Description

Technical Field

[0001] The utility model relates to the technical field of experimental equipment, in particular to a batch filtering spectrum sampling device. Background Art

[0002] Standard GB38400-2019 "Limit Requirements for Toxic and Hazardous Substances in Fertilizers" clearly stipulates the detection method for the harmful element "thallium" in fertilizer samples. This method mainly includes digestion, extraction and other processing steps to prepare the sample solution to be tested. Subsequently, these sample solutions need to be transferred to the injection bottle and then placed in the inductively coupled plasma emission spectrometer to complete the measurement. For the determination of multiple fertilizer samples, multiple injection bottles need to be prepared accordingly. These injection bottles are placed in the injection bottle detection box of the spectrometer in a preset order to ensure the accuracy and consistency of the test.

[0003] However, although the existing technical means have simplified the experimental process to a certain extent, such as placing the injection bottles by marking specific areas on the experimental table and marking them with numbers, there are still many problems in actual operation. For example, when the operator needs to take a single injection bottle, due to the close arrangement between the injection bottles, it is easy to accidentally touch other injection bottles, which will not only interrupt the experimental process, but also may cause safety risks; at the same time, since the finished test solution is usually turbid, it must be filtered before injecting it into the injection bottle, and the existing filtration method is usually to use a syringe with a filter head to inject the test solution into the injection bottle, but this method can only handle one injection bottle at a time, and the efficiency is relatively low, especially when dealing with a large number of samples, which will significantly increase the time and labor costs required for the experiment; in addition, the commercial injection bottles currently compatible with plasma emission spectrometers are mostly open, and the foul-smelling gas volatilized by the sample solution is not good for the health of the operator.

[0042] [Example 1]

[0043] Please refer to Figure 1-6 A batch filtering spectrum sampling device comprises a bottle rack, a filtering funnel 8 and a sampling bottle 7, wherein the bottle rack comprises a base frame 1, wherein the base frame 1 comprises a connecting plate 101, and a left vertical plate 102 and a right vertical plate 103 which are symmetrically arranged, wherein the front ends of the left vertical plate 102 and the right vertical plate 103 are respectively fixedly connected to the left and right ends of the connecting plate 101 as a whole, and vertical guide posts 104 are fixedly arranged upward at the front and rear ends of the left vertical plate 102 and the right vertical plate 103;

[0044] A bottle accommodating box 2 for accommodating the injection bottle 7 is provided between the left vertical plate 102 and the right vertical plate 103. The bottle accommodating box 2 can slide in the front-to-back direction relative to the left vertical plate 102 and the right vertical plate 103. The front end of the bottle accommodating box 2 can cooperate with the connecting plate 101 for a stop, and the rear end of the bottle accommodating box 2 is provided with a first handle 201 for the user to pull out. The user can pull the bottle accommodating box 2 out of the base frame 1 according to usage requirements and place it on a suitable work surface for easy operation.

[0045] The bottle accommodating box 2 is provided with an accommodating cavity 202, and a plurality of bottle locating holes 203 leading to the accommodating cavity 202 are opened downward on the upper surface of the bottle accommodating box 2, and the diameter of the bottle locating holes 203 is set corresponding to the bottle body of the injection bottle 7;

[0046] A movable plate 3 is horizontally provided above the bottle body accommodating box 2, which is slidably matched with the guide column 104. A plurality of bucket body positioning holes 301 for the narrow neck of the filter funnel 8 to extend into are opened downwardly through the upper surface of the movable plate 3. When the bottle body accommodating box 2 moves forward to the stop limit position with the connecting plate 101, the bucket body positioning holes 301 correspond coaxially with the bottle body positioning holes 203 one by one. A positioning seat ring 302 is coaxially provided on the movable plate 3 above each bucket body positioning hole 301. The positioning seat ring 302 is provided with an inwardly inclined annular surface 303 that matches the conical body of the filter funnel 8; an anti-slip rubber ring can be provided on the inwardly inclined annular surface 303 to increase friction; the positioning seat ring 302 and the bucket body positioning hole 301 work together to stably limit the filter funnel 8.

[0047] A lifting mechanism 4 is provided above the movable plate 3 for driving the movable plate 3 to slide up and down along the guide column 104. The movable plate 3 is raised or lowered by the lifting mechanism 4 so that the lower end of the filter funnel 8 extends into or out of the sample injection bottle 7.

[0048] The lifting mechanism 4 can adopt common structures such as a scissor mechanism, a screw mechanism, etc., and can also use a small cylinder, an oil cylinder, etc.

