Description

Technical Field

[0001] This utility model relates to the field of grate cooler technology, specifically to an anti-caking auxiliary pushing device for grate coolers. Background Technology

[0002] A grate cooler, also known as a grate-type cooler, is primarily used for cooling and conveying cement clinker, while also providing hot air to rotary kilns and preheating furnaces. It is a key piece of equipment for heat recovery in calcination systems. Grate coolers offer many advantages as cooling devices, including high cooling efficiency, high heat recovery efficiency, long service life, and easy maintenance. Therefore, they are widely used in the production industries of cement, silicate products, new building materials, refractory materials, and glass ceramics.

[0003] Clinker caking may occur during the operation of a grate cooler. This caking can be caused by various factors, including the high temperature and dispersibility of the clinker, unburned coal dust being trapped in the clinker, poor air permeability of the grate cooler, and insufficient cooling air pressure. Clinker caking reduces the processing capacity of the grate cooler, thus affecting the overall production line efficiency. Therefore, we need auxiliary equipment to assist the grate cooler in preventing clinker caking during the cooling process. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides an anti-caking auxiliary pushing device for a grate cooler to prevent clinker from caking during the cooling process.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an anti-caking auxiliary pushing device for a grate cooler, comprising a grate bed, an auxiliary pushing component disposed on the grate bed, the auxiliary pushing component comprising a pushing frame disposed around the movable grate bed, a hydraulic rod disposed on the bottom surface of the pushing frame, and a pushing base disposed under the hydraulic rod, the bottom surface of the pushing base being provided with a plurality of anti-caking pushing components, the anti-caking pushing components being evenly and uniformly disposed along a W-shape, and the anti-caking pushing components corresponding one-to-one with the position of the grate bed.

[0006] Furthermore, the anti-caking pushing assembly includes a fixed plate disposed on the bottom surface of the pushing base and a rotating plate rotatably connected to the bottom surface of the fixed plate, with a material pass-through comb opening at the lower end of the rotating plate.

[0007] Furthermore, a rotating fixing block is provided in the middle of one side of the fixing plate, and a rotating gear is provided on the outside of the rotating fixing block. The rotating gear is rotatably connected to the driving block located above the rotating gear through a driving belt. A driving motor is connected to the rear end of the driving block. The driving motor and the driving block are set in the push base. The push base has a driving groove for the rotation of the driving belt and the driving block.

[0008] Furthermore, the rotating fixing blocks are symmetrically arranged on both sides of the fixing plate and are fixedly connected by the rotating connecting block set in the middle of the fixing plate.

[0009] Furthermore, a position sensor is installed on one side of the drive slot of the base.

[0010] Furthermore, a temperature sensor is installed on the bottom surface of the base.

[0011] Furthermore, three temperature sensors are provided, located at the front, middle, and rear ends of the bottom surface of the push base.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] By installing anti-caking pushing components at corresponding positions on the grate, the rotating plate of the anti-caking pushing components moves along with the moving grate as it reciprocates, causing the clinker to tumble and thus preventing clinker caking and improving the cooling efficiency of the clinker. Furthermore, by installing a rotating fixed block and a rotating gear on the outside of the rotating fixed block, when the rotating plate is in the correct position, the drive motor, drive block, and drive belt drive the rotating fixed block to rotate, thereby fixing the rotating plate. This allows the rotating plate to better push the clinker, enabling it to move quickly on the moving grate and further improving cooling efficiency. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] like Figures 1 to 5 As shown, an anti-caking auxiliary pushing device for a grate cooler includes a grate bed 1, an auxiliary pushing component 2 on the grate bed 1, and the auxiliary pushing component 2 includes a pushing frame 201 arranged around the movable grate bed 1, a hydraulic rod 202 arranged on the bottom surface of the pushing frame 201, and a pushing base 203 arranged under the hydraulic rod 202. A plurality of anti-caking pushing components 3 are arranged on the bottom surface of the pushing base 203. The anti-caking pushing components 3 are evenly arranged in a W-shape with staggered positions, and the positions of the anti-caking pushing components 3 correspond one-to-one with the grate bed 1.

