Description

Technical Field

[0001] The invention belongs to the technical field of mine excavation, in particular to an ion-type rare earth mine injection system. Background Art

[0002] The production of ionic rare earth mines adopts the in-situ leaching process, which requires the leaching agent to be injected into the mountain from the high-level pool through the injection system. The traditional injection system usually includes an injection pipe network, a faucet, a funnel and an injection well.

[0003] At present, the production process of ionic rare earth mines requires workers to monitor the injection blocks continuously for 24 hours. Workers need to adjust the flow of each tap to ensure that the leaching agent does not leak out of the wellhead and achieve the maximum penetration load of each injection well, so as to improve the overall efficiency of the leaching operation.

[0004] With the implementation of "smart mines" in the mining process of ionic rare earth mines, the injection mining work in the mine is gradually moving towards unmanned and digital development. Therefore, an automatic and efficient injection system is needed to replace the mountain-based personnel to complete the injection task, which not only reduces the workload of the mountain-based personnel, but also can more accurately control the leaching agent flow rate of each injection well, saving raw materials. In view of the above problems, an ionic rare earth mine injection system is proposed. Summary of the invention

[0005] In order to make up for the deficiencies of the prior art and solve at least one technical problem raised in the background technology, the present invention proposes an ionic rare earth mine injection system.

[0006] The technical solution adopted by the present invention to solve its technical problem is: an ionic rare earth mine injection system described in the present invention includes a smart mine control system, an injection funnel module, an electromagnetic flowmeter module, a heating module, an electromagnetic sensor module, an electromagnetic valve module and a pressure probe:

[0007] The smart mine control system mainly controls various flow rates and flow rates during the mine injection process, and is responsible for monitoring sudden problems during the mine injection process, and performs injection treatment on the mine by controlling the mine injection device;

[0008] The lower end of the injection funnel module is fixed on the funnel assembly and is responsible for receiving the liquid from the upper injection port;

[0009] The other end of the electromagnetic flowmeter module is connected to the control platform and is responsible for measuring the flow rate and flow velocity of the liquid flowing through the pipeline;

[0010] The heating module is connected to the control platform, which can measure the liquid temperature and set the temperature of the liquid in the heating tube, which can effectively prevent the crystallization of the leaching agent in winter;

[0011] The electromagnetic induction module is controlled by two sets of electrodes. Its working principle is: the height of the electrodes is set, generally at least 30 cm lower than the top of the injection well. When the water level does not submerge the two electrodes, the circuit is in an open circuit state; when the liquid level is higher than the two electrodes, the electrodes are connected to form a path through the liquid conduction. At this time, the electromagnetic sensor sends an electrical signal, and the electromagnetic valve is closed accordingly. That is, the electromagnetic sensor is a liquid level control system to prevent overflow.

[0012] The solenoid valve module is used to control the opening and closing function of the pipeline. Its switch can be controlled by the control platform. When its solenoid valve is closed, the auxiliary pump will also be closed;

[0013] The working principle of the pressure probe module is:

[0014] According to the formula

[0015] P=ρgh

[0016] have to

[0017]

[0018] Where ρ = 1g / cm3, g = 9.8m / s2; The concentration of the general leaching agent is within 10%, so its density is close to the density of water. The coefficient here directly selects the density of water as the conversion standard; In this way, the underwater depth of the probe can be obtained according to the measured pressure, and the electrical signal is transmitted back to the control center in real time. In addition, the liquid level mark can be set. When the liquid level mark is exceeded, the solenoid valve is controlled to stop injecting liquid, and when the liquid level mark is less than a certain liquid level mark, the solenoid valve is controlled to start injecting liquid. It is generally believed that the liquid level should not be less than 30cm from the ground surface.

