Detailed Description
The following refers to the drawings and describes an anti-blocking coal inlet three-way baffle device provided by the embodiment of the invention.
Example (b): as shown in figure 1, the device comprises a three-way baffle and a three-way baffle coal inlet channel, wherein the three-way baffle is positioned at a high-flow coal inlet point, and a coal inlet channel at the front end of the three-way baffle, particularly a bend angle, is easy to adhere coal to the wall of the coal inlet channel, so that the coal blockage phenomenon is caused by slow accumulation. If the raw coal is wet, the coal blockage event may be a family meal. And the three-way baffle and the coal inlet channel of the three-way baffle adopt a sealing form to avoid raw coal leakage, so that the difficulty in cleaning the coal blockage is increased. The induction mechanism comprises a coal plugging baffle plate 1 and a rotary limiting stopper 2, wherein one end of the coal plugging baffle plate is connected with the rotary limiting stopper, and the rotary limiting stopper is switched into a coal channel by swinging the coal plugging baffle plate 1. The coal blocking baffle 1 changes the coal feeding direction for the process requirement, and a baffle is adopted to block a coal feeding port which does not need to feed coal, so that the other coal feeding port can feed coal. When the first rotation angle of the rotation limiter 2 when the coal plugging baffle plate 1 is rotated in place is 55 degrees, and when the coal plugging baffle plate 1 is pressed by the flow of coal, the rotation limiter 2 rotates for the second time along with the pressing of the coal plugging baffle plate, and the second rotation angle is 60 degrees; after the coal plugging baffle 1 is subjected to reduction of coal inflow, the weight is reduced, the rotation limiter 2 recovers the first rotation angle of 55 degrees, and coal plugging information is sent to the data processing system. After the coal blocking baffle 1 is adjusted to the coal feeding direction, the stop stopper 2 is rotated to restart the induction mechanism, the coal blocking baffle is adjusted to 55 degrees, the coal blocking baffle is in a full-sealing state at 60 degrees, after the coal feeding flow impacts the coal blocking baffle, the coal blocking baffle 1 is moved to the full-sealing state at 60 degrees under the impact force, a spring shaft is arranged between 55 degrees and 60 degrees, and the stop stopper 2 is rotated to induce smooth coal feeding at the moment. When the rotation limiter 2 senses that the coal inlet amount is reduced, the original rotation angle of the coal plugging baffle plate 1 is 60 degrees, the thrust of the spring shaft is applied, the rotation angle is adjusted to 55 degrees, and the rotation limiter 2 judges that the coal plugging phenomenon occurs.
The blockage clearing system of the device comprises a buffer mechanism 3 and a rapping mechanism 4. Because the coal blockage is formed by accumulation, the coal blockage has high density and hardness, the blockage removal efficiency is not high by means of mechanical brute force, and the machine can be damaged. Therefore, the buffering mechanism 3 of the device can ensure that the coal blockage can have a space, which is beneficial to blockage removal operation. The buffer mechanism 3 is arranged on one side of the coal inlet channel at the front end of the three-way baffle and comprises a pull rod and a movable top plate, the movable top plate is arranged on the outer side of the coal inlet channel in a movable area, the pull rod is connected with the movable top plate, and the movable top plate is pulled to move in the movable area. The square box body is arranged outside the normally blocked coal inlet channel side, the side of the side wall of the square box body is normally used as the side wall of the coal inlet channel, and after coal blockage, the side baffle plate which is used as the side wall of the coal inlet channel of the square box body is pulled to the outside through the pull rod, so that a buffer space is reserved, and the coal blockage can fall smoothly. The size of the square box body is the size of the side wall of the coal inlet channel, and the sides are divided into 5 CM. The square box body is a sealed space, and a sealing strip is arranged to prevent the pulled coal from leaking outside. After the buffer mechanism 3 pulls out the buffer space of the coal blockage, the rapping mechanism is started. The rapping mechanism 4 is different from a common method of mechanical striking, the rapping device 4 is arranged at the elbow of a coal inlet three-way baffle coal inlet channel, the rapping device 4 is a telescopic device, the telescopic device consists of a folding iron cylinder 14, a telescopic rod 11 is arranged in the folding iron cylinder 14, one end of the telescopic rod 11 is connected with the top end of the folding iron cylinder 14, and the folding iron cylinder 14 is pulled to move telescopically according to the telescopic rod 11. The top end of the rapper also comprises a rapper 15, and the power of the rapper 15 is 0.12KW, the exciting force is 1000, and the weight is 12 KG. The purpose of the blockage removing operation is to knock and loosen the blocked coal to the three-way baffle plate and enter required equipment. The rapper 15 on the rapper can effectively clear the coal blockage. When the folding iron cylinder 14 is stretched into the blocked coal by the telescopic rod 11 through the rapping device, the rapping device 15 starts to work, the high-speed motion of the vibration motor generates the periodic high-frequency vibration of the blocked coal, and due to the periodic motion of the rapping device, on one hand, the blocked coal is separated from the side wall of the coal inlet channel to eliminate the friction of the blocked coal on the side wall of the coal inlet channel, and on the other hand, the blocked coal is influenced by the internal friction and the acceleration and is in an unstable state, so that the internal friction and the gathering force of materials are effectively overcome to eliminate the relative stability among the blocked coal in the coal inlet channel, the blocked coal is smoothly scattered, and the blockage clearing operation is completed.
