[0030] In order to further understand the features, technical means, specific objectives and functions achieved by the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] like Figure 1 and Figure 2 As shown, this application provides:

[0032] A dust removal system for removing foreign matter and dirt inside and outside a container 5 is characterized in that it includes a dust removal box 1, a stepping conveying mechanism 2 and a dust removal mechanism 3. The dust removal box 1 has a dust cleaning chamber and a suction port 11 for maintaining the pressure of the dust cleaning chamber lower than the atmospheric pressure; the stepping conveying mechanism 2 is horizontally arranged in the dust cleaning chamber, and the two ends of the stepping conveying mechanism 2 respectively pass through the two sides of the dust removal box 1. The stepping conveying mechanism 2 has a conveying surface extending in the horizontal direction, and the conveying surface has placement grooves 21 arranged along its conveying direction. The length of the placement grooves 21 extends along the width direction of the conveying surface. The container 5 is placed in the placement grooves 21 and its container 5 mouth is exposed along its length direction; the dust removal mechanism 3 has a blowing pipe 31 that can be inserted into the container 5 through the container 5 mouth. After the blowing pipe 31 is inserted into the container 5, it can be synchronously moved with the container 5 for a set distance and then pulled out and inserted into the next container 5. High-pressure gas is passed into one end of the blowing pipe 31.

[0033] The container 5 is cylindrical, and its diameter is smaller than the groove diameter of the placement groove 21 , so that the container 5 can be stably placed in the placement groove 21 .

[0034] When in use, the container 5 is placed in the placement slot 21, and the stepping conveying mechanism 2 is started. The stepping conveying mechanism 2 can drive the container 5 to move horizontally into the dust removal box 1. When the container 5 moves into the dust removal box 1, the blowing pipe 31 in the dust removal mechanism 3 can be plugged into the container 5, and high-pressure gas is introduced into the port of the blowing pipe 31, so that the high-pressure gas can blow out the dust in the container 5, and the dust on the outer surface of the container 5 is pumped out from the dust cleaning chamber by the exhaust port, so as to clean the dust or foreign matter on the inner and outer surfaces of the container 5. After the blowing pipe 31 moves synchronously with the plugged-in container 5 for a distance, the blowing pipe 31 withdraws from the container 5, and then is reinserted into the next container 5, and high-pressure gas is introduced again to clean the container 5.

[0035] This embodiment places the container 5 in the placement groove 21 of the stepping conveying mechanism 2, so that the stepping conveying mechanism 2 can drive the container 5 to move step by step. When the container 5 moves to the dust cleaning chamber of the dust removal box 1, the blowing pipe 31 can be inserted into the container 5 and move synchronously with it, so that the blowing pipe group can blow out the dust in the container 5 and the dust on the surface of the container 5 is sucked away by the suction port 11, which solves the problem that the existing container 5 dust removal device cannot clean the dust on the surface and inside of the container 5 at the same time, has higher cleaning efficiency, and can effectively clean the outer surface and inner surface of the container 5.

[0036] like Figure 4 As shown, the placement groove 21 is a V-shaped groove, and the placement groove 21 has a first inclined surface 211 and a second inclined surface 212 that contact the outer circumference of the container 5. The first inclined surface 211 and the second inclined surface 212 are symmetrically arranged on the conveying surface of the stepping conveying mechanism 2 along the vertical plane therebetween.

[0037] Because the placement groove 21 is a V-shaped groove, the V-shaped groove can reduce the contact area between the outer circumference of the container 5 and it, so that after the container 5 enters the dust cleaning chamber, the dust on the surface of the container 5 can be separated from the container 5 as much as possible, so that the dust can be sucked out from the gap between the V-shaped groove and the container 5 by the suction port 11, thereby cleaning the container 5.

[0038] like Figure 2 As shown, the dust removal box 1 also has a suction chamber separated from the dust cleaning chamber, the suction port 11 connects the dust cleaning chamber and the suction chamber, and an exhaust fan 41 is provided in the suction chamber. The exhaust fan 41 has an air inlet and an air outlet. The air inlet is connected to the suction port 11, and the air outlet is connected to the suction chamber.

