[0002] A flame retardant is a functional additive that imparts flame retardancy to flammable polymers. It is mainly designed for the flame retardancy of polymer materials. There are various types of flame retardants. According to the usage method, they are divided into additive flame retardants and reactive flame retardants. Additive flame retardants are added to polymers by mechanical mixing methods to make the polymers flame retardant. Currently, the main additive flame retardants are organic flame retardants and inorganic flame retardants. Halogen-based flame retardants (organic chlorides and organic bromides) and non-halogen ones. Organic ones are represented by some flame retardants such as bromine-based, phosphorus-nitrogen-based, nitrogen-based, red phosphorus and its compounds.

[0031] As Figures 1 to 5 collectively shown, the present utility model provides a discharging device for a feeder of a flame retardant, including a feeder body 1. A discharging main body 2 is arranged at the discharging port of the feeder body 1. The discharging main body 2 includes a material receiving pipe 21 and a driving source 26. The material receiving pipe 21 is installed at the discharging port of the feeder body 1. A collecting bin 22 is rotatably installed at the discharging port of the material receiving pipe 21. A discharging pipe 23 is installed at the discharging end of the collecting bin 22;

[0032] A gear 210 is installed on the outer wall surface of the collecting bin 22. A rack 28 meshing with the gear 210 is arranged at the driving end of the driving source 26.

[0033] A feeding device discharging device for preparing a flame retardant according to an embodiment of the present utility model. When discharging, the driving motor 264 drives the rotating plate 262 to rotate. Under the linkage action of the two vertical shafts, the push-pull bar 263 and the U-shaped seat 265, when the rotating plate 262 rotates one circle, it can first pull the rack 28 to move to the left, and then the rack 28 will move to the right to reset. Under the meshing transmission action of the rack 28 and the gear 210, the aggregate bin 22 and the discharge pipe 23 installed at its outlet end rotate. Then, one rotation of the rotating plate 262 will cause the discharge pipe 23 to rotate clockwise first and then rotate counterclockwise to reset, that is, the discharge pipe 23 is in a reciprocating swing state. When the material passes through the discharge port of the discharge pipe 23, the swing of the discharge pipe 23 will change the position of the discharge port of the discharge pipe 23, thus expanding the falling range of the material of the discharging device, making the range where the material falls into the bucket wider, and being more conducive to quickly stirring the material evenly subsequently.

[0034] As Figure 2 shown, in this embodiment, the discharging main body 2 further includes a servo motor 25 installed on the top of the feeder body 1. The driving end of the servo motor 25 extends into the inside of the receiving pipe 21. A spiral blade 24 is welded on the outer wall surface of the driving end of the receiving pipe 21 and located inside the receiving pipe 21. The material inside the feeder body 1 naturally falls into the inside of the receiving pipe 21. The servo motor 25 drives the spiral blade 24 to rotate, so that the material continuously enters the inside of the receiving pipe 21 and enters the inside of the discharge pipe 23 after being guided by the aggregate bin 22. When the servo motor 25 stops, the feeder body 1 stops discharging, and the control of loading and unloading is very convenient.

[0035] As Figure 1 With Figure 3 shown together, in this embodiment, the driving source 26 includes a bottom box 261. A driving motor 264 is installed at the center of the top of the bottom box 261. The driving end of the driving motor 264 is fixedly connected to a rotating plate 262. A U-shaped seat 265 is welded on the side of the rack 28 close to the bottom box 261. Vertical shafts are installed on the outer side of the upper surface of the rotating plate 262 and inside the U-shaped seat 265, and a push-pull bar 263 is rotatably installed between the two vertical shafts. When discharging, the driving motor 264 drives the rotating plate 262 to rotate. Under the linkage action of the two vertical shafts, the push-pull bar 263 and the U-shaped seat 265, when the rotating plate 262 rotates one circle, it can first pull the rack 28 to move to the left, and then the rack 28 will move to the right to reset. Under the meshing transmission action of the rack 28 and the gear 210, the aggregate bin 22 and the discharge pipe 23 installed at its outlet end rotate. Then, one rotation of the rotating plate 262 will cause the discharge pipe 23 to rotate clockwise first and then rotate counterclockwise to reset, that is, the discharge pipe 23 is in a reciprocating swing state.

[0036] As Figures 2 to 3As shown together, in this embodiment, a welding plate 29 is welded to the outer wall surface of the material receiving pipe 21, and the rack 28 is slidably limited at the bottom of the welding plate 29.

[0037] As Figures 2 to 4 As shown together, in this embodiment, a dovetail slide base 211 is welded to the outside of the bottom of the welding plate 29. A dovetail slider 212 is installed in the middle of the upper surface of the rack 28, and the dovetail slider 212 is slidably limited in the dovetail slide cavity of the dovetail slide base 211, which plays a role in limiting the rack 28 to ensure the stability of the meshing transmission between the rack 28 and the gear 210.

[0038] As Figures 2 to 3 As shown together, in this embodiment, an air outlet diffusion structure 27 is arranged inside the bottom box 261, and the air outlet end of the air outlet diffusion structure 27 is sleeved on the vertical pipe end of the discharge pipe 23. At the same time, the air outlet end of the air outlet diffusion structure 27 is communicated with the inside of the discharge pipe 23.

[0039] During the discharging process, the fan 271 pumps air and conveys the air to the inside of the collar bin 274 through the metal hose 272 and the air inlet connecting pipe 273. Finally, it enters the inside of the discharge pipe 23 through the communication holes 275. When the air enters the inside of the discharge pipe 23, it will blow the material passing through the inside of the discharge pipe 23, accelerating the discharge of the material from the inside of the discharge pipe 23. Moreover, it adds a boost to the discharged material, further dispersing the material into the inside of the bucket.

[0040] As Figures 2 to 3 、 Figure 5 As shown together, in this embodiment, the air outlet diffusion structure 27 includes a fan 271 installed inside the bottom box 261, and the air outlet end of the fan 271 is located outside the bottom box 261. An air inlet hole is provided on the bottom box 261. A collar bin 274 is welded to the outer wall surface of the vertical pipe end of the discharge pipe 23. An air inlet connecting pipe 273 is welded at the air inlet of the collar bin 274. A metal hose 272 is installed between the outlet end of the fan 271 and the inlet end of the air inlet connecting pipe 273. Three communication holes 275 are penetrated and opened at the vertical pipe end of the discharge pipe 23, and the collar bin 274 is communicated with the inside of the discharge pipe 23 through the communication holes 275. The setting of the metal hose 272 will be stretched when subjected to tension to ensure normal ventilation operation.

[0041] As Figure 5 As shown, in this embodiment, the communication holes 275 are arranged in an inclined state, and their inclined openings face downward. The inclined openings facing downward limit the movement direction of the air flow. When the air enters the inside of the discharge pipe 23, its flow direction is obliquely downward, which is more conducive to accelerating the discharge of the material from the inside of the discharge pipe 23.

[0042] It should be understood that the use of these embodiments is only for illustrating the present utility model rather than intending to limit the protection scope of the present utility model. In addition, it should also be understood that after reading the technical content of the present utility model, those skilled in the art can make various changes, modifications and / or variations to the present utility model, and all these equivalent forms also fall within the protection scope defined by the appended claims of this application.
