Description

Technical Field

[0001] This utility model belongs to the field of experimental equipment technology, specifically relating to a high-efficiency mixing high-temperature reaction device. Background Technology

[0002] High-temperature homogeneous reaction is a core process in chemical, metallurgical, and new energy fields for material synthesis, catalyst preparation, and energy conversion. In existing technologies, such reactions typically employ a static heating method: the reaction vessel is sealed and placed directly inside a heating device such as a muffle furnace, where heating is achieved through thermal radiation and natural convection. However, this method has the following technical drawbacks:

[0003] 1. Uneven thermal field distribution

[0004] In static heating mode, a significant axial and radial temperature gradient is formed inside the reaction vessel:

[0005] • The concentrated heat radiation near the heating source caused the local temperature to exceed the threshold, with the highest temperature difference measured in the experiment reaching ±50℃.

[0006] • Cold zones are formed in the reactant accumulation area due to impaired heat conduction, leading to inconsistent reaction kinetics such as abnormal grain growth and deviations in the distribution of active components.

[0007] 2. Low mass transfer efficiency

[0008] When reactants are left to stand, mixing relies solely on natural diffusion or limited convection, which presents the following problems:

[0009] • Particle agglomeration and sedimentation: High-density or large-particle materials tend to accumulate at the bottom of the tank, resulting in a reduction of the effective contact area by more than 50%;

[0010] • Low energy efficiency: Energy waste in local overheated areas accounts for 30%-40% of the total system energy consumption, while cold areas require extended heating time to compensate. Utility Model Content

[0011] This invention provides a highly efficient high-temperature mixing reaction device to address the above-mentioned problems.

[0012] To achieve the above objectives, the present invention adopts the following technical solution:

[0013] A high-efficiency mixing high-temperature reaction device includes a muffle furnace, a movable door on one side of the muffle furnace, a fixed plate on the other side of the muffle furnace, a rotary motor mounted on the fixed plate, the output shaft of the rotary motor passing through the side wall of the muffle furnace and fixedly connected to the sun gear in a planetary gear mechanism, a fixed shaft fixedly connected to the planet gears in the planetary gear mechanism, and a clamping mechanism fixedly mounted at the other end of the fixed shaft, holding a reaction vessel in the clamping mechanism.

[0014] Furthermore, the planetary gear mechanism includes a gear ring, which is fixedly mounted on the inner wall of the muffle furnace. Multiple planetary gears are meshed inside the gear ring, and the multiple planetary gears mesh with a sun gear. A rotating disk is provided on the side of the gear ring away from the rotating motor. The rotating disk is rotatably connected to the gear ring. A fixed shaft passes through the rotating disk and is rotatably connected to the rotating disk.

[0015] Furthermore, a limiting groove is formed on the outer wall of the gear ring, and a limiting ring corresponding to the limiting groove is provided on the rotating disk. The rotational connection between the rotating disk and the gear ring is realized through the cooperation of the limiting groove and the limiting ring.

[0016] Furthermore, the clamping mechanism includes a fixed plate, on which multiple fixed rods are evenly arranged in a circular pattern. A reinforcing ring is connected to the other end of the multiple fixed rods. A locking nut is threaded onto the fixed rod, and the reaction vessel is fixed by the locking nut.

[0017] Furthermore, the reaction vessel includes a vessel body and a cover, which are sealed together. Multiple lifting plates are arranged evenly in a circular pattern inside the vessel body to facilitate the full heating and mixing of the reactants and prevent the reactants from sliding and accumulating at the bottom of the reaction vessel.

[0018] Furthermore, a speed regulator is also provided on the fixed plate, which is electrically connected to the rotating motor to facilitate the adjustment of the rotating motor's speed.

[0019] Compared with the prior art, the present invention has the following advantages:

[0020] This invention uses a planetary gear mechanism to drive the reaction vessel to revolve around the sun while simultaneously rotating on its own axis, ensuring uniform heating of the reactants and improving reaction efficiency. Furthermore, the application includes a lifting plate inside the reaction vessel, which further ensures sufficient and uniform heating of the reactants, preventing materials from sliding and accumulating at the bottom of the vessel, thus further improving reaction efficiency.

[0021] This invention supports simultaneous heating of multiple reaction vessels, which facilitates simultaneous experiments on different reactants and improves experimental efficiency. In addition, the reaction vessels in this invention are detachable, which allows for easy replacement with reaction vessels of suitable materials according to different reactants, thus expanding the application range of this invention.
