Description

Technical Field

[0001] This invention relates to the technical field of novel solvent-based cellulose preparation, specifically to an intelligent automated feeding and discharging system suitable for cellulose. Background Technology

[0002] With the progress of the times, our industry has entered an era of automation and intelligence. From a global perspective, industrial automation manufacturing is an emerging direction that will benefit from future development, with obvious advantages such as improving production efficiency, reducing costs, saving manpower, and promoting industrial upgrading.

[0003] Given the unique characteristics of the new solvent-based continuous cellulose production process, higher demands are placed on the safety performance of the equipment—making the automation and intelligence of daily maintenance, repair, and cleaning of the equipment even more crucial. Currently available cellulose feeding and discharging systems suffer from low levels of automation, difficulty in cleaning and maintenance, and potential safety hazards. These systems fail to meet the requirements of automated production, customer and market demands, and the national strategic goals of green, low-carbon, and sustainable development. Summary of the Invention

[0004] The purpose of this invention is to solve the aforementioned technical problems by proposing an intelligent automated feeding and discharging system suitable for cellulose. This invention enables flexible switching between working and auxiliary stations, facilitating intelligent and automatic transitions between normal production states and abnormal production states such as process debugging, maintenance, or cleaning. It also enables intelligent and automatic cleaning of the cellulose feeding and discharging system, providing a guarantee for achieving unmanned and green workshops.

[0005] The objective of this invention can be achieved through the following measures:

[0006] This invention provides an intelligent automated feeding and discharging system for cellulose, comprising a variable-diameter feed channel and a main discharge channel connected vertically by bolts; a discharge chute assembly with a side opening located on the upper side of the main discharge channel at its upper end and mounted on support legs at its lower end, connected to an external storage system; an automatic baffle valve assembly installed in the inner cavity of the main discharge channel, switching between a working position blocking the side opening and an auxiliary position blocking the discharge port by flipping; an intelligent cleaning mechanism surrounding the main discharge channel; and a DCS control system (this invention is designed with two material channels—automatic during normal production). When the baffle valve assembly is in the working position, the material enters the subsequent main equipment along the vertically connected variable diameter feeding channel and the main discharge channel; when in abnormal production conditions, the automatic baffle valve assembly is in the auxiliary position, and the material enters the external storage system along the variable diameter feeding channel, the baffle in the automatic baffle valve assembly, and the discharge chute assembly. This invention, through the linkage control of the DCS control system, enables the automatic flipping of the automatic baffle valve assembly to achieve flexible switching between the working position and the auxiliary position, meeting the intelligent automatic conversion between normal production conditions and abnormal production conditions such as process debugging, maintenance, or cleaning. This invention, through linkage with the intelligent cleaning mechanism (4), The opening and closing mechanism enables intelligent automatic cleaning, providing a guarantee for the realization of unmanned and green workshops. The main material discharge channel is welded from a variable diameter discharge section and a straight discharge section (as part of the material channel). Connecting flange II is provided at the upper end of the variable diameter discharge section and the lower end of the straight discharge section (for easy installation or disassembly). A valve cylinder mounting seat is installed on the left side of the straight discharge section (as the mounting base for the pressure reducing valve and cylinder), and an observation window is installed on the right side of the straight discharge section (for easy observation of the internal condition of the main material discharge channel). The automatic baffle valve assembly includes a pressure reducing valve connected in series with an external air source. The system consists of a connected air pipe, a solenoid valve and cylinder mounted on the valve cylinder mounting base and connected in series via the air pipe, a crank hinged to the other end of the cylinder, a shaft with one end embedded in the other end of the crank, and a baffle inserted into the same axis of the shaft using a tenon-groove joint. (When normal production processes are required, the DCS control system sends a control command to the solenoid valve, the air pipe is connected, the cylinder is activated, the crank is rotated, the shaft and baffle rotate synchronously, and finally the baffle flips to the working position located at the open end of the sealing side. Cellulose enters the main discharge channel from the variable diameter feed channel and falls from the bottom discharge port of the main discharge channel into the connected subsequent main equipment.)When abnormal production processes such as process debugging, maintenance, or cleaning are required, the DCS control system sends control commands to the solenoid valves, connecting the air pipes, actuating the cylinders, driving the crank to rotate, and causing the shaft and baffle to rotate synchronously. Finally, the baffle flips to the auxiliary station located at the blocked discharge port, and the cellulose enters the main discharge channel from the variable diameter feed channel and falls onto the baffle, and is then sent to the intelligent storage system via the discharge chute assembly. The intelligent cleaning mechanism includes a main water pipe arranged in a winding pattern around the perimeter of the main discharge channel and connected to an external cleaning fluid storage device via a series of electric valves. Four nozzles, connected to the main water pipe in series via tees and branch pipes, are vertically inserted into the four cylinder walls of the main discharge channel and can spray cleaning fluid in a fan shape onto the inner wall in opposite directions. Around each nozzle is a sensor that monitors the change in the thickness of cellulose adhering to the inner wall of the main discharge channel in real time (when the sensor transmits the real-time monitoring signal of the change in the thickness of cellulose adhering to the inner wall of the main discharge channel to the DCS control system and after intelligent judgment, it needs to be activated). The intelligent cleaning mechanism sends an opening command to the electric valve, allowing the cleaning fluid in the external cleaning fluid storage to enter the main water pipe. It then flows along the tee to the branch water pipe, and from the corresponding nozzles, it is sprayed in a fan shape towards the inner wall of the main material discharge channel in the opposite direction for rinsing. This continues until the cellulose thickness signal from the sensor reaches the requirement to close the cleaning process. At this point, the DCS control system sends a closing command to the electric valve, stopping the cleaning. This completes the intelligent and automated cleaning process. The DCS control system, the solenoid valve in the automatic baffle valve assembly, the electric valve and sensor in the intelligent cleaning mechanism, and the transmission system in the subsequent main equipment are all linked by electrical signals. (This invention, through the linkage control of the DCS control system to automatically flip the automatic baffle valve assembly, enables flexible switching between working and auxiliary positions, meeting the intelligent automatic conversion between normal production and abnormal production states such as process debugging, maintenance, or cleaning. This invention, through the linkage of the intelligent cleaning mechanism's opening and closing, achieves intelligent and automated cleaning, providing a guarantee for the realization of unmanned and green workshops.)

