Description

Technical Field

[0001] This utility model relates to the technical field of feeding devices, specifically a rotary metering feeding device for a reaction vessel. Background Technology

[0002] Reactors are widely used in industries such as petroleum, chemical, rubber, pesticide, dye, pharmaceutical and food. During the production reaction process, various auxiliary materials need to be prepared and added into the reactor in proportion. The quantitative control of the auxiliary materials is required during the addition process. However, in production, most of the time, manual transportation is carried out using a trolley and weighing is done by a mobile electronic scale before the raw materials are added. During this process, there are safety hazards such as unstable transportation and material shaking, as well as fluctuations in measurement, which ultimately affect the finished product indicators. Therefore, an automatic feeding device is needed.

[0003] In the prior art, patent CN201210111995.X discloses an automatic weighing and discharging plastic granule feeder, including a feeder body and a feeding device. A dryer is installed at the outlet of the feeding device. The feeder body contains a material retention bin and a weighing retention bin arranged sequentially from top to bottom. A material discharge valve is located at the bottom of the material retention bin, and a weighing discharge valve is located at the bottom of the weighing retention bin. During operation, the material discharge valve is normally open, allowing material to remain in the weighing retention bin and be discharged through the weighing discharge valve after weighing. The material discharge valve controls the height of the material in the weighing retention bin. When the height of the material in the weighing retention bin is too high, the material discharge valve is closed to prevent excessive material accumulation in the weighing retention bin, which could lead to inaccurate weighing. By controlling the weight of the fed material, the feeding speed of the feeder is effectively controlled, thereby precisely controlling production quality parameters.

[0004] The aforementioned patent provides an automatic weighing feeder. Although the device can automatically close the material discharge valve when the material height in the weighing hopper is too high, preventing excessive material accumulation in the weighing hopper and inaccurate weighing, and effectively control the feeding speed of the feeder by controlling the weight of the feed material; however, the device still requires manual conveying of the material to the feeding device of the feeder before it can be conveyed by the feeding auger, resulting in a low degree of automation. During frequent raw material transportation, excessive human intervention leads to high labor intensity. Furthermore, manual conveying of material to the feeding device can cause material spillage; further improvements are needed. Summary of the Invention

[0029] The following description, in conjunction with the accompanying drawings and specific embodiments, provides further details:

[0030] Example 1

[0031] like Figure 1 , Figure 2 and Figure 3As shown, a rotary metering and feeding device for a reactor includes a material box 1, a feeding auger 2, a weighing device 4, a reactor 6, and a raw material barrel 9. It also includes a rotary mechanism 7 and a rotary frame 8. A barrel pressing device 10 is lifted and lowered at the upper end of the rotary frame 8, and a flared mouth pressing seat 1002 that can be inserted into the mouth of the raw material barrel 9 is provided at the lower end of the barrel pressing device 10. The rotary frame 8 is rotatably mounted on the side of the material box 1 through the rotary mechanism 7, and the upper end of the barrel pressing device 10 is inserted into the mouth of the material box 1 as the rotary frame 8 is rotated. The material box 1 includes a placement frame 101 and a box body 102, and the box body 102 is located in the placement frame 101. The rotary frame 8 is rotatably mounted on the side of the placement frame 101, and a pair of rotary mechanisms 7 are symmetrically arranged on the adjacent sides of the placement frame 101 and the rotary frame 8. The rotary frame 8 is rotatably set through the rotary mechanism 7. The raw material drum 9 adopts a drum structure with end caps. During use, the end caps can be briefly opened, and the drum 9 is placed on the tilting frame 8. The drum pressing device 10 is then attached to the opening of the drum 9, allowing the tilting frame 8 to tilt the drum 9. The upper port of the drum pressing device 10 is then inserted into the opening of the material bin 1, enabling the tilting frame 8 to automatically fill the material bin 1 with raw materials. When the drum pressing device 10 abuts against the raw material drum 9 and tilts it, it presses and seals the opening of the drum 9, preventing damage caused by prolonged exposure of the raw materials inside the drum 9 to air. The raw material drum 9 uses a specific size and material to ensure accurate docking with the drum pressing device 10, guaranteeing no leakage at the joint between the drum 9 and the drum pressing device 10 when the drum 9 is tilted by the tilting frame 8.

[0032] like Figure 1 and Figure 2 As shown, the flipping mechanism 7 includes a first connecting rod 701, a second electric telescopic rod 702, and a second connecting rod 703. One end of the first connecting rod 701 is rotatably mounted on the placement frame 101, and the other end is rotatably connected to the second connecting rod 703. The end of the second connecting rod 703 away from the first connecting rod 701 is rotatably mounted on the frame of the flipping frame 8. The flipping mechanism 7 drives the first connecting rod 701 to rotate via the second electric telescopic rod 702. During the rotation of the first connecting rod 701, since the lengths of the first connecting rod 701 and the second connecting rod 703 do not change, and the flipping frame 8 is rotatably mounted on the material box 1, the first connecting rod 701 and the second connecting rod 703 can drive the flipping frame 8 to flip around its rotatably mounted position. One end of the second electric telescopic rod 702 is rotatably mounted on the placement frame 101, and the other end is rotatably mounted on the rod body of the first connecting rod 701.

