Definitions

  • the invention relates to a device for taking liquid samples from a storage tank, in particular for taking petroleum and petroleum product samples to prove their properties.
  • DE 11 69 851 A discloses a device for the safe removal of liquid samples from different levels of a storage tank.
  • one or more suction tubes are provided, whose intake openings are height-adjustable or arranged in different planes. Their discharge openings end via a three-way cock in a withdrawal vessel, from which the liquid can be drained after switching the three-way cock.
  • US 2,675,706 a device for taking liquid samples from a storage tank is known which has a manifold which is provided near the bottom of the storage tank with the manifold a number Sentern ⁇ ahmerohre are connected, the one side, that is open on the top, and the underside with the Manifold are connected.
  • the sampling tubes form a unit which is pivotable with respect to the storage tank, so that their upper-side openings are each capable of removing a liquid sample from a defined plane of the storage tank.
  • a device for taking liquid samples which consists of a sampling valve and vertical tubes whose lower ends protrude from Tankrä ⁇ dem and are connected via hahne to a manifold.
  • a disadvantage of the known device is the difficulty of sampling, since it is necessary to manually discharge the products contained in the vertical tubes and subsequently to return them or to dispose of the liquid samples used as a sample to determine their properties and subsequently unusable.
  • vacuum pump generally refers to a vacuum source with which a liquid is conveyed from a storage tank, preferably lifted can, such as a self-priming pump, such as a gear pump.
  • the device shown in the figure for taking liquid samples from a storage tank 4 consists essentially of a removal valve 1, vertical tubes 2, which are mounted within the storage tank 4, the ends of which lead out of the storage tank 4 and connected via valves 3 to a manifold 5 are. Further, a vacuum pump 6 is provided, which is connected with its input side at the top of the manifold 5 and with its output side at the bottom of the bleed valve 1. The vacuum pump 6 is connected via a return valve 7 and a return pipe 8 at the lower part of the storage tank 4.
  • All parts of the device for taking liquid samples from a storage tank 4, both those inside the storage tank 4 and those located outside the storage tank 4, are in accordance with current regulations for safe assembly and safe operation of the storage tank according to the characteristics carried out and mounted the stored product.

  • the openings have a smaller diameter than the diameter of the vertical tubes.
  • the length of the spigots and thus the length of the openings is determined by hydraulic calculation in relation to the uniform removal of the determined liquid product.
  • the device for taking liquid samples from a storage tank 4 works as follows. Before sampling, all valves 3 or at least those connected to the tubes 2, the ends of which are located below the liquid level in the storage tank 4, are opened. The extraction valve 1 remains shut off. The return valve 7 is opened, the vacuum pump 6 is switched on. Part of the liquid is pumped from the vertical tubes 2 via the return pipe 8 into the lower part of the storage tank 4. The running time depends on the volume of the liquid in the vertical tubes 2 and 5 in the manifold. Thereafter, all the valves 3 are shut off, with the exception of one of the valves 3, from which the sample is needed.
  • the vacuum pump 6 is turned off, the return valve 7 is also shut off.
  • the removal valve 1 is opened, the vacuum pump 6 is switched on, and the necessary sample length of the liquid is removed from the vertical tube 2.
  • the valve 3 of the operated pipe remains open. Subsequently, the vacuum pump 6 is turned off. The removal valve 1 and the previously opened valve 3 are shut off.

Abstract

L'invention concerne un dispositif de prélèvement d'échantillons de liquide dans une cuve de réserve et en particulier d'un prélèvement d'échantillons de pétrole ou de produits pétroliers pour détecter leurs propriétés. Le résultat technique que l'on peut obtenir avec l'invention est un prélèvement plus simple des échantillons dans les plans dans lesquels les échantillons doivent être prélevés et une correspondance plus étroite entre les propriétés de chaque échantillon et les propriétés du produit situé au plan correspondant de prélèvement de l'échantillon. Ce résultat technique est obtenu en utilisant une pompe à vide qui est raccordée dans le haut à un tube de collecte, dans le bas à une soupape de prélèvement et par l'intermédiaire d'un clapet anti-retour et d'une tubulure de renvoi à la partie inférieure de la cuve de réserve.
