Description

Technical Field

[0001] This utility model belongs to the technical field of high-temperature resistant polyacrylamide polymerization equipment, and particularly relates to a reaction vessel for high-temperature resistant polyacrylamide polymerization. Background Technology

[0002] High-temperature resistant polyacrylamide requires a reaction vessel for polymerization. The vessel body is the main part of the reaction vessel and is used to contain the reaction materials. It is usually made of different materials, such as carbon manganese steel, stainless steel, zirconium, nickel-based alloys, etc., to meet the requirements of corrosion resistance, high temperature resistance and other properties of different reactions.

[0003] To ensure sufficient liquid discharge potential energy, some reactor bodies are erected relatively high. When staff need to inspect them, they need to climb up a ladder on one side to observe or operate the upper part of the reactor body. However, conventional fixed ladders extend outwards over a large area, resulting in conventional elevated reactor bodies occupying a large amount of ground space.

[0004] To address these issues, we propose a high-temperature resistant reaction vessel for polyacrylamide polymerization. Utility Model Content

[0005] The purpose of this invention is to solve the problem that conventional elevated reactors occupy a large amount of ground space, and to propose a high-temperature resistant polyacrylamide polymerization reactor.

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

[0007] A high-temperature resistant polyacrylamide polymerization reactor includes a reactor body. A support is fixedly connected to the lower end of the reactor body. A first step, a second step, and a third step are slidably installed inside the support. The upper end of the first step is in movable contact with the second step, and the upper end of the second step is in movable contact with the third step. When maintenance of the reactor body is required, the first, second, and third steps are pulled outwards, allowing the user to climb from the first and second steps to the third step to observe or operate the upper part of the reactor body. Alternatively, the first, second, and third steps are pushed inwards, retracting them into the support, reducing ground occupancy, ensuring road accessibility, and improving ground utilization.

[0008] Preferably, a handrail is fixedly connected to the side of the first step, and the handrail is in movable contact with the support frame. The handrail serves as a barrier on the outside of the first, second, and third steps, increasing the safety factor during climbing.

[0009] Preferably, the support includes a frame, and a support block is fixedly connected inside the frame. After the first step, the second step, and the third step are pulled out, the support block is used to support the base of the first step, the second step, and the third step respectively, ensuring the stability of the first step, the second step, and the third step in their unfolded state.

[0010] Preferably, the first step includes a first support shell, and a first limiting frame is fixedly connected to the rear of the first support shell. After the first step is pulled outward, it is supported on the ground by the first support shell and supported on the support block by the first limiting frame, so that the top of the first support shell is kept parallel to the ground.

[0011] Preferably, the first step further includes a first linkage rod, the lower part of which is fixedly connected to the rear part of the first limiting frame. When the first step is pulled outward, the first support shell acts on the first limiting frame, which in turn drives the first linkage rod to move. The first linkage rod then pushes the second step, facilitating the unfolding of the second step together with the first step.

[0012] Preferably, the second step includes a second support shell, and a second limiting frame is fixedly connected to the rear of the second support shell. After the second step is pulled out, it is supported on the first support shell by the second support shell, and simultaneously supported on the support block by the second limiting frame, so as to keep the second support shell horizontal.

[0013] Preferably, the second step further includes a second linkage rod, the lower part of which is fixedly connected to the rear part of the second limiting frame. When the second step is pulled outward, the third step is pushed outward using the second linkage rod, making it convenient for the third step to unfold together with the second step.

[0014] Preferably, the third step includes a third support shell, and a stop bar is fixedly connected to the rear of the third support shell. After the third step is unfolded outward, the front of the third support shell is supported on the second support shell, and the rear of the third support shell is supported on the support block, so as to keep the top of the third support shell level.

[0015] In summary, the technical effects and advantages of this utility model are as follows:

[0016] 1. When the reactor body needs to be inspected, pull out the first step, the second step, and the third step, and climb up to the third step in sequence. Stand on the third step to observe or operate the upper part of the reactor body; push the first step, the second step, and the third step inward to retract them into the support, reduce the ground occupation rate, ensure smooth road access, and improve ground utilization.

[0017] 2. Use handrails to block the outside of the first, second, and third steps to increase the safety factor when climbing.

