Description

Technical Field

[0001] This utility model belongs to the technical field of impurity removal devices, and in particular relates to an N-methylpyrrolidone impurity removal device. Background Technology

[0002] According to the published patent CN221867634U, a purification device for the production of N-methylpyrrolidone includes a cylinder. A servo motor is fixedly installed on the inner bottom wall of the cylinder. A turntable is fixedly installed at the output end of the servo motor. A slide rod is slidably installed on the turntable. A base plate is fixedly installed at the bottom end of the slide rod. A drive motor is fixedly installed at the bottom end of the turntable. The drive motor drives a gear to rotate, which in turn drives the slide rod to slide up and down on the turntable, thereby adjusting the height of the filter layer and the activated carbon layer. This allows the bottom filter layer and activated carbon layer, which are blocked by impurities, to move down. However, the following shortcomings still exist:

[0003] The above-mentioned equipment can filter materials by centrifugation. However, it is not convenient to shake the filter plate during filtration, which may cause the filtered impurities to accumulate in the same place on the filter plate, resulting in blockage and reducing the impurity removal efficiency and quality of the device. Therefore, we propose an N-methylpyrrolidone impurity removal device. Utility Model Content

[0004] The purpose of this invention is to provide an N-methylpyrrolidone impurity removal device. Through a shaking mechanism and an auxiliary mechanism, it solves the problem that when the above-mentioned equipment is used, it can filter materials by centrifugation, but it is not convenient to shake the filter plate during filtration. This may cause the filtered impurities to accumulate in the same place on the filter plate, resulting in blockage and reducing the impurity removal efficiency and quality of the device.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is an N-methylpyrrolidone impurity removal device, including a processing box, an injection pipe fixedly connected to the top outer wall of the processing box, a discharge pipe fixedly connected to the outer wall of the end of the processing box away from the injection pipe, and a shaking mechanism provided on the outer wall of the processing box.

[0007] The vibration mechanism includes a motor frame, a motor fixedly connected to the inner wall of the motor frame, a drive shaft fixedly connected to the bottom output end of the motor via a coupling, a convex shaft fixedly connected to the outer wall of the drive shaft, a top plate slidably connected to the inner wall of the processing box, a filter plate fixedly connected to the bottom outer wall of the top plate, several sliding rods slidably connected to the inner wall of the filter plate, several shock-absorbing springs fixedly connected to the outer wall of the top plate near the sliding rods, a bevel gear fixedly connected to the outer wall of the drive shaft away from the motor frame, and an auxiliary mechanism provided on the outer wall of the processing box.

[0008] Furthermore, the outer wall of the motor frame is fixedly connected to the top outer wall of the processing box, the outer walls of several sliding rods are fixedly connected to the top outer wall of the processing box, and the outer walls of several shock-absorbing springs are fixedly connected to the top outer wall of the processing box.

[0009] Furthermore, the auxiliary mechanism includes a fixed shaft, the outer wall of which is rotatably connected to the top outer wall of the processing box, and a second fixed shaft is rotatably connected to the top outer wall of the processing box near the fixed shaft.

[0010] Furthermore, a bevel gear is fixedly connected to the outer wall of the fixed shaft near the bevel gear, and the outer wall of the bevel gear meshes with the outer wall of the bevel gear. Both the outer wall of the fixed shaft and the outer wall of the fixed shaft are fixedly connected to pulleys.

[0011] Furthermore, a belt is driven to the outer wall of the pulley, a slide rail is slidably connected to the inner wall of the processing box, and a rack is fixedly connected to the outer wall of the slide rail near the fixed shaft.

[0012] Furthermore, both the outer wall of the fixed shaft and the outer wall of the second fixed shaft are fixedly connected with half gears. The outer wall of the half gear on the right side meshes with the outer wall of the rack. Several dampers are fixedly connected to the inner wall of the slide rail.

[0013] Furthermore, a scraper is fixedly connected to the bottom outer wall of the damper, and the outer wall of the scraper is slidably connected to the inner wall of the slide rail. Several damping springs are fixedly connected to the outer wall of the scraper near the damper, and the outer walls of the several damping springs are all fixedly connected to the inner wall of the slide rail.

