Specific embodiments
[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0024] Please refer to Figures 1-5, the present utility model provides a technical solution: including a crystallization bin 1, a water inlet pipe 113 is connected and arranged on one side of the crystallization bin 1, and high-salt wastewater can be directly discharged into the crystallization bin 1 through the water inlet pipe 113. A treatment bin 2 is connected and arranged at the top of the crystallization bin 1. The internal diameter of the treatment bin 2 is larger than that of the crystallization bin 1, which is convenient for installing components in the treatment bin 2. A winding mechanism 3 is connected and arranged at the top of the treatment bin 2. Since the winding mechanism is a common existing device (such as a winding machine), it is not described in detail in the specification. A driving member 4 is connected and arranged on one side of the winding mechanism 3, which can drive the winding and unwinding of the winding mechanism 3. A sling 5 is wound around the middle end of the winding mechanism 3. One end of the sling 5 extends into the treatment bin 2 and is connected and arranged with a connecting plate 6. A buffer unit 7 is connected and arranged at the bottom end of the connecting plate 6. A crystallization unit 9 is connected and arranged at the bottom end of the buffer unit 7. An ultrasonic generator 8 is connected and arranged at the top end of the crystallization unit 9, which can transmit sound waves to the crystallization unit 9 faster. A blanking section 13 is connected and arranged at the bottom end of the crystallization bin 1. A plurality of reinforcing ribs are connected and arranged at the bottom end of the blanking section 13. Support legs 10 are connected and arranged on the surface of the blanking section 13, which cooperate with the reinforcing ribs to increase the stability of the device. A discharge port 14 is connected and arranged at the bottom end of the blanking section 13. A valve is connected and arranged at the bottom end of the discharge port 14. Since it is a common operation and a necessary means in real life, it is not described in detail in the specification. A triangular bracket 11 is connected and arranged on one side of the inner wall of the crystallization bin 1. A refrigeration device 12 is connected and arranged at the top end of the triangular bracket 11. An air box 15 is connected and arranged on one side of the treatment bin 2. An exhaust gas inlet pipe 112 is connected and arranged at the bottom end of the air box 15. The exhaust end of other heat-generating mechanisms or devices of the equipment can be connected to the exhaust gas inlet pipe 112 for preheating utilization. An intake fan 16 is connected and arranged on one side of the air box 15. An electric heating wire 17 is connected and arranged between the two sides of the inner wall of the air box 15;
[0025] A strip-shaped hole is opened at the top end of the treatment bin 2. The bottom end of the sling 5 penetrates through the strip-shaped hole and is connected and arranged with the connecting plate 6, which can meet the displacement of the sling 5 when it is wound around the winding mechanism 3 during winding and avoid friction with the treatment bin 2.
[0026] An arc-shaped groove is opened on the outer circle of the connecting plate 6. An arc-shaped guide rail 111 is connected and arranged on one side of the inner wall of the treatment bin 2. The connecting plate 6 is slidably connected with the arc-shaped guide rail 111 through the arc-shaped groove, so as to ensure the stability of the connecting plate 6 when moving up and down.
[0027] The buffer unit 7 includes a first connecting member 71 and a second connecting member 72. The first connecting member 71 is connected to the crystallization unit 9, and the second connecting member 72 is connected to the connecting plate 6. At the top end of the first connecting member 71, an outer cylinder member 73 is connected. At the top end of the outer cylinder member 73, a transverse plate 74 is connected. On both sides of the outer cylinder member 73, sliding holes 75 are provided. The bottom end of the second connecting member 72 extends into the outer cylinder member 73, and on both sides, connecting bolts are connected. The mutually remote ends of the connecting bolts penetrate through the corresponding sliding holes 75 and are connected with a bottom lining ring 76. One end of the outer cylinder member 73 is sleeved and connected with a spring 77. The top end of the spring 77 is connected to the transverse plate 74, and the bottom end is connected to the bottom lining ring 76.
[0028] The crystallization unit 9 includes a sealing plate 91. When the crystallization unit 9 descends into the crystallization bin 1, the sealing plate 91 can seal the inner diameter of the crystallization bin 1, so as to achieve the sealing effect and ensure the internal temperature control effect. At the bottom end of the sealing plate 91, a plurality of crystallization plates 92 are connected. As Figure 5 shown, after the plurality of crystallization plates 92 enter the crystallization bin 1, they will form a curved path, so as to ensure that the wastewater can pass through fully between the crystallization plates 92 and ensure the crystallization effect. At the bottom end of the crystallization plate 92, a groove 93 is provided corresponding to the refrigeration device 12. The refrigeration device 12 can be any refrigeration device in the common technology. The shape of the groove 93 only needs to be communicated with the outer shape of the refrigeration device 12, so as not to affect the effect of cooling the wastewater during operation.
[0029] Working principle: When the utility model is in use, the driving member 4 controls the winding mechanism 3 to rotate, and the suspension cable 5 is released, so that the crystallization unit 9 is lowered into the crystallization bin 1 through the connecting plate 6. After descending to an appropriate height, the sealing plate 91 will seal the inner diameter of the top end of the crystallization bin 1. Then, high-salt wastewater is injected into the crystallization bin 1 through the water inlet pipe 113. After the injection is completed, the refrigeration device 12 is started for wastewater treatment to precipitate the salts inside. As the temperature drops, the salts will adhere to the surface of the crystallization plates 92. After the treatment is completed, the winding mechanism 3 rotates in reverse to retract the suspension cable 5, so that the crystallization unit 9 is lifted and moved into the treatment bin 2 by using the connecting plate 6. At this time, a large amount of salt crystals will adhere to the surface of the crystallization plates 92. Then, the remaining wastewater is discharged through the discharge port 14. The air intake fan 16 and the heating wire 17 are started to dry the salt crystals on the surface of the crystallization plates 92. At the same time, the hot air will also flow into the crystallization bin 1 to dry the inside of the crystallization bin 1. After the drying is completed, the ultrasonic generator 8 is started to vibrate the salt crystals adhered to the surface of the crystallization plates 92 into the crystallization bin 1 and then discharged through the discharge port 14, and the treatment is completed. If the salt crystals on the surface of the crystallization plates 92 cannot be vibrated clean, there is no need to clean them, which will play a role in inducing crystallization in the next treatment and further improving the crystallization efficiency.
