Description

Technical Field

[0001] The utility model relates to the technical field of resin solvent recovery, and more specifically, to a solvent recovery device based on macroporous resin adsorption. Background Art

[0002] Macroporous resin is a polymer adsorption resin with a special macroporous structure. It is formed by a specific synthesis method to form a large number of pores in the polymer network. The diameter of these pores is generally greater than 2 nanometers, and some can even reach hundreds of nanometers, so they are called "macroporous". Macroporous resins are characterized by high specific surface area and pore volume, which makes them excellent in adsorption performance and can effectively adsorb various molecules, including organic, inorganic and biological macromolecules.

[0003] In some chemical production processes, solvent utilization efficiency and cost control are very important factors. By using macroporous resins to adsorb and recover solvents, production costs can be greatly reduced and environmental pollution can be reduced.

[0004] The existing solvent recovery device for macroporous resin adsorption introduces high-temperature steam into a resin adsorption tank containing macroporous resin. The water vapor in the steam desorbs the substances adsorbed on the macroporous resin again, forming a liquid that flows into a condenser through a pipeline for cooling. The cooled liquid passes through a stratification device to separate the solvent from water, thereby achieving the purpose of solvent recovery. However, in the existing resin adsorption tank, the resins are mostly stacked, resulting in a low reaction rate between the steam added to the resin adsorption tank and the macroporous resin, and may cause a situation where some macroporous resins do not react fully with the high-temperature steam, resulting in a reduced solvent extraction rate.

[0005] Therefore, in order to solve the above technical problems, the present application proposes a solvent recovery device based on macroporous resin adsorption. Utility Model Content

[0006] In view of the shortcomings of the prior art, the purpose of the utility model is to provide a solvent recovery device based on macroporous resin adsorption.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a solvent recovery device based on macroporous resin adsorption comprises a workbench and a scraper, and a shell is connected to the top of the workbench;

[0008] A flattening mechanism is arranged inside the shell and is used to flatten the macroporous resin placed inside the shell;

[0009] An adjustment mechanism is arranged inside the housing and is used to adjust the position of the scraper;

[0010] The flattening mechanism includes a motor, and the number of the motors is multiple groups. One side of the multiple groups of motors is installed on one side of the shell, and the output shafts of the multiple groups of motors pass through one side of the shell and are connected to one end of the screw. The other end of the screw is installed in the shell through a bearing. The outer surface of the screw is threadedly connected to a threaded seat, one side of the threaded seat is connected to a cross plate, and the bottom of the cross plate is connected to a scraper through an adjustment mechanism.

[0011] Preferably, a plurality of groups of filter plates are connected inside the shell, and a macroporous resin is placed above the filter plates. The water vapor in the steam causes the adsorbed substances on the macroporous resin to be desorbed again, forming a liquid that passes through the filter plates.

[0012] Preferably, the adjustment mechanism includes bolts, and the bottom of the cross plate is connected to two groups of mounting blocks. One side of the two groups of mounting blocks is provided with threaded holes. One side of the scraper is penetrated by a first through hole and a second through hole. The outer surface of the bolt can penetrate the first through hole or the second through hole and be threadedly connected to the threaded hole. The bolt passes through the first through hole to connect to the mounting block, so that the scraper is at a certain distance from the filter plate to flatten the macroporous resin. The bolt passes through the second through hole to connect to the mounting block, so that the scraper is close to the filter plate to push away the macroporous resin placed on the filter plate.

[0013] Preferably, a gap is formed between one end of the filter plate and the inner wall of the shell, and the pushed macroporous resin falls from the gap to the bottom of the shell, which is convenient for removal.

[0014] Preferably, the inner wall of the shell is connected to multiple groups of baffles to prevent the macroporous resin from moving to the bottom of the screw, thereby avoiding damage to the macroporous resin due to movement of the threaded seat.

[0015] Preferably, the top of the shell is connected to the steam pipe, the bottom of the shell is connected to one end of the first pipe, the other end of the first pipe is connected to the top of the condenser, the bottom of the condenser is connected to one end of the second pipe, the other end of the second pipe is connected to the stratification device, the two sides of the stratification device are symmetrically connected to one end of the third pipe, and the other ends of the two groups of third pipes are respectively connected to the solvent tank and the wastewater tank.

[0016] Preferably, the top of the workbench is connected to a condenser, a layering device, a solvent tank and a waste water tank.

[0017] Preferably, a door is installed at the opening of the shell to facilitate replacement of the macroporous resin inside the shell.

[0018] Compared with the prior art, the utility model has the following beneficial effects:

[0019] 1. By setting up a flattening mechanism, the motor can be controlled to drive the screw to rotate, drive the threaded seat to move, drive the scraper to move, flatten the macroporous resin placed on the filter plate, increase the contact area between the macroporous resin and the high-temperature steam, and enable the macroporous resin to fully react with the high-temperature steam, thereby solving the problem of insufficient reaction between some macroporous resins and high-temperature steam, resulting in a reduced solvent extraction rate.

[0020] 2. By adjusting the mechanism and the gap, the bolt can be passed through the second through hole to thread the threaded block, so that the scraper is close to the filter plate. The scraper is driven to move by the control motor to push the macroporous resin above the filter plate to fall from the gap to the bottom of the shell, which is convenient for replacing the macroporous resin in the shell.

[0021] 3. By setting a baffle, the macroporous resin can be prevented from moving to the bottom of the screw, thereby avoiding damage to the macroporous resin caused by the movement of the threaded seat. BRIEF DESCRIPTION OF THE DRAWINGS
