Description

Technical Field

[0001] The utility model relates to a feeding device for a reaction kettle. Background Art

[0002] During the surfactant processing, when the surfactant is injected into the reactor for mixing reaction, when other auxiliary materials need to be added, auxiliary feeding will be carried out through the feeding device. The structure of the feeding device in the prior art is relatively simple, and the basic defect is that the auxiliary materials fall into the surface of the materials in the reactor. In many cases, due to uneven stirring, the added auxiliary materials remain on the surface, thereby affecting the uniformity of stirring in the reactor. If the blanking head is located at the bottom and extends too far into the reactor, there may be a situation where the stirring force is too large to damage the blanking pipe. In view of this situation, it is urgent to solve it. Utility Model Content

[0016] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention.

[0017] like Figure 1 As shown, a feeding device for a reactor is characterized in that it comprises:

[0018] The reactor body has an end cover 1 at its upper end;

[0019] A feed assembly, which is arranged on the surface of the reactor body;

[0020] The reactor body has a three-layer structure, which includes an inner shell 22 , a middle installation layer 21 and an outer protective shell 2 from inside to outside. The feed assembly is arranged in the middle installation layer 21 .

[0021] Furthermore, a lock buckle 11 is provided between the end cover 1 and the reactor body.

[0022] Furthermore, the inner shell 22 is provided with a plurality of corrosion-resistant flow nozzles, and each flow nozzle is provided with a one-way valve 2211 .

[0023] Furthermore, the feed assembly includes a feed pipe and an injection joint 213 connected to the inlet end of the feed pipe, and the outlet end of the feed end is connected to a adapter 2212 connected to the flow nozzle.

[0024] Furthermore, the outer protective shell 2 is disposed outside the middle installation layer 21 and wraps the feed assembly, and the injection connector 213 extends out of the outer protective shell 2 .

[0025] Furthermore, an electric heater 211 is installed on the intermediate installation layer 21, and the electric heater 211 is connected to an electric heating wire 211 attached to the inner shell 22. The electric heater 211 is used to heat the electric heating wire 211 on the inner shell 22 to increase the temperature of the liquid in the inner shell 22 and accelerate the reaction.

[0026] The present application sets up a three-layer structure of the reactor body, and sets a circulation nozzle on the inner shell 22 for discharging auxiliary materials. The one-way valve 2211 is used to prevent the liquid in the reactor body from flowing back. The auxiliary materials are transported through the feeding pipe 212, and the materials are added through the injection joint 213. The conventional open feeding head is easy to enter impurities, and the injection feeding method discharges the impurities. The outer protective shell 2 is used to protect the feeding assembly. Most of the feeding pipes 212 of the existing feeding devices extend into the interior of the reactor, which may interfere with the stirring work or be hit and damaged by the stirring. The flow joint 221 for outflowing auxiliary materials of the present application is set on the inner shell 22 and can be set close to the bottom of the reactor for better dissolution.

[0027] The technical solution of the above utility model provides a solution that is significantly different from the prior art to address the technical problem that the prior art solution is too single. The parts not involved in the technical solution of this application are the same as the prior art or can be implemented by using the prior art and will not be described in detail.

[0028] The technical solutions in the above embodiments have clearly and completely described the contents of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
