Description

Technical Field

[0001] This utility model relates to the technical field of oil-water separation devices, and in particular to an oil-water separation device for rosin production. Background Technology

[0002] Rosin is a resin from a pine tree belonging to the Pinaceae family. Its main component is C19H29COOH. In the production process, rosin is generally processed by distillation. The distillation process includes an oil-water separation process. The oil-water separation process in rosin production basically takes advantage of the difference in density between oil and water, which causes the oil and water to separate into layers. After the oil-water mixture is left to stand for a certain period of time, the oil and water are separated using methods such as gravity separation.

[0003] For example, Chinese utility model patent application number 202221696734.4 discloses an oil-water separation device for rosin production, including a tank body. Inside the tank body is a shell that can be raised and lowered and has holes on its surface. The bottom of the shell is connected to a retractable discharge pipe that sequentially discharges oil and water from the tank body to the outside. The discharge pipe includes a folded pipe connected to the bottom of the shell, the bottom end of which is fixed to the bottom of the tank body. The bottom end of the folded pipe is connected to a discharge pipe that penetrates the bottom of the tank body and is fixed thereto. Below the tank body is a collection shell that can be moved to below the discharge pipe. A superhydrophobic separation membrane is fixed inside the collection shell, and the collection shell also has a through hole for discharging the water separated by the superhydrophobic separation membrane. This utility model can maximize the separation of oil and water, improve the efficiency of oil and water separation, minimize oil waste, and facilitate the treatment of the separated water by workers.

[0004] Although the above-mentioned equipment can effectively separate oil and water, the oil is located on top of the water, and the folded tube still has a certain length after compression, which prevents the shell from contacting the bottom of the tank. Therefore, the equipment can only discharge the oil first and then the water, and cannot discharge the oil and water separately at the same time. This results in a slow overall emptying efficiency of the oil and water in the tank, which affects the storage and separation efficiency of the tank for the next batch of oil-water mixture. Summary of the Invention

[0005] This utility model discloses an oil-water separation device for rosin production, which solves the problem that the oil and water cannot be discharged separately at the same time, resulting in a slow overall emptying efficiency of the oil and water in the tank.

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

[0007] An oil-water separation device for rosin production includes a tank, a liftable shell inside the tank, an oil inlet pipe connected to the shell, a lifting assembly for driving the shell on the tank, a retractable discharge pipe for discharging oil connected to the bottom of the shell, a discharge pipe connected to the bottom of the tank, a liftable cylinder below the tank, a superhydrophobic separation membrane fixed inside the cylinder, a perforation for the discharge pipe to pass through the superhydrophobic separation membrane, a sealing plug for sealing the perforation on the superhydrophobic separation membrane below the discharge pipe, a connecting rod connected to the discharge pipe fixed to the sealing plug; a through hole for discharging water separated by the superhydrophobic separation membrane on the cylinder, and an automatic telescopic rod for driving the cylinder on the tank.

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

[0009] The oil-water mixture is stored in the tank and left to stand for a period of time, allowing the oil and water to separate. Then, the lifting assembly is activated to move the shell downwards, allowing the oil to enter the shell through the inlet pipe and then be discharged through the discharge pipe. Simultaneously, the discharge pipe can be opened to drain the water in the tank into the cylinder. The water falls onto the superhydrophobic separation membrane and then is discharged through the through-hole. After the water in the tank is completely drained, some oil is discharged through the discharge pipe along with the water. The oil passes through the superhydrophobic separation membrane and falls to the bottom of the cylinder, then is discharged through the discharge end at the bottom of the cylinder. Then, the automatic telescopic rod is activated to move the cylinder upwards, allowing the bottom of the discharge pipe to pass through the perforations on the superhydrophobic separation membrane, and the discharge pipe can directly discharge the oil into the cylinder. This invention can discharge oil and water simultaneously, improving the efficiency of overall tank emptying and allowing the next batch of oil-water mixture to be stored in the tank in a timely manner.

