Description

Technical Field

[0001] This utility model relates to the field of purification technology, specifically to an N-methylpyrrolidone purification device with adsorption function. Background Technology

[0002] Chinese patent CN112094216A discloses a high-purity N-methylpyrrolidone purification device with adsorption function, including an adsorption assembly I, an adsorption group II, a semiconductor assembly, an outer cover, a fixed plate A, a filter element A, a fixed plate B, a filter element B, a fixed plate C, a filter element C, a tank, a motor, a rotating shaft, a side cover, a molecular sieve membrane sleeve, a support mesh, activated carbon, a heat insulation cover, a partition, a semiconductor cooler, a flow tube I, and a flow tube II. Firstly, through a multi-stage preliminary purification design, it not only facilitates the preliminary adsorption and filtration of large particles and magnetic particles in N-methylpyrrolidone, but also facilitates replacement and disassembly, avoiding clogging problems after long-term use. Secondly, the use of a centrifugal molecular two-stage purification mechanism can greatly increase the adsorption effect and improve the purification efficiency. Finally, the semiconductor temperature control structure allows for simultaneous heating and evaporation of moisture in the preceding process of N-methylpyrrolidone, while also timely cooling to ensure it reaches its final state as quickly as possible. This patent uses multiple sets of filter elements to perform preliminary adsorption and filtration of raw materials. The filter elements are inserted or removed through the same opening, which requires the raw materials to stop passing through the I adsorption component when the filter elements are loaded or unloaded, which is not conducive to improving purification efficiency.

[0003] Based on this, a purification device for N-methylpyrrolidone with adsorption function was designed to solve the problem. Utility Model Content

[0004] The purpose of this utility model is to provide an N-methylpyrrolidone purification device with adsorption function to solve the above-mentioned technical problems.

[0005] To achieve the above objectives, the utility model provides the following technical solution: an N-methylpyrrolidone purification device with adsorption function, comprising a pretreatment component and a purification component. The discharge end of the pretreatment component and the inlet end of the purification component are interconnected. The pretreatment component includes a shell, and multiple sets of filter components are provided inside the shell. The multiple sets of filter components are arranged sequentially along the extension direction of the shell. Multiple sets of mounting components that match the filter components are provided inside the shell. The mounting components include mounting cylinders, which are embedded in the shell. The top of the mounting cylinder is provided with an installation port and a disassembly port for mounting and disassembling the filter components. The openings of the installation port and the disassembly port are provided with caps that can be detachably connected by bolts. The installation port and the disassembly port are arranged parallel to each other. The multiple sets of filter components are arranged sequentially in the mounting cylinder along the axis of the shell. The multiple sets of filter components slide along the inner wall of the mounting cylinder from the installation port toward the disassembly port. By setting the installation port and disassembly port parallel to each other on the upper side of the installation cylinder, the installation and disassembly of the filter components can be carried out at different positions in the installation cylinder. When replacing the filter components, it is not necessary to remove the filter components first before installing the replacement filter components, ensuring that at least one set of filter components is installed in the installation cylinder.

[0006] Furthermore, the disassembly port is located on the side of the mounting port near the feed end of the housing.

[0007] By adopting the above technical solution, the disassembly port is located on the side close to the feed end of the housing, which helps to place the new filter component at the end of the old filter component away from the feed end, and avoids the large particles adsorbed on the filter component falling off when it is disassembled, so that it can directly enter the subsequent process.

[0008] Furthermore, the mounting cylinder is provided with two sets of first guide rails symmetrically arranged inside. The two ends of the first guide rails are respectively connected to the mounting port and the disassembly port. The top of the filter assembly is provided with a slider that matches the first guide rails. The two ends of the slider are respectively slidably matched with the two sets of first guide rails.

[0009] By adopting the above technical solution, the first guide rail and the slider abut against each other, which helps to support and restrict the filter assembly and ensure that the filter assembly moves horizontally toward the disassembly port.

[0010] Furthermore, the first guide rail is provided with a transmission assembly, which includes a transmission belt. The transmission belt is driven to rotate by a drive motor located in the mounting cylinder. The slider abuts against the upper side of the transmission belt, and the upper side of the transmission belt moves from the mounting port toward the disassembly port.

[0011] By adopting the above technical solution, the transmission belt in the transmission assembly is driven to rotate by the drive motor, and the bottom wall of the slider abuts against the transmission belt. The rotation of the transmission belt drives the slider and the filter assembly to move towards the disassembly port, which facilitates the control of the position of the filter assembly in the installation cylinder.

