[0021] The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments. It should be noted that the embodiments and features in the embodiments of the present invention can be combined with each other without conflict.

[0022] Embodiment: This embodiment aims to provide a slurry preparation device for grouting in coal mine goaf areas. Its main function is to reduce the failure rate of traditional slurry preparation devices after long-term use. At the same time, by reducing the number of mechanical parts, it can also simplify the subsequent maintenance process, reduce the labor intensity of the staff, and speed up the slurry preparation progress.

[0023] Reference Figure 1 , Figure 2 and Figure 3 , comprising: a bottom plate 1, a pair of vertical plates 2, a spherical tank 3, an annular gear track 6 and a material conveying channel 9. Vertical plates 2 are provided on both sides of the upper surface of the bottom plate 1. The two vertical plates 2 have a convex crossbar 201 for hanging the spherical tank 3 on one side corresponding to each other. The spherical tank 3 is rotatably arranged between the two vertical plates 2. A pair of corresponding sleeve grooves 4 are concave in the left and right directions on the outer surface of the spherical tank 3. The two crossbars 201 are respectively inserted into the two sleeve grooves 4. The spherical tank 3 is hung above the bottom plate 1 through the two crossbars 201 so that the spherical tank 3 rotates in the up and down directions. A plurality of stirring rods 5 are staggeredly distributed along the spherical cavity wall inside the spherical tank 3. After raw materials and water are injected into the spherical tank 3, the raw materials can be stirred and mixed by the internal stirring rods 5 when the spherical tank 3 rotates up and down.

[0024] A discharge pipe 10 is provided on the surface of the spherical tank 3 on the right side adjacent to the annular tooth track 6. A sealing cover 11 is sleeved on the external thread of the discharge pipe 10. An anti-skid protrusion 14 is provided on the outer surface of the sealing cover 11 along the axial direction. The anti-skid protrusion 14 facilitates the staff to twist the sealing cover 11. When it is necessary to take the material, the sealing cover 11 is removed first, and then the spherical tank 3 is rotated so that the mouth of the discharge pipe 10 is gradually lower than the liquid level of the slurry in the spherical tank 3, and the slurry can be gradually poured out.

[0025] Reference Figure 1 and Figure 2 The annular gear track 6 is arranged in the middle of the outer surface of the spherical tank 3, and a gear 7 meshing with the teeth of the annular gear track 6 is arranged on the front side of the spherical tank 3. The gear 7 is driven by a motor 8 to drive the spherical tank 3 to rotate in the up and down directions. The motor 8 is fixed on the top of the raising platform 13, and the raising platform 13 is fixed on the upper surface of the bottom plate 1. The position of the motor 8 must be on the left side of the spherical tank 3 and staggered with the discharge pipe 10 to avoid interference between the discharge pipe 10 and the motor 8 during the rotation of the spherical tank 3.

[0026] The material delivery channel 9 passes through the vertical plate 2, the cross bar 201 and the tank wall of the spherical tank 3 in sequence, and the tank cavity of the spherical tank 3 is connected to the outside air through the material delivery channel 9. The material delivery channel 9 is used to insert the material delivery pipe, and then pump the raw materials or water into the spherical tank 3. However, it is necessary to control the liquid level height in the spherical tank 3 not to exceed the material delivery channel 9, so as to prevent the slurry from flowing out of the spherical tank 3 along the material delivery channel 9.

[0027] In this embodiment, a roller bearing 12 is embedded in the sleeve groove 4, and the roller bearing 12 is mounted on the outside of the corresponding cross bar 201. The roller bearing 12 can reduce the friction between the groove wall of the sleeve groove 4 and the cross bar 201, so as to reduce the resistance encountered by the spherical tank 3 when rotating in the up and down directions.

[0028] During actual use, the feed pipe is first inserted into the spherical tank 3 along the feed channel 9, and then the raw materials and water are pumped into the spherical tank 3 until the liquid level is close to the feed channel 9. Then the motor 8 is started to control the gear 7 to rotate. The gear 7 and the annular gear 6 cooperate to rotate the spherical tank 3 in the up and down directions. The rotation of the spherical tank 3 causes the stirring rod 5 inside to stir the raw materials to make them fully mixed.

[0029] This embodiment abandons the traditional stirring method of mixing the slurry raw materials with a stirring rod and a stirring blade, thereby reducing the failure rate of the slurry preparation device after long-term use. At the same time, the reduction of mechanical parts can also simplify the subsequent maintenance process, reduce the labor intensity of the staff, speed up the slurry preparation progress, and achieve excellent use effect.

[0030] It should be understood that the above description is merely exemplary and the embodiments of the present application do not limit this.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention are within the scope of protection of the pending claims of the present invention.
