Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of closed samplers, specifically a closed sampler with online cleaning function. Background Technology
[0002] Currently, when using the gas cylinder of the closed sampler, if it is necessary to observe the sample status, the material inside the gas cylinder needs to be poured into a beaker for observation. Since the material is volatile, pouring it into a beaker for observation will cause environmental pollution and allow operators to come into direct contact with the material. Doing this work for a long time will cause harm to the operator's health, thus defeating the original purpose of closed sampling.
[0003] Furthermore, during the gas cylinder sampling process, it is impossible to know the actual pressure inside the gas cylinder in real time. Sending the gas cylinder to the laboratory for analysis would pose a safety hazard and cause losses.
[0004] After prolonged use, the sampling cylinders become clogged due to the sudden slowdown in material flow and the presence of impurities in the samples. Furthermore, the sealed nature of the cylinders makes cleaning extremely inconvenient, and conventional cleaning methods are ineffective in removing impurities. Consequently, the data obtained from the samples are inaccurate. Therefore, there is an urgent need to design a sealed sampler with online cleaning capabilities to address these issues. Utility Model Content
[0005] The purpose of this invention is to provide a sealed sampler with online cleaning function, which solves the problems mentioned above, such as the inability to monitor the pressure inside the gas cylinder in real time and the inability to properly clean impurities inside the gas cylinder, resulting in inaccurate data.
[0006] To solve the above-mentioned technical problems, this utility model provides a sealed sampler with online cleaning function, including a baffle plate, a bottle body, and a first flushing pipe disposed at the bottom of the bottle body. The baffle plate is disposed in the bottle body, with its lower end connected to the inner bottom surface of the bottle body and its upper end forming a baffle gap with the inner top surface of the bottle body. The baffle plate divides the inner cavity of the bottle body into a first flushing chamber and a second flushing chamber. The baffle gap communicates with the first flushing chamber and the second flushing chamber, respectively. The first flushing chamber is connected to the first flushing pipe, which is equipped with a first flushing valve and a pressure pump. A pressure pipe passes through the bottle body and communicates with the inner cavity of the bottle body. A backflow pipe passes through the bottom of the bottle body and is disposed at the bottom of the second flushing chamber. The outlet ends of the pressure pipe and the backflow pipe are equipped with quick female connectors, and the quick female connectors are connected to spare pipes through quick male connectors.
[0007] Furthermore, the first flushing chamber has a structure that is narrow at the bottom and wide at the top, and the second flushing chamber has a structure that is narrow at the top and wide at the bottom.
[0008] Furthermore, the baffle plate is provided with a transition surface.
[0009] Furthermore, a pressure gauge is provided on the pressure pipeline, and needle valves are provided on both the pressure pipeline and the reflux pipeline.
[0010] Furthermore, the inlet end of the first flushing pipe is connected to the quick-connect female connector.
[0011] Furthermore, the backup pipeline is one of a sampling and analysis pipeline, a transport pipeline, or a circulation pipeline.
[0012] Furthermore, one end of the sampling and analysis pipeline is provided with a quick male connector and an analysis needle is provided thereon, and the other end of the analysis needle is equipped with a needle tip.
[0013] Furthermore, one end of the circulation pipe is provided with a quick male connector, and the other end of the circulation pipe is connected to the quick female connector of the first flushing pipe through the quick male connector.
[0014] Furthermore, a second flushing pipe is provided at the top of the bottle, and a second flushing valve is provided on the second flushing pipe.
[0015] The beneficial effects of this utility model are as follows: The arrangement of the first flushing pipe, the first flushing chamber, and the second flushing chamber, as well as their positional relationship, effectively allows the cleaning fluid sprayed from the first flushing pipe to flow through the baffle gap into the second flushing chamber under the obstruction of the top surface of the bottle. The baffle plate can create a relatively fast flow environment, thus effectively using only the first flushing pipe to flush the impurities in both the first and second flushing chambers. This allows the cylinder to achieve the purpose of cleaning impurities with a simple structure, reducing the cost of cleaning the sealed sampler. Furthermore, a backup pipe can be used to sample and analyze the sample in the cylinder or to circulate and transport the sample and cleaning fluid through a quick connection.
[0016] The internal structure of the first and second flushing chambers allows the cleaning fluid flowing upwards to spread out over a large area to meet the requirements of backflow, and at the same time allows the cleaning fluid flowing downwards to spread out over a large area from top to bottom to increase the force of the cleaning fluid, so as to better flush the impurities at the bottom away from the side wall and inner cavity of the cylinder, and transport them away from the cylinder through the backflow pipe.
[0017] The transition surface on the baffle plate allows the cleaning fluid in the lower cavity of the first flushing chamber to smoothly transition to the upper cavity without being blocked by the straight surface, effectively improving the efficiency of the baffle.
