Description

Technical Field

[0001] This utility model belongs to the field of petroleum testing technology, specifically a dilution device for petroleum testing. Background Technology

[0002] Petroleum is a naturally formed viscous liquid hydrocarbon mixture, mainly composed of alkanes, cycloalkanes, and aromatics, and contains small amounts of impurities such as sulfur, nitrogen, and oxygen. Petroleum testing refers to the process of determining the quality, composition, and properties of crude oil, refined oil products, and petroleum products through chemical, physical, and instrumental analytical methods.

[0003] In petroleum testing, dilution is required to reduce the viscosity or concentration of the sample, making it easier to analyze. However, traditionally, when diluting petroleum, the diluent is usually added to the container along with the petroleum. This one-time and rapid addition of the solvent may lead to excessively high local concentrations, forming micelles or precipitates, thus affecting the dilution effect. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides a dilution device for petroleum testing, which solves the problem that the one-time and rapid addition of solvent may lead to excessively high local concentrations, forming colloids or precipitates, thereby affecting the dilution effect.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a dilution device for petroleum testing, comprising a chamber, an mounting plate connected to the top of the chamber, a transparent chamber door rotatably mounted on one side of the chamber, a magnetic plate connected to the other side of the chamber, a dilution cylinder disposed inside the chamber, a fixing plate connected inside the chamber, insertion holes provided on the walls on both sides of the chamber, a solvent chamber disposed on one side of the mounting plate, and a motor fixedly mounted above the mounting plate;

[0006] A liquid pump is fixedly installed below the mounting plate. A hydraulic push rod is fixedly installed on the mounting plate. A connecting plate is connected to the movable end of the hydraulic push rod. A rotating rod is rotatably connected to the connecting plate. A stirring plate is connected to one end of the rotating rod. A connecting shaft is connected to the motor output shaft. A connecting pipe is connected to one side of the liquid pump. A liquid outlet pipe is connected to the liquid pump.

[0007] As a further embodiment of this utility model: a screw is threadedly connected to the fixing plate, a handwheel is connected to one end of the screw, a clamping plate is rotatably connected to the other end of the screw, and guide rods are connected to both sides of the clamping plate, the guide rods sliding in the insertion hole.

[0008] As a further embodiment of this utility model: limit grooves are provided on the inner walls of both sides of the rotating rod, the connecting shaft is rotatably connected to the mounting plate through a bearing and inserted into the rotating rod, and one end of the connecting shaft is connected to a limit block, the limit block sliding in the limit groove.

[0009] As a further embodiment of this utility model: a viewing window is installed on one side of the solvent chamber, and a liquid injection tube is connected to the upper side of the solvent chamber; the viewing window is provided with a scale.

[0010] As a further embodiment of this utility model: the connecting pipe is connected to the solvent chamber, the liquid outlet pipe is located above the opening of the dilution cylinder, and the clamping plate and the inner wall of the chamber are both arc-shaped.

[0011] As a further embodiment of this utility model: a second magnetic plate is connected to one side of the transparent compartment door, the first magnetic plate and the second magnetic plate attract each other, and an anti-slip mat is connected to the bottom of the compartment body.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This petroleum testing dilution device comprises a liquid pump, connecting pipe, outlet pipe, motor, connecting shaft, hydraulic push rod, rotating rod, and stirring plate. During dilution, the hydraulic push rod pushes the connecting plate downward, causing the stirring plate to extend into the dilution cylinder. Then, the motor is started to rotate the connecting shaft, which, through a limit block, drives the rotating rod to rotate the stirring plate. During this process, the liquid pump draws solvent from the solvent chamber through the connecting pipe, and then slowly adds it into the dilution cylinder through the outlet pipe. This achieves a controllable and uniform petroleum dilution process, and the stirring plate can break up clumps or sediments, thereby improving dilution efficiency.

[0014] 2. This petroleum testing dilution device is equipped with a handwheel, screw, clamping plate, and magnetic plate one and magnetic plate two. Turning the handwheel to turn the screw causes the screw to move the clamping plate, which then presses and fixes the dilution cylinder to prevent it from sliding and tipping over during stirring, thus reducing uneven mixing or sample spillage caused by shaking. The magnetic attraction of magnetic plate one and magnetic plate two allows the operator to quickly open or close the transparent compartment door, making operation simple.

