Static electricity eliminator

Abstract: The utility model relates to a static electricity eliminator which is mounted on a bell mouth and used for solving the problem that static electricity carried by a tow affects the product quality of the follow-up process. The static electricity eliminator comprises a copper rod, and the copper rod is fixed on the bell mouth. In order to enable the mounting and the use to be more convenient and more rapid, the copper rod can be arranged in the shape of L; a fixing plate, a sheathing plate and a base can be increased between the copper rod and the bell mouth, the fixing plate is fixed on the base, and the fixing plate and the sheathing plate are connected with the copper rod through a connecting rod, wherein a round hole which can be sheathed on the bell mouth is formed on the sheathing plate. When in use, the static electricity eliminator is mounted on the bell mouth of a stretch breaking machine, when the tow passes through the copper rod, the static electricity carried by the tow is eliminated and a guarantee is provided for the product quality of the follow-up process.

Lower end fitting with multistage flow diffusers

Abstract: An improved lower end fitting 10 (LEF) having a bell mouth multistage type of flow jet diffuser 30 with stages 31, 31' decreases pressure drop 15-20% over a single stage bell mouth diffuser and more evenly distributes flow and adds strength It includes neutron thimble flux impingement shield 50 of instrument and/or cable Each diffuser stage 31, 31' is SS, of circular cross-sect and parabolic to optimize diffusion The multistage shape is based on lower core plate 20 flow hole 24 geometry, LEF design and reactor flow rate Thinner LEF legs 36, smaller LEF gussets 38 and thinner LEF flow plates 22 are possible

Installation of omnibearing wind collecting cap

Abstract: This invention relates to an amnibearing wind-collecting cover device composed of four bell mouths collecting wind energy at water level, a central shaft and a semispherical wind wheel and a shift driver, in which the four bell mouths are face to face in pairs towards all directions to form an inlet and an outlet connected at the central shaft, the inlet of bell mouth 3 is facing to the semispherical wheel, the shift driver is connected with the central shaft at a base, in which the bell mouths can collect wind energy in all directions to rotate the semispherical wheel, the diameter of which is small, vibration is less and operation is stable, the wind cover can increase power of wind generators by enlarging diameter of bell mouths to increase collection area, and can be made to a tower or a wall for placing all devices, especially suitable for mountain areas.

Connecting device of plastic pipe and inspecting well

Abstract: The utility model relates to a connecting device of a plastic tubular product and inspection chamber. The utility model is mainly applied in the connection of the plastic tubular product and the inspection chamber and comprises a plastic short pipe 2 which is connected with the bell mouth 1-1 of the side wall of the inspection well 1 and an inspection well 1. The utility model is characterized in that: the bell mouth 1-1 of the side wall of the inspection well 1 is provided with a water swellable rubber sealing ring 3. A mediation layer 4 is arranged between the water swellable rubber sealing ring 3 and the bell mouth 1-1 of the side wall 1. Due to the arrangement, the utility model can prevent water leakage due to invalid sealing caused by temperature changes or geology sedimentation which replaces the pipe sheet.

Three-aperture bell mouth for compact spinning

Abstract: The present invention relates to a three-aperture bell mouth for compact spinning, belonging to the technical field of textile machinery fittings. The three-aperture bell mouth is a square cone-shaped bell mouth and comprises a main square cone-shaped bell mouth body (2), wherein the upper mouth part of the main square cone-shaped bell mouth body (2) is forward inclined in shape, and the bottom is equipped with three yarn holes (4). Two clapboards (3) among the three yarn holes are arranged in an inverted 'V' manner just to separate the three yarn holes (4). The three-aperture bell mouth for compact spinning, according to the present invention, is advantageous in saving manpower and reducing energy consumption.
