Description

Liquid sample filling device

Technical Field

The utility model belongs to the technical field of the experimental technique of oxidizing liquid and specifically relates to a liquid fills appearance device.

Background

The TDG regulation of the United nations requires that the oxidative liquid test requires that test liquid and dry cellulose are mixed according to the weight ratio of 1:1, the mixture is placed into a pressure container for heating, the pressure rise rate is determined, and the pressure rise rates of the test liquid mixture and the reference substance mixture are compared for oxidative classification. The existing liquid oxidability testing device is lack of a sample loading device, and a small medicine spoon is only used for adding a small amount of mixture into a pressure container for multiple times in the sample loading process and slightly beating the mixture, so that the mixture is ensured to be in good contact with the periphery of an ignition coil and is tightly and firmly loaded. The sample loading process for the whole test has three problems, namely, the time from the beginning of mixing to the heating of the mixture is controlled to be about 10 minutes because the sample loading process is complicated, and the actual operation often exceeds the time requirement. Secondly, the filling compactness is only a small amount of times and is gently flapped without definite quantification, and the compactness of the filled sample directly influences the experimental result. Thirdly, a pressure small hole is formed in the pressure container, and a sample passes through the small hole in the filling process and easily enters the small hole to cause blockage, so that the work of the pressure sensor is influenced, and the experimental result is inaccurate.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a kind device is filled out to the weak point among the prior art to liquid.

Realize the utility model discloses the technical scheme of purpose is: a liquid sample filling device comprises a cylinder body and a push rod; the bottom of the cylinder is open; the push rod extends into the inner cavity of the cylinder body from the top of the cylinder body along the axial direction of the cylinder body; the bottom of the push rod is provided with a push sheet; the push sheet is connected with the inner wall of the cylinder body in a sealing way; the push rod is marked with scale marks along the length direction.

The barrel, the push rod and the push sheet are made of polypropylene PP.

An annular blocking table is arranged on the outer wall of the barrel along the circumferential direction.

The top end of the push rod is provided with a limiting boss for preventing the push rod from completely extending into the barrel.

The position of the scale mark at the joint of the push rod and the push sheet is 0.

And a paint with color is adopted between two adjacent scales of the scale marks to mark blocks.

The cylinder is cylindrical.

By adopting the technical scheme, the utility model discloses following beneficial effect has: (1) the utility model discloses a push rod with scale mark packs, can once only load all samples, has deducted the repeated repetitious of manual operation, and simple and convenient dress appearance process shortens the time, ensures to accomplish in 10 minutes, and secondly the sample injector itself has the pressure scale, adopts quantization pressure value, replaces artificial manual gently to pat, can guarantee that the pressure of dress appearance at every turn is the same, and the tight real degree of assurance loading is the same.

(2) The utility model discloses set up the annular on the outer wall of barrel and kept off the platform, guaranteed the distance of stretching into of injector to can cover the pressure aperture, thereby effectively avoid the aperture to block up.

(3) The utility model discloses set up spacing boss, can prevent that the push rod from falling into in the barrel.

(4) The utility model discloses a scale mark is "0" in the position of the junction of push rod and ejector pad, the reading of being convenient for.

(5) The utility model discloses an adopt the coating mark blocking that has the colour between two adjacent scales of scale mark, the reading of further being convenient for.

(6) The utility model discloses a barrel is the column, and not only the processing of being convenient for makes things convenient for the sample injector to stretch into pressure vessel moreover.

Drawings

In order that the present invention may be more readily and clearly understood, the following detailed description of the present invention is given in conjunction with the accompanying drawings, in which

Fig. 1 is a schematic structural diagram of the present invention.

The reference numbers in the drawings are:

the device comprises a cylinder body 1, a push rod 2, scale marks 2-1, a limiting boss 2-2 and a push sheet 3.

Detailed Description

(example 1)

Referring to fig. 1, the liquid sample filling device of the present embodiment includes a cylinder 1 and a push rod 2.

The cylinder 1 is cylindrical and is open at the bottom. The push rod 2 extends into the inner cavity of the cylinder body 1 from the top center of the cylinder body 1 along the axial direction of the cylinder body 1. The bottom of the push rod 2 is provided with a push sheet 3. The push sheet is connected with the inner wall of the cylinder body 1 in a sealing way. The push rod 2 is marked with scale marks 2-1 along the length direction.

Preferably, the barrel 1, the push rod 2 and the push sheet 3 are made of polypropylene PP to improve corrosion resistance and service life.

Furthermore, the outer wall of the barrel body 1 is circumferentially provided with an annular baffle table 1-1 to ensure the extending distance of the sample injector and cover the small pressure hole, thereby effectively avoiding the blockage of the small hole.

Furthermore, the top end of the push rod 2 is provided with a limit boss 2-2 for preventing the push rod 2 from completely extending into the cylinder body 1, so that the push rod is prevented from completely extending out of the cylinder body 1.

Further, the position of the scale mark 2-1 at the joint of the push rod 2 and the push sheet is 0, so that better reading can be carried out.

Furthermore, two adjacent scales of the scale marks 2-1 are marked into blocks by adopting colored paint, so that the scores can be more visually seen.

4. keeping the bottom opening of the cylinder body 1 in an upward state, and pushing the push rod 2 to slowly push the substance to be tested into the test pressure container;

5. the cylinder body 1 and the test pressure container are turned upside down together, and the bottom opening of the cylinder body 1 faces downwards;

6. pushing the push rod 2, further compacting the substance to be measured, and recording the scale value on the push rod 2 at the moment;

7. and slowly taking down the barrel body 1, and finishing sample loading.

The above-mentioned embodiments, further detailed description of the objects, technical solutions and advantages of the present invention, it should be understood that the above-mentioned embodiments are only specific embodiments of the present invention, and are not intended to limit the present invention, and any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the scope of the present invention.
