Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of slag recycling, and particularly relates to a slag resource recycling and cleaning device. BACKGROUND

[0002] As one of the main solid wastes generated in the industrial production process, the resource recycling and utilization of slag is an important measure to realize the green and circular development of industry, which can not only reduce the occupation and pollution of the environment caused by waste storage, but also convert the slag into building material raw materials, metal extraction substrates and other useful resources, thereby achieving significant economic and environmental benefits. In the whole process of slag resource recycling and utilization, cleaning treatment is a core pre-link, which needs to effectively remove dust, soil, harmful chemical residues and fine impurities attached to the surface of the slag to ensure the product quality of the subsequent processing link. At present, the mainstream slag cleaning equipment in the industry mainly adopts a rotating cleaning structure, which drives the cleaning cylinder to rotate through an external driving device, so that the slag rolls in the cylinder with the cleaning cylinder, and the surface impurities are preliminarily removed by the physical friction between the slag particles. At the same time, a fixed flushing assembly is arranged to spray water flow to assist cleaning. The sewage and fine impurities generated in the cleaning process are discharged through the screen on the cleaning cylinder, and the basic cleaning of the slag is completed.

[0003] The existing slag resource recycling and cleaning device lacks effective regulation of the rolling track of the slag in the rotating cleaning cylinder, and the slag in the dense area is prone to local accumulation and sparse distribution. The slag in the dense area is blocked by each other, resulting in a cleaning blind area. The sparse area is subjected to excessive water flushing, causing waste of water resources and energy. In addition, the fixed flushing assembly cannot adjust the spraying angle and distance according to the scattering state of the slag, and there are problems of incomplete flushing coverage and mismatched cleaning strength. Therefore, in view of the above status, it is urgent to develop a slag resource recycling and cleaning device to overcome the deficiencies in the current actual application. SUMMARY

Detailed Implementation

[0061] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0062] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0063] Please see Figures 1-11 The present invention provides a slag resource recycling and cleaning device, including a cleaning shaft 1, which is connected to an external drive support structure, and further comprising:

[0064] A rotating cleaning cylinder 2 is fixedly installed on the cleaning shaft 1. An external drive support structure drives the cleaning shaft 1 and the rotating cleaning cylinder 2 to rotate, which is used to perform rolling rinsing and cleaning of slag raw materials.

[0065] An adjustment port 14 is provided on the rotary washing cylinder 2, and a retention adjustment mechanism is also provided at the adjustment port 14. The retention adjustment mechanism is connected to the rotary washing cylinder 2 and is used to adjust the rolling position of the slag raw material in the rotary washing cylinder 2.

[0066] The retention adjustment mechanism is also equipped with an adjustable flushing device for cleaning the slag raw materials in a scattered state.

[0067] The system includes a control and detection system, which is connected to the retention adjustment mechanism, the adjustable flushing equipment, and the external drive support structure. The control and detection system is used to control the rotation speed of the rotating washing cylinder 2 and the flushing parameters of the adjustable flushing equipment according to the rolling and scattering state of the slag raw materials.

[0068] Please see Figures 1-3 The rotating cleaning cylinder 2 has cleaning screens 3 distributed on its circumference, and the cleaning screens 3 are detachably connected to the rotating cleaning cylinder 2.

[0069] Furthermore, the rotating washing cylinder 2 is also provided with multiple reinforcing steel plates 5, which are fixedly connected to the cleaning screen 3; wherein, the cleaning screen 3 is also provided with a material inlet 4 for the slag raw material to enter and exit the rotating washing cylinder 2.

[0070] In the field of slag resource recycling and cleaning, existing equipment generally suffers from problems such as uneven rolling of slag in the washing drum leading to insufficient cleaning, screens being easily deformed and detached by slag impact, and difficulty in adapting to the cleaning needs of slag with different particle sizes. This invention uses an external drive support structure (adopting a drive form combining a motor and a gearbox to ensure stable output speed and sufficient torque to meet the drive requirements of slag with different weights) to drive the cleaning shaft 1 to rotate on the support frame, and the cleaning shaft 1 in turn drives the rotating washing drum 2 fixed on it to rotate synchronously.

