Description

Technical Field

[0001] This utility model relates to the technical field of thickener auxiliary equipment, specifically a thickener feed well with a self-dilution amount control mechanism. Background Technology

[0002] Thickeners are solid-liquid separation equipment widely used in industries such as metallurgy, chemical industry, coal, mineral processing, and environmental protection. They use the principle of natural sedimentation to separate liquids and solids in slurry. The core structure that affects the separation effect is the feed well of the thickener. As a key component of the thickener, the performance of the feed well directly affects the working efficiency and concentration effect of the thickener.

[0003] However, the existing thickener feed well still has some problems:

[0004] In existing thickener feed wells, it is often difficult to accurately and automatically control the amount of dilution water according to the actual concentration and flow rate of the slurry during the feeding process. When the slurry concentration is too high, if the amount of dilution water is insufficient, the slurry will have poor flowability in the feed well, which will easily cause blockage and affect subsequent thickening operations. On the other hand, when the slurry concentration is low, if the amount of dilution water is too high, it will waste water resources, increase production costs, and may also affect the normal operating parameters of the thickener.

[0005] Therefore, we propose a thickener feed well with a self-dilution rate control mechanism to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this invention is to provide a thickener feed well with a self-dilution control mechanism to solve the problems mentioned in the background art, where the thickener feed well often struggles to accurately and automatically control the dilution water volume according to the actual concentration and flow rate of the slurry during the feeding process. When the slurry concentration is too high, insufficient dilution water will result in poor slurry flow within the feed well, easily causing blockages and affecting subsequent thickening operations. Conversely, when the slurry concentration is low, excessive dilution water will waste water resources, increase production costs, and may also affect the normal operating parameters of the thickener.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a thickener feed well with a self-dilution amount control mechanism, comprising a feed well body and a dilution water storage tank:

[0008] A dilution water storage tank is provided on one side of the main body of the feeding well. A water pump is bolted to the upper end of the dilution water storage tank. A main pipeline is connected to one side of the water pump, and the end of the main pipeline extends into the interior of the dilution water storage tank. A branch pipeline is connected to the other side of the water pump. Three annular pipes are fixedly installed on the upper section of the main body of the feeding well. A guide pipe is connected to the middle of the annular pipe. A smart control valve is connected to one end of the guide pipe by a flange. A connecting pipe is connected to the other end of the smart control valve by a flange. A dilution water pipeline connected to the connecting pipe is provided on the inner wall of the main body of the feeding well. Several nozzles are connected to the outer surface of the dilution water pipeline. A fixing clamp is nested on the outer surface of the dilution water pipeline.

[0009] Using the above technical solution, the water pump draws water from the dilution water storage tank through the main pipeline, and then distributes the water through the branch pipeline to the annular pipe on the upper part of the feed well body. The water then enters the dilution water pipeline through the guide pipe, intelligent control valve and connecting pipe, and is finally sprayed out by the nozzle. This realizes the delivery of water in the dilution water storage tank to the feed well body as needed. The intelligent control valve precisely controls the dilution water flow rate, and the uniform spraying through the nozzle achieves the dilution of the slurry to meet the working requirements of the thickener.

[0010] Preferably, the fixing clamp is fixed at the connection between the dilution water pipeline and the connecting pipe, and the end of the fixing clamp is welded to the main body of the feeding well.

[0011] The above technical solution involves fixing the clamp at the connection between the dilution water pipeline and the connecting pipe, with its end welded to the main body of the feeding well. This stabilizes the connection structure, enhances the stability of the connection between the dilution water pipeline and the connecting pipe, and prevents loosening or detachment under water flow impact and equipment vibration, thus ensuring the reliability and continuity of the dilution water transportation process.

[0012] Preferably, the branch pipeline is divided into three branches, and the annular pipe and the branch pipeline are connected in a one-to-one correspondence, and the guide pipe and the annular pipe are connected in a one-to-one correspondence, and the three dilution water pipelines are arranged vertically along the inside of the feed well body.

[0013] Using the above technical solution, the branch pipeline is divided into three, each corresponding to a ring pipe. Each ring pipe is then connected to a guide pipe. The three dilution water pipelines are arranged vertically inside the main body of the feed well, so that the dilution water is evenly distributed from the branch pipelines to the ring pipes, and then enters the dilution water pipelines at different locations through the guide pipes. This allows for comprehensive and uniform dilution of the slurry at different heights within the main body of the feed well, thereby improving the dilution effect.

