Abstract
The utility model provides a kind of Novel electric heating plate, electric boiling plate is made up of two pieces of flat boards, two pieces of flat boards have screw to be connected and fixed, two pieces of dull and stereotyped surfaces are all distributed with groove, channel section is semicircle, a groove on one flat plate and a groove on another one flat plate form circular hole, at circular hole built with electric heating tube.Advantage of the present utility model: be convenient to mount and dismount electrothermal tube; When heat transfer area is large, power is higher, this electric boiling plate has good temperature homogeneity; Not by the restriction of electrothermal tube diameter, length; The useful life of electrothermal tube can be significantly improved.
Description
Technical field
The utility model is one widely used electric heating element in the industrial production, a kind of Novel electric heating plate specifically.
Background technology
Electric boiling plate is a kind of electrical heating elements very ripe on market, and its resistance wire is sealed in hollow pipe and air exclusion, and the precision of installing the deep hole of electric heating tube is the principal element determining its useful life.When adopting normal drill bit drilling processing electric heating tube installing hole, drilling depth is less, if hole in opposite directions in two, holes axiality cannot be ensured again, therefore for deep hole, lengthening drill bit drilling must be adopted, when drill bit is longer, during drilling, drill bit head more easily offsets, and the geometry in the hole got out more cannot ensure, thus causes electrothermal tube to install drawback not in place.In the case, electrothermal tube be enable to be in place, or be pressed into by electrothermal tube by external force by force, or expanding aperture could freely load electrothermal tube, for the former, electrothermal tube is once damage whole electric hot plate and namely scrap; For the latter, the excesssive gap between electrothermal tube and hole wall and affect heat trnasfer, causes electrothermal tube local overheating and burns out electrothermal tube too early, the useful life of electrothermal tube is had a greatly reduced quality.One piece of traditional formula electric boiling plate also exist electrothermal tube use after overheating deforming cannot take out, gun drilling time drill bit the drawback such as easily to fracture.
Electrothermal tube in use its damage mainly contains following several situation: internal resistance silk blows, head resistance Threaded Connector Coupling place oxidation scission, pipe internal resistance wire contact with tube wall and cause ground short circuit, the oxidation of pipe internal resistance wire etc.Regardless of which kind of situation, it is replaceable that electrothermal tube damage must take out rear.
Summary of the invention
For solving the problem, the utility model provides a kind of Novel electric heating plate, electric boiling plate is made up of two pieces of flat boards, two pieces of flat boards have screw to be connected and fixed, two pieces of dull and stereotyped surfaces are all distributed with groove, channel section is semicircle, and a groove on one flat plate and a groove on another one flat plate form circular hole, at circular hole built with electric heating tube.
Described circular hole is arranged in parallel, and described circular hole is blind hole or through hole.
Two pieces of flat boards of described electric boiling plate can be Q235 material.
Advantage of the present utility model: be convenient to mount and dismount electrothermal tube; When heat transfer area is large, power is higher, this electric boiling plate has good temperature homogeneity; Not by the restriction of electrothermal tube diameter, length; The useful life of electrothermal tube can be significantly improved.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, the utility model is made up of two pieces of flat boards, two pieces of flat boards have screw 1 to be connected and fixed, two pieces of dull and stereotyped surfaces are all distributed with groove, channel section is semicircle, a groove on one flat plate and a groove on another one flat plate form circular hole 2, at circular hole 2 built with electric heating tube.
Described circular hole is arranged in parallel, and described circular hole is blind hole or through hole.
The number of described circular hole is one or more.
The utility model mainly solves electrothermal tube and damages the problem that cannot take out, and when electrothermal tube damages, only need unclamp the screw fixing two pieces of electric boiling plates, just can easily take out replacing electrothermal tube.And tradition one piece of formula electric boiling plate, hand-made factor of making limits, and electrothermal tube, once damage and cannot take out, causes the phenomenon that whole electric boiling plate is scrapped.Novel electric heating plate due to machining accuracy high, the gap of electrothermal tube and circular hole is little, significantly can improve heat transfer, extends useful life of electrothermal tube.
The utility model is very practical, has certain promotional value, produces normally all have positive effect to improving the quality of products, ensureing.