[0033] like Figure 1 and Figure 2As shown, the flipping frame 8 includes a back plate 802. The end of the second connecting rod 703 away from the first connecting rod 701 is rotatably mounted on the side of the back plate 802, thereby pushing the flipping frame 8 to flip. The upper end of the back plate 802 is provided with a mounting rod 801, and a pair of side plates 803 are symmetrically arranged on both sides. Multiple translation rollers 804 are arranged parallel to the lower end of the pair of side plates 803. The upper end of the placement frame 101 is provided with a rotating seat 103 near the flipping frame 8, and the mounting rod 801 is rotatably mounted on the rotating seat 103. The raw material barrel 9 is placed on the translation rollers 804. The barrel pressing device 10 includes a fixed pipe plug 1001. The lower end of the fixed pipe plug 1001 is provided with a flared mouth pressing seat 1002. The side of the fixed pipe plug 1001 is provided with a second motor 1003, and the output shaft of the second motor 1003 extends into the fixed pipe plug 1001 and is provided with an opening and closing plate 1004. A second motor 1003 is provided on the side of the fixed pipe plug 1001. The output shaft of the second motor 1003 extends into the fixed pipe plug 1001 and an opening and closing plate 1004 is provided inside. By setting the opening and closing plate 1004 and rotating it through the second motor 1003, the fixed pipe plug 1001 can be closed and opened. This allows the raw material barrel 9 to be sealed by closing the opening and closing plate 1004 when the tilting frame 8 is not tilted. After the tilting is completed, the raw materials in the raw material barrel 9 can be put into the material box 1 by opening the opening and closing plate 1004.

[0034] like Figures 3-5As shown, a pair of lifting connecting rods 1005 are symmetrically arranged on the side of the fixed pipe plug 1001 corresponding to the position of the side plate 803. The pair of lifting connecting rods 1005 pass through the side plate 803 on the same side and are connected to the hydraulic lifting column 1006. The side plate of the tilting frame 8 is provided with sliding grooves 805 corresponding to the positions of each lifting connecting rod 1005. The lifting connecting rod 1005 passes through the sliding grooves 805 and is connected to the hydraulic lifting column 1006. The hydraulic lifting column 1006 can drive the fixed pipe plug 1001 to lift and lower, thereby controlling the flared mouth pressure seat 1002 to descend and abut against the mouth of the raw material barrel 9. The flared mouth pressure seat 1002 is fitted onto the outside of the mouth of the raw material barrel 9. At the same time, the flared mouth pressure seat 1002 is also provided with a sealing platform that matches the end face of the mouth of the raw material barrel 9. A sealing gasket is provided on the sealing platform so that the flared mouth pressure seat 1002 can be tightly installed on the raw material barrel 9. A first clamping plate 11 and a second clamping plate 12 are provided on the side plate 803. The first clamping plates 11 of the pair of side plates 803 are clamped relative to each other on the barrel body of the raw material barrel 9, and the second clamping plates 12 of the pair of side plates 803 are clamped relative to each other at the junction of the raw material barrel 9 and the flared mouth pressure seat 1002. The first clamping plate 11 includes a first hydraulic telescopic rod 1101, which is provided on the side plate 803, and the first clamping plate 11 is clamped on the raw material barrel 9 by the first hydraulic telescopic rod 1101. The second clamping plate 12 includes a second hydraulic telescopic rod 1201, which is provided on the side plate 803, and the second clamping plate 12 is clamped on the junction of the raw material barrel 9 and the flared mouth pressure seat 1002 by the second hydraulic telescopic rod 1201. When the raw material barrel 9 is placed on the translation roller 804, the first clamping plate 11 can be controlled by the first hydraulic telescopic rod 1101 on the side plates 803 on both sides to clamp the raw material barrel 9 onto the barrel body, thus clamping the raw material barrel 9 and preventing it from shaking. At the same time, the second clamping plate 12 can be controlled by the second hydraulic telescopic rod 1201 to clamp the raw material barrel 9 at the joint with the flared mouth pressure seat 1002, which not only enhances the joint strength between the raw material barrel 9 and the flared mouth pressure seat 1002, but also further increases the sealing strength.

