[0041] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0042] Embodiment 1

[0043] Refer to Figures 1 to 3 , a chloride system oxide production system, including a reaction module 1, a solid-liquid separation module 2, a drying module 3, and a calcination module 4 connected in sequence;

[0044] The reaction module 1 is used to react a first solution containing a soluble metal salt and a second solution containing carbonate or bicarbonate to obtain a mixture containing a carbonate metal salt precipitate;

[0045] The solid-liquid separation module 2 is used to separate the metal carbonate precipitate from the mixture to obtain the metal carbonate precipitate;

[0046] The drying module 3 is used to dry the metal carbonate precipitate;

[0047] The calcination module 4 is used to pyrolyze the metal carbonate precipitate to form metal oxides.

[0048] The first solution is a solution containing a soluble metal salt, and the soluble metal salt can be selected from metal chlorides such as calcium chloride, magnesium chloride, zinc chloride, etc. (since this application is applicable to a chloride system, metal chlorides are selected as the soluble metal salt component in the first solution). Specifically, in this application, the soluble metal salt used is calcium chloride;

[0049] At the same time, on the one hand, since this application states that the first solution is a solution containing a soluble metal salt, and a poorly soluble metal carbonate precipitate can be formed after the first solution reacts with the second solution, therefore, implicitly, the first solution in this application is not a potassium salt solution or a sodium salt solution (because potassium carbonate and sodium carbonate are soluble in water and no metal carbonate precipitate will be formed);

[0050] On the other hand, this application does not impose too many restrictions on the specific selection of the soluble metal salt contained in the first solution, as long as it is a metal chloride (since this application is applicable to a chloride system) and the metal ions it contains can form a poorly soluble metal carbonate precipitate with carbonate or bicarbonate ions; that is, the soluble metal salt in the first solution can stably exist in the first solution in the form of metal ions and can form a poorly soluble metal carbonate precipitate after being mixed with the second solution containing carbonate or bicarbonate ions.

[0051] Under this design, first, the second solution is added to the reaction module 1, and then the first solution is added to the reaction module 1. After a mixture containing the metal carbonate precipitate is formed in the reaction module 1, the mixture in the reaction module 1 is sent to the solid-liquid separation module 2, where the solid-liquid separation is completed. After the metal carbonate precipitate is obtained, the separated metal carbonate precipitate is dried by the drying module 3, and finally, the dried metal carbonate precipitate is calcined by the calcination module 4 to pyrolyze the metal carbonate precipitate into metal oxides; in this way, each process step in the production process is automatically completed, improving production efficiency and reducing safety hazards.

[0052] Preferably, the solid-liquid separation module 2 and the drying module 3 transfer materials through the conveying module 5;

[0053] The conveying module 5 includes a screw conveyor 51, a conveyor belt 53, and a collection box 52 placed on the conveyor belt 53. The screw conveyor 51 can receive the metal carbonate precipitate separated from the solid-liquid separation module 2, and the collection box 52 is moved into or out of the drying module 3 by an external handling device;

[0054] The conveyor belt 53 is used to drive the collection box 52 to reciprocate between a first position and a second position. When the collection box 52 is in the first position, it can collect the metal carbonate precipitate dropped by the screw conveyor 51; when the collection box 52 is in the second position, the calcination module 4 can extract the metal carbonate precipitate in the collection box 52 for calcination.

[0055] Specifically, the metal carbonate precipitate dropped from the centrifuge 21 is first received by the screw conveyor 51, and then under the action of the screw conveyor 51, the metal carbonate precipitate is conveyed into the collection box 52 at the first position of the conveyor belt 53. Then, the external handling device moves the collection box 52 into the drying module 3 and dries it in the drying module 3. After drying, the external handling device moves the collection box 52 out and places the collection box 52 back on the conveyor belt 53. Then, the conveyor belt 53 conveys the collection box 52 to the second position, and the calcination module 4 extracts the metal carbonate precipitate in the collection box 52 for calcination. After the calcination module 4 extracts all the metal carbonate precipitate in the collection box 52, the conveyor belt 53 conveys the collection box 52 back to the first position again.

