The heating device for glass steel anchor rod forming has the characteristics of simple structure, high heating efficiency, and safety.
Description
Technical field
It relates to a kind of heater the present invention, particularly relates to the heater that a kind of glass fibre reinforced plastics rockbolts moulding is used.
Background technology
Anchor pole is the element of colliery tunnel support, mainly there are two large defects in the anchor pole that conventional steel material is made, be that skill is corroded and lost efficacy and produced spark because coal-cutting machinery cuts anchor pole or anchor pole and the collision of other equipment, cause local gas blast and dust spontaneous combustion, there is potential safety hazard, therefore be eliminated gradually.Glass fibre reinforced plastics rockbolts has the plurality of advantages such as light weight, corrosion resistant, fire-retardant, antistatic, high strength, and glass fibre reinforced plastics rockbolts is widely used by each large colliery at present.In addition glass fibre reinforced plastics rockbolts is also widely used in subway tunnel, engineering bank protection, highway, bridge supporting, the fields such as municipal works.
Glass fibre reinforced plastics rockbolts is made up of under the effect of curing agent many wire long fibres and resin.Its moulding is in hauling machine directed traction, separately carries out screw thread with a flexible wire and is wrapped in heating cure and forms.Thread forming in glass fibre reinforced plastics rockbolts process and curing efficiency are determining the working (machining) efficiency of whole production line.The one start screw that current process equipment uses individual wire circulation to be wound around in the time of thread forming, in production process in the case of the rotating speed of hauling speed and Wiring apparatus coordinate bad steel wire very easily pull apart, cause and shut down or produce waste product.Speed of wrap is too fast or cross and can affect slowly thread pitch and change, impact and the cooperation of nut.
Also the heater that solidifies use after having people to glass fibre reinforced plastics rockbolts moulding improves, to enhancing productivity, as Chinese patent ZL201020188456.2 discloses the heater that a kind of glass fiber reinforced plastic anchor rod molding machine is used, heat and establish heat-insulation layer between cartridge heater and outer cover by cartridge heater, improving heating effect.But because the heating system of current glass fibre reinforced plastics rockbolts equipment is electrical heating (far infrared), there is self unvanquishable defect:
1, before production, preheating time is long, at least 40 minutes;
2, because existing equipment is to put far-infrared heating tube in baking oven, and more than large (more than the needed electric power 40KW of the whole production line) cost-per-meter 1 of electric thermal power spends electricity;
3, thermal loss is large, and due to the problem of baking oven heat insulation effect, the heat that electrical heating discharges is not absorbed completely by anchor pole, so the thermal efficiency is low, about 70% left and right;
4,, in the time suddenly having a power failure or mechanical disorder need to be shut down, the anchor pole in baking oven can, because oven temperature can not be lowered the temperature rapidly, and burnt, and causes waste.
So only improve the efficiency that is heating and curing after fiberglass moulding and there is limitation by improving electric heater unit structure.
Summary of the invention
For above problem, the invention provides the heater that a kind of glass fibre reinforced plastics rockbolts moulding is used, that this device has is simple in structure, the thermal efficiency is high, use safe feature.
Technical scheme of the present invention is, the heater that a kind of glass fibre reinforced plastics rockbolts moulding is used, this heater comprises microwave transmission system, micro-wave screening case, gel resin system, electric-control system, and microwave transmission system is made up of multiple microwave emitters, and the microwave that microwave emitter is launched is just to goods; Gel resin system runs through the operation capable of circulation of micro-wave screening case.For example gel resin system is made up of scrap belt and scrap belt carrying roller, and scrap belt is placed on scrap belt carrying roller, is provided with scrap belt carrying roller inside and outside micro-wave screening case, and scrap belt carrying roller drives scrap belt that the glue dropping on scrap belt is transported to outside micro-wave screening case.
The casing of described micro-wave screening case is individual layer stainless steel, which is provided with cover plate.
Described scrap belt is Teflon tap.
Described electric-control system is controlled with PLC, can preset the multiple method of operation.
The invention has the beneficial effects as follows, the heating system that glass fibre reinforced plastics rockbolts moulding is used adopts heating using microwave to solidify, the penetrability of microwave is good, warming and cooling rate is fast, easy-to-use, in the process of heating, can make goods heat from outside to inside simultaneously, thereby cause resin solidification rapidly, according to on-the-spot test, the anchor pole of diameter 18mm, after microwave hyperthermia, the curing molding speed of goods can reach 5-6 m/min.And traditional infrared heating, heat conduction is outside in, the thermal conductivity factor of resin is very low, absorb external heat and reach solidification temperature length consuming time, curing rate is very slow, thereby affects the shaping speed of goods, and the anchor pole curing molding speed of diameter 18mm is 1.2 meters-1.5 ms/min.The stainless micro-wave screening case of individual layer simultaneously; this case is processed without insulation, there is no connector lug and any electro-heat equipment in casing, in the time suddenly having a power failure or mechanical disorder need to be shut down; in shielded box, cooling rate is fast, and anchor pole goods can not burnt not in time because of cooling.That the heater that this glass fibre reinforced plastics rockbolts moulding is used has is simple in structure, the thermal efficiency is high, use safe feature.
Brief description of the drawings
Fig. 1 is structural representation of the present invention, is also the schematic diagram of a kind of embodiment;
Fig. 2 is profile of the present invention.
Detailed description of the invention
Below in conjunction with drawings and the specific embodiments, the present invention is further detailed explanation.
As depicted in figs. 1 and 2, the heating system that glass fibre reinforced plastics rockbolts moulding of the present invention is used, comprise microwave transmission system, micro-wave screening case, gel resin system, electric-control system, wherein, microwave transmission system is made up of multiple microwave emitters 7, and microwave emitter is arranged in microwave bay 8, and the microwave that microwave emitter 7 is launched is just to anchor pole goods 1, in micro-wave screening case 5, be provided with goods support roller 2, goods support roller 2 is arranged on the two side of micro-wave screening case 5; Described gel resin system comprises scrap belt 3 and scrap belt carrying roller 4, in shielded box, scrap belt carrying roller 4 is positioned at goods support roller 2 belows, described scrap belt carrying roller 4 is arranged on the two side of micro-wave screening case, scrap belt 3 is placed on scrap belt carrying roller 4, scrap belt carrying roller 4 outside shielded box is arranged on support 6, and scrap belt carrying roller 4 is to its supporting role of scrap belt.When use, anchor pole goods 1 are placed on goods support roller 2, absorb the microwave of microwave emitter transmitting and solidify, transmit scrap belt 3 and run through micro-wave screening case 5, drive motors drives and transmits scrap belt 3 circular flows, when goods are solidified, drop down the resin flowing down and take in time outside shielded box, prevent the overheated burning of resin, keep clean in shielded box.
