Description

Technical Field

[0001] This utility model relates to the field of cement powder impurity removal technology, and in particular to a cement powder impurity removal mechanism. Background Technology

[0002] As is well known, fineness refers to the overall coarseness of cement particles. The finer the cement particles, the larger the surface area for reaction with water, resulting in a faster and more complete hydration reaction and higher early strength. The powdered cement material after crushing and grinding contains some particulate impurities, which need to be removed from the cement powder.

[0003] In existing technologies, the cement powder needs to be sieved and dispersed using a screen, and a magnetic rack is also needed to remove magnetic impurities carried in the cement powder to ensure its quality. Currently, in some factories, the equipment for sieving cement powder and screening magnetic impurities is separate, leading to operational inconvenience. Although existing technologies provide various devices that combine sieving cement powder and screening magnetic impurities, problems such as inconvenient screen replacement and difficult cleaning of magnetic impurities still exist. Therefore, a cement powder impurity removal mechanism needs to be designed to solve these problems.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0026] See Figure 1 , Figure 2 , Figure 3 and Figure 4 This utility model provides a cement powder impurity removal mechanism, comprising: The frame 1 is equipped with a cleaning and disassembly mechanism. It should be noted that this mechanism facilitates the combination of cement powder screening and magnetic impurity screening. Moreover, the screen is easy to replace and the magnetic impurities are easy to clean, making it convenient to use. The impurity removal and disassembly mechanism includes a lower housing 2, an upper housing 3, an impurity removal frame 4, a vertical plate 5, an electromagnetic rod 6, a square block 9, a connecting plate 10, a T-shaped insert block 11, and a limiting counterweight frame 19. The lower housing 2 is fixedly connected to the frame 1. The electromagnetic rod 6 is fixedly installed inside the impurity removal frame 4. It should be noted that the electromagnetic rod 6 is used to remove magnetic impurities in cement powder. When the electromagnetic rod 6 is led out, a wire hole can be opened on the vertical plate 5, and the wire can be led out from the wire hole at the top of the vertical plate 5. The impurity removal frame 4 is fixedly connected to the upright plate 5 and the block 9. The bottom of the block 9 is fixedly connected to the connecting plate 10. The connecting plate 10 is fixedly connected to the T-shaped insert 11. The T-shaped insert 11 is engaged with the lower housing 2. The upright plate 5 is engaged with the upper housing 3. The inner side of the limiting counterweight frame 19 is in contact with the outer side of the lower housing 2 and the upper housing 3.

[0027] With the above structure, when it is necessary to replace the screen and clean magnetic impurities, pull the limiting counterweight frame 19 upward to remove it, then pull the upper housing 3 to the right to move the T-shaped insert block 11 out of the T-shaped insertion hole. Then remove the upper housing 3, remove the impurity removal frame 4 from the upper housing 3, and remove the filter frame 14 from the moving frame 13. This makes it convenient and quick to replace the screen and clean magnetic impurities, and the operation is relatively convenient.

[0028] Specifically, the impurity removal and assembly mechanism also includes a reciprocating lead screw sleeve 12, a moving frame 13, a filter frame 14, a baffle 15, a servo motor 16, and a rotating shaft 17. The reciprocating lead screw sleeve 12 is slidably mounted on the lower housing 2. The moving frame 13 is fixedly connected to the reciprocating lead screw sleeve 12. The filter frame 14 is snapped into the moving frame 13. A screen is fixedly installed inside the filter frame 14. The baffle 15 is fixedly mounted on the side of the filter frame 14. The bottom of the baffle 15 contacts the moving frame 13. The servo motor 16 is fixedly mounted on the frame 1. The output end of the servo motor 16 is fixedly connected to the rotating shaft 17. A reciprocating spiral groove is opened on the outer side of the rotating shaft 17. The reciprocating spiral groove is threadedly connected to the reciprocating lead screw sleeve 12.