[0035] like Figure 1 and Figures 6-8As shown, the lower end of the feeding auger 2 is connected to the material box 1, and the upper end is positioned above the weighing device 4. The lower end of the weighing device 4 is equipped with a material distribution device 5, and the lower end of the material distribution device 5 is equipped with a discharge cloth 505 extending into the reactor 6. The feeding auger 2 lifts the material using a spiral auger, conveying it from the material box 1 to the weighing device 4 above. It also includes a fixing frame 3, which positions the weighing device 4 above the reactor 6. The weighing device 4 includes a weighing funnel 401 and a gravity sensor 402. An installation edge 403 extends from the upper side of the weighing funnel 401, and support legs 404 are located at the four corners of the bottom of the installation edge 403. The gravity sensor 402 is located at the bottom of the support legs 404. The weighing funnel 401 is mounted on the fixing frame 3 via the gravity sensor 402; the lower end of the weighing funnel 401 is equipped with the material distribution device 5. Weighing device 4 weighs materials using gravity sensor 402. Through multiple experiments and calculations, the accuracy of the weight of materials in weighing funnel 401 by gravity sensor 402 is ensured. When materials are conveyed into weighing device 4, the weight of weighing funnel 401 can be detected in real time by gravity sensor 402. Distributing device 5 includes a first motor 501 and a first electric telescopic rod 503. Distributing roller 502 is rotated in distributing device 5 by the first motor 501. Multiple distributing grooves 506 are sequentially opened on the distributing roller 502 along its circumference. A discharge cloth cylinder 505 is provided at the lower end of distributing device 5. The first electric telescopic rod 503 is provided on the side of distributing device 5 at the position corresponding to the lowest distributing groove 506. A wiping head 504 adapted to the distributing groove 506 is provided on the telescopic end of the first electric telescopic rod 503. The dispensing device 5 is fixedly mounted on the lower end of the weighing device 4 via a steel frame, and the weighing of the gravity sensor 402 is calculated by subtracting the weight of the dispensing device 5 and the weighing funnel 401 itself. Simultaneously, the lower end of the dispensing device 5 is equipped with a discharge cloth 505, ensuring that the weighing device 4 is supported solely by the gravity sensor 402 on the fixed frame 3, with no additional force on either side, thus guaranteeing the accuracy of the weighing device 4. The first motor 501 in the dispensing device 5 is programmed and controlled by an external control device to rotate intermittently, allowing each dispensing trough 506 to gradually move the raw material from the weighing funnel 401. As the dispensing trough 506 rotates to the position of the discharge cloth 505, the raw material is fed into the reaction vessel 6. Simultaneously, during the intermittent intervals of the first motor 501, the first electric telescopic rod 503, driven by the external control device, extends the wiping head 504 into the lowest dispensing trough 506 to wipe it, preventing raw material from adhering inside. Furthermore, the first motor 501 and the first electric telescopic rod 503 are programmed and controlled by an external control device to work in a staggered manner, so that there is no interference between the dispensing roller 502 and the wiping head 504.The material dispensing device 5 has a through hole on the side corresponding to the wiping head 504. When the wiping head 504 is not wiping, the end of the wiping head 504 near the material dispensing trough 506 stays in the through hole, which can seal the outer shell of the material dispensing device 5 and prevent material from leaking out through the through hole. When it is needed to work, the first electric telescopic rod 503 drives the wiping head 504 to extend to the lowest part of the material dispensing trough 506 for wiping. After wiping, it will return to the state of sealing the through hole, without affecting the normal rotation of the material dispensing roller 502.

[0041] The working principle of this utility model is as follows: During operation, the second electric telescopic rod 702 drives the first connecting rod 701 and the second connecting rod 703 to rotate, thereby driving the tilting frame 8 to tilt, so that the raw material barrel 9 is connected to the material box 1 through the barrel pressing device 10. Then, the second motor 1003 is controlled to drive the opening and closing plate 1004 to rotate, so that the raw materials inside the raw material barrel 9 can be put into the material box 1. The raw materials are then transported to the weighing device 4 by the feeding auger 2. The weight of the raw materials is detected by the gravity sensor 402. After the specified weight of raw materials is put in, the first motor 501 controls the distributing roller 502 to rotate intermittently, gradually putting the raw materials into the reaction vessel 6. During the intermittent intervals of the first motor 501, the first electric telescopic rod 503 drives the wiping head 504 to extend into the bottom distributing groove 506 through the external control device to wipe and prevent raw materials from adhering inside.

[0042] In summary, this utility model, by setting a flipping frame 8 driven by a flipping mechanism 7 on the side of the material bin 1, can automatically flip the raw material barrel 9 into the material bin 1 for feeding. Only manual placement of the raw material barrel on the flipping frame 8 is required, which effectively reduces the workload of employees in feeding materials. At the same time, the automatic flipping feeding by the flipping frame 8 avoids the problem of material spillage caused by improper manual operation. By setting a distributing device 5, the raw materials weighed in the weighing device 4 can be gradually fed into the reaction vessel 6. Through the alternating operation of the first motor and the first electric telescopic rod 503, the distributing trough 506 at the bottom can be cleaned in a timely manner to prevent the raw materials from clumping in the distributing trough 506 and to improve the service life of the distributing device 5.

[0043] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
