The invention discloses a fireproof moisture-proof easily-laid environmentally-friendly ceramic tile with locking buckles and a production method. According to the production method of the environmentally-friendly ceramic tile, a waterproof substrate layer is composited on the back surface of a ceramic tile body layer by a pressing overlaying process or an in-mold forming process. The environmentally-friendly ceramic tile comprises the ceramic tile body layer located on the upper layer, the waterproof substrate layer is composited on the bottom surface of the ceramic tile body layer, a clamping slot or a clamping tenon is formed in the side surface of the waterproof substrate layer, and the clamping slot and the clamping tenon are connected with each other in a clamped and matched mode, sothat every two environmentally-friendly ceramic tiles can be assembled and connected together. The fireproof moisture-proof easily-laid environmentally-friendly ceramic tile has simple structure, thewaterproof substrate layer enables the environmentally-friendly ceramic tile to have high temperature resistance, fireproof, moisture proof and waterproof functions, and the environmentally-friendlyceramic tile is directly laid on the ground during laying; during the laying process, the clamped connection is directly achieved by the clamping slot or the clamping tenon, and the clamped connectionis simple and convenient; the environmentally-friendly ceramic tile is automatically leveled by the waterproof substrate layer, and no hollowing phenomenon exists; and after the laying, the laid environmentally-friendly ceramic tile can be used without brushing the ground or pre-filling or flattening cement sand, and the ceramic tile laying is simpler, faster and more convenient.

Complete production device of energy-saving high-efficiency biomass fuel particles

InactiveCN102732352AEasy to maintain and replace templatesReduce electricity dependenceBiofuelsDrying gas arrangementsPulverizerRenewable energy
The invention provides a complete production device of energy-saving high-efficiency biomass fuel particles. The device comprises a pulverizer, a dryer, a granulator and a packager. The complete production device of the energy-saving high-efficiency biomass fuel particles of the invention adopts a fast assembling structure of a large-modulus trapezoid screw thread to make template maintenance and replacement be convenient and simple. Renewable energy utilization and energy utilization efficiency improvement concepts are protruded, so heat generated in the product compression procedure in the production process is recovered, and is used for drying raw materials; and the dependence on electric energy is reduced, and energy saving and emission reduction control in the production process is reached. The single press roller structure of the plate type press roller sets of the invention is different from the single press roller structures of common granulating devices, so the static friction resistances of the press rollers, generated because of a linear velocity difference in a working state, are reduced, thereby the power consumption of the device is reduced, and energy is saved. Compared with foreign like products, the biomass fuel particles produced in the invention have the advantages of energy saving, uniform density, high energy utilization rate, and convenient maintenance.

Ionic membrane reinforced electric-oxidation repair method of organic polluted soil

The invention discloses an ionic membrane reinforced electric-oxidation repair method of organic polluted soil, relates to a reinforced electric-oxidation repair method for removing organic pollutants in soil, and solves the problems of easy generation of a reduction reaction near a cathode by an oxidizing agent, low utilization rate of the oxidizing agent and easy change of basic properties of the soil in a traditional electric-oxidation repair technology. The method comprises the following steps: a cation exchange membrane or an anion exchange membrane is mounted between an electrode and target soil; then, oxidizing agent solution is injected in one side, near the soil, of the ion exchange membrane; and direct-current voltage is applied for treatment by a certain time to finish repair of organic pollution. The method has the following advantages: (1) the loss of the oxidizing agent can be prominently reduced; and additional other chemical reagents are not needed for reinforced repair; (2) the removing efficiency of organic pollutants can be greatly improved; and meanwhile, the energy consumption is reduced; (3) the influence on the soil properties can be reduced; and (4) installation, use and replacement of the ion exchange membrane are simple and convenient.

Method for replacing character by input method and client

The invention provides a method for replacing a character by an input method and a client and belongs to the technical field of communication. The method comprises the following steps: acquiring a character to be replaced and acquiring an attribute of the character; judging whether an attribute of a current character string input by an input method tool is consistent with the attribute of the character to be replaced or not; and if no, after regulating the character string input by the input method tool to ensure the character string to have the same attribute with the character to be replaced, loading the character string into the position of the character to be replaced to carry out replacement operation or outputting the regulated character string serving as a candidate item by a candidate item list. Due to the utilization of the method, when character contents are replaced, the attribute of the character string input by the input method tool is converted into an attribute which is the same with that of the character to be replaced and then the converted attributed is output; the defect that in an existing input method tool, character input states need to be repeatedly and manually switched is overcome; the character replacement efficiency is improved; and the user experience of a user is more excellent.

Intensive multifunctional continuously-variable valve driving system for four-cylinder internal combustion engine

The invention discloses an intensive multifunctional continuously-variable valve driving system for a four-cylinder internal combustion engine, and belongs to the field of internal combustion engine variable valve driving systems. The intensive multifunctional continuously-variable valve driving system mainly comprises oil feeders, a cycle selector, a mode converter, two-position two-way valves, an air valve driver and the like. According to the designed cycle selector, a variable valve event required by the driving mode and the braking mode of the internal combustion engine can be achieved simply through the two oil feeders and the two two-position two-way valves, and a strong function is achieved with extremely low cost. The air valve closing process is not limited by the operating stages of the oil feeders, an air valve early closing event required by the idling and medium-low load of the internal combustion engine is met, and the oil consumption and emissions of the internal combustion engine in actual application are fully reduced. The intensive multifunctional continuously-variable valve driving system can be applied to a naturally suction type internal combustion engine and a turbocharging type internal combustion engine only by exchanging the communicated objects of two oil ports in the mode converter, and is good in type adaptability and wide in application range. All the components of the system are connected through oil pipes, and the system can be arranged on an actual machine type conveniently.
