[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0029] Reference Figure 1-Figure 4 The crystallization pool unloading control structure for recycling copper-containing etching waste liquid to produce copper sulfate pentahydrate includes a crystallization pool body 1 for recycling copper-containing etching waste liquid, and a discharge port 2 is provided on the crystallization pool body 1. The bottom end of the crystallization pool body 1 is inclined toward the discharge port 2, so that the material to be discharged can enter the discharge port 2 under the traction of gravity. The crystallization pool body 1 is provided with a material guide slide 3, a cylinder 4 and a crushing mechanism. The specific components are as follows:

[0030] Reference Figure 2 The guide chute 3 is fixedly connected to the bottom end of the crystallization pool body 1, and the guide chute 3 is connected to the discharge port 2. The guide chute 3 is tilted downward. By tilting the bottom end of the guide chute 3, the material can be quickly discharged under the traction of gravity when entering the guide chute 3. One end of the guide chute 3 is closed, and the other end of the guide chute 3 is open;

[0031] The cylinder 4 is fixedly installed at the bottom end of the material guide slide 3, and the output end of the cylinder 4 extends into the material guide slide 3 through a dynamic sealing structure. It should be noted that the dynamic sealing structure is a well-known technology, so it will not be described in detail. The dynamic sealing structure can prevent the cylinder 4 from affecting the sealing of the material guide slide 3 during the telescopic movement.

[0032] The crushing mechanism is arranged on the output end of the cylinder 4 and is rotatably connected to the material guide slide 3. The crushing mechanism is driven by the cylinder 4 and is used to crush the crystals produced in the crystallization pool body 1.

[0033] Reference Figure 2 With attached Figure 3 , the further implementation method is as follows: the crushing mechanism includes a threaded rod 5, a connecting rod 6, a threaded sleeve 7, a crushing blade 8, a crushing cone 9 and a telescopic dust cover 10, and the specific components are as follows:

[0035] The connecting rod 6 is rotatably mounted on the connecting portion of the material guide slideway 3 and the material outlet 2. A guide ring groove is provided on the material guide slideway 3. A guide slider fixedly connected to the connecting rod 6 is slidably sleeved in the guide ring groove. The guide ring groove is provided so that the guide slider can be guided and limited by the guide ring groove. Therefore, the guide slider can only move circumferentially in the guide ring groove, so that the connecting rod 6 fixedly connected to the guide slider can move circumferentially.

[0036] The threaded sleeve 7 is threadedly connected to the threaded rod 5, and the bottom end of the threaded sleeve 7 is fixedly connected to the connecting rod 6, and the crushing blade 8 is fixedly connected to the threaded sleeve 7. A sealing valve is provided between the discharge port 2 and the threaded sleeve 7 to prevent leakage when the crystallization pool body 1 is in operation. It should be noted that: the threaded sleeve 7 is fixedly connected to the connecting rod 6, so the threaded sleeve 7 is restricted by the connecting rod 6 and cannot move in the vertical direction. The vertical movement of the threaded rod 5 is used to drive the threaded sleeve 7 to rotate, so that the crushing blade 8 can crush the crystals in the discharge port 2 to prevent the crystals from being blocked in the discharge port 2;

[0037] Reference Figure 4 The crushing cone 9 is fixedly connected to the top of the threaded rod 5. The outer wall of the crushing cone 9 is fixedly provided with a plurality of hemispherical protrusions. The protrusions are provided so that the crushing cone 9 is in point contact with the crystal, which reduces the force-bearing area of ​​the crystal and helps to improve the crushing efficiency of the crushing cone 9. The upper end of the crushing cone 9 is a cone structure arranged upward, and the lower end of the crushing cone 9 is a cone structure arranged downward. Through the cone structure at the upper end, the crystal falling onto the crushing cone 9 can fall under the traction of gravity.

[0038] Two telescopic dust covers 10 are provided, and the two telescopic dust covers 10 are respectively fixedly arranged between the material guide slide 3 and the bottom end of the threaded sleeve 7 and between the top end of the threaded sleeve 7 and the bottom end of the crushing cone 9. The threaded rod 5 and the output end of the cylinder 4 are sleeved on the telescopic dust covers 10. The telescopic dust covers 10 are used to protect the threaded rod 5 and the output end of the cylinder 4 to avoid direct collision between the threaded rod 5 or the output end of the cylinder 4 and the crystal, thereby preventing damage to both, which helps to extend the service life of the threaded rod 5 and the cylinder 4.

[0039] The functional principle of the utility model can be explained through the following operation modes:

[0040] When the crystals need to be crushed and unloaded in the crystallization pool for producing copper sulfate pentahydrate by recycling copper-containing etching waste liquid, the cylinder 4 is started to drive the threaded rod 5 to perform vertical lifting and lowering, and the threaded rod 5 drives the crushing cone 9 to perform vertical lifting and lowering, and the crushing cone 9 squeezes and crushes the crystals at the bottom end of the crystallization pool body 1, so that the crystals can enter the discharge port 2 under the traction of gravity. In the process of vertical lifting and lowering, the threaded rod 5 drives the threaded sleeve 7 to rotate, and the threaded sleeve 7 drives the connecting rod 6 to rotate, and the connecting rod 6 drives the guide slider to perform circumferential movement in the guide ring groove, and the threaded sleeve 7 drives the crushing blade 8 to rotate, and the crushing blade 8 performs secondary crushing on the crystals, so that the crystals are discharged through the guide slide 3.
