Description

Technical Field

[0001] This utility model relates to the field of ammonia synthesis tower technology, and in particular to a protective locking device for the cylinder of an ammonia synthesis tower. Background Technology

[0002] The ammonia synthesis tower is a device used under high pressure and high temperature to catalyze the reaction of nitrogen and hydrogen to synthesize ammonia. The ammonia synthesis tower is the heart of the ammonia synthesis plant and is a complex reactor. The protective locking device of the ammonia synthesis tower body is mainly used to protect and lock the ends of the ammonia synthesis tower body and its sealing surface.

[0003] The existing literature on ammonia synthesis tower and sealing surface protection device (CN217614600U) can be referenced. The reference uses the sealing cavity formed by the inner cylinder section and the ring plate to seal and protect the double cone sealing surface at the end of the ammonia synthesis tower body. The outer cylinder section supports the ring plate and the inner cylinder section. The fixed connection component fixes the ring plate, inner cylinder section and outer cylinder section into a whole at the end of the ammonia synthesis tower body, so that the sealing and protection are stable and continuous, and the double cone sealing surface at the end of the ammonia synthesis tower body is effectively protected.

[0004] Currently, the top of the ammonia synthesis tower is generally sealed with a top cover. As shown in the above literature, the top cover needs to be fixed to the top of the tower with bolts. The bolt fixing method makes the sealing performance of the tower completely dependent on the tightness of the bolt connection. If the bolts loosen under the influence of the external environment, it will directly affect the connection stability of the top cover. In this case, it is difficult for the staff to detect and deal with it in time, increasing the time of gas leakage. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a protective locking device for the ammonia synthesis tower body. This invention connects the fixing ears at both ends of the mounting base to the top of the tower body, seals and protects the ends through the cooperation of sealing plugs and rubber sealing sleeves, and simultaneously inserts two insert blocks into the inner groove of the positioning seat through the operation of the internal drive assembly of the mounting base, thereby providing secondary positioning of the mounting base and effectively preventing it from loosening.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A protective locking device for an ammonia synthesis tower shell includes: a mounting base and positioning seats fixed on both sides of the end of the shell. The mounting base is provided with a driving assembly, which includes two threaded sleeves that move in opposite directions. One end of each threaded sleeve is fixed with two telescopic rods, and the other end of each telescopic rod is connected to a plug. The plugs are inserted into the inner groove of the positioning seat. A push switch is embedded and fixed in the inner groove of the positioning seat. An indicator light electrically connected to the push switch is provided above the positioning seat.

[0008] The present invention is further configured as follows: the drive assembly includes: a drive motor mounted inside the mounting base via a fixing block; and a first bevel gear connected to the output end of the drive motor.

[0009] The present invention is further configured such that the drive assembly includes: two threaded rods rotatably connected inside the mounting base; and a second bevel gear fixed to the end of the threaded rod, wherein both second bevel gears mesh with the first bevel gear at a 90° angle.

[0010] The present invention is further configured such that the threaded sleeves are all threadedly connected to the outside of the threaded rod, and through openings are provided on both sides of the mounting base for the linear movement of the telescopic rod.

[0011] The present invention is further provided with fixing ears at both ends of the mounting base, the fixing ears being tightly attached to the upper part of the cylinder and connected thereto by bolts.

[0012] The present invention is further configured such that a sealing plug is connected to the lower part of the mounting base, and the sealing plug is inserted into the upper opening of the cylinder.

[0013] The present invention is further configured such that a rubber sealing sleeve is integrally connected to the outside of the sealing plug, and the rubber sealing sleeve is located in the upper opening of the cylinder and in close contact with the inner wall.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. The protective locking device for the ammonia synthesis tower body connects the fixing ears at both ends of the mounting base to the top of the tower body. The end is sealed and protected by the cooperation of the sealing plug and the rubber sealing sleeve. At the same time, the operation of the internal drive component of the mounting base inserts two plugs into the inner groove of the positioning base, thereby limiting the mounting base a second time. Even if the bolts loosen, the stability of the mounting base connection can be guaranteed.

[0016] 2. When the two inserts of the protective locking device for the ammonia synthesis tower body are inserted into the inner groove of the positioning seat, since the inner groove of the positioning seat is embedded with a press switch, pressing the press switch with the insert will cause the indicator light connected to the press switch to light up, indicating that the connection of the mounting seat is stable. Conversely, if the light goes out, it indicates that the connection tightness has decreased, which makes it easy for the staff to discover and deal with this special situation in a timely manner.

