As shown in fig. 1 to 3, a storage bin for controlling a steel slag discharging speed comprises a storage bin body 10, a baffle rotating device, a steel slag weight detecting device, a rotor blade rotating device and a control cabinet 50.
The storage bin body 10 comprises a storage chamber 11, a funnel chamber 12 and a discharge chamber 13 which are coaxially arranged in sequence from bottom to top.
The baffle rotating device comprises a left baffle 21, a right baffle 22, a left baffle driving device and a right baffle driving device; the left side of the left baffle plate 21 is rotatably arranged on the side wall of the bottom of the storage chamber 11 and can be driven by a left baffle plate driving device to rotate; the right side of the right baffle 22 is rotatably arranged on the side wall of the bottom of the storage chamber 11 and can be driven by a right baffle driving device to rotate; preferably, the rotation angle of the left baffle 21 and the right baffle 22 from the horizontal plane downward is 0 ° to 45 °. The sum of the lengths of the left baffle 21 and the right baffle 22 is equal to the diameter of the storage chamber 11; preferably, the length of both the left baffle 21 and the right baffle 22 is one half the diameter of the storage chamber 11. When the left baffle 21 and the right baffle 22 rotate to the same plane, the left baffle 21 contacts with the right baffle 22, and the left baffle 21 and the right baffle 22 after contact form a cross section of the storage chamber 11. Preferably, the left side of the left baffle plate 21 is at a height from the bottom of the storage chamber 11 not less than the length of the left baffle plate 21The right side of the right baffle 22 is at a height from the bottom of the storage chamber 11 not less than +.>。
The steel slag weight detection device comprises a left weight sensor 31 and a right weight sensor 32; the left weight sensor 31 is disposed on the left side inner sidewall of the funnel chamber 12 and located right below the left baffle 21, corresponding to the opening of the right baffle 22; the right weight sensor 32 is provided on the right side inner wall of the hopper chamber 12 and is located directly below the right barrier 22, corresponding to the opening of the left barrier 21. The weight sensor transmits the numerical value to the control cabinet 50 by sensing the weight, and the control cabinet 50 automatically controls the rotation angle of the baffle plate, and the heavier the baffle plate, the smaller the angle between the baffle plate and the horizontal plane. The situation that a large amount of steel slag falls together sometimes happens, at the moment, the weight displayed by the weight sensor is overweight, the angle of the baffle is automatically adjusted by the control cabinet 50, so that the rotation angle of the baffle and the horizontal plane is reduced until the weight of the weight sensor reaches the set range, and at the moment, the angle of the baffle is restored to the original angle.
The turning vane rotating means includes a turning vane 41 and turning vane driving means; the rotating blades 41 are arranged in the discharging chamber 13, preferably, the rotating blades 41 are in a cross shape, the speed of the rotating blades 41 can be adjusted, and the rotating speed of the rotating blades 41 is 30-60r/min; the rotor blade driving means is connected to the rotor blade 41.

In the non-blanking state, the left baffle 21 and the right baffle 22 are horizontally arranged and are used for storing steel slag in the storage bin. In the blanking state, the left baffle 21 and the right baffle 22 are rotated downward, and the steel slag falls therefrom through the hopper chamber 12. If too much steel slag falls on the weight sensor, a bearing weight value of the weight sensor is set at the moment, and the rotation angle of the baffle is controlled according to the bearing weight value so as to intelligently control the steel slag discharging amount. In the case where only one side of the baffle is opened, the left baffle 21 is taken as an example, and when the left baffle 21 is first opened, the steel slag falls from the left baffle 21 onto the right weight sensor 32, and when the right weight sensor 32 exceeds the received weight value, the rotation angle of the left baffle 21 is reduced. If there is less steel slag falling, the steel slag does not accumulate in the hopper chamber 12 and falls directly from the discharge chamber 13 into the bucket elevator through the turning vanes 41.
Taking 90t of steel slag stored in a storage bin as an example, the maximum load of a bucket elevator is 30 t/h. Before screening, the drum screen and the bucket elevator are opened in sequence to enable the drum screen and the bucket elevator to operate normally, and then the rotating speed of the rotating blades 41 is set to be 50r/min, and a switch is started. Finally, the left baffle and the right baffle are controlled to be slowly opened from 0 degrees, the reading change of the left weight sensor and the right weight sensor is observed, in order to ensure that the steel slag at the outlet of the storage bin can be discharged in time, the rotary blades are prevented from being blocked by a large amount of steel slag which falls instantaneously, and when the reading addition of the left weight sensor and the right weight sensor is controlled to be 9kg-10kg, the rotation of the left baffle and the right baffle is stopped, and the rotation angle is kept at the moment. At the moment, the maximum discharging amount of the storage bin is 10kg/r, the maximum discharging amount is matched with the maximum load of the bucket elevator, and all steel slag in the storage bin can be screened out only for 3 hours at the highest speed, so that the efficiency is highest. After screening the steel slag, the left and right baffles are rotated first, reset, and then the rotating blades 41, the bucket elevator and the drum screen are sequentially closed.
The utility model mainly solves the problem of blockage in the blanking process of the steel slag in the blanking bin, the rotation angle of the right baffle 22 is controlled by the left weight sensor 31, the steel slag blanking amount is intelligently controlled by the rotation angle of the left baffle 21 is controlled by the right weight sensor 32, the steel slag discharging amount is further controlled by combining the rotation speed of the rotating blade 41 at the outlet, the equipment is convenient to reform and simple to operate, and the normal operation of the steel slag screening system can be realized by matching different power bucket elevators.
After transformation, the storage bin changes the steel slag discharging speed through twice adjustment, if a bucket elevator has problems in the steel slag screening process, the left baffle plate, the right baffle plate and the rotating blades 41 can be quickly closed to reset, and the steel slag is continuously put into use after the problems are solved, so that no secondary damage is caused. After the problem occurs in the bucket elevator, the original gate valve is free of any valve at the outlet, and even if the gate valve is closed rapidly, a large amount of steel slag at the lower part of the storage bin can directly fall into the bucket elevator, and after the problem is treated, the steel slag in the bucket elevator needs to be cleaned, so that time and labor are wasted.
