Description
Technical field
A kind of vertical lift type antifreezing fluid spraying device of the present invention and using method thereof, belong to Machine Design and control technology field, be specifically related to a kind of vertical lift type antifreezing fluid spraying device of the unit train compartment inner surface that anti-icing fluid evenly can be sprayed onto efficiently differing heights and the technical scheme of using method thereof.
Background technology
Railway is the main channel of coal in China transportation, and the outward transport coal of Coal Transport enterprise contains moisture, can freeze the car situation when transporting in the winter time.Coal fortune is frozen the car problem and is all brought enormous economic loss to departments such as ore deposit, road, ports.The main loss form has: freeze the residual coal of car and lose, freeze the residual coal round transport of car with wagon flow and cause transport power waste, cleaning to freeze the used fund of the residual coal of car, freeze car and cause the holdup time lengthening, influence that rolling stock normally has enough to meet the need, handling capacity descends, influence the performance of conevying efficiency, the benefit that also makes simultaneously the owner of cargo and railway is subjected to direct influence because of the reduction of conevying efficiency.In addition, freeze the residual coal of car and lose with wagon flow railway environment along the line is polluted, thereby freeze the car problem and also become environmental issue.The moisture that reduces coal is to solve the effective ways that freeze, but floor space is big, investment is big because the dehydration of coal and drying are handled, expense is high, thereby most of coal preparation plant does not have the drying plant.Once adopted many methods to solve both at home and abroad to freeze coal and unloaded, as vibrate, knock, methods such as explosion, defrozing silo, magnetic field impulse vibration, and these method labour intensity are big, cost is high, efficient is low, fail fundamentally to solve to freeze the coal problem of unloading.In view of above all situations, still generally adopt the method for spraying anti-icing fluid to solve now and freeze the coal problem.Coal in China is produced and is mainly concentrated on cold northern area, generally carries out coal output by coal preparation plant, and its outward transport coal is mainly based on coal blending, and the situation of freezing of coal blending and the free moisture of coal, particle composition have much relations.With the initial mark that the sticking end and little caking freeze as coal, wherein the sticking end, the caking phenomenon of smalls are more serious, and the end phenomenon of freezing of coal washing piece often takes place, and the situation of freezing of mixed coal is by the fit form decision of smalls and coal washing piece fully.The form of freezing car mainly shows as the sticking end, wall built-up and caking, when ambient temperature is low, at first produces the sticking end and wall cling phenomenon, along with the heat conduction, forms caking from freezing gradually outside to inside, and because moisture permeates downwards, phenomenon of the sticking end is particularly serious.General serious caking is to take place under the low-down situation of temperature, and the sticking end and wall built-up are as long as environment temperature all might take place below freezing.Therefore, each transports coal enterprise in the winter time mainly to prevent the sticking end and wall built-up, only sneaks into anti-icing fluid in just by coal under the low-down situation of temperature and prevents caking phenomenon.For preventing the sticking end and wall built-up, anti-icing fluid must evenly cover whole five inner surfaces in compartment, comprises bottom surface, compartment, two sides and two end faces, and minimum sprinkling amount changes along with variation of ambient temperature, and the low more requirement sprinkling of temperature amount is big more.Along with antifreeze the require increasingly stringent of railway transportation department, require each production and fortune coal enterprise must prevent to freeze the car phenomenon when railway is transported coal in the winter time and take place unit train.At present, each is transported the coal corporate boss and will adopt sprinkling anti-icing fluid to prevent to freeze the car phenomenon, and the anti-icing fluid spray pattern that adopts is also varied, can classify as artificial sprinkling, spread by hand and sprinkling automatically.The artificial sprinkling comprises that hand-held jar manually sprays and pistol manually sprays, and this mode is sprayed the cost height, spray effect is poor, and workman's working condition is abominable, labour intensity is big, the activity duration is long.Spread by hand is to spray by the Artificial Control valve, and nozzle location maintains static during sprinkling, and this mode workman's working condition is slightly improved, but spray effect is still very poor, and have the sprinkling dead angle, and can not in time stop in non-sprinkling district spraying, cause the anti-icing fluid waste.Automatically sprinkling can be sprayed anti-icing fluid automatically according to car position, has improved the utilization rate of anti-icing fluid, cuts the waste, and reduces labour intensity.Automatically spraying is the developing direction that anti-icing fluid sprays, but there are problems in design at present and the automatic sprinkler system that using imperfection still, can not accurately stop to spray as connect the neutral gear place in the compartment, causes the corrosion of anti-icing fluid waste and coupling hook; Because the mobile of compartment makes the compartment front/rear end spray inhomogeneous even generation sprinkling blind area; When variation of compartment translational speed or variation of ambient temperature, can not in time adjust the sprinkling amount, make the sprinkling amount excessive or too small, perhaps waste anti-icing fluid or cause and freeze the car phenomenon; The designs of nozzles position is unreasonable, and spraying liquid chiasma interference causes sprinkling inhomogeneous; Along with compartment specification and height change, can not adjust nozzle location, cause the anti-icing fluid of sprinkling to overflow the compartment and cause waste or anti-icing fluid can not cover the compartment upper side and cause and freeze car; And flusher uses line clogging problem after the short time.
