DETAILED DESCRIPTION
[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Specific embodiment 1
[0031] See also Figure 1 , 2 4. The utility model is a purification device for wet zinc smelting leachate, comprising a main purification tank 1 and an auxiliary purification tank 2 arranged directly behind the main purification tank 1, partitions 103 are evenly spaced in the horizontal direction inside the main purification tank 1 and the auxiliary purification tank 2, a traveling vehicle 107 is arranged on one side directly above the main purification tank 1 and the auxiliary purification tank 2, and through pipes 104 are evenly spaced from top to bottom inside the partition 103.
[0032] Specifically, a liquid inlet pipe 101 is provided on the outer wall of one side of the main purification tank 1 and the auxiliary purification tank 2, and the liquid inlet pipe 101 is obliquely arranged on the outer wall of the main purification tank 1 and the auxiliary purification tank 2, and a liquid outlet pipe 102 is provided at the bottom of the other outer wall of the main purification tank 1 and the auxiliary purification tank 2. Tracks 105 are installed at the front and rear ends of the top of the main purification tank 1 and the auxiliary purification tank 2. Wheels 1071 are provided on both sides of the front and rear ends of the traveling vehicle 107, and the wheels 1071 are clamped on the outside of the track 105.
[0033] Furthermore, the main purification tank 1 and the auxiliary purification tank 2 have the same size, structure, etc. The main purification tank 1 and the auxiliary purification tank 2 are both purification units. After the leachate is purified, it needs to be introduced into multiple subsequent purification units, cyclones, etc. This is a prior art, so it will not be described in detail here. The liquid inlet pipe 101 is inclined to avoid causing large shocks to the internal solution during the addition of the leachate, shortening the time of static sedimentation. There are multiple through pipes 104 arranged according to the height, and a valve control switch is provided. The wheel 1071 can move the walking vehicle 107 on the track 105.
[0034] The operation process of this embodiment is as follows: first, the leachate and related reaction solution etc. generated in the process of hydrometallurgy are added into the main purification tank 1 through the liquid inlet pipe 101. Since a plurality of partitions 103 are arranged inside the main purification tank 1, the internal space thereof is divided into a plurality of parts, and through pipes 104 are arranged at different heights of the partitions 103. After the leachate is allowed to stand for reaction and precipitation, through pipes 104 of different heights can be opened for the upper clear liquid according to the liquid level in each space, and the through pipes 104 of different heights can discharge the upper clear liquid into the next space or the next purification unit, thereby improving the purification efficiency of the leachate. Meanwhile, when cleaning the sediment inside the main purification tank 1, the solution inside the main purification tank 1 can be pumped into the auxiliary purification tank 2 for purification operation, thereby shortening the interruption time during equipment maintenance and cleaning, and further improving the efficiency of the entire purification operation of the leachate. Specific embodiment 2
[0035] See also Figures 2 to 5 On the basis of the specific embodiment 1, what is different from the first embodiment is that: a stacking filter frame 106 and a hanging assembly 3 are provided, the hanging assembly 3 includes an inner fixing plate 301 and a motor 303 installed on the inner wall thereof, and the output shaft of the motor 303 is connected to the rotating shaft 3031 through a coupling, which solves the problem that the sediment generated inside the purification device for hydrometallurgical zinc leaching liquid during the purification process will accumulate at the bottom of each purification barrel, and long-term use will seriously affect the subsequent purification, reaction, etc., and manual cleaning will increase the workload, be time-consuming and labor-intensive, and have low work efficiency.
[0036] Specifically, the four corners of the upper surface of the stacking filter frame 106 are fixedly connected with hanging rings 1061, the inner bottom end of the stacking filter frame 106 is provided with a sponge layer 1062, and the upper surface of the sponge layer 1062 is provided with a filter cloth 1063, the other end of the rotating shaft 3031 passes through the bearing on the rear end face of the inner fixed plate 301 and is connected with the bearing on the inner wall of the outer fixed plate 302, the bottoms of the inner fixed plate 301 and the outer fixed plate 302 are fixed on the upper surface of the traveling vehicle 107, the front and rear ends of the outer wall of the rotating shaft 3031 are respectively provided with an inner rope winding roller 304 and an outer rope winding roller 305, the outer sides of the outer walls of the inner rope winding roller 304 and the outer rope winding roller 305 are wound with a steel rope 306, the other end of the steel rope 306 passes around the pulley 307 and is connected to the top of the hook 308, and the pulley 307 is installed on the upper surface of the traveling vehicle 107.
[0037] Furthermore, the sponge layer 1062 and the filter cloth 1063 can prevent the sediment from leaking out through the stacking filter frame 106, thereby filtering water and isolating the sediment. The motor 303 drives the rotating shaft 3031 to rotate under the action of the coupling, and makes the inner rope roller 304 and the outer rope roller 305 on its outer wall rotate, thereby achieving the effect of winding and releasing the steel rope 306 on the outer walls of the two.
[0038] The operation process of this embodiment is as follows: after the main purification pool 1 has been used for a period of time, the solution inside it is pumped into the auxiliary purification pool 2, wherein the sediment inside is accumulated inside the accumulation filter frame 106, and then the position of the traveling vehicle 107 is adjusted under the action of the wheels 1071 and the track 105, and then the motors 303 in the two groups of hanging components 3 on the front and rear of the traveling vehicle 107 are started, and the output shaft of the motor 303 rotates to drive the rotating shaft 3031 to rotate under the action of the coupling, and the inner rope roller 304 and the outer rope roller 305 inside and outside the outer wall of the rotating shaft 3031 rotate, and when the inner rope roller 304 and the outer rope roller 305 rotate, the steel rope wound on the outer walls of the two can be moved. The rope 306 is released along the pulley 307, and then the hook 308 is hung on the ring 1061, and then the motor 303 is reversed, so that the inner rope roller 304 and the outer rope roller 305 are reversed under the action of the rotating shaft 3031, and the steel rope 306 is rewound around the outer walls of the two, and under the action of the hook 308 and the ring 1061, the accumulation filter frame 106 can be pulled out of the main purification tank 1, and then the sediment in the accumulation filter frame 106 can be cleaned, thereby greatly improving the efficiency of treating the sediment generated during the purification process, reducing the workload of the staff, saving time and effort, and having high work efficiency. At the same time, it can prevent excessive sediment from affecting subsequent purification, reaction, etc.
