Description

Technical Field

[0001] The utility model relates to a slope sliding type closing cover for a steel slag hot stewing pool, belonging to the technical field of metallurgical equipment. Background Art

[0002] The steelmaking process produces large amounts of high-temperature liquid slag. This slag, after condensation, becomes solid waste, occupying significant space. Furthermore, the weathering of the slag into fine particles and dust easily contributes to air pollution. To achieve zero slag emissions, protect the ecological environment, and promote the development of a circular economy, steel companies typically discharge slag into slag simmering tanks, which are covered with a cap to prevent dust from forming.

[0003] Currently, the closures of steel slag hot simmering tanks are mostly hoisted to or removed from the top of the tank using an overhead crane. This not only occupies the crane, but also requires close cooperation from workers during the installation and removal process, which can easily lead to safety accidents. Some steel companies use hydraulic cylinders or electro-hydraulic cylinders to drive the hot simmering tank to open and close the closures. However, these devices require large driving forces and high motor power, and the service life of the hydraulic cylinders is significantly shortened in hot and humid environments, increasing equipment maintenance costs. Therefore, it is very necessary to improve the existing closures of steel slag hot simmering tanks. Utility Model Content

[0026] The utility model aims to provide a steel slag hot stewing pool closing cover in response to the defects of the prior art. The closing cover utilizes a winch to drive a sliding cover plate installed on an inclined slide rail. Since the inclined slide rail bears most of the dead weight of the closing cover, the winch only needs to provide a small traction force to drive the sliding cover plate to move, thereby completing the opening or closing action of the hot stewing pool. Compared with the closing cover of the traditional steel slag hot stewing pool, the driving power is greatly reduced. It has the advantages of simple structure, low cost, easy operation, high operating reliability, small footprint, and easy automation, which can save the purchase and maintenance costs of equipment. Moreover, the closing cover does not require close cooperation of workers during the opening or closing process, thereby eliminating potential accidents, ensuring the personal safety of operators, and has a broad application prospect.

[0027] See Figures 1-9 The utility model mainly includes a slope enclosure 1, a fixed cover plate 9, two slide rails 5, a sliding cover plate and a winch 4, wherein the sliding cover plate includes a lower sliding cover plate 2 and an upper sliding cover plate 3.

[0028] The slope enclosure 1 includes a rectangular front baffle 1-2 and two right-angled triangular side baffles 1-1. The front baffle 1-2 is vertically fixed to the front of the hot stewing pool 8, and the two side baffles 1-1 are symmetrically arranged on both sides of the hot stewing pool 8. The right-angled sides at the front end of each side baffle 1-1 are respectively connected to the two side edges of the front baffle 1-2, and the right-angled sides at the lower ends are fixed to the ground; the two slide rails 5 are respectively installed on the oblique sides of the upper parts of the two side baffles 1-1, and the two sides of the sliding cover are respectively slidably connected to the two slide rails 5, and the fixed cover 9 is located below the two slide rails 5. The front end of the fixed cover 9 is connected to the front baffle 1-2, and the two sides are respectively connected to the two side baffles 1-1. The winch 4 is fixed in front of the front baffle 1-2, and one end of the steel wire rope 7 wound on the drum of the winch 4 is connected to the sliding cover after passing through the pulley 6 at the top of the front baffle 1-2. When the sliding cover slides along the slide rails 5 to the upper position, it is located above the fixed cover 9, opening the slag hot simmering pool. When it slides to the lower position, it closes the slag hot simmering pool together with the fixed cover 9. The hoist 4 drives the sliding cover to slide along the slide rails 5 via the wire rope 7, moving the sliding cover to the upper or lower position, thereby opening or closing the slag hot simmering pool.

[0029] See Figure 1 、 Figure 7 and Figure 8Each slide rail 5 is equipped with an upper slideway 5-1 at the top and a lower slideway 5-2 at the bottom. Two sliding covers are provided: an upper sliding cover 3 and a lower sliding cover 2. Two upper cover rollers 15 are provided on either side of the upper sliding cover 3, and the upper cover rollers 15 are in rolling connection with the upper slideway 5-1. Two lower cover rollers 17 are provided on either side of the lower sliding cover 2, and the lower cover rollers 17 are in rolling connection with the lower slideway 5-2. An upper cover wheel stop 12 is fixed at the rear end of the upper slideway 5-1, corresponding to the upper cover rollers 15 at the rear of the upper sliding cover 3. The contact surface between the upper cover wheel stop 12 and the upper cover rollers 15 is an arcuate surface that matches the wheel rim of the upper cover rollers 15. This increases the contact area between the two and prevents damage to the upper cover rollers 15 due to excessive local stress. A lower cover wheel stop 13 is fixed in the middle and lower portion of the lower slideway 5-2, corresponding to the lower cover rollers 17 at the rear of the lower sliding cover 2. A pull ring 16 is fixed to the upper middle part of the front end of the upper sliding cover plate 3, and one end of the wire rope 7 on the drum of the hoist 4 is connected to the pull ring 16, which can drive the upper sliding cover plate 3 to move along the upper slide 5-1 through the pull ring 16; a drag column 18 corresponding to the front end surface of the upper sliding cover plate 3 is fixed to the upper middle part of the front end of the lower sliding cover plate 2. When the upper sliding cover plate 3 moves forward and upward along the upper slide 5-1, the drag column 18 can drive the lower sliding cover plate 2 to move forward and upward, and finally the upper sliding cover plate 3 and the lower sliding cover plate 2 are stacked on top of the fixed cover plate 9, thereby opening the hot stewing pool 8; the upper sliding cover plate 3 When moving downward and rearward along the upper slideway 5-1, the lower sliding cover plate 2 moves synchronously therewith. When the rear lower cover roller 17 of the lower sliding cover plate 2 moves to the position of the lower cover wheel block 13, the lower sliding cover plate 2 stops moving due to the blocking effect of the lower cover wheel block 13, and the upper sliding cover plate 3 continues to move downward and rearward. When the rear upper cover roller 15 of the upper sliding cover plate 3 moves to the position of the upper cover wheel block 12, the upper sliding cover plate 3 stops moving due to the blocking effect of the upper cover wheel block 12. At this time, the fixed cover plate 9, the lower sliding cover plate 2, and the upper sliding cover plate 3 each cover one-third of the hot stewing pool 8, thereby sealing the hot stewing pool 8. The structure of one section of fixed cover plate 9 plus two sections of sliding cover plates can maximize the opening of the hot stewing pool 8, making it convenient for overhead crane operation.

