[0025] This embodiment provides a dust recovery and treatment device for conveying granular raw materials through pipelines. Figure 1 and Figure 2 , including: a particle raw material conveying pipeline 1, a first blowing pipe 2, a dust removal pipe 3, a first blower 4, a dust collector 5, a second blowing pipe 6 and a second blower 7.

[0026] The particle raw material conveying pipeline 1 is arranged vertically; the first blowing pipe 2 and the dust removal pipe 3 are respectively installed horizontally on both sides of the particle raw material conveying pipeline 1 and are respectively connected to the particle raw material conveying pipeline 1; the first blower 4 is installed at the end of the first blowing pipe 2, and the first blowing pipe 2 and the dust removal pipe 3 are located at the same level; the dust collector 5 is installed at the end of the dust removal pipe 3; the second blowing pipe 6 is installed obliquely below the dust removal pipe 3 and is connected to the dust removal pipe 3, and the end of the second blowing pipe 6 extends in a direction away from the end of the dust removal pipe 3; the second blower 7 is installed at the end of the second blowing pipe 6.

[0027] When the dust recovery and processing device for conveying dust of the granular raw material pipeline of this embodiment is used for dust removal of granular raw material; the granular raw material enters and falls from the top of the vertically arranged granular raw material conveying pipeline 1, and the first blower 4 generates a horizontal airflow through the first blowing pipe 2, and uses the specific gravity difference between the granular raw material and the dust to blow the dust toward the dust removal pipe 3; at the same time, the second blower 7 generates an inclined airflow toward the end of the dust removal pipe 3 through the second blowing pipe 6, and the dust is blown to the dust collector 5 at the end of the dust removal pipe 3 for recovery through the combined action of the two airflows.

[0028] In this embodiment, the first blowing pipe 2 and the dust removal pipe 3 are respectively installed horizontally on both sides of the middle part of the particle raw material conveying pipeline 1, and the first blowing pipe 2 and the dust removal pipe 3 are located on the same horizontal line, and the diameter of the first blowing pipe 2 and the dust removal pipe 3 is the same as the diameter of the particle raw material conveying pipeline 1.

[0029] In this embodiment, a filter screen (not shown) is provided between the dust removal pipe 3 and the second blowing pipe 6, that is, at the connecting port of the dust removal pipe 3 and the second blowing pipe 6. By providing the filter screen, dust can be prevented from entering the second blowing pipe 6, and at the same time, the dust on the filter screen can be blown away by the action of the second blower, thereby reducing the dust adhesion on the filter screen and preventing the filter screen from being blocked.

[0030] In this embodiment, in order to facilitate the installation of the horizontally blowing second hair dryer 7 and the end of the second blowing pipe 6, a transverse section 61 is designed at the end of the second blowing pipe 6, thereby facilitating the installation of the second hair dryer 7 at the end of the second blowing pipe 6.

[0031] In this embodiment, the dust collector 5 is vertically arranged, and the dust removal pipe 3 is horizontally arranged. In order to install the vertically arranged dust collector 5 with the end of the dust removal pipe 3, a vertical connecting pipe 51 is arranged on the dust collector 5, which is respectively connected to the end of the horizontal dust removal pipe 3 and the dust collector 5.

[0032] In the present embodiment, the dust collector is a dust removal bag. In other embodiments, a powder collecting hopper may also be used.

[0036] The specific working process of the dust recovery and treatment device for conveying the granular raw material through the pipeline of this embodiment is as follows:

[0037] The controller controls the first blower 4 and the second blower 7 to turn on; the granular raw material is fed from the pipe inlet above the granular raw material conveying pipe 1 and falls; the first blower 4 blows and forms a transverse airflow through the first blow pipe 2, blowing the dust on the granular raw material into the dust removal pipe 3; at the same time, the second blower 7 blows and generates an inclined airflow toward the end of the dust removal pipe 3 through the second blow pipe 6. Under the combined action of the transverse airflow and the inclined airflow, the dust is blown to the dust collector 5 at the end of the dust removal pipe 3 for recovery; and the granular raw material falls into the granular raw material collector 8 at the lower end of the granular raw material conveying pipe 1 for collection and utilization due to the specific gravity difference with the dust. When the induction switch 9 senses that there is no dust passing through the dust removal pipe 3, the induction switch 9 feeds back to the controller, and the controller controls the first blower 4 and / or the second blower 7 to turn off.

[0038] Compared with the prior art, the dust recovery and processing device for conveying particle raw materials in a pipeline of the utility model has a simple structure, can quickly remove dust on the raw material particles, prevent the dust on the raw material particles from affecting subsequent production, and improve product quality and production smoothness; at the same time, the dust is recovered by using a dust collector, which can prevent dust leakage and reduce the harm of dust to the environment and operators.

[0039] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent.
