Description

Technical Field

[0001] This utility model relates to the field of demulsifier detection technology, and in particular to a demulsifier detection device. Background Technology

[0002] Demulsifiers are surfactants that can break down emulsions. They mainly break down emulsions by partially replacing the stabilizing film. As dehydrating agents, they can remove water from crude oil and heavy oil to achieve the required water content.

[0003] For example, Chinese utility model patent CN202422395957.2 discloses a quality testing device for demulsifier production, including a collar with a reaction vessel movably connected to its inner side. A first motor is turned on, driving a screw to rotate, lowering a slider and a lifting arm on one side of the slider, along with a scale, until the stirring blade is submerged in the solution within the collar. Then, a second motor is turned on, rotating a shaft to stir the solution. The state of the solution is observed to determine the effectiveness of the demulsifier. Finally, the operation is reversed, raising the lifting arm until the stirring blade is detached from the inside of the reaction vessel, removing the reaction vessel, and processing the tested solution. This effectively avoids the need for manual stirring of the mixed solution, reducing physical exertion. After testing, an external cable is connected to a terminal block to heat the heating element, aiding in drying any remaining solution in the reaction vessel, accelerating drying efficiency, and reducing the risk of bacterial growth.

[0004] After use, the reaction vessels of the above-mentioned equipment need to be removed for manual cleaning and then electrically dried before the demulsifier can be tested. The operation process is cumbersome and reduces the efficiency of demulsifier quality testing. Utility Model Content

[0005] This utility model discloses a demulsifier testing device, which solves the problem that the cleaning process of reaction vessels after use is cumbersome and reduces the efficiency of demulsifier quality testing.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A demulsifier testing device includes a support frame, a collection box and a first motor fixed on the support frame, a bidirectional lead screw fixed on the shaft of the first motor, a fixing ring above the collection box, a reaction vessel with an open top and bottom rotatably connected to the inner side of the fixing ring, a partition dividing the interior of the reaction vessel into upper and lower storage spaces fixed inside the reaction vessel, a second motor inside the support frame for driving the fixing ring to rotate so that the top and bottom of the reaction vessel are interchanged, and a third motor on the fixing ring for driving the reaction vessel to rotate; an upper plate and a lower plate are respectively threadedly connected to the bidirectional lead screw above and below the reaction vessel, a stirring assembly is provided on the upper plate, and a spray pipe and an exhaust pipe for discharging hot air are fixed on the lower plate.

[0008] Compared with the prior art, the present invention has the following beneficial effects:

[0009] After the waste liquid is placed into the reaction vessel, it sits on the partition plate. Then, the demulsifier sample is added. The first motor is then activated, driving the bidirectional screw to rotate, bringing the upper and lower plates closer together. This allows the stirring assembly to enter the reaction vessel from the top, while the spray pipe and exhaust pipe enter from the bottom. Next, the third motor is activated, driving the reaction vessel to rotate. The stirring assembly begins to agitate the waste liquid. After agitation, the state of the waste liquid is observed to assess the effectiveness of the demulsifier. Subsequently, the upper and lower plates are moved apart, and the second motor is activated, causing the fixing ring to rotate the reaction vessel. When the reaction vessel is horizontal, the waste liquid is discharged into a collection tank. After the waste liquid is discharged... The reaction vessel is then rotated to swap the positions of its top and bottom. Workers can then continue adding waste liquid from the top of the vessel and repeat the above steps to test the demulsifier sample. A spray pipe sprays water to rinse the inner wall of the storage space after use, and a subsequent exhaust pipe expels hot air to dry the vessel. This invention allows for rapid testing of demulsifier samples and automatic cleaning of the storage space after use by simply swapping the top and bottom of the reaction vessel. It eliminates the need for manual cleaning of the inside of the vessel after removal, reducing the workload of workers and improving the efficiency of demulsifier quality testing.

Detailed Implementation

[0015] The specific content of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0016] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, this utility model provides a demulsifier detection device, including a support frame 1, a collection box 2 and a first motor 3 fixed on the support frame 1, a bidirectional lead screw 31 fixed on the shaft of the first motor 3, a fixing ring 4 above the collection box 2, a reaction dish 5 with an open top and bottom rotatably connected to the inner side of the fixing ring 4, a partition 51 that divides the interior of the reaction dish 5 into upper and lower storage spaces fixed inside the reaction dish 5, a second motor 41 for driving the fixing ring 4 to rotate so that the top and bottom of the reaction dish 5 are interchanged inside the support frame 1, and a third motor 43 for driving the reaction dish 5 to rotate on the fixing ring 4; an upper plate 6 and a lower plate 7, which are threadedly connected to the bidirectional lead screw 31, are respectively provided above and below the reaction dish 5, the upper plate 6 is provided with a stirring assembly, and the lower plate 7 is fixed with a spray pipe 8 and an exhaust pipe 9 for discharging hot air. The first motor 3, the second motor 41, and the third motor 43 are all servo motors. A battery (not shown in the figure) for supplying power to the third motor 43 is fixed on the fixing ring 4. The third motor 43 can also be powered by wires. After the waste liquid is put into the reaction vessel 5, the waste liquid is located on the partition 51 inside the reaction vessel 5. Then, the demulsifier sample is put into the reaction vessel 5. Then, the first motor 3 is started to drive the bidirectional lead screw 31 to rotate, so that the upper plate 6 and the lower plate 7 move closer to each other, so that the stirring component enters the reaction vessel 5 from the top. The spray pipe 8 and the exhaust pipe 9 enter the reaction vessel 5 from the bottom. Then, the third motor 43 is started to drive the reaction vessel 5 to rotate, and the stirring component begins to stir the waste liquid in the reaction vessel 5. After stirring is completed, the mixture is observed. The state of the waste liquid is used to determine the effectiveness of the demulsifier. Subsequently, the upper plate 6 and lower plate 7 are moved apart, and the stirring assembly and spray pipe 8 are removed from the reaction vessel 5. The second motor 41 is started, causing the fixing ring 4 to rotate the reaction vessel 5 clockwise by 90°. When the reaction vessel 5 is horizontal, the waste liquid is discharged from the reaction vessel 5 into the collection box 2. After the waste liquid is discharged, the reaction vessel 5 is rotated clockwise by 90° again, swapping the positions of the top and bottom. Then, the operator can continue to add waste liquid from the top of the reaction vessel 5 and repeat the above operation to test the demulsifier sample. The spray pipe 8 sprays water to rinse the inner wall of the storage space after use of the reaction vessel 5. Subsequently, the exhaust pipe 9 discharges hot air to dry the reaction vessel 5.

