  • Publication number: 20240286143
    Abstract: Solid-liquid separation equipment includes a pulverizing and drying device. The pulverizing and drying device includes a pulverizing device and a drying device connected with one another. The pulverizing device has a pulverizing shell, an inlet, a main shaft and impellers, and the main shaft and the impellers are arranged in the pulverizing shell. The impellers are configured to rotate around the main shaft. The inlet forms a sidewall of the pulverizing shell and is intersected with the main shaft or an extension line of the main shaft. A gap is defined between an outer peripheral end of the impeller and the wall of the pulverizing shell. The sludge is efficiently and deeply dried in a condition with no phase change. The sludge is graded, pulverized and dried. During the pulverizing and drying process, the water is liquefied and centrifugally separated, and the water is not completely phase-transformed and removed.

  • Publication number: 20240270781
    Abstract: Provided in the present disclosure is a preparation method of paeoniflorin-6?-O-benzene sulfonate. The method uses crude paeoniflorin instead of paeoniflorin as a raw material, which more complies with actual requirements of an industrial production process of paeoniflorin-6?-O-benzene sulfonate, and uses an organometallic catalyst, an acid-binding agent and chemically active benzenesulfonyl chloride to react with paeoniflorin. Compared with the prior art, the method significantly increases the yield of crude paeoniflorin-6?-O-benzene sulfonate which is separated and purified by means of column chromatography and then refined to obtain paeoniflorin-6?-O-benzenesulfonate with a content of at least 98%, thereby realizing industrial production of the paeoniflorin-6?-O-benzene sulfonate.

  • Publication number: 20130344382
    Abstract: The invention pertains to the technical field of a Li-ion battery, in particular to a Li-ion battery positive plate structure, comprising a current collector, a base diaphragm arranged on the surface of the current collector and a top diaphragm arranged on the surface of the base diaphragm; both the base diaphragm and the top diaphragm respectively comprise an active substance, an adhesive and a conductive additive, wherein, the active substance of the base diaphragm is graphite, while the active substance of the top diaphragm is at least one among silicon, silicon alloy and tin alloy. Compared with the prior art, the Li-ion battery positive plate structure of the invention successfully solves the problem of film removal of silicon anode and alloy anode due to swelling in the process of charging because a graphite anode base diaphragm with buffering function is installed between the top diaphragm with swelling trend.
