Description

Technical Field

[0001] This utility model relates to the field of metallurgy, and in particular to a feeding grate for a sintering batching chamber in sintering production. Background Technology

[0002] Sintering is the process of reducing iron ore, auxiliary materials, and fuel at high temperatures to produce a finished product rich in elements such as iron, silicon, calcium, and magnesium, namely sintered ore. Sintered ore is of excellent quality, possessing high mechanical properties and certain chemical reactivity.

[0003] In the sintering production process, the small scale in the batching chamber is a key piece of equipment for accurately weighing various raw materials. The feeding process of the small scale directly affects the accuracy of batching and production efficiency. Currently, traditional feeding grates have the following problems: unreasonable screen size settings lead to uneven feeding, easily causing material accumulation or blockage; poor ability to separate impurities other than raw materials, affecting the mixing and granulation of subsequent processes; and impurities screened out by the grate are inconvenient to discharge. These problems seriously affect the stability of sintering batching and production efficiency, therefore, an improved feeding grate is needed to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a sintering batching chamber feeding grate for sintering production in order to solve the above-mentioned problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

A fixed frame is rotatably connected to the front end of the grate body, and the fixed frame is fixedly connected to the front support rod. A slag discharge plate is fixedly connected to the front end of the fixed frame, located between two adjacent support rods. A vibration motor is fixedly connected to one side of the grate body, and a flipping mechanism is arranged on the other side of the grate body. The flipping mechanism includes a bracket, which is fixedly connected to the support rod. A rotating shaft is rotatably connected inside the bracket. A push plate is fixedly connected to the side of the rotating shaft closest to the grate body. A power mechanism for driving the rotating shaft to rotate is provided on the bracket. The push plate has an isosceles trapezoidal cross-section. A locking mechanism is fixedly provided on the rear side of the grate body, and a locking mechanism is fixedly provided on the rear support rod, located below the locking mechanism.

[0007] Preferably, the sieve holes of the main body of the grate are square, the main body of the grate has a size of 1.2m*0.8m, and the size of the sieve holes is 0.1m*0.1m.

Therefore, they should not be construed as limitations on this utility model.

[0025] The present invention will be further described below with reference to the accompanying drawings:

[0026] like Figures 1-7As shown, a sintering batching chamber feeding grate for sintering production includes a grate body 1. The screen holes of the grate body 1 are square. The dimensions of the grate body 1 are 1.2m * 0.8m, with a total area of ​​0.96㎡. The screen holes are 0.1m * 0.1m in size, totaling 96 screen holes. More screen holes can effectively block impurities, preventing them from flowing to the next process, ensuring the mixing and granulation of raw materials, and stabilizing the quality of the finished ore. Multiple support rods 2 are arranged on both the front and rear sides of the grate body 1. The support rods 2 are fixedly connected to the mixing belt frame 3. A fixing frame 101 is rotatably connected to the front end of the grate body 1. The fixing frame 101 is fixedly connected to the front support rods 2. A slag discharge plate 102 is fixedly connected to the front end of the fixing frame 101 by screws. The slag discharge plate 102 is located between two adjacent support rods 2. When the grate body 1 is flipped, its rear end lifts upwards, thus... The debris is discharged through the slag discharge plate 102. A vibration motor 103 is fixedly connected to one side of the grate body 1. The vibration motor 103 ensures that the raw materials fall evenly and prevents large pieces of material from clogging the discharge hole. In addition, it helps to discharge debris during the slag discharge process. A flipping mechanism 6 is arranged on the other side of the grate body 1. The flipping mechanism 6 includes a bracket 601, which is fixedly connected to the support rod 2. A rotating shaft 602 is rotatably connected inside the bracket 601. A push plate 603 is fixedly connected to the side of the rotating shaft 602 near the grate body 1. A power mechanism 7 for driving the rotating shaft 602 to rotate is provided on the bracket 601. The cross-section of the push plate 603 is an isosceles trapezoid, and the upper and lower surfaces of the push plate 603 are set as inclined surfaces. A snap-fit ​​mechanism 4 is fixedly provided on the rear side of the grate body 1. A locking mechanism 5 is fixedly provided on the support rod 2 on the rear side. The locking mechanism 5 is located below the snap-fit ​​mechanism 4.

