Description

A kind of electrothermal tube that is used for side heat soy bean milk making machine cup

Affiliated technical field

The utility model relates to a kind of electrothermal tube and manufacturing approach thereof of side heat soy bean milk making machine cup.

Background technology

Electrothermal tube partly is made up of metal outer pipe, heating wire, magnesia powder, eduction rod and sealing etc. usually; The existing electrothermal tube that is used for the heating of soy bean milk making machine cup adopts immersion stainless steel electrothermal tube usually; Like disclosed a kind of title on March 3 " machine for making soya-bean milk easy to clean " publication number in 2010 was the patent of CN201414385Y; The structure of the machine for making soya-bean milk easy to clean that this patented technology scheme proposes is made up of parts such as head, cup, electrothermal tube, motors, and head lower cover is provided with electrothermal tube, and electrothermal tube stretches in the cup; And in cup, a flow-disturbing muscle is being set; The electric heating body does not have the two ends of heating wire to flatten to be shaped to the spoiler with flow-disturbing function, and its weak point is: immersion type heating element Yin Gaowen heater is directly contacted easy scale formation and because of the high nutrition that destroys soya-bean milk of contact site temperature with soya-bean milk; Bottom combined type aluminium electrothermal tube; As on March 3rd, 2010 disclosed a kind of name to be called " a kind of soy bean milk making machine " publication number be the patent of CN20141382Y; The structure of a kind of soy bean milk making machine that this patented technology scheme proposes is made up of parts such as cup, heat-conducting plate, heat-generating pipe, grooves; Described bottom of cup is equipped with heat-conducting plate, the corresponding heat-generating pipe of heat-conducting plate position is provided with groove, and after heat-generating pipe energising heating, the heat delivered of heat-generating pipe is to heat-conducting plate; Be transferred to bottom of cup through groove again; This heat-generating pipe bottom has added groove in order to disperse each regional temperature of bottom of cup, but can't avoid the easy layering and precipitating of a kind of molecule slurry, causes the bottom to be prone to fouling and is difficult for cleaning and sticks with paste problem such as the end easily.

The utility model content

The utility model is according to the weak point of above-mentioned prior art; A kind of electrothermal tube that is used for side heat soy bean milk making machine cup is proposed; Provide its manufacturing approach simultaneously, not only fine proposition solves the difficult cleaning of soy bean milk making machine and sticks with paste end problem, and avoids soy bean milk making machine fouling and cost waste effectively.

The technical scheme that the utility model adopts is: adopt the aluminum metal electrothermal tube of little caliber, comprise that mainly the dielectric magnesia powder 3 of heating wire 4, eduction rod 1 and heat conduction that aluminum metal outer tube 2 and pipe are interior is formed, electrothermal tube forms the laminated type structure of bilayer or multilayer through dish corner bevelling pipe; Adopt the mode of extrusion molding to reach compact special cross-section structure then; Cross sectional shape approaches rectangle, width L=7.5mm, height H=6.1mm; Pipe is arranged at Width; Form the bigger conical surface or the face of cylinder in the inboard,, improve the performance of heat-transfer effect and electrothermal tube to be suitable for composite welding.

The manufacturing approach of the electrothermal tube of above-mentioned side heat soy bean milk making machine cup is following:

The first step is fixed on heating wire 4 and eduction rod 1 usefulness magnesia powder 3 with special-purpose powder feeding machine and processes the electrothermal tube straight tube in the metal outer pipe 2.

Second goes on foot, and straight tube is formed the ring shape electrothermal tube of compactness through the mode of oil pressure, bend pipe and extruding.

In the 3rd step, electrothermal tube is made the inboard formation conical surface or the face of cylinder 5 through extruding, and in extrusion process, make two mouths of pipe outwards stick up the protection of line up when being convenient to composite welding.

The mould structure of extruding is shown in Figure 4: the cylinder (oil cylinder) through both sides compresses electrothermal tube (dish circle back) earlier; Matched moulds then; Patrix B face promotes counterdie A face and makes counterdie movable holddown C face and counterdie D face extruding electrothermal tube; The electrothermal tube of patrix G face and counterdie F face extruding simultaneously makes the stressed extruding in electrothermal tube four sides realize compact special cross-section structure, and pin receives the extruding of E point that the mouth of pipe is tilted upward on the process of extruding in addition; And pin receives the extruding of right movable holddown that pin is outwards stuck up through the H hole down, and the requirement that finally reaches technological design guarantees the performance of electrothermal tube again.

The utility model has the advantages that: the laminated type structure of electrothermal tube employing dish corner bevelling pipe multilayer, be welded in the side of soy bean milk making machine cup, can solve up hill and dale and stick with paste the end, difficultly clean, be prone to a series of problems such as fouling.The utility model, compact conformation and simple can be realized minimization of cost, prevents the loss of soya-bean milk nutrition effectively, and guarantees fail safe and the practicality used.

Among the figure, 1-eduction rod, 2-metal shell, 3-dielectric, 4-heating wire, the 5-conical surface or the face of cylinder;

Embodiment

Shown in Fig. 1-3; A kind of electrothermal tube that is used for side weldering soy bean milk making machine cup of the utility model includes metal shell 2 and is filled in the eduction rod 1 in the shell, the dielectric 3 (like magnesia) of heat conduction, forms the conical surface or the face of cylinder 5 that is suitable for welding through crooked, fashion of extrusion then.

Its manufacturing approach is following:

The first step, the dielectric 3 of the heat conduction that heating wire 4 and eduction rod 1 usefulness is closely knit is fixed in the metal shell 2;

Second goes on foot, and electrothermal tube is formed the heating circle of compactness through the mode of oil pressure, bend pipe;

In the 3rd step, electrothermal tube is made the inboard formation conical surface or the face of cylinder 5 (needs that are suitable for the side welding) through extruding, and in extrusion process, make two mouths of pipe outwards stick up the protection of line up when being convenient to composite welding.

Though below design and instance according to the utility model purpose have been done to elaborate with reference to accompanying drawing; But those of ordinary skills can recognize; Under the precondition that does not break away from the claim limited range; Still can make various improvement and conversion to the utility model, and this improvement and conversion still should belong to the protection range of the utility model.
