Description

Technical Field

[0001] This utility model relates to the field of ground gas metal measurement technology, and in particular to a ground gas nano-metal particle collection device. Background Technology

[0002] The measurement of ground-atmosphere nanoparticles is mainly divided into two types: active and passive. The active ground-atmosphere method (negative pressure extraction method) mainly consists of a suction rod, filter, collection and extraction device, etc. The collection agent mainly includes two types: liquid and solid. The liquid collection agent mainly uses ultrapure dilute acid solution. The core component of the ground-atmosphere equipment based on liquid collection agent is the gas washing device. The existing technology uses a U-shaped bottle to capture nanoparticles by bubbling.

[0003] The method of using a gas tube to bubble allows trace metals in the ground gas to react with the collector. However, this method may result in excessively large bubbles and excessively fast overflow rates, leading to a small gas-liquid contact surface area. This results in insufficient reaction between the nanoparticles carried by the bubbles and the liquid, preventing the metal particles in the ground gas from being fully washed off. Consequently, the concentration of metal particles in the solution is low, affecting the measurement structure of metal content in the soil. Some researchers have adopted a dual-collector series method (i.e., setting up two gas washing bottles) to improve the nanoparticle capture efficiency. However, the mixed sample from the two bottles needs to be concentrated before testing, which may lead to contamination between the samples. Utility Model Content

[0004] In view of this, embodiments of the present invention provide a ground-atmosphere nano-metal particle collection device to solve the technical problem of low collection efficiency and poor effect in the prior art method of inserting a trachea into the collecting agent for bubbling.

[0005] An embodiment of this utility model provides a ground-atmosphere nano-metal particle collection device, comprising:

[0006] The frame has mounting holes;

[0007] A collection bottle includes a bottle body with an open top and a bottle cap. The bottle cap is detachably connected to the open end of the bottle body. The bottle cap is provided with an air inlet pipe and an air outlet pipe that pass through it. The lower end of the air inlet pipe extends to the lower part of the bottle body and is provided with a bubbler. The collection bottle also contains a movable magnetic particle.

[0008] A magnetic stirring mechanism is disposed within the frame and includes a motor and a magnetic component. The magnetic component is rotatably disposed within the placement hole. The motor is connected to the magnetic component. The bottom of the bottle can be placed within the placement hole such that the magnetic element and the magnetic component are positioned opposite each other. The motor can drive the magnetic component to rotate, thereby causing the magnetic element to rotate within the bottle and stirring the solution within the bottle.

[0009] Furthermore, the magnetic component comprises four magnets, which are evenly distributed around the circumference.

[0010] Furthermore, the inside of the collection bottle is equipped with a filter screen, which prevents the magnetic particles from being easily poured out with the solution.

[0011] Furthermore, the filter screen is an annular shape with a through hole in the center, allowing the magnetic particle to be removed from the collection bottle.

[0012] Furthermore, a first mounting ring and a second mounting ring are respectively connected to the inner and outer sides of the filter screen, with the first mounting ring abutting against the inner wall of the collection bottle.

[0013] Furthermore, the magnetic stirring mechanism is provided with an mounting plate at its upper end, and the mounting plate is provided with at least one clip frame, and the collection bottle is engaged with the clip frame.

[0014] Furthermore, the bubbler is a sand core bubble head, with multiple bubble-generating micropores uniformly penetrating its exterior.

[0015] Furthermore, the magnet is connected to the output end of the motor via a magnetic coupling.

[0016] Furthermore, the placement hole is a stepped hole, and the bottle body and the stepped surface of the stepped hole abut against each other.

[0017] Furthermore, the bottom of the frame is provided with two ground nails, and the bottom of the frame has a receiving groove. Both ground nails are rotatably set in the receiving groove and can be screwed out of the frame for fixing the frame to the ground for use.

