Description

Technical Field

[0001] The present invention relates to the technical field of feeding devices, and particularly to a tipping metering feeding device for a reaction kettle. Background Art

[0002] Reaction kettles are widely used in industries such as petroleum, chemical engineering, rubber, pesticides, dyes, pharmaceuticals, and food. During the production reaction process, various auxiliary materials need to be prepared and put into the reaction kettle for proportioning and addition. During the addition process, quantitative control of the auxiliary materials is required. However, in production work, most are transported manually by a small cart, weighed and measured by a mobile electronic scale, and then the raw materials are added. During this period, there are potential safety hazards such as unstable transportation and shaking of the materials, and there are also influences of metering fluctuations, ultimately affecting the finished product indicators; therefore, a device that can automatically feed materials is needed.

[0003] In the prior art, the invention patent with the patent number CN201210111995.X discloses an automatic weighing and discharging plastic particle feeding machine, including a feeding machine body and a material guiding device. A dryer is arranged at the outlet of the material guiding device. In the feeding machine body, a material retention bin and a weighing retention bin are arranged in sequence from top to bottom. A material discharge valve is arranged at the bottom of the material retention bin, and a weighing discharge valve is arranged at the bottom of the weighing retention bin. During operation, the material discharge valve is normally open, so that the material can stay in the weighing retention bin, and after weighing, it is discharged through the weighing discharge valve. 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 accumulation of materials in the weighing retention bin from causing inaccurate weighing. By controlling the weight of the feeding material, the feeding speed of the feeding machine is effectively controlled, thereby accurately controlling the production quality parameters. The above patent provides a feeding machine that can perform automatic weighing. When the height of the material in the weighing retention bin is too high, the material discharge valve can be automatically closed to prevent excessive accumulation of materials in the weighing retention bin from causing inaccurate weighing. By controlling the weight of the feeding material, the feeding speed of the feeding machine is effectively controlled.

[0004] In the prior art, a utility model patent with the patent number CN201721440792.X discloses a reaction kettle sealing feeding device for VD2 production, including a feeding device and a reaction kettle. The feeding device includes a closed-position-changing feeding device, which is composed of a position-changing feeding tank, a feeding pipe located on one side of the position-changing feeding tank, a one-way valve located between the position-changing feeding tank and the feeding pipe, and a connecting flange located at the bottom end of the position-changing feeding tank. The other end of the feeding pipe is connected to a feeding device, and the connecting flange is used to dock with the feeding valve of the reaction kettle. Through optimized design, the present utility model facilitates closed feeding, and at the same time, the feeding is continuous and stable, and it is convenient to use. The above patent provides a feeding machine that can perform automatic weighing. At the connection between the feeding auger and the reaction kettle, a sealed position-changing feeding device is provided to facilitate closed feeding with the reaction kettle.

[0005] However, in the existing feeding device, when feeding, it is still necessary to manually transport the materials to the feeding equipment of the feeding machine before they can be transported by the feeding auger, resulting in low automation.

[0030] The following will be further described in conjunction with the drawings and specific embodiments:

