Description
Technical Field
[0001] This utility model relates to the field of flame retardant production technology, and in particular to a stirring device for flame retardant production. Background Technology
[0002] Flame retardants are special chemical substances, also known as fire-retardant agents, fire-resistant agents, or flame-retardant retardants. They effectively improve the flame retardancy of combustible or flammable materials, preventing raw materials from being ignited and controlling the spread of flames. Flame retardants are mainly used in the flame-retardant treatment of polymer materials. Materials treated with flame retardants can effectively prevent, delay, or terminate the spread of flames when attacked by external fire sources, thus achieving a flame-retardant effect. The production of flame retardants requires the use of a stirring device.
[0003] Current mixing devices, during installation and use by users, still have the following shortcomings:
[0004] (1) Most existing stirring devices only have a single stirring blade, which makes the raw materials in the reactor not mixed evenly, thus affecting the reaction between the raw materials. This may not only result in the production of substandard flame retardants, but also waste a lot of raw material resources and increase production costs.
[0005] (2) Most of the existing stirring devices do not have a filtration mechanism, and there may be impurities in the raw materials. These impurities enter the reaction vessel, which will affect the performance of the flame retardant and increase the failure rate of the flame retardant. Utility Model Content

This may not only lead to the production of unqualified flame retardants, but also waste a lot of raw material resources and increase production costs.
[0008] To solve the above-mentioned technical problems, the present invention provides the following technical solution:
[0009] A stirring device for producing flame retardants includes a reaction vessel, a drying box at the bottom of the reaction vessel, a stirring assembly inside the reaction vessel, and a filter assembly at the top of the reaction vessel.
[0010] The stirring assembly includes a stirring shaft with several stirring blades, a connecting plate at the top of the stirring shaft, a rotating shaft at the top of the connecting plate, a driving mechanism at the top of the rotating shaft, and a rotation mechanism on the rotating shaft.
[0011] As an improved technical solution, the driving mechanism includes a U-shaped plate, which is located on the top of the reactor. A motor is located on the top of the U-shaped plate, and the output end of the motor is connected to a second rotating shaft.

[0012] As an improved technical solution, the rotating mechanism includes a first gear, which is located at the top of the inner side of the reaction vessel, and a second rotating shaft passes through the first gear. Four third rotating shafts are rotatably connected to the rotating plate, and the four third rotating shafts are evenly distributed. A second gear is provided at the top of each third rotating shaft, and the second gear meshes with the first gear. A third gear is provided at the bottom of each third rotating shaft, and a fourth gear is fixedly connected to the first rotating shaft, and the fourth gear meshes with the third gear.
[0013] As an improved technical solution, there is a gap between the first gear and the rotating plate, and a gap between the connecting plate and the third gear.
[0014] As an improved technical solution, the filter assembly includes a feed channel, two feed channels are symmetrically arranged on the top of the reactor, a filter plate is provided inside the feed channel, the filter plate is provided with a plurality of filter holes, two sets of sliding rods are symmetrically arranged on the filter plate, the filter plate is slidably connected to the sliding rods, two sets of fixing blocks are symmetrically arranged on the inner wall of the feed channel, the bottom end of the sliding rod is fixedly connected to the fixing block, a spring is sleeved on the outer surface of the sliding rod, the spring is located between the filter plate and the fixing block, a circular plate is provided at the top of the sliding rod, and a pushing mechanism is provided below the filter plate.

