Description

Technical Field

[0001] The utility model relates to the field of garbage disposal devices, in particular to a solid-liquid separation type domestic garbage pre-filtering device. Background Art

[0002] Domestic waste refers to waste generated in daily life or in activities that provide services for daily life. The massive increase in domestic waste has made waste disposal increasingly difficult. Domestic waste often contains a lot of liquid. Therefore, a solid-liquid separation pre-filtration device is required for solid-liquid separation in waste disposal.

[0003] Most of the pre-filtration devices currently used use a filter mesh to complete solid-liquid separation, and then use a crushing device to further crush the solid waste for subsequent processing. However, the pre-filtration devices currently used generally pour the garbage from the top of the device, which requires manual lifting to a certain height to complete the dumping. The garbage itself has a certain weight, which greatly increases the intensity of manual labor. Manual lifting and dumping are also prone to spillage, which is inconvenient to use and has poor practicality, and is not suitable for promotion and use. Utility Model Content

The plate 17 is slidably connected to the water cylinder 16, the second cylinder 10 is connected to the sealing plate 13, the sealing plate 13 is slidably connected to the bottom of the water cylinder 16, the bottom of the water cylinder 16 can be closed by the sealing plate 13, the second filter box 9 is connected to the second drain pipe, the lower side of the second drain pipe is flush with the top surface of the connecting sealing plate 13, the bottom plate 4 is connected to the positioning block 11, the sealing plate 13 is in conflict with the positioning block 11, the bottom plate 4 is provided with a through hole 12, the top of the water cylinder 16 is connected to an open bucket 18, and the top surface of the pressure plate 17 is tilted downward.

[0025] The first filter box 1 is connected to a spring 3, the free end of the spring 3 is connected to the filter screen 2, the filter screen 2 is slidably connected to the first filter box 1, the first filter box 1 is connected to a drive motor 28, the output shaft of the drive motor 28 is connected to a rotating rod 29, the rotating rod 29 is connected to an eccentric wheel 5, the eccentric wheel 5 is in conflict with the filter screen 2, one group of rotating rods 29 is connected to two groups of eccentric wheels 5, and the two groups of eccentric wheels 5 are symmetrically arranged about the center line of the filter screen 2.

[0026] The eccentric wheel 5 is driven to rotate by the driving motor 28 , and the eccentric wheel 5 contacts the filter screen 2 . Since the spring 3 is provided, the filter screen 2 vibrates as the eccentric wheel 5 rotates.

[0028] When in use, start the drive motor 28 to vibrate the filter screen 2, start the servo motor 24 and the crushing motor 27, pour the garbage directly into the first filter box 1, complete the preliminary solid-liquid separation through the filter screen 2, and the liquid is discharged along the first discharge pipe 6, fixedly rolls along the filter screen 2 and then along the discharge port 26 and enters the auger transport pipe. The auger shaft 25 and the auger transport pipe cooperate to transport the solid garbage upward and then discharge it from the discharge pipe 23. The solid garbage moves along the discharge pipe 23 and then enters the second filter box 9 through the feed hopper 22. After entering the second filter box 9, it is crushed by two groups of crushing rollers 21. After crushing, it moves along the transition plate 20 and then falls into the water cylinder 16. At this time, the pressing plate 17 is located on the upper side of the open bucket 18, and the sealing plate 13 is located at the bottom of the water cylinder 16. Due to the crushing, part of the liquid squeezed out is discharged along the second discharge pipe 15.