[0071] Under normal cleaning conditions (with the retention adjustment mechanism and control detection system in a non-working state, and the slag raw material rolling and cleaning normally inside the rotary cleaning drum 2), the slag raw material enters the rotary cleaning drum 2 through the feed inlet 4 on the cleaning screen 3 (made of 304 stainless steel, with mesh size selectable according to slag particle size to avoid slag jamming or residue of fine impurities). During the rotation of the rotary cleaning drum 2, the slag rolls irregularly inside the drum, achieving physical friction cleaning between the slag particles. At the same time, the cleaning screen 3 can promptly discharge the wastewater, dust, and fine impurities generated during cleaning, avoiding secondary pollution. The reinforcing steel plate 5 (which can be fixed to the inner wall of the rotary cleaning drum 2 and the edge of the cleaning screen 3 through welding) forms a rigid support for the cleaning screen 3, preventing it from deforming or detaching from the rotary cleaning drum 2 under long-term impact from the slag, thus extending the service life of the equipment.

[0072] Depending on the cleaning situation and the degree of contamination of the slag raw material, the retention adjustment mechanism can be activated either during the operation of the rotary washing drum 2 or before cleaning the slag raw material. After the retention adjustment mechanism is activated, as the rotary washing drum 2 rotates, the slag raw material reaching the retention adjustment mechanism is first blocked (it will not roll to the bottom of the rotary washing drum 2 under its own gravity). When it is lifted to a certain height, it falls to the lowest point of the rotary washing drum 2 under its own gravity. During this falling process, the control and detection system monitors the process. The system collects data on the density and velocity of slag within the rotary washing drum 2. When dense localized slag distribution is detected, the system can control the retention adjustment mechanism to adjust the slag distribution and reduce the rotation speed of the rotary washing drum 2. Simultaneously, it regulates the water pressure and flow rate of the adjustable washing equipment to ensure that the slag material can fully contact the washing water during the scattering process. This solves the problem of localized overwashing and unwashed areas in existing equipment. The detachable connection between the cleaning screen 3 and the rotary washing drum 2 (using bolt connection) facilitates the replacement of screens with different mesh sizes according to slag processing needs, improving the equipment's versatility.

[0073] In one embodiment of the present invention, please refer to Figures 1-11 The retention adjustment mechanism includes:

[0074] A slag retention frame 16 is provided, one end of which is rotatably connected to the inner wall of the rotating washing cylinder 2 via an adjustable corner part 17. A vibrating filter screen 18 can also be detachably installed on the slag retention frame 16.

[0075] The length and width of the slag retention frame 16 are both greater than the length and width of the adjustment port 14;

[0076] And an angle adjustment drive assembly, which is connected to the rotating cleaning cylinder 2 and the slag retention frame 16 respectively, and is used to drive the slag retention frame 16 to rotate around the adjusting angle part 17.

[0077] The angle adjustment drive component includes:

[0078] A protective baffle 6 is fixedly installed on the rotating cleaning cylinder 2 and is located near the adjustment port 14. A supporting main rod 13 is also fixedly installed on the protective baffle 6.

[0079] Both ends of the main support rod 13 are rotatably mounted with adjusting connecting rods 2 12, and the other ends of the two adjusting connecting rods 2 12 are rotatably mounted with adjusting connecting rods 1 9. The other end of the adjusting connecting rods 1 9 is rotatably connected to the slag retention frame 16 through a hinged mounting seat 15.

[0080] And a driving force rod 10, the two ends of which are fixedly connected to the two adjusting connecting rods 9 respectively, wherein a hydraulic system 11 is provided between the driving force rod 10 and the supporting main rod 13;

[0081] The hydraulic system 11 drives the slag retention frame 16 to rotate around the adjusting corner section 17 by adjusting the included angle between the adjusting connecting rod 19 and the adjusting connecting rod 212.

