Barreled fluid oil sampling device

Abstract

The invention discloses a barreled fluid oil sampling device, which is formed by nesting an inner pipe (1) with a positioning ring, a middle pipe (2) with the positioning ring and an outer pipe (3) with the positioning ring; two ends of the inner pipe (1) are closed to play a role of a piston with a piston rod; two ends of the middle pipe (2) are communicated with each other; and the upper end ofthe outer pipe (3) is opened, the lower end of the outer pipe (3) is provided with a feeding port (3-2) to be connected with a base (3-3), and the base is provided with a sealing plug (3-4). The barreled fluid oil sampling device has characteristics of standard fluid oil sampling operation, good stability, representativeness, fairness, high accuracy and simplicity and high efficiency in operation.

Description

1. Technical field [0001] The invention relates to an organic chemical liquid material detection instrument and equipment, in particular to a barreled liquid oil sampling device for raw oil in biodiesel production. 2. Background technology [0002] The main raw material for the production of biodiesel is waste animal and vegetable oils, which are commonly referred to as waste oil, hog oil and frying oil in the catering industry. When purchasing these oils, it is necessary to check the basic parameters such as the acid value, iodine value, saponification value and water impurity content (ie moisture and impurity content) of the oil products to determine the quality of this batch of oil products; the water in these indicators Miscellaneous content is a very important index. Since it involves the content of net oil, if the sampling test results of water and miscellaneous content is higher than the contract index, customers often raise objections, and if it is lower than the con...

Problems solved by technology

When purchasing these oils, it is necessary to check the basic parameters such as the acid value, iodine value, saponification value and water impurity content (ie moisture and impurity content) of the oil products to determine the quality of this batch of oil products; the water in these indicators Miscellaneous content is a very important index. Since it involves the content of net oil, if the sampling test results of water and miscellaneous content is higher than the contract index, customers often raise objections, and if it is lower than the contract index, it will cause economic losses for the purchaser.

Since the development of biodiesel, there is no uniform standard for the sampling method of raw oil. At present, the sampling device for liquid oil in barrels of raw oil generally adopts PVC sleeve sampler, which is composed of two PVC pipes with inner and outer pipes. Tube, the inner tube is 20-30cm longer than the outer tube, and the two ends of the inner tube are sealed and assembled

The advantage of this sampler is that it is convenient to check the oil quality of most points in the barrel, but the defect is that it lacks credibility by taking equal parts samples from the upper, middle, and lower heights of the barrel as the average sample of the barrel of raw oil , the detected water impurity content error is relatively large, not representative
