The invention discloses a vertically-assembled balance arm mechanism and an adjustment method thereof. The vertically-assembled balance arm mechanism comprises a base and a guide rod column located on the base, wherein a sliding sleeve is installed in the middle of the guide rod column, the two ends of the sliding sleeve are respectively provided with a first linear bearing, a horizontal sliding plate which is perpendicular to the axial direction of the sliding sleeve is installed in the middle of the sliding sleeve, a suspender and a bearing are arranged at the top end of the guide rod column, one end of a balance crane is fixed on the suspender, and the other end of the balance crane is installed at one end of the sliding sleeve through a stud. The balance arm mechanism further comprises a linear bearing guide rod, wherein a horizontal sliding block where a second linear bearing is installed is arranged on the linear bearing guide rod in a sleeved mode, a front check block and a rear check block are installed at the two ends of the linear bearing guide rod respectively, a front clamping block and a rear clamping block are further arranged on the front check block, and a spanner is fixed on the front check block in a clamping mode through the front clamping block and the rear clamping block. According to the vertically-assembled balance arm mechanism and the adjustment method thereof, the electric or pneumatic spanner can stay at any position horizontally and vertically, and it is guaranteed that the spanner is located in the vertical direction all the time during movement and working.

The invention provides a seat armrest and an automobile seat. The seat armrest comprises an armrest framework, a rotation limiting mechanism and a return piece, wherein the armrest framework is rotationally connected with a seat backrest framework through a rotating piece; the rotation limiting mechanism can limit a rotation angle of the armrest framework; the rotation limiting mechanism comprises limiting teeth, which are arranged in a circumferential direction of the rotating piece, and a guide rod, which can rotate around the limiting teeth and is matched with a tooth groove of the limiting teeth; the return piece can drive the guide rod to be limited within the tooth groove when the armrest framework is rotated to a preset angle; and when the armrest framework is in rotating, the return piece can drive the guide rod to be separated from the tooth groove. According to the seat armrest, as the angle of the seat armrest is adjustable, the seat armrest can be adjusted to a comfortable angle according to a seat backrest at different angles and different use states of a passenger; therefore, the seat armrest can stay at an appropriate angle when the angle of the seat backrest is changed so as to ensure the taking comfort of the passenger.

The invention discloses a high-efficiency energy-saving hydrochloric acid pickling waste liquor triple-effect negative-pressure graphite evaporation crystallizer, belonging to the field of pickling waste liquoir treatment. The evaporation crystallizer disclosed by the invention comprises an evaporation concentration unit, a feed unit, a gas condensation unit, a cooling crystallization unit, a solid-liquid separation unit, a mother liquor circulating unit and a vacuum unit. The hydrochloric acid pickling waste liquor is heated in a vacuum state, so that volatile chlorine hydride and water in the solution are evaporated together, and are condensed through the gas condensation unit to form reusable clean hydrochloric acid; and the concentration of the nonvolatile metal salt in the solution is continuously increased to form a metal salt supersaturated solution, and the metal salt supersaturated solution is cooled by the cooling crystallization unit, so that part of metal salts are precipitated in the crystalline-state hydrous crystal, thereby achieving the goal of separating the solute and solvent in the solution. The invention mainly aims to provide a high-efficiency energy-saving hydrochloric acid pickling waste liquor triple-effect negative-pressure graphite evaporation crystallizer which has the advantages of favorable antiseptic property, high recovery ratio and low treatment cost.

The invention relates to an air outlet for a vehicle, comprising a housing with an air inlet opening and an air outlet opening, between which a flow connection is formed, further comprising a slat carrier, mounted movably in the housing, and a shut-off element which is movable between a closed position, in which it blocks the flow connection, and an open position, in which it frees the flow connection, the slat carrier being mounted movably in the housing, the slat carrier being coupled to the shut-off element such that, by actuation of the slat carrier, the shut-off element is adjustable between the closed position and the open position, the shut-off element being adjustable into intermediate positions between the closed position and the open position, starting from the closed position and / or starting from the open position, by actuation of the slat carrier, the shut-off element remaining in said intermediate positions until the slat carrier is actuated again.
