Abstract
The invention provides a novel heating tube for a solar cell sintering furnace. The novel heating tube is stable in heating and meanwhile can be mounted firmly. The novel heating tube comprises a hollow quartz glass tube, heating wires are distributed in the quartz glass tube in the length direction of the quartz glass tube, the heating wires are of a spiral winding structure, and the surface layers of the heating wires are coated with high temperature resistant heat insulation layers. Threaded sleeves are fixedly arranged at the two ends of the quartz glass tube in a sleeved mode, external threads are arranged on the threaded sleeves, and the external threads are meshed with internal threads of a heating tube mounting hole reserved in a hearth wall. Check blocks used for limiting positions are arranged on the two sides of the threaded sleeves, and ceramic heat insulation ends are arranged on the two sides of the check blocks. The two ends of each heating wire penetrate out of the quartz glass tube, the check blocks and the ceramic heat insulation ends at the same time, and connecting terminals are arranged at the ends of the heating wires. Further more, the check blocks are arranged on the threaded sleeves in a meshed and screwed mode.
Description
Technical field
The present invention relates to the production equipment of solar battery sheet, be specifically applied to the sintering of solar battery sheet.
Background technology
Along with popularizing of solar cell power generation, the demand of solar battery sheet increases, also increasing as visual plant-solar battery sheet sintering furnace demand and the use amount of producing solar battery sheet, solar battery sheet sintering furnace often will be realized failure-free operation in several months, therefore the power consumption of sintering furnace is quite large, is mainly reflected in heating tube in the heating of warm area.
Current sintering furnace heating tube comes with some shortcomings in the time of heating, concrete, because heating tube temperature in the time heating can reach more than 1000 ℃, therefore, needs resistant to elevated temperatures design, guarantees the stability of heating tube; Meanwhile, sintering furnace uses for a long time, need to be by firm heating tube being arranged on burner hearth.
Summary of the invention
The present invention is directed to above-mentioned the deficiencies in the prior art, a kind of heating tube for solar battery sheet sintering furnace that the thermally-stabilised while again can firm installation that adds is provided.
The technical solution adopted for the present invention to solve the technical problems is: a kind of novel heating pipe of solar battery sheet sintering furnace, comprise the quartz glass tube of hollow, along the length direction of quartz glass tube, be furnished with heater strip therein, heater strip is spiral winding structure, and heater strip top layer applies high temperature resistant heat insulation layer;
Above-mentioned quartz glass tube two ends fixing suit thread bush, thread bush is offered external screw thread, and this external screw thread engages with the internal thread of heating tube installing hole reserved on hearth wall; Thread bush both sides are provided for spacing block, and block both sides are ceramic thermal insulation end;
Above-mentioned heater strip two ends pass quartz glass tube simultaneously, block and ceramic thermal insulation section, and its end arranges binding post.
Further: above-mentioned block engagement screws and is arranged on thread bush.
Further: above-mentioned heater strip is Fe-Cr-Al alloy or Ni-Cr alloy.
The invention has the beneficial effects as follows:
The novel heating pipe of solar battery sheet sintering furnace of the present invention, by will apply high-temperature-resistant layer on heater strip, heater strip whole installation, in quartz glass tube inside, can be realized good radiation heating effect simultaneously by good resistance to elevated temperatures simultaneously, adds thermally-stabilised; On heating tube, be provided with the thread bush of installing on burner hearth for heating tube is threaded connection, make the firm stable installation of heating tube energy after installing.

Accompanying drawing is the schematic cross-section of heating tube.
Description of reference numerals:
1-heater strip, 2-quartz glass tube, 3-thread bush, 4-block, 5-ceramic thermal insulation end, 6-binding post.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described:
As shown in drawings, it shows one embodiment of the present of invention, the novel heating pipe of solar battery sheet sintering furnace of the present invention, comprise the quartz glass tube 2 of hollow, along the length direction of quartz glass tube 2, be furnished with heater strip 1 therein, heater strip 1 is spiral winding structure, and heater strip top layer applies high temperature resistant heat insulation layer;
Above-mentioned quartz glass tube 2 two ends fixing suit thread bush 3, thread bush 3 is offered external screw thread, and this external screw thread engages with the internal thread of heating tube installing hole reserved on hearth wall; Thread bush 3 both sides are provided for spacing block 4, and block 4 both sides are ceramic thermal insulation end 5;
Above-mentioned heater strip two ends pass quartz glass tube 2 simultaneously, block 4 and ceramic thermal insulation section 5, and its end arranges binding post 6.
Above-mentioned block 4 engagements screw and are arranged on thread bush 3.
Above-mentioned heater strip is Fe-Cr-Al alloy or Ni-Cr alloy.
Above-mentioned heating tube, in the time being used for the sintering burner hearth of sintering furnace, is short-wave infrared heating tube; When for baking furnace, it is medium-wave infrared heating tube.
By reference to the accompanying drawings the preferred embodiment for the present invention is explained in detail above, but the invention is not restricted to above-mentioned embodiment, in the ken possessing those of ordinary skills, can also under the prerequisite that does not depart from aim of the present invention, make a variety of changes.
Do not depart from the spirit and scope of the present invention and can make many other changes and remodeling.Should be appreciated that and the invention is not restricted to specific embodiment, scope of the present invention is defined by the following claims.
