Description
Technical field
The utility model relates to a kind of dry heat drafting case that is used for chemical fibre industry, relates in particular to a kind of electric heater unit that is used on the dry heat drafting case.
Background technology
The dry heat drafting case is to be used for fiber is carried out a kind of equipment of drafting forming in the chemical fibre industry, and the dry heat drafting case is provided with electric heater unit.Electric heater unit mainly is to be made of some electric heating tubes, and the terminals of electric heating tube are arranged on the housing of casing, and the remainder of this electric heating tube is positioned at casing.Remainder is positioned at its inside because the terminals of electric heating tube are arranged on the housing of casing, electric heating tube is in cantilever position, electric heating tube is sagging because of the part that the heating distortion is located in the casing more when work, this causes the damage of electric heating tube easily, thereby has shortened the service life of heater greatly.
The utility model content
The technical problems to be solved in the utility model provides a kind of long service life, the care and maintenance electric heater unit of dry heat drafting case easily.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: the electric heater unit of dry heat drafting case, comprise: the U-shaped electric heating tube, terminals, incubation chamber, support bar and support orifice plate, incubation chamber is provided with front end face and rear end face, one end of support bar is arranged on the rear end face, support the other end that orifice plate is fixed on support bar, on front end face and rear end face, be respectively arranged with through hole, terminals are located in the through hole of front end face and rear end face, the remainder of U-shaped electric heating tube is installed in the through hole that supports orifice plate, in incubation chamber, be filled with insulation material, on the surface of U-shaped electric heating tube, evenly be provided with spiral fin.
The utility model has the advantages that: prolong the service life of electric heating tube greatly, installs, care and maintenance is all very convenient.
Description of drawings
Fig. 1 is the structural representation of the electric heater unit of the utility model dry heat drafting case.
Fig. 2 is the left view of Fig. 1.
Fig. 3 is the right view of Fig. 1.
Among the figure: 1, U-shaped electric heating tube, 2, terminals, 3, incubation chamber, 4, support bar, 5, support orifice plate, 6, front end face, 7, rear end face, 8, spiral fin.
The specific embodiment
Fig. 1, among Fig. 2 and Fig. 3, the electric heater unit of dry heat drafting case, comprise: U-shaped electric heating tube 1, terminals 2, incubation chamber 3, support bar 4 and support orifice plate 5, incubation chamber 3 is provided with front end face 6 and rear end face 7, one end of support bar 4 is arranged on the rear end face 7, support the other end that orifice plate 5 is fixed on support bar 4, on front end face 6 and rear end face 7, be respectively arranged with through hole, terminals 2 are located in the through hole of front end face 6 and rear end face 7, the remainder of U-shaped electric heating tube 1 is installed in the through hole that supports orifice plate 5, in incubation chamber 3, be filled with insulation material,, on the surface of U-shaped electric heating tube 1, evenly be provided with spiral fin 8 in order to increase radiating effect.
Because the terminals 2 of the utility model U-shaped electric heating tube 1 are installed on the incubation chamber 3, remainder is installed in the through hole that supports orifice plate 5, therefore U-shaped electric heating tube 1 is under the supporting role of incubation chamber 3 and support orifice plate 4, overcome that prior art U-shaped electric heating tube 1 is in cantilever position and the deficiency that makes the sagging easy damage of part in its casing, so prolonged greatly the service life of U-shaped electric heating tube 1.While is structure because U-shaped electric heating tube 1 and incubation chamber 3 and support orifice plate 4 are connected as a whole, and is when use or care and maintenance, all very convenient.