[0049] As a preferred solution, in order to leave sufficient filtering space, a first reinforcing rod 105 is transversely arranged between the guide columns 104 at the front ends of the left vertical plate 102 and the right vertical plate 103, and a second reinforcing rod 106 is transversely arranged between the guide columns 104 at the rear ends of the left vertical plate 102 and the right vertical plate 103, and the first reinforcing rod 105 and the second reinforcing rod 106 are both arranged above the movable plate 3; the lifting mechanism 4 includes a rotating rod 401, which is arranged between the first reinforcing rod 105 and the second reinforcing rod 106 along the front-back direction, and the rotating rod 401 is rotatably installed between the first reinforcing rod 105 and the second reinforcing rod 106 through a bearing, and at least one rope drum 402 is fixedly and coaxially sleeved on the rotating rod 401, and a lifting rope 403 is arranged on the rope drum 402, and the other end of the lifting rope 403 is connected to the movable plate 3. The rotating rod 401 drives the rope drum 402 to rotate synchronously, realizes the retraction and release of the lifting rope 403, and then drives the movable plate 3 to move up and down. In this embodiment, the rotating rod 401 is arranged in the middle of the first reinforcing rod 105 and the second reinforcing rod 106, and there are two rope winding drums 402, which are respectively arranged at the front and rear ends of the rotating rod 401. This is conducive to uniform force on the movable plate 3 and will not interfere with the filter funnel 8.

[0050] The rotating rod 401 can be driven by a motor, such as installing a small stepping motor on the base, and the output end of the stepping motor is connected to the rotating rod 401 through a belt drive, or it can be driven manually. Specifically, one end of the rotating rod 401 passes through the second reinforcing rod 106 backward and extends out, and a hand wheel 404 is fixedly installed on the extended end, and a locking plate 405 that cooperates with the hand wheel 404 is fixedly provided between the hand wheel 404 and the second reinforcing rod 106. The hand wheel 404 is provided with a first locking hole 406, and a plurality of second locking holes 407 are evenly distributed along the circumference on the locking plate 405. The first locking hole 406 can be locked with the second locking hole 407 by a cylindrical locking member (such as a bolt, a pin, etc.) to limit the rotation of the rotating rod 401.

[0051] The positioning seat ring 302 includes a seat body 3021 fixedly arranged on the movable plate 3, and a ring body 3022 screwed on the seat body 3021, and the inwardly inclined annular surface 303 is arranged on the inner side of the ring body 3022. In this way, by replacing the ring body 3022 of different sizes, various filter funnels 8 of different specifications can be adapted.

[0052] A support foot 5 is provided below the base frame 1, and a foot pad is provided below the support foot 5. This can provide a good support and anti-slip effect.

[0053] Working principle: When filtering is required, the user first places the sample injection bottle 7 in the bottle body positioning hole 203 of the bottle body holding box 2 to ensure stability, and then inserts the narrow neck part of the filter funnel 8 into the bucket body positioning hole 301 of the movable plate 3, and lowers the movable plate 3 through the hand-cranked wheel 404 of the lifting mechanism 4 until the narrow neck lower end of the filter funnel 8 extends into the sample injection bottle 7, then lays filter paper on the filter funnel 8, pours the solution to be filtered into the filter funnel 8, and allows the solution to flow into the sample injection bottle 7 through the filter paper. After the amount of solution in all the sample injection bottles 7 reaches the experimental requirements, the movable plate 3 is raised through the hand-cranked wheel 404 of the lifting mechanism 4, and the filter funnel 8 is separated from the sample injection bottle 7 to prepare for subsequent spectral analysis.

[0054] [Example 2]

[0055] The present embodiment is further improved over the embodiment 1 in that, in order to facilitate the user to transfer the sample injection bottles 7 in batches to the sample injection bottle detection box 6 on the spectrometer after the filtration is completed, the bottle body receiving box 2 is configured as a split structure.

[0056] The bottle accommodating box 2 includes a box body 204 with an opening at the bottom. A bottom plate 205 capable of closing the opening is provided below the box body 204 . The bottom plate 205 is used to support the sample injection bottle 7 during filtration. The accommodating cavity 202 is formed between the box body 204 and the bottom plate 205 .

[0057] A flexible snap ring 206 is provided in each bottle body positioning hole 203, and the flexible snap ring 206 can cooperate with the bottleneck of the injection bottle 7 to limit the downward movement of the injection bottle 7 from leaving the bottle body receiving box 2. The flexible snap ring 206 can be made of rubber or silicone, and its outer portion is fixedly connected to the inner edge of the bottle body positioning hole 203. When the upper portion of the injection bottle 7 is subjected to a certain downward pressure, the inner circle of the flexible snap ring 206 is recessed downward and disengaged from the bottleneck of the injection bottle 7, so that the injection bottle 7 can be downwardly separated from the box body 204.

