrated device comprising a first telescopic sleeve and a second telescopic sleeve installed on the side of the hollow rotating shaft, a third telescopic sleeve being connected to the bottom of the second telescopic sleeve, a first telescopic rod being inserted and installed inside the first telescopic sleeve, a second telescopic rod being inserted and installed inside the second telescopic sleeve, and a third telescopic rod being inserted and installed inside the third telescopic sleeve, one end of the first telescopic rod and the second telescopic rod being connected to a first stirring and scraping mechanism, one end of the third telescopic rod being connected to a second stirring and scraping mechanism, and a transmission mechanism being installed inside the hollow rotating shaft, the second telescopic sleeve, and the third telescopic sleeve.
[0006] The beneficial effects of this utility model are as follows: When this device is in use, during the reaction of materials inside the reactor body, the first motor drives the first gear to rotate, which in turn drives the second gear and the hollow rotating shaft to rotate, thereby driving the first and second integrated stirring and scraping plates to rotate, stirring the materials in the reactor body. After the materials are discharged, when it is necessary to clean the inside of the reactor body, cleaning water and cleaning solution can be injected into the reactor body through the injection pipe. By rotating the rotating shaft with a rocker arm, the first bevel gear drives the second bevel gear and the first screw to rotate. The rotation of the first screw drives the third bevel gear to rotate, which in turn drives the fourth bevel gear and the second screw to rotate. The synchronous rotation of the first and second screws drives the second and third telescopic rods to move synchronously. The movement of the second telescopic rod drives the first fixed frame and the first integrated stirring and scraping plate to move in the first telescopic sleeve and the first telescopic... With the cooperation of the rod, the second stirring and scraping integrated plate moves towards the inner side wall of the reactor body. At the same time, the third telescopic rod also drives the second stirring and scraping integrated plate to move diagonally downward with the limiting and anti-rotation function of the first stirring and scraping integrated plate, so that the second stirring and scraping integrated plate contacts the inner side wall and bottom inner wall of the reactor body. At this time, the first motor is controlled to run, which drives the hollow rotating shaft to drive the first stirring and scraping integrated plate and the second stirring and scraping integrated plate to rotate, scraping off the remaining deposits on the inner wall of the reactor body, thereby effectively improving the cleaning efficiency and effect inside the reactor body. After cleaning is completed, the discharge control valve can be opened to discharge the cleaned wastewater. Then, the rocker arm can be rotated in the opposite direction to drive the first stirring and scraping integrated plate and the second stirring and scraping integrated plate to reset and disengage from the inner wall of the reactor body. In this way, when the reactor body is carrying out material reaction, the first stirring and scraping integrated plate and the second stirring and scraping integrated plate will not contact the reactor body during stirring, avoiding wear.
[0007] For material refilling:
[0008] As a further improvement to the above technical solution: the top of the top cover is connected to a filling pipe, and a feed control valve is installed in the middle section of the filling pipe.
[0009] The beneficial effects of this improvement are as follows: When using this device, materials are added to the interior of the reactor body through the filling pipe. After the filling is completed, the feed control valve can be closed.
[0010] For the control of material discharge from the main body of the reactor:
[0011] As a further improvement to the above technical solution: a discharge pipe is installed at the bottom of the main body of the reactor, and a discharge control valve is installed at the bottom of the discharge pipe.
[0012] The beneficial effect of this improvement is that the material in the reactor body can be discharged by opening the discharge control valve.
[0013] To ensure safety by releasing pressure when it becomes too high:
[0014] As a further improvement to the above technical solution: the top mounting rod of the top cover has a pressure sensor and a pressure relief valve.
[0015] The beneficial effects of this improvement are: during the reaction, the pressure sensor detects the pressure in the main body of the reactor in real time, and when the pressure is too high, it can be relieved through the pressure relief valve.
