[0002] Vertical coal mills are large-scale grinding equipment that integrates crushing, grinding, drying, sorting, and conveying functions, and are widely used in industries such as cement, power, and metallurgy. As a core piece of equipment in modern industrial coal powder preparation, the performance of the separator in a vertical coal mill directly affects the fineness of the coal powder, the sorting efficiency, and the stability of the system.
[0003] Existing separators commonly suffer from localized coal powder accumulation due to airflow turbulence under conditions of high humidity or low fine powder content. Coarse particles tend to adhere to the surfaces of the guide plates and return cones, causing blockages. Utility Model Content
[0004] In view of the common problem of local coal powder accumulation caused by airflow turbulence in existing separators under high humidity or low fine powder content conditions, and the easy adhesion of coarse particles to the surface of the guide plate and return cone, which causes blockage, this utility model proposes an anti-blockage vertical coal mill separator to overcome the above-mentioned technical problems existing in the existing related technologies.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0006] This utility model relates to a clog-resistant vertical coal mill separator, comprising a separation component, a driving component on the outer surface of the separation component, a rotating component on the outer surface of the driving component, the rotating component being rotatably connected to the interior of the separation component, and a clearing component inside the separation component. The separation component is used to separate coarse coal powder and fine coal powder, the driving component is used to drive the rotating component to rotate, the rotating component is used to move the coarse coal powder, and the clearing component is used to clear the blockage of the separation component.
[0007] Furthermore, the separation component includes a coal chutes, the outer surface of which is fixedly connected to a cone and a cover plate, the top of which is fixedly connected to a first coal outlet pipe, and the outer surface of which is fixedly connected to a second coal outlet pipe.
[0008] Furthermore, the drive assembly includes a bracket, which is fixedly mounted on the top of the cover plate. A motor is fixedly mounted on the top of the bracket, and a gear is fixedly mounted on the output shaft end of the motor. A gear ring meshes with the outer surface of the gear, and both the gear and the gear ring are rotatably connected to the cover plate.
[0009] Furthermore, the rotating assembly includes a rotating ring, which is rotatably connected to the cover plate. The top of the rotating ring is fixedly connected to a toothed ring, and a vertical rod is fixedly installed at the bottom of the rotating ring. A push plate is fixedly installed at the lower end of the vertical rod, and the push plate is located inside the cone.
[0010] Furthermore, the unblocking assembly includes an electric push rod, a baffle is fixedly installed on the movable end of the electric push rod, an unblocking rod is fixedly installed on the outer surface of the baffle, a guide cylinder is slidably connected to the outer surface of the unblocking rod, the guide cylinder is fixedly connected to the second coal outlet pipe, and the unblocking rod is located inside the second coal outlet pipe.
[0011] Furthermore, a first square plate is fixedly connected to the outer surface of the second coal outlet pipe, a connecting rod is fixedly installed on the outer surface of the first square plate, a second square plate is fixedly connected to the first square plate through the connecting rod, the electric push rod is fixedly installed on the outer surface of the second square plate, and a guide rod is fixedly connected to the outer surface of the first square plate, the guide rod being slidably connected to the baffle.

[0013] This utility model has the following beneficial effects:
[0014] 1. This utility model connects the separation component and the unblocking component. Coarse coal powder falls to the bottom of the separation component. When the coarse coal powder is discharged from the discharge port at the bottom of the separation component, the unblocking component is activated, causing the unblocking component to reciprocate within the discharge port at the bottom of the separation component. At this time, the unblocking component can push the coarse coal powder in the discharge port at the bottom of the separation component to move. The coarse coal powder that has accumulated can push the unblocking component aside, thereby unblocking the separation component and preventing the coarse coal powder from clogging the separation component.
[0015] 2. This utility model uses the connection between the gear ring and the rotating ring. The motor drives the gear to rotate the gear ring, which in turn drives the rotating ring and the vertical rod to rotate. The vertical rod drives the push plate to rotate inside the cone, so that the push plate can push the coarse coal powder inside the cone to move. When the coarse coal powder moves to the connection between the cone and the second coal outlet pipe, it is discharged from the second coal outlet pipe under the action of gravity, thus avoiding the accumulation of coarse coal powder inside the cone.
