Description

Technical Field

[0001] This utility model relates to the field of grate cooler technology, specifically a high-efficiency hot air drying grate cooler. Background Technology

[0002] A grate cooler is a type of rapid cooling cooler. After the clinker enters the cooler from the kiln, it is laid in a layer of a certain thickness on the grate. Cold air is blown in and passes through the moving material layer on the grate in a direction perpendicular to each other, so that the clinker is rapidly cooled. It can cool the clinker from 1300-1400℃ to below 100℃ in a few minutes. At the same time, the hot air after heat exchange is recovered and reused, for example, sent back to the kiln or used to dry the material.

[0003] The existing Chinese utility model patent with publication number CN217929821U discloses a high-efficiency hot air recovery device for a grate cooler used in cement production. It includes a stepped hood positioned above the grate cooler body. From left to right, the stepped hood has a large-diameter air intake, a waste heat power generation air intake, and a tail exhaust port. It also includes a flow stabilizing tank. The large-diameter air intake is connected to the side wall of the flow stabilizing tank via a first air supply pipe. The waste heat power generation air intake is connected to the bottom of the flow stabilizing tank via a second air supply pipe. The tail exhaust port is connected to the side wall of the flow stabilizing tank via a third air supply pipe. An annular flow stabilizing fluid is also provided inside the flow stabilizing tank, with the openings of the second and third air supply pipes facing the annular flow stabilizing fluid. This device can maintain the high-efficiency and stable operation of the heat recovery equipment, improve recovery efficiency, and achieve energy saving.

[0004] Although the aforementioned high-efficiency hot air recovery device for a grate cooler used in cement production can effectively recover the hot air at the kiln head by setting up a stepped hood and a large-diameter air intake, the existing grate cooler has poor hot air recovery and drying effect, is inconvenient to operate, and has low efficiency. Utility Model Content

[0012] In a preferred embodiment, a top cover is fixedly installed on the top of one side of the side plate, and telescopic columns are fixedly installed inside the bottom two sides of the top cover. The telescopic columns are structures for telescopic movement.

[0013] In a preferred embodiment, an insertion plate is fixedly installed at the bottom of the telescopic column, and an extraction pump is fixedly installed at the top center of the top cover. The extraction pump is a structure used to extract moisture.

[0014] In a preferred embodiment, a suction hood is fixedly installed at the bottom of the extraction pump, and an exhaust pipe is fixedly installed at the top of the extraction pump. The exhaust pipe is a structure used for exhausting gas.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This high-efficiency hot air drying grate cooler uses an air pump to extract high-temperature flue gas and send it through a conveying pipe into the filter device.

[0017] 2. This high-efficiency hot air drying grate cooler features an adjustable base plate height via lifting legs, facilitating the placement of different conveyor belts. The telescopic rods extend and retract, pushing the lifting plate upwards to seal one side. The telescopic columns on both sides of the top cover extend and retract, pushing the insertion plate downwards to shield both sides. This design enhances the convenience and practicality of the high-efficiency hot air drying grate cooler, thereby increasing its efficiency. Attached Figure Description

[0024] 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.

[0025] Combined with appendix Figure 1-5In this embodiment, a high-efficiency hot air drying grate cooler includes: a cross valve 1, which is shaped like a cross; two switch valves 11 are fixedly installed on both sides of the cross valve 1; two air outlet blocks 12 are fixedly installed on both sides of the cross valve 1; an air outlet rod 13 is fixedly installed on the top of the air outlet block 12; an air outlet 14 is fixedly installed on one side of the air outlet rod 13; an air outlet plate 15 is fixedly installed on the top of the cross valve 1; and a nozzle 16 is fixedly installed on the top of the air outlet plate 15.

[0026] Specifically, the two sides can be opened or closed by the switch valves 11 on both sides of the cross valve 1, the flue gas can be sent into the interior of the air outlet 13 by the air outlet block 12, and the high temperature gas can be blown onto the material at the top of the conveyor belt 22 for drying by the air outlet 14 on one side of the air outlet 13.

