The invention relates to a closed static pressure guide rail with a static pressure oil film clearance compensation function. The closed static pressure guide rail comprises a base, a carriage and a guide rail plate, wherein a plurality of piston devices are arranged on a movable guide rail on one side of the carriage; an oil film contact surface formed by a static pressure oil cavity is formed between the piston devices and the guide rail plate on the base. Due to the novel guide rail structure of the closed static pressure guide rail, the capacity for automatically adjusting a clearance of the static pressure guide rail is realized, and the clearance change, which is caused by thermal deformation, of the static pressure guide rail can be better compensated; the phenomenon that the static pressure guide rail is locked due to over-high temperature rise in a high-speed reciprocating motion is avoided; the safety of the static pressure guide rail is improved; a requirement on high-speed, high-precision and high-dynamic response to feeding of a sand wheel frame of a following grinding machine can be met.

The invention discloses an inlet diffuser of a hydrogenation reactor, comprising an inlet cone, a mounting plate and a spray cover; the inlet cone is a conical truncated body as a whole, the lower part is a flange-shaped flange, and the flange is provided with Guide column, swirl tubes are evenly distributed on the upper surface of the inlet cone, the upper part of the swirl tube is an inverted conical closing structure, and the lower part is a guide tube that plays a guiding role. There are rotating guide vanes in the inverted conical closing structure; the mounting plate is a circular The ring plate is sleeved on the outside of the inlet cone with its inner ring, and the guide column passes through its cylindrical hole, the guide column is sleeved with a spring, the upper end of the guide column is provided with a gasket and a nut, and both ends of the spring are fixed on the gasket and the mounting plate; The spray holes are evenly distributed at the bottom of the spray cover, and the spray cover is located under the inlet cone and fixed on the lower surface of the mounting plate. The invention can fully mix the gas and liquid, the spraying area is large, the liquid phase deviation can be effectively avoided, the initial distribution of oil and gas entering the reactor can be greatly improved, the reaction operation condition can be improved, and the product quality can be improved.

The invention discloses a flotation machine that can automatically adjust the liquid level. The outer box of the flotation machine is composed of a rear cover, a front cover and two side covers, including a guide mechanism, a telescopic shaft and an inner box of the flotation machine; The inner box of the flotation machine is installed inside the outer box of the flotation machine, the guide mechanisms are respectively installed at the outer top of the outer box of the flotation machine, and the telescopic shaft is installed in the middle of the inner box of the flotation machine through the stirring mechanism. The bottom of the inner box is installed on the bottom of the outer box of the flotation machine through a plurality of telescopic springs, and a flotation mechanism is installed above the outer box of the flotation machine; the invention makes the During operation, the flotation machine can automatically adjust the distance between the liquid level and the flotation claw rake according to the weight of the pulp content in the box, so that the foam can be completely beaten out, the ore raw materials can be used to the maximum extent, and the labor intensity of manpower can be reduced at the same time. , improve production efficiency.

The invention discloses a wall building formwork applicable to intelligent construction of a vertical shaft. The outer surface of the formwork is coated with a Teflon coating; a main body comprises a core frame cylinder, curve sliding rails and segmental sliding forms, and formwork supporting and releasing actions of the segmental sliding forms are realized by the aid of radial contraction indirectly produced by vertical traveling of the segmental sliding forms in the longitudinal direction through the curve sliding rails. Leveling and centering of the formwork are subjected to servo adjustment by corresponding hydraulic oil cylinders after pose determination by sensors, and circularity regulation is not needed. The formwork has basic function of a concrete pouring envelop structure as well as capacity of monitoring and evaluating the quality and an evolution process of cast-in-place concrete by means of setting of pressure, temperature, moisture and ultrasonic measurement points on the outer surface of the formwork. The formwork has the characteristics of being reasonable in structure, reliable in work, quick in action and capable of performing automatic centering and leveling and evaluating the pouring quality of the concrete in real time, and realizes intelligence of the construction process of the vertical shaft.
