Description

Technical Field

[0001] This utility model relates to the field of chemical equipment technology, specifically to a phosphorus pentachloride feeding reaction device. Background Technology

[0002] Phosphorus pentachloride is an important chemical raw material with wide applications in the synthesis of organophosphorus pesticides, fire retardant materials, pharmaceutical intermediates, and as a catalyst and regulator of polymerization reactions. For example, phosphorus pentachloride needs to be added to the reaction equipment when producing lithium hexafluorophosphate.

[0003] A search revealed a utility model patent with Chinese patent publication number CN221638061U, which discloses a phosphorus pentachloride feeding reaction device, belonging to the field of chemical production. The device includes a mixing reaction section, which comprises a feeding section and a discharging section. The feeding section is connected to a phosphorus pentachloride inlet and a reaction liquid inlet. The mixing reaction section also includes a negative pressure channel.

[0004] The aforementioned device uses a negative pressure channel to force phosphorus pentachloride into the mixing and reaction section to prevent the generated gas from reacting with phosphorus pentachloride at the phosphorus pentachloride inlet and causing caking. However, the principle of the negative pressure feeding equipment is to first evacuate the chamber connected to the feed port, and then open the vacuum chamber to extract the material using negative pressure. Since the feed port is connected to the equipment, some harmful gases will be mixed in. When evacuating, these gases will flow into the outside, posing a safety hazard. Summary of the Invention

[0005] The purpose of this invention is to provide a phosphorus pentachloride feeding reaction 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 phosphorus pentachloride feeding reaction device, comprising a reaction vessel, a feeding assembly installed on the top of the reaction vessel, the feeding assembly including a mounting cover fixedly connected to the outer wall of the top of the reaction vessel, the mounting cover communicating with the internal space of the reaction vessel, two connecting holes opened in the middle of the mounting cover, the same feeding ring being rotatably connected to the two connecting holes through bearings, the outer circumference of the feeding ring fitting against the inner circumference of the mounting cover, a vertically arranged storage cavity opened in the middle of the feeding ring, a piston being slidably inserted into the storage cavity, two limiting strips being provided on both sides of the inner wall of the storage cavity, and one bottom end of the piston being slidably inserted into the gap between two of the limiting strips.

[0007] As a further preferred embodiment of this technical solution, a mounting plate is fixedly connected to one side of the outer wall of the mounting cover, and a worm gear is rotatably connected inside the mounting plate via a bearing. A worm wheel is coaxially fixed to one end of the rotating shaft of the feeding ring, and the worm gear meshes with the worm wheel. A motor is fixedly mounted on one side of the outer wall of the mounting plate, and the output end of the motor is coaxially fixed to one end of the worm gear.

[0008] To ensure the smooth introduction of phosphorus pentachloride into the reactor while preventing the toxic gases produced by the reaction from entering the storage chamber, thus improving the safety of the device, the piston is positioned at the bottom of the storage chamber under gravity, forming a chamber capable of holding materials. The required phosphorus pentachloride is added to the storage chamber, and the motor on the outside of the mounting cover is started. The motor drives the worm gear to rotate, which in turn drives the worm wheel to rotate. The worm wheel then drives the feeding ring to rotate synchronously. Subsequently, the opening of the feeding ring flips and fits against the inner wall of the mounting cover. Then, the opening of the piston, originally at the top, connects to the inside of the reactor, allowing the phosphorus pentachloride to slide into the reactor. Meanwhile, the opening at the bottom connects to the outside, and the piston, now at the top, slides downwards under gravity. The toxic gases mixed into the storage chamber are pushed back into the reactor by the piston, effectively preventing the toxic gases from escaping to the outside.

[0009] As a further preferred embodiment of this technical solution, a mixing assembly is installed inside the reactor. The mixing assembly includes an auger rotatably connected to the inner wall of the bottom of the reactor, and an electric motor is fixedly installed on the outer wall of the bottom of the reactor, with the output end of the electric motor coaxially fixed with one end of the auger.

