The invention relates to a sludge concentration tank, a sludge concentration system and an application method.The sludge concentration tank comprises a tank body (1), the interior of the tank body is composed of a gas collecting area (4), a settling area (5) and a sludge storage area (6) from top to bottom, the gas collecting area is provided with a gas outlet (7), the side wall of the settling area is provided with a sludge feeding pipe (8), and the upper portion of the settling area is provided with a liquid discharging pipe (12); a sludge discharge pipe (9) is arranged at the bottom of the sludge storage area; the rotational flow inner part (2) is arranged in the settling area, the rotational flow inner part is a cylinder with the pipe diameter reduced from top to bottom, an opening in the bottom of the rotational flow inner part is a mud outlet, the top of the rotational flow inner part is closed, a clear liquid outlet (16) is formed in the rotational flow inner part, and a feeding opening is formed in the side wall of the rotational flow inner part and communicated with the sludge feeding pipe. The sludge concentration tank and the sludge concentration system can realize efficient separation of sludge and water, and the subsequent sludge treatment energy consumption is reduced; meanwhile, gas is collected, and the deodorization effect is achieved. The working efficiency and the separation efficiency are relatively high.

The application provides a spina date seed and poria cocos sleep-aiding composition, a preparation method and application thereof, and belongs to the technical field of functional food. The application uses poria cocos polysaccharide as an efficacy component and embedding carrier, and the efficacy is synergistic with spinozine and saponins in spina date seed to aid sleep, the structure is molecularly embedded spinozine and saponins in spina date seed through molecular level interaction, the bioavailability of effective components in spina date seed is significantly improved, and therefore, a better sleep-aiding effect is achieved.

This invention provides a tire with a tread pattern. Multiple longitudinal grooves in the tread pattern are spaced apart along the width of the tire, dividing the tread into two shoulder tread portions and a central tread portion between the two shoulder tread portions. Groove structures are provided on the central tread portion, each groove including a first recess and a first sipe that are interconnected. The end of the first recess away from the first sipe extends into a longitudinal groove on one side of the central tread portion, and the end of the first sipe away from the first recess extends into a longitudinal groove on the other side of the central tread portion. The extension direction of the first recess forms a first angle A1 with the first sipe. Multiple groove structures are spaced apart along the circumference of the tire, and the first recesses of adjacent groove structures are connected to different longitudinal grooves. This invention effectively solves the problem in the prior art where tires cannot simultaneously meet the requirements of handling and comfort.

This invention relates to the field of interlayer technology in laminated glass, and particularly to a binary composite plasticized gradient structure PVB interlayer, its preparation method, and laminated glass. The interlayer has a three-layer gradient structure, consisting of a first surface layer, a middle sound-insulating layer, and a second surface layer from the outside in. Both the first and second surface layers contain a first PVB resin and a first composite plasticizer, which includes diethylene glycol dibenzoate and 3GO. The middle sound-insulating layer contains a second PVB resin and a second composite plasticizer, which includes a mixture of diethylene glycol dibenzoate and 3GH. This invention, through innovative material formulation and structural design, provides a PVB interlayer solution that balances high weather resistance, excellent sound insulation, strong adhesion, low plasticizer migration tendency, and additional heat insulation functions. It also includes a stable and efficient preparation method, effectively overcoming the limitations of existing technologies where performance cannot be synergistically improved.
