Description

A quantitative feeding device for the synthesis of organic polymers Technical Field

[0001] This utility model relates to the technical field of organic polymer synthesis, specifically to a quantitative feeding device for organic polymer synthesis. Background Technology

[0002] Organic polymer materials, also known as polymers or high-polymer materials, are macromolecules composed primarily of high-molecular compounds, combined with various additives (or compounding agents), and processed appropriately. They are a class of macromolecules with multiple repeating monomer units, formed by one or more molecules or molecular groups linked by covalent bonds, with molecular weights ranging from 10⁴ to 10⁶. They can be natural products such as fibers, proteins, and natural rubber, or synthesized through synthetic methods, such as synthetic rubber, synthetic resins, and synthetic fibers—non-biological polymers. Polymers are characterized by their versatility, low density (only 1 / 7 to 1 / 8 that of steel), high specific strength, good electrical insulation and corrosion resistance, and ease of processing. They can meet the requirements of various special applications, including plastics, fibers, rubber, coatings, and adhesives, and can partially replace metallic and non-metallic materials.

[0003] Publication number "CN222287305U" discloses a quantitative feeding device for organic polymer synthesis, including a mixing cylinder, a stirring frame, a driving component, an air jetting component, and an air pump. The stirring frame is rotatably mounted inside the mixing cylinder; the driving component drives the stirring frame to rotate; the air jetting component is mounted on the stirring frame and is used to spray high-pressure gas onto the inner wall of the mixing cylinder; and a gas source is provided to the air jetting component. This invention, by incorporating the air jetting component and air pump, can clean the raw materials adhering to the inner wall of the mixing cylinder, reducing the deviation in the proportion of raw materials finally poured into the reactor, and effectively improving the quality of the final synthesized organic polymer material.

[0004] However, the above-mentioned device still has the following problems during implementation:

[0005] In the processing of organic polymers, the required material particles need to be added to the reactor through a hopper, and then synthesized by heating and stirring. However, the existing feeding method usually involves adding all the materials directly into the reactor. This one-time adjustment method can easily lead to material accumulation, which in turn affects the synthesis effect. Summary of the Invention

[0006] The purpose of this invention is to provide a quantitative feeding device for the synthesis of organic polymers, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A quantitative feeding device for organic polymer synthesis includes a reaction vessel, a hopper, and a feeding pipe. The feeding pipe is fixedly connected to the bottom of the hopper, and one end of the feeding pipe is fixedly connected to one side of the reaction vessel. A spherical baffle is provided inside the feeding pipe, and a feeding hole is opened on one side of the spherical baffle. A support frame is fixedly connected to one side of the reaction vessel, and a transmission mechanism for controlling the quantitative feeding of the feeding pipe is provided on the top of the support frame.

[0009] An air collecting mechanism is fixedly mounted on a support frame and can spray air into the feed pipe while the transmission mechanism is running.

[0010] Preferably, the transmission mechanism includes a motor fixedly installed on the top of the support frame, a first transmission wheel fixedly connected to the output end of the motor, a transmission rod fixedly connected to one side of the spherical block, one end of the transmission rod extending through to one side of the feed pipe and fixedly connected to a second transmission wheel, and the first transmission wheel and the second transmission wheel being connected by a belt drive.

[0011] Preferably, the gas collection mechanism includes a gas collection box fixedly connected to the top of the support frame. An air inlet pipe is fixedly connected to the top of the gas collection box. Air jet pipes are fixedly connected to both sides of the gas collection box. One end of the air jet pipe is fixedly connected to one end of the feed pipe. A lead screw is fixedly connected to one side of the first transmission wheel. A transmission block is drivenly connected to the surface of the lead screw. A push rod is fixedly connected to one side of the transmission block. One end of the push rod penetrates into the interior of the gas collection box and is fixedly connected to the push block.

[0012] Preferably, a sliding block is fixedly connected to the bottom of the transmission block, and a sliding groove is provided on the top of the support frame to cooperate with the sliding block.

[0013] Preferably, a one-way valve is fixedly installed on the surface of the air intake pipe, and a one-way pressure valve is fixedly installed on the surface of the jet pipe.

[0014] Preferably, a piston plate is fixedly connected to one side of the push block, and the piston plate is made of rubber.