[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0027] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.
[0028] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.
[0029] Please see Figures 1-7 As shown, this utility model is an anti-clogging vertical coal mill separator, including a separation component 1. A drive component 2 is provided on the outer surface of the separation component 1, and a rotating component 3 is provided on the outer surface of the drive component 2. The rotating component 3 is rotatably connected to the interior of the separation component 1. A clearing component 4 is provided inside the separation component 1. The separation component 1 is used to separate coarse coal powder and fine coal powder. The drive component 2 is used to drive the rotating component 3 to rotate. The rotating component 3 is used to push the coarse coal powder to move. The clearing component 4 is used to clear the blockage of the separation component 1.
[0030] After connecting the separation component 1 to the vertical coal mill, the coal blocks pass through the separation component 1 and enter the vertical coal mill. The vertical coal mill grinds the coal blocks and blows out hot air to dry the coal powder. The coal powder blown by the hot air returns to the separation component 1 from the side. Under the action of gravity, the coarse coal powder and fine coal powder are separated. The drive component 2 on the separation component 1 is started. The drive component 2 drives the rotating component 3 to rotate. When the rotating component 3 rotates inside the separation component 1, it can push the coarse coal powder to move, so that the coarse coal powder is discharged from the discharge port of the separation component 1. The unblocking component 4 on the separation component 1 is started to unblock the discharge port of the separation component 1 to prevent blockage.
[0031] This invention connects the separation component 1 and the unblocking component 4. Coarse coal powder falls to the bottom of the separation component 1. When the coarse coal powder is discharged from the discharge port at the bottom of the separation component 1, the unblocking component 4 is activated, causing the unblocking component 4 to reciprocate within the discharge port at the bottom of the separation component 1. At this time, the unblocking component 4 can push the coarse coal powder within the discharge port at the bottom of the separation component 1 to move. The coarse coal powder that has accumulated can push the unblocking component 4 aside, thereby unblocking the separation component 1 and preventing the coarse coal powder from clogging the separation component 1.
[0032] In one embodiment, the separation component 1 includes a coal chuting pipe 101, with a cone 102 and a cover plate 103 fixedly connected to the outer surface of the coal chuting pipe 101, a first coal outlet pipe 104 fixedly connected to the top of the cover plate 103, and a second coal outlet pipe 105 fixedly connected to the outer surface of the cone 102.
[0033] Coal lumps are fed into the vertical coal mill through the coal drop pipe 101. The vertical coal mill grinds the coal lumps and blows out hot air to dry the coal powder. At the same time, the coal powder is blown up and enters the gap between the cone 102 and the cover plate 103. The lighter fine coal powder is blown out from the first coal outlet pipe 104 on the cover plate 103, while the heavier coarse coal powder falls into the cone 102 and is discharged from the second coal outlet pipe 105.
[0034] In one embodiment, the drive assembly 2 includes a bracket 201, which is fixedly mounted on the top of the cover plate 103. A motor 202 is fixedly mounted on the top of the bracket 201. A gear 203 is fixedly mounted on the output shaft end of the motor 202. A gear ring 204 meshes with the outer surface of the gear 203. Both the gear 203 and the gear ring 204 are rotatably connected to the cover plate 103.
[0035] When the motor 202 is started, the output shaft of the motor 202 drives the gear 203 to rotate. The gear 203 meshes with the gear ring 204, causing the gear 203 to drive the gear ring 204 to rotate. The bracket 201 provides a fixed position for the motor 202 to be installed, so that the motor 202 remains stable during operation.
[0036] In one embodiment, the rotating assembly 3 includes a rotating ring 301, which is rotatably connected to the cover plate 103. The top of the rotating ring 301 is fixedly connected to the toothed ring 204. A vertical rod 302 is fixedly installed at the bottom of the rotating ring 301. A push plate 303 is fixedly installed at the lower end of the vertical rod 302. The push plate 303 is located inside the cone 102.
