Description

Technical Field

[0001] This utility model relates to the field of flame cutting equipment technology, and more specifically to a dual-nozzle iron powder injector for flame cutting machines. Background Technology

[0002] In the steel metallurgical industry, flame cutting machines are commonly used to cut various types of steel. However, standard flame temperatures often fail to achieve ideal cutting results when handling special steels and extra-large cross-sections. In such cases, an iron powder injection device is needed. This device uses the additional heat generated by the combustion of iron powder to raise the temperature of the cutting flame, thereby meeting the requirements for high-temperature cutting.

[0003] Currently, traditional iron powder injectors have the following main problems:

[0004] 1. Traditional iron powder injectors have a rudimentary internal channel design and lack meticulous planning, resulting in uneven distribution of iron powder during the injection process. This unevenness leads to inconsistent iron powder concentration in the cutting area. Some areas have too much iron powder, resulting in waste, while other areas have insufficient iron powder, which cannot adequately assist the cutting process. This results in unstable cut surface quality, with defects such as high roughness and irregular texture, affecting the processing accuracy and surface quality of the cut steel.

[0005] 2. Many existing injectors have improperly set spray angles, which prevents them from effectively spraying iron powder to the cutting flame, resulting in low iron powder utilization and serious waste of resources.

[0006] 3. Existing spraying supports typically only have one nozzle, which cannot meet the iron powder supply requirements for large-section cutting. Insufficient iron powder supply during large-section cutting leads to low cutting efficiency, poor cutting quality, and failure to meet production requirements. Although some imported equipment is equipped with multiple nozzles, these nozzles are usually fixed, making disassembly and assembly cumbersome and hindering quick replacement and maintenance. This not only increases production downtime and maintenance costs but also affects production continuity and efficiency.

[0007] Therefore, developing a dual-nozzle iron powder injector for flame cutting machines that can meet the requirements of large-section cutting and is easy to disassemble and clean is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0008] In view of this, the present invention provides a dual-nozzle iron powder injector for flame cutting machines that can meet the requirements of large-section cutting and is easy to disassemble and clean.

[0009] To achieve the above objectives, the present invention adopts the following technical solution:

[0010] The dual-nozzle iron powder injector for flame cutting machines includes:

[0011] The main body has multiple parallel powder spraying channels inside;

[0012] The powder outlet pipe has multiple parallel installation channels on its top, which are connected to the powder outlet end of the powder spraying channel. The installation channels are inclined upwards, and the powder outlet pipe can be detachably installed in the installation channels. The inner cavity of the powder outlet pipe near the powder spraying channel is flared outwards.

[0013] The beneficial effect of adopting the above technical solution is that, by setting up multiple parallel powder spraying channels and multiple powder outlet pipes, this utility model can provide sufficient iron powder flow rate to meet the iron powder supply requirements during large-section cutting, thereby improving cutting efficiency.

[0014] Preferably, both the powder spraying channel and the installation channel are provided in twos. The dual-channel design can increase the amount of iron powder conveyed, better meeting the iron powder supply requirements during large-section cutting; at the same time, it can make the iron powder spraying more stable, reduce spraying interruptions caused by blockage or failure of a single channel, and improve the continuity and stability of the cutting process.

[0015] Preferably, bolts are connected to the side of the main body, the bolts passing through the interior of the main body and connecting to the powder outlet pipe located in the installation channel. Connecting the powder outlet pipe and the main body with bolts ensures stable installation of the powder outlet pipe during spraying, preventing loosening or detachment due to vibration or impact. The bolt connection method is simple and easy to operate, facilitating quick replacement or maintenance of the powder outlet pipe, reducing downtime, and improving equipment maintenance efficiency.

[0016] Preferably, the angle between the powder outlet pipe and the surface of the body is 140°. A reasonable spray angle can prevent iron powder from being sprayed into non-cutting areas, reduce resource waste, and reduce pollution to the surrounding environment.

[0017] Preferably, the installation channel is provided with an installation step, and the powder outlet pipe abuts against the installation step. The installation step provides stable support for the powder outlet pipe, ensuring accurate positioning of the powder outlet pipe during installation and avoiding uneven spraying due to installation errors.

[0018] Preferably, a bracket is detachably mounted on the top of the main body, and the bracket is connected to the cutting torch. By connecting the bracket to the cutting torch, the iron powder injector and the cutting torch of the flame cutter can be tightly integrated to form an integrated cutting system, improving the overall integrity and coordination of the equipment.

[0019] Preferably, a connector is connected to the powder inlet of the powder spraying channel, which connects both the powder spraying channel and the powder spraying pipe. The connector design facilitates the connection between the powder spraying channel and the powder spraying pipe, allowing users to adjust the iron powder conveying path according to actual needs and improving the versatility and flexibility of the equipment.

[0020] Preferably, the connector is a compression fitting type connector.

[0021] As can be seen from the above technical solution, compared with the prior art, this utility model discloses a dual-nozzle iron powder injector for a flame cutting machine, the beneficial effects of which are:

[0022] (1) By setting up multiple powder spraying channels and multiple powder outlet pipes arranged in parallel, sufficient iron powder flow rate can be provided to meet the iron powder supply requirements during large-section cutting, thereby improving cutting efficiency;

[0023] (2) The inner cavity of the powder outlet is designed as an outward-expanding funnel shape, which can make the iron powder more evenly distributed during spraying, avoid local iron powder accumulation or insufficient iron powder, thereby improving the quality of the cut surface.

[0024] (3) The powder outlet pipe adopts a detachable installation method, combined with the upward inclined installation channel, which facilitates quick replacement and cleaning of the nozzle, reducing maintenance time and cost;

[0025] (4) The installation channel is inclined upward, which can ensure that the iron powder is sprayed into the cutting flame at a suitable angle, improve the utilization rate of iron powder, and reduce resource waste and environmental pollution. Attached Figure Description
