Description

Technical Field

[0001] The invention relates to the technical field of catalyst aging pretreatment, in particular to a rare earth butadiene rubber catalyst auxiliary aging device. Background Art

[0002] During the polymerization of butadiene rubber, the rare earth catalyst can ensure the polymerization rate of butadiene rubber. In order to ensure the activity of the rare earth catalyst, the rare earth catalyst needs to be aged.

[0003] Catalyst aging refers to treating the catalyst by calcination and other methods. The aging process can help the catalyst achieve optimal activity. Before aging, the rare earth catalyst should be in a dry and pure physical state to ensure its optimal catalytic performance. Therefore, before aging, the rare earth catalyst needs a rare earth catalyst auxiliary aging device to purify the catalyst. At present, the rare earth catalyst used in the production of butadiene rubber mainly includes a ternary catalyst system (composed of rare earth compounds, alkyl aluminum and chlorides), in which the main components of the chloride are cerium chloride and lanthanum chloride (both of the above two chlorides are soluble in water). Before aging the rare earth butadiene rubber catalyst, cerium chloride and lanthanum chloride also need to be purified.

[0004] The Chinese invention patent with announcement number CN107376953B discloses a method for recovering waste chromium-based fluorination catalysts. The waste chromium-based fluorination catalysts are used as raw materials. Through deep pressurized fluorination, chromium trioxide is fluorinated to chromium fluoride to the maximum extent. The fluorinated chromium trioxide is ground, dissolved in hydrofluoric acid, filtered, and the filtrate is purified to obtain high-purity chromium fluoride.

[0005] In this technical solution, the catalyst is crystallized by concentration and evaporation to facilitate recovery. However, in the concentration process of this technical solution, the steam generated is wasted. Therefore, it is necessary to continuously use solvents to dissolve the raw materials, resulting in high purification costs. In the process of purifying rare earth catalysts, there are many raw materials, and the purification of rare earth catalysts requires a long time and continuous work. The continuous addition of solvents will also increase the complexity of the purification work. Summary of the invention

DETAILED DESCRIPTION

[0068] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0069] Combine the following Figures 1 to 11 As shown, an embodiment of the present invention provides a rare earth butadiene rubber catalyst-assisted aging device, comprising:

[0070] A concentration tank 201, wherein a dissolving assembly is disposed on the top of the concentration tank 201, and the dissolving assembly is used to dissolve the raw material;

[0071] The evaporation tank 204 is arranged on the inner wall of the bottom of the concentration tank 201, and the evaporation tank 204 passes through the bottom of the concentration tank 201, and the bottom of the evaporation tank 204 is an open structure;

[0072] A sealing assembly, which is disposed at the bottom of the evaporation tank 204; the sealing assembly is used to seal the evaporation tank 204;

[0073] An evaporation component, which is disposed in the evaporation tank 204 and is used to concentrate the catalyst solution;

[0075] A flushing assembly, which is disposed in the evaporation tank 204 and is located above the filter assembly, and is used to flush catalyst crystals;

[0076] The recovery component is arranged on the side wall of the concentration tank 201, the recovery component is connected to the dissolution component, the recovery component is used to recover steam, and the recovery component is connected to the flushing component.

[0077] Further, the dissolving component comprises:

[0078] Dissolving tank 101, dissolving tank 101 is arranged on top of concentrating tank 201;

[0079] A net cylinder 102, which is disposed on the inner wall of the bottom of the dissolving tank 101 and is used to hold the catalyst raw material;

[0080] A fixing frame 103, the fixing frame 103 is fixed in the net cylinder 102, a water supply pipe 403 is fixed through the top of the fixing frame 103, a nozzle is arranged at the bottom of the water supply pipe 403, and the water supply pipe 403 is connected with the recovery component;

[0081] The heat exchange component is arranged in the dissolving tank 101, and the heat exchange component and the evaporation tank 204 are connected with the recovery component.

[0082] When the water in the water supply pipe 403 is output through the nozzle, a water flow is generated in the mesh cylinder 102, and the catalyst material in the mesh cylinder 102 is turned over by the water flow, which facilitates the dissolution efficiency of the catalyst.

