The utility model provides an object surface impurity removing device, relates to the technical field of cleaning equipment, and solves the technical problems of low efficiency and time and labor waste when the surface of a product is cleaned manually. The object surface impurity removing device comprises a rack; the conveying assembly is mounted on the rack and used for conveying the to-be-treated products; the dust removal assembly is installed on the rack, located above the conveying assembly and used for removing impurities on the surfaces of the passing products to be treated; the protective cover assembly is installed on the machine frame, and at least part of the dust removal assembly and at least part of the conveying assembly are covered with the protective cover assembly. The cleaning device can be installed at the rear section and the front section of a production assembly equipment line body and used for cleaning the surfaces of objects before packaging, and cleaning is simpler and more thorough through the design of polygon and automatic blowing; and for some dust conditions, manual work can be replaced, so that occupational diseases are prevented.

The application provides a kind of biobased degradable industrial degreasing cleaning agent and its preparation method, it is related to the field of industrial degreasing cleaning agent, it includes biobased wetting penetration component, biological emulsification curling core component, natural plant solubilization component, non-phosphorus biological chelation component, natural corrosion inhibition dispersion buffer component, environmental protection bacteriostatic low-foam auxiliary agent, deionized water carrier, core function raw material is taken from plant fermentation, natural oil, microbial fermentation product, abandon petroleum-based non-degradable auxiliary agent, realize the biodegradation of all components, build wetting+permeation+solubilization+emulsification+curling+dispersion six-element synergistic degreasing system, overcome the industry pain point that traditional water-based cleaning agent is difficult to clean thick lithium / calcium / urea-based grease, heavy oil stain 10s rapid stripping effect.

The utility model provides a tungsten-molybdenum metal smelting device which comprises a smelting furnace, a smelting cover is installed at the top of the smelting furnace, an exhaust port is formed in the top of the smelting cover, an anti-blocking exhaust mechanism is arranged at the top of the smelting furnace and comprises an assembly frame, a two-way screw is installed between the two ends in a cavity of the assembly frame, and the two-way screw is connected with the two-way screw. The two ends of the outer side of the two-way screw rod are both sleeved with displacement sliding blocks, connecting rods are installed on one sides of the two displacement sliding blocks, mounting rods are installed on the tops of the two displacement sliding blocks, and the exhaust mechanism can prevent the situation that an exhaust pipe of the device is blocked in long-time use, so that follow-up cigarette ash of the device cannot be discharged in time; the cigarette ash is accumulated in the device, the failure rate of the device is increased, the maintenance cost is increased, meanwhile, potential safety hazards possibly caused by cigarette ash accumulation are avoided, an exhaust pipe of the exhaust mechanism is formed in an assembled mode, and a user can conveniently clean the cigarette ash on the inner wall.

The invention discloses an oral cavity diagnosis and treatment auxiliary method and system based on augmented reality, and the method comprises the steps: obtaining oral cavity diagnosis and treatment operation plan auxiliary information, making a patient oral cavity AR display model through employing the obtained CT image data, and turning on an oral cavity endoscope cold light source and a high-definition camera before operation diagnosis and treatment, the position of the high-definition camera is adjusted in real time to complete collection of an operation high-definition image, the operation high-definition image is transmitted to the AR server, the AR server stores data of the whole operation process, the operation high-definition image and a patient oral cavity AR display model are fused, and the operation high-definition image is obtained. According to the AR glasses, receiving and displaying the generated operation and oral cavity AR real-time fusion image and the extracted key auxiliary information, performing further operation treatment work; the invention has the effects of improving oral disease treatment efficiency, reducing oral treatment cost and guaranteeing physical health of oral doctors.

The application discloses a cable trench cover plate intelligent hydraulic lifting system and a running method thereof, and belongs to the field of cable trench cover plate lifting equipment. The system is an independent mobile external device, is not integrated in the cover plate body, and comprises a walking and supporting chassis, a four-column synchronous lifting system, a self-adaptive grabbing hook system, an environment sensing module and a control system cluster. The system realizes millimeter-level centering through two-stage positioning, realizes cover plate horizontal lifting by relying on master-slave displacement following load distribution dynamic compensation algorithm, and realizes non-destructive locking of the cover plate without a preset lifting hole through the self-adaptive grabbing hook. The three safety interlocking mechanisms form a software and hardware double insurance. The application realizes single-person operation of the cover plate opening and closing, solves the problems of low efficiency and high risk of manual carrying, and solves the problems of general equipment adaptation to narrow space and cover plate without lifting points, improves operation safety and operation and maintenance efficiency, and can realize equipment health assessment and remote monitoring, and adapts to high-frequency operation and maintenance requirements of the power and municipal industries.
