Description

Technical Field

[0001] This application relates to the field of granulators, and more particularly to a polyacrylamide spiral granulator. Background Technology

[0002] Polyacrylamide is a linear polymer with high chemical activity. It can be modified to produce various derivatives. Polyacrylamide products are widely used in papermaking, mineral processing, building materials, and other fields. Polyacrylamide granules are a widely used product. In industrial production, the prepared polyacrylamide colloid needs to be granulated into polyacrylamide granules through a granulator, followed by drying and pulverizing processes to form smaller particles for packaging and transportation.

[0003] The existing granulator includes a casing, a motor, a screw conveyor, and a die plate. The casing includes a feed cylinder and a conveying cylinder. The feed cylinder is vertically positioned above the conveying cylinder, while the conveying cylinder is horizontally positioned. The lower end of the feed cylinder is connected to the conveying cylinder. The screw conveyor includes screw blades and a rotating shaft. The screw blades are fixed on the rotating shaft. The screw conveyor is installed in the conveying cylinder and driven by the motor. The die plate is installed on the side of the conveying cylinder away from the motor. The die plate has multiple through holes. When polyacrylamide colloid is poured from the feed cylinder into the conveying cylinder, the motor drives the screw conveyor to rotate, causing the polyacrylamide colloid to move within the conveying cylinder. Finally, the polyacrylamide colloid is extruded from the through holes of the die plate, completing the granulation process.

[0004] The aforementioned technical solutions have the following drawbacks: According to actual processes and production needs, users need to frequently install molds of different shapes on the conveyor cylinder so that polyacrylamide colloid can be extruded from through holes of different sizes to achieve the effect of adjusting the size of polyacrylamide particles. The process of changing the molds is inconvenient and affects work efficiency. Utility Model Content

[0005] To facilitate quick adjustment of the extruded polyacrylamide granules by users, this application provides a polyacrylamide spiral granulator.

[0006] The polyacrylamide spiral granulator provided in this application adopts the following technical solution: A polyacrylamide spiral granulator includes a feed cylinder, a motor, a spiral conveyor, a mold plate, and a conveying cylinder. The conveying cylinder is horizontally arranged, and the feed cylinder is vertically arranged and located above the conveying cylinder. The lower end of the feed cylinder is connected to the conveying cylinder. The spiral conveyor is arranged inside the conveying cylinder. The motor is arranged on one side of the conveying cylinder and drives the spiral conveyor. The mold plate is installed on the end of the conveying cylinder away from the motor. The mold plate includes a fixed plate and a rotating plate. The fixed plate has multiple discharge holes I, and the rotating plate has multiple discharge holes II. The rotating plate and the fixed plate rotate relative to each other. The conveying cylinder is provided with a fixing component that fixes the positions of the rotating plate and the fixed plate.

[0007] By adopting the above technical solution, a feeding cylinder is installed on the conveying cylinder, allowing polyacrylamide colloid to enter the conveying cylinder through the feeding cylinder. A spiral conveying rod is installed in the conveying cylinder, allowing the motor to drive the spiral conveying rod to rotate inside the conveying cylinder, thereby allowing the polyacrylamide colloid to be conveyed along the length of the conveying cylinder. A mold disk is installed at the end of the conveying cylinder, allowing the polyacrylamide colloid to be extruded from the mold disk and form granules. The user can adjust the area of ​​the overlapping region of discharge hole one and discharge hole two by rotating the rotating disk on the fixed disk. When the polyacrylamide colloid is extruded from discharge hole one and discharge hole two, the particle size of the extruded granules can be changed, making it convenient for the user to adjust the particle size of the polyacrylamide granules. After the polyacrylamide granules are extruded, they need to undergo drying and pulverizing processes. Therefore, the roundness of the polyacrylamide granules has little impact on the processing quality. Even if the cross-sectional area of ​​the polyacrylamide granules is elliptical or other irregular shapes when extruded, the granulation effect can still be achieved.

