Background

At present, most of the existing cutting guns only have an acetylene gas inlet and a high-pressure oxygen inlet, and when the cutting guns are used, the cutting guns are often stopped when the cutting guns are too high in temperature due to lack of cooling. This will affect the cutting progress and the production of the enterprise. Therefore, there is a need for an improved cutting torch, which reduces energy consumption and improves production efficiency.

The utility model discloses a continuous casting burning torch of bulletin number CN207857810U, including the rifle body, the inside fixedly connected with inlet tube of the rifle body, ordinary oxygen pipe, the acetylene trachea, hyperbaric oxygen pipe and outlet pipe, the port fixedly connected with connection cap of the rifle body, the water inlet has been seted up to the connection cap, ordinary oxygen gas port, the acetylene gas port, hyperbaric oxygen gas port and delivery port, the inlet tube, ordinary oxygen pipe, the acetylene trachea, equal fixedly connected with water supply connector respectively of hyperbaric oxygen pipe and outlet pipe, ordinary oxygen connects, the acetylene gas connects, hyperbaric oxygen connects and water outlet connector, the one end fixedly connected with cooling chamber of inlet tube is kept away from to water supply connector, ordinary oxygen connector keeps away from the gaseous mixing chamber of one end fixedly connected with of ordinary oxygen pipe, the one end fixedly connected with base of connecting the cap is kept away from to the rifle body, the one end fixedly connected with rifle. The utility model discloses a jet orifice has been seted up to the rifle mouth, and the rifle mouth is connected in the gas mixing chamber, and flame intensity is high, and cutting effect is good.

However, the above utility model patent documents still have disadvantages: the structure setting of this burning torch is limited to the cooling effect of burning torch, and cooling efficiency is low, can not reach high cooling effect.

SUMMERY OF THE UTILITY MODEL

Not enough to prior art exists, the utility model provides a portable emergent accident burning torch, this burning torch cooling efficiency is high, reaches high cooling effect, has prolonged the life of burning torch, and simple structure, convenient to carry.

The utility model discloses a realize through following technical scheme: the portable emergency accident cutting gun comprises a gun body, a water inlet pipe, a common oxygen pipe, an acetylene gas pipe, a high-pressure oxygen pipe and a water outlet pipe which are sequentially connected with the inside of the gun body in a penetrating manner, a gas mixing cavity and a cooling cavity which are arranged at one end in the gun body, and a gun nozzle fixedly connected with the lower end of the gun body through a base, wherein the gas mixing cavity penetrates through the cooling cavity, one ends of the water inlet pipe and the water outlet pipe are respectively communicated with the cooling cavity, the common oxygen pipe, the acetylene gas pipe and the high-pressure oxygen pipe are respectively communicated with the gas mixing cavity, the water inlet pipe and the water outlet pipe are formed by connecting a plurality of large-diameter pipes and small-diameter pipes end to end, and a plurality of baffle.

The base and the gun nozzle are made of high-temperature-resistant materials, and the gun nozzle is connected with the gas mixing cavity.

Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses inlet tube and outlet pipe adopt big pipe diameter pipe and little pipe diameter pipe head and the tail interval connection's respectively design, under equal flow, because the pipe diameter of little pipe diameter pipe is less, then the cooling water velocity of flow improves, and then heat transfer rate has been improved, and big pipe diameter pipe has guaranteed on the one hand that the cooling water flow resistance is unlikely to too big, need not to strengthen extra power when can making the cooling water get into little pipe diameter pipe and flow, and the cooling intracavity is from top to bottom along a plurality of baffling boards that week was equipped with, the flow and the area that the cooling water flows have been increased, and then heat transfer rate has been improved, thereby the cooling effect has been reinforceed, the cooling efficiency is high, the life of burning torch has been prolonged, and simple structure, and convenient.
