The present invention relates to the technical field of pressurized gas storage, and specifically to a high-pressure hydrogen storage tank container group, which includes a main frame, a gas tank, a measuring piece, and a closing mechanism; an operator first fixes gas tanks of different sizes to the main frame, and then uses the ventilation connecting pipe to exhaust gas, and at the same time, during the exhaust of one gas tank, uses other gas tanks to replenish gas, so as to ensure that the exhaust pressure fluctuates less, that is, when the pressure fails to meet the exhaust requirement, the exhaust port of the gas tank with insufficient pressure is blocked, and the above operations are repeated in sequence to release the pressure; the equipment has a simple structure, effectively realizes continuous exhaust of gas tanks of different sizes, and can block the gas tank with insufficient exhaust pressure, has good practicality and economy, and is beneficial to the promotion and use of the equipment.

A PB15 inlet cigarette pack channel fast switching device and method, device: the conversion channel is connected to the inlet cigarette pack conveyor belt and the auxiliary conveyor belt or the main conveyor belt under the control of the conversion cylinder; the core controller is respectively connected to the PB15 cigarette pack storage, the blocking trigger detector, the conversion position detector, the blocking position detector, the upstream machine speed signal, the conversion electromagnetic reversing valve, the blocking electromagnetic reversing valve, the PARKER servo controller, the inverter 1 and the inverter 2, the PARKER servo controller is connected to the cigarette pack conveyor belt servo motor, the inverter 1 is connected to the main conveyor belt motor, and the inverter 2 is connected to the auxiliary conveyor belt motor. Method: switch after the PB15 cigarette pack storage fails; block the conversion channel by blocking the cylinder; change the position of the conversion channel; block the conversion channel again; change the position of the conversion channel again; restore the operating state. The device and method can realize the rapid conversion of the cigarette pack conversion channel without stopping the upstream and downstream equipment, and its reliability is high.

The utility model relates to the technical field of stirrer, concretely to a stirring head quick replacement structure, including electric mixer body, electric mixer body left end is connected with the stirring head, the electric mixer body outer surface left end is installed with auxiliary mechanism, the auxiliary mechanism includes auxiliary cover, the auxiliary ring of welding in auxiliary cover left end and the limiting frame of welding in auxiliary ring right side surface, the limiting frame inside is provided with the limiting block, when needing to replace the stirring head, through the right movement of the auxiliary cover of pushing, make the auxiliary ring drive the right movement of sliding connecting block, make the limiting insertion rod can leave the limiting mechanism, then through the limiting groove cooperation limiting block will fix the position of auxiliary cover, can fix the position of sliding connecting block, can conveniently control limiting mechanism to replace the stirring head subsequently, through auxiliary mechanism makes the user can conveniently synchronous control both sides' locking mechanism, can more quickly replace the stirring head.

The invention relates to the technical field of hydrogen metallurgy, and discloses a hydrogen-based shaft furnace carbon dioxide utilization process which comprises a gas treatment tower system, a process gas loop, a process gas compressor, thermal oxide carbon capture equipment, carbon dioxide purification equipment and a storage tank. Carbon dioxide gas is introduced into an existing nitrogen pipeline (mainly a shaft furnace top nitrogen system, all loop purging nitrogen systems, a compressor gas seal nitrogen system and the like), after carbon dioxide is used for replacing original nitrogen, the carbon dioxide capable of being trapped in the circulation of the shaft furnace is increased, and the nitrogen which cannot be collected is reduced; the control and use of the whole gas loop are changed, the working efficiency of the hydrogen-based shaft furnace is improved, meanwhile, the tail gas combustion control of the reduction loop in the combustion control of the heating furnace is optimized, the nitrogen is added to assist the combustion control, and the safety SIS interlocking control is added.

Disclosed is a battery module with improved safety by suitably controlling venting of a gas generated inside the battery module. The battery module includes a cell assembly having at least one battery cell; a module case configured to accommodate the cell assembly in an inner space thereof and having a venting hole formed to discharge a venting gas generated from the cell assembly; and a venting unit provided to an outer side of the module case and configured to have a venting channel formed in at least one layer so that the venting gas discharged from the venting hole is introduced into the venting channel and is movable in the inner space.

The present invention discloses a water outlet joint, comprising a main body with a water passage, wherein the water outlet end of the water passage is connected with a nut; one end of the nut is located in the water passage, and the other end is located outside the main body; a connecting ring which can move and is connected with the water passage is arranged in the nut, and a reset spring is arranged in the connecting ring, and a plug assembly which can block the water outlet of the connecting ring is also arranged in the connecting ring. The joint solves the inherent shape of the water outlet switch and can realize the basic functions of the existing water outlet switch angle valve, is more convenient to operate, and omits the handle and valve core of the conventional angle valve, has lower cost, and caters to market demand.
