[0034] Combine the following Figures 1 to 3 The utility model describes a pulse dust removal device for tobacco production.

[0035] like Figures 1 to 3As shown, the utility model provides a pulse dust removal device for tobacco production, comprising: a box body 1, a mounting frame 2, a partition plate 3, a baffle 4, a plurality of air inlet pipes 5 and a plurality of blowing pipes 6; the partition plate 3 is arranged in the box body 1 and divides the box body 1 into a first cavity 11 and a second cavity 12, the plurality of blowing pipes 6 are all arranged in the first cavity 11, the first ends of the plurality of blowing pipes 6 are all connected to the plurality of air inlet pipes 5 penetrating into the first cavity 11 in a one-to-one correspondence, and the air inlet pipes 5 are used to introduce pulse airflow into the blowing pipes 6 The second ends of the multiple blowing tubes 6 are connected to the mounting frame 2 arranged in the first cavity 11, the baffle 4 is arranged on the side of the multiple blowing tubes 6 away from the mounting frame 2, the baffle 4 is connected to the mounting frame 2, and any blowing tube 6 is in contact with the baffle 4; the blowing tube 6 is provided with a blowing hole on the side facing the partition plate 3, and for any blowing hole, there is a jet port corresponding to it on the partition plate 3, one side of the jet port is connected to the corresponding blowing hole, and the other side of the jet port is used to connect with the filter bag 200 arranged in the second cavity 12.

[0036] Specifically, a pulse valve is provided on the air inlet pipe 5, and the air inlet pipe 5 is connected to an air source. The air source is combined with the pulse valve to introduce a pulse airflow into the blowing pipe 6. The blowing pipe 6 is provided with a plurality of blowing holes at intervals along its axial direction. The blowing holes blow out a pulse airflow through the air jet and enters the second cavity 12. A plurality of filter bags 200 are provided in the second cavity 12. The filter bags 200 are fixed on the partition plate 3, and the filter bags 200 are covered on the air jet. The pulse airflow can make the filter bags 200 expand and shake rapidly, thereby causing dust to fall off. A funnel-shaped dust removal port is provided at the bottom of the second cavity 12, and the bottom of the dust removal port is connected to a dust storage bin to collect dust.

[0037] The second end of the blow pipe 6 is connected to the mounting frame 2, and the mounting frame 2 is connected to the partition plate 3 or the box body 1. The baffle 4 is arranged on the side of the multiple blow pipes 6 away from the mounting frame 2. The blow pipes 6 are all in contact with the baffle 4, so the baffle 4 can press the second ends of the multiple blow pipes 6 onto the mounting frame 2. Even if the blow pipe 6 becomes loose, the baffle 4 can still limit the blow pipe 6 to prevent the position of the blow pipe 6 from shifting.

[0038] The pulse dust removal device for tobacco production of the utility model blows out a pulse airflow through the blow pipe 6, thereby causing dust on the filter bag 200 to fall off, and the filter bag 200 is separately arranged in the second cavity 12 to prevent dust from contaminating other components in the first cavity 11; the baffle 4 can firmly press the second ends of all the blow pipes 6 onto the mounting frame 2, thereby limiting the position of each blow pipe 6, so that even if the connection between the blow pipe 6 and the mounting frame 2 becomes loose, the baffle 4 can still prevent the water spray pipe from moving, thereby solving the problem that the position of the blow pipe 6 is easily offset in the prior art.

[0039] like Figure 2As shown, in some embodiments, multiple blowing pipes 6 are arranged at intervals along the first direction, and multiple blowing pipes 6 are arranged along the second direction, the first direction and the second direction are perpendicular to each other, and the first direction and the second direction are parallel to the partition plate 3.

[0040] like Figures 2 to 3 As shown, in some embodiments, the baffle 4 includes a plurality of fitting portions 41 and a plurality of raised portions 42, the plurality of fitting portions 41 are arranged at intervals, any two adjacent fitting portions 41 are connected by a raised portion 42, the fitting portions 41 are fitted with the mounting frame 2, there are gaps between the raised portions 42 and the mounting frame 2, and the second ends of the plurality of blowing tubes 6 are arranged in the plurality of gaps one by one.

[0041] Specifically, by providing the protrusion 42, the blowing tube 6 can be restricted between the protrusion 42 and the mounting frame 2, and the protrusion 42 can prevent the blowing tube 6 from moving in a direction perpendicular to the partition plate 3. The fitting portion 41 fits with the mounting frame 2, so that the blowing tube 6 cannot move between the fitting portion 41 and the mounting frame 2, thereby preventing the blowing tube 6 from moving in the first direction.

[0042] like Figure 1 and Figure 3 As shown, in some embodiments, the mounting frame 2 is provided with grooves 21 , the number of the grooves 21 is equal to and corresponds to the blowing tubes 6 , and the second ends of the blowing tubes 6 are all disposed in the corresponding grooves 21 .