[0058] The bottom plate 205 is slidably mounted below the box body 204 . A second handle 207 is provided at the rear end of the bottom plate 205 for the convenience of the user to pull out. An anti-skid pressure pad 208 is provided below the bottom plate 205 .

[0059] The accommodating cavity 202 is arranged correspondingly to the injection bottle detection box 6 of the spectrometer, so that the box body 204 can be covered on the injection bottle detection box 6; accordingly, the bottle body positioning hole 203 is arranged correspondingly to the injection bottle placement hole 601 of the injection bottle detection box 6 on the spectrometer. When in use, only the bottom plate 205 needs to be pulled out, and the box body 204 can be covered on the injection bottle detection box 6, and the injection bottle 7 just corresponds to the injection bottle placement hole 601.

[0060] Working principle: when the sampling bottles 7 need to be transferred in batches after the filtration is completed, the user first pulls out the bottom plate 205 of the bottle body accommodating box 2 backwards. At this time, although the sampling bottle 7 loses the direct support from the bottom, it will not fall due to the action of the flexible clamping ring 206. Then the box body 204 containing the sampling bottle 7 is moved to the top of the sampling bottle detection box 6 of the spectrometer, ensuring that the sampling bottle 7 on the bottle body accommodating box 2 is aligned with the sampling bottle placement hole 601 on the detection box. Then the box body 204 is downwardly covered on the sampling bottle detection box 6. At this time, the middle of the bottom of the sampling bottle 7 falls into the sampling bottle placement hole 601 of the detection box, and the upper part is exposed outside the box body 204. Finally, take out the bottom plate 205 that was previously pulled out, place it above the sampling bottle 7 and press it down gently to deform the flexible clamping ring 206, release the sampling bottle 7, and make it fall into the sampling bottle placement hole 601 of the detection box.

[0061] [Example 3]

[0062] Please refer to Figure 7 The further improvement of this embodiment over the embodiments 1 and 2 is that, in order to prevent the sample solution from emitting foul smelling substances during the experiment, which is harmful to the health of the operator, an anti-volatile structure is provided inside the injection bottle 7.

[0063] Specifically, a convex ring 701 is provided at the bottleneck of the injection bottle 7, and at least two odor shielding plates 702 are provided between the convex ring 701 and the bottle mouth of the injection bottle 7. The odor shielding plates 702 are stacked on the convex ring 701, and an anti-collision hole 703 is provided at the center of each odor shielding plate 702, and the anti-collision hole 703 is used for the liquid outlet end of the filter funnel or the injection needle of the spectrometer to pass through. In particular, the aperture of the anti-collision hole 703 decreases from bottom to top to accommodate filter funnels or injection needles of spectrometers of different sizes.

[0064] For example, in this embodiment, there are 4 layers of odor shielding plates 702. When in use, according to the size of the filter funnel outlet and the spectrometer injection needle used, remove the odor shielding plates 702 whose anti-collision holes 703 have a smaller aperture than the filter funnel outlet or the spectrometer injection needle, and only keep those odor shielding plates 702 whose aperture is greater than or equal to the filter funnel outlet or the spectrometer injection needle. When the odor in the sample solution evaporates upward, the odor shielding plates 702 can effectively block it, thereby reducing the adverse effects on the health of the operator.

[0065] The utility model provides a bottle accommodating box 2 and places the sample injection bottle 7 therein, thereby effectively avoiding the sample injection bottle 7 from tipping over or being damaged due to accidental touching by the user, thereby ensuring the continuity and safety of the experiment; by providing a movable plate 3 and a lifting mechanism 4, the accurate positioning and stable cooperation of the filter funnel 8 and the sample injection bottle 7 are ensured, and batch filtration operation of the finished test solution is realized, the experimental time is shortened, and the experimental efficiency is improved; the bottle accommodating box 2 adopts a design of a separate box body 204 and a bottom plate 205, which can realize the batch transfer of the sample injection bottle 7, which not only further improves the efficiency of the experiment, but also avoids erroneous experimental results caused by misplaced numbers and reduces experimental errors; by providing an odor shielding plate 702 in the sample injection bottle 7, the escape of malodorous gases in the sample injection bottle 7 is effectively blocked, reducing the adverse effects of the experiment on the health of the operator.

[0066] Obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
