Description

Technical Field

[0001] The present invention relates to the technical field of detection equipment for baijiu base liquor samples, and specifically provides a detection equipment for baijiu base liquor samples. Background Art

[0002] Currently, trace flavor substances often determine the flavor type, style, and quality of baijiu. Among them, many of the key flavor substances are volatile components. In recent years, in order to detect the internal components of base liquor, relevant analytical detection equipment is generally used for analysis and detection activities.

[0003] The commonly used analytical detection equipment nowadays is generally a gas chromatography-mass spectrometry (GC-MS). The GC-MS, also known as a gas chromatography-mass spectrometry analyzer, is an analytical instrument used in the fields of chemistry, biology, pharmacy, and materials science. It mainly combines a gas chromatograph and a mass spectrometer to detect the gas after the liquid is dissolved and vaporized.

[0004] Currently, when using a GC-MS to analyze and detect baijiu base liquor, the base liquor is generally directly injected into a test tube and then enters the detection module through a sampling device. However, the existing detection process has the following technical bottlenecks;

[0005] 1. Limitations in sample pretreatment: When directly injecting the base liquor, if non-target components (such as fermentation residues, trace macromolecular substances) are not fully removed, it may interfere with the chromatographic separation efficiency, resulting in the signal of the target flavor substances being masked or distorted; some hardly volatile substances (such as polysaccharides, proteins) cannot be completely decomposed during the vaporization stage, which may contaminate the ion source or block the chromatographic column, reducing the detection sensitivity;

[0006] 2. Insufficient purification ability of the equipment: Currently, the processing module used in the GC-MS has limited separation efficiency for interfering substances in complex matrices, which may affect the detection accuracy of target components.

[0007] Therefore, a detection equipment for baijiu base liquor samples is proposed to improve the pretreatment effect and analytical detection accuracy of the detection equipment for samples. Summary of the Invention

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] By setting a double filtering device, that is, under the combination of the filter frame provided inside the first filtering component and the filter plate inside the second filtering component, a double filtering structure can be formed, so as to achieve efficient and sufficient filtering of the whole white liquor base liquor, greatly reducing the non-target components inside the base liquor and improving the accuracy of subsequent detection. And with the meshing transmission of the main bevel gear, the first bevel gear and the second bevel gear, the left and right reciprocating shaking of the filter frame and the up and down reciprocating shaking of the filter plate can be carried out simultaneously, so as to accelerate the double filtering efficiency of the white liquor base liquor, thereby greatly improving the guarantee of the sample pretreatment of the white liquor base liquor and the accuracy of the subsequent analysis data.

[0021] The setting of the first filter component, that is, cooperating with the filter frame, can realize preliminary filtering and purification of the white wine base wine, and through the meshing transmission of the main bevel gear and the first sub-bevel gear, the first rotating rod can realize the circular rotation of the rotating plate connected to the top. In this way, the movable plate connected to the upper end of the rotating plate through the hollow groove can cooperate with the guide rod to make the vertical rod realize the left and right reciprocating shaking of the filter frame connected to the top, so as to speed up the filtering efficiency of the white wine base wine and reduce the clogging problem of the filter frame.

[0022] The setting of the locking piece, that is, by pressing the button, the connecting strip can be moved downward to realize the lateral opposite pushing of the vertical strips connected on both sides, so that the locking blocks docked at the lower ends of the vertical strips on both sides will realize the inward movement to quickly release the lock with the upper ends of the vertical rods, so that the filter frame as a whole can be quickly disassembled and cleaned. Subsequently, when the filter frame and the upper ends of the vertical rods are docked again, the upper ends of the vertical rods can be inserted into the docking shell through direct plug-in activities, and the locking blocks can automatically realize the plug-in locking cooperation through the rebound assistance of the elastic damper arranged on the inside, thereby ensuring the convenience of the filter frame disassembly and assembly process.

