[0001] This utility model relates to the field of steel pipe grinding technology, specifically a dust suppression device for steel pipe grinding. Background Technology

[0002] Steel pipe grinding is a key step in metal processing, which directly affects the product's appearance, precision, and the quality of subsequent processes (such as welding and painting). A large amount of dust and debris is generated during steel pipe grinding, so dust reduction treatment is necessary.

[0003] The "dust removal device for steel pipe grinding" disclosed in publication number "CN217068172U" has a dust removal box and a water tank installed on the top surface of the workbench. The dust removal box is a rectangular shell structure with an open bottom. Several through holes are located inside the dust removal box. The outer shell is located directly below the several through holes. The outer shell is a hollow rectangular shell structure. The sweeping mechanism and the filtering mechanism are installed in the outer shell from top to bottom. The drainage mechanism is installed below the outer shell.

[0004] Traditional dust suppression devices mostly use an open structure for grinding steel pipes. However, the open structure cannot completely suppress the dust during grinding, and dust will still escape, causing pollution to the work area and harming the health of workers. At the same time, most of them rely on water mist spraying for dust suppression, which does not have the function of filtering dust, resulting in low efficiency in handling grinding dust. To address these issues, we have designed a dust suppression device for grinding steel pipes. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a dust suppression device for steel pipe grinding, which solves the problems of insufficient dust suppression during steel pipe grinding, resulting in some dust still flowing into the work area and causing pollution, and the lack of filtration and purification of the dust generated during grinding, leading to low dust suppression efficiency.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a dust suppression device for steel pipe grinding, comprising a dust prevention mechanism and a filter mechanism assembled on the front of the dust prevention mechanism;

[0007] The dustproof mechanism includes a grinding shell and a steel pipe shell. A docking cover is fixedly installed at the bottom of the grinding shell. A maintenance plate is fixedly installed on one side of the grinding shell. An opening and closing plate is movably installed at the bottom of the maintenance plate. A waste chip box is fixedly installed at the bottom of the steel pipe shell. A collection box is slidably installed inside the waste chip box.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1

[0026] Please see Figure 2-3 As shown, this embodiment proposes a dust suppression device for steel pipe grinding, including a dust prevention mechanism 1 and a filter mechanism 2 assembled on the front of the dust prevention mechanism 1. The dust prevention mechanism 1 includes a grinding housing 101 and a steel pipe housing 104. A docking cover 102 is fixedly installed at the bottom of the grinding housing 101. A maintenance plate 3 is fixedly installed on one side of the grinding housing 101. An opening and closing plate 301 is movably installed at the bottom of the maintenance plate 3. A waste chip box 105 is fixedly installed at the bottom of the steel pipe housing 104. A collection box 106 is slidably installed inside the waste chip box 105. Sound insulation cotton 109 is fixedly installed inside both the grinding housing 101 and the steel pipe housing 104.

[0027] In use, the grinding housing 101 is mounted on the outside of the grinding wheel of the equipment, and the steel pipe housing 104 is mounted inside the fixed seat of the steel pipe. When the equipment drives the grinding wheel to descend, the docking cover 102 at the bottom of the grinding housing 101 docks with the top of the steel pipe housing 104. Through the cooperation of the grinding housing 101, the docking cover 102, and the steel pipe housing 104, the entire grinding area can be closed, preventing dust generated during grinding of the steel pipe from flowing into the air. This closed-loop design significantly improves the dust reduction quality during steel pipe grinding. The waste shavings flow into the waste shavings bin 105, and the collection box 106 collects the waste shavings in the waste shavings bin 105. The collection box 106 facilitates the centralized processing of the collected waste shavings by the staff later. The disassembly of the maintenance plate 3 facilitates the maintenance and replacement of the grinding wheel by the staff later. The opening and closing plate 301 allows the staff to observe and understand the status of the steel pipe during grinding. The sound insulation cotton 109 increases the sound insulation function of the device. The sound insulation cotton 109 can block and reduce the noise generated during grinding, thereby reducing the noise during the grinding of the steel pipe.

[0028] Example 2

[0029] Based on Example 1, such as Figure 4-5 As shown, the filtration mechanism 2 includes a filter tank 201, a dust extraction pipe 203 is fixedly installed at the bottom of the filter tank 201, a dust extraction fan 204 is fixedly installed at the top of the filter tank 201, an assembly ring seat 206 is fixedly installed at the top inside the filter tank 201, a filter element 205 is installed in the internal thread of the assembly ring seat 206, and a closed ring plate 202 is assembled on the front of the filter tank 201.

