The present invention relates to infrared carbon sulfur analyzer, specifically be meant the burner in the infrared carbon sulfur analyzer.
Background technology
The burner of infrared carbon sulfur analyzer adopts usually from crucible tray bottom oxygen carrier at present, and the analytical gas filtration fraction is arranged on the top of combustion tube, and crucible is at the middle part of combustion tube.Sample in the crucible is under the heating of high frequency coil, burning produces and to contain the high-temperature analysis air-flow of being with Mars in a large number and upwards flow through and be used to clean the metal plug of combustion tube and the screen pack of filtration fraction flows to analysis cell, metal plug and wire screen pack usually can be burnt out, and need often to change; The dust discharge pipeline is arranged on oxygen carrier pipeline bottom in addition, causes the oxygen carrier line clogging easily when cleaning, thereby influences the normal operation of instrument.The crucible carriage is fixed on the lift cylinder bar and can not arbitrarily takes off, and operation is made troubles.
Summary of the invention
Based on the problem that exists on the above-mentioned existing burner structure, burner provided by the invention is to solve avoids metal plug and wire screen pack to be burnt out, and effectively prevents the obstruction of oxygen carrier pipeline and the technical problem of being convenient to operate.
Burner of the present invention comprises: combustion furnace, burning jamb, analytical gas filtering head.Combustion furnace constitutes by accompanying interlayer in the middle of shell and the combustion tube, the periphery of combustion tube is wound with high frequency coil, the crucible of placing sample is arranged in the combustion tube, crucible twines the position by the high frequency coil that crucible tray is supported to combustion tube, the upper end of combustion tube connects with burning jamb, the lower end of combustion tube and transitional shell sealed attachment have one 90 ° of turning channels in the transitional shell, connect with the gas filtration head by pipeline.
Said burning jamb comprises: upper shell, lower house, and upper and lower casing constitutes the axial passage that cylinder, cylinder rod, combustion tube cleaning brush and oxygen blast mouth can be installed, and this passage communicates with combustion tube.Upper shell has a horizontal oxygen blowing channel, the cylinder rod side has a hole, this hole can communicate the vertical connection of oxygen blowing channel and cylinder rod internal channel, and the afterbody of cylinder rod is equipped with the oxygen blast mouth, constitutes one thus and passes through oxygen blowing channel, cylinder rod passage and oxygen blast mouth to the oxygen blown passage of combustion tube.The combustion tube cleaning brush is arranged on the periphery of top, the cylinder rod of oxygen blast mouth.At lower house one horizontal oxygen carrier passage is arranged, this passage communicates with axial passage is vertical.
Combustion tube cleaning brush and screen pack cleaning brush connect with cylinder by cylinder rod respectively, and cylinder is by solenoid control, have analyzed automatic combustion tube and the screen pack of cleaning behind the sample at every turn.
The crucible pallet is a double-deck cone structure.Transitional shell and crucible pallet are to connect with the sealing activity of the conical surface by cone between crucible tray and the crucible pallet, and the crucible pallet also is to connect with the activity of the conical surface by cone with cylinder rod.
The advantage of structure of the present invention is:
1. adopt at combustion furnace head oxygen carrier, changed the flow direction of burning jamb inner analysis gas, promptly analyze air-flow from top to bottom.Like this, the sample combustion generation contains the high-temperature analysis air-flow of being with Mars in a large number and flows downward without metal plug, and through the wire screen pack of flowing through after the long distance, metal plug and wire screen pack just can not burnt out, and can not influence the normal operation of instrument.
2. employing brings convenience for the placement sample with cone and cone match connection between crucible tray, crucible pallet and the cylinder rod head, and picking and placeing flexibly of crucible pallet makes it grey very convenient simultaneously.
3. in addition, dust discharge pipeline and oxygen carrier pipeline divide fully and are arranged, and have avoided the oxygen carrier line clogging.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is elaborated:
Burner of the present invention comprises: combustion furnace 1, burning jamb 2, analytical gas filtering head 3.Accompanying interlayer 104 in the middle of the combustion tube 103 of combustion furnace by shell 101 and winding high frequency coil 102 constitutes.Crucible 4 is placed on the crucible tray 5, the high frequency coil 102 that is supported to combustion tube 103 twines the position, the upper end of combustion tube connects with burning jamb 2, the lower end of combustion tube and transitional shell 6 sealed attachment, one 90 ° of turning channels 601 are arranged in this transitional shell, and the three-way device 304 by pipeline 7 and gas filtration 3 connects.
Said burning jamb 2 comprises: upper shell 201, lower house 202, and upper and lower casing constitutes the axial passage 207 that cylinder 203, cylinder rod 204, combustion tube cleaning brush 205 and oxygen blast mouth 206 can be installed, and this passage communicates with combustion tube 103.Upper shell has a horizontal oxygen blowing channel 208, the cylinder rod side has a hole 209, the afterbody of cylinder rod is equipped with oxygen blast mouth 206, when burner is worked, cylinder rises to cylinder rod this hole 209 is communicated oxygen blowing channel 208 with cylinder rod internal channel 211, constitutes one thus and passes through oxygen blowing channel, cylinder rod passage and oxygen blast mouth to the oxygen blown passage of combustion tube.At lower house 202 a horizontal oxygen carrier passage 210 is arranged, this passage communicates for 207 one-tenth 90 ° with axial passage.Can be by this passage to the combustion tube oxygen carrier, keep certain pressure in the combustion tube, sample combustion is produced contain in a large number the high-temperature analysis air-flow of being with Mars downwards through transition housing 6, pipeline 7 inflow gas filtering heads 3.