[0017] like Figure 1 and Figure 4As shown, the stirring assembly includes a vertical tube 61 rotatably connected to the upper plate 6, with blades 611 fixed on the vertical tube 61. A fourth motor 62 is fixed on the upper plate 6, and a driving gear and a driven gear are respectively fixed to the shaft of the fourth motor 62 and the vertical tube 61. A connecting pipe 612 with a perforation at the bottom is connected to the vertical tube 61. A storage frame 63 is fixed on the upper plate 6, and the discharge end of the storage frame 63 is inserted into the top of the vertical tube 61. When the fourth motor 62 is started, the driving gear drives the vertical tube 61 to rotate through the driven gear, causing the blades 611 to start stirring the waste liquid in the reaction vessel 5. At the same time, a demulsifier sample can be put into the storage frame 63, and the demulsifier sample enters the vertical tube 61 through the discharge end of the storage frame 63, and then is discharged through the perforation at the bottom of the connecting pipe 612. This allows the demulsifier sample to be evenly distributed in the reaction vessel 5 when the connecting pipe 612 rotates, so that the demulsifier sample can be better mixed with the waste liquid.

[0018] like Figure 1 and Figure 3 As shown, one side of the reaction vessel 5 is provided with a fixed cylinder 52 connected to the fixed ring 4. A ring-shaped fixed tube 521 is fixed inside the fixed cylinder 52. A set of cleaning tubes 522 are connected to the fixed tube 521. A through hole is opened on the side of the cleaning tube 522 near the axis of the fixed cylinder 52. A flexible tube 523 is connected to the fixed tube 521. A fixed block 32 connected to the second motor 41 is fixed on the inner side of the support frame 1. A rotating rod 411 is fixed on the rotating shaft of the second motor 41. A circular plate 42 connected to the rotating rod 411 is fixed on the fixed ring 4. A sliding rod 421 slidably connected to the fixed block 32 is fixed on the circular plate 42. After the reaction vessel 5 is used, the second motor 41 drives the circular plate 42 to rotate the fixed ring 4 by 90° via the rotating rod 411, so that the reaction vessel 5 is in a horizontal position, so that the waste liquid in the reaction vessel 5 can be discharged into the collection tank 2. At this time, the open part at the top of the fixed cylinder 52 corresponds to the blade 611. The first motor 3 is started to drive the bidirectional lead screw 31 to rotate, so that the blade 611 moves downward with the upper plate 6 and enters the fixed cylinder 52, so that the blade 611 is located between a set of cleaning pipes 522. The hose 523 is connected to the external water pump, and water enters the fixed pipe 521. After being discharged through the perforations on the cleaning pipe 522, the blades 611 and the vertical pipe 61 can be cleaned. At the same time, the fourth motor 62 is started to rotate the vertical pipe 61 to facilitate the all-round cleaning of the blades 611. After cleaning, the vertical pipe 61 can also be rotated to shake off the water on the blades 611. The fixing block 32 has a hole for the bidirectional lead screw 31 to pass through, and the fixing block 32 has a ring-shaped groove that matches the slide rod 421. The slide rod 421 can increase the stability of the circular plate 42 after rotating with the circular plate 42.

[0019] like Figure 1As shown, the upper plate 6 and lower plate 7 are slidably connected to the inner wall of the support frame 1, and the collection box 2 is located below the lower plate 7; the spray pipe 8 and the exhaust pipe 9 are respectively arranged in an L-shape, and spray holes and exhaust holes are respectively opened on the outer walls of the spray pipe 8 and the exhaust pipe 9. The first rubber tube 81 and the second rubber tube 91 are respectively connected to the spray pipe 8 and the exhaust pipe 9. Brush bristles 82 are fixed on the outer wall of the spray pipe 8. The shaft of the third motor 43 and the reaction vessel 5 are respectively fixed with meshing small gears and large gears. The first rubber tube 81 and the second rubber tube 92 are respectively connected to an external water pump and a warm air blower. When the spray pipe 8 discharges water, the third motor 43 drives the reaction vessel 5 to rotate, so that the water sprayed by the spray pipe 8 can thoroughly rinse the storage space located below the partition 51 inside the reaction vessel 5. With the help of the brush 82, the inner wall of the reaction vessel 5 can be further cleaned. After rinsing the inner wall of the reaction vessel 5, the warm air can be discharged through the exhaust hole on the exhaust pipe 9 to quickly dry the inner wall of the reaction vessel 5. The third motor 43 drives the reaction vessel 5 to rotate counterclockwise, while the fourth motor 62 drives the vertical pipe 61 to rotate clockwise, so as to better stir the waste liquid and demulsifier sample inside the reaction vessel 5.
