Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. The examples are given solely for the purpose of illustration and are not intended as limitations on the scope of the invention.
Example 1
Referring to fig. 1, the utility model provides a liquid sampling machine suitable for tank wagon or storage tank includes sampling lifting lever 4 and sampler support 5, sampler support 5 is installed on the sampling platform 8 that has a take the altitude through base 6, base 6 is including being used for along the bearing group of vertical direction fixed mounting sampler support 5, the one end of sampling lifting lever 4 can reciprocate on sampler support 5 under the control of the sampling personnel, thereby be convenient for reciprocating of the sampling hose 3 that control and sampling bottle 7 are connected (the installation of sampling hose 3 on sampling lifting lever 4 adopts the hanging of similar fish tape on the fishing rod to carry fixed mode), and stretch into tank wagon manhole 2 (specifically for seting up the hole of the close shrouding control switching of the warp on transportation tank wagon 1) and sample. The sampling hose 3 is made of a polytetrafluoroethylene plastic pipe and can be bent to a certain degree, so that the sampling hose is matched with the actions of the sampling machine bracket 5 and the sampling lifting lever 4 and is not easy to be corroded by a liquid sample collected from the transportation tank car 1; the sample settlement head is installed to the one end (front end) of sample hose 3, and the sample settlement head adopts a small segment stainless steel tube to process and forms to the card is fixed on 3 tip lateral surfaces of sample hose, has increased the weight of this tip (not influencing the sampling and has played the counter weight effect simultaneously), makes sample hose 3 stretch into the sample site of the different degree of depth in the transportation tank wagon 1 along tank wagon manhole 2 more easily.
Referring to fig. 2, the sampling process of the sampling bottle 7 is based on a vacuum suction principle, that is, the liquid sampling machine is further equipped with a sampling bottle vacuum pumping system, the system includes a vacuum pump 10, a buffer bottle 11 and a vacuum suction pipeline 12, the vacuum suction pipeline 12 includes an air duct communicating the vacuum pump 10 and the buffer bottle 11, and an air duct communicating the buffer bottle 11 and the sampling bottle 7.