[0016] As a further improvement to the above technical solution: the first stirring scraper mechanism includes a first fixed frame connected to the first telescopic rod and the second telescopic rod, and a first stirring and scraping integrated plate is installed on the inner side of the first fixed frame; the second stirring scraper mechanism includes a second fixed frame connected to one end of the third telescopic rod, and a second stirring and scraping integrated plate is installed on the inner side of the second fixed frame.
[0017] To limit the movement of the second integrated mixing and scraping plate:
[0018] As a further improvement to the above technical solution: the first integrated stirring and scraping plate consists of two pieces, located on both sides of the second integrated stirring and scraping plate.
[0019] The beneficial effects of this improvement are: the first integrated stirring and scraping plate on both sides of the second integrated stirring and scraping plate plays a limiting role, preventing it and the third telescopic rod from rotating with the second screw.
[0020] To drive the first and second integrated stirring and scraping plates to move:
[0021] As a further improvement to the above technical solution: the transmission mechanism includes a rotating shaft rotatably mounted inside a hollow rotating shaft, one end of the rotating shaft being connected to a first bevel gear, a first screw rotatably mounted inside the second telescopic rod, a second screw rotatably mounted inside the third telescopic sleeve, a second bevel gear mounted at one end of the first screw, the first bevel gear and the second bevel gear meshing with each other, a third bevel gear sleeved on the outside of the first screw, a fourth bevel gear mounted on the top of the second screw, the third bevel gear and the fourth bevel gear meshing with each other, a threaded connection between the first screw and the second telescopic rod, a threaded connection between the second screw and the third telescopic rod, and a rocker arm connected to the top of the rotating shaft.
[0022] The beneficial effects of this improvement are as follows: By rotating the shaft with a rocker arm, the first bevel gear drives the second bevel gear and the first screw to rotate. The rotation of the first screw simultaneously drives the third bevel gear to rotate, and the third bevel gear drives the fourth bevel gear and the second screw to rotate. The synchronous rotation of the first and second screws drives the second and third telescopic rods to move synchronously. The movement of the second telescopic rod drives the first fixed frame and the first integrated stirring and scraping plate to move towards the inner side wall of the reactor body with the cooperation of the first telescopic sleeve and the first telescopic rod. At the same time, the third telescopic rod also drives the second integrated stirring and scraping plate to move diagonally downward with the limiting and anti-rotation effect of the first integrated stirring and scraping plate, so that the second integrated stirring and scraping plate contacts the inner side wall and the bottom inner wall of the reactor body.

Detailed Implementation
[0030] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.
[0031] like Figure 1-5 As shown, a safety reactor includes a reactor body 1, a top cover 2 on the top of the reactor body 1, a bracket 7 mounted on the top of the top cover 2, a first motor 8 mounted on the top of the bracket 7, the top cover 2 and a hollow rotating shaft 9 being rotatably connected via a sealed bearing, the output end of the first motor 8 being connected to a first gear 27, a second gear 28 being sleeved on the outer side of the top of the hollow rotating shaft 9, the first gear 27 and the second gear 28 meshing with each other, and a stirring and scraping integrated device being installed on the side of the hollow rotating shaft 9, the stirring and scraping integrated device including a first telescopic sleeve installed on the side of the hollow rotating shaft 9. 10. A second telescopic sleeve 12, the bottom of which is connected to a third telescopic sleeve 14. A first telescopic rod 11 is inserted into the inner side of the first telescopic sleeve 10, a second telescopic rod 13 is inserted into the inner side of the second telescopic sleeve 12, and a third telescopic rod 15 is inserted into the inner side of the third telescopic sleeve 14. One end of the first telescopic rod 11 and the second telescopic rod 13 is connected to a first stirring scraper mechanism, and one end of the third telescopic rod 15 is connected to a second stirring scraper mechanism. A transmission mechanism is installed inside the hollow rotating shaft 9, the second telescopic sleeve 12, and the third telescopic sleeve 14.
