Technical Field
[0001] The utility model relates to the technical field of cement clinker, in particular to a high-belite clinker stirring device. Background Art
[0002] Belite is a dicalcium silicate solid solution containing a small amount of aluminum oxide, iron oxide, sodium oxide, potassium oxide, magnesium oxide and other oxides. It is generally referred to as B ore. Belite is an important mineral component in Portland cement. It can effectively improve the strength of cement clinker and reduce energy consumption and carbon emissions in the cement production process. The main raw materials of Portland cement clinker are limestone and clay. The production of raw materials requires a series of crushing, batching and grinding processes. After calcining, the raw materials can be prepared into cement clinker. Cement clinker needs to be stirred during production.

The outer ring stirring mechanism is driven by the motor to rotate, and the outer ring stirring mechanism stirs its outer ring cement clinker, the first bevel gear drives the second bevel gear to rotate, and the second bevel gear drives the third bevel gear to rotate, so that the third bevel gear and the second bevel gear rotate in opposite directions, and the third bevel gear drives the inner ring stirring mechanism, so that the inner ring stirring mechanism stirs its inner ring cement, and the first stirring block and the second stirring block cooperate to further stir the inner ring cement clinker, so as to achieve the purpose of fully and uniformly stirring its cement clinker and preventing the cement clinker from sticking to the inner wall of the box body.
[0004] However, the above patent still has certain shortcomings when used: although it can perform multi-directional stirring operations on the internal clinker through stirring mechanisms at multiple different positions, the relative positions of the upper and lower layers of raw materials remain unchanged during stirring, and the heavier components will settle to the bottom, while the lighter components will gradually move to the top layer of the raw materials, thereby making it impossible for the various clinker raw materials to be fully mixed, affecting the overall stirring and mixing effect, and when adding the clinker, due to the limitations of the position of the feed port, the added raw materials will be put in large quantities and accumulated in specific positions, thereby making it impossible for other positions to fully receive the raw materials, thereby making the initial mixing degree of the raw materials poor during stirring, the subsequent operating pressure is high, and the overall use effect is not very ideal.
[0005] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0030] According to an embodiment of the utility model, a high-belite clinker stirring device is provided.
[0031] The present invention is now further described in conjunction with the accompanying drawings and specific implementation methods.

A plurality of groups of connecting strips 3 are installed around, and a pushing plate 4 is fixedly installed at the bottom position of the connecting strips 3, and the bottom end of the pushing plate 4 is in contact with the top surface of the distribution plate 7. The discharge pipe 9 is a hollow structure, and a plurality of groups of dispersion rods 11 are installed around the inner surface of the mixing barrel 1 below the supporting plate 20. When the density of the blocking block 21 and the discharge pipe 9 is large, there is no need to open a gap between the two, and when the density is small, it is necessary to open a gap between the two to ensure that the raw materials discharged from the feeding port 8 will not accumulate on the supporting plate 20 when the blocking block 21 and the discharge pipe 9 are switched, so as to ensure that the raw materials can smoothly fall into the interior of the device. Since the gap is also opened at the corresponding position, the raw materials falling from the gap will not affect the overall raw material distribution effect.