[0008] Optionally, the fixing component is a flange, which is a hollow disc structure. A groove is provided on one end face of the flange, and the rotating disc is set in the groove on the end face of the flange. The fixing disc and the rotating disc are detachably connected to the conveying cylinder through the flange, and the flange and the end face of the conveying cylinder together clamp the fixing disc.

[0009] By adopting the above technical solution, a through hole is opened in the middle of the flange, and a groove is opened on the end face of the flange, so that the rotating disk can be set in the groove. The discharge holes in the middle of the fixed disk and the rotating disk can be exposed through the through hole in the middle of the flange. When the flange is fixed to the conveying cylinder by bolts, the flange and the end of the conveying cylinder clamp the fixed disk. The user can move the rotating disk to adjust the area of ​​the overlapping area of ​​discharge hole one and discharge hole two. When the screw conveyor rotates and conveys polyacrylamide colloid, the polyacrylamide colloid squeezes the fixed disk and the rotating disk. The fixed disk and the rotating disk are supported by the flange and can be stably connected to the end of the conveying cylinder. The fixed disk and the rotating disk are stuck in the groove of the flange, which makes it convenient for the user to replace and clean the mold disk.

[0010] Optionally, the fixing disc is snapped and fixed to the end of the conveying cylinder.

[0011] By adopting the above technical solution, a clamp is set on the fixed plate so that the fixed plate is clamped at the end of the conveying cylinder. When the rotating disk or the threaded conveying rod rotates, the fixed plate can remain stationary relative to the conveying cylinder, thereby keeping the relative position of the fixed plate and the rotating disk stable and keeping the size of the extruded polyacrylamide particles stable.

[0012] Optionally, a retaining element is provided on the end face of the rotating disk, and through holes are provided at both ends of the retaining element. Bolts are provided in the through holes for mounting on the flange or the surface of the rotating disk.

[0013] By adopting the above technical solution, by setting a clamp on the rotating disk, the two ends of the clamp can be fixed to the flange and the rotating disk respectively by bolts, thereby fixing the rotating disk relative to the rotating disk. When the polyacrylamide colloid is extruded from the discharge hole, the rotating disk can remain stationary relative to the fixed disk, thereby keeping the area of ​​the overlapping part of discharge hole one and discharge hole two constant, and keeping the particle size of polyacrylamide particles stable.

[0014] Optionally, the flange end face is provided with multiple threaded holes, which are spaced apart along the circumference of the flange, and the end of the clamp is fixed at different threaded holes by bolts.

[0015] By adopting the above technical solution, multiple threaded holes are opened on the flange, so that the bolts at the end of the clamp can be threaded into different threaded holes. When one end of the clamp is fixed on the rotating disk, by fixing the other end of the clamp into different threaded holes, the area of ​​the overlapping area of ​​discharge hole one and discharge hole two can be adjusted, thereby achieving the effect of adjusting the particle size of the extruded polyacrylamide particles.

[0016] Optionally, the end of the spiral conveyor rod is detachably connected to the fixed disk.

[0017] By adopting the above technical solution, and by connecting the end of the screw conveyor rod to the fixed plate, the end of the screw conveyor rod can be supported by the fixed plate, thus keeping the screw conveyor rod in a stable position inside the conveying cylinder.

[0018] Optionally, a connecting cylinder is provided on the side of the fixed disk away from the rotating disk, and a bearing is provided inside the connecting cylinder. The end of the spiral conveying rod is used to insert into the bearing and rotately connect with the connecting cylinder.

[0019] By adopting the above technical solution, by setting a connecting cylinder on the fixed plate and setting a bearing inside the connecting cylinder, the user can insert the end of the screw conveyor rod into the connecting cylinder, so that the bolt conveyor rod can be connected to the mold plate and rotate on the mold plate.

[0020] Optionally, the number and position of the discharge hole one and discharge hole two correspond one-to-one, and the diameters of discharge hole one and discharge hole two are the same.

