The application relates to the technical field of solid-liquid reaction equipment, in particular to a device for solid-liquid reaction. The device is characterized in that a liquid inlet is arranged on the side wall of a reaction body near the top end, so that liquid-phase materials can be fed from the top of the reactor; the disturbance suspension disc is combined with the hollow shaft to make up-and-down reciprocating motion, so that high-concentration liquid-phase materials gradually flow to the bottom of the reaction body; the solid-phase materials are gradually fed into the feeding pipe through the spiral conveying mechanism, and then enter the bottom of the reaction body through the feeding pipe to contact and react with the low-concentration liquid-phase materials formed by reaction; when the disturbance suspension disc makes up-and-down reciprocating motion with the hollow shaft, the solid-phase particles are disturbed to suspend upward, and then contact and react with the liquid-phase materials with higher concentration, so that the relative amount or relative concentration of the solid-phase materials and the liquid-phase materials when they contact is weakened, the intensity of the reaction is weakened, the safety is improved, the small solid-phase materials can be prevented from being wrapped in the product, and the thoroughness of the reaction is improved.

The utility model relates to rail clamp technology field discloses a rail clamp for elevator installation, including fixed base, the fixed base outer wall one side is provided with clamping mechanism, the fixed base upper end is provided with adjusting mechanism, the clamping mechanism includes first fixed block, first fixed block outer wall one side is connected with the inclined fixed block, first fixed block and inclined fixed block outer wall one side are connected with fixed plate, the fixed base inside is provided with hydraulic pressure rod, the hydraulic pressure rod upper end is connected in fixed plate bottom end face one side. In the utility model, through the mutual cooperation between the hydraulic pressure rod, fixed plate, fixed block, clamp block that set up, can clamp the elevator slide rail, avoided because long -time use bolt, make bolt damage the security hidden danger that produces, through the mutual cooperation between the pull rod, spring, pulley, can be convenient for with device moves to the appropriate position and fixes, avoided frequently disassembles bolt, again with device removes to the appropriate position, convenient operation.

The utility model discloses a bolt looseness detection device which comprises an equipment shell, a circumferential driving mechanism, a torque transmission mechanism and an execution mechanism, the equipment shell is composed of an upper shell body and a cover plate which are fixedly connected through a bolt, and the cover plate is located on the lower surface of the upper shell body. The circumferential driving mechanism comprises a driving straight gear installed in the center of the interior of the upper shell and five driven straight gears arranged around the driving straight gear. Compared with the prior art, the utility model has the beneficial effects that a meshing structure of the central driving straight gear and the five groups of driven gears is adopted to realize that a single pneumatic motor drives multi-station synchronous operation, and when the torque is greater than the design value of the magnetic coupling, the magnetic coupling does not transmit power, so that the bolt can be prevented from being excessively tightened; and compared with the traditional single-time one-by-one detection, the automobile hub bolt detection efficiency is greatly improved by using five-station parallel detection.

The utility model discloses a kind of self-cleaning type scrapers for dry coal slime, belong to material conveying equipment technical field, including scraper body and self-cleaning unit, scraper body has groove and groove in-circulation chain plate assembly, chain plate assembly includes chain and the scraper plate of interval arrangement.Self-cleaning unit is rigid metal scraper, is arranged in pairs in the front of scraper running direction two sides, and is arranged obliquely to corresponding side groove side wall, scraper and chain running direction present 40 ° to 50 ° acute angle, welding or through fixed support rod and locking bolt is detachably fixed on chain adjacent chain ring connection place.The utility model utilizes rigid scraper in operation to force to scrape dry coal slime in the jointing of groove side wall and chain plate assembly gap inner plate, effectively prevent chain overload, tensioning and chain breakage accident caused by material accumulation, with the advantages of good cleaning effect, reliable operation, convenient maintenance.

The utility model discloses a kind of hemostasis bandaging equipment, it is related to medical equipment technical field, including hemostasis fixed sheet, when using, hemostasis fixed sheet is placed in the bottom of affected limb, two ends of wide cloth strip are respectively threaded from two big fixed slots, two ends of wide cloth strip are mutually close and then reverse movement is pulled tight and knotted, so that wide cloth strip is carried out bandaging to affected limb, when pulling wide cloth strip, hemostasis fixed sheet is stressed to bend, and affected limb is adhered, when knotting wide cloth strip, under the action of hemostasis fixed sheet, the bottom of patient's limbs is stressed evenly, avoid excessive extrusion limbs.Postoperative needs to carry out suspension to limbs, two narrow cloth strips are respectively threaded from small fixed slot, and after being wound knot head with the outer surface of hemostasis fixed sheet, narrow cloth strip is hung in the position required, and limbs are suspended, the force of limbs is on hemostasis fixed sheet, narrow cloth strip and knot head at this time, avoid to tighten wound, avoid blood circulation is hindered.
