Description

Technical Field

[0001] The present application relates to the technical field of sand and gravel processing, and in particular to a sand and gravel processing detection and control method, system, terminal and storage medium. Background Art

[0002] Artificial sand refers to sand processed by sand making machines and other ancillary equipment. The finished product is more regular and can be processed into sand of different rules and sizes according to different process requirements, which can better meet daily needs. Artificial sand requires professional equipment to make qualified sand and gravel; in the sand and gravel production line, to produce qualified sand and gravel, it is necessary to go through two major processes of crushing and screening. The sand and gravel particle size that determines the production of products that meet the standards requires good screening equipment for screening. Screening and crushing work directly with each other to produce sand and gravel products that meet the standards, ensuring the quality of sand and gravel aggregates in concrete, and thus ensuring the quality of the building.

[0003] At present, in sand and gravel processing operations, the processing efficiency of sand and gravel processing is generally controlled by uniform feeding through a feeder, that is, large pieces of ore are evenly fed into the coarse crusher through the feeder to control the amount of sand and gravel in the crusher (i.e., coarse crusher, medium crusher and fine crusher) and the screening machine, so that the crusher and the screening machine meet the appropriate working efficiency, thereby controlling the processing efficiency of sand and gravel processing. This process often requires experienced staff to operate; however, relying solely on uniform feeding to control the processing efficiency, the coordination ability of the two processes of screening and crushing is insufficient. For example, there is a situation where qualified sand and gravel are repeatedly crushed, which may cause the sand and gravel processing equipment to be damaged due to excessive working power, or cause waste of productivity of the sand and gravel processing system.

[0058] This specific embodiment is merely an explanation of the present application and is not a limitation of the present application. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but as long as they are within the scope of the claims of the present application, they are protected by the patent law.

[0059] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0060] The embodiments of the present application are described in further detail below with reference to the accompanying drawings.

[0061] In common sand and gravel processing technology, large pieces of ore must first be processed by a coarse crusher. After coarse crushing, they are screened using a screening machine. Only qualified stones that pass the screening requirements can enter the fine crusher for fine crushing. Similarly, the finished stone products after fine crushing must also be screened by a screening machine. Only qualified ones that meet the finished product specification requirements can be transported to the finished product warehouse using a belt conveyor. Those that do not meet the requirements will be returned for fine crushing until they are qualified. This cycle continues to complete batch operation requirements. According to specific operating conditions, in some sand and gravel processing technologies, a medium crushing operation is also set between the coarse crushing operation and the fine crushing operation. The overall process flow is feeding - coarse crushing - screening - medium crushing - screening - fine crushing - screening - warehousing.

[0062] At present, in sand and gravel processing operations, the processing efficiency of sand and gravel processing is generally controlled by uniform feeding through a feeder, that is, large pieces of ore are evenly fed into the coarse crusher through the feeder to control the amount of sand and gravel in the crusher (that is, the coarse crusher, the medium crusher and the fine crusher) and the screening machine, so that the crusher and the screening machine meet the appropriate working efficiency, thereby controlling the processing efficiency of sand and gravel processing. This process often requires experienced staff to operate; however, relying solely on uniform feeding to control the processing efficiency, the coordination ability of the screening and crushing processes is insufficient, which may cause the sand and gravel processing equipment to be damaged due to excessive working power, or cause waste of productivity of the sand and gravel processing system; usually, there are many situations in the particle size composition of sand and gravel in the screening machine. A sand and gravel processing detection and control method in this application adjusts the working power of the sand and gravel processing process according to the particle size structure of sand and gravel in each screening process, optimizes the operation coordination of each process of the sand and gravel processing system, thereby avoiding damage to the sand and gravel processing equipment due to excessive working power and avoiding waste of productivity of the sand and gravel processing system.

[0063] like Figure 1 As shown, in an embodiment of the present application, an operating environment of a sand and gravel processing detection and control method includes a sand and gravel processing monitoring system, a sand and gravel processing detection and control system, and a sand and gravel processing equipment control system; wherein, the sand and gravel processing detection and control system is the operating entity of a sand and gravel processing detection and control method in the present application; the sand and gravel processing monitoring system includes a monitoring camera and a gravity sensor, and the monitoring camera and the gravity sensor are both arranged on the screening machine. The monitoring camera is used to collect the surface sand and gravel images of the sand and gravel accumulated in the screening machine, and the gravity sensor is used to collect the total weight of the sand and gravel accumulated in the screening machine. It should be noted that the monitoring cameras here are arranged at multiple positions on the screening machine to collect surface sand and gravel images as completely as possible from multiple angles; the sand and gravel processing equipment control system includes controllers of each processing equipment, and the working power of the equipment is controlled by the sand and gravel processing equipment control system.