[0083] Furthermore, the heat exchange component includes:

[0084] Two annular seats 301, both of which are fixed on the inner wall of the dissolving tank 101, and the two annular seats 301 are distributed up and down;

[0085] A plurality of heat exchange tubes 302 , wherein the plurality of heat exchange tubes 302 are disposed between the two annular seats 301 , and each heat exchange tube 302 is connected to the two annular seats 301 ;

[0086] A steam pipe 303, the steam pipe 303 is connected to the annular seat 301 located above, and the steam pipe 303 is connected to the evaporation tank 204;

[0087] The return pipe 404 is connected to the annular seat 301 below, and the return pipe 404 is connected to the recovery component.

[0088] When the steam passes through the heat exchange tube 302, the steam is liquefied, and the liquefied pure water enters the recovery component through the annular seat 301 below and the return pipe 404;

[0089] The heat released during the steam liquefaction process is absorbed by the solution in the dissolving tank 101, so that the temperature in the dissolving tank 101 increases, thereby further improving the dissolution efficiency of the catalyst.

[0090] Further, the flushing component includes:

[0091] A connecting seat 601, which is disposed in the evaporation tank 204, and a plurality of nozzles 602 are disposed through the side wall of the connecting seat 601;

[0092] The connecting tube 406 has one end connected to the connecting seat 601 and the other end connected to the recovery component.

[0093] When the pure water in the recovery component is output through the flushing component, the high-speed water flow output by the nozzle 602 rushes to the top of the filter component, flushes the catalyst crystals on the filter component, washes away the solution on the surface of the catalyst crystals, and ensures the purity of the catalyst.

[0094] Further, the recycling components include:

[0095] Cylinder 401, which is fixed on the side wall of the concentration tank 201, the return pipe 404 passes through the top inner wall of the cylinder 401, the connecting pipe 406 passes through the bottom of the outer wall of the cylinder 401, the water supply pipe 403 passes through the top inner wall of the cylinder 401, and the top and bottom of the cylinder 401 are both provided with mounting holes, and rubber membranes 405 are provided in the mounting holes;

[0096] One-way valve 407, the one-way valve 407 is arranged at the end of the water supply pipe 403, and the one-way valve 407 is fixed to the inner wall of the cylinder 401;

[0097] A piston 408, the piston 408 is slidably disposed in the cylinder 401;

[0098] A hydraulic push rod 402, the hydraulic push rod 402 is fixed to the top of the cylinder 401, and the output end of the hydraulic push rod 402 is fixed to the piston 408;

[0099] The third solenoid valve 409 is disposed through the piston 408 .

[0100] When the cylinder 401 is under low pressure, the piston 408 can move normally within a certain range through the deformation of the rubber membrane 405, so that the purified water recovered in the cylinder 401 can be squeezed and discharged;

[0101] After being squeezed, the pure water is output through the one-way valve 407 and the water supply pipe 403. The pure water can also enter the connecting seat 601 through the connecting pipe 406 and be output through the nozzle 602 to flush the catalyst.

[0102] Furthermore, it also includes:

[0103] A connecting pipe 202, which is disposed on the top of the concentration tank 201 and passes through the bottom inner wall of the dissolution tank 101;

[0104] The first solenoid valve 203 is fixed at the bottom end of the connecting pipe 202 , and the first solenoid valve 203 is located in the concentration tank 201 .

[0105] The solution in the dissolving tank 101 can enter the concentrating tank 201 through the connecting pipe 202 and the first electromagnetic valve 203 to prepare for the concentrating operation.

[0106] Further, the evaporation component comprises:

[0107] The evaporation plate 501 is disposed in the evaporation tank 204. A mounting hole is provided on the top of the evaporation plate 501. The evaporation plate 501 is a conical structure. An output hole is provided on the bottom of the evaporation plate 501.

[0108] A heating seat 502, the heating seat 502 is fixed in the mounting hole, and both side walls of the heating seat 502 are provided with fins 503;

[0109] The liquid extraction pipe 205 is arranged on the side wall of the evaporation tank 204 , and the liquid extraction pipe 205 is an L-shaped structure. A second solenoid valve 207 is arranged at the end of the liquid extraction pipe 205 , and the second solenoid valve 207 is located above the evaporation plate 501 .

