Description

Technical Field

[0001] The utility model relates to the technical field of laboratory bench fillers, in particular to a laboratory bench filler for oil-soluble demulsifier detection. Background Art

[0002] Demulsifier is a surfactant that can destroy emulsions. It mainly destroys emulsions by partially replacing the stabilizing film. It is used as a dehydrating agent to remove water from crude oil and heavy oil to meet the water content requirements. It can be used in oil wells to reduce the viscosity of crude oil and prevent oil wells from being blocked. It is obtained by the polymerization of fatty alcohol, propylene oxide and ethylene oxide. During the production process of oil-soluble demulsifier and during the random inspection process, it is necessary to collect part of the solution into the laboratory and add it into the reagent reaction bottle through the injector on the test bench. However, the existing test bench injector for oil-soluble demulsifier detection directly injects through a filling port when in use. However, in the actual detection process, it is necessary to fill it multiple times, and the required filling amount needs to be adjusted before each filling. During the adjustment process, it will affect the observation of the experimental reaction state. For this reason, a test bench filling for oil-soluble demulsifier detection is designed, which is convenient for preparing multiple injection solutions at one time before detection, avoiding multiple adjustments during the detection process that affect the observation of the detection test reaction changes, and is convenient for timely filling, so as to further improve the detection efficiency.

[0012] (III) Beneficial effects

[0013] Compared with the prior art, the utility model provides a laboratory bench filler for oil-soluble demulsifier detection, which has the following beneficial effects:

[0014] The experimental platform filler for oil-soluble demulsifier detection is convenient for filling the oil-soluble demulsifier solution at multiple positions through multiple transparent filling pipes and a valve is installed at the bottom of each transparent filling pipe. It is convenient to control the flow rate of the oil-soluble demulsifier flowing out through the transparent filling pipe through multiple flow control mechanisms respectively matched with each transparent filling pipe. Due to the cooperation of the sealing circular plate and the liquid hole, it is convenient to lower the sealing circular plate to the corresponding height in the transparent filling pipe according to the filling amount of the oil-soluble demulsifier solution required each time. Before entering the transparent filling pipe, under the action of the oil-soluble demulsifier solution, the hinged sealing gasket is lifted up, and it is convenient for the oil-soluble demulsifier to enter the upper part of the sealing circular plate through the liquid hole. When the sealing circular plate is closed, the sealing circular plate is opened. When the circular plate reaches the corresponding height, it is slowly laid flat under the action of gravity of the hinged sealing gasket to seal the liquid hole, so that each time the valve under the transparent filling pipe is opened, only the oil-soluble demulsifier under the sealing circular plate is discharged. In this way, the height of the sealing circular plates in the transparent filling pipe can be conveniently adjusted according to the predetermined filling amount each time, so as to facilitate multiple and timely filling during the detection process. The experimental bench filler for oil-soluble demulsifier detection is convenient for preparing multiple filling solutions at one time before the detection, avoiding multiple adjustments during the detection process that affect the observation of the detection test reaction changes, and convenient and timely filling, further improving the detection efficiency.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example:

[0023] See also Figure 1-5 A laboratory bench filler for oil-soluble demulsifier detection includes a filling tank 1, the bottom of the filling tank 1 is fixedly connected with a plurality of vertically arranged transparent filling pipes 2, the bottoms of the plurality of transparent filling pipes 2 are fixedly installed with valves 3, the filling tank 1 is provided with a plurality of groups of flow control mechanisms which are respectively adapted to each transparent filling pipe 2 and can be lifted and moved, and the flow control mechanism includes a sealing circular plate 6 which can be sealed and slidably matched with the inner wall of the transparent filling pipe 2 and can be lifted and moved, a liquid passing hole 12 is provided on the sealing circular plate 6, and a hinged sealing gasket 7 hinged to the sealing circular plate 6 is provided above the liquid passing hole 12.

[0024] Specifically, the top of the filling tank 1 is fixedly connected to a top plate 4, the top of each sealing circular plate 6 is fixedly connected to a fixing rod 9 through a connecting frame 8, the top of the fixing rod 9 is fixedly connected to a screw 10 threadedly connected to the top plate 4, and the top of the screw 10 is fixedly connected to an adjusting cap 11. The screw 10 can be driven to rotate clockwise or counterclockwise through the adjusting cap 11. When the screw 10 is rotated clockwise or counterclockwise, the screw 10, the fixing rod 9, the connecting frame 8, the sealing circular plate 6, and the hinged sealing gasket 7 can be synchronously driven to rotate downward or upward as a whole. When it moves downward, it can enter the transparent filling pipe 2. Furthermore, the side top of the filling tank 1 is fixedly connected to an adding pipe 5, which is convenient for adding the oil-soluble demulsifier solution to be tested into the filling tank 1 through the adding pipe 5.

[0025] Specifically, the bottom of the filling tank 1 is arranged in an arc shape, and one of the transparent filling pipes 2 is located at the lowest point of the filling tank 1, and the other multiple transparent filling pipes 2 are circumferentially arranged around the transparent filling pipe 2. The bottom of the filling tank 1 is arranged in an arc shape, and one of the transparent filling pipes 2 is located at the lowest point of the filling tank 1, so that the oil-soluble demulsifier can be completely discharged, avoiding the situation where there is oil-soluble demulsifier solution remaining in the filling tank 1.

[0026] Specifically, an embedded groove is provided at the top of the sealing circular plate 6, and the hinged sealing gasket 7 is hinged in the embedded groove. By providing the embedded groove, it is convenient to embed the hinged sealing gasket 7 into the embedded groove, thereby improving the tightness between the hinged sealing gasket 7 and the sealing circular plate 6 when the oil-soluble demulsifier at the bottom is discharged, and further ensuring the sealing performance at the liquid hole 12.

[0027] Specifically, it also includes a moving frame fixedly installed at the bottom of the filling tank 1. The moving frame facilitates the filling tank 1 to be supported and facilitates the horizontal movement of the filling tank 1 on the test bench.

[0029] When in use, pour the oil-soluble demulsifier to be tested into the filling tank 1, and according to the test results, lower each sealing circular plate 6 to the required height in each transparent filling tube 2. Before entering the transparent filling tube, under the action of the oil-soluble demulsifier solution, the hinged sealing gasket is lifted up, and it is convenient for the oil-soluble demulsifier to enter the top of the sealing circular plate through the liquid hole. When the sealing circular plate reaches the corresponding height, it is slowly laid flat under the action of the gravity of the hinged sealing gasket, and the liquid hole is sealed, so that a certain amount of oil-soluble demulsifier solution is stored under each sealing circular plate 6. Then the filling tank 1 is moved to the top of the reagent reaction bottle on the test bench. According to the situation, the valves 3 under the multiple transparent filling tubes 2 are opened in turn at a certain time interval, so that multiple streams of oil-soluble demulsifier solution are added to the reagent reaction bottle, and the reaction changes can be observed at the same time.