[0014] Furthermore, the inner wall of the scraper is provided with several perforations, and several plugs are slidably connected to the inner wall of the end of the processing box away from the top plate.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model features a convex shaft on the drive shaft. When the equipment is in use, the motor rotates, driving the drive shaft to rotate and causing the convex shaft to rotate. The rotation of the convex shaft can press against the top plate, causing it to vibrate up and down. The up and down vibration of the top plate will cause the filter plate to vibrate up and down and stretch multiple shock-absorbing springs. The up and down vibration of the filter plate can prevent impurities on the filter plate from accumulating in one place, which would reduce the filtration speed of the filter plate. By setting the filter plate, it can achieve efficient filtration and separation of impurities in the material, accurately removing impurities. At the same time, the up and down vibration design of the filter plate during the filtration process can prevent the filtered impurities from accumulating in a local area, effectively preventing clogging of the filtration area and maintaining a high filtration efficiency at all times.

[0017] 2. This utility model incorporates a half-gear on a fixed shaft. During operation, the rotation of the bevel gear drives the rotation of the second bevel gear, which in turn rotates the second fixed shaft. The rotation of the pulley on the second fixed shaft drives the belt, which in turn drives the pulley on the fixed shaft, causing the fixed shaft to rotate in the same direction. The rotation of the fixed shaft and the second fixed shaft drives the half-gear to rotate in the same direction. The rotation of the half-gear drives the rack to move, achieving the goal of simultaneously pushing the separated impurities towards the edge of the filter plate while filtering and removing impurities from the material. This avoids impurity residue affecting the filtration effect and provides convenience for users to collect impurities in the future, simplifying the impurity cleaning process.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-5 As shown, this utility model is an N-methylpyrrolidone impurity removal device, including a processing box 1. A feeding pipe 101 is fixedly connected to the top outer wall of the processing box 1. A discharge pipe 102 is fixedly connected to the outer wall of the processing box 1 away from the feeding pipe 101. A shaking mechanism 2 is provided on the outer wall of the processing box 1.

[0029] The shaking mechanism 2 includes a motor frame 201, which can fix the position of the motor 202 to prevent the motor 202 from shaking violently during operation. The motor 202 is fixedly connected to the inner wall of the motor frame 201. The bottom output end of the motor 202 is fixedly connected to the drive shaft 203 via a coupling. The outer wall of the drive shaft 203 is fixedly connected to the convex shaft 204. The inner wall of the processing box 1 is slidably connected to a top plate 205. The bottom outer wall of the top plate 205 is fixedly connected to a filter plate 206. Through the filter plate 206, the material can be filtered. Impurities in the filter are filtered and separated and remain on the filter plate 206. The remaining material will pass through the filter plate 206 normally. Several sliding rods 207 are slidably connected to the inner wall of the filter plate 206. Several shock-absorbing springs 208 are fixedly connected to the outer wall of the top plate 205 near the sliding rods 207. A bevel gear 209 is fixedly connected to the outer wall of the drive shaft 203 away from the motor frame 201. An auxiliary mechanism 3 is provided on the outer wall of the processing box 1. The shock-absorbing springs 208 will always pull the top plate 205 tight through their own elastic force, causing the filter plate 206 to fall.

[0030] The outer wall of the motor frame 201 is fixedly connected to the top outer wall of the processing box 1. The outer walls of several slide rods 207 are also fixedly connected to the top outer wall of the processing box 1. The outer walls of several damping springs 208 are also fixedly connected to the top outer wall of the processing box 1. The auxiliary mechanism 3 includes a fixed shaft 301, which can fix the position of the right half gear 308 to prevent the right half gear 308 from disengaging from the meshing state with the rack 307. The outer wall of the fixed shaft 301 is rotatably connected to the top outer wall of the processing box 1. A second fixed shaft 302 is rotatably connected to the top outer wall of the processing box 1 near the fixed shaft 301. The second fixed shaft 302 is located near the bevel gear 209. A bevel gear 303 is fixedly connected to the outer wall of the end. The fixed shaft 302 can fix the position of the bevel gear 303 to prevent it from falling off or even disengaging from the bevel gear 209. The outer wall of the bevel gear 303 meshes with the outer wall of the bevel gear 209. Pulleys 304 are fixedly connected to the outer walls of both the fixed shaft 301 and the fixed shaft 302. A belt 305 is driven to the outer wall of the pulley 304. A slide rail 306 is slidably connected to the inner wall of the processing box 1. The belt 305 can drive the pulley 304, and at the same time, the pulley 304 can limit the belt 305 to prevent it from falling off.