[0082] The other end of the slag retention frame 16 is provided with a fitting arc surface 19, which fits against the inner wall of the rotating cleaning cylinder 2 under normal working conditions.

[0083] The present invention achieves dynamic control through the following structural cooperation: When the slag rolls to the adjustment port 14 in the rotating washing cylinder 2, in the initial state (i.e., the working state of normal cleaning), the slag retaining frame 16 (made of high manganese steel wear-resistant material, with anti-corrosion surface treatment to adapt to the wear of slag and the corrosion of washing water) is rotatably connected to the inner wall of the rotating washing cylinder 2 through the adjustment corner part 17 (built-in deep groove ball bearing to reduce the coefficient of rotational friction and ensure smooth adjustment). The fitting arc surface 19 at the other end (adopting an arc structure design, consistent with the curvature of the inner wall of the rotating washing cylinder 2) is tightly fitted to the cylinder wall to form a closed state, preventing the slag from leaking out from the adjustment port 14. At this time, as the rotating washing cylinder 2 rotates, the slag raw material continues to roll in the rotating washing cylinder 2, and the normal cleaning operation is achieved through the setting of the conventional fixed water spray head (not shown in the figure).

[0084] The protective baffle 6 (made of bent steel plate, welded to the outer wall of the rotating cleaning cylinder 2 and located near the adjustment port 14) protects the retention adjustment mechanism during rotation. Simultaneously, the support rod 13 (made of solid round steel to ensure support strength) fixed on it provides an installation reference for the angle adjustment drive assembly. When the retention adjustment mechanism needs to be activated, the control hydraulic system 11 (using a hydraulic cylinder, with both ends rotatably connected to the drive rod 10 and the support rod 13 respectively) is activated. The hydraulic cylinder piston rod pushes the drive rod 10 to move, which in turn drives the first adjustment connecting rod 9 (made of alloy steel, rotatably connected to the hinge mounting base 15 via a pin) to rotate around the hinge mounting base 15. The first adjustment connecting rod 9 then drives the second adjustment connecting rod 12 (made of the same material as the first adjustment connecting rod 9, rotatably connected to the support rod 13 via a pin) to rotate around the support rod 14. The main rod 13 rotates, and by adjusting the angle between the first adjusting rod 9 and the second adjusting rod 12, the slag retention frame 16 is driven to rotate around the adjusting corner part 17, changing its tilt angle and thus adjusting the residence time of the slag raw material on the slag retention frame 16 (the entire operation process is similar to the existing truck tipper structure, and will not be described in detail here). At the same time, the vibrating filter 18 (driven by an electromagnetic vibrator and connected to the frame by bolts, with adjustable vibration frequency) that can be detachably installed on the slag retention frame 16 generates high-frequency vibration when the slag slides down. It has two functions: firstly, it shakes off the stubborn impurities attached to the surface of the slag raw material during the lifting process, achieving deep cleaning with the flushing water; secondly, it shakes the slag raw material during the scattering process to prevent the raw material from being retained or adhering to the vibrating filter 18, thereby ensuring a balance between slag cleaning effect and processing efficiency.

[0085] In one embodiment of the present invention, please refer to Figures 1-11 The adjustable rinsing device includes:

[0086] Water inlet 7 is provided on the cleaning shaft 1 and is connected to an external water source via an adapter.

[0087] A connecting hose 8 is provided, one end of which is fixedly installed on the cleaning shaft 1 and connected to the water inlet 7. The other end of the connecting hose 8 is connected to an adjustable jet 22.

[0088] And spray nozzles 23, there are multiple spray nozzles 23, and the multiple spray nozzles 23 are evenly distributed on the adjustable injector 22;

[0089] The spray direction of the water nozzle 23 is parallel to that of the slag retaining frame 16, and is used to wash the slag raw materials scattered from the slag retaining frame 16.

