Description

Technical Field

[0001] This invention relates to the field of mixing device technology, and in particular to a smart water-air vibration anti-sticking mixing device and method for high-concentration tailings mortar. Background Technology

[0002] Currently, in cemented backfill production, there is a trend towards increasingly higher concentrations of backfill mortar. While this brings advantages such as reduced drainage pressure in voids, improved backfill connection, and enhanced strength and safety of the backfill body, it also presents drawbacks, including greater difficulty in mortar preparation. The main issues are poor workability, high mortar consistency, and a tendency for the mortar to stick to mixing equipment. Prolonged sticking can lead to clumping, and these lumps pose a risk of peeling off during mixing. If they fall into the mortar, they can flow into the pipes along with the mortar, becoming one of the main causes of blockages in backfill pipelines.

[0003] In existing technologies, when using water-air vibration to prevent mortar from adhering to the mixing tank wall, the high-pressure water-air impact on the mortar will generate a large amount of foam. The foam will carry solid particles and overflow from installation gaps and other places, which will increase the cleaning burden and may also damage the device. Summary of the Invention

[0004] This invention discloses an intelligent water-air blasting and anti-sticking mixing device and method for high-concentration tailings mortar, which aims to solve the technical problem in the prior art that a large amount of foam is generated during water-air blasting, and the overflowing foam increases the cleaning burden and may also damage the device.

[0005] This invention proposes an intelligent water-air vibration anti-sticking mixing device for high-concentration tailings mortar, comprising a mixing tank body, on which a defoaming module, a scraping module, and a water-air vibration module are provided. The top of the mixing tank body has an installation hole and a circular hole, and a fixed frame is fixedly connected to the top of the mixing tank. A drive motor is fixedly connected to the fixed frame, and a rotating rod is fixedly connected to the output end of the drive motor. The defoaming module includes a working chamber, which is fixedly connected to the installation hole, and a filter screen is fixedly connected to the inner wall of the working chamber. The scraping module includes a movable ring frame, which is movably connected to the circular hole, and a crossbar is fixedly connected to the movable ring frame. A vertical rod is fixedly connected to the end of the crossbar away from the movable ring frame. The water-air vibration module includes an annular tube, which is fixedly connected to the bottom inner wall of the mixing tank body.

[0006] In a preferred embodiment, a general-purpose motor is fixedly connected to the top of the working chamber, and a connecting frame is fixedly connected to the output end of the general-purpose motor. Rotating holes are opened at both ends of the connecting frame, and movable rods are movably connected in both rotating holes. Multiple crushing teeth are fixedly connected to the outside of the two movable rods at equal distances.

[0007] In a preferred embodiment, a gear ring is fixedly connected to the inner wall of the working chamber, and gears are fixedly connected to the outer walls of the two movable rods, with both gears meshing with the gear ring.

[0008] In a preferred embodiment, the defoaming module includes a water inlet pipe, and a diversion pipe is fixedly connected to the top inner wall of the working chamber. The water inlet pipe passes through the working chamber and is fixedly connected to the diversion pipe, and multiple nozzles are equidistantly arranged on the diversion pipe.

[0009] Equipped with a defoaming module, the generated foam is filtered out by a filter screen, carrying away any entrained solids, before entering the working chamber. A universal motor rotates the connecting frame, driving the two gears to rotate in a circular motion. This, in turn, meshes with the gear ring, causing the movable rods on both sides to rotate synchronously. The crushing teeth eliminate the foam, preventing overflow and thus avoiding cleaning burdens and potential damage to the device. The convex center at the bottom of the mixing tank causes the material to flow towards the edges under gravity and mixing action, preventing accumulation and ensuring more thorough mixing at the bottom.

[0010] In a preferred embodiment, multiple sliding members are slidably connected to the outside of both the crossbar and the longitudinal bar. The same bow-shaped spring is fixedly connected to the same side of two adjacent sliding members. Mounting members are fixedly connected to the outside of the multiple bow-shaped springs. Mounting members are provided with mounting grooves. Scrapers are fixedly connected to the mounting grooves. Sliding holes are provided on both the crossbar and the longitudinal bar. Limiting rods are fixedly connected to one side of the multiple mounting members. The multiple limiting rods slide in the corresponding sliding holes.

