Abstract
Description
Technical Field
[0001] This utility model relates to the field of polymerization inhibitor technology, and in particular to an automatic polymerization inhibitor feeding device. Background Technology
[0002] Polymerization inhibitors are industrial additives primarily used to prevent polymerization reactions of olefin monomers during production, storage, and transportation. They terminate the polymerization chain reaction by reacting with free radicals in the system to form non-free radical substances or low-reactivity free radicals. In chemical production, the addition of polymerization inhibitors is a crucial process step, aiming to prevent accidental polymerization caused by the accumulation of free radicals during the polymerization reaction, thereby ensuring the stability and safety of the production process.
[0003] Traditionally, the addition of polymerization inhibitors relies on manual pouring into the reaction vessel. However, manual addition often results in uneven distribution of the inhibitor, affecting the entire chemical production process and leading to a decline in product quality. Therefore, how to achieve more uniform addition of polymerization inhibitors is a crucial issue that needs to be addressed in the design of automated polymerization inhibitor feeding devices. Utility Model Content
[0004] This invention provides an automatic polymerization inhibitor feeding device to solve the problem of uneven feeding of polymerization inhibitors.
[0005] This utility model solves the above-mentioned technical problems through the following technical solutions:
[0006] This utility model provides an automatic polymerization inhibitor feeding device, including a polymerization inhibitor feeding shell, and further comprising:
[0007] A rotating feeding structure is disposed inside the polymerization inhibitor feeding shell;
[0008] A material conveying structure is provided on a rotating feeding structure, and the rotating feeding structure drives the material conveying structure to rotate and feed materials.
[0009] Preferably, two fixing rings are fixedly connected to the top and bottom of the inner sidewall of the polymerization inhibitor feeding shell, and the top sidewall of the fixing ring at the bottom of the polymerization inhibitor feeding shell is inclined towards the middle.
[0010] In this technical solution, the inclined sidewall at the top of the fixing ring guides the polymerization inhibitor toward the center.
[0011] Preferably, a feed pipe is fixedly connected to the side wall of the polymerization inhibitor feeding shell, a feed funnel is fixedly connected to the top of the feed pipe, a cover plate is rotatably connected to the top of the feed funnel, and a handle is fixedly connected to the top side wall of the cover plate.
[0012] In this technical solution, the cover is opened by the handle, and the polymerization inhibitor to be added is poured into the feed funnel. The polymerization inhibitor enters the polymerization inhibitor feeding shell through the feed pipe.
[0013] Preferably, the rotating feeding structure includes a fixed frame, a feeding guide frame one, a feeding guide frame two, a feeding pipe, a rotating rod, a motor, and a supporting circular plate. The fixed frame is fixedly connected to the top side wall of the fixed ring frame above the polymerization inhibitor feeding shell. A motor is fixedly connected to the top inner side wall of the fixed frame. The rotating end of the motor is fixedly connected to the rotating rod. Two supporting circular plates are fixedly connected to the side wall of the rotating rod. The two supporting circular plates are rotatably connected within the two fixed ring frames. Two feeding pipes are fixedly connected to the side wall of the supporting circular plate below the rotating rod. The bottom of the two feeding pipes are respectively fixedly connected to the feeding guide frame one and the feeding guide frame two.
[0014] In this technical solution, the polymerization inhibitor falls onto feeding guide frame one and feeding guide frame two through the feeding pipe. The polymerization inhibitor slides down along the inclined side walls of feeding guide frame one and feeding guide frame two. The motor rotates, which drives the rotating rod to rotate. The rotating rod drives the supporting circular plate to rotate. The supporting circular plate drives the feeding pipe to rotate. The feeding pipe drives feeding guide frame one and feeding guide frame two to rotate to feed the material, thus ensuring that the polymerization inhibitor is fed evenly.
[0015] Preferably, the length of the second feeding guide is half that of the first feeding guide, the first feeding guide and the second feeding guide are in opposite directions, and both the first feeding guide and the second feeding guide are inclined downwards.
[0016] In this technical solution, feeding guide frame one guides the polymerization inhibitor to a longer distance, while feeding guide frame two guides the polymerization inhibitor to a shorter distance.
[0017] Preferably, heat dissipation grooves are provided at equal intervals on the side wall of the fixing frame, and a dustproof net is fixedly connected to the inner side wall of the heat dissipation groove.
[0018] In this technical solution, the heat dissipation groove effectively dissipates heat from the inside of the mounting bracket, while the dustproof mesh prevents dust from entering the mounting bracket.
[0019] Preferably, the inner sidewalls of the fixing frame and the fixing ring frame are provided with annular rotating tooth grooves.
[0020] Preferably, a guide block is fixedly connected to the top side wall of the support circular plate below the rotating rod, and the side wall of the guide block is inclined toward the feed pipes on both sides.
