Description
Technical field
This utility model relates to a kind of eye syringe, relates more specifically to a kind of antifreeze eye syringe.
Background technology
A lot of production operation places; Comprise that industry operating personnels such as chemical industry, petrochemical industry, Coal Chemical Industry, iron and steel, medicine can touch the place of media such as high temperature, low temperature, poisonous, corrosivity; Mostly relate to materials such as each type high temp, low temperature, poisonous, harmful or corrosivity, these materials leakage, maloperation appear, obstruction is handled and splashing in process for preparation all might hurt the Field Force.In case injury takes place, very first time emergent management is most important to alleviating extent of injury timely and effectively, also can play irreplaceable positive role to further specialty treatment subsequently.At present each production operation place generally is employed in the on-the-spot scheme that eye syringe is installed and comes in time to wash away the materials such as these high temperature, low temperature, poisonous and harmful and corrosivity of splash to certain position of health especially eye, and the used flushing water of eye syringe generally adopts drinking water (being the life water in production operation place).
Eye syringe is arranged on apart from the potential danger source the nearer place, ground of maybe possibly causing danger usually, such as soda acid holding vessel, chemical assistant preparing tank, the easy zone of leaking of corrosivity material.Following 2 points are generally considered in the position that is provided with of eye syringe: the one, and when taking place, the splash accident conveniently washes nearby; The 2nd, owing to the personnel's meeting that receives splash is more nervous because of fear, the uncomfortable spirit that makes, so eye syringe need be installed in the place that the wounded is easy to find.Therefore, if the potential danger source is an outdoor location, then eye syringe also need be installed in outdoor environment.In cold district or cold season, the antifreeze of eye syringe is the problem that each manufacturer, the production operation place of using eye syringe such as factory all pay close attention to very much.The antifreezing measures of existing eye syringe also are varied, take steam tracing or forms such as hotwater tracing or electric tracing basically.Fig. 1 shows existing a kind of antifreeze eye syringe; As shown in Figure 1; Eye syringe 1 comprises the wash tub pipe 2 that has flushing water shower nozzle 3; Wherein before flushing water shower nozzle 3, on wash tub pipe 2, have flushing water control valve 4, and behind this flushing water control valve 4, have the wash tub pipe after being used for the emptying control valve residual water drench valve 5, steam that this eye syringe 1 is taked to laterally arrange with wash tub pipe 2 or hotwater tracing manage 6 and/or the mode of directly on wash tub pipe 2, twining electric tracing resistance wire 9 realize preventing that flushing water from freezing stifled purpose; Wherein adopting steam or hotwater tracing to manage under 6 the situation; For reaching required purpose, manage 6 import 7 (being provided with control valve 10A) from steam or hotwater tracing and feed steam or hot water, and flow out lime set or hot water from its outlet 8 (being provided with control valve 10B); And adopting under the situation of twining electric tracing resistance wire 9, for reaching required purpose, through the resistance wire energising is heated the flushing water in the wash tub pipe 2.Though this existing eye syringe 1 can play in practice and prevent winter to freeze stifled phenomenon; But there is other problem in this eye syringe; For example wherein companion's thermal source need be in continuous running status, and the used flushing water of eye syringe only just can use when accident occurring.Flushing water is not flow and be resting state in the times in the overwhelming majority, therefore accompanies thermal source to need constantly heating eye syringe system and makes the temperature of the temperature of flushing water near companion's thermal source.In actual production process, find; Angle and good effect of freezing protection are considered more easily from originating; The flushing water section temperature of using steam tracing is probably more than 80 ℃; Use hot water or electrically heat tracing flushing water section temperature probably more than 60 ℃, pyritous water like this drenches can bring on the human body scalds so secondary injury.Using electric tracing not only is to exist long-term heating to be in the phenomenon of immobilized flushing water and to make the flushing water temperature higher equally, and will lay power supply specially and increase prevents line services such as insulation damages, short circuit, electric shock.In addition, owing in actual motion, need long-term heating to be in immobilized flushing water, so the problem that also existence wastes energy and energy utilization efficiency is low.
Therefore, need to satisfy and prevent winter to freeze purpose stifled, the bursting by freezing phenomenon and can prevent simultaneously because the novel antifreeze eye syringe of the too high secondary injury of scald that causes of the hot temperature of companion.
The utility model content
The purpose of this utility model is to improve to existing anti-freeze type eye syringes in production operation place such as production operation place such as chemical industry, petrochemical industry, coal system oil, Coal Chemical Industries; Antifreeze with effective realization eye syringe flushing water; The secondary injury of avoiding existing anti-freeze type eye syringe to cause simultaneously, the security performance of raising eye syringe.Especially, the existing eye syringe of solution is spent height because of existing companion's rinse water temperature that hot mode brought human body is brought the problem of scald, and improves energy utilization efficiency.
Therefore; This utility model provides a kind of antifreeze eye syringe that is used for the production operation place; Comprise: wash tub pipe, it has flushing water shower nozzle and flushing water control valve, and between flushing water shower nozzle and flushing water control valve and have the valve of pouring near flushing water control valve place; And freeze box; It has circulating water intake and circulating water outlet; And has the recirculated water control valve near circulating water intake and circulating water outlet place respectively; Wherein, freeze box is sleeved on the wash tub pipe outside, and the temperature used from the production operation place of freeze box internal recycle at 20～40 ℃ recirculated water with antifreeze to flushing water.
In one embodiment, wash tub pipe has curved end, and the flushing water shower nozzle is arranged on the end of curved end.
In one embodiment, circulating water intake is arranged on the bottom of freeze box, and circulating water outlet is arranged on the top of freeze box.
In one embodiment, freeze box is the ring-shaped sleeve of the closed at both ends that is made up of interior pipe and outer tube.
In a preferred implementation, the diameter of inner pipe of freeze box is 5～30mm, and outer tube diameter is 50～100mm.
In one embodiment, the length of freeze box is 0.5-3m.
In one embodiment, freeze box is sleeved on through binding agent is bonding with wash tub pipe.
In one embodiment, freeze box is sleeved on through welding with wash tub pipe.
In one embodiment, freeze box and wash tub pipe are whole formation.
