Abstract
The utility model relates to an armored large-power electric heater used for the heat preserving section of a float glass production line. The electric heater comprises a main body, a stainless steel square pipe, a connecting lead wire and a junction box; the main body comprises a spiral heating wire which goes through the stainless steel pipe; magnesia powder is filled between the heating wire and the stainless steel pipe; both ends of the heating wire are connected with metal lead wires led out from the stainless steel pipe and sealed by high temperature resistant insulating gel; both ends of the main body are arranged in parallel and connected with one end of the stainless steel square pipe, and the two metal lead wires parallelly go through the stainless steel square pipe and are connected with one end of the connecting lead wire in the stainless steel square pipe; the other end of the connecting lead wire is connected with the junction box on the other end of the stainless steel square pipe. The electric heater mainly solves the technical problems that the prior heater mainly adopts an exposed electric heating tape, the heating tape is very easy to be oxidized and damaged because of long-termed use at high temperature, and the safety of the equipment is reduced because the exposed heater which is electrified.
Description
Technical field:
The utility model relates to electric heater, particularly a kind of floatation glass production line soaking zone armouring large power, electrically heater.
Background technology:
Heater before domestic on the float glass process method glass production line mainly adopts the heat tape of bareing, and this heating tape is easy to oxidation in the medium-term and long-term use of high temperature and causes damage, and exposed heater causes the fail safe of equipment to descend under the state of energising.
The utility model content:
The purpose of this utility model is to provide a kind of floatation glass production line soaking zone armored electric heater, mainly solve the heat tape that existing heater mainly adopts bareing, this heating tape is easy to oxidation in the medium-term and long-term use of high temperature and causes damage, and exposed heater causes the technical problem of the fail safe decline of equipment under the state of energising.
For addressing the above problem, the utility model is achieved in that
A kind of floatation glass production line soaking zone armored electric heater is characterized in that: it is made of electric heater main body, stainless steel square tube, connection lead and terminal box; This electric heater main body comprises that helical form is arranged in the heating wire in the stainless steel tube, fills between this heating wire and the stainless steel tube and expires magnesia powder, and this heating wire two ends connection is drawn the outer metal lead wire of stainless steel tube and sealed with high-temperature insulation glue; After be arrangeding in parallel, the two ends of this electric heater main body are connected in stainless steel square tube one end, and two metal lead wires are parallel to be penetrated the stainless steel square tube and connects with lead one end that is connected in the stainless steel square tube, and connects the lead other end and is connected on the terminal box of the stainless steel square tube other end.
Described floatation glass production line soaking zone armored electric heater is characterized in that: weld with the stainless steel square tube after passing the stainless steel spacing block with perforation at the two ends of this electric heater main body.
Described floatation glass production line soaking zone armored electric heater is characterized in that: a plurality of insulation spacing blocks with perforation that be arranged in parallel in this stainless steel square tube, the aperture that two connection leads pass the insulation spacing block respectively is set in parallel.
Result of use of the present utility model is:
1, heater strip completely cuts off with extraneous air in the heat-generating pipe, and this can guarantee its fail safe and useful life.
2, heat-generating pipe adopts hermetically sealed welding with transition box, makes the corrosive gas in the workplace can not corrode lead-out wire, thereby heater is in a safe condition for a long time.

Embodiment:
See also Fig. 1-5, the structure of a kind of floatation glass production line soaking zone of the utility model armored electric heater is: it is made of electric heater main body 1, stainless steel square tube 2, connection lead 3 and terminal box 4; This electric heater main body 1 comprises that helical form is arranged in the heating wire 12 in the stainless steel tube 11, filling between this heating wire 12 and the stainless steel tube 11 expires magnesia powder 13, and these heating wire 12 two ends connect the metal lead wires 14 of drawing outside the stainless steel tube 11 and also seal with high-temperature insulation glue; After be arrangeding in parallel, the two ends of this electric heater main body 1 are connected in stainless steel square tube 2 one ends, and two metal lead wires 14 are parallel to be penetrated stainless steel square tube 2 and connects with lead 3 one ends that are connected in the stainless steel square tube 2, and connects lead 3 other ends and is connected on the terminal box 4 of stainless steel square tube 2 other ends.
Stainless steel spacing block 5 backs and 2 welding of stainless steel square tube with perforation are passed at the two ends of this electric heater main body 1.
The aperture that a plurality of insulation spacing blocks 6, two connection leads 3 with perforation that be arranged in parallel in this stainless steel square tube 2 pass insulation spacing block 6 respectively is set in parallel.
Add man-hour, electrical heating wire is the coiled spring-like in advance, two ends respectively add one section metal lead wire, the magnesium oxide insulating powder is prefabricated into the hollow shape, the heater strip of spring-like is penetrated in the magnesia powder of hollow shape, and the magnesia powder that will put on heater strip again penetrates in the stainless steel tube whole assembly is drawn into needed size through different wire drawing Mo.With pulling into the required ellipse of heating tube coiled of one, strip out metal lead wire, through hyperthermia drying, reach desired insulativity after, two ends are with the sealing of high-temperature insulation glue.The metal lead wire welding lead at two ends is to terminal box.Transition stainless steel square tube enters square tube in rotten connection lead to reach increase useful life with the hermetically sealed welding of stainless steel square tube to prevent decadent nature gas under working condition with heating tube with a slice corrosion resistant plate near the heating tube edge.To connect in the lead thereto.Three～four insulating supports are installed to guarantee that connecting lead can not contact the square tube inwall in the stainless steel square tube.
Therefore among this embodiment, the effect of magnesia powder has been an insulating effect, but magnesia powder very easily makes moist and must seal to guarantee the fail safe of heating tube with the strictness of high-temperature insulation glue through the heating tube of hyperthermia drying.Square tube must prevent that corrosive gas from entering square tube with heating tube and the square tube hermetically sealed welding of argon arc welding near the stainless section of jurisdiction of heating tube edge.
Being preferred embodiment of the present utility model only in sum, is not to be used for limiting practical range of the present utility model.Be that all equivalences of doing according to the content of the utility model claim change and modification, all should be technology category of the present utility model.