[0026] Reference Figure 1-4 A protective locking device for an ammonia synthesis tower shell includes: a mounting base 2, the bottom of which is tightly attached to the upper surface of the shell 1; a sealing plug 5 integrally connected to the bottom of the mounting base 2; the sealing plug 5 is inserted into the upper opening of the shell 1; the radius of the sealing plug 5 is slightly smaller than the upper opening of the shell 1; and a rubber sealing sleeve 4 integrally connected to the outside of the sealing plug 5; the rubber sealing sleeve 4 is also located at the upper opening of the shell 1 and is tightly connected to the inner wall to improve the sealing effect.

[0027] Specifically, such as Figure 2 As shown, fixing ears 6 are provided at both ends of the mounting base 2. The fixing ears 6 are close to the upper surface of the cylinder 1. The two fixing ears 6 can be connected to the cylinder 1 by bolts, thereby completing the fixing of the mounting base 2.

[0028] Furthermore, it can be referenced Figure 1 Positioning seats 3 are connected to both ends of the cylinder 1, and the surface of the positioning seats 3 is provided with square inner grooves.

[0029] Furthermore, a drive assembly is installed inside the mounting base 2.

[0030] Driver components such as Figure 4 As shown, the driving source of the drive assembly is the drive motor 13. The drive motor 13 is fixed inside the mounting base 2 by the fixing block 12. The output end of the drive motor 13 is connected to the first bevel gear 14.

[0031] Specifically, the mounting base 2 of this device is cylindrical and has two square protrusions. Inside the mounting base 2, there are two threaded rods 17 rotatably connected. The ends of the two threaded rods 17 are connected to the square protrusions (which can only rotate). Threaded sleeves 16 are threadedly connected to the outside of the threaded rods 17.

[0032] Furthermore, a second bevel gear 15 is fixed at the other end of the threaded rod 17, and both second bevel gears 15 mesh with the first bevel gear 14 at a 90° angle.

[0033] In this embodiment, the operation of the drive motor 13 can drive the first bevel gear 14 to rotate, which in turn drives the second bevel gear 15, which are symmetrical on both sides, to rotate in the opposite direction, so that the two threaded rods 17 rotate in the opposite direction. At the same time, the two threaded sleeves 16 are symmetrically distributed around the center of the mounting base 2, so that the two threaded sleeves 16 move in the opposite direction around the center.

[0034] For details, please refer to Figure 2 As shown, two telescopic rods 7 are connected to one side of the threaded sleeve 16, and the other end of each telescopic rod 7 is fixed with an insert block 8.

[0035] Meanwhile, through holes 9 are provided on both sides of the mounting base 2 for linear displacement of the telescopic rod 7, and the insert 8 can be inserted into the inner groove of the positioning base 3.

[0036] Specifically, such as Figure 3 As shown, each positioning base 3 has a push switch 10 embedded and fixed in its inner groove, and each positioning base 3 has an indicator light 11 above it. The indicator lights 11 are electrically connected to the push switch 10.

[0037] Therefore, as Figure 1 and Figure 4 As shown, when both inserts 8 are fully inserted into the inner groove of the positioning seat 3, both threaded sleeves 16 are located in the two square protrusions. When both inserts 8 press the push switch 10, the two indicator lights 11 light up, indicating that the connection of the mounting seat 2 is in a stable state. When the two indicator lights 11 go out, it means that the inserts 8 are separated from the push switch 10, the connection tightness decreases, and it is convenient to deal with it in time.

[0038] Working principle: When using this utility model, the fixing ears 6 at both ends of the mounting base 2 are connected to the top of the cylinder 1. The ends are sealed and protected by the cooperation of the sealing plug 5 and the rubber sealing sleeve 4. At the same time, the operation of the internal drive component of the mounting base 2 inserts two plugs 8 into the inner groove of the positioning base 3, thereby limiting the mounting base 2 for a second time. Even if the bolts are loose, the stability of the connection of the mounting base 2 can be guaranteed. When the two plugs 8 are inserted into the inner groove of the positioning base 3, since the inner groove of the positioning base 3 is embedded with a press switch 10, when the plug 8 presses the press switch 10, the indicator light 11 electrically connected to the press switch 10 lights up to indicate that the connection of the mounting base 2 is in a stable state. Conversely, the light goes out to indicate that the connection tightness has decreased, which makes it easy for the staff to find out and deal with this special situation in time.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
