Clothes drying temperature detection control method and clothes drier

The invention discloses a clothes drying temperature detection control method and a clothes drier. In the process of drying, a control system is used for detecting a change delta T of temperature of outgoing air in front and in rear of a condenser after drying, and determines whether the change of temperature difference of outgoing air before or after passing the condenser reaches a corresponding set value delta Tt_g or not; g is the weight of clothes to be dried; if the delta T is larger than or equal to the delta Tt_g or lasts for a set time T within a certain set value range, the clothes are dried and a heating device stops operating; after the heating device stops operating, a drying program proceeds and does not ends until the detected temperature of incoming air is lower than the set temperature; and in the process of drying, heat of humid hot air after being subjected to heat exchange with clothes and before being subjected to cooling and dehumidification is subjected to heat exchange with air which is subjected to condensation and dehumidification, and the preheated air subjected to condensation and dehumidification is heated again and led into the clothes to dry the clothes. Using the waste heat saves electric energy and time, temperature detection and determination are accurate, and drying efficiency is improved.

Photoelectric continuous liquid level measuring method and device

The invention provides a photoelectric continuous liquid level measuring method and a photoelectric continuous liquid level measuring device. The photoelectric continuous liquid level measuring method comprises the steps of driving a current sensor monomer from bottom to up to detect the light intensity fed back from the position of the sensor monomer under the control of a sensor module; carrying out analog-digital conversion on a voltage corresponding to the detected light intensity; determining the liquid position of the position of the current sensor monomer according to the corresponding relationship of a preset liquid level and the analog-digital data; and after the measurement of the liquid level of the position of other sensor monomers under the time-sharing control of corresponding sensor modules is accomplished, summarizing the liquid level of each sensor monomer to the front end of a transmitter interface through data transmission between modules; and obtaining a total liquid level of the current liquid after analysis and process and outputting the liquid level in specified interface mode. The device adopts the modular construction which is assembled and positioned freely according to the requirement of the measuring range, the applicability of different measuring ranges is improved, and the transportation is convenient; and furthermore, the real time self-correcting function is provided, and the capability of pollution resistance and shifting is improved.

InactiveCN102390951AEasy to transport and useEasy to transportHigh performance concreteAcrylic acid
The invention relates to an internal curing material of high-performance concrete and a preparation method thereof. The internal curing material comprises the following components in parts by mass: 100 parts of expanding agent, 1.0-5.0 parts of organic high water absorption material, 0-50 parts of inorganic water absorption material, 0-1.0 part of water-retaining agent and 0-10 parts of filler. The preparation method of the internal curing material comprises the following steps of: mixing a sodium hydroxide solution, acrylic acid and acrylamide according to a certain mass part, stirring, sequentially adding a cross-linking agent and an initiator, and preparing a acrylic acid/acrylamide copolymer through polymerization; drying, crushing and sieving a reaction product to obtain the organic high water absorption material; and mechanically mixing the water absorption material, the inorganic water absorption material, the expanding agent, the water-retaining agent and the filler to obtain the internal curing material of the high-performance concrete. Compared with the prior art, the concrete prepared by using the product provided by the invention has functions of water retaining, internal curing, crack resistance and the like, meanwhile, the strength and the durability of the concrete are not influenced, and the internal curing material has the main advantage that the concrete prepared by using the internal curing material still has favorable crack resistance under an extremely drought environment.
