Description

Technical Field

[0001] This utility model relates to the field of reflective sheet processing technology, specifically a flotation machine impeller efficiency testing device. Background Technology

[0002] The impeller of the flotation machine is a key component in flotation equipment. It is mainly used for stirring the slurry, shearing and dispersing the gas, and forming bubbles. Its structure usually consists of a disc, blades, and a shaft. Through rotation, air is introduced into the slurry to form a large number of microbubbles, which fully contact the mineral particles, thereby realizing the separation and recovery of minerals.

[0003] The design of the impeller has a significant impact on flotation efficiency, bubble distribution, pulp flow state and energy consumption. Common materials include wear-resistant cast iron, stainless steel and polyurethane. It is suitable for flotation operations of various minerals such as non-ferrous metals, ferrous metals and non-metallic minerals, and is one of the core components for improving flotation performance and saving energy.

[0004] Flotation machine impeller efficiency testing mainly involves parameter acquisition and performance evaluation based on the number of blades and their curvature. By measuring the influence of different structural parameters on the slurry stirring intensity, bubble dispersion degree, and gas-liquid two-phase flow state, the efficiency of the impeller under actual operating conditions can be calculated. Traditional testing devices often use multi-point detection methods for data acquisition. However, due to limitations in the distribution of test points and poor measurement synchronization, there is often a phenomenon of "missed data" where local parameters are not covered, resulting in the loss of key parameters. This affects the accuracy and repeatability of the overall test results, leading to a large error in the final efficiency evaluation results. The data reliability and representativeness are low, making it difficult to fully reflect the true operating performance of the impeller.

[0005] Therefore, a flotation machine impeller efficiency testing device is proposed to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a flotation machine impeller efficiency testing device to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a flotation machine impeller efficiency testing device, including a support base, and further including: a turntable, the turntable being used to insert and place the flotation machine impeller, and the turntable being rotatably mounted on the upper part of the support base; a motor, the motor being fixed on the upper part of the support base; a telescopic rod, the telescopic rod being fixed on one side of the support base; an infrared rangefinder, the infrared rangefinder being fixed on the moving part of the telescopic rod; and a linkage component, the motor synchronously driving the turntable to rotate and the moving part of the telescopic rod to move through the linkage component, thereby realizing the rotation, lifting and scanning action of the flotation machine impeller.

[0008] In the above technical solution, the support base includes a main support base and a secondary support base, the turntable is rotatably mounted on the upper part of the main support base, and the motor is fixedly mounted on the upper part of the secondary support base.

[0009] In the above technical solution, the linkage component includes a gear, which is rotatably installed inside the secondary support and fixedly connected to a gear ring fixed outside the turntable.

[0010] In the above technical solution, the telescopic rod includes a second lead screw rotatably mounted on one side of the main support base. The second lead screw is fixedly connected to a slide rod slidably mounted on one side of the main support base. The infrared rangefinder is fixedly installed inside a fixed seat on the upper part of the slide rod.

[0011] In the above technical solution, a first rotating wheel is fixedly connected to the lower part of the linkage rod fixed to the lower part of the gear, and the first rotating wheel is belt driven by a second rotating wheel fixed to the lower part of the second lead screw; in use, the motor synchronously drives the turntable and the lead screw to rotate.

[0012] In the above technical solution, the upper part of the main support base is provided with a limiting component. The limiting component includes a first lead screw rotatably installed inside the main support base. The outside of the first lead screw is screwed to a tapered rod slidably installed at the center of the main support base. The upper part of the tapered rod is in sliding contact with a limiting plate slidably installed on the upper part of the main support base by a spring. Rotating the first lead screw controls multiple limiting plates to move outward from the center and press against the inner ring of the flotation machine impeller to perform a limiting action.

[0013] In the above technical solution, the tester fixed on one side of the main support is electrically connected to the infrared rangefinder via a cable.

The infrared rangefinder is installed at the moving end of the telescopic rod. Under the coordinated action of the turntable rotation and the telescopic rod lifting, it achieves a spiral scanning trajectory along the surface of the impeller blades, collecting three-dimensional spatial data of each detection point in real time. This structure achieves continuous, blind-zone-free, high-density measurement, effectively avoiding the data omission problem caused by insufficient sampling density in traditional multi-point detection, and improving data integrity and accuracy. The collected data can be further imported into analysis software for three-dimensional modeling and efficiency analysis, providing accurate basis for flotation impeller structure optimization and efficiency evaluation, realizing automated testing, data visualization, and highly repeatable results.

[0020] 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.

[0021] Please see as follows Figures 1-4 The flotation machine impeller efficiency testing device shown includes a support base, and further includes: a turntable for inserting and placing the flotation machine impeller, and the turntable is rotatably mounted on the upper part of the support base; a motor fixed on the upper part of the support base; a telescopic rod fixed on one side of the support base; an infrared rangefinder fixed on the moving part of the telescopic rod; and a linkage component, through which the motor synchronously drives the turntable to rotate and the moving part of the telescopic rod to move, thereby realizing the rotation, lifting and scanning action of the flotation machine impeller.

