Description

Technical Field

[0001] The invention relates to the technical field of methanol content detection in liquor, and in particular to a portable detection device for methanol content in liquor. Background Art

[0002] Methanol is highly toxic to the human body, because methanol will be oxidized into formaldehyde and formic acid (formic acid) which are more toxic than methanol during human metabolism. Therefore, drinking alcohol containing methanol can cause blindness, liver disease, and even death. If you drink more than 4 ml by mistake, you will experience poisoning symptoms. More than 10 ml can cause blindness due to permanent damage to the optic nerve, and 30 ml can cause death. After the production and processing of liquor is completed, a detection device is needed to detect its methanol content. In the process of detecting the methanol content of liquor, potassium permanganate-phosphoric acid solution, oxalic acid-sulfuric acid solution and fuchsin-sulfurous acid solution are added in turn, and then the methanol content in the liquor is determined by colorimetry.

[0003] According to the application number: CN201720998914.0, a portable methanol detection pen belongs to the technical field of methanol detection, including a pen body and a pen tip. The interior of the pen body is provided with a accommodating chamber, and the accommodating chamber is provided with a wine adding tube and a liquid storage tube for containing reagents. The pen tip is arranged at one end of the pen body, and the interior of the pen tip is provided with a reaction chamber. The wine adding tube can absorb the wine to be tested and add it into the reaction chamber. The end of the liquid storage tube close to the pen tip is provided with a liquid outlet, and a quantitative switch is provided at the liquid outlet. The liquid in the liquid storage tube can flow into the reaction chamber through the liquid outlet.

It is unable to mix and stir the white wine to be tested and the added solvent, resulting in their inability to fully react, which seriously affects the detection effect and reduces the detection efficiency. At the same time, the detection device has no protective effect, resulting in it being easily squeezed and damaged by external objects when carried, which seriously affects its service life. For this reason, we provide a portable detection device for the methanol content in white wine. Summary of the invention

[0034] Furthermore, by providing a connecting spring 75 , a rigid collision between the push block 69 and the pressure sensor 77 can be avoided, and the elastic force of the connecting spring 75 can protect the pressure sensor 77 .

[0035] Positioning grooves 8 are provided on the left and right sides of the bottom of the sealing plate 4, and a positioning block 9 is fixedly connected to the top of the transparent mixing shell 3 and the position corresponding to the positioning groove 8. The top of the positioning block 9 passes through the positioning groove 8 and extends to the inside thereof to contact the inner wall of the positioning groove 8. A first iron block 10 is fixedly connected to the top of the positioning block 9, and a first electromagnet 11 is fixedly connected to the top of the inner wall of the positioning groove 8. The left and right sides of the top of the sealing plate 4 are fixedly connected to the bottom of the transparent storage shell 5 through a top plate 12. Two partition plates 13 are fixedly connected to the inner wall of the transparent storage shell 5. A fixing plate 14 is fixedly connected to the inner wall of the transparent storage shell 5 and located on the left side of the partition plate 13. The right side of the fixing plate 14 is fixedly connected to the left side of the partition plate 13, and a material guide pipe 15 is fixedly connected to the left side of the partition plate 13 and the bottom of the transparent storage shell 5.

[0036] Furthermore, the two material guide pipes 15 located on the left side and the side close to the sealing plate 4 sequentially penetrate the fixed plate 14, the transparent storage shell 5, the sealing plate 4 and the transparent mixing shell 3 and extend to the interior of the transparent mixing shell 3. The bottom end of the material guide pipe 15 located on the right side sequentially penetrates the transparent storage shell 5, the sealing plate 4 and the transparent mixing shell 3 from top to bottom and extends to the interior of the transparent mixing shell 3. Solenoid valves are provided on the three material guide pipes 15.

[0037] The left and right sides of the transparent storage shell 5 are fixedly connected with sliders 16, and the left and right sides of the inner wall of the protective shell 1 are provided with slide grooves 17 adapted to the sliders 16. The side of the slider 16 close to the slide groove 17 passes through the slide groove 17 and extends to the inside thereof to slide in contact with the inner wall of the slide groove 17. The bottom of the slider 16 is fixedly connected with a second electromagnet 18, and the bottom of the inner wall of the slide groove 17 is fixedly connected with a second iron block 19. The top of the sealing plate 4 is fixedly connected with a stirring motor 20, and the bottom end of the output shaft of the stirring motor 20 passes through the sealing plate 4 and the transparent mixing shell 3 from top to bottom in sequence and extends to the inside of the transparent mixing shell 3. The bottom end of the output shaft of the stirring motor 20 is fixedly connected with a stirring rod 21.

[0038] Furthermore, as shown in the figure, at this time, the first electromagnet 11 and the second electromagnet 18 are not turned on and have no suction force. When the liquor needs to be tested, the first electromagnet 11 and the second electromagnet 18 are turned on to avoid wasting energy.