[0043] Specifically, the position of the groove 21 and the protrusion 42 are respectively located on the opposite sides of the corresponding blow pipe 6. By setting the second end of the blow pipe 6 in the groove 21, the second end of the blow pipe 6 is further limited. In combination with the protrusion 42 and the fitting portion 41, the blow pipe 6 can be more effectively prevented from moving along the first direction.

[0044] like Figure 1 to Figure 2 As shown, in some embodiments, the pulse dust removal device for tobacco production also includes a first connecting component, the number of the first connecting components is equal to and corresponds one to one with the protrusions 42, and the first connecting component includes two first bolts 7. The two first bolts 7 of any first connecting component are respectively arranged on the fitting portions 41 on the opposite sides of the corresponding protrusion 42, and the two first bolts 7 are both adjacent to the corresponding protrusion 42.

[0045] Specifically, the two first bolts 7 of the first connecting assembly are spaced apart along the first direction, and the area of ​​the fitting portion 41 adjacent to the protruding portion 42 is connected to the mounting frame 2 by the first bolts 7, thereby preventing the protruding portion 42 and the fitting portion 41 from moving in a direction away from the mounting frame 2, causing the protruding portion 42 and the fitting portion 41 to lose their limiting effect on the blow pipe 6, thereby preventing the blow pipe 6 from moving.

[0046] like Figures 1 to 3As shown, in some embodiments, the pulse dust removal device for tobacco production also includes a second connecting assembly, the second connecting assembly includes a plurality of second bolts 8, the number of the second bolts 8 is equal to and corresponds one to one with the blow pipes 6, the second bolts 8 penetrate the baffle 4 and the corresponding blow pipe 6 and are threadedly connected to the mounting frame 2.

[0047] Specifically, the baffle 4, the blow pipe 6 and the mounting frame 2 are directly connected by the second bolt 8, thereby ensuring that the blow pipe 6 can always fit tightly with the baffle 4 and the mounting frame 2, avoiding the vibration of the blow pipe 6 causing the blow pipe 6 to hit the baffle 4 and the mounting frame 2 and generate loud noise, and also preventing the baffle 4 or the blow pipe 6 from being deformed due to prolonged knocking, resulting in a reduction in the limiting effect of the baffle 4 on the blow pipe 6.

[0048] like Figures 1 to 3 As shown, in some embodiments, the second end of the blowing tube 6 is flat.

[0049] Specifically, by setting the second end of the blowing pipe 6 to be flat, the contact area between the second end of the blowing pipe 6 and the baffle 4 and the mounting frame 2 is increased, the friction force is increased, and compared with the conventional circular structure, the flat structure is not easy to slide, and it is also easier to drill holes for the second bolt 8 to pass through. Specifically, before the blowing pipe 6 is installed, the second end of the blowing pipe 6 can be pressed from a circular structure to a flat structure, so that the second end of the blowing pipe 6 does not have space for deformation again, and the second end of the blowing pipe 6 will not be deformed again due to the pressure of the baffle 4 and the mounting frame 2, ensuring that the second end of the blowing pipe 6 will not be out of contact with the baffle 4 and the mounting frame 2.

[0050] like Figure 1 to Figure 2 As shown, in some embodiments, the baffle 4 is in the shape of a rectangular strip, and the long side direction of the baffle 4 is arranged along the first direction; the pulse dust removal device for tobacco production also includes two third connecting components, and the opposite ends of the baffle 4 along the first direction are connected to the mounting frame 2 one by one through the two third connecting components.

[0051] Specifically, the long side direction of the baffle 4 is arranged along the direction of the spacing between the plurality of blowing tubes 6, so that all the blowing tubes 6 can be limited. The baffle 4 can be made of high-strength materials such as stainless steel.

[0052] like Figure 1 to Figure 2 As shown, the third connecting assembly includes two third bolts 9 spaced apart along the second direction. Compared with the plurality of first bolts 7 and the plurality of second bolts 8 spaced apart along the first direction, the two third bolts 9 can fix the baffle 4 in other directions to ensure that the end of the baffle 4 will not be separated from the mounting frame 2. Moreover, the third connecting assembly includes two third bolts 9. Even if one of the third bolts 9 is loosened, the end of the baffle 4 will not be loosened.

[0053] In some embodiments, shock-absorbing pads (not shown) are provided on the side of the baffle 4 facing the mounting frame 2 and on the side of the mounting frame 2 facing the blow pipe 6. By providing the shock-absorbing pads, the impact of the vibration of the blow pipe 6 is reduced, the possibility of loosening of the first bolt 7, the second bolt 8 and the third bolt 9 is reduced, and the noise generated by the vibration is also reduced.

[0054] In some embodiments, the shock-absorbing pad is a rough rubber pad. The use of a rough rubber pad helps to increase friction and prevent the blow pipe 6 from moving. The rubber pad has a certain degree of deformability and can effectively fill the gap between the baffle 4, the blow pipe 6 and the mounting frame 2 to avoid the baffle 4, the blow pipe 6 and the mounting frame 2 from being unable to fit tightly together due to preparation errors and other reasons, resulting in collisions with each other during vibration.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