[0031] Embodiment 1

[0032] As Figure 1 、 Figure 2 and Figure 3As shown in the figure, a tipping metering and feeding device for a reactor includes a feed bin 1, a feeding auger 2, a weighing device 4, a reactor 6, and a raw material barrel 9. It also includes a tipping mechanism 7 and a tipping frame 8. At the upper end of the tipping frame 8, a barrel pressing device 10 is arranged in a lifting manner. At the lower end of the barrel pressing device 10, there is a flared pressing seat 1002 that can be inserted into the mouth of the raw material barrel 9. The tipping frame 8 is rotatably installed on the side of the feed bin 1 through the tipping mechanism 7, and the upper end of the barrel pressing device 10 is inserted into the mouth of the feed bin 1 as the tipping frame 8 tips. The feed bin 1 includes a placement rack 101 and a box body 102, and the box body 102 is seated in the placement rack 101. The tipping frame 8 is rotatably installed on the side of the placement rack 101, and a pair of tipping mechanisms 7 are symmetrically arranged on the two adjacent sides of the placement rack 101 and the tipping frame 8. The tipping frame 8 is rotationally arranged through the tipping mechanism 7. The raw material barrel 9 adopts a barrel structure with an end cover. During use, the end cover can be opened for a short time. Then, after placing the raw material barrel 9 on the tipping frame 8, the barrel pressing device 10 is assembled on the mouth of the raw material barrel 9. Thus, the raw material barrel 9 can be driven by the tipping frame 8 to tip, and the upper port of the barrel pressing device 10 is inserted into the mouth of the feed bin 1. Therefore, the raw material barrel 9 can be automatically filled with raw materials into the feed bin 1 by the tipping frame 8. When the barrel pressing device 10 abuts against the raw material barrel 9 and drives the raw material barrel 9 to tip, it can be compacted and sealed with the port of the raw material barrel 9, thereby preventing the raw materials inside the raw material barrel 9 from being damaged due to long-term contact with air. The raw material barrel 9 adopts a barrel of specific size and material, which can ensure accurate docking with the barrel pressing device 10, and ensure that there is no leakage at the docking part of the raw material barrel 9 and the barrel pressing device 10 when the raw material barrel 9 tips through the tipping frame 8.

[0033] As Figure 1 and Figure 2 shown in the figure, the tipping 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 installed on the placement rack 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 installed on the frame body of the tipping frame 8. The tipping mechanism 7 drives the first connecting rod 701 to rotate through the second electric telescopic rod 702. During the rotation process 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 tipping frame 8 is rotatably installed on the feed bin 1, the tipping frame 8 can be driven to tip around its rotationally installed position through the first connecting rod 701 and the second connecting rod 703. One end of the second electric telescopic rod 702 is rotatably installed on the placement rack 101, and the other end is rotatably installed on the rod body of the first connecting rod 701.

[0034] As Figure 1 and Figure 2As shown, the tipping frame 8 includes a back plate 802. One end of the second connecting rod 703 away from the first connecting rod 701 is rotatably installed on the side of the back plate 802, so as to push the tipping frame 8 to tip. An installation rod 801 is provided at the upper end of the back plate 802, and a pair of side plates 803 are symmetrically arranged on both sides. A plurality of translation rollers 804 are arranged in parallel at the lower ends of the pair of side plates 803; a rotating seat 103 is provided on one side of the upper end of the placement rack 101 close to the tipping frame 8, and the installation rod 801 is rotatably installed 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 pipeline plug 1001; a flared seat 1002 is provided at the lower end of the fixed pipeline plug 1001; a second motor 1003 is provided on the side of the fixed pipeline plug 1001, and the output shaft of the second motor 1003 extends into the fixed pipeline plug 1001 and is provided with a switching plate 1004. A second motor 1003 is provided on the side of the fixed pipeline plug 1001, and the output shaft of the second motor 1003 extends into the fixed pipeline plug 1001 and is provided with a switching plate 1004; by providing the switching plate 1004 and rotating it through the second motor 1003, the fixed pipeline plug 1001 can be closed and opened, so that when the tipping frame 8 is not tipped, the raw material barrel 9 can be blocked by closing the switching plate 1004, and when the tipping is completed, the raw materials in the raw material barrel 9 can be put into the feed box 1 by opening the switching plate 1004.

