Description

Technical Field

[0001] This utility model relates to the field of sample digestion technology, and more specifically, to an environmental sample digestion device. Background Technology

[0002] Digestion is a common sample pretreatment method. Based on the degree of automation, it can be divided into semi-automatic and fully automatic digesters; based on the principle, it can be divided into electrothermal digesters and microwave digesters. Both have relatively mature products and are widely used. An electrothermal digester includes a heating element, which is connected to an AC power supply through a main heating circuit to form a heating loop. The main heating circuit includes an air circuit breaker, a single-phase full-bridge rectifier and filter unit, and a Buck main circuit connected in series. It also includes a temperature sensor mounted on the heating element. The temperature sensor is connected to a microcontroller and a PWM control drive unit through a filter and amplification unit. The microcontroller is connected to the PWM control drive unit, which is connected to the Buck main circuit through an isolation drive unit. The PWM control drive unit samples the current in the heating loop through a sampling resistor. The microcontroller's output is connected to a temperature display device, and its input is connected to a parameter setting device.

[0003] Currently, digestion apparatus is a commonly used sample pretreatment device. Existing digestion devices can only store samples in storage tubes of a specified size. This leads to instability when dealing with storage tubes of different heights or diameters, resulting in poor flexibility and affecting the effectiveness of the device. Therefore, it is necessary to propose an environmental sample digestion device to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an environmental sample digestion device, which aims to improve the existing digestion devices that can only store samples in storage tubes of a specified size. This leads to unstable placement when dealing with storage tubes of different heights or diameters, resulting in poor flexibility and affecting the effectiveness of the device.

[0005] This utility model is implemented as follows:

[0006] This utility model provides an environmental sample digestion device, including a digestion structure and a digestion storage structure.

[0007] The digestion structure includes a digester body and a support member.

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Example

[0023] Please see Figures 1-5 This utility model provides a technical solution: an environmental sample digestion device, including a digestion structure 100 and a digestion storage structure 200.

[0024] Please see Figure 1 and Figure 2 The digestion structure 100 includes a digester body 110 and a support member 130. The digester body 110 has a door 120 hinged to its surface, and the support member 130 is fixed to the bottom of the digester body 110.

[0025] An observation transparent plate 121 is embedded inside the instrument door 120, and a handle 122 is installed on one side of the instrument door 120. The observation transparent plate 121 is used to observe the digestion inside the digestion apparatus body 110, and the handle 122 can easily open or close the instrument door 120. Support members 130 are symmetrically distributed at the bottom of the digestion apparatus body 110. The support member 130 includes a support column 131 and a pad 132. The support column 131 is fixed to the bottom of the digestion apparatus body 110, and the pad 132 is fixed to the support column 131. Here, the support member 130 is used to keep the digestion apparatus body 110 away from the ground.

[0026] Please see Figures 1-5The digestion and storage structure 200 includes a tray 210, a support plate 220, a clamping telescopic member 240, and an adjusting member 250. The tray 210 is installed inside the digester body 110. A groove 211 is provided on the top surface of the tray 210. A through hole 221 is provided inside the support plate 220. Sliding grooves 212 are provided on both sides of the groove 211 and the through hole 221. An elastic member 230 is installed inside the sliding groove 212. The clamping telescopic member 240 is fixed on the elastic member 230. An adjusting member 250 is installed between the tray 210 and the support plate 220.

[0027] The elastic element 230 includes a movable rod 231 and a spring 233. One end of the movable rod 231 is fixed with a sliding plate 232, which is slidably connected to the inside of the groove 212. One end of the spring 233 is fixed to the sliding plate 232, and the other end of the spring 233 is fixed to the inner surface of the groove 212. The elastic element 230 is used to clamp and fix the sample storage tube, thereby facilitating the handling of storage tubes of different diameters.

[0028] The clamping telescopic component 240 includes a clamping support plate 241 and a clamping plate 242. The clamping support plate 241 and the clamping plate 242 are respectively fixed to the movable rod 231. A slot 244 is provided on one side of the clamping support plate 241. An insert plate 243 is fixed at the bottom of the clamping plate 242. The insert plate 243 is slidably inserted into the inside of the slot 244. The slot 244 and the insert plate 243 have matching trapezoidal cross sections. A limiting block 2431 is fixed on one side of the insert plate 243. The slot 244 has a limiting groove 2441 that matches the limiting block 2431. The limiting block 2431 is slidably connected to the inside of the limiting groove 2441. Here, the clamping telescopic member 240 can conveniently limit the support plate 220, thereby improving the stability of the support plate 220's lifting and lowering. At the same time, the vertical extension and retraction of the clamping plate 242 can better cope with the storage of sample tubes at different heights, which is conducive to improving the stability of digestion. Meanwhile, the limiting block 2431 has a certain limiting function to prevent the insert plate 243 from dislodging from the slot 244.

[0029] The adjusting component 250 includes a threaded rod 251 and an internally threaded tube 253. The threaded rod 251 rotates through the support plate 220. One end of the threaded rod 251 is keyed to a knob 252. The internally threaded tube 253 is fixed to the support plate 210. The other end of the threaded rod 251 is threaded into the interior of the internally threaded tube 253. By rotating the threaded rod 251 through the knob 252, the threaded rod 251 can drive the support plate 220 to move upward, causing the clamping plate 242 to extend upward, thereby clamping the sample storage tube over a longer distance and keeping it stable.

[0030] Specifically, the working principle of this environmental sample digestion device is as follows: During use, the threaded rod 251 can be rotated by knob 252 according to the length of the sample storage tube, causing the threaded rod 251 to drive the support plate 220 to move upward. At this time, the clamping plate 242 will extend upward under the action of the insert plate 243. After moving to the appropriate position, the storage tube containing the sample is inserted into the corresponding through hole 221 and positioned between the clamping plates 242. At this time, the storage tube can be clamped and fixed under the elastic action of the spring 233. Then, the instrument door 120 is closed, and the digestion instrument body 110 drives the digestion storage structure 200 to rotate to perform the digestion operation. This is beneficial for handling storage tubes of different diameters and heights during use, making the storage tube more stable during digestion, and also improving the flexibility and convenience of use.

[0031] It should be noted that the specific model and specifications of the digester body 110 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0032] The power supply and principle of the digester body 110 are clear to those skilled in the art and will not be described in detail here.

[0033] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
