Description
Technical Field
The utility model relates to a firing equipment technical field especially relates to a conical heater.
Background
In the medical field of blood analysis, since blood is prone to coagulation and to contamination from the external environment, many parameter indicators are often measured more accurately from gaseous blood, and therefore, it is necessary to subject the sample to high temperature vaporization by passing it through a heater before entering the analyzer. The sample inlet tube is generally conical in shape as a junction between the sample inlet tube and the detector to form a vaporization chamber.
The traditional heating mode is that set up a plurality of heating blocks on linking portion, and this kind of mode leads to heating temperature inhomogeneous, has local low temperature, leads to having the sample to remain on the inner wall, needs frequently to dismantle and wash linking portion, influences the use of instrument. In addition, the heater is directly arranged on the joint part, and strong acid and strong alkali can influence the heater during cleaning, thereby influencing the service life and the insulating property of the heater.
Therefore, a dedicated heater is required for use.
SUMMERY OF THE UTILITY MODEL
Based on above, the utility model aims at providing a conical heater treats the heating surface to special taper shape, realizes the even heating.
In order to achieve the purpose, the utility model adopts the following technical proposal:
the utility model provides a toper heater, sets up outside conical vaporization cavity, and it includes installation main part and heating plate, and the installation main part sets up to the conical cylinder form the same with the tapering of the vaporization cavity of treating the heating, and the expansion shape of heating plate is fan-shaped, and it is fixed in on the inner wall of installation main part after rolling into the tube-shape, has seted up the window on the installation main part, and the power cord of heating plate is worn out from the window, and the installation main part embolias from the awl pointed end of vaporization cavity, makes the heating plate laminate in the surface of vaporization cavity.
Particularly, the heating sheet is made of double-sided materials, one surface of the heating sheet is a Teflon layer, the other surface of the heating sheet is a silicon rubber layer, the silicon rubber layer is vulcanized and bonded on the mounting main body, and the Teflon layer is bonded with the vaporization cavity and is not adhered at high temperature.
In particular, the outer wall of the mounting body is provided with a fixing rim.
In particular, the end face of the mounting body is provided with positioning holes.
In particular, the end face of the mounting body is flush with the end face of the vaporization chamber.
To sum up, the beneficial effects of the utility model are that, compared with the prior art, conical heater is exclusively used in conical body of waiting to heat, makes its surface and heating member in close contact with to provide even, last high temperature heating condition, satisfy the heating needs, external contact heating effect is obvious in addition, fixed reliable, dismouting simple, be convenient for maintain, convenient to use.
Drawings
Fig. 1 is a schematic structural diagram of a conical heater provided by an embodiment of the present invention;
fig. 2 is a schematic diagram of a conical heater according to an embodiment of the present invention.
Detailed Description
The technical solution of the present invention is further explained by the following embodiments with reference to the accompanying drawings.
Referring to fig. 1 and 2, the present embodiment provides a conical heater, which is disposed outside a conical vaporization chamber 7, wherein the vaporization chamber 7 is connected to an analyzer, and the temperature of the vaporization chamber 7 can reach 200 ℃ for vaporization treatment before blood analysis according to the working environment.
The conical heater comprises a mounting main body 1 and a heating sheet 2, wherein the mounting main body 1 is arranged into a conical cylinder shape with the same taper as that of a vaporization cavity 7 to be heated, the heating sheet 2 is unfolded into a fan shape and is fixed on the inner wall of the mounting main body 1 after being rolled into a cylinder shape, particularly, the heating sheet 2 is made of a double-sided material, one side of the heating sheet is a silicone rubber layer, and the silicone rubber layer is vulcanized and bonded on the mounting main body 1 and is firmly combined and has good insulating property; the other surface is a Teflon layer which is attached to the vaporization cavity 7 and can ensure that the Teflon layer and the vaporization cavity are not adhered at high temperature.
The window 3 is arranged on the mounting main body 1, the power line 4 of the heating plate 2 penetrates out of the window 3, and the mounting main body 1 is sleeved in from the cone tip of the vaporization cavity 7, so that the heating plate 2 is attached to the outer surface of the vaporization cavity 7. Due to the large-area fit of the heating sheet 2, the vaporization cavity 7 is heated uniformly.
In addition, when in use, the end face of the installation body 1 is flush with the end face of the vaporization cavity 7, so that the normal connection of the vaporization cavity 7 and the analyzer is not influenced.
The end face of the installation body 1 is provided with a positioning hole 5, the outer wall of the installation body 1 is provided with a fixing edge 6, assembly of the installation body 1 and an analyzer or an external part is increased, and working stability of the heater is improved.
In conclusion, the conical heater is specially used for the conical to-be-heated body, the surface of the conical heater is in close contact with the heating body, so that an even and continuous high-temperature heating condition is provided, the heating requirement is met, and in addition, the external contact type heating effect is obvious, the conical heater is fixed and reliable, the conical heater is simple to assemble and disassemble, convenient to maintain and use.
The above embodiments have been merely illustrative of the basic principles and features of the present invention, and the present invention is not limited by the above embodiments, and does not depart from the spirit and scope of the present invention. The scope of the invention is defined by the appended claims and equivalents thereof.
