Description

A kind of car-bottom furnace trolley sealing heat insulating protecting apparatus
Technical field
The utility model relates to a kind of car-bottom furnace trolleys to seal heat insulating protecting apparatus, belong to metallurgy industry vehicle bottom formula Heating furnace trolley seals heat insulation device technical field.
Background technique
Referring to attached drawing 1, currently, existing heating furnace trolley sealing thermal insulation protection is all using the double sand seals of furnace wall heat-resisting cast iron The sealing insulating protection structure of the double sand sealing grooves of knife, trolley heat-resisting cast iron, mainly includes sand seal knife assembly, sand seal, sand sealing groove, trolley A sand seal knife assembly, the sand sealing knife in sand seal knife assembly is respectively welded in track, trolley and trolley wheel, the two sides below trolley For cast iron quality, sand seal knife assembly plays back-fire relief, sealing function, sand sealing groove is arranged in accumulation of heat ditch lower part, by sand seal knife assembly Lower end is located in sand sealing groove, and back-up sand forms sand seal in sand sealing slot.The frequent problem of this sealing insulating protection structure It is:Gap accumulation of the heating furnace furnace wall sand sealing knife component because of self weight, high temperature or iron scale between furnace wall and sand seal knife assembly Extruding cause furnace wall sand seal knife assembly sink, deformation, displacement, trolley be driven out to drive into be obstructed cause to scratch, damage, seal failure, Causing trolley to be stuck in furnace cannot pass in and out, and have side sand seal knife assembly whole at high operating temperatures or portion because cutting to pieces with trolley when serious It rubs situation about being pushed out outside furnace to occur, especially furnace uses as a servant the later period, and because seal protection is failed, trolley frame and running gear are by thermal damage Be unable to run, frequently in repair, stove production efficiency is greatly affected, and maintenance, maintenance workload and expense increase, and production capacity cannot discharge Also resulting in process, the production cost increases, this is the problem of domestic pharmaceutical industry industry can all encounter, and needs to improve.
Utility model content
The utility model aim is to provide a kind of car-bottom furnace trolley sealing heat insulating protecting apparatus, can be avoided furnace wall Sand seal knife assembly sinks, deformation, shifts, and improves the sealing effect of trolley two sides and furnace wall, solves to ask present in background technique Topic.
The technical solution of the utility model is:
A kind of car-bottom furnace trolley sealing heat insulating protecting apparatus, includes sand seal knife assembly, sand seal, sand sealing groove, trolley A sand seal knife assembly is fixed in track, trolley and trolley wheel, the two sides below trolley respectively, and the lower end of sand seal knife assembly is located at In sand sealing groove, sand is inserted in sand sealing groove and forms sand seal, sand seal knife assembly is equipped with high aluminum fiber, is equipped with air in sand seal Pipe, the air hose are equipped with multiple air ports, and the outside of sand sealing groove, which is built, sand sealing groove barricade.
The lower end of the sand seal knife assembly is inserted into sand seal.
The sand seal knife assembly is inserted into the part in sand seal as wedge shape.
High aluminum fiber on the sand seal knife assembly is fixed on sand seal knife assembly by anchoring piece.
Multiple air ports on the air hose are upward flat-shaped spout.
The sand sealing groove barricade built on the outside of the sand sealing groove is close to bogie wheels.
The utility model has the beneficial effects that:
(1)Heat insulation can be improved in high aluminum fiber on sand seal knife assembly, so that trolley is dropped weight 10t or more, and drop Deformation, damage caused by low trolley side and whole heated heating, extend bogie wheels, steel construction service life, improve shove charge Amount;
(2)Increase air hose in sand seal and multiple air ports be set, by spraying air, prevent flame or flue gas into Enter the gap between trolley and furnace wall, protects trolley side surface upper part frame and lower part sand seal knife assembly;Pallet bottom can be substantially reduced Temperature improves trolley vehicle frame, bogie wheels and top cast iron frame operating ambient temperature, prolongs the service life;
(3)The sand sealing groove barricade of masonry can protect heat radiation, the baking that bogie wheels are not likely to occur by flue gas or flame It is roasting;
(4)Eliminate makes trolley be stuck in the hidden danger in furnace because of sand sealing knife component strain or displacement, improves stove operation Reliability;
(5)It is easy to maintain, sand sealing groove internal oxidition iron need to be only cleared up during blowing out and fills sand and replacement damage in right amount High-alumina refractory fiber, maintenance, it is easy to maintain, dimension inspection cost reduce;
(6)It can reduce the gap of trolley two sides and furnace wall, improve sealing effect.
Detailed description of the invention
Fig. 1 is background technique structural schematic diagram;
Fig. 2 is the utility model structure diagram;
In figure:Sand seal knife assembly 1, sand seal 2, high aluminum fiber 3, sand sealing groove 4, sand sealing groove barricade 5, air hose 6, trolley track 7, anchoring piece 8, trolley 9, trolley frame 10, accumulation of heat ditch 11, furnace wall 12, trolley wheel 13.
Specific embodiment
Below in conjunction with attached drawing, by example, the utility model is described in further detail.
Referring to attached drawing 2, a kind of car-bottom furnace trolley seals heat insulating protecting apparatus, comprising sand seal knife assembly 1, sand seal 2, A sand seal knife assembly 1, sand are fixed in sand sealing groove 4, trolley track 7, trolley 9 and trolley wheel 13, the two sides below trolley 9 respectively The lower end of sealing knife component 1 is located in sand sealing groove 4, and sand is inserted in sand sealing groove 4 and forms sand seal 2, sand seal knife assembly 1 is equipped with height Aluminum fiber 3 is equipped with air hose 6 in sand seal 2, and the air hose 6 is equipped with multiple air ports, and the outside of sand sealing groove 4, which is built, to be had Sand sealing groove barricade 5.
