Description

Technical Field

[0001] This utility model relates to a reaction field, specifically to an automatic sampling system for a leaching stirring tank. Background Technology

[0002] In gold ore beneficiation plants currently employing cyanide leaching, the leaching stirred tank is used as a container for the separation reaction between gold ore gangue minerals and gold metal. The slurry concentration in the tank is generally between 35% and 45%. Sodium cyanide is added to the slurry as a leaching agent, and activated carbon is added to adsorb the gold metal dissolved in the leached slurry. During production, samples need to be taken to test the concentration of CN- ions in the slurry, the gold grade in the solution, the gold grade in the granular ore, and the gold grade in the activated carbon.

[0003] In related technologies, sampling is troublesome and inefficient. Utility Model Content

[0004] This utility model is based on the inventor's discovery and understanding of the following facts and problems:

[0005] The sampling methods used in the relevant technologies are as follows: (1) Manually holding a long-handled container and scooping the top slurry from the top of the leaching mixing tank to take a sample. This method has a low degree of automation, high labor intensity, weak mineral sample representativeness, and is not conducive to safe production operation; (2) Using a submersible pump or liquid pump to extract slurry from the tank to take a sample. In this method, the pump impeller will be in direct contact with the slurry, and the rotating impeller is easy to crush the activated carbon in the slurry. During the test, the crushed activated carbon and solid ore particles are not easy to separate.

[0006] This utility model aims to at least partially solve one of the technical problems in the related art.

[0007] Therefore, embodiments of this utility model propose an automatic sampling system for leaching stirring tanks that has low sampling cost and high sampling efficiency.

[0008] An automatic sampling system for a leaching stirring tank according to an embodiment of the present invention includes: a reaction vessel having a reaction tank; and a sampling assembly including a suction element and a sampling element. The suction element is disposed on the reaction vessel, one end of which is located inside and communicates with the reaction tank so that the suction element adsorbs the reaction liquid within the automatic sampling system for the leaching stirring tank. The other end of the suction element is communicated with the sampling element so that the reaction liquid adsorbed by the suction element flows into the sampling element. One end of the suction element is movable relative to the reaction vessel in a vertical direction so that the suction element can adsorb reaction liquid at different heights within the reaction tank.

[0009] The automatic sampling system for leaching stirring tank of this utility model embodiment is equipped with a sampling component, which can automatically extract the reaction liquid in the reaction tank through the suction element, and realize the accurate extraction of reaction liquid at different heights in the reaction tank. Compared with related technologies, it improves the accuracy and reliability of sampling and improves the sampling efficiency.

[0010] In some embodiments, the aspiration device includes: a diaphragm pump disposed at the upper end of the reaction vessel and movable in the vertical direction relative to the automatic sampling system for the leaching stirring tank; and an aspiration tube, one end of which is connected to the diaphragm pump and the other end of which passes through the reaction tank so that the diaphragm pump can aspirate the reaction liquid in the reaction tank through the aspiration tube.

[0011] In some embodiments, the suction device further includes a telescopic frame, which is mounted on the reactor and the diaphragm pump is mounted on the telescopic frame. The telescopic frame is used to drive the diaphragm pump to move in the vertical direction.

[0012] In some embodiments, the suction tube includes a first section and a second section that are connected to each other. The first section is connected to the diaphragm pump and is located above the reaction liquid. The second section is located in the reaction tank and is located in the reaction liquid. The height of the reaction liquid is H, and the length of the second section is 3 / 4H.

[0013] In some embodiments, the sampling device includes a housing disposed on the reactor. The housing has an inlet and a first outlet. The inlet of the housing is connected to the diaphragm pump so that the reaction liquid flowing out of the diaphragm pump flows into the housing. The first outlet is used for sampling.

[0014] In some embodiments, the housing further has a second outlet, and the sampling element has a first state and a second state.

[0021] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0022] The automatic sampling system 100 for a leaching stirring tank according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0023] like Figure 1 As shown, the automatic sampling system 100 for a leaching stirring tank according to an embodiment of the present invention includes a reaction vessel 1 and a sampling component 2.

