Abstract
A high-efficient air suction and heating device in the process of vacuuming the interlayer of a cryogenic liquid tank comprises a heating chamber (1), an aspiration channel (2), an exhaust fan (3) and an air outlet pipe (4). An air inlet of the aspiration channel (2) is positioned in the heating chamber (1); an air outlet of the air outlet pipe (4) is communicated with the heating chamber (1); and an air inlet thereof is communicated with an air outlet of the exhaust (3). The device has the advantages that an air exhaust device is arranged, so that the exhaust fan exhausts the cool air inside an inner tank body, and the hot air in the heating chamber can enter the inner tank body through a drain pipe of the inner tank body; and the heating of the inner tank body has the advantage that since the air exhaust device is arranged, an outer tank body and the inner tank body can be heated at the same time, thereby effectively improving the vacuuming effect of an air pump.
Description
Technical field
The utility model relates to low temperature liquid transportation semi trailer tank body process equipment field.
Background technique
The low temperature liquid transportation semi trailer tank body mainly is made up of interior tank body 5 and outer tank body 6 at present, and interior tank body is installed in the outer tank body.Mezzanine space between interior tank body and the outer tank body is the vacuum shape.When making can bodies, shape need be evacuated the interlayer between interior tank body and the outer tank body.Help the tank body insulation.When vacuumizing,, need tank body is heated in order to improve pumping efficiency.The existing heating equipment of bleeding is made up of heating chamber and vacuum pump 7; The exhaust tube suction port end of vacuum pump is positioned at heating chamber, during use, tank body is put into heating chamber, the exhaust tube suction port is communicated with interlayer between interior tank body and the outer tank body, start vacuum pump and bleed, and heating chamber is warming up to about 140 ℃, under this temperature, pumping efficiency is higher, and effect is better.But externally jar heating of heating, internally the effect of tank body heating is bad, because interior tank surface is surrounded by thermal insulating material, thereby can't reach the optimum efficiency that heating is bled.
Summary of the invention
The purpose of this utility model is bled the above-mentioned deficiency of heating equipment and the heating equipment of efficiently bleeding in a kind of cryogenic liquide jar interlayer vacuum is provided at existing cryogenic liquide jar exactly.
The utility model comprises heating chamber 1, and it also has suction pipe 2, induced draft fan 3, and the intake grill of suction pipe 2 is positioned at heating chamber 1, and exhaust outlet communicates with the intake grill of induced draft fan 3.It also has air outlet tube 4, and the exhaust outlet of air outlet tube 4 communicates with heating chamber 1, and intake grill communicates with induced draft fan 3 exhaust outlets.Induced draft fan 3 is replaced by extraction pump.
The utility model has the advantages that: owing to be provided with extractor fan, during use, the suction pipe intake grill of extractor fan is communicated with the liquid phase mouth of interior tank body, during work, induced draft fan is extracted the cool air in the interior tank body out, makes the hot air in the heating chamber be able to enter in the interior tank body from the gas phase pipe of interior tank body, internally tank body heating, after work a period of time,, can return heating chamber by air outlet tube and utilize once more owing to some hot air the cool air of extracting out from the liquid phase mouth.Thereby this device externally tank body and interior tank body heat simultaneously, thereby improved the effect that extraction pump vacuumizes effectively.Effectively utilize simultaneously the hot air of heating chamber, save the energy.
Description of drawings
Accompanying drawing 1 is the utility model structural representation.
Embodiment
Open air draught pore and air-out pore on existing heating chamber, suction pipe one end is stretched into indoor, link to each other by loose joint with the liquid phase mouth of interior tank body when being used for work, the suction pipe exhaust outlet communicates with the intake grill of induced draft fan or extraction pump; The exhaust outlet of air outlet tube communicates with heating chamber by the air-out pore, and its intake grill communicates with the induced draft fan exhaust outlet.
Claims (3)
1, the heating equipment of efficiently bleeding in the cryogenic liquide jar interlayer vacuum, comprise heating chamber (1), it is characterized in that it also has suction pipe (2), induced draft fan (3), the intake grill of suction pipe (2) is positioned at heating chamber (1), and exhaust outlet communicates with the intake grill of induced draft fan (3).
2, the heating equipment of efficiently bleeding in the cryogenic liquide jar interlayer vacuum according to claim 1 is characterized in that it also has air outlet tube (4), and the exhaust outlet of air outlet tube (4) communicates with heating chamber (1), and intake grill communicates with induced draft fan (3) exhaust outlet.
3, the heating equipment of efficiently bleeding in the cryogenic liquide jar interlayer vacuum according to claim 1 and 2 is characterized in that induced draft fan (3) is replaced by extraction pump.
