Abstract
The utility model relates to a cage-type internal heater, which is characterized in that: the internal heater consists of a cage-type bracket, an asbestos blanket, a heating blanket, a connecting rod and roller wheels; the asbestos blanket and the heating blanket are arranged outside the cage-type bracket; the connecting rod is connected with a circle center column of the cage-type bracket; and two ends of the cage-type bracket are provided with the roller wheels. The internal heater has the advantages of high heating efficiency and capability of regulating the heating under welding work conditions.
Description
Technical field
The utility model relates to a kind of cage internal heater, relate in particular to a kind of when solving pipeline-like container welded condition temperature requirement keep 200 ℃～400 ℃ cage internal heater, belong to the heater technical field.
Background technology
Boiler and pressure vessel manufacturing are in manufacture course of products, there is the part caliber welding under the operating mode less than the pipe type element product of 800mm, weld interpass temperature there is specific (special) requirements greater than 200 ℃, present heater means adopts the outer wall heating, be flame heat or electric infrared heating, belong to the discontinuity heating, be difficult to keep the constancy of workpiece temperature.
Summary of the invention
The purpose of this utility model provides a kind of efficiency of heating surface height, can heat the cage internal heater of regulation and control.
For realizing above purpose, the technical solution of the utility model provides a kind of cage internal heater, it is characterized in that, form by cage support, asbestos mat, heating blanket, coupling bar and roller, outside the cage support, be provided with asbestos mat and heating blanket, coupling bar is connected with the center of circle post of cage support, is provided with roller at cage support two ends.
Described cage support is cylindrical, and its diameter and two roller diameter sums equal the long pipeline internal diameter.
Described heating blanket is a ceramic electrical infrared heating blanket.
The utility model is by cage support and two groups of moulding beds that can roll flexibly that roller is synthetic; the ceramic electrical infrared heating blanket of configure dedicated on the moulding bed; always dress up internal heater with coupling bar; roller can be guaranteed the inwall of the light turnover long pipeline of this heater; coupling bar can be grown apart from operate heater and advance and retreat; ceramic electrical infrared heating blanket is by external special-purpose electrical control cubicles regulation and control; thereby add heat request by the pipeline body inwall welding procedure that realizes continuous constant temperature of being heated; wherein asbestos mat plays the insulation protection effect, contingent electric heating element and moulding bed short circuit or electric leakage accident when preventing the earthenware fragmentation.
The utility model has the advantages that:
1. can realize the built-in heating of pipeline member, be particularly suitable for Φ
In≤ 800 pipe fitting, efficiency of heating surface height;
2. can do continual heating to workpiece, particularly can under the welding operating mode, heat regulation and control;
3. can improve welding job environment and welder's working condition;
4. other circle class article or occasion of heating in the present invention also can be used for carrying out.
Description of drawings
Fig. 1 is a kind of cage internal heater structural representation;
Fig. 2 is a kind of cage internal heater schematic diagram that is installed in the long pipeline.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Embodiment
As shown in Figure 1, be a kind of cage internal heater structural representation, described a kind of cage internal heater is made up of cage support 1, asbestos mat 2, heating blanket 3, coupling bar 4 and roller 5.
Asbestos mat 2, parcel heating blanket 3 are installed outside cage support 1, and described heating blanket 3 is the ceramic electrical infrared heating blanket of outsourcing, and coupling bar 4 is connected with the center of circle post 6 of cage support 1, at cage support 1 two ends hoop roller 5 is installed.
Described cage support 1 is cylindrical, and its diameter and two roller 5 diameter sums equal the long pipeline internal diameter.
As shown in Figure 2, for being installed in a kind of cage internal heater schematic diagram in the long pipeline, during use, the lead of heating blanket 3 is connected to the electrical control cubicles of outside, with coupling bar 4 the present invention is sent into to push away in the pipeline 7 and be rolled to the service position, the energising heating is the temperature adjustment temperature control also.
