A chain pitch measurement method of scraper conveyor based on speckle structured light is proposed to improve security and automation. Two speckle structured light cameras are used to collect point clouds on the chain surface from different angles, and the point clouds are transformed to a common reference coordinate system by rotating and translation matrix with calibration. The chain point cloud is preprocessed by plane model segmentation and radius filtering, the main direction of the point cloud is calculated by point cloud principal component analysis, the key points of measurement are detected by neighbors within radius search of the point cloud, and finally, the chain pitch is solved by Euclidean distance. The actual measurement error of the measurement method proposed in this paper is less than 2%, which can meet the needs of coal mining.

“…Conveyors are essential equipment in mining operations because they can efficiently and quickly transport materials from one location to another. Therefore, the use of conveyors in the mining industry is becoming more widespread and has become a commonly used tool (Mu et al, 2020). Conveyors have high transport efficiency and strong transport capacity (He et al, 2017).…”

The tail-shaft is one of the components of the apron feeder on the conveyor. Its role is quite significant, as it includes a take-up system to adjust the tension and slackness of the chain on the sprocket against the Lamella. Based on observations in a mining industry, it was found that tail-shaft damage frequently occurs, likely due to the excess load carried by the conveyor. Therefore, researchers were interested in investigating the maximum capacity of the tail-shaft. The research was conducted using the Finite Element Analysis method with Solidworks Research License. The material used for the tail-shaft is DIN 1.0038. Torque variations tested on the tail-shaft were from 42,000 N.m to 58,000 N.m. Based on the simulation results, the maximum torque that the tail-shaft can withstand is 54,000 N.m with a safety factor value greater than 1, whereas when given a torque of 58,000 N.m, the safety factor value is less than 1. The tail-shaft experiences a maximum stress that exceeds the yield strength of DIN 1.0038 material, which can cause damage to the material. The initial damage appears at the end of the shaft due to the use of chamfer. This is known based on the results of simulations that have been conducted.

Scheduling of Batch Operation for a Wastewater Treatment Plant under Time-of-Use Electricity Pricing

High operating cost caused by electric energy consumption is a common problem challenging many municipal wastewater treatment plants (WWTPs). Due to the characteristics of intermittent inflow and aeration, WWTPs using sequencing batch reactor technology and its variants can be managed to relieve operating cost through taking advantage of time-of-use electricity pricing. However, little attention has been paid to the scheduling of treatment processes in the context of WWTPs. In this paper, a novel mixed-integer linear programming model is established for scheduling the batch operation of a WWTP under time-of-use electricity pricing, which considers constraints arising from task allocation, processing sequence, and processing duration. The modeling method is developed from the event-based continuous-time approach. The start time and end time of each treatment task are optimized to shift electricity consumption from peak hours to off-peak hours to the greatest extent, thus minimizing electricity cost. A case study demonstrates that the proposed model can quickly generate precise operational plans for the investigated WWTP. By implementing the optimum schedules, the WWTP can save on its electricity bill without changing the treatment capacity or the treatment process. The widening of peak and off-peak electricity pricing gap is favorable for the proposed model to display a more significant effect in reducing electricity cost.
