Description

Technical field:

[0001] The invention relates to the technical field of a tubular reactor construction foundation, and more specifically to an auxiliary device for constructing a high-efficiency tubular reactor. Background technology:

[0002] 2-Chloronicotinonitrile is a key intermediate of 2-chloronicotinic acid. As an important fine chemical intermediate, 2-chloronicotinic acid is used to synthesize many medical analgesics or anti-inflammatory agents, medical antibiotics, cardiovascular drugs, and agricultural fungicides, insecticides and herbicides. It is produced in a tubular continuous flow reactor in a laboratory using N-oxy-3-cyanopyridine and phosphorus oxychloride as raw materials. The laboratory is a high-efficiency tubular flow reactor for testing the synthesis of 2-chloronicotinonitrile. It is equipped with a number of reaction tubes as reaction containers. The reaction tubes are connected by elbows to form a continuous S-shaped tubular reactor. The number of reaction tubes can be rotated according to the test requirements, that is, the test synthesis is carried out in tubular reactors of different lengths to obtain an ideal length for efficient synthesis.

[0003] When building the tubular reactor, the most troublesome part is the movement and adjustment of the position of the reaction node tube, because the reaction node tube itself is heavy, and there is a feed pipe connected perpendicular to it on the reaction node tube, which cannot roll on the bottom surface. When the elbows are connected, the reaction node tubes are required to be consistent with each other and the ports of the reaction node tubes are flush. In addition, because different tests require tubular reactors of different lengths, the workload of building the tubular reactor is large, so it is necessary to design an auxiliary device that can locate the position of the reaction node tube and facilitate the adjustment of the position of the reaction node tube. Summary of the invention:

Specific implementation manner:

[0023] Embodiment: See Figures 1 to 4 As shown, an auxiliary device for building an efficient tubular reaction device is provided, including a plurality of horizontally distributed bottom channel steels 1. The bottom channel steels 1 are longitudinally arranged and open downward. Horizontally arranged supporting channel steels 2 are respectively erected on the upper end faces of the front and rear ends of the bottom channel steels 1. The supporting channel steels 2 open downward. A plurality of horizontally distributed V-shaped notches 21 are formed on the upper end face of the supporting channel steels 2. A horizontally rectangular slot 22 is formed in the middle of the V-shaped notch 21. A vertical supporting wheel 3 is inserted into the slot 22. The supporting wheel 3 includes a "U"-shaped bracket 31. A horizontal roller 32 is inserted into the bracket 31. A roller shaft 33 is inserted into the roller 32. The two ends of the roller shaft 33 are respectively inserted and fixed at both ends of the upper part of the bracket 31. The bottom of the bracket 31 is fixedly connected to a horizontal linkage plate 4. The linkage plate 4 is inserted into the supporting channel steel 2;

[0024] Vertical studs 5 are respectively inserted and fixed at the front and rear ends of the bottom channel steel 1. The upper ends of the studs 5 pass through the linkage plate 4 and abut against the supporting channel steel 2; A spring 6 is sleeved on the stud 5. The two ends of the spring 6 respectively abut against the linkage plate 4 and the bottom channel steel 1;

[0025] Vertical internal thread pipe columns 7 are respectively inserted at both ends of the supporting channel steel 2. The lower ends of the internal thread pipe columns 7 are screwed on the studs 5 and abut against the linkage plate 4; A horizontal mounting clamp plate 8 is arranged directly above the supporting channel steel 2. The two ends of the mounting clamp plate 8 are sleeved on the internal thread pipe columns 7. A limit retaining ring 71 is formed on the outer wall of the internal thread pipe column 7 on the upper side of the mounting clamp plate 8;

[0026] A number of laterally distributed reaction tube nodes are placed on the supporting channel steel 2. The reaction tube nodes are arranged in the V-shaped notch 21 of the supporting channel steel 2. The clamping plate 8 and the linkage plate 4 are moved downward by tightening the internal threaded pipe column 7. The linkage plate 4 moves downward to drive the supporting wheel 3 back into the supporting channel steel 2. The clamping plate 8 moves downward to cooperate with the supporting channel steel 2 to clamp the reaction tube nodes. Adjacent reaction tube nodes are connected by semicircular bends, thereby realizing that the reaction tube nodes and the bends form a continuous S-shaped tubular reactor.

[0027] The V-shaped notches 21 are evenly distributed on the supporting channel steel 2 in a linear manner. The front and rear V-shaped notches 21 on the two groups of supporting channel steels 2 are directly opposite to each other. The V-shaped notches 21 are used to position the reaction tube nodes so that the reaction tube nodes are evenly distributed on the supporting channel steel 2. Therefore, it is required that the front and rear V-shaped notches 21 do not have misalignment problems.

[0028] The upper end of the outer wall of the roller 32 on the supporting wheel 3 is not higher than the upper end surface of the supporting channel steel 2. The reaction tube can roll on the upper end surface of the supporting channel steel 2 to reach the corresponding V-shaped notch 21. Therefore, it is required that the roller 32 does not extend out of the upper end surface of the supporting channel steel 2 to interfere with the rolling of the reaction tube.

