Technical field
The utility model relates to test refractory material and other Inorganic Non-metallic Materials and resist deteriorate high-temperature abrasion test machine with scouring capability of material friction, particularly a kind of tail gas cooling purifying device of refractory material high-temperature abrasion test machine under hot conditions.
Background technology
Refractory material and other Inorganic Non-metallic Materials under hot conditions, resist the material friction deteriorate and scouring capability be its important physical property and serviceability.
The China and the U.S. still do not have refractory material high-temperature abrasion test device and high-temperature abrasion test method standard so far.
British Standard " mensuration of the index that resistance to wears under 1400 ℃ of high temperature of BS 1902:saction 4.7:1985 " has been stipulated the assay method of refractory brick or the refractory material test specimen wear resistance (abrasion index) in room temperature to 1400 ℃.The wear testing device comprises: 1. the gravity feeding system is made up of the wheel of a funnel and a motor-driven with groove, and abrasive material is stored in funnel, and can fall to entering groove continuously, by the wheel freely falling body whereabouts of motor-driven with groove; Feeding system can be regulated in the horizontal, so that main abrasive flows is passed the central metal pipe of below and is not contacted the central metal inside pipe wall, guarantee that abrasive material impacts on the sample with the impulsive force of freely falling body, the pipe that a small amount of discrete abrasive material passes the outer, coaxial heart enters gatherer.2. the heating element heater of sample heating furnace is straight shape silicon carbide rod, mainly is distributed in two inboards of heating furnace, installs on the horizontal direction; An alundum tube is installed on the top vertical direction of heating furnace, and alundum tube is connected with the central metal pipe of feeding system; Oven inner liner is built into fireclay insulating refractory, in the face of the back wall of sample is protected in order to avoid impaired with the corundum plate; Sample tilts 45 ° to be supported on the fire door refractory material of burner hearth inlet; Furnace temperature is measured with platinum-platinum 13% rhodium thermocouple of band protective casing; The abrasive material that impacted sample passes the pipe arrival gatherer (dish) of furnace bottom, by Venturi tube abrasive material is drawn into an electric blower again, is recycled to batch meter with cyclone separator.
The abrasion tester of regulation comprises in the JIS " JIS R 2252-1:2007 refractory products abrasion test method part 2 high-temperature abrasion test method ": 1. sample heating-furnace body and function refractory material is built into, one side is provided with the burner noz(zle) hole, oxygen-propane burner is installed in the hole, the upright refractory material sample of installing of the opposite side wall upside in burner noz(zle) hole reaches test temperature with the back side to the test surfaces (shock surface) of oxygen-propane heating sample test surfaces (shock surface); 2. abrasive material preheating device electrical heating, thermocouple temperature measurement, abrasive material are ceaselessly stirred by the stirring system of driven by motor in warm, when reaching the temperature of regulation, flow out through flowing out switch freely falling body under the gravity effect; 3. the free-falling abrasive material of sample chamber that weares and teares falls into the thrower impeller, and the thrower impeller rotates at a high speed, and abrasive material is thrown away at a high speed, and the experience wear nozzle is jetted to heating furnace and finished on the sample testing face (shock surface) of heating.
In the normal temperature abrasion wear test machine of the China and the U.S., because of its normal temperature, no high-temperature tail gas cooling purifying device.
The refractory material high-temperature abrasion test machine of Britain is without compressed air, and the tail gas that test is produced is very few, so there is not the tail gas cooling purifying device; And in the high temperature wear test sample devices of Japan, sample heating furnace oxygen-propane burning heating sample, its tail gas directly is disposed in the air, does not deal with, and is unfavorable for environmental protection and heat energy utilization.
Summary of the invention
The purpose of this utility model is to overcome the deficiency that high-temperature tail gas that test produces does not deal with, and a kind of tail gas cooling purifying device of refractory material high-temperature abrasion test machine is provided.
The purpose of this utility model can take following technical scheme to realize: described tail gas cooling purifying device comprises housing, in housing, be provided with tail gas cooling and purifying pipeline, in tail gas cooling and purifying pipeline outer setting cooling pipe is arranged, housing is provided with gas inlet and tail gas outlet, the tail gas outlet of gas inlet one end and trial furnace burner hearth is connected, and the other end is connected with the import of tail gas cooling and purifying pipeline; The outlet that tail gas exports an end and tail gas cooling and purifying pipeline is connected, and the other end connects the control of dust cloth bag; The outlet of cooling pipe import and cooling pipe is set on housing.
Recirculated water or refrigerating gas are set in the described cooling pipe.
Advantage of the present utility model: the exhaust emissions at testing machine is partly installed cooling purifying device, has not only avoided the pollution of high-temperature tail gas to air, has protected environment, and can reclaim the heat of tail gas, has reduced energy loss.
