Description
Technical Field
[0001] This utility model relates to the field of environmental protection and dust removal technology, and more specifically, to a dust removal device for cutting waste steel billets. Background Technology
[0002] Steelmaking plants inevitably generate scrap steel during production, which is then recycled back into the furnace. Because scrap steel is too large to be added to the converter as a whole, it needs to be cut into billets before being added. This billet cutting process inevitably produces fumes, polluting the environment.
[0003] Current cutting methods rely entirely on smokeless gas collection for flue gas treatment. The treatment process typically employs a fixed cutting pool, where a fixed dust collection hood is connected to a fixed dust collector via pipes. The steel billet needs to be hoisted into the cutting pool each time using an overhead crane. The entire system consists of the fixed dust collection hood, pipes, and dust collector, making it a fixed dust collection system. When not in use, it occupies a large area and incurs high costs; furthermore, due to its fixed location, the dust collection efficiency is relatively poor. Utility Model Content

[0028] In response to the aforementioned problems, such as poor dust collection efficiency, large floor space, and high cost of the existing fixed dust collection device, a dust removal device for scrap steel billet cutting is proposed.
[0029] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0030] To illustrate the dust removal device for cutting scrap steel billets provided by this utility model Figure 1 The structure of a dust removal device for cutting scrap steel billets according to an embodiment of the present invention is shown; Figure 2 It shows Figure 1 The side structure; Figure 3 The structure of the mobile trolley according to an embodiment of the present invention is shown; Figure 4 A top view of the mobile trolley on the track according to an embodiment of the present invention is shown; Figure 5 It shows Figure 4 The structure of the AA part; Figure 6 The structure of a single dust collector according to an embodiment of the present invention is shown; Figure 7 It shows Figure 6 The side structure.
[0031] like Figures 1 to 7 As shown in the figure, the dust removal device for cutting scrap steel billets provided by this utility model mainly includes a dust removal moving mechanism and a dust collection mechanism; wherein, the dust removal moving mechanism includes a track 11 set on one side of the steel billet placement position 3, a moving trolley 12 set on the track 11, and a single dust collector 13 set on the top of the moving trolley 12; the track 11 is set along the steel billet cutting direction; the dust collection mechanism includes a pipe 21 connected to one side of the single dust collector 13 and a dust collection hood 22 set at the port of the pipe 21; the dust collection hood 22 is set above the steel billet cutting position.
[0032] Specifically, the billet placement position 3 is used to place the billet 8 to be cut. The cutting method can be flame cutting or any other cutting method, which is not particularly limited in this utility model. When cutting the billet 8, the moving trolley 12 moves in the same direction as the billet cutting position on the track 11 to ensure that the dust collection hood 22 is always above the billet cutting position. The individual dust collector 13 can be any type of dust collector in the prior art, which is not particularly limited in this utility model. The individual dust collector 13 generally mainly includes a shell 131, a support 132 set at the bottom of the shell 131, a fan 133 and a pulse valve 134 set on the upper outer wall of the shell 131, etc. Since the individual dust collector 13 is a mature existing device, it will not be described in detail in this utility model.
[0033] By setting a track 11 on one side of the billet placement position 3, setting a moving trolley 12 on the track 11, setting a single dust collector 13 on the top of the moving trolley 12, and connecting a dust collection hood 22 to the single dust collector 13 through a pipe 21, and setting the dust collection hood 22 above the billet cutting position, the dust collection point can move with the change of the billet cutting position, so that the dust suction port is closer to the dust generation position and the dust collection effect is good. Moreover, the requirements for the single dust collector 13 are low, only a single dust collector 13 with a small air volume is required, the load capacity is low, the size of the dust collection hood 22 is also smaller, and there is no need to connect a large pipe, thus reducing costs.

[0039] Specifically, a double track and four wheel supports are used, with two pairs of driving wheels and driven wheel sets installed under each wheel support, which makes the moving trolley 12 move more smoothly on the track 11.
[0040] As a preferred embodiment of this utility model, a proximity switch 5 is provided at the preset parking position of the track 11; the proximity switch 5 is signal-connected to the reduction motor 126.
[0041] Specifically, the proximity switch 5, also known as the proximity sensor, is connected to the geared motor 126 via a signal connection, which controls the mobile trolley 12 to stop at a preset parking space. The preset parking space can be set according to actual needs, and this invention does not impose any particular limitation on it.
[0042] As a preferred embodiment of this utility model, a power source (not shown in the figure) is provided at the front or rear end of the billet placement position 3; a cable (not shown in the figure) is connected to the power source; the power supply end of the cable is connected to the geared motor 126 and the individual dust collector 13.

[0048] As a preferred embodiment of this utility model, a pipe support 7 is provided on the movable trolley 12; the pipe support 7 is located at the lower part of the horizontal section 211 of the pipe 21.
[0049] Specifically, the horizontal section 211 of the pipe 21 rests on the pipe support 7. The two are not fixed together, and there is a relative displacement between them. When the pipe 21 is heated, the thermal expansion generated can be offset by free displacement, thus preventing it from being pulled apart.
[0050] As a preferred embodiment of this utility model, the bottom of the pipe support 7 and the bottom of the individual dust collector 13 are both welded to the top of the mobile trolley 12.
[0051] Specifically, the supports for the track 11, the mobile trolley 12, the pipe support 7, and the individual dust collector 13 are preferably steel structures, and the bottom of the pipe support 7 and the bottom of the individual dust collector 13 are preferably, but not limited to, welded to the top of the mobile trolley 12.
