Rubbish dehydration solid-liquid separation device

Abstract

The invention discloses a rubbish dehydration solid-liquid separation device. The rubbish dehydration solid-liquid separation device comprises a closed solid-liquid separation cylinder body, a downward-moving hydraulic system with a lower push plate, a discharging hydraulic system with a discharging push plate and an upward-moving hydraulic system with an upper push plate. A feeding opening and a discharging opening are formed in the upper portion of the solid-liquid separation cylinder body. The lower push plate of the downward-moving hydraulic system is arranged on the top of the solid-liquid separation cylinder body and can move up and down along an inner cavity of the solid-liquid separation cylinder body. The upper push plate of the upward-moving hydraulic system is arranged at the bottom of the solid-liquid separation cylinder body and can move up and down along the inner cavity of the solid-liquid separation cylinder body. The discharging push plate of the discharging hydraulic system is arranged at the position, corresponding to the discharging opening, of the solid-liquid separation cylinder body, and can make transverse movement along the inner cavity of the solid-liquid separation cylinder body. According to the rubbish dehydration solid-liquid separation device, a double-direction vertical hydraulic squeezing mode is adopted, powerful squeezing can be provided, the problems of winding and hard object sticking in material dehydration can be solved, the adaptability to materials is high, the effects of rubbish reduction and volume reduction are obvious, the automation degree is high, and sealed deodorization can be achieved.

Description

technical field [0001] The invention relates to a garbage dehydration solid-liquid separation device, which belongs to the technical field of domestic garbage treatment. Background technique [0002] Kitchen waste is collected by households and communities, hotels, restaurants and other catering units discard raw waste with high water content and high organic matter content before and after meals, expired food in supermarkets, and various vegetable leaves and fruits produced in farmers' markets. Collectively, this part accounts for about 50-65% of the amount of domestic waste, and is an important part of domestic waste. [0003] Compared with domestic waste, kitchen waste has the following characteristics: 1) The content of organic matter such as crude protein and crude fiber is relatively high, and it is perishable and odorous; 3) low calorific value, which limits the application of incineration technology. [0004] The traditional main treatment methods of kitchen waste ...

AI Technical Summary

Problems solved by technology

However, the current classification and collection of kitchen waste is not ideal. Many materials that do not belong to kitchen waste also enter the treatment system, such as plastic bags, lunch boxes, paper, chopsticks, cutting boards, broken kitchen knives, torn clothes, and ropes. There are even kimchi jars, table legs and chair legs, etc. Therefore, the above-mentioned rotating equipment is often entangled by plastic bags, fabrics, ropes, etc., hard objects are stuck, etc., equipment failures continue, and the system cannot operate normally and stably