[0064] In an embodiment of the present application, the sand and gravel processing detection and control system is connected to the sand and gravel processing monitoring system and the sand and gravel processing equipment control system. The surface sand and gravel images and sand and gravel weights collected by the sand and gravel processing monitoring system are transmitted to the sand and gravel processing detection and control system. The sand and gravel processing detection and control system first analyzes the particle size structure of the sand and gravel in the screening machine based on the surface sand and gravel images and sand and gravel weight, and then uses the sand and gravel processing equipment control system to adjust the working power of the sand and gravel processing process based on the particle size structure, thereby improving the operational coordination ability of each process of the sand and gravel processing system.

[0065] The present application provides a sand and gravel processing detection and control method, and the main process of the method is described as follows.

[0066] like Figure 2 As shown:

[0067] Step S101: Based on the sand and gravel processing process, detect and obtain sand and gravel information in the screening process.

[0068] In an embodiment of the present application, the sand and gravel information includes surface sand and gravel images and sand and gravel weight information; wherein, the surface sand and gravel image refers to the image of the surface layer of the sand and gravel accumulated in the screening machine, which is obtained by image fusion processing of multiple surface sand and gravel images collected by multiple monitoring cameras in the above-mentioned sand and gravel processing monitoring system; the sand and gravel weight information refers to the total weight of the sand and gravel accumulated in the screening machine.

[0069] Step S102: Analyze and obtain the sand and gravel particle size structure based on the sand and gravel information.

[0070] like Figure 3 As shown, in the embodiment of the present application, the sand and gravel particle size structure of the sand and gravel accumulated in the screening machine is analyzed based on the surface sand and gravel image and sand and gravel weight information obtained in step S101.

[0071] Specifically, first, the surface sand and gravel image is contour processed to obtain the surface sand and gravel distribution information and the particle size change trend of the surface sand and gravel; among them, the surface sand and gravel distribution information refers to the position and contour boundary of each sand and gravel in the surface sand and gravel, and the particle size change trend refers to the trend of particle size change of each sand and gravel in the surface sand and gravel extending to the bottom layer.

[0072] Then, according to the above-mentioned particle size change trend, particle size matching is performed in the preset sand and gravel model library, and the preset sand and gravel model with the highest matching degree is used as the shape model of the corresponding surface sand and gravel, and then the corresponding surface sand and gravel particle size information is obtained. The surface sand and gravel particle size information refers to the particle size value of the surface sand and gravel, and each surface sand and gravel corresponds to multiple particle size values; among them, the preset sand and gravel model library refers to the three-dimensional models of a large number of sand and gravel finished products and intermediate products in the sand and gravel processing process, and the particle size information of these sand and gravel finished products and intermediate products.

[0073] Next, a surface sand and gravel model is constructed based on the above-mentioned surface sand and gravel distribution information and surface sand and gravel particle size information; after obtaining the position, contour boundary and particle size value of each sand and gravel in the surface sand and gravel, a surface sand and gravel model is constructed based on the position, contour and particle size value; then, based on the surface sand and gravel model, the surface sand and gravel volume and the bottom sand and gravel gap are analyzed; the surface sand and gravel volume is obtained by performing model volume analysis on the surface sand and gravel model; the bottom sand and gravel gap is obtained by analysis through the surface sand and gravel model and the screening machine equipment structure.

[0074] At the same time, information about the sand and gravel raw materials is collected to obtain the density, moisture content, and water absorption rate of the sand and gravel raw materials. Then, the sand and gravel volume information is calculated based on the sand and gravel raw material information and sand and gravel weight information. The sand and gravel volume satisfies the following formula:

[0075] V = M × [1 - (R + K × H)];

[0076] g

[0077] Among them, V represents the volume of sand and gravel; M represents the weight of sand and gravel; R represents the moisture content of sand and gravel raw materials; K represents the water absorption rate of sand and gravel raw materials; H represents the immersion time of sand and gravel; g represents the density of sand and gravel raw materials; it can be understood that during the crushing operation of sand and gravel, water will be continuously injected into the crusher, so the sand and gravel in the crusher are close to being in a water-immersed environment and continue to absorb water. Here, H represents the immersion time of sand and gravel, and according to the sand and gravel processing process, the immersion time gradually increases.