[0090] It also includes: a telescopic drive component 20, which is fixedly installed on the slag retention frame 16;

[0091] And a telescopic base 21, one end of which is connected to the telescopic drive member 20, and the other end of which is connected to the adjustable injector 22;

[0092] The telescopic drive component 20 is used to push or pull the telescopic seat 21 to move the adjustable injector 22, thereby changing the distance between the water nozzle 23 and the slag retention frame 16.

[0093] This invention achieves precise rinsing through the following structural combination: an external water source (pressurized by an industrial clean water pump, with water pressure adjustable according to slag cleaning requirements, exceeding the atmospheric pressure rinsing of existing equipment, thus enhancing decontamination capacity) is connected to the water inlet 7 on the cleaning shaft 1 via an adapter (made of brass, possessing excellent sealing and corrosion resistance, enabling connection between static and rotating states). Water flows through the water inlet 7 into the connecting hose 8 (made of high-pressure wear-resistant rubber, with a working pressure of not less than 10MPa), and then from the connecting hose 8 to the adjustable jet 22 (used to control the jet water flow). Speed ​​and flow rate; made of aluminum alloy, lightweight and high-strength, with an anodized surface for rust prevention; the adjustable injector 22 has evenly distributed spray nozzles 23 (using fan-shaped nozzles with a spray angle of 60°-120° to expand the rinsing coverage and avoid blind spots of existing circular nozzles) that direct high-pressure water flow towards the slag retaining frame 16. When the slag material falls from the slag retaining frame 16, the water flow directly impacts the surface of the slag material, washing away the attached impurities and avoiding dead corners; the telescopic drive component 20 (using an electric telescopic cylinder, specific model available) The DT series electric cylinder, which offers higher control precision than hydraulic drives and eliminates the risk of hydraulic oil leakage, is fixedly installed on the slag retention frame 16. Its piston rod is fixedly connected to the telescopic seat 21 (which uses a sliding guide rail to connect to the slag retention frame 16, ensuring smooth and uninterrupted movement). The other end of the telescopic seat 21 is fixed to the adjustable injector 22. When the control and detection system detects an unsatisfactory slag distribution location or dispersion through the slag detection equipment 24, it controls the telescopic drive component 20 to actuate. The piston rod pushes or pulls the telescopic seat 21 along the guide rail, and the telescopic seat 21 drives the adjustable injector. The adjustable spray nozzle 22 moves synchronously, changing the distance between the spray nozzle 23 and the slag retaining frame 16 to ensure that the water flow always accurately covers the slag-scattered area and makes full contact with the slag raw materials. The flexible design of the connecting hose 8 can fully adapt to the movement trajectory of the adjustable spray nozzle 22, avoiding pipe pulling and breakage. At the same time, the movable design of the adjustable spray nozzle 22 reduces the probability of slag directly impacting the spray nozzle, extending its service life, solving the problem of low accuracy of existing fixed flushing equipment, and ensuring that every particle of slag can be fully flushed, meeting the high cleanliness requirements of the slag resource recycling field.

[0094] In one embodiment of the present invention, please refer to Figures 1-11 The control and detection system includes:

[0095] A slag detection device 24 is fixedly connected to the adjustable injector 22, and there are multiple slag detection devices 24, which are evenly distributed on the adjustable injector 22.

[0096] Each of the slag detection devices 24 is equipped with a sensing unit 25. The sensing unit 25 adopts a combination of optical sensor and vibration sensor. The optical sensor (such as diffuse reflection photoelectric sensor E3Z-D61) is used to detect the dispersion of slag raw materials in a scattered state (calculated by the frequency and duration of light blocking per unit time). The vibration sensor (such as piezoelectric vibration sensor PV-981) is used to indirectly obtain the tilt angle of the slag retaining frame 16 (converted by the preset correspondence between the frame vibration frequency and the tilt angle).

