[0025] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0026] like Figure 1-2 As shown, a multi-stage grinding device for producing calcium oxide of the present invention comprises a frame 1, the frame 1 is connected to a grinding machine case 2, the grinding machine case 2 is connected to a feed hopper 201, one side of the grinding machine case 2 is connected to a crushing motor, the output end of the crushing motor is connected to a transmission mechanism, the transmission mechanism is provided with multiple output ends, each output end of the transmission mechanism is connected to a crushing roller 3, both sides of the inner wall of the grinding machine case 2 are connected to side plates 202, the side plates 202 are connected to multiple rolling racks 203, the multiple rolling racks 203 are engaged with adjacent crushing rollers 3, one side of the inner wall of the grinding machine case 2 is hinged with a first screening plate 4, the first screening plate 4 is connected to a vibration motor 4001, the first screening plate 4 is arranged at a certain angle, one side of the inner wall of the grinding machine case 2 is connected to a mounting seat 204, the inner wall of the mounting seat 204 is connected to a spring 205, and the other end of the first screening plate 4 is movably connected between the end of the spring 205 and the inner wall of the grinding machine case 2;

[0027] The grinding mill case 2 is connected to a first transmission pipe 206 on the lower side of the first screening plate 4, and a second transmission pipe 207 is connected to the bottom side of the grinding mill case 2. The first transmission pipe 206 and the second transmission pipe 207 are both connected to the secondary grinding mill case 5, and the secondary grinding mill case 5 is connected to a grinding motor 501. The output end of the grinding motor 501 is connected to a rotating rod 502, and anti-slip round rods 503 are connected on both sides of the end of the rotating rod 502. The anti-slip round rods 503 are rotatably connected to the rolling grinding roller 504. The secondary grinding mill case 5 is provided with a switch door 505, and the inner wall is slidably connected to the second screening plate 506. The rolling grinding roller 504 is contact-connected to the upper side of the second screening plate 506, and the bottom of the secondary grinding mill case 5 is detachably connected to the aggregate box 6.

[0028] In the embodiment of the present case, the calcium oxide raw material is put into the grinding mill case 2 through the feed hopper 201, and the calcium oxide raw material first passes between the crushing rollers 3. The crushing motor drives the crushing rollers 3 to engage with each other through the transmission mechanism, and cooperates with the rolling racks 203 of the side plates 202 on both sides to perform primary crushing of the calcium oxide. The crushed calcium oxide falls to the upper side of the first screening plate 4, and the vibration motor 4001 drives the first screening plate 4 to vibrate the screening material, leaving the calcium oxide with larger particles on the first screening plate 4, and then transmits it from the first transmission pipe 206 to the upper side of the second screening plate 506 of the secondary grinding mill case 5. It should be noted that when the vibration motor 4001 drives the first screening plate 4 to vibrate, one end of the vibration plate 4 slightly changes the hinge angle, and the other end slightly changes its position between the spring 205 and the inner wall of the grinding mill case 2, thereby changing the setting angle of the first screening plate 4, thereby enhancing the filtering and screening effect and preventing the first screening plate 4 from getting stuck and piling up materials;

The two grinding rollers 504 rotate with the rotating rod 502 as the axis, and at the same time, they are in contact with the second sieve plate 506 to generate friction to prevent the calcium oxide from falling off. The round rod 503 is used as the axis to realize self-rotation, and then the grinding rollers 504 crush and grind the calcium oxide on the second sieve plate 506. The calcium oxide with qualified particle size passes through the second sieve plate 506 and falls into the collection box 6 for collection. Subsequently, the switch door 505 is opened to take out the second sieve plate 506 for cleaning, and the collection box 6 is removed for unloading.

[0030] In summary, such a structural design can achieve the effects of automatic crushing, first screening, rolling, second screening and automatic aggregation, automatically realize multi-stage grinding and multi-stage screening, which can improve the degree of production automation, improve usability, and thus improve the crushing and grinding efficiency of calcium oxide.

In fact, other structural shapes that are convenient for use with multiple transmission effects can also be considered according to specific circumstances.

[0032] Preferably, anti-rebound plates 208 are connected to both sides of the inner wall of the grinding mill case 2. Such a structural design can prevent the bulk material from directly rebounding onto the inner wall of the grinding mill case 2 when the crushing roller 3 is crushed, thereby extending the service life of the grinding mill case 2. In fact, other structural shapes that have a protective effect on the inner wall of the grinding mill case 2 can also be considered according to specific circumstances.
