2 Kitchen waste is also one of the main wastes in the restaurant. It is generated mainly after kitchenware processing and the scrap material remained in the diet after eating. Over the years, all businessmen are using the manual processes to clean and dispose the kitchen waste after the meal. In order to reduce the amount of labor of postprandial cleaning and kitchen garbage disposal, improve the efficiency and recovery rate of kitchen garbage treatment, we design a kind intelligent antiblocking sink which can better change the status of extensive use of manual processing. The device can achieve low output on the basis of existing business management that based on high input. THE OVERALL STRUCTURE AND FUNCTION The intelligent anti-blocking device comprises the inlet mouth connected with the device, solid-liquid separation roller, glue scraper, the outlet area of fan-shaped, double shaft structure, motors and other components. Through the optimizing design and computer simulation, the system structure of the anti-blocking sink is determined as shown in Figure 1. Figure 1. The overall structure of intelligent anti-blocking sink. 99

3 Processing Apparatus of the Intelligent Anti-blocking Sink Through treatment methods of the kitchen waste, processing apparatus of the intelligent anti-blocking sink is determined as the flow chart shown in Figure 2. Firstly, make the purpose to solid-liquid separation of the leftovers and other kitchen waste, in the case of leftovers and other kitchen waste are mixed into the antiblocking device. The solid shaft which is provided with the original power of the concentric double layer shaft structure is driven by a solid shaft to drive the roller to rotate through a high speed centrifugation to separate the solid and liquid. Through the cylinder wall, the water is discharged through a conical hole with a circular array distribution. In the drum has been basically eliminate the residual liquid solid leftovers and other kitchen garbage will discharge of the drum fan from the bottom. Secondly, in order to avoid without solid-liquid separation of leftovers and other kitchen waste discharge error. The opening of the fan-shaped at the bottom of the drum, the upper cover of the roller can be closed by the action of the fan-shaped. Figure 2. The diagram of the intelligent anti-blocking sink. Realization of the Function Imitating dehydration principle of the washing machine, through using a centrifuge drum device, dishwashing leftovers and other kitchen waste which form the pool into the sewers could be collected and recycled. Through the controlling of the PLC program, scraps and other kitchen waste in the drum unit could be rotated at high speed so as to realize solid-liquid separation. The water separated by the periphery of the drum would flow into the drainage system through the liquid guide layer. 100

4 The working principle of the Device is that, through the application of the weight sensor, when "weight of the kitchen garbage in the drum is more than 1kg", drum device would stop rotating. While upper of drum device is closed up so as to temporarily prevent the garbage from flowing into drum. And the anti-stick attached scraping board inside the drum turns on with opening of the fan-shaped in the bottom of the drum. In this way, solid kitchen garbage through the centrifugal processing would be putted into the specifically place that is used to put leftovers and recycled again. RESEARCH ON KEY TECHNOLOGIES OF ANTI-BLOCKING MECHANISM The intelligent anti-blocking sink could solid and liquid, recycle the scraps, emancipate the labor, increased the resource utilization, and so on. Structure of Concentric Double Shafts There are some structures that need the power conveyed through the motor-- roller and glue scraper. Through the double shaft structure, both of them could achieve asynchronous operation using dual-axis structure between different running. Double shaft is also named sleeve shaft. Solid shaft and hollow shaft are concentric, respectively, controlled by the rotor and the stator of motor so as to realize the separation control of the drum and glue scraper. The structure of double shaft is shown in Figure 3. Figure 3. The structure of double shaft. 101

5 Control Strategy of the Intelligent Anti-blocking Sink To ensure automation of the overall operation and integrity of all parts, we apply the PLC to control the actions of the opening and closing. While "weight of the kitchen garbage in the drum is more than 1 kg", the upper end of the drum unit is closed and roller fan-shaped at the bottom leaves open to guaranteed that sink in the solid-liquid mixture is not discharged accordingly during the discharge of solid scraps of kitchen garbage after centrifugation. Meanwhile, in order to ensure the efficiency of the device, closing at the top of the drum unit and fan blade at the bottom of the opening and the adhesion-proof scraper to turn these three actions work at the same time. Part of the PLC program code is shown in Figure 4. Figure 4. Part of the PLC program code. Properties of the Anti-blocking Sink Easy to install, moderate area under the sink washing dishes, direct access to the drain, without affecting the original kitchen sink's structure. Easy to operate, safe and reliable equipped with a push button switch, just tap the button, the device is run according to the PLC program, and no leakage risks, ensure sealing performance and reliability. Economic and environment-friendly when the power is 220V, frequency is 50Hz and the output of the device of the AC servo motor is 10W, the electricity fee 102

6 it costs by running 1 hour 0.01KWx1hx136.80/KWh=1.368 (Guangzhou City, according to general industrial peak and Valley electricity price list-version peak, electricity consumption for more than 35,000 volts and calculation). Clean and healthy--kitchen staff with scraps from the kitchen could realize the "zero" contacts. THE UTILITY VALUE OF ANTI-BLOCKING MECHANISM The intelligent anti-blocking sink is a sort of kitchen electrical which is modern new type of environmental protection. It was installed in the under of restaurant to wash the dishes sink and it is applied to separate the leftovers which are mixed with water and other kitchen garbage. It can improve the leftovers and other kitchen garbage's use ratio, avoiding leftovers and kitchen garbage sewer blocked, simplifying the processing steps of the kitchen staff for disposing the leftovers and other kitchen garbage to reduce the workload and liberate the workforce. What's more, it can reduce mosquito breeding to improve the kitchen health level and lower the merchant operating costs by reason of disappearing for the phenomenon of the leftovers and kitchen garbage's accumulation. The number of mess, eatery, food stalls or ristorante and so on, only to rise. Meanwhile, the popularity of commercial and residential dishwashers are rising steadily. Familiar with the Midea, Little Swan, Siemens, Galanz, etc. All into the dishwasher market. Particularly, the annual output of Galanz dishwasher up to one million. But, the use of dishwasher requires user to clean the filter of it every ten days. And dishes need to clean up food debris to prevent clogging blocking filter and so on. The use of this aptitude water channel anti-blocking mechanism will solve these problems of dishwasher. Furthermore, dishwasher does not need to set filter to reduce the production cost of it in the further. CONCLUSIONS The intelligent anti-blocking mechanism for leftovers and other kitchen waste for solid-liquid separation timely and so on, scraps and other kitchen waste can be recycled, low power consumption, high degree of automation, a good solution to a restaurant after dinner cleaning and leftovers, such as kitchen garbage accumulation, to make up for the gaps in the market. Run through the computer simulation, sample preparation, the intelligent anti-blocking sink works well whose indicators can meet the design requirements. 103
