The invention discloses a plant ash production and collection device, which can effectively perform centralized incineration treatment of wheat straws, treat generated flue gas and avoid smoke dust pollution, the incineration process is stable, efficient and completed, and the finished ash fertilizer has high purity. The device comprises an incineration kiln, a feeding device and a smoke purification device, wherein the incineration kiln is provided with an incineration inner chamber, and is inclined and forms an angle of 10-60 degrees with the horizontal plane; the incineration inner chamber is internally equipped with a transmission main shaft driven by a main motor; the transmission main shaft is equipped with a plenty of material spreading bodies used for stirring materials; and the incineration kiln is equipped with an air inlet, a smoke outlet part, a feeding port and a material cleaning start-stop door. The inventive device has good separation effect, can realize removal of solid particulates and dust in the flue gas, and dry raw materials by the use of flue gas waste heat so as to improve the subsequent incineration effect, and has a preheating structure which can well and fully ensure subsequent incineration.

A water-proof electronic caliber rule with digital indication is composed of displacement measuring device consisting of electric eddy sensors, metallic reflectors uniformly arranged on fixed rule by a certain wavelength, and several sensor coils installed on moving rule by a particular pitch. When an alternative current flows through said coils, an alternative magnetic field is generated in space to generate an electric eddy on said reflector. When fixed and moving rules move relatively, the magnetic field is modulated under the action of electric eddy, so measuring displacement value.

The invention discloses an incinerator for crop straws, and aims to provide an incinerator capable of effectively and intensively burning wheat straws, effectively treating flue gas and preventing smoke contamination caused by flue gas pollution, wherein a stable and efficient burning process can be ensured, the sufficient burning can be guaranteed and the purity of an ash fertilizer is high. The incinerator comprises an incineration kiln, a feeding device and a smoke purifying device, wherein the incineration kiln comprises an inner incineration cavity, the incineration kiln is inclined, an angle of 10-60 degrees is formed between the horizontal plane and the incineration kin, and the inner incineration kiln is provided with a driving spindle driven by a main motor; the driving main motor is provided with a plurality of material scattering bodies used for poking materials, and the incineration kiln is provided with an air inlet, a smoke outlet, a feeding hole and a purging opening and closing door. The incinerator provided by the invention has the beneficial effects of good separation effect, and solid particulate matters and powder in flue gas can be cleaned up; furthermore, raw materials can be dried by the waste heat of the flue gas, therefore the successive burning effect can be improved; in addition, the incinerator is provided with a preheating structure, and the subsequent incineration can be ensured more sufficiently.
