[0030] The quantitative structure 2 includes a support frame 201. The support frame 201 is of an L-shaped structure. A lead screw 203 is rotatably arranged between the inner side of the support frame 201 and the outer side of the feeding hopper 102. Guide rods 204 are arranged on both sides of the lead screw 203, and a moving block 205 is movably arranged on the outer walls of the guide rods 204 and the lead screw 203.

[0031] A blocking plate 206 is fixedly connected to the top of the moving block 205. A through hole is provided on the outer side of the feed hopper 102, and the through hole is adapted to the blocking plate 206. A motor 202 is installed on the outer side of the support frame 201, and the output end of the motor 202 is fixedly connected to one end of the lead screw 203.

[0032] The crushing structure 3 includes a fixed frame 301. The fixed frame 301 is of a U-shaped structure. One end of the inner side of the fixed frame 301 is rotatably connected to a rotating shaft. The other end of the rotating shaft is fixedly connected to a driving wheel 302. The other end of the driving wheel 302 is provided with a crushing roller 305. The other end of the crushing roller 305 penetrates through the inner side of one end of the crushing box 1 and is rotatably connected to the other inner side. And a driven wheel 304 is installed at one end of the other crushing roller 305. The driving wheel 302 and the driven wheel 304 are connected by a belt 303.

[0033] A partition plate 306 is installed between the inner walls of the crushing box 1. An inclined surface is formed between both ends of the partition plate 306 and the inner wall of the crushing box 1. A discharge hole is provided at the center position of the top end of the partition plate 306. A discharge plate 307 is movably arranged in the discharge hole. Two hinge seats 308 are installed at the bottom end of the discharge plate 307. One end of the outer side of the hinge seat 308 is hinged to an electric cylinder 309. The other end of the electric cylinder 309 is hinged to a support seat 310. The other end of the support seat 310 is connected to the inner wall of the crushing box 1.

[0034] The screening structure 4 includes moving grooves 402 provided on the inner walls of both sides of the crushing box 1. Sliders 403 are slidably arranged in the moving grooves 402. A receiving box 401 is installed between the sliders 403. Fixed blocks 404 are arranged on the inner walls of the four corners of the receiving box 401.

[0035] It should be noted that both the quantitative structure 2 and the crushing structure 3 use the motor 202 as the power source. The motor 202 is connected to an external power supply, and the entire device is connected to an external controller. During use, first, the calcium hydroxide to be crushed is placed into the feed hopper 102. Then, the motor 202 drives the lead screw 203 to rotate. The lead screw 203 will drive the guide rod 204 and the moving block 205 on the outer wall of the lead screw 203 to move. Since the blocking plate 206 is installed on the top end of the moving block 205, when the moving block 205 moves, it will drive the blocking plate 206 to move simultaneously, thus realizing the quantitative transportation of the calcium hydroxide in the feed hopper 102 to the crushing box 1. Then, the motor 202 drives the two crushing rollers 305 to rotate simultaneously. The two rotating crushing rollers 305 crush the calcium hydroxide. The crushed calcium hydroxide will fall onto the partition plate 306. Then, the electric cylinder 309 extends and retracts to drive the discharge plate 307 to open and close, so that the crushed calcium hydroxide can fall into the vibrating screen 406. The vibrating screen 406 will screen the crushed calcium hydroxide. When the vibrating screen 406 vibrates, the vibrator arranged at the bottom end of the fixed block 404 will also vibrate simultaneously, which can increase the vibration rate of the vibrating screen 406 and realize the rapid screening of the crushed calcium hydroxide. When the vibrating screen 406 needs to be replaced, directly remove the plug 405 installed at the bottom end of the vibrating screen 406 from the groove on the top end of the fixed block 404. The calcium hydroxide after screening will fall into the receiving box 401. Then, directly move the receiving box 401 through the slider 403 in the moving groove 402 to pull out the receiving box 401. Then, take out the piston in the discharge hole at the bottom of the receiving box 401 to discharge the crushed calcium hydroxide from the receiving box 401. Through the setting of the quantitative structure 2, the amount of calcium hydroxide transported to the crushing box 1 each time can be accurately controlled, which helps to ensure the stability and consistency in the production process, avoid the change of production quality caused by the fluctuation of the calcium hydroxide feeding amount, and at the same time can avoid the problems of overage or shortage caused by inaccurate transportation, which helps to improve production efficiency, reduce the waste of waste materials and energy, can control the usage amount of raw materials, avoid the cost waste caused by excessive use of calcium oxide, and at the same time, the screening structure 4 can classify the crushed calcium hydroxide according to requirements, so as to meet the requirements of different product specifications, and can quickly replace the vibrating screen 406 according to production needs to adapt to the screening requirements under different particle sizes, which can reduce the downtime, improve the continuity and stability of the production line, and the replaceable vibrating screen 406 can timely remove the accumulation on the screen mesh to avoid affecting the screening effect, which is conducive to extending the service life of the equipment and reducing the maintenance cost.
