Slurry filter press for kitchen garbage

Abstract

The invention relates to a slurry filter press for kitchen garbage. The slurry filter press for kitchen garbage comprises a rack, a worktable is arranged on the rack, a feeding chamber and a separating chamber are arranged above the worktable, and a screening net barrel is arranged in the separating chamber; a hollow stirring shaft is further rotationally connected inside the feeding chamber and the screening net barrel, and a plurality of exhaust holes are formed in the side wall of the part, located in the screening net barrel, of the stirring shaft; a hot air device is arranged below the worktable and comprises an air inlet pipe, heat exchange equipment, a draught fan, air dehumidification equipment and an air extraction pipe which communicate in sequence; the air inlet pipe communicates with the end, near the feeding chamber, of the stirring shaft, and the end, far away from the draught fan, of the air extraction pipe communicates with a first air extraction branch pipe and a second air extraction branch pipe; and the first air extraction branch pipe communicates with a discharging chamber, and the second air extraction branch pipe communicates with the separating chamber. Theslurry filter press for kitchen garbage has the effect of better dewatering and dehumidifying the kitchen garbage.

Description

technical field [0001] The invention relates to the technical field of kitchen waste treatment, in particular to a slurry hydraulic filter for kitchen waste. Background technique [0002] Kitchen waste refers to perishable organic waste such as fruits and vegetables, food scraps, leftovers, melon and fruit peels discarded in daily life. The composition of kitchen waste in China is complex. Kitchen waste is not only mixed with non-degradable substances such as plastics, metals and ceramics, but also has the characteristics of high moisture content, high salt and oil content, so it is not suitable for direct landfilling or disposal of kitchen waste. Incineration disposal. [0003] Before the food waste is landfilled, incinerated or biologically fermented, it is necessary to pretreat the food waste. The existing pretreatment process for the food waste generally includes crushing, screening and dehydration. First, the kitchen waste is crushed by the crusher, and then the plast...

Problems solved by technology

Although this treatment method can realize continuous feeding and discharging, and improve the efficiency of garbage dehydration treatment; however, during the rotation of the kitchen waste, the kitchen waste is Due to the action of force, the kitchen waste cannot rotate at the same speed as the helical blade during the lifting process, which makes the water and grease in the kitchen waste cannot be fully discharged; Dehydration treatment makes the dehydration treatment effect of kitchen waste poor
