Technical Field

[0001] The invention relates to the technical field of settling boxes, in particular to a blowing and suction ash settling box. Background Art

[0002] In the iron and steel metallurgical industry, a soot blowing and suction production line is usually required. The main function of the soot blowing production line is to blow and suck the oxide layer on the inner surface of the steel pipe, and discharge the waste after three-stage filtration through the sedimentation box-cyclone dust collector-cartridge filter.

[0003] However, the existing sedimentation boxes have the disadvantages of small size, poor sedimentation effect, and easy clogging of the ash discharge port. They cannot completely filter large impurities such as sawdust and iron ears. Once large iron ears enter the subsequent filtration system, they will have a huge impact on the service life and filtration accuracy of the cyclone dust collector and the cartridge filter. For this reason, we propose a blowing and suction ash sedimentation box. Summary of the invention

[0020] Among them, the centrifugal fan 4 can move the gas input by the first air inlet pipe 5 on the inner wall of the collecting box 1 and the discharge cone 2, and descend due to internal swirl and gravity, so as to ensure the normal discharge of the ash material. The speed reduction belt 8 arranged inside the discharge cone 2 can reduce the operating speed inside the discharge cone 2 without affecting the effective collection of dust, thereby reducing the wear of the discharge cone 2. When the gas enters, the blocking mechanism 6 can be used to effectively filter large impurities such as sawdust and iron ears to prevent large impurities from entering and affecting subsequent processing. The large impurities after blocking can be collected through the collecting mechanism 7 to prevent the presence of large impurities from affecting the sedimentation effect.

One end of the collecting mechanism 7 is fixedly connected to the delivery pipe 9. Blocking rings 10 are provided inside the first air inlet pipe 5 and the delivery pipe 9. A filter fence 11 is provided between the two sets of blocking rings 10. The first air inlet pipe 5 and the delivery pipe 9 are fixedly connected by a locking screw.

[0022] Among them, when air is taken in, the first air inlet pipe 5 and the delivery pipe 9 are connected to each other by using a locking screw, and the filter fence 11 is clamped between the blocking ring 10 between the first air inlet pipe 5 and the delivery pipe 9, so that the filter fence 11 can be used to effectively block large impurities such as sawdust and iron ears, and large impurities such as sawdust and iron ears can be retained inside the collection mechanism 7.

[0023] See also Figure 1 , Figure 2 and Figure 4The collecting mechanism 7 includes a collecting pipe 12, a second air inlet pipe 13 and a discharge port 14.

The bottom of the collecting pipe 12 is inclined, and a discharge port 14 is opened on one side of the bottom of the collecting pipe 12.

[0024] The second air inlet pipe 13 can allow the gas to be discharged to the first air inlet pipe 5 and the inside of the collecting box 1 through the collecting pipe 12 and the conveying pipe 9, while the large impurities blocked by the blocking mechanism 6 can be discharged through the discharge port 14.

[0025] See also Figure 1 , Figure 2 , Figure 4 and Figure 5 The collecting mechanism 7 also includes a rotating shaft 15, a collecting bucket 16, a containing groove 17 and a driving motor 18. The collecting bucket 16 is rotatably connected to the collecting tube 12 at a position corresponding to the discharge port 14 through the rotating shaft 15. The collecting bucket 16 is provided with a containing groove 17. A driving motor 18 is fixedly installed on one side of the collecting tube 12, and the output end of the driving motor 18 is fixedly connected to the rotating shaft 15.

[0026] Among them, the large impurities blocked by the blocking mechanism 6 will be discharged into the containing groove 17 opened on the collecting barrel 16 through the collecting pipe 12 with an inclined bottom, and then the driving motor 18 will be operated, and the driving motor 18 will drive the rotating shaft 15 and the collecting barrel 16 to rotate, so that the large impurities inside the containing groove 17 can be discharged centrally through the discharge port 14.

[0027] See also Figure 1 and Figure 2 The outside of the collecting box 1 is fixedly installed with a mounting frame 19, and the outside of the mounting frame 19 is fixedly installed with multiple groups of positioning plates 20 overlapped on the top of the supporting frame 3. The positioning plates 20 and the supporting frame 3 are connected by locking bolts 21.

[0028] When the collection box 1 is installed, it is installed on the support frame 3 using the installation frame 19 , the positioning plate 20 and the locking bolts 21 . This installation method is convenient for disassembly and maintenance of the collection box 1 .

[0030] The working principle of the present invention is as follows: when in use, first, the centrifugal fan 4 can move the gas input by the first air inlet pipe 5 on the inner wall of the collecting box 1 and the discharge cone pipe 2, and descend due to internal swirl and gravity, so as to ensure the normal discharge of the ash material, and the speed reduction belt 8 arranged inside the discharge cone pipe 2 can reduce the operating speed in the discharge cone pipe 2 without affecting the effective collection of dust, thereby reducing the wear of the discharge cone pipe 2, and when the gas enters, the blocking mechanism 6 can be used to effectively filter large impurities such as sawdust and iron ears to prevent large impurities from entering and affecting subsequent processing, and the large impurities after blocking can be collected through the collecting mechanism 7 to prevent the presence of large impurities from affecting the sedimentation effect, and when the air is inhaled, the first air inlet pipe 5 and the conveying pipe 9 are connected to each other by a locking screw, and the filter fence 11 arranged will be clamped on the blocking ring 10 between the first air inlet pipe 5 and the conveying pipe 9. In this way, the filter fence 11 can be used to effectively block large impurities such as sawdust and iron ears, and large impurities such as sawdust and iron ears can be retained inside the collecting mechanism 7.
