The present invention is a concrete vibrating device for municipal engineering construction. A conical hole penetrating up and down is arranged on the vehicle floor. The upper end opening of the shaped hole is attached to the outer wall of the vibrating rod. The angle at which the vibrating rod is inserted into the concrete of the present invention, and the inclination angle of the vibrating rod are mainly adjusted manually before construction; after the insertion depth and inclination angle of the vibrating rod are adjusted in place, the front and rear positions of the first block and the second block are adjusted, and The vibrating rod is positioned by the first block and the second block. The vibrating rod can be easily moved by operating the guide car, and the bottom plate of the car can also level and suppress the concrete surface by itself. It is not only effective in use, but also simple and convenient to operate. Even if different construction personnel, the vibrating effect on concrete after operation is basically the same, and the industrialization is strong.

The invention relates to a guacetisal dry suspension, the formula of which for preparing 1,000 bags comprises the following raw materials (by weight parts) guacetisal 160-170, hydroxypropyl methyl cellulose 5-10, sodium lauryl sulfate 5-10, sucrose 815-820, and a proper amount of fresh milk essence, wherein the sodium lauryl sulfate is used as a wetting agent for facilitating suspension. The guacetisal dry suspension has the advantages of good settling volume ratio, long suspension state keeping time, good stability, and good mouthfeel; and is more suitable for administration by children and patients suffering from dysphagia.

The invention belongs to the technical field of biomass catalysis, and specifically relates to a preparation method and application of a carbon-based solid acid. The invention uses one or more of glucose, fructose, starch, and sucrose as a carbon source, and adds an appropriate amount of liquid acid to the catalyst Carry out modification to prepare carbon-based solid acid; use the prepared carbon-based solid acid to catalyze the reaction of carbohydrates to prepare 5-hydroxymethylfurfural, which has a mild reaction process, the catalyst used is environmentally friendly, and the process is simple and economical. The industrialized preparation of the platform compound 5-hydroxymethylfurfural provides a new way to promote the preparation of petroleum-based chemicals and alternative fuels from biomass, which has strong industrial significance.

A dry suspension of methocarbamol contains methocarbamol and the pharmacologically acceptable carrier including cellulose derivative chosen from hydroxypropyl methyl cellulose, and microcrystalline cellulose, flavouring (cane sugar), and adhesive (the mixture of alcohol and water).

The invention provides a method for preparing a hyperbranched polymer based on carbon nanotubes, comprising the following steps: step 1, taking hydroxylated carbon nanotubes, grafting a silane coupling agent on its surface, and the silane coupling agent contains terminal amino group; step 2, carry out at least one hybridization treatment to the product in step 1, and the hybridization treatment process is as follows: graft methyl acrylate and organic diamine on the product of step 1 in sequence; step 3, take step 2 The product in , is capped with maleic anhydride; step 4, take 0.1 parts by weight of the product in step 3, and carry out free radical copolymerization in water phase with 20-40 parts by weight of acrylamide. The hyperbranched polymer of the present invention, whose polymerization main body is one-dimensional carbon nanotubes, can pass through smaller-sized pore throats compared with traditional hyperbranched polymers; at the same time, the synthesis method of the present invention is simple, highly repeatable, and Energy saving and environmental protection, strong industrialization.

The invention relates to a gas guide type anaerobic reactor. The gas guide type anaerobic reactor comprises one or a plurality of anaerobic reaction tanks connected in series; a water inlet, a water outlet, an exhaust port and a slag outlet are formed in the outer part of each of the anaerobic reaction tanks; a feed plate, a guide plate and a sludge plate are arranged at the inner part of each of the anaerobic reaction tanks, wherein the feed plate is arranged at one side close to the water inlet; the sludge plate is arranged at one side close to the water outlet; the guide plate is arranged between the feed plate and the sludge plate; the guide plate and the sludge plate are movably connected to the inner part of each of the anaerobic reaction tanks; the feed plate and the guide plate define a sludge suspension area; the guide plate and the sludge plate define a precipitating area; a reaction area is formed in the bottom part of each of the reaction tanks. Compared with the prior art, the gas guide type anaerobic reactor has the advantages that the muddy water reaction time and the sludge precipitation time can be adjusted by controlling the volumes of the sludge suspension area and the sludge precipitating area; in addition, the gas guide type anaerobic reactor has good load to impact, and is high in fermenting efficiency, wide in applicable range, high in sludge utilization rate, low in energy consumption, simple in design, and convenient in equalization.
