[0033] Example: Please refer to Figures 1-6In this embodiment of the invention, an intelligent automatic slag collection device for coal mill stones includes a conveying pipe 1, a cooling mechanism 2, and a collection trolley 3. The cooling mechanism 2 is fixedly arranged between the conveying pipes 1, dividing the conveying pipes 1 into an upper conveying pipe and a lower conveying pipe. The lower conveying pipe has a collection port 4 at its output end. The collection trolley 3 is arranged below the collection port 4, and a lifting platform 5 is arranged below the collection trolley 3. The lifting platform 5 can lift the collection trolley 3 upward, so that the collection trolley 3 fits tightly against the collection port 4.

[0034] The cooling mechanism 2 is a cavity with openings at both the top and bottom. The cavity is divided into two independent cavities by a baffle 24, namely a cooling cavity 25 and a filter cavity 26. The baffle 24 is provided with a through hole 241, which can connect the cooling cavity 25 and the filter cavity 26.

[0035] The cooling chamber 25 can cool and remove dust from the coal stones by using water mist, and the filtration chamber 26 can filter out the moisture in the cooled coal stones.

[0036] In practice, the coal stones from the coal mill are transported to the cooling mechanism 2 through the conveying pipe 1. The cooling chamber 25 cools and removes dust from the coal stones, and the filtering chamber 26 filters out the moisture. After filtration, the coal stones are transported to the collection port 4 through the lower conveying pipe. The lifting platform 5 uses the collection trolley 3 to collect the coal stones from below the collection port 4. When the collection trolley 3 finishes collecting, the next collection trolley 3 is replaced, and this cycle continues until all the coal stones are collected.

[0037] In this embodiment, as Figure 3 The cooling mechanism 2 also includes a housing 21, a top plate 22, and a bottom plate 23, wherein the top plate 22, the housing 21, and the baffle 24 together form a cooling chamber 25, and the bottom plate 23, the housing 21, and the baffle 24 together form a filter chamber 26.

[0038] In this embodiment, as Figure 2 , 3 The top plate 22 is provided with an inlet 221, which is connected to the upper conveying pipe;

[0039] A partition 27 is rotatably disposed in the cooling chamber 25;

[0040] The partition 27 includes a ring seat 271 and a plate 272, wherein a plurality of plates 272 are arranged in a circular array on the ring seat 271, and the plurality of plates 272 divide the cooling cavity 25 into a plurality of small compartments.

[0041] A second partition 28, which has the same structure as the first partition 27, is rotatably disposed in the filter chamber 26.

[0042] The bottom plate 23 has a discharge port 234, which is connected to the lower conveying pipe.

[0043] Please see Figure 2 , 3 The gravel enters the cooling chamber 25 through the feed inlet 221. The first baffle 27 rotates counterclockwise, pushing the gravel to slide in the cooling chamber 25. During this process, the water spray nozzle 222 sprays water to cool and remove dust from the gravel inside the cooling chamber 25. When the first baffle 27 rotates to the through hole 241, the gravel enters the filter chamber 26 through the through hole 241. The second baffle 28 rotates clockwise, pushing the gravel to slide in the filter chamber 26. During the sliding process, the water generated during the cooling of the gravel is filtered by the filter hole 231 onto the water collection plate 232 and discharged through the drain pipe. When the second baffle 28 rotates to the discharge port 234, the gravel enters the lower conveying pipe through the discharge port 234 and is transported to the collection trolley 3 through the collection port 4.

[0044] Furthermore, the first partition 27 rotates clockwise and the second partition 28 rotates counterclockwise, allowing the gravel to slide around the cooling chamber 25 and the filter chamber 26 once, increasing the time the gravel spends in the cooling mechanism 2 and improving its cooling and filtration effects.

[0045] In addition, the cooling mechanism 2 can also be used as a gate. When the first partition 27 and the second partition 28 stop rotating, the stones and coal cannot be transported through the cooling mechanism 2.

