Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of chlorinated benzene, specifically, and relates to a feeding device for chlorobenzene preparation. BACKGROUND

[0002] Chlorobenzene is a colorless liquid with a boiling point of 132.2°C. During World War I, it was mainly used to produce picric acid, which was needed for military explosives. From 1940 to 1960, it was used in large quantities to produce the DDT (DDT) insecticide. After 1960, DDT was gradually replaced by other pesticides with high efficiency and low residual toxicity, and the demand for chlorobenzene has been declining. It is mainly used as a solvent for ethyl cellulose and many resins, and is used to produce various other benzene intermediates, such as nitrochlorobenzene. Dinitrochlorobenzene is an organic compound with strong oxidizing and corrosive properties. It can react with strong bases and strong acids to form corresponding salts. Under certain conditions, it can also undergo electrophilic substitution reactions, replacing chlorine atoms or nitro groups. At high temperatures, it may undergo polymerization to form polymers. Dinitrochlorobenzene is a hazardous chemical with irritant and toxic properties. It can irritate the skin and eyes, and may even cause allergic reactions. During use, appropriate protective measures should be taken, such as wearing protective glasses, gloves, and masks, to avoid direct contact with the skin and eyes. In summary, dinitrochlorobenzene is an important organic compound with wide application in organic synthesis and pharmaceutical industry, but due to its toxicity and danger, special attention should be paid to safety during use.

[0003] The patent specification with publication number CN209109028U discloses a raw material mixing and feeding device for 2,4-dinitroaniline chlorination reaction, which includes a shell. The upper surface of the shell is connected with a bearing a. The bearing a is sleeved with a rotating shaft a, and the top end of the rotating shaft a is fixedly connected with the output shaft of a motor. The outer surface of the rotating shaft a is fixedly connected with stirring rods. The number of stirring rods is several, and the stirring rods are evenly arranged on the outer surface of the rotating shaft a. By setting the feeding pipe, rotating shaft b, driving bevel gear, and driven bevel gear, when different raw materials need to be added to the shell, the different raw materials are put into different feeding pipes, and the rotating shaft a drives the stirring rods to rotate, so that the stirring rods can mix the raw materials in the shell well. Therefore, workers do not need to manually pour multiple raw materials into the shell one by one, but can pour multiple raw materials into the shell at the same time, which facilitates the operation of workers and improves work efficiency.

[0004] However, in the implementation of the related technology, it is found that the above technical solution has the following problems: the above device is not convenient for cleaning the feeding assembly and the stirring pieces inside the device during use. If it is used for a long time, it is difficult to clean the inside of the device, which will affect the environment inside the device and make the user feel uncomfortable when opening and using it. Therefore, further improvement is needed. Utility Model Content

[0005] This invention proposes a feeding device for the preparation of dinitrochlorobenzene, which solves the problem in related technologies that make it inconvenient to clean the feeding components and devices to ensure the internal environment.

[0006] The technical solution of this utility model is as follows:

[0007] A feeding device for the preparation of dinitrochlorobenzene includes a processing tank, a connecting valve inside the processing tank, multiple support rods fixedly connected to the outside of the processing tank, a base plate fixedly connected to the bottom of the multiple support rods, a limiting shell fixedly connected to one side of the top of the processing tank, a feeding shell inside the limiting shell, a viewing window embedded in the front of the feeding shell, a sealing plate inside the feeding shell, and a pulling plate fixedly connected to the outer end of the sealing plate.

[0008] Preferably, the outer surface of the feeding shell is in contact with the limiting shell, and the sealing plate is adapted to and in contact with the interior of the feeding shell.

[0009] Preferably, a rotating top plate is movably connected to one side of the top of the feeding shell via a rotating shaft, and an inlet pipe is embedded on one side of the top of the treatment tank.

[0010] Preferably, a motor is fixedly connected to the top of the processing tank, and the motor is fixedly connected to a rotating rod via an output shaft.

[0011] Preferably, the rotating rod is connected to the processing tank via a bearing, and multiple sets of support rods are fixedly connected to the outside of the rotating rod.

[0012] Preferably, a circular plate is fixedly connected to the outside of the rotating rod, and a rod body is fixedly connected to one side of the outside of the circular plate.

[0013] Preferably, the circular plate and the rod are both located at the top of the stirring rod, and an adapter plate is fixedly connected to one end of the rod.

[0014] Preferably, the adapter plate is shaped like a zigzag, and one side of the adapter plate is in contact with the inner wall of the processing tank.

[0015] The working principle and beneficial effects of this utility model are as follows:

[0016] In this utility model, when it is necessary to clean the feeding shell, the staff will pull the feeding shell upward. During the movement, the feeding shell will separate from the limiting shell. Then the staff can clean the inside of the feeding shell. This avoids the situation where it is difficult to clean the inside of the previous feeding container, which affected the use effect. It solves the problem of it being inconvenient to clean the feeding component and thus ensure the internal environment.

[0017] In this invention, the stirring rod stirs and mixes the liquid during rotation. Simultaneously, the rotating rod drives the circular plate and the rod body to rotate, and the rod body drives the adapter plate to rotate. During the rotation of the adapter plate, it not only mixes the internal liquid but also cleans and scrapes off the scale on the inner wall, facilitating subsequent rinsing.