[0056] In this embodiment, the solid-liquid separation module 2 includes a centrifuge 21, a liquid storage tank 22, and a first liquid storage tank 23 connected to the reaction module 1;

[0057] The liquid storage tank 22 is provided with a first feed pipe 221 and a first discharge pipe 222. The first feed pipe 221 is connected to the liquid outlet of the centrifuge 21, and the first discharge pipe 222 is connected to the first liquid storage tank 23. An electrical conductivity sensor 2221 and a delivery pump are provided on the first discharge pipe 222. The delivery pump is used to convey the liquid in the liquid storage tank 22 into the first liquid storage tank 23 for storage.

[0058] Specifically, the material enters the centrifuge 21 through the first discharge pipe 222. Since the metal carbonate precipitate will carry chloride ions, in order to determine whether the metal carbonate precipitate in the centrifuge 21 is cleaned, the liquid thrown out by the centrifuge 21 will be stored in the liquid storage tank 22, and then the liquid in the liquid storage tank 22 is pumped out by the first delivery pump 2222 and collected in the first liquid storage tank 23. At the same time, the electrical conductivity sensor 2221 is used to detect the conductivity to determine whether the cleaning is qualified.

[0059] More preferably, the drying module 3 is an oven. The drying of the metal carbonate precipitate is completed by the oven.

[0060] In practical applications, the calcination module 4 includes a first vacuum feeder 41, a first screening machine 42, a second vacuum feeder 43, a manipulator 44, and a bell jar furnace 45;

[0061] The first vacuum feeder 41 is used to convey the precipitated metal carbonate salt after drying in the collection box 52 to the first screening machine 42, and the first screening machine 42 is used to screen out the large-particle precipitated metal carbonate salt to obtain the small-particle precipitated metal carbonate salt;

[0062] A container 6 is arranged below the discharge port of the second vacuum feeder 43, and the second vacuum feeder 43 is used to convey the small-particle precipitated metal carbonate salt after screening to the container 6;

[0063] The manipulator 44 is used to move the container 6 into or out of the bell jar furnace 45; the bell jar furnace 45 calcines the precipitated metal carbonate salt to pyrolyze the precipitated metal carbonate salt into metal oxide.

[0064] Specifically, since there may be a situation of pseudo-agglomeration in the precipitated metal carbonate salt after drying, in order to avoid the excessive amount of precipitated metal carbonate salt in the container 6 after calcination, first, the first vacuum feeder 41 extracts the precipitated metal carbonate salt in the collection box 52 at the second position and conveys it to the first screening machine 42. After the first screening machine screens out the small-particle precipitated metal carbonate salt, the second vacuum feeder 43 conveys the small-particle precipitated metal carbonate salt. At the same time, the manipulator 44 takes out the container 6 from the placement area of the container 6 and places the container 6 under the discharge port of the second vacuum feeder 43. In this way, the small-particle precipitated metal carbonate salt will be conveyed into the container 6. After the container 6 is filled with a certain amount of precipitated metal carbonate salt, the manipulator 44 moves the container 6 to the bell jar furnace 45 for calcination to pyrolyze the precipitated metal carbonate salt into metal oxide. After the calcination is completed, the manipulator 44 takes out the container 6 and places it in the designated area.

[0065] In this embodiment, the chloride system oxide production system further includes a third vacuum feeder 7, a crusher 8, a fourth vacuum feeder 9, a second screening machine 10, a fifth vacuum feeder 11, and a mixer 12;

[0066] The third vacuum feeder 7 is used to convey the metal oxide in the container 6 to the crusher 8;

[0067] The fourth vacuum feeder 9 is used to convey the crushed metal oxide to the second screening machine 10;

[0068] The second screening machine 10 is used to screen out the large-particle metal oxide to obtain the small-particle metal oxide;

[0069] The fifth vacuum feeder 11 is used to convey the small-particle metal oxide to the mixer 12 for mixing.

[0070] Further, in order to meet the requirements of the customer for uniformity and granularity, the metal oxide in the container 6 is extracted by the third vacuum loader 7 and conveyed to the crusher 8 for crushing. After crushing, the crushed metal oxide is conveyed to the second screening machine 10 by the fourth vacuum loader 9. The second screening machine 10 will screen out the large - particle metal oxide, and then the small - particle metal oxide is conveyed to the mixer 12 by the fifth vacuum loader 11 to improve the uniformity.

