Abstract
The utility model provides a heat treatment device of a solar heat collector pipe, which comprises a furnace end (1) and a control valve (2), wherein the furnace end (1) adopts an integrated-type heating annealing belt (3) with multiple furnace ends in parallel and no flame clearance, and the heating annealing belt (3) is of a belt-shaped structure. The heat treatment device has advantages of large flame range and good stress relieving effect.
Description
Technical field
The utility model relates to solar energy heating pipe manufacturer field, relates in particular to a kind of thermal treatment unit of solar energy heat collection pipe.
Background technology
The structure of solar energy glass pipe designs for double-layer glass tube; And the space between the two-layer pipe is a vacuum state; In manufacturing processed; At first outer tube one end is sealed processing, weld an elongated glass tail pipe at closedend then, for use in the air that from tail pipe, extracts in the following process between the two-layer pipe.
Glass tail pipe after the welding is because the bigger stress of local existence need carry out the destressing handling return after welding, and the present mode that adopts is that the glass tail pipe after the welding is about the liquefied gas flame furnace about 15mm through 3 ~ 5 bores successively; And these liquefied gas flame furnaces are arranged on the same straight line, between adjacent two the spacing about 15mm are arranged, when carrying out anneal; Receive the little restriction of flame furnace bore, flame is less, also owing to have the gap between the flame furnace; Cause annealing temperature not continue, the flame heating that the tail pipe weld is received is inhomogeneous, and stress relieving is not thorough; Fracture causes the increase of cost and unnecessary waste easily.
Summary of the invention
The technical problem that the utility model will solve is to the existing in prior technology weak point, and the thermal treatment unit of the solar energy heat collection pipe that a kind of flame scope is big, destressing is effective is provided.
The technical solution of the utility model is; The thermal treatment unit of following a kind of solar energy heat collection pipe is provided; Comprise burner and by-pass valve control, described burner adopts a plurality of burners side by side and do not have the integral type heating anneal band in flame gap, and described heating anneal band is zonal structure.
After adopting above scheme; The utility model changes original flame furnace single, independent and that intermittence is arranged in order into that stone or metal plate for standing a stove on as a precaution against fire is big, the flame scope is wider; And the heating anneal band sufficiently long that the arrangement mode that does not have the flame gap is formed and enough wide makes the tail pipe weld stress removing of being annealed preferably; And regulate flame temperature through the flame size of certain heating anneal band of by-pass valve control control according to request for utilization, make the annealing effect better.
As preferably, described heating anneal band is provided with a side and is connected with frame, the insulation cover body of its excess-three side opening.Adopt the present technique scheme, can effectively stop temperature and extraneous heat exchange action that flame produces, make heat obtain maximized focus utilization, improved the utilization ratio of heat, reduced waste.
As preferably, the burner of described heating anneal band is provided with asbestos gauge.Adopt the present technique scheme, asbestos gauge has effectively been suppressed waving of flame free state, makes flame more concentrated, and temperature is better constant, also saves the energy simultaneously.
Description of drawings
Fig. 1 is the structural representation of the thermal treatment unit of the utility model solar energy heat collection pipe.
Fig. 2 is the vertical view (the insulation cover body does not draw among the figure) of Fig. 1.
Fig. 3 is the left view of Fig. 1.
Shown in the figure: 1, burner, 2, by-pass valve control, 3, the heating anneal band, 4, the insulation cover body, 5, asbestos gauge.
Embodiment
For ease of explanation,, the thermal treatment unit of the solar energy heat collection pipe of utility model is elaborated below in conjunction with accompanying drawing.
Shown in Fig. 1 to Fig. 3; A kind of thermal treatment unit of solar energy heat collection pipe comprises burner 1 and by-pass valve control 2, and described burner 1 adopts a plurality of burners side by side and do not have an integral type heating anneal band 3 in flame gap; Described heating anneal band 3 is zonal structure; Described heating anneal band 3 is provided with a side and is connected with frame, the insulation cover body 4 of its excess-three side opening, and the burner 1 of described heating anneal band 3 is provided with asbestos gauge 5.
Embodiment: during use, opening controlling valve door 2, and light the burner 1 of heating anneal device; The gas range that operation is used like same family, simple and convenient, the outer tube of the solar energy heat collection pipe after the process welding afterwards is under the conveying of transporting mechanism; Carry out the thermal treatment that effective stress is removed through welding and the position that has stress through heating anneal band 3; Because flame is in extensive range, be heated evenly in the whole process, the stress removal effect is better.
In the above-described embodiments; Preferred forms to the utility model is described, obviously, and under the inventive concept of the utility model; Still can make a lot of variations; The change of the form of arranging like described burner 1, like the length of described heating anneal band 3 and the change of width dimensions, described for another example asbestos gauge 5 can adopt other material replacement with effect same etc.At this, should explain that any change of under the inventive concept of the utility model, being made all will fall in the protection domain of the utility model.
Claims (3)
1. the thermal treatment unit of a solar energy heat collection pipe; Comprise burner (1) and by-pass valve control (2); It is characterized in that: described burner (1) adopts a plurality of burners side by side and do not have the integral type heating anneal band (3) in flame gap, and described heating anneal band (3) is zonal structure.
2. ask the thermal treatment unit of 1 described solar energy heat collection pipe according to right, it is characterized in that: described heating anneal band (3) is provided with a side and is connected with frame, the insulation cover body (4) of its excess-three side opening.
