Detailed Description

The present invention will be described in detail below, and it is apparent that the technical solutions in the embodiments of the present invention are described clearly and completely. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The utility model discloses an improve and provide a powder material transfer tube here, the technical scheme of the utility model is:

as shown in fig. 1 to 4, a powder material transfer tube includes a transfer tube body 1, and further includes:

the powder sample placing bin 3 is arranged on the inner wall of the end part of the transfer pipe body 1, and when the powder sample placing bin 3 is used, the powder sample is placed in the powder sample placing bin 3 at the end part of the transfer pipe body 1;

the fixed block 5 is fixedly arranged on the inner wall of the transfer pipe body 1, the inner wall of the fixed block 5 is provided with an inclined air supply hole 51, and as shown in the figure, the transfer pipe body 1 needs to be kept in a state as shown in the figure during transfer, so that the air supply hole 51 is aligned to a position where powder wall hanging possibly occurs, and the wall hanging powder can be conveniently and quickly washed, sprayed and cleaned;

the inner wall of the transfer pipe body 1 is also provided with an air supply mechanism, and the inner wall of the transfer pipe body 1 is inserted with a temporary choke valve 4.

Further, the air supply mechanism comprises a push rod 2, a piston 21 and a push plate 22, wherein the piston 21 and the push plate 22 are respectively and fixedly arranged at two ends of the push rod 2.

Further, the piston 21 is made of rubber, the piston 21 is connected to the inner wall of the transfer pipe body 1 in a sliding mode, the piston 21 can adopt the same design for a syringe, and the effect of pushing air is achieved.

Further, the jack has been seted up to the outer wall of transfer pipe body 1, and interim choke valve 4 slides and pegs graft in the inner wall of jack, and interim choke valve 4 same outer wall can set up to rubber material for interim choke valve 4 can keep inserting the different degree of depth positions department of jack.

The specific use steps are as follows: firstly, the temporary choke valve 4 is drawn out, then the push rod 2 and the piston 21 are pulled backwards through the push plate 22, the effect of drawing the piston 21 outwards for a certain distance is achieved, then the temporary choke valve 4 is inserted into the insertion hole again, the air supply hole 51 is blocked, and a certain amount of air is stored between the temporary choke valves 4 at one end of the piston 21;

then putting the powder sample to be transferred into the sample powder sample placing bin 3 by a tool, transferring the powder sample into a container required by the test through the transfer pipe body 1, then drawing out part of the temporary air choke valve 4 (at this time, the temporary air choke valve 4 is only required to remove the blocking to the tail end of the air supply hole 51, and the temporary air choke valve cannot be completely drawn out), rapidly pushing the piston 21 forward through the push rod 2 and the push plate 22 to enable air to rapidly pass through the air supply hole 51, sending a small amount of powder left in the transfer pipe body 1 into the required container by accelerated gas flow, avoiding the occurrence of the situation that the powder is left and hung on the inner wall of the transfer pipe body 1, reducing the loss of the powder in the transfer, and ensuring the reliability of the test result for the experiment needing to accurately control the amount by the mode;

and the operation of this mode is simple and convenient, can promote the availability factor, shifts pipe body 1 simultaneously and can utilize the injection tube to cut the support, and required instrument parts etc. easily make can use widely on a large scale.
