Description

Technical Field

[0001] This utility model relates to the field of chemical equipment technology, specifically a low-temperature synthesis reactor for gold beneficiation agents. Background Technology

[0002] Gold beneficiation agents are core chemical auxiliary materials used in the gold mining and beneficiation process to separate, leach, or enrich gold elements. By adjusting the slurry environment, changing the surface properties of gold minerals, or reacting directly with gold ions, they achieve efficient gold extraction. Their performance directly determines the beneficiation recovery rate, production cost, and environmental compliance.

[0003] Chinese Patent Publication No. CN207119362U discloses a low-temperature reaction vessel, which includes a low-temperature reaction vessel body, a low-temperature control device, a stirring device, and a centrifugal solid-liquid separation device. The low-temperature control device includes an alcohol tank, an electrically controlled valve, and a rotary atomizing nozzle. The stirring device includes a pair of electric sliding tables, a pair of stirring blade frames, and a pair of fan-type stirring blades. The centrifugal solid-liquid separation device includes a centrifugal solid-liquid separator, a crystal material tank, and a solution material tank.

[0004] The aforementioned low-temperature reactor uses stirring blades to agitate the materials within the reactor. However, when processing the raw materials for gold ore beneficiation agents, low-boiling-point organic additives are required during processing. Even at low temperatures, these organic additives will still volatilize due to molecular thermal motion. Furthermore, some raw materials undergo controlled decomposition or chemical reactions during the low-temperature reaction, generating byproduct gases. Simultaneously, the gases carry away some molecularized materials. The aforementioned low-temperature reactor cannot promptly discharge the gases or recover the molecularized materials from the gases, leading not only to an increase in pressure within the reactor but also to material waste. Utility Model Content

By using a connecting chamber and a connecting pipe, the gas in the reactor is discharged to prevent the pressure in the reactor from increasing. At the same time, the gas moves along the inner wall of the inclined inner cover, and the molecularized materials in the gas condense into water droplets on the inner wall of the inner cover and slide back into the inner reactor shell, thereby solving the technical problems mentioned in the background art.

Detailed Implementation

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0038] Please see Figure 1-15In this embodiment of the invention, a low-temperature synthesis reactor for gold beneficiation agents includes...

[0039] The reactor structure 2 is used to process gold beneficiation agent raw materials. The top of the reactor structure 2 is fixedly connected to the condenser structure 1. Multiple support legs 4 are evenly fixedly connected to the outside of the reactor structure 2.

[0040] The stirring structure 3 is used to stir the raw materials of gold beneficiation agent. The stirring structure 3 is fixedly connected to the top of the condensing vessel structure 1, and the end of the stirring structure 3 away from the condensing vessel structure 1 is located inside the reaction vessel structure 2.

[0041] The condenser structure 1 includes a condenser shell 11, and an annular inner cover 13 is integrally provided on the upper inner side of the condenser shell 11. The cross-section of the inner cover 13 is inclined, and a flow guide plate 15 is integrally provided on the bottom of the inner cover 13. The flow guide plate 15 is integrally provided with the inner wall of the condenser shell 11, and a plurality of flow guide grooves 16 are evenly provided on the inner wall of the flow guide plate 15 in annular distribution.

[0042] The condenser shell 11 has a receiving cavity 17 at the end away from the inner cover 13 for receiving multiple conveying pipes 18. The top of each of the multiple conveying pipes 18 is fixedly connected to the guide plate 15, and the bottom of the guide plate 15 is provided with an annular collection groove 111. The multiple conveying pipes 18 are all connected to the collection groove 111.

[0043] The reactor structure 2 includes an outer shell 21, and an inner shell 23 is coaxially arranged inside the outer shell 21. An annular temporary storage tank 26 is fixedly connected to one end of the inner shell 23 near the condenser shell 11. Multiple annularly distributed diversion channels 27 are uniformly arranged inside the inner shell 23, and the multiple diversion channels 27 are all connected to the temporary storage tank 26.

[0044] The condenser shell 11 has a condensation chamber 14 at the end near the inner shell 23, which is in communication with the space inside the inner shell 23; a connecting chamber 10 is fixedly connected to the top side of the inner cover 13, and the end of the connecting chamber 10 away from the inner cover 13 is fixedly connected to the connecting pipe 110. The end of the connecting pipe 110 away from the connecting chamber 10 extends to the outside of the condenser shell 11 and is connected to the negative pressure unit; the connecting chamber 10 is in communication with the condensation chamber 14.

[0045] The top of the condenser shell 11 is uniformly and fixedly connected with multiple feed pipes 19, one end of which extends into the condensation chamber 14, and the other end of which is connected to the gold ore beneficiation agent raw material supply equipment through a pipeline; the bottom of the condenser shell 11 is coaxially and fixedly connected with an upper flange 12.

[0046] By adopting the above technical solution, when the raw materials react in the reactor structure to produce gas, due to the inclined setting of the inner cover 13 and the cooperation of the connecting chamber 10, the connecting pipe 110, and the negative pressure unit, the gas can move from the inner shell 23 to the condensing chamber 14, and then move along the inner wall of the inner cover 13 into the connecting chamber 10, so that the gas can be discharged from the reactor in time, preventing the pressure inside the reactor from increasing. At the same time, the molecularized materials in the gas will condense into water droplets when they encounter cold on the inner wall of the inner cover 13. These water droplets will slide down the inclined inner wall of the inner cover 13 to the guide plate 15, and then enter the collection tank 111 through the guide groove 16 on the guide plate 15. Finally, they will flow through multiple conveying pipes 18 to the temporary storage tank 26 inside the inner shell 23, and then participate in the reaction again through multiple guide grooves 27, realizing the recycling of materials and avoiding waste of materials.

