Detailed Description
The utility model will be further described with reference to the drawings and detailed description.
In the first embodiment, referring to fig. 1, the powder sampling apparatus of the present utility model includes a sampling tube, a sampling bottle 2; the sampling tube comprises a first sampling tube section 1-1 and a second sampling tube section 1-2 which are communicated with each other, wherein the head end of the first sampling tube section 1-1 and the tail end of the second sampling tube section 1-2 are both closed, the first sampling tube section 1-1 is horizontally arranged, and the second sampling tube section 1-2 is horizontally arranged; the bottle mouth 3 of the sampling bottle 2 is provided with external threads, the bottom of the first sampling tube section 1-1 is provided with an internal threaded hole, the top of the bottle mouth 3 is in threaded connection with the internal threaded hole, the top of the first sampling tube section 1-1 is provided with a pressure difference balancing port 6, and the outer wall of the tail end of the first sampling tube section 1-1 is sleeved with a rubber ring 5; the top of the second sampling pipe section 1-2 is uniformly provided with a plurality of receiving windows 4 along the axis direction. The head end and the tail end are respectively one end far away from a sampled pipeline/tank body when in use; the sampling tube is made of plastic, so that magnetic anisotropy is avoided; the number of the receiving windows 4 is set according to the requirement, and three receiving windows are provided in the first embodiment.
In the first embodiment, referring to fig. 2, the powder sampling apparatus of the present utility model is used for sampling powder in the main pipe 9; the lateral wall intercommunication of trunk line 9 has the sample to be in charge of 7, the sample is in charge of 7 keep away from the one end of trunk line 9 is provided with sampling window 8, be in on the trunk line 9 the sample is in charge of 7 both sides all are provided with knife valve 10, during the sample tail end of second sample pipe section 1-2 passes in proper order sampling window 8, sample are in charge of 7 back stretch into in the trunk line 9, the lateral wall Zhou Xiangding of rubber ring 5 leans on the inside wall circumference of sample is in charge of 7.
When powder in the main pipeline 9 needs to be sampled, under the mode of a sampling spoon, the lower knife valve 10 is closed, the upper knife valve 10 is kept in an open state for about 5 minutes, then the upper knife valve 10 is closed, sampling operation is started, the sampling window 8 is opened, a plastic sampling spoon is inserted into the main pipeline 9 from the sampling window 8 through the sampling branch pipe 7, a powder sample is extracted by the spoon and then poured into a sampling bag, the sampling is repeatedly performed, the sampling window 8 is closed after enough sample is taken, the lower knife valve 10 is opened, and finally the upper knife valve 10 is opened, so that the sampling operation is completed.
