Description

Technical Field

[0001] The utility model belongs to the technical field of biosurfactant preparation, in particular to a biosurfactant acid precipitation extraction device. Background Art

[0002] Biosurfactants are biodegradable surfactants. They possess the common properties of surfactants, such as solubilization, emulsification, wetting, foaming, dispersion, and surface tension reduction. Compared to other surfactants produced through chemical synthesis or petroleum refining, they also possess advantages such as non-toxicity, biodegradability, ecological safety, and high surface activity, offering broad application prospects in the petroleum sector. As biosurfactants, they exhibit low toxicity, good compatibility with the human body and the environment, and excellent emulsification, dispersing, and solubilization properties. They hold valuable research and development potential in fields such as oil drilling and production, and have been applied in the petroleum industry.

[0003] When biosurfactants are produced, they are often obtained by acid precipitation, in which the upper layer is the supernatant and the lower layer is the flocs. During extraction, the supernatant needs to be pumped out and the flocs are then discharged from the reaction tank.

[0004] Among them, the existing supernatant extraction method is to use a water pump to suck the supernatant into a suction pipe and extract it through the suction pipe. When the extraction is completed, the water pump is turned off, and the supernatant remaining in the suction pipe will return to the reaction tank under the action of gravity. Therefore, when the reaction tank discharges the flocs, some supernatant will remain, resulting in the collected flocs containing supernatant. Utility Model Content

[0005] The utility model provides a biosurfactant acid precipitation extraction device, which is used to solve the defects in the prior art.

[0006] The utility model is achieved through the following technical solutions:

[0007] A biosurfactant acid precipitation extraction device comprises a vertical pipe vertically arranged in a reaction tank, the upper part of the vertical pipe is connected to one end of a water suction pipe, and the other end of the water suction pipe is connected to a water suction device; the lower end of the vertical pipe is closed and has a water inlet, an inner pipe is provided in the vertical pipe, the inner pipe is sleeved with a rubber ring adapted to the vertical pipe, the inner pipe is adapted from top to bottom with a rotating plate and a fixed plate, the fixed plate is fixedly connected to the inner pipe, the rotating plate is rotatably connected to the fixed plate, the rotating plate and the fixed plate are respectively provided with a water inlet and a through hole that can communicate with each other, a pull rod is vertically arranged upward on the top surface of the rotating plate, the upper end of the pull rod is sleeved with a rubber plug adapted to the vertical pipe, and the water suction pipe is located below the rubber plug.

[0008] When the present application is in use, the water suction device is started, and the supernatant enters the vertical pipe through the through hole and the water inlet, and then enters the water suction device through the vertical pipe and the water suction pipe, so that the supernatant in the reaction tank is sucked out. When the suction is completed, the pull rod is rotated and the water suction device is closed. The rotation of the pull rod drives the rotation of the rotating plate, so that the water inlet and the through hole are misaligned, so that the liquid remains in the vertical pipe, and then the rotating plate is pulled upward, and the rotating plate drives the fixed plate to move upward, and the fixed plate drives the inner tube, and the inner tube drives the rubber ring to move upward, so that the supernatant remaining in the vertical pipe is lifted upward, and the supernatant flows into the water suction pipe when passing through the water suction pipe, so that the water in the vertical pipe is lifted out to prevent it from flowing back into the reaction tank, thereby avoiding the collected flocs containing supernatant.

[0009] Preferably, the water absorption device comprises a transparent measuring cup fixedly mounted on one side of the reaction tank. The top surface of the measuring cup is sealed and connected to one end of an air outlet pipe, the other end of which is connected to an air pump. The lower portion of the measuring cup is connected to the other end of the water absorption pipe, and the lower portion of the measuring cup is also provided with a water outlet pipe controlled by a valve. When the air pump is operating, it extracts gas from the measuring cup, thereby creating a negative pressure inside the measuring cup, thereby ensuring that liquid enters the measuring cup. When the air pump is not operating, the pressure inside and outside the measuring cup is the same.

[0010] Preferably, a groove is formed at the center of the top surface of the fixed plate, and a rotating rod is vertically connected downwardly from the center of the bottom surface of the rotating plate. The outer ring of the bearing is fixedly connected in the groove, and the rotating rod penetrates and is fixedly connected to the inner ring of the bearing. Rotation of the rotating plate drives rotation of the rotating rod, thereby realizing rotation of the rotating plate on the fixed plate.

