Abstract
Description
Technical Field
[0001] This utility model belongs to the field of petrochemical technology, and in particular to a sampling device for petrochemical applications. Background Technology
[0002] Petrochemicals generally refer to the petrochemical industry, which is an important part of the chemical industry. Petrochemicals refer to the processing industry that uses petroleum and natural gas as raw materials to produce petroleum products and petrochemical products. It mainly includes various fuel oils (gasoline, kerosene, diesel, etc.) and lubricating oils, as well as liquefied petroleum gas, petroleum coke, paraffin wax, asphalt, etc. Sampling and testing are required during the production process of petrochemicals.
[0003] Existing petrochemical sampling devices mostly involve inserting the sampling tube directly into the oil well to sample the oil. This sampling method inevitably results in a large amount of oil adhering to the side wall of the sampling tube. Therefore, after the sampling tube is removed, it needs to be wiped manually to prevent it from dripping onto the ground and causing pollution. However, manual wiping is easy to get on your hands and is quite tedious. Therefore, there is an urgent need for a petrochemical sampling device to solve this problem. Utility Model Content
[0004] The purpose of this invention is to provide a sampling device for petrochemical applications to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a sampling device for petrochemical applications, comprising a sampling storage box for the sampling device, a sampling cylinder fixedly connected to the lower end of the storage box, a sampling pump fixedly installed on the top surface of the storage box, an extension rod fixedly connected to the top surface of the storage box, an mounting plate slidably sleeved on the side wall of the extension rod, a crossbar fixedly connected to the top surface of the extension rod, an mounting ring slidably sleeved on the side wall of the sampling cylinder, a funnel-shaped sealing ring fixedly connected to the lower end of the mounting ring, and the diameter of the mounting ring being larger than the diameter of the funnel-shaped sealing ring, the funnel-shaped sealing ring slidably sleeved on the side wall of the sampling cylinder, and the small opening of the funnel-shaped sealing ring tightly fitting against the outer wall of the sampling cylinder, vertical rods symmetrically fixedly connected to the top surface of the mounting ring, the upper end of the vertical rods extending through to the top of the mounting plate, and an arc-shaped plate fixedly connected between the top surfaces of the two vertical rods.
[0006] Preferably, a funnel-shaped ring is slidably sleeved on the side wall of the funnel-shaped sealing ring, and mounting blocks are symmetrically fixedly connected to the side wall of the funnel-shaped ring.
[0007] Preferably, the top surface of the mounting block is symmetrically and fixedly connected with vertical plates, and a limit cylinder is rotatably connected between the two vertical plates.
[0008] Preferably, a telescopic rod is slidably connected inside the limiting cylinder, and the top surface of the telescopic rod is fixedly connected to the lower end of the mounting ring.
[0009] Preferably, a tension spring is fixedly connected inside the limiting cylinder, and the top surface of the tension spring is fixedly connected to the lower end of the telescopic rod.
[0010] Preferably, the inner wall of the limiting cylinder is symmetrically provided with limiting grooves, and the side wall of the telescopic rod is symmetrically fixedly connected with limiting blocks.
[0011] Preferably, the two limiting blocks on the side wall of the telescopic rod are slidably connected to the inside of the two limiting grooves opened in the inner wall of the limiting cylinder.
[0012] Compared with the prior art, the technical effects and advantages of this utility model are as follows:
[0013] This petrochemical sampling device, when sampling oil from an oil well, first involves holding a horizontal bar and placing the storage box and sampling cylinder into the well, immersing the sampling cylinder in the oil. Then, the sampling pump is activated to draw oil through the sampling cylinder into the storage box. The sampling cylinder is then removed. To remove oil adhering to the side wall of the sampling cylinder, the arc-shaped plate is held to press the vertical rod downwards. The vertical rod then moves the mounting ring downwards, which in turn moves the funnel-shaped sealing ring fixedly connected to its lower end downwards along the outer wall of the sampling cylinder, thus scraping away the oil adhering to the side wall. Compared to existing technologies, this device effectively scrapes away oil adhering to the side wall of the sampling cylinder, eliminating the need for manual cleaning and increasing its practicality.

[0021] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.
[0022] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.
[0023] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.
