Description
Technical Field
[0001] The utility model belongs to the technical field of sintering pelletizing ring coolers, and in particular relates to an intelligent silt removal system for a water tank on a ring cooler. Background Art
[0002] The ring cooler is one of the key equipment in the sintering pelletizing process, and its main function is to cool the sintered pellets. In recent years, with the continuous improvement of the country's requirements for environmental protection and energy conservation and consumption reduction, waste heat recovery and waste heat power generation projects supporting the ring cooler have emerged. At the same time, the upgrading and transformation of the ring cooler is also continuously advancing, and its sealing form has gradually evolved from rubber seals, elastic seals, and magnetic seals to sand seals, water seals and other sealing forms.
[0003] New environmentally friendly annular coolers generally promote the U-shaped water seal method to isolate the internal and external environments on a large scale. A water tank is set between the mobile trolley and the fixed bellows. A partition is set in the water tank to form a U-shaped water seal to isolate the bellows from the external environment. The sealing pressure is ensured by the water level difference on both sides of the water tank. The water seal method can achieve absolute full sealing, and industrial new water is used to replace rubber seals, which significantly reduces costs.
[0004] In actual sintering pellet production, fine particles in the sintered pellets are blown into the water tank by the blown air and precipitated in the water tank to form sludge. As the sludge continues to accumulate, its thickness gradually increases, and the rotation resistance of the partitions in the water tank increases. When the sludge thickness reaches a certain level, the partitions in the water tank will be curled and torn, causing equipment accidents and affecting smooth production. Therefore, the sludge in the water tank needs to be cleaned regularly, and the existing treatment method is to use a shovel for manual cleaning. This method has three disadvantages: first, the size of the shovel is larger than the width of the trough, and the shovel is limited by space during cleaning, making it inconvenient to move; second, the sludge is located at the bottom of the trough, and during the cleaning process, the sludge needs to pass through the upper water layer. The sludge and water have a certain fluidity after mixing, and it is difficult to clean it thoroughly; third, during normal production, the annular cooler is running, and manual dredging operations have great safety risks and cannot be carried out. Dredging operations can only be completed during maintenance periods, but when production parameters fluctuate, the sludge accumulation rate in the trough increases, and the sludge grows to the cleaning thickness in a short period of time, making dredging operations impossible. The annular cooler "operates with illness" and the risk of failure is significantly increased.
[0005] Therefore, it is necessary to develop an intelligent dredging system for the water tank of the annular cooler, which can perform dredging operations when the annular cooler is in normal production and operation, reduce the difficulty of dredging, and improve the efficiency and effect of dredging.

[0031] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with specific embodiments and drawings. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.
[0032] Embodiment 1:
[0033] like Figure 1-4As shown, an intelligent dredging system for the upper water tank of an annular cooler includes a connecting platform 1, an upper water tank 2 is arranged below the connecting platform 1, and a gathering mechanism 3 and a dredging mechanism 4 are sequentially installed at the bottom of the connecting platform 1 in the order of facing the running direction of the upper water tank 2, and the lower parts of the gathering mechanism 3 and the dredging mechanism 4 are inserted into the upper water tank 2. The gathering mechanism 3 is used to detect the deformation of the inner wall of the upper water tank 2 and to gather the silt and foreign matter in the upper water tank 2 to facilitate the subsequent dredging work.
[0034] The gathering mechanism 3 includes a gathering support rod 301 located inside the upper water tank 2, the gathering support rod 301 is installed at the bottom of the connecting platform 1 through a telescopic cylinder 302, and both sides of the gathering support rod 301 are connected with gathering scrapers 305 in an inclined and movable manner through a front telescopic rod 303 and a rear telescopic rod 304. The gathering scrapers 305 are used to scrape off the sludge attached to the inner walls of both sides of the upper water tank 2 and gather the sludge and foreign matter at the bottom of the upper water tank 2.
[0035] The dredging mechanism 4 is provided with a swivel bracket 401, the top of which is fixed on the connecting platform 1 through a swivel cylinder 402, and the lower end of the swivel bracket 401 is inserted into the upper water tank 2 and is hinged with a collecting bucket 403. The collecting bucket 403 is used to collect the silt and foreign matter in the upper water tank 2 and clean them to the outside of the upper water tank 2.
