In the embodiment, the remains 8 are stored in the coffin 7, the coffin 7 is placed in the refrigerating bin 102, the liquid nitrogen tank 6 is opened, and liquid nitrogen is transmitted into the refrigerating bin 102 by the liquid nitrogen pipeline 5 for refrigeration so as to carry out low-temperature refrigeration on the remains 8. By utilizing the principle of liquid nitrogen evaporation heat absorption, the temperature can be quickly reduced, and the remains 8 are prevented from being rotten.

In addition, the liquid nitrogen is used for cooling the ice coffin device, air in the coffin can be replaced by the nitrogen, and the dry nitrogen is not beneficial to bacterial reproduction and can also play a role in retarding decay.

Specifically, in order to control the discharge of liquid nitrogen, a manual air inlet valve 4 is arranged on the liquid nitrogen pipeline 5, and after an operator opens the manual air inlet valve 4, high-pressure liquid nitrogen stored in the liquid nitrogen tank 6 can enter the refrigerating bin 102 along the liquid nitrogen pipeline 5. Therefore, the ice coffin device in the embodiment does not need external electric energy in the refrigerating process in principle, and can enhance the applicability of the ice coffin device to realize continuous refrigeration, so that the ice coffin device is not easy to cause refrigeration failure due to accidental power failure in long-distance transportation lacking power supply like the electric refrigeration ice coffin.

Specifically, the refrigerating chamber 102 is provided with an insulating layer 111 for preventing the dissipation of cold.

In particular, in order to protect the environment, pollution is reduced. The coffin body 7 is made of paper coffin or wood coffin, and after the remains 8 are refrigerated, the coffin body 7 can be cremated with the remains 8. The coffin body 7 is designed as a disposable article, thereby ensuring that the ice coffin and the remains 8 are not polluted, keeping neatness, reducing the workload of cleaning and disinfecting the ice coffin and ensuring the reuse of the ice coffin. The coffin body 7 can be made of new materials or recycled wastes, can be cremated along with the remains 8 and does not produce chemical toxic waste residues and waste gases.

Specifically, in order to facilitate observation of the content of liquid nitrogen in the liquid nitrogen tank 6 and check whether the liquid nitrogen tank 6 is under safe pressure, the liquid nitrogen tank 6 is further provided with an instrument 601 for observing the liquid level and pressure of the liquid nitrogen tank, and the instrument 601 is specifically a liquid level meter and a pressure gauge.

Specifically, the installation position of the liquid nitrogen pipeline 5 is not limited to the outside of the ice coffin, and the liquid nitrogen pipeline can be arranged inside the ice coffin, so that the ice coffin is more attractive. The number of the air inlets of the liquid nitrogen pipeline 5 in the refrigerating bin 102 is not less than 4, and the number can be adjusted according to the refrigerating effect. The liquid nitrogen pipeline nozzle can be provided with a volatilization system such as a fan, so that the air flow in the refrigeration bin 102 can flow rapidly, and the rapid balance of the temperature can be realized.

Specifically, all be equipped with universal wheel 105 in cabinet body 1 bottom four corners, universal wheel 105 can conveniently be used for the removal and the transportation to the cabinet body 1.

Referring to fig. 4-5, in some embodiments, a temperature zone partition plate 2 is disposed in the refrigerating chamber 102, and the refrigerating chamber 102 is divided into a head temperature zone 113 and a trunk temperature zone 112 by the temperature zone partition plate 2 located at the neck of the remains 8; the liquid nitrogen pipeline 5 is divided into a head cold-conveying pipeline 501 and a trunk cold-conveying pipeline 502, the head cold-conveying pipeline 501 is connected into the head warm area 113, and the trunk cold-conveying pipeline 502 is connected into the trunk warm area 112.

Because a notifier is generally required to be held before the remains 8 are cremated, the faces of the remains 8 are made up when the notifiers are given, and the cooling speed of the conventional compressor ice coffin is low; if a high-power compressor is used, the cooling rate can be improved, but the face temperature is too low (lower than 0 ℃ for makeup), if a low-power compressor is used, the surface temperature of the remains 8 can be controlled to be 4-5 ℃, the makeup on the face is met, the surfaces of the remains 8 cannot decay within three days or four days, but the insides of the remains 8, particularly the insides of the abdomens, decay rapidly, body odor can be emitted and body water can be exposed, and the moisture of air in the coffin is not beneficial to the preservation of the remains 8, so that the talent type appearance is poor.

