[0029] The following will be combined with the accompanying drawings to clarify the technical solutions in the embodiments of the present invention; although it is clear that the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] Example 1:

[0031] The present invention solves the problem in the prior art that in the process of kinetic energy carrying materials into the equipment, due to the different sizes and masses of the materials, the fine particles in the materials will fly around in the process of kinetic energy being converted into potential energy, causing serious dust. The following technical solutions are provided. Please refer to Figure 1-5 ;

[0032] A non-powered teardrop-shaped damping and settling device for treating dust generated by falling materials comprises a damping box 1, wherein an inlet 11 and an outlet are respectively provided on two symmetrical sides of the damping box 1, an assembly component 2 is provided on the top wall of the damping box 1, and a top plate component 3 is connected to the assembly component 2 through the inlet 11;

[0033] Several lifting assemblies 4 are evenly spaced and distributed in a stepped manner on the top plate assembly 3. The bottoms of the lifting assemblies 4 are connected to the damping and sinking assemblies 5. One end of the regulating assembly 6 is located outside the damping box 1 and the other end is connected to the lifting assembly 4.

[0034] The assembly component 2 includes a left side plate 21, a right side plate 22, a reinforcing rib 23 and a limit plate 24. The left side plate 21 and the right side plate 22 are symmetrically arranged on the two inner walls of the top of the damping box 1. The bottoms of the left side plate 21 and the right side plate 22 are welded to the damping box 1 through the reinforcing rib 23, and both ends of the left side plate 21 and the right side plate 22 extend to the inlet 11 and the outlet;

[0035] Specifically, the reinforcing ribs 23 provide support for the left side panel 21 and the right side panel 22. The protruding length of the left side panel 21 and the right side panel 22 does not exceed 4 cm, and the lifting component 4 can drive the damping and sinking component 5 to adjust the height through the left side panel 21 and the right side panel 22, thereby achieving adaptive adjustment for areas where dust particles float to different degrees.

[0036] The limiting plates 24 are fixed to the ports of the left plate 21 and the right plate 22 at the outlet position, and are used to limit the movement of the top plate assembly 3 .

[0037] The top plate assembly 3 includes a frame 31, a rotating shaft 32, a roller 33 and a cover plate 34. The rotating shaft 32 is provided at the two symmetrical end corners of the frame 31. The bearing of the roller 33 is penetrated by the rotating shaft 32. The cover plate 34 is fixed in the frame 31.

[0038] The frame 31 is inserted into the damper box 1 through the inlet 11 , and the two rotating shafts 32 are in contact with the top surfaces of the left plate 21 and the right plate 22 .

[0039] Specifically, during assembly, the frame 31 is inserted into the damping box 1 from the inlet 11, and the roller 33 of the rotating shaft 32 is used to contact the left plate 21 and the right plate 22 to reduce friction during sliding. After the frame 31 is inserted, the movement distance of the frame 31 is limited by the set limit plate 24 to prevent the frame 31 from sliding out of the damping box 1.

[0040] The lifting assembly 4 includes a suspension plate 41, a suspension 42 and a jacket 43. The suspension 42 is provided with multiple equally spaced sections fixed on the bottom surface of the cover plate 34. The suspension plates 41 are connected to the suspensions 42 correspondingly, and a jacket 43 is provided at the bottom of each suspension plate 41. The heights of the jackets 43 are increased sequentially, among which the jacket 43 near the inlet 11 is the shortest and the jacket 43 near the outlet is the longest.

[0041] The damping and settling assembly 5 includes a damping plate 51 and a wear-resistant rubber strip 52. The damping plate 51 includes a damping front plate 511 and a damping rear plate 512. The damping front plate 511 and the damping rear plate 512 are spliced ​​together by bolts. The bottoms of the damping front plate 511 and the damping rear plate 512 are spliced ​​with slots at equal intervals, and the tops are spliced ​​with screw holes.

