Description

Technical Field

[0001] The invention relates to the technical field of bio-organic fertilizer fermentation, in particular to bio-organic fertilizer fermentation control equipment. Background Art

[0002] Organic fertilizers are mainly derived from plants and (or) animals. They are carbon-containing materials that are applied to the soil to provide plant nutrition as their main function. They are processed from biological materials, animal and plant wastes, and plant residues, eliminating toxic and harmful substances. They are rich in a large number of beneficial substances, including: a variety of organic acids, peptides, and rich nutrients including nitrogen, phosphorus, and potassium. Organic fertilizer fermentation refers to the process of converting waste organic matter into fertilizer through the fermentation of microorganisms under certain water, C / N and ventilation conditions.

[0003] At present, the common biological organic fertilizer fermentation equipment on the market mainly adopts simple stirring and ventilation methods to promote fermentation. Some equipment controls temperature and humidity by manually adding water and adjusting ventilation, but this method is difficult to achieve precise control and has high labor intensity. Existing biological organic fertilizer fermentation equipment cannot achieve precise control of the fermentation environment, especially in terms of humidity control. It is often easy to add too much water at one time, resulting in a sudden change in humidity, affecting the growth of microorganisms, or adding water untimely, resulting in insufficient humidity, affecting fermentation efficiency. At the same time, in terms of temperature control, the heat generated during the fermentation process cannot be taken away in a timely and effective manner, resulting in excessively high temperatures affecting microbial activity.

[0014] Preferably, a feed hopper is fixedly connected to the top of the fermenter, and a baffle is rotatably connected to the top of the feed hopper.

[0015] Preferably, a discharge pipe is fixedly connected to the bottom of the fermentation tank, and a control valve is arranged outside the discharge pipe.

[0016] Working principle: By opening the baffle on the top of the feed hopper, the raw materials required for the fermentation of biological organic fertilizer are put into the fermentation tank from the feed hopper. When the raw materials need to be stirred, the motor is started to drive the connecting rod to rotate, and then the multiple stirring plates on the outside of the connecting rod rotate inside the fermentation tank. The stirring plate continuously stirs the materials in the fermentation tank to fully mix the materials, ensuring uniform distribution of temperature, humidity and nutrients during the fermentation process. It is also conducive to full contact between microorganisms and organic matter, accelerating the fermentation reaction speed.

[0017] When the humidity sensor on the top wall of the fermentation tank detects that the humidity is lower than the set value, a signal is sent to the water pump. The water pump starts, draws water from the water tank through the input pipe, and then transports the water to the connecting pipe through the output pipe. The water flows from the connecting pipe into multiple nozzles, and the sponge on the inner wall of the nozzle makes the water drip out slowly to avoid adding too much water at one time. The water drips into the material in the fermentation tank, increasing the humidity of the material.

[0018] The temperature sensor monitors the temperature in the fermenter in real time. When the temperature is higher than the set value, a signal is sent to the ventilation fan. The ventilation fan starts and draws air from the outside through the installation pipe. The air is filtered by filter screen three and then enters the ventilation pipe. The air enters the fermenter from the ventilation pipe through multiple delivery pipes, speeding up the air circulation in the tank, taking away the heat and lowering the temperature. Filter screen two can prevent the delivery pipe from being blocked. The one-way valve at the end of the ventilation pipe prevents the gas in the fermenter from backflowing.

[0019] When the connecting rod is driven to rotate by the motor, the bevel gear 1 on the outside of the connecting rod rotates accordingly. Bevel gear 1 meshes with bevel gear 2, driving bevel gear 2 to rotate, thereby causing the rotating rod to rotate under the support of the support block. The protrusion on the outside of the rotating rod rotates with the rotating rod, and when the protrusion contacts the moving plate, it pushes the moving plate to move upward. The moving plate drives the connecting rod and the slider to move upward, while compressing the reset spring 1. When the protrusion turns away from the moving plate, the moving plate, the connecting rod and the slider move downward under the action of the reset spring 1. The slider slides up and down in the installation box. When the slider moves upward, it opens the channel between the connecting pipe and the fermentation tank, so that the liquid fermentation agent in the storage tank intermittently enters the fermentation tank.

[0020] During the fermentation process, the pressure generated in the fermentation tank is transmitted to the connecting shell through the connecting pipe. The pressure acts on the movable plate, causing the movable plate to move upward, compressing the reset spring 2, and at the same time driving the pressure block upward to the pressure sensor. When the pressure sensor detects that the pressure exceeds the set value, it sends a signal to the solenoid valve. The solenoid valve opens, and the gas in the fermentation tank is discharged through the pressure discharge pipe to reduce the pressure in the tank. The filter screen 4 can prevent impurities from entering the pressure discharge pipe and filter the gas discharged from the fermentation tank. The one-way valve in the pressure discharge pipe prevents the external gas from flowing back.

[0021] After the fermentation is completed, the control valve outside the discharge pipe is opened to discharge the fermented biological organic fertilizer from the discharge pipe.

[0022] The present invention provides a biological organic fertilizer fermentation control device. It has the following beneficial effects:

[0023] 1. The present invention can transport water in the water tank to the fermentation tank through the cooperation of the humidity sensor and the water pump, realize the control of the humidity of the fermentation environment, and meet the specific humidity requirements of microbial growth. The sponge on the inner wall of the nozzle realizes the slow dripping of water, which not only prevents the sudden change of humidity caused by excessive water addition at one time, maintains the stability of the fermentation environment, but also improves the absorption efficiency of moisture by the fermented materials, and gives full play to the role of water resources. The combination of temperature sensor, ventilation pipe, delivery pipe and ventilation fan can introduce outside air into the fermentation tank in time. On the one hand, it speeds up the air circulation in the tank, effectively takes away the heat generated by the fermentation process, reduces the temperature, and prevents excessive temperature from causing adverse effects on the activity of microorganisms. On the other hand, it provides sufficient oxygen for microorganisms to promote the smooth progress of the fermentation reaction.

[0024] 2. The present invention drives the movement of the movable plate through the convex block and transmits it to the slider, which slides in the installation box, and controls the opening and closing of the channel between the connecting pipe and the fermentation tank through its position change, so that the fermentation agent control is more accurate and reliable, ensuring that the fermentation agent can intermittently enter the fermentation tank, avoiding the fermentation effect affected by excessive one-time feeding, providing a stable and appropriate supply of fermentation agent for the fermentation process, and effectively ensuring the quality and stability of biological organic fertilizer fermentation.

[0025] 3. The present invention transmits the pressure generated in the fermentation tank to the connecting shell through the connecting pipe. The pressure acts on the movable plate, causing the movable plate to move upward, compressing the reset spring 2, and at the same time driving the pressure block upward to approach the pressure sensor. When the pressure sensor detects that the pressure exceeds the set value, a signal is sent to the solenoid valve. The solenoid valve opens, and the gas in the fermentation tank is discharged through the pressure discharge pipe, reducing the pressure in the tank, ensuring that the fermentation process is carried out under a stable pressure environment, which is beneficial to improving the fermentation quality and consistency of the biological organic fertilizer.
