[0023] Example

[0024] See also Figure 1-Figure 4 The utility model provides a demulsifier filling device, including a filling mechanism 10 and a suspension mechanism 20.

[0025] The filling mechanism 10 is used for filling demulsifier, and the suspension mechanism 20 cooperates with the filling mechanism 10 to reduce the oil spraying onto the oil well wall, improve the accuracy of filling demulsifier and reduce the waste of demulsifier.

[0026] See also Figure 1 , Figure 2 and Figure 4 The filling mechanism 10 includes a medicine storage tank 110, a water pump 120, a sedimentation pipe 140 and a nozzle 150. The liquid inlet port of the water pump 120 is connected to the medicine storage tank 110 through a connecting pipe 130. The liquid outlet port of the water pump 120 is connected to one end of the sedimentation pipe 140, and a branch pipe 160 is connected to the outside of the other end of the sedimentation pipe 140, and the nozzle 150 is installed at the end of the branch pipe 160. The suspension mechanism 20 includes an electric hoist 210 and a support 220. The support 220 is fixedly sleeved on the outside of the lower section of the sedimentation pipe 140 by bolts, and the bottom end of the rope of the electric hoist 210 is fixed to the support 220.

[0027] The electric hoist 210 drives the rope to adjust the support 220 in the oil well, that is, drives the nozzle 150 at the bottom of the settling pipe 140 to move close to the oil surface. The water pump 120 extracts the demulsifier in the medicine storage tank 110 through the connecting pipe 130, and then sprays it from the nozzle 150 into the oil through the settling pipe 140 and the branch pipe 160. The demulsifier filling device can effectively reduce the injection of the added demulsifier into the well wall, which not only saves the use of demulsifier, but also ensures the precision of the ratio of the injected demulsifier to the oil.

[0028] For further information, see Figure 2 The filling mechanism 10 further includes an electric valve 161, which is disposed on the branch pipe 160. The nozzle 150 can be disposed in multiple groups, and the electric valve 161 is used to control the start and stop of the nozzle 150.

[0029] In the above specific implementation, please refer to Figure 1 and Figure 2 The settling pipe 140 includes a standpipe 141 and a hose 142. One end of the hose 142 is connected to the liquid outlet port of the water pump 120, and the other end of the hose 142 is connected to the top of the standpipe 141. One end of the branch pipe 160 is connected to the outer wall of the standpipe 141, and the support 220 is fixedly sleeved on the outside of the standpipe 141 by bolts. The filling mechanism 10 also includes a floating seat 170, which is fixedly arranged at the bottom end of the standpipe 141. The setting of the floating seat 170 can make the standpipe 141 float above the oil to prevent the standpipe 141 from sinking too deep into the oil well.

[0030] Specifically, see Figure 1 and Figure 4 The filling mechanism 10 also includes a liquid level meter 190, which is installed on the outside of the medicine storage tank 110. The liquid level meter 190 is set to monitor the liquid level of the medicine solution inside the medicine storage tank 110 in real time. The filling mechanism 10 also includes a stirring assembly 180, which is arranged inside the medicine storage tank 110. The stirring assembly 180 includes a motor 181, a stirring part 182 and a stirring rod 183. The motor 181 is installed on the top of the medicine storage tank 110, and the stirring rod 183 is located inside the medicine storage tank 110. The top end of the stirring rod 183 rotates and passes through the top wall of the medicine storage tank 110 and is connected to the output shaft end of the motor 181. The stirring part 182 is arranged at the bottom end of the stirring rod 183. The stirring part 182 includes a sleeve 1821 and a stirring blade 1822. The sleeve 1821 is fixedly sleeved on the outside of the bottom end of the stirring rod 183, and the stirring blade 1822 is installed on the outside of the sleeve 1821. The motor 181 in the stirring assembly 180 drives the stirring rod 183 to rotate, and the rotating stirring rod 183 drives the stirring part 182 to rotate to mix the liquid medicine inside the medicine storage tank 110 .

[0031] It should be noted that the specific model specifications of the water pump 120, the electric valve 161, the motor 181, and the electric hoist 210 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be described in detail. The power supply and principle of the water pump 120, the electric valve 161, the motor 181, and the electric hoist 210 are clear to those skilled in the art and will not be described in detail here.

[0032] The working principle of the demulsifier filling device: when in use, the electric hoist 210 drives the rope to adjust the support 220 up and down inside the oil well, that is, drives the nozzle 150 at the bottom of the sedimentation pipe 140 to move close to the oil surface. The water pump 120 extracts the demulsifier inside the medicine storage tank 110 through the connecting pipe 130, and then sprays it from the nozzle 150 into the oil through the sedimentation pipe 140 and the branch pipe 160. The demulsifier filling device can effectively reduce the injection of the injected demulsifier into the well wall, which not only saves the use of demulsifier, but also ensures the precision of the ratio of the injected demulsifier to the oil.

[0033] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
