Description

A SYSTEM FOR SAMPLE COLLECTION
FIELD OF THE INVENTION
The present invention generally relates to sampling technology and more particularly to a system for sample collection.
BACKGROUND OF THE INVENTION In the industry, manual sampling of liquid chemical substance has led to many accidents and near miss in the past. Spill over during the sampling is almost common. Due to present nature of manual sampling exposure of the operator to the chemical(s) is inevitable. The bad or non representative sampling are common causes of batch rejection, reprocessing and other quality related issues of the chemicals. It is the cause of lost profit. Safety may be compromised during the manual sampling. Whenever the chemical is under high temperature or at pressure, making it safe to open to take sample is also cause of worry and time consuming. Whenever the chemical storage is opened for sampling, breaking inert barrier, ingress of Air/Oxygen is inevitable, making it most dangerous. Time taken for the sampling is also very high due to the requirement of opening and closing of covers of storage.
As described above following are the main drawbacks of the current manual sampling technique: Operator Exposure or inhaling of the chemical during the manual sampling, poor operator safety records during manual sampling spill over of the chemicals during the manual sampling, poor product safety records during manual sampling, poor accuracy of the sampling quantity, poor quality of sampling, non-representative sample the exposure of the chemicals to atmosphere may degrade or change properties of the chemical itself and last but not the least environmental pollution. There is an eminent need in the art to overcome above disadvantages. Therefore, there is a need in the art for a system for sample collection.

As shown in figure 3A, the rotary actuator (116) is configured to line the cavity (114) with the second nozzle (108) thereby achieving a first position (201) of the cavity (114). As shown in figure 3A, the cavity (114) is in line with the second nozzle (108) and the first nozzle (107). The first nozzle (107) is connected with the container. Initially, the first valve may be closed. In an alternative or additional embodiment, the first nozzle (107) is connected with the container via the dip pipe.
Later, the second valve of the second nozzle (108)may be opened, and the source of compressed gas is configured to pump a fluid inside the cavity (114)being in the first position (201). The compressed gas may be pumped via a first hole (205) of the one or more holes through the second nozzle (108). The fluid may be an inert gas such as, but not limited to helium, radon, boron and like. Later, the first valve is opened. The compressed gas is adapted to push stagnant sample fluid lodged in the first nozzle (107). In an alternative or additional embodiment, the compressed gas is adapted to push stagnant sample fluid lodged in the dip pipe.
Next, the first nozzle (107), in connection with the container, is configured to draw the sample fluid inside the cavity (114) in line with the first nozzle (107), through a second hole (207) of the one or more holes. Since the sample fluid is pressurised, it rises up into the cavity (114) via first nozzle (107), the first valve through the inner nozzle (109)and thesecond hole (207) on its own. The dashed arrow shown in the figure 3A shows the flow of the sample fluid. After the sample fluid is drawn in the cavity (114), the inner valve and the first valveare closed to stop flow of the sample fluid.
Further, the rotary actuator (116) is configured to line the cavity (114) withthe third nozzle (110) thereby achieving a second position (202) of the cavity (114). As shown in figure 3B, the cavity (114) is in line with the third nozzle (110). After, the cavity (114) achieves the second position (202), the third valve of the third nozzle (110) is opened.As shown in figure 3, the sample bottle holder assembly (106) is configured to receive the sample fluid when the cavity (114) achieves the second position (202). The sample fluid may be flown into the sample collection bottle (113) of the sample bottle holder assembly (106) using gravity. The dashed arrow shown in the figure 3B shows the flow of the sample fluid. In an additional or alternative embodiment, the vent nozzle (111) disposed proximal to the sample bottle holder assembly (106) is configured to vent out the gas when the cavity (114) achieves the second position (202). The gas trapped in the dip pipe may be vented out through thew vent nozzle (111). The vent valve may open to remove the gas. The vent valve may close after the gas is removed. Further the level sensor in thesample bottle holder assembly (106) is configured to sense a level of the collected sample fluid. As soon as the sample fluid is filled up to a predetermined volume, the sample collection bottle (113) is detached from the sample bottle holder assembly (106) using the quick release (112). After the sample fluid is filled into the sample collection bottle (113) the third valve is closed to stop the flow of sample fluid into the sample collection bottle (113) to prevent the sample collection bottle (113) from overflowing.
In an alternative or additional embodiment, ones the sample fluid is emptied into the sample collection bottle (113), the rotary actuator (116) is configured to line the cavity (114) withthe second nozzle (108) thereby achieving thefirst position (201) of the cavity (114). Later, the second valve is opened to introduce the cleaning solution into the cavity (114). The cleaning solution may clean the cavity (114), the third nozzle (110) and the first nozzle (107) preparing them to draw a second batch of the sample fluid. After cleaning, the cavity is filled with the gas from the source of compressed gas via the second nozzle (108).