[0035] As Figures 3 - 5As shown in the figure, a pair of lifting connecting rods 1005 are symmetrically arranged at the position of the side plate 803 corresponding to the side of the fixed pipe plug 1001. A pair of lifting connecting rods 1005 respectively penetrate through the side plate 803 on the same side and are connected with a hydraulic lifting column 1006. Sliding grooves 805 are provided on the side plates of the turnover frame 8 corresponding to the positions of the respective lifting connecting rods 1005. The lifting connecting rods 1005 penetrate through the sliding grooves 805 and are connected with the hydraulic lifting columns 1006. The hydraulic lifting column 1006 can drive the fixed pipe plug 1001 to perform lifting operations, so that the flared mouth pressure seat 1002 can be controlled to descend and abut against the mouth of the raw material barrel 9. And the flared mouth pressure seat 1002 is sleeved on the outer side of the mouth of the raw material barrel 9. At the same time, a sealing table adapted to the end face of the mouth of the raw material barrel 9 is provided inside the flared mouth pressure seat 1002, and a sealing gasket is arranged on the sealing table, 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 arranged on the side plate 803. The first clamping plates 11 of the pair of side plates 803 are clamped against the barrel body of the raw material barrel 9 relatively. The second clamping plates 12 of the pair of side plates 803 are clamped against the joint of the raw material barrel 9 and the flared mouth pressure seat 1002 relatively. The first clamping plate 11 includes a first hydraulic telescopic column 1101. The first hydraulic telescopic column 1101 is arranged on the side plate 803. The first clamping plate 11 is clamped on the raw material barrel 9 through the first hydraulic telescopic column 1101. The second clamping plate 12 includes a second hydraulic telescopic column 1201. The second hydraulic telescopic column 1201 is arranged on the side plate 803. The second clamping plate 12 is clamped against the joint of the raw material barrel 9 and the flared mouth pressure seat 1002 through the second hydraulic telescopic column 1201. When the raw material barrel 9 is placed on the translation roller 804, then the first hydraulic telescopic column 1101 on the two side plates 803 can be used to control the first clamping plate 11 to clamp on the barrel body of the raw material barrel 9, so as to clamp the raw material barrel 9 and prevent the raw material barrel 9 from shaking. At the same time, the second hydraulic telescopic column 1201 can be used to control the second clamping plate 12 to clamp against the joint of the raw material barrel 9 and the flared mouth pressure seat 1002, which can not only enhance the bonding strength of the joint of the raw material barrel 9 and the flared mouth pressure seat 1002, but also further increase the sealing strength.

[0036] As Figure 1 and Figures 6 - 8As shown in the figure, the lower end of the feeding auger 2 is connected to the feed bin 1, and the upper end is arranged above the weighing device 4. The lower end of the weighing device 4 is provided with a material distributing device 5, and the lower end of the material distributing device 5 is provided with a discharge cloth tube 505 extending into the reaction kettle 6. Inside the feeding auger 2, the material is lifted by the spiral auger, and the material is conveyed from the feed bin 1 to the weighing device 4 above. Additionally, there is a fixing frame 3. The weighing device 4 is arranged above the reaction kettle 6 through the fixing frame 3. The weighing device 4 includes a weighing funnel 401 and a gravity sensor 402. An installation edge 403 extends from the upper end side of the weighing funnel 401. Support legs 404 are arranged at the four corners of the bottom of the installation edge 403, and gravity sensors 402 are arranged at the bottoms of the support legs 404. The weighing funnel 401 is mounted on the fixing frame 3 through the gravity sensors 402; a material distributing device 5 is arranged at the lower port of the weighing funnel 401. The weighing device 4 weighs the material through the gravity sensors 402. Through multiple experiments and calculations, the accuracy of the gravity sensors 402 in weighing the material in the weighing funnel 401 is ensured. When the material is conveyed to the weighing device 4, the weight of the weighing funnel 401 can be detected in real time through the gravity sensors 402. The material distributing device 5 includes a first motor 501 and a first electric telescopic rod 503. In the material distributing device 5, a distributing roller 502 is rotatably arranged through the first motor 501. A plurality of distributing grooves 506 are successively formed along the circumferential direction of the distributing roller 502. The lower end of the material distributing device 5 is provided with a discharge cloth tube 505; a first electric telescopic rod 503 is arranged on the side of the material distributing device 5 corresponding to the position of the lowest distributing groove 506, and a wiping head 504 adapted to the distributing groove 506 is arranged at the telescopic end of the first electric telescopic rod 503. The material distributing device 5 is fixedly arranged at the lower end of the weighing device 4 through a steel frame, and the weighing of the gravity sensors 402 subtracts the weights of the material distributing device 5 and the weighing funnel 401 itself. At the same time, by arranging the discharge cloth tube 505 at the lower end of the material distributing device 5, the weighing device 4 can be supported on the fixing frame 3 only by the gravity sensors 402, and there is no additional force in the up and down positions, thus ensuring the accuracy of the weighing device 4. The first motor 501 in the material distributing device 5 is programmed and controlled by an external control device to rotate intermittently, so that each distributing groove 506 can gradually drive the raw materials in the weighing funnel 401, and when the distributing groove 506 rotates to the position of the discharge cloth tube 505, the raw materials are put into the reaction kettle 6. At the same time, during the intermittent gap of the first motor 501, the first electric telescopic rod 503 will drive the wiping head 504 to extend into the lowest distributing groove 506 through the external control device to wipe it, preventing raw materials from adhering to its inside. And the first motor 501 and the first electric telescopic rod 503 are programmed and controlled by an external control device to stagger their operations so that there is no interference between the distributing roller 502 and the wiping head 504.The material distribution device 5 is provided with a through hole adapted to the wiping head 504 on the side corresponding to the wiping head 504. When the wiping head 504 is not performing wiping work, the end close to the material distribution groove 506 stays in the through hole, which can block the outer shell of the material distribution device 5 and prevent materials from leaking out through the through hole. When work is required, the wiping head 504 is driven by the first electric telescopic rod 503 to extend into the lowermost material distribution groove 506 for wiping. After wiping, it will return to the state of blocking the through hole again without affecting the normal rotation of the material distribution roller 502.

