Description

Technical Field

[0001] The utility model relates to the technical field of reaction kettles, and particularly relates to a nitrogen conveying mechanism for the protective atmosphere of a tank body. Background Art

[0002] Generally understood, a reaction kettle is a container for physical or chemical reactions. Through the structural design and parameter configuration of the container, functions such as heating, evaporation, cooling, and mixing at low and high speeds required by the process are realized.

[0003] Reaction kettles are widely used in fields such as petroleum, chemical industry, rubber, pesticides, dyes, medicine, and food. They are pressure vessels used to complete processes such as vulcanization, nitrification, hydrogenation, alkylation, polymerization, and condensation, such as reactors, reaction pots, decomposition pots, polymerization kettles, etc.; the materials are generally carbon manganese steel, stainless steel, zirconium, nickel-based (Hastelloy, Monel, Inconel) alloys, and other composite materials.

[0004] When the tank body of the reaction kettle is reacting, it is often necessary to convey protective nitrogen into the reaction kettle to avoid oxidation of the materials. The traditional gas pipeline is arranged at the top of the tank body, and the contact between nitrogen and the materials is slow, thus affecting the reaction process.

[0005] After retrieval, [Chinese Utility Model] CN201220551677.0, a nitrogen conveying structure for a reaction kettle, in which a nitrogen outlet pipe that discharges gas upward is provided at the bottom of the reaction kettle body. The pipe orifice of the nitrogen outlet pipe is communicated with an air outlet cover. The upper surface of the air outlet cover is an upwardly convex arc surface, and the lower surface is a downwardly convex arc surface. A plurality of air outlet holes are respectively distributed on the arc surfaces, and the air outlet holes are distributed from dense to sparse from the inside to the outside. The structure of the utility model is reasonably designed. Through the structural design of the air outlet cover, the nitrogen coming out of multiple air holes reacts with the materials at the same time, increasing the contact area between nitrogen and the materials, and at the same time accelerating the reaction process and improving work efficiency.

[0006] However, although this reaction kettle can increase the contact area between nitrogen and the materials, the air holes cannot be closed and are easily blocked.

[0007] Therefore, how to provide a nitrogen conveying mechanism for the protective atmosphere of a tank body to solve the problems existing in the prior art is of great significance for its application. Content of the Utility Model

Both of the two fixed columns are rotatably connected with rotating sleeves, and both of the two rotating sleeves are fixedly connected with sealing plates;

[0011] A rotary joint is installed at the bottom end of the stirring tank body, the rotary air outlet end of the rotary joint is connected with the oval box body through a connecting pipe, air holes are formed in both sides of the oval box body, the sealing plate is hermetically connected with the oval box body, and an air inlet pipe is connected to the rotary joint.

[0012] Preferably, a torsion spring is sleeved at the bottom end of the fixed column, and the fixed column and the rotating sleeve are elastically connected through the torsion spring.

[0014] Preferably, the two sealing plates are symmetrically arranged, and the output shaft of the electric motor can rotate in both forward and reverse directions.

[0015] Compared with the prior art, the beneficial effects of the present utility model are:

[0016] The present utility model adopts the method of bottom air intake for nitrogen delivery. During use, nitrogen is delivered to the rotary joint through the air inlet pipe, and then nitrogen is delivered to the oval box body through the connecting pipe. At this time, the electric motor drives the oval box body to rotate through the stirring shaft and the one-way transmission bearing, so as to open the sealing plates on both sides. Nitrogen is delivered to the stirring tank body through the air holes on both sides of the oval box body, so that nitrogen can fully react with the material. When the nitrogen delivery is completed, the electric motor rotates in reverse. At this time, the stirring shaft no longer drives the oval box body to rotate through the one-way transmission bearing, and the sealing plates on both sides seal the air holes under the action of the torsion spring, avoiding material blockage of the air holes.
