For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0031] Please refer to Figures 1 to 4 , and now the on-line dust removal device provided by the present invention will be described. The on-line dust removal device includes a protective cover 1 that can cover the outside of the product and a driving mechanism 2 for driving the lifting of the protective cover 1. The protective cover 1 is an open cavity body 12 with an opening 11 at one end. An air inlet pipe 13 and an air outlet pipe 14 are opened at the bottom of the open cavity body 12, and the product can be located inside the open cavity body 12. The air inlet pipe 13 and the air outlet pipe 14 are connected and communicated through the open cavity body 12.

[0032] Compared with the prior art, for the on-line dust removal device provided by the present invention, the protective cover 1 can directly cover the outside of the product, and the air inlet pipe 13 can blow air into the inside of the open cavity body 12, so as to blow up the particulate impurities carried by the product to a high pressure inside the open cavity body 12. The air outlet pipe 14 can perform an air extraction operation, so as to suck up the particulate impurities flying inside the open cavity body 12 and the particulate impurities still remaining on the product, form a reflux inside the open cavity body 12, and blow the particulate impurities away from the product, which can achieve a good dust removal effect. And the whole on-line dust removal device can be integrated with the production line. Only by driving the protective cover 1 to move up and down by the driving mechanism 2 can on-line dust removal be realized. It not only has a simple structure, low production cost, but also does not reduce the processing efficiency of the whole production line.

[0033] Specifically, the protective cover 1 is an open cavity body 12 with an opening 11 at one end, and the shape of the open cavity body 12 can be cylindrical or prismatic, which is not uniquely limited here. The bottom of the open cavity body 12 is relatively thick, and both the air inlet pipe 13 and the air outlet pipe 14 are directly opened at the bottom of the open cavity body 12, that is, on the end face of the protective cover 1 far away from the opening 11.

[0034] Further, please refer to Figures 3 to 4, as a specific implementation of the on-line dust removal device provided by the present invention, the air outlet pipe 14 is located at the center of the bottom of the open cavity 12, and the air inlet pipe 13 is arranged around the air outlet pipe 14. Specifically, the air outlet pipe 14 is located at the central position, and the air inlet pipe 13 is arranged outside the air outlet pipe 14 in a ring shape, and the diameter of the air outlet pipe 14 is larger than that of the air inlet pipe 13, so as to ensure that the high-pressure gas enters the inside of the open cavity 12 through the air inlet pipe 13, and the high-pressure gas is evenly sprayed on the outer surface of the product. And due to the collision between the air flows, more air flows stagnate in the central area and are then discharged through the air outlet pipe 14. At this time, the dust removal effect of the whole device can be better ensured. Of course, according to the actual situation and specific requirements, in other embodiments of the present invention, the air inlet pipe 13 can also be arranged at the center of the bottom of the open cavity 12, and the air outlet pipe 14 is arranged outside the air inlet pipe 13 in a ring shape, which is not limited uniquely here.

[0035] Further, as a specific implementation of the on-line dust removal device provided by the present invention, the air outlet pipe 14 is connected to a suction device (not shown in the figure), and the air inlet pipe 13 is communicated with a high-pressure blowing device (not shown in the figure). Specifically, an air outlet pipe joint is provided at one end of the air outlet pipe 14 away from the protective cover 1, and this air outlet pipe joint can be directly connected to the suction device, so as to directly extract the gas inside the open cavity 12, and this suction device can be connected to a vacuum filter (not shown in the figure). The dust and impurities in the extracted gas can be directly filtered through the vacuum filter, so as to play a role in purifying the air. An air inlet pipe joint is also provided on one side of the air inlet pipe 13 away from the open cavity 12. The air inlet pipe joint can be such that each air inlet pipe 13 has an air inlet pipe joint, or all the air inlet pipes 13 are communicated through an air inlet channel, and the air inlet pipe joint is communicated with this air inlet channel, and then this air inlet pipe joint can be respectively connected to a high-pressure blowing device, or can be simultaneously connected to a high-pressure blowing device, which is not limited uniquely here.

[0036] Further, refer to Figure 4 , as a specific implementation of the on-line dust removal device provided by the present invention, a guiding inclined surface 121 is provided at the bottom of the open cavity 12, and the guiding inclined surface 121 is inclined towards the air outlet pipe 14. Specifically, the guiding inclined surface 121 is located on the side of the open cavity 12 away from the opening 11, and one end of the guiding inclined surface 121 is connected to the side wall of the open cavity 12, and the other end is connected to the bottom surface of the open cavity 12, and the guiding inclined surface 121 is inclined towards the bottom surface of the open cavity 12. At this time, it can play a guiding role for the air flow, so that the gas on both sides can move towards the central air outlet pipe 14, ensuring that the gas can be accurately blown out from the air outlet pipe 14, and avoiding the gas containing impurities from staying at the corners of the open cavity 12 and reducing the dust removal effect.