[0032] During the operation of this device, while the material is reacting inside the reactor body 1, the first motor 8 drives the first gear 27 to rotate, which in turn drives the second gear 28, along with the hollow rotating shaft 9, to rotate. This, in turn, rotates the first stirring and scraping integrated plate 18 and the second stirring and scraping integrated plate 19, thus stirring the material in the reactor body 1. After the material is discharged, when it is necessary to clean the inside of the reactor body 1, cleaning water and cleaning solution can be injected into the inside of the reactor body 1 through the injection pipe 3. The rocker arm 31 is then rotated. The rotating shaft 20 drives the second bevel gear 24 and the first screw 22 to rotate via the first bevel gear 21. Simultaneously, the rotation of the first screw 22 drives the third bevel gear 29 to rotate. The third bevel gear 29 drives the fourth bevel gear 30 and the second screw 23 to rotate. The synchronous rotation of the first screw 22 and the second screw 23 drives the second telescopic rod 13 and the third telescopic rod 15 to move synchronously. The movement of the second telescopic rod 13 drives the first fixed frame 16 and the first integrated stirring and scraping plate 18 to move synchronously along the first telescopic sleeve 10. With the cooperation of the telescopic rod 11, the second stirring and scraping integrated plate 19 moves towards the inner side wall of the reactor body 1. At the same time, the third telescopic rod 15 also drives the second stirring and scraping integrated plate 19 to move diagonally downward with the limiting and anti-rotation function of the first stirring and scraping integrated plate 18, so that the second stirring and scraping integrated plate 19 contacts the inner side wall and bottom inner wall of the reactor body 1. At this time, controlling the first motor 8 to run can drive the hollow rotating shaft 9 to drive the first stirring and scraping integrated plate 18 and the second stirring and scraping integrated plate 19 to rotate, and scrape the remaining residue on the inner wall of the reactor body 1. The attached substances are scraped off, thereby effectively improving the cleaning efficiency and effect inside the reactor body 1. After cleaning, the discharge control valve 6 can be opened to discharge the cleaned wastewater. Then, the rocker arm 31 can be rotated in the opposite direction to drive the first stirring and scraping integrated plate 18 and the second stirring and scraping integrated plate 19 to reset and disengage from the inner wall of the reactor body 1. In this way, when the reactor body 1 is carrying out material reaction, the first stirring and scraping integrated plate 18 and the second stirring and scraping integrated plate 19 will not come into contact with the reactor body 1 during stirring, thus avoiding wear.
[0033] The top of the top cover 2 is connected to a filling pipe 3, and a feed control valve 4 is installed in the middle section of the filling pipe 3.
[0034] When using this device, materials are added to the interior of the reactor body 1 through the filling pipe 3. After the filling is completed, the feed control valve 4 can be closed.
[0035] A discharge pipe 5 is installed at the bottom of the reactor body 1, and a discharge control valve 6 is installed at the bottom of the discharge pipe 5.
[0036] Opening the discharge control valve 6 will discharge the material from the reactor body 1.
[0037] The top mounting rod of the top cover 2 has a pressure sensor 25 and a pressure relief valve 26.
[0038] During the reaction, the pressure sensor 25 monitors the pressure in the reactor body 1 in real time. When the pressure is too high, it can be relieved through the pressure relief valve 26.
[0039] The first stirring scraper mechanism includes a first fixing frame 16 connected to the first telescopic rod 11 and the second telescopic rod 13. A first stirring and scraping integrated plate 18 is installed on the inner side of the first fixing frame 16. The second stirring scraper mechanism includes a second fixing frame 17 connected to one end of the third telescopic rod 15. A second stirring and scraping integrated plate 19 is installed on the inner side of the second fixing frame 17.
[0040] The first integrated stirring and scraping plate 18 consists of two pieces, located on both sides of the second integrated stirring and scraping plate 19.
