Description

Technical Field

[0001] This utility model relates to the field of flame retardant production technology, specifically to an emergency spray pipe device for an absorption tower used in flame retardant production. Background Technology

[0002] The flame retardant is a high molecular weight phosphoric acid flame retardant, suitable for use in automotive interior parts and polyurethane foam for various furniture. It exhibits good resistance to yellowing, excellent thermal stability, and long-lasting flame retardancy, while also reducing product costs. In the production process of phosphorus-based and bromine-based flame retardants, the absorption tower is a key piece of equipment for treating exhaust gases. Exothermic chemical reactions often occur inside the tower. If abnormal increases in temperature or pressure occur due to cooling failure, raw material imbalance, or other reasons, it can easily lead to serious accidents such as tower overflow, explosion, or toxic gas leakage. Therefore, an emergency spray pipe device must be installed in the inlet flue of the absorption tower to spray cooling water and cool the high-temperature flue gas.

[0003] The existing connection between the emergency spray pipe and the inlet flue of the absorption tower used for flame retardant production is unstable, which easily leads to the leakage of high-temperature flue gas from the connection. Therefore, it does not meet the current requirements. In response, we propose an emergency spray pipe device for the absorption tower used for flame retardant production. Utility Model Content

[0004] The purpose of this utility model is to provide an emergency spray pipe device for an absorption tower used in the production of flame retardants, so as to solve the problem mentioned in the background art that the connection between the existing emergency spray pipe for the production of flame retardants and the inlet flue of the absorption tower is unstable and easily leads to the leakage of high-temperature flue gas from the connection.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an emergency spray pipe device for an absorption tower used in flame retardant production, comprising a smoke inlet pipe and a spray pipe. A connecting seat is fixedly connected to the outer side of the upper end of the smoke inlet pipe. One end of the spray pipe passes through the connecting seat and extends into the interior of the smoke inlet pipe. A ring-shaped docking seat is fixedly connected to the outer surface of the spray pipe. One end of the docking seat extends into the interior of the connecting seat and fits against the inner wall of the connecting seat. A ring-shaped sealing gasket is fixedly connected to the bottom end of the docking seat and to the outer surface of the spray pipe. The outer surface of the sealing gasket fits tightly against the inner wall of the connecting seat and the connection point of the smoke inlet pipe.

[0006] Preferably, the connecting seat has a movable cavity inside, and a threaded groove is provided above the movable cavity and at the top of the connecting seat. The top of the connecting seat has a threaded rod that passes through the threaded groove and extends into the movable cavity.

[0007] Preferably, a limiting block is slidably connected inside the movable cavity, and a spring is fixedly connected between one side of the limiting block and one side of the inner wall of the movable cavity. A driving groove is provided on the upper end of the limiting block near the spring.

[0008] Preferably, the inner wall of the drive groove is inclined on the side near the spring, and one end of the threaded rod that penetrates into the movable cavity extends into the interior of the drive groove, with one side of the bottom end of the threaded rod in sliding contact with the inclined surface of the drive groove.

[0009] Preferably, in the spring's natural state, the end of the limiting block furthest from the spring passes through the movable cavity and extends into the interior of the connecting seat.

[0010] Preferably, the outer surface of the docking seat is provided with a limiting groove that matches the limiting block, and one end of the limiting block extending through into the interior of the connecting seat is inserted into the corresponding limiting groove.

