The invention discloses a biomass direct combustion furnace, which comprises a furnace furnace, a furnace head, a furnace frame, a feeding device, and an air supply mechanism. In the upper air hole, a charging device is fixedly installed under the furnace, and the charging device is fixedly connected to the furnace frame. The charging device includes a feeding cylinder and a lifting mechanism. A fire grate is arranged on the upper part of the cylinder, and the fire grate is hinged with the feeding cylinder, and a ventilation hole is arranged on the fire grate; the biomass fuel is directly burned through the biomass direct combustion furnace provided by the present invention, and after being ignited from above, start Combustion is carried out from top to bottom. When the fuel in the combustion chamber formed by the furnace and the grate is burned out, secondary feeding can be carried out from the lower part of the furnace through the charging device.

The invention belongs to the technical field of lithium ion batteries and especially relates to a preparation apparatus for lithium ion battery slurry. The apparatus comprises a solvent loading tank and a slurry agitator tank, wherein the slurry agitator tank is connected with a first vacuum pump; the apparatus further comprises a binder premixing tank, wherein the binder premixing tank is connected with a second vacuum pump; a discharge outlet of the solvent loading tank is connected with a feed inlet of the binder premixing tank through a first pipeline, and a discharge outlet of the binder premixing tank is connected with a feed inlet of the slurry agitator tank through a second pipeline. Compared with the prior art, the preparation apparatus provided by the invention has the following advantages: fluids like a solvent and a binder premixed liquid are added from the bottom of a tank to the top of the tank by using vacuum negative pressure, so it is guaranteed that there is only a two-phase interface of a liquid phase and a solid phase, maximum-efficiency mutual infiltration is realized, generation of bubbles in the slurry is reduced, dispersion is promoted, stirring time is shortened and operation is simple, which enables stirring time to be reduced and production efficiency to be improved. Furthermore, the invention also discloses a method of utilizing the apparatus for preparation lithium ion battery slurry.

The invention discloses a method for automatically extracting theanine from tea. A fermenting rack body is included. A fermentation chamber is arranged inside the internal wall of the fermenting rackbody. A transmission chamber extends to left and right sides at the top of the fermentation chamber inside the fermenting rack body. A sliding seat is in sliding fit inside the transmission chamber. Afirst motor is fixedly arranged in the left cross section of the sliding seat. The left end of the first motor is in power fit with a first bevel gear. The left end of the first bevel gear is in running fit with a connecting rod which extends towards left and right sides. The bottom of the first bevel gear is engaged with a second bevel gear, the bottom of which is fixedly provided with a main rotating shaft. The main rotating shaft extends downwards into the fermentation chamber to be in running fit with upper and lower walls of the fermentation chamber. Agitator arms are circumferentially and fixedly arranged on the external surface of the main rotating shaft. Agitating valves are symmetrically and fixedly arranged at upper and lower end faces of the agitator arms, far from one side ofthe main rotating shaft.

The invention discloses a method for preparing polyacrylate by single electron transfer-living radical polymerization. The method comprises the following steps of adding a dispersant aqueous solution into deionized water, adding a pH conditioning agent, a catalyst, a monomer and an initiator into the dispersant aqueous solution at a temperature of 10 to 60 DEG C for a reaction lasting for 10min-10h, stopping stirring, removing water in the reaction system, putting the product into a vacuum drying oven, and carrying out drying at a temperature of 20 to 60 DEG C to constant weight so that the active polyacrylate product is obtained, wherein a mole ratio of the monomer, the initiator, the pH conditioning agent to the catalyst is (10-4000): 1: (1-40): (1-30); a mass ratio of the dispersant to the monomer is (700-50000ppm): 1; and a volume ratio of the monomer to water is 1: (1-20). The method can realize synthesis of the molecular weight-controllable active polyacrylate at a room temperature or a lower temperature. The polyacrylate product can be used as a macro-molecule initiator, and sequentially initiates polymerization of other monomers so that an ABA segmented copolymer is produced. The method has the advantages of fast polymerization rate, high monomer conversion rate, strong controllability and environmental friendliness.