[0024] In order to, as Figures 1 to 4The main structure of the device shown is as follows: a storage box 1, a sampling cylinder 2 fixedly connected to the lower end of the storage box 1, a feed hole on the side wall of the sampling cylinder 2, and a tapered lower end to facilitate the retention of oil adhering to the side wall of the sampling cylinder 2; a sampling pump 3 fixedly installed on the top surface of the storage box 1; an extension rod 4 fixedly connected to the top surface of the storage box 1; a mounting plate 5 slidably sleeved on the side wall of the extension rod 4; a crossbar 6 fixedly connected to the top surface of the extension rod 4; a mounting ring 7 slidably sleeved on the side wall of the sampling cylinder 2; a funnel-shaped sealing ring 8 fixedly connected to the lower end of the mounting ring 7, with the diameter of the mounting ring 7 being larger than the diameter of the funnel-shaped sealing ring 8; the funnel-shaped sealing ring 8 slidably sleeved on the side wall of the sampling cylinder 2, with the small opening of the funnel-shaped sealing ring 8 tightly fitted to the outer wall of the sampling cylinder 2; and a funnel-shaped ring 11 slidably sleeved on the side wall of the funnel-shaped sealing ring 8. A mounting block 12 is symmetrically fixedly connected to the side wall of the funnel-shaped ring 11. A vertical plate is symmetrically fixedly connected to the top surface of the mounting block 12. A limiting cylinder 13 is rotatably connected between the two vertical plates. A telescopic rod 14 is slidably connected inside the limiting cylinder 13. The top surface of the telescopic rod 14 is fixedly connected to the lower end of the mounting ring 7. A tension spring 15 is fixedly connected inside the limiting cylinder 13. The top surface of the tension spring 15 is fixedly connected to the lower end of the telescopic rod 14. Thanks to the fact that the funnel-shaped ring 11 and the funnel-shaped sealing ring 8 are set with the same shape, the funnel-shaped ring 11 squeezes the funnel-shaped sealing ring 8, thereby making the funnel-shaped sealing ring 8 fit tightly against the outer wall of the sampling cylinder 2, thereby increasing the cleaning effect. A vertical rod 9 is symmetrically fixedly connected to the top surface of the mounting ring 7. The upper end of the vertical rod 9 extends through to the top of the mounting plate 5. An arc plate 10 is fixedly connected between the top surfaces of the two vertical rods 9.
[0025] The inner wall of the limiting cylinder 13 is symmetrically provided with limiting grooves, and the side wall of the telescopic rod 14 is symmetrically fixedly connected with limiting blocks 16. The two limiting blocks 16 on the side wall of the telescopic rod 14 are slidably connected to the inside of the two limiting grooves provided in the inner wall of the limiting cylinder 13. The two limiting blocks 16 can effectively limit the sliding direction of the telescopic rod 14.
[0026] All of them are set to existing technology, and their working principles, dimensions and models are irrelevant to the functions of this application, so they will not be described in detail. All of them are controlled by remote control switches.
[0027] Working principle
[0028] In use, this petrochemical sampling device involves first holding the horizontal bar 6 and placing the storage box 1 and sampling cylinder 2, which are fixedly connected to it, into the oil well, immersing the sampling cylinder 2 in the oil. Then, the sampling pump 3, fixedly connected to the top of the storage box 1, is activated to draw oil through the sampling cylinder 2 into the storage box 1. The sampling cylinder 2 is then removed. When it is necessary to remove oil adhering to the side wall of the sampling cylinder 2, the arc-shaped plate 10 is first held to press down the two vertical bars 9, which are fixedly connected to it. The vertical bars 9 then move the mounting ring 7, which is fixedly connected to it, downwards, and the mounting ring 7 moves the funnel-shaped sealing ring 8, fixedly connected to its lower end, along the sampling cylinder. As the outer wall of the sampling cylinder 2 moves downward, the small opening of the funnel-shaped sealing ring 8 fits tightly against the side wall of the sampling cylinder 2, thus scraping away the oil adhering to the side wall of the sampling cylinder 2. At the same time, thanks to the installation block 12, the limiting cylinder 13, the telescopic rod 14, and the tension spring 15, the tension spring 15 drives the limiting cylinder 13, the installation block 12, and the funnel-shaped ring 11 to move upward. At this time, thanks to the fact that the funnel-shaped ring 11 and the funnel-shaped sealing ring 8 are of the same shape, the funnel-shaped ring 11 squeezes the funnel-shaped sealing ring 8, thereby making the funnel-shaped sealing ring 8 fit tightly against the outer wall of the sampling cylinder 2, thus increasing the cleaning effect.
