Description

Technical Field

[0001] This utility model relates to the technical field of feeding devices, and in particular to a feeding device for processing acrylamide monomer polymers. Background Technology

[0002] Acrylamide monomer polymers are generally processed in a reaction vessel, which provides a closed and controllable environment for the polymerization reaction.

[0003] In the processing of acrylamide monomer polymers, in order to ensure the accuracy and stability of the reaction, multiple materials need to be introduced into the reactor at the same time. This is usually done by setting up multiple feed ports to facilitate the simultaneous addition of materials. However, multiple feed ports require multiple people to add materials at the same time. Different materials may not be able to enter the reactor at the same time due to differences in the feeding order and feeding speed, which will affect the accuracy of the reaction and is quite inconvenient.

[0031] 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.

[0032] This utility model provides, for example Figure 1-4 The device shown is a feeding device for processing acrylamide monomer polymers. It includes a reactor 1, with multiple metering tubes 2 fixedly connected at equal intervals to the top of the reactor 1. A feeding mechanism is provided on the reactor 1, which includes a piston plate 3, a connecting plate 4, a fixing rod 5, a sliding ring 6, and a positioning component 7. The piston plate 3 is slidably inserted into the inner cavity of the metering tubes 2. One end of the connecting plate 4 is fixedly connected to the piston plate 3, and the other end of the connecting plate 4 is slidably inserted into the reactor 1. The fixing rod 5 is fixedly connected to the top of the reactor 1. The sliding ring 6 is sleeved on the outside of the fixing rod 5. The other end of the connecting plate 4 is fixedly connected to the sliding ring 6. The positioning component 7 is disposed inside the fixing rod 5. The positioning component 7 limits the position of the sliding ring 6, thereby allowing the piston plate 3 to seal the bottom of the multiple metering tubes 2. Different materials can be added into the multiple metering tubes 2. When the positioning component 7 releases the limit on the sliding ring 6, the materials in each metering tube 2 can enter the reactor 1 simultaneously, solving the problem of asynchronous feeding in the prior art and making it easy to use.

[0033] Specifically, the positioning assembly 7 includes a positioning rod 71, a pressing plate 72, a first compression spring 73, a pressing wheel 74, a rotating rod 75, a pressing block 76, a pressing rod 77, and a second compression spring 78. Multiple positioning grooves are equidistantly formed on the outer wall of the fixing rod 5. The positioning rod 71 is slidably inserted into the inner cavity of the positioning groove. The pressing plate 72 is located inside the positioning groove and is fixedly connected to one end of the positioning rod 71. The first compression spring 73 is sleeved on the outside of the positioning rod 71. One end of the first compression spring 73 is fixedly connected to the pressing plate 72, and the other end is fixedly connected to the inner wall of the positioning groove. The first compression spring 73 provides a stable elastic force to the positioning rod 71 through the pressing plate 72, thereby allowing the pressing plate 72 to closely adhere to the pressing wheel 74 while simultaneously enabling the positioning rod 71 to extend and retract when the pressing wheel 74 rotates. The pressing wheel 74 is rotatably positioned between the pressing plates 72, and its cross-section is elliptical. The rotating rod 75 is connected to the pressing wheel 76. 4. Fixed interlocking connection: The rotating rod 75 is rotatably interlocked with the fixed rod 5 through a bearing. The rotating rod 75 has an extrusion groove inside, and the extrusion block 76 is located inside the extrusion groove. The extrusion rod 77 is fixedly interlocked with the extrusion block 76. The cross-section of the extrusion rod 77 is square. The fixed rod 5 has a square groove inside for engaging the extrusion rod 77. The second compression spring 78 is sleeved on the outside of the extrusion rod 77. One end of the second compression spring 78 is fixedly connected to the extrusion block 76, and the other end of the second compression spring 78 is fixedly connected to the inner wall of the extrusion groove. The second compression spring 78 is always in a compressed state, so that the extrusion block 76 can provide a stable elastic force to the extrusion rod 77, so that the extrusion rod 77 can be stably engaged with the square groove. When it is necessary to rotate the extrusion wheel 74, the extrusion rod 77 can be pulled upward to disengage from the square groove and rotate 90°, so that the extrusion wheel 74 can rotate 90°, thereby realizing the extension and retraction adjustment of the positioning rod 71.

[0034] Furthermore, the outer wall of the metering tube 2 is embedded with an observation window 8, which is made of transparent material. The outer wall of the metering tube 2 is marked with a scale. The observation window 8 can be used to observe whether the internal material has been completely cleaned. The scale can be used to mix liquid materials.
