Technical field
This utility model relates to experimental apparatus technical field, is specifically related to a kind of automatic acid adder of soil digestion.
Background technology
In chemical analysis, it is often necessary to by round bottom test tube digest and decompose soil-like by the way of heating, it is longer that round bottom test tube has body, sample is difficult to boil and spatters mistake, cross-sectional area is little and makes acid contact fully with sample, less by acid amount, advantage that the efficiency of Specimen eliminating is higher etc., in heating process, it sometimes appear that add subacidity to cause test failure, so needing a set of liquid supply device, when deficiency is added in acid, when being not enough to clear up, the most automatically add acid solution.
Utility model content
The purpose of this utility model is to overcome deficiency of the prior art, it is provided that a kind of automatic acid adder of soil digestion, bright achieves automatic liquid supply, improves test efficiency.
For solving above-mentioned technical problem, the technical solution of the utility model is:
A kind of automatic acid adder of soil digestion, including control chamber, it is supported in the furnace shell above control chamber, the heater being fixed in furnace shell and fluid infusion unit, the graphite body of heater that described heater includes heating plate, is supported in heating plate, described graphite body of heater is provided with some clears up hole, it is filled with heat preserving and insulating material between described furnace shell and heater, described furnace shell is equipped with observation window with clearing up hole correspondence position front-back, and described fluid infusion unit includes: an annex solution deposit box, a pipette, a dosing pump, a liquid pushing tube, a sensor and an on and off switch；Described annex solution deposit box, pipette, dosing pump and liquid pushing tube sequentially connect, and clear up the test tube in hole described in the other end connection of described liquid pushing tube, and described on and off switch is electrically connected with described metering
Pump and described sensor；Described sensor is cleared up on hole described in being assemblied in, and the test tube solution information being used for clearing up in hole described in transmitting is to described on and off switch.
Preferably, described furnace shell is supported on control chamber by more than three instlated tubulars.
Preferably, it is provided with heat dissipation metal plate between described furnace shell and control chamber.
Preferably, described heating plate is provided with temperature sensor.
Preferably, described sensor is printing opacity sensor.
Compared with prior art, the beneficial effects of the utility model are: this utility model simple in construction, save and use manpower；Improve test efficiency, also ensure that test mass.

Detailed description of the invention
By making, architectural feature of the present utility model and effect of being reached are had a better understanding and awareness, coordinate detailed description in order to preferred embodiment and accompanying drawing, be described as follows:
A kind of automatic acid adder of soil digestion, including control chamber 1, is supported in the furnace shell 2 above control chamber 1, the heater being fixed in furnace shell 2 and fluid infusion unit.
The graphite body of heater 3 that described heater includes heating plate 14, is supported in heating plate 14, described graphite body of heater 3 is provided with some clears up hole 4, it is filled with heat preserving and insulating material between described furnace shell 2 and heater, described furnace shell 2 is equipped with observation window with clearing up hole 4 correspondence position front-back, can intuitively observe the Specimen eliminating situation in test tube, it is to avoid example reaction is excessively or the phenomenon that is evaporated.
Described fluid infusion unit includes: annex solution deposit box 5, pipette 6, dosing pump 7, liquid pushing tube 8, sensor 9 and an on and off switch 10；Described annex solution deposit box 5, pipette 6, dosing pump 7 and liquid pushing tube 8 sequentially connect, and clear up the test tube in hole 4 described in the other end connection of described liquid pushing tube 8, and described on and off switch 10 is electrically connected with described dosing pump 7 and described sensor 9；Described sensor is printing opacity sensor, described sensor 9 be assemblied in described in clear up on hole 4, the test tube solution information clearing up in hole 4 described in transmit gives described on and off switch 10.
Described furnace shell 2 is supported on control chamber 1 by more than three instlated tubulars 11, is provided with heat dissipation metal plate 12 between described furnace shell 2 and control chamber 1.Furnace shell 2 separates with control chamber 1, and between be provided with heat dissipation metal plate 12, the temperature of such furnace shell 2 does not interferes with control chamber 11, and the controller inside control chamber 1 can work at normal temperatures.
Described heating plate 14 is provided with temperature sensor 13.
During use, plugging in, heating plate 14 produces heat and passes to graphite body of heater 3 to add dissipation of heat hole, owing to graphite body of heater 3 is wrapped in dissipation hole, so can heat the test tube in dissipation hole with well-proportioned, being filled with heat preserving and insulating material in furnace shell 2, heat utilization rate is high.
Printing opacity sensor 9 detects when acid is added not enough, sends information on and off switch 10, and on and off switch 10 opens dosing pump 7, according to setting content such as flow, flow velocity, carries out the interpolation of acid solution.
