Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of adjustable material spreading boxes, in particular to an adjustable material spreading box. Background Art
[0002] The function of the spreading box is to allow the agglomerated materials to impact and disperse on the spreading plate when the materials enter the next-stage cyclone or decomposition furnace from the upper-stage preheater. On the one hand, dispersing the materials improves the heat exchange efficiency between the materials and the hot air flow; on the other hand, it prevents the materials from rushing downward in the form of high-kinetic energy agglomerates, blocking the feed pipeline and causing a preheater blockage accident.
[0003] When the spreading box is in use, the angle of the spreading plate is usually adjusted to improve the dispersion of materials during material discharge. Since some larger agglomerated materials are still not dispersed enough after impacting the spreading plate, their decomposition rate into the kiln will be reduced and coal consumption will increase when they fall to the next process. Therefore, an adjustable spreading box is proposed to address the above problems. Utility Model Content
[0004] The utility model aims to provide an adjustable material spreading box to solve the problem that the material is not dispersed enough to enter the next process, which will reduce the decomposition rate and increase the coal consumption.
[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] Preferably, one end of the rotating member passes through the material spreading box body, and the material spreading plate and the rotating member are fixedly connected.
[0008] Preferably, a second sponge layer is fixedly connected inside the protective frame and at the bottom of the spreading plate, and a sealing shell is provided on the outer side of the output shaft of the vibration motor.
[0009] Preferably, the spring is arranged between the vibration plate and the buffer layer, and the damping rods are arranged in a group of four below the vibration plate.
[0010] Preferably, a rubber layer is fixedly connected to the top of the vibration plate, and a plurality of anti-sliding blocks arranged in the form of arc-shaped protrusions are fixedly connected to the top of the rubber layer.
[0011] Compared with the prior art, the beneficial effects of the utility model are:
[0012] In the utility model, by providing a material spreading box body, a material feed port, a rotating part, a material spreading plate, holes, a vibration motor and a vibration plate, the material falls from the material feed port into the interior of the material spreading box body until it impacts the surface of the vibration plate, and the vibration motor drives the vibration plate to vibrate, so as to further disperse the material on the surface of the vibration plate, so that when it falls to the next process, the decomposition rate can be improved and the coal consumption can be reduced. By providing a damping rod and a spring between the vibration plate and the material spreading plate, the vibration plate has a shock-absorbing and buffering effect when vibrating above the material spreading plate. By providing a rubber layer on the top of the vibration plate, the friction between the vibration plate and the material is increased, so that the material is not easy to slide directly from the vibration plate to the next process. The process is characterized in that a plurality of arc-shaped raised anti-sliding blocks are arranged on the top of the rubber layer, so that the residence time of the material at the vibration plate is further increased, so that the material falls to the next process after being fully vibrated and dispersed. The sealing shell arranged in the protection frame increases the sealing effect at the vibration motor, so that the material is not easy to fall into the protection frame. The second sponge layer arranged in the protection frame and at the bottom of the spreading plate increases the protection effect of the vibration motor. Since the diameter of the hole opened at the spreading plate is slightly larger than the diameter of the output shaft of the vibration motor, the influence of the output shaft on the spreading plate during vibration is reduced. The first sponge layer and the buffer layer arranged on the top of the spreading plate make it difficult for the vibration plate to affect the spreading plate during vibration.

[0025] One end of the rotating member 3 passes through the main body 1 of the spreading box, and the spreading plate 4 is fixedly connected to the rotating member 3 to facilitate the rotation of the spreading plate 4; a second sponge layer 10 is fixedly connected inside the protective frame 9 and at the bottom of the spreading plate 4, and a sealing shell 11 is provided on the outer side of the output shaft of the vibration motor 8 to increase the sealing effect of the protective frame 9 and further protect the vibration motor 8; the spring 13 is arranged between the vibration plate 14 and the buffer layer 7, and the damping rods 12 are arranged in a group of four under the vibration plate 14 to increase the shock-absorbing effect of the spreading plate 4; a rubber layer 15 is fixedly connected to the top of the vibration plate 14, and a plurality of anti-sliding blocks 16 with arc-shaped protrusions are fixedly connected to the top of the rubber layer 15 to increase the time that the material stays on the vibration plate 14, thereby further improving the material decomposition rate.
[0026] Working process: During the operation of the equipment, the external power supply is energized. When the adjustable spreading box is in use, first place the spreading box body 1 in a suitable position, and the user rotates the rotating part 3 to adjust the angle of the spreading plate 4. The material falls from the discharge port of the upper preheater to the feed port 2 of the spreading box body 1. The agglomerated material impacts the surface of the vibration plate 14 for preliminary dispersion. The impact force and weight of the material drive the vibration plate 14 to move downward, and the damping rod 12 and the spring 13 play a shock-absorbing role. The first sponge layer 6 and the buffer layer 7 arranged on the surface of the spreading plate 4 reduce the impact of the material on the spreading plate 4. At this time, the vibration motor 8 is started, and the vibration of the vibration motor 8 drives the vibration plate 14 to be in a vibrating state, so as to further disperse the material on the surface of the vibration plate 14. Since the surface of the vibration plate 14 is provided with a function to increase the vibration, the vibration plate 14 is provided with a function to increase the vibration. The high-friction rubber layer 15 and the arc-shaped raised anti-sliding block 16 increase the residence time of the material on the surface of the vibration plate 14, so that it can be fully vibrated for dispersion processing. The sealing shell 11 arranged in the protective frame 9 increases the sealing effect at the vibration motor 8, so that the material is not easy to fall into the protective frame 9. The second sponge layer 10 arranged in the protective frame 9 and at the bottom of the spreading plate 4 increases the protection effect of the vibration motor 8. Since the diameter of the hole 5 opened at the spreading plate 4 is slightly larger than the diameter of the output shaft of the vibration motor 8, the influence of the output shaft of the vibration motor 8 on the spreading plate 4 during vibration can be reduced. The vibration device arranged on the top of the spreading plate 4 further improves the decomposition rate of the material when it falls to the next process, reduces coal consumption, and the shock-absorbing device and protective device are arranged to reduce the influence of the vibration device on the spreading plate 4 during vibration.