[0071] Preferably, the chloride - based oxide production system further includes a cyclone dust collector 13. The cyclone dust collector 13 is provided with a first negative - pressure pipe 131 for extracting the escaping dust during the feeding of the fourth vacuum loader 9; a second negative - pressure pipe 132 for extracting the escaping dust during the feeding of the fifth vacuum loader 11 is provided on the first negative - pressure pipe 131.

[0072] Specifically, during the feeding process, there will be a situation of dust escaping. Therefore, in order to reduce the dust pollution of the working environment, the first negative - pressure pipe 131 and the second negative - pressure pipe 132 of the cyclone dust collector 13 are used for dust collection treatment, thereby reducing the situation of dust escaping during the feeding of the fourth vacuum loader 9 and the fifth vacuum loader 11.

[0073] More preferably, the reaction module 1 includes a reaction tank 101 having a stirring mechanism. The reaction tank 101 is provided with a second feed pipe 102 for inputting the first solution, a third feed pipe 103 for inputting the second solution, a pH sensor 104, a liquid - level sensor 106 and a temperature sensor 105;

[0074] An outer coil 109 is provided on the outer wall of the reaction tank 101, and the reaction tank 101 can be heated by passing steam into the outer coil 109.

[0075] A second discharge pipe 107 connected to the solid - liquid separation module 2 is provided at the bottom of the reaction tank 101, and a second delivery pump 1071 is provided on the second discharge pipe 107.

[0076] Further, the second solution is first input into the reaction tank 101 through the second feed pipe 102 and the liquid level is controlled by the liquid - level sensor 106. Then the first solution is input into the reaction tank 101 through the first feed pipe 221, and the pH sensor 104 is used to detect whether the pH value in the reaction tank 101 is qualified. If the pH value is unqualified, the second solution is replenished. After the metal carbonate salt precipitate is formed in the reaction tank 101, the second delivery pump 1071 is started to convey the mixture containing the metal carbonate salt precipitate in the reaction tank 101 to the solid - liquid separation module 2 for separation;

[0077] Moreover, in order to accelerate the reaction rate in the reaction tank 101, steam is introduced into the external coil 109 through an external steam input device to heat the reaction tank 101, and workers can detect the temperature of the reaction tank 101 through the temperature sensor 105 to avoid excessive temperature.

[0078] Preferably, the solid-liquid separation module 2 further includes a heat exchanger 24 and a second liquid storage tank 25 for storing water. The heat exchanger 24 is provided with a first pipeline 241 and a second pipeline 242. One end of the first pipeline 241 is connected to an external steam input device, and one end of the second pipeline 242 is connected to the centrifuge 21, and the other end is connected to the second liquid storage tank 25;

[0079] The heat exchanger 24 is used to exchange heat between steam and water to pass hot water into the centrifuge 21.

[0080] Specifically, when cleaning the carbonate metal salt precipitate in the centrifuge 21, hot water can more efficiently clean the chloride ions on the carbonate metal salt precipitate. Therefore, during cleaning, the water in the second liquid storage tank 25 enters the heat exchanger 24 through the second pipeline 242, and then the steam will exchange heat with the water, and the heat-exchanged water will enter the centrifuge 21.

[0081] Preferably, the chloride-based oxide production system further includes a spray tower 14. The reaction module 1 is provided with a connecting pipe 108 connected to the spray tower, and the connecting pipe 108 is provided with a wind pressure sensor 1081 and a centrifugal fan 1082.

[0082] Furthermore, waste gas is generated when the first solution and the second solution are mixed in the reaction module 1. Therefore, the waste gas in the reaction module 1 is led out through the centrifugal fan 1082, and thus the waste gas will enter the spray tower 14 along the connecting pipe 108 for waste gas treatment. At the same time, the pressure in the connecting pipe 108 can be detected through the wind pressure sensor 1081.

[0083] Implicitly, in order to control the on / off of the output and input, valves are provided in the second feed pipe 102, the third feed pipe 103, and the second pipeline 242.

[0084] The above is only the preferred embodiment of the present invention.