[0027] A base plate 2 is fixedly installed at the bottom of the air outlet plate 15. Four lifting legs 21 are fixedly installed around the bottom of the base plate 2. A conveyor belt 22 is movably connected to the top of the base plate 2. Two side plates 23 are fixedly installed on both sides of the top of the base plate 2. Two telescopic rods 24 are fixedly installed inside one side of the side plate 23. A lifting plate 25 is fixedly installed on the top of the telescopic rods 24.

[0028] Specifically, by raising and lowering the lifting leg 21, the conveyor belt 22 can be wrapped inside the high-efficiency hot air drying grate cooler. By extending and retracting the telescopic rod 24, the lifting plate 25 can be pushed upward, thereby sealing one side and providing support through the other side plate 23.

[0029] A gas outlet hose 3 is fixedly installed at the bottom of the cross valve 1. A filter device 31 is fixedly installed on one side of the gas outlet hose 3. A conveying pipe 32 is fixedly installed on one side of the filter device 31. An air pump 33 is fixedly installed on one side of the conveying pipe 32. A grate cooler body 34 is fixedly installed at the bottom of the air pump 33.

[0030] Specifically, the high-temperature flue gas inside the grate cooler body 34 can be extracted by the operation of the air pump 33 and sent into the filter device 31 through the delivery pipe 32. The filter device 31 can filter the flue gas, and finally the high-temperature gas is sent into the cross valve 1 through the exhaust hose 3.

[0031] A top cover 4 is fixedly installed on the top of one side of the side plate 23. Telescopic columns 41 are fixedly installed inside the bottom two sides of the top cover 4. An insertion plate 42 is fixedly installed at the bottom of the telescopic columns 41. A suction pump 43 is fixedly installed in the middle of the top of the top cover 4. A suction hood 44 is fixedly installed at the bottom of the suction pump 43. An exhaust pipe 45 is fixedly installed at the top of the suction pump 43.

[0032] Specifically, the top cover 4 can support the extraction pump 43. The operation of the extraction pump 43 can extract moisture through the extraction hood 44 and discharge it through the exhaust pipe 45. The extension and retraction of the telescopic columns 41 on both sides of the bottom of the top cover 4 can push the insertion plate 42 to move downward, thereby blocking the sides.

[0033] Working Principle: First, the high-efficiency hot air drying grate cooler is placed in the designated position. The retraction of the lifting legs 21 allows the base plate 2 to move downwards. The conveyor belt 22 is then moved to the top of the base plate 2. The extension and retraction of the lifting legs 21 pushes the base plate 2 upwards, thus wrapping the conveyor belts 22 and improving the convenience and drying efficiency of the high-efficiency hot air drying grate cooler. The extension and retraction of the telescopic rods 24 inside the side plates 23 pushes the lifting plate 25 upwards, sealing one side. The other side plate 23 supports the top cover 4. The extension and retraction of the telescopic columns 41 inside the bottom of the top cover 4 pushes the insertion plate 42 downwards, shielding the other two sides. This improves the practicality and convenience of the high-efficiency hot air drying grate cooler and prevents hot air leakage from affecting the drying process. To address the drying effect, the operation of the air pump 33 extracts the flue gas from inside the main body 34 of the grate cooler and sends it through the conveying pipe 32 into the filter device 31. The filter device 31 filters the flue gas, which is then sent through the exhaust hose 3 into the cross valve 1. The cross valve 1 sends the flue gas into the two exhaust blocks 12, which then spray the flue gas out through the exhaust port 14 on one side of the exhaust rod 13. The exhaust plate 15 sprays the flue gas out through the nozzle 16, thus uniformly drying the material on top of the conveyor belt 22 and improving the drying efficiency of this high-efficiency hot air drying grate cooler. The two cross valves 1 can be opened and closed by the switch valve 11. The operation of the extraction pump 43 absorbs moisture through the extraction hood 44 and discharges moisture through the exhaust pipe 45, improving the practicality of this high-efficiency hot air drying grate cooler.

[0034] 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.