[0029] With the above structure, the servo motor 16 is started, and the reciprocating screw sleeve 12 is driven to move laterally back and forth through the reciprocating spiral groove on the outer wall. This allows the moving frame 13 to drive the filter frame 14 to move laterally back and forth, thereby screening and removing impurities from the cement powder.

[0030] Specifically, the bottom of the connecting plate 10 contacts the filter frame 14. It should be noted that the filter frame 14 can be vertically limited so that the filter frame 14 can move stably in the lateral direction.

[0031] Specifically, a square groove 8 is provided on the side wall of the upper housing 3, and a square block 9 contacts the top inner wall of the square groove 8. A T-shaped insertion hole is provided on the top of the lower housing 2, and a T-shaped insertion block 11 is engaged with the T-shaped insertion hole. It should be noted that this facilitates the docking of the upper housing 3 and the lower housing 2.

[0032] Specifically, the bottom of the limiting counterweight frame 19 is in contact with the frame 1. It should be noted that the upper housing 3 can be limited.

[0033] Specifically, a cement powder adding hopper 7 is fixedly installed on the top of the upper casing 3, and a material discharge pipe 18 is fixedly installed on the bottom of the lower casing 2. It should be noted that this facilitates material feeding and discharge.

[0034] Specifically, a sealing gasket is embedded and fixed at the bottom of the upper housing 3. The upper housing 3 is in sealed contact with the lower housing 2 through the sealing gasket. It should be noted that this ensures the airtightness between the upper housing 3 and the lower housing 2.

[0035] Working principle: S1: When performing cement powder impurity removal operation, the cement powder is first added into the equipment through the cement powder adding hopper 7 at the top of the upper casing 3. After the powder enters, it falls into the impurity removal frame 4. At this time, the electromagnetic rod 6 inside the impurity removal frame 4 is in working state, and uses electromagnetic force to adsorb the magnetic impurities contained in the cement powder to complete the initial removal of magnetic impurities. S2: The cement powder removed by magnetic impurities falls into the filter frame 14. The screen inside the filter frame 14 screens the cement powder, intercepting larger particles on the screen. The cement powder that meets the fineness requirements continues to fall through the screen. At the same time, the servo motor 16 is started. The output end of the servo motor 16 drives the rotating shaft 17 to rotate. Since the rotating shaft 17 has a reciprocating spiral groove on the outside and the reciprocating spiral groove is threadedly connected to the reciprocating screw sleeve 12, when the rotating shaft 17 rotates, it drives the reciprocating screw sleeve 12 to slide laterally along the lower housing 2. This drives the moving frame 13, which is fixedly connected to the reciprocating screw sleeve 12, to move laterally back and forth. The moving frame 13 then drives the filter frame 14 to move laterally back and forth synchronously. This reciprocating motion can effectively prevent cement powder from accumulating and clogging on the screen, improve screening efficiency, and ensure the smooth progress of screening. After screening, the cement powder is discharged through the discharge pipe 18 at the bottom of the lower housing 2, completing the entire impurity removal process. S3: When it is necessary to replace the screen or clean magnetic impurities, pull the limiting counterweight frame 19 upward to remove it from the outside of the lower housing 2 and the upper housing 3, thereby releasing the limiting on the upper and lower housings. Then, pull the upper housing 3 to the right to move the T-shaped insert 11 out of the T-shaped insert hole at the top of the lower housing 2. Then, remove the upper housing 3. After that, the impurity removal frame 4 can be removed from the upper housing 3 to clean the magnetic impurities adsorbed on the electromagnetic rod 6. At the same time, remove the filter frame 14 from the moving frame 13 to replace or clean the screen. The operation is convenient and efficient.

Specific embodiments have been used to illustrate the principle and implementation of this utility model. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core idea of ​​this utility model. It should be noted that those skilled in the art can make several improvements and modifications to this utility model without departing from the principle of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
