Abstract
The utility model discloses a CODcr (chemical oxygen demand) digestion tube which comprises a cylindrical tube body, an electrical heating wire and a temperature sensor, wherein the two ends of the cylindrical tube body are closed, the electrical heating wire is wound around the outer wall of the tube body, and the temperature sensor extends to the inner cavity of the tube body. The two ends of the tube body are respectively provided with a raised heating wire fixed pillar, the outer wall of the tube body is provided with a raised heating wire limited pillar, the lower end of the tube body is provided with a sensor installing tube, the sensor installing tube extends to the inside of the cavity, one end of the sensor installing tube is opened, and the other end of the sensor installing tube is closed. When the CODcr digestion tube is used, the tube body is heated by using the heating wire, so that the tube body is heated uniformly; and the temperature sensor in the tube body monitors the temperature at any time, so that an effect of precisely controlling the temperature is achieved, therefore, the tube can be applied to an automatic analysis instrument. In addition, the CODcr digestion tube disclosed by the utility model has the advantages of small volume, simple structure, capability of preventing polluted gas from volatilizing, and the like.
Description
Technical field
The utility model relates to a kind of water analysis and uses digestion tube, particularly relates to a kind of digestion tube of CODcr automatic analytical instrument.
Background technology
At present, the CODcr digestion system mainly contains half-sealed digestion system and all-sealed digestion system.Does not shut fully half-sealed digestion system upper end, adopts 0.6-0.7MPa as thresholding pressure, prescribes a time limit when pressure is higher than, and valve open is prescribed a time limit when pressure is lower than down, valve closing, and this method can reduce the probability that makes the digestion pool blast because of pressure is excessive.But uncovered system has corrosive gas and evaporates, contaminated environment, etching apparatus, the health that threatens operating personnel.And the digestion tube volume of these two kinds of systems is big, all must be from pipe end heating, and temperature that can't accuracy-control system.Also there is such shortcoming in disclosed in the patent 200520100477.3 " CODcr on-line monitoring appearance digestion utensil ", and also possibly there are complex structure in these vessel, shortcoming such as it is inhomogeneous to be heated.
Summary of the invention
Deficiencies such as existing C ODcr digestion tube volume is big in order to overcome, complex structure, heating are inhomogeneous, the utility model provide a kind of simple in structure, be heated evenly, automatic analytical instrument can accurately be controlled, can be applied to temperature CODcr digestion tube.
The utility model solves the technical scheme that its technical matters adopted: a kind of CODcr digestion tube; Comprise cylindrical tube; It is characterized in that: the two ends of said body are enclosed construction, are wound with electrical heating wire on the outer wall of said body, and the inner chamber of said body is provided with sensor.
Be equipped with the heater strip fixed leg of protrusion on the outer wall at said body two ends.
All misplace on the outer wall of said body both sides and be provided with several heater strip limited posts.
The outer wall of said body bottom is provided with the cylindrical mounting pipe of an end opening one end sealing, and described sensor is located in the mounting pipe.
The beneficial effect of the utility model is: the digestion tube volume is little, and is simple in structure; Heater strip is wrapped on the tube wall, and body is heated evenly; At any time monitor heating-up temperature through a sensor that inserts in the body, thereby realize accurately control temperature, thereby can be applied to automatic analytical instrument; Airtight HTHP is cleared up, and temperature, constant pressure, has accelerated reaction process, has overcome the corrosive gas volatilization of uncovered system to the pollution of environment with to corrosion on Equipment.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
Embodiment:
Below in conjunction with accompanying drawing the utility model is further specified.
As shown in Figure 1, the CODcr digestion tube of the utility model, its body 1 is cylindrical, the body two ends are provided with closed opening 2,3.The outer wall on body top is provided with the heater strip fixed leg 4 of protrusion, and the outer wall of body bottom is provided with the heater strip fixed leg 5 of protrusion.Evenly be provided with many heater strip limited posts 6 that are arranged in a linear on the tube wall between the two heater strip fixed legs 4 and 5, heater strip limited post 6 is dislocatedly distributed in the body both sides, along limited post 6 electrical heating wire 9 is wrapped on the body.The embedded cylinder shape sensor mounting pipe 7 in body bottom.Sensor mounting pipe 7 one end openings, end sealing, its blind end tilts to insert in the inner chamber 8 of CODcr digestion tube.Filling heat-conductive silica gel in the mounting pipe 7 is put into temperature sensor 10.In normal operation; The both ends open sealing; Participate in bottom opening 3 injections of all ingredients of reaction by digestion tube, after reagent added completion, the reagent in the inner chamber 8 of 9 pairs of digestion tubes of controller (not shown) control electrical heating wire heated; Temperature sensor 10 can fast detecting to the temperature variation of clearing up liquid in pipe, guaranteed accuracy control over temperature.
Above embodiment is merely the utility model a kind of embodiment wherein, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to the protection domain of the utility model.Therefore, the protection domain of the utility model patent should be as the criterion with accompanying claims.
