Description

Technical Field

[0001] The invention belongs to the technical field of dust cleaning, and in particular relates to a radar array fixed-point dust collection system. Background Art

[0002] In the field of industrial production, energy conservation, emission reduction, environmental protection and sustainable development have become irreversible development trends. Especially in industries such as recycled aggregate brick making, the raw material yard is often accompanied by a large amount of dust during loading and unloading. In order to create a dust-free and environmentally friendly production workshop, efficient removal of dust and other pollutants in the air is a crucial link. By adopting advanced dust removal technology and equipment, it can not only significantly improve the working environment, but also effectively reduce pollution to the environment, and promote enterprises to move towards green and environmental protection. At the same time, these technologies should also focus on energy-saving design to ensure that while improving air quality, it can also reduce energy consumption and achieve true green production.

[0003] The contents of the traditional design of recycled aggregate brick raw material storage and transfer workshop are:

[0004] 1. Raw material storage area: The raw material storage area is a storage area for various raw materials for preparing imitation stone bricks. The raw materials include silt sand, coarse aggregate from construction waste, fine aggregate from construction waste, coarse aggregate from steel slag, fine aggregate from steel slag, cement, white cement, etc.

[0005] 2. Raw material transfer equipment: forklift, belt conveyor, screw conveyor, etc.

[0006] 3. Dust removal system: bag dust collector system.

[0007] During the transportation of recycled aggregate brick raw materials, the transportation of raw materials involves multiple links: first, the forklift transports the raw materials to the corresponding raw material bin; then the belt conveyor or screw conveyor transports them to the mixer. In this process, a large amount of industrial dust will be generated when the forklift unloads the materials into the raw material bin. In order to effectively control the dust in the workshop, a bag dust collector must be equipped to achieve this.

[0008] Since there are many kinds of raw materials for recycled aggregate brick making and the dust content is high, a production line contains at least five kinds of raw materials: silt sand, coarse aggregate from construction waste, fine aggregate from construction waste, coarse aggregate from steel slag, and fine aggregate from steel slag. Because there are at least five raw material silos, these raw materials are transported from the storage area to the batching silo by a forklift. Therefore, a production line must contain at least five dust collection points.

[0009] When forklifts transport the corresponding raw materials from the storage area to the batching silo, they do not do so simultaneously. Due to the relatively small capacity of the batching silo, the large amount of forklifts transported, and the different proportions of raw materials used, raw material transportation is often replenished by forklifts after the raw materials are consumed to a certain extent. This asynchronous raw material replenishment method makes dust generation more frequent during the unloading process. Therefore, a bag dust collection system must be added to each raw material silo to prevent a large amount of industrial dust.

[0010] Due to the various types of raw materials and multiple production lines, there must be multiple raw material warehouses in the same raw material storage workshop, and all of them should have dust collection points to prevent large amounts of industrial dust from polluting the environment and harming the health of employees.

[0011] In a traditional brick production workshop, a production line is usually equipped with five raw material silos, which are used to store raw materials of different particle sizes, such as steel slag coarse aggregate, steel slag fine aggregate, silt sand, construction waste coarse aggregate and construction waste fine aggregate. In order to effectively control dust, each raw material silo is traditionally equipped with a bag dust collector. However, due to the irregular transportation of raw materials, this configuration often causes the dust collection equipment to run idle during non-working hours, resulting in significant energy waste. In addition, the increased number of dust collection equipment also means higher procurement and maintenance costs.

[0012] If one tries to solve this problem by equipping five raw material silos with a high-power bag dust collector, although the number of devices can be reduced, this approach may result in a significant increase in the power of the dust collector to ensure that all dust collection points can obtain sufficient air volume, which will also cause a lot of energy loss. Summary of the invention

[0013] The purpose of the present invention is to overcome the problems of the prior art and disclose a radar array fixed-point dust collection system, which monitors the vehicle dynamics of each raw material conveying lane in real time and accurately controls the dust collection pipeline valve of the corresponding raw material bin accordingly. This intelligent control mechanism ensures that the bag dust collector can work specifically in the bin where the raw material is being conveyed, thereby ensuring that each dust collection point can obtain sufficient air volume and realize accurate and efficient dust collection.

