Tianchuang robot unlocks a new application scenario for intelligent inspection at Huaibei Mining and Coal Preparation Plant

Linhuan Coal Preparation Plant of Huaibei Mining Co., Ltd. is divided into two independent production plants in the east and west areas, and has six branch factories under its jurisdiction. It has an annual production capacity of 16 million tons. It is the largest centralized coking coal preparation plant in Asia.

In response to the inspection needs of the filter press production area of Linhuan Coal Preparation Plant and environmental characteristics such as noise and dust, Tianchuang Robot uses two sets of intelligent robots as the core to replace the daily inspection tasks of operation and maintenance personnel, effectively solving the problem of traditional manual inspections. Problems such as time-consuming and labor-intensive inspections and poor real-time performance achieve safe, efficient and precise production in the factory area and improve the efficiency and efficiency of inspection and operation.

    Customer Profile    

Linhuan Coal Preparation Plant is located in Suixi County, Huaibei City, Anhui Province. It is mainly responsible for discharging raw coal before selection. At present, the capacity of selected raw coal has reached 16.0Mt/a.

   Project Background    

The equipment area of the West Filter Press Plant of Linhuan Coal Preparation Plant consists of 10 filter presses, which is responsible for dehydrating and recycling fine coal slurry during coal processing and accelerating the processing of tailings coal.

    Business Challenges    

The filter press workshop area covers an area of about 1380m2. During the production process, it is necessary to always pay attention to the falling off of the filter plate and the damage of the filter cloth at the filtrate water collection tank when the filter press is unloaded. If abnormal conditions cannot be discovered in time and handled, it will cause greater safety hazards.

Filter press equipment will produce noise, dust, waste gas and other pollutants when working, posing certain personal hazards to operation and maintenance personnel. Traditional manual inspections are easily influenced by personal experience and subjective consciousness, and are restricted by monitoring methods, data recording, and data analysis. They are time-consuming, laborious, and have poor real-time performance.

    Solutions    

In response to the environmental and spatial characteristics, equipment distribution, and core point inspection content and process standard requirements, Tianchuang Robot deployed a set of T7-S wheeled lift arm robots and a set of T3-S hanging rail lift arm robots to cover the entire area and key monitoring equipment, and cooperated with communication base stations, workstations, charging stations, etc. to build a set of intelligent inspection solutions based on filter press equipment production scenarios for Linhuan Coal Preparation Plant. Under the conditions of not affecting the normal operation of on-site inspection system equipment and not blocking the passage of personnel, inspection without dead corners and blind spots can be realized, and the robot can take on duty for people.

The T7-S wheeled lifting arm robot is deployed on the ground and conducts cyclic inspections around 10 filter presses. It automatically identifies the value of the dual-pointer pressure gauge in the area and whether the high-pressure water pipes are leaking, intelligently identifies the water flow at the filtrate water collection tank, and determines whether There are impurities flowing out.

The T3-S rail-hanging lifting arm robot automatically walks along the track to the corresponding position when the filter press is unloading, and follows the filter press pulling plate trolley to detect the coal cake falling off between the two filter plates and the damage and leakage of the filter cloth in real time.

During different time periods when the filter press is feeding, two sets of robots cooperate to conduct inspections and automatically walk to the corresponding preset positions to perform work. When abnormal conditions occur during the linkage process, such as when the filter press is feeding and squeezing, the T7-S wheel lift arm robot inspects the filtrate water collection tank and identifies the color of the filtrate through Tianchuang Self-Research's intelligent AI vision algorithm to determine whether the filter cloth is damaged; When the filter press is unloading, the T3-S hanging rail lifting arm robot follows the pulling plate trolley to identify the coal slurry falling off between the two filter plates. Through remote monitoring and control by the inspection robot, automatic follow-up inspection of the filter press within the coverage area is realized.

    Value Effectiveness    

Precise and efficient equipment inspection

Tianchuang T7-S and T3-S two sets of robots fully replace manual labor to realize remote online precise monitoring of 46 inspection positions in the west factory area of the filter press and round-the-clock care of 10 equipment. They can promptly discover abnormal conditions and fault precursors during the equipment production process., improving the frequency and quality standards of inspections in the region.

Digital operation and maintenance management

Daily inspection data is classified and stored in real time, which facilitates the query, statistics, and judgment of fault problems, and reduces the cost and time of manually selecting useful variables. Allowing intelligence to replace manual labor, and allowing data to run errands to replace manual running, realizing the transformation of filter presses from "experience detection" to "data operation and maintenance" and from manual analysis to digital management.
