High durability: Coal gangue vitrified microspheres have good resistance to high temperature, humidity, and chemical corrosion environments. 4. Environmentally friendly and sustainable: It utilizes waste coal gangue resources, and the production process does not emit harmful substances, meeting environmental protection requirements. This concrete is mainly used in: 1. Building insulation: Coal gangue vitrified microsphere insulating concrete can be used for exterior wall insulation, roof insulation, and floor insulation of buildings, improving the energy efficiency of buildings. 2. Cold Storage Insulation: Due to its excellent insulation performance, coal gangue vitrified microsphere insulating concrete is suitable for insulation needs in low-temperature environments such as cold storage and cold storage workshops. 3. Insulated Walls: As an insulation material, coal gangue vitrified microsphere insulating concrete can be used to construct wall insulation layers, reducing indoor and outdoor temperature transfer.

[0003] However, most of the relevant technologies describe the mixing method for this coal gangue vitrified microsphere thermal insulation concrete as manual mixing. This method is time-consuming, labor-intensive, inconvenient, and the mixing effect is unstable, which affects the quality of the concrete produced. Summary of the Invention

[0004] To address the technical problems mentioned in the background section, this invention provides a mixing device for thermally insulating concrete made from vitrified microspheres made from coal gangue.

[0024] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0025] Example 1

[0026] Please combine Figures 1 to 5A mixing device for vitrified microsphere insulating concrete made from coal gangue includes a mixing container 1, which has an inlet 2 and an outlet 3. The top of the mixing container 1 is closed, and the bottom has an ellipsoidal structure. The outlet 3 is located at the bottom of the ellipsoidal structure, and a discharge valve is installed on the outside of the outlet 3. A drive shaft 4 is coaxially arranged inside the mixing container 1, and a motor 8 is installed on the top of the mixing container 1. The output shaft of the motor 8 is connected to the top of the drive shaft 4.

[0027] A first disc 5 is concentrically arranged at the bottom of the drive shaft 4. At least one driven shaft 6 parallel to the drive shaft 4 is eccentrically arranged on the disc surface of the first disc 5. A first stirring paddle 7 is arranged at the bottom of the driven shaft 6. The circumferential rotation of the first disc 5 can drive the first stirring paddle 7 to move circumferentially in the mixing container 1, thereby increasing the mixing range of the material in the mixing container 1.

[0028] An actuating mechanism is provided inside the mixing container 1. The actuating mechanism is driven by the rotation of the transmission shaft 4, which can guide the first stirring paddle 7 to rotate itself and improve the mixing effect.

[0029] Specifically, the actuating mechanism includes a first cylinder 9, which is sleeved on the outside of the transmission shaft 4, with a gap between the first cylinder 9 and the transmission shaft 4. The top of the first cylinder 9 is fixed to the inner top wall of the stirring container 1, so the first cylinder 9 is stationary, while the transmission shaft 4 can rotate relative to the first cylinder 9. In this embodiment, the transmission shaft 4 can rotate relative to the first disc 5.

[0030] The third disc 21 is fixedly sleeved on the outer periphery of the first cylinder 9. The top of the driven shaft 6 is provided with a roller 12 that contacts and rubs against the outer periphery of the third disc 21. The circumferential rotation of the driven shaft 6 in the stirring container 1 can drive the roller 12 to move circumferentially around the outer periphery of the third disc 21, so that the roller 12 rotates itself and drives the driven shaft 6 and the first stirring paddle 7 to rotate synchronously.

[0031] Furthermore, a radial groove 13 is provided on the first disc 5, and a second cylinder 10 is slidably engaged in the radial groove 13. The outer wall of the second cylinder 10 is elastically connected to the groove wall of the radial groove 13. The driven shaft 6 passes through the second cylinder 10 and can rotate relative to the second cylinder 10. A cam 11 is provided on the outer periphery of the third disc 21 to engage with the roller 12 through contact friction.

[0032] A telescopic rod is provided between the centrifugal end in the radial groove 13 and the corresponding outer wall of the second cylinder 10. A spring is sleeved on the outside of the telescopic rod. When the spring is in a non-deformed state, the roller 12 touches and rubs against the area of ​​the non-cam 11 on the outer periphery of the third disc 21.

[0033] Therefore, when the roller 12 moves to the area of ​​the cam 11 on the third disc 21, it will force the second cylinder 10 to move centrifugally in the radial groove 13 (compression spring and telescopic rod), and when the roller 12 leaves the cam 11, it will force the second cylinder 10 to move centripetally in the radial groove 13 to the initial position under the action of the spring. As the first disc 5 continues to rotate, the first stirring paddle 7 will reciprocate radially in the stirring container 1, increasing the stirring range and improving the stirring effect.

[0034] A ring 15 is fitted around the outer periphery of the driven shaft 6 and located below the second cylinder 10. At least one third cylinder 16 is arranged circumferentially on the ring 15 to increase the stirring range and improve the stirring effect and efficiency.

[0035] Multiple radially extending second stirring paddles 17 are arranged on the outer periphery of the third cylinder 16 along its axial direction to increase the stirring range and improve the stirring effect and efficiency.

[0036] The third cylinder 16 forms an inclined rod-shaped structure from its bottom to its top and along the centrifugal direction, increasing the stirring range.

[0037] The bottom of the second cylinder 10 is coaxially provided with a second disc 14 parallel to the first disc 5. A connecting rod 18 is rotatably connected to the outer periphery of the bottom of the second disc 14. The end of the connecting rod 18 away from the second disc 14 is slidably locked inside the end of the third cylinder 16 near the second disc 14. The other end of the third cylinder 16 is rotatably connected to the outer wall of the ring 15. The ring 15 can move relative to the driven shaft 6 in the axial direction.

[0038] In summary, when the driven shaft 6 drives the first stirring paddle 7 to rotate and stir, it can also drive the ring body 15, the third cylinder 16 and the second stirring paddle 17 to rotate synchronously, thereby increasing the stirring range and improving the stirring effect and efficiency. Furthermore, by adjusting the speed of the output shaft of the motor 8, the magnitude of the centrifugal force on the third cylinder 16 can be adjusted, thereby adjusting the stirring height and tilt angle of the second stirring paddle 17 in the axial direction of the driven shaft 6, further improving the stirring effect and efficiency.

[0039] Example 2

[0040] This embodiment is an improvement on embodiment 1. A continuous, closed-loop limiting groove 20 is provided on the circumferential side wall of the driven shaft 6, which unfolds into a figure-eight shape. A limiting block 19 is provided on the inner circumferential side of the ring body 15, which slides and engages with the limiting groove 20.

[0041] In other words, the driven shaft 6 can not only drive the first stirring paddle 7 and the second stirring paddle 17 to move circumferentially, rotate itself, and reciprocate radially in the mixing container 1, but also, even when the speed of the motor 8 is constant (without needing to adjust the speed of the motor 8), the unidirectional rotation of the driven shaft 6 itself can force the groove wall of the continuous, closed-loop, and figure-eight shaped limiting groove 20 to continuously rub and squeeze the limiting block 19 of the ring body 15, so that the ring body 15 reciprocates in the axial direction of the driven shaft 6, thereby continuously changing the position of the second stirring paddle 17 in the axial direction of the driven shaft 6 and the tilt angle of the second stirring paddle 17, thereby further increasing the mixing range and improving the mixing effect and efficiency.

[0042] The above embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention shall fall within the scope of protection claimed by the present invention.
