The utility model provides a kind of adjustable filter outer frame, including outer frame, outer frame includes a pair of left and right sides oppositely arranged frame body, connecting piece is arranged between two side frame bodies relative upper and lower sides, connecting piece is detachably connected with frame body and encloses outer frame;Each frame body includes the bottom plate extending along length direction, the two sides of bottom plate length direction are bent to form fixed plate respectively, fixed plate is equipped with first connecting hole, air hole and scale, connecting piece is used to connect the upper and lower sides of air filter medium relative;Through scale and the design of cuttable frame body, the size of air filter can be adjusted according to installation environment, improve versatility, avoid the installation difficulty or resource waste caused by size inconsistency, can be applicable to a variety of installation environments, reduce the idle and inventory of multi-size customization, and improve the efficiency of air filtration and outer frame practicality.

The utility model relates to food preservation technical field, specifically disclose a pet food refrigeration box, including box, the wet grain storage cavity and dry grain storage cavity are arranged to box upside and downside, the first thermoelectric refrigeration assembly and second thermoelectric refrigeration assembly that are used respectively to carry out refrigeration to wet grain storage cavity and dry grain storage cavity are built -in to box, the refrigerating capacity of first thermoelectric refrigeration assembly is greater than the refrigerating capacity of second thermoelectric refrigeration assembly, and dry grain storage cavity top is equipped with the sterilization subassembly of the door closing time start, the pet food refrigeration box of the application divides wet grain storage cavity and dry grain storage cavity and carries out independent refrigeration temperature control to be used respectively for storing pet wet grain and pet dry grain, reduces the risk of corruption, avoids the loss of nutrition, secondly, the pet food refrigeration box of the application still sets up sterilization subassembly in dry grain storage cavity, and sterilization subassembly starts when the door closes, can effectively reduce microbial pollution, improves pet food hygiene safety.

This invention discloses a method for hydrogen production, storage, and refueling, comprising: S1, electrolyzing water to produce oxygen and hydrogen, with waste heat stored in a heat storage device; S2, the produced oxygen entering an oxygen storage tank, with waste heat stored in the heat storage device; S3, the produced hydrogen entering a first solid hydrogen storage material, with waste heat stored in the heat storage device; S4, when the first solid hydrogen storage material is full, hydrogen enters a second solid hydrogen storage material, with waste heat transferred to the first solid hydrogen storage material, enabling the first solid hydrogen storage material to refuel at a hydrogen refueling station; S5, when the second solid hydrogen storage material is full, hydrogen re-enters the first solid hydrogen storage material, with waste heat transferred to the second solid hydrogen storage material, enabling the second solid hydrogen storage material to refuel at a hydrogen refueling station; S6, repeating steps S4 and S5, until the reaction stops, the heat storage device transfers heat to the first and second solid hydrogen storage materials, causing them to release remaining hydrogen into the hydrogen refueling station. This invention achieves highly efficient hydrogen storage and refueling operations.