[0030] An upper proximity switch 10 corresponding to the front cover roller 15 of the upper sliding cover 3 is fixed to the front of the slide rail 5, and a lower proximity switch 11 corresponding to the rear cover roller 15 of the upper sliding cover 3 is fixed to the rear of the slide rail 5. The signal output ends of the upper proximity switch 10 and the lower proximity switch 11 are connected to the controller of the hoist 4. During the process of the upper sliding cover 3 moving forward and upward, when its front cover roller 15 moves to the position of the upper proximity switch 10, the controller of the hoist 4 stops the hoist 4 to prevent the lower sliding cover 2 and the upper sliding cover 3 from moving too far forward and upward and hitting the pulley 6. During the process of the upper sliding cover 3 moving backward and downward, when its rear cover roller 15 moves to the position of the lower proximity switch 11, the controller of the hoist 4 stops the hoist 4.

[0031] A dust removal duct interface 14 is provided on the front baffle 1 - 2 for connecting the dust removal duct.

[0032] The slope enclosure 1 is welded from a steel structure. The slide rail 5, fixed cover plate 9, and dust removal duct interface 14 are all welded to the slope enclosure 1; the lower cover wheel block 13 and the upper cover wheel block 12 are fixedly connected to the slide rail 5 by bolts; the upper proximity switch 10 and the lower proximity switch 11 are fixedly connected to the slide rail 5 by bolts. When the upper cover roller 15 approaches, the upper proximity switch 10 and the lower proximity switch 11 are triggered. The slide rail 5 is arranged at an angle to facilitate the winch 4 to pull the sliding cover plate back and forth through the wire rope 7; the fixed cover plate 9 is welded to the inside of the slope enclosure 1 to play a sealing role; the lower cover wheel block 13 and the upper cover wheel block 12 not only play a positioning role for the sliding cover plate, but also when the winch 4 fails, the lower cover wheel block 13 and the upper cover wheel block 12 can prevent the corresponding sliding cover plate from sliding down and out of the working area, playing a protective role.

[0033] The lower sliding cover plate 2 is welded with a steel structure. There are roller connection holes on both sides of the lower sliding cover plate 2. Four lower cover rollers 17 are connected to the lower sliding cover plate 2 through shaft holes and are evenly distributed on the outside of the lower sliding cover plate 2.

[0034] The structure of the upper sliding cover plate 3 is the same as that of the lower sliding cover plate 2. When the steel slag hot stewing pool 8 is being cleaned or dumped, the hot stewing pool 8 needs to be opened. At this time, the upper sliding cover plate 3 first moves obliquely upward on the slide rail 5. During the oblique upward movement, the upper sliding cover plate 3 contacts the dragging column 18 on the lower sliding cover plate 2, and drives the lower sliding cover plate 2 to move obliquely upward together until the upper proximity switch 10 is triggered and the car stops. At this time, the hot stewing pool 8 is in an open state.

[0035] When the slag hot stewing pool 8 is completed with slag cleaning or slag dumping, the hot stewing pool 8 needs to be closed. At this time, the winch 4 starts to lower the rope, and the upper sliding cover 3 and the lower sliding cover 2 move obliquely downward together by relying on their own gravity. After the lower sliding cover 2 reaches the position, the lower cover roller 17 is blocked by the lower cover wheel block 13. At this time, the lower sliding cover 2 stops moving, and the upper sliding cover 3 continues to slide obliquely downward. When the upper sliding cover 3 reaches the position, the upper cover roller 15 is blocked by the upper cover wheel block 12. At this time, the upper sliding cover 3 stops moving, and at the same time, the upper cover roller 15 triggers the lower proximity switch 11, and the winch 4 stops working. At this time, the hot stewing pool 8 is in a completely closed state.
