In combination with the above preferred embodiments, the working principle of the present invention is as follows:
Firstly, operators need to select floating blocks 606 with different densities according to different selected organic peroxides, then plug a collecting drum 513 into a connecting pipe I504 through a separating drum 502, and enable a chute on the collecting drum 513 to be in sliding connection with a limiting block 509 in the connecting pipe I504, at the moment, the collecting drum 513 continues to move downwards in the placing process of the operators, the collecting drum 513 can drive a bottom end of a mounting shaft 510 to be plugged into a rubber sleeve in the supporting plate 508 through the supporting plate 508, after the supporting plate 508 is attached to a transverse plate 507, the collecting drum 513 and the mounting shaft 510 are mounted at specified positions, then the operators move the connecting cover 301 to the top end of a supporting seat 1 through a connecting ring 302, two clamping blocks 304 on the supporting seat 1 penetrate into the connecting ring 302, and the rotating mounting of the connecting cover 301 on the top end of the supporting seat 1 is realized through the rotating connection between the connecting cover 301 and the connecting ring 302, so that the whole mounting combination of the separating device is completed, and the reaction liquid is separated and extracted conveniently;
the specific using steps are as follows:
Wherein, gas-liquid separation:
An operator fills organic peroxide reaction liquid into the feeding tank body 501, then the reaction liquid enters the spiral tank body along the transverse tank body of the feeding tank body 501, then the spiral tank body performs circular motion along the inner wall of the separation cylinder 502, the reaction liquid is thrown on the wall of the separation cylinder 502 due to the fact that the reaction liquid is heavier and is subjected to larger centrifugal force, finally gas is separated from the reaction liquid, the gas rotation speed is gradually reduced, finally moves upwards and flows out from the top, and the reaction liquid flows out from the bottom, so that volatile components and impurities in the reaction liquid are removed, further purification or recovery of the gas can be performed, subsequent reaction or purification of the reaction liquid can be performed, and the purity of a product is improved;
Meanwhile, in the process of flowing the reaction liquid in the feeding tank body 501, the reaction liquid pushes an impeller 708 which is rotatably arranged between the feeding tank body 501 and a fixed sleeve 706 through a connecting shaft 707, so that the impeller 708 rotates and drives one of driving wheels 709 through the connecting shaft 707, and as a driving belt 704 is in transmission connection between the two driving wheels 709, synchronous rotation of the two driving wheels 709 can be realized through the driving belt 704, and the driving wheels 709 synchronously drive a rubber roller 703 and a gear 705 to rotate through a transmission shaft 702;
during the process of the gas rising, the gas is guided by the conical guide sleeve 305 to collide on the mounting plate 307, then the gas moves along the mounting plate 307 towards the periphery and passes through the condensation plate 308, condensation of the reaction liquid in the reaction liquid is realized under the action of the condensation plate 308, in the process of the condensation of the reaction liquid, as the rubber roller 703 is in direct contact with the connecting cover 301, the rotating of the rubber roller 703 drives the connecting cover 301 to rotate at the top end of the connecting ring 302 through friction force between the rubber roller 703 and the connecting cover, the rotating connecting cover 301 drives the symmetrical two cleaning blocks 309 to rotate, so as to realize scraping of the condensation reaction liquid on the lower surface of the condensation plate 308, the scraped condensate falls on the conical guide sleeve 305, then the condensate enters into the separation cylinder 502 from the through hole along the inclined surface of the conical guide sleeve 305, the liquefied reaction liquid directly moves downwards along the inner wall of the separation cylinder 502, so that the influence on internal separation is reduced, the falling of the reaction liquid drops is prevented from influencing the rising of the gas and the downward spiral separation of the liquid in the device, and finally the condensate is subjected to gas separation in the gas separation step again, the gas separation step is guaranteed, the quality is reduced, the potential waste of the reaction liquid is reduced, and the waste of the reaction liquid in the gas separation step is reduced, and the waste of the waste is reduced, and the waste of the reaction liquid is reduced, and the waste is reduced;
Wherein, solid-liquid separation:
The reaction liquid after gas-liquid separation falls into a collecting drum 513 in a connecting pipe I504 along a conical drum at the bottom of a separating drum 502, and is subjected to solid-liquid separation through a filter screen 505 arranged at the bottom of the collecting drum 513, in the separation process, a gear 705 drives an outer gear ring 503 in meshed connection with the gear 705 to rotate, a rotating outer gear ring 503 drives a cleaning frame 512 to rotate, the rotation of the cleaning frame 512 can not only clean the inner wall of a water discharge space formed among a conical blanking sleeve 603, the connecting pipe I504, the separating drum 502 and a supporting seat 1, but also drive a sealing ring 506 to rotate, the rotating sealing ring 506 can drive a mounting shaft 510 inserted into the inner side of the sealing ring through a rubber sleeve to synchronously rotate, the rotation of the mounting shaft 510 drives two stirring blocks 511 to synchronously rotate, and the rotation of the stirring blocks 511 realizes the solid impurities in the collecting drum 513 and the reaction liquid, so as to avoid the mesh of the solid impurities blocking the filter screen 505 from affecting the separation quality, thereby guaranteeing the high-efficiency stability of the solid-liquid separation of the reaction liquid, reducing the abrasion and blockage of equipment, prolonging the service life of the equipment, and improving the fluidity of the reaction liquid so as to facilitate the subsequent continuous separation operation, and meet the requirement of higher purity of products;
Wherein, the saturated solution of the reaction liquid is separated from water:
When the reaction liquid is subjected to solid-liquid separation and falls into the inner side of the bottom of the supporting seat 1 along the second connecting pipe 604, as the density of the reaction liquid saturated solution of the reaction liquid is higher than that of water, water floats at the top end of the reaction liquid saturated solution, when the reaction liquid continuously falls into the bottom of the supporting seat 1, water gradually overflows the top end of the conical blanking sleeve 603, and then is discharged from the first discharging pipe 601 through the guide of the conical blanking sleeve 603, when the reaction liquid saturated solution in the bottom of the supporting seat 1 is excessive, a floating block 606 with the density between the reaction liquid saturated solution and the water moves upwards under the pushing of the buoyancy of the reaction liquid saturated solution, so that the gap between the conical blanking sleeve 603 and the second connecting pipe 604 is blocked, the reaction liquid saturated solution is prevented from being discharged from the first discharging pipe 601 through the conical blanking sleeve 603, finally, the discharging of the reaction liquid saturated solution in the bottom of the supporting seat 1 can be realized through opening the second discharging pipe 602, so that the reaction liquid saturated solution and water are conveniently treated, the influence on the environment is reduced, in addition, the reaction liquid saturated solution and the water are not separated, the impurity in the reaction liquid saturated solution can be removed, the purity of the product can be further conveniently collected, and the product can be further treated.
