When the equipment is needed to prepare the annular resin, an operator firstly opens a feed port of the reaction kettle 2 and adds epichlorohydrin and sodium hydroxide solution into the reaction kettle 2, the liquid level of the epichlorohydrin and sodium hydroxide solution in the reaction kettle 2 is slightly lower than that of the material containing shell 5, the epoxy chloropropane and sodium hydroxide solution are replaced by the solution, then the operator adds bisphenol A into the upper side of the material containing shell 5, the added bisphenol A enters the material containing cavity 502 through the material guiding cavity 501, the inclined annular surface on the upper side of the material containing shell 5 is used for assisting the bisphenol A to enter the material guiding cavity 501, and as the bisphenol A is white crystal and has a density larger than that of the solution, if the bisphenol A is directly added into the reaction kettle 2, the bisphenol A is positioned in the inner bottom of the reaction kettle 2 to affect the dissolution rate of the bisphenol A, so that the bisphenol A needs to be added into the material containing cavity 502 first, and the bisphenol A cannot be discharged from the material containing cavity 502, and at the moment, the bisphenol A is not immersed into the solution.
After bisphenol a is added into the material containing cavity 502, an operator presses the connecting sleeve 14 downwards, the connecting sleeve 14 drives parts on the connecting sleeve to move downwards, due to the unidirectional transmission characteristic of the unidirectional gear 21, even if the unidirectional gear 21 moves downwards to keep a meshed state with the rack 22, the unidirectional gear 21 does not drive the second rotating rod 19 to rotate, the second rotating rod 19 cannot drive the ball 15 to rotate through the second gear 20, the first gear 18 and the first rotating rod 17, the through hole of the ball 15 is kept in a vertical state, the middle part of the connecting sleeve 14 is not blocked by the ball 15, during the downward movement of the connecting sleeve 14, the connecting sleeve 14 drives the air duct 13 to move downwards, the air duct 13 drives the sealing disc 11 to move downwards, the pressure between the sealing disc 11 and the pushing disc 8 is increased, and air between the sealing disc 11 and the pushing disc 8 is discharged into the external environment through the air duct 13 and the connecting sleeve 14, the sealing disc 11 moves downwards to enable the first tension spring 12 to be stretched, in the process that the air duct 13 moves downwards, the air duct 13 drives the material containing shell 5 to synchronously move downwards, when the height of the material containing cavity 502 of the material containing shell 5 is lower than the liquid level in the reaction kettle 2, solution enters the material containing cavity 502 through the through hole of the material containing shell 5 to be in contact with bisphenol A, the bisphenol A starts to be dissolved, when the material containing cavity 502 is positioned at the inner bottom of the reaction kettle 2, an operator does not press the connecting sleeve 14 downwards any more, at this time, the operator rotates the driving part 16 clockwise (the more the amount of bisphenol A is, the larger the rotating angle of the driving part 16 is) according to the added bisphenol A, the process is described later), taking the clockwise rotation of the driving part 16 by 30 DEG as an example, the driving part 16 drives the sphere 15 to rotate, the sphere 15 seals the middle part of the connecting sleeve 14, then, the operator no longer contacts with the connecting sleeve 14, at this time, because the connecting sleeve 14 is plugged, the first tension spring 12 can not reset to drive the sealing disc 11 to move upwards so that external gas enters the fixed sleeve 4 through the connecting sleeve 14 and the air duct 13, and the position adjustment of the material containing shell 5 is completed.
After the position adjustment of the material containing shell 5 is completed, an operator starts the first electric push rod 6, the telescopic end of the first electric push rod 6 drives the push disc 8 to move upwards through the connecting rod 7, the push disc 8 drives the sealing disc 11 to move upwards through gas on the push disc 8, the first tension spring 12 gradually resets, the sealing disc 11 drives the connecting sleeve 14 and parts on the connecting sleeve 14 to move upwards through the gas guide tube 13, the gas guide tube 13 drives the material containing shell 5 to move upwards, the material containing shell 5 drives bisphenol A in the material containing shell 5 to move upwards, when the bisphenol A in the material containing shell 5 is positioned above a solution, the first tension spring 12 resets, the operator controls the telescopic end of the first electric push rod 6 to move downwards, meanwhile, the material containing shell 5 and the bisphenol A in the material containing shell 5 are firstly placed in the material containing shell 5, the bisphenol A is prevented from settling to reduce the dissolving speed, and the bisphenol A is prevented from moving up and down continuously.
In the process of longitudinally reciprocating the pushing disc 8, the pushing disc 8 moves upwards to reduce the pressure below the pushing disc, the one-way valve in the exhaust hole 401 is closed, the one-way valve in the connecting pipe 10 is opened, gas at the upper side in the reaction kettle 2 enters the lower side of the pushing disc 8 in the fixed sleeve 4 through the connecting pipe 10, when the pushing disc 8 moves downwards, the pressure below the pushing disc 8 is increased, the one-way valve in the connecting pipe 10 is closed, the one-way valve in the exhaust hole 401 is opened, gas below the pushing disc 8 enters the reaction kettle 2 through the exhaust hole 401, the discharged gas is used for disturbing the solution in the reaction kettle 2, and the reaction speed of the solution in the reaction kettle 2 and bisphenol A is accelerated.
