[0002] A cement roller press is a grinding equipment used in cement production. It extrudes materials through two relatively rotating rollers, thereby realizing the crushing and grinding of materials. The feeding device is an important part of the roller press, and its main function is to feed materials between the rollers of the roller press to ensure the normal operation of the roller press and improve the grinding efficiency.

[0003] When the roller press is working, first, the materials need to be sent above two rotating solid grinding rollers through the feeding device, and are continuously brought into the roller gap by the extrusion rollers. After being subjected to high pressure, the internal crystal structure of the materials is completely destroyed, and the material mechanism is changed, so that the dense material cake and powder are discharged from the discharge port.

In addition, after the cement raw materials are roll-pressed, they cannot be screened in real time, resulting in inconsistent quality of the produced cement raw materials. Therefore, a feeding device for a cement roller press is proposed to solve the above problems. Summary of the Utility Model

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] Referring to Figure 1 and Figure 2 , an embodiment provided by the present invention: A feeding device for a cement roller press, including a body 1, a feeding assembly is fixedly connected to the top end of the body 1, and the feeding assembly can ensure uniform feeding of cement raw materials. A first vibrating sieve plate 9 is fixedly connected to the inner top end of the body 1 from front to back in an inclined manner. On the left and right sides of the middle and rear ends of the top of the first vibrating sieve plate 9, first guide plates 10 are fixedly connected. At the rear end of the body 1, a first guide pipe 11 is fixedly connected between the rear ends of the two first guide plates 10. At the middle and lower part of the front end of the body 1, a second motor 12 is fixedly connected. Both output ends of the second motor 12 are fixedly connected with second rotating shafts 13. Worms 15 are fixedly connected to the outer sides of the two second rotating shafts 13. The far ends of the second rotating shafts 13 are rotatably connected to support plates 14, and the rear ends of the two support plates 14 are fixedly connected to the front end of the body 1. At the top ends of the second rotating shafts 13 at the front end of the body 1, third rotating shafts 17 are rotatably connected, and the rear ends of the two third rotating shafts 17 are rotatably connected to the rear end of the body 1. Worm gears 16 are fixedly connected to the front ends of the third rotating shafts 17, and the worm gears 16 are meshed with the worms 15 on the same side uniformly. Pressing rollers 18 are fixedly connected to the outer sides of the third rotating shafts 17 inside the body 1. A screening assembly is arranged at the bottom end of the pressing roller 18 in the body 1, and the screening assembly is used to keep the insufficiently crushed cement inside the body 1. A second guide pipe 23 is fixedly connected to the rear end of the body 1 behind the screening assembly. A discharge port 21 is opened at the bottom end of the body 1. A collection assembly is fixedly connected to the rear end of the body 1, and the rear ends of the first guide pipe 11 and the second guide pipe 23 are both located inside the collection assembly.

[0026] Pour the cement raw materials to be ground into the feeding component, and then control the feeding speed through the feeding component to make the cement raw materials evenly enter the main body 1. The first vibrating sieve plate 9 screens the cement raw materials to ensure that the larger particles in the cement raw materials remain on the first vibrating sieve plate 9, preventing the larger particles from damaging the pressure rollers 18. By starting the second motor 12, the two second rotating shafts 13 and the same-side worm gears 15 rotate in the same direction. The thread directions of the two worm gears 15 are opposite, so the two worm wheels 16 are driven to rotate in the opposite direction, and thus the third rotating shaft 17 drives the two pressure rollers 18 to roll and grind the cement raw materials into an appropriate size. The screened component screens the ground cement raw materials. The qualified ones flow out through the discharge port 21, and the unqualified ones and the large particles on the first vibrating sieve plate 9 enter the collection component through the second guide pipe 23 and the first guide pipe 11 respectively, and then are sent to the crushing mechanism by the collection component for re-crushing.

[0027] Refer to Figure 1 and Figure 4 As shown in FIGS.

