Technical field:

The utility model relates to the instrument that a kind of cement quality detects, and is specifically related to the sampler in the cement chloride ion content detects.

Background technology:

Chlorion is a kind of objectionable constituent in the cement, and surpassing certain content can produce corrosion to steel bars in concrete.The existing GB JC/T420 of the chemical analysis of chlorion has carried out standard to its method in the cement raw material, wherein requires with hydrogen oxide and acid decomposed by phosphoric acid cement sample, and the separated chlorion is collected specimen and measured with titrimetry.The separation of chloride ion in cement in the past is several instruments and a glassware with manually piecing together with collecting, and adds an electric furnace and heats up, and with the clock and watch timing heating-up time, and then becomes liquid to collect the volatile matter distillation condensation of gas of coming out.And, need to use two little Drexel bottles and connecting pipe in operation, because of the many connectors of Drexel bottle are many, use inconvenient easily gas leakage, and the chemical constitution in the gas is lost easily; And the gas after the evaporation owing to add aspiration pump with original big bottle, is put in the big bottle with triangular flask by condenser pipe again, carries out coldly really connect hell to pay, and effect being bad, and is difficult for the chloride liquid of recovery, thereby cause test findings inaccurate.In a word, the mode personal error of this handwork is big, timing uncertainty, and it is many and scattered to piece together the glass test tube of use, and the separation that causes chlorion causes measurement result inaccurate with to collect precision not enough, can not satisfy the requirement of new standard JC/T420.

The utility model content:

The utility model purpose is to be to design a kind of compact conformation, to connect closely and chlorion analyser that can robotization control, this can be used for together the cement chloride ion content detect in chlorion separate and sample collection.

To achieve these goals, the utility model has adopted following technical scheme: chlorion analyser of the present utility model includes: an air pump connects a spinner-type flowmeter; One Drexel bottle, draft tube are connected to the outlet side of spinner-type flowmeter; One stay-warm case, thorax bottom has an electric furnace, electric furnace upper support to be provided with a quartzy distillation cascade in it, and the escape pipe of Drexel bottle is communicated with the draft tube of quartzy distillation cascade; One serpentine condenser, the escape pipe of quartzy distillation cascade is linked the import of serpentine condenser; And a conical flask, be connected in the liquid outlet of serpentine condenser.

Above-mentioned chlorion analyser also is provided with ECU (Electrical Control Unit), comprising: a power switch, and the control electric furnace is opened; One air pump and timer switch, the unlatching of a control air pump and a timer; One temperature controller receives the signal of being located at the temperature sensor in the thorax in the stay-warm case, adjusts the temperature of electric furnace in the stay-warm case; And an alarm, be installed between air pump and the spinner-type flowmeter, be electrically connected timer.

Above-mentioned chlorion analyser also comprises a cabinet, cabinet inside installing ECU (Electrical Control Unit), air pump, Drexel bottle and stay-warm case, and a jig is established in the cabinet outside, and serpentine condenser hang on the jig.

The above chlorion analyser between the draft tube of the escape pipe of Drexel bottle and quartzy distillation cascade, is provided with pipe jointer between the escape pipe of quartzy distillation cascade and the import of serpentine condenser.This pipe jointer is provided with: first pipeline, its openend are made as horn-like and surperficial frosted; One conical plug, its conical surface frosted and with the first pipeline tapping end socket, its stub end stretches out a tail pipe; And second pipeline, be socketed on the tail pipe of conical plug.

Above-mentioned chlorion analyser, Drexel bottle is provided with bottle stopper.

Adopt above technical scheme, the handwork sampling that the utility model is more traditional has reduced Drexel bottle quantity, only adopts single Drexel bottle, has reduced the chemical constitution in the gas and has easily lost, and has increased accuracy of experimental results; The utility model has designed special-purpose connector into and out of tracheae, makes things convenient for the loading and unloading between Drexel bottle, serpentine condenser and the connecting tube; Increase elements such as temperature control, timing control, air-flow control, realized robotization control, increased the accuracy that detects; This practical new-type simple structure compactness, reasonable in design durable, the accuracy of detection height.
