Description

Technical Field

[0001] This utility model relates to the field of petrochemical technology, and in particular to a novel oil-water sample collection container. Background Technology

[0002] In the analysis of crude oil and oilfield water, it is usually necessary to separate the collected oil and water samples. During the sampling operation of oil and water wells, according to the principles of fluid mechanics and thermodynamics, when the sampling valve is opened, the oil and water phases usually mix and flow out due to changes in pressure and temperature. However, since oil and water have low miscibility, they will simply separate into layers in the sampling container. In order to accurately carry out subsequent analysis, the oil and water samples must be separated to ensure the accuracy of the analysis results. This step is an important part of the oil and water sample pretreatment.

[0003] In traditional oil-water sample collection containers, since oil is less dense than water, it naturally floats on top while water settles at the bottom. Based on the principles of gravity separation and sedimentation, in order to obtain the water sample from the bottom layer, it is often necessary to pour out most or all of the oil sample from the top layer so that the water sample can be accessed and collected. This step is not only cumbersome, but the poured-out oil sample also needs to be specially collected and processed, which undoubtedly increases the workload and cost of the entire oil-water sample pretreatment process.

[0004] Furthermore, in the hazardous waste disposal process, traditional methods often require manually pouring out the oil from the sampling bottles after use, followed by compression and packaging. This is not only inefficient but also poses certain safety risks. Therefore, a new type of oil-water sample collection container is proposed for improvement. Utility Model Content

[0005] In order to overcome the defects of the prior art mentioned above, the inventors conducted in-depth research and, after a great deal of creative work, completed this utility model.

[0006] Specifically, the technical problem to be solved by this utility model is to provide a novel oil-water sample collection container to address the current problems of relatively cumbersome operation and low efficiency in hazardous waste treatment, which pose certain safety risks.

[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0008] A novel oil-water sample collection container includes a tank body, a drain hole on one side of the bottom of the tank body, a sealing groove at one end of the drain hole, and a snap-fit ​​mechanism for oil-water separation.

[0009] A sleeve is provided above the drain hole. The sleeve is fixedly fitted to the side wall of the tank. A slider is slidably connected to the inner wall of the sleeve. A rotary button is fixedly connected to one end of the slider. A connecting rod is fixedly connected to the inner wall of the slider groove. One end of the connecting rod passes through the inner wall of the sleeve and is fixedly connected to an L-shaped rod. A baffle is fixedly connected to the bottom end of the L-shaped rod. The baffle is slidably connected to the inner wall of the sealing groove. A rubber ring is fitted at the connection between the baffle and the sealing groove.

[0010] As an improved technical solution, a spring is sleeved on the outer surface of the connecting rod, one end of the spring is fixedly connected to the inner wall of the sleeve, and the other end of the spring is in contact with the inner wall of the slider groove.

[0011] As an improved technical solution, a latch is fixedly connected to the outer surface of the slider, a groove is formed on the outer surface of the sleeve, the latch is slidably connected to the inner wall of the groove, and a slot is also formed on the outer surface of the sleeve, which is connected to the groove.

[0012] As an improved technical solution, a liquid level observation window is fixedly installed on the other side of the tank, and a hollow cavity is opened inside the side wall of the tank.

[0013] As an improved technical solution, a tank neck is fixedly connected to the top of the tank body, and a groove is provided on the inner wall at the connection between the tank body and the tank neck.

[0014] As an improved technical solution, the bottom of the tank is fixedly connected to the bottom of the tank body, and the top of the tank neck is provided with a liquid inlet.

[0015] After adopting the above technical solution, the beneficial effects of this utility model are:

[0016] 1. In use, this utility model is based on the principle of gravity sedimentation. Under the action of gravity, the liquid will naturally settle. Since the density of water is greater than that of oil, water will accumulate at the bottom of the bottle. The opening of the drain hole is controlled by the snap-fit ​​mechanism to allow the aqueous phase to flow out. After a certain amount of liquid is obtained, the sampling of the lower aqueous phase can be stopped by controlling the closing of the drain hole by the snap-fit ​​mechanism. The whole process is simple to operate and has the functions of sample collection and oil-water sample separation, which improves the accuracy and reliability of sample collection and improves the efficiency of laboratory analysis.

[0017] 2. In the process of use, the groove design of this utility model reduces the thickness of the connection between the tank body and the tank neck, making it easier for the oil and water sample collection container to deform under mechanical compression during subsequent waste treatment. This facilitates packaging, avoids the tediousness and safety hazards of manual oil pouring, greatly improves processing efficiency, reduces safety issues caused by excessive pressure of the liquid inside the bottle during compression, ensures operational safety, and reduces environmental risks.

[0018] 3. During use, the liquid level observation window allows for a direct view of the oil-water separation. The hollow cavity design reduces the overall weight of the tank, making it easier to carry and operate. Furthermore, the hollow cavity provides insulation or buffering, protecting the sample inside the tank from external temperature changes. Attached Figure Description

Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0030] like Figure 1 and Figure 4 As shown in the figure, this embodiment provides a novel oil-water sample collection container, including a tank body 1, a drain hole 2 on one side of the bottom of the tank body 1, a sealing groove 21 at one end of the drain hole 2, and a snap-fit ​​mechanism 3 for oil-water separation.