[0007] In this invention, the four nozzles are arranged on the central axis of the four cylinder walls of the straight section of the material discharge channel. The two nozzles in opposite directions are arranged in an alternating vertical arrangement, and their respective fan-shaped spray areas form a complementary relationship (to achieve all-round spraying and washing of the inner cylinder wall of the material discharge channel and avoid leaving any dead corners for rinsing).

[0008] The variable diameter feeding channel described in this invention is composed of a variable diameter feeding section and an adjustable feeding section connected by bolts (by changing the adjustable feeding section to a suitable height, the overall height of the feeding channel can be flexibly adjusted to meet the feeding requirements of different materials); connecting flange I is provided at the upper and lower ends of the variable diameter feeding section, and at the upper end and middle of the adjustable feeding section (to facilitate quick replacement of the adjustable feeding section; to facilitate quick connection with the main material discharge channel).

[0009] The discharge chute assembly described in this invention includes a chute (which serves as a material channel for material to flow to an external storage system during abnormal production) consisting of a fixed end and a splicing section connected by bolts, and an extended passage hinged to the lower end of the splicing section (to facilitate adjustment of the receiving distance).

[0010] In this invention, a sealing gasket is placed between the connecting flange II at the top of the material dropping section of the main material dropping channel and the connecting flange I at the bottom of the adjusting feed section of the variable diameter feeding channel (to prevent foreign objects from entering the main material dropping channel).

[0011] In this invention, the connecting flange II located at the bottom end of the straight cylindrical section of the material discharge channel is connected to the subsequent main equipment by a threaded connection (for easy installation, maintenance and disassembly).

[0012] The working principle of this invention is as follows:

[0013] This invention features two material channels: during normal production, the automatic baffle valve assembly operates at its working position, and materials flow along the vertically connected variable-diameter feed channel and main discharge channel into the subsequent main equipment; during abnormal production, the automatic baffle valve assembly operates at its auxiliary position, and materials flow along the feed channel, the baffle in the automatic baffle valve assembly, and the discharge chute assembly into the external storage system. This invention, through the linkage control of the DCS control system, enables the automated switching between the working and auxiliary positions, facilitating intelligent automatic transitions between normal production and abnormal production states such as process debugging, maintenance, or cleaning. Furthermore, this invention achieves intelligent automatic cleaning through the linkage of the intelligent cleaning mechanism, providing a guarantee for realizing unmanned and green workshops.

