It combines hydrothermal treatment, enhanced swirl mixing, and multi-stage synergistic reaction technologies. The goal of this type of device is to improve the efficiency of biogas slurry treatment, resource recovery rate, and the quality of final products such as fertilizer and energy. The "hydrothermal multi-stage swirl mixing and synergistic reaction device for biogas slurry" represents an advanced and highly engineered biogas slurry treatment technology route. It uses hydrothermal energy to provide the core reaction power, utilizes multi-stage swirl mixing to achieve highly efficient intensification of the reaction process, and optimizes reaction conditions and energy utilization through multi-stage series connection, ultimately achieving deep synergy among the three elements. It aims to solve the biogas slurry treatment problem in a more efficient, energy-saving, and resource-efficient manner, promoting the sustainable development of biogas projects and the recycling of biogas slurry.

[0003] Existing hydrothermal slurry mixing reactors mostly use hydrocyclones for mixing, but the liquid only rotates in one direction, which leads to insufficient mixing and inconvenience in use.

[0004] Therefore, there is an urgent need to propose a multi-stage swirling mixing and synergistic reaction device for biogas slurry hydrothermal fluid to solve the above-mentioned technical problems. Summary of the Invention

[0005] To address the problem that existing hydrothermal slurry cyclone mixing reactors mostly rely on hydrocyclones for mixing, resulting in incomplete mixing and inconvenience due to the liquid only rotating in a single stage, a multi-stage hydrothermal cyclone mixing and synergistic reaction device for biogas slurry is provided. A brief overview of this invention is given below to provide a basic understanding of certain aspects of the invention. It should be understood that this overview is not an exhaustive summary of the invention. It is not intended to identify key or essential parts of the invention, nor is it intended to limit the scope of the invention.

[0006] The technical solution of the present invention: A multi-stage hydrothermal slurry mixing and synergistic reaction device includes a reaction tank, a discharge port at the bottom of the reaction tank, a hydrocyclone at the bottom inside the reaction tank, a sealing cover at the top of the reaction tank, a feed inlet at the top of the sealing cover, and a reaction mechanism inside the reaction tank. The reaction mechanism includes a rotating rod disposed inside the reaction tank. One end of the rotating rod is rotatably connected to a sealing cover. A servo motor is disposed on the top of the sealing cover. The output end of the servo motor is connected to the rotating rod. Connecting blocks are connected to the upper and lower sides of the rotating rod. A stirring rod is connected to two sets of the connecting blocks. A stirring blade is disposed between the two sets of the connecting blocks.

[0007] Preferably, the feed inlet includes a biogas slurry feed inlet and a hydrothermal feed inlet, and a biogas slurry feed inlet is also provided on one side of the top of the sealing cover, and a hydrothermal feed inlet is also provided on the other side of the top of the sealing cover; To address the problem that existing hydrothermal slurry mixing reactors often rely on hydrocyclones for mixing, resulting in incomplete mixing and inconvenience due to the liquid only rotating in one direction, this new reaction mechanism includes a rotating rod located inside the reaction tank. One end of the rotating rod is rotatably connected to a sealing cover. A servo motor is mounted on the top of the sealing cover, and its output extends into the interior of the sealing cover and is fixedly connected to the rotating rod. Connecting blocks are fixedly connected to both the upper and lower ends of the rotating rod. Stirring rods are fixedly connected to the exterior of both sets of connecting blocks. Multiple sets of insertion slots are fixedly connected to opposite sides of both sets of connecting blocks. The container has an installation rod between the insertion slots. A stirring blade is fixedly connected to the side of the installation rod. The installation rod is placed between two sets of insertion slots and fixed in place by an electric actuator. This secures the installation rod to the reaction vessel, fixing the sealing cap to the container. A servo motor drives a rotating rod to rotate, which in turn rotates an externally mounted connecting block. The rotation of the externally mounted stirring rod and multiple sets of inclined, circularly arrayed stirring blades facilitates thorough agitation of the liquid inside the reaction vessel, ensuring complete reaction. The container is easy to install and disassemble, simple and quick to operate, and convenient to use.

[0008] Preferably, in order to solve the problem of convenient mixing of liquids, multiple sets of stirring blades are arranged at an angle and in a ring array. The stirring blades are provided with grooves to fully mix the liquid and make it convenient to use.

[0009] Preferably, the two sets of connecting blocks are connected to multiple sets of plug slot blocks on opposite sides, and an installation rod is provided between the upper and lower corresponding plug slot blocks. A stirring blade is fixedly connected to the side of the installation rod.

[0010] Preferably, in order to solve the problem of easy installation and disassembly of the stirring blade, electric push rods are provided at both ends of the mounting rod. The output end of the electric push rod is inserted into the insertion slot block. By inserting the electric push rod into the insertion slot block, the mounting rod can be easily fixed to the insertion slot block, which is convenient to use.

[0011] Preferably, to solve the problem of cleaning the inner wall of the reaction vessel, multiple sets of stirring rods are arranged in a circular array, and one end of two sets of stirring rods is fixedly connected to an installation slot block. The installation slot block is provided with an installation block inside, and a cleaning block is fixedly connected to one side of the installation block. When the stirring rods rotate, they will drive the installation slot block to rotate, thereby allowing the two sets of cleaning blocks to rotate inside the reaction vessel, thus cleaning the inner wall of the reaction vessel through the cleaning blocks. The operation is simple, quick, and convenient.

[0012] Preferably, in order to solve the problem of convenient installation and disassembly of the mounting block, the mounting block is inserted into the mounting groove block and the mounting block is fixed to the mounting groove block by bolts, which facilitates disassembly and makes it convenient to use.

[0013] Preferably, to address the issue of convenient cleaning of the reaction vessel, the two sets of cleaning blocks are symmetrically arranged, with the sides of the cleaning blocks fitting against the inner wall of the reaction vessel and the height of the cleaning blocks matching the height of the reaction vessel. The symmetrical arrangement of the cleaning blocks and their external fit against the inner wall of the reaction vessel facilitates cleaning of the inner wall of the reaction vessel and makes it convenient to use.

[0014] The present invention has the following beneficial effects: The reaction mechanism of this invention places the mounting rod between two sets of insertion slots. The mounting rod is then fixed between the insertion slots by an electric actuator, which in turn connects to the insertion slots. This fixes the sealing cap to the reaction vessel. A servo motor drives a rotating rod to rotate, which in turn rotates an externally mounted connecting block. The rotating rod, along with multiple sets of inclined, circularly arrayed stirring blades, facilitates thorough agitation of the liquid inside the reaction vessel, ensuring complete reaction. The mechanism is also easy to install and disassemble, simple and quick to operate, and convenient to use.

[0015] The reaction mechanism of this invention fixes the mounting block inside the mounting groove, so that the side of the cleaning block fits against the inside of the reaction tank. During the rotation of the stirring rod, the mounting groove will rotate, so that the two sets of cleaning blocks can rotate inside the reaction tank, thereby cleaning the inner wall of the reaction tank through the cleaning blocks. The operation is simple and quick, and it is convenient to use. Attached Figure Description
