Description

Technical Field

[0001] The utility model relates to the technical field of cutting protection, in particular to a flame cutting anti-splash device. Background Art

[0002] Flame cutting is a common method for rough machining steel plates. Traditionally, flame cutting used acetylene, later methane, and now natural gas. Due to its abundant reserves, low price, and pollution-free properties, natural gas has become the preferred method for flame cutting. The flame cutting process produces harmful gases and high-temperature oxide slag, posing significant safety risks. Handling the torch can easily cause burns to the operator, requiring a precise holding angle to avoid burns. The presence of flammable materials in the environment can also pose a significant risk.

The annular shield and the refractory cylinder can be conveniently disassembled by using a clamping seat and a clamping sleeve, thereby solving the problem of high-temperature oxide slag splashing in the existing flame cutting process.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is: a flame cutting anti-splash device, including a cutting nozzle, an annular holder is provided on the upper part of the cutting nozzle, a sleeve is clamped on the outer side of the holder, a radial connecting frame is provided on the outer side of the sleeve, a transparent annular shield is provided at the outer end of the connecting frame, and a detachable refractory cylinder is provided at the bottom of the annular shield.

[0005] To further optimize this technical solution, a plurality of axial slots are provided on the outside of the card base, one end of the slot is connected to one axial end of the card base, and the other end of the slot is connected to an arc-shaped card slot, and a card connection position is provided at the end of the card slot away from the slot, and a card connection block is provided at the position corresponding to the card sleeve and the card connection position, the width of the card connection block is equal to the width of the slot, and the axial height of the card connection block is equal to the axial height of the card connection position.

[0006] To further optimize the technical solution, a downwardly protruding spring piece is provided at the axial top of the engaging position, and a groove is provided at the position of the engaging block corresponding to the spring piece.

[0007] To further optimize this technical solution, a magnetic ring is provided on the outer side of the annular shield, and a ferromagnetic portion is provided on the top edge of the refractory cylinder.

[0008] Compared with the prior art, the utility model has the following advantages:

[0009] 1. The use of a card holder and a card sleeve can facilitate the disassembly of the annular shield and the refractory tube, which is safe and convenient to use;

[0010] 2. Fix the card holder on the top of the cutting nozzle, and insert the card sleeve from the side of the cutting nozzle into the outside of the card holder. When clamping, first insert the clamping block into the slot. When it reaches the slot, rotate the card sleeve to screw the clamping block into the clamping position. When different working conditions are required, the annular shields of different diameters can be replaced for easy operation.

[0011] 3. The refractory tube can be easily disassembled through the provided magnetic ring, which not only increases the operational safety but also makes it more convenient to use. BRIEF DESCRIPTION OF THE DRAWINGS