[0097] The main controller is located on the external drive support structure and is used to receive the detection data transmitted by the slag detection device 24. After filtering and normalizing the data, the main controller outputs control signals to the external drive support structure (to adjust the rotation speed of the rotating cleaning cylinder 2), the adjustable flushing device (to adjust the spray parameters of the spray nozzle 23), and the angle adjustment drive component (to assist in correcting the tilt angle of the slag retention frame 16), forming a closed-loop control.

[0098] The main controller uses a programmable logic controller (PLC, specifically Siemens S7-1200) as the core control unit. Its control logic and principle are based on the normalized mapping relationship between detection parameters and execution parameters, as detailed below:

[0099] 1. Parameter definition and quantization;

[0100] The tilt angle (α) of the slag retention frame 16 is as follows: the initial state is when one end of the slag retention frame 16 (fitting arc surface 19) is in contact with the inner wall of the rotating cleaning cylinder 2 (α=0°), and the maximum tilt angle (when the frame is rotated to its limit position) is α. max =60°, the sensing unit 25 collects the vibration frequency signal through the vibration sensor, compares it with the preset vibration frequency-α calibration curve, and quantizes the signal into a specific angle value of 0° to 60°.

[0101] Since the slag retention frame 16 rotates synchronously with the rotating washing cylinder 2, and there are harsh working conditions inside such as slag impact and rinsing water immersion, the tilt angle of the slag retention frame 16 is indirectly obtained through a vibration sensor. On the one hand, this can avoid the centrifugal force generated by the rotation causing the sensor detection data to drift and the accuracy to be compromised; on the other hand, it can avoid the slag impact and water corrosion from significantly shortening the sensor life and increasing maintenance costs.

[0102] Slag dispersion (D): It is represented by the coefficient of variation of the number of times slag particles block the light of the optical sensor per unit time (1 second), D∈[0,1]; D=1 indicates that the slag is completely densely scattered (without gaps), and D=0 indicates that the slag is completely dispersed (the gaps are greater than twice the particle diameter).

[0103] Rotary cleaning drum 2 reference speed (n0): preset to 10 r / min, which is the optimal speed under normal cleaning conditions; Spray nozzle 23 reference parameters: reference water flow velocity v0 = 5 m / s, reference flow rate Q0 = 0.02 m³ / min. 3 / h (by adjustable injector 22, cross-sectional area S=4×10) -4 m 2 The calculation yields Q0 = S × v0.

[0104] 2. Normalization control;

[0105] Rotary cleaning drum 2 speed (n) control: When α increases (the frame tilts more steeply) and D increases (the slag becomes denser), the speed needs to be reduced to prolong the slag dispersion time and ensure thorough cleaning. The formula is as follows:

[0106] n = n0 × [1 - k1 × (α / α)] max )-k2×(D / D max )];

[0107] Where k1=0.3 (weighting coefficient of α) and k2=0.4 (weighting coefficient of D), both were obtained through multiple experimental calibrations; α max =60°, D max =1;

[0108] Therefore, the formula can be simplified to n=10×[1-0.3×(α / 60)-0.4D], and the calculated result n≥5r / min (to prevent slag accumulation due to excessively low rotation speed).

[0109] Spray parameter control for nozzle 23: When α and D increase, the water flow velocity and flow rate need to be increased to enhance the flushing intensity, as shown in the following formula:

[0110] ① Water flow velocity: v = v0 × [1 + k3 × (α / α)] max )+k4×(D / D max )];

[0111] Where k3=0.2, k4=0.3 (weighting coefficients), after simplification v=5×[1+0.2×(α / 60)+0.3D], v≤8m / s (to avoid excessive water pressure damaging the slag);

[0112] ② Water flow rate: Since the cross-sectional area S of the adjustable jet 22 is fixed, the flow rate is proportional to the velocity, and the formula is Q=S×v. That is, Q changes synchronously with v, and no additional independent calculation is required.

