Description

Technical Field

[0001] This utility model relates to the field of material transfer technology, specifically a glycine transfer device. Background Technology

[0002] In the industrial production process of glycine, traditional centrifuge unloading technology mainly relies on a rotating scraper to scrape the material onto the discharge port. Utilizing gravity, the material is discharged from the bottom of the filter bag by its own weight after the equipment stops. While this method is simple to operate, it has low unloading efficiency. Material adhesion or residue can lead to incomplete unloading, and measuring moisture content after the wet product is discharged increases operation time. During material transfer, on-site personnel need to use transfer bags to receive the material. Furthermore, methanol volatilization in the finished product increases fugitive emissions, raises safety risks, and deteriorates the operating environment. Manual operation of hydraulic pallet trucks is required to transport the transfer bags to the drying and feeding system, and electric hoists are used to lift each bag to the drying feed hopper. The entire unloading and transfer process is open, easily introducing particulate matter and flying insects, causing quality accidents. This process is time-consuming and labor-intensive, significantly increasing labor costs and reducing production efficiency. To solve these problems, a closed continuous conveying and transfer system integrating online moisture detection and automatic speed adjustment is urgently needed on the production site. Utility Model Content

[0005] Furthermore, the material inlet of the hopper is flexibly connected to the centrifuge; the material outlet is equipped with a gate valve.

[0006] Furthermore, the hopper is equipped with a nitrogen inlet and several samplers.

[0007] Furthermore, the hopper is provided with an observation window, and a scraper is provided on the observation window.

[0030] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0031] Specific implementation method one: See Figures 1-6 This embodiment describes a glycine transfer device comprising several hoppers 1, several screw conveyors 2, a tubular chain conveyor 3, and a drying silo 4. The material inlet of each hopper 1 is connected to a centrifuge via a flexible connection, effectively isolating the hopper 1 from the adverse effects of centrifuge vibrations. The material outlet of each hopper 1 is connected to the screw conveyors 2, and a gate valve 6 is installed at the material outlet for quick disassembly and repair in case of screw conveyor 2 malfunction, minimizing material loss. The screw conveyors 2 are connected to the tubular chain conveyors 3, and the outlet of the lower tube of the tubular chain conveyor 3 is located above the drying silo 4 and is equipped with a knocking and clearing mechanism 13. The return port at the end of the upper tube of the chain conveyor 3 is equipped with a jet cleaning mechanism 12 and a knocking cleaning mechanism 13. The jet cleaning mechanism 12 uses jetted gas to clean the material accumulated on the material tray and uses a throttle valve to regulate the flow rate to reduce gas waste. The knocking cleaning mechanism 13 includes a spring 14 and a knocking rod 15. One end of the spring 14 is connected to the inner wall of the return port, and the other end is connected to the middle of the knocking rod 15. One end of the knocking rod 15 is rotatably connected to the inner wall of the return port of the tubular chain conveyor 3. Under the pushing action of the material tray, the movable end of the knocking rod 15 swings in the direction of the material tray movement. At the same time, the spring 14 is pulled open. After the movable end of the knocking rod 15 separates from the material tray, it swings back under the action of the spring 14 to knock on the next material tray.

[0032] The hopper 1 is equipped with a nitrogen inlet 8 and several samplers 7. The samplers 7 are used to check the qualification of the material, and nitrogen is introduced into the hopper 1 through the nitrogen inlet 8 to form a nitrogen seal.

[0033] The hopper 1 is provided with an observation window 5, and a scraper is provided on the observation window 5.

[0034] The screw conveyor 2 is equipped with an upper discharge port, a feed port, and a lower discharge port. The feed port is located in the middle area of ​​the screw conveyor 2 and opens upwards, connecting to the material outlet of the hopper 1 for easy unloading of materials from below the hopper 1. Both the upper and lower discharge ports open downwards, with the lower discharge port connecting to the lower pipe of the tubular chain conveyor 3. The lower discharge port is used to convey qualified materials, while the upper discharge port is used to discharge unqualified materials. The screw conveyor 2 adopts an inclined design, placing the lower discharge port on the lower side for easy connection to the tubular chain conveyor 3, while the upper discharge port is located on the higher side, allowing for the placement of ton bags below. The lower discharge port is equipped with a gate valve 6 for isolation when the equipment is idle or under maintenance. The upper discharge port is mainly used for abnormal operating conditions; therefore, a quick-release cover plate 9 is added at this port to ensure on-site safety standardization and reduce nitrogen loss. The screw conveyor 2 can operate in both directions, effectively conveying both qualified and unqualified materials.

