The invention provides a color wheel comprising a motor, a carrier, a color wheel piece and an ultraviolet optical filter, wherein the motor is provided with a rotor, the carrier is fixed on the rotor, the color wheel piece is connected with the carrier by solidification glue, and the ultraviolet optical filter is positioned on one side of the solidification glue opposite to the motor. The shape of the ultraviolet optical filter is matched with that of the color wheel piece. The ultraviolet optical filter can effectively obstruct ultraviolet light rays from entering the color wheel piece to refract or obstruct ultraviolet light refracting for plural times in the color wheel piece from irradiating on the solidification glue, and can prevent the connected quality of the solidification glue from deteriorating. In addition, the invention also provides a digital optical processing projector provided with the color wheel.

The invention relates to a combined ecological floating bed for water planting plants and flowers, which is characterized by comprising one or more ecological floating bed units which are combined, interconnected and fixed to form the combined ecological floating bed for the water planting plants and flowers with various patterns; the ecological floating bed unit comprises a planting basket, a floating bed framework and a foam piece, wherein the planting basket is placed in a planting basket placing port of the floating bed framework; the foam piece is sleeved in a cavity of the floating bed framework; and a plurality of ecological floating bed units are connected to form a large-area water planing plant-flower garden or a fixed green ecological floating island. The ecological floating bed has the advantages of unique structure, convenient manufacture and low cost, can effectively reduce the content of phosphorus and nitrogen-like eutrophic salts polluting the water and COD and BOD, promote the water quality from VI class to III class and beautify the environment, and can be widely applied to the water surfaces of extensive polluted rivers and lakes.

The invention provides a flexible liquid crystal display. The flexible liquid crystal display comprises a first substrate, a second substrate and a liquid crystal layer, the first substrate comprisesa first flexible substrate, a second flexible substrate, a reflecting layer and an active element layer. The second flexible substrate is arranged on the first flexible substrate. The reflecting layeris arranged between the first flexible substrate and the second flexible substrate. The active element layer is disposed on the second flexible substrate. The second substrate is arranged on the first substrate. The liquid crystal layer is arranged between the first substrate and the second substrate. The substrate of the flexible liquid crystal display has good strength and can prevent laser from irradiating to the active element layer, so that an active element or a circuit of the active element layer is prevented from being damaged.

The invention relates to a conical hood mechanism of a titanium slag furnace, which at least comprises a main beam, wherein the main beam is formed by an outer conical circle and an inner conical circle. The conical hood mechanism is characterized in that the inner conical circle is positioned above the outer conical circle, and the diameter of the inner conical circle is less than that of the outer conical circle; the outer conical circle and the inner conical circle are fixedly connected through a plurality of secondary beams; cover plates are arranged in void positions formed between the main beam and the secondary beams; and the outer side of the outer conical circle is connected with a dust box. According to the conical hood mechanism disclosed by the invention, ascending fume in the furnace is spirally moved to form spout fume cloud, the fume in the furnace is circularly moved in a hood faster and faster, so that the self forming force of the fume is increased, the fume is moved in an organized way, and the possibility of discharge and diffusion in an unorganized way cannot occur; additionally, a molten pool in the furnace can be effectively prevented from irradiating a body of the hood is effectively prevented from being irradiated by the high temperature due to high temperature and heat radiation in a molten pool by the thick spout fume cloud, so that the heat absorption capacity of high molecular jointing materials is reduced, and the high molecular jointing materials are prevented from cracking caused by large change of temperature difference and shedding caused by cripling; and the circulating water temperature of the cover plates of the hood is effectively reduced.

The invention relates to β-carotene microcapsules rich in sardine oil, a preparation method and application thereof. In the present invention, denatured starch, chitosan, trehalose, sucrose, and monoglyceride succinate are sequentially added to water, stirred while adding, mixed evenly, and the solution is kept at a certain temperature to obtain the water phase, β-carotene crystals, Add lipophilic emulsifier Tween and sardine oil into the oil phase kettle, stir and dissolve to obtain the oil phase, slowly add the oil phase into the water phase, and make a microemulsion by shearing, and the microemulsion is prepared by concentrating, freeze-drying, grinding, etc. Microencapsulated beta-carotene enriched with sardine oil. Compared with the prior art, the obtained β-carotene microcapsules of the present invention not only improve the stability of β-carotene to factors such as light, heat and humidity, but also are rich in sardine oil in the microcapsules, which can combine with β-carotene Play a synergistic effect and improve the health care performance of microcapsules.
