Embodiment 1

[0028] Embodiment 1 introduces a kind of concentration equipment used in the process of producing high-purity nickel nitrate with ABS metal-plated material. The main device includes a concentration kettle body 1, an exhaust pipe 2 and a condenser 3, and its exhaust pipe 2 is connected to the concentration kettle. The top of the body 1 is connected, the condenser 3 is connected with the exhaust pipe 3, and the cooling medium of the condenser 3 is cold air, and the inner condenser pipe is of S-shaped design (not shown in the figure). A feeding port 5 is provided on the top of the concentration kettle body 1 beside the exhaust pipe 2, and the nickel nitrate solution is put into the concentration kettle body 1 through the feeding port 5.

[0029] An outer shell layer 4 is arranged on the circumferential surface of the concentrating kettle body 1, and a steam heating chamber (not marked in the figure) is formed between the outer shell layer 4 and the middle section of the circumfere...

Embodiment 2

[0032] Example 2 is a certain improvement made on the basis of Example 1, and its main purpose is that with the concentration of the nickel nitrate solution, the liquid amount inside the concentrated kettle body 1 is reduced. If the space of the steam heating chamber is kept unchanged, then It is necessary to continue to introduce a large amount of high-temperature steam, and the high-temperature steam at the upper end of the steam heating chamber cannot be fully utilized, which greatly increases its power consumption. Therefore, a servo motor 17 is fixed on the upper end side of the concentrating kettle body 1, and a sealed bearing 18 is arranged on the upper surface of the outer shell layer 4. The output shaft of the servo motor 17 extends into the steam heating chamber through the sealed bearing 18, and is located in the steam heating chamber. The lower end of the output shaft of the servo motor 17 in the cavity is connected with a screw rod 19, an annular sealing plate 20 i...

Abstract

The invention belongs to the technical field of evaporation and concentration equipment, and particularly relates to concentration equipment used in the process of producing high-purity nickel nitrate from ABS metallized materials, the concentration equipment comprises a concentration kettle body, an exhaust pipe and a condenser, the exhaust pipe is connected with the top end of the concentration kettle body, the condenser is connected with the exhaust pipe, a charging hole is formed in the top end of the concentration kettle body beside the exhaust pipe, a shell layer is arranged on the circumferential surface of the concentration kettle body, a steam heating cavity is formed between the shell layer and the middle section of the circumferential surface of the concentration kettle body, a steam inlet pipe is connected to the lower surface of the shell layer, and a plurality of steam outlet pipes are connected to the upper surface of the shell layer; the influence of concentration at high pressure and high temperature on nickel nitrate crystallization can be prevented, uniform heating of the nickel nitrate solution can be accelerated, heat of high-temperature nitrogen can be transferred to the nickel nitrate solution, heating of the nickel nitrate solution is accelerated, the concentration time is shortened, and the concentration effect is excellent.

Description

technical field [0001] The invention belongs to the technical field of evaporation and concentration equipment, in particular to a concentration equipment used in the process of producing high-purity nickel nitrate with ABS metal-plated material. Background technique [0002] With the increasing number of automobiles in China, there are more and more ABS electroplating parts, and more and more ABS electroplating parts are scrapped in electroplating production. Therefore, the recovery of copper and nickel in ABS electroplating parts is to reduce costs and improve An important way of business efficiency. The recovery of nickel metal is mainly in the form of nickel nitrate. The main process steps include: crushing ABS electroplating parts, magnetic separation and screening, adding acid to dissolve, concentrating and crystallization, and filtering and drying five steps. Control is particularly important in the process of heating and concentrating nickel nitrate, because the nic...