[0014] The object of the present invention is achieved through the following technical solutions:

[0021] According to a preferred embodiment, the valve control logic in each pipeline in the air duct network unit includes: when the radar detection switch of the lane corresponding to the raw material storage unit obtains a signal, if the valve of the corresponding pipeline in the air duct network unit is currently in an open state, it remains unchanged; if it is in a closed state, it is automatically opened; for the lanes corresponding to other raw material storage units, if the valve of the corresponding pipeline in the air duct network unit is in an open state, it is closed; if it is in a closed state, it remains unchanged.

[0022] According to a preferred embodiment, the valve control logic in each pipeline in the air duct network unit also includes: once the valve of the corresponding pipeline in the air duct network unit corresponding to the response lane is opened due to the radar detecting a vehicle, the valve will continue to remain open, even if the radar detection signal of the lane disappears. The valve will only be closed when the radar of other lanes detects a vehicle signal and the radar monitoring device of the lane does not detect a vehicle.

[0023] According to a preferred embodiment, the intelligent control unit realizes the valve action of the corresponding pipeline in the air duct network unit through a matrix control method to achieve precise dust collection control.

[0024] According to a preferred embodiment, the matrix control method controls the opening and closing of the valve according to the real-time status of the vehicle lane, including:

[0025] a. Define input and output:

[0026] Input: sensor signal of vehicle lane;

[0028] b. Create a control matrix:

[0029] Define a matrix M, whose elements represent the mth ij The impact of a radar monitoring device on the action of the i-th valve.

[0030] According to the needs of dust collection control, the control matrix is ​​optimized to ensure that the corresponding valves can be opened in time to collect dust when the vehicle passes, and closed after the vehicle passes to save energy;

[0031] c. Write a program:

[0032] Use PLC programming language to write programs;

[0033] Read the status of the radar detection switch and store it in the input register of the PLC;

[0035] The calculation result is output to the control signal of the valve to control the opening and closing of the valve.

[0036] According to a preferred embodiment, each radar monitoring device in the radar monitoring unit is located directly above the center line of the lane corresponding to each raw material storage unit, and is used to monitor the dynamics of the raw material transportation vehicle in real time.

[0037] According to a preferred embodiment, in the filter unit, when the dust-containing gas enters the ash hopper through the guide plate, the coarse dust will fall into the ash hopper due to the collision of the guide plate and the reduction of the gas velocity, and the remaining fine dust particles will enter the filter bag chamber with the gas, and the dust will be retained in the filter bag. The purified gas escapes from the bag and is discharged through the exhaust pipe of the dust collection unit.

After understanding the scheme of the present invention, those skilled in the art can understand that there are multiple combinations based on the prior art and common knowledge, all of which are technical schemes to be protected by the present invention, and they are not exhaustively listed here.

[0050] refer to Figure 1 and Figure 2 As shown in the figure, a radar array fixed-point dust collection system is shown, and the radar array fixed-point dust collection system includes: a radar monitoring unit 1, an actuator unit 2, a raw material storage unit 3, an air duct network unit 4, a filtering unit 5, a dust suction unit 6, a raw material unloading duct network unit 7 and an intelligent control unit 8.

[0051] The dust collecting unit 6 is connected to the air duct network unit 4 via the filtering unit 5, and each pipe in the air duct network unit 4 is connected to the corresponding area of ​​each raw material storage unit 3; the radar monitoring unit 1 includes a number of radar monitoring devices, which are used to complete the vehicle detection on the corresponding lane of each raw material storage unit 3, and the raw material storage unit 3 is used to receive the raw materials transported by the vehicle; the actuator unit 2 is used to complete the valve opening or closing control of each pipe in the air duct network unit 4. The materials in the raw material storage unit 3 are transported to the downstream mixing equipment through the raw material unloading pipe network unit 7 to prepare the imitation stone bricks; the intelligent control unit 8 controls the actuator unit 2 to open and close the pipe valves in the corresponding area of ​​the air duct network unit 4 based on the monitoring results of the radar monitoring unit 1, so as to realize the precise and fixed-point collection of dust.

