In the description of the present application, the meaning of "several" is at least two, such as two, three, etc., unless otherwise specifically limited.

[0031] The present application will be further described in detail below in conjunction with the drawings and embodiments:

[0032] As shown in Figure 1 , 2 An oil extraction device for viscous materials, comprising a horizontal extraction tank 1 and a condensation system 5 arranged on one side of the upper end of the extraction tank 1; a rotating shaft 11 is arranged inside the extraction tank 1, a plurality of stirring paddles 12 are arranged on the rotating shaft 11, and a plow assembly 13 is arranged at the end of each stirring paddle 12; a plurality of liquid outlets 18 and a plurality of side mirrors 17 (i.e. one liquid outlet 18 is arranged corresponding to one side mirror 17) are arranged in parallel on one side of the extraction tank 1; the side mirror 17 and the liquid outlet 18 are located on the same horizontal line; the condensation system 5 comprises a condensation pipeline arranged at the upper end of the extraction tank 1, a cladding interlayer 51 is arranged outside the inlet of the condensation pipeline and is in communication with a cooling water system, and a filter screen 52 is arranged inside the inlet of the condensation pipeline.

[0033] Specifically:

[0034] (1) After the oil extraction is completed, the material will sink to the bottom of the tank, and the oil extraction solvent will float on the upper layer of the tank body, as shown in Figure 1, 2 As shown, this utility model has three liquid outlets 18 and three corresponding sight glasses. The height of the extraction solvent can be observed through the side sight glass 17. The valves corresponding to the liquid outlets 18 can be selectively switched to drain the extraction solvent, reducing the amount of extraction solvent remaining in the material. In this way, viscous materials do not need to be discharged after one extraction. After draining the extraction solvent, new solvent can be added directly to the same extraction tank 1 for a second extraction, which can also solve the problem of incomplete extraction solvent discharge.

[0035] (2) In the conventional condensation system operation process, during the thorough mixing of solvent and material, the solvent evaporates into the condensation pipeline, condenses into a liquid state through the heat exchanger and is stored in the condensate tank, and then pumped back to the extraction tank. This multi-operation process can easily lead to solvent loss and an imbalance in the material-liquid ratio in the extraction system. For example Figure 1 As shown, this invention provides a jacketed layer 51 on the outside of the condenser pipe inlet of the extraction tank, which can be filled with circulating water or chilled water to cool the gas phase (the jacketed layer 51 is connected to the cooling water system, and is filled with cooling water or chilled water, so that the extraction solvent can be directly condensed into the extraction tank 1 during the oil extraction mixing process to maintain the solvent balance of the oil extraction system). This allows the solvent to evaporate into the condenser pipe during the solvent extraction process, and then directly condense into liquid and return to the extraction tank, effectively ensuring that the solvent is directly condensed into the extraction tank, reducing losses and imbalance of the material-liquid ratio.

[0036] (3) Due to its high viscosity, viscous materials have poor fluidity and are prone to settling to the bottom of the tank. After adding the oil extraction solvent, the driving agitator has difficulty penetrating the solvent into the material, and the oil extraction effect is not ideal. This utility model installs multiple plow blade components 13 with triangular tip structures on the agitator 12, which can better cut the material during the oil extraction process, so that the solvent and the material can come into more full contact and mix, thereby improving the oil extraction effect.

[0037] (4) During the high-speed mixing and depressurization solvent removal process, the material will flow to the condenser pipe with the airflow. A filter screen is installed at the inlet of the condenser pipe to effectively intercept the material that flows into the condenser pipe with the airflow, thus preventing and reducing material loss.

[0038] Furthermore, the oil extraction equipment also includes a transmission mechanism 12 capable of driving the rotating shaft 11 to rotate. The transmission mechanism 2 is located on the other side of the extraction tank 1. The transmission mechanism includes a motor 21, a belt 22, and a pulley 23. The transmission method of the transmission mechanism 2 is motor-belt rotation, which has a simple structure and low maintenance cost. It is suitable for high-speed transmission and meets the requirements of high-power motors for mixing viscous materials.

[0039] Further, the tank body of the extraction tank 1 is provided with a jacket; hot water can be passed through the jacket to heat the material, or circulating water can be passed through the jacket to cool the material. The oil extraction equipment is provided with a temperature control system 4 capable of heating or cooling the extraction tank 1.

[0040] Further, the top of the extraction tank 1 is provided with a sight glass 14, a manhole 15, and a liquid inlet 16.

[0041] Further, as shown in Figure 3 The inner side of the sight glass 14 is provided with a four-fluorine scraper 141 for scraping off the material on the glass surface (the material splashed onto the sight glass) to facilitate observation of the oil extraction situation in the extraction tank 1.

