When the electric telescopic rod 304 is controlled to drive the protective cover 3051 to reach the first height, the protective cover 3051 drives the sealing ring 3503 to seal the centrifugal hole 306, and at the moment, distilled mixed liquid and mother liquid can be injected into the centrifugal roller 303 and mixed for crystallization processing. When the electric telescopic rod 304 is controlled to drive the protective cover 3051 to reach the second height, the protective cover 3051 drives the sealing ring 3053 to move to the position above the centrifugal hole 306, and mother liquor can be separated from the centrifugal hole 306 in the centrifugal rolling rotation process, so that solid-liquid separation is completed.
The upper portion of visor 3051 is equipped with observation hole 3055, is equipped with the sealing washer on the observation hole 3055, can with visor 3051 sealing connection when the observation hole 3055 is closed. Mother liquor and seed crystals can be added into the centrifugal drum 303 through the observation holes 3055, and crystallization in the centrifugal drum 303 can be observed conveniently. The fourth conveying pipe 109 is provided with an electric control valve which is used for feeding the fourth conveying pipe 109 on one hand and discharging sclareol crystals on the other hand. The fourth conveying pipe 109 is connected with the protective cover 3051 by a telescopic pipe, so that the protective cover 3051 can move up and down normally.
When the crystallization centrifugal mechanism 3 is adopted to mix and crystallize distilled liquid and mother liquor and perform solid-liquid separation, firstly, when the electric telescopic rod 304 is controlled to drive the protective cover 3051 to reach a first height, the protective cover 3051 drives the seal ring 3503 to form a seal on the centrifugal hole 306, then distilled liquid and mother liquor are injected into the centrifugal roller 303, and the small-sized driving motor 302 is started to drive the centrifugal roller 303 to rotate, so that the distilled liquid and the mother liquor are fully mixed; then adding quantitative seed crystal to make sclareol crystal in the mixed liquor complete crystallization. Then, the separation of sclareol crystals and mother liquor is started, at the moment, when the electric telescopic rod 304 is controlled to drive the protective cover 3051 to reach the second height, the protective cover 3051 drives the sealing ring 3053 to move to the position above the centrifugal hole 306, at the moment, the sealing ring does not seal the centrifugal hole 306 any more, and when the centrifugal roller 303 rotates, the mother liquor in the sclareol crystals can be thrown out through the centrifugal hole 306 under the action of centrifugal force, so that the separation of sclareol crystals and the mother liquor is realized.
In the actual separation process of sclareol crystals and mother liquor, as the mother liquor is thrown out of the centrifugal roller 303 gradually, the solid-liquid concentration inside the centrifugal roller 303 is gradually increased, more sclareol crystals are accumulated at the bottom of the centrifugal roller 303, under the filtering action of a filter screen, the accumulated sclareol crystals easily cause the blockage of the centrifugal holes 306, the separation of the mother liquor is not facilitated, and a longer time is needed to gradually complete the solid-liquid separation, so that the energy consumption is increased and the production efficiency is reduced. In order to solve the above problem and improve the effect of solid-liquid separation, when the mother liquor separation amount is reduced, the electric control valve is closed, the electric telescopic rod 304 is controlled to drive the protective cover 3051 to move up and down while ensuring that the position of downward movement is higher than the first height (namely, the sealing ring 3053 is ensured to be positioned above the centrifugal hole 306, the sealing ring 3053 does not seal the centrifugal hole 306), as the sealing ring 3503, the protective cover 3051 and the centrifugal roller 303 are in sealing connection, the extrusion and suction effects can be generated in the process that the protective cover 3051 drives the sealing ring 3503 to move up and down relative to the centrifugal roller 303, namely, when the protective cover 3051 drives the sealing ring 3503 to move down relative to the centrifugal roller 303, the air in the centrifugal roller 303 can be extruded, the residual mother liquor in the centrifugal roller 303 can be promoted to be discharged from the centrifugal hole 306 after the internal pressure of the centrifugal roller 303 is increased, and then the mother liquor in the centrifugal roller 303 is better discharged in cooperation with the centrifugal action of the centrifugal roller 303; the protective cover 3051 drives the seal ring 3503 to move upward relative to the centrifugal roller 303, so as to generate a suction effect, and when air is pumped into the centrifugal roller 303 from the centrifugal hole 306, sclareol crystals accumulated and blocked at the centrifugal hole 306 are caused to separate from the centrifugal hole 306 (at this time, the centrifugal roller 303 is controlled to stop rotating so as to prevent the centrifugal effect from affecting the separation of sclareol crystals accumulated and blocked at the centrifugal hole 306). Through the operation, the effect of separating the mother liquor from the centrifugal holes 306 can be effectively improved, and the solid-liquid separation efficiency is improved.