[0047] Furthermore, the "low temperature" in the low-temperature synthesis reactor used for gold ore beneficiation agent production is not the low temperature perceived by the human body, such as a cold environment of 0-20℃, but rather a medium-low temperature range defined by process requirements, with a core range of 5-200℃. In contrast, the process temperature range for high-temperature roasting of gold ore beneficiation agents is 500-900℃. Therefore, the low temperature in the low-temperature reactor is fundamentally different from the low temperature perceived by the human body. For example, organic additives such as organic amine catalysts have a boiling point of 50-120℃, so even in a low-temperature reactor, gas will still be generated. In addition, industrial-grade raw materials such as thiourea and sodium bicarbonate contain trace amounts of low-boiling-point impurities such as residual methanol and ethanol, which will volatilize with the raw materials during stirring, dissolution, or reaction, forming mixed waste gas.

[0048] In this embodiment, a wrapping shell 22 is provided between the outer vessel shell 21 and the inner vessel shell 23, and the wrapping shell 22 is fixedly connected to the outer wall of the inner vessel shell 23; a heating chamber 24 is located between the inner vessel shell 23 and the wrapping shell 22, and a heat preservation chamber 25 is located between the wrapping shell 22 and the outer vessel shell 21; a lower flange 212 is coaxially fixedly connected to the top of the outer vessel shell 21; and multiple stirring plates 213 are uniformly fixedly connected to the inner wall of the inner vessel shell 23.

[0049] The outer vessel shell 21 is symmetrically provided with connecting pipe 28 and connecting pipe 29 on both sides. Connecting pipe 28 is located at the end of the outer vessel shell 21 closer to the condensing vessel shell 11, and connecting pipe 29 is located at the end of the outer vessel shell 21 away from connecting pipe 28. Both connecting pipe 28 and connecting pipe 29 extend to the inside of the outer shell 22 and are connected to the heating chamber 24. Connecting pipe 28 is connected to the output end of the heating unit through a pipe, and connecting pipe 29 is connected to the input end of the heating unit through a pipe.

[0050] The outer vessel shell 21 is provided with a flushing pipe 210 on one side and a discharge port 211 at the bottom of the outer vessel shell 21. Both the flushing pipe 210 and the discharge port 211 are fixedly connected to the inner vessel shell 23 and communicate with the space inside the inner vessel shell 23. A temperature sensor 20 is fixedly connected to the side of the outer vessel shell 21 away from the flushing pipe 210. The temperature sensor 20 extends into the interior of the inner vessel shell 23.

[0051] The stirring structure 3 includes a rotating rod 31, which is coaxially disposed inside the inner vessel shell 23. A plurality of stirring blades 32 are uniformly fixedly connected to one end of the rotating rod 31 near the inner vessel shell 23. The other end of the rotating rod 31 away from the inner vessel shell 23 extends to the top of the condensing vessel shell 11 and is connected to the output end of the reducer unit 35.

[0052] The bottom of the reducer unit 35 is fixedly connected to the top of the mounting cylinder 34, and the bottom of the mounting cylinder 34 is fixedly connected to the top of the connecting seat 33. The bottom of the connecting seat 33 is sealed and fixedly connected to the top middle of the inner cover 13. The top middle of the condenser shell 11 is provided with a round hole for the connecting seat 33 to pass through, and the top of the connecting seat 33 is fixedly connected to the top middle of the condenser shell 11. The end of the rotating rod 31 near the reducer unit 35 is located inside the mounting cylinder 34, and the rotating rod 31 is rotatably connected to the mounting cylinder 34 through the bearing seat 36.

[0053] By adopting the above technical solution, the enclosing shell 22 set between the outer shell 21 and the inner shell 23 separates the heating chamber 24 and the heat preservation chamber 25. The heating chamber 24 cooperates with the heating unit through the connecting pipe 28 and the connecting pipe 29 to accurately control the temperature required for the reaction, while the heat preservation chamber 25 can reduce heat loss and ensure that the reaction is carried out in a stable temperature environment. The temperature sensor 20 can monitor the temperature inside the inner shell 23 in real time so that the operator can adjust the working status of the heating unit in a timely manner.

[0054] The working principle of this utility model is as follows: When the raw materials react in the reactor structure to produce gas, due to the inclined setting of the inner cover 13 and the cooperation of the connecting chamber 10, the connecting pipe 110 and the negative pressure unit, the gas can move from the inner shell 23 to the condensing chamber 14, and then move along the inner wall of the inner cover 13 into the connecting chamber 10, so that the gas can be discharged from the reactor in time to prevent the pressure inside the reactor from increasing. At the same time, the molecularized materials in the gas will condense into water droplets when they encounter cold on the inner wall of the inner cover 13. These water droplets will slide down the inclined inner wall of the inner cover 13 to the guide plate 15, and then enter the collection tank 111 through the guide groove 16 on the guide plate 15. Finally, they will flow through multiple conveying pipes 18 to the temporary storage tank 26 inside the inner shell 23, and then participate in the reaction again through multiple guide grooves 27, realizing the recycling of materials and avoiding waste of materials.

[0055] The outer shell 22 between the outer shell 21 and the inner shell 23 separates the heating chamber 24 and the heat preservation chamber 25. The heating chamber 24 is connected to the heating unit through connecting pipe 28 and connecting pipe 29, which can accurately control the temperature required for the reaction. The heat preservation chamber 25 can reduce heat loss and ensure that the reaction is carried out in a stable temperature environment. The temperature sensor 20 can monitor the temperature inside the inner shell 23 in real time so that the operator can adjust the working status of the heating unit in a timely manner.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
