Description

Technical Field

[0001] This utility model relates to the field of chemical equipment technology, and in particular to an electrolyte cooling reaction vessel. Background Technology

[0002] During electrolyte production, a large amount of heat is generated inside the reactor, requiring timely cooling to maintain a suitable reaction temperature. Traditional cooling methods typically employ jacketed cooling or internal coil cooling, but these methods suffer from low cooling efficiency. Furthermore, the stirring devices in conventional reactors often only achieve stirring in one direction, making it difficult to thoroughly mix the electrolyte, leading to localized overheating and affecting product quality. Therefore, an electrolyte-cooled reactor is needed to meet these requirements. Utility Model Content

[0003] The purpose of this invention is to provide an electrolyte-cooled reaction vessel to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an electrolyte cooling reactor, comprising a reactor body, a spirally arranged cooling circulation pipeline on the outer wall of the reactor body, a frame on the top of the reactor body, a motor on the top of the frame, a first helical gear on the output end of the motor, a second helical gear meshing on one side of the first helical gear, a third helical gear meshing below the second helical gear, the meshing surfaces of the third helical gear and the first helical gear being symmetrical to each other, a negative pressure pump is provided inside the reactor body, the negative pressure pump consists of a shell and a pump wheel, the shell is connected to the third helical gear through a short pipe, the pump wheel is connected to the first helical gear through a rotating shaft, a pipe is connected to the bottom suction end of the shell, a stirring blade is provided on the outer wall of the pipe, and the discharge end of the side wall of the shell is connected to the inside of the reactor body.

[0005] Preferably, the vessel body is provided with a heat insulation layer, which wraps around the spiral cooling circulation pipeline. The heat insulation layer can effectively reduce heat loss, improve cooling efficiency, and prevent the external ambient temperature from affecting the reaction process.

[0006] Preferably, the frame is U-shaped, with the open end connected to the vessel body and both sides open. The first helical gear, the second helical gear, and the third helical gear are all arranged inside the frame, which facilitates daily lubrication and maintenance of the internal helical gears. The openings on both sides are conducive to heat dissipation and extend the service life of the equipment.

[0007] Preferably, the second helical gear is rotatably connected to a positioning shaft fixedly connected to one side of the inner wall of the frame, which ensures the stable operation of the second helical gear and improves the reliability of the transmission system.

[0008] Preferably, the first helical gear and the third helical gear are arranged coaxially, which simplifies the transmission structure, reduces energy loss, and improves transmission efficiency.

[0009] Preferably, the pump impeller consists of a circular wheel plate, several arc-shaped blades, and a circular ring. The circular ring is arranged at the suction end near the outer casing, and the discharge end of the outer casing is tangent to the rotation direction of the pump impeller. This pump impeller structure can generate strong negative pressure, effectively improving the liquid circulation efficiency, and the tangential design reduces flow resistance.

[0010] Preferably, the stirring blades are in four groups, evenly arranged in a circular shape, with each stirring blade distributed in a spiral shape from top to bottom. The spirally distributed stirring blades can form a three-dimensional stirring effect, achieving full mixing of materials and avoiding dead zones in the mixing.

[0011] The beneficial effects of this utility model are: In this invention, the heat exchange area is increased by the spiral-arranged cooling circulation pipeline, and with the addition of the insulation layer, uniform and efficient heat exchange is achieved, thereby improving cooling efficiency.

[0012] In this invention, the coordinated operation of the negative pressure pump and the stirring blades achieves both forced circulation of materials and multi-directional stirring, ensuring the uniformity of the reaction system. Furthermore, the helical gear set enables a single motor to drive multiple working components, resulting in a compact structure, high transmission efficiency, easier equipment maintenance, and reduced operating costs.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Reference Figure 1-4 An electrolyte-cooled reaction vessel mainly comprises four parts: vessel body 1, cooling system, transmission system, and stirring system.

[0017] Reference Figure 1-2 The vessel body 1 is made of corrosion-resistant material, and its outer wall is tightly wound with spirally arranged cooling circulation pipes 2. This spiral arrangement ensures full contact between the cooling medium and the wall of the vessel body 1, improving heat exchange efficiency. The cooling circulation pipes 2 are wrapped with a heat insulation layer 13, which is made of high-performance heat insulation material, preventing heat loss and avoiding the influence of external ambient temperature on the reaction process.

[0018] Reference Figure 3 The transmission system is mounted on a frame 3 at the top of the vessel body 1. The frame 3 has a U-shaped structure, with its open end fixed to the vessel body 1 and openings on both sides for easy heat dissipation and routine maintenance and lubrication. The motor 4 is mounted at the top of the frame 3, and its output shaft is connected to a first helical gear 5. The first helical gear 5 meshes with a second helical gear 6, which is rotatably connected to the inner wall of the frame 3 via a positioning shaft. Below the second helical gear 6, a third helical gear 7 meshes. The meshing surfaces of the third helical gear 7 and the first helical gear 5 are symmetrical and coaxially arranged. This gear arrangement forms a stable transmission system that effectively transmits the power of the motor 4 to all working components.

[0019] Reference Figure 3-4 The core of the mixing system is the negative pressure pump 8, which consists of a housing 9 and a pump impeller 10. The housing 9 is connected to the third helical gear 7 via a short pipe, and the pump impeller 10 is connected to the first helical gear 5 via a rotating shaft. The pump impeller 10 includes a circular wheel plate, arc-shaped blades, and a circular ring, with the circular ring arranged near the suction end of the housing 9. The discharge end of the housing 9 is tangent to the rotation direction of the pump impeller 10; this design reduces fluid resistance and improves pumping efficiency.

[0020] Reference Figure 3 A tube 11 is connected to the bottom suction end of the outer shell 9. Four sets of stirring blades 12 are arranged on the outer wall of the tube 11. These stirring blades 12 are evenly arranged in a circumferential shape, and each stirring blade 12 is distributed in a spiral shape from top to bottom. This arrangement forms a three-dimensional stirring mode, which can mix the electrolyte in the reactor in all directions.

[0021] Working process: After starting motor 4, the first helical gear 5 drives the second helical gear 6 and the third helical gear 7 to rotate simultaneously. The first helical gear 5 directly drives the pump wheel 10 to rotate in the forward direction, while the third helical gear 7 directly drives the outer casing 9 to rotate in the reverse direction. This creates a negative pressure in the negative pressure pump 8, drawing the electrolyte from the bottom of the vessel 1 through the pipe 11 and then discharging it from the discharge end on the side wall of the outer casing 9, forming a forced bottom-up circulating mixing effect. Simultaneously, the third helical gear 7 drives the outer casing 9 and the pipe 11 to rotate in the reverse direction, causing the stirring blade 12 to rotate inside the vessel, thus agitating the electrolyte. The spiral stirring blade 12 generates a composite axial and radial flow during rotation, which, combined with the circulating flow formed by the negative pressure pump 8, achieves efficient mixing of the electrolyte. During the cooling process, the cooling medium flows in the spiral cooling circulation pipe 2, exchanging heat with the electrolyte through the wall of the vessel 1. The insulation layer 13 ensures that the heat exchange during the cooling process is mainly concentrated inside the vessel body 1, which improves the cooling efficiency. Through the innovative transmission structure and stirring system, it realizes multiple functions driven by a single power source, which not only improves energy utilization efficiency, but also ensures the uniformity and temperature stability of the reaction system. It is particularly suitable for electrolyte production processes with strict temperature control requirements.

[0022] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
