Description

Technical Field

[0001] This utility model belongs to the technical field of catalyst addition equipment, specifically relating to a connection structure for a titanium catalyst pipeline. Background Technology

[0002] Titanium catalysts play a crucial role in modern chemical engineering, especially in polymerization and selective oxidation reactions. They are characterized by high activity, high selectivity, and environmental friendliness (typically low toxicity).

[0003] If the catalyst is added too quickly, the mixing is uneven, or the cooling system fails, the massive reaction triggered instantly by the catalyst will release enormous amounts of heat. If the heat cannot be removed in time, the temperature of the reaction system will rise sharply. The temperature rise will then cause the reaction rate to increase exponentially, forming a vicious cycle of "higher temperature → accelerated reaction → more heat release → even higher temperature," ultimately leading to runaway reaction, material spillage (material ejected from the reactor), or explosion. Utility Model Content

[0004] The present invention aims to solve the technical problems existing in the prior art and provide a connection structure for titanium catalyst pipelines.

[0005] The above-mentioned technical problems of this utility model are mainly solved by the following technical solution: a connection structure for a titanium catalyst pipeline, including a connecting pipeline, the top of which has a flared portion, the inner ring of which has a threaded inner ring, the outer ring of which has an outer flared portion, and a through hole penetrating the connecting pipeline at the outer flared portion, a mechanical seal inserted at the through hole, an inner sleeve provided inside the connecting pipeline corresponding to the through hole, the inner sleeve fixed to the connecting pipeline, an inner rotating cylinder inserted into the mechanical seal, the inner rotating cylinder inserted into the inner sleeve, the top of the inner sleeve penetrating downwards and through the inner rotating cylinder to provide a material passage, an auxiliary pipeline connected to the outer end of the inner rotating cylinder, a first valve provided at the top of the auxiliary pipeline, and a second valve provided at the connection between the auxiliary pipeline and the inner rotating cylinder.

[0006] Preferably, the flared opening is threaded with an insulation cover, and the outer side of the insulation cover is threaded with a door, which seals and shields the auxiliary pipe.

[0007] Preferably, a material feeding channel for slow material stopping is formed between the first valve and the second valve located in the auxiliary pipeline.

[0008] Preferably, the inner rotating cylinder has a feed chamber inside for the reaction of the catalyst and the raw materials.

[0009] The beneficial effects of this utility model are as follows: By inserting an inner sleeve into one side of the feeding pipe and a rotatable inner cylinder into the inner sleeve, and connecting an auxiliary pipe to the outside of the inner cylinder, the temperature of the internally flowing raw material can be guided, so that the whole can be preheated at the same temperature as the internal temperature. With the first and second valves at both ends of the auxiliary pipe, the titanium catalyst can be initially stopped, and the subsequent feeding can be more sufficient. At the same time, a feed port is opened between the inner sleeve and the inner cylinder, which can be used to ensure that the raw material and the titanium catalyst react fully when the raw material is rushed in. At the same time, the degree of fusion between the two is further increased before entering the reactor, so that the reaction is more complete after entering the reactor and avoids violent reaction due to insufficient reaction.

[0013] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0014] Example: A connection structure for a titanium catalyst conduit, such as... Figures 1-2As shown, the device includes a connecting pipe 11, with a flared portion 12 formed at the top of the connecting pipe 11. A threaded inner ring 13 is formed on the inner ring of the top of the flared portion 12. The device is characterized by an outer flared portion 14 on one side of the outer ring of the connecting pipe 11, and a through hole penetrating the connecting pipe 11 at the outer flared portion 14. A mechanical seal 15 is inserted into the through hole. An inner sleeve 2 is provided inside the connecting pipe 11 corresponding to the through hole, and the inner sleeve 2 is fixed to the connecting pipe 11. An inner rotating cylinder 3 is inserted inwardly into the mechanical seal 15. The inner rotating cylinder 3 is provided with a feed chamber 35 for the reaction of catalyst and raw materials. The inner rotating cylinder 3 is inserted into the inner sleeve 2. The top of the inner sleeve 2 passes through the inner rotating cylinder 3 and has a feed port 36. The outer end of the inner rotating cylinder 3 is connected to an auxiliary pipe 31. The top of the auxiliary pipe 31 is provided with a first valve 32. The connection between the auxiliary pipe 31 and the inner rotating cylinder 3 is provided with a second valve 33. A feeding channel 34 for slow stopping of material is formed between the first valve 32 and the second valve 33 in the auxiliary pipe 31.

[0015] An insulation cover 41 is threadedly connected at the flared opening 14. A cover door 42 is threadedly connected to the outside of the insulation cover 41. The insulation cover 41 seals and shields the auxiliary pipe 31.

[0016] The principle of this invention is as follows: By opening the cover 42 or rotating the insulation cover 41 to detach it from the outer flare 14, the first valve 32 is opened. After adding the titanium catalyst to be reacted, the first valve 32 is closed. Then, depending on the requirements, the second valve 33 is partially opened, and the auxiliary pipe 31 is rotated so that its output end faces upward. This allows the feed port 36 on the inner rotating cylinder 3 to communicate with the feed port 36 on the inner sleeve 2. At this time, the pressurized raw material is rushed into the feed chamber 35, guiding the titanium catalyst located in the feeding channel 34 towards the feed chamber 35, so that it can quickly fuse with the raw material. Then, the insulation cover 41 is closed. When a second addition is required, the insulation cover 41 is opened again. At this time, the second valve 33 must be closed first, and then the first valve 32 is opened to add the titanium catalyst.

[0017] Finally, it should be noted that the above embodiments are merely representative examples of this utility model. Obviously, this utility model is not limited to the above embodiments and many variations are possible. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model should be considered to fall within the protection scope of this utility model.
