The present application relates to a kind of modular molten salt loading and storage system, including vertical support structure rack, normal temperature electrical equipment group and high temperature molten salt equipment group are physically separated by isolation fence and integrated in it;High temperature molten salt equipment group includes molten salt storage tank and molten salt pipeline connected with molten salt storage tank;Molten salt pipeline includes molten salt loading pipe, molten salt loading pipe has upward inclination relative to horizontal plane, to realize the self-weight backflow of molten salt;The middle section of molten salt loading pipe is connected with molten salt isolation valve, and molten salt isolation valve and normal temperature electrical equipment group are cooperated to realize the on-off control of molten salt loading pipe.The present application effectively avoids the thermal influence of high temperature environment on normal temperature electrical equipment by isolation fence, and the integrated design of overall modularization integrates the core equipment of molten salt loading and storage into one, discards the traditional dispersed equipment arrangement and installation mode, greatly simplifies the field construction process, reduces installation period, also makes the debugging, maintenance and overhaul of system more convenient.

The utility model discloses a machining center chip flushing device belongs to machining technical field, including the organism, the bottom wall in the organism is installed with the reflux tank, is provided with the flushing mechanism between the reflux tank and the organism, the inside fixed waste tank of organism, the top symmetrical of waste tank is provided with the flow guide plate, one side symmetrical of organism is installed with the motor, and the motor output shaft is fixed with the deslag screw rod, and the deslag screw rod is through to the inside of waste tank, is provided with the cleaning mechanism between the deslag screw rod and the organism, and the bottom fixed of waste tank one end is provided with the screen frame. The utility model discloses through the hydraulic cylinder drive push frame automatic discharge screen frame in the accumulation chip, avoid the chip to jam the screen, lead to the washing liquid reflux not to be smooth, solve the waste tank waterlogging overflow problem, improve the washing liquid circulation use efficiency, need not manual frequent cleaning screen frame, both promote the chip processing automation degree, and guarantee the washing liquid reflux smooth, avoid the machine tool workstation pollution, reduce the maintenance cost.

This utility model discloses a cyclone separator for a biomass circulating fluidized bed boiler, comprising a flue gas inlet section, a gas-solid two-phase separation section connected to the flue gas inlet section, a flue gas outlet section connected to the top and bottom of the gas-solid two-phase separation section respectively, and a solid return section. The solid return section includes multiple coaxially connected and fixedly connected solid return straight sections and multiple solid return conical sections, which are arranged at intervals in the vertical direction. Flue gas flows in from the flue gas inlet section, rotates along the inner wall of the gas-solid two-phase separation section, and achieves gas-solid two-phase separation through centrifugal force. The gas phase flows out through the flue gas outlet section, and the solid phase is returned from top to bottom through the solid return section. Through segmented and optimized solid return path and gas-solid separation flow field, the intermittent blockage problem caused by alkali metal adhesion in traditional cyclone separators is solved, avoiding forced boiler load reduction or shutdown. It is especially suitable for biomass combustion scenarios with complex fuel types and variable ash composition.

The utility model discloses a gravity return hinge device belongs to door body hinge field, including upper hinge, pin shaft, first shaft sleeve, second shaft sleeve and lower hinge, upper hinge is integral type structure, is constituted by upper hinge board, sleeve and pivot, upper hinge board bottom surface and sleeve top end vertical, pivot is located in the sleeve, and with sleeve coaxial arrangement, pivot top end and upper hinge board vertical, bottom end and stretch out sleeve, be equipped with first through -hole and second through -hole on the sleeve wall, be equipped with third through -hole on the pivot, and three through -holes coaxial arrangement, pin shaft passes first through -hole, third through -hole and second through -hole in proper order, and with three through -hole interference fit, first shaft sleeve rotatable sleeve on pin shaft between first through -hole and third through -hole section, second shaft sleeve rotatable sleeve on pin shaft between second through -hole and third through -hole section. Pin shaft and upper hinge jointly bear the weight of door body, greatly improved the bearing strength to door body, has promoted the service life of hinge.