[0023] The setting of the second filter assembly, that is, the white wine base wine that has completed the preliminary filtration can flow into the processing box to contact the filter plate arranged inside the processing box for secondary filtering and purification. At the same time, the second secondary bevel gear meshing with the lower end of the main bevel gear can rotate at the same time to drive the second rotating rod to rotate. As a result, the convex rod connected to one side of the lower end of the second rotating rod will, through rotation, push the rotating drum that is abutted at the upper end. When the rotating drum moves up, it will push the stabilizing plate to make the dampers arranged on both sides of the stabilizing plate move up, and compress the compression spring connected to the upper end and move up the connecting frame connected to the bottom respectively. As a result, the built-in frame connected to the bottom of the connecting frame will move along the inside of the processing box to realize the upward movement of the filter plate, and subsequently cooperate with the rebound reset assistance of the compression spring, the dampers on both sides will automatically move down. As a result, the built-in frame drives the filter plate to move down along the inside of the processing box. As a result, the filter plate can swing up and down reciprocatingly along the inside of the processing box to help improve the secondary filtering efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

The guide rod 879 for support and moving guidance is inserted outside the vertical rod 878, and both sides of the guide rod 879 are fixedly connected to the inside of the housing 81. The filter frame 8710 is arranged at the upper end of the vertical rod 878, and the filter frame 8710 is integrally arranged in an inverted isosceles trapezoid shape. The locking member 8711 is installed in the middle inside the filter frame 8710, and the locking member 8711 is quickly locked to the upper end of the vertical rod 878.

[0036] Among them, the locking member 8711 includes a docking shell 87111, a sealing ring 87112, a button 87113, a connecting bar 87114, a vertical bar 87115, a lock block 87116 and an elastic damper 87117.

There is a sealing ring 87112 built inside the upper end of the docking shell 87111, and a button 87113 is arranged inside the sealing ring 87112. In this way, through the setting of the sealing ring 87112, the base wine can be prevented from entering the inside of the docking shell 87111. The bottom of the button 87113 is horizontally fixedly connected to a connecting bar 87114, and shafts are integrally docked at the inclined ends on the left and right sides of the connecting bar 87114.

Moreover, both sides of the vertical bars 87115 are slidably connected to the inside of the docking shell 87111. The lower ends of both sides of the vertical bars 87115 are horizontally fixedly connected to lock blocks 87116, and both sides of the lock blocks 87116 are inserted into the left and right sides inside the upper end of the vertical rod 878.

[0038] Among them, the button 87113 is vertically inserted into the inside of the docking shell 87111, and there is a spring between the button 87113 and the lower end of the docking shell 87111. In this way, when the extrusion of the button 87113 is released, the automatic upward reset of the button 87113 can be realized by the rebound assistance of the spring.

[0039] Please refer to Figure 7, the second filtering component 88 in this embodiment includes a second bevel gear 881, a second rotating rod 882, a convex rod 883, a rotating cylinder 884, a stabilizing plate 885, a damper 886, a compression spring 887, a connecting frame 888, an inner frame 889, a filter plate 8810 and a processing box 8811. The second bevel gear 881 is meshed and connected to the lower end of the main bevel gear 873. A second rotating rod 882 is inserted in the middle of the second bevel gear 881, and the lower end of the second rotating rod 882 is rotatably connected to the bottom of the protective shell 871. A convex rod 883 is installed on the outer side of the lower end of the second rotating rod 882, and the convex rod 883 is vertically installed along the side of the lower end of the second rotating rod 882. Moreover, the convex rod 883 can rotate in the same direction as the second rotating rod 882. The upper end of the convex rod 883 abuts against the rotating cylinder 884. The upper end of the rotating cylinder 884 is horizontally fixedly connected with a stabilizing plate 885, and the stabilizing plate 885 is arranged on the outer side of the lower end of the second rotating rod 882. And the middle of the stabilizing plate 885 is not in contact with the outer side of the second rotating rod 882. Dampers 886 are installed on both the left and right sides of the stabilizing plate 885, and the tops of the dampers 886 are connected to the inside of the protective shell 871.

