Description

Technical Field

[0001] The utility model relates to the technical field of chemical equipment, in particular to a reaction kettle dropping device. Background Art

[0002] Isocyanate prepolymer and amino resin complete instantaneous reaction in the reactor. Currently, the addition of prepolymer to the reactor is completed by single-channel dropwise addition. Currently, the addition of prepolymer to the reactor is completed through an addition tube. The liquid drips into the reactor in a relatively concentrated manner and is often reacted before it has time to diffuse, resulting in uneven mixing of the reaction liquid in the reactor. Due to the failure of the prepolymer to diffuse, the reaction is uneven, resulting in a local reaction, which in turn produces a solid mass phenomenon, affecting product quality.

[0003] In order to solve the above problems, the prior art patent (CN20448513U) discloses a dropping device for a reactor, which is composed of a high-level tank, a discharge control pipe and a disperser. The high-level tank is located above the reactor, one end of the discharge control pipe is connected to the high-level tank, and the other end of the discharge control pipe extends into the reactor and is connected to the disperser. The disperser is located in the upper part of the reactor, and the disperser is composed of a dispersion pipe and an annular dripping pipe. The annular dripping pipe and the discharge control pipe are connected through the dispersion pipe. There are evenly distributed dropping holes on the annular dripping pipe, and the dropping holes are arranged toward the bottom wall of the reactor. The aperture of the dropping hole is smaller than the aperture of the dispersion pipe, and the aperture of the dispersion pipe is smaller than the aperture of the discharge control pipe; the prepolymer flows from the high-level tank into the disperser above the reaction liquid in the reactor through the discharge control pipe, and drips into the reaction liquid through the annular dripping pipe. The porous dripping allows the prepolymer to diffuse, so that the reaction liquid is mixed evenly to avoid the formation of solid clumps.

[0004] However, in the above-mentioned prior art, when the liquid material to be added needs to be replaced, the material barrel needs to be cleaned again to introduce the liquid material, resulting in a slow connection speed. In addition, if the material barrel is not cleaned thoroughly, it is easy to cause a mixing reaction of the liquid materials. Utility Model Content
