Specific implementation mode

[0027] Next, in combination with the embodiments, the technical solutions of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work belong to the scope of protection of the present invention.

[0028] Refer to Figures 1-5 , the present invention provides a technical solution:

[0029] Embodiment:

[0030] As Figures 1-5 shown, a stirring device for a fire door core material includes a tank body 1 and a stirring shaft 2 arranged in the tank body 1. The stirring shaft 2 is driven by a motor. The tank body includes a straight cylinder section 3 and a conical cylinder section 4;

[0031] A stirring assembly is arranged on the stirring shaft 2. The stirring assembly is used to circulate the raw materials between the bottom of the straight cylinder section 3 and the conical cylinder section 4 and complete stirring in the conical cylinder section 4.

[0032] As Figures 1-3 shown, the stirring assembly includes a first stirring blade 5, a second stirring blade 6 and a (vertically open at both ends) conical return baffle 7. A plurality of first stirring blades 5 are arranged. The first end of the first stirring blade 5 is connected to the stirring shaft 2, and the second end of the stirring blade is arranged downward towards the conical cylinder section 4;

[0033] The taper of the return baffle 7 is the same as that of the conical cylinder section 4 (and the large-diameter end of the return baffle 7 is arranged upward), and the return baffle 7 is coaxially arranged in the conical cylinder section. A raw material return gap 8 is provided between the return baffle 7 and the inner wall of the conical cylinder section 4;

[0034] The first end of the second stirring blade 6 is connected to the stirring shaft 2, the second end of the second stirring blade 6 is freely arranged, and the second stirring blade 6 is arranged parallel to the inner wall of the conical cylinder section 4. The second end of the second stirring blade 6 extends into the raw material return gap 8.

[0035] The second stirring blade 6 is of an L-shaped structure.

[0036] 1. Figure 2 The arrow direction in the figure indicates the raw material circulation direction; 2. The stirring shaft 2 is connected to the output shaft of the motor through a coupling; and to reduce the weight of the stirring shaft 2, the stirring shaft 2 is hollow. 3. To ensure the coaxiality of the stirring shaft 2 and the tank body 1, transverse ribs can be provided at the discharge port of the tank body 1, and the bottom of the stirring shaft 2 is connected to the transverse ribs through a bearing seat and bearings. 4. The first stirring blade 5 is located between the stirring shaft 2 and the inner side of the rising baffle 7. 5. The rising baffle 7 is provided with an opening groove for the first stirring blade 5 to pass through to facilitate the installation of the stirring blade.

[0037] Working principle: After the raw materials enter the tank body 1, the motor is started; the motor drives the stirring shaft 2 to rotate.

[0038] When the stirring shaft 2 rotates, the first stirring blade 5 cooperates with the inner side of the rising baffle 7 to press down the powder material (referring to the raw material: specifically powdered cement), and during this process, the first stirring blade 5 stirs the powder material at the same time. When the divided material is pressed to the lower end of the rising baffle 7, and as the powder material is continuously pressed down, the powder material at the lower end of the rising baffle 7 is extruded to re-enter the conical section 4 through the raw material rising gap 8 (the powder material inside the rising baffle 7 is under pressure, while there is no pressure acting between the raw material rising gaps 8. Therefore, when the powder material is pressed to the bottom end of the rising baffle 7, it rises and flows back through the raw material rising gap 8 under the extrusion of the first stirring blade 5). During this process, the second stirring blade 6 drives the powder material to move to ensure that the powder material is evenly distributed in the rising gap.

[0039] After the powder material enters the conical section 4, it is stirred and pressed down by the first stirring blade 5 again, and so on in a cycle to achieve the blending and mixing of the upper and lower layers of powder materials.

[0040] The utility model can ensure the vertical flow of the powder material during the stirring process by setting the stirring assembly, thereby ensuring the full mixing of the powder material and solving the problem of uneven mixing of the powder material due to only horizontal stirring.

[0041] Further, as Figure 2 and Figure 4 shown, the inner wall of the rising baffle 7 is provided with a first rib plate, the inner wall of the straight cylinder section 3 is provided with a second rib plate, and the rising baffle 7 is connected to the straight cylinder section 3 through the first rib plate, the second rib plate, and the connecting rod 9.

[0042] After the rising baffle 7 is assembled with the first rib plate and the connecting rod 9 in this way, only by connecting the upper end of the connecting rod 9 to the second rib plate outside the tank body 1 can the installation of the rising baffle 7 be completed. The rising baffle 7 is convenient to install and has strong operability.

[0043] Further, as Figures 3-5As shown, a valve plate 10 that can be opened and closed is provided at the bottom of the tank body 1, and the valve plate 10 is used to seal the discharge port of the tank body 1.

[0044] The valve plate 10 is rotatably connected to the bottom of the tank body 1 through a rotating shaft 11 (one side of the valve plate 10 is connected to the rotating shaft 11), one end of the rotating shaft 11 is connected to the first end of a driving plate 12, and the second end of the driving plate 12 is connected to the piston rod of a cylinder 13;

[0045] The cylinder 13 is connected to the outer wall of the tank body 1 through a connecting frame 14. A connecting plate is provided at the discharge port of the tank body 1, and a rotating seat (which can be, but is not limited to, a bearing seat) is provided on the connecting plate, and the rotating shaft 11 is rotatably connected to the rotating seat.

[0046] With such a setting, the valve plate 10 is opened outward, thereby avoiding the influence of the installation of the internal stirring shaft 2 on the opening and closing of the valve plate 10. When the valve plate 10 needs to be opened, the cylinder 13 is started to retract the piston rod. In this process, the piston rod drives the rotating shaft 11 to rotate through the connecting plate, thereby opening the valve plate 10. Among them, to ensure the stability of the opening and closing of the valve plate 10, both ends of the rotating shaft 11 are respectively connected to the cylinder 13, and the two cylinders 13 act synchronously.

[0047] Further, as Figure 3 and Figure 5 shown, a cross-shaped support frame 15 is provided at the top inside the tank body 1, and the motor is supported by the support frame 15.

[0048] A sealing plate is provided on the top surface of the support frame 15, and a feed port is provided on the sealing plate.

[0049] Arc-shaped cover plates 16 are respectively connected to both sides of the support frame 15 through hinges. The cover plates 16 are used to seal the top of the tank body 1, and handles are provided on the cover plates 16.

[0050] The provided cover plates are convenient to open for cleaning or overhauling the inside of the tank body.

[0051] The above is only the preferred embodiment of the present invention. It should be understood that the present invention is not limited to the form disclosed herein, should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be changed within the scope of the concept described herein through the above teachings or the technology or knowledge in related fields. And the changes and modifications made by those skilled in the art that do not depart from the spirit and scope of the present invention should all be within the protection scope of the appended claims of the present invention.
