Description
Technical field
The present invention relates to dedusting, ash, impurity technical field, be specifically related to a kind of cleaning apparatus for hot environment and dedusting assembly.
Background technology
In float glass process, glass metal completes moulding process on tin liquor face, because mold temperature is at 600-1000 degrees centigrade, pure tin exists with liquid form, but at high temperature tin liquor is very easily oxidized to stannic oxide, float on tin liquor face with pulverized solid form, thus have a strong impact on glass production quality.Because of at high temperature to this floating tin ash cleaning difficulty, the instruments such as steel disc, cleek, rake are generally adopted regularly to be clawed by tin ash at present.
In order to clear up the problem of tin ash difficulty under solving high temperature, prior art such as Chinese patent CN2717948Y discloses a kind of high-temperature gas, the absorption refrigerating unit of dust, comprise negative pressure propulsion source, extraction pipe, fill the encloses container of liquid, cleaner head, wherein negative pressure propulsion source is by passing through variable valve, extraction pipe is communicated with the encloses container filling liquid, one end of extraction pipe to be stretched in encloses container and is made the mouth of pipe upwards, cleaner head is entered dirt pipe by air inlet and is communicated with encloses container, the front end that dirt pipe is entered in air inlet is connected with equalizer and is placed in the liquid of encloses container, the Main Function of equalizer makes the high-temperature gas of suction balancedly from its exhaust dust exhausting hole, enter cooling fluid.In the prior art, owing to adopting the direct air-breathing of power-driven pump to produce negative pressure, the high-temperature gas sucked from glass metal passage like this will through power-driven pump, and flowing through for a long time of such high-temperature gas can produce detrimentally affect to power-driven pump.In order to avoid such detrimentally affect, have employed the mode that cooling fluid is set in the prior art and the air of suction is cooled.But, there are some following defects in the prior art: 1, contacts with cooling fluid after high-temperature gas enters encloses container in actual use, cooling fluid moment bumping, produce a large amount of gas, if the gas that the gas produced siphons away more than vacuum pump, the pressure in encloses container is instantaneous transfers malleation to, and once form malleation, compressing cooling fluid is blowed back into extraction pipe by malleation, and flows in molten tin bath from the cleaner head of extraction pipe end, and this causes fatal impact by molten tin bath or glass production; 2, the prior art adopts the encloses container filling cooling fluid, and total is complicated, and cooling vessel is huge, mobile operational difficulty, impracticable in glass production.
Chinese patent literature CN204363900 discloses a kind of portable dust collector, its principle of work is using the negative pressure propulsion source of motor as suction cleaner, make the sweep-up pipe air inlet position of suction cleaner form negative pressure by motor rotation, thus the impurity absorption such as dust, the scraps of paper is entered in body of dust collector.But the suction cleaner of the prior art can not be applicable to dedusting under hot environment, and high-temperature gas enters after body of dust collector can cause major injury to the motor in body of dust collector through sweep-up pipe, causes motor to be scrapped.
To sum up, lack in currently available technology a kind of be applicable to hot environment under and in dust removal process, there will not be cooling liqs to flow backwards and glass production caused to the cleaning apparatus of disadvantageous effect.
Summary of the invention
Therefore, the object of this invention is to provide a kind of be applicable to hot environment under and in dust removal process, there will not be cooling liqs to flow backwards and glass production caused to the cleaning apparatus of disadvantageous effect.
For this purpose, the present invention proposes a kind of cleaning apparatus for hot environment, comprise
