Technical Field

[0001] This utility model relates to the field of flame retardant synthesis technology, specifically to a high-efficiency baffle plate stirring device for a flame retardant synthesis reactor. Background Technology

[0002] Liquid flame retardants are chemical substances or materials that can reduce the burning rate and reduce the spread of fire. They are functional additives that give flammable polymers flame-retardant properties. During the synthesis and processing of flame retardants, they need to be stirred, so stirring devices are required.

[0003] For example, the utility model application with application number 202320932714.0 discloses a mixing tank mixing baffle device for a premix production line. Similar mixing devices have the following shortcomings: although they can baffle and mix liquid materials, after long-term use, the surface of the baffle structure is prone to scale buildup and is not easy to clean, and the disassembly and cleaning method is quite troublesome. Utility Model Content

[0004] The purpose of this invention is to provide a high-efficiency baffle plate stirring device for a flame retardant synthesis reactor, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency baffle stirring device for a flame retardant synthesis reactor, comprising a stirring vessel, a baffle assembly, and a cleaning assembly. The baffle assembly is fixed to the inner wall of the stirring vessel, and the cleaning assembly is installed on the outer side of the baffle assembly. The cleaning assembly includes an outer scraper, a connecting scraper, and a fixed connecting rod. The outer scrapers are connected to each other, and a fixed connecting rod is welded to one side of one of the connecting scrapers. A driving assembly is installed on the outer side of the stirring vessel, and the driving assembly includes a fixed frame, a driving motor, a lead screw, a movable sleeve, and a connecting block. The driving motor is installed below the fixed frame, and a lead screw is rotatably arranged inside the fixed frame. A movable sleeve is sleeved on the outer side of the lead screw, and a connecting block is fixed to one side of the movable sleeve. The connecting block and the fixed connecting rod are fixedly connected.

[0006] Furthermore, the baffle assembly includes a porous baffle plate and through holes. The porous baffle plate has through holes evenly spaced on its surface, and the porous baffle plate is evenly distributed in ten groups in an array about the center line of the stirred tank.

[0007] Furthermore, the baffle assembly also includes side baffles, with side baffles symmetrically fixed on both sides of the porous baffle, and the side baffles having an inclined structure.

[0008] Furthermore, the shape of the outer scraper matches the shape of the porous baffle and the side baffle, and the outer scraper is also evenly distributed in an array of ten.

[0009] Furthermore, the connecting scraper has an arc-shaped structure and is attached to the inner wall of the mixing vessel.

[0010] Furthermore, a central rotating shaft is rotatably arranged inside the mixing vessel, and stirring blades are fixed on the outer side of the central rotating shaft. A discharge pipe is connected to the lower middle part of the mixing vessel.

[0011] Furthermore, a lid is installed on the upper side of the mixing vessel, and a feed pipe is connected to one side of the lid. A rotary motor is installed at the top of the central rotating shaft, and the rotary motor is located above the lid.

[0012] Furthermore, the movable sleeve is slidably connected to the inner wall of the fixed frame, while the fixed connecting rod passes through the lid and is slidably connected to the lid up and down.

[0013] This invention provides a high-efficiency baffle plate stirring device for a flame retardant synthesis reactor, which has the following advantages:

[0014] This utility model is equipped with a cleaning component. The drive motor facilitates the rotation of the lead screw, which in turn drives the outer moving sleeve of the lead screw to move up and down. The moving sleeve drives the fixed connecting rod, the outer scraper, and the connecting scraper to move up and down through the connecting block. The shape of the outer scraper matches the shape of the porous baffle and the side baffle, so that the outer scraper cleans the surface of the porous baffle and the side baffle from top to bottom. At the same time, the arc-shaped connecting scraper cleans the inner wall of the mixing vessel from top to bottom.

[0015] This invention features a baffle assembly. A rotary motor facilitates the rotation of the central shaft and stirring blades, enabling the stirring blades to synthesize and stir the liquid flame retardant inside the mixing vessel. At this time, the inner wall of the mixing vessel is uniformly distributed with porous baffles and side baffles in an array, allowing the liquid flame retardant to impact and collide with several porous baffles and side baffles to improve the mixing efficiency. The side baffles have an inclined structure, allowing the liquid flame retardant impacting the porous baffles to impact another adjacent baffle assembly along the inclined surface of the side baffles, thereby enhancing the turbulence effect.

