Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of anti-spraying structure for cold ash machines, and in particular to an anti-spraying structure for cold ash machines. Background Technology
[0002] Currently, the structure of cold ash feeder systems in the domestic thermal power, heating, and new materials industries mainly uses the simplest manual slide gate valve with a reducer at the cold ash feeder inlet. A pressure plate is placed on the reducer, and the boiler feed pipe extends downwards through the pressure plate on the reducer to allow for free expansion in all directions. However, with the development and upgrading of coal-fired boilers, the materials discharged from the boilers are becoming increasingly fine. These fine materials are also lighter in density. When the material is discharged from the boiler feed pipe and reaches the cold ash feeder for cooling, it first passes through the simple manual slide gate valve. Fine ash leaks out through the gaps around the valve plate. When the material reaches the pressure plate of the reducer, fine ash leaks out from the boiler feed pipe through the pressure plate and the junction of the pressure plate and the reducer. This leakage is particularly severe when the boiler is unstable, causing significant dust pollution on site and a relatively large environmental impact.
[0003] Therefore, those skilled in the art have provided an anti-spraying structure for a cold ash machine to solve the problems mentioned in the background art. Utility Model Content

[0028] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.
[0029] Please refer to Figure 1-4 A spray-proof structure for a cold ash machine includes a cold ash machine feed pipe 1 and a flange 2. A three-dimensional compensation expander 3 is installed at the top of the cold ash machine feed pipe 1, and a boiler feed pipe 4 is installed at the top of the three-dimensional compensation expander 3. The cold ash machine feed pipe 1, the three-dimensional compensation expander 3, and the boiler feed pipe 4 are all sealed and connected through the flange 2. A drive box 5 is installed on the right side of the three-dimensional compensation expander 3. A rotary motor 6 is installed inside the drive box 5. A turntable 7 is fixedly connected to the output end of the rotary motor 6. A drive column 8 is fixedly connected to the right side of the front of the turntable 7. A drive frame 9 is slidably connected to the outer surface of the drive column 8. A drive plate 10 is fixedly connected to the left side of the drive frame 9. One end of the drive plate 10 passes through the drive box 5 and is fixedly connected to a reinforcing plate 11. A striking plate 12 that works with the three-dimensional compensation expander 3 is fixedly connected to the left side of the reinforcing plate 11.
[0030] In this embodiment: By setting up a cold ash machine feed pipe 1, flange 2, three-dimensional compensating expander 3, and boiler feed pipe 4, the present invention can achieve a fully enclosed conveying state, preventing material leakage. By setting up a drive box 5, rotary motor 6, turntable 7, drive column 8, drive frame 9, drive plate 10, reinforcing plate 11, and striking plate 12, the three-dimensional compensating expander 3 can be struck to achieve the effect of vibration descaling. By setting up the above structure, dust leakage can be avoided when the cold ash machine is feeding, and the three-dimensional compensating expander 3 can be vibrated to descaling, thereby effectively avoiding dust pollution and reducing the maintenance frequency of the three-dimensional compensating expander 3.
[0031] The outer surface of the boiler feed pipe 4 is provided with a fully enclosed manual discharge valve 13. The fully enclosed manual discharge valve 13 is welded to the connection of the boiler feed pipe 4. The top and bottom of the drive frame 9 are fixedly connected with guide plates 14. The top and bottom of the inner cavity of the drive box 5 are provided with guide grooves 15 that cooperate with the guide plates 14. The outer surface of the guide plates 14 is slidably connected to the inner surface of the guide grooves 15. The left side of the drive box 5 is embedded with a sliding frame 16. The inner surface of the sliding frame 16 is slidably connected to the outer surface of the drive plate 10. The bottom of the rotary motor 6 is fixedly connected with a mounting plate 17. The right end of the mounting plate 17 is fixedly connected to the connection of the drive box 5. The front of the drive box 5 is fixedly installed with a maintenance plate by screws. The upper and lower positions of the left side of the inner cavity of the drive box 5 are both bonded with buffer pads. The top and bottom left sides of the drive box 5 are fixedly connected with brackets 18. One end of the two brackets 18 is fixedly connected to the connection of the cold ash machine feed pipe 1 and the boiler feed pipe 4, respectively.
[0032] The implementation principle of this utility model is as follows: In use, the boiler feed pipe 4, the three-dimensional compensation expander 3 and the cold ash machine feed pipe 1 are sealed and connected by the flange 2. The three-dimensional compensation expander 3 can absorb the expansion from the upper, lower and left sides of the boiler. During the process of the boiler material being discharged from the boiler feed pipe 4 to the cold ash machine for cooling, all connection parts are connected by the flange 2, so that the entire ash discharge process can achieve a fully sealed conveying state, which has a very good effect on preventing material leakage.
[0033] When the inner wall of the three-dimensional compensation expander 3 accumulates a lot of dust during use, the operator periodically plugs in the rotary motor 6 and starts the external controller of the rotary motor 6. This causes the output end of the rotary motor 6 to drive the turntable 7 to rotate. The turntable 7 drives the drive column 8 to rotate and slide on the inner surface of the drive frame 9, pushing the drive frame 9 to move back and forth. At the same time, the drive frame 9 drives the drive plate 10 to move back and forth, and the drive plate 10 drives the reinforcing plate 11 to move back and forth. This causes the reinforcing plate 11 to drive the striking plate 12 to move back and forth repeatedly, striking the outer shell of the three-dimensional compensation expander 3. The energy of the vibration waves causes the scale layer on the inner wall of the three-dimensional compensation expander 3 to loosen and fall off, thereby achieving a cleaning effect. At the same time, the vibration descaling method will not damage the metal surface. The device is simple to operate and easy to use in a sealed environment, thus effectively preventing dust leakage. It also achieves the effect of vibration descaling of the three-dimensional compensation expander 3, effectively reducing the frequency of inspection and maintenance of the three-dimensional compensation expander 3.
[0034] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
