Description

Technical Field

[0001] This utility model relates to the field of cement clinker cooling technology, specifically to a cement clinker cooling and purification device. Background Technology

[0002] In rotary kiln cooling, sintered clinker enters from the bottom of the kiln and rotates along the kiln cylinder. During this process, it is cooled by the built-in cooling device. By adjusting the orientation of the cooler and the speed of the cooling air, the temperature of the clinker can be reduced quickly.

[0003] For example, a cement clinker cooling device disclosed in Chinese patent CN219869158 U can filter the exhaust air after air cooling to prevent dust inside the cement clinker from being discharged during the exhaust process and affecting the environment, thereby increasing the environmental friendliness of the device. During the filtration process of the annular filter plate, the annular filter plate can also be cleaned in a cycle to avoid the annular filter plate becoming clogged after long-term use and the exhaust efficiency being low, further increasing the practicality of the device.

[0004] The above-mentioned cooling device still has some shortcomings in actual use and needs to be improved. First, after the cement clinker enters the cooling box, it runs in a free fall manner, which results in a limited contact time between the clinker and the cold air, thus limiting the cooling effect. Second, there is only one set of purification components. As can be seen from the attached diagram, the purification components are obviously difficult to bear the entire purification task.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] like Figure 1-2 As shown, this utility model provides a technical solution: a cement clinker cooling and purification device, including a cooling box 1, the top of which is provided with a feed inlet 2, and the upper and middle parts of the inner cavity of the cooling box 1 are respectively provided with an inclined first guide plate 3 and a guide assembly 4.

[0029] like Figure 1-2 As shown, there are multiple sets of flow guiding components 4, which are distributed in an alternating manner.

[0030] like Figure 1 , 4 As shown, the airflow guiding component 4 consists of inclined guide plates. The slope angle of the guide plates in the airflow guiding component 4 is gentler than that of the first guide plate 3. Airflow guide grooves 41 are provided on the guide plates, and multiple sets of stepped protrusions 42 are also provided on the guide plates. Since the air outlet 6 is only located on one side of the guide plate, for example... Figure 1 The second set of guide vanes is positioned away from the air outlet 6. In order to cool the clinker on it, air guide grooves 41 are opened on the guide vanes so that the cooling air (cooling air refers to air drawn from the outside, which is lower in temperature than the clinker, hence the name cooling air) can still come into contact with the clinker and cool it through the air guide grooves 41. The purpose of setting the protrusions 42 is to further slow down the falling speed of the clinker and prolong the contact time between the clinker and the cold air.

[0031] like Figure 2 As shown, the flow guiding component 4 includes a horizontally distributed conveyor belt 44 and a conveyor wheel 43 for driving the conveyor belt 44 to rotate.

[0032] The clinker slides from the first guide plate 3 onto the conveyor belt 44, and the external motor drives the conveyor belt 44 to rotate, thereby causing the material to flow on multiple conveyor belts 44 and increasing the cooling time.

[0033] like Figure 1-2 As shown, a cooling fan 5 is installed on the side wall of the cooling box 1. The arrow in the figure indicates the direction of the cooling air flow. An air outlet 6 is installed in the middle of the inner wall of the cooling box 1. The cooling fan 5 is connected to the air outlet 6 through a pipe. The air outlet 6 is directly facing the air guide assembly 4.

[0034] like Figure 3 As shown, multiple filter chambers 7 are embedded on the cooling box 1 on the opposite side of the air outlet 6. A filter screen 8 is provided on the side of the filter chamber 7 near the flow guide component 4. An activated carbon filter layer 10 and an exhaust port 11 are provided on the other side of the filter chamber 7. A cleaning port 9 is also provided on the filter chamber 7, through which the filter chamber 7 can be cleaned.

[0035] like Figure 5 As shown, the inner wall of the cooling box 1 is provided with multiple sets of cleaning brushes 15. Among them, a set of cleaning brushes 15 is provided between every two sets of filter chambers 7. During the rotation, the cleaning brushes 15 can cover the filter screens 8 on the two sets of filter chambers 7. It should be noted that when the filter screens 8 are working, the cleaning brushes 15 can be placed on the inner wall of the cooling box 1 (horizontally), so it does not affect the operation of the filter screens 8.

[0036] like Figure 1-3 As shown, the side wall of the cooling box 1 is provided with multiple housings 12, and a rotating shaft 13 is provided inside the housing 12. The rotating shaft 13 is driven by an external motor 14. The end of the rotating shaft 13 is connected to the cleaning brush 15 at the corresponding position. Adjacent sets of rotating shafts 13 are connected by a transmission sprocket 17 and a transmission belt 18.

[0037] All cleaning brushes 15 can be connected in pairs via a transmission system to achieve synchronous movement.

[0038] like Figure 1 As shown, the bottom of the cooling box 1 is provided with a discharge port 16. A second guide plate 161 and a screen 162 are respectively arranged from top to bottom in the discharge port 16. The screen 162 is inclined and a discharge port 163 is provided at the lowest point of the screen 162. Dust and clinker are discharged through the discharge port 16. The dust is filtered out through the screen 162 and the clinker is discharged through the discharge port 163, thus achieving separation.

[0039] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0040] During use, cement clinker falls into the cooling box 1 from the feed inlet 2. After being guided by the first guide plate 3, it falls onto the guide assembly 4 below. The cooling fan 5 is started, and cold air is blown out through the air outlet 6 to cool the clinker on the guide assembly 4.

[0041] The clinker slides down sequentially on multiple sets of flow guiding components 4, thereby extending the contact time between the clinker and the cold air and achieving sufficient cooling.

[0042] Cold air carrying dust is blown into the filter chamber 7. The dust is trapped when it passes through the filter screen 8. The airflow passes through the filter chamber 7 and is discharged after being purified by the activated carbon filter layer 10. By periodically turning on the motor 14, the rotating shaft 13 is driven to rotate, which in turn drives multiple cleaning brushes 15 to rotate synchronously. During the rotation, the cleaning brush 15 will come into contact with the two adjacent filter screens 8. Through the relative sliding friction between the filter screen 8 and the cleaning brush 15, the dust on the filter screen 8 is cleaned, preventing the filter screen 8 from clogging.

[0043] In summary, this cement clinker cooling and purification device improves the cooling effect by setting multiple sets of staggered flow guiding components inside the cooling box. During the falling process, the cement clinker comes into contact with the flow guiding components, and the falling speed of the clinker is reduced through collision contact. At the same time, the contact time between the clinker and the cooling air is greatly increased. Furthermore, by setting multiple sets of linked filter chambers, the overall purification effect is greatly increased.
