Description

Technical Field

[0001] This invention belongs to the field of kiln technology, specifically relating to cooling, and more particularly to a heat dissipation structure for a grate cooler, the grate cooler, and its operating method. Background Technology

[0002] To improve the cooling rate of cement clinker, several heat dissipation structures are installed at the bottom of the feeding ramp of the grate cooler. In related technologies, to facilitate the adjustment of air volume, the heat dissipation structure is configured with air inlets on the bottom and one of the side walls, and a sliding plate is installed at the bottom of the air vent to manually adjust and change the effective opening area of ​​the air vent, thereby changing the air volume. However, this method still has some problems. When dealing with the renovation of old grate coolers, since the air volume of the fan can no longer be increased, the existing heat dissipation structure with only three air inlets will cause insufficient air volume, resulting in insufficient heat dissipation efficiency for cement clinker.

[0003] There is an urgent need to design a heat dissipation structure, a grate cooler, and a working method for a grate cooler.

[0004] It should be noted that the information disclosed in this background section is only for understanding the background technology of the present application concept, and therefore, the above description is not considered to constitute prior art information. Summary of the Invention

[0005] This disclosure provides at least one heat dissipation structure for a grate cooler, a grate cooler, and a method for its operation. In a first aspect, embodiments of this disclosure provide a heat dissipation structure for a grate cooler, comprising: The material feeding ramp has several air inlets on its bottom surface, and each air inlet is covered with a corresponding heat dissipation mechanism, which is configured to adjust the air intake of the air inlet. The heat dissipation mechanism includes: a bottom cover; The bottom cover is installed outside the corresponding air inlet; The bottom cover has a pair of first strip holes arranged horizontally side by side on one pair of side walls, and a second strip hole arranged on the other pair of side walls. The bottom surface of the bottom cover has a pair of first through holes; A pair of adjustment components are slidably disposed on the outer wall of the bottom cover; When the two adjustment components move away from each other, the exposed portions of the first strip hole and the first through hole increase, while the blocked portion of the second strip hole decreases. Gas enters the area covered by the bottom cover through the first strip hole, the second strip hole, and the first through hole, and flows towards the air inlet to increase the air intake volume of the air inlet.

[0006] In one optional embodiment, the adjustment assembly includes: an adjustment element; The adjusting member is disposed outside the bottom cover, and the top surface and one side wall of the adjusting member are open to partially surround the bottom cover; The sidewalls opposite the opening of the adjusting component correspond to the second strip hole, and the remaining pair of sidewalls correspond to one strip hole on the sidewall of the bottom cover; The bottom surface of the adjusting member corresponds to the first through hole.

[0007] In one optional embodiment, the cross-section of the second strip hole is trapezoidal; A plug is provided on the side wall opposite the opening of the adjusting member, which is adapted to the second strip hole. The plug is inserted into the corresponding second strip hole, and when the plug is inserted to its limit position, the outer wall of the plug contacts the inner wall of the second strip hole to seal the second strip hole.

[0008] In one optional embodiment, the bottom cover has a plurality of second through holes equidistantly spaced along the length of the second strip hole above the second strip hole; The inner wall of the adjusting member is rotatably connected to a column corresponding to the second through hole, that is, one end of the column is rotatably connected to the inner wall of the adjusting member, and the column passes through the corresponding second through hole; The outer wall of the column is provided with a spiral groove, and the inner wall of the second through hole is provided with a protrusion, which is inserted into the spiral groove; A baffle is obliquely provided at the other end of the column, and ventilation holes are provided on the baffle.

[0009] In one alternative embodiment, as the two adjusting members move away from their closest position, the first strip hole and the first through hole, which were previously completely blocked, gradually become exposed. The plug gradually moves out of the second strip hole, and a gap is formed between the plug and the second strip hole. Gas enters the area covered by the bottom cover through the exposed portions of the first strip hole and the first through hole, as well as the gap between the plug and the second strip hole.

[0010] In one alternative implementation, when the two adjusting members move away from their closest position, they drive the column to move. The protrusion moves along the spiral groove, causing the column to rotate. When the adjusting member drives the baffle to rotate to an upward tilting state, the gas enters the area covered by the bottom cover and is guided by the baffle, causing the gas to flow upward.

