Abstract
The invention relates to a compressed air electric-heating pack, which is characterized by comprising a housing, and the housing is made of metal and is tube-shaped. Through holes are arranged on a housing wall adjacent to openings at two ends of the housing, an air-inlet pipe and an air-outlet pipe are respectively connected with the two through holes, and a thermal-insulation layer is also wrapped on the outer surface of the housing. Cover plates are arranged on the openings at two ends of the housing and are fixed on the housing or the thermal-insulation layer through screws. Electric-heating tubes arranged along the axial direction of the housing are arranged in the housing, and two ends of the electric-heating tubes are fixed on the cover plates at two ends of the housing and are connected with power supply equipment through wires. By adopting the electric-heating pack, compressed air can be heated in advance, the time of drying through air-blowing can be reduced, the operation efficiency is improved, and the waste of compressed air resource is reduced.
Description
Technical field
The present invention relates to a kind of heat packs, is to carry out electrically heated heat packs to compressed air specifically, and it can be used for liquid removal, drying with the surface of the work in the manufacture field.
Background technology
In industrial circle, compressed air is to use the most a kind of industrial gasses, be particularly useful for casting, manufacture field, its main application is to remove dust or the liquid of the position that ground, operation post or workpiece etc. are difficult to clear up, and can play dry effect.And in the prior art, compressed-air actuated use only is that air gun directly is connected with compressed air piping, controls compressed air by the switch of air gun object is blown, thereby remove dust, the liquid on object surface, makes its rapid draing.But when winter or indoor temperature were lower, although still compressed air can play liquid and the dry effect of removing, but because object, liquid and compressed-air actuated temperature are all lower, blow dried often needed time of growing.Like this, not only wasted a large amount of compressed air resources, and operating efficiency is lower.
Summary of the invention
The problem to be solved in the present invention provides a kind of compressed air electrical heating bag, adopts this heat packs to the compressed air heating of going ahead of the rest, and can reduce the time of blow dried, improves operating efficiency, reduces the waste of compressed air resource.
For addressing the above problem, take following scheme:
The characteristics of compressed air electrical heating bag of the present invention are to comprise housing, and this housing is made of metal and is tubulose.Described housing is all having through hole near on the shell wall at both ends open place, and the two through hole place is connected with respectively air inlet pipe, escape pipe, and the outer surface of housing also is coated with heat-insulation layer.The opening part at described housing two ends all has cover plate, and cover plate is fixed by screws on housing or the heat-insulation layer.Described enclosure interior has along the axial arranged electric heating tube of housing, and the two ends of electric heating tube are fixed on the cover plate at housing two ends, and the two ends of electric heating tube all are connected with power supply unit by wire.
The further improvement of the present invention scheme is that the quantity of described electric heating tube is no less than 3, and they circumferentially are evenly arranged along enclosure interior, and gapped between electric heating tube and inner walls.Like this, can guarantee that this heat packs is comparatively even to the heating of Compressed Gas.
In the such scheme, on the cover plate at described housing two ends, in position corresponding to electric heating tube pore is arranged, all there is external screw thread at the two ends of electric heating tube, stretch out in the cover plate pore corresponding with it respectively at the two ends of electric heating tube, and cover has nut on the external screw thread, thereby electric heating tube is fixed on the cover plate at housing two ends.
Take such scheme, have the following advantages:
Because on the housing of compressed air electrical heating bag of the present invention air inlet pipe and escape pipe are arranged, and electric heating tube is arranged in the housing, the two ends of electric heating tube all are connected with power supply unit by wire.During use, only need this compressed air electrical heating bag is connected between compressed air piping and the air gun; When air gun is in closed condition, will be full of compressed air in the housing, at this moment, open the power supply unit power supply, electric heating tube is heated up the compressed air in the housing is heated; Then, control compressed air to the object blow dried by the switch of air gun again.Like this, the compressed air temperature that blows out in the air gun is higher, even in the situation that winter or indoor temperature are lower, it is dry that compressed air also can carry out fast decontamination to object, thereby reduced the time of blow dried, improved the efficient of operation, reduced the waste of compressed air resource.
Description of drawings
Fig. 1 is the structural representation of compressed air electrical heating bag of the present invention;
Fig. 2 is that enlarged drawing is looked on the left side of Fig. 1.
The specific embodiment
As depicted in figs. 1 and 2, compressed air electrical heating bag of the present invention comprises housing 1, and this housing 1 is made of metal and is tubulose.Described housing 1 is all having through hole near on the shell wall at both ends open place, and the two through hole place is connected with respectively air inlet pipe 4, escape pipe 6, and the outer surface of housing 1 also is coated with heat-insulation layer 5.The opening part at described housing 1 two ends all has cover plate 2, and cover plate 2 is fixed by screws on housing 1 or the heat-insulation layer 5.Described housing 1 inside has along the axial arranged electric heating tube 3 of housing 1, the quantity of electric heating tube 3 is no less than 3, the quantity of electric heating tube 3 is 6 in the present embodiment, they are evenly arranged along housing 1 internal circumferential, and gapped between electric heating tube 3 and housing 1 inwall, can guarantee like this compressed air of the housing 1 of flowing through is carried out full and uniform heating.In the position of electric heating tube 3 correspondences pore is arranged on the cover plate 2 at described housing 1 two ends, all there is external screw thread at the two ends of electric heating tube 3, stretch out in the cover plate corresponding with it 2 pores respectively at the two ends of electric heating tube 3, and cover has nut on the external screw thread, thereby electric heating tube 3 is fixed on the cover plate 2 at housing 1 two ends.The two ends of described electric heating tube 3 all are connected with power supply unit by wire.
During use, only need this compressed air electrical heating bag is connected between compressed air piping and the air gun.When air gun is in closed condition, housing 1 is interior will to be full of compressed air, at this moment, open the power supply unit power supply, make electric heating tube 3 heat temperature raisings, and compressed air and electric heating tube 3 in the housing 1 carry out heat exchange, make the compressed air temperature rising.Then, the compressed air that is heated by the switch control of air gun is again blown to object, can reach quick-drying effect.
