Description

Technical Field

[0001] This utility model relates to a cotton powder metering chamber, specifically a metering chamber capable of eliminating cotton powder bridging. Background Technology

[0002] A cotton powder metering silo is a device used in specific production processes to store and accurately measure cotton powder. Refer to patent publication number CN212768681U - Chinese Utility Model Patent: Anti-clogging Cotton Powder Silo for Cellulose Production. The existing cotton powder metering silo works by having cotton powder enter through the inlet and accumulate to a certain amount. A weighing module monitors the weight of the cotton powder in real time. When the set formula quantity is reached, the system sends a signal to stop feeding, and the cotton powder is transported to the next production stage for further processing. However, the conical silo design in the aforementioned patent solution can easily cause "bridging" when the cotton powder is compressed at the bottom, thus affecting the normal discharge of cotton powder. Utility Model Content

[0003] The main purpose of this utility model is to provide a cotton powder metering bin to solve the problem that the conical bin design of existing anti-clogging cotton powder bins for cellulose production causes the cotton powder at the bottom to be compacted, which easily forms a bridging phenomenon and affects the normal discharge of cotton powder.

[0004] To achieve the above objectives, this utility model provides a cotton powder metering chamber, including a cylindrical shell and a support. The top of the support is fixedly connected to the cylindrical shell, and a meter is provided at the bottom. The top wall of the cylindrical shell has a feed inlet, and the bottom has a constriction structure. The constriction end of the constriction structure is coaxially connected to the barrel body. The ring wall of the barrel body is connected to a horizontal pipe. A first auger is coaxially rotated inside the horizontal pipe. One end of the first auger is located inside the barrel body, and the other end is connected to a drive component for driving its rotation. The chamber also includes a pulse body.

[0005] The pulse body is connected to a gas supply pipe. One end of the gas supply pipe passes through the shell and connects to the first branch pipe. The outlet of the first branch pipe faces the opening end of the constriction structure.

[0006] A preferred embodiment is that the support includes multiple legs, which are circumferentially fixed to the annular wall of the cylindrical shell, and a meter is installed at the end of each leg away from the cylindrical shell.

[0007] A preferred embodiment is that the drive unit includes a frame and a first motor;

[0008] The frame includes multiple support rods, one end of which is fixedly connected to the side wall of the horizontal pipe away from the barrel, and the other end is fixedly fitted with a mounting plate.

[0009] The base of the first motor is fixedly connected to the mounting plate, and the output shaft is coaxially connected to the shaft of the first auger.

[0010] A preferred embodiment is that the cotton powder metering chamber further includes a second branch pipe, one end of which is connected to the connection between the first branch pipe and the air supply pipe, and the air outlet faces the inner top wall of the cylinder shell.

[0011] The first branch pipe, the second branch pipe, and the gas transmission pipe form a Y-shaped pipe body.

[0012] A preferred embodiment is that the cotton powder metering bin also includes a feeding mechanism, which includes a hopper, an inclined pipe, and a second auger.

[0013] The inclined tube is connected to the bottom of the hopper at its bottom and to a connecting tube near the top. The end of the connecting tube away from the inclined tube is inserted into the feed inlet. The annular wall of the inclined tube does not contact the top wall of the cylinder.

[0014] The second auger is coaxially mounted inside the inclined tube, with one end of the second auger connected to the second motor, and the base of the second motor fixedly connected to the top of the inclined tube.

[0015] A preferred embodiment is to fix an inclined plate inside the hopper, with the bottom end of the inclined plate located on the feed inlet side of the inclined tube.

[0016] A preferred embodiment is that a lifting plate is coaxially arranged inside the cylinder shell, and the top of the lifting plate is connected to a drive component for driving it to move axially along the cylinder shell.

[0017] The lifting plate has two notches. One notch allows the connecting pipe to pass through, and the other notch allows the Y-shaped pipe to pass through. The top wall of the lifting plate can contact the top wall of the cylinder shell through the driving component.

[0018] A preferred embodiment is that the driving component includes multiple cylinders, the cylinder seats of the multiple cylinders are fixedly connected to the top wall of the cylinder shell, and the piston rods are inserted into the cylinder shell and fixedly connected to the lifting plate.

