Description

Technical Field

[0001] This utility model relates to the field of chlorobenzene production technology, specifically to a quantitative addition device for the production of chlorobenzene using AABI closed-loop technology. Background Technology

[0002] As a basic chemical raw material, the production and application of chlorobenzene require a balance between efficiency, safety, and environmental protection. With the development of intelligent control technology and green chemical processes, the chlorobenzene industry chain is upgrading towards high efficiency and low pollution.

[0003] During the production of chlorobenzene for AABI closed-loop processing, materials need to be added to the processing equipment through an additive device. However, the additive device does not have a quantitative feeding function and relies on manual or mechanical valve control, which leads to deviations in the amount added. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a quantitative addition device for the production of chlorobenzene for AABI closed-loop production, which has the advantages of quantitative addition and solves the problem that the addition device does not have quantitative addition capabilities.

[0005] This utility model discloses a quantitative addition device for the production of chlorobenzene using a closed-loop AABI process. The device includes a feeding box with a viewing window on its front. The feeding box has graduation lines on its front, located to the left of the viewing window. An inlet is located on the right side of the top of the feeding box, and an outlet is located at the bottom. A quantitative addition assembly is located within the inner cavity of the feeding box. This assembly includes a drive motor located at the top of the feeding box. A gear is located at the output end of the drive motor. A slide rod is located on one side of the gear. The surface of the slide rod has grooves that match the gear. A sliding sleeve is movably connected to the surface of the slide rod, and the surface of the sliding sleeve is fixedly connected to the top of the inner cavity of the feeding box. A piston is located at the bottom of the slide rod. A discharge port is located on the right side of the piston's inner cavity. A telescopic tube is connected to the top of the discharge port, and the top of the telescopic tube is fixedly connected to the inlet. This utility model allows for precise addition of materials when needed. When feeding material into the processing equipment, the drive motor first runs, driving the gears to rotate. The gears, in conjunction with the tooth grooves, move the sliding rod downwards. The sliding sleeve, in conjunction with the sliding rod, stabilizes the movement. The sliding rod then moves the piston downwards. The position of the piston can be observed through the viewing window, and the scale on one side of the viewing window indicates the amount of material that can be added to the feeding box. During the piston's movement, the telescopic tube on the piston extends and retracts. Once the piston reaches the required scale position, the drive motor stops. At this point, the material is transferred through the inlet to the telescopic tube, then through the telescopic tube to the discharge outlet, and finally through the discharge outlet to the bottom of the feeding box. After the material in the feeding box has been quantitatively added, it is transferred to the processing equipment through the outlet. This avoids the situation where the feeding equipment lacks quantitative feeding capabilities and relies on manual or mechanical valve control, which can lead to deviations in the amount of material added.

[0006] The present invention relates to a quantitative addition device for the production of chlorobenzene using a closed-loop AABI system. The bottom of the drive motor is engaged with a limiting plate, and the bottom of the limiting plate is fixedly connected to the feeding box. The limiting plate can fix the drive motor, thus improving its performance during use and preventing the drive motor from shaking and becoming unstable.

[0007] The present invention relates to a quantitative addition device for the production of chlorobenzene using a closed-loop AABI system. The top of the slide rod is fixedly connected to a limiting block, and the diameter of the limiting block is larger than the diameter of the slide rod. The limiting block can limit the movement of the slide rod when it moves downward, thus preventing the slide rod from falling out of the sleeve.

[0008] The present invention relates to a quantitative addition device for the production of chlorobenzene using a closed-loop AABI system. The bottom of the slide rod is fixedly connected to the piston via a connecting block, and the bottom of the slide rod is located at the center of the top of the piston. The connecting block can fix the connection between the bottom of the slide rod and the piston, preventing the piston from falling off the slide rod during use.

[0009] The present invention relates to a quantitative addition device for the production of chlorobenzene using AABI closed-loop technology, wherein a mounting plate is fixedly connected to the bottom of the surface of the feeding box, and the inner cavity of the mounting plate is provided with mounting holes.

[0010] The present invention relates to a quantitative addition device for the production of chlorobenzene using a closed-loop AABI process. The device includes a solenoid valve installed in the inner cavity of the discharge port, and the input end of the solenoid valve is electrically connected to an external controller. When leakage from the discharge port is required, the device can be controlled by the solenoid valve, making leakage from the discharge port more convenient.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. When material needs to be added to the processing equipment, this utility model first drives the motor to run, which in turn drives the gear to rotate. The gear and tooth groove engage to move the slide rod downwards. The slide rod moves stably through the sliding sleeve, which in turn moves the piston downwards. The position of the piston can be observed through the viewing window, and the scale line on one side of the viewing window indicates how much material can be added to the feeding box. During the piston's movement, the telescopic tube on the piston extends and retracts. After the piston reaches the required scale line position, the drive motor stops running. At this time, the material is transferred through the inlet to the telescopic tube, then through the telescopic tube to the discharge port, and finally through the discharge port to the bottom of the feeding box cavity. After the material in the feeding box has been quantitatively added, it can be transferred to the processing equipment through the outlet. This avoids the situation where the feeding equipment does not have a quantitative feeding function and relies on manual or mechanical valve control, which leads to deviations in the amount of material added.

[0013] 2. This utility model uses a limiting plate to fix the drive motor, which makes the drive motor perform better during use and avoids shaking during use, thus preventing the drive motor from running unstablely.

[0014] The limiting block can limit the movement of the slide rod when it moves downward, thus preventing the slide rod from falling out of the sleeve.