[0011] In one alternative implementation, when the two adjusting members move away from their closest position, they cause the column to move. The protrusion moves along the spiral groove, causing the column to rotate. When the adjusting member causes the baffle to rotate to a downward tilting position, the gas flows upward through the ventilation hole.

[0012] Secondly, embodiments of this disclosure also provide a grate cooler, comprising: The above-mentioned heat dissipation structure is used for grate coolers.

[0013] Thirdly, embodiments of this disclosure also provide a method for operating the heat dissipation structure described above for a grate cooler, comprising: When the two adjustment components move away from each other, the exposed portions of the first strip hole and the first through hole increase, while the blocked portion of the second strip hole decreases. Gas enters the area covered by the bottom cover through the first strip hole, the second strip hole, and the first through hole, and flows towards the air inlet to increase the air intake volume of the air inlet.

[0014] In one alternative embodiment, as the two adjusting members move away from their closest position, the first strip hole and the first through hole, which were previously completely blocked, gradually become exposed. The plug gradually moves out of the second strip hole, and a gap is formed between the plug and the second strip hole. Gas enters the area covered by the bottom cover through the exposed portions of the first strip hole and the first through hole, as well as the gap between the plug and the second strip hole.

[0015] The beneficial effect of this invention is that, in order to improve the heat dissipation structure for a grate cooler, when the two adjusting components are far apart, the exposed portions of the first strip hole and the first through hole increase, while the blocked portion of the second strip hole decreases. Gas enters the area covered by the bottom cover through the first strip hole, the second strip hole, and the first through hole, and flows towards the air inlet, thereby increasing the air intake volume of the air inlet. This allows all five sides of the bottom cover to be used for air intake, thus improving the heat dissipation effect.

Therefore, a particular feature, structure, or characteristic can be included in more than one embodiment of this disclosure, such that these phrases do not necessarily refer to the same embodiment.

[0023] To improve the cooling rate of cement clinker, several heat dissipation structures are installed at the bottom of the feeding ramp of the grate cooler. In related technologies, to facilitate the adjustment of air volume, the heat dissipation structure is configured with air inlets on the bottom and one set of side walls. A sliding plate is installed at the bottom of the heat dissipation structure so that the effective area of ​​the air inlet can be adjusted by moving the sliding plate, thereby changing the air volume. However, this method still has some problems. When dealing with the renovation of old grate coolers, since the air volume of the fan can no longer be increased, even if the effective area of ​​the air inlet is adjusted to the maximum, the air volume will still be insufficient, resulting in insufficient heat dissipation efficiency for cement clinker.

[0024] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0025] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0026] like Figure 1 , Figure 2 and Figure 3 As shown, at least one other disclosed embodiment provides a heat dissipation structure for a grate cooler, including: a feeding ramp 1, the bottom surface of which is provided with a plurality of air inlets (not shown in the figure due to obstruction), each air inlet being covered with a corresponding heat dissipation mechanism 2 configured to adjust the air intake of the air inlets; the heat dissipation mechanism 2 includes: a bottom cover 21; the bottom cover 21 is covered outside the corresponding air inlets; a pair of first strip-shaped holes 211 are horizontally arranged side by side on a pair of side walls of the bottom cover 21, and a second strip-shaped hole 212 is opened on the other pair of side walls. The bottom surface of the bottom cover 21 is provided with a pair of first through holes 213; a pair of adjustment components 22 are slidably arranged on the outer wall of the bottom cover 21; when the two adjustment components 22 move away from each other, the exposed part of the first strip hole 211 and the first through hole 213 increases, and the blocked part of the second strip hole 212 decreases. Gas enters the area covered by the bottom cover 21 through the first strip hole 211, the second strip hole 212 and the first through hole 213 and flows to the air inlet to increase the air intake volume of the air inlet. Thus, all five sides of the bottom cover 21 can be used for air intake, improving the heat dissipation effect.

[0027] In this embodiment, gas can be blown through the air inlet to the top surface of the feeding ramp 1 to dissipate heat from the clinker on the top surface of the feeding ramp 1.

[0028] In this embodiment, without changing the original installation position of the bottom cover 21, air can enter from all five sides of the bottom cover 21, increasing the air flow and improving the heat dissipation effect.

[0029] In this embodiment, a fan can be installed below the bottom cover 21 to generate airflow.