[0031] A rack 307 is fixedly connected to the outer wall of the slide rail 306 near the fixed shaft 301. Half gears 308 are fixedly connected to the outer walls of both the fixed shaft 301 and the second fixed shaft 302. The outer wall of the right half gear 308 meshes with the outer wall of the rack 307. Since multiple half gears 308 mesh with the rack 307, when the multiple half gears 308 rotate in the same direction, they can drive the rack 307 to reciprocate. Several dampers 309 are fixedly connected to the inner wall of the slide rail 306. A scraper 310 is fixedly connected to the bottom outer wall of each damper 309, and the outer wall of the scraper 310 is slidably connected to the inner wall of the slide rail 306. Several damping springs 311 are fixedly connected to the outer wall of the scraper 310 near the damper 309. The scraper 310 can limit the movement trajectory of the damping springs 311 to prevent the damping springs 311 from breaking during the extension and contraction process. The outer walls of the several damping springs 311 are fixedly connected to the inner wall of the slide rail 306. Several through holes 312 are opened on the inner wall of the scraper 310. Several plugs 313 are slidably connected to the inner wall of the end of the processing box 1 away from the top plate 205. The plugs 313 can seal the processing box 1. When the user pulls out the plugs 313, the impurities remaining on the filter plate 206 can be removed.

[0032] One specific application of this embodiment is:

[0033] When the equipment is needed, the motor 202 is started, and then the material is injected into the processing tank 1 through the feeding pipe 101. The filter plate 206 can filter out impurities in the material. The filtered material will pass through the filter plate 206 and fall into the processing tank 1, and be discharged from the discharge pipe 102. When the motor 202 rotates, it can drive the drive shaft 203 to rotate, causing the cam shaft 204 to rotate. The rotation of the cam shaft 204 can push against the top plate 205, causing it to vibrate up and down. When the top plate 205 vibrates up and down, it will cause the filter plate 206 to vibrate up and down and stretch multiple shock-absorbing springs 208. The movement prevents impurities on the filter plate 206 from accumulating in one place, thus reducing the filtration speed of the filter plate 206. The shock-absorbing spring 208 can use its own elastic force to drive the displaced top plate 205 back to its original position, thereby facilitating repeated vibration of the top plate 205. The rotation of the drive shaft 203 drives the bevel gear 209 to rotate, which in turn drives the second bevel gear 303 to rotate, causing the second fixed shaft 302 to rotate. The rotation of the pulley 304 on the second fixed shaft 302 drives the belt 305 to rotate, which in turn drives the pulley 304 on the fixed shaft 301 to rotate, thus... When fixed shaft 301 and fixed shaft 302 rotate in the same direction, they drive half gear 308 to rotate in the same direction. The rotation of half gear 308 drives rack 307 to move. When half gear 308 on fixed shaft 301 just disengages from rack 307, half gear 308 on fixed shaft 302 happens to mesh with rack 307, causing rack 307 to move in the opposite direction. Similarly, when half gear 308 on fixed shaft 302 just disengages from rack 307, half gear 308 on fixed shaft 301 happens to mesh with rack 307. When the rack 307 engages, it can move in the opposite direction again, so the half gear 308 can move in a periodic reciprocating motion. The reciprocating motion of the half gear 308 can drive the slide rail 306 to move in a reciprocating motion. The movement of the slide rail 306 can drive the scraper 310 to move in a reciprocating motion, which can push the impurities remaining on the filter plate 206 towards the position close to the plug 313. The damping spring 311 can squeeze the scraper 310 with its own elastic force to keep it always close to the outer wall of the filter plate 206. After the impurities are removed, the plug 313 can be removed to take out the impurities on the filter plate 206.