[0011] In a preferred embodiment, the lower end of the longitudinal rod is movably connected to a rotating component, the rotating component has a movable hole, a rotating shaft is movably connected inside the movable hole, an installation roller and a gear three are fixedly connected to the outside of the rotating shaft, a plurality of scraping teeth are fixedly connected at equal intervals on the outer circumference of the installation roller, and a gear ring three is fixedly connected to the bottom inner wall of the mixing tank body, the gear three and the gear ring three mesh with each other.

[0012] In a preferred embodiment, a second toothed ring is fixedly connected to the outer wall of the movable ring frame, and a servo motor is fixedly connected to the top of the mixing tank body. A second gear is fixedly connected to the output end of the servo motor, and the second gear meshes with the second toothed ring.

[0013] Equipped with a scraping module, the movable ring frame is rotated by a servo motor and gear two meshing, which in turn drives the horizontal and vertical bars to rotate. The scraper blades adhere tightly to the inner wall of the mixing tank body through the elastic action of the bow-shaped spring sheet. As it rotates, it scrapes off the adhering material on the inner wall. Without the use of sliding grooves or other structures, the sliding frame slides directly on the outer wall to avoid blockage. At the same time, the rotating parts rotate with the vertical bar, and through the gear ring three meshing with the gear three, it drives the rotating shaft and the mounting roller to rotate. The scraper teeth scrape and lift the adhering material at the bottom, improving the mixing effect.

[0014] In a preferred embodiment, the water-air vibration module includes a water-air inlet pipe, which passes through the main body of the mixing tank and is fixedly connected to an annular pipe. The annular pipe is provided with multiple inner and outer nozzles at equal intervals around its circumference.

[0015] In a preferred embodiment, the rotating rod is externally fixedly connected to an upper blade and a lower blade, and a discharge pipe is fixedly connected to one side of the mixing tank body, with a valve installed on the discharge pipe.

[0016] By incorporating a water-air vibration module, high-pressure water and air are introduced into the annular pipe through the water-air inlet pipe and then sprayed out through the inner and outer nozzles. The water-air vibration effectively prevents high-concentration mortar from directly contacting the wall surface, reducing the risk of adhesion, and also enhances the fluidity of the mortar and improves the uniformity of mixing.

[0017] A method for intelligent water-air vibration mixing to prevent sticking to walls in high-concentration tailings mortar, using the intelligent water-air vibration mixing device for preventing sticking to walls in high-concentration tailings mortar as described above, includes the following steps:

[0018] Step 1: After the mortar and other materials are poured into the main body of the mixing tank, start the drive motor to drive the upper and lower blades to rotate synchronously, so as to fully mix the mortar. At the same time, high-pressure water vapor is introduced into the annular pipe through the water vapor inlet pipe and sprayed out through the inner and outer nozzles. The water vapor vibration effect effectively prevents the high-concentration mortar from directly contacting the wall surface and enhances the fluidity of the mortar.

[0019] Step 2: Start the servo motor to rotate gear 2. Through the meshing of gear ring 2, the movable ring frame is rotated, which drives the crossbar and vertical bar to rotate. The scraper sticks to the inner wall of the mixing tank body through the elastic action of the bow-shaped spring. As it rotates, it scrapes off the adhering material on the inner wall. At the same time, the rotating part moves with the vertical bar. Through the meshing of gear 3, it drives the rotating shaft and the mounting roller to rotate. The scraper teeth scrape and lift up the adhering material at the bottom.

[0020] Step 3: The generated foam gradually rises and is filtered out by the filter screen, carrying away the solids. It then enters the working chamber. The universal motor is started to rotate the connecting frame, driving the gears on both sides to make circular motion. Through meshing with the gear ring, the moving rods on both sides rotate synchronously, and the foam is eliminated by the breaking teeth.

[0021] As can be seen from the above, the intelligent water-air vibration anti-sticking mixing device for high-concentration tailings mortar provided by the present invention can introduce foam after the solid particles are filtered out by the filter screen into the working chamber. The foam is eliminated by the densely arranged crushing teeth installed in a staggered manner, preventing the overflowing foam from causing a cleaning burden and avoiding damage to the device. Furthermore, the scraping module can scrape off the adhering material on the inner wall of the mixing tank, and at the same time, the scraping teeth scrape and lift the solids at the bottom, improving the mixing effect.

Multiple breaking teeth 711 are fixedly connected to the outside of the two movable rods 708 at equal distances and offsets.

