[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Example 1

[0024] As attached Figures 1 to 4 A dolomite crusher is shown, comprising a base 1 made of metal material and serving as a support. A column 2 is provided above the base 1 and stably connected to the base 1 by welding, so that a feeding mechanism 3 can operate stably. A feeding mechanism 3 is provided above the column 2. The feeding mechanism 3 uses a screw conveyor, which is a common industrial conveying method and is particularly suitable for linear conveying of bulk materials. This method can continuously and evenly convey materials. A microwave device 4 is provided on one side of the feeding mechanism 3. Microwave heating technology is very effective for heat treatment of minerals such as dolomite. Microwaves can quickly heat materials and achieve ideal processing effects in a relatively short reaction time. Microwave heating not only reduces energy consumption but also improves the calcination quality of dolomite, making it easier for subsequent crushing processing.

[0025] At the same time, by adjusting the speed and pitch of the screw 13, the heating time of the material in the microwave device 4 can be accurately controlled, thereby optimizing the heating effect. A crushing box 5 is connected to one side of the microwave device 4. The crushing box 5 is made of metal material. The closed box body can prevent the dolomite debris in the work from entering the environment, and at the same time prevent impurities in the environment from affecting the working process of the crusher. The upper layer of the crushing box 5 is provided with an inclined plate 6. The inclined plate 6 is made of metal material and is arranged below the feeding mechanism 3, so that the dolomite heated by microwaves can regularly enter the crushing area below for crushing operation, and move downward under the action of its own weight, saving energy consumption while also avoiding To avoid the problem of clogging, a pull-out mechanism 7 is provided under the oblique plate 6. The pull-out mechanism 7 is a drawer-type design, which makes the maintenance and replacement of the crushing roller 9 and its related components simple. When the crushing roller 9 needs to be repaired or replaced, the staff can easily pull the entire device out of the crushing box 5, similar to the full-pull-out drawer design in furniture. Electric slide rails 8 are provided on both sides of the pull-out mechanism 7. The electric slide rails 8 are made of high-strength materials and have excellent load-bearing capacity and stability. This design ensures the position accuracy and stability of the crushing roller 9 during high-speed operation and high-intensity crushing, thereby extending the service life of the equipment.

[0026] At the same time, since the electric slide rail 8 runs smoothly and is easy to control, mechanical impact and wear are reduced, and the reliability and durability of the equipment are further improved. The pulling mechanism 7 is provided with a crushing roller 9 through the electric slide rail 8. There are two groups of crushing rollers 9, and the two groups of crushing rollers 9 are evenly arranged along the horizontal direction of the pulling mechanism 7. The surface of the crushing roller 9 is usually made of high-hardness, wear-resistant alloy material or wear-resistant coating, such as wear-resistant alloy cast iron or wear-resistant welding layer, to extend the service life of the equipment. The two crushing rollers 9 rotate relative to each other. By adjusting the gap between the two rollers, the particle size of the discharge can be controlled. A discharge port 10 is provided at the bottom of the pulling mechanism 7. The discharge port 10 is made of stainless steel and has a smooth surface to facilitate the falling of the crushed material.

[0027] Example 2

[0028] Based on Example 1, the solution in Example 1 is further detailed in combination with the following specific working methods. Figures 1 to 4 As shown, see the following description for details:

[0029] As a preferred embodiment, the feeding mechanism 3 includes a feeding port 11, an outer shell 12 and a screw 13. The feeding port 11 is provided at the top of the outer shell 12. The feeding port 11 is larger at the top and smaller at the bottom, which facilitates the entry of materials into the interior of the feeding mechanism 3 and reduces the labor intensity of the staff. A screw 13 is provided at the inner center of the outer shell 12. One side of the screw 13 is connected to a No. 1 motor 14. The screw 13 can carry the material forward and can convey the material continuously and evenly.

[0030] As a preferred embodiment, the microwave device 4 includes a transformer 15, a semiconductor generator 16 and an antenna 17. The semiconductor generator 16 is connected to one side of the transformer 15, and the antenna 17 is provided at the top center of the semiconductor generator 16. Furthermore, the model of the transformer 15 is T552, which provides a variety of turns ratios and is suitable for different impedance matching requirements. The model of the semiconductor generator 16 is HSMS-286X, and the antenna 17 is a cylindrical central cathode (electron source). The electrons are placed in a cylindrical anode. The electrons are attracted by the electrostatic field and flow toward the anode. The stable magnetic field along the axis of the vacuum tube causes the electrons to deviate from their radial path and rotate around the cathode. In the process, oscillations of microwave frequencies are generated, thereby generating microwaves.

[0031] As a preferred embodiment, a waveguide 18 is provided on the outside of the antenna 17, and the waveguide 18 is connected to the internal space of the feeding mechanism 3. Furthermore, the waveguide 18 is a low-loss aluminum waveguide, which optimizes the transmission efficiency of the microwave, ensures that the microwave energy evenly covers the processing area, and performs microwave heating on the dolomite.

[0032] As a preferred embodiment, the pulling mechanism 7 is a rectangular frame structure, and slide rails 19 are provided at the four edges of the outer wall of the pulling mechanism 7. Through the slide rails 19, the staff can easily open and close the pulling mechanism 7, which is convenient for checking and maintaining the internal parts.

[0033] As a preferred embodiment, a sliding block 20 is provided inside the electric slide rail 8. The sliding block 20 can drive the parts above to perform precise displacement. A rotating shaft 21 is provided at the center of the sliding block 20. The sliding block 20 is connected to the crushing roller 9 through the rotating shaft 21. The crushing roller 9 can rotate along the sliding block 20 through the rotating shaft 21.

[0034] As a preferred embodiment, a belt 22 is connected to one side of the rotating shaft 21, and a No. 2 motor 23 is connected to one side of the belt 22. The use of the belt 22 allows the rotating shaft 21 to have a certain degree of elastic adaptability when displacing, preventing the rigid connection of the No. 2 motor 23 from causing the parts to exceed the stiffness design and be damaged during movement.

[0035] The working process of the present invention is as follows: first, the dolomite to be crushed is added into the feeding mechanism 3 through the feeding port 11, and is transported forward by the rotation of the screw 13 to enter the area of ​​the microwave device 4. The dolomite is pretreated with microwaves. After microwave heating, the dolomite can effectively remove internal stress, which is convenient for subsequent crushing. Then it enters the crushing box 5 and falls into the middle of the crushing roller 9. It is crushed into particles under the action of the two sets of crushing rollers 9 rotating in opposite directions. According to production requirements, the gap between the two sets of crushing rollers 9 can be accurately adjusted by the electric slide rail 8 to make the particle size formed by the crushed dolomite adjustable, thereby adapting to different application scenarios. The above is the working principle of this dolomite crusher.

[0036] Finally: The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