And openings are formed at the upper ends of both the left and right sides of the processing box 8811, and the openings formed on both sides of the processing box 8811 are communicated with the openings formed on both sides of the protective shell 871.

[0040] Among them, the bottom of the rotating cylinder 884 is arranged in an inclined plane shape, and the inside of the rotating cylinder 884 is not in contact with the outer wall of the second rotating rod 882, ensuring that the rotating cylinder 884 does not rotate with the second rotating rod 882, but through the rotating upward acting force of the convex rod 883, the up and down movement is realized; the inner frame 889 is slidably placed inside the processing box 8811, and the filter plate 8810 arranged inside the inner frame 889 is installed in a plug-in manner, ensuring that the inner frame 889 can reciprocate up and down inside the processing box 8811. At the same time, the auxiliary disassembly and cleaning cooperation of the filter plate 8810 can be conveniently realized.

[0041] Working principle:

[0042] 1. When conducting the detection activity of baijiu base liquor, the sample bottles 4 carrying the baijiu base liquor can be successively placed inside the turntable 3. Driven by the intermittent rotation of the turntable 3, the sample bottles 4 can be rotated to the sampling end at the lower end of the sampling module 1. The sampling module 1 can realize the sampling and transmission activity inside the sample bottle 4 through the first controller 2 provided on the right side of the front end, so that the baijiu base liquor is transmitted to the inside of the detection module 6 through the sample transmission pipe 5 connected to the upper left end of the sampling module 1 to conduct the detection activity of the baijiu base liquor. And in cooperation with the second controller 7 provided on the left side of the front end of the detection module 6, the display of the detected data and the setting of subsequent detection steps can be realized;

[0043] 2. In order to ensure the purity of the baijiu base liquor during the detection and enhance the subsequent detection accuracy, the present application also relatively sets a double filtration device 8 on the right side of the sampling module 1. First, pour the baijiu base liquor from the upper end of the filter frame 8710, so that the baijiu base liquor passes through the filter frame 8710 to realize the preliminary filtration and purification of the sample. In order to improve the filtration effect of the filter frame 8710 on the baijiu base liquor, the motor 872 provided on the right side inside the protective shell 871 can be operated to make the motor 872 rotate the main bevel gear 873 connected to the output end. With the rotation of the main bevel gear 873, the first secondary bevel gear 874 meshing with the upper end of the main bevel gear 873 can be driven to rotate the first rotating rod 875 connected to the upper end. With the rotation of the first rotating rod 875, the rotating plate 876 connected to the upper end of the first rotating rod 875 will rotate in a circle. And the moving plate 877 connected to the upper right side of the rotating plate 876 through the hollow groove opened at the bottom can be driven by the circular rotation of the rotating plate 876 to move left and right reciprocally. Thus, the vertical rod 878 connected to the upper end of the moving plate 877 will move left and right reciprocally synchronously. At the same time, in order to ensure the stability of the left and right reciprocating movement of the moving plate 877, guide rods 879 are also horizontally inserted on both sides of the outer end of the vertical rod 878 to realize the guiding and supporting cooperation of the reciprocating horizontal movement. In this way, with the stable left and right reciprocating movement of the moving plate 877 and the vertical rod 878, the filter frame 8710 connected to the upper end of the vertical rod 878 will realize the left and right shaking activity to accelerate the filtration and purification efficiency of the baijiu base liquor, and through the shaking effect, reduce the blockage probability of the filter frame 8710 and ensure the filtration and fluidity of the baijiu base liquor. Thus, it can assist in accelerating the filtration efficiency of the baijiu base liquor;

