Description

Technical Field

[0001] This utility model relates to the field of grate cooler technology, specifically a clinker high-temperature recovery grate cooler device. Background Technology

[0002] In the cement production process, high-temperature recovery grate cooling devices for clinker are crucial for ensuring effective cooling and waste heat recovery. However, existing devices face significant challenges and drawbacks during operation, particularly in the clinker cooling and feeding stages. In traditional high-temperature recovery grate cooling devices, clinker tends to accumulate on the grate due to material characteristics and operating conditions. This accumulation not only affects the uniform cooling of the clinker but can also lead to equipment overload and increased energy consumption. Furthermore, the accumulated clinker lacks an effective dispersion mechanism during feeding, which can cause feeding difficulties and affect the continuity and stability of the production line.

[0003] Traditional grate cooling devices lack efficient clinker dispersion and conveying mechanisms. During the feeding process, the accumulated clinker often fails to form a continuous and uniform material flow due to the natural collapse under gravity. This can easily cause blockage at the feeding port or uneven feeding speed, which in turn affects the normal operation of subsequent processes such as grinding and packaging. This poor feeding not only reduces the continuity and stability of the production line, but may also lead to production safety accidents, increase maintenance costs and downtime.

Below the bottom vibrating plate are several horizontally aligned upper horizontal pipes. Below the upper horizontal pipes are lower horizontal pipes that are horizontally symmetrical to the upper horizontal pipes. Several vertical pipes connect the upper and lower horizontal pipes. Several circular through holes are opened on the outer arc wall of the vertical pipes. An air box is installed on the outer side wall of the grate cooler body. A first fan is installed on the side of the air box away from the grate cooler body.

[0022] 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.

[0023] Please see Figure 1-4 This utility model provides a technical solution:

[0024] See Figure 1 and Figure 4As shown, a high-temperature recovery grate cooling device for clinker includes a grate cooler body 1. A feed box 2, penetrating into the grate cooler body 1, is fixedly installed on one side of the upper surface of the grate cooler body 1. A buffer cooling mechanism is provided inside the feed box 2. The buffer cooling mechanism includes several vibrating plates 13 vertically and intersectingly arranged on the inner wall of the grate cooler body 1. The vibrating plates 13 are hinged to the inner wall of the feed box 2 and are inclined downwards towards the center of the feed box 2. An mounting block 11 is installed below each protrusion 14 on the inner arc wall of the feed box 2. A spring 12 is installed on the upper surface of the mounting block 11. The top of the spring 12 is connected to the vibrating plate 14. The lower surfaces of the two parts are connected. The inner wall of the feeding box 2 is provided with several horizontally aligned upper horizontal pipes 15 below the bottom vibrating plate 13. Below the upper horizontal pipes 15, there are lower horizontal pipes 16 that are horizontally symmetrical with the upper horizontal pipes 15. Several vertical pipes 17 are connected between the upper horizontal pipes 15 and the lower horizontal pipes 16. Several circular through holes 18 are opened on the outer arc wall of the vertical pipes 17. A wind box 3 is installed on the outer side wall of the grate cooler body 1. A first fan 4 is installed on the side of the wind box 3 away from the grate cooler body 1. The ends of the upper horizontal pipes 15 and the lower horizontal pipes 16 near the wind box 3 pass through the feeding box 2 and the grate cooler body 1 to the wind box 3 and are connected to the wind box 3.

[0025] In the specific implementation process, a buffer cooling mechanism is set in the feeding box 2 for preliminary cooling and buffering of the clinker. The vibrating plate 13 is inclined downwards towards the center of the feeding box 2, which helps to disperse and buffer the clinker when it falls. The mounting block 11 provides support for the spring 12. The spring 12 and the vibrating plate 13 enable the clinker to vibrate when it falls, further promoting the cooling effect. The upper horizontal pipe 15 and the lower horizontal pipe 16 are connected by several vertical pipes 17. Several circular through holes 18 are opened on the outer arc wall of the vertical pipe 17. These through holes facilitate the circulation of cooling air. The first fan 4 can reach the upper horizontal pipe 16 through the air box 3. Cooling air is supplied to the upper horizontal pipe 15 and lower horizontal pipe 16 and transmitted to the feeding box 2 through the circular through hole 18 of the vertical pipe 17. When the clinker enters the main body 1 of the grate cooler through the feeding box 2, it first falls on the vibrating plate 13. Due to the inclined design of the vibrating plate 13 and the buffering effect of the spring 12, the clinker is dispersed and initially cooled. At the same time, the first fan 4 is started, and cooling air is supplied to the upper horizontal pipe 15 and lower horizontal pipe 16 through the air box 3. The cooling air flows out through the circular through hole 18 on the vertical pipe 17 to further cool the clinker. The cooled air and the residual heat in the clinker can be recovered and utilized to improve energy utilization efficiency.