[0015] Preferably, a bearing is provided on one side of the second transmission wheel, and the bearing is rotatably connected to one side of the feed tube.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This utility model, by setting up a transmission mechanism, enables material particles to be placed inside the hopper. After starting the motor, the motor drives the first transmission wheel to rotate, which in turn drives the second transmission wheel to rotate via a belt. As the second transmission wheel rotates, it drives the transmission rod and the spherical stop block to rotate around the bearing. When the spherical stop block rotates to the position where the discharge hole faces upward, the material in the hopper will pass through the discharge hole and then enter the hopper through the discharge pipe. When the spherical stop block rotates to other positions, no material will be discharged. This cycle is repeated to achieve intermittent quantitative feeding, avoid material accumulation, and thus improve the synthesis effect.

[0018] 2. This utility model, by setting up a gas collection mechanism, can drive the lead screw to rotate while the second transmission wheel rotates. The rotation of the lead screw will drive the transmission block, causing the transmission block to move back and forth left and right. When the transmission block moves to the left, the push rod, push block and piston plate will move to the left simultaneously. At this time, the gas collection box is under negative pressure, and the gas will enter the interior of the gas collection box through the air inlet pipe. Then, when the transmission block drives the push rod, push block and piston plate to move to the right, it will compress the fixed gas in the gas collection box. When the gas pressure is higher than the limit of the one-way pressure valve, the gas will be ejected from the jet pipe. This cycle continues. Under the action of intermittent jetting from the jet pipe, the material particles in the feed pipe will change their falling position under the push of the airflow, avoiding the accumulation of material particles and further improving the synthesis effect.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please refer to Figures 1-5. This utility model provides a technical solution:

[0027] Example 1:

[0028] A quantitative feeding device for organic polymer synthesis includes a reactor 1, a hopper 2, and a feeding pipe 3. The feeding pipe 3 is fixedly connected to the bottom of the hopper 2, and one end of the feeding pipe 3 is fixedly connected to one side of the reactor 1. A spherical baffle 4 is provided inside the feeding pipe 3, and a feeding hole 5 is opened on one side of the spherical baffle 4. A support frame 6 is fixedly connected to one side of the reactor 1, and a transmission mechanism for controlling the quantitative feeding of the feeding pipe 3 is provided on the top of the support frame 6.

[0029] The air collection mechanism is fixedly mounted on the support frame 6 and can spray air into the downward material pipe 3 while the transmission mechanism is running.

[0030] The transmission mechanism includes a motor 7 fixedly installed on the top of the support frame 6. The output end of the motor 7 is fixedly connected to a first transmission wheel 8. A transmission rod 9 is fixedly connected to one side of the spherical block 4. One end of the transmission rod 9 extends through to one side of the feed pipe 3 and is fixedly connected to a second transmission wheel 10. The first transmission wheel 8 and the second transmission wheel 10 are connected by a belt 11.

[0031] In this embodiment, by setting up a transmission mechanism, after the material particles are placed inside the hopper 2, the motor 7 is started, which drives the first transmission wheel 8 to rotate. The first transmission wheel 8 then drives the second transmission wheel 10 to rotate via the belt 11. As the second transmission wheel 10 rotates, it drives the transmission rod 9 and the spherical stop 4 to rotate around the bearing 24. When the spherical stop 4 rotates to the position where the discharge hole 5 faces upward, the material in the hopper 2 will pass through the discharge hole 5 and then enter the hopper 2 through the discharge pipe 3. When the spherical stop 4 rotates to other positions, no material will be discharged. This cycle is repeated to achieve intermittent quantitative feeding, avoid material accumulation, and thus improve the synthesis effect.

[0032] A bearing 24 is provided on one side of the second transmission wheel 10, and is rotatably connected to one side of the feed tube 3 through the bearing 24.

[0033] In this embodiment, by setting the bearing 24, the transmission rod 9 and the spherical stop block 4 can be supported, while restricting them to rotate only around the bearing 24, thus improving the smoothness of their rotation.

[0034] Example 2:

[0035] Based on Embodiment 1, in this embodiment, the transmission mechanism can control the spherical stop 4 to rotate, thereby achieving intermittent quantitative feeding. However, considering that if the material particles always remain at the same position when falling into the reactor 1, they are prone to accumulation, the gas collection mechanism in this application includes a gas collection box 12 fixedly connected to the top of the support frame 6. The top of the gas collection box 12 is fixedly connected to an air inlet pipe 13, and both sides of the gas collection box 12 are fixedly connected to jet pipes 14. One end of the jet pipe 14 is fixedly connected to one end of the feeding pipe 3. A lead screw 15 is fixedly connected to one side of the first transmission wheel 8, and a transmission block 16 is drivenly connected to the surface of the lead screw 15. A push rod 17 is fixedly connected to one side of the transmission block 16, and one end of the push rod 17 penetrates into the interior of the gas collection box 12 and is fixedly connected to a push block 18.

