A heat treatment system may include a heat treatment furnace configured to heat treat a material in a saggar, the saggar including a saggar body and a lid; a lid removing device configured to remove the lid from the saggar; a body conveyor configured to convey the saggar body; a lid conveyor configured to convey the lid; a recovery device configured to recover the material from the saggar body; a supply device configured to supply a non-heat-treated material to the saggar body; and a lid attaching device configured to attach the lid to the saggar body. A conveying time for the lid to be conveyed from an entrance to an exit of a conveying path of the lid conveyor may be shorter than a conveying time for the saggar body to be conveyed from an entrance to an exit of a conveying path of the body conveyor.

A calcination unit able to decarbonate raw materials intended for clinker production, the unit including: a main duct in which the raw materials circulate according to a first movement direction, the raw materials being calcined in the main duct; a solid fuel supply duct opening onto the main duct via a fuel outlet, the solid fuel moving according to a second movement direction; a retaining device located in the main duct and arranged opposite the solid fuel outlet so that the solid fuel arriving in the main duct via the fuel outlet passes through the retaining device.

Disclosed are an unblocking apparatus for a furnace discharging pipe and a use method. The unblocking apparatus includes a rail, a rail car that may move along the rail, an unblocking drive mechanism arranged on the rail car, a heat-unblocking component, a cold-unblocking component, and a material receiving component that is used to receive a blocking material in the discharging pipe, and a drive end of the unblocking drive mechanism is detachably connected with one end of the heat-unblocking component and the cold-unblocking component respectively. The present application effectively handles different blockage situations of the furnace discharging pipe by connecting the unblocking drive mechanism with an unblocking rod capable of heat-unblocking and a drilling rod capable of cold-unblocking, thereby two modes of heat-unblocking and cold-unblocking are performed on the furnace discharging pipe; and the discharging pipe may be unblocked by a remote operation.

A carburizing device includes a furnace body that performs heat treatment on a treatment object to perform carburization treatment on the treatment object, in which: a heater configured to perform heat treatment on the treatment object is provided upright in a vertical direction within the furnace body; a gas supply section configured to supply a gas for burnout toward the heater is provided at a lower end part of the heater; the heater is inserted through a protective tube provided upright in the vertical direction; and the gas supply section is configured to supply the gas for burnout to between the protective tube and the heater.

This disclosure provides a waste battery thermal desorption treatment system. The waste battery thermal desorption treatment system includes: a rotary kiln, having a feed port, thermal desorption cavity, heating cavity, discharge port, and first exhaust port; a dust removal apparatus, including a housing with a gas inlet port and a second exhaust port, and a dust removal structure disposed in the housing configured to collect impurities in a gas exhausted from the first exhaust port; a condenser, in communication with the second exhaust port, to condense an electrolyte constituent; and an adsorption column having a defluorination agent for dry defluorination on remaining constituents in the gaseous exhaust. This disclosure resolves the problem of low recycling efficiency of waste lithium batteries in the prior art.

A gripping tool for removing a heat exchanger plate from a furnace wall, the gripping tool including a base having a mechanical attachment device for releasably fixing to a tool end of a boom, and a gripping assembly carriage equipped with at least a fork extending, when in use, substantially horizontally from the gripping assembly carriage. The gripping assembly carriage further includes a clamp assembly having a clamp arm equipped with at least a clamp pad, wherein said clamp arm extends substantially in the direction of the at least one fork and is movable towards and away from the at least one fork for clamping a heat exchanger plate between the fork and the clamp pad.

An apparatus for shaving a tap hole surface of a blast furnace or the like wherein efficiency can be improved, and a worker can be freed from physically burdensome work in the vicinity of the lower furnace wall of a blast furnace under high temperature. The apparatus includes a surface shaving unit having smoothing bits, and a rotating mechanism unit that, when the surface shaving unit is pressed against the tap hole surface, rotates the surface shaving unit, by utilizing the pressing force, by a predetermined angle in a predetermined direction substantially parallel to the surface, and holds the surface shaving unit at the rotated position. The rotating mechanism unit eliminates the need for work such that every time a conventional surface shaving unit is separated from the tap hole surface after being pressed against the surface, a worker manually rotates the surface shaving unit by a predetermined angle.

A method for detecting a cleaning need of a commercial cooking appliance with at least one cooking surface. The method includes the steps of capturing at least one image of at least a part of the cooking surface and/or at least a part of a cooking product, comparing the captured image of the part of the cooking surface with a prestored reference image of a contaminated cooking surface requiring cleaning and/or of the captured image of the part of the cooking product with a prestored reference image of the cooking product in a cooking status indicating a need for cleaning the cooking surface, and deciding, based on the result of the comparison, whether a cleaning is needed. A further aspect relates to a quality management monitoring system as well as a commercial appliance with a quality management monitoring system.
