Description

Technical Field

[0001] This utility model belongs to the field of reaction vessel technology, specifically relating to a reaction vessel for producing organotin catalysts. Background Technology

[0002] In the production of organotin catalysts, the stirring effect of the reactor directly affects product quality and production efficiency. Organotin catalysts typically have high viscosity, and traditional reactors use a single stirring method, which is insufficient to achieve thorough mixing of high-viscosity materials, easily leading to problems such as incomplete local reactions and uneven temperature distribution. In existing technologies, most reactors operate solely through simple revolution or rotation stirring, which cannot effectively overcome the viscous resistance of the material. Especially when processing high-viscosity systems, the stirring efficiency is low, energy consumption is high, and insufficient stirring may lead to a decrease in product purity. Utility Model Content

[0003] The purpose of this invention is to provide a reaction vessel for producing organotin catalysts, which can effectively stir organotin catalysts with high viscosity through three stirring methods.

[0004] The specific technical solution adopted by this utility model is as follows:

[0005] A reactor for producing organotin catalysts includes a reactor body, a rotating support installed inside the reactor body, a plurality of stirring elements installed around the rotating support, and a primary kinetic energy conversion group and a secondary kinetic energy conversion group connected by the stirring elements installed inside the reactor body.

[0006] The rotating support is used to drive multiple stirring components to revolve inside the reactor body. The first-stage kinetic energy conversion group recovers the kinetic energy of the stirring components during their revolution to drive the stirring components to rotate. The second-stage kinetic energy conversion group recovers the kinetic energy of the stirring components during their revolution to drive the stirring components to move up and down repeatedly.

[0007] Furthermore, the rotating support includes a drive motor fixedly connected to the upper end of the reactor body. The output end of the drive motor is drivenly connected to a main shaft. The main shaft is rotatably connected to the middle position of the reactor body. Two support bodies are fixedly connected to the outer side of the main shaft. Multiple connecting pipes are rotatably connected to the periphery of each of the two support bodies. The connecting pipes on the two support bodies are paired one-to-one as a group. The stirring element is vertically slidably connected to two connecting pipes in the same group. The primary kinetic energy conversion group and the connecting pipes are drivenly connected.

[0008] Furthermore, the primary kinetic energy conversion group includes a toothed ring fixedly connected to the inner side of the reactor body, the toothed ring being meshed with multiple meshing gears, and the multiple meshing gears being fixedly connected to the outer side of multiple connecting pipes respectively.

[0009] Furthermore, the secondary kinetic energy conversion assembly includes an annular connecting ring, round rods, an annular ring, and a guide groove. The upper ends of multiple stirring components are rotatably connected to the annular connecting ring. There are multiple round rods, which are fixedly connected to the periphery of the annular connecting ring in an annular array. The annular ring is fixedly connected to the upper side inside the reactor body. The guide groove is opened on the annular ring, and the round rods are slidably connected inside the guide groove.

[0010] Furthermore, the stirring component includes a rotating rod, the upper end of which is rotatably connected to an annular connecting ring. The rotating rod is vertically slidably connected inside the connecting pipe. Multiple spiral blades and multiple sets of pusher plates are fixedly connected to the outer side of the rotating rod, and the spiral blades and pusher plates are arranged at intervals.

[0011] Furthermore, the guide groove includes a plurality of first inclined grooves and a plurality of second inclined grooves, the plurality of first inclined grooves and second inclined grooves being arranged at intervals, and the first inclined grooves and second inclined grooves being connected in sequence.

[0012] Furthermore, an inner liner is fixedly connected to the inner side of the reactor body. The reactor body is made of stainless steel, and the inner liner is made of polytetrafluoroethylene or a glass coating.

[0013] Furthermore, a feed pipe is fixedly connected to the upper end of the reactor body, and a discharge pipe is fixedly connected to the lower end of the reactor body.

[0022] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0023] like Figures 1-4 As shown, a reactor for producing organotin catalysts includes a reactor body 1, a feed pipe 2 fixedly connected to the upper end of the reactor body 1, and a discharge pipe 3 fixedly connected to the lower end of the reactor body 1. The organotin catalyst raw material enters the reactor body 1 through the feed pipe 2, and is stirred and heated inside the reactor body 1 to cause the raw material to react and form organotin catalyst. Then, the valve installed on the discharge pipe 3 is opened to discharge the organotin catalyst.

[0024] Meanwhile, an inner liner 4 can be fixedly connected to the inner side of the reactor body 1. The reactor body 1 can be made of stainless steel, and the inner liner 4 can be made of polytetrafluoroethylene or glass coating. Polytetrafluoroethylene has excellent chemical stability and is resistant to strong acids, strong alkalis and organic solvent corrosion; the glass coating can provide a smooth surface, prevent material adhesion and facilitate cleaning.

