Description

Technical Field

[0001] This utility model relates to the field of 5-chloroindanone production technology, and in particular to a 5-chloroindanone production apparatus. Background Technology

[0002] The production process of 5-chloroindanone is as follows: chlorobenzene and anhydrous aluminum trichloride are mixed in a reactor, and 3-chloropropionyl chloride is added dropwise to carry out a Friedel-Crafts acylation reaction to generate 3,4'-dichlorophenylpropionone. The product is cyclized under the catalysis of anhydrous aluminum trichloride / sodium chloride or tris(pentafluorophenyl)borane, washed with water and distilled to obtain 5-chloroindanone.

[0003] In existing technologies, 3-chloropropionyl chloride is mostly added dropwise at fixed points, which has a small range and is not conducive to sufficient contact with raw materials. Therefore, we propose a 5-chloroindanone production device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of 3-chloropropionyl chloride, which is mostly added dropwise at fixed points, resulting in a small range and hindering sufficient contact with raw materials. Therefore, a 5-chloroindanone production device is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A 5-chloroindanone production apparatus, comprising:

[0007] The reactor and the top cover that is rotatably mounted on the top of the reactor;

[0008] Two fixing plates are fixedly installed on the outside of the reactor. A support rod is fixedly installed on the top of each fixing plate, and a top plate is fixedly installed on the top of the support rod.

[0011] A vertical fixing hole is provided on the top cover. A placement box is fixedly installed in the vertical fixing hole, and a drip tube is fixedly connected to the bottom of the placement box.

[0012] The drive mechanism, mounted on a fixed plate, is used to drive the top cover and rotating rod to rotate.

[0013] Preferably, the drive mechanism includes a power rod rotatably mounted on a fixed plate, and a first sprocket is fixedly mounted on the top of the power rod.

[0014] Preferably, a second sprocket is fixedly installed on the top of the rotating rod, and the first sprocket and the second sprocket are meshed with the same chain.

[0015] Preferably, a gear is fixedly installed on the outer side of the power rod, and an annular gear plate is fixedly installed on the outer side of the top cover, with the gear meshing with the annular gear plate.

[0016] Preferably, a motor is fixedly installed at the bottom of the fixing plate, and the output shaft of the motor is fixedly connected to the bottom of the power rod.

[0017] Preferably, the reactor is fixedly connected to a discharge pipe, the discharge pipe is equipped with a second valve, and multiple support legs are fixedly installed at the bottom of the reactor.

[0018] Preferably, an annular plate is fixedly installed on the top of the reactor, an annular groove is opened at the bottom of the top cover, the annular plate is located in the annular groove, an annular limiting groove is provided on the outer side of the annular plate, and a limiting block is provided on the inner wall of the annular groove. The top and bottom of the limiting block are in contact with the top inner wall and bottom inner wall of the annular limiting groove, respectively.

[0019] Preferably, the top cover is provided with a feeding pipe, and the feeding pipe is provided with a first valve.

[0020] Compared with the prior art, the advantages of this utility model are:

[0021] This solution uses a motor to drive a power rod to rotate, which in turn drives a gear and a first sprocket to rotate. The first sprocket drives a second sprocket via a chain, which in turn drives a rotating rod to rotate. The rotating rod then drives the stirring blades on it to rotate, thus mixing the raw materials. At the same time, the gear drives a ring-shaped toothed disc to rotate, which in turn drives a top cover to rotate. The top cover then drives a placement box to rotate, which in turn drives a dripping tube to rotate, increasing the dripping range and facilitating more thorough and uniform contact of the raw materials.

[0022] This invention can increase the dripping range while stirring the raw materials, which is more conducive to the full and uniform contact of the raw materials. Attached Figure Description
