In terms of mechanical structure, the main body of the washing machine is a drum, and the rotation thereof can cause the materials in the drum to roll, rub each other and friction with the wall of the cylinder, thereby peeling off the surface dirt. However, these effects are only mechanically assisted in the cleaning operation. Therefore, such washing machines need to be combined with watering, spraying or soaking. Spray and immersion cleaners are therefore named. The drum is generally a round cylinder, but it can also be made into a hexagonal cylinder. First, the working principle of the drum cleaning machine The intermittently operated drum type washing machine is provided with a baffle plate at both ends, and an inlet and outlet port with a cover plate is opened in the circumferential direction. When the material port is upward, the material inlet cover can be opened to feed inward; after washing, the cylinder body is turned to the material opening and the material can be discharged. In order to facilitate the material to roll in the cylinder, the feeding should not be too full. Generally, such a washing machine uses a spray pipe to spray water continuously or intermittently into the cylinder to infiltrate the dirt and quickly peel and discharge. The rollers of the continuous drum cleaner are open at both ends, and the raw materials enter from one end and the other end. The axial movement of the material in the cylinder can be achieved by tilting the cylinder or by providing a spiral guide or copy board on the inner wall of the cylinder. In order to improve the cleaning effect, some drum type cleaners are equipped with brushes that can be adjusted up and down and left and right. Second, the application of the drum cleaning machine The material enters and falls into the drum from the feeding hopper. As the drum rotates, it continually rolls and rubs against each other in the drum. Together with the washing of the spray water, the dirt and mud sand on the surface of the material fall off, and the screen hole of the drum is used. The spray water is discharged through the drain. The raw material entering the cleaning tank from the feed port is first cleaned in the vortex generated by the two rotating brush rolls. At the same time, since the gap between the two brush rolls is narrow, the water flow between them has a higher flow rate and the pressure is lowered. The cleaning material is further brushed by a brush roller under the pressure difference and the friction of the brush roller. Then, the material to be cleaned is further sprayed and cleaned by high pressure water in the dumping bucket. Third, the characteristics of the drum washing machine The bottle that enters the machine from the bottle end is washed by pre-rinsing, pre-soaking, detergent soaking, detergent spraying, hot water pre-spraying, hot water spraying, warm water spraying and cold water spraying, and finally leaves the bottle from the bottle end. Bottle machine. The pre-flushing is to remove the dirt attached to the outside of the bottle to reduce the amount of washing liquid in the back. The wash spray zone is located above the wash tank so that the wash liquor drained from the bottle returns to the wash tank. The sterilized empty can is finally sent to the can exit rail by the third star wheel to enter the canning process. The empty can has a certain inclination when it is rotated in the washing machine, so that the water in the tank can flow out. Sewage is discharged into the sewer by drain pipe