[0018] The beneficial effects of the technical solution provided by the embodiments of this utility model are as follows: The magnetic stirring enhanced ground gas metal measurement device of this utility model adopts a magnetic stirring mechanism, which drives the magnetic particle to rotate through contactless power transmission, thereby achieving efficient and uniform stirring of the solution and ensuring that the ground gas and solution are fully mixed, thus improving the metal ion collection efficiency and measurement accuracy. Secondly, the introduction of the sand core bubbling head enables the ground gas to be evenly dispersed in the solution, increasing the contact area between the ground gas and the solution and further improving the measurement effect. In addition, the frame and seat design of the device ensures the stable installation and positioning of the collection bottle, enhancing the overall stability of the device. The filter design effectively prevents the magnetic particle from being poured out with the solution, avoiding the risk of magnetic particle loss. At the same time, the annular structure with a through hole in the middle facilitates the removal and replacement of the magnetic particle, further improving the ease of use of the device.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be further described below with reference to the accompanying drawings. The following description presents a preferred embodiment of several possible embodiments of this utility model, intended to provide a basic understanding of the utility model, but not intended to identify the key or decisive elements of the utility model or to limit the scope of protection sought.

[0027] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0028] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0029] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures. Also, it should be understood that, for ease of description, the dimensions of the various parts shown in the figures are not drawn to actual scale.

[0030] In the description of this utility model, it should be noted that the circuits, electronic components and modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated. The content protected by this utility model does not involve any improvement to the internal structure and method.

[0031] It should be further noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] Please refer to Figures 1 to 6 The present invention provides a ground-atmosphere nano-metal particle collection device, including a frame 2, a collection bottle 1, and a magnetic stirring mechanism. The collection bottle 1 includes a bottle body and a bottle cap 3. The bottle body contains a liquid collection agent. An air inlet pipe 31 and an exhaust pipe 32 are provided through the bottle cap 3. One end of the air inlet pipe 31 extends to the lower part of the bottle body.

[0033] It should be noted that the collection bottle 1 uses a 50ml high borosilicate glass bottle as the gas washing bottle body, and the bottle cap 3 is configured as a PTFE screw cap that is universal for the same bottle body, with a built-in PTFE gasket to prevent gas leakage. The 50ml high borosilicate glass bottle also serves as a sample storage bottle.

[0034] In actual use, the ground gas is sent into the collection bottle 1 through the air inlet pipe 31. The ground gas is sent to the bottom of the collection bottle 1 along the end of the air inlet pipe 31 and reacts with the collecting agent.

[0035] Furthermore, the lower end of the air inlet pipe 31 is connected to a sand core bubbling head 7, which is a bubbler with multiple bubble-forming micropores 71 uniformly penetrating its exterior, so that the gas is dispersed and diffused into the collecting liquid only through the multiple bubble-forming micropores 71.

[0036] By setting a sand core bubbling head 7 with multiple bubbling micropores 71 penetrating its surface, the bubbles generated when gas is introduced into the liquid can be made smaller and more uniform, thereby effectively increasing the gas-liquid contact area.

[0037] Please see Figure 1 and Figure 4 It should be noted that the magnetic stirring mechanism includes a motor 23 and a magnet 24. The magnet 24 is connected to the output end of the motor 23 through a magnetic coupling. At the same time, the trapping bottle 1 contains a magnet 22, and the magnet 22 and the magnet 24 are attracted to each other magnetically.

[0038] The upper part of the frame 2 is a hollow cylindrical protrusion with a placement hole 21. The body of the collection bottle 1 can be placed into the placement hole 21 and thus loaded onto the frame 2. The magnet 24 is located in the placement hole 21 and corresponds to the magnet 22 vertically.

[0039] It should be noted that the magnet 22 is a cylindrical part, and its exterior is wrapped with an insulating layer to reduce contamination in the trap. The insulating layer is made of PTFE material and completely wraps the magnetic part. The magnet 24 is composed of four magnetic cylindrical parts, which are connected together. Two of the four cylindrical parts correspond to one end of the magnet 22, so that when the bottle is placed into the placement hole 21, the magnet 22 located in the bottle is attracted by the magnet 24.

[0040] The magnetic stirring mechanism also has a display screen 6 on the front, which is used to display the parameters of the motor 23.

[0041] It should be noted that the magnetic stirring mechanism has an adjustable speed. By using magnetic stirring to collect the liquid, the magnetic stirring and rotation can drive the liquid in the gas washing bottle to form a vortex, so that the gas and absorbent can fully contact each other, increase the effective contact area, and thus improve the dissolution or reaction rate of gas impurities.

[0042] It can also maintain the uniformity of liquid concentration. Stirring can prevent local concentration gradients caused by the absorbent being left to stand (such as excessively fast surface reaction or failure of the absorbent at the bottom), thus ensuring the overall activity of the absorbent.