[0030] In use, the filter canister 201 is installed on the front of the grinding housing 101. The dust extraction pipe 203 at the bottom of the filter tube 201 is fixedly connected to the docking cover 102. The dust extraction fan 204 at the top of the filter canister 201 can extract the dust generated during the grinding of the steel pipe through the dust extraction pipe 203. The filter element 205 is fixedly installed inside the filter canister 201 through the assembly ring seat 206. The filter element 205 can filter the dust entering the filter canister 201. The filtered gas is discharged into the air through the exhaust fan 204, thereby achieving the filtration of dust during the grinding of the steel pipe and improving the efficiency of dust reduction during the grinding of the steel pipe. The closing ring plate 202 can close and seal the front of the filter canister 201, and the opening of the closing ring plate 202 facilitates the cleaning and replacement of the filter element 205 by the staff.

[0031] like Figure 2-3 As shown, both sides of the docking cover 102 and the steel pipe shell 104 are fixedly installed with ring pipes 103.

[0032] When in use, the ring pipe 103 increases the coverage area of ​​the docking cover 102 and the steel pipe shell 104 respectively. By increasing the coverage area, the flow of dust and ash through the gap between the docking cover 102 and the steel pipe shell 104 and the steel pipe can be reduced.

[0033] like Figure 4 As shown, both sides of the filter tank 201 are fixedly installed with fixing plates 207, and both sides of the closed ring plate 202 are fixedly installed with assembly plates 208 that cooperate with the fixing plates 207.

[0034] In use, when the closed ring plate 202 is assembled on the front of the filter tank 201, the mounting plate 208 and the fixing plate 207 are aligned, and the mounting plate 208 is connected and fixed to the fixing plate 207 by bolts. Thus, the closed ring plate 202 can be installed and fixed by the fixing plate 207 and the mounting plate 208, and it is also convenient for the staff to disassemble the closed ring plate 202 later.

[0035] like Figure 6 As shown, a first mounting bracket 4 is fixedly installed on the other side of the grinding housing 101, and a second mounting bracket 401 is fixedly installed on both sides of the steel pipe housing 104.

[0036] In use, the first mounting bracket 4 can be used to install and fix the grinding housing 101, and the second mounting bracket 401 can be used to install and fix the steel pipe housing 104, which increases the convenience of installation of the grinding housing 101 and the steel pipe housing 104 and improves the stability during use.

[0037] like Figure 2 As shown, a limit plate 303 is rotatably installed on the lower side of one side of the grinding housing 101, and a pull rod 302 is fixedly installed on the lower side of the opening and closing plate 301.

[0038] When in use, when one end of the limiting plate 303 is rotated to the top, it can limit and lock the bottom of the opening and closing plate 301. The limiting plate 303 ensures the stability of the opening and closing plate 301 when closed. The pull rod 302 facilitates the operation of the opening and closing plate 301 by the staff, so that the staff can open the opening and closing plate 301 to observe and understand the grinding status of the steel pipe.

[0039] like Figure 2-3 As shown, a drawer panel 107 is fixedly installed on the front of the collection box 106, and a pull ring 108 is fixedly installed on the front of the drawer panel 107.

[0040] In use, the drawer plate 107 can limit the installation of the collection box 106, and the pull ring 108 on the front of the drawer plate 107 facilitates the operation of the staff to pull out and open the collection box 106.

[0041] Working principle: The grinding housing 101 is installed outside the grinding wheel of the equipment, and the steel pipe housing 104 is installed on the steel pipe tooling frame. When the grinding wheel descends, it will drive the grinding housing 101 to descend, thereby connecting the docking cover 102 at the bottom of the grinding housing 101 with the steel pipe housing 104. The docking can close the entire structure when the grinding wheel grinds the steel pipe. The overall closure can reduce dust during the grinding of the steel pipe. The overall closure improves the quality of dust reduction during the grinding of the steel pipe. The sound insulation cotton 109 can provide sound insulation and noise reduction during the grinding of the steel pipe. The dust extraction fan 204 and the dust extraction pipe 203 work together to extract the dust generated during grinding, and filter and purify the extracted dust through the filter tank 201 and the filter element 205.

[0042] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
