Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0024] Referring to Figure 1 and Figure 2 , an embodiment provided by the present utility model: a quantitative feeding mechanism for chemical equipment, including a feeding table 1, a conversion shell 2 fixedly connected inside the feeding table 1, a blanking pipe 3 fixedly connected inside the conversion shell 2, a conversion pipe 4 rotatably connected inside the conversion shell 2, a rotating rod 5 fixedly connected to the outer wall of the conversion pipe 4, a sliding rod 6 rotatably connected to the outer wall of the rotating rod 5, a fixed block 8 fixedly connected to the upper surface of the feeding table 1, a telescopic rod 7 rotatably connected inside the fixed block 8, and the output end of the telescopic rod 7 fixedly connected to the outer wall of the sliding rod 6.

A material conveying pipe 13 is fixedly connected inside the conversion shell 2, and a feeding assembly is arranged inside the feeding table 1. The feeding assembly is used for quantitatively feeding the equipment. The feeding assembly includes a quantitative pipe 14, the quantitative pipe 14 is fixedly connected inside the feeding table 1, the quantitative pipe 14 is fixedly connected to the outer wall of the material conveying pipe 13, a hydraulic rod 15 is fixedly connected to the upper surface of the quantitative pipe 14, the output end of the hydraulic rod 15 is fixedly connected to a sliding shaft 16, and a feeding pipe 17 is fixedly connected to the lower surface of the quantitative pipe 14;

[0025] Specifically, first connect the feeding pipe 17 to the inside of the processing barrel of the chemical equipment through a hose. Start the telescopic rod 7 to drive the sliding rod 6 to slide. While the sliding rod 6 slides, it drives the rotating rod 5 to rotate an angle, thereby driving the conversion pipe 4 to rotate an angle to connect with the blanking pipe 3 and the suction pipe 9. At this time, the raw material enters the inside of the blanking pipe 3 from the storage device. Start the hydraulic rod 11 to drive the piston 12 to slide to extract the raw material from the inside of the blanking pipe 3 and enter the inside of the pressure pipe 10 through the conversion pipe 4 and the suction pipe 9. Then start the telescopic rod 7 to drive the rotating rod 5 to rotate an angle, so that the conversion pipe 4 rotates an angle to connect with the material conveying pipe 13 and the suction pipe 9. Start the hydraulic rod 11 to push the piston 12 to push the raw material from the inside of the pressure pipe 10 into the material conveying pipe 13 through the suction pipe 9. Start the hydraulic rod 15 to drive the sliding shaft 16 to slide upward to suck the raw material from the inside of the material conveying pipe 13 into the quantitative pipe 14 and then extrude the raw material by pushing the sliding shaft 16 to discharge from the feeding pipe 17, thereby achieving the effect of quantitatively feeding the processing equipment.

[0026] Referring toFigure 1 and Figure 3 On the upper surface of the feeding table 1, a feed bin 19 is fixedly connected. Inside the feed bin 19, a feeding pipe 20 is fixedly connected. On the upper surface of the feeding pipe 20, a first motor 21 is fixedly connected. The output end of the first motor 21 is fixedly connected with an auger blade 22. On the outer wall of the feeding pipe 20, a material pumping pump 23 is fixedly connected. The output end of the material pumping pump 23 is fixedly connected with a material conveying pipe 24;

[0027] Specifically, start the first motor 21 to drive the auger blade 22 to rotate. Through the rotation of the auger blade 22, the raw materials inside the feed bin 19 are pumped into the inside of the feeding pipe 20, and the raw materials are slowly fed by the rotation of the auger blade 22. Start the material pumping pump 23 to pump the raw materials out of the inside of the feeding pipe 20 and convey them into the inside of the material conveying pipe 24, and then convey them into the storage device through the material conveying pipe 24 to store the raw materials, so as to assist the quantitative feeding mechanism in feeding.