The drying and crushing mechanism 4 comprises a drying inner cylinder 401 communicated with a fifth conveying pipe 1092, a drying outer cylinder 409 is rotatably connected to the outside of the drying inner cylinder 401, and a drying gap is arranged between the drying inner cylinder 401 and the drying outer cylinder 409; the top of the drying outer cylinder 409 is fixedly connected with a servo motor 402, the driving end of the servo motor 402 is fixedly connected with a gear 403, the gear 403 is meshed with a gear ring 404 on the outer ring of the drying inner cylinder 401, and two ends of the drying outer cylinder 409 are fixedly connected with balance wheels 405; the servo motor 402, the gear 403 and the gear ring 404 can drive the drying inner cylinder 401 to rotate relative to the drying outer cylinder 409, so that sclareol crystals entering the drying inner cylinder 401 are effectively dried and crushed. The balance wheels 405 are fixedly connected to the two ends of the drying outer cylinder 409, and the drying inner cylinder 401 can be effectively supported through the arrangement of the balance wheels 405, so that the rotating stability of the drying inner cylinder 401 is improved.
One side of the drying outer cylinder 409 is fixedly connected with a hot air shell 406, an electric heating wire 407 is arranged in the hot air shell 406, and one side of the hot air shell 406 is fixedly connected with a blower 408. The electric heating wires 407 are arranged to heat the air conveyed by the air blower 408, and the heated air effectively dries sclareol crystals in the drying inner cylinder 401 through a drying gap between the drying inner cylinder 401 and the drying outer cylinder 409, so that sclareol crystal products are finally obtained, and later packaging is facilitated.
When sclareol crystals after solid-liquid separation are pumped into the drying and crushing mechanism 4 through the third water pump 1091 and the fifth conveying pipe 1092 in the crystallization and centrifugation mechanism 3, on one hand, sclareol crystals in the crystallization and centrifugation mechanism 3 and in the third water pump 1091 and the fifth conveying pipe 1092 are not easy to be completely pumped out, and on the other hand, the third water pump 1091 and the fifth conveying pipe 1092 are easy to be blocked due to poor flowability of sclareol crystals after solid-liquid separation. Therefore, when sclareol crystals are extracted, the sealing ring 3503 and the centrifugal roller 303 and other parts can be further matched with each other, so that the discharge of sclareol crystals after separating liquid in the centrifugal roller 303 can be promoted. Specifically, in the process of extracting sclareol crystals through the third water pump 1091 and the fifth conveying pipe 1092, when a blockage occurs or sclareol crystals in the centrifugal roller 303 cannot be completely discharged, the electric control valve is controlled to be closed, the electric telescopic rod 304 is controlled to drive the protective cover 3051 to reach a third height, the corresponding sealing ring 3503 reaches the lower part of the centrifugal hole 306, at this time, the sealing ring 3503 and the outer wall of the centrifugal roller 303 keep a sealing state, and when the electric telescopic rod 304 drives the protective cover 3051 to continuously move downwards, air in the centrifugal roller 303 is further compressed, and then generated pressure can promote the discharge of sclareol crystals in the centrifugal roller 303 or in the third water pump 1091 and the fifth conveying pipe 1092; before the electric telescopic rod 304 drives the protective cover 3051 to move upwards, the electric control valve is opened, and air can enter the centrifugal roller 303 to prepare for compressing the air in the centrifugal roller 303 next time. The protection cover 3051 is driven to reciprocate up and down below the third height position (i.e. the sealing ring 3503 is ensured to be always positioned below the centrifugal hole 306) by controlling the electric telescopic rod 304, so that the sclareol crystals in the centrifugal roller 303 or the third water pump 1091 and the fifth conveying pipe 1092 are completely discharged into the drying and crushing mechanism 4.