[0021] In this technical solution, the guide block guides the polymerization inhibitor in the polymerization inhibitor feeding shell to the two feeding pipes.
[0022] Preferably, the sidewalls at both ends of the guide block are in contact with the inner sidewall of the lower fixing ring frame, and the highest point of the guide block and the lower fixing ring frame are at the same height.
[0023] Preferably, the material conveying structure includes a rotating gear, a connecting block, and a material conveying screw. The connecting block is rotatably connected to the side wall of a supporting circular plate above the rotating rod. The rotating gear is fixedly connected to the top side wall of the connecting block, and the material conveying screw is fixedly connected to the bottom side wall of the connecting block. The bottom of the material conveying screw extends into the feed pipe, and the rotating gear meshes with the rotating tooth groove.
[0024] In this technical solution, the connecting block drives the rotating gear and the feeding screw to rotate around the rotating rod. The rotating gear rotates within the rotating tooth groove and rotates on its own axis. The rotation of the rotating gear drives the connecting block to rotate on its own axis, and the connecting block drives the feeding screw to rotate on its own axis. The rotation of the feeding screw conveys the polymerization inhibitor in the feeding shell downwards, preventing the polymerization inhibitor from remaining in the feeding pipe.
[0025] Based on common knowledge in the field, the above-mentioned preferred conditions can be combined arbitrarily to obtain various preferred embodiments of this utility model.
[0026] The positive and progressive effects of this utility model are as follows:
[0027] 1. In this application, the polymerization inhibitor slides downward along the side walls of the inclined feeding guide frame 1 and feeding guide frame 2 for feeding. Feeding guide frame 1 guides the polymerization inhibitor a longer feeding distance, while feeding guide frame 2 guides the polymerization inhibitor a shorter feeding distance. The motor rotates, driving the rotating rod to rotate, which in turn drives feeding guide frame 1 and feeding guide frame 2 to rotate for feeding, thus facilitating better and more uniform feeding of the polymerization inhibitor.
[0028] 2. As the supporting circular plate above rotates, the connecting block rotates, causing the rotating gear and the feeding screw to rotate around the rotating rod. The rotating gear rotates within the rotating tooth groove, causing it to rotate on its own axis. This rotation of the rotating gear drives the feeding screw to rotate on its own axis, which in turn conveys the polymerization inhibitor in the feeding housing downwards. This prevents the polymerization inhibitor from remaining in the feeding pipe, thus facilitating the downward feeding of the polymerization inhibitor while avoiding blockage of the feeding pipe.

[0036] A rotating feeding structure 7 is disposed inside the polymerization inhibitor feeding housing 1;
[0037] The material conveying structure 10 is mounted on the rotating feeding structure 7. The rotating feeding structure 7 rotates to drive the material conveying structure 10 to rotate and feed materials.
[0038] Two fixing rings 6 are fixedly connected to the top and bottom of the inner sidewall of the polymer inhibitor feeding housing 1, and the top sidewall of the fixing ring 6 below the polymer inhibitor feeding housing 1 is inclined towards the middle.
[0039] The inclined sidewall at the top of the fixed ring 6 guides the polymerization inhibitor toward the center.

[0041] Open the cover plate 4 by using the handle 5, pour the required polymerization inhibitor into the feed funnel 3, and the polymerization inhibitor enters the polymerization inhibitor feeding shell 1 through the feed pipe 2.
[0042] The rotating feeding structure 7 includes a fixed frame 701, a feeding guide frame one 702, a feeding guide frame two 703, a feeding pipe 704, a rotating rod 705, a motor 706, and a supporting circular plate 707. The fixed frame 701 is fixedly connected to the top side wall of the fixed ring frame 6 above the polymerization inhibitor feeding housing 1. The motor 706 is fixedly connected to the top inner side wall of the fixed frame 701. The rotating end of the motor 706 is fixedly connected to the rotating rod 705. Two supporting circular plates 707 are fixedly connected to the side wall of the rotating rod 705. The two supporting circular plates 707 are rotatably connected to the two fixed ring frames 6. Two feeding pipes 704 are fixedly connected to the side wall of the supporting circular plate 707 below the rotating rod 705. The bottom of the two feeding pipes 704 are respectively fixedly connected to the feeding guide frame one 702 and the feeding guide frame two 703.
[0043] The polymerization inhibitor falls through the feeding pipe 704 onto the feeding guide frame 702 and the feeding guide frame 703. The polymerization inhibitor slides down along the inclined side walls of the feeding guide frame 702 and the feeding guide frame 703. The motor 706 rotates, driving the rotating rod 705 to rotate. The rotating rod 705 drives the supporting circular plate 707 to rotate. The supporting circular plate 707 drives the feeding pipe 704 to rotate. The feeding pipe 704 drives the feeding guide frame 702 and the feeding guide frame 703 to rotate for feeding, thus ensuring that the polymerization inhibitor is fed evenly.
