The present application relates to a kind of grinding rotor, including top wall, and with top wall connection side wall, grinding rotor inside is opened with grinding inner cavity, the outer periphery of side wall is provided with multiple grinding bars, the cross-sectional area of grinding bar is along the decreasing trend of grinding rotor radial direction from inside to outside, at least part grinding bar is provided with first inclined plane in the face side along the direction of rotation of grinding rotor, first inclined plane is arranged with horizontal plane angle;Side wall is provided with several heterodirectional variable-diameter channels, each heterodirectional variable-diameter channel is gradually tapered from inside to outside, each heterodirectional variable-diameter channel includes top surface, first side, bottom surface and second side connected in sequence, top surface and bottom surface are arranged with angle between them. Through the design of grinding bar and heterodirectional variable-diameter channel and cooperate with separating wheel assembly, avoid forming grinding dead zone in grinding cavity, and effectively improve the grinding efficiency and grinding uniformity.The present application also relates to vertical nanometer sand mill with the grinding rotor.

The application relates to the technical field of catalyst materials, in particular to a preparation method and application of a catalyst for synthesizing dimethyl carbonate from carbon dioxide and methanol; the method comprises the following steps: A, poloxamer is configured into a solution, HAc, NaClO4 and 1,3,5-trimethylbenzene are added into the solution and uniformly mixed to obtain a mixture; B, (NH4)2Ce(NO3)6 and H2BDC are added into the mixed solution in step A, the obtained solid after reaction is centrifugally separated, washed, soaked and dried to obtain a primary product, and finally the catalyst is obtained through calcination; in the application, HF-UiO-66 is synthesized by taking F127 as a template agent and taking 1,3,5-trimethylbenzene (TMB) as an expanding agent; the derivative HF-CeO2 catalyst with different TMB adding amounts is prepared through calcination; the adding of the expanding agent greatly increases the specific surface area of the catalyst, the CeO2 crystal grains generated through calcination are small, the number of acid-base sites is greatly increased, and therefore the catalyst has the largest catalytic activity, and the DMC yield reaches 12.02 mmol DMC / g cat .

This utility model discloses an MVR evaporator crystallizer, including a support, a filtration mechanism, and a preheating mechanism. The support has the evaporator crystallization mechanism at its front end and a centrifugal pump at its lower end. The filtration mechanism includes a filter box, a spiral blade shaft, a filter cylinder, and a collection box. The filter box is located at the rear of the lower end of the support, and the collection box is located at the right end of the filter box. An inclined filter cylinder is fixedly connected to the upper left side wall of the filter box. The right end of the filter cylinder is open and connected to the collection box. A connection port is located at the upper left end of the filter cylinder. A spiral blade shaft is rotatably connected inside the filter cylinder, and the bolts on the spiral blade shaft contact the inner wall of the filter cylinder. The inlet of the centrifugal pump is connected to the lower end of the filter box via a connecting pipe. This MVR evaporator crystallizer reduces maintenance frequency through pretreatment filtration and reduces steam consumption through preheating.

This application provides an in-vehicle sensing device, a control method, a control device, and a terminal device. The in-vehicle sensing device includes a sunshade and a light sensor. The opening of the sunshade faces the vehicle's glass, and the light sensor is mounted on the sunshade. Light is transmitted to the light sensor through the vehicle's glass and the opening of the sunshade, forming a sensing space between the light sensor and the vehicle's glass. A dehumidifying element is installed on the sunshade to remove moisture from the sensing space. This in-vehicle sensing device integrates a dehumidifying element, which dehumidifies the sensing space between the light sensor and the vehicle's glass, reducing the probability of frost or fogging on the vehicle's glass caused by temperature differences between the vehicle's interior and exterior. This helps improve the in-vehicle sensing device's perception of the external environment, thereby ensuring the normal operation of the vehicle's intelligent driving system.
