Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] like Figures 1 to 8 As shown, in the embodiment of the present invention, a heavy alkylbenzene sulfonic acid composite oil-displacing agent decolorizing device comprises a decolorizing tank body 1, a feed pipe 2 is fixedly installed on the top of the decolorizing tank body 1, a discharge pipe 3 is fixedly connected to one side of the decolorizing tank body 1, a protective door 17 is hinged on the other side of the decolorizing tank body 1, and a stirring assembly is arranged inside the decolorizing tank body 1;

[0034] The stirring assembly includes a stirring shaft 4 arranged inside the decolorizing tank 1, a connecting rod 5 is fixedly installed on the outer wall of the stirring shaft 4, and the connecting rods 5 are evenly distributed in a ring array. A plurality of stirring blades 6 are installed on the outer wall of the stirring shaft 4, and a separation assembly is arranged below the stirring blades 6;

[0035] The outer wall at the top of the stirring shaft 4 is rotatably connected to a second gear 10, one side of the second gear 10 is meshedly connected to a first gear 9, a first rotating shaft 8 is fixedly mounted on the inner wall of the first gear 9, and a motor 7 is mounted on the top of the first rotating shaft 8;

[0036] The separation component includes a filter frame 13 arranged below the stirring blade 6, a mixing component is arranged inside the filter frame 13, a filter plate 14 is arranged at the bottom end of the filter frame 13, filter holes 16 are opened on the inner walls of the filter frame 13 and the filter plate 14, a cylinder 15 is installed at the bottom end of the filter plate 14, and the cylinder 15 is arranged at the bottom of the decolorization tank 1.

[0037] When the oil-displacing agent is subjected to decolorization treatment, the material is firstly put into the decolorization tank body 1 from the feed pipe 2, and then the motor 7 is started. When the motor 7 is started, the first rotating shaft 8 is driven to rotate, and the rotation of the first rotating shaft 8 drives the rotation of the first gear 9, and the rotation of the first gear 9 drives the rotation of the second gear 10, and the rotation of the second gear 10 drives the rotation of the stirring shaft 4, and the rotation of the stirring shaft 4 drives the rotation of the stirring blade 6, so that the stirring blade 6 rotates in the decolorization tank body 1 to mix the material;

[0038] After mixing, the motor 7 is turned off, and the decolorization reaction is carried out according to the preset reaction time. During the reaction, the decolorizing agent gradually sinks to the bottom and is stored in the filter frame 13;

[0039] When secondary decolorization is required, the filter plate 14 is driven upward by the cylinder 15, and the movement of the filter plate 14 drives the movement of the filter frame 13, so that the filter frame 13 moves upward with the decolorizer, and the oil-displacing agent is filtered out through the filter hole 16;

[0040] When the filter frame 13 moves up to one side of the protection door 17, the protection door 17 is opened, the filter frame 13 is taken out, and the decolorizing agent inside the filter frame 13 is replaced. After replacement, the filter frame 13 is placed on the top of the filter plate 14 again, and the filter plate 14 is driven downward by the cylinder 15 to immerse the filter frame 13 in the oil-displacing agent for secondary decolorization to improve the convenience of operation.

[0041] like Figure 2 , Figure 4 and Figure 8 As shown, the lowest stirring blade 6 is fixedly connected to the stirring shaft 4, and the other stirring blades 6 are slidably connected to the stirring shaft 4.

[0042] When the filter frame 13 moves up and contacts the stirring blade 6 at the bottom, the filter frame 13 drives the stirring blade 6 to move up. When the stirring blade 6 at the bottom moves up, it contacts several stirring blades 6 above and drives the stirring blades 6 above to move up, so that all the stirring blades 6 on the outer wall of the stirring shaft 4 are stacked up, thereby providing space for the filter frame 13 to move up.

[0043] like Figures 1 to 4 As shown, the top end of the connecting rod 5 is embedded in the top of the decolorizing tank 1 and is slidably connected.

[0044] When the filter frame 13 and the stirring blade 6 move upward, the top of the stirring shaft 4 slides out of the device.

[0045] like Figure 2 , Figure 3 , Figure 4 and Figure 8As shown, each group of stirring blades 6 are connected by a block 19 and a slot 20, the block 19 is fixedly installed on the top of the stirring blade 6, the slot 20 is opened at the bottom of the stirring blade 6, and a connecting plate 21 is fixedly installed on the top of the uppermost stirring blade 6. A connecting ring 11 is arranged above the connecting plate 21, and the connecting ring 11 is installed on the inner wall of the decolorizing tank 1.

[0046] The connecting plate 21 is magnetically connected to the connecting ring 11, and the clamping block 19 is magnetically connected to the clamping slot 20;

[0047] When the stirring blades 6 are moved up and stacked, several stirring blades 6 are engaged and magnetically connected through the block 19 and the slot 20, and the connecting plate 21 of the top stirring blade 6 contacts and magnetically connects with the bottom end of the connecting ring 11, so that several stirring blades 6 are stably stacked at the top inside the decolorization tank 1, which facilitates the replacement of the filter frame 13.

[0048] like Figure 2 , Figure 3 , Figure 4 and Figure 8 As shown, a connecting rope 12 is fixedly connected between each group of stirring blades 6, and a connecting rope 12 is also fixedly connected between the connecting plate 21 and the connecting ring 11, and the connecting ropes 12 are evenly distributed in a ring array.

