Description

Technical Field

[0001] This utility model relates to the field of automatic sorting technology, specifically to an automatic sorting device for calcium oxide powder. Background Technology

[0002] Quicklime, also known as calcined lime, is a common inorganic compound, mainly composed of calcium oxide, and is usually made by burning limestone. If dolomite is used as the raw material, it is called magnesium lime, which contains both calcium oxide and magnesium oxide, thus also functioning as a magnesium fertilizer. Shellfish, rich in calcium carbonate, are also an important raw material for lime production; the shell lime known as "shell lime" in coastal areas is made from burned shellfish. Quicklime has a strong ability to neutralize soil acidity, quickly correcting it. In addition, it also has insecticidal, weed-killing, and disinfectant properties. After calcium oxide powder is actually prepared, it usually needs to be sorted to meet the diverse needs of different customers. For example, an automatic sorting device for calcium oxide powder with application number 202122130130.5 can automatically and quickly sort and perform secondary sieving on the automatically detected calcium oxide powder, saving manpower and time, improving overall processing efficiency, reducing production costs, increasing economic benefits, and facilitating widespread promotion and use. However, the existing technology has certain limitations in practical applications. From the perspective of material placement, when calcium oxide powder is placed on the conveyor belt, there is a lack of independent temporary placement space. Based on the diffusion characteristics of the material during the conveying process, when the material is in an unconstrained state, it is very easy to diffuse to the surroundings under the action of centrifugal force generated by the rotation of the conveyor belt and its own gravity. This results in each sorting zone being unable to carry a lot of material. If there is too much material, different types of calcium oxide powder are very easy to be mixed, affecting the sorting purity. From the perspective of material delivery, during the process of the pusher plate pushing the material towards the drum screen, according to the flow pattern of bulk materials, the stacked material will undergo lateral displacement due to the pushing force of the pusher plate, moving towards both ends of the pusher plate. This often results in some material remaining on the conveyor belt. If the operator reduces the amount of material stacked in the sorting area to avoid material residue, it will reduce the sorting efficiency and bring many inconveniences to actual use.

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0013] Please see Figures 1 to 4This utility model provides a technical solution: an automatic calcium oxide powder sorting device, including a conveyor belt 1 and multiple pneumatic pushers 7 disposed on the right side of the conveyor belt 1. The working principle of the conveyor belt 1 and the pneumatic pushers 7 is consistent with the technical solution of an automatic calcium oxide powder sorting device disclosed in patent application number 202122130130.5. Simultaneously, a drum screen is also disposed on the left side of the conveyor belt 1. The structure and working method of this drum screen are also the same as those disclosed in the aforementioned patent document; therefore, this part will not be elaborated upon here. Multiple partition plates 2 are uniformly fixedly connected to the outer circumference of the conveyor belt 1, and multiple pushers 4 capable of moving left and right on the outer circumference of the conveyor belt 1 are disposed between two partition plates 2. The pushers 4 between two partition plates 2 can... The components are combined to form a complete "long strip". When the long strip moves left and right between the two partition plates 2, it can completely push the material between them away from the conveyor belt 1. The drive end of the pneumatic push rod 7 is fixedly connected to a push plate 6 that can abut against the push block 4 on one side. When the pneumatic push rod 7 is working, it can drive the push plate 6 to move closer to or away from the push block 4. A second synchronous magnetic block 11 is fixedly installed in each of the multiple push blocks 4, and a third synchronous magnetic block 12 is embedded on the right side of the push plate 6 to make the push block 4 move synchronously with the push plate 6. Therefore, with the help of the second synchronous magnetic block 11 and the third synchronous magnetic block 12, when the push plate 6 contacts the push block 4, although the second synchronous magnetic block 11 and the third synchronous magnetic block 12 do not contact each other, the magnetic force that attracts each other will cause the push block 4 to move synchronously with the push plate 6 when the push plate 6 moves closer to the pneumatic push rod 7.

[0014] Please see Figures 1 to 4 Multiple first limiting strips 5 are fixedly connected to the outer periphery of the conveyor belt 1 between two adjacent partition plates 2. Second limiting strips 8 are fixedly connected to the front and rear sides of the partition plates 2. The first and last push blocks 4 between two adjacent partition plates 2 are slidably connected to their corresponding second limiting strips 8 from front to back. The last push block 4 and one side of the first push block 4 are respectively attached to the partition plate 2. After removing the first and last push blocks 4 from front to back, the bottom ends of the other multiple push blocks 4 are slidably connected to their corresponding first limiting strips 5. The bottom end of the push block 4 is engaged with the first limiting strip 5. Therefore, although the push block 4 can slide along the axial direction of the first limiting strip 5, it will not detach from the first limiting strip 5.

[0015] Both ends of the first limiting strip 5 are fixedly connected to baffles 3. The baffles 3 prevent the push block 4 from sliding out from both ends of the first limiting strip 5.

[0016] Synchronization slots 9 are provided on the rear side of multiple push blocks 4, and one side of one of the two push blocks 4 that abut against each other is fixedly connected to a first synchronization magnetic block 10 that is inserted into the synchronization slot 9 of the other push block 4, and a second synchronization magnetic block 11 is fixedly connected to the inner side of the synchronization slot 9. Therefore, when adjacent push blocks 4 collide with each other, the second synchronous magnetic block 11 and the first synchronous magnetic block 10 can make the adjacent push blocks 4 collide tightly, and the first synchronous magnetic block 10 can also significantly improve the stability when multiple push blocks 4 move synchronously. Meanwhile, as the conveyor belt 1 continues to rotate around the drive roller (which is used to drive the conveyor belt 1 to rotate), during the process of the portion of the conveyor belt 1 equipped with push blocks 4 passing around the drive roller, adjacent push blocks 4 will be separated, and the first synchronous magnetic block 10 will then separate from the second synchronous magnetic block 11 and slide out of the synchronous groove 9. After this portion of the conveyor belt 1 passes the drive roller, the adjacent push blocks 4 will re-abut against each other, and the first synchronous magnetic block 10 will be inserted back into the synchronous groove 9 and re-attracted to the second synchronous magnetic block 11.

[0017] In summary, when this automatic calcium oxide powder sorting device is in use, the conveyor belt 1 operates continuously and separates the calcium oxide powder into multiple independent material units through the separator plate 2. When the material is conveyed to the designated sorting position, the pneumatic push rod 7 drives the push plate 6 to move. With the help of the magnetic force of the third synchronous magnetic block 12 and the second synchronous magnetic block 11, the push block 4 moves synchronously, so that the combined "long plate" completely pushes the material in the corresponding area away from the conveyor belt 1 to complete the sorting. During the circulation of the conveyor belt 1 around the drive roller, the push block 4 can automatically separate and rotate to adapt to the shape of the conveyor belt. Through the adsorption effect of the first synchronous magnetic block 10 and the second synchronous magnetic block 11, it quickly resets and recombines. With the limiting and guiding of the first limit bar 5, the second limit bar 8 and the baffle 3, it is ensured that the push block 4 moves stably without detaching during continuous operation, thereby realizing continuous, automated and efficient sorting of calcium oxide powder, and greatly improving the sorting accuracy and operation efficiency.

[0018] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
