Abstract
Description
Technical Field
[0001] This utility model relates to the field of reagent delivery technology in flotation processes, and in particular to a flotation reagent dosing stabilization device. Background Technology
[0002] In flotation processes, the stable addition of reagents is crucial, directly affecting flotation efficiency and mineral processing parameters. However, current flotation reagent addition systems have several shortcomings:
[0003] Unstable dosage: Currently, the method of directly discharging reagents from the large reagent tank is often adopted. As the reagent level in the tank decreases, the static pressure at the outlet of the dosing valve decreases, the reagent flow rate decreases, and the dosage becomes unstable, affecting the stability of the flotation process and the mineral processing indicators.
[0004] Reagent tanks are prone to clogging: Many flotation reagents produce sediment or impurities, forming residue. In existing dosing systems, this residue is difficult to clean in a timely manner and can only be dealt with during equipment shutdown and maintenance. Reagent residue not only occupies tank space but is also easily sucked into the dosing pipes with the reagents, causing pipe blockages, reagent flow interruptions, and other problems. This seriously affects the continuous and stable addition of flotation reagents, reducing beneficiation efficiency and concentrate quality. Utility Model Content

[0024] 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.
[0025] The purpose of this invention is to provide a flotation dosing stabilization device to solve the problems existing in the prior art. It has a simple structure, is easy to use, effectively ensures the stability of the dosing amount, effectively reduces the possibility of residue clogging the dosing pipeline, and effectively improves the stability and reliability of the system.
[0026] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0027] This utility model provides a flotation dosing stabilization device, such as... Figures 1-4As shown, it includes: a large reagent tank 1, a small reagent tank 5, a connecting pipeline 7, and a liquid level stabilization mechanism. The bottom of the large reagent tank 1 is equipped with a slag discharge valve 2; the small reagent tank 5 is equipped with at least one dosing valve 6 for supplying reagents to the flotation equipment; one end of the connecting pipeline 7 is connected to and communicates with the bottom of the side wall of the large reagent tank 1, and the other end is located above the small reagent tank 5 to transport the reagents in the large reagent tank 1 to the small reagent tank 5; the liquid level stabilization mechanism is located inside the small reagent tank 5 and can open or close the outlet of the connecting pipeline 7 to maintain the liquid level in the small reagent tank 5 at a predetermined height. The overall structural design provides a stable reagent supply and liquid level control basis for the flotation dosing process. The large reagent tank 1 serves as the main storage unit for reagents, ensuring sufficient reagent reserves. The small reagent tank 5, in conjunction with the dosing valve 6, can accurately supply reagents to the flotation equipment. The connecting pipeline 7 enables the rational transfer of reagents between the large and small reagent tanks 5. The slag discharge valve 2 can promptly discharge any impurities that may accumulate at the bottom of the large reagent tank 1. The liquid level stabilization mechanism can autonomously adjust the liquid level in the small reagent tank 5 to ensure stable static pressure at the outlet of the dosing valve 6, thereby achieving stable and precise dosing operations, reducing the problem of unstable dosing volume caused by liquid level fluctuations, and improving the stability and reliability of the flotation process.
[0028] In a preferred embodiment, the liquid level stabilizing mechanism includes a float 4 and a valve core assembly. The float 4 floats on the liquid in the small medicine tank 5 and can move up and down with changes in the liquid level in the small medicine tank 5. The valve core assembly is located at the outlet of the connecting pipe 7 to open or close the outlet of the connecting pipe 7 as the float 4 moves up and down. This structure allows the liquid level stabilizing mechanism to automatically control the opening and closing of the connecting pipe 7 according to changes in the liquid level in the small medicine tank 5. The float 4 floats naturally with the liquid level, accurately sensing changes in the liquid level, and through its coordinated work with the valve core assembly, promptly opens or closes the outlet of the connecting pipe 7, ensuring that the liquid level in the small medicine tank 5 is always maintained close to a predetermined height. This effectively improves the automation and accuracy of liquid level control, eliminating the need for frequent manual operation or complex electrical control equipment, thus reducing operational difficulty and cost.
[0029] In a preferred embodiment, the valve core assembly includes a conical valve core 401 and an inner valve seat 701. The conical valve core 401 is fixedly connected to the top of the float 4, and the inner valve seat 701 is disposed within the connecting pipe 7. When the liquid level in the small medicine tank 5 rises to a predetermined height, the float 4 drives the conical valve core 401 to move upward and tightly fit against the inner valve seat 701, thereby sealing the outlet of the connecting pipe 7. The specific combination design of the conical valve core 401 and the inner valve seat 701 improves the sealing effect of the liquid level stabilization mechanism. When the liquid level rises to the set value, driven by the float 4, the conical valve core 401 can accurately and tightly fit against the inner valve seat 701, effectively preventing the medicine from continuing to flow into the small medicine tank 5 and reliably achieving liquid level control. Compared with other structures, this fitting method has better sealing performance and stability, reduces the possibility of medicine leakage, ensures the stability of the liquid level in the small medicine tank 5, and further improves the accuracy and stability of dosing.