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 and Figure 2As shown, this utility model provides an oil-water separation device for rosin production, including a tank body 1, a liftable shell 2 inside the tank body 1, an oil inlet pipe connected to the shell 2, a lifting assembly for driving the shell 2 on the tank body 1, a retractable discharge pipe 3 for discharging oil connected to the bottom of the shell 2, a discharge pipe 12 connected to the bottom of the tank body 1, a liftable cylinder 4 below the tank body 1, a superhydrophobic separation membrane 41 fixed inside the cylinder 4, a perforation for the discharge pipe 12 to pass through the superhydrophobic separation membrane 41, a sealing plug 13 for sealing the perforation on the superhydrophobic separation membrane 41 below the discharge pipe 12, a connecting rod connected to the discharge pipe 12 fixed on the sealing plug 13; a through hole 42 for discharging water separated by the superhydrophobic separation membrane 41 on the cylinder 4, and an automatic telescopic rod 5 for driving the cylinder 4 on the tank body 1. After the oil-water mixture is stored in tank 1 through the feed pipe, it is allowed to stand for a period of time to allow the oil and water to separate. Then, the shell 2 is moved downwards, allowing the oil to enter the shell 2 through the oil inlet pipe and be discharged through the discharge pipe 3. At the same time, the solenoid valve on the discharge pipe 12 can be opened to drain the water in tank 1 into cylinder 4. The superhydrophobic separation membrane 41 is designed with a convex arc shape at the top. When the water comes into contact with the top surface of the superhydrophobic separation membrane 41, it flows downwards and is finally discharged through the through hole 42. When the water in tank 1 is about to be completely drained, some oil is discharged with the water. When the oil comes into contact with the superhydrophobic separation membrane 41, it passes through the superhydrophobic membrane. The separator 41 falls to the bottom of the cylinder 4 and is then discharged through the discharge end at the bottom of the cylinder 4. The fixed end of the automatic telescopic rod 5 is fixed to the bottom of the tank 1, and the telescopic end of the automatic telescopic rod 5 is connected to the top of the cylinder 4. When the automatic telescopic rod 5 is activated, the cylinder 4 moves upward, and the sealing plug 13 is positioned below the perforation of the superhydrophobic separator 41. The bottom end of the discharge pipe 12 passes through the perforation, and the oil in the tank 1 can be directly discharged to the bottom of the superhydrophobic separator 41, so that the oil is discharged through the discharge end at the bottom of the cylinder 4. This can be used in conjunction with the shell 2 to discharge the oil in the tank 1 at the same time, and can effectively prevent the oil near the bottom of the tank 1 from being discharged after the shell 2 descends to its limit.

[0017] like Figure 1As shown, the lifting assembly includes a connecting plate 7 fixed to the tank body 1. A motor 71 is fixed to the top of the connecting plate 7. A lead screw 72, which is rotatably connected to the top of the tank body 1, is fixed to the rotating shaft of the motor 71. A lifting plate 73 is threaded onto the lead screw 72. The lifting plate 73 is slidably connected to the connecting plate 7 and a vertical rod 74 is fixed to its bottom. The other end of the vertical rod 74 passes through the tank body 1 and is connected to the shell 2. A sealing ring 6 for sealing the oil inlet pipe is sleeved on the outside of the shell 2. A fixing rod 61, which passes through the tank body 1, is fixed to the top of the sealing ring 6. An electric telescopic rod 62 for driving the fixing rod 61 to rise and fall is fixed on the lifting plate 73. Motor 71 is a servo motor. Starting motor 71 causes screw 72 to rotate, which in turn causes lifting plate 73 to move housing 2 upwards or downwards via vertical rod 74. This allows oil to enter the oil inlet pipe on housing 2 and be discharged through discharge pipe 3. Furthermore, when sampling is required to test oil-water separation in tank 1, sealing ring 6 and housing 2 move downwards synchronously into the oil-water mixture. Activating electric telescopic rod 62 drives fixed rod 61 downwards, causing sealing ring 6 to move downwards and stop the oil inlet pipe on housing 2 from being discharged. If the feed pipe is blocked, the oil-water mixture in tank 1 can be sampled and discharged through discharge pipe 3. Then, the sealing ring 6 can be restored. Furthermore, the shell 2 and the sealing ring 6 can be moved to different heights to sample and test the oil-water mixture at different locations in tank 1, improving the accuracy of the test. When it is necessary to discharge the oil, the sealing ring 6 can be moved downwards to stop blocking the oil inlet pipe on the shell 2. The telescopic end of the electric telescopic rod 62 is connected to the top of the fixed rod 61, and the fixed rod 61 is slidably connected to the tank 1.

