Description
One, technical field
The present invention is used for the swing-arm type antifreezing fluid spraying device of two-way traffic unit train, belong to Machine Design and control technology field, be specifically related to a kind of can be with anti-icing fluid from the liftoff antifreezing fluid spraying device that evenly is sprayed onto five surfaces in the unit train compartment of nozzle low coverage.
Two, background technology
The northern China winter weather cold, the coal of railway transportation and breeze and other items easy freezing in car, 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.
The basic outlet that solution is freezed is to reduce the moisture of coal, and the moisture of control coal mainly relies on dehydration, dry run.Because the drying plant investment cost is bigger, generally account for about the 10%-20% of coal preparation plant's gross investment, thereby most of coal preparation plant does not have the drying plant.The drying and dehydrating of coal preparation plant does not also cause enough attention at home, uses also not general.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, the cost height, efficient is low, fails fundamentally to solve to freeze the coal problem of unloading.In view of above all situations, serve as to solve the main means of freezing coal still now to spray anti-icing fluid.
Coal preparation plant's 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 original form of freezing car is the sticking end, is wall built-up, caking then.Caking is the main cause that is difficult to unload, and this phenomenon mainly occurs in ambient temperature when low.The moisture of coal increases from top to bottom in the jimmy, so the situation of freezing of coal is deepened from top to bottom in the compartment.Wall cling phenomenon also increases from top to bottom gradually.Therefore, for preventing the sticking end and wall built-up, the main sprinkling position of anti-icing fluid is at the bottom of the car and the latter half of side board, and must be evenly.The first half sprinkling amount of sidewall can be less relatively, and especially the probability freezed by top of side board is less, and the sprinkling amount can reduce.
At present, the spray pattern to anti-icing fluid mainly contains two kinds: the artificial sprinkling and sprinkling automatically.The artificial anti-icing fluid situation of spraying is very simple, be that anti-icing fluid is carried by pump, be vaporific ejection through spray gun, operator's pistol sprays anti-icing fluid to bottom of the empty wagons skin before coalingging and sidewall, and in the process of coalingging, the coal seam is sprayed, its effect is very undesirable, main cause be spray very inhomogeneous, the spray less than the place still can freeze, do not reach the requirement of coal conveyor, and workman's working condition is abominable, and labour intensity is big, and the activity duration is long.
Some coal preparation plants also design and have used simple and easy sprinkling system, promptly adopt static pressure or hydraulic pump to carry out manual operations by simple and easy pipeline: when having railway carriage to enter, to open stop valve manually and begin hydrojet; When railway carriage rolls away from, close stop valve manually and stop hydrojet.Because a row train has a lot of railway carriages, and will adorn a lot of row trains in one day, so workload is very big, and very easily causes the waste of anti-icing fluid.
Also have some coal preparation plants to design automatic sprinkler system, increased automatic control section, utilize several photoelectric sensors, measure the railway carriage position, and hydrojet is controlled, save artificial purpose to reach, though effect is better than artificial sprinkling, but still have weak point: on the one hand, its shower nozzle is translation-angle automatically, can not guarantee the even sprinkling of railway carriage inwall.On the other hand; because this automatic sprinkler system need satisfy the regulation of the railway fundamental construction clearan ce of stipulating among the standard GB 146.2-83; security needs when guaranteeing that rolling stock passes through; cause flusher too high thus apart from the orbital plane height; still cause the spray effect of railway carriage inwall inhomogeneous, serious waste anti-icing fluid phenomenon.