[0034] Reference Figure 1 , Figure 4 and Figure 5 The inner wall of the working chamber 701 is fixedly connected to a gear ring 709, and the outer walls of the two movable rods 708 are fixedly connected to gears 710, and the two gears 710 mesh with the gear ring 709.

The water inlet pipe 705 passes through the working chamber 701 and is fixedly connected to the diversion pipe 704. Multiple nozzles 706 are equidistantly arranged on the circumference of the diversion pipe 704.

[0036] In specific application scenarios, the generated foam is filtered out by the filter screen 702, which removes the entrained solids, and then enters the working chamber 701. The general motor 703 is started to rotate the connecting frame 707, which drives the gears 710 on both sides to make circular motion. Through meshing with the gear ring 709, the movable rods 708 on both sides rotate synchronously. The breaking teeth 711 eliminate the foam, preventing the overflowing foam from causing a cleaning burden and avoiding damage to the device.

[0037] Reference Figure 1 , Figure 6 and Figure 7 Multiple sliding parts 807 are slidably connected to the outside of the horizontal bar 805 and the vertical bar 806. The same bow-shaped spring piece 808 is fixedly connected to the same side of two adjacent sliding parts 807.

Limiting rods 810 are fixedly connected to one side of the multiple mounting parts 809. The multiple limiting rods 810 slide in the corresponding sliding holes.

[0038] Reference Figure 1 , Figure 6 and Figure 7 The lower end of the longitudinal rod 806 is movably connected to a rotating part 812. The rotating part 812 has a movable hole, and a rotating shaft 813 is movably connected in the movable hole. An installation roller 816 and a gear 815 are fixedly connected to the outside of the rotating shaft 813. Multiple scraping teeth 817 are fixedly connected at equal intervals on the outer circumference of the installation roller 816. A gear ring 814 is fixedly connected to the bottom inner wall of the mixing tank body 1. The gear 815 and the gear ring 814 mesh with each other.

[0039] Reference Figure 1 , Figure 6 and Figure 7 A gear ring 804 is fixedly connected to the outer wall of the movable ring frame 803, and a servo motor 801 is fixedly connected to the top of the mixing tank body 1. A gear 802 is fixedly connected to the output end of the servo motor 801, and the gear 802 meshes with the gear ring 804.

[0040] In specific application scenarios, the servo motor 801 rotates the gear 802 to mesh with the movable ring frame 803, which drives the crossbar 805 and the vertical bar 806 to rotate. The scraper 811 adheres tightly to the inner wall of the mixing tank body 1 through the elastic action of the bow-shaped spring 808. As it rotates, it scrapes off the adhering material on the inner wall. At the same time, the rotating part 812 rotates with the vertical bar 806, and through the gear ring 814 meshing with the gear 815, it drives the rotating shaft 813 and the mounting roller 816 to rotate. The scraper teeth 817 scrape and lift the adhering material at the bottom, improving the mixing effect.

[0041] Reference Figure 1 , Figure 2 and Figure 3 The water-air vibration module 9 includes a water-air inlet pipe 902, which passes through the main body 1 of the mixing tank and is fixedly connected to the annular pipe 901. Multiple inner nozzles 903 and outer nozzles 904 are equidistantly arranged on the circumference of the annular pipe 901.

[0042] Reference Figure 1 , Figure 2 and Figure 3 The rotating rod 4 is externally fixedly connected to an upper blade 5 and a lower blade 6, and a discharge pipe 10 is fixedly connected to one side of the mixing tank body 1, with a valve 11 installed on the discharge pipe 10.

[0043] In specific application scenarios, the installation angle of the lower blade 6 is 60 degrees with the vertical direction. High-pressure water and air are introduced into the annular pipe 901 through the water and air inlet pipe 902 and sprayed out through the inner nozzle 903 and the outer nozzle 904. The water and air vibration effect effectively prevents high-concentration mortar from directly contacting the wall surface, reduces the risk of adhesion, and enhances the fluidity of the mortar and improves the uniformity of mixing.

[0044] A method for intelligent water-air vibration mixing to prevent sticking to walls in high-concentration tailings mortar, using the intelligent water-air vibration mixing device for preventing sticking to walls in high-concentration tailings mortar as described above, includes the following steps:

[0045] Step 1: After the mortar is injected into the main body 1 of the mixing tank, start the drive motor 3 to drive the upper blade 5 and the lower blade 6 to rotate synchronously to fully mix the mortar. At the same time, high-pressure water vapor is introduced into the annular pipe 901 through the water vapor inlet pipe 902 and sprayed out through the inner nozzle 903 and the outer nozzle 904. The water vapor vibration effect effectively prevents the high-concentration mortar from directly contacting the wall surface and enhances the fluidity of the mortar.

