Description

Technical Field

[0001] This utility model relates to the field of flame retardant production technology, specifically to a flame retardant production foaming device. Background Technology

[0002] Flame retardant foaming apparatus is a very common instrument in flame retardant experiments. Its working principle is to prepare a flame retardant foaming fluid by fully mixing water as the liquid phase and gas as the gas phase.

[0003] The existing foaming devices for flame retardants do not achieve ideal foaming effects. Gas cannot be injected evenly into the flame retardant liquid, and the resulting foamed fluid is not rich or fine enough, which affects the performance of the flame retardant.

[0004] To address the aforementioned issues, there is an urgent need for innovative designs based on existing flame retardant foaming devices. Utility Model Content

[0005] The purpose of this invention is to provide a foaming device for producing flame retardants, in order to solve the problems mentioned in the background art, such as the unsatisfactory foaming effect of existing flame retardant foaming devices, the inability to uniformly inject gas into the flame retardant liquid, and the insufficient richness and fineness of the foamed fluid obtained, which affects the performance of the flame retardant.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a foaming device for producing flame retardants, comprising a foaming tank, a servo motor fixed to the surface of the foaming tank, a stirring rod fixed to the output end of the servo motor, a first through hole on the surface of the stirring rod, a stirring blade disposed outside the first through hole, a gas supply hole on the surface of the stirring blade, a groove rail on the surface of the stirring rod, a cover disposed outside the stirring rod, the edge of the cover located within the groove rail, a sealing ring disposed at one end of the cover located within the groove rail, a second through hole on one section of the stirring rod located within the cover, and a metal gas supply pipe fixed to the surface of the cover.

[0007] Preferably, the stirring blades are hollow and are distributed at equal angles on the surface of the stirring rod.

[0008] Preferably, the stirring blade is viewed from above as a "Y"-shaped structure, with air delivery holes evenly distributed in the "Y"-shaped portion.

[0009] Preferably, the cover is rotatably connected to the stirring rod via a grooved rail.

[0010] Preferably, the end of the sealing ring away from the cover is attached to the inner wall of the groove rail.

[0011] Preferably, the stirring rod has a hollow structure, and the second through holes are distributed at equal angles on the stirring rod.

[0012] Preferably, the end of the metal gas pipe furthest from the cover is fixedly connected to the foaming tank through it.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: In this flame retardant production foaming device, after the flame retardant liquid is injected into the foaming tank, the servo motor drives the stirring rod and stirring blade to stir it. During this process, the external gas supply device injects gas through the metal gas supply pipe. The gas will be injected into the hollow stirring rod through the second through hole, and then into the hollow stirring blade through the first through hole. Finally, it is injected into the flame retardant liquid through the gas supply hole on the stirring blade, which facilitates the uniform foaming of the flame retardant liquid during the stirring process.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-5This utility model provides a technical solution: a foaming device for producing flame retardants, including a foaming tank 1, a servo motor 2 fixed on the surface of the foaming tank 1, a stirring rod 3 fixed on the output end of the servo motor 2, a first through hole 4 opened on the surface of the stirring rod 3, a stirring blade 5 arranged on the outer side of the first through hole 4, a gas supply hole 6 opened on the surface of the stirring blade 5, a groove rail 7 also opened on the surface of the stirring rod 3, a cover 8 arranged on the outer side of the stirring rod 3, the edge of the cover 8 located in the groove rail 7, a sealing ring 9 arranged at one end of the cover 8 located in the groove rail 7, a second through hole 10 opened on the section of the stirring rod 3 located in the cover 8, and a metal gas supply pipe 11 fixed on the surface of the cover 8.

[0022] The stirring blade 5 has a hollow structure and is distributed at equal angles on the surface of the stirring rod 3. The stirring rod 3 has a hollow structure and the second through hole 10 is distributed at equal angles on the stirring rod 3 to facilitate the injection of gas into the stirring rod 3. The gas is injected into the hollow stirring blade 5 through the first through hole 4.

[0023] The stirring blade 5 is viewed from above as a "Y"-shaped structure. The "Y"-shaped part has gas inlets 6 evenly distributed. The gas inside the stirring blade 5 can be evenly injected into the flame retardant liquid in the foaming tank 1 through the gas inlets 6.

[0024] The cover 8 is rotatably connected to the stirring rod 3 via the groove 7, which facilitates the rotation of the cover 8 on the stirring rod 3 via the groove 7.

[0025] The end of the sealing ring 9 away from the cover 8 is attached to the inner wall of the groove rail 7, which improves the tightness of the fit between the cover 8 and the groove rail 7 and prevents leakage.

[0026] The end of the metal gas supply pipe 11 away from the cover 8 is fixedly connected to the foaming tank 1, which improves the stability of the installation of the metal gas supply pipe 11. The stably installed metal gas supply pipe 11 can stably support the cover 8 and prevent the cover 8 from rotating synchronously with the stirring rod 3.

[0027] Working principle: When using this foaming device, such as Figures 1-5 As shown, the flame retardant liquid is first poured into the foaming tank 1, and then the servo motor 2 is started. At this time, the servo motor 2 drives the stirring rod 3 to rotate, and the stirring rod 3 drives the stirring blade 5 to stir the flame retardant liquid in the foaming tank 1. While the stirring blade 5 is stirring, the external gas supply device supplies gas to the stirring rod 3 through the metal gas pipe 11 and the cover 8. At this time, the gas in the cover 8 passes through the second through hole 10 and is injected into the hollow stirring rod 3. Then, the gas in the stirring rod 3 passes through the first through hole 4 and is injected into the hollow stirring blade 5. Then, it is evenly dispersed into the flame retardant liquid through the gas supply hole 6 on the stirring blade 5, which facilitates stirring and uniform foaming.

[0028] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