[0010] As a further preferred embodiment of this technical solution, a support plate is coaxially fixed to the outer wall of the top of the auger, and several vertically arranged extension rods are fixedly connected to both sides of the bottom outer wall of the support plate.

[0011] The electric motor at the bottom of the reactor is started, which drives the auger to rotate. The raw materials at the bottom are pushed upward, allowing the various raw materials to mix more quickly, which helps to speed up the reaction. The auger drives several extension rods to revolve around the auger through the support plate, which can agitate the raw materials again and further improve the reaction speed.

[0012] As a further preferred embodiment of this technical solution, a vertically arranged guide hopper is fixedly connected to the outer circumference of the mounting cover, and the opening at the bottom of the guide hopper is positioned directly opposite one end of the storage cavity.

[0013] As a further preferred embodiment of this technical solution, a rubber layer is bonded inside the mounting cover, and the rubber layer wraps the feeding ring inside. Two annular grooves are opened on the outside of the piston, and a rubber ring is fitted inside each of the two annular grooves.

[0014] As a further preferred embodiment of this technical solution, the inner circumferential wall of the reactor is provided with an exhaust pipe, and the exhaust pipe is connected to an external purification device.

[0015] This utility model provides a phosphorus pentachloride feeding and reaction device, which has the following beneficial effects:

[0016] (1) By setting up a feeding component, this utility model ensures that phosphorus pentachloride can be smoothly fed into the reactor while the toxic gas produced by the reaction will not mix into the storage chamber, which is conducive to improving the safety of the device. The piston is at the bottom of the storage chamber under the action of gravity, thus forming a chamber that can hold materials. The required phosphorus pentachloride is fed into the storage chamber, and the motor on the outside of the mounting cover is started. The motor drives the worm to rotate. The worm drives the worm wheel to rotate through meshing. The worm wheel drives the feeding ring to rotate synchronously. Then the opening of the feeding ring flips and fits against the inner wall of the mounting cover. Then the opening of the piston, which was originally at the top, is connected to the inside of the reactor. The phosphorus pentachloride will slide into the reactor. The opening, which was originally at the bottom, is connected to the outside. The piston, which has changed to the top position, slides down under the action of gravity. The toxic gas mixed into the storage chamber will be pushed back into the reactor by the piston, effectively preventing the toxic gas from escaping to the outside.

[0017] (2) By setting up a mixing component, the electric motor at the bottom of the reactor is started. The electric motor drives the auger to rotate, and the raw materials at the bottom are pushed upward, so that the various raw materials can be mixed faster, which is conducive to speeding up the reaction. The auger drives several extension rods to revolve around the auger through the support plate, which can stir the raw materials again and further improve the reaction speed.

Detailed Implementation

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0025] This utility model provides a technical solution as follows: Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown in this embodiment, a phosphorus pentachloride feeding reaction device includes a reactor 1. A feeding component 3 is installed on the top of the reactor 1. The feeding component 3 includes a mounting cover 301 fixedly connected to the outer wall of the top of the reactor 1. The mounting cover 301 is connected to the internal space of the reactor 1. Two connecting holes 302 are opened in the middle of the mounting cover 301. The same feeding ring 303 is rotatably connected to the two connecting holes 302 through bearings. The outer circumference of the feeding ring 303 fits against the inner circumference of the mounting cover 301. A vertically arranged storage cavity 304 is opened in the middle of the feeding ring 303. A piston 306 is slidably inserted into the storage cavity 304. Two limiting strips 305 are provided on both sides of the inner wall of the storage cavity 304. One end of the bottom of the piston 306 is slidably inserted into the gap between the two limiting strips 305.

[0026] A mounting plate 308 is fixedly connected to one side of the outer wall of the mounting cover 301. A worm gear 309 is rotatably connected inside the mounting plate 308 via a bearing. A worm wheel 307 is coaxially fixed to one end of the rotating shaft of the feeding ring 303. The worm gear 309 meshes with the worm wheel 307. A motor 310 is fixedly mounted on one side of the outer wall of the mounting plate 308. The output end of the motor 310 is coaxially fixed to one end of the worm gear 309.

