Description

Technical Field

[0001] This utility model belongs to the field of chemical preparation technology, and in particular relates to a cutting device for a granulator used in chemical preparation. Background Technology

[0002] The chemical industry involves the production of numerous products, including fertilizers, plastics, rubber, pharmaceuticals, and pigments. Granulation is a crucial step in the production of these products. Granulation can process powdery or lumpy materials into particles with specific shapes and sizes, improving the material's flowability, storage properties, and processing performance to meet the production and application requirements of different chemical products. There are many types of granulators, among which roller granulation is a common one.

[0003] However, the screening efficiency of existing granulators is low, especially in the roller pressing granulation process, where incompletely compacted powder mixes with the formed particles, making it difficult for traditional screening equipment to achieve efficient separation, thus requiring further processing. Utility Model Content

[0004] The purpose of this utility model is to provide a cutting device for a granulator used in chemical preparation. By setting a screening mechanism, it solves the problem that the screening efficiency of the cutting device of the existing granulator is low. Especially in the roller pressing granulation process, the powder that is not fully compacted will mix with the formed particles, making it difficult for traditional screening equipment to achieve efficient separation, thus requiring further processing.

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

[0006] This utility model is a cutting device for a granulator used in chemical preparation, including a rectangular box, on which a screening mechanism and a roller pressing mechanism are provided;

[0007] A plurality of cutting blades are fixedly connected to the inner wall of the rectangular box, and a funnel is fixedly connected to the inner wall of the rectangular box. The screening mechanism includes a screen plate fixedly connected to the inner wall of the rectangular box, and the roller pressing mechanism includes two rotating shafts rotatably connected to the inner wall of the rectangular box. The rear sides of both rotating shafts extend to the outside of the rectangular box, and the front side of the rotating shaft on the right side extends to the outside of the rectangular box. A forming roller is fixedly connected to the outer wall of both rotating shafts.

[0008] Furthermore, a guide plate is fixedly connected to the inner wall of the rectangular box, several L-shaped support plates are fixedly connected to the bottom of the sieve plate, several rectangular support plates are fixedly connected to the inner wall of the rectangular box, and telescopic rods are fixedly connected to the top of each of the rectangular support plates. The tops of the telescopic rods are respectively fixedly connected to the several L-shaped support plates.

[0009] Furthermore, springs are fitted on the outer walls of several of the telescopic rods, the tops of several springs are fixedly connected to several L-shaped support plates, and the bottoms of several springs are fixedly connected to several rectangular support plates.

[0010] Furthermore, a vibration motor is fixedly connected to the bottom of the sieve plate, and discharge ports are provided on both the front and rear sides of the rectangular box. A discharge guide plate is fixedly connected to the rear side of the rectangular box, and the discharge guide plate is adapted to the discharge port located on the rear side.

[0011] Furthermore, two L-shaped fixing plates are fixedly connected to the front side of the rectangular box, and a storage box is slidably connected between the two L-shaped fixing plates.

[0012] Furthermore, a motor is fixedly connected to the front side of the rectangular box, and the output shaft of the motor is fixedly connected to a rotating shaft located on the right side via a coupling. Gears are fixedly connected to the rear extensions of both rotating shafts, and the two gears mesh with each other.

[0013] This utility model has the following beneficial effects:

[0014] 1. By setting up a screening mechanism, when strip-shaped materials fall onto the screen plate, some materials will be dispersed by their own gravity, while others will not be dispersed. At this time, the vibration motor is started. The vibration motor, in cooperation with the telescopic rod and the spring, causes the screen plate to vibrate, which disperses the undispersed materials. The powder on the dispersed materials that has not been rolled into granules will pass through the screen plate and fall onto the guide plate, and then flow out through the discharge guide plate. At this time, these powders are collected and poured back into the rectangular box for rolling. The materials that have been rolled into granules will not pass through the screen plate and will eventually fall into the storage box through the discharge port. This effectively separates the powder that has not been rolled into granules, preventing powder from mixing into the finished granules and reducing the purity of the product. It ensures that only granules that meet the requirements enter the storage box, which greatly improves the product quality.

[0015] 2. By setting up a roller pressing mechanism, when granulation is required, the motor can be started. The motor drives two forming rollers to rotate simultaneously through a shaft and gears. Due to the gears, the two forming rollers rotate in opposite directions, and the outer surface of the forming rollers has grooves. When the material passes through the two forming rollers, it is squeezed into a block shape. This block has many granular protrusions, which continuously draws the material between the rollers and forms grooves on the outer surface of the forming rollers, greatly improving the material processing speed. Moreover, the pressure applied to the material by the opposing forming rollers is more uniform, and the pressure on all parts of the material is consistent, preventing the situation where some materials are poorly formed due to uneven force. This results in uniform density and similar strength of the pressed granules, ensuring the stability of product quality.

