2results about How to "Stable fluctuation" patented technology

This utility model relates to the field of odor control technology in pulp and paper mills, specifically disclosing an odor stabilizing and safety device for the pulp industry. It includes a pressure-stabilizing tank vertically positioned between the odor collection outlet and the odor treatment equipment. An odor inlet pipe is centrally located at the lower end of the pressure-stabilizing tank, extending into the tank. An emergency odor outlet pipe is centrally located at the upper end of the pressure-stabilizing tank. A sealing pipe is inverted and placed above the odor inlet pipe inside the pressure-stabilizing tank. The sealing pipe is sealed at the top and open at the bottom, with its top not contacting the upper end of the odor inlet pipe. The vertical height of the sealing pipe should be greater than the liquid level difference formed by the maximum and minimum odor pressures. A clean water inlet pipe is located at the lower part of one side of the pressure-stabilizing tank, and an overflow pipe is located in the middle of the other side. This utility model has multiple functions, including odor network pressure stabilization, safety valve, and prevention of odor overflow. One set of equipment integrates the functions of multiple devices, saving both investment costs and installation space.

This invention relates to a collaborative control method, apparatus, and equipment for a dual-track loading and feeding system, belonging to the field of railway loading technology. In this method, apparatus, and equipment, when the target car reaches a switching threshold during loading, it switches to the replenishment stage. By setting replenishment priority determination rules, the replenishment sequence of the two tracks is clearly defined, avoiding the problem of insufficient or accumulated material in the buffer bin caused by simultaneous replenishment, resolving the conflict problem of dual-track operations, and improving loading efficiency and accuracy. Furthermore, during the replenishment stage, a fuzzy PID fusion collaborative adjustment algorithm is used to adjust the parameters of multiple devices in a coordinated manner, stabilizing the material level in the buffer bin within the ideal range of 30%-50%. This ensures that coal flows directly into the chute with stable flow fluctuations, eliminating the need for secondary leveling, stabilizing the replenishment conditions, and significantly improving loading accuracy. Simultaneously, it avoids equipment overload caused by material accumulation and blockage, reduces the frequency of air cannon activation, and lowers equipment wear and energy consumption.