[0024] The reactor 1 has a reaction tank. The sampling assembly 2 includes a suction element 21 and a sampling element 22. The suction element 21 is located on top of the reactor 1. One end of the suction element 21 is located inside the reaction tank and communicates with it, so that the suction element 21 can adsorb the reaction liquid in the automatic sampling system 100 for leaching the stirring tank. The other end of the suction element 21 communicates with the sampling element 22, so that the reaction liquid adsorbed by the suction element 21 flows into the sampling element 22. One end of the suction element 21 is movable in the vertical direction relative to the reactor 1, so that the suction element can adsorb the reaction liquid at different heights in the reaction tank. Specifically, as shown... Figure 1 As shown, the reaction liquid (e.g., slurry) is placed in the reaction tank and stirred by the stirring blades inside the reaction tank. The suction component 21 is located at the upper end of the reaction vessel 1, and the inlet of the suction component 21 passes through the reaction tank and the reaction liquid. The suction component sucks up the reaction liquid in the reaction vessel 1. The sampling component 22 is located at the upper end of the reaction vessel 1, and the outlet of the suction component 21 is connected to the sampling component 22, so that the reaction liquid is sucked into the sampling component 22 and stored in the sampling component 22. When sampling is required, the sampling bottle can be connected to the sampling component 22, so that the reaction liquid in the sampling component 22 is extracted into the sampling component 22. The inlet of the suction component 21 moves in the vertical direction. By adjusting the position of the inlet of the suction component 21, the reaction liquid at different heights in the reaction tank can be extracted, thereby improving the sampling accuracy of the sampling component 22.

[0025] The automatic sampling system 100 for leaching stirring tank of this utility model embodiment is equipped with a sampling component 2, which can automatically extract the reaction liquid in the reaction tank through the suction member 21. Since there may be vertical differences in concentration, temperature or composition of the reaction liquid in the reaction tank, the up and down movement function of the suction member 21 realizes the accurate extraction of reaction liquid at different heights in the reaction tank. Compared with related technologies, the accuracy and reliability of sampling are improved, and the sampling efficiency is improved.

[0026] In some embodiments, the suction member 21 includes a diaphragm pump 211 and a suction tube 212.

[0027] The diaphragm pump 211 is located at the upper end of the reactor 1 and is movable vertically relative to the automatic sampling system 100 used for the leaching stirring tank. Since the diaphragm pump 211 has no mechanical rotating impeller and its moving parts do not directly contact the slurry, it does not cause impact or crushing of the activated carbon in the slurry. This ensures the service life of the suction element 21 and also contributes to the accuracy of subsequent laboratory tests.

[0028] One end of the suction pipe 212 is connected to the diaphragm pump 211, and the other end of the suction pipe 212 passes through the reaction tank so that the diaphragm pump 211 can draw the reaction liquid from the reaction tank through the suction pipe 212. Specifically, as shown... Figure 1 As shown, the inlet of the suction pipe 212 is inserted into the reaction tank and located in the reaction liquid, and the outlet of the suction pipe 212 is connected to the inlet of the diaphragm pump 211, so that the diaphragm pump 211 can draw the reaction liquid in the reaction tank through the suction pipe 212.

[0029] In some embodiments, the suction member 21 further includes a telescopic frame (not shown in the figure), which is mounted on the reactor 1 and the diaphragm pump 211 is mounted on the telescopic frame. The telescopic frame is used to drive the diaphragm pump 211 to move vertically. Specifically, as Figure 1As shown, the telescopic frame can be any of the electric telescopic frame, pneumatic telescopic frame or hydraulic telescopic frame. The telescopic frame is installed on the reactor 1 by fasteners. The reactor 1 is installed on the telescopic frame. By driving the telescopic frame to extend and retract, the suction component 21 can be moved in the up and down direction.

[0030] In some embodiments, the suction tube 212 includes a first section 2121 and a second section 2122 that are connected to each other. The first section 2121 is connected to the diaphragm pump 211 and is located above the reaction liquid. The second section 2122 is disposed in the reaction tank and located in the reaction liquid. The height of the reaction liquid is H, and the length of the second section 2122 is 3 / 4H. Specifically, as shown... Figure 1 As shown, the first section 2121 is located above the reaction tank and its outlet is connected to the diaphragm pump 211. The inlet of the first section 2121 is connected to the outlet of the second section 2122. The second section 2122 is a vertical section and at least partially penetrates the reaction liquid. The length of the second section 2122 is 3 / 4H, which can draw reaction liquid from different heights of the reaction tank, helping to obtain more representative samples and improving the accuracy and reliability of sampling.

