Description

Technical Field

[0001] This utility model relates to the field of material transfer technology, and in particular to a feeding device for preventing material sticking. Background Technology

[0002] In the industrial production of inorganic crystalline materials such as sodium chlorate and potassium perchlorate, the problem of material adhesion during the crystallization feeding process has long plagued production continuity and equipment stability. Although these materials themselves do not have inherent viscosity, during the feeding process after crystallization and separation, due to the combined influence of multiple factors, crystals are prone to sticking together or adhering to the equipment surface. Specifically, a small amount of mother liquor containing solute often remains on the surface of the crystals after crystallization. When the ambient temperature fluctuates, humidity increases, or the material stays in the equipment for too long during the feeding process, the evaporation of water in the residual mother liquor can trigger secondary crystallization, causing fine crystals to connect with each other in the form of "crystal bridges" and form lumpy agglomerates. At the same time, if the crystallization process is not properly controlled (such as excessively fast cooling rate or uneven stirring), a large number of ultrafine crystals will be produced, and the strong adsorption force brought about by their high specific surface area will further aggravate the adhesion between particles.

[0003] In actual production, this adhesion phenomenon mainly manifests as follows: a layer of scale forms on the inner wall of the feeding pipe, resulting in a reduction in the flow cross-section and an increase in resistance, which can lead to pipe blockage in severe cases; material accumulates at the corners or sealing surfaces of equipment such as hoppers and valves, which not only affects the feeding accuracy but also forms stubborn scale due to continuous adhesion, increasing the frequency of equipment cleaning and maintenance costs; for conveying equipment such as screw conveyors and vibrating feeders, the adhered material will adhere to the blades or conveying surface, reducing the conveying efficiency and even causing fluctuations in the feeding of subsequent processes due to uneven feeding.

[0004] Patent CN214165996U, "Anti-clogging Silo," discloses an anti-clogging silo. This silo features a top-mounted filter screen, including inclined grates and horizontal grates. Electric vibrators are installed on the non-working parts of the grates to address the issue of material overflowing from the top. A high-polymer PE board is fixed to the inner surface of the silo body to prevent wet material from adhering to the inner wall. Vibrators are installed on one side and the opposite side of the discharge port to address the issue of material not discharging from the bottom of the silo. A material cut-off device is installed below the vertical side of the discharge port, electrically connected to the vibrators, to detect the material's descent. However, this patented technology primarily addresses the clogging problems caused by wet materials and large pieces of material in the cement industry, and its structure and function have industry limitations. The way the vibrators and material cut-off devices are configured cannot directly adapt to the high precision and high cleanliness requirements of the feeding device for inorganic crystalline materials such as sodium chlorate and potassium perchlorate. Regarding the issue of material adhesion and accumulation, the silo's anti-clogging effect is limited for highly viscous materials with stringent hygiene requirements, making it difficult to meet production needs.

Unless otherwise specified, embodiments of the present invention and the various features thereof can be combined with each other, all within the protection scope of the present invention. Example

