Description

Technical Field

[0001] This utility model relates to the field of dust removal equipment technology, and more specifically, it relates to a dust removal device for polishing round steel nails. Background Technology

[0002] The polishing of round steel nails is significant beyond simply improving their appearance. This process effectively reduces the surface roughness and removes burrs through mechanical means, achieving multiple benefits at once: reducing resistance during construction, enhancing coating adhesion, extending the fatigue life of the nails, and ensuring their appearance meets relevant standards. Nails treated in this way can be upgraded into high-value-added, exportable products. Furthermore, polishing significantly reduces scrap rates in subsequent production and losses during packaging. Typically, polishing round steel nails involves placing multiple nails in a cylindrical polishing device. However, because these devices are usually designed with an upward-opening design for easy observation of the polishing progress, this design also generates dust during the polishing process, necessitating the use of dust removal equipment.

[0003] Existing dust removal devices generally use negative pressure ventilation, with the exhaust port located directly above the cylindrical polishing machine. This draws in the dust-laden gas, filters it, and then discharges clean air. However, after running continuously for a period of time, dust accumulates on the filter screen, increasing resistance. The machine must be stopped for cleaning or filter replacement, which prevents it from working continuously. Utility Model Content

[0004] This invention provides a dust removal device for polishing round steel nails, solving the technical problem of frequent shutdowns that prevent continuous operation in related technologies.

[0005] This utility model provides a dust removal device for polishing round steel nails, including a dust collection hood and a centrifugal fan. The centrifugal fan is connected to the dust collection hood through an exhaust pipe, and a filter screen is installed inside the exhaust pipe.

[0006] The bottom of the exhaust pipe is connected to a collection mechanism for collecting waste debris, which is located on the windward side of the filter screen.

[0007] The exhaust duct is equipped with a cleaning mechanism that moves vertically and is adapted to the collection mechanism to clean the windward side of the filter screen. After cleaning the filter screen, the cleaning mechanism seals the inlet of the collection mechanism.

[0008] As a further optimization of this utility model, the collection mechanism includes a collection hopper, a cover plate and a magnetic sheet. The collection hopper is connected to the bottom of the dust hood. One side of the cover plate is rotatably connected to the outlet of the collection hopper via a hinge, and the cover plate is fastened to the collection hopper by a snap lock.

[0009] As a further optimization of this utility model, the cleaning mechanism includes a pull rod, a sealing plate, and brush bristles. One end of the pull rod slides into the interior of the exhaust pipe and is fixedly connected to the sealing plate. The brush bristles are installed on the side of the sealing plate facing the filter screen. The sealing plate is adapted to the inlet of the collection hopper.

[0010] As a further optimization of this utility model, the top end of the pull rod forms a lifting part.

[0011] As a further optimization of this utility model, the top of the exhaust pipe is rotatably connected to a support rod via a pivot, and the support rod supports the lifting part.

[0012] As a further optimization of this utility model, a magnetic plate is embedded in the bottom of the sealing plate.

[0013] As a further optimization of this utility model, a ramp is provided between the inlet of the collection hopper and the filter screen.

[0014] As a further optimization of this utility model, the collection hopper is a transparent collection hopper.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. The dust removal equipment for polishing round steel nails described in this utility model, through a cleaning mechanism that can move in the vertical direction, can clean the waste on the windward side of the filter screen without stopping the equipment, which solves the production interruption problem caused by the need to stop the machine to clean the filter screen in the prior art, ensures the continuous and stable operation of the equipment, and greatly improves production efficiency.

[0017] 2. The dust removal equipment for polishing round steel nails described in this utility model has a filter screen that effectively filters waste debris to protect the centrifugal fan. The collection hopper in the collection mechanism enables centralized collection of waste debris. The magnetic sheet can adsorb iron-containing waste debris to enhance the collection effect. After cleaning, the sealing plate seals the inlet of the collection mechanism in conjunction with the sealing structure of the cover plate, which can significantly reduce waste debris leakage and ensure a clean working environment.

[0028] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed only to enable those skilled in the art to better understand and implement the subject matter described herein, and changes may be made to the function and arrangement of the elements discussed without departing from the scope of this specification. Various processes or components may be omitted, substituted, or added as needed in the examples. Furthermore, features described in some examples may be combined in other examples.

[0029] like Figures 1 to 2 As shown in the embodiment of this utility model, a dust removal device for polishing round steel nails includes a dust collection hood 1 and a centrifugal fan 2. The centrifugal fan 2 is connected to the dust collection hood 1 through an exhaust pipe 3, and a filter screen 4 is installed inside the exhaust pipe 3.

[0030] The bottom of the exhaust pipe 3 is connected to a collection mechanism 5 for collecting waste debris, which is located on the windward side of the filter screen 4;

[0031] The exhaust pipe 3 is equipped with a cleaning mechanism 6 that moves vertically and is adapted to the collection mechanism 5 to clean the windward side of the filter screen 4. After cleaning the filter screen 4, the cleaning mechanism 6 seals the inlet of the collection mechanism 5.

