Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of closed sample storage, in particular to a closed sample storage device with a retention type sample feeding structure. Background Art
[0002] The closed sample storage device is mainly used for sampling. Due to its closed sampling method, it can maintain the integrity of the sample. This device can prevent the sample from being contaminated or the composition is changed during the sampling process. It also reduces the possibility of sample volatilization and contamination, making the test analysis more accurate and reliable. When using a closed sample storage device to sample the sample in the storage container, its input end is generally connected to the output end of the sample storage container, and then the sample inside the sample storage container is sampled, and then the sample is stored in the sampling bottle.
[0003] However, when the closed sample storage device is in use, the sample extracted from the sample storage container needs to be promptly introduced into the relevant structure of the analysis and detection system for analysis and detection, because the internal structure of the closed sample storage device does not have the function of retaining samples for a long time, and the sample needs to be transported or transferred to a container during the analysis and detection process. In this process, the sample may be contaminated, resulting in the purity of the sample being affected, which in turn affects the detection results. If the test data differ greatly, multiple batches of comparative experiments need to be carried out. When sampling again, the sample is not in the same time period as the previously sampled sample, which affects the test data in terms of sampling time. In addition, the sampling process of using the closed sample storage device multiple times is time-consuming and labor-intensive.
[0004] Based on the above situation, it is necessary to design a closed sample storage device with a retention type sample injection structure to solve the above problems. Utility Model Content

DETAILED DESCRIPTION
[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below with reference to specific illustrations.
[0024] Reference Figures 1-6 As shown, a closed sample storage device with a retention type sampling structure includes a sampling tube 1 connected to the output end of the closed sample storage device (i.e., the sampling port of the closed sample storage device) and provided with two output ends, and a box 2 movably installed inside the closed sample storage device. The above-mentioned closed sample storage device (not shown in the figure) is a prior art device, and its main function is to obtain samples in a closed environment and ensure that the samples are not contaminated by the outside world during the sampling process. The operator connects the sampler to the medium to be sampled (such as liquid) by operating the valve 17 or interface on the sampler, and extracts the sample from the process pipeline or container into the sampler through the sampling port or sampling tube 1 on the sampler. One of the output ends of the sampling tube 1 is used for normal sampling.
[0025] The other output end of the sampling tube 1 is connected to a branch pipe 4. In order to provide a storage container for the collected samples in the sealed sample storage device, a tank body 3 is provided inside the box body 2. The output end of the branch pipe 4 is connected to the input end of the tank body 3 through a connector 5. This makes it convenient to load samples into the tank body 3 while using the sampling tube 1 for sampling operations. A valve 17 is provided on the sampling tube 1, which can control the connectivity between the two output ends of the sampling tube 1. In order to ensure the stability of the environment when the sample is retained and to ensure that the quality of the sample does not change due to changes in the environment, a detection component for detecting the internal temperature of the box body 2 and a heat-conducting component for controlling the internal temperature of the box body 2 are provided on the box body 2, and the heat-conducting component and the detection component are electrically connected.
[0026] Among them, reference Figure 1-3 As shown, the detection component includes a controller 7 and a temperature sensor 6 connected to the inside of the box 2. The temperature sensor 6 is used to detect the temperature inside the box 2. The input end of the controller 7 is connected to the output end of the temperature sensor 6 and receives the temperature detection signal of the temperature sensor 6. The output end of the controller 7 is connected to the heat conduction component. The output end of the controller 7 outputs a control signal for controlling the operation of the heat conduction component. The operator can observe the real-time temperature inside the box 2 on the controller 7, and then adjust the heat conduction component according to this data to adjust the temperature change inside the box 2.
[0027] The tank body 3 is movably installed inside the box body 2. According to actual usage, when the tank body 3 needs to be taken out, the tank body 3 needs to be removed from the box body 2, and the separate tank body 3 requires its own closed structure. The structure is that the input end and output end of the tank body 3 are respectively provided with a solenoid valve 13 and a manual valve 14, both of which control the sealing inside the tank body 3. The input end of the solenoid valve 13 is connected to the output end of the controller 7, and the output end of the controller 7 outputs a control signal for controlling the operation of the solenoid valve 13. A pressure sensor 18 is provided on the tank body 3. The pressure sensor 18 is used to monitor the pressure inside the tank body 3 at all times and prevent pressure leakage caused by damage to the tank body 3. The operator can also turn the multi-way valve 12 to the input end of the next tank body 3 to be loaded according to actual conditions, and then continue the above operation.
