Description
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.

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.