[0046] Step 2: Start the servo motor 801 to rotate the gear 802. The gear ring 804 meshes with the movable ring frame 803, which drives the crossbar 805 and the vertical bar 806 to rotate. The scraper 811 adheres tightly to the inner wall of the mixing tank body 1 through the elastic action of the bow-shaped spring 808.

[0047] Step 3: The generated foam gradually rises and is filtered out by the filter screen 702, which then enters the working chamber 701. The general motor 703 is started to rotate the connecting frame 707, which drives the gears 710 on both sides to make circular motion. Through the meshing with the gear ring 709, the movable rods 708 on both sides rotate synchronously, and the foam is eliminated by the breaking teeth 711.

[0048] This system employs a neural network algorithm, pre-inputting parameters such as the mortar-to-sand ratio and tailings particle size. Sensors monitor mortar concentration, mixing temperature, and mixing speed in real time, extracting key features from the data, such as mortar fluidity and adhesion tendency. The neural network algorithm, with optimization adjustments to network parameters, then feeds real-time data into the trained neural network for prediction and judgment. Based on the neural network's output, it adjusts water and air pressure and injection volume in real time, and regulates the power of the scraper arm and vibrator to prevent mortar from adhering to the mixing tank walls. This achieves intelligent prediction and control of mortar fluidity and adhesion risk, significantly reducing adhesion risk and promoting the intelligent development of equipment.

[0049] Application of Neural Networks in Intelligent Anti-Adhesion System for High-Concentration Tailings Mortar

[0050] To achieve intelligent prediction and dynamic optimization of the adhesion risk of high-concentration tailings mortar, this invention designs an intelligent control system based on neural networks. This system achieves quantitative prediction of adhesion risk through real-time analysis of multi-dimensional data and provides optimized water-air vibration parameters for dynamically adjusting the device's operating status. The following details its data acquisition, network functions, operating mechanism, and innovative advantages.

[0051] 1. Data Acquisition and Input Mechanism

[0052] The effective operation of neural networks depends on accurate data input. This system designs a complete multi-parameter real-time acquisition system, covering the physical properties of mortar, operating conditions, and environmental factors:

[0053] (1) Mortar physical properties: Concentration C, viscosity V, and cement-sand ratio R are key variables affecting adhesion risk. These data can be continuously monitored using an online ultrasonic concentration meter and a rotational viscometer, and used as the basic input for a neural network.

[0054] (2) Operating parameters: The mixing temperature T, rotation speed Sr, and mortar volume Ms in the bucket are real-time changing operating variables that directly affect the mortar's fluidity and adhesion risk. These data are collected and updated in real time by the corresponding temperature, rotation speed, and weight sensors.

[0055] (3) Environmental factors: Ambient humidity (H) and air temperature (Te) are important external influencing factors. By using high-precision environmental sensors, these data are quantified into model inputs to enhance the network's adaptability to complex environmental changes.

[0056] These data, after preprocessing, are used as input vectors X, and then standardized uniformly: X = [C, V, R, T, Sr, Ms, H, Te]

[0057] The normalization formula is:

[0058] Where Xmin and Xmax are the minimum and maximum values ​​of each parameter, respectively.

[0059] 2. Functions and Architecture of Neural Networks

[0060] The main function of the neural network is to predict the adhesion risk Ra and output the optimal water vapor shock parameters P = [Pw, Pq, F].

[0061] Ra∈[0,1]: represents the adhesion risk score, the higher the value, the greater the adhesion risk;

[0062] Pw: Water vapor injection pressure, unit: kPa;

[0063] Pq: Water vapor jet flow rate, in L / min;

[0064] F: Vibration frequency, measured in Hz.

[0065] Neural network architecture consists of an input layer, hidden layers, and an output layer. It adopts standardized deep learning design logic and has strong adaptability and scalability.

[0066] Input layer: Receives normalized multidimensional input data X

[0067] Hidden layers: Contain several non-linear activation function nodes used to extract complex features. The output of each layer is calculated using the ReLU activation function: h i =ReLU(W i h i-1 +b i )

[0068] Where h i-1 W is the output of the previous layer. i and b i These are the weight matrix and the bias vector, respectively.