[0030] like Figure 4 As shown, in an optional embodiment, the adjustment assembly 22 includes: an adjustment member 221; the adjustment member 221 is disposed outside the bottom cover 21, and the top surface and one side wall of the adjustment member 221 are open to partially surround the bottom cover 21; the side wall opposite to the opening of the adjustment member 221 corresponds to the second strip hole 212, and the remaining pair of side walls correspond to a strip hole on the side wall of the bottom cover 21; the bottom surface of the adjustment member 221 corresponds to the first through hole 213.

[0031] In this embodiment, the inner wall of the adjusting member 221 can contact the side wall of the bottom cover 21 to completely block the first strip hole 211.

[0032] In this embodiment, a strip groove corresponding to the moving direction of the adjusting member 221 can be provided on the side wall of the bottom cover 21. The strip groove is located on the side wall of the bottom cover 21 where the first strip hole 211 is provided. A slider corresponding to the strip groove can be provided on the inner wall of the adjusting member 221. The slider extends into the corresponding strip groove. The cooperation between the slider and the strip groove can prevent the adjusting member 221 from falling off, and guide and limit the moving direction of the adjusting member 221 when it moves.

[0033] In this embodiment, the adjusting member 221 can completely block the corresponding first strip hole 211 and first through hole 213.

[0034] like Figure 3 and Figure 4 As shown, in one optional embodiment, the cross-section of the second strip hole 212 is trapezoidal; a blocking strip 222 adapted to the second strip hole 212 is provided on the side wall opposite to the opening of the adjusting member 221. The blocking strip 222 is inserted into the corresponding second strip hole 212, and when the blocking strip 222 is inserted to its limit position, the outer wall of the blocking strip 222 contacts the inner wall of the second strip hole 212 to seal the second strip hole 212.

[0035] In this embodiment, the blocking strip 222 can block the second strip hole 212, preventing gas from entering the area surrounded by the bottom cover 21 through the second strip hole 212.

[0036] like Figure 3 and Figure 4 As shown, in one optional embodiment, the bottom cover 21 has a plurality of second through holes 214 equidistantly spaced above the second strip hole 212 along the length of the second strip hole 212; the inner wall of the adjusting member 221 is rotatably connected to a column 223 corresponding to the second through hole 214, that is, one end of the column 223 is rotatably connected to the inner wall of the adjusting member 221, and the column 223 passes through the corresponding second through hole 214; a spiral groove 225 is provided on the outer wall of the column 223, and a protrusion (not shown in the figure due to obstruction) is provided on the inner wall of the second through hole 214, the protrusion being inserted into the spiral groove 225; a baffle 224 is obliquely provided on the other end of the column 223, and a ventilation hole 215 is provided on the baffle 224.

[0037] In this embodiment, when the two adjusting members 221 are in the closest possible position, the first strip hole 211 is completely blocked by the side wall of the adjusting member 221, the first through hole 213 is blocked by the bottom surface of the adjusting member 221, the blocking strip 222 is inserted into the second strip hole 212, and the outer wall of the blocking strip 222 contacts the inner wall of the second strip hole 212 to block the second strip hole 212, thereby preventing airflow from entering the heat dissipation mechanism 2. At this time, the baffle 224 is in an approximately upward tilted state so that when the two adjusting members 221 begin to move away from each other, the baffle 224 can be rotated to the upward tilted state. When the air intake volume of the air inlet needs to be increased, the two adjusting members 221 move away from each other. As the strip hole 211 and the first through hole 213 gradually become exposed, and the exposed portion gradually increases, the plug 222 moves out of the second strip hole 212, and the gap between the plug 222 and the second strip hole 212 forms an air intake channel, allowing gas to flow into the heat dissipation mechanism 2 through the air intake channel and the second strip hole 212. When the two adjusting members 221 move to their farthest distance, the first strip hole 211 and the first through hole 213 are fully exposed, and the gap between the plug 222 and the second strip hole 212 is at its maximum. At the same time, as the two adjusting members 221 move away from each other, the protrusion moves along the spiral groove 225, causing the column 223 to rotate, and the baffle 224 rotates from an upward tilting state to a downward tilting state.