[0030] In a preferred embodiment, the inner valve seat 701 is conical or hemispherical. Designing the inner valve seat 701 as conical or hemispherical allows for better mating with the conical valve core 401. The conical or hemispherical surface shape ensures a tighter and more uniform contact between the valve core and the valve seat, accommodating valve core contact at different angles. This enhances the sealing effect and stability, ensuring reliable opening and closing actions whether the valve core is rising to engage or falling to disengage. This further reduces the risk of liquid level runaway due to poor sealing, improving the device's performance and reliability.
[0031] In a preferred embodiment, a guiding mechanism is further included. The bottom end of the guiding mechanism is fixedly connected to the bottom plate of the small medicine tank 5, and the top end of the guiding mechanism is fixedly connected to the float 4. The guiding mechanism can extend or shorten in the vertical direction to constrain the float 4 to move in the vertical direction. The guiding mechanism effectively prevents the float 4 from deviating or shaking due to factors such as liquid sloshing and airflow within the small medicine tank 5. It constrains the float 4 to move only up and down in the vertical direction, ensuring the accuracy and stability of the float 4's movement trajectory. This ensures that the valve core assembly can reliably open or close the outlet of the connecting pipe 7, improving the reliability and accuracy of the liquid level stabilization mechanism in controlling the liquid level, effectively avoiding liquid level control deviations caused by abnormal movement of the float 4, and ensuring the stable operation of the entire dosing system.
[0032] In a preferred embodiment, the guiding mechanism includes a guide rod 402 and a sleeve 501. The sleeve 501 is vertically fixed to the bottom plate of the small medicine box 5. The top end of the guide rod 402 is fixedly connected to the float 4, and the bottom end of the guide rod 402 is inserted into the sleeve 501 and slidably connected to the sleeve 501 in the vertical direction. This specific structural design of the guide rod 402 and the sleeve 501 is clear and practical. The vertically fixed sleeve 501 provides a precise path for the up-and-down sliding of the guide rod 402, ensuring that the guide rod 402 can only move in the vertical direction. The tight connection between the guide rod 402 and the float 4 can accurately constrain the movement of the float 4 in the vertical direction, making the movement of the float 4 more stable and controllable. In long-term use, this simple and effective structure has high durability, can effectively reduce abnormal situations during the movement of the float 4, ensure accurate control of the outlet of the connecting pipe 7, and improve the stability and service life of the device.
[0033] In a preferred embodiment, the connecting pipe 7 includes an integrally connected horizontal pipe and a vertical pipe. The end of the horizontal pipe away from the vertical pipe is connected and communicates with the large medicine tank 1. The vertical pipe is located above the small medicine tank 5, and an inner valve seat 701 is disposed inside the vertical pipe. This design of the connecting pipe 7 facilitates the transfer of medicine between the large and small medicine tanks 5. The horizontal pipe is connected to the bottom of the large medicine tank 1, utilizing gravity to assist the medicine in flowing into the horizontal pipe, and the gentle horizontal pipe helps reduce pressure loss during the medicine flow process. The vertical pipe is located above the small medicine tank 5, facilitating the medicine to flow into the small medicine tank 5 by gravity. At the same time, placing the inner valve seat 701 inside the vertical pipe makes the installation and working environment of the valve core assembly more reasonable, allowing the float 4 to accurately control the opening and closing of the connecting pipe 7 by driving the valve core, ensuring the smoothness of the medicine transfer process and the precision of the control.
[0034] In a preferred embodiment, a reagent valve 3 is also included. The reagent valve 3 is disposed on a horizontal pipe, and the reagent valve 3 disposed on the horizontal pipe allows for manual control of the delivery of reagent from the large reagent tank 1 to the small reagent tank 5. During the initial dosing stage or in special circumstances such as equipment maintenance, opening or closing the reagent valve 3 can effectively control the amount and duration of reagent delivery, increasing the flexibility and controllability of the entire dosing system. Operators can make necessary interventions and adjustments to the reagent injection process according to actual production needs to ensure the normal operation of the system.
[0035] In a preferred embodiment, the bottom of the large medicine tank 1 is a conical structure, and the slag discharge valve 2 is located at the bottom of the conical structure. The conical bottom of the large medicine tank 1 and the placement of the slag discharge valve 2 at the bottom facilitate the natural settling and discharge of the slag. During the use of the large medicine tank 1, impurities and sediments in the medicine will naturally converge to the bottom of the conical shape due to gravity. By opening the slag discharge valve 2, the slag can be smoothly discharged from the large medicine tank 1, reducing the accumulation of slag within the large medicine tank 1, lowering the risk of slag entering the connecting pipeline 7 and the small medicine tank 5, further improving the stability of the dosing system, extending the service life of the equipment, and also reducing equipment failures and maintenance costs caused by slag blockage.
[0036] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