[0069] Output layer: consists of two parts:

[0070] 1) Adhesion risk score: R a =s(W risk h L +brisk ), where s(x) is the Sigmoid activation function.

[0071] 2) Optimize parameter output: P = P w ,P q F = ReLU(W params h L +b params )

[0072] 3. Data processing and dynamic adjustment mechanism

[0073] To ensure the model's real-time performance and accuracy, a dynamic data processing and adjustment mechanism was designed. First, after real-time data is input, the network calculates the adhesion risk score under the current conditions through a feature extraction module and compares it with a preset risk threshold. If the score exceeds the threshold, the system immediately triggers an adjustment mechanism, dynamically adjusting the water-air jet pressure, flow rate, and vibration frequency. Furthermore, the system continuously monitors the effects of the adjustments and fine-tunes the model parameters, gradually improving the accuracy of predictions and the effectiveness of control. The specific logic is as follows:

[0074] 1) Adhesion risk detection: Calculate Ra in real time. If Ra > Rthreshold (risk threshold), the adjustment mechanism is triggered.

[0075] 2) Parameter optimization: Based on P = [Pw, Pq, F], dynamically adjust the operating status of the water-air jet and vibration system.

[0076] 3) Feedback Update: The system monitors the effects of the adjustments, re-enters the new data into the network, and uses the optimization results as input for the next cycle.

[0077] Through this mechanism, the network can complete risk prediction and parameter adjustment within milliseconds, ensuring the stability and efficiency of the stirring process.

[0078] 4. Model Training and Optimization

[0079] To improve the model's applicability and generalization ability, the training data for the neural network comes from a wide range of sources, including historical operation records, simulation experimental results, and real-time acquired data. Using supervised learning methods, the model's loss function is defined as the weighted sum of the adhesion risk prediction error and the operational parameter optimization error. During optimization, an adaptive gradient descent algorithm is used to dynamically adjust the weights to quickly converge to the global optimum.

[0080] 5. Network Types and Flexibility

[0081] This invention does not limit the specific type of neural network to ensure the model's versatility and adaptability. The network structure can be adjusted according to actual needs, including but not limited to:

[0082] 1) Multilayer perceptron (MLP): Suitable for processing small-scale, fixed-dimensional data.

[0083] 2) Convolutional Neural Network (CNN): For processing input data with strong spatiotemporal correlation (such as time series or images).

[0084] 3) Recurrent Neural Network (RNN): Suitable for continuous time series prediction.

[0085] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.

6. A method for intelligent water-air vibration anti-sticking mixing of high-concentration tailings mortar, using an intelligent water-air vibration anti-sticking mixing device for high-concentration tailings mortar as described in claim 5, characterized in that... The steps include the following: Step 1: After the mortar is injected into the main body (1) of the mixing tank, the drive motor (3) is started to drive the upper blade (5) and the lower blade (6) to rotate synchronously to fully mix the mortar. At the same time, high-pressure water vapor is introduced into the annular pipe (901) through the water vapor inlet pipe (902) and sprayed out through the inner nozzle (903) and the outer nozzle (904). The water vapor vibration effect effectively prevents the high-concentration mortar from directly contacting the wall surface and enhances the fluidity of the mortar. Step 2: Start the servo motor (801) to rotate gear 2 (802), and rotate the movable ring frame (803) through the meshing of gear ring 2 (804), which drives the crossbar (805) and the vertical bar (806) to rotate. The scraper (811) adheres tightly to the inner wall of the mixing tank body (1) through the elastic action of the bow-shaped spring (808). As it rotates, it scrapes off the adhering material on the inner wall. At the same time, the rotating part (812) moves with the vertical bar (806), and rotates through the meshing of gear 3 (815), which drives the rotating shaft (813) and the mounting roller (816) to rotate. The scraper teeth (817) scrape and lift the adhering material at the bottom. Step 3: The generated foam gradually rises and is filtered out by the filter screen (702) and enters the working chamber (701). The general motor (703) is started to rotate the connecting frame (707), which drives the gears on both sides (710) to make circular motion. Through the meshing with the gear ring (709), the movable rods (708) on both sides rotate synchronously, and the foam is eliminated by the breaking teeth (711).