[0012] Furthermore, the transmission belt is provided with multiple sets of abutment plates at equal intervals, and the abutment plates abut against and match the side of the slider away from the disassembly port.

[0013] By adopting the above technical solution, multiple sets of abutment plates abut and match with multiple sets of sliders on the side away from the disassembly port, which is beneficial for pushing the slider to move within the first guide rail.

[0014] Furthermore, the bottom of the mounting cylinder is provided with the transmission assembly, the transmission belt abuts against the bottom wall of the filter assembly, and the abutment plate abuts against the side of the filter assembly away from the disassembly port.

[0015] By adopting the above technical solution, the bottom of the mounting cylinder is equipped with the same transmission component. The transmission component matches the bottom of the filter component, which helps to make the upper and lower ends of the filter component move synchronously and ensure that the filter component moves horizontally.

[0016] Furthermore, the bottom of the mounting cylinder is provided with a groove, the bottom of the filter assembly extends into the groove, a sealing plate is slidably provided on the side of the groove that is close to the feed end of the housing, the side of the sealing plate away from the feed end of the housing abuts and matches with the filter assembly, and a first elastic element is provided between the side of the sealing plate away from the filter assembly and the inner wall of the groove.

[0017] By adopting the above technical solution, the first elastic element can be made of a spring. The first elastic element drives the sealing plate to move to abut against and match the filter assembly, wrapping the lower end of the filter assembly in the slot, covering the gap between the filter assembly and the bottom wall of the mounting cylinder, and ensuring that the raw material passes through the filter assembly.

[0018] Compared with the prior art, the beneficial effects of this utility model are: by setting the installation port and disassembly port parallel to each other on the upper side of the installation cylinder, the installation and disassembly of the filter component are carried out at different positions on the installation cylinder. When replacing the filter component, it is not necessary to remove the filter component before installing the replacement filter component, ensuring that at least one set of filter components is provided in the installation cylinder.

[0026] Combination Figure 1-3 :

[0027] Reference Figure 1 , 2Figure 3 shows an N-methylpyrrolidone purification device with adsorption function, comprising a pretreatment component 1 and a purification component 2. The discharge end of the pretreatment component 1 and the inlet end of the purification component 2 are interconnected. The pretreatment component 1 includes a housing 11, and multiple sets of filter components 3 are arranged sequentially along the extending direction of the housing 11. Multiple sets of mounting components 4 that match the filter components 3 are provided inside the housing 11. The mounting components 4 include mounting cylinders 41, which are embedded in the housing 11. The top of the mounting cylinders 41 is provided with mounting for loading and unloading the filter components 3. The mounting port 42 and the disassembly port 43 are equipped with covers that can be detachably connected by bolts. The mounting port 42 and the disassembly port 43 are arranged parallel to each other. Multiple sets of filter components 3 are sequentially arranged inside the mounting cylinder 41 along the axis of the housing 11. The multiple sets of filter components 3 slide along the inner wall of the mounting cylinder 41 from the mounting port 42 toward the disassembly port 43. By arranging the mounting port 42 and the disassembly port 43 parallel to each other inside the mounting cylinder 41, the mounting cylinder 41 can simultaneously load and unload multiple sets of filter components 3. At least one set of filter components 3 is provided inside the mounting cylinder 41. The disassembly port 43 is located on the side of the mounting port 42 near the feed end of the housing 11. By arranging the mounting port 42 and the disassembly port 43 parallel to each other on the upper side of the mounting cylinder 41, the installation and disassembly of the filter components 3 are carried out at different positions in the mounting cylinder 41. When replacing the filter components 3, it is not necessary to remove the filter components 3 before installing the replacement filter components 3, ensuring that at least one set of filter components 3 is provided inside the mounting cylinder 41. The disassembly port 43 is located on the side near the feed end of the housing 11, which helps to place the new filter assembly 3 at the end away from the feed end of the old filter assembly 3, and prevents the large particles adsorbed on the filter assembly 3 from falling off when it is disassembled, so that it can directly enter the subsequent process.