[0031] like Figure 1 and Figure 5 As shown in the figure, this embodiment provides a stirring device for flame retardant production, including a reaction vessel 1, a drying box 2 at the bottom of the reaction vessel 1, a stirring assembly 3 inside the reaction vessel 1, and a filter assembly 4 at the top of the reaction vessel 1;
[0032] The stirring assembly 3 includes a stirring shaft 31 with several stirring blades 32. A connecting plate 33 is provided at the top of the stirring shaft 31, and a rotating shaft 34 is provided at the top of the connecting plate 33. A driving mechanism is provided at the top of the rotating shaft 34, and a rotation mechanism is provided on the rotating shaft 34. The driving mechanism drives the stirring blades 32 on the stirring shaft 31 to revolve around the sun, and the rotation mechanism drives the stirring blades 32 on the stirring shaft 31 to rotate on their own axis. The revolve and rotation of the stirring blades 32 on the stirring shaft 31 stir and mix the raw materials in the reactor 1, making the raw materials in the reactor 1 more uniformly mixed, thus not affecting the reaction between the raw materials.
[0033] The driving mechanism includes a U-shaped plate 351, which is located on the top of the reactor 1. A motor 352 is located on the top of the U-shaped plate 351. The output end of the motor 352 is connected to a second rotating shaft 353. A rotating plate 354 is located at the bottom of the second rotating shaft 353. The rotating plate 354 is rotatably connected to a first rotating shaft 34. The four first rotating shafts 34 are evenly distributed at the bottom of the rotating plate 354. The second rotating shaft 353 is driven to rotate by the motor 352. The second rotating shaft 353 drives a number of stirring blades 32 on the stirring shaft 31 to rotate through the rotating plate 354. The stirring blades 32 on the stirring shaft 31 are driven to revolve by the motor 352.
[0034] The self-rotating mechanism includes a first gear 361, which is located at the top of the inner side of the reactor 1. A second rotating shaft 353 passes through the first gear 361. Four third rotating shafts 362 are rotatably connected to the rotating plate 354, and the four third rotating shafts 362 are evenly distributed. A second gear 363 is provided at the top of the third rotating shaft 362, and the second gear 363 meshes with the first gear 361. A third gear 364 is provided at the bottom of the third rotating shaft 362. A fourth gear 365 is fixedly connected to the first rotating shaft 34, and the fourth gear 365 meshes with the third gear 361. Gear 364 meshes with the rotating plate 354, which drives the rotating shaft 362 to rotate. The rotating shaft 362 drives the second gear 363 to rotate along the first gear 361. The second gear 363 drives the third gear 364 to rotate through the rotating shaft 362. The third gear 364 drives the connecting plate 33 to rotate through the fourth gear 365. The connecting plate 33 drives the stirring blades 32 on the stirring shaft 31 to rotate. The stirring blades 32 on the stirring shaft 31 further stir and mix the raw materials in the reaction vessel 1 through their rotation.
[0035] There is a gap between the first gear 361 and the rotating plate 354, and a gap between the connecting plate 33 and the third gear 364, to prevent interference between the parts during rotation.
[0036] like Figure 1 , Figure 2 and Figure 5As shown, the filter assembly 4 includes a feed channel 41, with two feed channels 41 symmetrically arranged on the top of the reactor 1. A filter plate 42 is provided inside the feed channel 41, with several filter holes 43 on the filter plate 42. Two sets of sliding rods 44 are symmetrically arranged on the filter plate 42, and the filter plate 42 is slidably connected to the sliding rods 44. Two sets of fixing blocks 45 are symmetrically arranged on the inner wall of the feed channel 41. The bottom end of the sliding rod 44 is fixedly connected to the fixing block 45. A spring 46 is sleeved on the outer surface of the sliding rod 44, and the spring 46 is located between the filter plate 42 and the fixing block 45. A circular plate 47 is provided at the top of the sliding rod 44, and a pushing mechanism is provided below the filter plate 42. The raw material is filtered through the several filter holes 43 on the filter plate 42 to remove impurities, thus not affecting the performance of the flame retardant.
[0037] The actuating mechanism includes a rotating shaft 481, which is rotatably connected to the feed channel 41. A cam 482 is mounted on the rotating shaft 481 and is located below the filter plate 42. A support plate 483 is mounted on the top of the reactor 1 and is rotatably connected to the rotating shaft 481. A first bevel gear 484 is mounted at one end of the rotating shaft 481, and a second bevel gear 485 is mounted on the rotating shaft 353. The second bevel gear 485 meshes with the first bevel gear 484. The rotating shaft 353 drives the first bevel gear 484 to rotate via the second bevel gear 485. The first bevel gear 484 drives the cam 482 to rotate via the rotating shaft 481. The cam 482 intermittently pushes the filter plate 42 upward. Under the combined action of the cam 482 and the spring 46, the filter plate 42 vibrates, preventing the filter holes 43 from becoming clogged.
[0038] During use, the operator adds the raw material into the feed channel 41. The raw material is filtered through several filter holes 43 on the filter plate 42 to remove impurities, thus ensuring the performance of the flame retardant is not affected. Then, the motor 352 is started. The motor 352 drives the second bevel gear 485 to rotate via the second shaft 353. The second bevel gear 485 drives the first bevel gear 484 to rotate via the fourth shaft 481. The first bevel gear 484 drives the cam 482 to rotate. The cam 482 intermittently pushes the filter plate 42 upward along the slide rod 44. The upward movement of the filter plate 42 stretches the spring 46, creating tension. The tension of the spring 46 causes the filter plate 42 to move downward. The combined action of the cam 482 and the spring 46 causes the filter plate 42 to vibrate, preventing clogging of the filter holes 43 and accelerating the filtration efficiency. The filtered raw material then enters... In reactor 1, the rotating plate 354 is driven to rotate by the second rotating shaft 353. The rotating plate 354 drives the stirring blades 32 on the stirring shaft 31 to rotate. The rotating plate 354 drives the third rotating shaft 362 to rotate. The third rotating shaft 362 drives the second gear 363 to rotate along the first gear 361. The second gear 363 drives the third gear 364 to rotate through the third rotating shaft 362. The third gear 364 drives the connecting plate 33 to rotate through the fourth gear 365. The connecting plate 33 drives the stirring blades 32 on the stirring shaft 31 to rotate. The revolution and rotation of the stirring blades 32 on the stirring shaft 31 stir and mix the raw materials in reactor 1, making the raw materials in the reactor more uniformly mixed. This will not affect the reaction between the raw materials, not only avoiding the generation of substandard flame retardants, but also avoiding the waste of a large amount of raw material resources and reducing production costs.

Furthermore, it should be understood that after reading the technical description of this utility model, those skilled in the art can make various alterations, modifications, and / or variations to this utility model, and all such equivalent forms also fall within the scope of protection defined by the appended claims.