[0028] There are several output ends of the branch pipe 4, and a multi-way valve 12 is provided on the output end of the branch pipe 4. The multi-way valve 12 is an electromagnetic multi-way valve 12, which can be controlled by an electric component. In order to be able to save multiple copies when collecting samples, there are several tank bodies 3 inside the box body 2, and the input ends of several tank bodies 3 are respectively connected to the several output ends of the branch pipe 4. By controlling the multi-way valve 12, one of the output ends of the branch pipe 4 is connected to the input end of the tank body 3. At this time, the sample flowing inside the branch pipe 4 will be introduced into the tank body 3, and the multi-way valve 12 is connected to the controller 7 in the detection component. The operator controls the controller 7. The output end of the controller 7 outputs a control signal, and the control signal controls the operation of the multi-way valve 12, thereby controlling one of the several output ends of the branch pipe 4 to be connected with the input end of one of the several tank bodies 3. When the controller 7 controls the multi-way valve 12 to be connected with one of the tank bodies 3, the controller 7 will then control the solenoid valve 13 on the connected tank body 3 to operate and open, so that the collected sample can be smoothly introduced from the branch pipe 4 into the interior of the tank body 3. After the sample is placed in a certain position inside the tank body 3, the controller 7 controls the multi-way valve 12 to close, and then controls the solenoid valve 13 to close.
[0029] When the multi-way valve 12 connects one of the output ends of the branch pipe 4 with the input end of the tank 3 .
[0030] Reference Figure 4As shown, further, the above-mentioned heat conduction component includes a serpentine pipe fitting 8 connected to the inner wall of the box body 2 and a water pump 9 connected to the serpentine pipe fitting 8. The serpentine pipe fitting 8 is used to receive a liquid medium with a specific temperature. The liquid medium is a prior art solution and can be water or an inorganic salt solution. According to needs, a specific type of liquid is used as a heat transfer medium to keep the heat on and around the serpentine pipe fitting 8 at the same temperature as the liquid medium. The water pump 9 provides power for the circulation of the liquid medium inside the serpentine pipe fitting 8. The serpentine pipe fitting 8 is provided with fins 10 that increase its own heat conduction area. When the temperature sensor 6 senses a large temperature change inside the box body 2, a liquid medium of corresponding temperature is introduced into the serpentine pipe fitting 8. Under the drive of the water pump 9, the liquid medium flows inside the serpentine pipe fitting 8, and the heat on and around the serpentine pipe fitting 8 is kept at the same temperature as the liquid medium, thereby controlling the temperature inside the box body 2.
[0031] In order to make better use of the serpentine pipe fitting 8, the heat conduction component also includes a cooling fan 11 arranged on the box body 2. The air outlet end of the cooling fan 11 corresponds to the position of the serpentine pipe fitting 8. Under the blowing of the cooling fan 11, the temperature inside the box body 2 can be better changed. The cooling fan 11 and the water pump 9 are both connected to the output end of the controller 7. After the controller 7 receives the temperature detection signal of the temperature sensor 6, the output end outputs the control signal for controlling the operation of the cooling fan 11 and the water pump 9. After receiving the temperature signal of the temperature sensor 6, the controller 7 controls the operating power of the cooling fan 11 and the water pump 9 according to the strength of the signal, thereby regulating the temperature inside the box body 2.
[0032] Reference Figure 6 As shown, finally, because the box body 2 is movably installed on the closed sample storage device, during installation, in order to better connect the tank body 3 inside the box body 2 with the branch pipe 4, a connector 5 is provided, and the connector 5 is connected to the output end of the branch pipe 4. The connector 5 is a tubular structure, and is sealed and slidably connected to the output end of the branch pipe 4, and can be sealed and rotated. A threaded portion 15 is provided on the outer wall of the pipe at the input end of the tank body 3, and a threaded portion 2 16 is provided on the inner wall of the end of the connector 5 away from the branch pipe 4, and the threaded portion 15 and the threaded portion 2 16 are movably connected. When in use, after connecting the pipe on the input end of the tank body 3 with the output end of the branch pipe 4, move the end of the connector 5 that drives the threaded portion 2 16 to the position corresponding to the threaded portion 15 on the input end of the tank body 3, and then rotate the connector 5, and the threaded portion 15 and the threaded portion 2 16 are threadedly connected, so that the input end of the tank body 3 and the output end of the branch pipe 4 can be sealed.
