Description

Technical Field

[0001] The utility model relates to the technical field of dust removal devices, in particular to a dust removal system for a manual flame cutting machine. Background Technique

[0002] A large amount of scrap steel is generated during the steel production process. At present, scrap steel cutting usually adopts the flame cutting method for treatment. However, a large amount of harmful dust will be generated during the cutting process of the flame cutting machine, which not only damages the physical health of the surrounding personnel, but also affects the production environment.

[0003] In order to solve the above technical problems, the Chinese utility model patent with the authorization announcement number CN220862965U discloses a dust removal device for a continuous casting slab flame cutting machine. This solution covers the flame cutting machine with a dust removal hood, connects the dust removal hood to a vertical air duct, then connects the vertical air duct and the horizontal air duct to a moving trolley, the moving trolley is slidably connected to the upper open end of a ventilation trough, the air outlet section of the horizontal air duct is communicated with the upper open end of the ventilation trough, and the other end of the ventilation trough is connected to a dust removal device. During operation, the moving trolley drives the vertical air duct and the horizontal air duct to move in the ventilation trough, thereby driving the dust removal hood connected to the vertical air duct to move synchronously with the flame cutting machine, so that the dust removal hood always covers the cutting point. The dust generated by the flame cutting machine cutting the scrap steel is successively sucked into the dust removal device through the dust removal hood, the vertical air duct, the horizontal air duct and the ventilation trough, thereby treating the dust.

[0004] However, the applicant found deficiencies: there is an activity gap between the horizontal air duct and its air outlet section and the open end of the ventilation trough. In order to ensure that the dust will not leak from the activity gap, a sealing structure composed of a sealing belt and a guide roller is used in this solution to seal this activity gap. However, since the working temperature of the flame cutting machine can reach thousands of degrees Celsius, the dust will have a relatively high temperature. After the sealing belt is in long-term contact with the high-temperature dust, local damage will occur, resulting in subsequent dust leaking from the gap between the ventilation trough and the sealing belt, thus affecting the dust removal effect.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0034] Next, in combination with the accompanying drawings in the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0035] Please refer to Figure 1-2 , the present utility model provides a technical solution: a dust removal system for a manual flame cutting machine, including: a dust suction hood 13 and a dust collector 1 connected to the dust suction hood 13; a first conveying pipeline with one end connected to the outlet of the dust suction hood 13; a second conveying pipeline with one end connected to the inlet of the dust collector 1, and the first conveying pipeline and the second conveying pipeline are combined to form a dust pipeline for sending dust from the dust suction hood 13 into the dust collector 1; a moving component connected to the dust pipeline, and the moving component is used to drive the dust pipeline and the dust suction hood 13 to move synchronously with the flame cutting machine 14, so that the dust suction hood 13 covers the cutting point of the flame cutting machine 14 and collects the generated dust;

[0036] Adopting the above technical solution can ensure that the dust suction hood 13 can move synchronously with the flame cutting machine 14 and there will be no dust leakage. When in use, when the flame cutting machine 14 starts to run, the moving component drives the first conveying pipeline, the second conveying pipeline and the dust suction hood 13 to move synchronously, realizing the synchronous operation of the dust suction hood 13 and the flame cutting machine 14, and collecting the dust generated by the flame cutting machine 14. Since the moving component drives the first connecting pipe and the second connecting pipe to move synchronously, there will be no movable gap between the first connecting pipe and the second connecting pipe, so there will be no problem of poor sealing effect and resulting in dust leakage, and there is no need to set up a complex sealing structure.

[0037] As Figure 1 and Figure 2 shown, in this embodiment, the moving component includes: a connecting body 7 for fixing the first conveying pipeline and the second conveying pipeline; wheels 9 provided at the bottom end of the connecting body 7; a track frame 10 cooperating with the wheels 9, and the track frame 10 is parallel to the cutting track 15; a servo motor 8 for driving the wheels 9 to rotate, and the servo motor 8 is provided at the bottom end of the connecting body 7;

[0038] Adopting the above technical solution can drive the first conveying pipeline, the second conveying pipeline and the dust suction hood 13 to move. When the flame cutting machine 14 starts to run, the connecting body 7 realizes synchronous operation with the flame cutting machine 14 through the transmission of the wheels 9 and the servo motor 8. The connecting body 7 drives the first conveying pipeline with the dust suction hood 13 to move synchronously with the flame cutting machine 14, and collects the dust generated by the flame cutting machine 14. Since the track frame 10 and the connecting body 7 are laid on the ground, compared with the prior art erected in the air, the structure is simpler and it is convenient for layout and maintenance.

[0039] As Figure 1As shown in the figure, in this embodiment, the first conveying pipeline includes: a pluggable pipeline 12 with one end connected to the outlet of the dust suction hood 13; a first fixed steel pipe 11 with one end connected to the other end of the pluggable pipeline 12, and the other end of the first fixed steel pipe 11 is connected to the other end of the second conveying pipeline;

[0040] As Figure 2 shown in the figure, in this embodiment, the second conveying pipeline includes: a second fixed steel pipe 3 with one end connected to the inlet of the dust collector 1; a hose 4 with one end connected to the other end of the second fixed steel pipe 3; a third fixed steel pipe 5 with one end connected to the other end of the hose 4, and the other end of the third fixed steel pipe 5 is connected to the first fixed steel pipe 11;

[0041] Adopting the above technical solution can ensure that the soot can be sent from the dust suction hood 13 into the dust collector 1. During operation, the dust collector 1 sucks the soot through the dust suction hood 13 into the pluggable pipeline 12, and then successively passes through the first fixed steel pipe 11, the third fixed steel pipe 5, the hose 4 and the second fixed steel pipe 3 into the dust collector 1, and the dust collector 1 processes the soot.

