Technical Field

[0001] The utility model relates to the field of waste material recycling, in particular to a device for recycling fixed zinc-containing waste materials. Background Art

[0002] A large amount of secondary zinc oxide waste slag will be produced during the lead and zinc smelting process. Secondary zinc oxide accounts for a considerable proportion of the waste slag. In addition, lead accounts for the largest proportion, about 10-20%. If the zinc slag is discarded directly, it will not only cause a great waste of resources, but also pollute the environment.

[0003] Chinese patent CN114682134A discloses a purification device for recycling zinc-containing industrial waste, which can realize the recycling of zinc-containing industrial waste. However, since it takes a certain amount of time for the disodium ethylenediaminetetraacetic acid solution to react with zinc slag, the zinc-containing industrial waste needs to be fed at intervals to give the disodium ethylenediaminetetraacetic acid solution and zinc slag enough time to react fully, which results in a large waste of equipment time and a low recycling efficiency.

[0020] like Figures 1 to 3 As shown, a zinc-containing fixed waste recovery device includes a discharge channel 1, a plurality of filter frames 223 are provided at the bottom of the discharge channel, a mixing mechanism 2 is provided at the bottom of the filter frame, a crushing mechanism 4 is provided at the left end of the discharge channel, and a feed port 5 is provided at the top of the crushing mechanism.

[0021] Furthermore, a plurality of long material discharge holes 224 are provided on the filter frame.

[0022] In at least one embodiment, the crushing mechanism includes a crushing box, a hammer crushing head 41 is arranged inside the crushing box, and a driving motor is arranged outside the crushing box, and the driving motor is connected to the hammer crushing head.

[0023] In at least one embodiment, the mixing mechanism includes an outer shell 22, the top of the outer shell is fixedly connected to the bottom of the discharge channel, the bottom of the outer shell is provided with a bottom plate 21, the bottom of the bottom plate is provided with a rotating motor 25, the output shaft of the rotating motor passes through the bottom plate and is connected to a stirring shaft 28, the outer shell is provided with a liquid inlet 23 and a liquid outlet 24, wherein the liquid inlet can be used to inject disodium ethylenediaminetetraacetic acid solution, and the liquid outlet can be used to discharge waste liquid, and a discharge port is provided on one side of the outer shell, and the discharge port can be used to collect zinc hydroxide precipitate.

[0024] Furthermore, a fixed plate 26 is provided on the bottom plate, and a plurality of air blowing pipes 27 are provided on the fixed plate. The air blowing pipes can blow air into the mixing mechanism to accelerate the reaction between the zinc slag and the solution.

[0025] Furthermore, a socket 221 is provided on the side wall of the outer shell, and a sealing plate 225 is inserted into the socket. A plurality of supporting rods 222 are provided on the inner wall of the outer shell, and the supporting rods are located directly below the sealing plate. When the secondary zinc oxide waste residue in the first mixing mechanism is sufficient, the sealing plate can be used to seal the filter frame, so that the secondary zinc oxide waste residue moves to the next mixing mechanism for mixing reaction.

[0026] Furthermore, a pull ring 226 is provided on one side of the blocking plate.

[0027] In at least one embodiment, a plurality of supporting legs 3 are provided at the bottom of the discharge channel.

[0028] Working mode: large pieces of secondary zinc oxide waste slag first pass through the crushing mechanism and then fall on the first filter frame. If this place is not blocked by the blocking plate, the secondary zinc oxide waste slag falls into the mixing mechanism, wherein the liquid inlet of the mixing mechanism is injected with disodium ethylenediaminetetraacetic acid solution to react with the secondary zinc oxide waste slag. When the secondary zinc oxide waste slag reaches the amount, the blocking plate blocks the filter frame at this place, so that the subsequent secondary zinc oxide waste slag falls into the second mixing mechanism. Because the filter frame is provided with a number of long discharge holes, if the secondary zinc oxide waste slag after crushing still cannot be discharged from the long discharge holes, the secondary zinc oxide waste slag needs to be crushed again when discharged from the discharge channel.

[0029] Except for the technical features described in the specification, all other technical features are known technologies to those skilled in the art.