[0036] In this embodiment, by setting up a gas collection mechanism, the second transmission wheel 10 can rotate while driving the lead screw 15 to rotate. The rotation of the lead screw 15 will drive the transmission block 16, causing the transmission block 16 to move back and forth. Referring to Figure 4, when the transmission block 16 moves to the left, the push rod 17, the push block 18, and the piston plate 23 will move to the left simultaneously. At this time, the gas collection box 12 is under negative pressure, and the gas will enter the interior of the gas collection box 12 through the air inlet pipe 13. Then, when the transmission block 16 drives the push rod 17, the push block 18, and the piston plate 23 to move to the right, it will compress the fixed gas in the gas collection box 12. When the gas pressure is higher than the limit of the one-way pressure valve 22, the gas will be ejected from the jet pipe 14. This cycle continues. Under the intermittent jet action of the jet pipe 14, the material particles in the feed pipe 3 will change their falling position under the push of the airflow, avoiding the accumulation of material particles and further improving the synthesis effect.

[0037] A sliding block 19 is fixedly connected to the bottom of the transmission block 16, and a sliding groove 20 that cooperates with the sliding block 19 is provided on the top of the support frame 6.

[0038] In this embodiment, by setting the sliding block 19 and the sliding groove 20, when the lead screw 15 drives the transmission block 16, the transmission block 16 can only reciprocate under the restriction of the sliding block 19 and the sliding groove 20.

[0039] A one-way valve 21 is fixedly installed on the surface of the air intake pipe 13, and a one-way pressure valve 22 is fixedly installed on the surface of the jet pipe 14.

[0040] In this embodiment, a one-way valve 21 and a one-way pressure valve 22 are provided. The one-way valve 21 is a valve that allows air to enter the gas collection box 12, and the one-way pressure valve 22 is a valve that allows air to be discharged into the feed pipe 3. Therefore, when the gas collection box 12 is under negative pressure, the gas can only enter the gas collection box 12 through the air inlet pipe 13. When the gas in the gas collection box 12 is compressed, the gas can only be discharged into the feed pipe 3 through the jet pipe 14.

[0041] A piston plate 23 is fixedly connected to one side of the push block 18. The piston plate 23 is made of rubber.

[0042] In this embodiment, by setting the piston plate 23, the sealing performance of the air collection box 12 can be improved, so as to facilitate the process of air collection and jetting.

[0043] Working principle: After placing the material particles into the hopper 2, the user starts the motor 7, which drives the first transmission wheel 8 to rotate. The first transmission wheel 8 then drives the second transmission wheel 10 to rotate via the belt 11. As the second transmission wheel 10 rotates, it drives the transmission rod 9 and the spherical stop 4 to rotate around the bearing 24. When the spherical stop 4 rotates to the point where the discharge hole 5 faces upward, the material in the hopper 2 will pass through the discharge hole 5 and then enter the hopper 2 through the discharge pipe 3. When the spherical stop 4 rotates to other positions, no material will be discharged. This cycle is repeated to achieve intermittent quantitative feeding, avoid material accumulation, and thus improve the synthesis effect.

[0044] While the second transmission wheel 10 rotates, it drives the lead screw 15 to rotate. The rotation of the lead screw 15 drives the transmission block 16, causing the transmission block 16 to move back and forth. Referring to Figure 4, when the transmission block 16 moves to the left, the push rod 17, the push block 18, and the piston plate 23 move to the left simultaneously. At this time, the gas collection box 12 is under negative pressure, and the gas will enter the interior of the gas collection box 12 through the air inlet pipe 13. Then, when the transmission block 16 drives the push rod 17, the push block 18, and the piston plate 23 to move to the right, it will compress the fixed gas in the gas collection box 12. When the gas pressure is higher than the limit of the one-way pressure valve 22, the gas will be ejected from the jet pipe 14. This cycle continues. Under the intermittent jet action of the jet pipe 14, the material particles in the feed pipe 3 will change their falling position under the push of the airflow, avoiding the accumulation of material particles and further improving the synthesis effect.

[0045] It should be noted that the motor 7 is a device or equipment existing in the prior art, or a device or equipment that can be implemented by the prior art, and the specific composition and principle of the power supply of the motor 7 are clear to those skilled in the art, so they will not be described in detail here.

[0046] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
