Description

Technical Field

[0001] This utility model belongs to the field of chemical production technology, specifically relating to a pulse vibration discharge reactor for phosphorus pentachloride. Background Technology

[0002] In the laboratory preparation of phosphorus pentachloride, the main function of the reactor is to provide reaction space, allowing chlorine gas to fully contact with phosphorus trichloride and undergo a chlorination reaction. This mainly includes mixing reactants, controlling reaction conditions, and separating products.

[0003] In traditional stirred tank reactors, phosphorus pentachloride crystals tend to adhere to the inner wall of the reactor, forming a buildup layer. This not only reduces the effective reaction volume but also leads to blockage of the discharge port. To avoid this, existing technologies generally rely on periodic manual cleaning, which increases downtime and reduces production efficiency. Furthermore, while the scraper structure can alleviate the problem, it is difficult to prevent adhesion in dead zones.

[0004] Meanwhile, phosphorus pentachloride is solid at low temperatures and has poor fluidity. When discharging from a batch reactor, the solid material is prone to bridging at the outlet, requiring repeated mechanical clearing. In continuous processes, the discharge rotary valve of the solid-liquid separator is prone to malfunction due to particle jamming.

[0005] Therefore, in order to address the above-mentioned technical problems, it is necessary to provide a pulse vibration discharge reactor for phosphorus pentachloride. Utility Model Content

[0006] The purpose of this invention is to provide a pulse vibration discharge reactor for phosphorus pentachloride, which can solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the technical solution provided by a specific embodiment of this utility model is as follows:

[0008] A pulse vibration discharge reactor for phosphorus pentachloride includes:

[0009] The reaction vessel includes a feed inlet, a discharge outlet, and an air inlet. An anti-clogging mechanism is installed on the outside of the reaction vessel, and a cleaning mechanism is installed inside the reaction vessel. The cleaning mechanism includes a ventilation ring, and several air outlet pipes for blowing away phosphorus pentachloride are installed on the outside of the ventilation ring. A first telescopic pipe is installed at one end of the ventilation ring, and the end of the first telescopic pipe away from the ventilation ring is installed at one end of the air inlet. The first telescopic pipe is connected to the air inlet. A driving mechanism for driving the ventilation ring is installed inside the reaction vessel.

[0010] In one or more embodiments of this utility model, the driving mechanism includes a reciprocating lead screw, which is installed inside the reactor.

[0011] In one or more embodiments of this utility model, the included angle between the air outlet duct and the tangent of the ventilation ring is 30° to 45°.

[0012] In one or more embodiments of this utility model, a second telescopic tube matching the reciprocating lead screw is installed at the bottom of the moving ring.

[0013] In one or more embodiments of this utility model, an electric heating wire is installed outside the air inlet, and a temperature measuring meter matching the electric heating wire is installed on the ventilation ring.

[0014] In one or more embodiments of this utility model, the gas introduced into the reaction vessel through the gas inlet is one or more combinations of argon, helium, neon, and nitrogen.

Detailed Implementation

[0027] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0028] like Figures 1-3As shown, a pulse vibration discharge reactor for phosphorus pentachloride in one embodiment of this utility model includes a reaction vessel 1. The reaction vessel 1 generally includes a vessel body structure, a heating and temperature control system, and a gas management and mixing system. The produced phosphorus pentachloride is automatically quantitatively packaged, sealed, and stored. The vessel body structure is equipped with an inlet 101, an outlet 102, and an air inlet 103. A cleaning mechanism is installed inside the reaction vessel 1 to peel off phosphorus pentachloride adhering to the inner wall of the reaction vessel 1, minimizing adhesion in dead zones. The peeled phosphorus pentachloride is discharged through the air inlet 103. An anti-clogging mechanism matching the cleaning assembly is installed outside the reaction vessel 1. The anti-clogging mechanism can minimize the jamming of phosphorus pentachloride at the outlet 102 during discharge.