[0042] Further, as shown in Figure 1 A first manual ball valve 161 is also provided on the liquid inlet pipeline connected to the liquid inlet 16 for controlling the amount of oil extraction solvent and facilitating personnel operation.

[0043] Further, the oil extraction equipment also includes a discharge control system 3 provided at the bottom of the extraction tank 1, which at least includes a pneumatic butterfly valve 31 and a second manual ball valve 32 provided at the inlet and outlet.

[0044] Further, the pneumatic butterfly valve 31 is installed above the second manual ball valve 32. The pneumatic butterfly valve 31 can realize automatic control of the discharge and facilitate adjustment; the second manual ball valve 32 is installed at the bottom of the pneumatic butterfly valve 31 to facilitate control of the discharge flow of the viscous material after oil extraction.

[0045] Further, the mesh size of the filter screen 52 is 100-300 meshes. The provision of the filter screen 52 can prevent the material from flowing into the condensing pipeline with the gas stream during high-speed mixing and pressure reduction to remove the solvent, thereby reducing the loss of the material.

[0046] Further, the condensing system 5 also includes a heat exchanger 53, a condensate tank 54, and a vacuum pump 55; the heat exchanger 53 and the condensate tank 54 are installed at the end of the condensing pipeline; a vacuum pipeline connected to the vacuum pump 55 is installed at the top of the condensate tank 54. The heat exchanger 53 is used to condense the volatile oil extraction solvent, the condensate tank 54 is used to store the condensed oil extraction solvent, and the vacuum pipeline and the vacuum pump 55 are used to provide the required negative pressure when the material removes the oil extraction solvent.

[0047] Method for use:

[0048] Before the oil extraction device starts to work, the power is turned on in advance, and the transmission mechanism 2 and the vacuum pump 55 are checked to determine whether they can operate normally. After determining that the oil extraction device can operate normally, the extraction tank 1 is filled with negative pressure, and then the pneumatic butterfly valve 31 and the manual ball valve 32 are opened, and the viscous material is started to be pumped in. The amount of viscous material pumped in is selected according to the amount of oil extraction solvent. After the pumping in is completed, the second manual ball valve 32 and the pneumatic butterfly valve 31 are closed in turn, the vacuum pump 55 is closed, the required amount of solvent is added from the liquid inlet 16, and the first manual ball valve 161 is closed.

[0049] When the oil extraction starts, the viscous material and the oil extraction solvent are fully mixed under the shearing and stirring of the stirring paddle 12 and the plow assembly 13, and the oily components in the viscous material are dissolved in the oil extraction solvent. During the mixing, the condensing system 5 is opened, circulating water or chilled water is introduced into the cladding sandwich 51, and the volatile oil extraction solvent can be directly condensed into the extraction tank 1. At the same time, the heat exchanger 53 is connected to circulating water, which further prevents the loss of oil extraction solvent.

[0050] The extraction tank 1 selectively opens the temperature control system 4 according to the process conditions to maintain the balance of the solvent amount. After a certain period of time, the transmission mechanism 2 is closed and the stirring and mixing are stopped. At this time, the viscous material (excluding the extracted oily components) will sink to the bottom of the tank, and the oil extraction solvent will float on the material. This can be observed through the top sight glass 14.

[0051] After the static state is ended, the oil extraction solvent can be discharged. The solid-liquid separation condition can be observed in advance from the side sight glass 17, and then the liquid outlet 18 valves are opened from top to bottom in turn. If the uppermost valve is opened first, the oil extraction solvent will flow out of the liquid outlet 18 to the storage tank 6. When it is observed that the same horizontal sight glass 17 does not show the solvent level and no liquid is discharged, the valve is closed, the next layer valve is opened, and so on, until the oil extraction solvent is completely discharged, and all the valves of the liquid outlet 18 are closed. Thus, the first oil extraction is completed, and the selective multiple oil extraction is repeated.

[0052] After the oil extraction is completed, the transmission mechanism 2, the vacuum pump 55 and the temperature control system 4 are opened, and the cooling water system connected to the cladding sandwich 51 is closed. Under the conditions of negative pressure and temperature rise, the viscous material rolls in the extraction tank 1, the oil extraction solvent wrapped therein becomes a gas phase, is condensed into the condensate tank 54 through the heat exchanger 53, and achieves the purpose of removing the oil extraction solvent from the material.

[0053] After the oil extraction solvent is removed, other solvents can be continuously added from the liquid inlet 16, or the material can be discharged from the tank bottom discharge control system 3. There are many optional operations, and the user can select according to the product and production process.

[0054] Finally, it should be noted that: the above embodiments are used to illustrate the technical solutions of the present application, but not limited to them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement to part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
