In the description of the present invention, the terms "upper", "lower", and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for convenience of description of the present invention, but do not require the present invention to be constructed and operated in a specific orientation, and thus, cannot be construed as limiting the present invention.

Referring to fig. 1 and 6, the winter garbage pit device of the present invention includes a garbage pool 1, and a discharge opening 5 and a counter-blow nozzle 4 are disposed on a side wall of the garbage pool 1. The garbage on the garbage truck enters the garbage pool 1 through the discharge opening 5. The counter-flushing nozzle 4 is used for spraying hot water into the garbage pool 1. The utility model discloses in, the slope of hedging spray tube 4 is arranged, and the mouth of pipe of hedging spray tube 4 is towards the rubbish that gets into from discharge opening 5. So, form the offset from 4 spun hot water of offset spray tube and from between the rubbish that discharge opening 5 got into to will ice lump rubbish rapid heating break up, do benefit to melting of ice lump rubbish.

The utility model discloses in, the offset spray tube 4 forms the offset to the ice rubbish that sticks together to make ice rubbish that sticks together melt fast, thereby ensure the fermentation time of rubbish, and then ensure the stability of furnace temperature.

The utility model discloses in, will offset spray tube 4 and discharge opening 5 setting on the same lateral wall of rubbish pond 1. The thrust nozzle 4 is located below the discharge opening 5, and the thrust nozzle 4 is arranged obliquely upward. So, from the oblique upward motion of 4 spun hot water of hedging spray tube, from the oblique downward motion of rubbish that discharge opening 5 got into, hot water can fully contact with rubbish, has optimized the hedging effect, does benefit to ice lump rubbish and melts fast.

The hot water in the thrust nozzle 4 comes from a hot water pipe, and a control valve 15, a hot water pump 14 and a heater 13 are arranged on the hot water pipe. The heater 13 is used to heat hot water. The hot water pump 14 directs the hot water pump 14 towards the thrust nozzle 4, so that the hot water sprayed from the thrust nozzle 4 has a better initial velocity, which facilitates the hot water to be sprayed obliquely upwards.

In normal conditions, several of the discharge openings 5 can be used for discharging. When the garbage amount suddenly increases, the using amount of the discharging opening 5 can be increased so as to improve the discharging efficiency.

Referring to fig. 4, the distribution of the bottom of the garbage pool 1 is described as follows: the bottom of the garbage pool 1 is divided into a drainage area, two fermentation areas and a stacking area. The drainage area is adjacent to the discharge opening 5 with respect to the fermentation area and the accumulation area. Since the most effective accumulation region in the waste pool 1 is the two end regions in the length direction of the waste, the two end regions are set as fermentation regions. The accumulation area is positioned in the middle of the two fermentation areas. The garbage stored in the fermentation area can directly enter the incinerator for incineration after fermentation, the areas of the fermentation areas on the two sides account for 1/10-1/3 of the total area of the fermentation area and the accumulation area, and the remaining larger area is the accumulation area.

Ice lump garbage enters the back from the discharge opening 5, is unfrozen rapidly under the opposite flushing effect of the opposite flushing spray pipe 4, and then the garbage falls into the drainage zone nearest to the discharge opening 5 to be drained. The drained garbage is moved to a stacking area by the grab bucket 19 to be stacked, and meanwhile, the grab bucket 19 selects a part of the garbage in the stacking area to be moved to a fermentation area to be fermented.

The garbage fermentation process is actually a process of biological bacterium propagation, temperature rise, decomposition of organic matters in the garbage, continuous discharge of most of water in the garbage, and formation of garbage leachate by the discharged water. The water content of the garbage which is really fermented is about 20 percent basically, the obvious dripping phenomenon can not occur when the garbage is fed into the furnace, and the furnace temperature of the subsequent incineration working condition is relatively stable and easy to control. The moisture content of the garbage which is not fermented is far more than 20 percent, the garbage often has obvious water dripping or water flow phenomenon when entering the incinerator, the subsequent incineration working condition is greatly influenced, the temperature and the power generation load of the incinerator are reduced in a cliff-breaking manner, and the operation personnel can not control the garbage in time.

Referring to fig. 2, in order to rapidly ferment the garbage in the fermentation area, the heating pipe is disposed at the bottom of the fermentation area.