[0021] By adopting the above technical solution, when the rotating disk rotates on the fixed disk, the particle size of the extruded particles in each discharge hole is relatively close, resulting in higher processing quality of polyacrylamide granulation.

[0022] In summary, the beneficial technical effects of this application are as follows: 1. By setting a feed cylinder on the conveying cylinder, polyacrylamide colloid can enter the conveying cylinder through the feed cylinder. By setting a screw conveyor rod in the conveying cylinder, the motor can drive the screw conveyor rod to rotate in the conveying cylinder, thereby allowing the polyacrylamide colloid to be conveyed along the length of the conveying cylinder. By setting a mold plate at the end of the conveying cylinder, the polyacrylamide colloid can be extruded from the mold plate to form granules. The user can adjust the area of ​​the overlapping area of ​​discharge hole one and discharge hole two by rotating the rotating disk on the fixed disk. When the polyacrylamide colloid is extruded from discharge hole one and discharge hole two, the particle size of the extruded granules can be changed, which makes it convenient for the user to adjust the particle size of the polyacrylamide granules. 2. By opening a through hole in the middle of the flange and a groove on the end face of the flange, the fixed plate and the rotating plate can be set in the groove. The discharge holes in the middle of the fixed plate and the rotating plate can be exposed through the through hole in the middle of the flange. When the flange is fixed to the conveying cylinder by bolts, both the fixed plate and the rotating plate are installed on the conveying cylinder. The user can move the rotating plate to adjust the area of ​​the overlapping area of ​​discharge hole one and discharge hole two. When the screw conveyor rotates and conveys polyacrylamide colloid, the polyacrylamide colloid squeezes the fixed plate and the rotating plate. The fixed plate and the rotating plate are supported by the flange and can be stably connected to the end of the conveying cylinder. 3. By setting a clamp on the rotating disk, the two ends of the clamp can be fixed to the flange and the rotating disk respectively by bolts, so that the rotating disk can be fixed relative to the rotating disk. When the polyacrylamide colloid is extruded from the discharge hole, the rotating disk can remain stationary relative to the fixed disk, so that the area of ​​the overlapping part of discharge hole one and discharge hole two is constant, and the particle size of polyacrylamide particles remains stable.

[0031] The present application will be further described in detail below with reference to the accompanying drawings.

[0032] This application discloses a polyacrylamide spiral granulator, referring to... Figure 1 and Figure 2 The system includes a feed cylinder 1, a conveying cylinder 2, a motor 3, a spiral conveyor 4, and a mold disk 5. The conveying cylinder 2 is cylindrical, and the feed cylinder 1 is funnel-shaped. The feed cylinder 1 is vertically positioned on top of the conveying cylinder 2, with its lower end connected to the conveying cylinder 2. The spiral conveyor 4 is coaxially mounted inside the conveying cylinder 2. The motor 3 is fixed to one end of the conveying cylinder 2, and its output shaft is connected to the spiral conveyor 4. The mold disk 5 is mounted on the end of the conveying cylinder 2 away from the motor 3. The mold disk 5 has multiple through holes. When polyacrylamide colloid enters the conveying cylinder 2 from the feed cylinder 1, the motor 3 drives the spiral conveyor 4 to rotate. The spiral conveyor 4 pushes the polyacrylamide colloid in the conveying cylinder 2 to one side of the mold disk 5, where it is extruded from the through holes. A collection tray is placed on one side of the mold disk 5 to collect the polyacrylamide granules. The polyacrylamide colloid has a low viscosity; after being extruded from the mold disk 5, it automatically breaks during its descent, forming long granules and achieving the granulation effect. After polyacrylamide granules are extruded, they need to be dried and pulverized. Therefore, the roundness of polyacrylamide granules has little impact on processing quality. Even if the cross-sectional area of ​​the polyacrylamide granules is elliptical or other irregular shapes when extruded, granulation effect can still be achieved.