[0078] Next, based on the above-mentioned preset sand and gravel model library, the bottom sand and gravel model is analyzed and constructed according to the surface sand and gravel volume, the bottom sand and gravel gap and sand and gravel volume information; first, the surface sand and gravel volume is subtracted from the sand and gravel volume to obtain the bottom sand and gravel volume; then, according to the bottom sand and gravel volume and the bottom sand and gravel gap, the appropriate sand and gravel particle size is matched from the preset sand and gravel model library, and filled into the bottom sand and gravel gap, and the filling volume is analyzed and obtained according to all the filled sand and gravel particle sizes to make it equal to the bottom sand and gravel volume.

[0079] Finally, based on the surface sand and gravel model and the bottom sand and gravel model, the sand and gravel particle size structure is analyzed and obtained. The sand and gravel particle size structure refers to the sand and gravel particle size specification table.

[0080] Step S103: Based on the preset process control rules, the sand and gravel processing process is controlled according to the sand and gravel particle size structure.

[0081] In an embodiment of the present application, based on the sand and gravel processing process, first, according to the above-mentioned sand and gravel particle size structure, the qualified ratio of the sand and gravel particle size in each screening process is sorted out; then the qualified ratio is compared with the preset ratio threshold interval of the corresponding screening process: when the qualified ratio is greater than the larger value of the preset ratio threshold interval, the working power of the sand and gravel processing process before the current screening process is reduced, and / or the working power of the current screening process is increased; when the qualified ratio is less than the smaller value of the preset ratio threshold interval, the working power of the sand and gravel processing process before the current screening process is increased.

[0082] It is understandable that when the qualified proportion of sand and gravel in a certain screening process is large, it may be that the crusher before this screening process is operating under overload. At this time, reducing the working power of the sand and gravel processing process before the current screening process can better protect the sand and gravel processing equipment. When the qualified proportion is large, it is very likely that sand and gravel with qualified particle size will return to the previous crushing process, wasting the productivity of the sand and gravel processing system. Increasing the working power of the current screening process will reduce the return of sand and gravel with qualified particle size and avoid waste of productivity of the sand and gravel processing system. When the qualified proportion of sand and gravel in a certain screening process is small, it means that the crushing degree of the previous crushing process is insufficient. Increasing the working power of the sand and gravel processing process before the current screening process can improve the crushing degree and avoid waste of productivity of the sand and gravel processing system.

[0083] In an embodiment of the present application, based on the sand and gravel processing process, first, according to the sand and gravel particle size structure, the sand and gravel distribution density and sand and gravel accumulation volume in each screening process are sorted out; then the sand and gravel distribution density is compared with the preset density threshold of the corresponding screening process, and the sand and gravel accumulation volume is compared with the preset volume threshold of the corresponding screening process: when the sand and gravel distribution density is greater than the preset density threshold, and the sand and gravel accumulation volume is greater than the preset volume threshold, the working power of the sand and gravel processing process before the current screening process is reduced, and / or the working power of the current screening process is increased.

[0084] It is understandable that when the density of sand and gravel is high and the volume of sand and gravel accumulation is large, under the influence of friction, the screening efficiency of the screening machine is likely to be reduced greatly, causing sand and gravel of qualified particle size to return to the previous crushing process, resulting in waste of productivity of the sand and gravel processing system and increasing the working pressure of the screening machine; reducing the working power of the sand and gravel processing process before the current screening process, such as reducing the conveying rate of the conveying equipment before the current screening process, reducing the increase of sand and gravel in the current screening machine, increasing the working power of the current screening process, and improving the screening efficiency of the current screening machine, thereby avoiding waste of productivity of the sand and gravel processing system and damage to the screening machine.

[0085] This application also provides a sand and stone processing detection and control system, such as Figure 4As shown, a sand and gravel processing detection and control system includes: a detection module 1, which is used to detect and obtain sand and gravel information based on the sand and gravel processing process; the sand and gravel information includes surface sand and gravel images and sand and gravel weight information; an analysis module 2, which is used to analyze and obtain sand and gravel particle size structure based on the sand and gravel information; and a control module 3, which is used to control the sand and gravel processing process based on the sand and gravel particle size structure based on preset process control rules.

[0086] In order to better execute the program of the above method, the present application also provides a terminal, which includes a memory and a processor.

[0087] The memory can be used to store instructions, programs, codes, code sets, or instruction sets. The memory can include a program storage area and a data storage area. The program storage area can store instructions for implementing an operating system, instructions for at least one function, and instructions for implementing the sand and stone processing detection and control method, etc.; the data storage area can store data involved in the sand and stone processing detection and control method, etc.
