Technical Field
[0001] The utility model relates to the technical field of carbon black production auxiliary devices, in particular to a device for cleaning carbon black dust hanging on the wall of a bag filter cone hopper. Background Art
[0002] In the daily carbon black production process, the carbon black flue gas contains a large amount of water vapor after secondary rapid cooling. After these flue gases are filtered by the bag filter, the carbon black dust adheres to the filter bag, and the vibration of the filter bag causes the dust to fall into the cone bucket of the bag filter box. However, due to the large amount of water vapor, the carbon black particles stick to the inner wall of the cone bucket (wall hanging phenomenon), which leads to a decrease in the effectiveness of the bag filter, resulting in material accumulation and easy generation of impurities. In addition, serious accumulation of carbon black sticking to the inner wall of the cone bucket will cause excessive pressure in the equipment, affecting the entry of materials, affecting the performance of the device production capacity, and generating impurities that affect the quality of carbon black. In view of this, in-depth research on the above issues has led to the creation of this case. Utility Model Content

[0016] Example: In conjunction with the specification Figure 1-3It can be seen that in order to solve the problem of carbon black particles clumping on the wall of the carbon black bag filter cone bucket due to condensation of water vapor in the prior art, the present application specifically designs a bag filter cone bucket carbon black dust wall cleaning device, including a bag filter cone bucket body 1, a through hole is opened in a circular array along the side wall of the bag filter cone bucket body 1, an assembly connecting member is welded at the position of the through hole, one end of the assembly connecting member is connected to the pulse solenoid valve 2, the air inlet end of the pulse solenoid valve 2 is connected to the flexible hose 3, the lower end of the flexible hose 3 is connected to the air injection pipe 4 through a manual ball valve 11, One end of the gas injection pipe 4 is connected to the outlet end of the compressed air source 5; the above-mentioned assembly connection components include a fixing ring 6, a threaded seat 7 and a conversion joint 8. The fixing ring 6 is welded on the through hole position, the threaded seat 7 is welded on the exposed end of the fixing ring 6 and is located outside the bag filter cone bucket body 1. One end of the conversion joint 8 is threadedly matched with the threaded seat 7, and the other end is assembled and connected with the pulse solenoid valve 2, wherein the conversion joint 8 is a stainless steel double-headed external thread joint. During operation, each pulse solenoid valve 2 will purge the jet outlet within a range of about 2.4m in diameter. The high-pressure air provided by the compressed air source 5 can be pulse-jet-controlled by the pulse solenoid valve 2, thereby blowing the carbon black particles attached to the inner wall of the bag filter cone hopper body 1 through the jet outlet. The structure is simple and the degree of automation is high. In addition, the setting of the stainless steel double-headed male thread connector can further improve the adaptability of the device, improve the assembly efficiency, and facilitate the maintenance and replacement of the pulse solenoid valve 2. The device is installed and maintained from the outside of the equipment and can be easily installed on any equipment even at temperatures as high as 900°F. The maintenance workload is very small. It is mobile and can be shared with other carbon black lines, saving carbon black production costs. The workload of cleaning workers is greatly reduced and labor intensity is reduced. The cleaning time is short, and it does not affect the changes in carbon black production capacity and process parameters, thereby ensuring the stability of carbon black quality. It solves the problem of carbon black particles clinging to the wall of the carbon black bag filter cone hopper due to water vapor condensation, and can efficiently clean carbon black dust clinging to the wall of the bag filter cone hopper without affecting the normal production process.
