Abstract

A heating wire tubular furnace mainly comprises a tubular hearth, an outer heat preservation body, a metal outer shell and a furnace door. The tubular hearth is formed by splicing two half cylindrical hearth bodies with the thick walls. Axial slots are formed in the circumferential face of the wall of a middle inner hole formed by the spliced two half hearth bodies, and heating wires are arranged in the slots; the splice faces of the two half hearth bodies are matched steps in the radial direction, middle splice faces are two half planes, and the two ends of each middle splice face are an inward contraction face and an outward convex face respectively; the heating wires on the wall of the middle inner hole of the two half hearth bodies are connected in series and then are led out to be connected with an external power source. The heating wire tubular furnace has the advantages of being reasonable and compact in structure, convenient to install and use, and capable of lowering use cost, and prolonging the service life of the hearth.

Description

A kind of heating wire tubular type stove

Technical field

The utility model relates to a kind of mini type high temperature heating wire tubular type stove that the occasions such as laboratory are used that is mainly used in, belong to experimental facilities technical field.

Background technology

In school or scientific research institutions, mostly need a kind of high temperature experimental facilities, the key technology of these high temperature experimental facilities is the structure composition of burner hearth.In prior art, applying more is a kind of high-temperature box type burner hearth being made into integration, in this integral type burner hearth, there is pair burner hearth cavity to carry out direct-fired heater and dispose fire door that can folding etc., heater is arranged separately on the inner chamber wall of burner hearth, fire door arranges separately and is arranged on burner hearth; Owing to being that monoblock type is made, the comparatively inconvenience that therefore seems in the process that heater is installed, maintains also inconvenience, once somewhere heater damage etc. will cause the damage of whole burner hearth, reduces its service life, thereby increases experimental cost.

Summary of the invention

The purpose of this utility model is to overcome the deficiency that prior art exists, and provides a kind of rational in infrastructure, compact, easy to install, can reduce use cost, extends the burner hearth heating wire tubular type stove in service life.

The purpose of this utility model completes by following technical solution, described heating wire tubular type stove, it mainly comprises tubular type burner hearth, outer thermal insulator, metal shell and fire door, described tubular type burner hearth is spliced by two halves thick cyclinder shape hearth body, on the middle inner hole wall forming after two halves hearth body splicing, along being provided with axial slots on periphery, and heating wire is installed in slotted eye.

The Mosaic face of described two halves hearth body is radially respectively match step-like, and middle Mosaic face is two half-planes, the two ends of middle Mosaic face respectively each other one section inside contract face and one section of outer convex surface; Heating wire in the middle of described two halves hearth body on inner hole wall picks out respectively and is connected in external power after connecting separately.

Described two halves hearth body passes through after binding agent heat bonding at Mosaic face, separately there is an outer thermal insulator that formed by insulation material, that be definite shape at the outside of tubular type burner hearth compoiste adhering, and being wrapped with metal shell in thermal insulator, the fire door of tubular type hearth body is closed in configuration.

The utlity model has rational in infrastructure, compactly, easy to install, can reduce use cost, extend the features such as burner hearth service life.

Brief description of the drawings

Fig. 1 is tubular type hearth body end face structure schematic diagram described in the utility model.

Fig. 2 is A face and B face combination decomposition texture schematic diagram in Fig. 1.

Detailed description of the invention

Below in conjunction with accompanying drawing, the utility model is described in detail: shown in Fig. 1,2, heating wire tubular type stove described in the utility model, it mainly comprises tubular type burner hearth 1, outer thermal insulator, metal shell and fire door (not shown), described tubular type burner hearth 1 is spliced by two halves thick cyclinder shape hearth body 11, on middle endoporus 2 walls that form after two halves hearth body 11 splicing, along being provided with axial slots 3 on periphery, and heating wire 4 is installed in slotted eye 3.

Shown in figure, the Mosaic face of described two halves hearth body 11 is radially respectively match step-like, and middle Mosaic face is two half-planes 12, the two ends of middle Mosaic face 12 respectively each other one section inside contract face 13 and one section of outer convex surface 14; Heating wire 4 in the middle of described two halves hearth body 11 on inner hole wall picks out respectively and is connected in external power after connecting separately; Because described resistance wire mounting groove 3 is open-type slots, resistance wire is positioned at groove or part exposes outside groove, and what its was applicable to thicker stove silk inlays installation, and the heating of stove silk is directly dissipated in furnace chamber, the temperature in can Fast Heating furnace chamber.

Two halves hearth body 11 described in the utility model passes through after binding agent heat bonding at Mosaic face, separately there is an outer thermal insulator 5 that formed by insulation material, that be definite shape at the outside of tubular type burner hearth compoiste adhering, and being wrapped with metal shell 6 in thermal insulator 5, the fire door of tubular type hearth body is closed in configuration.

Two halves hearth body 11 described in the utility model is to be respectively mixed into refractory mixture with refractory material and fiber, then forms with mould molding.Described heating wire external power supply, and can realize the control of temperature by heating controlling organization, due to these contents that is prior art, the utility model, as long as understand the technology contents of this area, can be implemented easily in this area.