[0042] The wear-resistant rubber strip 52 is inserted into the slot, and a channel is left between the two cylinders of the wear-resistant rubber strip 52 to facilitate dust reduction.

[0043] The regulating assembly 6 includes a control shaft 61, a transmission shaft 62, a first bevel gear set 63, a second bevel gear set 64 and a transmission screw 65. The control shaft 61 passes through the side wall of the damping box 1. The damping box 1 inside the control shaft 61 is engaged with one end of the transmission shaft 62 through the first bevel gear set 63. The other end of the transmission shaft 62 passes through several outer sleeves 43 in sequence. The transmission shaft 62 is located inside the outer sleeve 43 and is provided with a second bevel gear set 64. Each second bevel gear set 64 is engaged with a screw hole through a transmission screw 65.

[0044] Specifically, the H-shaped suspension plate 41 and the suspension 42 are provided to improve the support strength of the outer sleeve 43, and the outer sleeve 43 is penetrated by the transmission shaft 62, providing support for the rotation of the transmission shaft 62;

[0045] The damping plate 51 adopts an assembled structure of a damping front plate 511 and a damping rear plate 512, which makes it convenient to open or lock the damping front plate 511 and the damping rear plate 512. When the damping front plate 511 and the damping rear plate 512 are opened, the wear-resistant rubber strip 52 is inserted into the slot in turn, and the bolt is clamped in the screw hole of the damping plate 51.

[0046] When the height of the damping and sinking assembly 5 needs to be adjusted, the control shaft 61 is rotated to drive the transmission shaft 62 to rotate through the first bevel gear set 63. The rotation of the transmission shaft 62 in turn drives the transmission screw 65 to rotate through the second bevel gear set 64, thereby driving the damping and sinking assemblies 5 to rise or fall synchronously. Since there are multiple groups of damping and sinking assemblies 5, and their lengths are distributed in a stepped manner;

[0047] The main material of the wear-resistant rubber strip 52 is wear-resistant rubber, which is not only wear-resistant, but also if the airflow is large, the rubber can swing slightly to slow down the airflow speed and reduce the airflow pressure. The airflow enters the damping box 1, and the dust particles first contact the damping and settling components 5 with a lower height in the damping box 1. The airflow is partially blocked, and some dust particles in the airflow are decelerated and collide, combine, and settle in the damping box 1. Through the stepped setting, the airflow speed is continuously reduced, which is conducive to the collision, combination, and settlement of dust particles, thereby achieving the purpose of settlement in an unpowered state.

[0048] Example 2:

[0049] See also Figure 6-7 The damping plates 51 of the damping and settling assembly 5 described in this embodiment adopt a gradually contracting structure. There are two groups of damping plates 51, and the two groups of damping plates 51 are symmetrically arranged on the two side walls of the damping box 1. Among them, the width of the damping plate 51 at the middle position of each group of damping plates 51 is 4a, and the width of the outermost damping plate 51 is a. The width of the damping plate 51 from the outermost damping plate 51 to the middle position increases by the length a in sequence. When the airflow containing dust enters, since the length of the damping plates on both sides increases from a to 4a, the spacing between the damping plates on both sides becomes smaller and smaller, the entry space of the dust-containing airflow is gradually tightened, the kinetic energy of the dust is weakened, and the purpose of rapid sedimentation is achieved.

[0050] Example 3:

[0051] See also Figure 8 The damping plates 51 of the damping and settling component 5 adopt a turbulent structure. There are two groups of damping plates 51. The two groups of damping plates 51 are symmetrically arranged on the two side walls of the damping box 1. The width of the damping plates 51 is a. The damping plates 51 are clamped on the damping box 1. The damping plates 51 on the side walls of one of the damping boxes 1 are staggered at intervals. The staggered distance increases from a to 3a. When the airflow containing dust enters, it enters from the staggered intervals, changing the dust's travel path so that it is no longer a linear motion, gradually slowing down the kinetic energy of the dust, and achieving the purpose of rapid sedimentation.