[0028] Refer to Figure 1 、 Figure 3 and Figure 4 On the upper surface of the blanking pipe 3, a storage barrel 18 is fixedly connected. Inside the storage barrel 18, a feeding frame 25 is fixedly connected. On the outer wall of the feeding frame 25, a second motor 26 is fixedly connected. The output end of the second motor 26 is fixedly connected with a powder rotating cylinder 27. On the upper surface of the storage barrel 18, a third motor 28 is fixedly connected. The output end of the third motor 28 is fixedly connected with a stirring blade 29. The output end of the third motor 28 is fixedly connected with a scraping rod 30;

[0029] Specifically, after the raw materials enter the inside of the feeding frame 25, start the second motor 26 to drive the powder rotating cylinder 27 to rotate. Through the rotation of the powder rotating cylinder 27, the effect of slowly feeding and storing the raw materials is achieved, preventing the raw materials from being blocked when entering the inside of the storage barrel 18. After the raw materials enter the inside of the storage barrel 18 through the feeding frame 25, start the third motor 28 to drive the stirring blade 29 to rotate. The raw materials are stirred by the stirring blade 29 to prevent the liquid raw materials from solidifying, and at the same time, it can also play an auxiliary feeding effect. The third motor 28 also drives the scraping rod 30 to rotate. Through the rotation of the scraping rod 30, it effectively prevents the raw materials from adhering to the inner wall of the storage barrel 18 during the raw material feeding process, which not only plays a role in storing and protecting the raw materials during the raw material storage process, but also plays an auxiliary role in quantitatively feeding the processing barrel.

[0030] Working principle: When quantitative feeding is required for the processing equipment in chemical equipment, first connect the feeding pipe 17 to the processing equipment through a hose or pipeline. At this time, start the first motor 21 to drive the auger blade 22 to rotate, sucking the raw materials inside the material box 19 into the inside of the feeding pipe 20. The raw materials are slowly conveyed through the rotation of the auger blade 22, and then start the material suction pump 23 to suck the raw materials into the inside of the material conveying pipe 24. The raw materials enter the feeding frame 25 through the material conveying pipe 24. Start the second motor 26 to drive the powder rotating cylinder 27 to rotate to achieve slow feeding, and the raw materials slowly enter the inside of the storage barrel 18 to prevent blockage when storing the feed. After the raw materials enter the storage barrel 18, start the third motor 28 to drive the stirring blade 29 and the scraping rod 30 to rotate. When the raw materials are stored inside the storage barrel 18, they are stirred by the stirring blade 29 to prevent the solidification of liquid raw materials. The scraping rod 30 can prevent the raw materials from adhering to the inner wall of the storage barrel 18 during the feeding process. When quantitative feeding is required, a valve is provided inside the feeding pipe 3. First, start the telescopic rod 7 to drive the sliding rod 6 to slide. During the sliding process of the sliding rod 6, it drives the rotating rod 5 to rotate an angle. The rotation of the rotating rod 5 drives the conversion pipe 4 to rotate and connect with the feeding pipe 3 and the material suction pipe 9. At this time, open the valve inside the feeding pipe 3, and the raw materials enter the inside of the feeding pipe 3. Start the first hydraulic rod 11 to drive the piston 12 to slide and suck the raw materials through the feeding pipe 3 and the material suction pipe 9 into the inside of the pressure feeding pipe 10. Due to the size limitation of the pressure feeding pipe 10, only a certain amount of raw materials can be stored inside. At this time, start the telescopic rod 7 to drive the sliding rod 6 to slide and drive the rotating rod 5 and the conversion pipe 4 to rotate an angle, so that the conversion pipe 4 is connected between the material conveying pipe 13 and the material suction pipe 9. At this time, start the first hydraulic rod 11 to drive the piston 12 to slide and push the raw materials inside the pressure feeding pipe 10 into the inside of the material conveying pipe 13 through the material suction pipe 9. After the raw materials enter the inside of the material conveying pipe 13, start the second hydraulic rod 15 to drive the sliding shaft 16 to slide and suck the raw materials into the inside of the quantitative pipe 14 through the material conveying pipe 13. The raw materials are squeezed into the inside of the feeding pipe 17 by driving the sliding shaft 16 to press down by the second hydraulic rod 15 and then discharged, thus achieving the effect of quantitative feeding for chemical processing equipment.

[0031] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