[0019] The beneficial effects of the above scheme are:

[0020] Cotton powder enters the cylinder through the feed inlet on the top wall and accumulates at the bottom constriction structure. A metering device located at the bottom of the support monitors the weight of the cotton powder in the cylinder in real time. When the set formula quantity is reached, feeding stops. During the discharge process, if bridging occurs and affects normal discharge, the pulse main unit is activated. The pulse main unit delivers airflow to the first branch pipe through the air supply pipe. The air outlet of the first branch pipe faces the opening end of the constriction structure. The pulsed airflow impacts the cotton powder at the constriction structure, breaking up the bridging structure and allowing the cotton powder to fall smoothly. Simultaneously, the drive unit is activated, driving the first auger to rotate coaxially within the horizontal pipe. The first auger, located at one end inside the cylinder, conveys the cotton powder inside the cylinder, transporting it from the cylinder through the horizontal pipe to the next production stage for further processing. Through the pulsed airflow breaking up bridging and the conveying action of the first auger, the cotton powder is ensured to discharge normally and smoothly from the metering bin.

Detailed Implementation

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Many specific details are set forth in the following description to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below. Example

[0031] like Figure 1 As shown, this embodiment provides a cotton powder metering chamber, including a cylindrical shell 10 and a support 20. The top of the support 20 is fixedly connected to the cylindrical shell 10, and a metering device 1 is installed at the bottom of the support 20. The metering device 1 adopts an existing technology weight meter, and models such as IND245, IND249, IND560, PowerCell PDX, ICS689, SIWAREX WP321, FS10 / FS20 series, and AW series can be selected. The support 20 includes multiple legs 21, which are circumferentially fixed to the annular wall of the cylindrical shell 10. The metering device 1 is installed at the end of each leg 21 away from the cylindrical shell 10. The top wall of the cylindrical shell 10 has an inlet 11, and the bottom has a constriction structure 12. The constriction end of the constriction structure 12 is coaxially connected to the barrel body 13, and the annular wall of the barrel body 13 is connected to a horizontal pipe 14, such as... Figure 3As shown, a first auger 30 is coaxially mounted inside the horizontal pipe 14. One end of the first auger 30 is located inside the barrel 13, and the other end of the first auger 30 is connected to a drive unit 31 for driving its rotation. The drive unit 31 includes a frame 310 and a first motor 311. The frame 310 includes multiple support rods 3101. One end of the multiple support rods 3101 is fixedly connected to the side wall of the horizontal pipe 14 away from the barrel 13, and the other end of the multiple support rods 3101 is fixedly mounted on a mounting plate 3102. The base of the first motor 311 is fixedly connected to the mounting plate 3102, and the output shaft of the first motor 311 is coaxially connected to the shaft of the first auger 30. A pulse body 40 is also included. The pulse body 40 is connected to an air supply pipe 41. One end of the air supply pipe 41 passes through the barrel shell 10 and connects to a first branch pipe 42. The outlet of the first branch pipe 42 faces the opening end of the constriction structure 12. The pulse body uses existing technology, so it will not be described in detail. Available models include: DMC24, DMC36, PPC32, PPC64, SUP-GMCSQ_0.8, SUP-GMCSQ_3, DMF-Y-25, DMF-Y-40S, etc.

[0032] Cotton powder enters the cylinder 10 through the feed inlet 11 on the top wall of the cylinder 10 and accumulates at the bottom constriction structure 12. A meter 1, located at the bottom of the support 20, monitors the weight of the cotton powder in the cylinder 10 in real time. When the set formula quantity is reached, feeding stops. During discharge, if bridging occurs and affects normal discharge, the pulse main body 40 is activated. The pulse main body 40 delivers airflow to the first branch pipe 42 through the air supply pipe 41. The air outlet of the first branch pipe 42 faces the opening end of the constriction structure 12. The pulsed airflow impacts the cotton powder at the constriction structure 12, breaking up the bridging structure and allowing the cotton powder to fall smoothly. Simultaneously, the drive unit 31 is activated, driving the first auger 30 to rotate coaxially within the horizontal pipe 14. The end of the first auger 30 located inside the barrel 13 conveys the cotton powder within the barrel 13, transporting it from the barrel 13 through the horizontal pipe 14 to the next production stage for further processing. By disrupting the bridging phenomenon through pulsed airflow and utilizing the conveying action of the first auger 30, the cotton powder can be discharged normally and smoothly from the metering bin.