Personnel can open a gap at the corresponding position according to needs, and no further details will be given here.
[0032] In one embodiment, a circulation drum 12 is symmetrically installed on the surfaces of both sides of the mixing barrel 1, a spiral dragon 13 is provided in the middle position inside the circulation drum 12, one end of the spiral dragon 13 passes through one side of the circulation drum 12 and is connected to the second motor 10, and a reflux port 19 and a circulation port 16 are respectively provided at the positions where the two ends of the circulation drum 12 are connected to the surface of the mixing barrel 1. The circulation port 16 and the reflux port 19 are arranged to lift and circulate raw materials at different levels, so that raw materials at different positions can be fully in contact with each other, thereby improving the mixing effect of the raw materials.
[0033] In one embodiment, a plurality of groups of stirring blades 14 are evenly installed around the surface of the driving shaft 6 below the dispersion rod 11, a scraper 15 is fixedly installed at the bottom end of the driving shaft 6, and the scraper 15 is in contact with the inner wall of the mixing barrel 1. The stirring blades 14 are provided to stir and mix the added clinker ingredients for subsequent use.
[0034] In one embodiment, feed ports 2 are symmetrically provided on both sides of the top of the mixing barrel 1. The provision of the feed ports 2 facilitates the addition and use of various components of the clinker and facilitates subsequent mixing processing.
[0035] In one embodiment, support legs 17 are symmetrically installed on both sides of the bottom of the mixing barrel 1, and the entire device can be fixed by the support legs 17, so as to enhance the overall stability in use.
[0036] In one embodiment, a discharge port 18 is provided at the middle of the bottom of the mixing barrel 1. The setting of the discharge port 18 facilitates the discharge of the high-belite clinker after mixing, which is convenient for subsequent use.
[0037] In one embodiment, the size of the discharge pipe 9 and the size of the blocking block 21 are both larger than the size of the feeding port 8. The size setting is to ensure that the feeding port 8 can be successfully blocked and the discharge is smooth, so that the raw materials will not fall during blocking and can be discharged smoothly during discharge.
[0038] In one embodiment, the scraper 15 is a U-shaped structure, and the U-shaped structure is provided to ensure that the scraper 15 can fully scrape the side walls and the bottom of the mixing barrel 1, thereby preventing the raw materials from adhering to the surface and causing insufficient mixing of the raw materials.
[0039] Working principle: In actual use, personnel can add various clinker raw materials involved in the production of high Belite clinker through the feed port 2 on the top of the mixing barrel 1. At this time, the added clinker raw materials will fall to the top of the distribution plate 7 for temporary retention, and then the operation of the first motor 5 can drive the drive shaft 6 to rotate. At this time, the push plate 4, the carrier plate 20 and the stirring blade 14 connected to the drive shaft 6 will all rotate synchronously. The rotation of the push plate 4 can push the raw materials on the surface of the distribution plate 7, so that the raw materials can be moved to different positions of the feed. At the material port 8, when the discharge pipe 9 on the surface of the carrier plate 20 is aligned with the feeding port 8, the raw materials on the top of the distribution plate 7 can be discharged smoothly. Since the feeding port 8 is evenly arranged at different positions on the surface of the distribution plate 7, the raw materials can be evenly put in through it, so that the inside of the mixing barrel 1 can evenly receive the raw materials. Similarly, when the raw materials are stirred, the raw materials added subsequently can also be evenly put into different positions of the raw materials being stirred, thereby improving the initial uniformity and facilitating better subsequent use. The surface is also evenly provided with several groups of blocking blocks 21 and discharge pipes 9 corresponding to the feeding port 8, and the discharge pipes 9 are arranged at intervals, so that excessive discharge of raw materials on one side can be avoided, so that the raw materials can be evenly delivered to different positions. Then the raw materials delivered will fall to the dispersion rod 11, and through the collision and blocking with the dispersion rod 11, not only the raw materials can be dispersed, but also the raw materials can be distributed for a second time, further avoiding excessive accumulation of raw materials on one side and improving the overall use effect. Then the raw materials that fall to the bottom can be continuously stirred and mixed by the stirring blades 14, and the raw materials at the bottom position can be continuously discharged through the circulation port 16 while stirring. At this time, this part of the raw materials can be circulated to the top layer of the raw materials through the spiral dragon 13 and discharged from the reflux port 19. Such a circulation operation can effectively improve the mixing effect of raw materials at different levels, avoid stratification of raw materials to reduce the overall mixing effect, can effectively improve the overall stirring effect, and facilitate better use. The device as a whole has the advantages of feeding dispersion, good stirring effect and high material mixing degree.
