Specific characteristics and technical parameters of organic fertilizer fermenting tanks Hongjing Chen 1. Tank closure: The tank body is fully enclosed, and the exhaust gas produced by fermentation is treated by the exhaust gas treatment system to remove the tank and eliminate secondary pollution. 2. Insulation treatment: The interior of the tank is made of polyurethane as the insulation layer, which is affected by the outside world and ensures fermentation throughout the year. 3. Drive design: It adopts hydraulic drive and has large thrust, which can ensure the full load of the decomposed material in the tank, ensuring safe and reliable operation and low maintenance cost. 4, long life: all parts of the contact with the feces are made of 304 stainless steel, anti-corrosion, long service life. 5, electrical control: the use of PLC chip automatic and manual control system, easy to operate control. 6. Saving land: This equipment adopts three-dimensional design to save the land use area. At present, the commonly used method for treating livestock manure is traditional stacking fermentation, which is commonly used for open-air stacking and centralized indoor stacking. Open-air stacking is mainly carried out by tipping over the forklift to make full contact with the air to complete the fermentation; however, all livestock manures have a strong pungent odor before they are fermented, which is more serious to the air. When the turning operation is performed, the traditional mechanical turning operation is cumbersome, the irritating odor is generated, and the worker's body is also greatly damaged. Moreover, the land occupied by the stacking fermentation is relatively large, the fermentation cycle is relatively long, the efficiency of treating the manure is relatively low, and the labor input is large. There are certain seasonal restrictions on traditional stacked fermentation. When fermenting in winter, the temperature is relatively low and it is necessary to add certain insulation facilities. This has led to shortcomings such as prolonged fermentation cycle and increased investment. Third, the organic fertilizer fermenter technical content and beneficial effects The company's vertical fermentation equipment is mainly divided into internal fermentation materials and external thermal oil layer and insulation layer, and is equipped with a fully automated electrical control system. 1. As shown in the figure, firstly, the motor 1 is started to drive the high-efficiency reducer 2 to rotate, and then the coupling shaft 4 is driven to rotate by the coupling. After starting the motor, the material to be fermented is put into the interior of the fermenter through the feed port 3, while the spiral blade on the stirring shaft is turned over with the animal material, so that the material is in full contact with the air, and while being stirred, the material is continuously utilized through 11 High pressure enters the air and begins to enter the fermentation stage. 2. As shown in the figure, the heat transfer oil is added through the fuel filler port 6. During the material fermentation process, the electric heating device 9 intelligently heats the heat transfer oil heated at the bottom, enters the oil layer 7 through the communication pipe 10, and passes through the heat insulation layer. The insulation effect of 8 ensures that the internal fermentation material is fermented at a constant temperature. During the fermentation process, an appropriate amount of water can be added through the water adding device 13 to ensure the humidity required for the fermentation of the material. After the fermentation of the material is completed, the electric butterfly valve 12 is opened to discharge, and then the feeder 15 is used to assist the discharge. In addition, the equipment is also equipped with 14 pressure reducing device and 15 barrier device, heat transfer oil layer measuring device (oil level gauge), heat transfer oil layer protection device (safety valve). 3. Compared with traditional fermentation equipment, the equipment adopts vertical tank fermentation, which saves the land occupation area to a considerable extent; the equipment also adopts vertical electric heating device, intelligent electrical control to ensure constant temperature fermentation and completely solve The seasonal limitation of traditional fermentation equipment; intelligent electrical control, constant temperature fermentation, shortening the fermentation cycle from the traditional 15 days to about 10 hours, greatly improving the fermentation efficiency; the equipment is closed Constant temperature fermentation completely solves the problem of irritating odor volatilization and protects the environment from odor pollution; the equipment is equipped with a fully automatic intelligent electrical control system to reduce manual operation and ensure safety and reliability. 4. The beneficial effect of this environmental protection and practical type is: through the automatic electric appliance control system, the fermentation process of livestock and poultry manure is completed quickly and efficiently, and the artificial input is greatly reduced.
