Description

Technical Field

[0001] This application relates to the field of dryer material spreading technology, and in particular to a rotating multi-layer material spreading device for a vacuum dryer. Background Technology

[0002] In modern industrial production, many fields such as chemical, food, and pharmaceutical industries have extremely high requirements for the drying of materials. Traditional drying methods have revealed problems such as low efficiency and uneven drying when faced with large-scale and diversified materials.

[0003] The device consists of six major systems, including rotary drive and multi-layer material spreading. During operation, the material is fed through the feed hopper and the distributor to the first layer spreading disc, where it falls as the disc rotates. Hot air flows in a counter-current to dry the material. After drying, the material is discharged through the outlet to the collection hopper. The parameters can be adjusted in a coordinated manner to optimize the process.

[0004] In existing technologies, some dryers have uneven material stacking thickness, resulting in incomplete drying in thicker areas and over-drying in thinner areas, which affects the consistency of finished product quality. The slow heat conduction within the stacked area requires an overall extension of drying time, reducing production efficiency and increasing energy consumption. Localized excessively thick stacking leads to uneven heating of materials, causing them to stick together or even form lumps, affecting subsequent processing or product quality. To address these issues, a rotating multi-layer material spreading device for vacuum dryers is proposed. Utility Model Content

[0005] The purpose of this application is to provide a rotating multi-layer material spreading device for a vacuum dryer, which aims to improve the problems of uneven material accumulation thickness, over-drying, low efficiency, and impact on finished product quality and subsequent processing in existing dryers.

[0013] Through the above technical solution: the vibration mechanism is fixed to the base plate with a fixed plate, and the rotating disk is driven to rotate by the motor and the connecting rod. The rotating disk is slidably connected to the protruding block, and the circular motion is converted into the linear reciprocating motion of the sliding plate.

[0033] The following is in conjunction with the appendix Figure 1 - Appendix Figure 5 This application will be described in further detail below.

[0034] Example: A rotating multi-layer material spreading device for a vacuum dryer, referring to... Figure 1 The dryer 24 includes a base plate 1, with a feeding mechanism 2 fixedly connected to the top of the base plate 1. The base plate 1 ensures the stability of each component during operation and withstands the weight and vibration during the operation of the device. A protective shell 3 is fixedly connected to the top of the feeding mechanism 2. The protective shell 3 serves to protect against external impurities from entering and affecting the material feeding process. Multiple control valves 4 are installed on the left side of the feeding mechanism 2. The control valves 4 ensure the stability and consistency of material processing in the dryer 24 and ensure sealing when no output is required. A container 5 is fixedly connected to the top of the base plate 1. The container 5 ensures continuous operation of the device and allows for adjustment of the material storage volume according to production needs. A filter screen 6 is installed inside the feeding mechanism 2. The filter screen 6 prevents material from entering the dryer 24 and affecting the drying effect, ensuring the purity and drying quality of the material. A funnel 7 is fixedly connected to the top of the feeding mechanism 2. The funnel 7 allows the material to flow more smoothly into the material box 21, reducing material spillage and accumulation. A vibration mechanism 8 is installed on the top of the base plate 1.

[0035] Specifically, the feeding mechanism 2 has an inclined guide plate inside to guide the material to slide down quickly. A sealing strip is added to the seams of the protective shell 3 to prevent dust from entering. The control valve 4 is a pneumatic ball valve, which can precisely adjust the material flow rate. A level gauge is installed on the side of the container 5 for easy observation of the material level. The filter screen 6 has a drawer-type structure, making it easy to remove and clean impurities. The funnel 7 has a large diameter at its wide end and a small end that precisely connects to the material box 21 to ensure smooth material conveying. The vibration mechanism 8 drives the impact plate 874 through an eccentric wheel to periodically impact the material box 21 to prevent material blockage.

