to samplings of beans, corns, feeds;
b) total length is 50cm, slot length is 40cm, slot width is 0.8cm ~ 1.5cm, outer
diameter is 1.6cm ~ 2.0cm, tip is about 4.0cm, solid cone; it is applicable
to samplings of small, medium grains, oilseeds, feeds;
c) total length is 55cm, slot length is about 35cm, slot width is 0.6cm ~ 0.7cm,
the maximum outer diameter is about 1cm, head-tip-shaped; it is
applicable to sampling of powder cargo.
5.2 Double-sleeve sampler and slot receiver
Applicable to sampling of bulk static cargo.
According to the actual loading transport tools, the size of the cargo, the storage
of cargo, use double sleeve sampler of different specifications, length. The
commonly used one. total length is 110cm, handle length is 15cm, cone length
is 6.5cm, outer diameter of outer tube is 2.6cm, inner diameter is 2.0cm, with
four outlets with each outlet of 20cm×1.8cm. There are also other double-sleeve
standard samplers with total lengths of 250cm, 300cm, etc.
The slot receiver is made of tin or aluminum skin, of which the length is 100cm,
semi-cylindrical, opening width is 10cm, used to collect the sample collected by
double-sleeve sampler. Or it can use canvas of sufficient length to collect the
sample.
5.3 Sampling shovel
The shovel length is about 13cm, the width is about 8cm, the side height is
about 4cm, the handle length is about 8cm. See Figure A.1 of Annex A.
5.4 Automatic mechanical sampling device
Applicable to dynamic cargo sampling. The device mainly consists of four parts.
a) shunt mechanical sampler;
b) rotary divider;
c) gravity divider;
d) rotary-table sampler.
The specific operation is carried out according to the specifications of each
sampling device.
5.5 Deep-layer sampler
A semi-automatic sampling device that mainly consists of several connectable
cylinder. A momentary pause between the opening of the inlet and outlet valves
is to ensure that the sample first enters the bottom of the cylinder and causes
a slight increase in the internal pressure of the cylinder to prevent the sample
from entering the top when the top valve is opened.
5.12 Simple counterweight sampling tank
The simple counterweight sampling tank (see Figure A.3) is suitable for
sampling at different depths in a variety of storage tank. It consists of a stainless
steel cylinder (capacity of approximately 500mL), a counterweight with a
separate bottom and a tapered barrel neck. The metal ring fixed on both sides
of the cone neck has a ring at its highest point. The rope passes through the
ring and is tied to the cork of the conical barrel neck. Empty sampling tank with
cork drops to the specified depth of liquid grease. Urgently pull the rope and
unplug the cork, the tank shall be full of samples.
5.13 Sampling barrel with bottom valve
The sampling barrel with foot valve (see Figure A.4) is suitable for taking
samples from liquid oil contained in tanks or oil tanks. It is divided into two parts.
the upper and the lower. The top of the upper is open. The lower part is
equipped with a heavier screw mechanism on the outside of the barrel. A
lightweight self-weight valve is fixed at the bottom to ensure the stability of the
sampling device from bottom to top. When the sampling barrel falls in the liquid
grease, the pressure of the oil on the valve keeps the bottom open until the
grease flows evenly into the barrel. When it stops falling, the bottom valve
closes and the grease is drawn from the depth of the sampling barrel.
5.14 Tube sampler
Applicable to sampling of paste grease. (See Figure A.5). It is a stainless steel
device consisting of two concentric tubes of the same length and close together,
one of which can rotate in the other tube. Each tube has a longitudinal opening.
In a certain position, the tube is opened so that the oil flows in, and the tube is
closed by turning the inner tube.
5.15 Sampling probe
Sampling probe (see Figure A.6) is used for stearin sampling. It is made of
stainless steel, with semi-circular or C-shaped cross section. When it is twisted
and inserted into grease, it shall obtain a sample of oil.
5.16 Sampling tube
Made of thick-walled glass tube or stainless steel, suitable for liquid grease
sampling (see Figure A.7).
the cabin. After extracting the first batch of samples, a small batch of
samples shall be increased after every 1000t of loading and unloading.
When it is less than 10......
