4results about How to "Exemption from cleaning" patented technology

The present invention relates to the technical field of heat exchangers, and in particular to a fully intelligent, cleaning-free, non-laminar heat exchanger, comprising a heat exchanger and a cooling pipe arranged on the inner side of the heat exchanger, wherein the top and bottom ends of the cooling pipe are fixedly connected with water pipes that penetrate the cooling pipe. In the present invention, an ultrasonic component, an ultrasonic transducer, a high-frequency cable, a main unit, a power cord and a connecting pipe are arranged, and the main unit is started when the device is used. At this time, the ultrasonic transducer at the bottom end of the high-frequency cable begins to emit ultrasonic shock waves, which propagate inside the cooling pipe, and simultaneously generate high-speed micro-impacts on the inner and outer sides thereof. The micro-impacts on the inner side destroy the laminar layer in the cooling pipe, and convert heat conduction into convection heat exchange. The arrangement of the ultrasonic component improves the heat exchange efficiency. At the same time, the micro-impacts on both sides of the cooling pipe prevent scale from approaching and adhering to the inner wall of the cooling pipe, thereby eliminating scaling and eliminating the need for cleaning of the cooling pipe.

The application discloses a polishing-etching integrated processing technology for high-finish jade crystal stone material, and the technology comprises the following steps: providing an integrated processing device integrating chemical mechanical polishing and chemical etching functions, and deploying a multi-source sensor online monitoring system; synchronously collecting multi-dimensional parameters such as polishing pressure, torque, temperature, pH value, fluoride ion concentration, acoustic emission signal and online roughness; adopting a random forest algorithm to screen key features, and establishing a surface roughness real-time prediction model based on support vector regression or artificial neural network; the application realizes real-time sensing, accurate prediction and self-adaptive regulation of jade crystal stone polishing-etching integrated processing, the processing efficiency is improved by more than 50%, the surface roughness is less than or equal to 0.01 mu m, the good product rate is greater than or equal to 94%, and the application is suitable for high-finish jade crystal stone material processing in the fields of high-end building decoration, electronic cover plate and precise optical device.

The utility model discloses a kind of heating dining table with intelligent constant-temperature warehouse, including the dining table base of lower end, the heating component of middle end, the tabletop of upper end, be provided with constant-temperature warehouse for warming dishes and other heatable food between the tabletop and heating component.The utility model is provided with constant-temperature warehouse for dishes heat preservation and heatable food under existing dining table, whereby dishes and heatable food can be placed in the cavity inside it in cold weather, heat air inside reaches the condition of dishes heat preservation and heatable food, when internal air is not very high (control between 30 ℃~80 ℃, can be adjusted appropriately according to air temperature and required temperature), it will not have greater influence on the taste of fried dishes and heatable food, while non-steam heat preservation mode, to a great extent, the original juice of dishes is kept, constant-temperature warehouse is directly arranged under dining table, increase the functionality and practicality of dining table.

This utility model relates to the field of machining center technology, and in particular to a protective structure for machining centers. This protective structure includes a protective body with a sliding door; a window on the sliding door; a first guide rail at the top of the sliding door; a pulley at the bottom of the sliding door; a first slider at the top of the protective body; a second guide rail suspended inside the protective body, with a pedal below the second guide rail; a clearance groove at the bottom of the protective body; the end of the second guide rail extending into the clearance groove; the first guide rail sliding along the first slider; the pulley moving along the second guide rail; a housing located at the first edge of the protective body, with an air conditioner mounted on the door panel of the housing. The cutting debris falls from top to bottom, preventing it from landing on the first guide rail or the first slider. Simultaneously, because the second guide rail is suspended, debris falls directly from the side of the second guide rail into the pedal, thus ensuring smooth operation of the sliding door.
