Abstract
Description
Technical Field
[0001] The utility model relates to the field of dry dust removal and desulfurization equipment, in particular to a dust shunt and dispersion device. Background Technique
[0002] The principle of the dust dispersion device is to send the agglomerated or caked materials into the dispersion cavity through a screw feeder, and the materials are impacted and sheared by a high-speed rotating rotor to be crushed and restored. In the existing dispersion devices, large-particle dust may not be dispersed thoroughly during dispersion, resulting in deposition or component jamming, affecting subsequent operations, and it is very troublesome to repair. Content of the Utility Model
[0003] In order to overcome the deficiencies of the above-mentioned existing problems, the utility model provides a dust shunt and dispersion device.
[0004] The technical solution adopted by the utility model to solve its technical problems is: a dust shunt and dispersion device, including a housing. A feeding channel is arranged above the housing. A screw rod driven by a rotating motor is arranged in the feeding channel. A feeding port is opened above the feeding channel, and a discharging port is opened below the feeding channel. A U-shaped filtering channel is opened in the housing. One end of the U-shaped filtering channel is an inlet, and the other end is an outlet. The inlet of the U-shaped filtering channel is connected to the discharging port. The rotating motor drives the screw rod to push the dust entering from the feeding port to the discharging port and into the housing. Below the inlet of the U-shaped filtering channel, there is a dispersion fan blade, and below the dispersion fan blade, there is a rotating filter screen. On one side of the U-shaped filtering channel and the rotating filter screen, there is a shunt channel. At the inlet of the shunt channel, there is a scraper tangent to the surface of the rotating filter screen. The outlet of the shunt channel is connected to the inlet of the U-shaped filtering channel. A conveying fan is arranged outside the shunt channel. A negative pressure fan is arranged at the outlet of the U-shaped filtering channel. The dust moves along the U-shaped filtering channel under the action of the negative pressure fan. When large-particle dust cannot pass through the rotating filter screen and adheres to the surface of the rotating filter screen, the dust on the surface of the rotating filter screen is peeled off by the scraper and enters the shunt channel, and is conveyed to the upper part of the dispersion fan blade by the conveying fan for secondary dispersion.
[0005] Preferably, maintenance openings are arranged on both sides of the housing, which is convenient for operation when the dust shunt and dispersion device fails or needs regular inspection.
[0006] Preferably, the bottom of the shunt channel is arc-shaped, which is convenient for large-particle dust to move upward.
[0007] Preferably, a stirring device is arranged at the bottom of the U-shaped filtering channel, and stirring fan blades are arranged on the stirring device to prevent dust from accumulating at the bottom of the U-shaped filtering channel.
[0008] The beneficial effects of the present utility model are as follows: it can screen and divert dust, pass the large-particle dust that has not been thoroughly dispersed through, and transport it to the upper part of the dispersing fan blades by a conveying fan for secondary dispersion. In addition, maintenance openings are provided on both sides of the housing, which is convenient for operation when the dust diversion and dispersion device fails or needs regular inspection. The bottom of the diversion channel is arc-shaped, which is convenient for large-particle dust to move upward. A stirring device is provided at the bottom of the U-shaped filter channel to prevent dust from accumulating at the bottom. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] All features disclosed in this specification, or all steps in any disclosed method or process, except for mutually exclusive features and / or steps, can be combined in any manner.
[0013] Any feature disclosed in this specification (including any additional claims, abstract, and drawings), unless specifically stated, can be replaced by other equivalent or similar-purpose alternative features. That is, unless specifically stated, each feature is only an example of a series of equivalent or similar features.
[0014] Such as Figure 1As shown in the figure, a dust shunt and dispersion device includes a housing 1. Above the housing 1, there is a feeding channel 2. Inside the feeding channel 2, there is a screw rod 6 driven by a rotating motor 5. Above the feeding channel 2, there is a feeding port 3, and below the feeding channel 2, there is a discharging port 4. Inside the housing 1, there is a U-shaped filtering channel 12. One end of the U-shaped filtering channel 12 is the inlet, and the other end is the outlet. The inlet of the U-shaped filtering channel 12 is connected to the discharging port 4. The rotating motor 5 drives the screw rod 6 to push the dust entering from the feeding port 3 to the discharging port 4 and into the housing 1. Below the inlet of the U-shaped filtering channel 12, there is a dispersion fan blade 7, and below the dispersion fan blade 7, there is a rotating filter screen 8.

The outlet of the shunt channel 10 is connected to the inlet of the U-shaped filtering channel 12. Outside the shunt channel 10, there is a conveying fan 11. At the outlet of the U-shaped filtering channel 12, there is a negative pressure fan. Under the action of the negative pressure fan, the dust moves along the U-shaped filtering channel 12. When large particle dust that cannot pass through the rotating filter screen 8 adheres to the surface of the rotating filter screen 8, the dust on the surface of the rotating filter screen 8 is peeled off by the scraper 9 and enters the shunt channel 10, and is conveyed by the conveying fan 11 to the upper part of the dispersion fan blade 7 for secondary dispersion.

[0018] This design is ingenious. It can screen and shunt dust, convey the large particle dust that has not been thoroughly dispersed to the upper part of the dispersion fan blade through the conveying fan for secondary dispersion. In addition, there are maintenance openings on both sides of the housing, which is convenient for operation when the dust shunt and dispersion device fails or needs regular inspection. The bottom of the shunt channel is arc-shaped, which is convenient for large particle dust to move upward.
