[0002] Stale domestic waste is also called mineral substance waste, which refers to the municipal domestic waste filled in landfill or accumulated for many years. The filled or accumulated waste not only causes serious environmental pollution but also occupies a lot of land, resulting in waste of land resources. Therefore, it is imperative to treat stale domestic waste. Since stale domestic waste is essentially domestic waste, the waste is discarded after being packed in plastic bags. These plastic bags are transferred to landfill or storage yard. Therefore, stale domestic waste contains a large amount of waste packed in plastic bags. These waste will be clumped together under the action of long-term sunlight or microorganisms, which is inconvenient for screening and treatment. The mechanical sorting equipment mainly uses a rotating cylinder to classify waste according to particle size.

[0003] In the existing cylinder screen, a simple crushing device is provided to preliminarily crush the blocky waste. The blocky waste is decomposed under the rotation of the cylinder and the stirring of the internal components. However, the cylinder screen cannot well cope with the strongly adhered waste (such as paper and fiber waste adhered together after being soaked in sewage for a long time) in stale domestic waste. The strongly adhered waste is easily clumped into larger clumps in the cylinder screen, which blocks the screen holes or affects the normal screening and treatment process of the waste.

A screen drum 5 is rotated inside the shell 2, and the outer end of the connecting rod 4 is fixedly connected to one end of the screen drum 5. A feed port is installed on the upper part of one side of the shell 2 above the motor 3, and a filter plate 6 is installed in the opening of the other end of the screen drum 5. The bottom of the shell 2 is inclined toward the other end to form a discharge port 7. This structure forms the basic framework of the drum screen, the support frame 1 provides stable support for the entire device, the shell 2 plays the role of protecting and accommodating internal components, the motor 3 serves as the power source, the connecting rod 4 drives the screen drum 5 to rotate, the feed port facilitates the entry of garbage, the filter plate 6 is used to filter, and the discharge The material port 7 is convenient for discharging the screened garbage. A spiral blade 8 is provided in the screen drum 5, and the spiral blade 8 is fixed on the inner wall of the screen drum 5. A plurality of cutting blades 9 are evenly installed on the circumference of the inner wall of the screen drum 5. The arrangement of the spiral blade 8 and the cutting blade 9 helps to process the garbage. The spiral blade 8 can push the garbage to move when the screen drum 5 rotates, thereby improving the fluidity of the garbage in the screen drum 5. The cutting blade 9 can cut and decompose the garbage. The cooperation of the two improves the treatment effect of stale garbage. The cutting blades 9 are evenly staggered along the length direction on the inner wall of the screen drum 5 between the spiral blades 8. This staggered distribution further improves the efficiency of garbage treatment. The garbage along the length direction on the inner wall of the screen drum 5 is fully cut and turned over to avoid dead corners in treatment, thereby more effectively treating stale garbage.

[0020] The utility model discloses that the cutting blade 9 is in the shape of a curved crescent, and the cutting tips of the cutting blades 9 are all facing in the same direction. The shape and direction of the cutting blades 9 help to improve the cutting effect, and the curved crescent shape can better fit the shape of the garbage for cutting. The knife tips facing in the same direction make the cutting smoother, thereby improving the garbage processing efficiency and improving the cutting accuracy and efficiency. The filter plate 6 is composed of two arc plates and a hinge shaft. The two ends of the hinge shaft are fixed on the inner wall of the screen drum 5. The connecting ends of the two arc plates are movably hinged by the hinge shaft. The upper and lower ends of the filter plate 6 are provided with a pressure component, and a plurality of filter holes are evenly opened on the arc plate. The filter plate 6 composed of the two arc plates can better adapt to the shape of the screen drum 5. The hinge shaft enables the arc plate to be movable. The setting of the opening and closing of the pressure component and the filter plate 6 makes it possible to automatically adjust the opening and closing state of the filter plate 6 by the action of the pressure component when encountering large-volume impurities. At the same time, the multiple filter holes on the filter plate 6 realize the removal of garbage. The filter plate 6 is opened and closed by the spring 11, and the filter plate 6 is opened and closed by the spring 11.

[0021] Working principle: When the present invention is used, stale garbage is poured into the screen drum 5 through the feed port above the motor 3, the power is turned on, the motor 3 is started, the motor 3 starts to run, and its output shaft drives the connecting rod 4 to rotate, thereby causing the screen drum 5 to start rotating. As the screen drum 5 rotates, the spiral blades 8 fixed to the circumference of the inner wall of the screen drum 5 push the garbage to move in the screen drum 5. At the same time, the cutting blades 9 staggered with the spiral blades 8 cut and decompose the garbage. The cutting blades 9 are in a curved crescent shape and the blade tips are all facing the same direction, which makes it possible to cut the garbage more effectively during the rotation of the drum. When the garbage moves to the filter plate 6 at one end of the screen drum 5, the normal-sized garbage is removed by the rotation of the screen drum 5 and the push of the spiral blades 8. The impurities are discharged from the outlet 7 at the lower end of the outer shell 2 through the filter holes on the filter plate 6, while the large-volume impurities that cannot pass through the filter holes are retained on one side of the filter plate 6. When large-volume impurities accumulate at the filter plate 6, the impurities exert pressure on the pressure components at both ends of the filter plate 6. After the pressure plate 10 in the pressure component is subjected to pressure, the connected spring 11 is compressed. The flexible protective cover outside the spring 11 prevents the spring 11 from being damaged. The snap-fit ​​protrusion 12 at one end of the spring 11 is disengaged from the snap-fit ​​groove inside the fixing blocks 13 at both ends of the screen drum 5. The two arc plates then rotate open around the hinge axis as the rotation point under the pressure of the object, and then the large-volume impurities are discharged from the screen drum 5. When it is determined that all the garbage has been processed, the power is turned off and the motor 3 stops running.

[0022] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
