[0002] Wet granulation is a technology that mixes powdered materials with liquid binders to form granules. It is widely used in the pharmaceutical, food and chemical industries.

[0003] In the traditional wet granulation process, the material is made into granules after the processes of batching, adding water, and granulation in the wet granulator. These granules are then discharged through the discharge port of the wet granulator, and then pass through the collection bin and conveyor belt into drying equipment such as fluidized bed or tunnel drying box for drying.

[0004] However, some wet granulation processes result in the granules discharged from the wet granulator outlet having a high water content. The granules are prone to sticking together during transfer to the drying equipment, resulting in incomplete drying or excessive size of the dried granules, affecting the product qualification rate. In addition, the granules are also prone to sticking to the collection silo or conveyor belt and causing blockage, resulting in shutdown for cleaning, which seriously affects production efficiency.

The terms "disposed", "opened", "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, and an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the internal communication of two components.

[0053] See also Figure 1 、 Figure 2 The distributor 2 provided in the embodiment of the present application includes a base 21, a distributor body 22 is connected above the base 21, the distributor body 22 has a feeding channel 221 arranged obliquely from top to bottom, the lower end of the feeding channel 221 is rotatably connected to a scattering roller 23 extending along its width direction, and a raised scattering portion 24 is provided on the outer peripheral surface of the scattering roller 23, and the distributor body 22 is connected to a vibrator 25 located below the feeding channel 221 and a driving mechanism 26 for driving the scattering roller 23 to rotate.

[0054] The distributor 2 provided in the present embodiment is installed between the wet granulator 1 and the drying equipment 3 to transfer the granules discharged from the wet granulator 1 to the drying equipment 3. The base 21 not only serves to mount and support the distributor body 22 but also provides a certain installation height for the distributor body 22. A downwardly inclined feed channel 221 is provided on the distributor body 22 to connect the discharge port of the wet granulator 1 with the feed port of the drying equipment 3, allowing the granules discharged from the wet granulator 1 to flow downward along the feed channel 221 into the drying equipment 3 for drying. The inclined feed channel 221 allows the granules to flow by themselves, eliminating the need for an additional power source to propel the granules, thereby reducing energy consumption and helping to minimize blockage of the granules during flow, reducing the possibility of accumulation and clogging in the feed channel 221. By arranging a scattering roller 23 at the lower end of the feeding channel 221 and arranging a driving mechanism 26 on the distributor body 22, the driving mechanism 26 can be used to drive the scattering roller 23 to rotate, and the scattering roller 23 drives the scattering part 24 thereon to rotate. When the particles flow to the scattering roller 23, the scattering part 24 exerts an impact force on the particles to break up the particles that are stuck together. At the same time, when the particles contact the surface of the scattering roller 23, due to the action of centrifugal force, the particles slide on the surface of the scattering roller 23. This sliding also helps to break up the particles that are stuck together. The broken particles continue to flow downward to the drying equipment 3 for drying. This can reduce the phenomenon of incomplete drying of the particles or excessive size of the particles after drying, thereby improving the product qualification rate. By arranging a vibrator 25 below the feeding channel 221 on the distributor body 22, which is used to generate vibration below the feeding channel 221, it can not only disperse the particles stuck together due to false agglomeration, but also further prevent the particles from sticking to the bottom of the feeding channel 221 and causing blockage, thereby reducing shutdowns for cleaning and improving production efficiency.

[0055] The number of the scattering rollers 23 can be one, two, or more than two, and is not specifically limited here. The more scattering rollers 23 there are, the better the particle scattering effect is, but the larger the installation space occupied is, the higher the cost is. The scattering portion 24 can include a conical scattering tip, and a plurality of scattering tips are evenly distributed on the outer peripheral surface of the scattering roller 23. In some embodiments, see Figure 1 、 Figure 2 、 Figure 3 The scattering portion 24 includes ridges 241 extending axially along the scattering roller 23. Several ridges 241 are evenly distributed along the circumference of the scattering roller 23, and each ridge 241 may have a triangular cross-sectional shape. This structure also enables the scattering of particles to be evenly distributed between adjacent ridges 241, and the particles are transported downward by the rotation of the scattering roller 23.

[0056] The vibrator 25 is a device capable of generating vibrations and may include an electromagnetic vibrator, a pneumatic vibrator, an electric vibrator, or the like. Depending on the length of the feed channel 221, there may be one, two, or more vibrators 25, without specific limitation herein. When there are two or more vibrators 25, the vibrators 25 are spaced apart along the length of the feed channel 221.

[0057] The driving mechanism 26 may include a motor mounted on the distributor body 22, the motor being in transmission connection with the scattering roller 23 to drive the scattering roller 23 to rotate. The transmission mode between the motor and the scattering roller 23 may be chain transmission, gear transmission, belt transmission or direct transmission.

[0058] In some embodiments, see Figure 1 、 Figure 2 The feed channel 221 includes, from top to bottom, a first inclined section 2211 and a second inclined section 2212. The inclination angle of the second inclined section 2212 is greater than the inclination angle of the first inclined section 2211. When particles flow downward in the feed channel 221, they are generally prone to accumulation and blockage in the lower section of the feed channel 221. By setting the inclination angle of the second inclined section 2212 greater than the inclination angle of the first inclined section 2211, the flow velocity of the particles in the second inclined section 2212 is increased, further reducing the possibility of particle accumulation and blockage in the second inclined section 2212.