[0020] Please see Figure 1This utility model provides a feeding device to prevent material adhesion. Inorganic crystalline materials such as sodium chlorate and potassium perchlorate generally have high viscosity or hygroscopicity. During the feeding process, they are prone to adhesion to the inner wall of the hopper, the joint between the upper and lower hoppers, and the discharge port due to intermolecular forces, electrostatic adsorption, or humidity, leading to poor feeding, blockage, and even contamination of the material (the residual material deteriorates and mixes with the new material). The feeding device to prevent material adhesion of this application uses a vibration component to make the first hopper 240 shake, a stirring mechanism to disperse the material, a flexible transition joint 250 to reduce retention at the connection points, and a spiral discharge mechanism to ensure stable conveying. It can specifically solve the adhesion problem during drug feeding and meets the stringent requirements of the pharmaceutical industry for equipment cleanliness (such as the material of contact parts and sealing structure) and feeding accuracy. Therefore, it is suitable for drug feeding scenarios. Please see Figure 1 and Figure 2 In this embodiment, the drug anti-adhesion feeding device includes a mounting frame 100 and a hopper with a vibration assembly disposed on the mounting frame 100; the hopper includes a first hopper 240 and a second hopper 260 connected by a flexible transition joint 250, the first hopper 240 having a first inlet 241 at its top, and the second hopper 260 having a first outlet 261 at its bottom; the mounting frame 100 has a mounting plate 110 at its top, and the mounting plate 110 has a mounting through hole 111 for the first hopper 240; the vibration assembly... The system includes a first vibration ring 211 and a second vibration ring 212 fixed to the outside of the first hopper 240. A motor mounting plate 221 is provided through the first vibration ring 211 and the second vibration ring 212, and a vibration motor 222 is provided on the motor mounting plate 221. The vibration assembly also includes a plurality of elastic supports 230 disposed on the outer ring of the mounting through hole 111. The two ends of the elastic supports 230 are respectively connected to the first hopper 240 and the mounting plate 110, so that the first hopper 240 can be oscillating and discharging materials based on the elastic supports 230. In operation, the vibration motor 222 is started first. After the vibration motor 222 starts, the driving force is transmitted through the motor mounting plate 221 to the first vibration coil 211 and the second vibration coil 212, thereby driving the first hopper 240 to vibrate. Since the first hopper 240 is connected to the mounting plate 110 through the elastic support 230, the vibration spring 233 in the elastic support 230 will undergo elastic deformation with vibration, so that the first hopper 240 can achieve controllable shaking in the mounting through hole 111 of the mounting frame 100. This shaking is transmitted to the material in the hopper, causing the material to continuously change its contact state with the hopper wall during the falling process, reducing the chance of continuous adhesion, and moving towards the flexible transition section 250 under the action of gravity, and finally entering the second hopper 260 to complete the unloading. Furthermore, in this embodiment, the first hopper 240 is used for material feeding via a shaking motion. The shaking of the first hopper 240 can disrupt the stable adhesive layer formed between the material and the hopper wall. This is particularly effective for highly viscous traditional Chinese medicine extracts and high-moisture granules in pharmaceuticals, preventing large amounts of material from remaining on the hopper wall and reducing the risk of contamination. The kinetic energy generated by the shaking helps the material overcome its own viscosity, accelerates its falling speed, reduces its residence time in the first hopper 240, and ensures the continuity of material feeding. Furthermore, the swaying feeding mechanism matches the flexibility of the flexible transition joint 250. The flexible transition joint 250 can adapt to the swaying of the first hopper 240, preventing material accumulation at the connection point due to rigid fixation and ensuring smooth material entry into the second hopper 260. The guiding effect of the elastic support 230 keeps the swaying of the first hopper 240 within a controllable range, preventing material splashing due to excessive swaying amplitude, and ensuring uniform material drop through continuous vibration and oscillation. This lays the foundation for stable conveying by the subsequent screw discharge mechanism and meets the material feeding accuracy requirements of pharmaceutical production. Furthermore, the flexible transition section 250 adopts an annular sleeve type configuration, including an inner sealing body, a middle reinforcing skeleton, and an outer protective sleeve; the middle reinforcing skeleton is a stainless steel corrugated pipe or a polytetrafluoroethylene woven mesh, and the outer protective sleeve is made of polyurethane elastomer; the two ends of the flexible transition section 250 are sealed and connected to the connecting flanges of the first hopper 240 and the second hopper 260 through flanged flanges. The