Abstract
Description
Technical Field
[0001] The invention relates to a water-sealed dust cleaning structure for a sintering ring cooler, belonging to the technical field of general cleaning facilities. Background Art
[0002] The hot sintered ore discharged from the sintering machine enters the feeding chute after single roller crushing, and is continuously and evenly distributed on the plate layer of the rotary trolley of the ring cooler by the feeding chute. The rotary trolley makes horizontal circular motion through the circular track under its rotary frame; at the same time, the blast system sends cold air into the bellows under the trolley. Under the action of positive pressure, the cold air enters through the gap between the plate layers of the trolley to exchange heat with the hot sintered ore layer. After becoming hot air, it is released through the chimney or enters the waste heat utilization system from the ring cooling hood on the top surface of the material layer, so that the sintered ore can be cooled. The water seal tank and sealing device are located directly below the rotary trolley, and are composed of an annular tank body, a sealing plate, and end seals. End seals are provided at both ends of the water seal tank and the sealing device, and a partition is provided in the middle. The seal adopts high temperature resistant rubber seal.
[0003] During the operation of the annular cooler, due to seal failure or disrepair, a large amount of sintering ash accumulates on both sides of the plug plate of the lower water seal tank, especially on the inner side of the plug plate. The sintering ash is hardened into blocks after being in contact with water for a long time, resulting in the increasing friction between the plug plate and the sintering ash blocks. The lower water seal tank is a ring design with a circumference of 150 meters. There are three sedimentation tanks designed in the lower water seal tank. The water in the lower water seal tank is only replenished according to the water level. The water itself does not circulate. The scraper plate in the lower water seal tank rotates with the trolley to transport the accumulated material at the bottom of the lower water seal tank to the sedimentation tank. Since the scraper plate has a long travel distance and runs slowly, it is impossible to scrape all the sludge to the sedimentation tank. The accumulated material is finally deposited and hardened, causing the scraper plate to fall off because it cannot scrape the hardened sintering ash, and even causing the annular cooler to shut down, seriously affecting the normal sintering production. Summary of the invention
[0004] The technical problem to be solved by the present invention is to clean up the sintering ash inside the plug plate of the lower water seal groove of the ring cooler in time.
[0005] The technical solution proposed by the present invention to solve the above technical problems is: a ash cleaning structure of the lower water seal groove of a sintering ring cooler, wherein a lower plug plate is arranged in the lower water seal groove, the top of the lower plug plate is fixed to the bottom of the rotary trolley of the ring cooler, a pair of horizontally spaced support plates are arranged on the inner side wall of the lower plug plate, a vertical rotating shaft is arranged through the pair of support plates, a gear located in a horizontal state between the pair of support plates is arranged near the top of the rotating shaft, a rack meshing with the gear is arranged on the circumferential inner side wall of the lower water seal groove, and the rotating shaft passes through a pair of A bottom milling cutter is installed at the bottom end downward behind the support plate, and a first bevel gear sleeved on the rotating shaft is installed on the upper part of the bottom milling cutter, and a bottom bearing and a bottom bearing seat are installed at the lower end of the rotating shaft. A short shaft is fixed on the bottom bearing seat on the side facing the inner side of the circumference of the lower water seal groove, and a side milling cutter is installed at the protruding end of the short shaft, and a second bevel gear sleeved on the short shaft is installed on the side milling cutter, and the first bevel gear is meshed with the second bevel gear, and the bottom milling cutter is close to the inner bottom wall of the lower water seal groove, and the side milling cutter is close to the inner side wall of the circumference of the lower water seal groove.
[0006] Furthermore, an opening for the high-pressure water gun to enter and exit is provided on the lower insert plate, and an inclined scraper is installed at the opening of the lower insert plate, and the inclined scraper extends to the inner side of the circumference of the lower water seal groove.
[0007] The beneficial effect of the present invention is that a bottom milling cutter and a side milling cutter are installed between the lower plug plate in the lower water seal groove and the inner side of the lower water seal groove, and the power of the lower plug plate rotating with the ring cooler rotary trolley is cleverly lent to the bottom milling cutter and the side milling cutter through the specially designed gear rack and rotating shaft, so that the dust accumulated on the lower plug plate in the lower water seal groove and the inner side of the lower water seal groove can be cleaned out in time. In addition, an opening is provided on the lower plug plate, and the dust accumulated on the lower plug plate and the inner side of the lower water seal groove can be washed by a manual high-pressure water gun; and an inwardly inclined scraper is installed at the opening of the lower plug plate, and the power of the lower plug plate rotating with the ring cooler rotary trolley can be further used to make the inclined scraper further clean the dust accumulated on the lower plug plate and the inner side of the lower water seal groove.
