Description

Technical Field

[0001] The present invention relates to a cleaning device and method for the water tank of a sintering annular cooler, in particular to a device and method capable of cleaning impurities accumulated on the inner wall of the water tank of the annular cooler, belonging to the technical field of cleaning equipment for the water tank of the annular cooler. Background Art

[0002] The sintered finished ore can be transported to a designated location by belt only after cooling down. The annular cooler is a common device for cooling the sintered finished ore; its edge part adopts water seal. A ring-shaped water tank is arranged at the bottom edge of the annular cooler and rotates along with the rotation of the inside of the annular cooler. An annular inserting plate is arranged at the top edge of the annular cooler, and the position of the annular inserting plate is fixed, and its bottom end is inserted into the ring-shaped water tank but does not touch it. Water is injected into the ring-shaped water tank, and water forms a seal between the water tank and the inserting plate; during the actual production process, there are a large number of floating dusts diffused inside the annular cooler, and some of them will sink into the water in the water tank. After the annular cooler operates for a period of time, a large amount of silt will accumulate in the water tank, which will increase the load of the rotation of the water tank, and when too much silt accumulates, it will affect the water seal effect of the edge of the annular cooler; therefore, it is necessary to regularly clean the silt in the water tank. Due to the huge floor area of the annular cooler, the labor intensity is high during manual cleaning; in addition, during manual cleaning, it is generally carried out outside the annular cooler, that is to say, the silt between the inserting plate and the inner ring baffle of the water tank cannot be effectively cleaned, resulting in incomplete cleaning operations; therefore, a cleaning device and method are needed to deeply clean the silt between the inner ring baffle and the outer ring baffle of the water tank, minimize omissions as much as possible, and ensure the normal operation of the edge sealing system of the annular cooler.

[0013] A method for cleaning a water tank of a sintering ring cooler comprises the following steps: The water tank of the ring cooler should be cleaned once every cleaning cycle; In the initial state, the first rope puller pulls the first scraper to make it close to the first lifting plate, and the first scraper is located directly above the water tank and does not contact the water; the second rope puller pulls the second scraper to make it close to the second lifting plate, and the second scraper is located directly above the water tank and does not contact the water; under the pulling of the third winch, the inclined long plate is located directly above the water tank and does not contact the water; Step 1: When cleaning is required, start the first winch, the second winch and the third winch, so that the bottom ends of the first scraper, the second scraper and the inclined long plate are all pressed against the bottom end surface of the water tank; Step 2: Start the first rope puller and the second rope puller. When the first scraper and the second scraper are not restricted by the rope puller, since there is an angle between the first scraper and the second scraper and the water flow direction, the first scraper and the second scraper are automatically turned over by the impact of the water flow after they are not restricted by the rope puller.

Similarly, the second scraper touches the inner wall of the inner baffle of the water tank. Step 3: Start the second hydraulic cylinder to extend the second transverse plate, and the second transverse plate passes under the annular insert plate, so that the mud scraped by the second scraper is transferred to the area between the annular insert plate and the outer ring side wall of the water tank; Step 4: Start the motor and vibrator. The motor drives the driving gear to rotate, and the driving gear drives the tooth chain to move. During the movement of the tooth chain, the elastic scraper on it moves circumferentially. The elastic scraper touches and presses on the top surface of the inclined long plate and moves upward. During the upward movement of the elastic scraper, the mud accumulated at the bottom of the inclined long plate is scraped to the top of the inclined long plate, and then the mud naturally falls onto the chute. The chute itself has an inclined angle, and coupled with the vibration of the vibrator, the mud on the chute naturally slides down and falls into the collection bucket; Step 5: During the silt removal process, always pay attention to the difference in liquid levels on both sides of the scraper, and control the sliding of the first transverse plate through the first hydraulic cylinder, thereby controlling the size of the square hole channel under the first scraper, and thereby controlling the flow rate of water when it passes through the gap between the two scrapers; when the difference in liquid levels on both sides of the scraper is large, control the sliding of the first transverse plate through the first hydraulic cylinder to reduce its obstruction of the square hole of the first scraper, thereby expanding the water flow channel; conversely, when the difference in liquid levels is small, expand the obstruction of the square hole of the first scraper by the first transverse plate to reduce the water flow channel; avoid overflowing the water tank due to excessive water level on one side due to the obstruction of the scraper; Step 6: After running for a period of time, when there is no more silt on the chute, turn off the motor and vibrator, control the first hydraulic cylinder and the second hydraulic cylinder to retract the transverse plate; start the first rope puller and the second rope puller to retract the first scraper and the second scraper; the first winch, the second winch and the third winch are driven to lift and reset each part, and the cleaning operation of the annular cooler tank is completed.

[0014] The present invention scrapes away the sludge accumulated between the annular plug plate and the outer ring side wall of the water tank through the outer scraping part, and cleans the sludge accumulated between the annular plug plate and the inner ring side wall of the water tank through the inner scraping part; the sludge scraped off in the water tank is transferred through the mud cleaning part and moved to an external collection bucket; the redirecting piece effectively redirects the sludge between the annular plug plate and the inner ring side wall of the water tank to between the annular plug plate and the outer ring side wall of the water tank, so that the sludge is concentrated and enters the mud cleaning part, and finally the sludge is transferred to the outside through the mud cleaning part.

[0026] The present invention comprises the following steps: The water tank 2 of the ring cooler is cleaned once every cleaning cycle; In the initial state, the first rope puller 7 pulls the first scraper 8 to make it close to the first lifting plate 4, and the first scraper 8 is located directly above the water tank 2 without contacting the water; the second rope puller 15 pulls the second scraper 16 to make it close to the second lifting plate 12, and the second scraper 16 is located directly above the water tank 2 without contacting the water; under the pulling of the third winch 20, the inclined long plate 23 is located directly above the water tank 2 without contacting the water; Step 1: When cleaning is required, the first hoist 3, the second hoist 11 and the third hoist 20 are started, so that the first scraper 8, the second scraper 16 and the inclined long plate 23 move downward under their own weight, and the bottom ends of each of them touch the bottom end surface of the water tank 2; Step 2: Start the first rope puller 7 and the second rope puller 15. When the first scraper 8 and the second scraper 16 are not restricted by the rope puller, since there is an angle between the first scraper 8 and the second scraper 16 and the water flow direction, the first scraper 8 and the second scraper 16 will be automatically turned over by the impact of the water flow after they are not restricted by the rope puller.
