Abstract

The present invention relates to a solid organic waste material composting device for composting solid organic waste material. The solid organic waste material composting device is characterized in that the top of a compost barn is provided with a material feeding hole, a stirring shaft and an air exhaust pipe, and the circumference is provided with a double-layer side wall; constant temperature hot water is injected between the inner and the outer layers of the side wall by a hot water inlet pipe and a hot water outlet pipe which are connected with a constant temperature water tank to form a constant temperature hot water insulating layer; the side surface of the compost barn is also provided with a compost discharging hole, and the bottom is provided with a ventilating pipe, a liquid discharging pipe and a buffering layer; the stirring device comprises a motor, a stirring apparatus and a screen cloth, wherein the stirring apparatus and the screen cloth sieve are arranged in the compost barn; the stirring shaft is arranged in a stirring shaft hole through a bearing and connected with the motor to drive the stirring apparatus for stir; a ventilating system which comprises a blower and an air pipe and connected with the ventilating pipe through the air pipe. The solid organic waste material composting device has the advantages that the hot water is heated at constant temperature, ventilating air is controlled on the buffering layer to penetrate into compost uniformly, the stirring apparatus can make the feeding material of compost roll overall in the compost barn, the energy consumption is less, and the efficiency is high.

Description

A kind of composting device

Technical field: the present invention relates to the composting technology that solid organic waste substances is turned waste into wealth, particularly relate to a kind of composting device.

Background technology: common composting device is a storehouse formula internal heat type composting device, and well heater promptly is housed in composting device, and it has a significant deficiency, promptly very high in the well heater peripheral temperature, be easy to kill organism of fermentation, and the electromagnetic field that electric heater produces is unfavorable in the compost reaction.

Summary of the invention: the objective of the invention is provides a kind of have functions such as charging, air feed, temperature control, sampling, draining, exhaust, discharge, the external-heat composting device that space structure is reasonable, compact for making solid organic waste substances be converted into useful compost.

The present invention is design like this: it mainly comprises in-vessel composting system, ventilation system, stirring system, wherein: the top of in-vessel composting system is provided with opening for feed, stir shaft, vapor pipe, be equipped with double side walls around the in-vessel composting system, be connected with Water Tank with Temp.-controlled by the hot water water inlet pipe and water outlet pipe between the inside and outside two-layer sidewall and inject constant-temperature hot water, formation constant-temperature hot water thermal insulation layer; The side of in-vessel composting system also is provided with the compost discharge hole; Be provided with ventpipe, liquid discharge pipe, buffer layer in its bottom, stirring system comprises motor and is located at in-vessel composting system interior agitator, screen cloth that stir shaft is installed in to stir in the axis hole and with motor by bearing and is connected, and drives agitator and stirs; Ventilation system comprises blower fan and airduct, is connected with ventpipe by airduct.

The present invention has significant beneficial effect:

1, the present invention is provided with the constant-temperature hot water thermal insulation layer, carries out fluid heating and insulation to compost, and is can Yin Wendu very not high and kill organism of fermentation easily, and do not have electromagnetic field, can not produce any unfavorable of compost.

2, bottom of the present invention is provided with buffer layer, ventilation is delivered to buffer layer by the external source drum and is slowly entered in the compost material through ventilating hole channel, distinguished and admirable controlled and scatter and Jun Yun Di Seepage goes in the compost at buffer layer, it is strong, weak irregular and influence microorganism growth can not have strong impact or local ventilation.

3, whipping appts of the present invention is the agitator with the multiple tooth helical stir bar of 2-4 root, can effectively cover entire container, can stir comprehensively, mix thoroughly compost material, the power consumption less, the efficient height.

4, the ventilation buffer layer can be used as compost percolate tipping container again.Usually compost is anaerobism or the certain humidity of aerobic all need, and composting process also has large quantity of moisture to produce, the ventilation buffer layer has solved the problem of percolate sinuous flow as compost percolate tipping container, also can make simultaneously and keep certain humidity in the ventilation, help the compost reaction, improve whole plant efficiency.