[0052] The filter unit 5 includes a filter bag, a screw conveyor, a rotary discharger, a pulse valve group, etc. When the dust-containing gas enters the ash hopper through the guide plate from the lower air inlet pipe of the filter unit 5, the coarse dust will fall into the ash hopper due to the collision of the guide plate and the reduction of the gas velocity. The remaining fine dust particles enter the filter bag chamber with the gas, and the dust is retained in the filter bag. The purified gas escapes from the bag and is discharged through the exhaust pipe of the dust collection unit 6. The material in the ash hopper is discharged to the ash conveying device through the double-layer ash discharge valve. The accumulated dust on the filter bag is removed by spraying pulse airflow, so as to achieve the purpose of cleaning. The removed dust is discharged by the ash discharge device (screw conveyor, rotary discharger).

[0053] As the core component, the intelligent control unit 8 integrates the PLC (programmable logic controller) logic control system and a variety of electrical control components. These components work together through precise program logic and electrical actions to ensure the efficient operation of the dust collection system. The PLC system is responsible for processing and executing the preset control logic, while the electrical components are responsible for performing specific operations, such as switch control, signal transmission, etc., to jointly ensure the automation and precise control of the dust collection process. This integrated design not only improves the reliability and efficiency of the system, but also simplifies the operating process, allowing the dust collection system to respond to production needs more intelligently and optimize environmental management.

[0054] The radar monitoring unit 1 uses advanced detection technology to transmit a detection signal of a specific frequency and receive the signal reflected by the target object (such as a vehicle). This process involves complex signal processing, including signal reception, analysis and interpretation. After precise signal processing, the radar detection device can output a switch signal that clearly indicates whether there is a vehicle in the target area. This efficient detection mechanism not only improves the accuracy of detection, but also enhances the response speed and reliability of the system, ensuring the real-time and effectiveness of vehicle monitoring.

[0055] The actuator unit 2 is a control device that opens or closes a corresponding pipeline on the air pipe network unit 4. Its main function is to control the flow of the medium in the pipeline. When the gate is in the open state, the valve allows the medium to flow freely, ensuring the efficient operation of the pipeline. On the contrary, when the gate is closed, the valve effectively cuts off the flow of the medium, achieving precise control of the pipeline system.

[0056] After the radar detection device is started, the operator uses Bluetooth technology to search and connect to the corresponding radar detection device through the smartphone APP. Through the APP, the key parameters of the radar are set, including the detection distance and shutdown delay time, and these configuration information will be written into the internal storage of the radar detection device. In order to ensure the accuracy and reliability of the radar detection device, the operator needs to clear the debris around the device and perform environmental calibration on the device. This step ensures that the detection range of the radar is accurately controlled within the required range, thereby effectively avoiding false alarms caused by moving objects such as personnel or small forklifts. Through this sophisticated configuration and calibration process, the radar detection device can provide stable and accurate monitoring results in complex industrial environments, providing strong support for the safety and management of production workshops.

[0057] The power supplies of the radar monitoring unit 1, the actuator unit 2, the filter unit 5 and the dust collection unit 6 are all provided by the intelligent control unit 8. The control signals of these devices, including radar detection signals, valve limit signals and device status signals (such as ready, fault, running, driving, etc.), are all connected to the PLC of the intelligent control unit 8. The PLC uses these signals to execute the preset control logic (such as Figure 2 to ensure the coordinated operation of the entire dust collection system.

[0058] During production activities on the production line, the filter unit 5 and the dust collection unit 6 will be started synchronously to ensure the normal operation of the dust collection system. In order to protect the equipment from damage caused by excessive negative pressure, when the dust collector operation signal is triggered, the actuator unit 2 on all dust collection pipes will be automatically opened to the open state.

[0059] When the radar monitoring unit 1 in the lane corresponding to a raw material warehouse detects a vehicle approaching, the system will perform corresponding operations according to the current state of the actuator unit 2: if the valve is already in the open state, it will remain unchanged; if the valve is in the closed state, it will automatically open. At the same time, for other lanes, if their valves are currently in the open state, they will be closed; if they are in the closed state, they will remain unchanged.

[0060] Specifically, when the dust collection system is started, the radar monitoring unit 1 is activated to monitor the approach and departure of vehicles in real time. The matrix control programming of the valve action is realized through the intelligent control unit 8 to achieve precise dust collection control, and a program is designed that controls the opening and closing of the valve according to the real-time status of the vehicle lane.

[0061] The simplified steps are as follows:

[0062] 1. Define input and output:

[0063] Input: Sensor signals of the vehicle’s lane, such as the state of a radar detection switch.