[0113] 3. Control execution and feedback;

[0114] The main controller receives the detection data from the sensing unit 25 in real time via the RS485 communication interface, performs the above formula calculation every 0.5 seconds, and outputs a PWM (Pulse Width Modulation) signal to:

[0115] The variable frequency motor of the external drive support structure adjusts the actual rotational speed n of the rotating cleaning drum 2;

[0116] The adjustable flushing equipment includes a high-pressure water pump (controlling the water flow speed v) and a telescopic drive 20 (assisting in adjusting the position of the adjustable jet 22 to ensure that the water flow covers the slag-scattered area).

[0117] Meanwhile, the main controller receives signals from the motor encoder (feedback n) and the flow sensor (feedback Q). If the deviation between the actual parameters and the calculated values ​​exceeds 5%, the weighting coefficients of k1 to k4 are dynamically adjusted until the deviation is less than 3%, thus achieving precise closed-loop control.

[0118] The workflow of the control and detection system includes the following steps:

[0119] Initialization Startup: After the equipment is powered on, the main controller automatically executes the initialization program, setting the rotational speed of the rotating cleaning drum 2 to the reference speed n0 = 10 r / min, the water flow velocity of the spray nozzle 23 to v0 = 5 m / s, and the flow rate to Q0 = 0.02 m³ / min. 3 / h, the slag retention frame 16 is reset to the fitting state (α=0°), and all slag detection devices 24 and sensing units 25 enter the preheating state (lasting for 10 seconds to ensure sensor stability).

[0120] Slag introduction and detection start-up: The operator introduces slag raw materials into the rotating washing cylinder 2 through the material inlet 4 on the cleaning screen 3, and closes the material inlet 4 after the introduction is completed; after receiving the material inlet closing signal, the main controller sends an instruction to the slag detection equipment 24 to start the real-time detection of the sensing unit 25 (collecting α and D data once every 0.5 seconds).

[0121] Data processing and parameter calculation: The main controller filters the α (tilt angle) and D (discretion) data transmitted by the sensing unit 25 (removing outliers caused by electromagnetic interference), substitutes them into the normalized control formula above, and calculates the required rotational speed n of the rotating cleaning drum 2, the water flow velocity v of the spray nozzle 23, and the flow rate Q.

[0122] Actuator action: Main controller outputs control signal:

[0123] The variable frequency motor that controls the external drive support structure adjusts the speed from the current value to the calculated value n;

[0124] Control the high-pressure water pump of the adjustable flushing equipment to adjust the water flow rate to v, and simultaneously feed back the Q value through the flow sensor to ensure that Q = S × v;

[0125] If D≥0.8 (slag is too dense), the hydraulic system 11 of the additional angle-adjusting drive component is used to push the slag retention frame 16 to increase the tilt angle α (up to 60°) to assist in slag dispersion.

[0126] Closed-loop feedback and adjustment: The main controller receives real-time feedback from the motor encoder (feedback of the actual speed n). 实 ), flow sensor (feedback of actual flow rate Q) 实 The signal is used to calculate the deviation rate (e.g., |n) 实 -n| / n×100%); if the deviation rate is >5%, then correct the weight coefficients of k1 to k4 (if the deviation is caused by inaccurate α detection, increase the value of k1), recalculate and output the control parameters until the deviation rate is ≤3%.

[0127] Cleaning completion judgment and shutdown: The optical sensor of the sensing unit 25 simultaneously detects the cleanliness of the slag surface (judged by the intensity of reflected light; the intensity of reflected light from clean slag is higher than the preset threshold); when the slag cleanliness is detected to be up to standard +D∈[0.2,0.5] (moderate dispersion) for 30 consecutive seconds, the main controller determines that the cleaning is complete and controls the following in sequence: the adjustable flushing equipment stops → the rotation speed of the rotating cleaning drum 2 is reduced to 3r / min (for easy discharge) → the slag retention frame 16 is reset → the operator opens the material port 4 to discharge the slag, and finally the equipment returns to the initialization state, waiting for the next start-up.