[0110] When the heating seat 502 is working, the fins 503 on the upper surface of the heating seat 502 heat the solution on the evaporation plate 501 to concentrate the catalyst solution, so as to facilitate the crystallization of the catalyst.

[0111] Furthermore, the filtering component includes:

[0112] A bracket 701, the bracket 701 is disposed in the evaporation tank 204, and the bracket 701 and the evaporation tank 204 are detachably fixed;

[0113] An electric push rod 702, which is fixed on the top of the bracket 701;

[0114] A connecting frame 703, which is arranged on the output end of the electric push rod 702, and a plug 706 is arranged on the top of the connecting frame 703, and the plug 706 is adapted to the output hole;

[0115] The sealing ring 704 is fixed to the connecting frame 703, and the sealing ring 704 is in contact with the inner wall of the evaporation tank 204;

[0116] Filter paper 705, filter paper 705 and sealing ring 704 are fixed.

[0117] When the electric push rod 702 is switched on, the electric push rod 702 drives the plug 706 away from the evaporation plate 501 through the connecting frame 703 when working, so that the solution and the catalyst crystals on the evaporation plate 501 fall onto the filter paper 705 through the output hole. Due to the evaporation process, water vapor exists in the space above the filter paper 705 in the evaporation tank 204. Therefore, the air pressure above the filter paper 705 is greater than the air pressure below the filter paper 705. At this time, under the action of the air pressure difference on both sides of the filter paper 705, the concentrated solution passes through the filter paper 705, while the catalyst crystals remain on the filter paper 705.

[0118] Further, the sealing assembly comprises:

[0119] A sealing cover 206, which is disposed at the bottom of the evaporation tank 204;

[0120] The tube body 208 is disposed through the sealing cover 206, and a plurality of L-shaped tubes 209 are disposed on the side wall of the tube body 208, and each L-shaped tube 209 is connected to the tube body 208;

[0121] The output pipe 210 is disposed through the sealing cover 206 .

[0122] The specific working method is as follows: when in use, firstly, the vacuum device is connected to the tube body 208, and the switch of the third solenoid valve 409 is turned on. Then, the electric push rod 702 is operated to drive the connecting frame 703 to descend, so that the plug 706 on the connecting frame 703 is away from the evaporation plate 501. Finally, the switch of the vacuum device is turned on. When the vacuum device is working, the gas in the evaporation tank 204, the cylinder body 401, the two annular seats 301 and the plurality of heat exchange tubes 302 is extracted. Then, the electric push rod 702 is operated to make the plug 706 seal the output hole on the evaporation plate 501.

[0123] The catalyst raw material is introduced into the mesh cylinder 102, and pure water is injected into the dissolving tank 101. After a part of the catalyst is dissolved, the switch of the first electromagnetic valve 203 is turned on, so that the aqueous solution of the catalyst in the dissolving tank 101 enters the concentration tank 201 through the connecting pipe 202 and the first electromagnetic valve 203. In this process, the impurities insoluble in water are filtered by the mesh cylinder 102;

[0124] The switch of the second solenoid valve 207 is turned on. Under the effect of the negative pressure in the evaporation tank 204, the catalyst aqueous solution in the concentration tank 201 enters the evaporation tank 204 through the liquid extraction pipe 205 and the second solenoid valve 207 and stays on the evaporation plate 501. When the amount of aqueous solution on the evaporation plate 501 reaches a certain amount, the second solenoid valve 207 is closed.

[0125] The switch of the heating seat 502 is turned on. During the operation of the heating seat 502, the catalyst aqueous solution above the evaporation plate 501 is heated by the fins 503. Since the evaporation tank 204 is in a low pressure state at this time, the catalyst aqueous solution can also boil when the temperature is lower than 100 degrees Celsius, so that the water in the catalyst aqueous solution is evaporated quickly, thereby realizing the efficient concentration of the catalyst aqueous solution.

