and the intelligent filter pressing controller is internally provided with an intelligent filter pressing control algorithm and is used for collecting data of the AI filtrate video monitoring system and the filtrate discharge flow monitoring device and bringing a plurality of filter presses, feeding conveying equipment and downstream conveying equipment into control of the intelligent filter pressing control algorithm.
According to the technical scheme, the system for queuing, processing and discharging based on the filter press overall can realize an automatic and intelligent coal slime water treatment process through the cooperative work of all the components, and comprises the monitoring of the filter press, the coordination of feeding and downstream equipment and the intelligent control of the whole system. Wherein: the filter press is a core part of the system, an inlet of the filter press is connected with the feeding conveying equipment and is used for receiving the coal slime water to be treated, an outlet of the filter press is connected with the downstream conveying equipment and is used for conveying the treated coal slime to the downstream equipment; the feeding and conveying equipment has the functions of conveying the coal slime water to be filtered to the filter press, wherein an inlet is connected with a source of the coal slime water, and an outlet is connected with an inlet of the filter press so as to ensure that the coal slime water can smoothly enter the filter press; the downstream conveying equipment has the functions of discharging the coal slime pressed by the filter press, wherein an inlet is connected with an outlet of the filter press so as to receive the processed coal slime, and then the processed coal slime is conveyed to the next processing equipment or storage facility; the AI filtrate video monitoring system is arranged above each filter press and is used for monitoring the real-time flowing condition of the filtrate, and the flowing state of the filtrate can be intuitively observed through video monitoring, so that the running state of the filter press is judged; the filtrate discharge flow monitoring device is arranged on a discharge pipeline of each filter press and is used for monitoring the real-time flow of the filter press, and the treatment state of the filter press can be known by measuring and monitoring the flow; the intelligent filter pressing controller is a control center of the system, is internally provided with an intelligent filter pressing control algorithm and is responsible for collecting data of an AI filtrate video monitoring system and a filtrate discharge flow monitoring device, a plurality of filter presses, feeding conveying equipment and downstream conveying equipment are brought into control of the intelligent filter pressing control algorithm, and the running efficiency and the processing quality of the whole system can be optimized through intelligent control.
The idea of the invention is explained below in connection with specific cases.
For example, in the case of five filter presses operating simultaneously, when filter press one meets the discharge conditions, it will enter the queuing system. At this time, the filter press No. two and No. three are waiting in line, the filter press No. four is unloading, and the filter press No. five is performing the pressing process. At this time, there are two different processing principles that can be considered:
the first is the sequencing principle. In this case, when the filter press No. four has completed discharging, the filter press No. two, which was first queued, will preferentially enter the discharging process, followed by the filter press No. three and filter press No. one. This principle is based mainly on the queue order, i.e. first come first served principle, as shown in fig. 2.
The second is the efficiency priority principle. In this case, a filter press with high operation efficiency is prioritized. Specifically, when the first filter press enters the queuing system, it will automatically line up before the second and third filter presses. When the third filter press finishes discharging, the first filter press starts discharging. The purpose of this principle is to increase the efficiency of the overall system by ensuring a high efficiency filter press operation with priority, as shown in figure 3.
In addition, the efficiency priority principle and the sequencing principle can be used in a crossed mode. In particular, one or more filter presses may be designed as efficiency-first devices. If there is no efficiency priority device in the queuing system, then the sequencing principle is performed, as shown in FIG. 4.
By adopting the method, the following aims can be achieved:
first, system performance is improved: the whole process intelligent monitoring and automatic operation of the operation state of the filter press are realized, so that the stability and reliability of the system can be greatly improved, and meanwhile, the intervention of manual operation is reduced, thereby improving the performance of the system.
Secondly, the operation efficiency is improved: by the automatic queuing and automatic discharging adjustment of the system, seamless connection of discharging of the filter press can be realized. In addition, the filter press with highest operation efficiency can be ensured to obtain more operation time through intelligent queuing, and the operation efficiency of the whole system can be effectively improved. This approach is expected to increase the system operating efficiency by more than 20%.
Finally, labor intensity is reduced. Because the site is not required to be inspected manually, the labor intensity of site personnel can be greatly reduced, and meanwhile, the interference of human factors is reduced, so that the stability and the reliability of the system are improved.
Although the present invention has been described in detail by way of preferred embodiments with reference to the accompanying drawings, the present invention is not limited thereto. Various equivalent modifications and substitutions may be made in the embodiments of the present invention by those skilled in the art without departing from the spirit and scope of the present invention, and it is intended that all such modifications and substitutions be within the scope of the present invention/be within the scope of the present invention as defined by the appended claims.

The method for queuing, processing and unloading based on filter press overall as claimed in claim 1, wherein in the step S2, the processing principle of queuing, processing and unloading is an efficiency priority principle, that is, according to the consideration of the operating efficiency of the filter press, the operating efficiency of a plurality of filter presses is analyzed, the queuing and unloading of the filter presses with high operating efficiency are preferentially considered, the operating time of the high-efficiency filter press is increased, and the overall operating efficiency of the system is improved.
7. The method for queuing discharge processing based on filter press assembly according to claim 5 or 6, wherein in step S2, the processing principle of queuing discharge processing is simultaneously compatible, i.e. the first-in first-out principle and the efficiency priority principle are executed in a crossing manner, one or more devices with efficiency priority are selected, and if the devices with efficiency priority are not available in the queuing system, the first-in first-out principle is executed in the queuing.
8. A system for queuing, processing and unloading based on a filter press, which adopts the method for queuing, processing and unloading based on the filter press as claimed in any one of claims 1-7, and is characterized by comprising the following components:
the filter press is used for treating slime water, the inlet of the filter press is connected with the feeding conveying equipment, and the outlet of the filter press is connected with the downstream conveying equipment;
the feeding and conveying equipment is used for conveying the coal slime water to be subjected to filter pressing to the filter press;
the downstream conveying equipment is used for unloading the coal slime pressed by the filter press;
the AI filtrate video monitoring system is arranged above each filter press and is used for monitoring the real-time flowing condition of filtrate;
the filtrate discharge flow monitoring device is arranged on a discharge pipeline of each filter press and is used for monitoring the real-time flow of the filter press;
