[0002] The manufacturing process of triethyl phosphate generates waste gas containing various harmful substances. If discharged directly without treatment, it will cause serious environmental pollution. Currently, although some manufacturing equipment has waste gas treatment capabilities, the treatment effect is poor, and the equipment often needs to be shut down for a long time during maintenance such as filter cleaning, which greatly affects production efficiency. Utility Model Content
[0003] In view of the problems existing in the current low-emission triethyl phosphate manufacturing equipment, this utility model is proposed.
[0004] Therefore, the purpose of this invention is to provide a low-emission triethyl phosphate manufacturing apparatus, which solves the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A low-emission triethyl phosphate manufacturing apparatus includes a base plate and a reaction vessel. The reaction vessel is fixedly disposed on one side of the upper surface of the base plate. An exhaust pipe is disposed on one side of the top of the reaction vessel. A filter shell is fixedly disposed on the upper surface of the base plate and on one side of the reaction vessel. One end of the exhaust pipe extends into the upper inner side of the filter shell. Both ends of the filter shell away from the reaction vessel have through slots, and filter modules are inserted into the two through slots. An exhaust pipe is disposed on one side of the lower end of the filter shell. A horizontal plate is fixedly disposed on the outer wall of the middle section of the filter shell away from the reaction vessel. A rotating rod is rotatably sleeved in the middle of the horizontal plate. A transmission mechanism for moving the two filter modules is disposed at the rear end of the rotating rod. A drive mechanism for rotating the rotating rod is disposed at the front side of the horizontal plate.
[0007] Preferably, the transmission mechanism includes a push rod and round pins. The push rod is fixedly sleeved on the rear end of the rotating rod, and the two round pins are rotatably disposed at the front ends of the push rod. Each of the two filter modules has a strip-shaped opening on its outer side, and the front end of the round pin passes through the corresponding strip-shaped opening.
[0008] Preferably, the driving mechanism includes a first bevel gear and a second bevel gear. A side plate is fixedly provided on the front side of the cross plate, and a driving rod is rotatably provided on the side plate near the rotating rod. The first bevel gear is fixedly sleeved on the end of the driving rod near the rotating rod, and the second bevel gear is fixedly sleeved on the front end of the rotating rod. The first bevel gear and the second bevel gear are meshed and connected. A motor is fixedly provided on the side plate away from the driving rod, and the output end of the motor is fixedly connected to one end of the driving rod.

[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows:
[0014] 1. This utility model introduces exhaust gas into the filter shell through the exhaust pipe. The filter plate filters out large particulate matter, and the primary and secondary adsorption plates adsorb tiny pollutants, which can effectively reduce environmental pollution.
[0015] 2. In this utility model, the motor drives the drive rod to rotate, which in turn causes the first bevel gear to drive the second bevel gear to rotate, thereby causing the rotating rod to rotate. The rotating rod drives the push rod to rotate, and the push rod drives the round pin to rotate around the rotating rod as an axis. During this process, the round pin slides in the slot, so that the round pin on one side pulls the corresponding filter module out of the filter shell, and the round pin on the other side pushes the corresponding filter module into the filter shell. This allows the filter modules on both sides to perform filtration work alternately, thereby reducing downtime caused by filter module maintenance. Attached Figure Description

Detailed Implementation
[0022] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0023] This utility model discloses a low-emission triethyl phosphate manufacturing apparatus.
[0024] Example 1
[0025] Reference Figure 1-3 A low-emission triethyl phosphate manufacturing device includes a base plate 1 and a reaction vessel 2. The reaction vessel 2 is fixedly installed on one side of the upper surface of the base plate 1. An exhaust pipe 4 is provided on one side of the top of the reaction vessel 2. A filter shell 3 is fixedly installed on the upper surface of the base plate 1 and on one side of the reaction vessel 2. One end of the exhaust pipe 4 extends to the upper inside of the filter shell 3. Both ends of the side of the filter shell 3 away from the reaction vessel 2 are provided with through slots. Filter modules 5 are inserted into the inside of the two through slots. A mounting hole is provided in the middle of the filter module 5. A filter plate 9, a primary adsorption plate 10 and a secondary adsorption plate 11 are installed in the mounting hole from top to bottom, which can fully filter the exhaust gas. An exhaust pipe 8 is provided on one side of the lower end of the filter shell 3. A horizontal plate is fixedly installed on the outer wall of the middle end of the side of the filter shell 3 away from the reaction vessel 2. A rotating rod 12 is rotatably sleeved in the middle of the horizontal plate. A transmission mechanism for moving the two filter modules 5 is provided at the rear end of the rotating rod 12. A drive mechanism for rotating the rotating rod 12 is provided on the front side of the horizontal plate.