[0026] See Figure 4As shown, the vibrating plate 13 has an inclination angle of 30 degrees. Several protrusions 14 are installed on the upper surface of the vibrating plate 13. A guide plate 19 is installed at the bottom of the feeding box 2. The guide plate 19 is inclined downwards towards the center of the grate cooler body 1 at an inclination angle of 45 degrees. In specific implementation, the 30-degree inclination angle of the vibrating plate 13 ensures that the clinker is properly dispersed and buffered when falling, and also facilitates the smooth sliding of the clinker along the vibrating plate 13 to the next stage. The protrusions 14 installed on the upper surface of the vibrating plate 13 increase the contact area between the clinker and the vibrating plate 13, thereby improving heat exchange efficiency. Simultaneously, the protrusions 14 can also break and disperse the clinker to a certain extent, further improving the cooling effect. The 45-degree inclination of the guide plate 19 ensures that the clinker can smoothly slide down along the guide plate 19 to the further cooling area of ​​the grate cooler body 1. The design of the guide plate 19 not only facilitates the smooth sliding of the clinker but also guides and disperses the clinker to a certain extent, preventing the clinker from accumulating or clogging during its descent.

[0027] See Figure 3 As shown, a high-temperature recovery grate cooling device for clinker includes a conveying grate bed 5 installed at the bottom of the main body 1 of the grate cooler. A corrugated grate plate 9 is positioned above the conveying grate bed 5. The longitudinal section of the corrugated grate plate 9 consists of wavy striped protrusions, with each wavy stripe protrusion arranged in an alternating pattern. Several second fans 10 are installed on the inner wall of the main body 1 of the grate cooler, located above the concave surface of the corrugated grate plate 9. In practical implementation, the design of the corrugated grate plate 9 helps increase the contact area between the clinker and the cooling air, increasing the friction between the clinker and the corrugated grate plate 9, allowing the clinker to slide evenly on the corrugated grate plate 9, thus improving cooling efficiency. The second fans 10 blow cooling air onto the concave surface of the corrugated grate plate 9, forming forced convection, ensuring uniform distribution of the clinker under the action of the cooling air, and accelerating the cooling process of the clinker.

[0028] See Figure 2 As shown, the main body 1 of the grate cooler is hinged to a door 6 on the other side wall of the air box 3. The door 6 is equipped with a handle 7. A discharge hopper 8 is installed at one end of the main body 1, below the door 6 and the conveying grate bed 5. In the specific implementation process, after the clinker enters the main body 1 of the grate cooler, it is evenly distributed on the conveying grate bed 5 and cooled by the second fan 10. After the clinker has cooled, the operator only needs to pull the handle 7 to open the door 6 and then start the conveying grate bed 5. The clinker located above the corrugated grate plate 9 will be discharged from the discharge hopper 8.

[0029] Working principle:

[0030] Step 1: The clinker first enters the main body 1 of the grate cooler through the feeding box 2. Inside the feeding box 2, a buffer cooling mechanism is set up, which consists of several vibrating plates 13. These vibrating plates 13 are hinged to the inner wall of the feeding box 2 and tilted downwards towards the center of the feeding box 2. When the clinker falls on the vibrating plates 13, due to the tilting design of the vibrating plates 13 and the buffering effect of the spring 12 below, the clinker will be dispersed and initially cooled. At the same time, the vibration of the vibrating plates 13 and the spring 12 further promotes the cooling effect. After the first fan 4 is started, cooling air is supplied to the upper horizontal pipe 15 and the lower horizontal pipe 16 through the air box 3. This cooling air flows out through the circular through hole 18 on the vertical pipe 17 and enters the feeding box 2 to further cool the clinker. During the flow of the cooling air, not only does it carry away the heat in the clinker, but also achieves uniform distribution and efficient utilization of the cooling air through the design of the vertical pipe 17 and the circular through hole 18.

[0031] Step 2: After initial cooling, the clinker continues to fall and eventually lands on the corrugated grate 9 above the conveying grate bed 5. The design of the corrugated grate 9 increases the contact area between the clinker and the cooling air and improves the uniformity of the clinker's sliding on the grate. At the same time, the second fan 10 located above the concave surface of the corrugated grate 9 blows cooling air onto the grate, forming forced convection. This forced convection accelerates the cooling process of the clinker and ensures the uniform distribution of the clinker during the cooling process. After cooling, the clinker continues to move forward under the conveying action of the conveying grate bed 5. When the clinker reaches one end of the main body 1 of the grate cooler, it will be discharged through the discharge hopper 8 for further processing.
