Summary of the invention
The purpose of this utility model is the defect for above-mentioned prior art and deficiency, there is provided one can realize overall process for people automatically to monitor, multichannel concordance, it is ensured that the accuracy of experimental result and the Intelligent heating backflow digestion instrument of effectiveness are tested for water chemical oxygen demand.
For achieving the above object, technical solution adopted in the utility model is: instrument is cleared up in the backflow of this Intelligent heating, including conical flask and condensing tube, also include support, be provided with heating chamber in the lower section of support, described heating intracavity is provided with multiple heater, covers equipped with black crystal panel on the heaters, being provided with the multiple Zhi Bei districts corresponding with heater in described black crystal panel, described conical flask is placed in Zhi Bei district;
Described support is provided above cooling chamber, and described condensing tube is arranged in cooling chamber, and its lower end is connected with corresponding conical flask bottleneck;
Also include the panel being connected with heater, controlled heating-up temperature and the heat time heating time of each heater by panel respectively.
The back side of cooling chamber is provided with cooling fan, and the sidewall at cooling chamber offers louvre.
It is provided with the cooling water cover of cladding condensing tube in described cooling chamber, in cooling water cover, is marked with cooling water.
The upper end of described condensing tube is provided with backflow cup, and the diameter of backflow cup is more than condensing tube.
Described Zhi Bei district and heater are provided with 8, in the upper and lower corresponding of black crystal panel.
Described heating chamber is coated on frame bottom by cover plate and is formed.
The back side in described heating chamber is provided with radiator fan.
The outer wall of described cooling chamber is embedded with display operating panel, and display operating panel is connected with panel.
This utility model not only heating panel corrosion-resistant easy cleans, and energy multichannel independence constant temperature and independent switch, and each passage process data can be carried out historical record, it is achieved overall process monitors automatically, multichannel concordance, it is ensured that the accuracy of experimental result and effectiveness.

Detailed description of the invention
As shown in Figure 1 and Figure 2, this utility model clears up instrument for a kind of Intelligent heating backflow, and it includes that support 1, conical flask 4 and condensing tube 5, the lower section of described support 1 are provided with heating chamber 2, and described heating chamber 2 is coated on bottom support 1 by cover plate 2.1 and is formed.Multiple heater 8 is installed in described heating chamber 2, in heater 8 overlying equipped with black crystal panel 10, being provided with the multiple Zhi Bei districts corresponding with heater 8 in described black crystal panel 10, described conical flask 4 is placed in Zhi Bei district, and described black crystal panel 10 is the most high temperature resistant to be also convenient for cleaning.In this utility model, described Zhi Bei district and heater 8 are provided with 8, can arbitrarily place 1-8 the conical flask 4 for experiment in the upper and lower corresponding of black crystal panel 10, the most black crystal panel 10, as long as opening the heater 8 of correspondence.Also including the panel being connected with heater 8, controlled heating-up temperature and the heat time heating time of each heater 8 by panel respectively, the outer wall of described cooling chamber 3 is embedded with display operating panel 6, and display operating panel 6 is connected with panel.Therefore this utility model multichannel independence constant temperature and independent switch, and each passage process data can be carried out historical record, it is achieved overall process monitors automatically, multichannel concordance, it is ensured that the accuracy of experimental result and effectiveness.
Described support 1 is provided above cooling chamber 3, and described condensing tube 5 is arranged in cooling chamber 3, and is connected in corresponding conical flask 4 bottleneck.Condensing tube 5 can be lowered the temperature by cooling chamber 3 by air-cooled or water-cooled, makes the steam condensation of rising.Air-cooled can arrange cooling fan at the back side of cooling chamber 3, the sidewall at cooling chamber 3 offers louvre 3.1, is lowered the temperature condensing tube 5 by cold wind.Water-cooled can arrange the cooling water cover of cladding condensing tube 5 in described cooling chamber 3, is marked with cooling water in cooling water cover, and condensing tube 5 can also be lowered the temperature by logical supercooled water.Be provided with backflow cup 7 in the upper end of condensing tube 5, the diameter of backflow cup 7 is more than condensing tube 5, and therefore when ascending air arrives backflow cup 7, reduced velocity flow, the steam that part enters backflow cup 7 by condensing tube 5 condenses backflow under gravity.
The back side in described heating chamber 2 is also provided with radiator fan 11, can dispel the heat with heater 8 and black crystal panel 10 after off-test, and the sidewall at cover plate 2.1 can also offer some air outlets 2.2, it is easier to heat radiation.
This utility model not only heating panel corrosion-resistant easy cleans, and energy multichannel independence constant temperature and independent switch, and each passage process data can be carried out historical record, it is achieved overall process monitors automatically, multichannel concordance, it is ensured that the accuracy of experimental result and effectiveness.