[0016] 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

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-5As shown, this utility model is a cutting device for a granulator used in chemical preparation, including a rectangular box 1. A screening mechanism 2 and a roller pressing mechanism 3 are installed on the rectangular box 1. Several cutting blades 101 are fixedly connected to the inner wall of the rectangular box 1, and a funnel 102 is also fixedly connected to the inner wall. The screening mechanism 2 includes a screen plate 211 fixedly connected to the inner wall of the rectangular box 1, a guide plate 212 fixedly connected to the inner wall of the rectangular box 1, several L-shaped support plates 213 fixedly connected to the bottom of the screen plate 211, several rectangular support plates 214 fixedly connected to the inner wall of the rectangular box 1, and telescopic rods 215 fixedly connected to the top of each of the rectangular support plates 214. The tops of the telescopic rods 215 are respectively fixedly connected to the L-shaped support plates 213, and springs 216 are sleeved on the outer walls of the telescopic rods 215. The top of each spring 216 is fixedly connected to several L-shaped support plates 213, and the bottom of each spring 216 is fixedly connected to several rectangular support plates 214. A vibration motor 217 is fixedly connected to the bottom of the sieve plate 211. The front and rear sides of the rectangular box 1 are provided with discharge ports 218. A discharge guide plate 219 is fixedly connected to the rear side of the rectangular box 1. The discharge guide plate 219 is adapted to the discharge port 218 located on the rear side. Two L-shaped fixing plates 220 are fixedly connected to the front side of the rectangular box 1. A storage box 221 is slidably connected between the two L-shaped fixing plates 220. By setting the sieving mechanism 2, the powder that has not been rolled into granules can be effectively separated, avoiding the powder from being mixed into the finished granules and reducing the purity of the product. This ensures that only granules that meet the requirements enter the storage box, greatly improving the product quality.

[0027] The roller pressing mechanism 3 includes two rotating shafts 311 rotatably connected to the inner wall of the rectangular box 1. The rear sides of both rotating shafts 311 extend to the outside of the rectangular box 1, and the front side of the rotating shaft 311 on the right side extends to the outside of the rectangular box 1. A forming roller 312 is fixedly connected to the outer wall of both rotating shafts 311. A motor 313 is fixedly connected to the front side of the rectangular box 1. The output shaft of the motor 313 is fixedly connected to the rotating shaft 311 on the right side through a coupling. Gears 314 are fixedly connected to the rear extensions of both rotating shafts 311. The two gears 314 mesh with each other. By setting up the roller pressing mechanism 3, the material can be continuously rolled into the rollers and formed into the groove on the outer surface of the forming roller 312, which greatly improves the material processing speed. Moreover, the pressure applied to the material by the opposing rotating forming rollers 312 is relatively uniform. The pressure on all parts of the material is consistent, and there will be no situation where some materials are poorly formed due to uneven force. Thus, the pressed particles have uniform density and similar strength, ensuring the stability of product quality.

[0028] A specific application of this embodiment is as follows: In use, the raw material to be granulated is poured into the rectangular box 1 through the funnel 102. Then, the motor 313 is started. The motor 313 drives two forming rollers 312 to rotate simultaneously via the rotating shaft 311 and gear 314. Due to the gear 314, the two forming rollers 312 rotate in opposite directions. The outer surface of the forming rollers 312 has grooves. When the material passes through the two forming rollers 312, it is compressed into a block shape. This block shape has many granular protrusions. The compressed block shape is driven downwards by the two forming rollers 312. When this material encounters the cutting blade 101, it is cut into strips. The material falls onto the screen plate 211. When the strip-shaped material falls onto the screen plate 211, some of the material will be dispersed by its own gravity, while some of the material will not be dispersed. At this time, the vibration motor 217 is started. The vibration motor 217 will cause the screen plate 211 to vibrate under the cooperation of the telescopic rod 215 and the spring 216, which will shake the undispersed material apart. The powder on the dispersed material that has not been rolled into granules will fall onto the guide plate 212 through the screen plate 211 and then flow out through the discharge guide plate 219. At this time, these powders are collected and poured back into the rectangular box 1 for rolling. The material that has been rolled into granules will not pass through the screen plate 211 and will finally fall into the storage box 221 through the discharge port 218.
