Specifically, the aperture size of the first sieve hole 13 is mainly designed according to the purity of the raw material for producing calcium oxide. The solid particles that do not pass through the first sieve hole 13 reach the bottom of the internal sieve 12 with the action of gravity. By regularly opening the clamping slot 21 to clean the internal sieve 12, the cleanliness of the equipment can be maintained, the workload of impurity removal in the later stage is reduced, and the production efficiency is improved.

[0028] Reference Figure 1-Figure 4 The outer surface of the bottom of the limiting tray 15 is provided with a long hexagonal nut 16, which penetrates the internal sieve shell 12 and the outer sieve shell 11 and is rotatably connected to the rotating shaft 9.

[0029] Reference Figure 1-Figure 4 The second body 4 includes two groups of first screens 17, which are respectively arranged at different heights inside the second body 4. Three groups of vibration motors 6 are arranged around the outer surface of the second body 4 away from the two groups of first screens 17. A material guide trough 22 is fixedly connected to the inner surface of the second body 4 away from the three groups of vibration motors 6.

At the same time, the material and structure of the sealing covers 24 can be selected according to actual needs to meet different production needs and environmental conditions.

[0031] The implementation principle of the raw material screening device embodiment of calcium oxide production in the present application is:

[0032] When the raw materials for calcium oxide production need to be screened, the raw materials are diverted from the feed port 25 through the inlet diverter rod 2 and poured into the first main body 1 to prevent the raw materials from being blocked at the inlet due to excessive flow, thereby affecting production efficiency. The motor 3 and the vibration motor 6 switches are turned on, and the output shaft of the motor 3 drives the rotating shaft 9 to rotate so that the internal sieve shell 12 and the external sieve shell 11 rotate coaxially. The raw materials pass through the first sieve hole 13 for initial centrifugal movement to screen solid particle impurities in the raw materials. The raw materials after passing through the first sieve hole 13 enter the outer sieve shell 11, and the solid particles that do not pass through the first sieve hole 13 reach the bottom of the internal sieve shell 12 with the action of gravity. By regularly opening the clamping groove 21 to clean the internal sieve shell 12, the cleanliness of the equipment can be maintained, the workload of impurity removal in the later stage is reduced, and the production efficiency is improved.

[0033] On the other hand, the raw materials pass through the second sieve hole 14 at the bottom of the outer sieve shell 11 and enter the multi-stage screening device. The vibration motor 6 causes the first sieve 17 and the second sieve 18 in the second main body 4 and the third main body 5 to vibrate, thereby driving the downward screening of the raw materials. At the same time, the inner walls of the second main body 4 and the third main body 5 are made of soft plastic material with dust absorption function, which can effectively reduce the dust overflow during the production process. The calcium oxide production raw materials after multi-stage screening enter the third sieve 20 through the material guide trough, and finally obtain the final screened production raw materials through the discharge port 8.
