Automatic installation to control the subtleties of cement grinding in the stream

Automatic installation for monitoring the subtleties of cement grinding in the stream is a combination of an automatic analyzer and an automatic sampling device. The main technical functions that such an installation performs are: the selection of a representative test from the material pipeline; ensuring the transportation of samples to the analyzer without fractionation; Entering the sample into the analyzer; automatic analysis with a sufficiently high accuracy; A high degree of cleaning of all tracts of the sampling device, transport highways and analyzer after analysis. In the production for closing workshops, roller shutters are often used to order which you can: see. One of the most important requirements for creating such equipment is high reliability, since such an installation should work for a long time in a round -the -clock continuous mode. The installation consists of a sampling device, of the pressure line and the analyzer, which has a number of design features compared to the ATP-L1 analyzer described above. The action of the automatic installation consists of the following operations: selection of samples from the cement pipeline, landing in a self-supporting cyclone, transmission of a vibration-transmitter to the diffuser, dosing of a wire of 20 g on weights with a differential-transformer sensor, dawn in the pneumorassed, weighing the balance on automatic weights, fixation of the remainder using a scales sensor and a secondary device, cleaning all tracts with compressed air. In the initial position, air from the line 24 through the filter 26, the open valve 2 and the fence head / continuously passes into the cement wiring. Due to the fact that pressure "in the air line exceeds the pressure in the cement pipeline, the fence head is not clogged. The valve 5 is closed, and the pressure through the open valve 6 squeezes the valve 4. When the electromagnetic valve is triggered, the valve 5 opens, and the valve 6 closes. In this case, the valve 2 is squeezed, and the valve 4 opens. Cement through the fence tube 1, valve 3, valve 4, valve 7 enters the siege cyclone 8. This mode lasts 2-3 seconds.