[0037] The toothed ring 204 drives the rotating ring 301 to rotate, and the rotating ring 301 drives the vertical rod 302 to rotate inside the cone 102. The push plate 303 at the lower end of the vertical rod 302 rotates accordingly. During the rotation, the push plate 303 can push the coarse coal powder inside the cone 102 to move, so that the coarse coal powder moves to the connection between the cone 102 and the second coal outlet pipe 105, thus avoiding the situation where the coarse coal powder accumulates inside the cone 102 and cannot be discharged to the second coal outlet pipe 105.
[0038] In one embodiment, the unblocking component 4 includes an electric push rod 401, a baffle 402 is fixedly installed on the movable end of the electric push rod 401, an unblocking rod 403 is fixedly installed on the outer surface of the baffle 402, a guide cylinder 404 is slidably connected to the outer surface of the unblocking rod 403, the guide cylinder 404 is fixedly connected to the second coal outlet pipe 105, and the unblocking rod 403 is located inside the second coal outlet pipe 105.
[0039] When the electric push rod 401 is activated, the movable end of the electric push rod 401 pushes the baffle 402 to move, causing the baffle 402 to drive the unblocking rod 403 to reciprocate within the second coal outlet pipe 105. At this time, the unblocking rod 403 pushes the coarse coal powder blocking the second coal outlet pipe 105 to move, thereby unblocking the second coal outlet pipe 105. The baffle 402 can block the coarse coal powder discharged from the second coal outlet pipe 105, preventing the coarse coal powder from falling onto the outer surface of the electric push rod 401.
[0040] In one embodiment, for the second coal outlet pipe 105, a first square plate 5 is fixedly connected to the outer surface of the second coal outlet pipe 105, a connecting rod 6 is fixedly installed on the outer surface of the first square plate 5, a second square plate 7 is fixedly connected to the first square plate 5 through the connecting rod 6, the electric push rod 401 is fixedly installed on the outer surface of the second square plate 7, a guide rod 8 is fixedly connected to the outer surface of the first square plate 5, and the guide rod 8 is slidably connected to the baffle 402.
[0041] The connecting rod 6 is a double-ended screw, and a nut is threaded onto the outer surface of the connecting rod 6. The first square plate 5 and the second square plate 7 are connected together through the connecting rod 6 and the nut. The guide rod 8 can guide and support the movement of the baffle 402.
[0042] In one embodiment, for the cover plate 103, a housing 9 is fixedly connected to the top of the cover plate 103, and the motor 202, gear 203 and gear ring 204 are all located inside the housing 9.
[0043] The cover 9 can protect the motor 202, gear 203 and gear ring 204, and prevent foreign objects from being caught in the rotating gear 203 and gear ring 204.
[0044] Through the above technical solution, 1. By connecting the separation component 1 and the unblocking component 4, coarse coal powder falls to the bottom of the separation component 1. When the coarse coal powder is discharged from the discharge port at the bottom of the separation component 1, the unblocking component 4 is activated, causing the unblocking component 4 to reciprocate within the discharge port at the bottom of the separation component 1. At this time, the unblocking component 4 can push the coarse coal powder within the discharge port at the bottom of the separation component 1 to move. The accumulated coarse coal powder can then push aside the unblocking component 4, thereby unblocking the separation component 1 and preventing coarse coal powder from clogging the separation component. 1. Inside; 2. Through the connection of the gear ring 204 and the rotating ring 301, the motor 202 drives the gear 203 to rotate the gear ring 204, which in turn drives the rotating ring 301 and the vertical rod 302 to rotate. The vertical rod 302 drives the push plate 303 to rotate inside the cone 102, so that the push plate 303 can push the coarse coal powder inside the cone 102 to move. When the coarse coal powder moves to the connection between the cone 102 and the second coal outlet pipe 105, it is discharged from the second coal outlet pipe 105 under the action of gravity, thus preventing the coarse coal powder from accumulating inside the cone 102.
