Description

Technical Field

[0001] This utility model relates to a sludge removal device for an annular cooling water tank, belonging to the technical field of sintering machine equipment in the metallurgical industry. Background Technology

[0002] The annular cooling water tank is an important component of the annular cooler, mainly used for cooling sintered ore and recovering waste heat in the metallurgical industry. The annular cooler in the sintering workshop adopts a water-sealed structure, which has good dust suppression and heat removal effects. However, with prolonged operation, some dust from the finished product falls into the water tank during production, accumulating and gradually increasing the operating resistance of the annular cooler. In severe cases, this can lead to overload and shutdown. In steel production, 2-3 hours per shift are spent shoveling out the accumulated sludge from the water tank and then dumping it onto the finished product conveyor belt, increasing the workload and reducing efficiency. To solve these problems, Chinese patent CN2022216676368, entitled "A Novel Sludge Cleaner for Cleaning the Annular Cooler Water Tank," uses a rotating hopper to scrape the sludge from the annular cooler water tank. During the upward movement, the scraped sludge is continuously discharged from the inclined plate inside the rotating hopper onto a receiving plate, which then discharges the sludge onto a trolley. However, its hopper cannot reach the bottom of the water tank, making it difficult to clean out the lower layer of sludge in the water tank and thus failing to effectively reduce the load on the annular cooler. Utility Model Content

[0003] The purpose of this invention is to provide a sludge removal device for annular cooling water tanks. The sludge removal wheel extends into the bottom of the annular cooling water tank for cleaning, which can remove the accumulated sludge from the lower layer of the annular cooling water tank and directly transport it to the trolley of the annular cooling machine, thereby better reducing the load on the annular cooling machine and solving the problems existing in the background technology.

[0004] The technical solution of this utility model is: A sludge removal device for an annular cooling water tank includes a sludge removal wheel, a motor reducer, an annular cooling water tank, a reducer base, and a reflective chute. The motor reducer is mounted on the reducer base next to the annular cooling machine. The sludge removal wheel is mounted on the output shaft of the motor reducer. The width of the sludge removal wheel matches the width of the annular cooling water tank, and the lower part of the sludge removal wheel enters the annular cooling water tank. The sludge removal wheel includes a wheel disc and buckets. There are four or more buckets with identical structures, evenly arranged on the outer circumference of the wheel disc. The buckets extend along... The bucket extends beyond the outer circumference of the wheel in the diameter direction. The width of the bucket is slightly smaller than the width of the annular cooler water tank and can enter the annular cooler water tank. The foremost end of the bucket is close to the bottom of the annular cooler water tank. The upper end of the reflective chute is fixed to the annular cooler water tank below the center of the wheel. The reflective chute is arranged inclined towards the inside of the annular cooler, and the lower end of the reflective chute is located above the trolley of the annular cooler. The bucket is arranged close to the side of the wheel closest to the annular cooler. The rotating bucket does not contact the reflective chute and will not interfere with it.

[0005] The bucket is welded together from a bottom plate and two side plates. The bottom plate is a curved arc plate, and the edges of the side plates welded on both sides are matching arcs, forming an arc-shaped bucket.

[0006] The arc-shaped bucket and the wheel are welded together by an arc plate to increase strength.

[0007] The reducer base is connected to the channel steel by bolts, and the channel steel is fixed on the foundation.

[0008] Using this invention, the cleaning wheel extends into the water tank of the annular cooler. As the cleaning wheel rotates inside the water tank, it carries the sludge out through the bucket on the wheel disc. With the continuous rotation of the wheel disc, the sludge in the bucket falls onto the reflective chute due to its own gravity and slides into the trolley of the annular cooler, greatly reducing the workload and improving the efficiency of the work. The sludge in the water tank of the annular cooler is itself finished fine ash. After cleaning the sludge, it is unloaded onto the trolley of the annular cooler, dried by hot ore, and then directly enters the finished product dust removal system. After being sucked away by the suction and discharge system, it is transported to the sintering batching room to participate in the batching. Existing technology involves cleaning the sludge, transporting it to the material yard, mixing it with the return ore, and then sending it to the batching room. However, due to the high moisture content, the transport and loading process may result in spillage or additional conveyor belt return trips, while also increasing the amount of on-site cleaning and sanitation work.