[0014] More specifically, this invention includes an automatic baffle valve assembly that switches between a working station with an open, sealed side and an auxiliary station with a sealed discharge port by flipping. An intelligent cleaning mechanism is arranged around the main discharge channel. The solenoid valve in the automatic baffle valve assembly, the electric valve and sensors in the intelligent cleaning mechanism, and the transmission system in the subsequent main equipment are all linked to the DCS control system via electrical signals. When a normal production process is required, the DCS control system sends a control command to the solenoid valve, connecting the air pipe, actuating the cylinder, and rotating the crank. The shaft and baffle rotate synchronously, and finally, the baffle flips to the working station located at the open, sealed side. Cellulose enters the main discharge channel from the variable-diameter feed channel and falls from the bottom discharge port of the main discharge channel into the connected subsequent main equipment. When abnormal production processes such as process debugging, maintenance, or cleaning are required, the DCS control system sends control commands to the solenoid valves, connecting the air pipes, actuating the cylinders, and rotating the crank. The shaft and baffle rotate synchronously, and finally the baffle flips to the auxiliary station located at the blocked discharge port. Cellulose enters the main discharge channel from the variable diameter feed channel and falls onto the baffle, then is sent to the intelligent storage system via the discharge chute assembly. Whether the intelligent cleaning mechanism needs to be started or stopped is determined by sensors arranged around the nozzles that monitor the changes in the thickness of cellulose adhering to the inner wall of the main discharge channel in real time. These sensors transmit signals to the DCS control system, which then adjusts the system based on the received signals and preset values. The intelligent automatic start-stop cleaning mechanism consists of a sensor that transmits the real-time monitoring signal of the cellulose thickness change adhering to the inner wall of the main material discharge channel to the DCS control system. After intelligent judgment, if the intelligent cleaning mechanism needs to be started, it issues an opening command to the electric valve. The cleaning fluid in the external cleaning fluid storage enters the main water pipe, then flows through the three-way branch to the distribution pipe, and then sprays in a fan shape from the corresponding nozzles towards the inner wall of the main material discharge channel in the opposite direction for rinsing. When the subsequent cellulose thickness signal sent by the sensor reaches the requirement to close the cleaning, the DCS control system issues a closing command to the electric valve, and the cleaning stops. In this way, the entire process realizes intelligent and automated cleaning.

[0015] The beneficial effects of this invention are as follows:

[0016] This invention enables flexible switching between working stations and auxiliary stations, allowing for intelligent and automatic conversion between normal production states and abnormal production states such as process debugging, maintenance, or cleaning. It also enables intelligent and automatic cleaning of the cellulose feeding and discharging system, providing a guarantee for the realization of unmanned and green workshops.

