Abstract
The invention relates to an apparatus for drawing samples from material containing solid particles, which material is in a flowing motion. In the apparatus, the sampling member (3, 13, 24) is connected to an adjusting device (4, 15, 26) and a suction member (6, 17, 25) so that the material flow coming from the sampling member (3, 13, 24) by means of the adjusting device (4, 15, 26) can be directed via the suction member (6, 17, 25) to form the sample.
Claims9
An apparatus for drawing a sample from a flow of slurry material, comprising:
- a sampling member defining a passage having a first end and a second end, the sampling member being adapted to be place with the first and second ends of the passage both in direct open communication with the flow of slurry and the first end upstream of the second end,
- a flow control device having a first state in which it permits flow of slurry through the passage and a second state in which it prevents such flow, and
- suction means coupled to the passage defined by the sampling member at a location between the flow control device and the first end of the passage, for extracting slurry material from the passage when the flow control device is in its second state.
An apparatus for conducting a slurry material from a first location to a second location, comprising:
- a duct through which the slurry material flows from the first location to the second location,
- a sampling member defining a passage having a first end and a second end, the first and second ends of the passage being in direct open communication with the interior space of the duct at locations spaced apart along the duct, whereby slurry material flowing from the first location to the second location may enter the passage at the first end thereof and leave the passage at the second end thereof,
- a flow control device located inside the duct and having a first condition in which it permits flow of slurry material through the passage and a second condition in which it prevents flow of slurry material through the passage,
- a sampling conduit connected to the sampling member at a location between the flow control device and the first end of the sampling member, and
- suction means connected to the sampling conduit for drawing slurry material from the passage.