[0028] Reference Figure 1 , 2As shown in Figure 3, the mounting cylinder 41 has two sets of symmetrically arranged first guide rails 44. The two ends of the first guide rails 44 are connected to the mounting port 42 and the disassembly port 43, respectively. The top of the filter assembly 3 has a slider 31 that matches the first guide rails 44. The two ends of the slider 31 slide and match the two sets of first guide rails 44. A transmission assembly 5 is provided inside the first guide rails 44. The transmission assembly 5 includes a transmission belt 51, which is driven to rotate by a drive motor located inside the mounting cylinder 41. The slider 31 abuts against the upper side of the transmission belt 51, and the upper side of the transmission belt 51 moves from the mounting port 42 towards the disassembly port 43. Multiple sets of abutment plates 52 are equidistantly arranged on the transmission belt 51, and the abutment plates 52 abut against the side of the slider 31 away from the disassembly port 43. The bottom of the mounting cylinder 41 has the transmission assembly 5, where the transmission belt 51 abuts against the bottom wall of the filter assembly 3, and the abutment plates 52 abut against the side of the filter assembly 3 away from the disassembly port 43. The first guide rail 44 abuts against the slider, which helps to support and restrict the filter assembly 3, ensuring that the filter assembly 3 moves horizontally towards the disassembly port 43. The transmission belt 51 in the transmission assembly 5 is driven to rotate by a drive motor. The bottom wall of the slider abuts against the transmission belt 51, and the rotation of the transmission belt 51 drives the slider and filter assembly 3 to move towards the disassembly port 43, facilitating control of the position of the filter assembly 3 within the mounting cylinder 41. Multiple sets of abutment plates 52 abut against the sides of multiple sets of sliders away from the disassembly port 43, which helps to push the slider to move within the first guide rail 44. The bottom of the mounting cylinder 41 is equipped with the same transmission assembly 5. The transmission assembly 5 matches the bottom of the filter assembly 3, which helps to make the upper and lower ends of the filter assembly 3 move synchronously, ensuring that the filter assembly 3 maintains horizontal movement.

[0029] Reference Figure 1 , 2 As shown in Figure 3, the bottom of the mounting cylinder 41 is provided with a slot 6, and the bottom of the filter assembly 3 extends into the slot 6. A sealing plate 61 is slidably provided on the side of the slot 6 that is close to the feed end of the housing 11. The side of the sealing plate 61 away from the feed end of the housing 11 abuts against the filter assembly 3. A first elastic element 62 is provided between the side of the sealing plate 61 away from the filter assembly 3 and the inner wall of the slot 6. The first elastic element 62 can be made of a spring. The first elastic element 62 drives the sealing plate 61 to move until it abuts against the filter assembly 3, wrapping the lower end of the filter assembly 3 in the slot 6, covering the gap between the filter assembly 3 and the bottom wall of the mounting cylinder 41, and ensuring that the raw material passes through the filter assembly 3.

When replacing the filter assembly 3, it is not necessary to remove the filter assembly 3 before installing the replacement filter assembly 3, ensuring that at least one set of filter assembly 3 is provided in the installation cylinder 41.

[0032] The disassembly port 43 is located on the side near the feed end of the housing 11, which helps to place the new filter assembly 3 at the end away from the feed end of the old filter assembly 3, and prevents the large particles adsorbed on the filter assembly 3 from falling off when it is disassembled, so that it can directly enter the subsequent process.

[0033] The first guide rail 44 and the slider abut against each other, which helps to support and restrict the filter assembly 3 and ensure that the filter assembly 3 moves horizontally toward the disassembly port 43.

[0034] In the transmission assembly 5, the transmission belt 51 is driven to rotate by the drive motor. The bottom wall of the slider and the transmission belt 51 abut against each other. The rotation of the transmission belt 51 drives the slider and the filter assembly 3 to move towards the disassembly port 43, which facilitates the control of the position of the filter assembly 3 in the mounting cylinder 41.

[0035] Multiple sets of abutting plates 52 respectively abut against and match with multiple sets of sliders on the side away from the disassembly port 43, which is conducive to pushing the slider to move within the first guide rail 44.

[0036] The bottom of the mounting cylinder 41 is equipped with the same transmission component 5. The transmission component 5 matches the bottom of the filter component 3, which helps to make the upper and lower ends of the filter component 3 move synchronously and ensures that the filter component 3 moves horizontally.

[0037] The first elastic element 62 can be made of a spring. The first elastic element 62 drives the sealing plate 61 to move and match with the filter assembly 3, wrapping the lower end of the filter assembly 3 in the slot 6, covering the gap between the filter assembly 3 and the bottom wall of the mounting cylinder 41, and ensuring that the raw material passes through the filter assembly 3.