[0014] Preferably, a base frame is welded to one side of the main body of the feeding well, a slurry inlet pipe is welded to the upper end of the base frame, a feeding hopper is welded to the upper end of the slurry inlet pipe, and the feeding hopper is funnel-shaped with the opening of the feeding hopper decreasing from top to bottom.

[0015] Using the above technical solution, the main body of the feeding well is supported by a base frame, and the slurry inlet pipe is welded to the base frame. The slurry enters the slurry inlet pipe from the funnel-shaped feed hopper with a decreasing opening from top to bottom. The base frame provides stable support for the slurry inlet pipe. The funnel-shaped feed hopper with a decreasing opening facilitates the introduction of slurry into the slurry inlet pipe and can slow down the slurry flow rate to a certain extent, which is conducive to the uniform entry of the slurry into the main body of the feeding well.

[0016] Preferably, a motor is bolted to one side of the slurry inlet pipe, and a drive shaft is rotatably connected to the output end of the motor and located in the middle of the slurry inlet pipe. A spiral guide vane is fixed on the outer surface of the drive shaft, and a discharge port is opened on the other side of the slurry inlet pipe.

[0017] Using the above technical solution, after the motor starts, it drives the drive shaft to rotate in the middle of the slurry inlet pipe. The spiral guide vanes on the drive shaft rotate accordingly, causing the slurry to form a spiral flow in the slurry inlet pipe, promoting uniform mixing of the slurry, and smoothly guiding the slurry to the discharge port, preparing it for entering the main body of the feeding well.

[0018] Preferably, a fixed frame is welded to the outlet end of the slurry inlet pipe, a sliding groove is provided on the inner side of the fixed frame, an electric push rod is bolted to the top of the fixed frame, a gate is fixed to the extended end of the electric push rod, and sliding rods corresponding to the sliding groove are welded to both sides of the gate.

[0019] By adopting the above technical solution, the electric push rod can precisely adjust the opening of the slurry inlet pipe outlet by controlling the raising and lowering of the gate, thereby flexibly controlling the flow rate of slurry into the main body of the feeding well and ensuring that the feeding process is stable and controllable.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] 1. The water pump draws water from the dilution water storage tank and distributes it through the main pipeline and branch pipelines to three ring pipes. Then, through the guide pipe, intelligent control valve, and connecting pipe, the water flows into the three dilution water pipelines arranged vertically inside the main body of the feed well. Finally, the water is sprayed out through the nozzle, which ensures that the dilution water is evenly distributed within the main body of the feed well, achieving comprehensive and sufficient dilution of the slurry. At the same time, the intelligent control valve can precisely control the dilution water flow rate to adapt to the dilution requirements of slurries of different concentrations, ensuring that the slurry is at the appropriate concentration, and providing a strong guarantee for the efficient operation of the thickener.

[0022] 2. The fixing clamp is fixed at the connection between the dilution water pipeline and the connecting pipe and welded to the main body of the feed well, which enhances the stability of the pipeline connection and can effectively prevent problems such as loosening and falling off during water flow impact and equipment operation. This ensures the reliability and continuity of the dilution water transportation process, reduces equipment failure and maintenance costs, and improves the service life and working efficiency of the entire thickener feed well.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0030] Please see Figures 1-5This utility model provides a technical solution: a thickener feed well with a self-dilution amount control mechanism, including a feed well body 1 and a dilution water storage tank 14. A dilution water storage tank 14 is provided on one side of the feed well body 1. A water pump 15 is bolted to the upper end of the dilution water storage tank 14. A main pipeline 16 is connected to one side of the water pump 15, and the end of the main pipeline 16 extends into the interior of the dilution water storage tank 14. A branch pipeline 17 is connected to the other side of the water pump 15. Three annular pipes 18 are fixedly installed on the upper section of the feed well body 1. A guide pipe 19 is connected to the middle of the annular pipes 18. A smart control valve 20 is connected to one end of the guide pipe 19 by a flange. A connecting pipe 21 is connected to the other end of the smart control valve 20 by a flange. A dilution water pipeline 22 is provided on the inner wall of the feed well body 1 and is connected to the connecting pipe 21. Several nozzles 23 are connected to the outer surface of the dilution water pipeline 22. A fixing clamp 24 is nested on the outer surface of the dilution water pipeline 22. The fixing clamp 24 is fixed at the connection between the dilution water pipeline 22 and the connecting pipe 21, and the end of the fixing clamp 24 is welded to the main body 1 of the feeding well. The branch pipeline 17 is divided into three branches, and the ring pipe 18 is connected to the branch pipeline 17 in a one-to-one correspondence, and the guide pipe 19 is connected to the ring pipe 18 in a one-to-one correspondence, and the three branches of the dilution water pipeline 22 are arranged vertically along the inside of the main body 1 of the feeding well.

