MIXING CHAMBER FOR EXTRACTION BOX FIELD

The present disclosure relates to the field of extraction equipment, and more particularly,

to a mixing chamber for an extraction box.

BACKGROUND

An existing mixing chamber for an extraction box includes a casing and a latent chamber.

The existing latent chamber runs well when no solid matters are produced. When solid

matters are produced during the extraction process (for example, the production process of

metals like nickel, cobalt, zinc and indium), the solution entering the extraction box contains

calcium ions. During the extraction process, gypsum slag is precipitated when the calcium

ions are in contact with sulfate ions. The precipitated gypsum slag will be deposited on an

inner wall of the mixing cavity, in the latent chamber and on the surface of a stirring rod. As

the production progresses, the gypsum slag needs to be cleaned out regularly. When cleaning

the solid deposit, the production needs to be stopped for cleaning a trough, workers enter the

trough to shovel the solid matters out of the trough manually, resulting in affecting the whole

production.

may be fixed connections, detachable connections or integral connections; may be mechanical

connections or electrical connections; may be direct connections, indirectly connected with each other through an intermediate medium, or communications inside two elements or an interaction relationship of two elements. A person of ordinary skill in the art may understand specific meanings of the foregoing terms in this disclosure according to a specific situation. A mixing chamber for an extraction box 10 according to embodiments of the present disclosure is described with reference to Fig. 1. As illustrated in Fig. 1, the mixing chamber for an extraction box 10 according to an embodiment of the present disclosure includes a casing 110, a duct 120, a slag-removing hopper 150 and a suction device (not illustrated). The casing 110 defines a mixing cavity 111 at an upper portion therein and a latent chamber 112 at a lowerportion therein. The casing 110 defines a raw liquid inlet 113 and an extractant inlet 114 on a side wall. The duct 120 is arranged in the latent chamber 112 and in communication with the raw liquid inlet 113, the extractant inlet 114, the mixing cavity 111 and the latent chamber 112. The slag-removing hopper 150 is arranged at the bottom of the casing 110 and is formed into a taper hopper in a direction away from the casing 110. The slag-removing hopper 150 has a slag-removing outlet 151 for discharging solid matters. The suction device is configured to suck liquid from the duct 120 into the mixing cavity 111. It should be understood that, a raw liquid and an extractant enter the duct 120 through the raw liquid inlet 113 and the extractant inlet 114 respectively, and then enter the mixing cavity 111 under the suction of the suction device. In the mixing cavity 111, the raw liquid and the extractant are sufficiently mixed, and precipitated solid matters fall into the slag-removing hopper 150 under gravity. Due to that the slag-removing hopper 150 is taper in shape, the precipitated solid matters slide down towards the slag-removing outlet 151, such that a worker only needs to clean the slag-removing outlet 151 regularly. In this manner, the cleaning is convenient and it is unnecessary to stop the production, thereby improving the working efficiency. In addition, compared with the existing mixing chamber for an extraction box, the duct 120 replaces a latent chamber plate, such that there is no blind spot in the latent chamber 112 and the difficulty of cleaning the mixing chamber for an extraction box 10 is reduced.

For the mixing chamber for an extraction box 10 according to embodiments of the present disclosure, the slag-removing hopper 150 is formed into a taper hopper, such that precipitated solid matters may fall at the slag-removing outlet 151 under theirs gravity. In this manner, there is no blind spot about slag in the whole mixing chamber for an extraction box

10. The worker only needs to clean the slag-removing outlet 151 regularly, and the mixing

chamber for the extraction box 10 may be cleaned easily without being shut down, thereby

improving the working efficiency and ensuring stirring and suction while the slag is cleaned

smoothly.

In some embodiments, as illustrated in Fig. 1, the raw liquid inlet 113 and the extractant

inlet 114 are arranged on opposite side walls of the casing 110. The mixing chamber for an

extraction box 10 further includes a first transverse pipe 130 and a second transverse pipe 140.

Two ends of the first transverse pipe 130 are in communication with the raw liquid inlet 113

and the duct 120 respectively, and two ends of the second transverse pipe 140 are in

communication with the extractant inlet 114 and the duct 120 respectively. It should be

understood that in this case, it may be guaranteed that the raw liquid and the extractant enter

the mixing cavity 111 through the duct 120. In addition, as the raw liquid and the extractant

enter the duct 120 from opposite directions, the mixing uniformity of the raw liquid and the

extractant entering the mixing cavity 111 is increased to some extent, thereby improving the

production efficiency indirectly.

In some embodiments, as illustrated in Fig. 1, the duct 120 is provided with a first

_0 communication port 121 in communication with the first transverse pipe 130 and a second

communication port 122 in communication with the second transverse pipe 140 at two

opposite side walls respectively. The duct 120 has an open upper end in communication with

the mixing cavity 111, and an open lower end in communication with the latent chamber 112.