[0036] The front telescopic rod 303 is a round tube with blocked ends. The front telescopic rod 303 is sleeved with a front movable rod 306. A circular baffle 307 is welded to one end of the front movable rod 306 located inside the front telescopic rod 303. The other end of the front movable rod 306 passes through the front telescopic rod 303 and extends to the outside of the front telescopic rod 303. Two baffle rings 308 are welded to one end of the front movable rod 306 located outside the front telescopic rod 303, and a bull's eye roller 309 is threaded at the end position. The bull's eye roller 309 abuts against the inner wall of the side of the upper water tank 2. A spring 310 is sleeved on the front movable rod 306 between the front telescopic rod 303 and the baffle ring 308. The two ends of the spring 310 are respectively welded to the front telescopic rod 303 and the baffle ring 308. Since the upper water tank 2 is deformed, the front movable rod 306 cannot be rigidly pressed against the inner wall of the upper water tank 2, otherwise the upper water tank 2 will be damaged. When the upper water tank 2 is in operation, the bull's eye roller 309 rolls on the inner wall of the lower water tank 2 and moves along with the deformation.
[0037] The rear telescopic rod 304 is a round tube with blocked ends. A rear movable rod 311 is sleeved inside the rear telescopic rod 304. A circular baffle 307 is welded to one end of the rear movable rod 311 located inside the rear telescopic rod 304. The other end of the rear movable rod 311 passes through the rear telescopic rod 304 and extends to the outside of the rear telescopic rod 304. Two baffle rings 308 are welded to one end of the rear movable rod 311 located outside the rear telescopic rod 304 and a bull's eye roller 309 is threaded at the end. A spring 310 is sleeved on the rear movable rod 311 between the rear telescopic rod 304 and the baffle 307. The two ends of the spring 310 are respectively welded to the rear telescopic rod 304 and the baffle 307. When there is a large foreign object, the gathering scraper 305 is squeezed to both sides. At this time, the bull's eye roller 309 may contact the inner wall of the upper water tank 2. Since the rear movable rod 311 is retractable, damage to the upper water tank 2 is avoided.
[0038] The gathering scraper 305 is provided with two strip holes 312 corresponding to the front movable rod 306 and the rear movable position. The front movable rod 306 and the rear movable rod 311 respectively pass through the corresponding strip holes 312. The gathering scraper 305 is connected between the two retaining rings 308 of the front movable rod 306 and the two retaining rings 308 of the rear movable rod 311 through the strip holes 312. The front telescopic rod 303 and the rear telescopic rod 304 are respectively connected to the gathering scraper 305 through the front movable rod 306 and the rear movable rod 311. A contraction block 313 is welded on the gathering scraper 305 below the front movable rod 306. The contraction block 313 is a right triangle. The contraction block 313 can be squeezed through the two sides of the upper water tank 2 when the gathering scraper 305 descends to the upper water tank 2, so that the front movable rod 306 retracts inward, so that the bull's eye roller 309 on the front movable rod 306 abuts against the inner wall of the upper water tank 2.
[0039] A rubber skin 314 is fixed to the bottom of the gathering scraper 305, and the bottom end of the rubber skin 314 abuts against the inner wall of the bottom of the upper water tank 2. The gathering scraper 305 is installed with a displacement sensor 315 above the front movable rod 306, and the displacement sensor 315 is electrically connected to the deformation alarm.
[0040] The gathering scrapers 305 on both sides of the gathering support rod 301 form a trapezoidal structure with one end expanded and the other end contracted, which is used to gather sludge and foreign matter. The expanded ends of the two gathering scrapers 305 face the running direction of the water tank.
[0041] A tension sensor 404 is hinged at the middle upper position of the slewing bracket 401, and the tension sensor 404 is hinged to a support frame 406 through a lifting cylinder 405. One end of the support frame 406 is hinged to the slewing bracket 401, and the other end of the support frame 406 is hinged to the bottom of the collecting bucket 403. A vertical rod 407 is welded on the support frame 406, and the top of the vertical rod 407 is hinged to the top of the collecting bucket 403 through a flip cylinder 408. The slewing bracket 401 is hinged to receive the collecting bucket 403 through the tension sensor 404, the lifting cylinder 405, the support frame 406, the flip cylinder 408, and the vertical rod 407. The tension sensor 404 can detect the weight of the hinged end of the dredging mechanism 4, and the collected material is discharged to the outside of the upper water tank 2 when the weight reaches the limit.
[0042] The collecting bucket 403 is in the shape of a bucket with one side open. The bottom of the collecting bucket 403 is close to the bottom inner wall of the upper water tank 2. The upper part of the collecting bucket 403 is hollowed out. A screen 409 is welded inside the hollow of the collecting bucket 403. When the collecting bucket 403 is located inside the upper water tank 2, the open side of the collecting bucket 403 faces the running direction of the upper water tank 2.