inner sealing layer of the flexible transition joint 250 provides excellent sealing performance, effectively preventing material leakage during the transition process and ensuring hygiene and safety in the pharmaceutical production process. The middle reinforcing skeleton, whether made of stainless steel corrugated pipe or PTFE woven mesh, possesses excellent flexibility and strength, adapting to deformation caused by the shaking of the first hopper 240 while ensuring the flexible transition joint 250 is not easily damaged during long-term use, thus extending its service life. The outer protective sleeve, made of polyurethane elastomer, not only possesses wear-resistant and aging-resistant properties but also protects the middle reinforcing skeleton, reducing external erosion. Simultaneously, the flexible transition joint 250 is sealed to the connecting flanges of the first hopper 240 and the second hopper 260 at both ends via flanged flanges. This connection method is convenient to install and provides a reliable seal, further ensuring the smoothness and sealing of material transition between the two hoppers. It avoids material blockage or leakage problems that may occur due to loose connections, providing strong support for the efficient and stable operation of the entire pharmaceutical production process. Moreover, this annular sleeve-type flexible transition joint 250 has a compact structure and occupies little space, which is conducive to the rational layout of equipment in limited production space, improving space utilization. It also facilitates daily maintenance and repair work, reducing equipment maintenance costs and improving the overall efficiency of pharmaceutical production. Further, please see Figure 2 and Figure 4 The flexible transition joint 250 serves to flexibly connect the first hopper 240 and the second hopper 260, ensuring the airtightness of the connection to prevent leakage of pharmaceutical materials. It can also adapt to the shaking of the first hopper 240, preventing gaps or damage to the connection due to the shaking of the first hopper 240. At the same time, it reduces the accumulation of materials at the connection, ensuring that materials can smoothly enter the second hopper 260 from the first hopper 240. Together with the shaking discharge, it ensures the stability and efficiency of the entire discharge process. Furthermore, the elastic support 230 includes a guide rod 231 and a sleeve 232 sleeved on the guide rod 231. The guide rod 231 is disposed on the mounting plate 110, and the sleeve 232 is disposed on the first hopper 240. The sleeve 232 is also provided with a vibration spring 233 at both ends connected to the mounting plate 110 and the first hopper 240 respectively. When the vibratory motor 222 drives the first hopper 240 to shake, the sleeve 232 fixed to the first hopper 240 moves with the hopper. The sleeve 232, fitted onto the guide rod 231, slides back and forth along the guide rod 231 within a small range. At the same time, the vibration spring 233 undergoes tensile or compressive deformation between the mounting plate 110 and the first hopper 240, providing elastic support and restoring force for the hopper's shaking. The cooperation between the guide rod 231 and the sleeve 232 restricts the direction of the hopper's shaking, preventing it from shifting randomly. The vibration spring 233 absorbs and transmits vibration energy through elastic deformation, keeping the hopper's shaking within a stable and controllable range. The guiding cooperation between the guide rod 231 and the sleeve 232 ensures the directionality of the hopper's shaking, preventing material splashing or equipment damage due to excessive shaking amplitude or disordered direction, thus meeting the stability requirements of pharmaceutical production. The elastic support of the vibration spring 233 provides sufficient shaking space for the hopper to break material adhesion, and can also quickly restore the hopper to balance through its own restoring force, ensuring the continuity and regularity of the shaking. At the same time, the overall structure is simple and the components are highly coordinated, making it easy to maintain and clean, meeting the cleanliness standards of pharmaceutical equipment, and can be used with vibration components, flexible transition joints 250, etc., to form an efficient anti-adhesion feeding system. Further, please see Figure 2 and Figure 3 The first hopper 240 is also equipped with a stirring mechanism through a sealing plate 310. The sealing plate 310 and the side wall of the first hopper 240 form the first feed inlet 241. The stirring mechanism includes a stirring motor 320 and a stirring shaft 360 arranged through a rotating seat 330 on the sealing plate 310. The stirring shaft 360 is provided with a plurality of stirring blades 340. Furthermore, the sealing plate 310 is also provided with a door for opening or closing the first feed port 241 via a hinge. Furthermore, the stirring shaft 360 is provided with a plurality of stirring rods 350, which are spaced apart in both the circumferential and axial directions of the stirring shaft 360, and the stirring blades 340 are disposed on the stirring rods 350. Furthermore, the stirring blade 340 includes a connecting piece 341 and a stirring blade 342 that is bent to the connecting piece 341. The stirring blade 340 is connected to the stirring rod 350 through the connecting piece 341.

