[0045] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution of the present application will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.

[0046] The terms "including" and "having" and any variations thereof mentioned in the embodiments of the present application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device including a series of steps or units is not limited to the listed steps or units, but may optionally include other steps or units that are not listed, or may optionally include other steps or units that are inherent to these processes, methods, products or devices.

[0047] At present, the traditional X-ray intelligent dry sorting machine identifies objects and locates their positions through material absorption. It cannot directly identify adhesions like traditional images. When some ore with mud enters the intelligent dry sorting machine, the mud will adhere to the belt conveyor together with small particles. Traditional belt cleaners such as brushes and rubber have poor mud cleaning effects, which will make some adhesions difficult to clean. The method of adding flushing water to the entire cross-section will cause a large waste of water resources. The flushing water entering the belt will also cause problems such as belt slippage and equipment rust, which will cause equipment shutdown in severe cases. At present, it is not possible to accurately identify and remove stubborn adhesions on X-ray-based intelligent dry sorting machines.

[0048] Based on this, the embodiments of the present application provide a method, device and electronic device for processing adhesions on a belt conveyor. This method can solve the technical problems of low recognition accuracy of particles adhered to the belt of the belt conveyor and inability to remove them at a fixed point.

[0049] The embodiments of the present invention are further described below in conjunction with the accompanying drawings.

[0050] Figure 1The following is a flow chart of a method for treating adhesions on a belt conveyor provided in an embodiment of the present application. Figure 1 As shown, the method includes:

[0051] Step S110, obtaining X-ray image information on the belt conveyor during the sorting process through an X-ray recognition system, and determining the particle size of each particle on the belt conveyor according to the X-ray image information.

[0052] Among them, the X-ray recognition system is the X-ray recognition system built into the dry sorter, that is, the detection and positioning of the adhesions adopts the X-ray recognition system built into the dry sorter. In addition to the analysis required for normal sorting, the screening and positioning functions of adhesions are added during the sorting process.

[0053] Step S120, determining whether the particle size is smaller than a preset lower limit particle size threshold.

[0054] As a possible real-time method, based on experience analysis of common feed particle sizes, the feed lower limit is set, that is, the feed lower limit particle size threshold is preset. For example, a device with a feed particle size of +50mm may have some 50-30mm particles, so the particle size lower limit is set to 30mm. The size of each particle is counted based on the X-ray image information to determine whether the particle size is less than the feed lower limit.

[0055] Step S130: If the particle size is smaller than the preset lower limit particle size threshold of the feed material, the first particle smaller than the preset lower limit particle size threshold of the feed material is determined as an initial adhesion.

[0056] In an optional embodiment, if Figure 2 As shown, if the particle size is smaller than the lower limit of the feed, the object will be included in the database of suspected adhesions.

[0057] Step S140, determining a target time interval for the next entry of the initial adhesion into the X-ray recognition system according to the total belt length, belt speed and belt speed fluctuation of the belt conveyor.

[0058] Exemplarily, this step may specifically include the following steps: according to the total belt length, belt speed and belt speed fluctuation of the belt conveyor, determine the target time interval for the initial adhesion to enter the X-ray recognition system next time by the following formula:

[0059] [t1*k1,t2*k2], t1=L / (v0+Δv), t2=L / (v0-Δv);

[0060] Wherein, L is the total length of the belt, v0 is the belt speed, Δv is the belt speed fluctuation, [t1*k1, t2*k2] is the target time interval, k1 and k2 are preset adjustment coefficients, and the preset adjustment coefficients are used to expand the cleaning range, k1 is less than 1 and k2 is greater than 1.

[0061] It can be seen that according to the total belt length L, belt speed v0 and belt speed fluctuation Δv, the reasonable time interval t1=L / (v0+Δv) and t2=L / (v0-Δv) for the adhesion to enter the identification system next time is calculated, and the setting interval is [t1*k1,t2*k2], where k1 and k2 are adjustment coefficients used to expand the cleaning range. Generally, k1 is less than 1 and k2 is greater than 1.

[0062] Step S150: within the target time interval, it is determined again whether there are second particles similar to the initial adhesion at the corresponding position of the initial adhesion on the belt.

[0063] For subsequent cycle judgment, such as Figure 2 As shown, within the above-mentioned time period, it is determined again whether there are similar particles at this position from many aspects such as particle shape and X-ray absorption capacity. If such particles exist, the following step S160 is executed.

[0064] Step S160: If there is a second particle similar to the initial adhesion, the second particle is determined as the final adhesion, and information of the final adhesion is sent to the data processing end.

[0065] The information of the final adhesion includes the corresponding position of the final adhesion on the belt. For example, if the particle exists, the particle is recorded as an adhesion particle, and its corresponding position is sent to the processing center.

[0066] In the embodiment of the present application, as a method for positioning and identifying adhesions on a belt conveyor, a material distributor with a distribution function can also be used. The X-ray image information obtained by the X-ray recognition system is used to determine whether the particle size of each particle on the belt conveyor is smaller than the preset lower limit particle size threshold of the feed material. If there is such a suspected initial adhesion, then within the period of the target time interval when the initial adhesion next enters the X-ray recognition system determined according to the total length of the belt, the belt speed and the belt speed fluctuation of the belt conveyor, it is determined again whether there is a second particle similar to the initial adhesion at the corresponding position of the initial adhesion on the belt. By using the period of the above-mentioned target time interval and through the process of these two judgments, the adhesions attached to the belt in the belt conveyor can be more accurately identified, thereby improving the recognition accuracy of particles attached to the belt of the belt conveyor.