[0022] like Figure 1 As shown, the main improvement of this utility model lies in preventing clinker from caking during the cooling process in the grate cooler, such as... Figures 1 to 5 As shown, the anti-caking auxiliary pushing device for a grate cooler of this utility model, in use, first uses the hydraulic rod 202 to press down the pushing base 203 and the anti-caking pushing component 3, so that the rotating plate 302 can fit against the bottom surface of the compartment in the grate bed 1, completing the alignment of the rotating plate 302; then the grate cooler is started, and the grate bed 1 begins to move. At this time, the drive motor 308 will drive the rotating gear 305 to rotate by the linkage of the rotating gear 305, the drive belt 306 and the drive block 307, so that the long end of the rotating fixed block 303 faces downward, and the rotating gear 305 rotates downward. Once plate 302 is fixed in place, the fixed rotating plate 302 can better push the clinker, allowing the clinker to be quickly turned over on the grate 1, thus improving cooling efficiency. As the grate 1 moves, when the rotating plate 302 is about to reach the other end of the compartment, the drive motor 308 will drive the rotating fixed block 303 back to its original position. The rotating plate 302 can then rotate and move with the grate 1, falling into the next compartment. This process repeats to turn the clinker over and prevent clinker from caking during the cooling process.

[0023] like Figure 4 and Figure 5 As shown, the anti-caking push assembly 3 includes a fixed plate 301 disposed on the bottom surface of the push base 203 and a rotating plate 302 rotatably connected to the bottom surface of the fixed plate 301. The lower end of the rotating plate 302 is provided with a material pass-through comb 304.

[0024] Specifically, by setting a fixed plate 301 on the bottom surface of the push base 203, and rotatably connecting a rotating plate 302 to the bottom surface of the fixed plate 301, when facing the clinker on the grate 1, the rotating plate 302 also moves left and right on the grate 1 as the grate 1 moves, causing the clinker on the grate 1 to flip, thereby avoiding clinker caking and improving the cooling efficiency of the clinker; at the same time, the rotation of the rotating plate 302 also prevents the rotating plate 302 from hitting the fasteners on the grate 1 and being damaged when pushing the clinker, and the setting of the material comb 304 allows some clinker to pass through it when pushing, further flipping the clinker.

[0025] like Figure 4 and Figure 5 As shown, a rotating fixing block 303 is provided in the middle of one side of the fixing plate 301, and a rotating gear 305 is provided on the outside of the rotating fixing block 303. The rotating gear 305 is rotatably connected to the driving block 307 located above the rotating gear 305 through the driving belt 306. The rear end of the driving block 307 is connected to the driving motor 308. The driving motor 308 and the driving block 307 are arranged in the push base 203. The push base 203 has a driving groove 204 for the rotation of the driving belt 306 and the driving block 307.

[0026] like Figure 5 As shown, the rotating fixing blocks 303 are symmetrically arranged on both sides of the fixing plate 301 and are fixedly connected by the rotating connecting block 309 arranged in the middle of the fixing plate 301.

[0027] Specifically, with the cooperation of the rotating gear 305, drive belt 306, drive block 307, and drive motor 308, when the rotating plate 302 is in the correct position, such as when the rotating plate 302 has just fallen into the compartment on the grate bed 1, the drive motor 308 will drive the rotating gear 305 to rotate, thereby causing the rotating fixing block 303 to rotate downwards and fix the rotating plate 302. The fixed rotating plate 302 can better push the clinker, so that the clinker can be quickly turned over on the grate bed 1, and the cooling efficiency is also improved. When the rotating plate 302 is about to reach the other end of the compartment, the drive motor 308 will drive the rotating fixing block 303 back to its original position. The rotating plate 302 can rotate and fall into the next compartment as the grate bed 1 moves, thus repeating the above steps.

[0028] like Figure 2 and Figure 3 As shown, a position sensor 4 is provided on one side of the drive slot 204 of the push base 203.

[0029] like Figure 2 and Figure 3 As shown, a temperature sensor 5 is provided on the bottom surface of the push base 203. There are three temperature sensors 5, which are respectively located at the front end, middle end and rear end of the bottom surface of the push base 203.

[0030] Specifically, by setting a position sensor 4 on the bottom surface of the push base 203, the position of the rotating plate 302 during the material pushing process can be monitored in real time, helping the staff to detect problems in time. The temperature sensor 5 on the push base 203 can provide the staff with real-time temperature information. The temperature sensors 5 are set at the front, middle and rear ends, and the data transmitted by each temperature sensor 5 can be compared to help the staff observe the cooling situation and react in time.

[0031] 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 make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