[0021] In use, the stirring motor 320 is started. After the stirring motor 320 starts, it drives the stirring shaft 360 to rotate through the rotating seat 330 on the sealing plate 310. The stirring rod 350 on the stirring shaft 360 rotates with the shaft, thereby driving the stirring blades 340 installed on the stirring rod 350 to move synchronously. The connecting piece 341 of the stirring blades 340 is fixed to the stirring rod 350. When the bent stirring blades 342 rotate, they will shear and push the material in the first hopper 240, breaking up the lumps or sticky materials. At the same time, the first feed port 241 formed by the sealing plate 310 and the side wall of the first hopper 240 can be opened or closed through the hopper door (controlled by a hinge). After the material enters from the feed port, it moves to the lower part of the hopper under the continuous stirring of the stirring blades 340, and the shaking of the first hopper 240 helps to disperse the material. Specifically, the bent stirring blades 342 of the stirring blades 340 increase the contact area with the material, efficiently dispersing easily agglomerated powders or particles in the medicine, avoiding material blockage caused by agglomeration, and enhancing the anti-sticking effect in conjunction with the shaking feeding method. The silo door can be flexibly opened and closed through the first feed port 241 via a hinge, facilitating control of the feed rate to meet the feeding requirements of different batches of medicines. At the same time, closing the silo door when the machine is stopped can prevent material residue from leaking out. The stirring rods 350 are distributed circumferentially and axially on the stirring shaft 360. Combined with the three-dimensional layout of the stirring blades 340, they can cover most of the space within the first hopper 240, reducing localized material accumulation within the hopper, and are particularly suitable for the uniform dispersion of viscous pharmaceuticals. The stirring blades 340 are connected to the stirring rods 350 via connecting pieces 341, making disassembly and assembly convenient for cleaning or replacement. Further, please see Figure 1 and Figure 2The bottom of the second hopper 260 is also provided with a spiral discharge mechanism connected to the first discharge port 261; the spiral discharge mechanism includes a first rotating seat 411 and a second rotating seat 412 disposed at both ends of the frame, and a material cylinder 420 disposed between the first rotating seat 411 and the second rotating seat 412; the material cylinder 420 is provided with a discharge screw 430 that rotates based on the first rotating seat 411 and the second rotating seat 412; the two ends of the material cylinder 420 are respectively provided with a second inlet 441 and a second outlet 442. Furthermore, the second feed inlet 441 is connected to the first discharge outlet 261. Furthermore, one end of the material cylinder 420 is also provided with a discharge motor 450, which is connected to the first rotating seat 411 or the second rotating seat 412 in a transmission connection. In use, the discharge motor 450 is started first. After starting, the discharge motor 450 drives the discharge screw 430 in the material cylinder 420 to rotate under the support of the first rotating seat 411 and the second rotating seat 412 through the transmission connection with the first rotating seat 411 or the second rotating seat 412. The material discharged from the first discharge port 261 of the second hopper 260 enters the material cylinder 420 through the connected second inlet 441. Under the pushing action of the spiral blades of the discharge screw 430, it moves along the inner wall of the material cylinder 420 towards the second discharge port 442, ultimately achieving continuous and stable discharge. In this embodiment, by adjusting the rotational speed of the discharge motor 450, the pushing speed of the discharge screw 430 can be precisely controlled, thereby achieving precise control over the amount of medicine discharged and meeting the strict requirements for material metering in pharmaceutical production. The continuous rotation of the discharge screw 430 generates a continuous thrust on the material entering the barrel 420, effectively preventing viscous medicine from clogging inside the barrel 420 and at the second discharge port 442, ensuring smooth material discharge. Furthermore, the screw discharge mechanism can achieve stable conveying of pharmaceutical materials with different viscosities and particle sizes through the pushing action of the screw, enhancing the versatility of the device for pharmaceutical feeding. The first rotating seat 411 and the second rotating seat 412 provide stable support for the discharge screw 430, ensuring its coaxiality during rotation, reducing vibration and noise. At the same time, the closed structure of the barrel 420 can prevent the material from being contaminated during the conveying process, meeting the cleanliness requirements of pharmaceutical production.