[0046] In this embodiment, as Figure 5 , 6 The height of the plate 272 is three-quarters of the height of the ring seat 271;

[0047] Furthermore, a notch is provided at the top of the plate 272, and a deflection plate 273 is rotatably disposed inside the notch;

[0048] The ring seat 271 has a deflection cavity 2711. The deflection plate 273 is rotatably disposed in the deflection cavity 2711 via a rotating shaft 2731. Deflection rods 2732 are fixedly disposed at both ends of the rotating shaft 2731. The deflection rods 2732 are connected to the deflection cavity 2711 by a spring.

[0049] A pusher plate 225 is fixedly installed on the top plate 22 at the inlet 221. The pusher plate 225 can push the deflection plate 273 located in the cooling chamber 25 to deflect it.

[0050] A pusher plate 242 is fixedly installed on the baffle 24 at the through hole 241. The pusher plate 242 can push the deflection plate 273 located in the filter cavity 26 to deflect it.

[0051] During implementation, after the partition 27 rotates to the feed inlet 221, the stones and coal in the conveying pipe 1 will be transferred to the small compartment formed by the two adjacent partitions 27. When the height of the stones and coal in the small compartment exceeds the plate 272, it can slide from the side of the plate 272 to the next compartment. When the partition 27 rotates, the push plate 225 can further push the stones and coal in the small compartment, so that the stones and coal exceeding the height of the partition 272 are pushed to the next compartment, preventing jamming due to excessive stones and coal. During this process, the deflection plate 273 can deflect, making it easier for the stones and coal to slide to the next small compartment. After the deflection plate 273 rotates past the push plate 225, it can be reset under the action of the spring.

[0052] In addition, limiting the height of the stones and coal in the small chamber to three-quarters can further improve the cooling efficiency of the cooling chamber and prevent insufficient cooling caused by excessive stones and coal in the small chamber.

[0053] In this embodiment, as Figure 3 The top plate 22 is also fixedly provided with a plurality of water spray nozzles 222 corresponding to the position of the small compartment, and the plurality of water spray nozzles 222 are connected to the outside through water spray pipes 223;

[0054] The top plate 22 is also equipped with a steam pipe 224, which can discharge the steam generated when the stone coal is cooled.

[0055] In this embodiment, as Figure 2 The base plate 23 has multiple filter holes 231, and a water collection plate 232 is inclinedly arranged below the filter holes 231. The water collection plate 232 is arc-shaped, and its lowest end is connected to the outside through a drain pipe 233.

[0056] In this embodiment, as Figure 2 The inlet 221 and the outlet 234 are in the same position, and there is a small compartment space between the through hole 241 and the inlet 221 and the outlet 234.

[0057] It should be noted that the small gap between the through hole 241 and the inlet 221 and outlet 234 can effectively prevent the stones and coal from entering through the inlet 221 and sliding directly through the through hole 241 to the outlet 234, thus preventing some of the stones and coal from being cooled.

[0058] In this embodiment, as Figure 4 The first partition 27 and the second partition 28 are driven by the same lead screw 29. The lead screw 29 is connected to the first partition 27 and the second partition 28 through a worm gear and a bevel gear set, and is driven by a motor. The lead screw 29 is a coaxial reverse lead screw, and when it rotates, the first partition 27 and the second partition 28 can rotate in opposite directions.

[0059] Please see Figure 4 The lead screw 29 transmits power through a worm gear. A bevel gear set is fixedly connected to the side of the worm gear set, and a transmission gear is fixedly connected below the bevel gear set. A rack is fixedly provided on the inner ring of the ring seat 271. The transmission gear meshes with the rack to transmit power. The lead screw 29 is a reverse lead screw, which can cause the partition 1 27 and partition 28 to rotate in opposite directions when transmitting power.

[0060] In summary, when this device is implemented, the collection trolley 3 is pushed onto the lifting platform 5, and automatic collection is carried out under the action of the controller. The operator only needs to replace the collection trolley 3. In addition, during the collection process, the stones and coal can be cooled and dusted by the cooling mechanism 2, so that the temperature of the stones and coal in the collection trolley 3 is low and there is no dust, which effectively prevents workers from being burned and dust from harming their health.

[0061] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
