Description

Technical Field

[0001] This utility model relates to the field of biomass energy production technology, specifically a multi-stage anaerobic fermentation biomass energy production device. Background Technology

[0002] Bioenergy refers to energy derived from agricultural and forestry waste, industrial waste, and municipal solid waste, supplemented with additives such as charcoal powder, binding oil, and combustion aids. It includes biogas, bio-hydrogen, biodiesel, and fuel ethanol. Also known as green energy, bioenergy is derived from biomass and was one of the earliest energy sources utilized by humankind. In some concentrated dairy farming areas in my country, large amounts of manure are generated annually, which has long been difficult to manage effectively, resulting in resource waste. To improve manure treatment efficiency, a biomass energy production device is needed. However, existing biomass energy production devices still have the following shortcomings:

[0003] For example, the utility model with publication number CN221608050U discloses a fermentation device for biomass energy production and conversion. In this utility model, materials are poured into the fermentation tank by opening the feeding cover, and the motor is started to rotate the threaded rod and the stirring paddle to make the internal materials ferment evenly. The waste gas generated during the fermentation process will enter the incinerator through the waste gas pipe. After incineration, the waste gas is discharged into the air after being adsorbed by the activated carbon filter at the top, which can reduce the problem of waste gas being directly emitted into the air and polluting the air, thus making the daily living environment worse. The fermented material is discharged from the valve through the bottom hopper. However, similar to the prior art of the above application, when using existing biomass energy production devices, most biomass energy production devices are not convenient for quantitative and uniform feeding operations, which makes it easy for materials to spill during the transportation process. This affects the transportation efficiency and speed, and thus affects the overall processing progress, resulting in a decrease in the practicality and efficiency of the biomass energy production device.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and proposed a multi-stage anaerobic fermentation biomass energy production device. Utility Model Content

[0005] The purpose of this invention is to provide a multi-stage anaerobic fermentation biomass energy production device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-stage anaerobic fermentation biomass energy production device, comprising a receiving base and a feeding assembly. A main tank is provided on the upper left side of the receiving base, and a feeding assembly is provided on the upper right side of the receiving base. The feeding assembly includes a material placement frame, a feeding cylinder, a servo motor, a receiving rod, a conveying auger, and a discharge pipe. The feeding cylinder is provided on the left side inside the material placement frame, and a servo motor is installed in the middle of the upper end of the feeding cylinder. The front end of the servo motor is connected to the receiving rod, and a conveying auger is provided outside the receiving rod. A discharge pipe is provided on the upper left side of the feeding cylinder, and a reaction assembly is provided on the upper end of the main tank.

[0007] Furthermore, the feeding cylinder and the material placement frame are embedded in each other, and the feeding cylinder is fixedly connected to the material placement frame by bolts.

[0008] Furthermore, the external dimensions of the conveying auger are adapted to the internal dimensions of the feeding cylinder, and the outer side of the conveying auger is in close contact with the inner wall of the feeding cylinder.

[0009] Furthermore, the conveying auger is embedded in the feeding cylinder, and the conveying auger is rotatably connected to the feeding cylinder via a servo motor.

[0010] Furthermore, the reaction assembly includes a tank lid, a drive motor, a support rod, and a mixing plate. The drive motor is installed in the middle of the upper end of the tank lid, and the front end of the drive motor is connected to the support rod. The mixing plate is installed at the lower outer end of the support rod.

[0011] Furthermore, the reaction assembly also includes a baffle, a heating coil, and a polyurethane insulation layer. The baffle is added to the inner wall of the main tank, and a heating coil is installed inside the main tank. A polyurethane insulation layer is added to the outside of the main tank.

[0012] Furthermore, there are two mixing plates, and the two mixing plates are symmetrically arranged on both sides of the lower end of the support rod with respect to the central axis of the front of the support rod.

[0013] Furthermore, the internal dimensions of the polyurethane insulation layer are adapted to the external dimensions of the main tank, and the inner side of the polyurethane insulation layer is tightly fitted to the outer side of the main tank.

[0014] This utility model provides a multi-stage anaerobic fermentation biomass energy production device, which has the following beneficial effects:

[0015] 1.

This causes the conveying auger installed on the outside of the receiving rod to rotate inside the feeding cylinder, placing the cow manure to be processed into the material placement frame. The conveying auger then feeds the cow manure from inside the material placement frame and transports it to the main tank through the discharge pipe, thereby increasing the overall feeding convenience of the biomass energy production device.

[0016] 2. This utility model, through the setting of the reaction components, enables the multi-stage anaerobic fermentation biomass energy production device to operate by driving the support rod through the upper end of the tank cover to rotate, causing the mixing plate installed at the lower end of the support rod to rotate accordingly, and uniformly mixing the materials inside the main tank. The baffle increases the contact between the materials and methanogens, thereby improving the fermentation efficiency of the materials. The heating coil raises the reaction temperature inside the main tank, and the polyurethane insulation layer keeps the temperature inside the tank stable, improving the overall practicality and efficiency of the biomass energy production device.

The external dimensions of the conveying auger 305 are adapted to the internal dimensions of the feeding cylinder 302, and the outer side of the conveying auger 305 is flush with the feeding cylinder 302. 02 The inner walls are tightly fitted together. The conveying auger 305 and the feeding cylinder 302 are embeddedly connected, and the conveying auger 305 is rotatably connected to the feeding cylinder 302 via a servo motor 303. The feeding cylinder 302 is fixedly installed inside the left side of the material placement frame 301 by fastening bolts, so that there is a certain feeding distance between the feeding cylinder 302 and the bottom of the material placement frame 301. The servo motor 303 is fixedly installed in the middle of the upper end of the feeding cylinder 302, and the output shaft of the servo motor 303 is connected via a coupling. The device is connected to a receiving rod 304. The servo motor 303 drives the receiving rod 304 to rotate, causing the conveying auger 305 installed on the outside of the receiving rod 304 to rotate inside the feeding cylinder 302. The cow manure to be processed is placed into the feeding frame 301. The conveying auger 305 is used to feed the cow manure from inside the feeding frame 301, and then it is transported to the main tank 2 through the discharge pipe 306, thereby increasing the convenience of feeding the biomass energy production device as a whole.

[0023] like Figures 1 to 3As shown, a reaction assembly 4 is provided at the upper end of the main tank 2. The reaction assembly 4 includes a tank cover 401, a drive motor 402, a support rod 403, and a mixing plate 404.
