Description

Dry and wet beats control system and food refuse disposer

Technical field

The utility model is related to food-trash treatment field, more specifically, it relates to a kind of dry and wet beat control system and Food refuse disposer.

Background technology

According to statistics, China whole nation food remaining meal rubbish amount accounts for the 49% of rubbish total amount, and specific data are to have 13.4 ten thousand daily The food refuse of ton needs treatment, and the whole nation needs food refuse to be processed to amount to 49,000,000 tons within 1 year, and numeral is startling, at present China's kitchen garbage conventional treatment mode is buried to burn, and not only results in serious environmental pollution, and garbage decomposition efficiency Lowly, national year garbage disposal ability is only 8200 tons, garbage disposal ability and refuse production serious unbalance.

Therefore, technical staff have developed the food refuse disposer that can grind food refuse, and food refuse is smashed Drained by sewer afterwards, the research of Tongji University shows, rubbish is more easy to decompose by crushing, so it is great to smash food refuse Enhance the disposal ability of rubbish.

At present, the food refuse disposer of in the market process food refuse when, reference picture 1, common handling process bag Include procedure below：Step one：Start water inlet；Step 2：It is put into rubbish；Step 3：Polished；Step 4：Stop polishing after Continuous bath；Step 5：Stop bath and terminate polishing；The processor is being beaten by starting polishing after step one and step 2 During mill, food refuse is gradually smashed, and the particle and water of food refuse adulterate to form mixture, in the process food Garbage disposer constantly continues internally to wash by water and is gone out with by short grained food refuse, and polishing completes preprocessor and stops polishing Bath a period of time is cleaned, and finally terminates treatment.

Because food refuse disposer originates from foreign countries, and the foreigner eats be generally the quality such as bread, hamburger, potato compared with Soft food, even meat is also beefsteak, sausage, pure chicken after boning etc., so the side of above-mentioned food-trash treatment What method can be easily accomplished food smashes treatment.

But in eating habit at home, people focus on the nutrition in animal skeleton very much, the dish of meat bone one is often cooked Meat and fish dishes, polish these food refuses when, due to bone density compared with little Yi as the water in processor flows together, occur water and The mixture of bone fragments forms the situation of vortex in processor, and then the continuous sky of sanding apparatus of processor fetches water stream and nothing Method directly hits bone fragments, causes to continue that bone fragments are broken into fine particle, or bone fragments are beaten in appearance Into the situation that the fine particle used time is more long, the effect on driving birds is not good of polishing, therefore the food refuse disposer still have improved space.
