Abstract
The invention discloses a quick-to-heat test tube which comprises a test tube body. A sealing plug is arranged at the top end of the test tube body, an exhaust tube is arranged on the sealing plug, a right-angle bend is arranged in the middle of the exhaust tube, the test tube body comprises a cylindrical glass tube, an arc-shaped bottom end is arranged on the lower portion of the glass tube, and radian of the arc-shaped bottom end is 2.14; a metal wrapping piece covers the outer end face of the arc-shaped bottom end, and metal heating pieces are arranged on the outer surface of the glass tube spirally. The quick-to-heat test tube has the advantages that the defects of the prior art can be overcome, and the quick-to-heat test tube is reasonable and novel in structural design.
Description
Technical field
The present invention relates to one and quickly heat test tube, belong to teaching equipment field.
Background technology
Test tube, the instrument that chemical laboratory is conventional, serve as the reaction vessel of a small amount of reagent, when room temperature or heating, (should preheat before heating, not so test tube easily bursts.) use.Test tube divides common test tube, tool test tube, centrifuge tube etc. multiple.In teaching demonstration is tested, it is generally to use alcohol burner heating.Alcohol burner is single-point type heating, can only heat the bottom of test tube, so make heat time heating time long, affect demonstration time and teaching process.
Summary of the invention
The deficiency existed for prior art, the technical problem to be solved is to provide one and quickly heats test tube, and easy to use, firing rate is fast.
For solving above-mentioned technical problem, the present invention adopts the technical scheme that, one quickly heats test tube, and including test tube body, the top of test tube body is provided with a sealing plug, and sealing plug is provided with an exhaustor, is provided with a right-angle bending in the middle part of exhaustor；Described test tube body includes a cylindrical glass tubing, and glass tubing bottom is arc bottom, and the radian of arc bottom is 2.14；Being coated with metal wrap sheet on the outer face of described arc bottom, the outer surface of glass tubing is provided with METAL HEATING PROCESS sheet, METAL HEATING PROCESS sheet is that cylindrical helical is arranged on the outer surface of glass tubing；Pitch is glass tubing length the 1/4 of described METAL HEATING PROCESS sheet, the helical angle of METAL HEATING PROCESS sheet 28.5 degree；The thickness of METAL HEATING PROCESS sheet is the 1/2 of the pipe thickness of glass tubing.
Optimize, above-mentioned quick heating test tube, 1.5 times of the pipe thickness that thickness is glass tubing of described arc bottom.
It is an advantage of the current invention that it can overcome the drawback of prior art, reasonable in design is novel.In order to accelerate firing rate, the design of the application covers on the outer face of arc bottom metal wrap sheet, improves the infiltration rate of heat, accelerate the infiltration rate of heat.Invisible spectro liquid typically can irrigate more, so the design of the application arranges the METAL HEATING PROCESS sheet of arrangement in cylindrical helical on the outer surface of glass tubing, METAL HEATING PROCESS sheet and metal wrap sheet connect, so heat on metal wrap sheet is delivered to middle part and the top of glass tubing through METAL HEATING PROCESS sheet, further increases firing rate.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention；
In figure: 1 be sealing plug, 2 be exhaustor, 3 be glass tubing, 4 be arc bottom, 5 be metal wrap sheet, 6 for METAL HEATING PROCESS sheet.
Detailed description of the invention
The technical characterstic of the present invention is expanded on further below in conjunction with the accompanying drawings with specific embodiment.
The present invention is that one quickly heats test tube, and including test tube body, the top of test tube body is provided with a sealing plug, and sealing plug is provided with an exhaustor, is provided with a right-angle bending in the middle part of exhaustor；Described test tube body includes a cylindrical glass tubing, and glass tubing bottom is arc bottom, and the radian of arc bottom is 2.14；Being coated with metal wrap sheet on the outer face of described arc bottom, the outer surface of glass tubing is provided with METAL HEATING PROCESS sheet, METAL HEATING PROCESS sheet is that cylindrical helical is arranged on the outer surface of glass tubing；Pitch is glass tubing length the 1/4 of described METAL HEATING PROCESS sheet, the helical angle of METAL HEATING PROCESS sheet 28.5 degree；The thickness of METAL HEATING PROCESS sheet is the 1/2 of the pipe thickness of glass tubing.1.5 times of the pipe thickness that thickness is glass tubing of described arc bottom.
It is an advantage of the current invention that it can overcome the drawback of prior art, reasonable in design is novel.In order to accelerate firing rate, the design of the application covers on the outer face of arc bottom metal wrap sheet, improves the infiltration rate of heat, accelerate the infiltration rate of heat.Invisible spectro liquid typically can irrigate more, so the design of the application arranges the METAL HEATING PROCESS sheet of arrangement in cylindrical helical on the outer surface of glass tubing, METAL HEATING PROCESS sheet and metal wrap sheet connect, so heat on metal wrap sheet is delivered to middle part and the top of glass tubing through METAL HEATING PROCESS sheet, further increases firing rate.
Certainly, described above is not limitation of the present invention, and the present invention is also not limited to the example above, those skilled in the art, in the essential scope of the present invention, the change made, retrofits, adds or replaces, all should belong to protection scope of the present invention.
Claims (2)