[0039] When the exhaust fan 41 is started, the air inlet of the exhaust fan 41 is connected to the exhaust port, so that the exhaust fan can suck the air carrying dust or foreign matter in the dust cleaning chamber into the suction chamber, thereby preventing the accumulation of dust or foreign matter in the dust cleaning chamber and affecting the cleaning effect of the container 5. Therefore, the exhaust fan 41 can effectively clean the dust on the inner and outer surfaces of the container 5.

[0040] like Figure 2 and Figure 3 As shown, the dust cleaning chamber is also provided with a suction pipe 42 extending along the conveying direction of the stepping conveyor, the suction port 11 is provided on the suction pipe 42 and extends along its length direction, both ends of the suction pipe 42 pass through the dust cleaning chamber and extend into the suction chamber, and the pipe mouth of the suction pipe 42 is connected to the air inlet of the exhaust fan 41.

[0041] By setting the suction pipe 42 in the dust cleaning chamber, when the vacuum fan is working, the air in the suction pipe 42 can be sucked into the suction chamber by the vacuum fan, and the suction pipe 42 is under negative pressure, so that the dust or foreign matter in the dust cleaning chamber can be sucked into the suction pipe 42, and then the dust or foreign matter in the dust cleaning chamber can be discharged, preventing the dust or foreign matter from secondary contamination of the container 5.

[0042] like Figure 2 and Figure 3 As shown, a filter bag 43 is provided at the air outlet of the exhaust fan 41 and is in communication with the exhaust fan 41 .

[0043] By arranging a filter bag 43 at the air outlet of the exhaust fan 41, the dust or foreign matter in the air extracted by the exhaust fan 41 can be gathered in the filter bag 43, preventing the foreign matter or dust from contaminating the suction chamber and avoiding difficulty in cleaning the suction chamber later.

[0044] like Figure 3As shown, the dust removal mechanism 3 includes a transverse mover 381, a longitudinal mover 382 and a connecting frame 383. The transverse mover 381 is movably arranged in the dust cleaning chamber of the dust removal box 1 along the width direction of the stepping conveying mechanism 2, and the transverse mover 381 has a first moving part that moves along the length direction of the stepping conveying mechanism 2; the longitudinal mover 382 is fixedly arranged in the dust cleaning chamber of the dust removal box 1, and the longitudinal mover 382 has a second moving part that moves along the width direction of the stepping conveying mechanism 2, and the second moving part is connected to the transverse mover 381; the connecting frame 383 is arranged on the first moving part, and the connecting frame 383 extends longitudinally. The connecting frame 383 has mounting holes arranged at equal intervals along the length direction of the stepping conveying mechanism 2, and the blowing pipe 31 is arranged in the mounting hole.

[0045] When the blowing pipe 31 is inserted into the container 5 and needs to move synchronously with the container 5, the transverse mover 381 is started so that the first moving part of the transverse mover 381 can drive the connecting frame 383 and the blowing pipe 31 on the connecting frame 383 to move synchronously with the container 5 along the output direction of the stepping conveying mechanism 2. When the blowing pipe 31 needs to be withdrawn from the container 5, the longitudinal mover 382 is started so that the second moving part of the longitudinal mover 382 drives the transverse mover 381, the connecting frame 383 and the blowing pipe 31 away from the container 5, so that the blowing pipe 31 can be withdrawn from the container 5, and then the blowing pipe 31 can be reinserted into the next container 5 and blown.

[0046] The lateral mover 381 and the longitudinal mover 382 are respectively one of a ball screw slide or a synchronous belt slide, and the ball screw slide or the synchronous belt slide are both existing technologies and will not be described in detail here.

[0047] like Figure 5 and Figure 6 As shown, the blowing pipe 31 has a fixed section fixedly connected to the connecting frame 383, and a rotating section coaxially connected to the fixed section. The rotating section has a connecting section connected to the fixed section, and an extension section that can be inserted into the container 5. The connecting section is provided with an arc-shaped guide plate 332 coaxial with the connecting section, and the circumferential surface of the extension section is provided with a slender groove 341 extending along its length direction.

[0048] When high-pressure gas is injected into the fixed section of the blowing pipe 31, the high-pressure gas acts on the surface of the arc-shaped flow guide 332 of the connecting section in the axial direction. When the surface of the arc-shaped flow guide 332 is subjected to force, the arc-shaped flow guide 332 drives the connecting section to rotate coaxially in the fixed section, thereby synchronously rotating the connecting section inserted into the container 5. The circumferential surface of the extension section is provided with an elongated slot 341, so that the high-pressure gas passing through the elongated slot 341 impacts the inner wall of the container 5, and the extension section rotates, so that the gas sprayed from the elongated slot 341 forms a gas brush and continuously scrapes the adhered foreign matter or dust on the inner surface of the container 5, thereby effectively improving the cleaning efficiency of the container 5.