[0031] In some embodiments, the sampling device 22 includes a housing 221, which is disposed on the reactor 1. The housing 221 has an inlet and a first outlet. The inlet of the housing 221 is connected to a diaphragm pump 211 so that the reaction liquid flowing out of the diaphragm pump 211 flows into the housing 221. The first outlet is used for sampling. Specifically, as shown... Figure 1 As shown, the box 221 is a liquid storage tank and can be installed on the reactor 1 by a mounting bracket. The inlet of the box 221 is connected to the outlet of the diaphragm pump 211, so that the reaction liquid in the reactor 1 flows into the box 221 and is stored in the box 221. The first outlet can be used for sampling, so that the reaction liquid in the box 221 flows into the sampling bottle.

[0032] In some embodiments, the housing 221 further has a second outlet, and the sampling member 22 has a first state and a second state. In the first state, the first outlet is adapted to communicate with a sampling tube, and the second outlet is closed, so that the reaction liquid in the housing 221 flows into the sampling tube through the first outlet. In the second state, the first outlet is closed, and the second outlet is communicated with the reaction vessel 1, so that the reaction liquid in the housing 221 flows into the reaction vessel 1 through the second outlet. Specifically, in the first state, the first outlet of the housing 221 is communicated with the sampling tube, so that the reaction liquid in the sampling bottle flows into the sampling bottle for sampling. In the second state, the second outlet is communicated with the reaction vessel 1, so that the reaction liquid in the housing 221 flows into the reaction vessel 1 for recovery of the reaction liquid.

[0033] In some embodiments, a first outlet is formed at the lower end of the housing 221. This allows the operator to easily connect the sampling tube or bottle to the first outlet during sampling, ensuring smooth flow of the reaction solution, thus simplifying the sampling process and improving work efficiency.

[0034] In some embodiments, a second outlet is formed at the bottom of the housing 221. Thus, by opening the second outlet, it can be ensured that the reaction liquid inside the housing 221 is completely drained, preventing any reaction liquid from remaining inside the housing 221.

[0035] In some embodiments, the sampling element 22 further includes a first valve and a second valve.

[0036] A first valve is located at and connected to the first outlet. A second valve is located between the second outlet and reactor 1, with both ends of the second valve connected to the second outlet and reactor 1 respectively. In a first state, the first valve is open and the second valve is closed; in a second state, the first valve is closed and the second valve is open. Specifically, as follows... Figure 1 As shown, both the first valve and the second valve can be solenoid valves. The first valve is located at the first outlet, and the second valve is located between the second outlet and the reactor 1, with both ends of the second valve connected to the second outlet and the reactor 1 respectively. Thus, the opening and closing of the first outlet and the second outlet are controlled by the first valve and the second valve.

[0037] In some embodiments, the housing 221 is provided with a liquid level observation window that extends vertically to allow observation of the liquid level inside the housing 221. Specifically, the liquid level observation window is made of a high-transparency, corrosion-resistant material, such as tempered glass or plexiglass, ensuring that it will not deform or become blurred during long-term use. The liquid level observation window is embedded in the housing 221 and extends vertically along the housing 221, allowing observation of the reaction liquid level inside the housing 221.

[0038] In some embodiments, the inner circumferential surfaces of both the suction member 21 and the sampling member 22 are coated with an anti-corrosion coating. Specifically, such as Figure 1 As shown, the inner circumferential surfaces of the diaphragm pump 211, the suction pipe 212, and the housing 221 are all provided with anti-corrosion coatings (e.g., epoxy resin, polyurethane, or glass flake coatings). The anti-corrosion coating forms a dense protective film that isolates the inner circumferential surfaces of the suction element 21 and the sampling element 22 from the corrosive reaction liquid, thereby preventing the suction element 21 and the sampling element 22 from being corroded and extending the service life of the equipment.
