  • Patent number: 12018860
    Abstract: An integrated pressure condensing boiler is provided which relates to the technical field of boilers. The integrated pressure condensing boiler includes a pressure-bearing housing, a heat-exchange furnace arranged in the pressure-bearing housing, a combustion chamber communicating with the heat-exchange furnace and cooling tube groups fixed in the heat-exchange furnace. Heat-exchange medium flows from bottom to top in the pressure-bearing housing and in the cooling tube groups, and exchanges heat with high-temperature flue gas flowing from top to bottom in the heat-exchange furnace, thus achieving a counterflow heat exchanging. The heat-exchange furnace includes a multi-stage heat-exchange chamber with each heat-exchange chamber being cylindrical. The heat-exchange chambers are arranged in sequence from top to bottom to achieve a flue gas diffusing manner that high-temperature flue gas diffuses from center part to periphery and then gathers from periphery to center part.

  • Patent number: 11576420
    Abstract: An intelligent control system and method of thin plate dryer for cut tobacco are provided. The system includes a factor searching and screening unit, a control unit, an early warning unit. The control unit adopts a dual-model control method and establishes a process parameter control model and an energy balance model, the control unit calculates the moisture discharge opening value in real time according to the dual-model; the early warning unit is configured to connected with the control unit, and send out an alarm information based on early warning signal. The present disclosure is designed to transform the traditional control into intelligent precision control, improve product quality, reduce product differences between batches and build an intelligent early warning function.

  • Publication number: 20230026103
    Abstract: A cigarette device management system includes an information management module, and a maintenance prediction module, a device state acquisition module and a purchase statistics module which are in communication connection with it. The maintenance prediction module is built by an artificial neural network model and is configured to predict a failure interval. The device state acquisition module acquires a device operating parameter and an operating duration of the device in real time, and compares the device operating parameter with a safety parameter range. In accordance with the system, the maintenance timing of the device can be predicted, the purchase quantity of the spare part and the purchase timing of the spare part also can be predicted.

  • Patent number: 10573474
    Abstract: An intelligent integrated medium-voltage alternating current (AC) vacuum switchgear based on a flexible switching-closing technology comprises a controller (24), and a vacuum switching tube (1), an insulator (9), and an switching-closing mechanism connecting piece (15), which are connected in sequence. A microprocessor is built in an intelligent circuit (23); a travel sensor is fixed to a movable contact connecting rod (5), and directly detects a motion state of a movable contact (4) and acquires accurate motion parameters of the movable contact (4); switching-closing operating parameters are obtained by comprehensively calculating arc light intensity detected by an arc light transmitter (20) and a temperature measured by an infrared temperature measuring transmitter (22), such that the switching-closing performance of switching on and switching off a medium-voltage power grid is greatly improved, switching-closing time points are accurately controlled, and “flexible” switching-closing is achieved.
