Description

Technical Field

[0001] The invention relates to the field of metallurgy, and in particular to a structure for automatically cleaning dust accumulation in a water tank of an annular cooler. Background Art

[0002] The temperature of hot sintered ore produced by sintering is 750-800℃ when it is unloaded at the tail of the machine. In modern sintering technology and safety requirements, it is cooled to below 120℃. The hot sintered ore is unloaded to the ring cooler trolley through the unloading chute. The cold air is blown in from the bottom of the trolley by the blower, and is discharged from the smoke hood after heat exchange through the sintered ore layer. The trolley needs to be equipped with a bellows, and a water tank seal is set between the bellows and the bottom of the trolley. The water tank is filled with water to achieve water sealing. However, during use, dust is easy to accumulate in the water tank. Due to the blast cooling method of the ring cooler, it is time-consuming and labor-intensive to manually clean the accumulated material in the water tank, and there are problems of high safety risks.

[0003] Therefore, it is necessary to develop a new type of automatic cleaning structure for dust accumulation in the water tank of the annular cooler to facilitate operation, reduce operating risks, and reduce manual labor. Summary of the invention

[0004] Purpose of the invention: In view of the shortcomings and defects of the prior art, the present invention provides a structure for automatically cleaning dust accumulation in the water tank of a ring cooler, which utilizes the relative movement of the ring cooler with the ring cooler during operation to automatically clean the dust accumulation in the water tank; automatic cleaning reduces manual labor, and real-time cleaning reduces the energy consumption of the ring cooler, with high safety.

[0005] Technical solution: The invention discloses an automatic dust cleaning structure for a ring cooler water tank, which is characterized in that a scraper body in the shape of a water wheel is arranged at the ring cooler water tank, a plurality of buckets are arranged around the scraper body, the scraper body is connected to a motor, a discharge chute is arranged on the side of the scraper body, and a sludge bucket is arranged under the discharge chute.

[0006] Wherein, the bucket moves in the direction opposite to the running direction of the water tank of the annular cooler under the drive of the motor.

[0007] Wherein, the number of the buckets is 4-6.

[0008] Wherein, the bucket is an angled structure or a semicircular arc structure.

[0009] Among them, after the bucket enters the water tank of the annular cooler, the distance between it and the bottom of the water tank of the annular cooler is more than 1 cm, and the distance between it and the side of the water tank of the annular cooler is more than 1.5 cm.

[0010] Beneficial effects: Compared with the prior art, the present invention has the following significant advantages: Through actual operation, the present invention can not only clean up the accumulated materials in the water tank of the annular cooler in time, reduce the operating load and energy consumption of the annular cooler, and avoid equipment failure, but also save the cost of manual cleaning and reduce the labor intensity of the cleaning personnel. At the same time, the safety risks of the cleaning personnel are reduced. Before the transformation, it took 360 man-hours to manually clean one annular cooler per year. After the transformation, it took 100 man-hours to manually clean one annular cooler per year, and the man-hours were reduced by 72.22%. The device can also be used for automatic cleaning operations of accumulated materials in the running water tank in other similar scenarios.

[0011] The present invention installs a cleaning device in the shape of a waterwheel based on the operating characteristics of the ring cooler and the characteristics of material accumulation in the water tank. The cleaning device uses the relative movement of the ring cooler with the ring cooler during operation to achieve real-time cleaning of dust accumulation and reduce the labor intensity of manual cleaning. The ring cooler achieves the purpose of stable operation and reliable performance. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1 It is a structural schematic diagram of the present invention;

[0013] In the figure, 1 is the scraper body; 2 is the bucket; 3 is the motor; 4 is the ring cooler water tank; 5 is the discharge chute; and 6 is the sludge barrel. DETAILED DESCRIPTION

[0014] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0015] The automatic dust cleaning structure of the annular cooler water tank of the present invention comprises a scraper body 1 in the shape of a waterwheel at the annular cooler water tank 4, a plurality of buckets 2 being arranged around the scraper body 1, the scraper body 1 being driven by a motor 3 to shovel the dust in the annular cooler water tank 4 into the bucket 2, the bucket 2 starting to unload as the scraper body 1 rotates beyond the top of the circle, a unloading chute 5 being arranged at the unloading location, and the material falling into a sludge barrel 6 on the ground along with the unloading chute 5.

[0016] The bucket 2 moves in the direction opposite to the running direction of the annular cooler water tank 4 under the drive of the motor 3, and shovels the dust in the annular cooler water tank 4 into the bucket 2. The number of buckets 2 is 4-6. The bucket 2 is an angle structure or a semi-circular arc structure. After the bucket 2 enters the annular cooler water tank 4, the distance between the bucket 2 and the bottom of the annular cooler water tank 4 is more than 1 cm, and the distance between the bucket 2 and the side of the annular cooler water tank 4 is more than 1.5 cm.

[0017] The bucket of the present invention is made of wear-resistant material, and the rotation speed is controlled by the motor frequency conversion to match the operating speed of the ring cooler. The bucket rotates to the bottom of the water tank and forms a cut angle (the distance from the bottom of the water tank is 1cm and the distance from the side of the water tank is 1.5cm. The bucket is semicircular and the arc is the same as the arc of the water tank). The bottom material is shoveled into the bucket. The bucket starts to unload as the body rotates beyond the top of the circle. A chute is provided at the unloading place. The horizontal distance between the chute and the unloading bucket is 5cm. Using the parabola principle, the bucket unloads the material into the chute, and the material falls into the ground sewage bucket with the chute. The sewage bucket can be replaced for easy transportation.

[0018] The rotary cleaning device is equipped with limit protection. When the resistance is large, the rotary device will shift, and the alarm will be triggered to shut down the machine to avoid equipment failure.
