The invention relates to the technical field of machine tools, in particular to a wire-cut electrical discharge machining device. The device comprises a machine body, a wire passing mechanism, a supporting column, a water feeding mechanism, a fixing mechanism, a metal wire, a mounting mechanism, supporting plates, an adjusting mechanism, a limiting mechanism and a cleaning mechanism, the metal wire rotates on the side wall of the wire passing mechanism, and the water feeding mechanism is installed at the bottom end of the wire passing mechanism. According to the device, when the metal is cut,the liquid in the water feeding mechanism converges into huge water flow and flows to the metal surface along with the metal wire, the melted metal is quickly washed away, attachments on the metal wire are reduced, the cleaning mechanism is installed at the bottom end of the wire passing mechanism, the metal wire moves up and down in a zigzag mode inside the cleaning mechanism, so that the surfaceof the metal wire is fully contacted with the interior of the cleaning mechanism to clean up metal attachments on the surface of the metal wire; the water feeding mechanism and the cleaning mechanismare located on the top end of the mounting mechanism, the liquid and the metal fragments directly fall on the v-shaped top surface of the mounting mechanism, so that the metal fragments can be conveniently washed away by the liquid.

The invention provides a shaking oxygenation and centrifugal sand removal ruditapes philippinarum conditioning device and a using method, relates to the field of aquatic product cleaning machines, andsolves the problem that sand in the ruditapes philippinarum is not easy to spit out, and cleaning is inconvenient. The shaking oxygenation and centrifugal sand removal ruditapes philippinarum conditioning device comprises a conditioning and cleaning tank; the top part of the conditioning and cleaning tank is stuck to the bottom part of an erecting top plate through electric hydraulic pushing poles; a conditioning bag box is arranged in the conditioning and cleaning tank; and the bottom part of the conditioning and cleaning tank is provided with a bubble sand separating mechanism. According tothe shaking oxygenation and centrifugal sand removal ruditapes philippinarum conditioning device, a top motor controls the conditioning bag box to move vertically in the conditioning and cleaning tank to shake the ruditapes philippinarum placed in the conditioning bag box to promote the ruditapes philippinarum to spit out the inside sand thoroughly; and meanwhile, an electric heating tube heats cleaning water filled in the conditioning and cleaning tank, and shaking of the conditioning bag box promotes the temperature of the cleaning water to be uniform, and with the combination of the heating method and shaking method, the conditioning effect of the ruditapes philippinarum is better.

The invention relates to the field of electrofluid jet printing equipment, in particular to a piezoelectric type integrated spray head used for electrofluid jet printing. The piezoelectric type integrated spray head comprises an outer bracket, a piezoelectric structure, a spray head, a lower electrode supporting ring and a lower electrode ring, wherein the piezoelectric structure is positioned above the spray head; an upper electrode is arranged on the upper part of the spray head; the lower electrode supporting ring and the lower electrode ring are sequentially arranged below the spray head; after the piezoelectric structure, the upper electrode and a lower electrode are electrified, electric fields are formed between the spray head and the lower electrode ring, so that a solution forms Taylor cones on the spray head. The piezoelectric type integrated spray head overcomes the defect that existing electric jet printing equipment cannot meet high-frequency spraying, can realize high-frequency high-resolution printing; and the lower electrode is integrated to the spray head end, so that the whole jet printing system is more flexible, and a base plate with a complex shape can be used to print. The piezoelectric type integrated spray head further has the advantages of being simple in structure, low in manufacturing cost, suitable for large-scale production and the like.