[0043] Embodiment 2:
[0044] The working method of the utility model is realized by the following steps:
[0045] (1) Before desilting, ensure that the annular cooler trolley operates without faults under normal production conditions, and that all components of the water tank intelligent desilting system are in good condition. After starting the gathering mechanism 3, the telescopic cylinder 302 extends, and the gathering support rod 301 descends to the inside of the upper water tank 2. During this process, the side wall of the upper water tank 2 squeezes the contraction block 313, thereby driving the two front movable rods 306 to move inward, and the springs 310 on the two front telescopic rods 303 contract, and finally the bull's eye rollers 309 on the two front telescopic rods 303 abut against the inner wall of the upper water tank 2;
[0046] (2) After the annular cooler is running, the upper water tank 2 also rotates and runs accordingly. The sludge and foreign matter in the upper water tank 2 are gathered after passing through the two gathering clamps. When the large foreign matter passes through the gathering mechanism 3, it squeezes the constricted end of the two gathering scrapers 305, and the spring 310 of the rear telescopic rod 304 is squeezed and stretched, so that the distance between the constricted ends of the two gathering scrapers 305 becomes larger, thereby allowing the foreign matter to pass through, thereby preventing the large foreign matter from being stuck;
[0047] (3) The bull's eye roller 309 of the front telescopic rod 303 of the gathering mechanism 3 always rolls against the inner wall of the upper water tank 2. When the upper water tank 2 is deformed, the spring 310 on the front telescopic rod 303 will be compressed, and the gathering scraper 305 and the displacement sensor 315 thereon will move accordingly. The displacement limit of the displacement sensor 315 is set. When the deformation degree is large and exceeds the displacement limit, the deformation alarm is triggered and the machine is shut down, and the staff inspects the deformed part;
[0048] (4) After the silt removal mechanism 4 is started, the lifting cylinder 405 is extended to make the collecting bucket 403 fall, and at the same time, the flipping cylinder 408 is actuated to make the bottom of the collecting bucket 403 close to the inner wall of the bottom of the upper water tank 2, and the gathered silt and foreign matter enter the collecting bucket 403. The detection limit of the tension sensor 404 is set, and the tension sensor 404 detects the total weight of the collecting bucket 403 in real time. When the total weight of the collecting bucket 403 and the silt and foreign matter in the collecting bucket 403 exceeds the limit, the flipping cylinder 408 retracts first, and the collecting bucket 403 flips up. The lifting cylinder 405 retracts again, driving the collecting bucket 403 to move up. Prevent the silt and water in the bucket from flowing back to the upper water tank 2 from the front mouth when out of the water, and make the bottom height of the collecting bucket 403 higher than the height of the upper water tank 2, the water in the collecting bucket 403 flows out from the screen 409, the silt and foreign matter are blocked, the rotary cylinder 402 is activated, the dredging mechanism 4 rotates to make the collecting bucket 403 located outside the upper water tank 2, the flipping cylinder 408 is extended to make the collecting bucket 403 flip down, and the silt and foreign matter in the collecting bucket 403 are discharged to the outside of the upper water tank 2, then the flipping cylinder 408 retracts, the rotary cylinder 402 is activated, and the lifting cylinder 405 is extended to reset the collecting bucket 403 to continue the dredging work.
[0049] (5) After the dredging work is completed, the telescopic cylinder 302 retracts to raise the gathering mechanism 3, and the lifting cylinder 405 retracts to lift the collecting bucket 403 of the dredging mechanism 4, thereby not hindering the normal operation of the water tank 2 on the annular cooler.
[0050] It should be noted that the gathering mechanism 3 and the dredging mechanism 4 are all controlled by the PLC programmable controller. The telescopic cylinder 302, the displacement sensor 315, the rotary cylinder 402, the tension sensor 404, the lifting cylinder 405, and the flip cylinder 408 are all electrically connected to the PLC programmable controller. The PLC programmable controller is a commonly used technical means of automation control technology, and can set the trigger conditions for the telescopic cylinder 302, the rotary cylinder 402, the lifting cylinder 405, and the flip cylinder 408 to act.
[0051] A collection box with a screening function and a cleaning system can be placed at the sludge and foreign matter discharge position outside the upper water tank 2, so that the sludge and foreign matter can be discharged into the collection box, and the sludge and foreign matter can be separated at the same time. The cleaning system includes a water pipe, a solenoid valve and a nozzle. The solenoid valve is electrically connected to the PLC programmable controller. When the collection bucket 403 is discharged, the solenoid valve opens, and water is sprayed from the water pipe through the nozzle to clean the collection bucket 403, so as to prevent the sludge from remaining after the collection bucket 403 is discharged.

Without departing from the design concept of the present invention, various modifications and improvements made by ordinary persons in the art to the technical solution of the present invention shall fall within the scope of protection of the present invention.
