The crusher comprises a base, a movable bearing block, a static bearing block, a static tooth roller and a movable tooth roller, wherein the movable bearing block is connected with the static bearing block by a pull rod; the static bearing block is locked with the pull rod; the movable bearing block can move to and fro along the pull rod by an adjusting gearbox driven by a hydraulic motor and a worm and worm wheel mechanism; a movable bearing block slide is arranged on the base; a hydraulic locking cylinder is mounted on the base; a compression sliding block which can extrude the movable bearing block is fixed at the front end of the piston rod of the hydraulic locking cylinder; an encoder is mounted in the adjusting gearbox; and a displacement sensor is mounted in the hydraulic locking cylinder and is connected with a programmable logic controller (PLC) control system. The crusher has the advantages of simple structure, simplicity and convenience in operation, short adjustment period, high production efficiency and degree of automation and the like, and can be widely applied to the field of industrial crushing.

The invention relates to a laser radar coaxial transmitting and receiving system and a coaxial adjustment method thereof and belongs to the technical field of laser radar, and the method can be used for solving the problem that the coaxial adjustment period of a laser radar receiving and transmission light path is long. The laser radar coaxial transmission and receiving system is composed of a laser device, a transmission telescope, a first reflecting mirror, a second reflecting mirror, a receiving telescope, a concave lens, a convex lens, a beam splitter, an optical fiber, a CCD (Charge Coupled Device) camera, a computer and a motor rotation control system. The coaxial adjustment method based on the system comprises the following steps: adjusting the visual field definition of the receiving telescope; when the receiving telescope receives background light, obtaining a standard centroid position acquired by the CCD camera; starting the laser device, calculating the real-time centroid position of an image acquired by the CCD camera in real time, and calculating the deviation between the two centroid positions; and controlling the pitching and bearing of the first reflecting mirror until the deviation reaches an error tolerance, thus realizing the coaxial adjustment. The method provided by the invention is applicable to the coaxial adjustment of a laser radar receiving and transmission system.

The invention relates to the technical field of boiler combustion control, and provides a method and device for reducing nitrogen oxides produced by boiler combustion. Theoretical optimal ratio of gas and combustion aid, judge the adjustment object is flammable gas or combustion aid; adjust the intake speed of the adjustment object; obtain the ratio of nitrogen oxides, flammable gas and combustion aid in the exhaust flue gas again, and judge the nitrogen Whether the proportion of oxides increases; when the proportion of nitrogen oxides increases, stop adjusting the intake velocity of the adjustment object; adjust the intake velocity of flammable gases or combustion oxidizers in real time, so that the nitrogen oxides in the exhaust flue gas The proportion of the boiler can be reduced to a minimum, which can effectively reduce the emission of nitrogen oxides; each boiler can obtain the best combustion mode in its operating state, and improve the utilization rate of fuel, so it has strong universality.