[0043] Meanwhile, the liquid turbulence generated by stirring will shear the bubbles produced by the bubbler, making them smaller and more evenly distributed, thereby increasing the gas-liquid contact area and improving mass transfer efficiency.

[0044] Finally, it can suppress the formation of large bubbles to a certain extent. Stirring can destroy the tendency of bubbles to coalesce and reduce the problems of liquid splashing or insufficient gas-liquid contact time caused by the rapid rise of large bubbles.

[0045] In actual use, the drive motor 23 causes the magnet 24 to rotate, and the magnet 24 and the magnet 22 attract each other, so that the magnet 22 can be driven to rotate without contact inside the collection bottle 1, thereby stirring the solution inside the collection bottle 1.

[0046] It is understandable that the placement hole 21 is a stepped hole, and the body of the collection bottle 1 abuts against the stepped surface of the placement hole 21. This arrangement allows the magnet 24 located in the placement hole 21 and the bottle body to be fixed at intervals, thereby preventing the bottom of the collection bottle 1 from contacting the magnet 24.

[0047] In this embodiment, the collection bottle 1 is provided with a filter screen 9 inside. The filter screen 9 is an annular ring with a through hole in the middle. The inner and outer sides of the filter screen 9 are respectively connected to a first mounting ring 8 and a second mounting ring 81. The first mounting ring 8 abuts against the inner wall of the collection bottle 1, so that the magnetic spool 22 can be blocked from being poured out with the solution, and the magnetic spool 22 can be taken out through the through hole in the middle of the filter screen 9.

[0048] It should be noted that both the first mounting ring 8 and the second mounting ring 81 are made of PTFE material to reduce interference with the collection liquid. The first mounting ring 8 is fixed to the inner wall of the collection bottle 1 by its own elasticity. Before actual use, the position of the first mounting ring 8 can be easily changed.

[0049] Meanwhile, due to the setting of filter screen 9, the foam can be blocked by filter screen 9, thus increasing the residence time in the trap.

[0050] In order to fix the collection bottle 1 on the frame 2, the upper end of the frame 2 is provided with a mounting plate 4, and the mounting plate 4 is provided with at least one clip frame 5, and the collection bottle 1 is clipped into the clip frame 5.

[0051] The frame 5 is U-shaped, which allows the bottom end of the collection bottle 1 to be inserted into the placement hole 21 and the bottle body of the collection bottle 1 to be secured in the frame 5, thus setting the collection bottle 1 on the magnetic stirring mechanism 2.

[0052] Please see Figure 5 To facilitate the use of the frame 2 in the field, the bottom of the frame 2 is provided with a recessed receiving groove. Two ground stakes 25 are rotatably installed in the receiving groove. The ground stakes 25 can be rotated around the end connected to the receiving groove to a position that is vertical to the frame 2, so that the ground stakes 25 can be directly inserted into the soil to fix the frame 2 to the ground for use.

[0053] When using the ground gas nanoparticle collection device of this invention, ground gas is introduced into the collection bottle 1 through the air inlet pipe 31 on the bottle cap 3 by an air drill, filter and electric air pump. The ground gas enters the collection bottle 1 through the sand core bubbling head 7. Multiple bubbling micropores 71 on the sand core bubbling head 7 enable the ground gas to be evenly dispersed in the solution. Then, the drive motor 23 drives the magnet 24 to rotate through the magnetic coupling. Under the interaction of the magnetic field, the magnet 24 and the magnetic particle 22 transmit power without contact to drive the magnetic particle 22 to rotate, thereby stirring the solution in the collection bottle 1 and making the solution and ground gas fully mixed. Finally, when the solution in the collection bottle 1 needs to be analyzed for elemental content by high resolution inductively coupled plasma mass spectrometry (ICP-MS), the filter screen 9 can effectively block the magnetic particle 22 to prevent it from being poured out with the solution. When it is necessary to remove the magnetic particle 22, it can be done through the through hole in the middle of the filter screen 9.

[0054] In this document, the directional terms such as front, back, top, and bottom are defined based on the position of the components in the accompanying drawings and their relative positions to each other, solely for the purpose of clarity and convenience in expressing the technical solution. It should be understood that these are relative concepts and can vary depending on different methods of use and placement; the use of these directional terms should not limit the scope of protection claimed in this application.

[0055] Where there is no conflict, the above embodiments and features described herein can be combined with each other.

[0056] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
