Anti-freezing device of gas circuit

Abstract

The invention discloses an anti-freezing device of a gas circuit. The anti-freezing device comprises a cabinet body, an air compressor, a fan, a heating chamber, an air inlet pipe and an air outlet pipe, wherein the air compressor, the fan and the heating chamber are all arranged in the cabinet body, the fan is respectively connected with the air compressor and the heating chamber through air pipes, the air inlet pipe penetrates through the cabinet body and is connected with the air compressor, the heating chamber is connected with one end of the air outlet pipe, the other end of the air outlet pipe penetrates through the cabinet body and is connected with the external drill gas circuit, and a plurality of heating pipes are arranged in the heating chamber. The anti-freezing device further comprises a water-separating gas filter, and the water-separating gas filter is arranged between the fan and the heating chamber; various gas control elements maintain a temperature of more than 0 DEG C and are not frozen or blocked under a low-temperature environment, it is guaranteed that a normal working temperature is kept under the low-temperature environment, and working efficiency of a drill is guaranteed. According to the anti-freezing device, sealed integrated components are adopted in the heating pipes, no dangerous gases are generated, sparkles cannot be produced, and therefore an anti-explosion effect is achieved.

Description

technical field [0001] The invention relates to an antifreeze mechanism, in particular to an air circuit antifreeze device. Background technique [0002] In oil drilling, the drilling tool is driven to break the rock, drill into the ground, and drill a wellbore with a specified depth for the oil or gas extraction machine to obtain oil or natural gas. A commonly used oil drilling rig generally has eight systems: including lifting system, rotating system, drilling fluid circulation system, transmission system, control system, power drive system, drilling rig base, drilling rig auxiliary equipment system, with tripping ability, rotary drilling Ability, cycle washing ability. Modern oil drilling rigs are linkage units of multiple working machines, requiring various mechanisms and systems to be organically combined into a unified whole, and to work accurately, coordinately and efficiently, a sensitive, accurate, safe and reliable control system is necessary. Small and portable ...

AI Technical Summary

Problems solved by technology

[0003] Although the air control is widely used, there are still some defects. For example, in the low temperature environment, the air control components are easy to be frozen, which slows down the transmission speed of the air control and reduces the efficiency of the drilling rig.