The material enters the subsequent main equipment via the vertically connected variable-diameter feed channel 1 and the main discharge channel 2. During abnormal production, the automatic baffle valve assembly 3 is in an auxiliary position, and the material enters the external storage system via the variable-diameter feed channel 1, the baffles 3-7 in the automatic baffle valve assembly 3, and the discharge chute assembly 5. This invention, through the linkage control of the DCS control system 6, enables the automatic flipping of the automatic baffle valve assembly 3, facilitating flexible switching between working and auxiliary positions and meeting the intelligent automatic conversion between normal production and abnormal production states such as process debugging, maintenance, or cleaning. This invention, through the linkage of the intelligent cleaning mechanism 4, enables intelligent automatic cleaning, providing a guarantee for the realization of unmanned and green workshops. The main material discharge channel 2 is welded from a variable diameter discharge section 2-1 and a straight discharge section 2-2 (as part of the material channel). Connecting flanges II 2-3 are provided at the upper end of the variable diameter discharge section 2-1 and the lower end of the straight discharge section 2-2 (for quick installation or disassembly). A valve cylinder mounting seat 2-4 (serving as the mounting base for the pressure reducing valve 3-1 and the cylinder 3-4) is installed on the left side of the straight discharge section 2-2. An observation window 2-5 is installed on the right side of the straight discharge section 2-2 (for easy observation of the internal condition of the main material discharge channel 2). The automatic baffle valve assembly 3 includes an air pipe 3-2 connected to an external air source via a series pressure reducing valve 3-1, and a valve cylinder mounting seat 2-4. -4 is connected in series with solenoid valve 3-3 and cylinder 3-4 via air pipe, crank 3-5 hinged to the other end of cylinder, shaft 3-6 with one end embedded in the other end of crank, and baffle 3-7 inserted into the same axis line of shaft with tenon and slot joint. (When normal production process is required, DCS control system 6 sends control command to solenoid valve 3-3, air pipe 3-2 is connected, cylinder 3-4 is activated, crank 3-5 is driven to rotate, shaft 3-6 and baffle 3-7 rotate synchronously, and finally baffle 3-7 flips to the working position located at the open end of the sealing side, cellulose enters the main discharge channel 2 from the variable diameter feed channel 1, and falls from the bottom discharge port of the main discharge channel 2 into the connected subsequent main equipment.)When abnormal production processes such as process debugging, maintenance, or cleaning are required, the DCS control system 6 sends a control command to the solenoid valve 3-3, connecting the air pipe 3-2, actuating the cylinder 3-4, driving the crank 3-5 to rotate, and the rotating shaft 3-6 and baffle 3-7 rotate synchronously. Finally, the baffle 3-7 flips to the auxiliary station located at the blocked discharge port, and the cellulose enters the main discharge channel 2 from the variable diameter feed channel 1 and falls onto the baffle 3-7, and is then sent to the intelligent storage system via the discharge chute assembly 5. The intelligent cleaning mechanism 4 includes a ring arranged in a winding road shape around the perimeter of the main discharge channel, and The main water pipe 4-2, connected to the external cleaning fluid storage via a series-connected electric valve 4-1, and four nozzles 4-5, connected to the main water pipe via a three-way valve 4-3 and a branch water pipe 4-4, are vertically inserted into the four cylinder walls of the main discharge channel. These nozzles spray cleaning fluid in a fan shape onto the inner wall in opposite directions. Around each nozzle 4-5, a sensor 4-6 is arranged to monitor the change in cellulose thickness adhering to the inner wall of the main discharge channel in real time. (When the sensor 4-6 transmits the real-time monitoring signal of the change in cellulose thickness adhering to the inner wall of the main discharge channel to the DCS control system 6, it is then processed by the intelligent...) After judgment, if the intelligent cleaning mechanism 4 needs to be activated, it sends an opening command to the electric valve 4-1. The cleaning fluid in the external cleaning fluid storage enters the main water pipe 4-2, and then flows along the tee 4-3 to the branch water pipe 4-4. From the corresponding nozzle 4-5, it is sprayed in a fan shape towards the inner wall of the main discharge channel in the opposite direction for rinsing. This continues until the cellulose thickness value signal sent by the sensor 4-6 reaches the requirement to close the cleaning. At this time, the DCS control system 6 sends a closing command to the electric valve 4-1, and the cleaning stops. In this way, the entire process realizes intelligent and automated cleaning. The DCS control system 6 and the automatic... The solenoid valve 3-3 in the moving baffle valve assembly 3, the electric valve 4-1 and sensor 4-6 in the intelligent cleaning mechanism 4, and the transmission system in the subsequent main equipment are all linked together by electrical signals. (This invention enables flexible switching between working and auxiliary positions by linking the automatic baffle valve assembly 3 with the DCS control system 6, meeting the intelligent automatic conversion between normal production status and abnormal production status such as process debugging, maintenance, or cleaning. This invention enables intelligent automatic cleaning by linking the opening and closing of the intelligent cleaning mechanism 4, providing a guarantee for the realization of unmanned and green workshops.)

[0027] In this invention, the four nozzles 4-5 are arranged on the central axis of the four cylinder walls of the straight cylinder section 2-2 of the main material discharge channel 2. The two nozzles 4-5 in opposite directions are arranged in an alternating manner, and their respective fan-shaped spray areas form a complementary relationship (to achieve all-round spraying and washing of the inner cylinder wall of the main material discharge channel 2, avoiding leaving any dead corners for rinsing).

