Description

Novel ash melting property determinator

The utility model relates to the mensuration field of material physical property, is mainly used in the mensuration of one of ature of coal physical index.

The coal ash melting property of one of China's coal analysis index is measured at present, mainly adopts carborunbum tube high temperature furnace, controllable silicon controller and platinum rhodium--the analyzer that-platinum thermocouple etc. constituted.Along with science and technology development, also released the electrode slice that connects high temperature furnace by the power outlet on the single-chip microcomputer in recent years on the market, the extension line of the platinum rhodium in the high temperature furnace--platinum thermocouple connects single-chip microcomputer and carries out temperature control, singlechip controller UNICOM computing machine; Be provided with the camera head of band optical filter before the high temperature furnace viewport, camera head UNICOM computing machine, the picture and text that make sample awl vary with temperature situation in high temperature furnace show on computer screen, and can store, and watches for accessing at any time.Video camera, single-chip microcomputer, the application of computing machine on the ash fusibility high temperature furnace have realized automatic control, make this technical products that obvious improvement arranged, and have alleviated labor intensity of operating personnel greatly, have improved condition of work, have improved the accuracy of test.But in use also found its weak point: the center of Yin Gaowen fire door is provided with viewport, is provided with camera head before the viewport, makes blow-on door dress, very inconvenient when getting tested sample; Body of heater skin temperature height is not noted the staff that easily burns slightly, and working environment is dangerous; Control section adopts single-chip microcomputer to connect microcomputer, has increased cost, and single-chip microcomputer is subjected to the restriction of technical characterictic own, and the temperature-raising characteristic error of furnace temperature is big.

The purpose of this utility model is that improvement takes on furnaceman and makes condition, reduces the high temperature furnace skin temperature, reduces and controls cost automatically.

The technical scheme that realizes the utility model purpose is: by high temperature furnace; on the basis of the ash melting property determinator that camera head and automatic control section are formed; novel ash melting property determinator is characterised in that the anti-high temperature protection cover of installing on the high temperature furnace shell; the high temperature furnace runing rest is housed under the high temperature furnace; rotary-tray is housed on the support; the high temperature furnace of the anti-high temperature protection cover of band is sat and is contained on the rotary-tray; before the viewport that is contained in high temperature furnace of the camera lens correspondence of camera head; mainly contain power outlet on the controller that device such as controllable silicon forms and connect electrode slice on the high temperature furnace; automatically set up temperature acquisition in the microcomputer of control; control card; thermopair temperature acquisition in compensating wire is connected to microcomputer in control line on the controller and the high temperature furnace; on the control card interface; image pick-up card in the video signal cable of camera head and the microcomputer connects; microcomputer is communicated with printer, forms the utility model.

Concrete structure of the present utility model is provided by the following examples and accompanying drawing thereof.

Fig. 1 is the structural representation of the novel ash melting property determinator that the utility model proposes.

Fig. 2 is the structural representation of Fig. 1 high temperature furnace rotating part.

Below in conjunction with CONSTRUCTED SPECIFICATION and the working condition of accompanying drawing detailed description according to the concrete instrument that the utility model proposes.

With reference to Fig. 1, Fig. 2; the horizontal-type high temperature stove (1) that constitutes by the carborunbum tube heating element; anti-high temperature protection cover (5) is housed on the shell of high temperature furnace (1); anti-high temperature protection cover (5) is made by steel plate; the anti-scattered thermal-protective coating of aluminium silicate wool is housed on the inner wall surface thereof; anti-high temperature protection cover (5) has certain spacing with the high temperature furnace shell, and is shaped on the heat radiation blind window on the afterbody cover that is positioned at high temperature furnace (1).Under the high temperature furnace (1) of the anti-high temperature protection cover (5) of band runing rest (17) is housed; rotary-tray (8) is housed on the runing rest (17); connecting bolt (16) is associated in the high temperature furnace (1) of rotary-tray (8) with the anti-high temperature protection cover (5) of band; the viewport that is contained in high temperature furnace (1) (12) of the camera lens correspondence of CCD camera head (6) is preceding; the main electrode slice (7) on power outlet (11) the connection high temperature furnace (1) on the controller of forming by parts such as controllable silicons (2); automatically set up temperature acquisition in the microcomputer (3) of control; control card; the temperature acquisition of thermopair (9) in compensating wire (10) is connected to microcomputer (3) in control line (15) on the controller (2) and the high temperature furnace (1); on the control card interface; image pick-up card in the video signal cable (13) of CCD camera head (6) and the microcomputer (3) connects, microcomputer (3) and printer (4) UNICOM.

This instrument is when using, should earlier high temperature furnace (1) be revolved and turn 90 degrees, even the viewport (12) of high temperature furnace (1) becomes 90 degree with the camera lens of camera head (6), the detected sample of packing into then awl, after installing the fire door that shuts high temperature furnace (1), make high temperature furnace (1) go back to 90 degree again, make the camera lens of viewport (12) the aligning camera head (6) of high temperature furnace (1), with microcomputer (3) and the logical power supply of going up of controller (2), open microcomputer (3) and promptly enter ash fusibility mensuration program, begin the ＂ key with mouse-click ＂, microcomputer (3) is just monitored carborunbum tube high temperature furnace (1) temperature rise speed automatically, as survey coal ash, the high temperature furnace temperature rise is a per minute 15-20 degree before 900 degree, per minute temperature rise 5 degree when 900-1500 spends, when furnace temperature rises to 900 when spending, open camera system (6), Sample Image changing condition and corresponding temperature value are deposited automatically, and on computer screen display image and heating curve, ash awl sample reaches flow temperature or furnace temperature and rises to 1500 degree and promptly finish test procedure of coal ash, microcomputer (3) stops test automatically, and provides test result.Rotate high temperature furnace (1) 90 degree then, open fire door, take out sample.