[0031] Pump 15 draws dilution water from dilution water storage tank 14 through main pipeline 16, and distributes the water through branch pipeline 17 to three corresponding annular pipes 18 on the upper section of the feed well body 1. The water in the annular pipes 18 flows through guide pipe 19, intelligent control valve 20 and connecting pipe 21 into the three vertically arranged dilution water pipelines 22 in the feed well body 1, and is finally sprayed out by nozzles 23 on the dilution water pipelines 22. Fixing clamp 24 is fixed at the connection between the dilution water pipelines 22 and the connecting pipe 21 and welded to the feed well body 1 to provide stability. The intelligent control valve 20 can then precisely control the dilution water flow rate. The vertically distributed dilution water pipelines 22 and nozzles 23 are used to comprehensively and uniformly dilute the slurry entering the feed well body 1. At the same time, fixing clamp 24 ensures the stability of the pipeline connection, ensuring that the entire dilution process is reliable and efficient, preventing blockage during flow, meeting the slurry concentration requirements of the thickener, and avoiding water waste.

[0032] A base frame 2 is welded to one side of the main body 1 of the feeding well. A slurry inlet pipe 3 is welded to the upper end of the base frame 2. A feed hopper 4 is welded to the upper end of the slurry inlet pipe 3. The feed hopper 4 is funnel-shaped, and the opening of the feed hopper 4 decreases from top to bottom. A motor 5 is bolted to one side of the slurry inlet pipe 3. A drive shaft 6 is rotatably connected to the output end of the motor 5, located in the middle of the slurry inlet pipe 3. Spiral guide vanes 7 are fixed to the outer surface of the drive shaft 6. A discharge port 8 is opened on the other side of the slurry inlet pipe 3. A fixing frame 9 is welded to the outlet end of the slurry inlet pipe 3. A sliding groove 10 is opened on the inner side of the fixing frame 9. An electric push rod 11 is bolted to the top of the fixing frame 9. A gate 12 is fixed to the extended end of the electric push rod 11. Sliding rods 13, which are slidably connected to the sliding groove 10, are welded to both sides of the gate 12.

[0033] The main body 1 of the feed well is supported by the base frame 2. The feed pipe 3 is welded to the base frame 2 on one side. The upper end of the feed pipe 3 is welded with a funnel-shaped feed hopper 4 with the opening decreasing from top to bottom, which facilitates the introduction of slurry and slows down the flow rate. The motor 5 is installed on one side of the feed pipe 3. After starting, it drives the drive shaft 6 and the spiral guide vanes 7 fixed on its outer surface to rotate in the middle of the feed pipe 3, which promotes the uniform mixing of slurry and guides it to the discharge port 8. The inner side of the fixed frame 9 at the outlet end of the feed pipe 3 is provided with a groove 10. The electric push rod 11, which is bolted to the top, has a gate 12 with a sliding rod 13 fixed at its extended end. The sliding rod 13 slides in the groove 10, thereby accurately controlling the opening of the outlet of the feed pipe 3. This enables the introduction, mixing and transportation of slurry to the flow rate control, so as to stably and high-qualityly transport slurry to the main body 1 of the feed well and lay the foundation for the subsequent dilution and thickening machine operation.

[0034] Working principle: For this type of thickener feed well with a self-dilution rate control mechanism, the slurry enters the feed pipe 3 through the funnel-shaped feed hopper 4 with a decreasing opening. The motor 5 drives the drive shaft 6 and the spiral guide vanes 7 to rotate, causing the slurry to mix and flow towards the discharge port 8. At the same time, the electric push rod 11 precisely adjusts the opening of the feed pipe 3 outlet by controlling the sliding of the gate 12 in the chute 10, thereby controlling the slurry flow rate. Simultaneously, the water pump 15 draws dilution water from the dilution water storage tank 14 and discharges it through the main pipe. The slurry enters the branch pipe 17 through the 16th channel, and is diverted to the three annular pipes 18 on the upper section of the main body 1 of the feed well. Then, it flows through the guide pipe 19, the intelligent control valve 20, and the connecting pipe 21 into the three dilution water pipes 22 arranged vertically inside the feed well. Finally, it is sprayed out by the nozzle 23, which realizes the comprehensive and uniform dilution of the slurry entering the main body 1 of the feed well. The fixed clamp 24 stabilizes the connection between the dilution water pipe 22 and the connecting pipe 21, ensuring the reliable operation of the whole process and providing slurry of suitable concentration for the thickener.
