Technical Field
[0001] The utility model belongs to the technical field of dust collection, and in particular relates to a dust collecting device for a discharge pipe of a powder batching equipment. Background Art
[0002] In the dust collection system of automatic powder batching equipment, the traditional dust collection pipeline is generally directly connected to the dust collector for dust collection. In this way, a large amount of material will be sucked away during the dust collection process, causing more and more material to accumulate in the pipeline. When it accumulates to a certain extent, it will cause a burden on the pipeline and must be cleaned manually, which invisibly increases the workload.
[0003] In addition, when there are many types of materials to be batched, the materials recovered in the dust collector are mixed materials. For materials with strict formula requirements, the materials recovered by the dust collector can only be discarded, resulting in material waste. Therefore, how to reduce the loss of materials in the dust collection process and realize material recycling and reuse has become a technical problem that needs to be solved urgently. Summary of the invention
[0004] The technical problem to be solved by the utility model is to provide a dust collecting device for a discharge pipe of a powder batching equipment, which improves the recovery and reuse of materials by adding a dust collecting back-blowing structure, reduces the mixing of materials recovered in the pipeline with other types of materials, reduces the accumulation of materials in the dust collecting pipe, and thus reduces the loss of materials.
[0005] The technical solution adopted by the utility model is: a dust collecting device for a discharge pipe of a powder batching equipment is arranged at the discharge pipe of the powder batching equipment, the device comprises an inner discharge pipe connected to the discharge pipe of the powder batching equipment by means of a hose, an outer pipe sleeved on the outer side of the inner discharge pipe, a dust collecting pipe arranged on the outer side of the outer pipe, a filter element arranged in the dust collecting pipe and a back-blowing mechanism matched with the dust collecting pipe, and the free end of the dust collecting pipe is connected to a dust collector by means of a matching pipeline.
[0006] Furthermore, the angle between the dust collecting pipe and the outer pipe is between 20-30 degrees.
[0007] Furthermore, the back-blowing mechanism comprises a back-blowing pipe which is arranged on the dust collecting pipe and whose outlet cooperates with the filter element, and a back-blowing steam drum which is connected to the back-blowing pipe by means of a pulse valve.
[0008] Furthermore, the upper end surface of the outer tube and the blanking inner tube are welded to form a sealing structure.
[0009] Furthermore, the hose is made of polyethylene rainproof cloth.
[0010] The beneficial effects produced by adopting the utility model include: by adding a dust collecting back-blowing structure, improving the recycling and reuse of materials, reducing the mixing of materials recovered in the pipeline with other types of materials, reducing the accumulation of materials in the dust collecting pipe, and thus reducing the loss of materials.

[0015] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model.
[0016] See attached Figure 1-2 The dust collecting device of the discharge pipe of the powder batching equipment is arranged at the discharge pipe of the powder batching equipment. The device includes a discharge inner pipe 2 connected to the discharge pipe of the powder batching equipment by means of a hose 1, an outer pipe 3 sleeved on the outside of the discharge inner pipe 2, a dust collecting pipe 4 arranged on the outside of the outer pipe 3, a filter element 5 arranged in the dust collecting pipe 4 and a back-blowing mechanism matched with the dust collecting pipe 4. The free end of the dust collecting pipe 4 is connected to the dust collector by means of a matching pipeline. The angle between the dust collecting pipe 4 and the outer pipe 3 is between 20-30 degrees. The upper end surface of the outer pipe 3 and the discharge inner pipe 2 are welded to form a sealing structure. The material of the hose 1 is polyethylene rainproof cloth.
[0017] See attached Figure 3 The back-blowing mechanism includes a back-blowing pipe 6-1 which is arranged on the dust collecting pipe 4 and whose outlet cooperates with the filter element 5, and a back-blowing drum 6-3 which is connected to the back-blowing pipe 6-1 by means of a pulse valve 6-2.
[0018] The utility model can be installed at the discharge port of each powder silo to shorten the dust collection distance to the greatest extent, so that the recovered materials can be returned to the materials in time. During the batching process, the fan of the dust collector is started, the valve of the powder silo is opened, and the materials are dropped from the discharge port of the silo to the next station. The suspended materials in the air pass through the gap between the inner tube 2 and the outer tube 3 of the discharge material, and are filtered through the dust collecting pipe 4 and the filter element 5 with the airflow of the fan, and finally reach the dust collector; the materials attached to the outside of the filter element 5 are switched on and off by the pulse valve 6-2, and the air is supplied through the back-blowing drum 6-3, and the filter element 5 is back-blown through the back-blowing pipe 6-1, so that the materials attached to the filter element 5 fall into the discharge pipe.
[0019] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