[0036] Reference Figure 1 , Figure 2 , Figure 3 The feeding mechanism 2 includes a material box 21, which serves as a temporary storage space for materials, receives materials from the container 5, and provides a material source for the material pump 23. The bottom of the material box 21 is fixedly connected to the top of the base plate 1. A material pipe 22 is fixedly connected to the left side of the material box 21. The material pipe 22 connects the material box 21, the material pump 23, and the dryer 24, conveying materials from the material box 21 to the dryer 24. The material pump 23 is fixedly connected to the left side of the material pipe 22, and another material pipe 22 is fixedly connected to the left side of the material pump 23. The material pump 23 can adjust the conveying pressure and flow rate according to production needs to ensure stable material conveying. The dryer 24 is fixedly connected to the outside of the material pipe 22. The dryer 24 removes moisture and other volatile substances from the materials by heating, vacuuming, etc., to achieve the purpose of drying the materials. Multiple material trays 25 are fixedly connected inside the dryer 24. The surface design and material selection of the material trays 25 ensure that the materials are heated evenly during the drying process. A material spreading assembly 260 is fixedly connected inside the protective shell 3.

[0037] Specifically, in the feeding mechanism 2, the material box 21 is fixed to the top of the base plate 1, temporarily stores the material in the container 5 and supplies the material to the pump 23. The material pipe 22 on its left side connects the pump 23 to the dryer 24 to transport the material. The pump 23 can adjust the pressure and flow rate to ensure stable delivery. The dryer 24 dries the material by heating and vacuuming. The internal material tray 25 ensures uniform heating. The material feeding component 260 inside the protective shell 3 assists in material processing.

[0038] The material spreading assembly 260 includes a motor 261, the drive end of which is fixedly connected to an auger 262. The motor 261 drives the material flow within the spreading pipe 263, and its speed is adjustable. The auger 262 is externally fixedly connected to the spreading pipe 263. The auger 262 uses spiral motion to evenly convey the material to each spreading port 264, ensuring the uniformity of material spreading. Multiple spreading ports 264 are provided inside the spreading pipe 263. These ports are outlets from which material flows out of the spreading pipe 263 and is spread onto the material tray 25. The multiple spreading ports inside the spreading pipe 263... The inlet 264 corresponds to the feeding port 266 on the material tray 25, and the material is evenly spread on the material tray 25. The material tray 25 has multiple feeding ports 266 inside. The size and position of the feeding ports 266 ensure the reasonable distribution of the material on the material tray 25. Multiple spreading plates 265 are fixedly connected to the front side of the spreading pipe 263. After the material flows out from the spreading port 264, the spreading plates 265 help the material to be evenly distributed on the material tray 25 to prevent the material from accumulating. The top of the material tray 25 is slidably connected to the bottom of the spreading plates 265. The top of the bottom plate 1 is fixedly connected to the bottom of the material pump 23.

[0039] Specifically, in the material spreading assembly 260, motor 261 drives auger 262 to rotate inside the material spreading pipe 263. Its rotation speed is adjustable to control material flow. The auger 262, through spiral motion, conveys material through multiple spreading ports 264 within the material spreading pipe 263 to the corresponding feeding ports 266 of the material tray 25, achieving uniform spreading. A spreading plate 265 on the front side of the material spreading pipe 263 assists in material distribution and prevents accumulation. The top of the material tray 25 slides against the bottom of the spreading plate 265, and the base plate 1 supports the material pump 23.

[0040] Reference Figure 4 , Figure 5The vibration mechanism 8 includes a fixed plate 81, which provides a mounting base for the second motor 82, the limiting component 870, etc., ensuring the stability of the vibration mechanism 8 during operation. The bottom of the fixed plate 81 is fixedly connected to the top of the base plate 1. The second motor 82 is fixedly connected to the front side of the fixed plate 81. The second motor 82 converts the rotational motion into the linear reciprocating motion of the sliding plate 86 through mechanical transmission, realizing the vibration of the material box 21. A connecting rod 83 is fixedly connected to the drive end of the second motor 82. The strength and rigidity of the connecting rod 83 ensure the stability and reliability of power transmission. The external of the connecting rod 83 is fixedly connected to... The rotating disk 84, through a sliding connection with the protruding block 85, converts the circular motion into the linear reciprocating motion of the sliding plate 86, providing motion conversion for the vibration mechanism 8. The external side of the rotating disk 84 is slidably connected to the protruding block 85, which converts the circular motion of the rotating disk 84 into its own linear motion, thereby driving the sliding plate 86 to move back and forth to achieve the vibration effect. The front side of the protruding block 85 is fixedly connected to the sliding plate 86, which transmits the motion to the impact plate 874 to achieve impact vibration on the material box 21. The front side of the fixed plate 81 is fixedly connected to the limit component 870.

