Description

Technical Field

[0001] The utility model relates to the technical field of medicine mixing devices, in particular to a medicine mixing device for a spray system. Background Art

[0002] In the heap leaching process, after the gold-bearing ore is piled up, it is necessary to spray the ore with a leaching agent so that the gold in the ore reacts with the agent and enters the solution to form a precious liquid. Before spraying the ore, according to the spraying system and requirements of the ore, a spray liquid with a certain concentration of agent needs to be prepared in the spray pool for use during spraying.

[0003] Existing sprinkler system Figure 1 As shown, when dispensing, the solid agent is directly added to the spray pool 2 to dissolve for dispensing. After dispensing, the spray liquid is sent to the ore pile 1 along the spray pipe 4 through the delivery pump 3 for spraying. Since the spray pool 2 in this system is relatively large, with a diameter of about 20 meters, and there is no stirring device, each time 300-600m³ of spray liquid is prepared, the solid agent is directly added to the spray pool filled with water. The solid agent can only be dispersed by its own solubility, and the agent dissolution and dispersion effect is poor. It is difficult to disperse evenly in the pool. The agent concentration is high at the dosing point, and the agent concentration is low at a distance from the dosing point. Such agent concentration cannot meet the requirements of ore pile spraying.

[0004] Generally, the height of the ore pile can reach 10-12 meters. When the spray liquid is sprayed on the surface of the ore pile, the spray liquid penetrates from the surface of the ore pile to the inside, thereby leaching the ore. If different concentrations of reagents are sprayed, high concentration reagents cannot correspondingly increase the ore leaching rate. On the contrary, too high concentration will have a certain inhibitory effect, resulting in a waste of reagents; low concentration reagents will become lower and lower in the penetration process, thereby reducing the ore leaching speed and leaching rate. Utility Model Content

[0005] In view of the above problems, the utility model provides a spray system reagent mixing device, which mainly solves the problem that uneven configuration of spray reagents in a heap leaching workshop affects ore leaching.

[0006] The specific technical scheme of the utility model is: a spray system medicine mixing device, including a spray pool, a dissolving medicine pool is installed on the top of the spray pool, the side outlet of the dissolving medicine pool is connected with the top opening of the spray pool, a water inlet pipe is installed at the top opening of the dissolving medicine pool, and a screen is installed at the side outlet of the dissolving medicine pool.

[0007] Furthermore, preferably, at least two spray systems are symmetrically installed on the horizontal line of the center of the top opening of the spray pool, and the spray system includes a spray pipe connecting the spray pool with the ore pile and a delivery pump installed on the spray pipe. The spray pipe at the outlet end of the delivery pump is also connected to a return pipe, and the other end of the return pipe extends into the spray pool along the inner wall of the spray pool, and the outlets of the two symmetrically arranged return pipes are tangentially arranged counterclockwise or clockwise, and valve one is installed on the return pipe, and valve two is installed on the spray pipe away from the return pipe.

[0008] Furthermore, preferably, the outlet of the water return pipe extends into the spray pool to a height of 1 / 2-1 / 4.

[0009] The beneficial effect of the utility model is that the device is provided with an independent drug dissolving pool, which can pre-mix and dissolve the solid drug with water, and then introduce the mixed liquid into the spray pool by gravity, so that the dissolved drug can be dispersed in the water first, which is conducive to the mixing of the drug. At the same time, with the return pipe circulation system with circulation mixing and stirring functions, the drug mixture at multiple points is circulated and stirred, so that the drug is fully dispersed and mixed, ensuring that the concentration of the prepared drug is uniform and meets the standard, thereby improving the leaching speed and leaching rate of the ore inside and at the bottom of the ore pile.

[0014] In order to make the technical problems and technical solutions solved by the utility model more clearly understood, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0015] In the description of the present invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0016] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0017] like Figure 2 As shown, a spray system reagent mixing device includes a spray pool 2, a dissolving medicine pool 8 is installed on the top of the spray pool 2, the dissolving medicine pool can be square, round or other irregular shapes, and can be welded with steel plates, the side outlet of the dissolving medicine pool 8 is connected with the top opening of the spray pool 2, a water inlet pipe 9 is installed at the top opening of the dissolving medicine pool 8 (the water inlet pipe can adopt the existing spray pool water inlet pipe), and a screen 10 is installed at the side outlet of the dissolving medicine pool 8.

[0018] When preparing the spray agent, first pour the solid agent into the dissolving pool 8, open the water inlet pipe, allow the water and the agent to be preliminarily mixed and dissolved, and dissolve while adding water, which is more conducive to the dissolution and dispersion of the agent. The mixed liquid then flows into the spray pool 2 through the screen 10. Since the screen 10 plays a certain blocking role, it can slow down the flow rate of the mixed liquid, prolong the mixing and dissolution time of the agent and water, and is conducive to the uniform dispersion of the agent.

[0019] like Figure 2 As shown, in order to make the reagent entering the spray pool more evenly dispersed, at least two spray systems are symmetrically installed on the horizontal center line of the top opening of the spray pool 2 (that is, two groups of 1 are symmetrically installed, or multiple groups can be symmetrically installed, and the specific number is determined according to the reagent mixing effect. Of course, 3 or 5 spray systems can also be arranged in a circular array to achieve the same technical effect). The spray system includes a spray pipe 4 that connects the spray pool 2 with the ore pile 1 and a delivery pump 3 installed on the spray pipe 4. The spray pipe 4 at the outlet end of the delivery pump 3 is also connected to a return pipe 5. The other end of the return pipe 5 extends into the spray pool 2 along the inner wall of the spray pool 2, and the outlets of the two symmetrically arranged return pipes 5 are tangentially arranged counterclockwise or clockwise (such as Figure 3As shown), a valve 1 6 is installed on the return pipe 5, and a valve 2 7 is installed on the spray pipe 4 away from the return pipe 5. Of course, while achieving the same technical effect, a three-way valve can also be installed at the junction of the return pipe 4 and the spray pipe 4 to control the flow direction of the agent.

[0020] When the liquid level of the mixed liquid of the reagents entering the spray pool is higher than the outlet of the return pipe, open valve 16 and start the delivery pump 3. The delivery pump 3 will extract the mixed liquid from the spray pool 2 and return it to the spray pool 2 through the return pipe 5. This cycle repeats to mix the reagents in the pool. The structure of the mechanism is symmetrically arranged on the center line, which can expand the area of ​​​​circulation and mixing relative to other adjacent positions; at the same time, the tangential counterclockwise or clockwise arrangement of the outlets of the two symmetrically arranged return pipes can cause the mixed liquid in the spray pool to rotate counterclockwise or clockwise under the impact of the outlet mixed liquid, which plays a stirring role and is more conducive to the dispersion and mixing of the reagents.

[0021] Further preferably, the outlet of the return pipe 5 extends into the spray pool 2 at a height of 1 / 2-1 / 4, so that the circulation system of the return pipe 5 can function as early as possible and can also play a stirring role when a large amount of mixed liquid enters.

[0022] The present invention is described in detail above through specific and preferred embodiments, but those skilled in the art should understand that the present invention is not limited to the embodiments described above, and any modifications, equivalent substitutions, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