[0026] Example 2
[0027] Reference Figure 1-3 The transmission mechanism includes a push rod 6 and a round pin 7. The push rod 6 is fixedly sleeved at the rear end of the rotating rod 12. The two round pins 7 are rotatably set at the front ends of the push rod 6. A strip-shaped opening is opened at one end of the outer side of each of the two filter modules 5. The front end of the round pin 7 passes through the corresponding strip-shaped opening. An anti-detachment ring is fixedly sleeved on the front end of the round pin 7 to prevent the round pin 7 from slipping out of the strip-shaped opening as much as possible.
[0028] Implementation Three
[0029] Reference Figure 1-3The drive mechanism includes a first bevel gear 15 and a second bevel gear 16. A side plate 13 is fixedly installed on the front side of the cross plate. A drive rod 14 is rotatably installed on the side plate 13 near the rotating rod 12. The first bevel gear 15 is fixedly sleeved on the end of the drive rod 14 near the rotating rod 12. The second bevel gear 16 is fixedly sleeved on the front end of the rotating rod 12. The first bevel gear 15 and the second bevel gear 16 are meshed and connected. A motor 17 is fixedly installed on the side plate 13 away from the drive rod 14. The output end of the motor 17 is fixedly connected to one end of the drive rod 14.
[0030] Example 4
[0031] Reference Figure 1-3 A first sealing plate 18 is fixedly sleeved on one side of the filter module 5. One side of the first sealing plate 18 abuts against the outer wall of the through groove, which can block the outer wall of the through groove when the filter part of the filter module 5 is pushed into the filter shell 3. A second sealing plate 19 is fixedly sleeved on one side of the filter module 5. One side of the second sealing plate 19 abuts against the inner wall of the filter shell 3, which can block the through groove when the filter part of the filter module 5 is pulled out of the filter shell 3.
[0032] In this invention, during use, the waste gas generated during the synthesis of triethyl phosphate in the reactor 2 enters the interior of the filter shell 3 through the exhaust pipe 4. At this time, a filter module 5 is in working state inside the filter shell 3. The waste gas passes through the filter plate 9 (filtering large particulate impurities), the primary adsorption plate 10 (adsorbing volatile organic compounds such as ethanol vapor), and the secondary adsorption plate 11 (adsorbing acidic gases such as hydrogen chloride) in the filter module 5 in sequence. The purified gas is discharged from the exhaust pipe 8, achieving low emissions.
[0033] When the working filter module 5 needs cleaning and maintenance, start the motor 17. The motor 17 drives the drive rod 14 to rotate. The drive rod 14 is driven by the meshing of the first bevel gear 15 and the second bevel gear 16, which drives the rotating rod 12 and the push rod 6 at the rear end to rotate synchronously. The round pins 7 at both ends of the push rod 6 move in a circle with the push rod 6, slide in the strip-shaped opening of the filter module 5 and drive the two filter modules 5 to move in opposite directions along the through groove: the original working filter module 5 is pulled out of the filter shell 3, and at the same time, another spare filter module 5 is pushed into the inside of the filter shell 3 to take over the filtration of exhaust gas.
[0034] During the switching process, the first sealing plate 18 on the outside of the original filter module 5 moves with it and abuts against the outer wall of the channel, while the second sealing plate 19 on the inside of the newly pushed filter module 5 abuts against the inner wall of the filter shell 3, ensuring that the filter shell 3 is always in a sealed state to prevent exhaust gas leakage. The filter module 5 to be replaced can be cleaned offline or the filter material can be replaced. After cleaning, it is used as a spare module to wait for the next switching.
[0035] The anti-detachment ring prevents the round pin 7 from slipping off the strip opening, ensuring stable transmission; the combination design of the two-stage adsorption plate and filter plate improves the exhaust gas purification effect and is suitable for the treatment of complex exhaust gas in the production of triethyl phosphate. This device greatly reduces the equipment downtime caused by maintenance through the rapid switching of dual filter modules, taking into account both environmental protection requirements and production efficiency.
[0036] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
