[0026] See also Figure 1-6 , the utility model provides a technical solution:

[0027] A fireproof sealant preparation and mixing device includes a control device 2 and a stirring blade 3. A stirring container 1 is provided on one side of the control device 2. The stirring blade 3 is rotatably connected to the inner side of the stirring container 1. The stirring container 1 includes a stirring box 11. A sealing groove 12 is provided on the upper end of the stirring box 11. A fixed shaft 13 is fixedly connected to one side of the stirring box 11. The outer side of the fixed shaft 13 is rotatably connected to a sealing device 4. The sealing device 4 includes a sealing plate 41. The inner side of the sealing plate 41 is fixedly connected to a mounting ring 42 by bolts. The inner side of the mounting ring 42 is fixedly connected to There is a limit rod 44, and a guide rod 45 is slidably connected to the inner side of the limit rod 44. One end of the guide rod 45 is fixedly connected to a limit block 46. The outer side of the guide rod 45 is fixedly connected to a pressure spring 47. A sliding groove 48 is provided at the upper end of the mounting ring 42, and a guide device 43 is fixedly connected to the upper end of the guide rod 45; the guide device 43 includes a sealing cover 431, a guide block 432 is fixedly connected to the center position of the lower end of the sealing cover 431, and a limit ring 433 is fixedly connected to the lower end of the sealing cover 431. An air outlet 434 is provided on one side of the limit ring 433.

[0028] As a further implementation of the above technical solution: a plurality of limit rods 44, guide rods 45, limit blocks 46 and pressure springs 47 are provided. The limit rods 44, guide rods 45, limit blocks 46 and pressure springs 47 are distributed in a circular array inside the mounting ring 42. The other end of the pressure spring 47 is fixedly connected to the upper end of the limit rod 44. The guide rod 45 can only slide up and down inside the limit rod 44, thereby preventing deviation or shaking when subjected to pressure, ensuring that the guide device 43 is more stable during the up and down movement.

[0029] As a further implementation of the above technical solution: by setting the guide block 432 in a semicircular shape, the chute 48 is annular, the limit ring 433 is slidably connected to the inner side of the chute 48, the bottom of the sealing cover 431 is U-shaped, and the guide block 432 is semicircular, when the gas in the mixing box 11 enters the guide device 43, the guide block 432 can guide and diffuse the gas evenly to the surroundings, and can change the flow direction of the gas, making it flow more smoothly, reducing the impact on the sealing device 4;

[0030] As a further implementation scheme of the above technical solution: a plurality of air outlet holes 434 are provided, and the cross-section of the air outlet holes 434 is arranged in a trapezoidal shape. The air outlet holes 434 are evenly and equidistantly distributed inside the limiting ring 433. The outer sides of the air outlet holes 434 are in close contact with the inner sides of the chute 48. The air outlet holes 434 can discharge the gas in time, thereby maintaining the pressure in the stirring container 1 stable. At the same time, when the pressure in the stirring container 1 is higher than the external ambient pressure, the air outlet holes 434 can discharge the gas outward, reduce the internal pressure, and achieve internal and external pressure balance.

[0031] As a further implementation of the above technical solution: by setting the limit rod 44 and the pressure spring 47 perpendicular to one side of the limit rod 44 and the limit block 46, the limit rod 44 and the limit block 46 are parallel to each other, and the center point of one end of the limit rod 44 and the center point of the limit block 46 are located on the same vertical line. The setting of the limit block 46 can prevent the guide rod 45 from slipping off the limit rod 44, thereby ensuring the structural integrity of the entire sealing device 4. At the same time, it also limits the maximum upward movement distance of the guide device 43, thereby preventing damage to the sealing device 4 or affecting its sealing performance due to excessive displacement;

[0032] As a further implementation of the above technical solution: a sealing plate 41 is fixedly connected to the upper end of the mixing box 11 by bolts, and the sealing groove 12 and the sealing ring 49 correspond to each other. The sealing groove 12 and the sealing ring 49 are both square in shape, and the sealing ring 49 is installed inside the sealing groove 12. During the mixing process, the rotation of the stirring blade 3 will generate a certain amount of vibration and impact force. The sealing plate 41 can effectively disperse these forces, reduce the impact on the structure of the mixing box 11, and prevent the mixing box 11 from deformation or damage.

[0033] As a further implementation scheme of the above technical solution: a mounting ring 42 is set to pass through the sealing plate 41, the mounting ring 42 is set at the center of the sealing plate 41, the center point of the mounting ring 42 and the guide device 43 are located on the same vertical line, and the guide device 43 is set above the sealing plate 41. Such an arrangement can make the overall structure more complete.

[0034] Working process: First, fix the sealing plate 41 to the upper end of the mixing box 11 by bolts, so that the sealing groove 12 and the sealing ring 49 correspond to each other to ensure the sealing effect. The control device 2 is energized through the external wire, and then the stirring blade 3 is started by the control device 2 to start stirring and mixing the fireproof sealant raw materials in the mixing box 11. During the stirring process, gas or pressure changes may be generated in the mixing box 11. When the pressure in the mixing box 11 increases, the gas pushes the sealing cover 431 of the guide device 43 upward. After the sealing cover 431 is subjected to upward pressure, it slides upward along the slide groove 48 through the limit ring 433, and at the same time drives the guide rod 45 to slide upward on the inner side of the limit rod 44, compressing the pressure spring Spring 47, as the sealing cover 431 moves upward, a gap is generated between the sealing cover 431 and the mounting ring 42, and the gas in the mixing box 11 enters the guide device 43 through the gap. The gas in the guide device 43 is guided by the guide block 432 and diffuses to the surroundings. Then, the gas is discharged through the air outlet holes 434 evenly and equidistantly distributed on the limit ring 433. When the pressure in the mixing box 11 decreases, the elastic force of the pressure spring 47 pushes the guide rod 45 and the sealing cover 431 to move downward and return to the initial sealing state. When the fireproof sealant is stirred and mixed, the stirring blade 3 is stopped by the control device 2, the sealing device 4 can be opened, and the stirred fireproof sealant can be taken out for subsequent processing.

[0035] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
