Description

Technical Field

[0001] The utility model relates to the technical field of oil-water separation, and particularly relates to a combined oil-water separation device. Background Art

[0002] Tea oil, commonly known as camellia seed oil, also known as camellia oil and camellia seed oil, is a pure natural high-grade edible vegetable oil extracted from the mature seeds of Camellia oleifera Abel, a plant of the genus Camellia in the family Theaceae. It is golden yellow or light yellow in color, pure in quality, clear and transparent, with a delicate fragrance and a pure taste. Camellia oleifera is commonly known as camellia, wild tea, and white-flowered tea, and is a unique high-quality oil-bearing plant in China. Camellia oleifera and tea belong to the same genus but different species, and the vegetable oils extracted from their seeds are completely different. The former is called camellia seed oil, and the latter is called tea seed oil.

[0003] To extract tea oil from tea seeds, basically the pressing method is adopted. First, the tea seeds are crushed and ripened, and then the cooked materials are pressed by a press to produce crude oil. The crude oil is processed and filtered to finally produce tea oil. However, it is very difficult to completely squeeze out the tea oil in the oil cake by this extraction method, and the oil residue will still contain a certain amount of tea oil. In order to extract the residual oil in the oil residue, most of the existing technologies use a centrifuge to further centrifuge and filter the oil residue. However, the existing centrifuges have low use efficiency, it is very difficult to completely extract the tea oil in the oil residue, and the extraction speed is also slow. Content of the Utility Model

[0004] In view of the technical defects in the background art, the utility model provides a tea residue residual oil separation device, which solves the above technical problems and meets the actual needs. The specific technical solutions are as follows:

[0005] A tea residue residual oil separation device includes an oil-water separation tank body and a water-cooled tank body arranged on one side of the oil-water separation tank body.

Specific embodiments

[0021] The following combines the drawings with related embodiments to illustrate the implementation manners of the present utility model. The implementation manners of the present utility model are not limited to the following embodiments, and the relevant necessary components involved in the present utility model should be regarded as well-known technologies in the technical field, which can be known and mastered by those skilled in the technical field.

[0022] As Figures 1 to 3 shown, an oil separation device for tea seed cake residues includes an oil-water separation tank body 1 and a water-cooled tank body 2 arranged on one side of the oil-water separation tank body 1. A circulation pipeline 3 is provided between the oil-water separation tank body 1 and the water-cooled tank body 2. A water-cooled chamber 9 communicating with the water-cooled tank body 2 is provided on the outer layer of the oil-water separation tank body 1. A stirring assembly 4 and a heating assembly 5 are provided inside the oil-water separation tank body 1. A first filter layer 6 and a second filter layer 7 are arranged in sequence from top to bottom along the height direction of the oil-water separation tank body 1, so as to divide the oil-water separation tank body 1 into a first chamber 101, a second chamber 102 and a third chamber 103 from top to bottom. The stirring assembly 4 is provided with stirring rollers 403 corresponding to the second chamber 102 and the third chamber 103, and an oil pumping assembly 8 is provided in the first chamber 101.

[0023] When the utility model is in use, the oil-water separation tank body 1 is separated by a first filter screen layer 6 and a second filter screen layer 7 into a first chamber 101, a second chamber 102 and a third chamber 103 which are arranged in sequence from top to bottom. Among them, the tea seed cake after extrusion and oil pressing is placed in the second chamber 102. Water is injected into the oil-water separation tank body 1 so that the water level is higher than the horizontal height of the first filter screen layer 6. The tea seed cake in the second chamber 102 forms a mixture after being injected with water. Water can help the grease to be released from the tea seed cake. Especially during the heating process, the heat energy of water helps the extraction of grease. The water in the tank body is heated to 80°C - 100°C through the heating component 5, so that the grease floats to the water surface through the first filter screen layer 6, and the floating oil is collected through the oil pumping component 8 and output through the oil outlet 105;

[0024] It should be noted that after the water in the tank body is heated to 80°C - 100°C through the heating component 5, most of the grease is separated from the tea seed cake, but there will still be a phenomenon that some grease does not separate immediately after being mixed with water. The liquid in the water-cooled tank body 2 is circulated to the water-cooled chamber 9 through the circulation pipeline 3 and cooled to 40°C, which can cool the mixture. The grease will solidify due to the temperature reduction, making it easier to separate from the water.