[0019] Preferably, the smart mine control system includes an auxiliary pump module; the auxiliary pump module is generally used for the leaching agent in the mining field to flow from the high-level pool to the injection well, so the flow rate is slow, and the leaching agent is easy to crystallize in the pipeline, so an auxiliary pump is added to the pipeline to increase the flow rate of the leaching agent, and its rotation speed can be controlled by the control platform.

[0020] Preferably, the method comprises the following steps:

[0021] S1. In actual use, the concentration of the leaching agent is not constant, and it will fluctuate between 10%. The leaching agent solution with a higher concentration is more likely to crystallize and block the pipeline. Therefore, this design reduces the possibility of pipeline blockage by increasing the solution flow rate and raising the solution temperature.

[0022] S2. The general rule of leaching is to first inject a large dose of high-concentration liquid, and then slowly reduce the water volume and the concentration of the leaching agent when the concentration of the leaching agent inside the mountain is close to saturation. After the mountain starts to discharge liquid, the leaching agent will no longer be injected into the mountain, but clean water, called "top water", will be injected to dissolve the rare earth ions that have been exchanged but temporarily retained in the mountain. At this time, the top water can play a cleaning role and dissolve part of the leaching agent crystals accumulated in the pipeline;

[0023] S3. Rare earth ion exchange needs to be carried out in an acidic environment, so the leaching agent is acidic, which is corrosive to pipelines and equipment, so each part will be treated with anti-corrosion;

[0024] S4. Considering that the production cycle of each ionic rare earth ore block is short, the use intensity of related equipment is relatively low. From the perspective of economic benefits, each component needs a higher proper integrity rate to cope with multiple cycles of use;

[0025] S5. Since there is a supporting wall of the injection well to protect and isolate the supporting wall of the injection well, the leakage pipe at the lower end of the injection funnel assembly does not need to be made very long, thus saving some costs.

[0026] Preferably, the mine injection device includes an injection well support wall; a fixed plate is fixedly connected to the top of the injection well support wall; a fixed unit is installed on the top of the fixed plate; a mounting block is installed on the bottom of the fixed plate through the fixed unit; a penetration hole is opened at the end of the injection well support wall; a support rod is fixedly connected to the inner side wall of the injection well support wall; and a funnel bracket is fixedly connected to the end of the support rod.

[0027] Preferably, the fixing unit includes a card slot; the fixing plate and the mounting block are provided with card slots inside; the card slot is slidably connected to a fixing rod inside; the end of the fixing rod is slidably connected to a locking block; the fixing plate is provided with a locking slot inside, and is aligned with the locking block; the fixing rod is slidably connected to a guide block inside; the top of the guide block is fixedly connected to a guide rod; the top of the guide rod is fixedly connected to a guide plate.

[0028] Preferably, the inner side wall of the fixing rod is fixedly connected to a limiting ring; the bottom of the guide plate is hinged to the limiting frame through a torsion spring; a through hole is opened inside the guide plate; a pull rod is slidably connected inside the through hole; a pull plate is fixedly connected to the top of the pull rod; a guide hole is opened at the end of the guide rod; a pull rope is fixedly connected to the bottom of the pull rod, and the pull rope passes through the guide hole, and the other end is fixed to the end of the limiting frame.

[0029] Preferably, a slide groove is provided inside the fixing rod; a slide plate is slidably connected inside the slide groove; a spring is fixedly connected to the end of the slide plate, and the other end of the spring is fixedly connected to the inner wall of the slide groove; a locking block is fixedly connected to the bottom of the slide plate.

[0030] Preferably, the inner side wall of the funnel bracket is fixedly connected to a support frame; the end of the support frame is fixedly connected to a support plate; the top of the support plate is fixedly connected to a support member; the top of the support member is fixedly connected to a motor; the output end of the motor is fixedly connected to a rotating rod, and is rotatably connected to the inside of the support plate; the end of the rotating rod is fixedly connected to a cleaning plate; the end of the locking block is semi-arc-shaped.