[0064] Output: Valve control signal, used to open or close the valve.

[0065] 2. Create a control matrix:

[0066] Define a matrix whose elements represent the influence of the th radar monitoring device on the th valve action.

[0067] According to the needs of dust collection control, the control matrix is ​​optimized to ensure that the corresponding valves can be opened in time for dust collection when the vehicle passes, and closed after the vehicle passes to save energy.

[0068] 3. Write a program:

[0069] Use PLC programming language to write programs;

[0070] Read the status of the radar detection switch and store it in the input register of the PLC;

[0071] According to the control matrix, calculate the valve that should be opened;

[0072] The calculation result is output to the control signal of the valve to control the opening and closing of the valve.

[0073] 4. Implement optimization logic:

[0074] Implement optimization algorithms in the program, such as using linear programming or integer programming to determine the best valve control strategy.

[0075] Considering the real-time status and historical data of the system, the control matrix is ​​dynamically adjusted to adapt to different operating conditions and optimization objectives.

[0076] 5. Testing and debugging:

[0077] Test the PLC program in the actual system to ensure that the valve can be accurately controlled according to the real-time status of the vehicle lane.

[0078] Debug the program and optimize the control logic to ensure that the system can run stably under various circumstances.

[0079] Through the above steps, a PLC-based valve control program is implemented, which can accurately control the movement of the valve according to the real-time status of the vehicle lane, thereby achieving efficient dust collection control.

[0080] For example, the specific control strategy uses a matrix to represent the specific correspondence between five radar detection switches and five valve actions: the state of the radar detection switch is represented by a column vector, and the state of the valve action is represented by another column vector. A matrix is ​​defined, whose elements represent the mapping of the radar monitoring device state to the valve action state.

[0081] Assume the state vector of the radar detection switch is:

[0082]

[0083] where s i Indicates the status of the i-th radar monitoring device (1 means on, 0 means off).

[0084] Similarly, let the valve action state vector be

[0085]

[0086] where v i Indicates the operating status of the i-th valve.

[0087] Therefore, we define a 5×5 matrix M, whose element m ij represents the influence of the ith radar monitoring device on the jth valve action. If the ith radar monitoring device will cause the jth valve to act when it is turned on, then m ij =1, otherwise m ij =0.

[0088] Therefore, the state vector V of the valve action can be obtained from the state vector S of the radar monitoring device by matrix multiplication:

[0089] V=M·S

[0090] For example: If the matrix M is:

[0091]

[0092] This means that each radar monitoring device only controls the corresponding valve, without cross-effect.

[0093]

[0094] Then the valve action state V is:

[0095]

[0096] This means that only the first, third and fifth valves will operate.

[0097] Through the programmable logic controller, the matrix control programming and debugging of the valve action can effectively realize the valve action of the lane with vehicles and realize the precise fixed-point dust collection control. Once the valve of the response lane is opened due to the radar detecting the vehicle, the valve will remain open until the other lanes detect the vehicle signal and the radar of this lane does not detect the vehicle. This intelligent control strategy ensures that the dust collection system can respond to the actual needs of the production site in a targeted manner and improves the efficiency and flexibility of the system.

[0098] When the filter unit 5 and the dust collection unit 6 stop working, all actuator units 2 will automatically shut down to ensure the safe shutdown of the system and effective energy conservation. Through this precise control logic, the dust collection system in the production workshop not only achieves efficient operation, but also optimizes energy use and reduces unnecessary energy consumption.

[0099] The present invention uses an intelligent detection system to monitor the vehicle dynamics of each raw material conveying lane in real time, and accurately controls the dust collection pipeline valve of the corresponding raw material bin accordingly. This intelligent control mechanism ensures that the bag dust collector can work specifically in the bin where the raw material is being conveyed, thereby ensuring that each dust collection point can obtain sufficient air volume and achieve accurate and efficient dust collection.

[0100] This precise dust collection strategy significantly improves the economic benefits, environmental performance, work efficiency and energy saving level of the production workshop. This innovation not only helps to reduce energy waste and operating costs, but also effectively improves the working environment and protects the health of employees, while meeting the modern industry's pursuit of sustainable development. By integrating intelligent detection and control systems, this invention provides an efficient, environmentally friendly and economical solution for the brick-making industry, promoting technological progress in the entire industry.

[0101] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