[0033] like Figure 4As shown, the cotton powder metering chamber also includes a second branch pipe 43. One end of the second branch pipe 43 is connected to the connection between the first branch pipe 42 and the air supply pipe 41, and the air outlet of the second branch pipe 43 faces the inner top wall of the cylinder shell 10. The first branch pipe 42, the second branch pipe 43, and the air supply pipe 41 form a Y-shaped pipe body 44. The first branch pipe 42 directly impacts the closing structure 12 with pulsed airflow, breaking the "bridging" formed by the compacted cotton powder and ensuring the smooth falling of the cotton powder at the bottom. The air outlet of the second branch pipe 43 faces the inner top wall of the cylinder shell 10, preventing cotton powder from accumulating or clumping near the feed inlet 11, avoiding poor feeding or abnormal internal pressure due to top blockage. The combined effect of the two airflows covers cotton powder areas at different heights within the cylinder shell 10, significantly reducing the overall risk of blockage.

[0034] like Figure 1 The cotton powder metering hopper also includes a feeding mechanism 50, which comprises a hopper 51, an inclined pipe 52, and a second auger 53. The bottom end of the inclined pipe 52 is connected to the bottom of the hopper 51, and a connecting pipe 54 is connected to the inclined pipe 52 near its top. The end of the connecting pipe 54 away from the inclined pipe 52 is inserted into the feed inlet 11. The annular wall of the inclined pipe 52 does not contact the top wall of the cylinder shell 10. For example... Figure 5 As shown, the second auger 53 is coaxially mounted inside the inclined tube 52. One end of the second auger 53 is connected to the second motor 55, and the base of the second motor 55 is fixedly connected to the top of the inclined tube 52. An inclined plate 510 is fixedly installed inside the hopper 51, with its bottom end located on one side of the feed inlet 11 of the inclined tube 52. Cotton powder is poured into the hopper 51. The inclined plate 510 guides the cotton powder towards the inclined tube 52, preventing material accumulation at the bottom of the hopper 51. The cotton powder enters the conveying system through the inclined tube 52 at the bottom of the hopper 51. The inclined tube 52 is inclined, using gravity to accelerate the cotton powder's descent. The second auger 53 is coaxially mounted inside the inclined tube 52, with one end connected to the first motor 311. After the first motor 311 starts, the second auger 53 rotates, pushing the cotton powder upwards along the inclined tube 52. The connecting pipe 54 at the top of the inclined pipe 52 is inserted into the feed inlet 11 of the metering chamber to transport cotton powder into the cylinder shell 10. The annular wall of the inclined pipe 52 does not contact the top wall of the cylinder shell 10 to avoid friction or interference. The feed rate is adjusted by the rotation speed of the second auger 53 to ensure that the cotton powder enters the metering chamber stably and quantitatively.

[0035] like Figure 4 , Figure 6As shown, a lifting plate 60 is coaxially arranged inside the cylindrical shell 10. The top end of the lifting plate 60 is connected to a drive member 61 for driving its axial movement along the cylindrical shell 10. The lifting plate 60 has two notches 601. One notch 601 can pass through the connecting pipe 54, and the other notch 601 can pass through the Y-shaped pipe 44. The top wall of the lifting plate 60 can contact the top wall of the cylindrical shell 10 through the drive member 61. The drive member 61 includes multiple cylinders. The cylinder seats of the multiple cylinders are fixedly connected to the top wall of the cylindrical shell 10, and the piston rods are inserted into the cylindrical shell 10 and fixedly connected to the lifting plate 60. According to the material demand, the lifting plate 60 is driven to move axially within the cylinder shell 10 by the drive component 61, adjusting the distance between the lifting plate 60 and the top wall of the cylinder shell 10. The two notches 601 of the lifting plate 60 are coaxially aligned with the connecting pipe 54 and the Y-shaped pipe 44 inside the cylinder shell 10, respectively, to ensure that the pipe structure is not interfered with during the lifting process. The cylinder piston rod retracts, and the lifting plate 60 rises to contact the top wall of the cylinder shell 10. At this time, the storage volume inside the cylinder shell 10 is at its maximum. Cotton powder enters the cylinder shell 10 through the feed port 11 and accumulates in the space between the lifting plate 60 and the top wall. It settles naturally by gravity. The cylinder piston rod slowly extends, driving the lifting plate 60 to move downward, applying axial pressure to the accumulated cotton powder, pre-compressing the loose cotton powder, and reducing internal voids.

[0036] Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
