Description
Technical Field
The invention relates to the technical field of rapid detection of harmful substances in wine, in particular to a portable rapid detection device for the harmful substances in the wine.
Background
Wine GB15037-2006 specifies the terms and definitions of wine, product classification, requirements, analytical methods, inspection rules and marks, packaging, transportation, storage. For harmful substances in wine, the methanol content of white and pink wines is required to be not more than 250mg/L according to national standard document GB15037-2006, and the methanol content of the red wines is required to be not more than 400mg/L. Coli total < 3/100 mL and bacteria total < 1/mL. The pesticide residue is based on the harmful substances introduced by grape raw materials, and contains the residues of the active ingredients of herbicides, bactericides and pesticides commonly used in the grape planting process, so that the pesticide residue content of the product is strictly required. The wine is easily affected by vibration, storage temperature, humidity and other factors, and is a perishable product; in import and export trade, the wine is subjected to links such as long-term transportation and storage, and a plurality of factors can cause the generation of related harmful substances, and meanwhile, the content requirements of the import and export trade on the related harmful substances are very strict, so that the method is essential for carrying out periodic sampling detection on related indexes in links such as purchasing, transportation and storage in the import and export operation of the wine, but the traditional sampling detection operation is as follows: on-site sampling, sample transportation and inspection, laboratory inspection and result outputting, the cycle is too long to be beneficial to the current fast-paced foreign trade activities, so that the traditional sampling inspection method has gradually been developed into rapid and timely on-site sampling inspection in recent years. For example, issued patents have been disclosed in recent years: CN202120209805.2, a device for rapidly detecting harmful substances in wine on site, is aimed at achieving rapid and convenient sampling detection of the harmful substances in wine on site. However, new problems, such as cross contamination prevention and detection accuracy, also occur in the current operation of sampling and detecting in situ. Taking Escherichia coli as an example, sampling in a traditional laboratory, quantifying the sample solution to be 0.1-1 ml, inoculating the quantified sample solution into lactose peptone culture solution, culturing for 24 hours at 37 ℃, and then controlling the detection to be completed within 10 minutes (the Escherichia coli can complete passage propagation once every 20 minutes, so the detection process needs to be controlled in time according to the detection standard). The on-site detection omits the traditional culturing step, such as the current commercial quick detection instrument for the Leided coliform bacteria, and the product model: LD-ATP, detection range 0to99999RLUs, this model short-term test appearance mainly adopts fluorescence detection principle to realize the short-term test of sample based on the swab sleeve pipe, and the rate of accuracy is high, but when detecting samples such as grape wine, need ensure that solid particulate matter filters fully in order to prevent to influence analysis result, and the principle is similar to the misread of relevant debris to the count of need rejecting when carrying out coliform thallus count, just can ensure the accuracy of measuring. Thus, the main problem in performing field tests is not in the current test instruments but in how to obtain the sample to be tested that meets the requirements of the test instrument in a limited time. The main difficulty of the process is that: in-situ sampling (cross-contamination prevention), sample filtration and accurate quantification of the sample fluid, all of which were controlled to within 10min until the end of the assay. Meanwhile, in-situ sampling such as dock noise is large and air flow fluctuation is large, traditional laboratory imbibition equipment is adopted to easily influence micro-imbibition, because the dock noise and high-intensity air flow fluctuation can cause fluctuation of peripheral air pressure, the principle of the traditional laboratory indoor imbibition equipment is to quantitatively imbibition based on ideal stable atmospheric pressure, namely, the liquid displacement amount corresponding to the piston stroke of a liquid displacement device is calibrated based on the pressure difference between negative pressure in a piston and standard atmospheric pressure, so that in-situ imbibition for a code head and the like can be based on the situation that the peripheral air pressure is unstable to cause imbibition deviation, and especially for micro-imbibition, the phenomenon that accuracy is difficult to ensure even the phenomenon that the actual imbibition amount deviation is too large to influence related detection results occurs.

Preferably, the end of the first negative pressure pipe 22 is connected with a first electric air pump 19, in this embodiment, the first electric air pump 19 is mainly used for providing negative pressure, and the problem of quantitative liquid suction of the stroke can be avoided, so that a general electric negative pressure air pump or an alternative electric piston can be selected, and driven by the motor 18, and if the general electric negative pressure air pump is selected, a pressure-sensitive sensing module can be correspondingly arranged for preventing excessive negative pressure, and the pressure-sensitive sensing module is connected with the control circuit; the end of the second negative pressure tube 29 is connected with a second electric air pump 30, which is driven by a motor 31.

Preferably, further comprising a control circuit 37 and a first control switch 32 and a second control switch 33; the first electric control valve 20, the second electric control valve 29-1, the first control switch 32, the second control switch 33, the driving motor 18 of the first electric air pump 19 and the driving motor 31 of the second electric air pump 30 are electrically connected with the control circuit 37; the first control switch 32 controls the first electric control valve 20 and the driving motor 18 of the first electric air pump to open and close; the second control switch 33 controls the second electric control valve 29-1 and the driving motor 31 of the second electric air pump to open and close.