[0027] Piston 306, under the influence of gravity, is positioned at the bottom of storage chamber 304, thus forming a chamber capable of holding materials. The required phosphorus pentachloride is added into storage chamber 304. Motor 310, located outside mounting cover 301, is activated, driving worm gear 309 to rotate. Worm gear 309, through meshing, drives worm wheel 307 to rotate, which in turn drives feeding ring 303 to rotate synchronously. The opening of feeding ring 303 then flips and fits against the inner wall of mounting cover 301. Next, the opening of piston 306, originally at the top, connects to the inside of reactor 1, allowing phosphorus pentachloride to slide into reactor 1. Meanwhile, the opening at the bottom connects to the outside. Piston 306, now at the top, slides downwards under gravity, pushing the toxic gas mixed in with storage chamber 304 back into reactor 1, effectively preventing the toxic gas from escaping to the outside.

[0028] like Figure 2 As shown, a mixing component 4 is installed inside the reactor 1. The mixing component 4 includes an auger 401 rotatably connected to the inner wall of the bottom of the reactor 1. An electric motor is fixedly installed on the outer wall of the bottom of the reactor 1, and the output end of the electric motor is coaxially fixed with one end of the auger 401.

[0029] A support plate 402 is coaxially fixed to the top outer wall of the auger 401, and several vertically arranged extension rods 403 are fixedly connected to both sides of the bottom outer wall of the support plate 402.

[0030] The electric motor at the bottom of the reactor 1 is started, which drives the auger 401 to rotate. The raw materials at the bottom are pushed upward, which allows the various raw materials to mix more quickly and helps to speed up the reaction. The auger 401 drives several extension rods 403 to revolve around the auger 401 through the support plate 402, which can stir the raw materials again and further improve the reaction speed.

[0031] like Figure 1 As shown, a vertically arranged guide hopper 2 is fixedly connected to the outer circumference of the mounting cover 301. The opening at the bottom of the guide hopper 2 is set directly opposite one end of the storage cavity 304, making the feeding process convenient enough.

[0032] like Figure 3 and Figure 4 As shown, a rubber layer 311 is bonded inside the mounting cover 301, and the rubber layer 311 wraps the feeding ring 303 inside, which can increase the sealing between the feeding ring 303 and the mounting cover 301. Two annular grooves are opened on the outside of the piston 306, and a rubber ring 312 is fitted inside each of the two annular grooves, which can increase the sealing between the piston 306 and the storage cavity 304.

[0033] like Figure 1As shown, the inner circumference of the reactor 1 is provided with a gas outlet pipe, which is connected to an external purification device for discharging and treating the gas generated during the reaction process.

[0034] This utility model provides a phosphorus pentachloride feeding and reaction device, the specific working principle of which is as follows:

[0035] When the device is in operation, piston 306 is positioned at the bottom of storage chamber 304 under gravity, thus forming a chamber capable of holding materials. The required phosphorus pentachloride is added into storage chamber 304. Motor 310, located outside mounting cover 301, is then activated. Motor 310 drives worm gear 309 to rotate, which in turn drives worm wheel 307 to rotate. Worm wheel 307 then drives feeding ring 303 to rotate synchronously. Subsequently, the opening of feeding ring 303 flips and comes into contact with the inner wall of mounting cover 301. Then, the opening of piston 306, originally at the top, connects to the inside of reactor 1, allowing phosphorus pentachloride to slide into reactor 1. The opening at the bottom connects to the outside. Piston 306, now at the top position, slides downwards under gravity. The toxic gas mixed in with the storage chamber 304 is pushed back into reactor 1 by piston 306, effectively preventing the toxic gas from escaping to the outside. Then, liquid materials are poured into reactor 1 to start the reaction. At the same time, the electric motor at the bottom of reactor 1 is started, driving the auger 401 to rotate. The raw materials at the bottom are pushed upwards, allowing the various raw materials to mix more quickly, which helps to accelerate the reaction speed. The auger 401 drives several extension rods 403 to revolve around the auger 401 through the support plate 402, which can agitate the raw materials again, further improving the reaction speed.