[0041] Specifically, in the vibration mechanism 8, the fixed plate 81 is fixed to the top of the base plate 1 to provide an installation base for the motor 82, etc. The motor 82 drives the connecting rod 83 and the rotating disk 84. Through the sliding connection with the protruding block 85, the circular motion is converted into the linear reciprocating motion of the sliding plate 86, which drives the impact plate 874 to vibrate the material box 21. The fixed plate 81 is provided with a limiting component 870 on the front side.

[0042] The limiting assembly 870 includes two fixing blocks 871. The fixing blocks 871 ensure the stability and accuracy of the sliding plate 86 during linear reciprocating motion, preventing it from deviating or wobbling. Multiple limiting posts 872 are fixedly connected to the front side of the fixing plates 81. The limiting posts 872 guide and limit the movement of the sliding plate 86, ensuring that the sliding plate 86 moves in a straight line and preventing it from wobbling. Two springs 873 are fixedly connected to the front side of the fixing plates 81. The springs 873 act as buffers and resets during the movement of the sliding plate 86, absorbing vibration energy. The quantity ensures that the sliding plate 86 can reciprocate stably. The front side of the spring 873 is fixedly connected to the rear side of the sliding plate 86. The outer side of the limiting post 872 is slidably connected to the inside of the sliding plate 86. The front side of the sliding plate 86 is fixedly connected to the impact plate 874. The impact plate 874 impacts the material box 21 under the action of the sliding plate 86. The vibration promotes the flow and dispersion of the material in the material box 21. The inner side of the limiting component 870 is rotatably connected to the outside of the connecting rod 83. The front side of the impact plate 874 is in contact with the rear side of the material box 21.

[0043] Specifically, in the limiting assembly 870, two fixing blocks 871 are fixed to the front side of the fixing plate 81, and together with the limiting post 872, they provide guidance and limitation for the sliding plate 86 to ensure its linear movement. Two sets of springs 873 are connected to the rear side of the sliding plate 86 to buffer the impact of movement and assist in resetting. The sliding plate 86 is sleeved on the outside of the limiting post 872 through the internal sliding hole. The front impact plate 874 directly contacts the material box 21 and reciprocates under the action of the sliding plate 86, promoting the flow and dispersion of materials. The entire assembly is rotatably connected to the connecting rod 83.

[0044] The implementation principle of this application embodiment is as follows: The container 5 stores the material to be dried, which flows into the material box 21 of the feeding mechanism 2 through the funnel 7. The filter screen 6 filters impurities. The material pump 23 sends the material to the material tray 25 in the dryer 24 through the material pipe 22. In the material spreading assembly 260, the motor 261 drives the auger 262 to rotate, which drives the material in the spreading pipe 263 to be sent to the material tray 25 through the spreading port 266 and spreading port 264. With the assistance of the spreading plate 265, the material is evenly spread on the material tray 25. After the material is evenly spread, the contact area with the heat source in the dryer 24 is maximized and evenly distributed, which can shorten the overall drying time, avoid local over-drying or under-drying, ensure that each layer of material is dried synchronously, and improve production efficiency and finished product quality stability.

[0045] After motor 82 starts, it drives the rotating disk 84 to rotate through the connecting rod 83. The rotating disk 84 slides with the protruding block 85, converting the circular motion into the linear motion of the protruding block 85. The protruding block 85 drives the sliding plate 86 to perform linear reciprocating motion. The impact plate 874 at the front end of the sliding plate 86 then impacts the material box 21. The limiting post 872 and the fixing block 871 in the limiting component 870 ensure the stability of the sliding plate 86's movement direction. The spring 873 plays a buffering and resetting role, ensuring that the impact plate 874 continuously and stably impacts the material box 21, promoting material flow and dispersion, avoiding local accumulation and overload, ensuring the continuity and stability of the screening process, preventing particles from clogging the screen holes due to static accumulation, ensuring that fine particles can quickly pass through the screen, and increasing the amount of powder screened per unit time.
