The utility model discloses a recovery device for cement processing, which comprises a main body frame, a transportation turnover mechanism, a loading bucket clamping mechanism and a clamping auxiliary mechanism, the transportation turnover mechanism comprises a main shaft, a driven shaft, a main tooth, a driven tooth, a transmission chain and a turnover bucket, the loading bucket clamping mechanism comprises a clamping pipe, a clamping rod, a rotary sleeve, a rotary pushing block, an annular groove, a pushing block groove, a spring rod and a longitudinal pressing groove, the transportation turnover mechanism can ensure that the turnover bucket is driven by a transmission chain to stably operate, and the phenomenon of jamming or instability caused by unsmooth mechanical transmission is avoided; the loading bucket clamping mechanism can ensure that the assembling and disassembling process of the overturning bucket is simple and reliable, the rotary pushing block can be fixed in the clamping groove through the help of the spring rod, loosening is avoided, and the safety and stability of the device are improved.

The present application relates to thin film deposition equipment technical field, disclose a shower head and its processing method, the shower head includes: cover plate has the through hole, the through hole includes first hole section and second hole section;Spray plate is provided with connecting column, connecting column includes thread section and base section;Connecting sleeve, including sleeve, sleeve is matched on the outside of thread section;First sealing structure, between the sleeve and the one end of thread section away from base section, the first sealing structure seals the sleeve and thread section.The present application is matched by the sleeve and connecting column thread connection, realize the connection of cover plate and spray plate, the consistency of thread cooperation is higher than welding, can effectively improve the connection precision, in addition, realize the process of connection without using welding and so on heating means, therefore can avoid the deformation of connecting column and so on connecting structure, in addition, still set up the first sealing structure, the first sealing structure can guarantee the sealing performance between connecting sleeve and connecting column, simple structure, convenient operation.

The utility model relates to a valve, specifically disclose a unloading valve at least including valve body, valve rod, diaphragm mechanism, auxiliary spring, adjusting cylinder, pressure regulating spring, top plug and adjusting plug. Among them, the lower diaphragm fixed base includes the horizontal extension diaphragm fixed section one and the axial extension valve body connecting section, the diaphragm fixed section one and valve body connecting section between smooth transition connection, the upper end of valve body is provided with the outer ring groove of with the inner chamber of valve body connecting section adaptation, the axial height of outer ring groove with the axial height of valve body connecting section adaptation, the radial depth of outer ring groove with the thickness of lower diaphragm fixed base adaptation, valve body connecting section is set up on outer ring groove and is fixed through welding. In the utility model, based on the cooperation between valve body connecting section and outer ring groove on the valve body of lower diaphragm fixed base, a longer welding lap joint surface is formed, which has higher reliability under high pressure environment, and the service life of the unloading valve is longer.
