Description

Technical Field

[0001] This utility model relates to the field of flame retardant technology, specifically to a mixer for flame retardants. Background Technology

[0002] Flame retardants are composed of a combination of various materials. In order to improve the flame retardant effect, the various materials need to be mixed evenly during the production process.

[0003] Chinese patent document CN218221918U discloses a flame retardant production mixing machine, including a barrel body. A mixing tank is fixedly connected to the inner wall of the barrel body. A feed inlet is opened on the upper surface of the barrel body. A guide pipe is fixedly connected to the bottom of the feed inlet and extends into the interior of the mixing tank. A first motor is fixedly connected to the middle of the upper surface of the barrel body. The output end of the first motor extends into the interior of the mixing tank and is fixedly connected to a first rotating rod. A dispersing disc is fixedly connected to the outer wall of the first rotating rod. A second rotating rod is fixedly connected to the middle of the lower surface of the bottommost dispersing disc. A stirring rod is fixedly connected to the outer wall of the second rotating rod.

[0004] However, in the above scheme, the inner bottom of the mixing barrel is concave downwards, and there is a gap between the stirring rod and the inner bottom of the mixing barrel. When the raw materials are dispersed by the dispersing disc, they will move along the inner wall of the mixing barrel towards the inner bottom, resulting in incomplete mixing of the raw materials in the mixing barrel and poor uniformity of the raw materials.

[0029] Example 1

[0030] like Figure 1-4 As shown, the present invention proposes a mixer for flame retardants, which includes a support frame 1, a valve 7, a mixing cylinder 8, a stirrer, and a drive assembly.

[0031] Both ends of the mixing cylinder 8 are equipped with sleeves 10. The sleeves 10 are rotatably mounted on the top of the support frame 1 via bearings (not shown in the figure). The bottom of the mixing cylinder 8 is provided with a collection shell for moving the flame retardant raw material inside the mixing cylinder 8 from the bottom to the top of the inner side of the mixing cylinder 8 during the mixing state. The valve 7 is installed at the bottom of the collection shell.

[0032] The agitator is rotatably disposed inside the mixing cylinder 8 along the axial direction of the mixing cylinder 8, and both ends are rotatably installed in the sleeve 10, with one end extending to the end of the sleeve 10.

[0033] There are two drive components, which are respectively installed on both sides of the support frame 1 and are connected to the mixing cylinder 8 and the agitator respectively.

[0034] In an optional embodiment, the top of the mixing cylinder 8 is provided with a feed inlet 9, which is symmetrically arranged with the collection shell along the central axis of the mixing cylinder 8, for adding raw materials to the inside of the collection shell. The feed inlet 9 is either a flange or a clamp joint.

[0035] In this embodiment, the flame retardant raw material is conveyed to the inside of the mixing cylinder 8 through the feed inlet 9 connected to the conveying device, causing the raw material to move towards the inside of the collection shell. By sealing the feed inlet 9 and simultaneously activating the drive assembly, one drive assembly drives the mixing cylinder 8 to rotate at the top of the support frame 1 through the sleeve 10. This causes the mixing cylinder 8 to move the collection shell around the circumference of the mixing cylinder 8, causing the raw material inside the collection shell to move towards the top of the mixing cylinder 8 and be scattered, thus mixing the raw material. At the same time, another drive assembly drives the agitator to rotate, causing the agitator to rotate inside the mixing cylinder 8. This allows the agitator to contact the scattered raw material and exert force on some of the raw material, changing the falling position of some of the raw material, improving the mixing uniformity and increasing the mixing efficiency.

[0036] Example 2

[0037] like Figure 1-3 As shown, the present invention proposes a mixer for flame retardants. Compared with the first embodiment, the difference in this embodiment is that the collecting shell includes a connecting shell 5 and a flow guiding shell 6.

[0038] The connecting shell 5 is installed at the bottom of the mixing cylinder 8 and communicates with the mixing cylinder 8;

[0039] The flow guide shell 6 is installed at the bottom of the connecting shell 5 and communicates with the connecting shell 5, and the bottom end is connected to the valve 7.

[0040] In an optional embodiment, the inner diameter of the flow guide shell 6 gradually decreases from the connecting shell 5 toward the support frame 1 along the height direction of the connecting shell 5.

