As an embodiment of the present invention, the contact surface between the sliding chute and the impact block 25 is designed to be a horn-shaped structure; the during operation, when striking piece 25 outwards slides, because the spout structural design of loudspeaker form, make the gas in the air guide hole can be through the spout and strike the clearance blowout between the piece 25, the realization is blown the clearance to the remaining crystal granule of intrados of reaction chamber 2, and striking piece 25 is more in the inside roll-off of spout, the clearance between spout and the striking piece 25 is big, and then the blowout gas is many, the effect is more obvious, consequently when striking piece 25 when striking, can realize the biggest gas blowout volume, make the crystal granule that the striking produced can effectively be blown the clearance.
The specific working process is as follows:
in operation, when chemical raw materials need to be crystallized, the sealing cover is unscrewed, then the chemical raw materials are injected into the reaction bin 2 through the first connecting pipe 13, after the injection work is completed, the sealing cover is screwed down again to enable the reaction bin 2 to be effectively sealed, the power is switched on, heating plates 23 uniformly arranged on the outer arc surface of the reaction bin 2 start to heat, then the chemical raw materials in the reaction bin 2 are heated, then the motor 11 is switched on, an output shaft of the motor 11 drives the stirring shaft 3 to rotate, the stirring shaft 3 further drives the stirring frame 21 to rotate, the chemical raw materials are fully mixed, the stirring frame 21 can further drive the scraping brush 22 on the surface of the stirring frame to scrape crystals on the inner surface of the kettle body 1, finally the chemical raw materials are saturated solution, then the power of the heating plates 23 is switched off, the first control valve 12 is switched on, cooling liquid is injected into the first cavity through the liquid injection hole, after the injection of the cooling liquid is completed in the first cavity, the first control valve 12 is closed, the water pump 16 is opened, the water pump 16 continuously pumps the cooling liquid in the first cavity into the cooling bin 17 through the guide hole, and finally the cooled cooling liquid is guided back into the first cavity through the guide pipe, and the cooling liquid is continuously cooled through the cooling bin 17, so that the cooling liquid can continuously keep a lower temperature state, thereby effectively and fully cooling the saturated solution of the chemical raw materials in the reaction bin 2, the cooled saturated solution can be in a supersaturated state, crystals can be precipitated and adsorbed on the inner surface of the reaction bin 2, at the moment, the scraping brush 22 of the stirring shaft 3 continuously scrapes the crystals on the inner surface of the reaction bin 2, the excessive crystals are prevented from influencing heat conduction, and therefore, a rapid crystallization effect can be realized, but the solution in the second cavity close to the axial position of the reaction bin 2 cannot directly contact with the side wall of the reaction bin 2, therefore, the crystallization effect is slow, and the reflux channels are jointly formed in the stirring shaft 3 and the stirring frame 21 and communicated with the guide pipe, so that the cooling liquid with a lower temperature can flow in the reflux channels, on one hand, the saturated solution can be cooled more quickly, on the other hand, the saturated solution can be crystallized on the surface of the stirring frame 21, and the crystallization efficiency of the saturated solution is accelerated; after the saturated solution is fully crystallized, the second control valve 15 is opened, the redundant saturated solution is discharged and collected through the discharge hole, then the blower is opened, air is introduced into the air passage through the air inlet, then the air can be sprayed out through the air outlets 24 uniformly distributed on the surface of the stirring frame 21, and the stirring shaft 3 is in a rotating state, so that the scraping brush 22 can continuously clean the inner surface of the reaction bin 2, the air sprayed out from the air outlets 24 can reduce the attachment of crystals on the surface of the stirring frame 21, on the other hand, the residual crystals on the inner surface of the reaction bin 2 can be effectively blown, and the crystallization cleaning effect is effectively improved; when the stirring shaft 3 drives the stirring frame 21 to perform stirring operation, because the temperature of the stirring frame 21 is lower than the temperature of the saturated solution, the saturated solution is easy to crystallize on the surface of the stirring frame 21, so that more crystals are adhered on the surface of the stirring frame 21, especially, after the cooling liquid is introduced into the inside of the backflow channel, the crystallization phenomenon on the surface of the stirring frame 21 is greatly aggravated, so that a large amount of crystals are adhered on the surface of the stirring frame 21, the stirring resistance and the weight of the stirring frame 21 are increased, further, the load of the motor 11 is increased, and after the crystallization operation of the saturated solution is completed, more crystals are remained on the surface of the stirring frame 21 and are difficult to remove, so that the stirring frame 21 can be directly diluted and re-crystallized with new chemical raw materials, and the recrystallization operation is dissolved, a large amount of manpower, material resources and energy costs can be consumed in the circulation, and therefore, by, when the stirring shaft 3 is started or changed in speed, the first impact plate 32 is driven to rotate firstly, then the first impact plate 32 impacts the second impact plate 33, and the second impact plate 33 drives the vibration ring 31 to rotate rapidly and instantly in an accelerated manner, so that the vibration of the stirring frame 21 is realized; when the first impact plate 32 collides with the second impact plate 33 and the pressure of the first spring 34 acts, the gas in the air bag 35 is compressed and then enters the air guide hole through the pipeline, so that the air pressure in the air guide hole is increased, the impact block 25 can slide outwards in the sliding groove, the impact on the inner surface of the reaction bin 2 is realized, the adhesion of relatively stubborn crystals on the inner surface of the reaction bin 2 is avoided, and the breaking and dismantling function can be realized; when the impact block 25 slides outwards, due to the horn-shaped sliding groove structure design, the gas in the gas guide hole can be sprayed out through the gap between the sliding groove and the impact block 25, and the blowing cleaning of the crystal particles remained on the inner arc surface of the reaction bin 2 is realized.
