The inner walls of the annular mounting notches corresponding to the crystal breaker 12 and the disc spring set 13 are smooth wall surfaces, in an initial state, the crystal breaker 12 is fixed in the annular mounting notches under the matching of the disc spring set 13 and the second positioning ring 14, the disc spring set 13 slightly deforms, and the thrust force applied to the crystal breaker 12 by the disc spring set 13 is slightly larger than the thrust force of liquid in the lifting sleeve 7a on the crystal breaker 12; when the lifting sleeve 7a rises under the action of external force to break the copper sulfate crystals, the larger copper sulfate crystals knocked down by the dredging and crushing teeth 7c fall into the lifting sleeve 7a and impact the crystal crusher 12, so that the disc spring group 13 is further deformed to enable the crystal crusher 12 to move downwards, then the crystal crusher 12 rapidly moves upwards under the action of the rebound force of the disc spring group 13, and large copper sulfate crystals which are not crushed are impacted until the large copper sulfate crystals are crushed to a preset size. Meanwhile, the action of the disc spring can be matched with the up-and-down action of the lifting sleeve during crystal breaking, so that the crystal breaker is in repeated up-and-down oscillation, the large crystals in the lifting sleeve can be effectively broken, and the crystals are prevented from being deposited in the lifting sleeve.
In this embodiment, the crystal crusher 12 includes a mounting ring 12a and three mounting rods 12b, which are uniformly distributed in the inner hole of the mounting ring 12a and have free ends connected with each other, and have vertical cross sections in the shape of an isosceles acute triangle, a first mitsubishi broken crystal cone 12c is axially welded on each mounting rod 12b along the lifting sleeve 7a, and a second mitsubishi broken crystal cone 12d is axially welded on the contact portion of each mounting rod 12b at the center of the inner hole of the mounting ring 12a along the lifting sleeve 7 a; the included angles formed by the generatrix and the bottom of the first Mitsubishi crystal-breaking cone 12c and the second Mitsubishi crystal-breaking cone 12d are 84-86 degrees. The isosceles acute angle triangle design of installation pole, the tip is the direction that comes towards the liquid equally, has supplementary broken brilliant effect. Meanwhile, a sharp rhombus broken crystal cone is designed, so that crystals are prevented from being attached to the broken crystal cone, and meanwhile, large crystals falling from the broken crystal cone are easy to pierce. Through experiments, the surface of the Mitsubishi crystal cone with the shape is still smooth after continuous operation for half a year. Another reason for this excellent effect is that the mitsubishi boule is constantly being washed away by the liquid. Unlike the side wall of the liquid outlet at the bottom of the tank, the flow velocity at the side wall is slow, and no liquid is washed away, so the crystallization is easy.
The device of the invention is used for preventing the blockage of the discharge port, and is started or started periodically when the liquid using equipment detects that the liquid amount is obviously reduced. As the case may be.
The working principle of the invention is as follows: when the discharge port 1a is blocked by crystallization to cause over-small flow, the material shoveling device 7 starts to work; start high-pressure pump 5, open first solenoid valve 4b, second solenoid valve 8b is in the closed condition, high-pressure pump 5 goes into annular inflation portion 3a with outside sulphuric acid solution through 4 pump income high pressure feed liquor pipes, the high-pressure sulphuric acid solution that gets into annular inflation portion 3a promotes first retainer ring 7d and rises, first retainer ring 7d rises and drives lift cover 7a and rise towards the discharge gate orientation fast, the mediation crushing tooth 7c on lift cover 7a top can be effectively strike off the crystal material that is stained with on 1a inside wall of discharge gate, can carry out coarse crushing to the crystal material of jam in discharge gate 1a department simultaneously.
The first solenoid valve and the second solenoid valve are in a mutual opening mode, and the mutual interval time can be determined according to the value of the pressure sensor, and can also be calculated according to the capacity of the high-pressure cavity, which is common knowledge in the field and is not described herein again. First solenoid valve and second solenoid valve interactive operation make the lift cover form up-and-down reciprocating motion, and its purpose is in order to solve when the crystallization is thick, and the crystallization can't be got rid of completely in the lift cover once assaulting.
When the lifting sleeve 7a rises to the top of the first positioning ring 7d to be matched with the bottom of the limiting ring 3c, the liquid spraying hole 7b conducts the lifting sleeve 7a, the high-pressure cavity 3d and the high-pressure liquid inlet pipe 4, and the top end of the lifting sleeve 7a extends into the storage tank 1 through the discharge hole 1 a; at the moment, the high-pressure sulfuric acid in the high-pressure cavity 3d is discharged through the liquid spraying hole 7b, enters the lifting sleeve 7a, rises into the discharge hole 1a, and assists dredging of the crystalline material blocked at the discharge hole 1a by means of the recoil action.
And after dredging is finished, finishing the interactive opening mode of the first electromagnetic valve and the second electromagnetic valve, and simultaneously opening the outlet valve 1b and the discharge valve 2 a. The resetting mechanism 8 is started to reset the lifting sleeve 7a, the first electromagnetic valve 4b is closed, the second electromagnetic valve 8b is opened, high-pressure sulfuric acid solution generated by the high-pressure pump 5 enters the resetting cavity 3e through the resetting liquid inlet pipe 8a, the high-pressure sulfuric acid solution entering the resetting cavity 3e pushes the first positioning ring 7d to descend through the liquid return hole 8d, the first positioning ring 7d descends to drive the lifting sleeve 7a to descend to the annular protection pad 7e at the bottom end of the first positioning ring 7d to be contacted with the top end of the guide sealing sleeve 6, and liquid in the resetting cavity 3e is discharged from the second liquid discharge hole 8e so that the lifting sleeve 7a can be subjected to next dredging process. The end of dredging is judged by the pressure value of the pressure sensor and the time for keeping constant pressure. Or the number of times of the mutual starting of the first electromagnetic valve and the second electromagnetic valve. As the case may be. This is also common knowledge of the person skilled in the art.
When the discharge valve is also opened, if large crystals still exist in the lifting sleeve, the crystals are crushed by the crystal crusher.
The above-mentioned embodiments are only for convenience of description, and are not intended to limit the present invention in any way, and those skilled in the art will understand that the technical features of the present invention can be modified or changed by other equivalent embodiments without departing from the scope of the present invention.