[0033] Reference Figure 3 and Figure 4 The mold disk 5 includes a fixed disk 51 and a rotating disk 52. The fixed disk 51 is detachably connected to the end of the conveying cylinder 2. The rotating disk 52 is rotatably connected to the fixed disk 51 and coaxially arranged with the fixed disk 51. The fixed disk 51 has multiple discharge holes 510, which are arranged at equal intervals along the circumference of the fixed disk 51. The rotating disk 52 has multiple discharge holes 520, which are the same size and correspond to each other in position. By rotating the rotating disk 52, the user can adjust the position of the discharge holes 510 relative to the discharge holes 520, thereby allowing the polyacrylamide colloid to be extruded through the common space of the discharge holes 510 and the discharge holes 520, making it convenient for the user to adjust the particle size of the extruded polyacrylamide particles.

[0034] Reference Figure 6 and Figure 7 A flange 511 is connected to the fixed plate 51. The flange 511 is used for detachable connection to the end of the conveying cylinder 2. The flange 511 has a hollow disc structure, and a groove is opened on one end face of the flange 511. The fixed plate 51 and the rotating plate 52 are fitted together and embedded in the groove of the flange 511. When the flange 511 is installed on the conveying cylinder 2, the fixed plate 51 and the rotating plate 52 are locked in the groove of the flange 511, so that the fixed plate 51 is installed on the conveying cylinder 2, and the rotating plate 52 can rotate relative to the fixed plate 51. The user can remove and clean the mold plate 5 through the flange 511. To reduce the probability of the fixed plate 51 rotating at the end of the conveying cylinder 2, a flange can be set on the outside of the fixed plate 51, so that the flange 511 fits against the flange of the fixed plate 51 and is connected to the flange on the end face of the conveying cylinder 2, thereby fixing the fixed plate 51 to the end face of the conveying cylinder 2.

[0035] Reference Figure 4 and Figure 5 A clamping element 522 is installed on the end face of the rotating disk 52 away from the fixed disk 51. The clamping element 522 has a rod-shaped structure with through holes at both ends. Bolts are installed at both ends of the clamping element 522 for threaded connection to the rotating disk 52 or the flange 511. When the two ends of the clamping element 522 are connected to the rotating disk 52 and the flange 511 respectively, the length direction of the clamping element 522 points towards the center of the rotating disk 52. When the user clamps the clamping element 522 between the flange 511 and the rotating disk 52, the rotating disk 52 can be fixed relative to the fixed disk 51, thereby keeping the particle size of the polyacrylamide colloid stable during extrusion. The flange 511 has multiple threaded holes. By installing the bolts at the end of the clamping element 522 into the threaded holes at different positions, the user can adjust the position of the rotating disk 52 relative to the fixed disk 51, and thus adjust the position of the discharge hole 1 510 relative to the discharge hole 2 520, thereby adjusting the particle size of the extruded particles.

[0036] Reference Figure 3 A connecting cylinder 515 is provided on the end face of the fixed disk 51 away from the rotating disk 52. A bearing is installed inside the connecting cylinder 515, and the inner ring of the bearing is used to connect with the end of the screw conveyor 4. When the mold disk 5 is installed on the conveying cylinder 2, the end of the screw conveyor 4 is inserted into the bearing in the connecting cylinder 515, thereby making the screw conveyor 4 rotatably connected to the mold disk 5, so that the screw conveyor 4 can rotate stably inside the conveying cylinder 2.

[0037] The implementation principle of this application embodiment is as follows: By setting a spiral conveying rod 4 inside the conveying cylinder 2, when the polyacrylamide colloid enters the conveying cylinder 2 from the feeding cylinder 1, the motor 3 drives the spiral conveying rod 4 to rotate, thereby conveying the polyacrylamide colloid to the end of the conveying cylinder 2 and extruding it from the mold plate 5. By rotating the rotating plate 52 on the fixed plate 51, the user can adjust the area of ​​the overlapping part of the discharge hole 1 510 and the discharge hole 2 520 by adjusting the position of the rotating plate 52, thereby achieving the effect of adjusting the particle size of the extruded polyacrylamide particles.

[0038] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