The lower end of the weighing device 4 is provided with a material distributing device 5, and the lower end of the material distributing device 5 is provided with a discharge cloth tube 505 extending into the reaction kettle 6. In addition, a fixing frame 3 is also included. The weighing device 4 is arranged above the reaction kettle 6 through the fixing frame 3. The weighing device 4 includes a weighing funnel 401 and a gravity sensor 402. The upper end side of the weighing funnel 401 extends to be provided with a mounting edge 403. The four corners of the bottom of the mounting edge 403 are provided with support legs 404, and the bottom of the support legs 404 is provided with a gravity sensor 402. The weighing funnel 401 is mounted on the fixing frame 3 through the gravity sensor 402; the lower port of the weighing funnel 401 is provided with a material distributing device 5. The material distributing device 5 includes a first motor 501 and a first electric telescopic rod 503. In the material distributing device 5, a material distributing roller 502 is rotatably arranged through the first motor 501. A plurality of material distributing grooves 506 are sequentially arranged on the material distributing roller 502 along the circumferential direction thereof. The lower end of the material distributing device 5 is provided with a discharge cloth tube 505; a first electric telescopic rod 503 is arranged at the position of the side surface of the material distributing device 5 corresponding to the lowest material distributing groove 506, and a wiping head 504 adapted to the material distributing groove 506 is arranged on the telescopic end of the first electric telescopic rod 503.

[0042] The working principle of the present invention: 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 turning frame 8 to turn, so that the raw material barrel 9 is communicated with the feed bin 1 through the barrel pressing device 10. Then, by controlling the second motor 1003 to drive the opening and closing plate 1004 to rotate, the raw materials inside the raw material barrel 9 can be put into the feed bin 1. The raw materials are conveyed to the weighing device 4 by the feeding auger 2. The weight of the fed raw materials is detected by the gravity sensor 402. After the specified weight of raw materials is fed, the first motor 501 is controlled to drive the material distributing roller 502 to rotate intermittently, and the raw materials are gradually put into the reaction kettle 6. Along with the intermittent gap of the first motor 501, the first electric telescopic rod 503 will drive the wiping head 504 to extend into the lowest material distributing groove 506 through an external control device for wiping to prevent raw materials from adhering to the inside thereof.

[0043] In summary, in the present invention, by arranging a turnover rack 8 driven by a turnover mechanism 7 on the side of the material box 1, the raw material barrel 9 can be automatically driven to turn over into the material box 1 for feeding. Only the raw material barrel needs to be placed on the turnover rack 8 manually, which effectively reduces the workload of employees for feeding. At the same time, through the automatic turnover and feeding by the turnover rack 8, the problem of material spilling caused by improper manual operation is avoided. By arranging a material distribution device 5, the weighed raw materials in the weighing device 4 can be gradually fed into the reaction kettle 6, and through the staggered operation of the first motor and the first electric telescopic rod 503, the lowermost material distribution groove 506 can be cleaned in time to avoid the agglomeration of raw materials in the material distribution groove 506 and improve the service life of the material distribution device 5.