[0042] Furthermore, as Figure 1 and Figure 2 shown in the figure, in this embodiment, the hose 4 is a plastic hose with transparent inner embedded steel wires, and the length of the hose 4 is greater than or equal to the stroke of the flame cutting machine 14; the dust suction hood 13 is made of transparent material, and the dust collector 1 is preferably a cartridge dust collector;

[0043] Adopting the above technical solution ensures that the hose 4 can meet the usage requirements. Since the dust collector 1 is basically stationary, an inextensible hose 4 is added between the dust collector 1 and the connecting body 7. The length of the hose 4 can ensure the requirements of the running distance of the flame cutting machine 14. The reason why the hose 4 is inextensible is that the expansion and contraction of the extensible hose 4 under negative pressure will cause the length to contract, reducing the stroke requirements of the flame cutting machine 14. The hose 4 ensures the running distance of the flame cutting machine 14 by increasing or decreasing the vertical section. The dust suction hood 13 is made of transparent material, which can facilitate observing the operation of the flame cutting machine 14 from the outside.

[0044] As Figure 1 shown in the figure, in this embodiment, the connecting body 7 is a self-balancing square cylinder body, and the self-balancing square cylinder body is provided with a hollow pipe. One end of the hollow pipe is connected to the third fixed steel pipe 5, and the other end of the hollow pipe is connected to the first fixed steel pipe 11; a first quick joint 2 is provided between the inlet of the dust collector 1 and the second fixed steel pipe 3, and a second quick joint 6 is provided between one end of the third fixed steel pipe 5 and one end of the hollow pipe. The pluggable pipeline 12 and the dust suction hood 13 are fixed on the first fixed steel pipe 11 through a positioning pin 16;

[0045] Adopting the above technical solution ensures that the first fixed steel pipe 11 and the third fixed steel pipe 5 can communicate with each other, so as to ensure that the soot can pass through the dust suction hood 13, the pluggable pipe 12, and then successively pass through the first fixed steel pipe 11, the hollow pipe of the balanced square cylinder, the third fixed steel pipe 5, the hose 4 and the second fixed steel pipe 3 and enter the dust collector 1.

[0046] Further, as Figure 1 and Figure 2 shown, in this embodiment, 4 wheels 9 are provided and symmetrically arranged. The track frame 10 includes two tracks, and the track frame 10 and the flame cutting track 15 are laid on the factory floor;

[0047] Adopting the above technical solution ensures that the connecting body 7, that is, the self-balancing square cylinder, can move stably. The weight of the self-balancing square cylinder does not exceed 15 kg, which is convenient for personnel to move. The self-balancing square cylinder is driven by the wheels 9 and the servo motor 8 to run synchronously with the flame cutting machine 14. Since 4 wheels 9 are provided, a stable support can be formed for the self-balancing square cylinder to prevent the self-balancing square cylinder from tilting and shaking.

[0048] Optionally, in this embodiment, a second quick connector 6 is provided at one end of the third fixed steel pipe 5. The second quick connector 6 is connected to the first fixed steel pipe 11. The connecting body 7 is a movable platform, and a fixture for fixing the third fixed steel pipe 5 and the first fixed steel pipe 11 is provided on the movable platform;

[0049] Adopting the above technical solution can directly connect the third fixed steel pipe 5 and the first fixed steel pipe 11. Since the function of the connecting body 7 is to ensure that the third fixed steel pipe 5, the first fixed steel pipe 11 and the dust suction hood 13 can move synchronously with the flame cutting machine 14, the connection relationship between the third fixed steel pipe 5 and the first fixed steel pipe 11 is not strictly limited. The third fixed steel pipe 5 and the first fixed steel pipe 11 can be directly connected or indirectly connected, as long as the third fixed steel pipe 5 and the first fixed steel pipe 11 can form a complete conveying route, that is, the connecting body 7 plays a role of movement and support.

[0050] Working principle: When the flame cutting machine 14 starts to run, the connecting body 7 is driven by the wheels 9 and the servo motor 8 to run synchronously with the flame cutting machine 14. The connecting body 7 drives the pluggable pipe 12 with the dust suction hood 13 to run synchronously with the flame cutting machine 14 to collect the dust generated by the flame cutting machine 14. Since the dust collector 1 is basically stationary, the non-retractable hose 4 between the dust collector 1 and the connecting body 7 is added. The length of the hose 4 can meet the requirements of the running distance of the flame cutting machine 14. The reason why the hose 4 is non-retractable is that the retraction of the retractable hose 4 under negative pressure will cause the length to shrink, reducing the travel requirements of the flame cutting machine 14. The running distance of the flame cutting machine 14 is ensured by increasing or decreasing the vertical section of the hose 4. The hose 4 is generally a plastic hose 4 with transparent inner embedded steel wires. Since the connecting body 7 drives the third fixed steel pipe 5 and the first fixed steel pipe 11 to move synchronously, there will be no moving gap between the third fixed steel pipe 5 and the first fixed steel pipe 11. Therefore, there will be no problem of poor sealing effect and dust leakage. Correspondingly, there is no need to set up a complex sealing structure.

[0051] Thus, a series of operations are completed. The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0052] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present invention. Any reference signs in the claims should not be regarded as limiting the claimed invention.