[0067] The above steps are described in detail below.

[0068] In some embodiments, before step S110, the method may further include the following steps:

[0069] The belt on the belt conveyor is corrected, and the intensity fluctuation range of different points of the belt after correction is obtained; the parameters are adjusted according to the intensity fluctuation range of different points to identify particles smaller than the preset minimum particle size.

[0070] like Figure 2 As shown, the clean belt is corrected, the intensity fluctuation range of different points after correction is recorded, and the parameters are adjusted to increase the sensitivity of object recognition, thereby increasing the recognition system's ability to recognize objects with small particle size and small radiation absorption amplitude.

[0071] In some embodiments, after step S140, the method may further include the following steps:

[0072] The target recognition process entering the target time interval is determined as the first round of judgment process; if a third particle identical to the initial adhesion is detected before the initial adhesion enters the time period corresponding to the first round of judgment process, the third particle is determined as a contaminated particle on the identification light path, and it is determined that the contaminated particle is cleared and an alarm for light path contamination is issued.

[0073] The time interval in the above step S140 is set, and the re-identification after entering this interval is recorded as the first round of judgment process. If the same object is found before the object enters the time period corresponding to the first round of judgment process, the object may be contamination on the identification light path, which is deleted from the suspected adhesions and an alarm of light path contamination is issued, thereby improving the timeliness of processing light path contamination.

[0074] In some embodiments, after determining the target identification process entering the target time interval as the first round of judgment process, the method may further include the following steps:

[0075] If there are non-similar particles that are not similar to the initial adhesion at the corresponding position of the initial adhesion on the belt within the time period corresponding to the first round of judgment process, it is determined to wait for the second round of judgment process after the first round of judgment process, and the judgment round of each initial adhesion is set.

[0076] For example, if there are non-similar particles at this position during the time period corresponding to the first round of judgment process, such as other particles normally fed, then you can wait for the second round of judgment process. To increase accuracy and flexibility, you can set the judgment round for each suspected adhesion. In this way, the accuracy and flexibility of identifying adhesions on the belt conveyor are increased.

[0077] In some embodiments, after step S160, the method may further include the following steps: maneuvering the cleaning device to the corresponding position of the final adhesion on the belt through the data processing end; and clearing the final adhesion through the cleaning device based on a preset blowing time.

[0078] like Figure 2 As shown in the figure, the adhesion is cleaned by the intelligent powerful cleaning device. After receiving the location information of the adhesion, the processing center will mobilize the intelligent powerful cleaning device to the specified position (or selectively open the cleaning point at the corresponding position), and perform the cleaning work according to the set spraying time. In this way, the removal efficiency of the final adhesion is improved.

[0079] In some embodiments, the cleaning equipment includes a rubber scraper, a brush, and an intelligent cleaning device;

[0080] The intelligent cleaning device is equipped with a blowing unit and multiple fixed cleaning units. The fixed cleaning units are used to start the corresponding blowing units according to the particle position and movement time; alternatively, the intelligent cleaning device uses a slide rail sliding adjustment method to control a single cleaning unit to clean a fixed position.

[0081] Exemplarily, the above-mentioned cleaning equipment is composed of a traditional whole cleaner and an intelligent cleaning device. The traditional cleaner is often composed of a rubber scraper, a brush, etc. There are two options for the intelligent cleaning device: one is to install multiple fixed cleaning units, and according to the position and movement time of the object, the corresponding blowing unit is turned on at a fixed time to achieve intelligent cleaning; the other is to adopt a slide rail type, in which a single cleaning unit is responsible for a fixed area, and a sliding adjustment method is used to achieve cleaning of a fixed position. In this way, the utilization rate of the cleaning equipment is improved, thereby improving its effect on removing adhesions on the belt conveyor.

[0082] Figure 3 A schematic diagram of the structure of a device for processing adhesions on a belt conveyor is provided. Figure 3 As shown, the device 300 for processing adhesions on a belt conveyor comprises:

[0083] An acquisition module 301 is used to acquire 3-ray image information on the belt conveyor during the sorting process through a 3-ray recognition system, and determine the particle size of each particle on the belt conveyor according to the 3-ray image information;

[0084] The first judgment module 302 is used to judge whether the particle size is smaller than a preset lower limit particle size threshold of the feed material;

[0085] A first determination module 303 is used to determine the first particle smaller than the preset feed lower limit particle size threshold as an initial adhesion if the particle size is smaller than the preset feed lower limit particle size threshold;

[0086] A second determination module 304 is used to determine a target time interval for the initial adhesion to enter the three-ray recognition system next time according to the total belt length, belt speed and belt speed fluctuation of the belt conveyor;

[0087] A second judgment module 305 is used to judge again whether there are second particles similar to the initial adhesion at the corresponding position of the initial adhesion on the belt within the period of the target time interval;

[0088] The sending module 306 is used to determine the second particle as the final adhesion if there is a second particle similar to the initial adhesion, and send the information of the final adhesion to the data processing end; wherein the information of the final adhesion includes the corresponding position of the final adhesion on the belt.