[0044] Thirdly, when the main bevel gear 873 rotates, the rotation of the second secondary bevel gear 881 engaged at the bottom can also be realized. As the second secondary bevel gear 881 rotates, the second rotating rod 882 vertically connected to the middle of the second secondary bevel gear 881 will rotate accordingly, causing the convex rod 883 connected to the outer side of the lower end of the second rotating rod 882 to perform a circular rotation activity. During the rotation of the convex rod 883, it will cooperate with the inclined surface at the lower end of the rotating cylinder 884 to drive the overall upward movement of the rotating cylinder 884. Thus, when the rotating cylinder 884 moves upward, the stabilizing plate 885 connected to the upper end of the rotating cylinder 884 will move upward synchronously to drive the upward movement of the dampers 886 provided on both the left and right sides. When the dampers 886 on both sides move upward, the compression springs 887 provided on the outer sides of the upper ends will be compressed. At the same time, the connecting frames 888 connected to the lower ends of the dampers 886 on both sides will move upward synchronously, and the built-in frame 889 fixed to the bottom of the connecting frame 888 will drive the filter plate 8810 provided inside to move upward along the inside of the treatment box 8811. When the elastic downward push and reset of the dampers 886 are realized through the compressed compression springs 887 on both sides, the dampers 886 on both sides will assist in realizing the downward movement of the stabilizing plate 885 and the rotating cylinder 884, ensuring the tight fit between the rotating cylinder 884 and the upper end of the convex rod 883. Secondly, the connecting frames 888 connected to the bottoms of the dampers 886 on both sides will drive the downward movement and reset of the filter plate 8810 installed inside the built-in frame 889 during the downward push transmission. Thus, the filter plate 8810 will perform an up-and-down reciprocating shaking activity along the inside of the treatment box 8811. In this way, when the base liquor that has completed the preliminary filtration and purification enters the inside of the treatment box 8811 through the openings communicated with the left and right sides of the protective shell 871 and the treatment box 8811, it will perform a secondary filtration and purification activity with the filter plate 8810 that is reciprocating up and down, realizing the secondary filtration and purification of the white liquor base liquor, further improving the sample pretreatment effect, ensuring the sample quality, and ensuring the accuracy of the sample analysis data;

[0045] Fourthly, after the white liquor base liquor has completed the secondary filtration activity, it will gather at the lower end inside the housing 81. At this time, by driving the pump body 83 provided on the left side of the upper end of the housing 81, the white liquor base liquor at the lower end inside the housing 81 can be sucked into the inside of the straw 86, transmitted through the conduit 84, and flow into the sample bottle 4 placed on the upper end of the turntable 3 from the opening of the liquid injection pipe 85. In this way, there is no need for manual pouring of the white liquor base liquor, further improving the intelligence and convenience of the white liquor base liquor detection;

[0046] 5. When the filter frame 8710 needs to be cleaned later, the button 87113 provided on the upper end of the docking shell 87111 can be pressed to make the button 87113 push down the connecting bar 87114 connected to the bottom. As the connecting bar 87114 moves downward, the vertical bars 87115 connected to the shafts on both sides of the connecting bar 87114 will cooperate with the inclined hollow space corresponding to the top to move horizontally in the opposite direction with the downward movement. In this way, the locking blocks 87116 docked at the lower ends of the vertical bars 87115 on both sides will move horizontally in the opposite direction synchronously to quickly release the locking blocks 87116 on both sides of the upper end of the vertical bars 878. At the same time, when the button 87113 is pressed down, the compression of the spring at the bottom will be realized, and when the locking blocks 87116 on both sides move synchronously in opposite directions, the elastic damper 87117 docked inside the locking blocks 87116 will also realize compression activities synchronously, thereby, the locking blocks 87116 on both sides will be quickly unlocked from the upper ends of the vertical rods 878, so that the filter frame 8710 as a whole can be removed from the upper opening of the protective shell 871 for convenient cleaning activities, and when reinstalling, it only needs to align the lower end of the docking shell 87111 with the upper end of the vertical bar 87115 and insert it, and the docking installation activities can be automatically realized;

[0047] 6. When cleaning the filter plate 8810, it is necessary to open the opening and closing door 82 on the front side of the shell 81 to expose the internal frame 889 and the filter plate 8810. By pulling the filter plate 8810 outward, the filter plate 8810 can be easily moved out of the internal frame 889 to achieve quick and convenient cleaning.