[0032] When the centrifugal fan 2 is running, it generates negative pressure, which allows the dust hood 1 to suck up the waste dust generated during the polishing of round steel nails through the exhaust pipe 3. After the airflow carries the waste dust into the exhaust pipe 3, the filter screen 4 filters the waste dust. Since the collection mechanism 5 is located at the bottom of the exhaust pipe 3 on the windward side of the filter screen 4, some waste dust will fall into the collection mechanism 5 naturally due to gravity. When the waste dust accumulates on the windward side of the filter screen 4 and affects the filtration effect, the cleaning mechanism 6 moves vertically to clean the waste dust on the windward side of the filter screen 4. The cleaned waste dust falls into the collection mechanism 5. Then, the cleaning mechanism 6 is adapted to the collection mechanism 5 to seal the inlet of the collection mechanism 5 to perform the cleaning operation. Thus, the waste dust is effectively filtered through the filter screen 4, protecting the centrifugal fan 2, and the waste dust is collected centrally through the collection mechanism 5. At the same time, the cleaning mechanism 6 can clean the filter screen 4 without stopping the machine, reducing the number of equipment downtimes and ensuring continuous and stable operation of the equipment.

[0033] like Figure 3 As shown, the collection mechanism 5 includes a collection hopper 51, a cover plate 52, and a magnetic sheet 53. The collection hopper 51 is connected to the bottom of the dust hood 1. One side of the cover plate 52 is rotatably connected to the outlet of the collection hopper 51 via a hinge 54, and the cover plate 52 is fastened to the collection hopper 51 via a snap lock 55.

[0034] The collection hopper 51 in the collection mechanism 5 is connected to the bottom of the exhaust pipe 3. Waste debris falling from the windward side of the filter screen 4 will enter the collection hopper 51. The magnetic sheet 53 can adsorb the iron-containing waste debris generated by polishing the round steel nails, preventing the waste debris from drifting randomly in the collection hopper 51. When it is necessary to clean the waste debris in the collection hopper 51, the cleaning mechanism 6 seals the inlet of the collection hopper 51, opens the latch lock 55, and the cover plate 52 will rotate around the hinge 54, thereby opening the outlet of the collection hopper 51 to facilitate the pouring out of waste debris. After cleaning, rotate the cover plate 52 to close the outlet, and then fasten the cover plate 52 to the collection hopper 51 through the latch lock 55 to ensure the sealing of the collection hopper 51. The collection hopper 51 realizes the centralized collection of waste debris. The magnetic sheet 53 enhances the collection effect of iron-containing waste debris. The opening and closing structure of the cover plate 52 makes the waste debris cleaning operation more convenient, and the fastening can effectively prevent the waste debris from leaking during the collection process.

[0035] like Figure 2 and Figure 3 As shown, the cleaning mechanism 6 includes a pull rod 61, a sealing plate 62, and bristles 63. One end of the pull rod 61 slides into the interior of the exhaust pipe 3 and is fixedly connected to the sealing plate 62. The bristles 63 are installed on the side of the sealing plate 62 facing the filter screen 4. The sealing plate 62 is adapted to the inlet of the collection hopper 51.

[0036] When debris accumulates on the windward side of the filter screen 4, the pull rod 61 drives the sealing plate 62 to move vertically within the exhaust pipe 3. The bristles 63 of the sealing plate 62 facing the filter screen 4 will contact the windward side of the filter screen 4, brushing off the attached debris. The brushed debris falls into the collection hopper 51. After cleaning, the pull rod 61 is moved further to make the sealing plate 62 fit with the inlet of the collection hopper 51, thus sealing the inlet of the collection hopper 51. After cleaning, the sealing plate 62 seals the inlet of the collection hopper 51, preventing debris in the airflow from leaking directly from the collection hopper 51 without filtration.

[0037] The collection hopper 51 is a transparent collection hopper. The collection hopper 51 is made of transparent material, which allows operators to directly observe the amount of waste accumulated inside the collection hopper 51. Without opening the equipment, operators can determine whether the waste inside the collection hopper 51 needs to be cleaned. This allows operators to monitor the waste collection situation in real time, clean the collection hopper 51 in a timely manner, and avoid excessive waste accumulation and overflow, thus improving the timeliness and convenience of equipment maintenance.

[0038] Furthermore, a lifting part 611 is formed at the top of the pull rod 61.

[0039] The lifting part 611 at the top of the pull rod 61 provides an easy grip for the operator. By pulling or pressing the lifting part 611, the operator can easily move the pull rod 61 and the connected sealing plate 62 and brush bristles 63 in the vertical direction to clean the filter screen 4 and seal the inlet of the collection hopper 51. The lifting part 611 makes the operation of the pull rod 61 more convenient and labor-saving.

[0040] Furthermore, the top of the exhaust pipe 3 is rotatably connected to a support rod 64 via a pivot, and the support rod 64 supports the lifting part 611.

[0041] When it is necessary to lift the cleaning mechanism 6, pull the pull rod 61 to make the sealing plate 62 leave the inlet of the collection hopper 51, rotate the support rod 64 so that it is located below the lifting part 611, and support the lifting part 611, thereby limiting the position of the pull rod 61 and the sealing plate 62.

[0042] A magnetic plate 65 is embedded in the bottom of the sealing plate 62.

[0043] When the sealing plate 62 moves the brush bristles 63, the magnetic plate 65 at the bottom of the sealing plate 62 can pick up metal shavings to increase the cleaning effect.

[0044] A ramp is provided between the inlet of the collection bucket 51 and the filter screen 4.

[0045] The presence of a ramp facilitates the flow of waste debris into the collection hopper 51.

[0046] The embodiments of this utility model have been described above, but these embodiments are not limited to the specific implementation methods described above. The specific implementation methods described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms based on the guidance of these embodiments, all of which are within the protection scope of these embodiments.
