The utility model discloses a sediment erosion prevention type eccentric semi-ball valve which comprises a valve body, a valve cover is fixed to the surface of the valve body in a screwed mode, a valve seat supporting ring is arranged in the valve body and installed on a step on the right side in the valve body, and a pressing plate is fixedly installed on the right side of the valve seat supporting ring. A spherical crown supporting plate is installed on the side, away from the pressing plate, of the valve seat supporting ring, a rubber sealing ring is arranged between the spherical crown supporting plate and the valve seat supporting ring, and a hemisphere is movably installed in the valve body. According to the sediment erosion prevention type eccentric half ball valve, due to the unique soft and hard double-sealing design, forward and reverse water inflow and the parabola-shaped water flow direction, two-way sealing is achieved, sealing zero leakage is achieved, the valve seat is designed to be of a floating structure, when the device is used, the device can be continuously used under the condition that overhauling is not needed, and after the overhauling period, the service life of the device is prolonged by replacing the rubber sealing ring. And long-term use can be continued.

The utility model relates to railway track technology, aims at providing a structure simplified embedded combined frog without using interval iron. The product includes wing rail located at both sides and heart rail located between wing rail, is equipped with one long strip alloy steel inlaying block respectively at both sides of heart rail, the opposite inner side of two alloy steel inlaying block roots and the two outer sides of heart rail root are all vertical plane, the alloy steel inlaying block is installed at both sides of heart rail in the mode of sticking all root extension section and partial rail head section to form sandwich structure, and is realized firm connection by multiple transversely -penetrating joint bolt pair, the sandwich structure is located between two wing rails, and is realized firm connection by multiple transversely -penetrating joint bolt pair, does not set up interval iron in the whole embedded combined frog. The core component of the product is relatively independent and firm in structure, can complete assembly in advance in factory, can guarantee installation quality, reduce on -the -spot construction workload, promote construction progress, save construction cost.

This utility model provides a furnace nose lifting device for continuous galvanizing production, including a furnace nose body, a mounting base, a dual-axis drive assembly, two opposing worm gear lifters, and two opposing tie rods. The two worm gear lifters are fixedly installed on both sides of the mounting base. The dual-axis drive assembly is installed on the top of the mounting base, and the output end of the dual-axis drive assembly is connected to the input end of the two worm gear lifters respectively. The output end of the two worm gear lifters is fixedly connected to the top of the two tie rods respectively. The bottom end of the two tie rods is fixedly connected to the outside of the furnace nose body. The two ends of the motor of this device are connected to the input ends of the two worm gear lifters respectively through cross-shaped universal joints. The dual-axis motor output ensures that the two worm gear lifters start simultaneously, avoiding the tilting of the furnace nose body due to insufficient power on one side. This device can expose the immersion section of the furnace nose to the zinc pot without stopping the production line, facilitating online replacement of the zinc pot.

This utility model discloses a timed cleaning device for a radar level gauge antenna in a dry distillation buffer silo. A desalination mechanism is installed on the radar level gauge's measuring connecting pipe. The outlet of the desalination mechanism's demineralized water flushing pipe passes through the radar level gauge's measuring connecting pipe. The demineralized water flushing pipe is equipped with a first shut-off valve, a first solenoid valve, and a second shut-off valve. The radar level gauge and the first solenoid valve are connected to a PLC. The desalination mechanism ensures that demineralized water can flush away coal dust and sludge from the radar level gauge antenna through the demineralized water flushing pipe. A nitrogen pipe and a first nitrogen purging pipe dry any residual water on the antenna. Third and fourth nitrogen purging pipes continuously blow air, maintaining positive pressure inside the first nitrogen purging pipe and the demineralized water flushing pipe to prevent coal dust backflow and blockage, and to prevent the timed flushing device from malfunctioning. Through timed cyclical purging, it is ensured that thick coal dust and sludge cannot accumulate on the radar level gauge antenna, allowing the radar level gauge to accurately measure the coal in the dry distillation buffer silo.

The invention discloses a preheater hot spot detection method and system, and relates to the technical field of preheater hot spot monitoring. Temperature signals of all measuring points on an air preheater are obtained, the temperature signals of all the measuring points are input to an intelligent fire judgment model, whether hot spots exist in the air preheater or not is judged, and finally the judgment result is transmitted to an embedded touch screen and a DCS; entering a human-computer interface through internal software of the embedded touch screen; the embedded touch screen carries out fire alarm through the color and state of a signal indicating lamp on the human-computer interface. The fire condition and the equipment state are judged according to the color and state of the signal indicator lamp; clicking the man-machine interface fault query button, the real-time data button, the historical data button and the parameter setting button to enter a corresponding sub-page, and clicking a return button to return to a previous interface; and when the fire alarm needs to be eliminated, the man-machine interface alarm elimination button is clicked to eliminate the alarm information. The reliability is high; the compactness is high; the maintainability is easy; and the real-time performance of hotspot detection is improved.
