Description

Technical Field

[0001] This utility model relates to the field of oil sampling technology, and in particular to a sampling device for oil production testing. Background Technology

[0002] Fats and oils are a general term encompassing both oils and fats. Generally, those that are liquid at room temperature are called oils, while those that are solid are called fats. Fats and oils can be derived from animals or plants, with animal fats generally being solid at room temperature, having good shortening properties, and being more commonly used.

[0003] Oils are unsaturated higher fatty acid glycerides, while fats are saturated higher fatty acid glycerides; both are higher fatty acid glycerides and are organic compounds. Vegetable oils are generally liquid at room temperature and pressure, hence the name "oil," while animal fats are solid at room temperature and pressure, hence the name "fat." Oils and fats are mixtures and do not have fixed melting or boiling points. Oils and fats are not only a major nutrient and staple food for humans, but also an important industrial raw material.

[0004] Chinese patent document CN220126249U discloses a sampling device for flavor liquid raw materials, including a dropper, graduation lines on the outer wall of the dropper, and a pressing head communicating with the dropper. Several moving rings are slidably connected to the outer wall of the dropper, and two symmetrically arranged grooves are formed on the outer wall of each moving ring. A clamp is slidably connected to the inner wall of each groove, and the adjacent side of each clamp abuts against the outer wall of the dropper. This flavor liquid raw material sampling device, by setting multiple moving rings and clamps on the outer wall of the dropper, allows for convenient and quick extraction of flavor liquid from the dropper when it is necessary to squeeze it out. Two moving rings separate the flavor liquid inside the dropper, and then another moving ring squeezes it out.

[0005] However, the equipment cannot sample materials at different depths in actual use, and its applicability is relatively poor. Utility Model Content

[0006] The main purpose of this utility model is to provide a sampling device for testing oil production, which can effectively solve the problem of relatively poor applicability.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] A sampling device for testing oil production includes an installation tube with an open top, a conical counterweight fixed at the lower end of the installation tube, a plurality of annular receiving tubes arranged vertically on the inner surface of the installation tube, an inlet on the inner wall of the annular receiving tube, an outlet tube communicating with the interior of the annular receiving tube fixed on the outer surface of the annular receiving tube, and the outlet tube penetrating through the installation tube, and a feeding assembly provided on the top surface of the inner cavity of the installation tube.

[0009] Preferably, the feeding assembly includes a sealing ring that slides within the inner cavity of the mounting tube. The upper end of the sealing ring has multiple through holes, and the lower end of the sealing ring is fixed with a spring. The inner ring of the sealing ring is threaded with a connecting rod, and the outer surface of the connecting rod is fixed with a notched sealing gasket for sealing the feed port.

[0010] Preferably, a bracket is fixed to the upper part of the inner surface of the through hole, a spring is fixed to the lower end of the bracket, and a sealing disc is fixed to the lower end of the spring.

[0011] Preferably, when the spring is in its natural state, the sealing disc seals the through hole.

[0012] Preferably, the notches of the plurality of sealing gaskets are staggered in the vertical direction.

[0013] Preferably, the sealing ring and the connecting rod are connected by a ball screw.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. This utility model adopts the design of a feeding assembly. Through the cooperation between the sealing ring and the connecting rod, the connecting rod will rotate when the equipment sinks. Then, through the cooperation between the sealing gasket and the feeding port, the equipment can sample grease at different depths, increasing the applicability of the equipment.

[0016] 2. This utility model adopts a spring and sealing disc design, which prevents grease from directly entering the inner ring of the annular collection tube, and prevents the equipment from starting to sample before reaching the specified depth, thus making the equipment more accurate in sampling.

[0017] 3. This utility model uses a ball screw to connect the sealing ring and the connecting rod, so that the connecting rod can rotate when the sealing ring moves up or down. At the same time, because grease has a lubricating effect, the connecting rod can rotate smoothly when the sealing ring moves down, making the equipment more stable during use.

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] like Figures 1-3 As shown, a sampling device for oil production testing includes an installation tube 1 with an open top. A conical counterweight 2 is fixed to the lower end of the installation tube 1. Due to the design of many cavities inside the installation tube 1, the conical counterweight 2 is needed to lower the center of gravity of the installation tube 1 so that the device can always remain vertically downward in the oil. Multiple annular receiving tubes 3 are vertically arrayed on the inner surface of the installation tube 1. The annular receiving tubes 3 are used to collect the sampled oil. The inner wall of the annular receiving tubes 3 has a feed inlet 4. The annular receiving tubes 3 are designed in annular shape. The device employs an internally designed inlet 4, allowing grease to continuously enter the annular receiving tube 3 through the inlet 4, thereby completing the grease sampling. The outer surface of the annular receiving tube 3 is also fixed with an outlet pipe 5 that communicates with its interior, and the outlet pipe 5 passes through the mounting tube 1. The outlet pipe 5 is existing technology. During equipment sampling, the outlet pipe 5 is in a closed state to prevent grease from entering the annular receiving tube 3 from the outlet pipe 5. After the equipment has completed sampling, the outlet pipe 5 is opened to remove the sample from the annular receiving tube 3. The top surface of the inner cavity of the mounting tube 1 is provided with a feeding assembly 6.

