It should be noted that for those skilled in the art, several modifications can be made to the present invention without departing from the principle of the present invention, and these improvements and modifications also fall within the protection scope of the claims of the present invention.

[0025] like Figures 1 to 3 As shown, the vertical solid waste grinding system includes an inlet 1, a buffer chamber 2, a crushing and grinding chamber 3, a connecting chamber 4, a screening chamber 5, a support column 6, a support plate 7, casters 8, a separation chamber 9, an adjustable collection frame 10, an upper fixed grinding disc 11, a lower movable grinding disc 12, a telescopic rod 13, a fixed base 14, a screen 15, an adjustable separation partition 16, a reaction force monitoring device 17, a drive motor 18, a fan 19, a movable track 20, fixing bolts 21, a grinding disc inlet 22, and a grinding surface 23. The upper fixed grinding disc 11, the lower movable grinding disc 12, the telescopic rod 13, the fixed base 14, and the reaction force monitoring device 17 are all located in the crushing and grinding chamber 3. The lower part of the screening chamber 5 is connected to the support column 6, and the lower end of the support column 6 is set on the support plate 7. Casters 8 are provided at the bottom of the support plate 7, allowing the entire device to be supported and moved.

[0026] The upper end of the crushing and grinding chamber 3 is provided with a buffer chamber 2, and the upper end of the buffer chamber 2 is provided with a feed inlet 1.

[0027] The upper fixed grinding disc 11 is positioned above the lower movable grinding disc 12. Both the lower end of the upper fixed grinding disc 11 and the upper end of the lower movable grinding disc 12 are provided with grinding surfaces 23. The grinding surfaces 23 on both the upper fixed grinding disc 11 and the lower movable grinding disc 12 are conical surfaces. The upper fixed grinding disc 11 is placed in the grinding chamber 3, which contains a fixed base 14. A telescopic rod 13 is mounted on the fixed base 14. The lower movable grinding disc 12 is positioned above the telescopic rod 13. The telescopic rod 13 drives the lower movable grinding disc 12 to move up and down, thereby adjusting the distance between the two grinding surfaces 23.

[0028] The upper fixed grinding disc 11 is provided with a grinding disc inlet 22, and a number of discharge ports are distributed on the grinding surface 23 at the lower end of the upper fixed grinding disc 11. The discharge ports are connected to the grinding disc inlet 22, and a discharge port 24 is provided at the center of the grinding surface 23 at the upper end of the lower movable grinding disc 12.

[0029] The telescopic rod 13 is a hollow structure, and a discharge channel is provided in the telescopic rod 13, which is connected to the discharge port 24. The telescopic rod 13 has the function of moving the lower movable grinding disc 12, and can allow the ground material to pass through the telescopic rod 13 and fall into the screening chamber 5 below.

[0030] The telescopic rod 13 is mounted on the fixed chassis 14. A rotating chassis 25 is located at the lower end of the telescopic rod 13, and the rotating chassis 25 is rotatably connected to the fixed chassis 14. A drive motor 18 is installed on the grinding chamber 3. The drive motor 18 is connected to the rotating chassis 25 via a transmission mechanism. The drive motor 18 drives the rotating chassis 25 to rotate, thereby rotating the telescopic rod 13 and the lower movable grinding disc 12. The transmission mechanism transmits the power from the drive motor to the rotating chassis 25 to drive its rotation; a gear transmission mechanism may be used for this purpose.

[0031] A reaction force monitoring device 17 is provided on the upper fixed grinding disc 11. The reaction force monitoring device 17 can monitor the axial force on the upper fixed grinding disc 11, and determine whether the grinding is effective by monitoring the axial force on the upper fixed grinding disc 11 during the grinding process. In this embodiment, the reaction force monitoring device 17 is a force sensor.

[0032] The screening chamber 5 is located below the crushing and grinding chamber 3, and a connecting chamber 4 is provided between the screening chamber 5 and the crushing and grinding chamber 3; a fan 19 is provided on one side of the screening chamber 5, and the wind speed of the fan 19 is adjustable.

[0033] On the other side of the screening chamber 5, there is a separation chamber 9. Between the separation chamber 9 and the screening chamber 5, there is a screen 15 with screen holes. The diameter of the screen holes gradually increases from top to bottom.

[0034] Several adjustable separation baffles 16 are provided on one side of the screen 15. The adjustable separation baffles 16 can be moved up and down along the screen 15 to freely separate the screened material for subsequent processing.

[0035] An adjustable collection frame 10 is provided at the end of the separation chamber 9 furthest from the screening chamber 5, and a guide rail device 20 is provided at the same end. The adjustable collection frame 10 is connected to the guide rail device 20 by fixing bolts 21. The guide rail device 20 allows for the up-and-down movement of the adjustable collection frame 10, thus enabling flexible adjustment of its height position to accurately receive screened material at any location. The guide rail device has a locking mechanism that locks the adjustable collection frame 10 in its current position after it has been adjusted to the target position, fixing it in place.

[0036] In use, the grinding system is started by turning on the drive motor 18. Solid waste material is fed in through the feed inlet 1, passes through the buffer chamber 2, and enters the crushing and grinding chamber 3. The solid waste material enters between the upper fixed grinding disc 11 and the lower movable grinding disc 12 through the grinding disc feed inlet 22 on the upper fixed grinding disc 11. The solid waste material is ground by the upper fixed grinding disc 11 and the lower movable grinding disc 12. The movement of the lower movable grinding disc 12 by the telescopic rod 13 keeps the distance between the upper and lower grinding discs at an appropriate position, which not only controls the coarseness of the ground material, but also, since the grinding surfaces 23 are all inclined circular surfaces, the grinding force of the material changes from friction to gravity and friction, and at the same time increases the grinding area and the effective grinding times, greatly increasing the grinding efficiency. At the same time, a reaction force monitoring device 17 is set on the upper fixed grinding disc 11. By monitoring the reaction force, it can be determined whether the distance between the grinding discs is appropriate and whether the grinding is effective.

[0037] The ground material moves downward through the discharge channel in the middle of the telescopic rod 13, and then reaches the screening chamber 15 through the connecting chamber 4. The blower 19 blows air onto the screen 15. Under the action of the blower, the finer material reaches the screen 15 first, and the coarser material reaches the screen 15 later. Therefore, the screen aperture of the screen 15 increases from top to bottom. By controlling the position of the adjustable separation baffle 16, the screened materials of different particle sizes can be freely grouped and collected. The screened material moves along the adjustable separation baffle 16 to the adjustable collection frame 10, which receives the screened material. The adjustable collection frame 10 can be moved up and down to accurately receive the separated material at any position.

[0038] The scope of protection of this utility model is not limited to the above embodiments. Any modifications, equivalent substitutions, and improvements that can be made by those skilled in the art within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