Detailed Implementation

[0020] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0021] like Figure 1-4 As shown, this utility model provides a technical solution: a dilution device for petroleum testing, including a chamber 1, an mounting plate 2 connected to the top of the chamber 1, a transparent door 3 rotatably mounted on one side of the chamber 1, a magnetic plate 26 connected to one side of the transparent door 3, a magnetic plate 4 and a magnetic plate 26 adsorbing each other, and an anti-slip pad 27 connected to the bottom of the chamber 1. Through the adsorption of the magnetic plate 4 and the magnetic plate 26, the transparent door 3 can be quickly closed and opened, improving convenience.

[0022] A magnetic plate 4 is connected to the other side of the chamber 1. A dilution cylinder 5 is installed inside the chamber 1. A fixing plate 6 is connected inside the chamber 1. A screw 18 is threaded onto the fixing plate 6. A handwheel 19 is connected to one end of the screw 18. A clamping plate 20 is rotatably connected to the other end of the screw 18. Guide rods 21 are connected to both sides of the clamping plate 20. The guide rods 21 slide in the insertion hole 7. When the screw 18 pushes the clamping plate 20 to move, the guide rods 21 will pass through the insertion hole 7, thereby limiting the clamping plate 20 through the guide rods 21, preventing the clamping plate 20 from rotating, and making the clamping plate 20 move smoothly.

[0023] Insertion holes 7 are provided on the walls on both sides of the container 1. A solvent chamber 8 is provided on one side of the mounting plate 2. A viewing window 24 is installed on one side of the solvent chamber 8. A liquid injection pipe 25 is connected to the upper side of the solvent chamber 8. The viewing window 24 is provided with a scale. The staff can easily observe the amount of solvent in the solvent chamber 8 through the viewing window 24, and the scale on the viewing window 24 can help the staff determine the amount of solvent discharged.

[0024] A motor 9 is fixedly installed above the mounting plate 2, and a hydraulic pump 10 is fixedly installed below the mounting plate 2. A hydraulic push rod 11 is fixedly installed on the mounting plate 2. A connecting plate 12 is connected to the movable end of the hydraulic push rod 11. A rotating rod 13 is rotatably connected to the connecting plate 12. Limiting grooves 22 are opened on the inner walls of both sides of the rotating rod 13. A connecting shaft 15 is rotatably connected to the mounting plate 2 through a bearing and is inserted into the rotating rod 13. One end of the connecting shaft 15 is connected to a limiting block 23. The limiting block 23 slides in the limiting groove 22. The limiting block 23 enables the connecting shaft 15 to drive the rotating rod 13 to rotate. The sliding of the limiting block 23 in the limiting groove 22 enables the rotating rod 13 to slide smoothly on the connecting shaft 15 and prevents slippage.

[0025] One end of the rotating rod 13 is connected to the stirring plate 14, the output shaft of the motor 9 is connected to the connecting shaft 15, one side of the liquid pump 10 is connected to the connecting pipe 16, the liquid pump 10 is connected to the outlet pipe 17, the connecting pipe 16 is connected to the solvent chamber 8, the outlet pipe 17 is located above the opening of the dilution cylinder 5, the clamping plate 20 and the inner wall of the chamber 1 are both arc-shaped, the arc-shaped design of the clamping plate 20 and the inner wall of the chamber 1 can increase the contact area with the dilution cylinder 5, thereby enhancing the stability of the fixation.

[0026] The working principle of this utility model is as follows:

[0027] The dilution cylinder 5 containing the sample is placed inside the chamber 1. Then, the screw 18 is turned by the handwheel 19, causing the screw 18 to push the clamping plate 20 to move, so that the clamping plate 20 can press and fix the dilution cylinder 5, thereby preventing the dilution cylinder 5 from sliding and tipping over during stirring. Then, the transparent chamber door 3 is closed, so that the magnetic plate 4 and the magnetic plate 26 attract each other. Then, the hydraulic push rod 11 is started to push the connecting plate 12 down, so that the rotating rod 13 slides on the connecting shaft 15, causing the stirring plate 14 to extend into the dilution cylinder 5. Then, the motor 9 is started to rotate the connecting shaft 15, so that the connecting shaft 15 drives the rotating rod 13 through the limit block 23 to rotate the stirring plate 14. During the process, the liquid pump 10 draws the solvent out of the solvent chamber 8 through the connecting pipe 16, and then slowly adds it into the dilution cylinder 5 through the liquid outlet pipe 17, thereby realizing a controllable and uniform petroleum dilution process. The rotating stirring plate 14 can break up clumps or sediments.