[0031] Beneficial effects of the present invention:

[0032] The present invention provides an ionic rare earth mine injection system. After the injection well is drilled by a Luoyang shovel or an impact drill, in order to prevent the well wall from collapsing, the above components need to be plugged into each injection well; they are respectively fixed units, which are driven into the surface to play a fixing role; the fixing plate is mainly attached to the surface of the injection well; the support rod and the funnel bracket are mainly used to support and fix the injection funnel pipe fittings; the fixing plate is designed as a whole with the fixing plate and the funnel bracket, and its length is customized according to the depth of each injection well; the penetration hole is used to penetrate the leaching agent; generally speaking, the injection well passes through the clay layer and the ore body layer and bedrock layers. If the leaching agent penetrates too quickly between different rock layers, it will cause the rock layers to slide against each other and cause landslides. This support component adopts a through-hole design, which not only prevents the inner wall of the injection well from collapsing after being infiltrated, but also reserves enough penetration holes for injection penetration, slowing down the penetration rate and effectively preventing the occurrence of landslides. The penetration holes become more and more sparse from the top to the bottom of the injection well, so that the leaching agent can seep out at the top of the injection well as much as possible. At the same time, the aperture of the penetration hole should not be too small to prevent the high-concentration leaching agent from crystallizing at the hole mouth due to temperature and other reasons and blocking the penetration hole.

[0033] The present invention provides an ion-type rare earth mine injection system. When installing a fixed plate, a mounting block is installed on the top of the mine; then the fixed plate drives the injection well support wall to be inserted into the interior of the mine. During the insertion process, the fixed plate and the mounting block are fitted with each other. Then, a fixing rod is inserted into a card slot. When the insertion is completed, the guide plate is squeezed to drive the guide rod and the guide block to move toward the bottom to squeeze the end of the locking block, so that the locking block is squeezed to slide toward the interior of the locking slot to perform rapid clamping and fixing, thereby further improving the fixing effect between the fixed plate and the mounting block, and improving the supporting and stabilizing effect of the injection well support wall.

The ionic rare earth mine injection system according to claim 1, characterized in that: The smart mine control system includes an auxiliary pump module; the auxiliary pump module generally allows the leaching agent in the mining field to flow from the high-level pool to the injection well, so the flow rate is slow and the leaching agent is easy to crystallize in the pipeline, so an auxiliary pump is added to the pipeline to increase the flow rate of the leaching agent, and its rotation speed can be controlled by the control platform.

3. The ionic rare earth mine injection system according to claim 1, characterized in that: The following steps are involved: S1. In actual use, the concentration of the leaching agent is not constant, and it will fluctuate between 10%. The leaching agent solution with a higher concentration is more likely to crystallize and block the pipeline. Therefore, this design reduces the possibility of pipeline blockage by increasing the solution flow rate and raising the solution temperature. S2. The general rule of leaching is to first inject a large dose of high-concentration liquid, and then slowly reduce the water volume and the concentration of the leaching agent when the concentration of the leaching agent inside the mountain is close to saturation. After the mountain starts to discharge liquid, the leaching agent will no longer be injected into the mountain, but clean water, called "top water", will be injected to dissolve the rare earth ions that have been exchanged but temporarily retained in the mountain. At this time, the top water can play a cleaning role and dissolve part of the leaching agent crystals accumulated in the pipeline; S3. Rare earth ion exchange needs to be carried out in an acidic environment, so the leaching agent is acidic, which is corrosive to pipelines and equipment, so each part will be treated with anti-corrosion; S4. Considering that the production cycle of each ionic rare earth ore block is short, the use intensity of related equipment is relatively low. From the perspective of economic benefits, each component needs a higher proper integrity rate to cope with multiple cycles of use; S5. Since there is a supporting wall of the injection well to protect and isolate the supporting wall of the injection well, the leakage pipe at the lower end of the injection funnel assembly does not need to be made very long, thus saving some costs.
