Background

Composting is one of the main processes for treating organic wastes such as livestock and poultry manure. The current commonly used is traditional slot type composting technology, namely organic fertilizer wastes are placed in a long slot type structure for fermentation. The trough type composting has high mechanization degree, short composting period and high product quality, but the problem of odor pollution exists because the trough type is open. In recent years, a nano-film composting technology has been developed, in which livestock and poultry manure is covered and sealed with a nano-film to prevent odor substances from entering the atmosphere. However, the nano-film type compost has the defects of complex film laying and opening steps and labor consumption in the using process. In order to overcome the defects of the conventional organic fertilizer waste trough-type compost and nano-film compost, the application provides a telescopic nano-film covering trough-type compost facility.

Further, the nano-film is an expanded polytetrafluoroethylene nano-film.

Furthermore, adjacent upright posts are connected in a mode of hinged connecting rods.

Furthermore, two connecting rods are hinged between the adjacent stand columns and are arranged in a cross shape.

Furthermore, the parts of the nano-film at the two sides of the facility are fixed with the upright posts.

Furthermore, a ventilation opening is arranged on the composting facility and connected with a fan, and the fan ventilates the composting facility through the ventilation opening.

Furthermore, the ventilation opening is located on the concrete ground and connected with the fan through a pipeline buried under the ground.

Furthermore, a door for entering is arranged on the nanometer film, a magic tape is arranged on the door, and the door and the nanometer film are opened and closed through the magic tape.

Further, the wall body is "pi" shape, and ground slope is 1% to the opening direction slope of "pi" type groove.

Furthermore, a rainwater drainage ditch is arranged around the facility to prevent rainwater runoff from entering the storage facility.

Further, a motor is connected to the outermost upright post, and the motor drives the outermost upright post to move back and forth to drive the rest upright posts to move; the motor is connected with a controller.

Compared with the prior art, the utility model has the following advantages:

the periphery and the top of a telescopic nano-film covered groove type composting facility in the application are sealed by the nano-film, the nano-film can penetrate through air, carbon dioxide and water vapor, but pathogenic bacteria and macromolecular odor substances can be blocked by the nano-film and cannot pass through the nano-film. Therefore, the retractable nano-film covered trough type composting facility overcomes the defect that the trough type composting pollutes the environment.

In the application, the retractable nano-film covers the groove type compost livestock and poultry manure facility, the ceiling support with the slide way can be retracted through electric power, the automatic covering and lifting of the nano-film is realized, and the defect of overlarge labor intensity of film covering and lifting in the nano-film compost is overcome.

Detailed Description

The retractable nano-film covered trough type composting facility shown in fig. 1 and 2 comprises a concrete ground 1, wherein a wall body 2 is arranged around the concrete ground 1, and a retractable ceiling support is arranged above the wall body 2.

The ceiling support comprises a plurality of ceiling ejector rods 32 for supporting the top nano-film, each ceiling ejector rod is connected with an upright column 31, rollers 34 are arranged at the bottoms of the upright columns, and guide rails 21 matched with the rollers 34 are arranged on the wall body.

Two connecting rods 33 are hinged between the adjacent upright columns and are arranged in a cross shape.

The composting facility is provided with a vent 4, the vent is connected with a fan 5, and the fan ventilates into the composting facility through the vent. The ventilation opening is located on the concrete ground 1 and is connected with the fan through a pipeline 41 buried under the ground.

The parts of the nano-film positioned at the two sides of the facility are fixed with the upright posts.

The nano membrane seals the top and the side of the livestock and poultry manure facility, the nano membrane can be a 100% expanded polytetrafluoroethylene nano membrane produced by Jingmen Max agricultural science and technology Limited, the nano membrane is a selective breathable membrane, micro filter holes with the pore diameter of 0.2-0.3 mu m are uniformly distributed on the nano membrane, and the filter holes do not allow macromolecules to pass through, such as odorous gas molecules, biological aerosol and dust, and water vapor and carbon dioxide gas molecules can pass through the molecular filter membrane. Partial water vapor generated by excrement in the membrane forms a water film on the inner surface of the molecular filter membrane, and odorous gas molecules such as ammonia gas and hydrogen sulfide gas are very soluble in water, so that the odorous gas molecules are absorbed and intercepted by the water film on the inner surface of the molecular filter membrane, fall with the condensation of the water film, fall into compost and are decomposed by organic matters again, odor emission and ammonia loss are reduced, the nitrogen content of the organic fertilizer is improved, and the quality of the organic fertilizer prepared by composting fermentation is improved. Therefore, the molecular filter membrane has the functions of water resistance, moisture permeability, bacteria isolation, deodorization and the like.
