Abstract
The utility model relates to a coal quality quick analyzer, which is used for detecting the index content of the samples of coals such as moisture content, volatile component, fixed carbon, ash content, etc. so as to determine the quality of the coals. The heating furnace of the utility model at least comprises two furnace bodies which are up and down combined in series. The furnace with high temperature is positioned on the upper part, the furnace with low temperature is positioned on the lower part, and the furnace tubes are communicated. Furnace temperature is controlled by a microcomputer, the heating furnace and a sample entering tray are connected with an elevating mechanism and can elevate, and the sample entering tray can rotate through a rotating mechanism, realizing sample entering continuous. The elevation of the furnace bodies of the utility model makes the samples of the coals directly enter into of the furnace body with corresponding temperature, making the temperature of the samples instantaneously arrive at test temperature, having no waiting time, and achieving the aim of fast speed and high efficiency.
Description
The utility model relates to a kind of ature of coal quick analytic instrument, is the instrument that utilizes thermogravimetric analysis principle check Coal Quality.
The content of moisture, volatile component, fixed carbon and ash content is the leading indicator of check Coal Quality in the coal, the method test of adopting heating to weigh usually.Traditional thermogravimetric analyzer comprises heating furnace and balance, heating furnace only contains a body of heater, has only a burner hearth in the stove, tested coal sample is in the same burner hearth from start to finish, by heating up or cooling in the external circuit control stove, weigh by balance and to record the weight numerical value that coal sample loses in the relevant temperature section, the weight percentage of calculating each component according to this.Because the variation right and wrong between each section of coal analysis temperature are successional, adjacent two probe temperature spans are big, so heating furnace is from a greenhouse cooling or be warmed up to another temperature and need long stand-by period, impact analysis speed, inefficiency.
The purpose of this utility model provides a kind of ature of coal quick analytic instrument, according to temperature in the needed stove of test event, make coal sample directly enter another humidity province from a humidity province, shorten the waiting time of heating up, lowering the temperature, accelerate analysis speed, increase work efficiency.
The utility model ature of coal quick analytic instrument comprises heating furnace, day gentle sample introduction dish, and the sample introduction dish has sample holes, and heating furnace includes two bodies of heater of tandem compound up and down at least, high temperature furnace is last, low temperature oven is following, and boiler tube communicates, and heating furnace and sample introduction dish link to each other and liftable with an elevating mechanism.Temperature is passed through system controlled by computer in the stove of each body of heater.The screw rod that said elevating mechanism contains the motor-driven rotation reaches the lifting nut of threaded engagement with it, and this nut drives heating furnace and the lifting of sample introduction dish by crossbeam.This elevating mechanism also can adopt intermeshed gear rack structure or other can realize being provided with between the lower furnace body on the physical construction heating furnace of lifting the division board that reduces the heat radiation influence.Several sample holes are arranged on the sample introduction dish, and each hole is by circumferential arrangement, and sample introduction dish and one are rotatable by the motor-driven sample introduction gearing mesh of sample introduction, thereby makes respectively to enter the bar hole and arrive the fire door sample introduction successively.
The utility model ature of coal quick analytic instrument is owing to adopted the furnace binding of high temperature furnace and low temperature oven tandem compound, mode by the body of heater lifting makes coal sample be introduced into low temperature oven, testing moisture content under low furnace temperature, immediately enter in the high temperature furnace, can directly carry out the project testing under the high temperature, do not ask when having the waiting of gradient of temperature therebetween, accelerated test speed.This analysis instrument can make the coal sample on the dish arrive the fire door follow-on test successively by sample introduction disc spins mechanism, reaches continuous, quick, the efficient purpose of testing of coal bar.
Below in conjunction with description of drawings example structure of the present utility model.
Fig. 1 is the example structure figure of this Rapid analysis of coal quality instrument.
During Fig. 2 (1)-2 (3) expression coal samples detect, the change in location process of heating furnace.
Fig. 3 is the structural representation of rack-and-pinion elevating mechanism.
As shown in Figure 1, heating furnace is formed by high temperature furnace 8 and low temperature oven 9 tandem compounds, is provided with division board 16 on it between the lower furnace body, and boiler tube 19 connects goes up the lower hearth (see figure 2), and furnace roof is provided with bell 15; Balance 14 is provided with the arm beam of steelyard 13 straight up, sample introduction dish 12 and 11 engagements of sample introduction gear, the sample introduction dish is rotatable under sample introduction motor 10 drives, and the crucible 18 that coal sample is housed places the sample holes top of sample introduction dish, the sample introduction dish can have a plurality of sample holes, and each hole is by circumferential arrangement.Elevating mechanism comprises motor 6, driving pulley 5, driven pulley 4, screw rod 3, lifting nut 7, slide bar 2, sliding sleeve 1, crossbeam 17 links to each other with lifting nut 7, heating furnace is fixed on the right-hand member of crossbeam, and the left end of crossbeam connects sliding sleeve 1, and sample introduction motor 10 is contained on the crossbeam.Nut 7 and screw rod 3 are with threaded engagement, and during the screw rod rotation, nut 7 promptly produces elevating movement.The sense of rotation of screw rod is by motor 6 controls, and the lifting of nut changes according to the change of screw rod sense of rotation, thereby the crossbeam that links to each other with nut 17 drive bodies of heater 8,9 and sliding sleeve 1 are along slide bar 2 slip liftings.
When Fig. 2 (1)-(3) represent that this ature of coal quick analytic instrument is in each test phase, the change in location of heating furnace.Fig. 2 (1) is an initial state, and heating furnace is in a high position, and high temperature furnace 8 and low temperature oven 9 reach temperature required by system controlled by computer respectively, and the crucible 18 that coal sample is housed has been weighed by balance.Starter motor 6, elevating mechanism promptly drives body of heater 8,9 and sample introduction dish 17 drops to Fig. 2 (2) position, crucible 18 arrives the top of scale stalks 13 and enters in the low temperature oven 9 at this moment, temperature is 105-170 ℃ in the stove of low temperature oven, in stove, feed nitrogen, keep appropriate time, moisture in coal is evaporated, weigh by balance, calculate the percent water content in this coal sample.Make heating furnace continue to descend arrive Fig. 2 (3) position, this moment, crucible 18 entered in 900 ℃ the high temperature furnace 8, fed nitrogen 7 minutes, removed volatile constituent in the stove, weighed by balance, calculated the percentage composition of volatile component.By microcomputer the temperature of high temperature furnace 8 is controlled at 815 ℃ at last, aerating oxygen makes coal combustion, gets ash content until the fixed carbon after-flame, weighs and calculates the percentage composition of fixed carbon and ash content respectively.So far, first sample test finishes.Heating furnace and sample introduction dish are risen to Fig. 3 (1) position, start sample introduction motor 10, make sample introduction dish 12 turn over lattice, second coal sample crucible arrives test position, repeat said process, carry out next coal sample test continuously, the sample on the sample introduction dish all test finishes.
Fig. 3 embodiment adopts rack-and-pinion as elevating mechanism.As shown in Figure 3, with the rotation under motor 20 drives of tooth bar 21 meshed gears, and, drive heating furnace and the together lifting of sample introduction dish by crossbeam 17 simultaneously along tooth bar 21 liftings.