[0018] The installation of pressure gauges on the pressure pipeline can effectively monitor the pressure inside the bottle in real time, so as to ensure the pressure status of the sealed sampler during transportation or in various states.
[0019] The quick-connection setting of the backup pipeline enables the closed sampler to have both sampling and conveying / circulating functions, thereby improving the versatility of the closed sampler.
[0020] The second rinsing pipe at the top of the bottle allows for selection of whether rinsing is performed from the top or bottom of the bottle, depending on the situation. The fluid entering through the second rinsing pipe is diverted by the baffle plate to rinse the first and second rinsing chambers respectively, thereby working in conjunction with the first rinsing pipe to flush impurities out of the bottle and improve the cleanliness of the bottle.

Detailed Implementation
[0025] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and 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 protection scope of this utility model.
[0026] In one specific embodiment of this utility model, such as Figures 1-2 As shown, a closed sampler with online cleaning function is disclosed, including a baffle plate 1, a bottle body 2, and a first flushing pipe 3 disposed at the bottom of the bottle body 2. The baffle plate 1 is disposed inside the bottle body 2, with its lower end connected to the inner bottom surface of the bottle body 2 and its upper end forming a baffle gap with the inner top surface of the bottle body 2. The baffle plate 1 divides the inner cavity of the bottle body 2 into a first flushing chamber 21 and a second flushing chamber 22. The baffle gap is connected to the first flushing chamber 21 and the second flushing chamber 22, respectively. The first flushing chamber 21 is connected to the first flushing pipe 3. The first flushing pipe 3 is equipped with a first flushing valve 12 and a pressure pump. A pressure pipe 4 is installed on the bottle body 2 and is connected to the inner cavity of the bottle body 2. A backflow pipe 5 is installed at the bottom of the bottle body 2 and is installed at the bottom of the second flushing chamber 22. The outlet ends of the pressure pipe 4 and the backflow pipe 5 are both equipped with quick female connectors 61. The quick female connector 61 is connected to a spare pipe 7 through a quick male connector 62.
[0027] The first flushing chamber 21 has a structure that is narrow at the bottom and wide at the top, and the second flushing chamber 22 has a structure that is narrow at the top and wide at the bottom. The internal structure of the first flushing chamber 21 and the second flushing chamber 22 can allow the cleaning fluid flowing upward to spread out over a large area to achieve the requirement of backflow, and at the same time allow the cleaning fluid flowing downward to spread out over a large area from top to bottom to increase the flushing force of the cleaning fluid, so as to better flush the impurities at the bottom away from the side wall and inner cavity of the cylinder, and transport them away from the cylinder through the backflow pipe 5.
[0028] The baffle plate 1 is provided with a transition surface 11. The transition surface 11 on the baffle plate 1 can allow the cleaning fluid in the lower cavity of the first flushing chamber 21 to smoothly transition to the upper cavity without being blocked by the straight surface, which effectively improves the efficiency of the baffle.
[0029] Pressure gauge 8 is installed on pressure pipeline 4, and needle valve 9 is installed on both pressure pipeline 4 and backflow pipeline 5. The pressure gauge 8 on pressure pipeline 4 can effectively monitor the pressure inside bottle 2 in real time, so as to ensure the pressure of the sealed sampler during transportation or in various states, and prevent safety hazards caused by unstable pressure inside the sealed sampler.
[0030] The inlet end of the first flushing pipe 3 is connected to a quick-connect female connector 61.
[0031] The backup pipeline 7 is one of the sampling and analysis pipeline, the conveying pipeline, or the circulation pipeline. The quick-connect setting of the backup pipeline 7 allows the closed sampler to have the functions of conveying and circulating while it has the functions of sampling, thereby improving the versatility of the closed sampler.
[0032] One end of the sampling and analysis pipeline is equipped with a quick male connector 62, and an analysis needle 71 is mounted on it. The other end of the analysis needle 71 is equipped with a needle tip 72.
[0033] One end of the circulation pipe is equipped with a quick male connector 62, and the other end of the circulation pipe is connected to the quick female connector 61 of the first flushing pipe 3 through the quick male connector 62.
[0034] The top of the bottle body 2 is provided with a second rinsing pipe 13, and the second rinsing pipe 13 is provided with a second rinsing valve 14. The setting of the second rinsing pipe 13 at the top of the bottle body 2 can be selected to rinse from the top or bottom of the bottle body 2 according to the situation. The fluid entering the second rinsing pipe 13 is divided by the baffle plate 1 to rinse the first rinsing chamber 21 and the second rinsing chamber 22 respectively. In this way, it can cooperate with the first rinsing pipe 3 to flush the impurities in the bottle body 2 away from the bottle body 2, thereby improving the cleanliness of the bottle body 2.
