The utility model discloses a kitchen waste transferring and distributing mechanism which comprises a bottom plate, universal wheels with brakes are installed at the four corners of the bottom of the bottom plate, supports are welded to the four corners of the top of the bottom plate, a distributing box which is obliquely arranged upwards is fixed to the tops of the supports, and a feeding hopper is connected to the top of the lower side of the distributing box. The other end of the material distribution box is connected with a discharging pipe, and a vibration separation mechanism is installed in the material distribution box. According to the utility model, solid and liquid kitchen wastes fed by the feeding hopper can be subjected to solid-liquid separation under the action of gravity through the grid conveying belt, and the extension stopping strips protrude out of the grid conveying belt, so that the solid wastes can be prevented from sliding down from a high position; and the strip-shaped protrusions arranged on the driving roller and the driven roller can cause periodic vibration of the grid conveying belt, so that solid-liquid separation of the kitchen waste is accelerated, the inserting plate slidably inserted into the discharging pipe can stop discharging, and therefore the kitchen waste can be conveniently separated, collected, stored and transported.

The application discloses a solid-phase extraction instrument capable of collecting waste liquid, and belongs to the technical field of solid-phase extraction instruments.The solid-phase extraction instrument comprises a base and a support vertically fixed on the upper surface of the base, a plurality of extraction columns are installed on the support at equal intervals, a guide rail frame is fixedly installed on the support, a guide sliding groove is formed in the guide rail frame, a guide sliding block is slidably installed in the guide sliding groove, and a composite moving seat is installed on the guide sliding block; the composite moving seat comprises a bottom disc sliding along the direction of the guide rail frame, a rotating disc is rotatably installed above the bottom disc, a plurality of circular grooves are formed in the rotating disc at equal intervals along the axial direction, and a waste liquid tank is clamped and installed in the circular groove; a liquid discharge port is installed through the extraction column, an intelligent filtering mechanism for sensing and filtering the blockage in the liquid discharge port is arranged between the waste liquid tank and the extraction column, and the solid-phase extraction instrument can classify and collect waste liquid, can sense the blockage state of waste liquid discharge during the collection of waste liquid, can filter the slightly blocked filler particles, and can assist in the smooth collection of waste liquid.

The utility model relates to the technical field of coal ash processing, and one embodiment of the utility model provides a wastewater treatment system for coal ash separation, which comprises a treatment box, a feeding cover is arranged at the upper end of the treatment box, a feeding treatment assembly is arranged in the treatment box, and a filtering and cleaning assembly is arranged on the upper end surface of the treatment box; the feeding treatment assembly comprises a feeding port, an intercepting plate is arranged on the inner side wall of the treatment box, a receding groove is formed in the intercepting plate, a blocking plate is arranged on the lower end face of the inclined plate, a driving shaft is inserted into the blocking plate, a stirring piece is arranged on the driving shaft, and the stirring piece is located between the receding plate and the receding groove. According to the technical scheme, the technical problems that although some coal ash water treatment devices in the prior art have multiple functions of mixed reaction, precipitation, filtration and the like, the structural design is not reasonable enough, the treatment efficiency is not high, or automatic and efficient treatment cannot be well achieved when coal ash and waste water are separated are solved.

The utility model relates to the technical field of desilting of a water tank of an annular cooler, and solves the problem that the water tank of the annular cooler in the prior art is easily blocked by dust. The desilting device comprises a settling pond assembly which comprises at least three stages of settling ponds which are sequentially connected in series, and the heights of the settling ponds are sequentially decreased; one end of the drainage pipe is arranged in the upper water tank of the circular cooler, the other end of the drainage pipe is connected to the first sedimentation tank, and the drainage pipe is used for conveying the sludge-water mixture in the water tank into the sedimentation tank assembly; one end of the water feeding pipe is connected with the last-stage sedimentation tank, and the other end is arranged in the circular cooler water feeding tank; and a water pump is arranged on the water feeding pipe and is used for conveying the settled clear water back into the water tank. By adopting at least three stages of serially-connected sedimentation tanks with gradually-decreased heights, step-by-step sedimentation is realized by utilizing gravity self-flowing, the sludge separation efficiency is effectively improved, the content of suspended matters in clear water is reduced, the treated clear water is recycled, and the energy consumption is reduced.

The application provides a synchronous extraction method of soluble and insoluble dietary fibers, and belongs to the technical field of dietary fiber processing. The synchronous extraction method comprises the following steps: S1, taking pineapple pomace as raw material, diluting with water to obtain a sample liquid; S2, mixing the sample liquid, salt and an organic solvent, adding an acid-alkali reagent to adjust pH, obtaining a composite system, and placing the composite system in a multi-frequency ultrasonic field to perform separation and extraction, thereby obtaining a composite extraction system; S3, centrifuging the composite extraction system, removing the obtained upper liquid phase, and washing the middle layer solid phase to obtain pineapple insoluble dietary fiber; and performing dialysis desalting on the lower liquid phase to obtain pineapple soluble dietary fiber. The method has the advantages of simple process, short time consumption, high extraction rate and excellent product quality. In particular, the total extraction time is short, the extraction rates of soluble dietary fiber and insoluble dietary fiber are high, and the comprehensive utilization rate of pineapple processing by-products is greatly improved.