[0041] The first mixing and scraping integrated plate 18 serves to limit the second mixing and scraping integrated plate 19 on both sides, preventing it and the third telescopic rod 15 from rotating along with the second screw 23.
[0042] The transmission mechanism includes a rotating shaft 20 rotatably mounted inside a hollow rotating shaft 9. One end of the rotating shaft 20 is connected to a first bevel gear 21. A first screw 22 is rotatably mounted inside the second telescopic rod 13. A second screw 23 is rotatably mounted inside the third telescopic sleeve 14. A second bevel gear 24 is mounted at one end of the first screw 22. The first bevel gear 21 and the second bevel gear 24 mesh with each other. A third bevel gear 29 is sleeved on the outside of the first screw 22. A fourth bevel gear 30 is mounted on the top of the second screw 23. The third bevel gear 29 and the fourth bevel gear 30 mesh with each other. The first screw 22 is threadedly connected to the second telescopic rod 13. The second screw 23 is threadedly connected to the third telescopic rod 15. A rocker arm 31 is connected to the top of the rotating shaft 20.
[0043] The working principle and usage process of this utility model are as follows: When using this device, materials are added to the interior of the reactor body 1 through the filling pipe 3. After filling, the feed control valve 4 is closed. During the reaction of the materials inside the reactor body 1, the first motor 8 drives the first gear 27 to rotate, which in turn drives the second gear 28, along with the hollow rotating shaft 9, to rotate. This, in turn, rotates the first stirring and scraping integrated plate 18 and the second stirring and scraping integrated plate 19, stirring the materials in the reactor body 1. During the reaction, the pressure sensor 25 monitors the pressure in the reactor body 1 in real time. When the pressure is too high, the pressure relief valve 26 can be used to release the pressure. After depressurization and completion of the reaction, the discharge control valve 6 is opened to discharge the material inside the reactor body 1 through the discharge pipe 5. When cleaning the interior of the reactor body 1 is required after material discharge, cleaning water and cleaning solution are injected into the reactor body 1 through the injection pipe 3. Rotating the rotating shaft 20 via the rocker arm 31 drives the first bevel gear 21, which in turn drives the second bevel gear 24 and the first screw 22 to rotate. Simultaneously, the rotation of the first screw 22 drives the third bevel gear 29 to rotate, which in turn drives the fourth bevel gear 30 and the second screw 23 to rotate. The synchronous rotation of the first screw 22 and the second screw 23 drives the second telescopic... The second telescopic rod 13 and the third telescopic rod 15 move synchronously. The movement of the second telescopic rod 13 drives the first fixed frame 16, together with the first integrated stirring and scraping plate 18, to move towards the inner side wall of the reactor body 1 under the cooperation of the first telescopic sleeve 10 and the first telescopic rod 11. Simultaneously, the third telescopic rod 15 also drives the second integrated stirring and scraping plate 19, with the limiting and anti-rotation function of the first integrated stirring and scraping plate 18, to move diagonally downwards, so that the second integrated stirring and scraping plate 19 contacts the inner side wall and bottom inner wall of the reactor body 1. At this time, controlling the first motor 8 to run drives the hollow rotating shaft 9 to move the first integrated stirring and scraping plate 18 and the second integrated stirring and scraping plate 19. The rotating integrated plate 19 scrapes away the remaining deposits on the inner wall of the reactor body 1, thereby effectively improving the cleaning efficiency and effect inside the reactor body 1. The scraped deposits settle at the bottom of the reactor body 1. After cleaning, the discharge control valve 6 can be opened to discharge the wastewater. Then, the rocker arm 31 can be rotated in the opposite direction to drive the first stirring and scraping integrated plate 18 and the second stirring and scraping integrated plate 19 to reset and disengage from the inner wall of the reactor body 1. In this way, when the reactor body 1 is undergoing material reaction, the first stirring and scraping integrated plate 18 and the second stirring and scraping integrated plate 19 will not come into contact with the reactor body 1 during stirring, thus avoiding wear.