[0037] Further, please refer to Figure 3 and Figure 4 , as a specific embodiment of the online dust removal device provided by the present invention, a plurality of extension pipes 15 communicating with the air inlet pipe 13 are further arranged in the open cavity 12, and the length direction of the extension pipe 15 is consistent with the height direction of the open cavity 12. Specifically, the extension pipe 15 can extend the length of the air inlet pipe 13, so that the air blown out by the air inlet pipe 13 can directly blow downward onto the surface of the product, avoiding the problem of excessive distance between the air inlet pipe 13 and the product, which may lead to a decrease in wind speed. Of course, according to the actual situation and specific requirements, in other embodiments of the present invention, the extension pipe 15 may also have a bent portion, so that the high-pressure gas can blow toward the product from the side, which is not uniquely limited here.

[0038] Further, please refer to Figure 3 and Figure 4 , as a specific embodiment of the online dust removal device provided by the present invention, the length of the extension pipe 15 is less than the height of the open cavity 12. Specifically, the side of the open cavity 12 close to the opening 11 is used to sleeved the product, and the side of the open cavity 12 close to the opening 11 can be directly attached to the support surface for supporting the product, so as to form a closed chamber by the open cavity 12 and the bottom surface. Since the product still needs to be accommodated inside the open cavity 12, the length of the extension pipe 15 should be less than the height of the open cavity 12, so as to reserve a space for accommodating the product.

[0039] Further, please refer to Figure 3 and Figure 4 , as a specific embodiment of the online dust removal device provided by the present invention, a baffle 16 for blocking the movement of the product is further arranged at one end of the extension pipe 15 away from the air inlet pipe 13, and both ends of the baffle 16 are respectively connected to any two relatively arranged extension pipes 15. Specifically, the baffle 16 is horizontally arranged inside the open cavity 12, and both ends of the baffle 16 can be directly fixed to two relatively arranged extension pipes 15. At this time, the product can be pressed by the baffle 16 to ensure that the product will not move upward due to the suction force during air extraction. Among them, the baffle 16 can also be directly fixed on the side wall of the open cavity 12, which is not uniquely limited here.

[0040] Further, please refer to Figure 1, as a specific embodiment of the online dust removal device provided by the present invention, the driving device includes a lifting cylinder 21, and the movable end of the lifting cylinder 21 is fixedly connected to the protective cover 1. Specifically, the lifting cylinder 21 is used to drive the up and down movement of the protective cover 1. When the product moves to the lower part of the protective cover 1, the protective cover 1 can move downward under the drive of the lifting cylinder 21 and cover the product in the open cavity 12. After the dust removal operation is completed, the protective cover 1 can rise upward under the drive of the lifting cylinder 21 without affecting the continuous movement of the product. The lifting cylinder 21 has a fixed end and a movable end. The movable end can be directly fixedly connected to the protective cover 1, or the fixed connection between the movable end and the protective cover 1 can be realized through a fixing plate 22, so as to control the height of the protective cover 1. Of course, according to the actual situation and specific requirements, in other embodiments of the present invention, the driving mechanism 2 can also adopt an electric push rod or other mechanisms that can realize lifting, which is not limited uniquely here.

[0041] Further, please refer to Figure 1 , as a specific embodiment of the online dust removal device provided by the present invention, it further includes a bracket group 3 for supporting the lifting cylinder 21. The bracket group 3 includes a connecting plate 31 for fixing the fixed end of the lifting cylinder 21 and columns 32 arranged on opposite sides of the connecting plate 31. Specifically, the bracket group 3 is used to support the entire lifting cylinder 21 and the protective cover 1. The columns 32 are generally directly fixed to a fixed component to support the connecting plate 31, and the lifting cylinder 21 is fixed to one side of the connecting plate 31, so as to realize the fixation and support of the entire online dust removal device.

[0042] Please refer to Figures 1 to 4 , the present invention also provides an operation method of the online dust removal device. The operation method of the online dust removal device includes the following steps:

[0043] The product moves to the lower part of the protective cover 1, and the lifting cylinder 21 drives the protective cover 1 to move downward and cover the product in the open cavity 12. The support surface for supporting the product and the open cavity 12 together form a closed space;

[0044] The air outlet pipe 14 can blow out high-pressure gas driven by a high-pressure blowing device and raise the particulate impurities carried by the product through high-pressure purging;

[0045] The air outlet pipe 14 extracts gas from the closed space driven by an air extraction device and sucks away the dust impurities adsorbed on the surface of the product and in the closed space;

[0046] After the dust removal is completed, the lifting cylinder 21 raises the protective cover 1, and the product moves out from under the protective cover 1 driven by a conveyor belt or other transmission mechanisms.

[0047] The operation method of the on-line dust removal device provided by the present invention is as follows. The protective cover 1 can be directly covered on the outside of the product. The air inlet pipe 13 can blow air towards the inside of the open cavity 12, so as to blow up the particulate impurities carried by the product to the inside of the open cavity 12 under high pressure. The air outlet pipe 14 can perform air extraction operation, so as to suck up the particulate impurities flying in the inside of the open cavity 12 and the particulate impurities still remaining on the product, form a reflux inside the open cavity 12 and blow the particulate impurities away from the product, which can achieve a good dust removal effect. And the whole on-line dust removal device can be integrated with the production line. Only by driving the protective cover 1 to move up and down by the driving mechanism 2 can on-line dust removal be realized. It not only has a simple structure and low production cost, but also does not reduce the processing efficiency of the whole production line.

[0048] Obviously, the above embodiments are only examples for clear illustration and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