[0049] The distance between each stirring blade 6 is limited by the connecting rope 12;

[0050] The bottom stirring blade 6 is magnetically connected to the top of the mixing plate 23;

[0051] After the filter frame 13 is replaced, the filter frame 13 is placed on the top of the filter plate 14 again, so that the mixing plate 23 is located at the bottom of the stirring blade 6. The filter frame 13 is moved downward through the magnetic connection between the two, driving the stirring blade 6 to move downward, and the connecting rope 12 is used to limit the position of the several stirring blades 6 to be separated and reset, so as to facilitate the subsequent mixing of the materials.

[0052] like Figure 2 and Figure 3 As shown, the connecting ring 11 is rotatably connected to the decolorizing tank body 1.

[0053] When the stirring blade 6 rotates to stir the materials, the connecting ring 11 also rotates in the inner wall of the decolorizing tank 1 to prevent the connecting rope 12 from getting tangled when the stirring blade 6 rotates to mix.

[0054] like Figure 2 and Figure 3 As shown, the connecting ring 11 is arranged on the outer wall of the stirring shaft 4 , and the connecting ring 11 and the stirring shaft 4 are slidably connected.

[0055] like Figure 2 and Figure 7As shown, the mixing assembly includes a mixing plate 23 disposed inside the filter frame 13 , a second rotating shaft 22 is fixedly connected to the bottom end of the mixing plate 23 , and the second rotating shaft 22 is rotatably mounted on the inner wall of the filter frame 13 .

[0056] When the decolorizing agent inside the decolorizing tank 1 is taken out, the motor 7 can be started to rotate the stirring shaft 4 at a low speed. The magnetic connection between the stirring blade 6 and the mixing plate 23 drives the mixing plate 23 to rotate at a low speed, so that the mixing plate 23 stirs the decolorizing agent and the oil-displacing agent inside the filter frame 13, making it easier for the oil-displacing agent to be discharged from the filter hole 16, thereby improving the separation efficiency.

[0057] like Figure 7 As shown, the inner wall of the mixing plate 23 is evenly provided with protrusions 24 , and the top of the protrusion 24 is provided with a spring 25 .

[0058] The bottom end of the protrusion 24 is provided with a curved surface;

[0059] The elastic potential energy of the spring 25 makes the protrusion 24 always tend to move downward. When the mixing plate 23 rotates, the protrusion 24 produces a knocking effect on the filter frame 13, which can not only prevent the filter hole 16 from being blocked but also further improve the separation efficiency.

[0060] like Figure 5 and Figure 6 As shown, a rotating ring 26 is rotatably connected to the filter hole 16 opened on the inner wall of the filter plate 14 , and a turbine blade 27 is fixedly installed on the inner wall of the rotating ring 26 .

[0061] When the materials are separated, the oil-displacing agent enters the filter holes 16 inside the filter plate 14 and drives the turbine blades 27 to rotate. The power generated by the rotation can help the oil-displacing agent pass through the filter holes 16 faster, thereby improving the overall separation efficiency.

[0062] Working principle and usage process:

[0063] When the oil-displacing agent is subjected to decolorization treatment, the material is firstly put into the decolorization tank body 1 from the feed pipe 2, and then the motor 7 is started. When the motor 7 is started, the first rotating shaft 8 is driven to rotate, and the rotation of the first rotating shaft 8 drives the rotation of the first gear 9, and the rotation of the first gear 9 drives the rotation of the second gear 10, and the rotation of the second gear 10 drives the rotation of the stirring shaft 4, and the rotation of the stirring shaft 4 drives the rotation of the stirring blade 6, so that the stirring blade 6 rotates in the decolorization tank body 1 to mix the material;

[0064] After mixing, the motor 7 is turned off, and the decolorization reaction is carried out according to the preset reaction time. During the reaction, the decolorizing agent gradually sinks to the bottom and is stored in the filter frame 13;

[0065] When secondary decolorization is required, the filter plate 14 is driven upward by the cylinder 15, and the movement of the filter plate 14 drives the movement of the filter frame 13, so that the filter frame 13 moves upward with the decolorizer, and the oil-displacing agent is filtered out through the filter hole 16;

[0066] The movement of the filter frame 13 drives the movement of the mixing plate 23. When the mixing plate 23 moves to the bottom end of the stirring blade 6, the two are magnetically connected. At the same time, the stirring shaft 4 is controlled by the motor 7 to rotate at a low speed to drive the stirring blade 6 to rotate. The rotation of the stirring blade 6 drives the rotation of the mixing plate 23. Through the elastic potential energy of the spring 25, the protrusion 24 produces a knocking effect on the filter frame 13 to separate the materials.

[0067] The filter frame 13 moves upward to drive the stirring blades 6 to move upward, and the several stirring blades 6 are magnetically connected to each other through the clamping block 19 and the clamping groove 20, and the connecting plate 21 of the top stirring blade 6 is in contact with the bottom end of the connecting ring 11 to be magnetically connected, so that the several stirring blades 6 are stably stacked on the top of the decolorizing tank 1;

[0068] When the filter frame 13 moves up to one side of the protection door 17, the protection door 17 is opened, the filter frame 13 is taken out, and the decolorizing agent inside the filter frame 13 is replaced. After replacement, the filter frame 13 is placed on the top of the filter plate 14 again, and the filter plate 14 is driven downward by the cylinder 15 to immerse the filter frame 13 in the oil-displacing agent for secondary decolorization;

[0069] After decolorization, the cylinder 15 is started again to move the filter plate 14 and the filter frame 13 upward for a distance, and the discharge pipe 3 is opened to discharge the material.

[0070] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
