Abstract

The utility model relates to an organic solid waste composting reactor with a stirring gear and an adsorption layer, which can be used in composting treatment for organic solid waste. The reactor comprises an insulation layer, a gas collection layer, a packing adsorption layer, a gas inlet buffer layer, a rotating shaft, a stirring gear, an intake pipe, a drain pipe, a discharge hole, an exhaust port, a connecting removable cover and a space surrounded by the insulation layer. The utility model is provided with a removable cover, and the packing adsorption layer inside the removable cover can freely replace the odor adsorbent, thereby the composting odor can be prevented from being escaped; the rotating shaft and the stirring gear can mix and stir the composting materials intermittently to avoid the materials agglomerated, and ensure a good stirring to the solid particles and is conducive to ventilation, so the fermentation process can be speeded up and the fermentation cycle can be shortened. The utility model can solve the deficiencies the composting reactor of background art that the materials mixing is uneven with slow composting reaction speed and odor production.

Description

The organic solid waste compost reactor that has stirrer gear and adsorption layer

Technical field

The utility model relates to a kind of organic solid waste compost reactor that has stirrer gear and adsorption layer.It relates to a kind of device that organic solid castoff can be carried out composting.

Background technology

Current, world resource and shortage of energy sources problem are more and more severeer, and along with world population increases and economic growth, the generation of organic solid wastes such as domestic refuse also increases severely with day.From the angle of material recovery and resource utilization, adopting composting method to handle organic solid wastes such as ight soil, organic domestic waste is the excellent means that meets circular economy concept.Composting device is the important carrier that windrow and compost reaction are carried out.Yet, can be used for organic waste processing of resident living sub-district and colleges and universities, scientific research institutions now and carry out composting such as ight soil, mud, organic waste to test employed commercialization compost reaction unit also fewer indoor; And the reactor of application exists reaction mass easily to mix inhomogeneous, problems such as speed of response slow, generation foul smell more on a small quantity, thereby has also limited composting method to a certain extent wideling popularize and practical application aspect the processing organic solid waste.

The utility model content

Main purpose of the present utility model is to provide a kind of organic solid waste compost reactor that stirrer gear and adsorption layer are arranged, and this reactor can be when realizing the organic solid waste composting, and appropriateness shortens reaction time, avoids the effusion of odorous substance simultaneously.

For achieving the above object, technical solution of the present utility model is: designed the organic solid waste compost reactor that has stirrer gear and adsorption layer, this device comprises that thermal insulation layer, gas collection layer, adsorption stuffing layer, air inlet buffer layer, turning axle, stirrer gear, inlet pipe, liquid discharge pipe, discharge port, venting port, removable cover connect the in-vessel composting system that the space constituted that reaches by the containing of thermal insulation layer inwall.The compost reactor main body selects for use synthetic glass or stainless steel to make cylindrical container; Select for use heat insulation, lagging material to make thermal insulation layer; The space that inwall contained of thermal insulation layer is in-vessel composting system; Adsorption stuffing layer and gas collection layer constitute Moveable lid body, the upper and lower pore screen cloth of respectively establishing of packing layer, and lower screen has spiral shell knob and lid inboard to join; The gas collection layer connects the top that venting port is located at Moveable lid body, and venting port is equipped with T-valve and links to each other with the external world; Screen cloth is also established in the in-vessel composting system bottom, and the screen cloth bottom is gas distribution and leachate collecting chamber (also claiming the air inlet buffer layer); Inlet pipe and liquid discharge pipe and air inlet buffer layer join, and all are with valve, at any time switch; The compost discharge port is located at the bottom of barrel wall, and the forms interlayer adds and fills lagging material, with sealing-ring the inside and outside wall of discharge port and reactor thermal insulation layer is combined closely; Make turning axle with weldless steel tube, welding double flow duct formula stirrer gear on turning axle.

After adopting such scheme, the utility model employing is heat insulation, lagging material is made thermal insulation layer, has reduced the calorific loss of compost; Have gas distribution and leachate collecting chamber (also claiming the air inlet buffer layer), establish inlet pipe, liquid discharge pipe and respective valves, can realize that compost oozes the timely collection and the guide of drop liquid; If Moveable lid body, its upper and lower pore screen cloth of respectively establishing of adsorption stuffing layer that lid is built-in, lower screen has spiral shell knob and lid inboard to join, and can realize freely the changing of foul smell sorbent material, thereby avoid the compost foul smell to overflow; Utilize turning axle and stirrer gear can stir and stir compost material off and on, prevent the material caking, guarantee good stirring, and help ventilating, thereby accelerate fermenting process, shorten fermentation period solid particulate.Overcome material in the compost reactor that background technology exists easily mix inhomogeneous, the compost speed of response slow, produce the defective of foul smell.

Description of drawings

Accompanying drawing 1 is the structural representation of the organic solid waste compost reactor of band stirrer gear and adsorption layer.

Embodiment

As shown in Figure 1, the organic solid waste compost reactor of the utility model band stirrer gear and adsorption layer, gas collection layer (1) and adsorption stuffing layer (2) constitute Moveable lid body, Moveable lid body links to each other with the inside and outside wall of reactor thermal insulation layer (4) by removable cover junction (9), the space that inwall contained of reactor thermal insulation layer (4) is in-vessel composting system, forced air is fed by inlet pipe (6), supply with the compost reaction via air inlet buffer layer (5) back, stirrer gear (3) is the double flow duct formula, by welding stirrer gear (3) is connected on the turning axle (11), turning axle (11) drives the thorough mixing of stirrer gear (3) realization to compost material under external force, and the drop liquid that oozes that produces in the composting process can be by liquid discharge pipe (7) guide in time that has valve; The gas that compost produces carries out odorous substance absorption after import venting port (10) by gas collection layer (1) by the adsorption stuffing layer (2) that is filled with the foul smell sorbent material earlier, and compost went out compost reactor clearly by discharge port (8) when reaction finished.The foul smell sorbing material of adsorption stuffing layer (2) filling is selected from gac, vermiculite, zeolite, matured compost, calcium chloride, calcium sulfate, magnesium chloride, sal epsom, manganous sulfate, trimagnesium phosphate and elemental sulfur; Turning axle (11) is made of weldless steel tube.

The utility model is established Moveable lid body, and the built-in adsorption stuffing layer of lid can be realized freely the changing of foul smell sorbent material, thereby avoid the compost foul smell to overflow; Utilize turning axle and stirrer gear can stir and stir compost material off and on, prevent the material caking, guarantee solid particulate is carried out good stirring, and help ventilating, thereby accelerate fermenting process, shorten fermentation period.Overcome that mixing of materials is inhomogeneous in the compost reactor that background technology exists, the compost speed of response slow, produced the defective of foul smell.