[0011] Compared with the prior art, the beneficial effects of this utility model are: This invention achieves a stable connection between the spray pipe and the smoke inlet pipe by passing one end of the spray pipe through the connecting seat and extending into the interior of the smoke inlet pipe. This ensures that the outer surfaces of the mating seat and the sealing gasket are tightly fitted with the connection between the connecting seat and the smoke inlet pipe. Then, the threaded rod is rotated in the opposite direction, causing the threaded rod to rotate in the threaded groove and move towards the interior away from the moving cavity. At this time, one side of the bottom end of the threaded rod slides into contact with the inclined surface on the driving groove side of the limiting block, thereby moving away from the bottom end inside the driving groove. At this time, one end of the limiting block, under the elastic push of the spring, extends through and into the interior of the connecting seat and inserts into the corresponding limiting groove on the mating seat, thereby stably connecting the spray pipe and the smoke inlet pipe.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] Please see Figures 1 to 4 This utility model provides an embodiment of an emergency spray pipe device for an absorption tower used in flame retardant production, comprising a smoke inlet pipe 1 and a spray pipe 2. A connecting seat 3 is fixedly connected to the outer side of the upper end of the smoke inlet pipe 1. One end of the spray pipe 2 passes through the connecting seat 3 and extends into the interior of the smoke inlet pipe 1. A ring-shaped docking seat 4 is fixedly connected to the outer surface of the spray pipe 2. One end of the docking seat 4 extends into the interior of the connecting seat 3 and fits against the inner wall of the connecting seat 3. A ring-shaped sealing gasket 5 is fixedly connected to the bottom end of the docking seat 4 and to the outer surface of the spray pipe 2. The outer surface of the sealing gasket 5 fits tightly against the inner wall of the connecting seat 3 and the connection point of the smoke inlet pipe 1. The sealing gasket 5 improves the sealing performance of the connection between the spray pipe 2 and the smoke inlet pipe 1.

[0016] The connecting seat 3 has a movable cavity 301 inside. Above the movable cavity 301 and at the top of the connecting seat 3, a threaded groove 302 is provided. The top of the connecting seat 3 has a threaded rod 8 that is threaded through the threaded groove 302 and extends into the movable cavity 301. A limiting block 6 is slidably connected inside the movable cavity 301. A spring 7 is fixedly connected between one side of the limiting block 6 and one side of the inner wall of the movable cavity 301. A driving groove 601 is provided on the upper end of the limiting block 6 near the spring 7. The inner wall of the driving groove 601 near the spring 7 is inclined. One end of the threaded rod 8 that penetrates into the movable cavity 301 extends into the driving groove 601, and one side of the bottom end of the threaded rod 8 slides in contact with the inclined surface of the driving groove 601.

[0017] By rotating the threaded rod 8 in the opposite direction, the threaded rod 8 rotates in the threaded groove 302 and moves towards the interior away from the movable cavity 301. At this time, one side of the bottom end of the threaded rod 8 slides into contact with the inclined surface on one side of the drive groove 601 on the limiting block 6, thereby moving away from the bottom end inside the drive groove 601.

[0018] In the natural state of the spring 7, the end of the limiting block 6 away from the spring 7 passes through the movable cavity 301 and extends into the interior of the connecting seat 3. The outer surface of the docking seat 4 is provided with a limiting groove 401 that matches the limiting block 6. The end of the limiting block 6 that extends into the interior of the connecting seat 3 is inserted into the corresponding limiting groove 401.

[0019] One end of the limiting block 6 extends through the interior of the connecting seat 3 under the elastic push of the spring 7, and is inserted into the corresponding limiting groove 401 on the docking seat 4, thereby stably connecting the spray pipe 2 and the smoke inlet pipe 1.

[0020] When using the emergency spray pipe device for the absorption tower in flame retardant production, the threaded rod 8 is rotated clockwise, causing the threaded rod 8 to rotate in the threaded groove 302 and move along the inclined surface on one side of the drive groove 601 on the limiting block 6 towards the bottom end of the drive groove 601. At this time, the limiting block 6 is driven to compress the spring 7 on one side, causing the limiting block 6 to move and be housed inside the movable cavity 301. Then, by passing one end of the spray pipe 2 through the connecting seat 3 and extending into the interior of the smoke inlet pipe 1, the outer surfaces of the mating seat 4 and the sealing gasket 5 are tightly fitted with the connection between the connecting seat 3 and the smoke inlet pipe 1. Then, the device is rotated in the opposite direction. The threaded rod 8 rotates in the threaded groove 302 and moves inward away from the movable cavity 301. At this time, one side of the bottom end of the threaded rod 8 slides in contact with the inclined surface of the drive groove 601 on the limiting block 6, thereby moving away from the bottom end inside the drive groove 601. At this time, one end of the limiting block 6 extends through the interior of the connecting seat 3 under the elastic push of the spring 7, and is inserted into the corresponding limiting groove 401 on the mating seat 4, thereby stably connecting the spray pipe 2 and the smoke inlet pipe 1. Furthermore, the sealing gasket 5 improves the sealing performance of the connection between the spray pipe 2 and the smoke inlet pipe 1.