[0027] The snap-fit ​​mechanism 4 includes a snap-fit ​​plate 401, which is connected to the rear side of the grate body 1 by screws. Multiple snap-fit ​​pins 402 are welded to the bottom of the snap-fit ​​plate 401, and snap-fit ​​holes 403 are provided on the snap-fit ​​pins 402.

[0028] Locking mechanism 5 includes locking plate 501, which is fixedly connected to the rear support rod 2. A movable rod 502 is slidably connected horizontally inside locking plate 501. One end of the movable rod 502 near bracket 601 extends out of locking plate 501, and push plate 603 can abut against the movable rod 502. A spring 503 is fixed between the other end of the movable rod 502 and the inner wall of locking plate 501. When push plate 603 rotates, it presses the movable rod 502 through its inclined surface, causing the movable rod 502 to retract into locking plate 501. Within 01, the spring 503 is compressed. When the locking plate 501 moves away from the movable rod 502, the spring 503 rebounds, causing the movable rod 502 to reset. The top of the locking plate 501 has multiple L-shaped locking slots 504. The locking pin 402 can extend into the locking slots 504. The top of the movable rod 502 is fixedly connected with multiple locking pins 505. The locking pins 505 can be inserted into the locking holes 403. In this way, the rear end of the grate body 1 can be locked together with the locking mechanism 5, preventing the rear end of the grate body 1 from moving.

[0029] The support rod 2 includes a steel pipe 201 and a reinforcing bar 202. The steel pipe 201 is 0.5m long and 0.05m in diameter. The distance from the grate body 1 to the mixing conveyor belt is required to be 0.3m or more. This distance can be adjusted according to the distance from the belt conveyor to the mixing conveyor belt, and is not limited here. The reinforcing bar 202 is set inside the steel pipe 201 and is fixedly connected to the mixing conveyor belt frame 3. The fixing frame 101, locking plate 501, and bracket 601 are all fixedly connected to the steel pipe 201. The diameter of the reinforcing bar 202 is 0.03m. The gap between the steel pipe 201 and the reinforcing bar 202 is filled with a rubber layer 203. The rubber layer 203 is made of wear-resistant rubber material and has a cushioning effect.

[0030] The power mechanism 7 includes a motor 701, which is bolted to the bracket 601. The output shaft of the motor 701 is fixedly connected to a worm gear 702, which meshes with a worm wheel 703, which is fixedly connected to the rotating shaft 602.

[0031] Working Principle: During use, raw materials are screened on the grate body 1. The vibrating motor 103 causes the grate body 1 to vibrate at a certain frequency, ensuring that the raw materials fall evenly on the grate body 1. After screening, the impurities on the grate body 1 need to be discharged. At this time, the motor 701 drives the worm gear 702 to rotate, the worm gear 702 drives the worm wheel 703 to rotate, the worm wheel 703 drives the rotating shaft 602 to rotate, and the rotating shaft 602 drives the push plate 603 to rotate. The rear end of the push plate 603 starts to rotate upward and first contacts the movable rod 502. The push plate 603 uses the inclined surface to squeeze the movable rod 502 into the locking plate 501. The spring 503 is compressed. When the movable rod 502 moves, it drives the locking pin 505 to move, so that the locking pin 505 is disengaged from the snap-fit ​​hole 403, releasing the lock on the snap-fit ​​pin 402. As the push plate 603 rotates, before the movable rod 502 returns to its original position, the push plate... Push plate 603 reaches the bottom of locking plate 401 and lifts locking plate 401 upward. When locking pin 402 disengages from locking groove 504, push plate 603 disengages from movable rod 502. Push plate 603 continues to rotate, causing locking plate 401 to drive the rear end of grate body 1 to flip upward. Grate body 1 tilts forward, allowing debris to be discharged through slag discharge plate 102. After the debris is discharged, push plate 603 reverses, and grate body 1 follows push plate 603 to reset under gravity. During the reset process, push plate 603 will press movable rod 502 again, allowing locking pin 402 to smoothly enter locking groove 504. Then push plate 603 disengages from movable rod 502 again, and spring 503 drives movable rod 502 and locking pin 505 to reset. Locking pin 505 is inserted into locking hole 403 again, completing the locking of grate body 1. The above process is repeated each time debris is emptied.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