[0018] like Figure 1 and Figure 4 As shown, the tank 1 is provided with a movable ring 8 that contacts the inner wall of the tank 1. A horizontal bar 81 connected to the vertical rod 74 is fixed on the movable ring 8. When the vertical rod 74 drives the housing 2 to move downward, the movable ring 8 moves downward along with the horizontal bar 81, which can scrape off the oil adhering to the inner wall of the tank 1, thus preventing excessive oil from adhering to the inner wall of the tank 1.

[0019] like Figure 1 and Figure 3As shown, the discharge pipe 3 includes a folded pipe 31 connected to the bottom of the shell 2. The bottom of the folded pipe 31 is connected to a connecting pipe 32 fixed to the bottom of the tank 1. A discharge pipe 11 is fixedly connected to and communicates with the connecting pipe 32 through the bottom of the tank 1. An oil drain hole 33 is opened on the connecting pipe 32 near the bottom of the tank 1. A lifting ring 9 for sealing the oil drain hole 33 is sleeved on the connecting pipe 32. A fixing plate 91 is fixed on the lifting ring 9. A hydraulic rod 92 is fixed to the bottom of the tank 1. The telescopic end of the hydraulic rod 92 passes through the bottom of the tank 1 and is connected to the fixing plate 91 through a short rod. A corrugated pipe 93 is fixed between the bottom of the fixing plate 91 and the bottom of the tank 1. The telescopic end of the hydraulic rod 92 is located inside the corrugated pipe 93. The oil entering the shell 2 first enters the folded pipe 31, then the connecting pipe 32, and is subsequently discharged through the discharge pipe 11, which is also equipped with a solenoid valve. When the water in the tank 1 is completely drained and the folded pipe 31 is compressed to its limit, and the shell 2 can no longer move downward, the hydraulic rod 92 can be activated to drive the lifting ring 9 to move upward, opening the oil drain hole 33. The oil in the tank 1 then enters the connecting pipe 32 through the oil drain hole 33 and is discharged through the discharge pipe 11. In conjunction with the discharge pipe 12, the discharge efficiency of the remaining oil in the tank 1 can be further improved. The bellows 93 can be stretched and compressed to prevent the hydraulic rod 92 from contacting the oil-water mixture in the tank 1.

[0020] like Figure 1 and Figure 2 As shown, a collection cylinder 43 covering the through hole 42 is fixed to the outside of the cylinder 4. The collection cylinder 43 can collect water discharged through the through hole 42 on the cylinder 4, and an oil-absorbing blanket (the same as the oil-absorbing blanket in the prior art) can also be installed inside the collection cylinder 43.

[0021] like Figure 1 and Figure 4 As shown, the top surface of the moving ring 8 is inclined, and a leakage hole is provided on the moving ring 8. The top surface of the moving ring 8 is inclined so that when the housing 2 moves downward to sample the oil-water mixture, the moving ring 8 moves downward and enters the oil-water mixture. When the housing 2 moves upward and returns to its original position, it cooperates with the leakage hole to allow the oil on the top surface of the moving ring 8 to drip downward more effectively.

[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