[0041] In this embodiment, a connecting shell 5 is installed at the bottom of the mixing cylinder 8 and communicates with it. A guide shell 6 is installed at the bottom of the connecting shell 5 and communicates with it. This creates a cavity on the inner side of the connecting shell 5 and the guide shell 6, increasing the space inside the mixing cylinder 8. As the mixing cylinder 8 rotates, the inner walls of the connecting shell 5 and the guide shell 6 cause the raw material to rotate with the mixing cylinder 8, allowing the raw material inside the mixing cylinder 8 to be scattered. At the same time, the shape of the guide shell 6 guides the mixed raw material to the valve 7, making the discharge of the raw material more convenient.

[0042] Example 3

[0043] like Figure 3 As shown, the present invention proposes a mixer for flame retardants. The difference between this embodiment and the first embodiment is that the mixer includes a rotating shaft 4 and a stirring blade 12.

[0044] The rotating shaft 4 is located inside the mixing cylinder 8 and is arranged coaxially with the mixing cylinder 8. Both ends of the rotating shaft 4 are rotatably mounted inside the sleeve 10 through bearings (not shown in the figure), and one end extends to the end of the sleeve 10 and is connected to the drive assembly for transmission.

[0045] The number of stirring blades 12 is multiple. Multiple stirring blades 12 are located inside the mixing cylinder 8 and are equidistantly sleeved on the outside of the rotating shaft 4. The multiple stirring blades 12 are arranged symmetrically with respect to the center of the mixing cylinder 8.

[0046] In this embodiment, the drive assembly drives the rotating shaft 4 to rotate, which in turn drives the stirring blades 12 to rotate inside the mixing cylinder 8. This causes the stirring blades 12 to strike the scattered raw materials. By symmetrically arranging multiple stirring blades 12, some of the raw materials fall to both ends of the inner side of the mixing cylinder 8, thus changing the falling position of some raw materials and improving the mixing uniformity of the raw materials.

[0047] Example 4

[0048] like Figure 3-4 As shown, the present invention proposes a mixer for flame retardants. Compared with embodiment three, the difference in this embodiment is that multiple sleeves 11 are provided between every two stirring blades 12, and every two sleeves 11 form a group, and a connecting rod 13 is inserted between every two sleeves 11.

[0049] In this embodiment, by providing a sleeve 11 on the side of the stirring blade 12, a connecting rod 13 is installed between every two stirring blades 12, so that the connecting rod 13 strikes the scattered raw materials when the stirring blade 12 rotates, thereby increasing the striking range of the stirring blade 12 and further improving the uniformity of the raw material mixing.

[0050] Example 5

[0051] like Figure 1-2 As shown, the present invention proposes a mixer for flame retardants. Compared with the first embodiment, the difference in this embodiment is that the driving component includes a motor 2 and a transmission component 3.

[0052] The motor 2 is mounted on the side of the support frame 1, and its output shaft is arranged coaxially with the mixing cylinder 8;

[0053] The transmission component 3 is mounted on the output shaft of the motor 2. The transmission component 3 is one of the mechanical transmission structures such as chain drive, belt drive or gear drive.

[0054] In this embodiment, two motors 2 drive the transmission components 3 to operate, so that the two transmission components 3 drive the mixing cylinder 8 and the rotating shaft 4 respectively, so that the difference in rotational speed between the mixing cylinder 8 and the rotating shaft 4 can be adjusted, thereby improving the mixing effect of the raw materials.

[0055] In summary, in this utility model, the flame retardant raw material is conveyed into the mixing cylinder 8 via a conveying device connected to the inlet 9. A connecting shell 5 is installed at the bottom of the mixing cylinder 8 and communicates with it. A guide shell 6 is installed at the bottom of the connecting shell 5 and communicates with it, creating a cavity on the inner side of the connecting shell 5 and the guide shell 6 that increases the internal space of the mixing cylinder 8. The raw material is placed into this cavity. The inlet 9 is then blocked, and the motor 2 is started, causing the motor 2 to drive the transmission component 3. The transmission component 3, through the sleeve 10, drives the mixing cylinder 8 to rotate at the top of the support frame 1. 8 drives the connecting shell 5 and the guide shell 6 to move circumferentially along the mixing cylinder 8, causing the connecting shell 5 and the guide shell 6 to move the raw material to the inner top of the mixing cylinder 8 and to perform the throwing operation. By starting another motor 2, the motor 2 drives the rotating shaft 4 to rotate through another transmission component 3, causing multiple stirring blades 12 inside the mixing cylinder 8 to rotate. The stirring blades 12 contact and strike the thrown raw material, and through the shape of the stirring blades 12, some of the raw material falls to both ends of the inner side of the mixing cylinder 8, changing the falling position of the raw material, improving the mixing uniformity of the raw material, and increasing the mixing efficiency.

[0056] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