[0049] As shown in Figure 9 and Figure 10 , the elongated slot 341 is arranged in an arc shape on the extension section.

[0050] Because the elongated slot 341 is arranged in an arc shape on the extension section, the sprayed gas brush also brushes the inner surface of the container 5 in an arc shape, and the arc-shaped gas brush can accelerate the discharge of foreign matter and dust in the container 5, thereby improving the cleaning efficiency.

[0051] As shown in Figure 7 , the blowing pipe 31 includes a fixed pipe 32, a rotating pipe 33, an insertion pipe, and a tightening head 35. The fixed pipe 32 is arranged on the connecting frame 383, one end of the fixed pipe 32 is connected to high-pressure gas, and the other end of the fixed pipe 32 has a mounting hole. The rotating pipe 33 is coaxially arranged in the mounting hole, and the outer end of the rotating pipe 33 is provided with a slot 331 distributed along the circumference thereof. The insertion pipe is coaxially inserted into the outer port of the rotating pipe 33, and the elongated slot 341 is distributed along the circumference of the circumferential surface of the insertion pipe. The tightening head 35 is coaxially arranged at the outer end of the rotating pipe 33, and the tightening head 35 is threadedly connected with the rotating pipe 33. The inner end of the tightening head 35 has an annular tapered surface which can abut against the outer port of the rotating pipe 33.

[0052] By arranging the fixed pipe 32 on the connecting frame 383, and arranging the rotating pipe 33 in the mounting hole of the fixed pipe 32 through a bearing, and inserting the insertion pipe into the outer port of the rotating pipe 33, and tightening the tightening head 35 to the rotating pipe 33, the annular tapered surface of the tightening head 35 abuts against the outer port of the rotating pipe 33. Because the outer port of the rotating pipe 33 is provided with the slot 331, the outer port of the rotating pipe 33 is gathered to tightly hold the insertion pipe, thereby stably connecting the rotating pipe 33 and the insertion pipe. The arc-shaped flow guide 332 is arranged in a fan blade shape along the circumference in the rotating pipe 33. When the rotating pipe 33 has airflow passing therethrough, the arc-shaped flow guide blade is subjected to force to drive the rotating pipe 33 to rotate.

[0053] As shown in Figure 6 , Figure 7 and Figure 8As shown, the insertion pipe comprises a first pipe 342 connected with the fixed pipe 32, and a second pipe 343 slidingly arranged in the first pipe 342, and a round head 3432 is arranged at the outer end of the second pipe 343, the inner end of the insertion pipe and the rotating pipe 33 is provided with an abutting ring 36, a spring 37 is further arranged between the inner end of the second pipe 343 and the abutting ring 36, the outer end of the inner end of the second pipe 343 is provided with a protrusion 3431, the inner circumferential surface of the first pipe 342 is provided with an elongated groove 341 and a guide groove 3421 coaxial and of the same arc, the protrusion 3431 extends into the guide groove 3421, and the first pipe 342 and the second pipe 343 are both provided with the elongated groove 341.

[0054] In order to completely clean the container 5 of different heights, the first pipe 342 and the second pipe 343 are slidingly connected to form the insertion pipe, the spring 37 is further arranged between the inner end of the second pipe 343 and the abutting ring 36, so that the second pipe 343 can elastically abut against the inner end surface of the container 5, the guide groove 3421 is coaxial and of the same arc with the elongated groove 341, so that the second pipe 343 can rotate out of the first pipe 342, the elongated grooves 341 on the first pipe 342 and the second pipe 343 are smoothly connected, the overall air brush is stable, and the protrusion 3431 ensures that the second pipe 343 can stably slide out of the first pipe 342.

[0055] The above embodiments only express one or several embodiments of the present application, and the description is more specific and detailed, but it cannot be understood as a limitation on the scope of the present application. It should be noted that for ordinary skilled in the art, without departing from the concept of the present application, several modifications and improvements can be made, which are within the scope of the present application. Therefore, the scope of protection of the present application should be subject to the appended claims.