It should be understood that there is no residual slag in the duct 120 as the upper end of the

duct 120 is open and in communication with the mixing cavity and the lower end of the duct

120 is open and in communication with the latent chamber 112. The duct 120 remains clean

after the mixing chamber for an extraction box 10 operates for a period of time, such that

there is no need to stop the production for cleaning and the operation efficiency is thus

improved.

In some specific embodiments, as illustrated in Fig. 1, the duct 120 is provided with a separation plate 123 therein. The separation plate 123 divides the duct 120 into a first cavity

124 and a second cavity 125 spaced apart from each other. The first cavity 124 is in

communication with the first transverse pipe 130, and the second cavity 125 is in

communication with the second transverse pipe 140. It should be understood that since an

interior of the duct 120 is divided into the first cavity 124 and the second cavity 125, the raw

liquid and the extractant cannot be mixed in the duct 120 after entering the duct 120. Only

when the raw liquid and the extractant leave the duct 120 and enter the mixing cavity 111 can

they be mixed. In this manner, an extraction reaction between the raw liquid and the

extractant may be prevented, and thus the production efficiency will not be affected by solid

slag accumulated in the duct 120.

In some embodiments, the duct 120 partially extends into the slag-removing hopper 150.

The duct 120 is connected to the casing 110 or the slag-removing hopper 150 via a connector

160. The duct 120 may be connected in the casing 110 rather stably. It should be noted that

the connector 160 herein only functions as connecting the duct 120 to the casing 110 or the

slag-removing hopper 150, and no specific limitations is made to the connector 160. In other

words, the type of the connector 160 may be selected according to practical requirements.

In some embodiments, the slag-removing hopper 150 has a circular cross section, and the

slag-removing outlet 151 is arranged at the center of the slag-removing hopper 150. The solid

matters and slag may slide down towards the slag-removing outlet 151 successfully. Certainly,

-0 it should be noted that the cross section of the slag-removing hopper 150 may be of other

shapes, for example, a trapezoid.

In some embodiments, the mixing cavity 111 is further provided with a stirring device

(not illustrated). The raw liquid and the extractant are mixed uniformly, and the operation

efficiency is improved.

A mixing chamber for an extraction box 10 according to a specific embodiment of the

present disclosure is described with reference to Fig. 1 as follows.

As illustrated in Fig. 1, the mixing chamber for an extraction box 10 according to this

embodiment of the present disclosure includes a casing 110, a duct 120, a slag-removing

hopper 150 and a suction device (not illustrated). The casing 110 defines a mixing cavity 111

at anupperportion therein and a latent chamber 112 at a lowerportion therein. The casing 110 defines a raw liquid inlet 113 and an extractant inlet 114 on opposite side walls. The duct 120 is arranged in the latent chamber 112 and in communication with the raw liquid inlet 113 and the extractant inlet 114 via a first transverse pipe 130 and a second transverse pipe 140 respectively. The duct 120 has an open upper portion and an open lower portion, such that the duct 120 is in communication with the mixing cavity 111 via the upper portion and in communication with the latent chamber 11 via the lower portion. The duct 120 is provided with a separation plate 123 therein. The separation plate 123 divides the duct 120 into a first cavity 124 and a second cavity 125 spaced apart from each other. The first cavity 124 is in communication with the first transverse pipe 130, and the second cavity 125 is in communication with the second transverse pipe 140. The slag-removing hopper 150 is arranged at a bottom of the casing 110 and is formed into a taper hopper in a direction away from the casing 110. The slag-removing hopper 150 has a slag-removing outlet 151 for discharging solid matters. The suction device is configured to suck a liquid from the duct 120 into the mixing cavity 111. As for the mixing chamber for an extraction box 10 according to this embodiment, there are improvements on a traditional latent chamber. A latent chamber plate is removed and replaced by the duct 120. There is no top plate on the upper portion of the duct 120 and no bottom plate on the lower portion. Compared with the traditional latent chamber, there is no blind spot in the latent chamber 112 of the mixing chamber for an extraction box according to _0 this embodiment. In addition, since the slag-removing hopper 150 is connected to the bottom of the casing 110, the slag produced during the production may be accumulated at the bottom of the slag-removing hopper 150 naturally, such that solid matters may be discharged through the slag-removing outlet 151 at the bottom of the slag-removing hopper 150 on a regular basis. In this manner, the production may be performed continuously as there is no need to stop the production. Though the bottom of the casing 110 is provided with the slag-removing hopper 150, a mixing-stirring suction manner may remain the same, thereby facilitating two phases of oil and water entering the mixing cavity 111 smoothly.