In this embodiment, as can be seen from the practical data of refrigerating the remains 8, the temperature of the trunk warm area 112 should be controlled to be lower than-18 ℃ in order to rapidly cool the interior of the remains 8, especially the abdomen, and prevent putrefaction. In order to meet the requirements of makeup on the face of the remains 8, the temperature of the head warm area 113 needs to be controlled to be 4-5 ℃. Therefore, the remains 8 is divided into a head warm area 113 and a trunk warm area 112 by the warm area partition plate 2, so that the liquid nitrogen discharge amount of the head cold conveying pipeline 501 and the trunk cold conveying pipeline 502 is respectively controlled, and the temperature of the two warm areas is respectively controlled. Therefore, the makeup of the face can be realized (the made up remains 8 can be placed in the ice coffin, and the ice coffin with the subareas can not influence the makeup of the remains 8), and the temperature area partition plate 2 is taken off to ensure that the temperature of the whole refrigerating chamber 102 is consistent when the ceremony is distinguished.

In this embodiment, since the temperatures of the head temperature region 113 and the trunk temperature region 112 cannot be accurately controlled only by manually controlling the discharge amount of liquid nitrogen from the liquid nitrogen pipeline 5, the temperature control assembly 3 is constituted by additionally providing the temperature sensor 306, the solenoid valve 303, and the control panel 302. Temperature parameters of the head temperature area 113 and the trunk temperature area 112 are collected in real time by using the temperature sensor 306 and fed back to the control panel 302, and the control panel 302 controls the on-off or opening size of the head cold transmission pipeline 501 and the trunk cold transmission pipeline 502 by controlling the electromagnetic valve 303, so that the accurate temperature control of the head temperature area 113 and the trunk temperature area 112 is realized by accurately controlling the discharge amount of liquid nitrogen.

And because the ice coffin device adopts liquid nitrogen refrigeration to replace the traditional electricity refrigeration, the power of the needed power supply unit is very low, the long-time operation without external power supply can be ensured, and the ice coffin device is greatly convenient to operate on a transport vehicle and other use environments without high-power external power supply facilities.

Besides, the control panel 302 can be electrically connected to the level gauge, the pressure gauge, and other meters 601 of the liquid nitrogen tank 6, so that the control panel 302 can also display and monitor the liquid level height and the pressure parameters of the liquid nitrogen tank 6 in real time.

Specifically, the temperature sensor 306 is an infrared temperature sensor.

Preferably, a heating device 301 is disposed in the head temperature region 113, and the heating device 301 is electrically connected to the control panel 302. Since the remains 8 themselves are also heat-conducting, in order to prevent the temperature of the torso warm area 112 from being excessively conducted to the head warm area 113, a heating device 301 controlled by a control panel 302 is provided in the head warm area 113. The temperature of the head temperature region 113 can be effectively controlled within a temperature range set by the system (such as 4-5 ℃) by mutually circulating the heating device 301 and liquid nitrogen refrigeration.

The antifreeze liquid cooled by the liquid nitrogen flows into the ice quilt 13 under the action of the water pump 10, the ice quilt 13 wraps the trunk of the remains 8, the antifreeze liquid flows in the ice quilt 13 through the cold guide pipeline 9, contact refrigeration is realized on the trunk of the remains 8, the refrigeration temperature is low, the temperature of the inside of the remains 8 can be quickly reduced, and the decay speed of the remains 8 is controlled. And because the head of the remains 8 is not wrapped by the ice quilt 13, the cold storage of the remains is realized by heat conduction of the remains 8 and the cold energy dissipated by the ice quilt 13 in the cold storage bin 102, and the temperature of the remains is higher than that of the body, so that the makeup requirement is met.

And the cold guide pipeline 9 is in circulating refrigeration, and the low-temperature antifreeze flows back to the heat exchanger 12 for re-cooling after the ice is circulated in the ice cover 13, so that the circulating refrigeration is realized.

Specifically, the antifreezing solution is saline water with the salt content of 20% -30%, and the saline water with the concentration can not be frozen at the temperature of minus 20 ℃.

Preferably, the front material of the ice quilt 13 is cotton or down feather with a heat preservation function, and the cotton or down feather can be used for storing the low temperature of the cold conducting pipeline 9 in the ice quilt 13 to be transited and dissipated in the refrigerating chamber 102, so that the temperature in the refrigerating chamber 102 is too low, and the head temperature of the remains 8 is too low.

Through the temperature data fed back by the temperature sensor 306 in the refrigerating chamber 102, the control panel 302 controls the electromagnetic valve 303 to control the discharge amount of liquid nitrogen of the temperature control pipeline 11 or control the opening and closing of the heating device 301, thereby controlling the temperature in the refrigerating chamber 102 and adjusting the head refrigerating temperature of the remains 8. Specifically, when the temperature sensor 306 measures that the temperature in the refrigerating compartment 102 is higher than 4 ℃, the temperature control pipeline 11 is opened to discharge a small amount of liquid nitrogen, the liquid nitrogen is dripped into the refrigerating compartment 102 to reduce the temperature, and if the temperature in the refrigerating compartment 102 is too low, the heating device 301 is opened to raise the temperature again.