[0009] The beneficial effects of this utility model are: the mud cleaning wheel extends into the bottom of the ring cooler water tank for cleaning, which can remove the lower layer of accumulated mud in the ring cooler water tank and directly transport it to the ring cooler trolley, thus better reducing the load on the ring cooler.

[0011] The present invention will be further described below with reference to the accompanying drawings and examples.

[0012] A sludge removal device for an annular cooling water tank includes a sludge removal wheel 1, a motor reducer 2, an annular cooling water tank 3, a reducer base 4, and a reflective chute 7. The motor reducer 2 is mounted on the reducer base 4 next to the annular cooling machine 10. The sludge removal wheel 1 is mounted on the output shaft 14 of the motor reducer 2. The width of the sludge removal wheel 1 matches the width of the annular cooling water tank 3, and the lower part of the sludge removal wheel 1 enters the annular cooling water tank 3. The sludge removal wheel 1 includes a wheel disc 8 and buckets 9. There are four or more buckets 9 with identical structures, evenly arranged on the outer circumference of the wheel disc 8. 9 extends outward from the outer circumference of the wheel 8 along the diameter direction of the wheel 8. The width of the bucket 9 is slightly smaller than the width of the annular cooler water tank 3 and can enter the annular cooler water tank 3. The foremost end of the bucket 9 is close to the bottom of the annular cooler water tank 3. The upper end of the reflective chute 7 is fixed on the annular cooler water tank 3 below the center of the wheel 8. The reflective chute 7 is arranged inclined towards the inside of the annular cooler. The lower end of the reflective chute 7 is located above the trolley of the annular cooler 10. The bucket 9 is arranged close to the side of the wheel 8 near the annular cooler. The rotating bucket 9 does not contact the reflective chute 7 and will not interfere with it.

[0013] The bucket 9 is welded from a bottom plate 11 and two side plates 12. The bottom plate is a curved arc plate, and the edges of the side plates welded on both sides are matching arc shapes, forming an arc-shaped bucket. In one embodiment, one of the side plates is an extension of the wheel and is an integral structure with the wheel.

[0014] The arc-shaped bucket and the wheel 8 are welded together by an arc-shaped plate 13. The arc of the arc plate 13 is the same as the arc of the outer circumference of the wheel 8, which increases the strength.

[0015] The reducer base 4 is connected to the channel steel 6 by bolts 5, and the channel steel 6 is fixed on the foundation.

[0016] In this embodiment, there are five buckets 9, which are identical in structure and are evenly arranged on the outer circumference of the wheel 8.

[0017] Using this invention, the cleaning wheel extends into the water tank of the annular cooler. As the cleaning wheel rotates inside the water tank, it carries the sludge out through the bucket on the wheel disc. With the continuous rotation of the wheel disc, the sludge in the bucket falls onto the reflective chute 7 due to its own gravity and slides into the trolley of the annular cooler, greatly reducing the workload and improving the efficiency of the work. The sludge in the water tank of the annular cooler is itself finished fine ash. After cleaning the sludge, it is unloaded onto the trolley of the annular cooler, dried by hot ore, and then directly enters the finished product dust removal system. After being sucked away by the suction and discharge system, it is transported to the sintering batching room to participate in the batching. Existing technology involves cleaning the sludge, transporting it to the material yard, mixing it with the return ore, and then sending it to the batching room. However, due to the high moisture content, the transport and loading process may result in spillage or additional material carried back by the conveyor belt, while also increasing the amount of on-site cleaning and sanitation work.