[0028] The cement raw materials are poured into the feed hopper 2 for storage. When feeding the pressure rollers 18 starts, the first motor 8 is started to drive the first rotating shaft 7 to rotate. The first rotating shaft 7 drives the distributing roller 5 to rotate. When a part of the distribution grooves 6 on the distributing roller 5 coincides with the position of the material dropping port 4, the cement raw materials in the distribution grooves 6 fall into the interior of the main body 1 through the material dropping port 4. By controlling the rotation speed of the first rotating shaft 7, the pressure rollers 18 can be evenly and continuously fed. According to the rolling speed of the pressure rollers 18, the rotation speed of the first rotating shaft 7 is controlled to prevent too much feeding, which may cause the cement raw materials not to be fully compressed and crushed between the pressure rollers 18, thus affecting the crushing effect and particle size distribution of the cement raw materials.

[0029] Refer to Figure 2 and Figure 3, the screening assembly includes two second guide plates 19 which are respectively and relatively inclined and fixed on the left and right sides inside the main body 1. At the relatively inclined ends of the two second guide plates 19, scraping plates 20 are fixedly connected respectively. In the middle and lower part between the second guide plates (19), a second vibrating sieve plate 22 is fixedly connected. The second vibrating sieve plate 22 is fixedly inclined backward. The tops of the scraping plates 20 are respectively in contact with the outer bottom ends of the adjacent pressure rollers 18. The second material guiding pipe 23 is located at the rear side of the second vibrating sieve plate 22. The length and width of the discharge port 21 are the same as those between the bottoms of the two second guide plates 19.

[0030] When the two pressure rollers 18 are grinding against each other, the two scraping plates 20 scrape off the cement raw materials ground on the outer sides of the same-side pressure rollers 18 and let them fall on the second vibrating sieve plate 22. Through the screening of the second vibrating sieve plate 22, the qualified cement raw materials flow out through the discharge port 21, while the unqualified cement raw materials enter the collection assembly through the second material guiding pipe 23.

[0031] Refer to Figure 1 and Figure 5 , the collection assembly includes a collection box 24. At the top end of the collection box 24, a centrifugal pump 25 is fixedly connected. At the input end of the centrifugal pump 25, a feed pipe 26 is fixedly connected. At the output end of the centrifugal pump 25, a discharge pipe 27 is fixedly connected. The front end of the collection box 24 is fixedly connected to the rear end of the main body 1. The feed pipe 26 extends to the inner bottom end of the collection box 24. The rear ends of the first material guiding pipe 11 and the second material guiding pipe 23 are both located inside the collection box 24.

[0032] Connect the end of the discharge pipe 27 to the inlet of the crushing mechanism. The large particles and the unqualified cement raw materials enter the collection box 24 through the first material guiding pipe 11 and the second material guiding pipe 23 respectively. Start the centrifugal pump 25 to suck the items inside the collection box 24 through the feed pipe 26 and enter the crushing mechanism through the discharge pipe 27.

[0033] Working principle: Pour the cement raw materials to be ground into the feed hopper 2, and then control the rotation speeds of the first rotating shaft 7 and the distributing roller 5 by starting the first motor 8, so that the cement raw materials in the distribution grooves 6 on the distributing roller 5 can evenly fall on the first vibrating sieve plate 9. Screen the cement raw materials through the first vibrating sieve plate 9, leave the larger particles in the cement raw materials on the first vibrating sieve plate 9, and then let them fall into the collection box 24 through the first material guiding pipe 11, while the cement raw materials fall on the two pressure rollers 18. Start the second motor 12 to drive the two pressure rollers 18 to grind against each other, grind the cement raw materials into a suitable size, and then pass through the second vibrating sieve plate 22. The qualified ones flow out through the discharge port 21, while the unqualified cement raw materials enter the collection box 24 through the second material guiding pipe 23. Start the centrifugal pump 25 to make it return to the crushing mechanism for re-crushing.

[0034] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