[0022] The aforementioned flotation machine impeller efficiency testing device integrates a rotation and lifting linkage mechanism to achieve omnidirectional three-dimensional structural scanning of the flotation machine impeller. This allows for efficient and accurate acquisition of key parameters such as the number of impeller blades, curvature distribution, and spatial position, thereby calculating impeller efficiency. During operation, the flotation machine impeller is fixed to a turntable via a plug-in connection. The turntable is mounted on a support base and rotates stably under motor drive. The motor simultaneously drives the turntable rotation and the telescopic rod displacement through a linkage component, ensuring synchronous vertical lifting and lowering of the infrared rangefinder. The infrared rangefinder is mounted on the moving end of the telescopic rod. Under the coordinated action of the turntable rotation and the telescopic rod lifting and lowering, a spiral scanning trajectory is achieved along the impeller blade surface, collecting three-dimensional spatial data from each detection point in real time. This structure achieves continuous, blind-zone-free, high-density measurement, effectively avoiding data omissions caused by insufficient sampling density in traditional multi-point detection, thus improving data integrity and accuracy. The collected data can be further imported into analysis software for three-dimensional modeling and efficiency analysis, providing accurate basis for flotation impeller structure optimization and efficiency evaluation, achieving automated testing, data visualization, and highly repeatable results.

[0023] In this embodiment, the support base includes a main support base and a secondary support base. The turntable is rotatably mounted on the upper part of the main support base, and the motor is fixedly mounted on the upper part of the secondary support base. The linkage component includes a gear, which is rotatably mounted inside the secondary support base and fixedly connected to a gear ring fixed outside the turntable. The telescopic rod includes a second lead screw rotatably mounted on one side of the main support base. The second lead screw is fixedly connected to a slide rod slidably mounted on one side of the main support base. An infrared rangefinder is fixedly mounted inside a fixed base on the upper part of the slide rod. A first rotating wheel is fixedly connected to the lower part of the linkage rod fixed below the gear. The first rotating wheel and the second rotating wheel fixed below the second lead screw are belt driven. In use, the motor synchronously drives the turntable and the lead screw to rotate.

[0024] By dividing the functions of the main support and secondary support, a modular arrangement of the drive system and measurement system is achieved, making the testing process more stable and efficient. Specifically, the flotation machine impeller is installed on the turntable on the upper part of the main support in a plug-in manner, and the turntable can rotate stably under the drive of a motor.

[0025] The motor is fixedly mounted on the secondary support base, and its output shaft is connected to a gear rotatably mounted inside the secondary support base. The gear drives the turntable to rotate by meshing with the external gear ring of the turntable. Simultaneously, a linkage rod is connected to the lower part of the gear, and a first pulley is located at the lower end of the linkage rod. This pulley is belt-driven to a second pulley at the lower part of the second lead screw, thereby driving the second lead screw to rotate synchronously. The second lead screw is the core structure of the telescopic rod, located on one side of the main support base, and connected to a sliding rod that slides vertically. A fixed base is mounted on the upper part of the sliding rod, and an infrared rangefinder is fixedly installed inside the fixed base.

[0026] During the operation of the linkage system, as the motor starts, the turntable begins to rotate at a constant speed, which in turn drives the lead screw to rotate, thereby driving the infrared rangefinder to move up and down synchronously in the vertical direction. This allows the rangefinder to complete a spiral scan along the impeller blade surface. The distance data continuously collected by the infrared rangefinder can be used to construct a three-dimensional contour model, which can then be used for blade number statistics, curvature identification, and efficiency analysis. This linkage structure achieves synchronous control of rotation and lifting, improves measurement continuity and data accuracy, overcomes the problems of sparse detection points and missing data in traditional devices, and provides highly reliable data support for subsequent performance analysis and structural optimization.

[0027] In this embodiment, a limiting component is provided on the upper part of the main support base. The limiting component includes a first lead screw rotatably installed inside the main support base. The outside of the first lead screw is screwed to a tapered rod slidably installed at the center of the main support base. The upper part of the tapered rod is in sliding contact with a limiting plate slidably installed on the upper part of the main support base via a spring. Rotating the first lead screw controls multiple limiting plates to move outward from the center and press against the inner ring of the flotation machine impeller to perform a limiting action. A tester fixed on one side of the main support base is electrically connected to an infrared rangefinder via a cable. The tester receives the electrical signal from the infrared rangefinder and calculates the impeller efficiency, which is displayed on the tester's screen. The tester is also equipped with a start button and a reset button. The motor electrically connected to the tester realizes the forward and reverse rotation of the main shaft through the start button and the reset button.

[0028] Further additions to limit components and test control systems will improve the installation stability and ease of operation of the device.

[0029] The upper part of the main support is provided with a limiting assembly for fixing the flotation machine impeller, including a first lead screw rotatably installed inside the support. The lead screw is screwed to a tapered rod slidably installed at the center of the support. The upper part of the tapered rod slides in contact with multiple limiting plates. The limiting plates are installed on the upper part of the main support by springs and can slide radially.

[0030] By rotating the first lead screw, the cone rod can be driven to move axially, thereby causing the limiting plate to slide along the outer side of the center under the action of spring force and cone surface inclination, gradually pressing against the inner ring of the flotation machine impeller, realizing multi-point limiting positioning, ensuring that the impeller does not deviate or shake during rotation, thus ensuring the stability and repeatability of the measurement;

[0031] In addition, the testing system uses an external tester electrically connected to an infrared rangefinder to receive ranging data in real time and analyze the impeller's structural parameters and operating efficiency through a built-in algorithm. The results can be directly displayed on the screen. The tester is also equipped with start and reset buttons, which can control the motor to perform forward start and reverse reset actions, respectively. That is, after the start button is pressed, the motor drives the turntable and lead screw to run synchronously to complete a complete scanning process; while the reset button is used to terminate the test and return the infrared rangefinder and turntable to their initial positions. This embodiment effectively combines mechanical limit and electronic control to improve testing accuracy, safety and ease of operation, and is suitable for rapid and efficient testing applications of impellers of various specifications.

[0032] The above describes and illustrates the basic principles, main features, and advantages of this utility model.

[0033] Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of this utility model as claimed.
