Description
Technical Field
The utility model relates to an electric heating unit technical field, in particular to electric heating unit with stirring constant temperature liquid mixing device.
Background
The electric heating unit drives the mixed energy-gathering medium in the closed container through electric energy to generate a large amount of heat, and then the heat is transferred to the tail end of the heating system through a heat exchange system in the unit to achieve the purpose of heating. In actual work, the media that these are heated can take place temperature gradient layering phenomenon because of the action of gravity in the container, and the temperature of upper strata is high the temperature of lower floor is low promptly, and the unit will cause a large amount of calorific loss carrying out the heat exchange process like this to greatly reduced heat transfer effect has reduced the thermal efficiency of unit, influences the heating effect. At present, in order to solve the technical problem, the problem can be solved only by increasing the power of the unit or increasing the working time of the unit, but the heating operation cost is increased.
Disclosure of Invention
In order to solve the problem of the prior art, the utility model provides a reducible calorific loss has improved the electric heating unit that has the liquid mixing device of unit thermal efficiency.
The technical scheme of the utility model as follows:
the utility model provides an electric heating unit with stirring constant temperature liquid mixing device, is including preheating recovery water jacket, the airtight storehouse of medium in be equipped with hindering nature electric heating rod, the top in the airtight storehouse of medium be equipped with import and export, one side in the airtight storehouse of medium be equipped with preheating recovery water jacket, the opposite side in the airtight storehouse of medium be equipped with the dividing wall type heat exchange tube, the airtight storehouse of medium in be equipped with high temperature resistant electric screw agitator, the (mixing) shaft of electric screw agitator drive through the motor in the airtight storehouse outside of medium, the airtight storehouse of medium pass through pipe connection oil-gas separation jar, the pipeline between airtight storehouse of medium and the oil-gas separation jar on be equipped with 0.15 Mpa's explosion-proof valve.
The stirring shaft is provided with a stirring paddle.
The utility model provides a beneficial effect that technical scheme brought is:
the electric spiral stirrer is additionally arranged on the electric heating unit, so that the medium in the medium bin is fully mixed with the upper layer and the lower layer of the medium under the stirring of the electric spiral stirrer in the heating process, the temperature of the upper layer and the temperature of the lower layer are close to the same, the temperature gradient phenomenon of the medium is solved, the heat exchange effect is greatly improved, the heat loss is reduced, the heat efficiency of the unit is improved, and the energy-saving effect that the running cost is saved by 30-50% compared with that of the traditional electric heating unit is realized on the premise of achieving the same heating effect.
The explosion-proof valve and the oil-gas separation cylinder are arranged, when the pressure in the unit exceeds the set pressure, the high-temperature gas-liquid mixture in the unit breaks through the explosion-proof valve and enters the oil-gas separation cylinder to discharge high-temperature and high-pressure gas, and the unit still keeps closed operation, so that the safety protection effect is achieved.
