Description
Technical Field
The utility model relates to a heating technology of an IBC ton barrel, in particular to a phase change heating device in the transportation process of an explosion-proof ton barrel.
Background
IBC ton barrels (containerized barrels) are a requisite tool for modern storage and transportation of liquid products. The packaging barrel is formed by combining an inner container and a metal frame, wherein the inner container is formed by blow molding high-molecular-weight high-density polyethylene, and has high strength, corrosion resistance and good sanitation. The center of the top of the IBC ton barrel is provided with a vent hole, and Kong Zhoukai is provided with internal threads.

Therefore, the IBC ton barrel needs to be insulated and heated in middle-long distance transportation.
At present, heating of the IBC ton barrel is mainly performed by using an electric blanket or an electric jacket, power is required to be continuously supplied to the ton barrel electric blanket and the electric jacket in the transportation process (such as Chinese patent with publication number CN219287742U, CN219278379U, CN219216183U, CN218550209U and the like), and potential safety hazards are easily caused by using electric heating if transported liquid is inflammable and explosive liquid in the transportation process.

The utility model is realized by adopting the following technical scheme: the phase change heating device comprises a phase change material storage barrel made of heat conducting materials, wherein paraffin phase change materials are filled in the phase change material storage barrel, external threads are formed on the outer wall, close to a top port, of the phase change material storage barrel, an upper cover is fixedly arranged at the top port of the phase change material storage barrel, a heating rod and a bimetal temperature control switch which extend into the phase change material storage barrel are arranged at the bottom of the upper cover, a temperature display meter, a junction box and a hanging ring are arranged at the top of the upper cover, and a waterproof socket is fixed on the junction box; the power supply loop of the heating rod is arranged in the junction box, and the normally closed switch of the bimetal temperature control switch is connected in series on the power supply loop of the heating rod.
Before use, the phase change heating device in the process of transporting the explosion-proof ton barrel is placed on a frame for preheating. And a preheating power supply cable is inserted, the bimetal temperature control switch is closed due to lower temperature, the heating rod is electrified, the heating rod continuously heats the paraffin phase-change material, and the paraffin phase-change material absorbs heat and gradually melts. When the temperature reaches the preset temperature (60 ℃), the bimetal temperature control switch is turned off, the heating rod is powered off, and the heating is stopped. And the phase change heating device finishes preheating in the transportation process of the explosion-proof ton barrel.
The phase change heating device is lifted by the lifting ring in the transportation process of the pre-heated explosion-proof ton barrel by using the crane, inserted into the vent hole of the IBC ton barrel and screwed by threads. The IBC ton bucket can be loaded and transported. The paraffin phase-change material in the phase-change heating device releases latent heat of melting in the process of transporting the explosion-proof ton barrel, and continuously heats the liquid in the IBC ton barrel at about 51 ℃. Prevent the liquid in the IBC ton barrel from being cooled to cause solidification or viscosity increase. The paraffin phase-change material is gradually solidified after releasing the latent heat of melting, and heating is completed after all solidification.
Further, a safety plug is arranged on the upper cover; the safety plug is connected in series with the power supply circuit of the heating rod. The upper port of the phase change material storage barrel is connected with the upper cover through a fastening bolt. The phase change heating device storage rack comprises a shell, and a plurality of storage openings for accommodating the phase change material storage barrels are formed in the top of the shell. The phase change material storage barrel is made of 304 stainless steel.
If the bimetal temperature control switch fails to cause continuous heating of the heating rod, the paraffin phase-change material is caused to boil at too high temperature, the safety plug is sprung out under the internal pressure of more than 1.5 times of atmospheric pressure, the internal pressure is released, the power supply is cut off, and the safety of the phase-change heating device in the transportation process of the explosion-proof ton barrel is ensured.
The utility model avoids the potential safety hazard caused by heating the explosion-proof ton barrel by a continuous external power supply heating mode in the past, and effectively ensures that the liquid in the explosion-proof ton barrel is not frozen by slowly releasing heat of the phase-change material. The whole device has simple structure and safe use.