[0029] like Figure 2 As shown, the cleaning mechanism includes a ventilation ring 201. Several outlet pipes 202 for blowing off phosphorus pentachloride are installed on the outside of the ventilation ring 201. A first telescopic pipe 203 is installed at one end of the ventilation ring 201. The end of the first telescopic pipe 203 away from the ventilation ring 201 is installed at one end of the air inlet 103 and is connected to the air inlet 103. A drive mechanism for driving the ventilation ring 201 is installed inside the reactor 1. The gas introduced into the reactor 1 through the air inlet 103 is one or a combination of argon, helium, neon, and nitrogen. The gas enters the first telescopic pipe 203 from the air inlet 103, then enters the ventilation ring 201, and is subsequently blown towards the inner wall of the reactor 1 from the outlet pipes 202. Under the action of the drive mechanism, it moves and blows off the phosphorus pentachloride adhering to the inner wall of the reactor 1.

[0030] like Figure 3 As shown, the drive mechanism includes a reciprocating screw 204, which is installed inside the reactor 1. A movable ring 205 is installed in the middle of the ventilation ring 201. A ball bearing 206 matching the reciprocating screw 204 is installed inside the movable ring 205. A ball groove 2051 matching the ball bearing 206 is formed inside the movable ring 205. A rotating connector 207 matching the reciprocating screw 204 is installed between the movable ring 205 and the first telescopic pipe 203. The angle between the outlet pipe 202 and the tangent of the ventilation ring 201 is 30° to 45°. As the gas is blown out from the outlet pipe 202, due to the inclined setting of the outlet pipe 202, the gas provides a reaction force to the ventilation ring 201 and the outlet pipe 202 under the action of the inner wall of the reactor 1. This causes the outlet pipe 202 to drive the ventilation ring 201 to rotate, and the moving ring 205 rotates accordingly. During the rotation, the ball bearing 206 slides along the reciprocating screw 204, realizing the up and down movement of the outlet pipe 202. This strips phosphorus pentachloride from various parts of the reactor 1.

[0031] like Figure 3As shown, a second telescopic tube 208 matching the reciprocating screw 204 is rotatably mounted on the bottom of the moving ring 205 via a rotating connecting ring. The second telescopic tube 208 can protect the outer wall of the reciprocating screw 204, and prevent phosphorus pentachloride from adhering to the outer wall of the reciprocating screw 204 as much as possible, thus affecting the up and down movement of the moving ring 205.

[0032] like Figure 4 As shown, an electric heating wire 1031 is installed outside the air inlet 103, and a temperature measuring gauge 1032 matching the electric heating wire 1031 is installed on the ventilation ring 201. The electric heating wire 1031 heats the gas to ensure that the gas in contact with phosphorus pentachloride is kept as cool as possible, which would cause phosphorus pentachloride to adhere tightly and affect the yield.

[0033] like Figures 3-4 As shown, the anti-clogging mechanism includes a motor 301, which is installed on the outside of the reactor 1 near the discharge port 102. An eccentric wheel 302 is installed at the output end of the motor 301. The vibration generated during the rotation of the eccentric wheel 302 driven by the motor 301 dislodges the phosphorus pentachloride near the discharge port 102.

[0034] like Figure 4 As shown, a PWM controller matched with motor 301 is installed on reactor 1. The PWM controller is used to control the speed of motor 301, thereby stripping phosphorus pentachloride as much as possible.

[0035] like Figures 3-4 As shown, the parameters of motor 301 are: frequency 15–25 Hz, amplitude 2–5 mm, and pulse duration to interval ratio of 1:2. This aims to avoid excessive amplitude that could damage the material structure, while ensuring sufficient time for the material to flow.

[0036] like Figures 1-4 As shown, reactor 1 has a stainless steel shell, and the exterior of reactor 1 is coated with Teflon. The highly corrosive inner stainless steel provides structural strength, while the outer Teflon coating provides chemical inert protection.

[0037] The model number Y180M-4 can be selected, and users can also choose different models according to actual market needs. Motor 301 is electrically connected to an external power supply, and since motor 301 is common knowledge to those skilled in the art, its specific structure, switching method, and working principle will not be described in detail here.

[0038] During operation, when it is necessary to clean the phosphorus pentachloride adhering to the inner wall of reactor 1, gas is introduced into the air inlet 103. As the gas is blown out from the air outlet 202, it rotates. With the cooperation of the reciprocating screw 204, the air outlet 202 rotates and moves up and down along the reciprocating screw 204, peeling off the phosphorus pentachloride adhering to the inner wall of reactor 1. The motor 301 is started, and the vibration generated by the motor 301 and the eccentric wheel 302 shakes out the solids accumulated at the discharge port 102.

[0039] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0040] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