[0018] 3. When the first step is pulled outward, the first support shell acts on the first limiting frame, which in turn drives the first linkage rod to move. The first linkage rod then pushes the second step, making it easy for the second step to unfold together with the first step. Attached Figure Description

[0025] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments.

[0026] like Figure 1 As shown, a high-temperature resistant polyacrylamide polymerization reactor includes a reactor body 1. A support 2 is fixedly connected to the lower end of the reactor body 1. A first step 3, a second step 4, and a third step 5 are slidably installed inside the support 2. The upper end of the first step 3 is in contact with the second step 4, and the upper end of the second step 4 is in contact with the third step 5.

[0027] like Figure 1 As shown, a handrail 6 is fixedly connected to the side of the first step 3, and the handrail 6 is in contact with the support 2. The handrail 6 is used to block the outside of the first step 3, the second step 4, and the third step 5, increasing the climbing safety factor.

[0028] like Figure 1 and 2As shown, the support 2 includes a frame 21, with support blocks 22 fixedly connected inside the frame 21. The support blocks 22 are distributed below the first step 3, the second step 4, and the third step 5, and are in movable contact with each of these steps. After the first step 3, the second step 4, and the third step 5 are pulled out, the support blocks 22 support the base of each step, ensuring the stability of the unfolded state of the first step 3, the second step 4, and the third step 5.

[0029] like Figure 1 and 3 As shown, the first step 3 includes a first support shell 31, and a first limiting frame 32 is fixedly connected to the rear of the first support shell 31. The lower end of the first support shell 31 is in movable contact with the ground. The first support shell 31 and the first limiting frame 32 are slidably connected within the frame 21, and the first limiting frame 32 is in movable contact with the support block 22. After the first step 3 is pulled outward, it is supported on the ground by the first support shell 31 and supported on the support block 22 by the first limiting frame 32, so that the top of the first support shell 31 remains parallel to the ground.

[0030] like Figure 1 and 3 As shown, the first step 3 also includes a first linkage rod 33, the lower part of which is fixedly connected to the rear part of the first limiting frame 32. When the first step 3 is pulled outward, the first support shell 31 acts on the first limiting frame 32, and the first limiting frame 32 drives the first linkage rod 33 to move, thereby pushing the second step 4.

[0031] like Figure 1 and 4 As shown, the second step 4 includes a second support shell 41, and a second limiting frame 42 is fixedly connected to the rear of the second support shell 41. The lower end of the second support shell 41 is in movable contact with the first support shell 31. The second support shell 41 and the second limiting frame 42 are slidably installed inside the frame 21, and the second limiting frame 42 is in movable contact with the support block 22. After the second step 4 is pulled out, the second support shell 41 is supported on the first support shell 31, and the second limiting frame 42 is supported on the support block 22, so that the second support shell 41 remains horizontal.

[0032] like Figure 1 and 4 As shown, the second step 4 also includes a second linkage rod 43, the lower part of which is fixedly connected to the rear part of the second limiting frame 42. When the second step 4 is pulled outward, the second linkage rod 43 is used to push the third step 5 outward, so that the third step 5 unfolds together with the second step 4.

[0033] like Figure 1 and 5As shown, the third step 5 includes a third support shell 51, with a stop bar 52 fixedly connected to the rear of the third support shell 51. The third support shell 51 is slidably installed inside the frame 21, and the rear of the third support shell 51 is movably supported on the support block 22 on the upper part of the frame 21. The stop bar 52 is blocked inside the frame 21, and the lower end of the third support shell 51 is movably supported on the second support shell 41. After the third step 5 is unfolded outward, the front of the third support shell 51 is supported on the second support shell 41, while the rear of the third support shell 51 is supported on the support block 22, keeping the top of the third support shell 51 horizontal.

[0034] Working principle: When the reactor body 1 needs to be inspected, pull out the first step 3, the second step 4, and the third step 5, and climb up to the third step 5 in sequence. Stand on the third step 5 to observe or operate the upper part of the reactor body 1; push the first step 3, the second step 4, and the third step 5 inward, so that the first step 3, the second step 4, and the third step 5 retract into the support 2, reducing the ground occupation rate and ensuring smooth passage.
