Description
Technical field
The utility model is related to cable protecting device, especially a kind of bimetallic tube for protecting cable, for high temperature
The cable in region is protected.
Background technology
In industrial production, due to plant designing reason, some cables have to pass through from high-temperature area, especially in refining
In the fields such as iron, steel-making, forging.When cable laying is around such as high temperature forging machine, the aging speed of cable can be accelerated, always
The cable of change its insulating properties can be had a greatly reduced quality, and even the production accidents such as short circuit are led to when serious.Meanwhile, when temperature is too high
When, the crust of cable can be damaged, and cause the serious consequences such as electric leakage, short circuit.Therefore, these are needed by the cable of high-temperature area
Certain safeguard procedures are carried out, the safeguard measure to the cable in high-temperature area is single in the prior art, typically in electricity
The outside suit high temperature protection set of cable, high temperature protection set is made up of fire proofings such as glass fibre, silicon rubber.Such high-temperature electric
Cable protection set simply individually improves fire resistance of the cable in high-temperature area, but does not solve cable fundamentally in high temperature
The problem that aging speed is accelerated in area, meanwhile, such high-temperature cable protective case can be with the crust one of cable when temperature is too high
And be damaged, it is difficult to ensure the Electrical Safety of high-temperature area.
Utility model content
The utility model technical issues that need to address are to provide one kind prevents cable from aging, damage occurring in high-temperature area
Bad double-deck cable protection pipe.
In order to solve the above technical problems, the technical scheme that the utility model is used is：
A kind of bimetallic tube for protecting cable, including an inner tube being used for through cable, are also sleeved on including one
An outer tube for cooling chamber is formed between inner tube outside and inner tube, the closed at both ends of cooling chamber, the front end of cooling chamber is provided with confession
Cooling agent injection cooling chamber enters pipe, and there is a coolant outlet rear end of cooling chamber by one section of connection by metal hose, inner tube with
The same position of the centre of outer tube is provided with the bending section of metal hose composition.
Technical solutions of the utility model further improvement is that：Cooling agent is liquid nitrogen or dry ice particles, coolant outlet
For tubaeform.
Technical solutions of the utility model further improvement is that：Cooling agent is water, and coolant outlet is connected with waste liquid pool.
Technical solutions of the utility model further improvement is that：The outside of outer tube is uniformly fitted with some triangle branch
Frame.
Technical solutions of the utility model further improvement is that：The outer wall of outer tube is coated with caution slogan, inner tube it is interior
Wall is coated with fire retardant.
By adopting the above-described technical solution, the technological progress that the utility model is obtained is：
The utility model is a kind of bimetallic tube for protecting cable, and inner tube has for cooling agent flowing with outer tube middle setting
Cooling chamber.It is such to be designed to be isolated outside thermal source with cable, cable is fundamentally solved in high-temperature region
Aging and damaged problem is susceptible in domain, the Electrical Safety in high-temperature area has fully been ensured.Inner tube of the present utility model
Be additionally provided with the bending section that metal hose is made with the stage casing of outer tube, when being applied to different scenes can flexibly bending, it is full
The demand of sufficient various working.
The utility model can be stronger according to the different cooling agent of the different choice of field working conditions, adaptability, is given birth to meeting
Produce on the basis of field demand, cooling agent consumption is reduced as far as possible, the economy that equipment is used is protected.
When cooling agent of the present utility model uses liquid nitrogen or dry ice particles, the exit design flue of cooling agent,
And coolant outlet is arranged on an end for metal hose.Nitrogen that such design will can be produced in cooling chamber or
Carbon dioxide is used to radiate other equipment, material is obtained secondary utilization, has saved the use cost of equipment.
Flame-retardant layer is provided with the inwall of inner tube of the present utility model, cable is reduce further and is occurred in use
The risk of accident.Caution slogan is coated with the outer wall of outer tube, the security during equipment use is further ensured.
Some A-frames are fitted with outer tube of the present utility model, make the easier for installation of equipment.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Wherein, 1, outer tube, 2, inner tube, 3, bending section, 4, into pipe, 5, coolant outlet, 6, A-frame.
Specific embodiment
The utility model is described in further details with reference to embodiment：
As shown in figure 1, the utility model is a kind of bimetallic tube for protecting the cable in high-temperature area work, main bag
One is included for the inner tube 2 through cable, an outer tube 1 is set with outside inner tube 2.Inner tube 2 and the middle of outer tube 1 form one two
The cooling chamber that end seal is closed.Cooling chamber is wrapped in around inner tube 2.Inner tube 2 and outer tube 1 are made by metal material.In view of making
May need to be applied to various working during, cable is not necessarily laid according to straight line, and the utility model is in bilayer
The middle setting of pipe has a bending section 3 that one or more is made up of metal hose, metal hose and inner tube 2 and outer tube 1 it is straight
Section is tightly connected.Metal hose is the Universal pipe of cascade type.
One is sleeved on an outer tube for cooling chamber 1 is formed between the outside of inner tube 2 and inner tube 2, the closed at both ends of cooling chamber,
The front end of cooling chamber is provided with the entrance pipe 4 that cooling chamber is injected for cooling agent, and the rear end of cooling chamber is connected by one section of metal hose
