Technical field
The utility model relates to the freezing field of high-pressure rubber pipe, refers to a kind of temperature automatically controlled high-pressure rubber pipe liquid nitrogen frozen device especially.
Background technology
In the high-pressure rubber pipe production process, sebific duct pipe embryo is carried out freezing, carry out again that steel wire twines and establishment.Used freezing equipment mainly is the refrigerator of compressor cooling at present, has the equipment investment height, and the operation energy consumption height is little between the freeze space, shortcomings such as follow-up maintenance complexity.Defectives such as part foreign capitals or joint venture use liquid nitrogen frozen in addition, though temperature controller is also arranged, exist temperature uncontrollable, and production target control is unstable, and the variations in temperature interval is big.
The utility model content
The utility model proposes a kind of temperature automatically controlled high-pressure rubber pipe liquid nitrogen frozen device, solved the problem of sebific duct pipe embryo refrigerating effect difference in the prior art.
The technical solution of the utility model is achieved in that a kind of temperature automatically controlled high-pressure rubber pipe liquid nitrogen frozen device, comprise liquid nitrogen pipes, control system and refrigerating chamber, described control system comprises pneumatic control valve, temperature sensor, temperature controller, time controller; Described liquid nitrogen pipes connects described refrigerating chamber by described pneumatic control valve; Described temperature sensor connects described temperature controller; Described temperature controller connects described time controller; Described time controller connects described pneumatic control valve; Described temperature sensor is positioned at described refrigerating chamber.
As optimized technical scheme, described pneumatic control valve enters the switching device of described refrigerating chamber for the control liquid nitrogen; Described pneumatic control valve comprises magnetic valve, the pneumatic operated valve that is connected with described magnetic valve.
As optimized technical scheme, described refrigerating chamber is the cast device; Described freezer indoor wall fixedly has heat-insulation layer.
The utility model is compared the beneficial effect that produces with background technology:
1, energy-conservation, the energy-conservation 30%-50% of ratio piston compressor type refrigerating plant;
The temperature acute variation of the liquid nitrogen frozen device of general control system can not appear in 2, stable performance;
3, control simply, need not personnel's field control, but continuous operation after regulating is regulated automatically.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below, apparently, accompanying drawing in describing below only is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.

The specific embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, a kind of temperature automatically controlled high-pressure rubber pipe liquid nitrogen frozen device, comprise liquid nitrogen pipes 1, control system and refrigerating chamber 6, wherein, liquid nitrogen pipes 1 is made by stainless pipe, be connected with liquid nitrogen storage tank 7, liquid nitrogen pipes 1 mainly is to carry liquid nitrogen to refrigerating chamber 6, the temperature of control system monitoring refrigerating chamber 6, and control refrigeration, control system comprises pneumatic control valve 2, temperature sensor 5, temperature controller 4, time controller 3, and liquid nitrogen pipes 1 connects refrigerating chamber 6 by pneumatic control valve 2; Temperature sensor 5 connects temperature controller 4; 4 connect hours of temperature controller controller 3; Time controller 3 connects pneumatic control valve 2; Temperature sensor 5 is positioned at refrigerating chamber 6.
Operation principle: at first write the temperature of refrigeration by the staff to temperature controller 4, write time and the refrigeration interbody spacer time of each refrigeration to time controller 3; Start refrigeration then, after beginning refrigeration, control system is obtained freezer temperature by temperature controller 4, and compare in temperature is set, refrigerating chamber 6 temperature drop to temperature is set before, temperature controller 4 is made refrigeration and is judged, and send signal to time controller 3, time controller 3 is passed to magnetic valve in the pneumatic control valve 2 with signal, after magnetic valve is opened after obtaining the refrigeration signal, operated pneumatic valve is opened, liquid nitrogen enters refrigerating chamber 6 by liquid nitrogen pipes 1, the high-pressure rubber pipe pipe embryo in the refrigerating chamber 6 is once freezed, after once refrigeration is finished, through a bit of time, refrigerating chamber 6 temperature are stabilized in a temperature again, if time temperature reaches temperature are not set, and control system repeats above-mentioned process of refrigerastion, through a plurality of process of refrigerastions, temperature reaches temperature is set in the refrigerating chamber 6, and temperature controller 4 judgements stop refrigeration, and refrigeration finishes.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
