Abstract: The invention provides a heat-storage medium conveying system for a solar-thermal power plant. The system includes a high-level tank subsystem including a high-level tank used to store the heat-storage medium. The system further includes a heat-storage medium transport subsystem. The high-level tank subsystem is connected with the heat-storage medium transport subsystem. The heat-storage medium transport subsystem includes a low-level tank. A mounting height of the low-level tank is lower than that of the high-level tank. A volume of the low-level tank is smaller than a volume of the high-level tank. The heat-storage medium can enter the low-level tank from the high-level tank partially or completely by its own gravity. The low-level tank is provided with a conveying pump, and the heat-storage medium is pumped out of the low-level tank through the conveying pump.

Abstract: A bowl flushing control device of low tank type toilet has a water supply pipe with a working chamber; a waterway switch component used to open and close the waterway of the water supply pipe; a first floater being floatable in the toilet tank, the first floater takes action when the water level in the water tank is lower than the working level; a control rod being movable up and down, the first floater is movably coupled to the control rod; the control rod is movably connected to the waterway switch component to move downwardly and drive the waterway switch component to close the waterway of the water supply pipe when the first floater takes off restriction on the control rod; a activation component used to control the control rod to move upwardly to reset and coupled to the control rod.

Abstract: A system for continuously preparing coated particles in a large scale comprises: a coating furnace, a cooling facility, a solid by-product treatment device, and a gas by-product treatment device connected in sequence. The coating furnace is used for coating particles. The cooling facility is used for cooling the coated particles. The solid by-product treatment device is used for treating solid by-products generated in the coating furnace during the particle coating process. The gas by-product treatment device is used for treating gas by-products generated in the coating furnace during the particle coating process. The system for continuously preparing coated particles resolves the problem that a system in the prior art, aiming at batch production, has a time interval between two batches, wherein a temperature increase process and a temperature decrease process both exist, and is small in scale, does not completely break through laboratory research and cannot achieve real industrial continuous preparation.

Abstract: A spherical fuel element forming apparatus comprises a fuel area forming system, a fuel-free area shaping system and a green sphere pressing system connected sequentially. The fuel area forming system is used for evenly mixing a core sphere matrix powder with nuclear fuel particles and then pressing the mixed core sphere matrix powder and nuclear fuel particles into core spheres. The fuel-free area shaping system is used for preparing a spherical fuel element from the core spheres covered by a fuel-free matrix powder. The green sphere pressing system is used for pressing the spherical fuel elements into green spheres. The spherical fuel element forming apparatus is distributed according to a technical process flow line operation, and is compact in structure and convenient to operate. Sphere greens after being finally pressed are high in sphericity, fuel element cost is lowered, and the finished product rate is high.

Abstract: Disclosed is a bowl flushing control device of low tank type toilet, which comprises: a water supply pipe with a working chamber; a waterway switch component used to open and close the waterway of the water supply pipe; a first floater being floatable in the toilet tank, the first floater takes action when the water level in the water tank is lower than the working level; a control rod being movable up and down, the first floater is movably coupled to the control rod; the control rod is movably connected to the waterway switch component to move downwardly and drive the waterway switch component to close the waterway of the water supply pipe when the first floater takes off restriction on the control rod; a activation component used to control the control rod to move upwardly to reset and coupled to the control rod. The first floater of the present invention directly senses the height of the water level in the tank, none business with the inlet pressure of the inlet valve.

Abstract: A method for the production of spherical combustible or fertile material particles from an oxide of the group of the heavy metals uranium, plutonium, or mixtures thereof. For this purpose, the process steps of producing a base solution of the nitrates of the heavy metal(s), adding at least one first reagent in order to adjust the viscosity of the solution, dropping the solution to form microspheres, at least superficially solidifying the microspheres in an atmosphere containing ammonia, collecting the microspheres in a solution containing ammonia, and subsequent washing, drying and thermal treatment are carried out, where at least one of urea, ammonium carbonate, ammonium hydrogen carbonate, ammonium cyanate, and biuret are added to the base solution before adding the first reagent. The solution thus prepared is heated to a temperature T where 80° C.?T<Ts and where Ts=boiling temperature of the solution, and is maintained at the temperature over a time period t where 2 h?t?8 h.
