Description

The invention relates to sampling devices, B particular k devices for pulp sampling, and can be used in the mining and chemical industries,

The purpose of the invention is to increase the representativeness of the sample and the expanded functionality of the sampler.

FIG. 1 shows the sampler, a general view; FIG. 2, section A-A in FIG. one; in fig. 3 is a view B in FIG. one.

The pulp sampler includes a housing 1 connected to the slurry pipeline 2, a blade two-shaft: mixing mixer 3, a flow distributor made in the form of a tank 4 having an inlet 5, two drain holes 6 for draining the sample back to the slurry pipeline 2 and the chute 7 with guides 8 for supplying the sample to the maximum sampling body 9. The sampling body 9 is made in the form of a sector 10 with a spruce 11 and a hollow shaft 12, under which the pulp receiver 13 is located. The receiving slit 11 is made so with respect to the axis of symmetry of the sector 10. One of the shafts of the mixer 3 is equipped with a gear 14, and the other with a friction gear 15. Between them, both the shafts of the mixer 3 are connected by a V-belt gear 16, and the belt drive 17 connects the Sampling Body 9 s an idler pulley 18 mounted on a movable lever 19, which is driven by a pneumatic device 20.

The sampler works as follows

The pulp flow results in the vane of the mixer blade 3 and, mixing, is divided into two parts. Most of the flow is returned to the slurry pipeline 2, mine sampling body 9, through the drain holes 6. A smaller part of the flow along chute 7 with guides 8 comes to the sampling body 9. Mixing the flow before sampling and passing it through guides 8 under laminar flow conditions makes the sample representative. At the outlet of the sampling unit 9, both streams are connected 11279732

with in the slurry pipe 2 again. When friction gear 5 is engaged, the torque, taken from the two shafts of the mixer, is transmitted through

5 belt drive 7 to the hollow shaft 12 of the sampling body 9. The hollow shaft 12 rotates the sector 10 with the sampling slot And periodically substituted it for receiving

 iO samples. The sample through the hollow shaft 12 enters the receiver 13. When the friction transmission is disconnected, sector 10 is caused by the unequal drag resistance of the NIN to the counter flow occurring on the surfaces. around the slit 1, the 15 turns and stops at a position where the sample cannot enter the slit.

20 Supplying the sampler with the pulp flow distributor will allow it to be included in high-capacity pulp flows. This is achieved in that part of the stream passes

25 The sampling organ and the slit itself is on the lateral surface of the sector, therefore it has less resistance to the flow of pulp, the flow of the entire flow through the free area

30, but the impeller impeller of the kneader makes it homogeneous, as the flow heterogeneity is reduced due to wall effects.