[0011] Preferably, a horizontal plate is fixedly connected to the transparent tank, the horizontal plate having a through hole, a screw being rotatably connected to the through hole via a bearing, a round rod being vertically connected to the horizontal plate, a support plate being fixedly provided on one side of the vertical tube, the support plate having a threaded hole for the screw to pass through, a round hole for the round rod to pass through, a hose connected to one end of the suction pipe, and a measuring cup connected to the other end of the hose. When the screw is rotated, the threaded hole on the support plate engages with the screw thread, and the round rod passes through the round hole. Therefore, the rotation of the screw drives the support plate to move up and down, and in turn drives the vertical tube to move up and down, thereby adjusting the position of the vertical tube to achieve better suction of the supernatant.

[0012] Preferably, an annular groove is formed on the inner wall of the inner tube along its circumference, and an annular plate is fixedly sleeved on the outer wall of the rotating plate along its circumference, and the annular plate fits in the annular groove and slides in the annular groove.

[0013] Preferably, the top surface of the rubber stopper is vertically connected to a pull rod, and a handle is fixedly provided on the upper part of the pull rod.

[0014] The beneficial effect of the present invention is that the use of the present application can make it possible to push the supernatant in the vertical tube into the measuring cup by utilizing the upward movement of the piston ring after the supernatant is sucked out by the air pump, thereby preventing the supernatant in the vertical tube from flowing back into the reaction tank under the action of gravity, thereby avoiding the supernatant being contained in the collected flocs.

The lower part of the measuring cup is connected to the other end of the water absorption pipe. The lower part of the measuring cup is also provided with a water outlet pipe controlled by a valve.

[0023] The lower end of the vertical pipe is closed and provided with a water inlet, and the vertical pipe is provided with an inner pipe, the inner pipe is sleeved with a rubber ring matched with the vertical pipe, the inner pipe is matched with a rotating plate and a fixed plate from top to bottom, the fixed plate is fixedly connected with the inner pipe, the rotating plate is rotatably connected with the fixed plate, the rotating plate and the fixed plate are respectively provided with a water inlet and a through hole which are communicated, the top surface of the rotating plate is vertically provided with a pull rod, the upper end of the pull rod is sleeved with a rubber plug matched in the vertical pipe, and the water suction pipe is located below the rubber plug.

[0024] When the present application is used, the rubber plug can play a role in closing the vertical pipe, and the water suction device is started. When the air pump works, the gas in the measuring cup is extracted, so that negative pressure can be generated in the measuring cup, thereby ensuring that the liquid enters the measuring cup. When the air pump does not work, the pressure inside and outside the measuring cup is the same. When the air pump works, under the action of negative pressure, the supernatant enters the vertical pipe through the through hole and the water inlet, and then enters the water suction device through the vertical pipe and the water suction pipe, so that the supernatant in the reaction tank is sucked out. When the suction is completed, the rotating pull rod is rotated and the water suction device is closed. The rotation of the pull rod drives the rotation of the rotating plate, so that the water inlet and the through hole are misaligned, thereby causing the liquid to remain in the vertical pipe. Then pull the rotating plate upwards, the rotating plate drives the fixed plate to move upwards, the fixed plate drives the inner pipe, the inner pipe drives the rubber ring to move upwards, thereby lifting the supernatant remaining in the vertical pipe upwards. When the supernatant flows into the water suction pipe, the water in the vertical pipe is extracted, preventing it from flowing back to the reaction tank, thereby avoiding the collected flocculated material containing supernatant.

[0025] A groove is formed in the center of the top surface of the fixed plate, a rotating rod is vertically connected to the center of the bottom surface of the rotating plate, and the outer ring of the bearing is fixedly connected in the groove. The rotating rod penetrates the inner ring of the bearing and is fixedly connected with the inner ring of the bearing.

[0026] The transparent tank is fixedly connected with a horizontal plate, the horizontal plate is provided with a through hole, a screw rod is rotatably connected in the through hole through a bearing, and a circular rod is vertically connected to the horizontal plate.

One end of the water suction pipe is connected with a hose, and the other end of the hose is connected with a measuring cup. The rotating screw rod is screwed with the silk hole on the support plate and penetrates the circular hole, so that the rotation of the screw rod drives the support plate to move up and down, thereby driving the vertical pipe to move up and down, adjusting the position of the vertical pipe, and realizing better suction of the supernatant.

[0027] An annular groove is formed in the inner wall of the inner pipe along the circumference thereof, and an annular plate is fixedly sleeved on the outer wall of the rotating plate along the circumference thereof.