[0059] To further reduce the possibility of particles accumulating and clogging on the second inclined section 2212, see Figure 2 The width of the second inclined section 2212 increases gradually from top to bottom. This design also helps to clean the particles and is convenient for maintenance personnel to inspect and maintain the feeding channel 221.

[0060] The distributor body 22 can be a tubular structure that is inclined from top to bottom, and the inner cavity of the tubular structure forms a feeding channel 221. In some embodiments, the distributor body 22 can be a trough that is inclined from top to bottom and has a U-shaped cross section. The grooves on the trough form the feeding channel 221. The trough can be made of stainless steel plate; this structure facilitates maintenance personnel to clean and maintain the feeding channel 221. For example, see Figure 1 、 Figure 2 The distributor body 22 includes a distributor base plate 222, which is tilted downward from top to bottom, and two distributor side plates 223 connected above the distributor base plate 222. The base plate 222 and the two distributor side plates 223 define a feed channel 221. The base plate 222 and the two distributor side plates 223 can be welded or integrally molded. The vibrator 25 is located below the second inclined section 2212 and connected to the bottom of the distributor base plate 222.

[0061] In some embodiments, see Figure 1 、 Figure 2 The lower end of the feed channel 221 is provided with a baffle 224 connected to the two distributor side plates 223. A discharge gap 225 is defined between the baffle 224 and the distributor bottom plate 222. The scattering roller 23 is provided on the side of the baffle 224 facing the upper end of the feed channel 221. For example, the two ends of the baffle 224 are respectively welded to the two distributor side plates 223, and the two ends of the scattering roller 23 are rotatably connected to the two distributor side plates 223 via bearings. The baffle 224 is provided to block particles at the lower end of the feed channel 221, allowing the particles to be dispersed by the scattering roller 23 and then enter the drying device 3 through the discharge gap 225. This reduces the probability of particles directly entering the drying device 3 without being dispersed by the scattering roller 23, thereby further improving the product qualification rate.

[0062] The distributor body 22 can be connected to the base 21 through a fixing column. Figure 1 、 Figure 2 The distributor body 22 is connected to the base 21 via a vibration-damping support 27. During operation, the vibrator 25 generates vibrations on the distributor body 22. The vibration-damping support 27 not only supports the distributor body 22 but also deforms in response to external forces, absorbing and reducing the vibration and impact force transmitted downward from the distributor body 22, thereby improving the stability and reliability of the entire device.

[0063] The vibration-damping support 27 may include a plurality of vertically arranged gas struts, the lower ends of which are connected to the base 21, and the upper ends of which are connected to the distributor body 22. A gas strut, also known as a gas spring, is a mechanical component that uses gas pressure to generate elastic force, which can be used to buffer vibrations, thereby achieving a vibration reduction effect.

[0064] In some embodiments, see Figure 4 The vibration-damping support 27 includes a vertically arranged column 271, a spring 272 sleeved on the column 271, and a connecting block 273 arranged above the spring 272 and slidably connected to the column 271; the lower end of the column 271 is connected to the base 21, and the connecting block 273 is connected to the distributor body 22.

[0065] During use, vibrations from the distributor body 22 are transmitted downward to the connecting block 273, which moves downward on the column 271, compressing the spring 272 and generating an elastic force. The elastic force of the spring 272 can be used to buffer the vibrations, thereby achieving a vibration reduction effect. To prevent the connecting block 273 from detaching from the column 271, a stop block 274 is connected to the upper end of the column 271 to limit the position of the connecting block 273.

[0066] The base 21 can be a plate-like structure or a frame structure, as long as it can install and support the distributor body 22. The specific structure is not limited. Figure 1 The base 21 includes a support plate 211 and a support leg 212 connected below the support plate 211. The distributor body 22 is installed above the support plate 211 through a vibration-damping support 27.

[0067] See also Figure 5 The wet granulation apparatus provided in the embodiment of the present application includes a wet granulator 1, a distributor 2, and a drying device 3. The discharge port of the wet granulator 1 is connected to the upper end of the feeding channel 221, and the lower end of the feeding channel 221 is connected to the feed port of the drying device 3. The drying device 3 may include a fluidized bed, a drying oven, etc.

[0068] The working principle of the wet granulation device provided in the embodiment of the present application is as follows: the wet granulator 1, the vibrator 25, the driving mechanism 26 and the drying equipment 3 are started, and the material is formed into granules after undergoing processes such as batching, water addition and granulation in the wet granulator 1. These granules are then discharged through the discharge port of the wet granulator 1 and flow downward through the feeding channel 221. When the granules flow to the scattering roller 23, the scattering roller 23 and the scattering part 24 thereon break up the granules that are stuck together, and the broken up granules then flow into the drying equipment 3 for drying; at the same time, the vibrator 25 generates vibrations below the feeding channel 221 to prevent the granules from sticking to the bottom of the feeding channel 221 and clogging it.

[0069] Therefore, the wet granulation device provided in the embodiment of the present application, by arranging a distributor 2 between the wet granulator 1 and the drying equipment 3, is used to replace the traditional collection box and transmission belt to transport the particles. This can not only reduce the phenomenon of incomplete drying of the particles or excessive size of the particles after drying, thereby improving the product qualification rate, but also reduce shutdowns for cleaning and improve production efficiency.

[0070] The above is only a preferred embodiment of the present application and does not constitute any form of limitation to the present application. Based on the technical essence of the present application and within the spirit and principles of the present application, any simple modification, equivalent replacement and improvement of the above embodiment shall still fall within the scope of protection of the technical solution of the present application.
