Adjustable vibrating mechanism of iron alloy granule-casting machine

Номер: CN103056350A
Автор: Cui Yuchun, Liu Weiguo
Принадлежит:

The invention belongs to the technical field of alloy ingot continuous production and in particular relates to an adjustable vibrating mechanism of an iron alloy granule-casting machine. The adjustable vibrating mechanism comprises a driving vibrating device, a spring bed assembly and a vibrating plate connected with the spring bed assembly. The adjustable vibrating mechanism is characterized in that the driving vibrating device comprises a driving motor, a driving gear shaft, a driving gear, weighting blocks I arranged at two ends of the driving gear shaft, a connecting bracket I, a driven gear shaft, a driven gear engaged with the driving gear, weighting blocks II arranged at two ends of the driven gear shaft and a connecting bracket II; both the connecting bracket I and the connecting bracket II are connected with a vibrating box body; and the vibrating box body is connected with the spring bed assembly. With the adoption of the double-gear drive manner, the synchronous rotation of the ...

The invention relates to a process for improving a universal type plasticizer for the chemical industry, particularly to a process for improving a production device of dioctyl phthalate. The process is characterized by comprising the steps that solid flaky phthalic anhydride and capryl alcohol are added simultaneously from the top of a phthalic anhydride melting kettle, phthalic anhydride and capryl alcohol are fed according to a molar ratio of (0.8-1.0):1, the reaction temperature ranges between 135 DEG C and 155 DEG C, and the reaction time ranges between 2 hours and 2.5 hours. The process has the advantages that a process medium inside the improved phthalic anhydride melting kettle flows smoothly in the device and pipelines, no blocking phenomena exist again, and the continuous working time for operation can be improved; and the improved phthalic anhydride melting kettle can melt phthalic anhydride and also can generate unit esters, the technological process is simplified, the one-time ...

Coated internal combustion engine cylinder sealing liner plate

Номер: CN102797588A
Автор: Cui Yuchun, Cui Yuguang
Принадлежит:

The invention provides a coated internal combustion engine cylinder sealing liner plate, which comprises a substrate, wherein the substrate is provided with a cylinder port and a through hole, and is characterized in that: parts of the substrate surrounding the cylinder port are provided with annular convex surfaces; other parts of the substrate are planes; the planar parts of the substrate are provided with plastic coatings; and the through hole linearly passes through the plastic coating and the substrate. Compared with the prior art, the coated internal combustion engine cylinder sealing liner plate has the positive effects: the liner plate has a coated structure, plastic coatings are attached to all parts except the parts of the substrate surrounding the cylinder port which are designed into annular convex surfaces on the substrate, the periphery of the through hole is positioned on the same plane, and a sealing ring protruding outwards is eliminated, so that the sealing performance ...
