Description

Technical Field

[0001] This utility model relates to a deacidification tower for DMF recovery, belonging to the field of dimethylformamide technology. Background Technology

[0002] Dimethylformamide is an organic compound, a colorless and transparent liquid. It is both a widely used chemical raw material and a widely used excellent solvent. It is miscible with water and most organic solvents and has good solubility for a variety of organic and inorganic compounds. A deacidification tower is required when recycling dimethylformamide.

[0003] When deacidifying dimethylformamide, a deacidification tower is required for recovery due to the high formic acid content. The internal structure of the deacidification tower is usually the same as that of a packed tower. In a packed tower, the packing grid is generally fixed in place, making it inconvenient to adjust its position and height according to the required amount of packing material. Furthermore, after prolonged use, the packing may be corroded, scaled, or physically damaged by formic acid, requiring replacement or maintenance. If it cannot be quickly disassembled and reassembled, the entire deacidification tower may need to be shut down for an extended period, making it inconvenient for operators.

[0004] Therefore, a deacidification tower for DMF recovery is proposed. Utility Model Content

Each of the connecting rods 207 has a movable block 208 fixedly installed at its bottom.

[0023] By setting up the installation component 2, and through the rotation of the turntable 201, the moving rod 203 can cooperate with the slot 202 and the moving groove 213 to allow the insert block 206 to be inserted into the inner cavity of the insertion hole 102. Firstly, insertion holes 102 are opened at different heights in the deacidification tower body 101, which makes it convenient for operators to install the installation component 2 at different heights according to the packing requirements. At the same time, the insert block 206 can be easily retracted and extended, which can improve the disassembly and assembly of the installation component 2 as a whole, improve the convenience of the overall equipment installation, and facilitate its maintenance after long-term use. Moreover, the components of the installation component 2 are all made of bidirectional stainless steel, which ensures its stability in high acidity environments and makes it convenient for operators to use.

[0024] Example 2 Figure 1-6 As shown, in one embodiment, the bottom of each movable block 208 is threaded with a mounting bolt 209, and the top of the mounting bolt 209 is threaded to the inner surface of the housing 103. An arc-shaped groove 210 is formed at the bottom of the housing 103, and a connecting rod 207 passes through the inner cavity of the arc-shaped groove 210 and extends to the bottom of the housing 103. Slots 211 are formed on the surface of the housing 103, and six insert blocks 206 pass through the inner cavities of the six slots 211 and are inserted into the inner cavity of the insertion holes 102. The size of the insert blocks 206 corresponds to the inner cavity of the insertion holes 102. The dimensions of the cavities are matched, and the inner cavities of the insert block 206 and the insertion hole 102 are in the same horizontal direction. An annular groove 212 is provided in the inner cavity of the housing 103. The outer side of the turntable 201 is slidably connected to the inner cavity of the annular groove 212. A movable groove 213 is provided at the top of the inner cavity of the housing 103. The tops of the six movable rods 203 are slidably connected to the inner cavities of the six movable grooves 213. A limiting groove 214 is provided at the bottom of the housing 103. The bottoms of the six connecting blocks 204 are slidably connected to the inner cavities of the six limiting grooves 214.

[0025] By setting the mounting bolt 209, the position of the moving block 208 can be limited to prevent the connecting rod 207 from shifting, thus affecting the stability of the insertion block 206 inserted into the cavity of the insertion hole 102. By setting the arc groove 210, the movement of the housing 103 can be limited to prevent it from shifting during movement, thus affecting the stability of the installation of the housing 103. By setting the slot 211, the direction of the movement of the insertion block 206 can be limited to prevent it from shifting during movement. By setting the annular groove 212, the rotation of the turntable 201 can be limited to prevent it from shifting during rotation. By setting the moving groove 213, the movement of the moving rod 203 can be limited to prevent it from shifting during movement, thus affecting the operation of the insertion block 206. By setting the limiting groove 214, the movement of the connecting block 204 can be limited to prevent it from shifting during movement.

[0026] In operation, when the housing 103 needs to be completely disassembled, the mounting bolts 209 are released from their limiting position on the moving block 208. Then, the moving block 208 is pulled to move, simultaneously driving the connecting rod 207 and the turntable 201 to move. The turntable 201 rotates, causing the slot 202 to move. The slot 202, through its engagement with the moving slot 213, causes the moving rod 203 to drive the connecting block 204 and the insert block 206 to move inwards. At this time, the connecting block 204 compresses the spring 205, and the insert block 206... Remove the insert block 206 from the inner cavity of the socket 102 to complete the disassembly of the housing 103. After the housing 103 is repaired, align the insert block 206 with the inner cavity of the socket 102 to be inserted according to the required filling position. Repeat the above steps again. Then release the moving block 208. At this time, the spring 205 pushes the connecting block 204 to move outward again due to the loss of force. The connecting block 204 drives the insert block 206 to move synchronously, so that the insert block 206 is inserted into the inner cavity of the socket 102, thereby completing the installation of the housing 103.