[0026] like Figure 4 and Figure 5 As shown, the feeding assembly 6 includes a sealing ring 61 that slides within the inner cavity of the mounting tube 1. The sealing ring 61 can only slide up and down within the mounting tube 1 and cannot rotate. A limiting block is used to prevent the sealing ring 61 from rotating (not shown in the figure). The upper end of the sealing ring 61 has multiple through holes 62, allowing grease to enter the inner ring of the annular receiving tube 3 through the through holes 62. A bracket 63 is fixed to the upper part of the inner surface of the through holes 62. A spring 66 is fixed to the lower end of the sealing ring 61. A connecting rod 67 is threaded to the inner ring of the sealing ring 61, so that when the sealing ring 61 moves downward, it can drive the connecting rod 67 to rotate. A notched sealing gasket 68 is fixed to the outer surface of the connecting rod 67 for sealing the feed port 4.

[0027] In addition, a spring 64 is fixed to the lower end of the bracket 63. The bracket 63 is used to install the spring 64. A sealing disc 65 is fixed to the lower end of the spring 64 to seal the through hole 62. When the spring 64 is in its natural state, the sealing disc 65 seals the through hole 62, preventing grease from directly entering the inner ring of the annular collection tube 3. This prevents the equipment from starting to sample before reaching the specified depth (when the equipment is placed in a bucket or pool, some grease will enter the inner ring of the annular collection tube 3. When the sealing gasket 68 does not seal the inlet 4, the grease will directly enter the inner cavity of the annular collection tube 3. At this time, the grease entering the inner cavity of the annular collection tube 3 is the upper layer of grease, which leads to inaccurate sampling). This allows the equipment to be more accurate when sampling.

[0028] The notches of multiple sealing gaskets 68 are staggered vertically, while the multiple feed inlets 4 are designed to be in a straight line vertically (due to the vertical placement of multiple annular receiving tubes 3, and combined with...). Figure 1 The discharge pipe 5 shows that the multiple annular receiving pipes 3 are not tilted, which can be inferred that the multiple inlets 4 are designed to be in a straight line in the vertical direction. This prevents the gaps of the multiple sealing gaskets 68 from coinciding with the inlets 4 at the same time (i.e., lubricating oil cannot enter different annular receiving pipes 3 through multiple inlets 4 at the same time). At the same time, the sampling volume can be increased by increasing the number of annular receiving pipes 3 and sealing gaskets 68 when the equipment is in use.

[0029] Furthermore, to ensure a smoother threaded connection between the sealing ring 61 and the connecting rod 67, a ball screw is used to connect them. This means that multiple balls are rotatably mounted on the inner ring of the sealing ring 61, and a threaded groove is formed on the outer surface of the connecting rod 67. This allows the connecting rod 67 to rotate when the sealing ring 61 moves upward or downward. Simultaneously, the lubricating effect of grease ensures smoother rotation of the connecting rod 67 when the sealing ring 61 moves downward, resulting in greater stability during operation.

[0030] The specific implementation method of this embodiment is as follows: When the oil is produced, the finished oil is first placed in a large barrel or pool, and then the oil in the large barrel or pool is separately filled. When the equipment is used, the installation tube 1 is first placed in the large barrel or pool containing the oil. Due to the design of the counterweight 2, the installation tube 1 will be placed vertically after being placed in the barrel or pool, and will gradually sink to the bottom under the action of gravity. At this time, it is necessary to ensure that there is no water or oil residue in the multiple ring collection tubes 3 to ensure the accuracy of sampling.

[0031] When the installation tube 1 is placed into the container of grease, since springs 66 and 64 are initially in their natural state, the sealing disc 65 seals the through hole 62 and the sealing ring 61 is at the top. Under the action of liquid pressure, the sealing disc 65 moves downward first, thus not sealing the through hole 62. Then, the grease enters the inner ring of multiple annular collection tubes 3 through the through hole 62. At this time, since only one sealing gasket 68 does not seal its corresponding inlet 4, the grease will enter the corresponding annular collection tube 3 through the unsealed inlet 4, thus completing the collection of grease at this depth.

[0032] When the pressure of the liquid pushes the sealing ring 61 downward, the connecting rod 67 rotates due to the interaction between the sealing ring 61 and the connecting rod 67. When the connecting rod 67 rotates, the notches of different sealing gaskets 68 correspond to the corresponding feed inlets 4, so that the corresponding sealing gaskets 68 do not seal the adjacent feed inlets 4. This allows grease to enter the annular collection tube 3 through the notches of the sealing gaskets 68, thus completing the grease collection. At the same time, the underwater pressure changes with the depth. Due to the downward movement of the sealing ring 61, different sealing gaskets 68 will not seal their corresponding feed inlets 4 at different depths, allowing grease at different depths to enter different annular collection tubes 3. This allows the equipment to perform stratified sampling of grease according to different depths during use.

[0033] Additionally, when the sealing disc 65 does not seal the through hole 62, if the sealing gasket 68 seals the corresponding inlet 4, the grease will flow into the inner ring of the annular receiving tube 3. When the sealing gasket 68 does not seal the corresponding inlet 4, the grease will enter the inner cavity of the corresponding annular receiving tube 3. At this time, the grease collected in the annular receiving tube 3 is the grease that entered the inner ring of the annular receiving tube 3 when the sealing disc 65 is opened. At the same time, the grease will continue to enter the inner ring of the annular receiving tube 3. When the next sealing gasket 68 does not seal the inlet 4, the grease that enters the annular receiving tube 3 is the grease in the inner ring of the annular receiving tube 3. This cycle repeats until all the annular receiving tubes 3 are filled.

[0034] It should be noted that the specific installation methods of the counterweight 2, the discharge pipe 5, and the sealing gasket 68 in this utility model are conventional designs and will not be described in detail in this utility model.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
