Description

Technical Field

[0001] The utility model relates to a reaction kettle for producing p-nitroaniline. Background Art

[0002] A Chinese patent with application number 202122714938.8 discloses a reactor for the production of para-nitroaniline, which can stir and heat the nitroaniline raw material in the reactor body to make the nitroaniline raw material undergo a fermentation reaction; and after the fermentation reaction is completed, the reaction material in the reactor body can be poured out to facilitate the next fermentation reaction.

[0003] The patented reactor for producing para-nitroaniline comprises: a fixed bottom plate, a vertical reactor body arranged above the fixed bottom plate, two support plates fixedly arranged on the top surface of the fixed bottom plate and arranged on the left and right sides of the reactor body, two movable shafts fixedly arranged on the left and right sides of the reactor body and rotatably connected with the two support plates in a one-to-one correspondence, two slot blocks fixedly arranged on the left and right sides of the reactor body, two positioning rods plugged in a one-to-one correspondence with the two support plates and engaged in a one-to-one correspondence with the two slot blocks, a pushing mechanism (the pushing mechanism comprises an electric push rod, a connecting rod, a push plate, etc.) arranged on the rear side of the reactor body and used to push the reactor body to rotate around the two movable shafts, a material injection port arranged on the top of the reactor body, a material discharge port arranged at the bottom of the reactor body, and a stirring mechanism (the stirring mechanism comprises a motor, a rotating shaft rod, a stirring rod, etc.) and a heating mechanism (the heating mechanism comprises an electric heating wire, a heating plate, a heat conducting plate, etc.) arranged on the reactor body.

[0004] The working principle of the patented reactor for the production of p-nitroaniline is as follows:

[0005] The nitroaniline raw material is placed into the reactor body through the injection port, and then the stirring mechanism (the stirring mechanism includes a motor, a rotating shaft rod, a stirring rod, etc.) and the heating mechanism (the heating mechanism includes a heating wire, a heating plate, a heat conducting plate, etc.) work to stir and heat the nitroaniline raw material in the reactor body, so that the nitroaniline raw material undergoes a fermentation reaction;

[0006] After the fermentation reaction of the nitroaniline raw material is completed, the two positioning rods are pulled out from the two slot blocks, and then the pushing mechanism (the pushing mechanism includes an electric push rod, a connecting rod, a push plate, etc.) pushes the reactor body to rotate around the two movable axes, so that the reactor body is in a tilted state, and then the discharge port is opened, and the reaction material in the reactor body can be poured out through the discharge port; after the reaction material in the reactor body is discharged, the reactor body is returned to the normal state; then the two positioning rods are correspondingly inserted into the two slot blocks; so that the next fermentation reaction can be carried out.

[0007] Although the reactor for the production of p-nitroaniline of the patent can stir and heat the nitroaniline raw material in the reactor body to make the nitroaniline raw material undergo a fermentation reaction; and after the fermentation reaction is completed, the reaction material in the reactor body can be poured out so that the next fermentation reaction can be carried out. However, before tilting the reactor body each time, the two locking rods need to be pulled out from the two slot blocks to unlock the two slot blocks; and after the reactor body is straightened each time, the two locking rods need to be inserted into the two slot blocks again to lock the two slot blocks again; and the two locking rods are arranged on the left and right sides of the reactor body, and it is inconvenient or even impossible for an operator to pull out or insert the two locking rods at the same time, so the unlocking and relocking operations of the two slot blocks are relatively inconvenient and need to be improved.
