[0032] A powder metering and proportioning integrated device, as Figures 1 - 3As shown in the figure, it includes a metering and proportioning workbench 10 for catalyst production. A rotating disk 20 is installed on the top surface of the metering and proportioning workbench 10. Above the metering and proportioning workbench 10, several groups of feeding cylinders 30 are installed in a uniformly spaced circular arrangement and inclined upward. The bottom of each group of feeding cylinders 30 is connected to the top surface of the metering and proportioning workbench 10 through columns. The discharging ends of each group of feeding cylinders 30 are located at the same center, and a collecting hopper 50 is arranged directly below the center. A servo stepping motor 11 for driving the rotation of the rotating disk 20 is embedded in the top surface of the metering and proportioning workbench 10. A plurality of uniformly spaced circular grooves 21 are formed on the top surface of the rotating disk 20. A metering and weighing seat 22 is installed in each groove 21, and a weighing and proportioning cylinder is installed on the metering and weighing seat 22. A spiral feeding shaft 33 is installed in the feeding cylinder 30. A servo motor 31 for driving the rotation of the spiral feeding shaft 33 is installed at one end of the feeding cylinder 30 away from the discharging port. A feeding pipe 32 is installed at the top of the outer wall of the feeding cylinder 30 near the servo motor 31. By installing the rotating disk 20 on the top surface of the metering and proportioning workbench 10 and driving the rotation of the rotating disk 20 by the embedded servo stepping motor 11, each metering and weighing seat 22 on the rotating disk 20 can be rotated to directly below the collecting hopper 50 in sequence, facilitating the collection and proportioning operations of the metered materials. The spiral feeding shaft 33 installed in the feeding cylinder 30 can accurately control the conveying amount of the materials under the drive of the servo motor 31. The discharging ends of each group of feeding cylinders 30 are located at the same center, and a collecting hopper 50 is arranged directly below the center, so that the materials conveyed from each feeding cylinder 30 can be concentrated in the collecting hopper 50, and then weighed and proportioned through the metering and weighing seat 22 at the bottom. The operation is simple.

[0033] Further, a feeding hopper 34 is installed at the top of the feeding pipe 32. The feeding hopper 34 and the feeding pipe 32 are in interference fit, ensuring the tightness of the connection, preventing the leakage of powder during transmission, and also facilitating installation or disassembly.

[0034] Specifically, the outer wall of the collecting hopper 50 is connected to the bottom of the feeding cylinder 30 through several groups of connecting frames 51. A dust collection cover 60 is arranged directly above the collecting hopper 50. A connecting pipe 62 is installed on the outer wall of the dust collection cover 60. The design of the dust collection cover 60 effectively reduces the dust generated during the proportioning process of the powder, improves the working environment, and protects the health of the operators.

[0035] It should be noted that the bottom edge of the dust collection cover 60 is connected to the top of the feeding cylinder 30 through a fixing frame 63, ensuring the stability and reliability of the dust collection cover 60, enabling it to work for a long time and efficiently.

[0036] Among them, the connecting pipe 62 is externally connected to a negative pressure chassis 64 through a negative pressure pipe 62. A dust collection cloth bag 65 is installed inside the negative pressure chassis 64. Through the suction generated by a negative pressure fan, the dust collected in the dust collection hood 60 is sucked in and filtered, realizing the centralized treatment and recycling of the dust.

[0037] In addition, the dust collection cloth bag 65 is sleeved at the nozzle of the negative pressure pipe 62. The negative pressure chassis 64 is connected to a negative pressure fan, ensuring the sealing between the dust collection cloth bag 65 and the negative pressure pipe 62, preventing the leakage of dust. The easy-to-replace design of the dust collection cloth bag 65 also facilitates the long-term maintenance and upkeep of the equipment.

[0038] The working principle of this powder metering and proportioning integrated device:

[0039] First, the operator adds different powders into each feeding cylinder 30 through the feeding pipe 32;

[0040] Then, the servo motor 31 is started. The servo motor 31 drives the spiral feeding shaft 33 to rotate, and the spiral feeding shaft 33 starts to convey the powder in the feeding cylinder 30 towards the discharge port; Since the spiral feeding shaft 33 can precisely control the conveying amount of the material, relatively accurate feeding can be achieved;

[0041] At the same time, the servo stepping motor 11 embedded in the top surface of the metering and proportioning workbench 10 is started, driving the rotating disk 20 to rotate; A number of grooves 21 are evenly and equidistantly arranged in a ring shape on the top surface of the rotating disk 20. A weighing and proportioning cylinder is installed on the weighing and proportioning seat 22 in each groove 21; As the rotating disk 20 rotates, each weighing and proportioning seat 22 rotates in turn;

[0042] When the weighing and proportioning seat 22 rotates to directly below the aggregate hopper 50, the powders conveyed from the discharge ends of each feeding cylinder 30 are concentrated and fall into the aggregate hopper 50, and then fall into the weighing and proportioning cylinders on the corresponding weighing and proportioning seats 22 below for metering;

[0043] After metering and proportioning, according to the production requirements, the materials in the weighing and proportioning cylinders can be collected for the next step of catalyst production operation.

[0044] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art of this industry should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only preferred examples of the present invention and are not used to limit the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed. The scope of protection claimed by the present invention is defined by the appended claims and their equivalents.