[0039] Furthermore, the pressure sensor 77, the first electromagnet 11, the second electromagnet 18 and the stirring motor 20 are electrically connected to the controller respectively, the battery powers the electrical equipment, and the control circuit can be implemented by simple programming by technicians in this field. It is common knowledge in this field and will not be elaborated here.

[0040] Furthermore, by providing a partition plate 13 and a fixing plate 14, the transparent storage shell 5 is divided into three storage chambers, and the three storage chambers store potassium permanganate-phosphoric acid solution, oxalic acid-sulfuric acid solution and fuchsin-sulfurous acid solution in order from top to bottom.

[0041] By means of the cooperation among the mounting groove 71, the adjusting block 72, the fixing rod 73, the stopper 74, the connecting spring 75, the adjusting plate 76, the pressure sensor 77, the positioning groove 8, the positioning block 9, the first iron block 10, the first electromagnet 11, the slider 16, the slide groove 17, the second electromagnet 18 and the second iron block 19, the stability of the protective shell 1 when the transparent mixing shell 3 is used is ensured, so that the protective shell 1 can be stably fixed in one position, and the phenomenon of the protective shell 1 suddenly falling when the transparent mixing shell 3 is used is avoided, so as to avoid affecting the use of the transparent mixing shell 3. Meanwhile, the sealing plate 4 and the transparent mixing shell 3 can be disassembled later, so that the stirring structure can be disassembled for cleaning and maintenance, thereby improving the flexibility during use.

[0042] When in use, the whole device can be driven by the carrying handle. When testing liquor, the two push blocks 69 are pushed by hand to move toward each other, and the push block 69 drives the moving block 64 to move through the connecting block 610, and the moving block 64 squeezes the buffer spring 65 to move, and the moving block 64 drives the inserting block 66 to move away from the slot 67. At this time, the push block 69 on the left side moves to the right and just separates from the pressure sensor 77, so that the pressure sensor 77 drives the adjusting block 72 to squeeze the connecting spring 75 to the right through the adjusting plate 76. The pressure sensor 77 senses the pressure value and transmits the signal to the controller, and the controller turns on the first electromagnet 11 and the second electromagnet 18, so that the first electromagnet 11 and the second electromagnet 18 generate suction, and the first electromagnet 11 and the first iron block 10 are attracted to each other, which ensures the stability of the sealing plate 4 and the transparent mixing shell 3 when connected, and thus ensures the stability of the stirring motor 20 when working;

[0043] When the insert block 66 is completely pulled out of the slot 67, the force pushing the push block 69 remains unchanged, and at the same time, a force driving the push block 69 upward is added, the push block 69 drives the protective shell 1 to move upward, the protective shell 1 drives the card slot 63 and the card block 61 to separate, and the protective shell 1 drives the slide slot 17 to move upward. When the second iron block 19 and the second electromagnet 18 contact each other, the second electromagnet 18 adsorbs and fixes the second iron block 19, thereby ensuring the stability of the protective shell 1 when it moves to the position corresponding to the transparent storage shell 5;

[0044] Liquor is fed into the transparent mixing shell 3 through the liquor feeding pipe, and then the solenoid valve on the left guide pipe 15 is opened by the controller, so that an appropriate amount of potassium permanganate-phosphoric acid solution is discharged into the transparent mixing shell 3, and then the stirring motor 20 is started, and the stirring motor 20 drives the stirring rod 21 to rotate and mix and stir it through the output shaft. After the stirring is completed, the solenoid valve on the guide pipe 15 at the middle position is opened again, so that an appropriate amount of oxalic acid-sulfuric acid solution is discharged into the transparent mixing shell 3, and stirred again by the stirring rod 21, and then the solenoid valve on the right guide pipe 15 is opened again, so that an appropriate amount of magenta-sulfurous acid solution is discharged into the transparent mixing shell 3, and stirred again by the stirring rod 21. At this time, the liquid generates a blue-purple compound, and then the standard colorimetric card is used for colorimetric comparison to obtain the methanol content. The specific colorimetric comparison case has been publicly explained, so it is not elaborated in detail here.

[0045] After the detection is completed, the valve on the discharge pipe is opened to discharge the solvent in the transparent mixing shell 3. When the stirring rod 21 and the inside of the transparent mixing shell 3 need to be cleaned, the first electromagnet 11 is turned off by the controller so that the first electromagnet 11 no longer has suction, and then the protective shell 1 is pulled upward again. The protective shell 1 drives the sealing plate 4 to move upward through the transparent storage shell 5 and the top plate 12, so that the sealing plate 4 drives the positioning groove 8 and the positioning block 9 to separate, and the sealing plate 4 drives the stirring rod 21 to be pulled out of the transparent mixing shell 3, and the stirring rod 21 and the inside of the transparent mixing shell 3 can be cleaned.