[0021] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0022] like Figures 1-2 As shown, a high-efficiency baffle stirring device for a flame retardant synthesis reactor includes a stirring vessel 1, a baffle assembly 2, and a cleaning assembly 3. The inner wall of the stirring vessel 1 is fixed with the baffle assembly 2, which includes porous baffles 201 and through holes 202. Through holes 202 are evenly spaced on the surface of the porous baffles 201, and ten sets of porous baffles 201 are evenly distributed in an array about the center line of the stirring vessel 1. The baffle assembly 2 also includes side baffles 203, which are symmetrically fixed on both sides of the porous baffles 201 and are inclined. A central rotating shaft 4 is rotatably installed in the middle of the stirring vessel 1, and stirring blades 5 are fixed to the outer side of the central rotating shaft 4. A discharge pipe 10 is connected to the lower middle part of the stirring vessel 1, and a stirring blade 5 is installed on the upper side of the stirring vessel 1. The vessel has a lid 6, and a feed pipe 8 is connected to one side of the lid 6. A rotary motor 7 is installed at the top of the central rotating shaft 4, and the rotary motor 7 is located above the lid 6. The rotary motor 7 facilitates the rotation of the central rotating shaft 4 and the stirring blades 5, so that the stirring blades 5 can synthesize and stir the liquid flame retardant inside the stirring vessel 1. At this time, the inner wall of the stirring vessel 1 has a porous baffle 201 and a side baffle 203 evenly distributed in an array, so that the liquid flame retardant can impact and collide with several porous baffles 201 and side baffles 203 to improve the mixing efficiency. The side baffles 203 have an inclined structure so that the liquid flame retardant impacting the porous baffles 201 can impact the adjacent baffle assembly 2 along the inclined surface of the side baffles 203 to enhance the turbulence effect.

[0023] like Figure 1 , Figure 3 and Figure 4As shown, a cleaning component 3 is installed on the outside of the baffle assembly 2. The cleaning component 3 includes an outer scraper 301, a connecting scraper 302, and a fixing rod 303. The connecting scrapers 302 are connected between the outer scrapers 301. A fixing rod 303 is welded to one side of one of the connecting scrapers 302. The shape of the outer scrapers 301 matches the shape of the porous baffle 201 and the side baffle 203. Ten outer scrapers 301 are also evenly distributed in an array. 302 has an arc-shaped structure, and the connecting scraper 302 is attached to the inner wall of the mixing vessel 1. A drive assembly 9 is installed on the outer side of the mixing vessel 1. The drive assembly 9 includes a fixed frame 901, a drive motor 902, a lead screw 903, a movable sleeve 904, and a connecting block 905. The drive motor 902 is installed below the fixed frame 901, and the lead screw 903 is rotatably mounted inside the fixed frame 901. The movable sleeve 904 is sleeved on the outer side of the lead screw 903. A connecting block 905 is fixed on one side of 04, and the connecting block 905 is fixedly connected to the fixed connecting rod 303. The movable sleeve 904 is slidably connected to the inner wall of the fixed frame 901. At the same time, the fixed connecting rod 303 passes through the kettle cover 6 and is slidably connected to the kettle cover 6. The drive motor 902 facilitates the rotation of the lead screw 903, so as to drive the movable sleeve 904 on the outside of the lead screw 903 to move up and down. The movable sleeve 904 drives the fixed connecting rod 303, the outer scraper 301 and the connecting scraper 302 to move up and down through the connecting block 905. The shape of the outer scraper 301 matches the shape of the porous baffle 201 and the side baffle 203, so that the outer scraper 301 cleans the surface of the porous baffle 201 and the side baffle 203 from top to bottom. At the same time, the arc-shaped connecting scraper 302 cleans the inner wall of the mixing kettle 1 from top to bottom, avoiding the problem that the inner wall of the mixing kettle 1 with the baffle structure is difficult to clean and easy to accumulate scale.

[0024] In summary, as Figures 1-4As shown, the flame retardant synthesis reactor uses a high-efficiency baffle stirring device. In use, the flame retardant synthesis material is first fed into the reactor 1 through the feed pipe 8. Then, the rotation of the central shaft 4 and stirring blades 5 is driven by the rotary motor 7, allowing the stirring blades 5 to synthesize and stir the liquid flame retardant inside the reactor 1. At this time, the liquid flame retardant impacts and collides with several porous baffles 201 and side baffles 203 to improve the mixing efficiency. The side baffles 203 have an inclined structure, allowing the liquid flame retardant impacting the porous baffles 201 to impact another adjacent baffle assembly 2 along the inclined surface of the side baffles 203, thus enhancing the turbulence effect. During use, the device can also be driven by the motor... 902 drives the rotation of the lead screw 903, which in turn drives the outer moving sleeve 904 of the lead screw 903 to move up and down. This causes the moving sleeve 904 to drive the fixed connecting rod 303, the outer scraper 301, and the connecting scraper 302 to move up and down through the connecting block 905. The shape of the outer scraper 301 matches the shape of the porous baffle 201 and the side baffle 203, thus allowing the outer scraper 301 to clean the surfaces of the porous baffle 201 and the side baffle 203 from top to bottom. At the same time, the arc-shaped connecting scraper 302 cleans the inner wall of the mixing vessel 1 from top to bottom. Finally, the valve at the discharge pipe 10 is opened to discharge the material through the discharge pipe 10. This completes the use of the high-efficiency baffle stirring device for the flame retardant synthesis reactor.