[0044] The length of the second feeding guide 703 is half that of the first feeding guide 702. The directions of the first feeding guide 702 and the second feeding guide 703 are opposite to each other. Both the first feeding guide 702 and the second feeding guide 703 are inclined downwards.
[0045] Feeding guide frame 1 702 guides the polymerization inhibitor to a longer feeding distance, while feeding guide frame 2 703 guides the polymerization inhibitor to a shorter feeding distance.
[0046] The side wall of the fixed frame 701 is provided with heat dissipation grooves 8 at equal intervals, and a dustproof net 9 is fixedly connected to the inner side wall of the heat dissipation groove 8.
[0047] The heat dissipation slot 8 effectively dissipates heat from the inside of the mounting bracket 701, while the dustproof mesh 9 prevents dust from entering the mounting bracket 701.
[0048] The inner sidewalls of the fixing frame 701 and the fixing ring frame 6 are provided with annular rotating tooth grooves 12.
[0049] A guide block 11 is fixedly connected to the top side wall of the support circular plate 707 below the rotating rod 705. The side wall of the guide block 11 is inclined towards the feed pipes 704 on both sides.
[0050] The guide block 11 guides the polymerization inhibitor in the polymerization inhibitor feeding shell 1 to the two feed pipes 704.
[0051] The sidewalls at both ends of the guide block 11 are in contact with the inner sidewall of the lower fixing ring 6, and the highest point of the guide block 11 and the lower fixing ring 6 are at the same height.
[0052] The material conveying structure 10 includes a rotating gear 1001, a connecting block 1002, and a material conveying screw 1003. The connecting block 1002 is rotatably connected to the side wall of the support circular plate 707 above the rotating rod 705. The rotating gear 1001 is fixedly connected to the top side wall of the connecting block 1002, and the material conveying screw 1003 is fixedly connected to the bottom side wall of the connecting block 1002.

[0053] The connecting block 1002 drives the rotating gear 1001 and the feeding screw to rotate around the rotating rod 705. The rotating gear 1001 rotates within the rotating tooth groove 12 and rotates on its own axis. The rotation of the rotating gear 1001 drives the connecting block 1002 to rotate on its own axis. The connecting block 1002 drives the feeding screw 1003 to rotate on its own axis. The rotation of the feeding screw conveys the polymerization inhibitor in the polymerization inhibitor feeding housing 1 downwards, preventing the polymerization inhibitor from remaining in the feeding pipe 704.
[0054] In use, all electrical components mentioned in this application are externally connected to a power supply and control switch. The feeding device is installed on the equipment that needs to be fed. Feeding guide frame 1 702 and feeding guide frame 2 703 extend into the equipment. The cover plate 4 is opened by the handle 5, and the polymerization inhibitor to be added is poured into the feeding funnel 3. The polymerization inhibitor enters the polymerization inhibitor feeding shell 1 through the feeding pipe 2. The inclined side wall of the top of the fixing ring frame 6 and the guide block 11 guide the polymerization inhibitor in the polymerization inhibitor feeding shell 1 to the two discharge pipes 704. The polymerization inhibitor falls onto feeding guide frame 1 702 and feeding guide frame 2 703 through the discharge pipes 704. The polymerization inhibitor slides down along the inclined side wall of feeding guide frame 1 702 and feeding guide frame 2 703. Feeding guide frame 1 702 guides the polymerization inhibitor a longer feeding distance, while feeding guide frame 2 703 guides the polymerization inhibitor a shorter feeding distance.
[0055] The rotation of motor 706 drives the rotation rod 705 to rotate, which in turn drives the support circular plate 707 to rotate. The support circular plate 707 drives the feeding pipe 704 to rotate, which in turn drives the feeding guide frame 1 702 and the feeding guide frame 2 703 to rotate for feeding, facilitating the uniform feeding of the polymerization inhibitor. The connecting block 1002 rotates along with the rotation of the support circular plate 707 above. The connecting block 1002 drives the rotating gear 1001 and the feeding screw rod to rotate around the rotation rod 705. The rotating gear 1001 rotates within the rotating tooth groove 12 and rotates on its own axis. The rotation of the rotating gear 1001 drives the connecting block 1002 to rotate on its own axis, which in turn drives the feeding screw rod 1003 to rotate on its own axis. The rotation of the feeding screw rod conveys the polymerization inhibitor in the polymerization inhibitor feeding housing 1 downwards, preventing the polymerization inhibitor from remaining in the feeding pipe 704. This facilitates the downward feeding of the polymerization inhibitor while preventing blockage of the feeding pipe 704.