In use, the handle 34 is held by hand, preferably in the following manner: if the first control switch 32 is pressed, the first electrically controlled valve 20 is closed, the driving motor 18 is slowly started (the first control switch 32 can be switched on by a resistor, the rotation speed of the driving motor 18 can be controlled by the pressed depth, and the liquid sucking speed can be controlled), so that the first negative pressure pipe 22 forms negative pressure, and further, the first standard bottle connected to the first scalar bottle plug 24 is caused to form negative pressure (at the moment, the diaphragm check valve 13 is closed, the second standard bottle 12 is prevented from forming negative pressure), then the sample liquid is sucked into the first standard bottle through the sampling pipe 11, the first control switch 32 can be controlled to be released when the sample liquid reaches the lower interval scale 6, and the optimal standard is that the sample liquid level is basically controlled at the scalar scale 3, but in the embodiment, as long as the sample liquid level is distributed in the upper interval scale 5 and the lower interval scale 6, the influence on the subsequent quantitative adsorption operation is not great (based on the current process limitation and cost, the volume is not required to be marked in the actual processing scale 3, if the sample liquid is not high in the actual processing scale 3, and if the liquid sucking accuracy is not great enough, and the liquid sucking accuracy is not great based on the following quality of the principle is not great, and the accuracy is not great in understanding of the following quality of the liquid sucking operation and the quality is not great quality of the scale 3); at this time, the first control switch 32 is completely released, the first electrically controlled valve 20 is opened to remove negative pressure, and the driving motor 18 is rapidly reversely reset, that is, if a piston type negative pressure pump is used, the piston is reset; then the sampling tube 11 is pulled out from the sampling tube joint 8 to finish the sampling operation; then entering a quantitative liquid suction process, and tightly plugging and sealing the sampling tube joint 8 by using a rubber plug to isolate the first and second standard bottles 12 from the field environmental air pressure; the required volume of sample fluid to be detected is then set by means of the control key 42 and the display 41, for example 1ml, at which time the second control switch 33 (which is a pure switch, preferably a switch with a cut-off function, i.e. a switch which is pressed once and then pressed once again and closed) is pressed, at which time the first electrically controlled valve 20 and the second electrically controlled valve 29-1 are both closed, the second electrically controlled air pump 30 will be activated and slowly provide a negative pressure according to the standard procedure, since the upper chamber 7 is at normal air pressure before starting the present phase, the volume of sample fluid is then calibrated between the upper interval scale 5 and the lower interval scale 6, and the total amount of air a at the end of the upper chamber 7 is substantially constant in each repetition, the liquid displacement corresponding to the negative pressure of the second electric air pump 30 is calculated based on the total amount of the gas a at the other end, and the negative pressure fluctuation factor of the one end of the upper chamber 7 in the fluctuation of the slow liquid suction of the second standard bottle 12 is measured to obtain the final liquid displacement corresponding to the total stroke of the second electric air pump 30, and in actual production, the actual requirement can be combined, for example, the liquid displacement achievable by the second electric air pump 30 is set with several limited liquid displacement such as 0.5ml, 1ml, etc., and of course, the liquid displacement corresponding to more measuring ranges can be set by exploring the negative pressure curve law. After the negative pressure is formed, the second standard bottle 12 can automatically and slowly suck liquid from the lower part of the filter screen sheet 2 through the flow pipe 10 (the micro quantitative sampling process can be obviously accelerated), and when the negative pressure at the end of the second standard bottle 12 is the same as the negative pressure at the end of the upper chamber 7, the liquid sucking to the second standard bottle 12 is stopped; then the system controls the second electric control valve 29-1 to open, so that the inverted air bubbles are seen on the flow pipe 10, the inverted suction is only to reversely suck the residual liquid on the flow pipe 10, and the upper end of the flow pipe 10 is higher than the highest liquid level in the second standard bottle 12, so that the liquid amount in the second standard bottle 12 cannot be influenced (after the second electric control valve 29-1 is opened, the second standard bottle 12 recovers the standard air pressure, and the end of the upper chamber 7 is also negative pressure at the moment to form the reverse negative pressure), and the effect of the reverse negative pressure is realized: 1. the quantitative micropipette can be more intuitively found to be completed; 2. the formation of the reverse negative pressure is mainly based on the consideration of on-site operation, and there is a certain movement and vibration in the operation process, and the inaccuracy of the traditional on-site operation is caused by the interference caused by the air pressure, and a great reason is caused by the interference caused by the manual operation, in this embodiment, since after the micro quantitative liquid suction stage is finished, a reverse negative pressure system can be constructed, even if the vibration factor exists in the operation, the sample liquid can not continue to flow from the flow tube 10 into the second standard bottle 12, so that the quantitative accuracy is ensured; the second measuring flask 12 is then pulled away from the flow tube 10 and the second control switch 33 is released, whereupon all electronic components are reset for the next iteration. In the related detection, the touch screen 43 is detected according to the existing corresponding detection standard, which belongs to the prior art category and is not a main innovation point of the present invention, so that the present invention is not described too much.
In order to provide further detection functionality, an associated detection probe 38, such as a fluorescence analysis probe or a methanol analysis probe, etc., may also be provided within the second scalar bottle plug 27, which is also connected to the control circuit 37, in order to provide further functional rapid detection. If the detection module is used, the second graduated flask 15 may be made of opaque material.
