Description

Technical Field

[0001] The invention relates to the field of dichloropinacolone desolvation processing, and in particular to a dichloropinacolone desolvation tower device. Background Art

[0002] "Desolventization" usually refers to the process of separating the solute from the solvent by some method. However, when it comes to the desolventization of dichloropinacolone, dichloropinacolone is added to the desolventizing tower for processing. The desolventizing tower is mainly used in the oil processing industry to remove the residual solvent in the degummed and leached oil to meet the finished oil standards. The desolventizing process is mainly based on the principle of steam distillation and is carried out under vacuum conditions.

[0003] The announcement number is CN210584890U, a chloropinacolone demelting and heating reactor, characterized in that it includes a reactor body, a metal protective layer and a chlorine gas guide tube; in the utility model, a water bath interlayer is formed between the outer side of the cylinder and the metal protective layer of the cylinder, and a plurality of groove structures for accommodating hot water are used in the water bath interlayer to ensure that the temperature in the reactor is very constant, thereby avoiding the problem of pinacolone carbonization caused by a steam full-contact heating method, and by punching a plurality of holes in the outer contour of the guide tube at an angle of 25° to the guide tube, so that the reaction gas enters the inner wall of the guide tube from the outer wall of the guide tube through the spiral hole. Due to the shape and design of the spiral hole, the gas entering from the outer wall of the guide tube will spirally rise, and after leaving the guide tube, the gas moves in a spiral path, and the full contact is beneficial to the full contact reaction of the gas in the reactor.

[0004] In the existing desolventizing process of dichloropinacolone, since dichloropinacolone needs to be heated, the existing heating method generally transports high-temperature gas to the desolventizing tower through a spiral pipe for reaction. However, in the actual operation, due to the large internal space of the desolventizing tower, the heat source on the inner wall of the desolventizing tower cannot be quickly transmitted to the center, resulting in a good reaction of dichloropinacolone at the periphery and a poor reaction of dichloropinacolone at the center. In addition, the reaction requirements of dichloropinacolone are relatively special, and the inside of the desolventizing tower needs to be extracted into a vacuum environment. However, after dichloropinacolone is added to the inside of the desolventizing tower, it forms an accumulation situation, and there will be a certain gap inside the desolventizing tower. The vacuum extraction cannot ensure that the inside of the accumulated dichloropinacolone is in a vacuum state, thereby affecting the desolventizing process of dichloropinacolone.

[0005] Therefore, it is necessary to invent a dichloropinacolone desolventizing tower device to solve the above problems. Summary of the invention

DETAILED DESCRIPTION

[0030] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0031] The present invention provides Figure 1-7 A dichloropinacolone desolventizing tower device is shown, comprising a desolventizing tower 001, a feed pipe 101 is connected through the top of the desolventizing tower 001, a discharge pipe 104 is connected through the bottom of the desolventizing tower 001, a plurality of support legs 102 are installed at the bottom of the desolventizing tower 001, and a pressure relief valve 103 is connected through one side of the desolventizing tower 001;

[0032] A uniform heating component 002 is disposed inside the desolventizing tower 001 and is used to uniformly heat the dichloropinacolone;

[0033] The stirring and emptying component 003 is arranged inside the desolventizing tower 001 and is used to stir the dichloropinacolone.

[0034] Furthermore, in the above structure, the uniform heating component 002 includes a connecting column 201, which is installed below the inner wall of the desolventizing tower 001. A threaded through groove 1 202 is provided on the surface of the connecting column 201, and a threaded through groove 203 is provided on the inner wall of the desolventizing tower 001, and the threaded through groove 203 is connected with the threaded through groove 1 202.

[0035] By connecting the column 201 and the desolventizing tower 001 , an annular space is formed at the lower part of the desolventizing tower 001 .

[0036] Furthermore, in the above structure, a spiral tube 204 is installed in the threaded groove 1 202 and the threaded groove 2 203, and one side of the spiral tube 204 is exposed.

[0037] Since a part of the spiral tube 204 is exposed, when the high-temperature medium passes through the interior of the spiral tube 204, the exposed spiral tube 204 can transfer heat to the dichloropinacolone, thereby achieving heating. In addition, due to the special shape of the spiral tube 204, it can be ensured that the dichloropinacolone can be heated evenly, and the length of the spiral tube 204 can ensure that the passage time of the medium is extended, thereby improving the heat conversion rate.

[0038] Furthermore, in the above structure, the stirring and emptying assembly 003 includes a motor 301 , which is installed above the desolventizing tower 001 , and an output shaft 302 is installed at the output end of the motor 301 , and the output shaft 302 is arranged in the desolventizing tower 001 .

[0039] The motor 301 can drive the output shaft 302 to rotate inside the desolventizing tower 001 .

[0040] Furthermore, in the above structure, a connecting cavity 303 is provided at the bottom of the output shaft 302, and a limiting groove 304 is symmetrically provided on the inner wall of the connecting cavity 303. A docking column 305 is connected through the connecting cavity 303, and a limiting block 306 is symmetrically installed on the docking column 305, and the limiting block 306 is slidably connected to the limiting groove 304.

[0041] Through the cooperation between the limiting block 306 and the limiting groove 304 , the docking column 305 can slide within the connecting cavity 303 .

[0042] Furthermore, in the above structure, a connecting block 307 is installed below the docking column 305 , a spring 316 is sleeved on the docking column 305 , and the upper part of the spring 316 is in contact with the output shaft 302 , and the lower part of the spring 316 is in contact with the connecting block 307 .

[0043] The position of the docking post 305 in the connecting cavity 303 can be maintained by the spring 316 .

[0044] Furthermore, in the above structure, an annular fixing frame 308 is installed on the connecting block 307, and the connecting block 307 is located at the center of the annular fixing frame 308. A plurality of stirring rods 309 are installed in a circular distribution below the annular fixing frame 308, and a wave cylinder 310 is installed at the center below the annular fixing frame 308.

[0045] The annular fixing frame 308 can simultaneously drive the multiple groups of stirring rods 309 to rotate, so that the multiple groups of stirring rods 309 stir the dichloropinacolone, so that the dichloropinacolone can be evenly heated, and the excess air inside can be discharged in time during the stirring process.

[0046] Furthermore, in the above structure, a slide bar 311 is installed at the center position below the annular fixing frame 308 , and the slide bar 311 is sleeved with the wave cylinder 1 310 , and a limit ring 312 is sleeved and fixed below the slide bar 311 .

[0048] By rotating the wave cylinder 1 310 along the wave cylinder 2 315, the wave cylinder 1 310 generates up and down vibrations, ensuring that the stirring rod 309 can stir the dichloropinacolone up and down, effectively discharge the excess air inside it, and the cooperation between the annular cavity 314 and the limiting ring 312 can ensure the stable cooperation between the docking cylinder 313 and the sliding rod 311.

[0049] like Figure 1-7 As shown, dichloropinacolone is added into the desolventizing tower 001 through the feed pipe 101, so that the dichloropinacolone can be accumulated in the annular space below the desolventizing tower 001. At this time, the output shaft 302 is driven to rotate by the motor 301, so that the annular fixing frame 308 drives the stirring rod 309 to rotate while vibrating up and down to a certain extent, thereby discharging the air remaining in the dichloropinacolone and ensuring the vacuum environment inside the desolventizing tower 001. At this time, the heating box 205 can transport the heated medium into the spiral tube 204, so as to heat the dichloropinacolone, and the stirring rod 309 will continue to stir during the heating process, so that the dichloropinacolone is evenly heated, thereby improving the desolventizing efficiency and quality of the dichloropinacolone.
