Abstract

The utility model discloses a portable food packaging specific migration test instrument which comprises a stainless steel sample cell, a liquid adding port is arranged on the sample cell and sealed by using a screw, the sample cell consists of an upper part with a cavity and a lower part with the cavity, the upper and the lower parts are connected by a pressurization mechanism for forming a sealed cavity, the test instrument further comprises a housing and a control circuit board positioned in the housing, a heating device and a temperature sensor are arranged on the sample cell, and the sample cell is positioned on a sample cell bracket in the housing and not contacted with the housing directly. The portable food packaging specific migration test instrument solves the defect of inconvenient movement by increasing the heating element on the sample cell and simultaneously integrates data setting and display on the housing of the instrument, thereby leading the operation and the use to be more convenient, leading the size to be smaller and facilitating the carry; the test instrument is not only applicable to ordinary laboratory detection, but also applicable to field detection, mobile laboratory detection and the like, thereby being very conductive to field supervision of administrative organizations and self-detection of enterprise products.

Description

Portable food packing specific transfer test instrument

Technical field

The utility model relates to a kind of portable food packing specific transfer test instrument.

Background technology

At present, the general adopting soaking method of domestic food packing detection range detects, and article to be checked are placed particular solution, moves experiment, and the testing conditions instability influences testing result.The external stainless steel sample cell that uses, then sample cell is put into baking oven and begun the migration experiment, its shortcoming is: owing to used baking oven, large power supply, large tracts of land experiment place must be arranged, can't be used for on-the-spot the detection and mobile laboratory's detection, external A type sample cell is in order to increase bearing capacity etc., design loaded down with trivial details, problems such as leakage often appear in operation inconvenience, and mechanical processing technique complexity.

The utility model content

The utility model technical issues that need to address provide and a kind ofly are convenient for carrying, are not affected by the external environment, the portable food packing specific transfer test instrument that be suitable for on-the-spotly detecting, the mobile laboratory is detected.

For addressing the above problem, technical solution adopted in the utility model is: a kind of portable food packing specific transfer test instrument, comprise the stainless steel sample cell, described sample cell is provided with filling opening and seals with screw, sample cell is made of the two parts up and down with cavity, by pressing mechanism two parts connection up and down, form the cavity of sealing, this test instrument also comprises shell, be positioned at the control circuit board of housing, also be provided with heater element on the described sample cell, temperature sensor, this sample cell is positioned on the sample cell carriage of housing, does not directly contact with shell.

Described sample cell the latter half is provided with groove and threaded hole, threaded hole and groove location are with sample cell center symmetry, by threaded hole and groove fixed frame posture connecting rod pressing mechanism, on connecting rod pressing mechanism upside connecting rod, be provided with forcing screw, the right side connecting rod is provided with trip bolt.

Described sample cell cross section is circular.

Described heater element can be any one in Elema heating rod, Si-Mo rod heating rod, nickel filament heater strip, the Fe-Cr-Al wire heating element.

Described shell is provided with display screen that is used for video data and the keyboard that is used for setting data.

Described control circuit board core is a microprocessor, has temperature sensing circuit, display circuit, keyboard to set up circuit, heating components and parts control circuit.

Adopt the beneficial effect that technique scheme produced to be: basis is novel to solve the shortcoming that it is inconvenient to move by increase heating element on sample cell, simultaneously data setting and demonstration are integrated on the tool housing, it is convenient that it is manipulated, can do volume very little, be easy to carry, it is strong that this novel sample cell has a bearing capacity, good airproof performance, use simple to operate, the processing and manufacturing characteristic of simple; This portable food packing specific transfer test instrument model is " a FCM-A1 type ", this test instrument is not only applicable to common lab and detects, also be suitable for on-the-spot detection, mobile laboratory's detection etc., very help on-the-spot supervision of administrative organization and enterprise product self check, China's food security is significant.

Embodiment

Below in conjunction with accompanying drawing the utility model is done and to be described in further detail:

As shown in Figure 1, 2, 3, this novel shell 1 that comprises, be positioned at the sample cell 5 and the control circuit board 7 of shell 1, on shell 1, be provided with display screen 2, be used for displays temperature, time and data etc. when parameter is set, on shell 1, also be provided with keyboard 3, be used for data such as design temperature, time, be provided with power switch etc. in addition.

Control circuit board 7 is positioned at enclosure, comprises circuit such as temperature sensing circuit, display circuit, keyboard to set up circuit, heating components and parts control circuit, timing circuit, and its control core adopts microprocessor, and the control accuracy height is easy to operate, powerful.

Sample cell 5 is placed on the sample cell carriage 8 in the shell 1, directly do not contact with shell 1, reduced the thermal losses of sample cell, make temperature stability good, have more energy-saving effect, sample cell 5 has up and down, and two parts constitute, top 10 has the cylindrical shape of groove, be to have liquid filling hole 13 on the relative one side of groove, screw 4 is installed on liquid filling hole, and seal by O-ring seal, heating components and parts 18 are housed in the side, these heating components and parts 18 can be the Elema heating rods, the Si-Mo rod heating rod, the nickel filament heater strip, in the Fe-Cr-Al wire heating element any one, the side also is equipped with temperature sensor 19 simultaneously, temperature sensor 19 is an angle of 90 degrees with heating components and parts 18, lower part 14 is similarly the cylindrical shape with groove, be respectively equipped with a threaded hole 17 in side bottom with the center symmetry, a groove 20, be used for fixing frame-type connecting rod 6 pressing mechanisms, and prevent to collapse out when sample cell from pressurizeing, frame-type connecting rod 6 pressing mechanisms two parts up and down connect, constitute the user mode of sample cell 5, be equipped with a grommet type seals 12 in the two-part groove about the sample cell 5, the groove of two parts up and down of sample cell 5 relatively and O-ring seal form the sealed cavity 16 of sealing jointly, in sealed cavity 16, place for test sample 15, frame-type connecting rod 6 pressing mechanisms comprise forcing screw 9, three connecting rods, a connecting rod wherein by screw retention on threaded hole 17, have threaded hole on the connecting rod, forcing screw 9 is installed, be used for also having one one end to have crotch, have threaded hole on it sample cell 5 pressurizations, crotch is hooked in the groove 20, and threaded hole trip bolt 11 holds out against sample cell 5.
