Abstract
The utility model relates to a chromatographic column box of a double-side opening door, which comprises a door shaft, a ventilating door, a partition board, heating wires, a chromatographic column frame, a blade, a motor and a chromatographic column box door, wherein a chromatographic column frame is arranged in the chromatographic column box door, the partition board is arranged behind the chromatographic column frame, the heating wires are arranged on the back side of the partition board and the blade is arranged between the heating wire and is connected with the motor arranged behind a box body. The utility model is characterized in that the ventilating door is a double-side opening door, and is arranged on the side face of the chromatographic column box of a double-side opening door through the door shaft. The utility model has the advantages that the utility model reduces the effective area of the back of the chromatographic column box of a double-side opening door without happening the interference of the door and the motor, and can ensure the air convection in the chromatographic column box of a double-side opening door so as to achieve the goal of uniform temperature in the chromatographic column box of a double-side opening door.
Description
Technical field
The utility model relates to the chromatograph box that a kind of bilateral opens the door, relate in particular to a kind of being used in the petroleum prospecting process, analyze in pyrolysis gas chromatography (Pyro-GC) (analysis) instrument of the sample that extracts, can control the chromatograph box of the cooling draught of chromatograph box, belong to technical field of analytical instruments.
Background technology
Widely used pyrolysis gas chromatography (Pyro-GC) (analysis) instrument in the petroleum prospecting process at present, its chromatograph box is to reach the temperature field in the even case and cool off two purposes of the temperature inside the box fast, often settle blade motor 7 and air door 1 at chromatograph box back, to satisfy above-mentioned requirements, as shown in Figure 1, owing to lay blade motor 7 and air door 1 simultaneously at chromatograph box back, strengthened the back area of chromatograph box, thereby increased the volume of chromatograph box, reduced heating rate (identical heating power), and having when opening the door motor to interfere, action is inconvenient.Moreover, when need cool off chromatograph box, a fan turnover air door only is provided after, the air flow in chromatograph box is very chaotic, has influenced cooling effect.
Summary of the invention
Be that invention is a kind of the door and the interference of motor can not take place the purpose of this utility model, reduced the useful area of chromatograph box back, and can guarantee the cross-ventilation in the chromatograph box, reach the chromatograph box that the temperature inside the box bilateral even and quick cooling purpose opens the door.
For realizing above purpose, the technical solution of the utility model provides the chromatograph box that a kind of bilateral opens the door, comprise door-hinge, air door, dividing plate, heater strip, chromatogram pylon, fan blade, motor, chromatographic column chamber door, chromatographic column is set up in the chromatographic column chamber door, dividing plate is located at chromatogram pylon back, heater strip is located at membrane backside, between heater strip, be provided with fan blade, fan blade is connected with the motor of being located at the casing back, it is characterized in that, described air door is a double door, is located at the side of chromatograph box by door-hinge.
Described air door is by going out air door and shutter is formed.
The utility model is the method for designing that has changed original chromatograph box back pullout (BPO), employing is opened the door in the side of chromatograph box, like this, because the fan blade motor is placed two different planes with the cooling door, the door and the interference of motor can not take place, reduce the useful area of chromatograph box back, also promptly reduced the volume of chromatograph box, improved heating rate (equal-wattage).And use two methods for designing of fanning door, and when at closing time, can guarantee the cross-ventilation in the chromatograph box, reach the uniform purpose of the temperature inside the box; When opening the door, because two fan doors are respectively shutter and go out the air door effect of the interior fan blade of case in addition, make the air flow in the case smooth and easy, it is rapider to lower the temperature.
The utility model has the advantages that the door and the interference of motor can not take place, reduced the useful area of chromatograph box back, and can guarantee the cross-ventilation in the chromatograph box, reach the temperature inside the box evenly and cool off fast purpose.
Description of drawings
Fig. 1 is former chromatograph box structural representation;
The chromatograph box structural representation that Fig. 2 opens the door for a kind of bilateral.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Embodiment
As shown in Figure 2, the chromatograph box structural representation that opens the door for a kind of bilateral, the chromatograph box that described a kind of bilateral opens the door is by door-hinge 1, air door 2, dividing plate 3, heater strip 4, chromatogram pylon 5, fan blade 6, motor 7, chromatographic column chamber door 8 is formed, chromatogram pylon 5 is installed in 8 li of chromatographic column chamber doors, dividing plate 3 is installed in chromatogram pylon 5 back, heater strip 4 is installed in dividing plate 3 rear sides, between heater strip 4, be provided with fan blade 6, fan blade 6 is connected with the motor 7 of being located at the casing back, described air door 2 is a double door, by going out air door 9 and shutter 10 is formed, be installed in the side of chromatograph box by door-hinge 1.
During work, with 90 ° of door-hinge 1 swings, close out air door 9 and shutter 10 clockwise, starter motor 7, rotating blading 6 is opened heater strip 4 heating, be warming up to setting value, because the turnover air door 9,10 of chromatograph box is in closed condition, the fan blade 6 of this moment is used as stirring.Air passes heater strip 4 under fan blade 6 effects, flow into the chromatogram column compartment from the gap between dividing plate 3 and the chromatograph box inwall, hot-air blows to the chromatographic column that is placed on the chromatogram pylon 5 equably, make the chromatographic column heating, last, hot-air flows into fan blade 6 air inlets from the middle part ventilating opening of dividing plate 3.Make the temperature inside the box even.
Behind end-of-job, stop heater strip 4 heating, with 90 ° of door-hinge 1 swings, make shutter 10, go out air door 9 unlatchings counterclockwise, the fan blade 6 of this moment is used as cooling, air is under fan blade 6 effects, cold air flows into from air inlet 10, passes the chromatographic column that is placed on the chromatogram pylon 5, and the middle part ventilating opening by dividing plate 3 flows into fan blade 6 air inlets again, blow to heater strip 4 backs by fan blade 6 and discharge, make cooling in the case from air outlet 9.The utility model uses the method for designing of two fan doors, when at closing time, can guarantee the cross-ventilation in the chromatograph box, reaches the uniform purpose of the temperature inside the box; When opening the door, because two fan doors are respectively shutter and go out the air door effect of the interior fan blade of case in addition, make the air flow in the case smooth and easy, it is rapider to lower the temperature.