[0025] In the structure of the oil-water separation tank body 1 of the utility model, the oil-water separation tank body 1 is successively provided with a first chamber 101, a second chamber 102 and a third chamber 103 from top to bottom. The first chamber 101, the second chamber 102 and the third chamber 103 are separated by a first filter screen layer 6 and a second filter screen layer 7. The pore diameters of the first filter screen layer 6 and the second filter screen layer 7 are 1 - 2 mm. After the tea seed cake is placed in the second chamber 102 and injected with water, the first filter screen layer 6 and the second filter screen layer 7 separate the tea seed cake from the first chamber 101 and the third chamber 103 and cannot enter the first chamber 101 and the third chamber 103; The grease can enter the first chamber 101 through the pores of the first filter screen layer 6. The mixture in the second chamber 102 is fully mixed under the rotation of the stirring component 4, so that the grease in the mixture is separated more fully. Further, the floating scum in the mixture cannot pass through the second filter screen layer 7 and enter the third chamber 103, which is convenient for fully extracting the grease and subsequent cleaning;

[0026] Furthermore, in the structure of the oil-water separation tank body 1, a packing port 106 is provided on the outer surface of the oil-water separation tank body 1 corresponding to the position of the second chamber 102. A sealing cover 107 for screwing and sealing is provided at the opening of the packing port 106. During packing, the oil-water separation tank body 1 is in a waterless state. By screwing the sealing cover 107 and putting camellia seed cake into the second chamber 102 through the packing port 106, the packing is completed. After the separation is completed, the mixture is discharged through the packing port 106 and the tank body is cleaned. Temperature monitors are provided in both the first chamber 101 and the second chamber 102 of the oil-water separation tank body 1, which can accurately control the liquid temperature in the tank during heating and cooling, and achieve the purpose of quickly separating oil through heating assistance, while avoiding local overheating leading to rapid boiling and splashing of the oil.

[0027] In the structure of the stirring assembly 4 of the present utility model, a cover body 104 is provided at the top of the oil-water separation tank body 1. The stirring assembly 4 includes a driving motor 401 provided in the middle of the cover body 104, a rotating rod body 402 whose end is fixed to the output end of the driving motor 401, and several stirring rollers 403 connected to the rotating rod body 402.

[0028] Furthermore, in the above solution, the output end of the driving motor 401 is vertically downwardly provided on the cover body 104. The rotating rod body 402 vertically downwardly passes through the first filter layer 6 and the second filter layer 7 in sequence. The first filter layer 6 and the second filter layer 7 are movably connected to the rotating rod body 402.

[0029] Furthermore, in the above solution, several stirring rollers 403 are equidistantly arranged circumferentially around the rotating rod body 402. At least two stirring rollers 403 on the same horizontal plane form a stirring group. At least one group of the stirring groups is provided in the second chamber 102 along the axial direction of the rotating rod body 402, and at least one group of the stirring groups is provided in the third chamber 103 along the axial direction of the rotating rod body 402.

[0030] It should be noted that after the camellia seed cake is filled into the second chamber 102 through the feeding port, water is injected to make the water level exceed the second chamber 102. The heating assembly 5 heats the water body. During the heating process, the driving motor 401 drives the rotating rod body 402 to rotate, and the rotating rod body 402 drives the stirring rollers 403 to rotate. While fully mixing the camellia seed cake and water by rotation, it ensures that the water body in the tank is in a uniformly heated state, so as to fully extract the oil in the camellia seeds under the hydrothermal environment.

[0031] Further, in the above solution, the heating assembly 5 is provided at the bottom of the third chamber 103. The heating assembly 5 is a coil heater, and the horizontal height of the connection position between the circulation pipeline 3 and the third chamber 103 is not lower than the horizontal height of the heating assembly 5.

[0032] In the circulation pipeline 3 structure of the present utility model, a circulation pipeline 3 is connected between the oil-water separation tank body 1 and the water-cooling tank body 2. The circulation pipeline 3 includes a water inlet pipeline 301, a water outlet pipeline 302, and a water pump 303. One end of the water inlet pipeline 301 is communicated with the water-cooling chamber 9, the other end of the water inlet pipeline 301 is connected to the water pump 303, the water outlet of the water pump 303 is communicated with the water-cooling tank body 2, and both ends of the water outlet pipeline 302 are respectively communicated with the water-cooling chamber 9 and the water-cooling tank body 2;

[0033] It should be noted that during the oil separation process, by heating, the fluidity of the oil can be increased, making it easier to separate from the tea seed cake. However, some oil will not separate immediately after mixing with water, and the process of heating and separation may need to be repeated multiple times to extract as much residual oil as possible. After completing a single heating and separation, the liquid in the water-cooling chamber 9 is pumped into the water-cooling tank body 2 through the water pump 303. The water in the water-cooling tank body 2 enters the water-cooling chamber 9 through the water outlet pipeline 302 for cooling, which can cool the oil-water mixture in the first chamber 101 and the second chamber 102. The oil will solidify due to the temperature drop, making it easier to separate from the second chamber 102 to under the first filter layer 6 and float to the water surface during secondary heating to extract as much residual oil as possible.

[0034] Further, in the above solution, the first chamber 101 is provided with an oil outlet 105. The oil outlet 105 is connected to the oil pumping assembly 8 through a pipeline. The oil pumping assembly 8 is an oil skimmer or an oil suction pump.

[0035] The above are only the preferred embodiments of the present utility model. It should be pointed out that for those of ordinary skill in the art of the present technology, without departing from the principle of the present utility model, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