[0015] The connecting block can fix the bottom of the slide rod to the connection with the piston, preventing the piston from falling off the slide rod during use.

[0016] When material needs to be discharged from the outlet, it can be controlled by a solenoid valve, making the discharge more convenient. Attached Figure Description

[0023] The following drawings will disclose several embodiments of this utility model. For clarity, many practical details will be described in the following description. However, it should be understood that these practical details should not be used to limit this utility model. That is, in some embodiments of this utility model, these practical details are not essential. In addition, for the sake of simplicity, some conventional structures and components will be shown in the drawings in a simple schematic manner.

[0024] Please see Figure 1-4The present invention relates to a quantitative addition device for the production of chlorobenzene using AABI closed-loop technology, comprising a feeding box 1, a viewing window 6 on the front of the feeding box 1, a scale line 7 on the front of the feeding box 1 located to the left of the viewing window 6, a feed inlet 8 on the right side of the top of the feeding box 1, a discharge outlet 4 at the bottom of the feeding box 1, and a quantitative feeding assembly 9 inside the feeding box 1. The quantitative feeding assembly 9 includes a drive motor 901 located at the top of the feeding box 1, and a gear 908 at the output end of the drive motor 901. A slide rod 905 is provided on one side of gear 908. The surface of slide rod 905 has a toothed groove 909 that matches gear 908. A sliding sleeve 906 is movably connected to the surface of slide rod 905, and the surface of sliding sleeve 906 is fixedly connected to the top of the inner cavity of the feeding box 1. A piston 903 is provided at the bottom of slide rod 905. A material discharge port 9011 is provided on the right side of the inner cavity of piston 903. The top of material discharge port 9011 is connected to a telescopic tube 907, and the top of telescopic tube 907 is fixedly connected to the feed inlet 8. When it is necessary to add material to the processing equipment, this utility model first... The drive motor 901 operates, driving the gear 908 to rotate. The gear 908, in conjunction with the tooth groove 909, moves the slide rod 905 downwards. The sliding sleeve 906, working in conjunction with the slide rod 905, stabilizes the movement. The slide rod 905 then moves the piston 903 downwards. The downward position of the piston 903 can be observed through the viewing window 6, and the scale line 7 on one side of the viewing window 6 indicates the amount of material that can be added to the feeding box 1. During the movement of the piston 903, the telescopic tube 907 on the piston 903 extends and retracts accordingly. After the stopper 903 moves to the required scale line 7, the drive motor 901 stops running. At this time, the material is transferred through the feed port 8 into the telescopic tube 907, through the telescopic tube 907 to the discharge port 9011, and through the discharge port 9011 to the bottom of the inner cavity of the feeding box 1. After the material in the feeding box 1 is quantitatively added, it can be transferred to the processing equipment through the discharge port 4. This avoids the situation where the feeding equipment does not have the function of quantitative feeding and relies on manual or mechanical valve control, which leads to the deviation of the added amount.

[0025] The bottom of the drive motor 901 is engaged with the limiting plate 902, and the bottom of the limiting plate 902 is fixedly connected to the feeding box 1. The limiting plate 902 can fix the drive motor 901, so that the drive motor 901 performs better when in use and avoids the drive motor 901 shaking during use, which would lead to unstable operation of the drive motor 901.

[0026] A limiting block 9010 is fixedly connected to the top of the slide rod 905, and the diameter of the limiting block 9010 is larger than the diameter of the slide rod 905. Through the limiting block 9010, the slide rod 905 can be limited when it moves downward, thus preventing the slide rod 905 from falling out of the sliding sleeve 906.

[0027] The bottom of the slide rod 905 is fixedly connected to the piston 903 by a connecting block 904, and the bottom of the slide rod 905 is located at the center of the top of the piston 903. The connecting block 904 can fix the bottom of the slide rod 905 to the piston 903, preventing the piston 903 from falling off the slide rod 905 during use.

[0028] A mounting plate 3 is fixedly connected to the bottom of the surface of the feeding box 1, and the inner cavity of the mounting plate 3 is provided with mounting holes 2.

[0029] The inner cavity of the discharge port 4 is equipped with a solenoid valve 5, and the input end of the solenoid valve 5 is electrically connected to the external controller. When it is necessary for the discharge port 4 to leak material, it can be controlled by the solenoid valve 5, which makes it more convenient for the discharge port 4 to leak material.

[0030] When using this invention: When it is necessary to add material to the processing equipment, firstly, drive motor 901 runs, which drives gear 908 to rotate. Gear 908, in conjunction with tooth groove 909, drives slide rod 905 to move downward. Sliding sleeve 906, in conjunction with slide rod 905, stabilizes the movement. Sliding rod 905 drives piston 903 to move downward. The downward position of piston 903 can be observed through viewing window 6. The scale line 7 on one side of viewing window 6 indicates the amount of material that can be added to the feeding box 1. During the movement of piston 903, the extension on piston 903... The retracting tube 907 extends and retracts accordingly. After the piston 903 moves to the required scale line 7, the drive motor 901 stops running. At this time, the material is transferred into the retracting tube 907 through the feed port 8, and then transferred to the discharge port 9011 through the retracting tube 907. The material is then transferred to the bottom of the inner cavity of the feeding box 1 through the discharge port 9011. After the material in the feeding box 1 is quantitatively added, it can be transferred to the processing equipment through the discharge port 4. This avoids the situation where the feeding equipment does not have the function of quantitative feeding and relies on manual or mechanical valve control, which leads to the deviation of the added amount.