[0029] At the same time, an elastically supported roller 32 is provided in the V-shaped notch 21, which can limit the reaction node tube from completely entering the V-shaped notch 21. With the help of the roller 32, the reaction node tube can be easily rolled over the V-shaped notch 21, so that the reaction node tube can be moved in a rolling manner without lifting the reaction node tube into the corresponding V-shaped notch 21, which is more labor-saving and convenient.

[0030] A regular hexagonal limiting socket 72 is formed on the top of the internally threaded pipe column 7, and the limiting socket 72 can be connected to an internal hexagonal wrench, through which the internally threaded pipe column 7 can be rotated. At the same time, through holes 23 corresponding to the internally threaded pipe column 7 are provided at both ends of the supporting channel steel 2, and the internally threaded pipe column 7 is inserted into the through holes 23.

[0031] The stud 5 and the bottom channel steel 1 are distributed between the V-shaped notch 21 of the supporting channel steel 2, and the front and rear sides of the linkage plate 4 are respectively against the inner walls of the front and rear sides of the supporting channel steel 2. In addition to being connected with the internal threaded pipe column 7, the upper end of the stud 5 can be butt-welded to achieve the stud 5 and the supporting channel steel 2 being fixed together, and then the linkage plate 4 inserted in the supporting channel steel 2 can improve the supporting strength of the supporting channel steel 2 due to the constraint of the stud 5, thereby avoiding the middle part of the supporting channel steel 2 from sinking downward; the clamping plate 8 is located directly above the supporting wheel 3.

[0032] A "冂"-shaped limit bracket 9 is provided between the supporting channel steels 2. The limit bracket 9 includes a horizontal horizontal support plate and vertical support plates formed at both ends of the horizontal support plate. A plurality of limit slots 91 facing the V-shaped notches 21 are formed on the front side of the horizontal support plate; a longitudinal T-shaped insert 92 is formed at the lower end of the vertical support plate;

[0033] The upper end surface of the middle part of the bottom channel steel 1 is fixedly connected with a longitudinal connecting seat 10, and a T-shaped socket 101 is formed on the connecting seat 10, and an outlet penetrating the front end surface of the connecting seat 10 is formed on the bottom surface of the socket 101; the inserting strip 92 on the limit bracket 9 is inserted into the socket 101 of the connecting seat 10, and a horizontal extension plate 93 is formed at the front end of the inserting strip 92, and the extension plate 93 extends from the outlet of the connecting seat 10 and is formed with a plurality of longitudinally distributed pin holes 94, and a T-shaped positioning pin 11 is inserted into the pin hole 94, and the lower end of the positioning pin 11 is inserted on the positioning pin 11;

[0034] Because the reaction tube is generally provided with a feed pipe perpendicular thereto, in order to realize that the feed pipe is erected upwards and conveniently connected to the feed pipe arranged above the tubular reactor, the above-mentioned limiting bracket 9 is additionally provided, and the feed pipe can be inserted into the limiting bayonet 91 of the limiting bracket 9, and the feed pipe can be abutted against the bottom of the limiting bayonet 91 to uniformly set the longitudinal position of the reaction tube;

[0035] There are multiple pin holes 94 . During the adjustment process, unused pin holes 94 can be selected to cooperate with the positioning pin 11 for positioning. When the reaction tube moves, the feed pipe can move in the limit bayonet 91 .

[0036] The horizontal support plate on the position-limiting bracket 9 is located on the upper side of the clamping plate 8 , and the vertical support plates at both ends of the horizontal support plate are distributed on both sides of all the V-shaped notches 21 .

[0037] Working principle: This structure is an auxiliary device for building a high-efficiency tubular reactor. The specific structure of the auxiliary device is a base for carrying the reaction tube. All the reaction tubes required for the test can be set on the base, and the spacing between the reaction tubes carried by the V-shaped notch 21 on the supporting channel steel 2 is consistent;

[0038] When the clamping plate 8 is not installed, although the gravity of the reaction joint tube presses the supporting wheel 3 to move downward to achieve the compression of the spring 6, the reaction joint tube is still mainly supported by the supporting wheel 3, and the side wall on one side of the V-shaped groove 21 thereof serves as an auxiliary support; then the clamping plate 8 and the internal threaded pipe column 7 are installed, but the internal threaded pipe column 7 is not completely tightened. At this time, with the help of the supporting wheel 3, the axial movement of the reaction joint tube is relatively convenient, and then the axial position of the reaction joint tube is adjusted to be consistent; finally, by tightening the internal threaded pipe column 7, the supporting wheel 3 is moved downward and retracted to the supporting channel steel 2, and the clamping plate 8 cooperates with the supporting channel steel 2 to clamp and fix the reaction joint tube.

[0039] The embodiments are used to illustrate the present invention, but not to limit the present invention. Any person skilled in the art may modify the embodiments without violating the spirit and scope of the present invention, and therefore, the scope of protection of the present invention shall be as set forth in the claims of the present invention.
