Description
The utility model relates to a kind of calorimeter device, specifically be a kind of automatic barrel section of automatic calorimeter of the calorific value of measuring solid or liquid combustible, be mainly used in industry or departments such as coal, oil, petrochemical industry, electric power, papermaking, cement, agriculture and animal husbandry, medicine, scientific research, teaching.
Traditional calorimeter comprises temperature-constant bucket, thermometer and manual controller, and temperature-constant bucket comprises outer bucket, interior bucket, electric mixer, oxygen bomb, spark electrode etc., and controller is used for temperature-constant bucket control stirring, send electric ignition.Test process comprises: prepare oxygen bomb, the bucket water yield and water temperature in regulating, interior bucket is moved into temperature-constant bucket and puts into oxygen bomb, open then and stir, regularly reading, energising igniting behind the official hour, allow sample fully burn, interior bucket water temperature rises, thermometer test water temperature, record the temperature value that reads after waiting to burn fully, the formula with regulation carries out as a result conversion again.The interior bucket of this calorimeter is unfixed, can put forward, and interior bucket claims the water yield and water temperature to regulate needs manually-operated, waste time and energy, and the degree of accuracy of this operation is experience and the technical merit that relies on operating personnel to a great extent, often causes personal error, influences measuring accuracy.Though the present domestic traditional personal control of microcomputer control unit replacement that begun to adopt, the weighing of interior bucket water and water temperature are regulated and still need manually be finished, and human error still fails to eliminate as the main source of measure error.Because the microcomputerized control technology is very advanced, so this solution of together inscribing at first is improvement and the renewal of temperature-constant bucket.
The purpose of this utility model be for automatic calorimeter bucket water is provided in a kind of manual weighing of need not and regulate its water temperature, to improve the automatic bucket of measuring accuracy and testing efficiency, rely on manually-operated temperature-constant bucket thereby replace.
The technical solution of the utility model is as follows: it is connected with realizing the microcomputer control unit that control and data are processed, comprise casing, case lid, outer barrel, interior bucket, control circuit board and temperature probe, interior bucket fixed in position is in outer barrel, a constant volume device that is used for holding and measuring interior bucket water also is installed in the outer barrel, this constant volume device by inlet channel and intake pump with outer barrel UNICOM, by water pipeline and conveying pump and interior barrel of UNICOM; Be provided with discharge outlet in the interior bucket, this discharge outlet is by drainage pipeline and draining pump and outer barrel UNICOM.Each water pump all links to each other with control circuit board.Microcomputer control unit control whole test process, it both can be the single card microcomputer control circuit board, also can be the computer system that comprises printer and other control interface.The one-piece construction that the utility model is then integrated.
In the utility model, be equipped with for stirring water to regulate the water pump that stirs of water temperature balance the bottom in outer barrel, keeps the water temperature equilibrium in the whole outer barrel.Case lid is connected on the casing by flip-open cover mechanism, and the case lid bottom is equipped with ignitor, interior bucket temperature probe, stirring motor and paddle.The control circuit board that links to each other with microcomputer control unit is connected respectively and stirs water pump, spark electrode, stirring motor and temperature probe, carries out processes such as water stirring, temperature adjustment, igniting, thermometric and data processing by the unified control of micro computer.Outer barrel and inner barr all can adopt nonmetallic materials to make, and has broken traditional material mode of using.
Employing of the present utility model makes the calorimetric test process become full-automatic process, is specifically described as follows:
(1) energized, calorimeter enters test mode, and operating personnel earlier put into oxygen bomb with the fuel sample that weighs up, and install ignition wire, with the oxygen bomb oxygen of substituting the bad for the good, put into bucket;
(2) instruction of bucket water in microcomputer control unit is assigned and extracted, the draining pump of bottom of the barrel are all discharged the water in the interior bucket by drainage pipeline and are entered outer barrel;
(3) control module is assigned and is added the water instruction, and elder generation fills with constant volume device by inlet channel with the water in the outer bucket by intake pump, guarantees that like this test water is equivalent at every turn, and the volume of constant volume device is fixed, can determine that with volume water is heavy, therefore need not artificial water gaging; Afterwards, again the water in the constant volume device all is injected in the interior bucket;
(4) a barrel stirrer begins to stir (until end of test (EOT)) in, and inner bucket water temperature equilibrium in keeping is by the temperature probe measurement inside and outside bucket water temperature of interior bucket and outer bucket and by computer record;
(5) after interior bucket water temperature was basicly stable, control module indication point ignition circuit control ignition electrode was connected, ignition wire conductive exothermal in the oxygen bomb, sample combustion;
(6) sample combustion heats up the oxygen bomb body, and is transmitted in the interior bucket water, and water temperature is raise, and temperature probe timing acquiring water temperature delta data is transported to micro computer;
(7) after sample combustion is complete, interior bucket water temperature stops to rise;
(8) microcomputer control unit carries out interpretation of result and calculating, and send printer to carry out report printing output relevant test data, and the draining pump of controlling simultaneously bottom of the barrel is extracted the water of interior bucket out and is discharged in the outer barrel, and test finishes.
In sum, the utility model has been realized the full-automation of calorimetric process, only oxygen bomb need be installed during test, without the water transfer temperature, carries out suitable data with computer and processes the accuracy that can guarantee test result; Also heavy without weighing water, interior bucket need not put forward, bucket institute water consumption is sent into interior bucket by water pump in the time of will testing with built-in constant volume device at every turn, testing efficiency height, speed are fast, greatly alleviated laboratory personnel's working strength, eliminate human error, thereby improved measuring accuracy, can replace the manually-operated temperature-constant bucket of traditional need.
