Description

Technical Field

[0001] This utility model relates to the field of nickel wastewater recovery technology, and in particular to a nickel wastewater recovery device. Background Technology

[0002] Nickel wastewater is generally divided into two categories: electroplating nickel wastewater, in which nickel exists in the form of nickel ions, and chemical nickel plating wastewater, in which nickel ions combine with complexing agents to form complex bonds. At the same time, the wastewater contains a large amount of hypophosphite ions. Electroplating wastewater has a simple composition, and the nickel in it exists in the form of ions. Nickel in chemical nickel plating wastewater is a strong carcinogen. When discharged into water bodies, it will disrupt the ecological balance of the water body, threaten the normal growth of aquatic organisms, cause eutrophication, and also precipitate and adsorb into the food chain, ultimately endangering human health. Therefore, nickel wastewater needs to be treated.

[0003] Current nickel wastewater recovery devices recycle nickel wastewater by adding chemical reagents. The reaction between the chemical reagents and the nickel wastewater takes time. Stirring is generally used to speed up the reaction, but the stirring method is relatively simple, usually stirring in a fixed position, which is not thorough enough and reduces the treatment effect. Utility Model Content

[0004] The purpose of this invention is to solve the problem that the stirring method is relatively simple, generally stirring in a fixed position, which is not enough to fully stir and reduces the treatment effect. Therefore, a nickel wastewater recovery device is proposed.

A belt is connected between the first rotating shaft and the first stirring shaft. A first gear is fixedly connected to the first rotating shaft, and a toothed plate is fixedly connected to the inner wall of the slide rail. The first gear meshes with the toothed plate.

[0008] To achieve better mixing, two symmetrically arranged second rotating shafts are rotatably mounted on the fixed plate. The outer walls of the second rotating shafts are fixedly connected with stirring blades and second gears, and the second gears mesh with the first gears.

[0009] For better mixing effect, preferably, a third gear is fixedly connected to the first mixing shaft, the third gear meshes with a fourth gear, a gear ring is fixedly connected to the bottom of the fixed plate, and the fourth gear meshes with the gear ring. A second mixing shaft is fixedly connected to the fourth gear, the second mixing shaft is mounted on the fixed plate, and a second mixing rod is fixedly connected to the second mixing shaft.

[0010] In order to limit the second stirring shaft, preferably, a limiting plate is fixedly connected to one end of the second stirring shaft near the fixed plate. The bottom and the inside of the fixed plate are respectively provided with a sliding groove and a limiting groove, and the second stirring shaft and the limiting plate are respectively sleeved in the sliding groove and the limiting groove.

[0011] To effectively transport nickel wastewater, preferably, a conveying pipe is fixedly connected between the inlet of the filter box and the outlet of the water tank, a one-way valve is installed on the conveying pipe, and a drain pipe is fixedly connected to the outlet of the filter box.

The water tank 1 is provided with a driving part that drives the first stirring rod 204 to rotate and the slider 202 to slide laterally on the slide rails 201.

[0027] Specifically, the drive unit drives the first stirring rod 204 to rotate, which in turn drives the slider 202 to slide laterally on the slide rail 201. The slider 202 then drives the first stirring rod 204 to move synchronously, thereby enabling the first stirring rod 204 to move and stir, resulting in more thorough stirring and improved processing efficiency.

[0028] The drive unit includes a motor 206 fixedly connected to the top of the fixed plate 203, a first stirring shaft 205 fixedly connected to the output end of the motor 206, two symmetrically arranged first rotating shafts 207 rotatably mounted on the fixed plate 203, and a belt 208 drivingly connecting the first rotating shafts 207 and the first stirring shafts 205.

Since the first gear 209 is meshed with the toothed plate 210, the slider 202 slides laterally on the slide rail 201.

[0030] Two symmetrically arranged second rotating shafts 211 are rotatably mounted on the fixed plate 203. The outer wall of the second rotating shaft 211 is fixedly connected to a stirring blade 212 and a second gear 213. The second gear 213 meshes with the first gear 209.

[0031] Specifically, the second gear 213 drives the second shaft 211 to rotate the stirring blade 212, and the direction of rotation of the stirring blade 212 is opposite to that of the first stirring rod 204, which is used to assist in stirring and make the stirring more thorough and uniform.

[0033] Specifically, under the transmission of the third gear 301, the gear ring 302 and the fourth gear 303, the second stirring shaft 304 drives the second stirring rod 305 to rotate on its own axis while also rotating around the first stirring shaft 205, thus performing planetary motion and further improving the stirring effect.

[0034] A limiting plate 5 is fixedly connected to one end of the second stirring shaft 304 near the fixed plate 203. The bottom and the inside of the fixed plate 203 are respectively provided with a sliding groove 6 and a limiting groove 7. The second stirring shaft 304 and the limiting plate 5 are respectively fitted into the sliding groove 6 and the limiting groove 7. The diameter of the limiting plate 5 is larger than the diameter of the second stirring shaft 304, so that the second stirring shaft 304 will not fall off. The sliding groove 6 and the limiting groove 7 are used to satisfy the movement of the second stirring shaft 304.

[0035] A conveying pipe 8 is fixedly connected between the inlet of the filter box 4 and the outlet of the water tank 1. A one-way valve 9 is installed on the conveying pipe 8.

The filter plate 12 is used to filter out nickel metal for recycling. The frame 11 is used to prevent nickel metal from falling from the sides of the filter plate 12 when it is disassembled.

[0036] Specifically, after the treatment is completed, open the one-way valve 9, and the sewage in the pool 1 will be discharged through the conveying pipe 8, the filter box 4 and the drain pipe 10. The nickel metal will fall onto the filter plate 12. Remove the positioning rod 13, and remove the frame 11 and the filter plate 12 to obtain the nickel metal.
