I. Introduction: the drum washing machine is especially suitable for mixed silt debris more potato root class coarse wash process (ie, the first cleaning), is widely used in fruit and vegetable processing industry, has a simple structure, coarse wash thoroughly, easy operation and maintenance of Features. Material through the end of the rotary drum hoist from entering, material uninterrupted angle iron hit the inner wall of the drum in the drum, shake off the attached material surface sediment, debris, mixed in the material of the nails, stones, Zhasi and so on down the angle iron fall under the arc gap wash sink, and gradually sinking into a sump, regular emissions. With spiral fan blade material will be cleaned from the other end of the drum launch into the next process. Second, the main parameters: processing capacity: 3000-5000kg / h roller diameter: ￠ 900 residence time: 40 seconds to 3 minutes (speed or variable frequency electromagnetic governor) water consumption: 1.5-2M3 / h Total power: 3KW inlet height from the ground 1630 spout height from the ground 1165 Dimensions: 4000 × 1250 × 1850 Third, install the machine shipped to the designated location, properly adjust the height of the body, in order to reach the front lines of convergence, to ensure a smooth device itself . Former aircraft factory commissioning normal, on-site installation in place, by a team of officers responsible for the installation and maintenance throughout the bolt is loose. Pulled by hand from the discharge end of the drum is rotating flexible. Then try energized, check for abnormal noise, check drum rotation direction (counterclockwise) is correct. If the opposite direction of rotation, stop immediately after the exchange of three-phase power test terminals. After the installation procedure is complete, before the official power run. Fourth, the operation of the ride is generally in the production line is running. Start with the water hole to sink filled with water, and then press the roller drive motor of the "Start" button, the drum began to operate smoothly. Depending on the material and production process requirements, appropriate adjustments to the inverter frequency (or electromagnetic speed control knob) that is changing the speed of rotation of the drum. Empty the entire production line running normally, you can feed production. As found in unusual aircraft inspections, immediately press the "Stop" button (or "emergency stop" button), stop-check after troubleshooting, before use, to avoid equipment damage or difficult to repair. At the end of production, to obey the order of the entire production line shut down, and shut down the aircraft's "Stop" button. V. Maintenance: It is in addition to regular maintenance of machinery and equipment in general, the result of the accumulation of coarse sediment washing process more dirt, and sometimes spill over the sump, except when the transfer class door open sewage discharge, the best Open the cover (lid or without customized by the customer), rinse with water cannons under the arc cleaning tank, attached to exclude sludge tank and sump cleaning combined unit.