[0038] Specifically, when the two adjusting members 221 drive the baffle 224 to rotate to an upward tilted state, the gas is guided upward. When the adjusting members 221 drive the baffle 224 to rotate to a downward tilted state, the gas can flow upward through the ventilation hole 215. The reason for this setting is that when the adjusting members 221 move the maximum distance, the air intake in the heat dissipation mechanism 2 is the maximum. At this time, the lateral horizontal air intake will impact the upward airflow in the first through hole 213. Therefore, the baffle 224 is rotated to a downward tilted state to block the lateral airflow, so that the airflow can only flow upward through the ventilation hole 215, thereby ensuring the stability of the gas flow direction.

[0039] In this embodiment, the distance that the two adjusting members 221 need to move to the first time when the stop bar 224 is rotated to the upward tilting state is shorter than the distance that the adjusting members 221 need to move to the first time when the stop bar 224 is rotated to the downward tilting state.

[0040] For details, see Figure 5 and Figure 6The baffle 224 has ventilation holes 215. When it is in the first blowing state, that is, when the baffle 224 is tilted upward, the gas blown in will flow in the F1 direction. When it is in the second blowing state, that is, when the baffle 224 is tilted downward, the gas blown in will flow in the F2 direction. At this time, the baffle 224 blocks the gas blowing directly and causes the gas to be blown out through the ventilation holes 215, thereby changing the direction of gas flow and avoiding the strong air volume blown in horizontally from disturbing the gas blown in from other directions.

[0041] As an optional implementation, the movement of the adjusting member 221 includes, but is not limited to, manual adjustment or mechanical drive adjustment. Mechanical drive adjustment can be performed in real time using hydraulic drive.

[0042] In one alternative embodiment, as the two adjusting members 221 move away from their closest position, the first strip hole 211 and the first through hole 213, which were previously completely blocked, gradually become exposed. The plug 222 gradually moves out of the second strip hole 212, forming a gap between the plug 222 and the second strip hole 212. Gas enters the area covered by the bottom cover 21 through the exposed portions of the first strip hole 211 and the first through hole 213, as well as the gap between the plug 222 and the second strip hole 212.

[0043] In one alternative embodiment, when the two adjusting members 221 move away from their closest position, they drive the column 223 to move. The protrusion moves along the spiral groove 225, causing the column 223 to rotate. When the adjusting member 221 drives the baffle 224 to rotate to an upward tilting state, the gas enters the area covered by the bottom cover 21 and is guided by the baffle 224, causing the gas to flow upward.

[0044] In one alternative embodiment, when the two adjusting members 221 move away from their closest position, they drive the column 223 to move. The protrusion moves along the spiral groove 225, causing the column 223 to rotate. When the adjusting member 221 drives the baffle 224 to rotate downward, the gas flows upward through the ventilation hole 215.

[0045] At least one other disclosed embodiment also provides a grate cooler, including: the heat dissipation structure for the grate cooler described above.

[0046] At least one other disclosed embodiment also provides a method of operation using the above-described heat dissipation structure for a grate cooler, comprising: when the two adjusting components 22 are moved away from each other, the exposed portions of the first strip hole 211 and the first through hole 213 increase, the blocked portion of the second strip hole 212 decreases, and gas enters the area covered by the bottom cover 21 through the first strip hole 211, the second strip hole 212 and the first through hole 213 and flows to the air inlet to increase the air intake volume of the air inlet.

[0047] In one alternative embodiment, as the two adjusting members 221 move away from their closest position, the first strip hole 211 and the first through hole 213, which were previously completely blocked, gradually become exposed. The plug 222 gradually moves out of the second strip hole 212, forming a gap between the plug 222 and the second strip hole 212. Gas enters the area covered by the bottom cover 21 through the exposed portions of the first strip hole 211 and the first through hole 213, as well as the gap between the plug 222 and the second strip hole 212.

[0048] In summary, the heat dissipation structure for the grate cooler increases the exposed portion of the first strip hole 211 and the first through hole 213 when the two adjusting components 22 are far apart, while reducing the blocked portion of the second strip hole 212. Gas enters the area covered by the bottom cover 21 through the first strip hole 211, the second strip hole 212, and the first through hole 213 and flows towards the air inlet, thereby increasing the air intake volume of the air inlet. This allows all five sides of the bottom cover 21 to be used for air intake, improving the heat dissipation effect.