[0035] The tubular chain conveyor 3 is equipped with several observation holes 11 and several maintenance ports. The observation holes 11 are made of glass and equipped with scrapers. The condition inside the pipe can be observed through the observation holes 11. The maintenance ports make it easier to replace damaged or aging feed discs and scraper discs, as well as to clean the inner wall of the pipe.

[0036] The tubular chain conveyor 3 is equipped with a nitrogen filling port 16, and nitrogen gas is used for protection during the material conveying process.

[0037] The chain and material tray inside the tubular chain conveyor 3 are detachably connected by a snap fastener for easy replacement. The material tray has multiple connection points to ensure that it runs perpendicular to the pipeline.

[0038] The material tray includes a feeding tray 10 and a scraper tray. The diameter of the feeding tray 10 is smaller than the diameter of the tubular chain conveyor 3, which ensures the strength of the feeding tray 10 while eliminating direct friction between metals. The edge of the scraper tray is made of flexible material and is not easy to wear off. It contacts the tube wall of the tubular chain conveyor 3 to ensure cleaning capacity while reducing unnecessary energy consumption.

[0039] The glycine transfer device described in this embodiment is also equipped with a PLC control system and control cabinet. The control system can realize control functions such as opening and closing of various pneumatic valves, starting and stopping of the screw conveyor 2 and its forward and reverse rotation, starting and stopping of the tubular chain conveyor 3 and speed adjustment. The control system can realize automatic operation control such as nitrogen sealing, nitrogen purging, and air hammer operation, and can also realize manual connection, displaying the operating status of each component on the control panel.

[0040] The specific working process of the glycine transfer device described in this utility model is explained as follows:

[0041] Hopper 1 is connected to the centrifuge outlet, and the bottom of hopper 1 is connected to screw conveyor 2. A sampler 7 at the bottom of hopper 1 is used to inspect the material's quality. For qualified material, screw conveyor 2 rotates forward, connecting hopper 1 to the lower pipe channel of tubular chain conveyor 3 for unloading. The material is then conveyed to drying silo 4 via tubular chain conveyor 3. Conversely, screw conveyor 2 rotates backward, discharging unqualified material through the screw and conveying it to the unqualified material bag. A high-pressure air jet cleaning mechanism and a knocking cleaning mechanism are installed at the return port at the upper end of the tubular chain conveyor 3 to clean the material adhering to the trays, minimizing the entry of material into the tail section. Throughout the process, the tubular chain conveyor operates in a uniform direction, ensuring uninterrupted normal operation. A nitrogen filling port 16 is provided for continuous nitrogen protection. A sampler 7 is installed at the bottom of hopper 1 for dynamic sampling to determine material quality. An observation window 5 is provided to observe the material emptying status of hopper 1, allowing for on-site control of screw conveyor 2 and switching of material transport.

[0042] In summary, the glycine transfer device of this utility model uses a sampler 7 to detect whether the material is qualified. For materials that meet the quality standards, the screw conveyor 2 can be directly connected to the tubular chain conveyor 3 to achieve fully automated continuous conveying. For unqualified materials, the screw is quickly discharged by reversing the spiral to ensure the smooth operation of the main production line. The observation window 5 and manual scraper of the hopper 1 facilitate real-time monitoring and cleaning. Flexible connection vibration isolation technology is used to extend the service life of the equipment and improve sealing performance. A manual gate valve 6 is installed at the material outlet of the hopper 1 for emergency maintenance and leakage prevention.

[0043] This utility model discloses a glycine transfer device. The tubular chain conveyor 3 is equipped with a glass observation port 11 to improve fault diagnosis efficiency. It features segmented maintenance ports and detachable chains and trays to shorten the time required for single-point maintenance. A throttling valve enables precise control of the purging flow rate of the jet cleaning mechanism, thereby reducing operating costs. This device reduces manual handling costs and monitoring requirements, shortens transfer time, optimizes the production process, and improves efficiency. Simultaneously, the tubular chain conveyor 3 reduces the volatilization of semi-finished methanol, and nitrogen is introduced through the nitrogen filling port for full nitrogen protection, reducing safety risks such as fire and explosion, improving environmental friendliness and safety, reducing raw material waste, and increasing product yield.

[0044] The glycine transfer device described in this utility model allows for direct modification and adjustment of parameters via the touchscreen of the PLC control system, thereby effectively shortening the time required for process switching. At the same time, the automatic location of faults through the PLC control system significantly reduces the time required for maintenance.

It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit the utility model. They can also be reasonable combinations of the features described in the above embodiments.
