Description

LIQUID MANURE TREATMENT DEVICE

The proposed technical solution relates to the field of agriculture and can be used in animal husbandry for disinfection and drying of liquid manure.

A known installation for disinfecting liquid manure during high-temperature drying, containing consumable and pneumatic conveying tanks, combustion chambers, fans, cyclones, a condenser (Puzankov A.G. et al. Disinfection of effluents of livestock complexes. - M .: Agropromizdat, 1986, p. 94- 95).

The main disadvantage of the installation is the high cost of processing, as well as the mechanisms and units required; their creation of special large-sized workshops in which the equipment is installed.

The prior art pilot plant for disinfecting liquid manure with high frequency currents (Puzankov A.G. et al. Disinfection of wastewater from livestock complexes. -M.: Agropromizdat, 1986, p. 119).

The closest technical soup to the proposed device is the design of the combined microwave oven, containing heat treatment and drying chambers located one above the other in the housing and equipped with microwave sources, mechanisms for transporting the processed material, and interconnected by a transfer unit ( Pat. Of the Russian Federation No. 1758914, class П05В 6/64, 1992).

A disadvantage of the known microwave oven design is the cyclical nature of the process and the need to preheat the material to be processed using a heat generator in the heat treatment chamber, which increases the processing time and operating costs, as well as the inability to process liquid products.

The objective of the proposed technical solution is to ensure the disinfection of liquid manure and the production of high-quality organic fertilizer while reducing processing time.

The task is achieved in that the mechanism for transporting liquid manure in the heat treatment chamber is made in the form of a pipe laid horizontally in a spiral, and in the drying chamber in the form of a tray, along the bottom of which a screw conveyor is placed, while the reloading unit is made in the form of a mechanical separation device. In addition, the transportation mechanisms in the heat treatment and drying chambers are made of dielectric material, and the length of the spiral-shaped pipeline, the rate of advance of liquid manure along it, and the power of microwave radiation are selected from the condition of complete disinfection of liquid manure.

The figure shows a general view of the device.

A device for processing liquid manure consists of a housing 1 with perforation 2 in the upper wall and a partition of the housing equipped with microwave sources 5L1 (not shown).

In the lower part of the housing 1 there is a heat treatment chamber 3, into which liquid manure is fed through a supply pipe 4 into a spiral pipe 5 laid horizontally. The length of the spiral pipe 5, as well as the rate of advance of liquid manure along it and the power of microwave radiation are selected from the condition of complete disinfection of manure.

Above the heat treatment chamber 3 there is a drying chamber 6, in which a tray 7 with a screw conveyor 8 is located.

The spiral pipe 5 and the tray 7 with a screw conveyor 8 are made of dielectric material. Between the exit of the pipeline 5 and the entrance to the tray 6, a continuous mechanical separation device 9 is installed, for example, a centrifuge for separating decontaminated manure into fractions. Tray 7 with a screw conveyor 8 is equipped with an unloading unit 10 of dry organic fertilizer.

A device for processing liquid manure works as follows.

Under the influence of microwave radiation passing through the spiral pipe 5, liquid manure is heated and disinfected.

The disinfected liquid manure from the heat treatment chamber 3 enters the continuous mechanical separation device 9 (centrifuge), where it is separated into liquid and solid fractions. The liquid fraction is discharged to the drives for further use, for example, irrigation, and the solid fraction with a moisture content of 76-80% is fed into the drying chamber 6. By the screw conveyor 8, placed in the tray 7, the solid fraction is mixed, dried and fed to the discharge unit 10. Drying of the solid fraction manure occurs under the influence of microwave radiation and heat penetrating through the perforation 2 of the baffle of the heat treatment chamber 3. Evaporating moisture from the drying chamber 6 is carried out through the perforation 2 in the upper wall of the housing 1 of the device and exhaust ventilation is removed th (not shown in the figure). The solid fraction of manure thus dried is a high-quality organic fertilizer.

The proposed device is compact and can be performed in a modular-block version. Its use provides a continuous process of disinfection and drying of liquid manure, thereby solving sanitary and environmental problems.
