Example 2:
when the waste chalk end recycling and reprocessing equipment is in actual use: the device is usually used in non-teaching time, for example, after a student erases a blackboard after class, the shielding piece 20 is rotated to enable the second blocking piece 22 to be adsorbed on the surface of the blackboard, the air pump 10 at one end of the object placing plate 110 is started to blow chalk ends and chalk dust on the object placing plate 110 into the grinding assembly 30 at the other end, the grinding assembly 30 extrudes and crushes the chalk ends and the respective dust in the base body 34, the control panel 36 controls the cavity in the detection probe 35 to detect after the extrusion and crushing work is finished, the height of the crushed materials in the cavity is extruded and crushed, when the processed chalk powder reaches the height position of the detection probe 35 in the cavity, the detection probe 35 feeds a detection signal back to the control panel 36, the control panel 36 controls the opening and closing valve 37 to open and discharge the chalk powder in the cavity to the solidification assembly 50 through the conveying pipeline 40, and the stirring shaft 54 stirs the chalk powder, and an adhesive can be added to enable the reconstructed chalk to have the adhesion performance with the blackboard after writing, after the materials are stirred, the third motor 58 drives the rotating disc 57 to rotate, so that the plane with the blanking holes 571 is placed at the bottom of the stirring chamber 55, and the materials can fall into the die box 56 along the blanking holes 571 to realize reconstructed chalk.
Statistics shows that nearly 30 boxes of 100 chalks are required for one teaching class on average every year, one box of 100 chalks is about 10 yuan, about 8-9 boxes of 30 boxes of chalks can be recovered by the waste chalk end recovery and reprocessing equipment provided by the invention, about 80-90 yuan can be saved for one teaching class in one year, about 2400-2700 yuan can be saved in chalk cost according to 30 classes in one school, and more importantly, the dust content in air in a classroom is effectively reduced through the waste chalk end recovery and reprocessing equipment provided by the invention, and the teaching environment is optimized.
Meanwhile, through comparison, due to the fact that the adhesive is added to the recycled and rebuilt chalk, writing fluency on the blackboard is superior to that of chalk used before recycling, and chalk powder generated in the writing process is less.
The above disclosure is only for the purpose of illustrating the preferred embodiments of the present invention, and it is therefore to be understood that the invention is not limited by the scope of the appended claims.