[0035] The arrangement of the first flushing pipe 3, the first flushing chamber 21, and the second flushing chamber 22, as well as their positional relationship, of this utility model can effectively allow the cleaning fluid sprayed from the first flushing pipe 3 to be deflected through the baffle gap into the second flushing chamber 22 under the obstruction of the top surface inside the bottle body 2. This allows for the effective flushing of impurities in both the first flushing chamber 21 and the second flushing chamber 22 using only the first flushing pipe 3. This enables the cylinder to achieve the purpose of thoroughly cleaning impurities inside the bottle body 2 with a simple structure, thereby reducing the cost of cleaning the sealed sampler. Furthermore, a spare pipe 7 is used to sample and analyze the sample inside the cylinder or to circulate and transport the sample and cleaning fluid through a quick connection.
[0036] The working process of this utility model is as follows:
[0037] After the quick-connect female connector 61 at the end of the pressure pipe 4 is aligned with the quick-connect male connector on the production equipment, the needle valve 9 on the pressure pipe 4 is opened, allowing the material in the production equipment to be transported from the pressure pipe 4 to the closed sampler. At the same time, the pressure of the transported material can be observed in real time through the pressure gauge 8, so as to adjust the opening of the needle valve 9. After a certain amount of sample is taken into the closed sampler, the needle valve 9 on the pressure pipe 4 is closed to disconnect the sampling. The sample taken into the closed sampler is dispersed from the top of the bottle 2 into the first rinsing chamber 21 and the second rinsing chamber 22. Due to the structural design of the first rinsing chamber 21, which is narrow at the bottom and wide at the top, a larger amount of sample is diverted into the first rinsing chamber 21.
[0038] When it is necessary to sample and analyze the sample, connect the quick male connector 62 of the sampling and analysis pipeline to the quick female connector 61 on the reflux pipeline 5, and open the needle valve 9 on the reflux pipeline 5. The analysis needle 71 will then draw a portion of the sample. After the drawing is completed, close the needle valve 9 and transfer the sample to the test dish through the needle tip 72 to prevent personnel from directly contacting the sample.
[0039] If impurities accumulate in bottle 2 after prolonged sampling, it is necessary to rinse the impurities inside bottle 2. Depending on the condition of the impurities in bottle 2, the choice should be made between introducing the cleaning solution through the first rinsing pipe 3 or the second rinsing pipe 13.
[0040] When the cleaning fluid is introduced through the second flushing pipe 13, the quick-connect female connector 61 at the inlet end of the first flushing pipe 3 is connected to a pipe. One end of the pipe is connected to a quick-connect male connector, and the other end is connected to a water tank. The quick-connect male connector is connected to the quick-connect female connector 61 at the inlet end of the first flushing pipe 3, and the first flushing valve 12 on the first flushing pipe 3 is opened. The cleaning fluid in the water tank is pressurized to a certain pressure by the pressure pump on the first flushing pipe 3, and then flushed through the first flushing pipe 3 into the first flushing chamber 21 to remove impurities in the first flushing chamber 21. The cleaning fluid spreads out at the top under the flushing force to flush the wider part of the first flushing chamber 21. The flushing force reaches the inner top surface of the bottle body 2. After being blocked and deflected, the cleaning fluid is sprayed into the second flushing chamber 22 through the deflection gap, so that the cleaning fluid enters from the narrow opening at the top of the second flushing chamber 22 and flows downward over a large area, which can effectively remove impurities in the second flushing chamber 22. A delivery pipe is quickly connected to the quick-connect female connector 61 at the outlet end of the backflow pipe 5, and the needle valve 9 on the backflow pipe 5 is opened to discharge the flushed dirty fluid from the delivery pipe. When the dirty fluid is almost completely discharged, a circulation pipe can be quickly connected to the quick-connect female connector 61 at the outlet end of the backflow pipe 5. The circulation pipe circulates the cleaning fluid into the first flushing pipe 3, and the cleaning fluid is pressurized by the pressure pump into the bottle 2 until the impurities in the bottle 2 are completely removed.
[0041] When the inner cavity at the top of bottle 2 is severely clogged with impurities, the quick-connect female connector 61 at the inlet end of the second flushing pipe 13 is connected to a pipe. One end of the pipe is connected to a quick-connect male connector, and the other end is connected to a water tank. The quick-connect male connector is connected to the quick-connect female connector 61 at the inlet end of the second flushing pipe 13, and the second flushing valve 14 on the second flushing pipe 13 is opened. The pressure pump connected to the pipe and the water tank are pressurized to a certain pressure by the pressure pump. Then, the cleaning liquid is sent into bottle 2 through the second flushing pipe 13. Under the diversion of the baffle plate, the first flushing chamber 21 and the second flushing chamber 22 are flushed respectively, and the impurities in bottle 2 are flushed away from bottle 2.
[0042] The above-disclosed embodiment is merely a preferred embodiment of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