[0025] The core of this technical solution lies in the improvement of the stirring mechanism inside the reactor. Specifically, a rotating support is installed inside the reactor body 1, and multiple stirring components are installed around the rotating support. A primary kinetic energy conversion group and a secondary kinetic energy conversion group are installed inside the reactor body 1, which are connected by the stirring components.

[0026] The rotating support is used to drive multiple stirring components to revolve inside the reactor body 1 and rotate around the central axis of the reactor body 1. The first-level kinetic energy conversion group recovers the kinetic energy of the stirring components during their revolution to drive the stirring components to rotate on their own axis. The second-level kinetic energy conversion group recovers the kinetic energy of the stirring components during their revolution to drive the stirring components to move up and down repeatedly.

[0027] In operation, the rotating support is activated to drive multiple agitators to revolve inside the reactor body 1. The revolving agitators perform primary agitation of the raw materials inside the reactor body 1. Then, the primary kinetic energy conversion group recovers the kinetic energy of the agitators during their revolution to drive the agitators to rotate on their own axis. The rotating agitators perform secondary agitation of the raw materials inside the reactor body 1. The secondary kinetic energy conversion group then recovers the kinetic energy of the agitators during their revolution to drive the agitators to move up and down repeatedly. The repeated up and down movement of the agitators pushes the raw materials up and down, thus forming tertiary agitation. By using the agitators to agitate the organotin catalyst raw materials in three ways, the high viscosity organotin catalyst can be effectively agitated.

[0028] Among them, such as Figures 2-4 As shown, the rotating support includes a drive motor 5 fixedly connected to the upper end of the reactor body 1. The output end of the drive motor 5 is driven by a main shaft 6. The main shaft 6 is rotatably connected to the middle position of the reactor body 1. By starting the drive motor 5, the main shaft 6 can be driven to rotate. Two support bodies 7 are fixedly connected to the outside of the main shaft 6. Multiple connecting pipes 8 are rotatably connected to the periphery of each of the two support bodies 7. The connecting pipes 8 on the two support bodies 7 are paired one-to-one as a group. The stirring element is vertically slidably connected to the two connecting pipes 8 in the same group. The primary kinetic energy conversion group is driven by the connecting pipes 8. By driving the connecting pipes 8 to rotate through the primary kinetic energy conversion group, the stirring element on the connecting pipes 8 can be made to rotate.

[0029] like Figures 2-4 As shown, the primary kinetic energy conversion unit includes a toothed ring 11 fixedly connected to the inner side of the reactor body 1. The toothed ring 11 is meshed with multiple gears 9, which are fixedly connected to the outer sides of multiple connecting pipes 8. During the revolution of the connecting pipes 8, the gears 9 on the outer side of the connecting pipes 8 move on the toothed ring 11. Since the gears 9 and the toothed ring 11 are meshed, the gears 9 rotate during the movement, inputting rotational kinetic energy into the connecting pipes 8. Its structure is relatively simple.

[0030] like Figures 2-4As shown, the secondary kinetic energy conversion group includes an annular connecting ring 14, a round rod 15, an annular ring 16, and a guide groove 17. The upper ends of multiple stirring components are rotatably connected to the annular connecting ring 14. There are multiple round rods 15, which are fixedly connected to the periphery of the annular connecting ring 14 in an annular array. The annular ring 16 is fixedly connected to the upper side inside the reactor body 1. The guide groove 17 is opened on the annular ring 16. The guide groove 17 includes multiple first inclined grooves and multiple second inclined grooves. The multiple first inclined grooves and second inclined grooves are arranged at intervals and are connected sequentially. The round rod 15 is slidably connected inside the guide groove 17. At this time, during the process of multiple stirring components driving the annular connecting ring 14 to rotate, the round rod 15 on the outside of the annular connecting ring 14 moves inside the guide groove 17, so that the annular connecting ring 14 can move up and down repeatedly. Thus, the sliding of the round rod 15 in the guide groove 17 is converted into up and down kinetic energy, and the up and down kinetic energy is input to the stirring components.

[0031] Among them, such as Figures 2-4 As shown, the mixing component includes a rotating rod 10, the upper end of which is rotatably connected to an annular connecting ring 14. The rotating rod 10 is vertically slidably connected inside the connecting pipe 8. Multiple spiral blades 12 and multiple sets of pusher plates 13 are fixedly connected to the outside of the rotating rod 10. The spiral blades 12 and pusher plates 13 are arranged at intervals, and the height of the spiral blades 12 and pusher plates 13 is the same as the height of the vertical movement of the rotating rod 10. The vertical movement of the rotating rod 10 can drive the spiral blades 12 and pusher plates 13 to process the raw materials at the same height in sequence. The toothed ring 11 can apply a vertical thrust to the raw materials, and the pusher plates 13 can apply a horizontal thrust to the raw materials, thereby effectively applying both horizontal and vertical thrust to the raw materials, making the raw materials more evenly mixed.

[0032] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
