Technical Field

[0001] This utility model relates to the field of raw material storage technology, and in particular to a device for preventing blockage and clearing the discharge port of a fly ash raw material storage silo. Background Technology

[0002] Fly ash is a fine ash collected from the flue gas after coal combustion. Fly ash is the main solid waste discharged by coal-fired power plants. When fly ash is collected and recycled, it is stored in fly ash raw material silos. A fly ash raw material silo is a steel structure equipment used to store and transport powdery and granular materials. It is usually composed of a steel shell and an internal support structure. It is mainly used to store materials such as fly ash.

[0003] In existing raw material silos, fly ash is discharged from the discharge port during material discharge. Due to the high flow resistance between fly ash particles, blockages easily occur in the discharge port during material discharge, which affects the material discharge from the raw material silo. To address this issue, we propose a fly ash raw material silo discharge port anti-blockage and unblocking device. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a device for preventing and clearing blockages at the discharge port of a fly ash raw material silo.

The driving mechanism is equipped with a pushing mechanism inside, and a guiding mechanism is sleeved on the surface of the pushing mechanism.

[0007] Preferably, the driving mechanism includes a fixed frame, a fixed frame is fixedly connected to the lower part of the discharge port, and a drive motor is installed on the side of the fixed frame. The output end of the drive motor is connected to a drive shaft, and a push cam is sleeved on the surface of the drive shaft.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This device uses a drive motor to rotate the drive shaft and push the cam, which in turn drives the drive plate to move the push rod and the material pusher rod up and down along the discharge port. This reduces material blockage during the discharge process by pushing the material inside the discharge port.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figure 1-4 A device for preventing blockage and clearing the discharge port of a fly ash raw material silo includes a raw material silo body 1, a discharge port 2 connected to the bottom of the raw material silo body 1, and a driving mechanism 3 fixedly connected to the bottom of the discharge port 2. The driving mechanism 3 is equipped with a pushing mechanism 4 inside. The pushing mechanism 4 moves up and down along the discharge port 2 to reduce the blockage phenomenon in the discharge port 2. The surface of the pushing mechanism 4 is fitted with a guide mechanism 5.

[0026] Furthermore, refer to Figure 2 and Figure 3 It can be seen that the driving mechanism 3 includes a fixed frame 31. The fixed frame 31 is fixedly connected to the lower part of the discharge port 2, and a drive motor 33 is installed on the side of the fixed frame 31. The output end of the drive motor 33 is connected to the drive shaft 34, and a push cam 35 is sleeved on the surface of the drive shaft 34. The drive motor 33 can drive the drive shaft 34 to drive the push cam 35 to rotate in the fixed frame 31, which facilitates the function of the pusher mechanism 4. Since there are two push cams 35 symmetrically arranged on the surface of the drive shaft 34, the pushing effect can be improved.

[0027] Furthermore, refer to Figure 2 and Figure 3 It can be seen that the drive motor 33 is covered with a protective shell 32, and the protective shell 32 is connected to the surface of the discharge port 2 by bolts. The protective shell 32 can easily cover and protect the drive motor 33. At the same time, the protective shell 32 is connected to the fixing frame 31 by bolts, and the protective shell 32 can be disassembled and installed, which facilitates the maintenance of the drive motor 33.

[0028] Furthermore, refer to Figure 3 and Figure 4 It can be seen that the pushing mechanism 4 includes a driving plate 41, the surface of the pushing cam 35 abuts against the driving plate 41, and a pushing rod 42 is fixedly connected above the driving plate 41. A material-pulling rod 43 is fixedly attached to one end of the pushing rod 42 that passes through the discharge port 2. The discharge port 2 has a through hole that matches the pushing rod 42, so that the pushing rod 42 can move along the through hole, which facilitates the material-pulling rod 43 to move back and forth in the discharge port 2, reducing the blockage effect in the discharge port 2.

[0029] Furthermore, refer to Figure 4It can be seen that the cross-section of the driving plate 41 is set as rectangular, and guide rollers 44 are installed on all four sides of the driving plate 41. The inner wall of the fixed frame 31 is in contact with the surface of the guide rollers 44. Through the guide rollers 44 installed on the four sides of the driving plate 41, the guide rollers 44 can slide along the inner wall of the fixed frame 31 when the driving plate 41 moves, so as to limit and guide the driving plate 41.

[0030] Furthermore, refer to Figure 3 and Figure 4 It can be seen that the guide mechanism 5 includes a reset spring 51. The upper surface of the driving plate 41 is welded to the guide plate 52 through the reset spring 51. The side of the guide plate 52 is fixedly connected to a fixing post 53. The fixing post 53 is fixedly connected to the inner wall of the fixing frame 31. Through the elastic force of the reset spring 51, the driving plate 41 can be easily pushed to reset. The guide plate 52 can be fixed through the fixing post 53.

[0031] Furthermore, refer to Figure 3 and Figure 4 It can be seen that the guide plate 52 has a circular hole between it and the push rod 42. Through the circular hole in the guide plate 52, the push rod 42 can move along the circular hole, which serves to limit and guide the push rod 42. The return spring 51 is welded to the center of the drive plate 41 and the guide plate 52.

[0032] Working principle: When the raw material silo 1 is in use, according to the attached... Figure 1 Appendix Figure 2 Appendix Figure 3 and attached Figure 4 When discharging material, the drive motor 33 can drive the drive shaft 34 to drive the push cam 35 to rotate along the fixed frame 31. When the push cam 35 rotates, it can push the drive plate 41 and the guide roller 44 to move up and down along the fixed frame 31. As the drive plate 41 moves, the push rod 42 can drive the material-pulling rod 43 to move back and forth along the discharge port 2, which can poke the material inside the discharge port 2 and reduce blockage. At the same time, during the movement of the drive plate 41, the push rod 42 can slide along the guide plate 52 to play a guiding role. And through the elastic force of the return spring 51, the drive plate 41 can be easily pushed to reset.

[0033] The above is the complete working principle of this utility model.
