Abstract
The utility model provides a vacuum sampler for liquid food, belonging to a measuring appliance. The vacuum sampler structurally comprises a liquid storage bottle, wherein the top part of the liquid storage bottle is connected with a liquid feed pipe and an exhaust pipe; the bottom part of the liquid storage bottle is connected with a liquid drain pipe; the exhaust pipe is partitioned into two parts by a tee, wherein one part is connected with an exhaust mechanism and the other part is connected with a negative pressure mechanism; and the liquid feed pipe, the liquid drain pipe, the exhaust pipe connected with the exhaust mechanism and the exhaust pipe connected with the negative pressure mechanism are all provided with a control valve. Compared with the prior art, the vacuum sampler for liquid food has the characteristics of being reasonable in design, simple in structure, convenient to use, and the like; and with the adoption of the vacuum sampler, the whole detection process is performed in the vacuum environment, so that the detection is accurate and the working efficiency of detectors is effectively improved.
Description
Technical field
The utility model relates to a kind of measuring appliance, specifically a kind of simple in structure, food liquid vacuum sampler.
Background technology
With the closely-related industry of people's daily life in, become more meticulous in the enterprise such as food, medicine etc., quality inspection is particularly important.The quality inspector often needs sampling to come the quality inspection problem, for food liquid, sampling process is particularly important, normal temperature, normal pressure, uncovered operation are generally taked in the conventional liq sampling, sample enters sampler after sample tap flows out ingress of air, this sampling mode institute sample thief exposes to the sun and series of chemical easily occurs behind the oxygen aeration, as contains the variation of other chemical property such as the death of the anaerobions such as degraded, sulphate reducing bacteria of polymkeric substance in the polymer samples system and water quality.For avoiding as far as possible sample to expose to the sun behind the oxygen on analyzing the impact of experimental work, the anaerobism sampling and analysing becomes problem demanding prompt solution.
Summary of the invention
Technical assignment of the present utility model is to solve the deficiencies in the prior art, and a kind of food liquid vacuum sampler simple in structure, easy to use is provided.
The technical solution of the utility model realizes in the following manner, this food liquid vacuum sampler, its structure comprises liquid storage bottle, be connected with feed tube, evacuated tube at the top of liquid storage bottle, bottom at liquid storage bottle is connected with drain pipe, described evacuated tube is separated into two parts by threeway: a part is connected with emptying mechanism, and another part is connected with negative pressure mechanism, is provided with operation valve on the evacuated tube that the evacuated tube that described feed tube, drain pipe, emptying mechanism connect, negative pressure mechanism connect.
As preferably, described emptying mechanism is a minipump.
As preferably, described negative pressure mechanism is a negative pressure air cavity that is connected with evacuated tube, and the structure of this negative pressure air cavity comprises that pressing plate, two ends connect respectively the ripple connecting band of pressing plate and evacuated tube, offer the retaining valve for exhaust on the described pressing plate.
As improvement, above-mentioned ripple connecting band comprises inside and outside two-layer, is provided with back-moving spring between the described two-layer ripple connecting band.
As preferably, described liquid storage bottle is that transparent bottle and its surface uniform indicate scale.
The beneficial effect that the utility model compared with prior art produces is:
Food liquid of the present utility model with vacuum sampler have simple in structure, easy to use, the characteristics such as be skillfully constructed, can finish by minipump the making of vacuum environment during sampling, then by the negative pressure air cavity sample is pumped in the liquid storage bottle, the volume of sample can be read by the scale of liquid storage bottle, institute's sample thief quantity is accurate, guarantee the accuracy of experimental data, improve staff's checkability.