[0028] The variable diameter feeding channel 1 described in this invention is formed by bolting together a variable diameter feeding section 1-1 and an adjustable feeding section 1-2 (by changing the adjustable feeding section 1-2 to a suitable height, the overall height of the feeding channel 1 can be flexibly adjusted to meet the feeding requirements of different materials); connecting flanges I1-3 are provided at the upper and lower ends of the variable diameter feeding section 1-1, and at the upper end and middle of the adjustable feeding section 1-2 (to facilitate quick replacement of the adjustable feeding section 1-2; and to facilitate quick connection with the main material discharge channel 2).

[0029] The discharge chute assembly 5 described in this invention includes a chute 5-1 (which serves as a material channel component for material flow to an external storage system during abnormal production) formed by bolting together a chute fixed end 5-1-1 and a chute splicing section 5-1-2, and an extended passageway 5-2 (which is hinged to the lower end of the chute splicing section 5-1-2 for easy adjustment of the material receiving distance).

[0030] In this invention, a sealing gasket 8 is placed between the connecting flange II 2-3 at the top of the material dropping section 2-1 of the main material dropping channel 2 and the connecting flange I 1-3 at the bottom of the adjusting feed section 1-2 of the variable diameter feeding channel 1 (to prevent foreign objects from entering the main material dropping channel 2).

[0031] In this invention, the connecting flange II2-3 located at the bottom end of the straight cylindrical section 2-2 of the main material discharge channel 2 is connected to the subsequent main equipment by a threaded connection (for easy installation and maintenance disassembly).

[0032] The specific uses of this invention are as follows:

[0033] Before using this invention, first assemble it according to the relative assembly relationships shown in the above structural description and accompanying drawings. After the invention is assembled and connected, it can be put into normal use.

[0034] When normal production is required, the DCS control system 6 sends a control command to the solenoid valve 3-3, the air pipe 3-2 is connected, the cylinder 3-4 is activated, driving the crank 3-5 to rotate, the shaft 3-6 and the baffle 3-7 rotate synchronously, and finally the baffle 3-7 flips to the working position located at the open end of the sealing side, and the cellulose enters the main discharge channel 2 from the variable diameter feed channel 1, and falls from the bottom discharge port of the main discharge channel 2 into the connected subsequent main equipment.

[0035] When abnormal production is required, such as process debugging, maintenance, or cleaning, the DCS control system 6 sends a control command to the solenoid valve 3-3, the air pipe 3-2 is connected, the cylinder 3-4 is activated, driving the crank 3-5 to rotate, the shaft 3-6 and the baffle 3-7 rotate synchronously, and finally the baffle 3-7 flips to the auxiliary station located at the blocked discharge port. The cellulose enters the main discharge channel 2 from the variable diameter feed channel 1 and falls onto the baffle 3-7, and is then sent to the intelligent storage system through the discharge chute assembly 5. Whether the intelligent cleaning mechanism 4 needs to be started or stopped is determined by a signal transmitted to the DCS control system 6 by sensors 4-6, which are arranged around the nozzles 4-5 to monitor the changes in the thickness of cellulose adhering to the inner wall of the main discharge channel in real time. The DCS control system 6 then intelligently and automatically starts or stops the intelligent cleaning mechanism 4 based on the signal received and the preset value. That is, when the sensor 4-6 transmits the signal of the change in the thickness of cellulose adhering to the inner wall of the main discharge channel in real time to the DCS control system 6 and makes an intelligent judgment, if the intelligent cleaning mechanism 4 needs to be started, it sends an opening command to the electric valve 4-1. The cleaning fluid in the external cleaning fluid storage enters the main water pipe 4-2, and then flows through the tee 4-3 to the branch water pipe 4-4. It is then sprayed in a fan shape from the corresponding nozzles 4-5 towards the inner wall of the main discharge channel in the opposite direction for rinsing. The cleaning continues until the cellulose thickness signal sent by the sensor 4-6 reaches the requirement to close the cleaning. At this point, the DCS control system 6 sends a closing command to the electric valve 4-1, and the cleaning stops. In this way, the entire process achieves intelligent and automated cleaning.