[0126] After being concentrated to a certain extent, catalyst crystals begin to precipitate from the catalyst aqueous solution. When the concentration of soluble impurities in the solution is high, the switch of the heating seat 502 is turned off to avoid excessive concentration causing impurities to be output in the form of crystals.

[0127] The electric push rod 702 is switched on. When the electric push rod 702 is working, the plug 706 is driven away from the evaporation plate 501 through the connecting frame 703, so that the solution and the catalyst crystals on the evaporation plate 501 fall onto the filter paper 705 through the output hole. Due to the evaporation process, water vapor exists in the space above the filter paper 705 in the evaporation tank 204. Therefore, the air pressure above the filter paper 705 is greater than the air pressure below the filter paper 705. At this time, under the action of the air pressure difference on both sides of the filter paper 705, the concentrated solution passes through the filter paper 705, while the catalyst crystals remain on the filter paper 705, thereby achieving the filtering work of the catalyst. In this process, the catalyst and the soluble impurities are separated;

[0128] During the operation of the heating seat 502, the steam generated when the solution is concentrated enters the annular seat 301 above through the steam pipe 303, and then enters the heat exchange tube 302. When the steam is in the heat exchange tube 302, the steam exchanges heat with the water in the dissolution tank 101 to achieve heating of the aqueous solution in the dissolution tank 101, which is convenient for the dissolution of the catalyst raw material. Since the solution is in a low-pressure state when it is concentrated, the steam temperature inside the steam pipe 303 is lower than 100 degrees Celsius. Therefore, even if the heat exchange work is carried out for a long time, the water temperature in the dissolution tank 101 can be controlled below 100 degrees Celsius, thereby avoiding boiling of the water in the dissolution tank 101 and thus avoiding waste of water resources. At the same time, it also avoids the precipitation of catalyst crystals at the bottom of the dissolution tank 101, which is convenient for the subsequent collection of catalyst crystals.

[0129] The steam in the heat exchange tube 302 is liquefied into water and enters the cylinder 401 through the annular seat 301 and the return pipe 404 below, and is stored on the piston 408;

[0130] As the catalyst purification process proceeds, the amount of pure water in the cylinder 401 increases continuously. At this time, the piston 408 is driven upward by the hydraulic push rod 402, and the water above the piston 408 enters the nozzle through the one-way valve 407 and the water supply pipe 403, and then is output at high speed through the nozzle. The high-speed water flow causes the catalyst raw materials in the net cylinder 102 to turn over, further improving the dissolution efficiency of the catalyst raw materials.

[0131] After the entire purification work is completed, the switch of the third solenoid valve 409 is turned on, and the pure water above the piston 408 enters the space below the piston 408 in the cylinder 401 through the third solenoid valve 409. At this time, the third solenoid valve 409 is closed, and the piston 408 is driven down by the hydraulic push rod 402, and the pure water below the piston 408 is pressed into the connecting seat 601 through the connecting pipe 406, and then output through the nozzle 602. The high-speed water flow rinses the catalyst crystals on the filter paper 705 to wash away the residual solution on the surface of the catalyst crystals, and the rinsing time is controlled to avoid a large amount of dissolution of the catalyst crystals;

[0132] After flushing, the concentrated liquid at the bottom of the evaporation tank 204 is output through the output pipe 210, and the inert gas is injected into the evaporation tank 204 through the tube body 208 and the L-shaped tube 209, and the switch of the heating seat 502 is turned on again. Since the evaporation tank 204 is filled with inert gas at this time, when the heating seat 502 is working, the gas can be heated by the fins 503, so that the catalyst crystals on the filter paper 705 are in a high-temperature inert gas environment, and the catalyst is dried. During the drying process, an appropriate amount of clean water is injected into the dissolving tank 101, and the steam generated by the drying is liquefied in the heat exchange tube 302, thereby ensuring the drying effect of the catalyst;

[0133] After drying, remove the sealing cover 206, disassemble the bracket 701, take the bracket 701, the electric push rod 702, the connecting frame 703, the sealing ring 704 and the filter paper 705 out of the evaporation tank 204, collect the dried catalyst on the filter paper 705, and ensure the aging efficiency of the catalyst by using the dry and pure catalyst.