[0031] A sleeve 31 is installed above the drain hole 2. The sleeve 31 is fixedly fitted onto the side wall of the tank body 1. A slider 33 is slidably connected to the inner wall of the sleeve 31. A rotary button 32 is fixedly connected to one end of the slider 33. A connecting rod 34 is fixedly connected to the inner wall of the slider 33. One end of the connecting rod 34 passes through the inner wall of the sleeve 31 and is fixedly connected to an L-shaped rod 35. A baffle 36 is fixedly connected to the bottom end of the L-shaped rod 35. The baffle 36 is slidably connected to the inner wall of the sealing groove 21. A rubber ring is fitted at the connection between the sealing groove 21 and the connecting rod 34. A spring 37 is fitted on the outer surface of the connecting rod 34. One end of the spring 37 is fixedly connected to the inner wall of the sleeve 31, and the other end of the spring 37 is in contact with the inner wall of the through groove of the slider 33. A latch 38 is fixedly connected to the outer surface of the slider 33. A sliding groove 39 is opened on the outer surface of the sleeve 31. The latch 38 is slidably connected to the inner wall of the sliding groove 39. A slot 310 is also opened on the outer surface of the sleeve 31, and the slot 310 is connected to the sliding groove 39.

[0032] Specifically, because oil is less dense than water, oil will naturally float on the top layer, while water will settle at the bottom layer. The sample in tank 1 will also exhibit this stratification.

[0033] After the collection is completed and before the drainage operation is performed, the drainage hole 2 is in a sealed state. At this time, the baffle 36 is tightly attached to the inner wall of the sealing groove 21 under the action of the spring 37, and the rubber ring at the connection between the baffle 36 and the sealing groove 21 further ensures good sealing performance and prevents the oil and water sample in the tank 1 from leaking.

[0034] When it is necessary to obtain a water sample from the lower layer, first press the rotary button 32. The rotary button 32 drives the slider 33 to slide on the inner wall of the sleeve 31. While the slider 33 moves, it compresses the spring 37 and drives the L-shaped rod 35 to move into the tank 1 through the connecting rod 34, thereby causing the baffle 36 to be pulled out from the sealing groove 21. At this time, the drain hole 2 is initially opened.

[0035] During the sliding of slider 33, latch 38 slides on the inner wall of groove 39. When latch 38 moves to one end of groove 39, rotary button 32 is rotated counterclockwise. At this time, rotary button 32 drives latch 38 to rotate through slider 33. On the one hand, latch 38 is engaged in groove 310. On the other hand, slider 33 drives baffle 36 to rotate within a range through connecting rod 34 and L-shaped rod 35, thereby further expanding the flow rate of drain hole 2 and fixing the position of baffle 36. After water sample collection is completed, rotary button 32 is rotated again. Under the elastic force of spring 37, slider 33 is reset and baffle 36 returns to sealing groove 21, completing the seal and preventing leakage of remaining oil and water samples.

[0036] This design is based on the principle of gravity sedimentation. Under the action of gravity, the liquid will naturally settle. Since the density of water is greater than that of oil, the water will accumulate at the bottom of the bottle. The opening of the drain hole 2 is controlled by the locking mechanism 3, allowing the aqueous phase to flow out. After a certain amount of liquid is obtained, the lower aqueous phase sampling can be stopped by closing the drain hole 2 through the locking mechanism 3. The whole process is simple to operate and has the functions of sample collection and oil-water sample separation, which improves the accuracy and reliability of sample collection and improves the efficiency of laboratory analysis.

[0037] In a further embodiment, a liquid level observation window 11 is fixedly installed on the other side of the tank body 1, a hollow cavity 12 is opened inside the side wall of the tank body 1, a tank neck 5 is fixedly connected to the top of the tank body 1, a groove 7 is opened on the inner wall at the connection between the tank body 1 and the tank neck 5, a tank bottom 4 is fixedly connected to the bottom of the tank body 1, and a liquid inlet 6 is opened at the top of the tank neck 5.

[0038] Specifically, the liquid level observation window 11 allows operators to easily observe the liquid level of the oil-water mixture in the tank 1 in real time, and also provides a direct view of the oil-water stratification. The hollow cavity 12 reduces the overall weight of the tank 1, making it easier to carry and operate. Furthermore, the hollow cavity 12 provides insulation or buffering, protecting the sample inside the tank 1 from external temperature changes. The groove 7 thins the connection between the tank 1 and the neck 5, allowing the oil-water sample collection container to deform more easily during mechanical compression in subsequent waste treatment processes. This facilitates packaging, avoids the tediousness and safety hazards of manual oil pouring, greatly improves processing efficiency, reduces safety issues caused by excessive pressure during compression, ensures operational safety, and lowers environmental risks.

Furthermore, it should be understood that after reading the technical description of this utility model, those skilled in the art can make various alterations, modifications, and / or variations to this utility model, and all such equivalent forms also fall within the scope of protection defined by the appended claims.
