Description

Technical Field

[0001] This application relates to the field of acrylamide technology, and in particular to a reaction vessel for acrylamide processing. Background Technology

[0002] Acrylamide is a small organic molecule monomer with a double bond structure. Acrylamide needs to be polymerized in a reactor to produce polyacrylamide. Polyacrylamide is widely used as a highly efficient water treatment flocculant in municipal sewage purification, oil extraction thickening and other fields.

[0003] However, after processing, residues remain on the inner wall of the reactor. Cleaning these residues is tedious and difficult, and over time, the residues accumulate, not only reducing the internal space of the reactor but also seriously affecting the quality of the product. Utility Model Content

[0004] To facilitate the cleaning of residues on the inner wall of the reactor and improve the cleanliness of the reactor interior, this application provides a reactor for acrylamide processing.

[0005] The technical solution for an acrylamide processing reactor provided in this application is as follows:

[0006] A reaction vessel for acrylamide processing includes a vessel body and a vessel lid. The vessel lid is fixed to the top of the vessel body. Several support blocks are fixedly arranged at circumferential intervals on the bottom of the vessel lid, and a rotating ring is shared by all the support blocks. A fixing block is fixedly arranged on the side wall of each support block, and a thrust spring is fixedly arranged at the bottom of each fixing block. A cleaning ring is fixedly arranged at the bottom of all the thrust springs. The outer wall of the cleaning ring is in contact with the inner wall of the vessel body, and the thrust spring drives the cleaning ring away from the fixing block. A tension rope is wound around the side wall of the rotating ring, and the end of the tension rope away from the rotating ring is fixedly connected to the cleaning ring. A driving assembly is also provided on the vessel lid, which is used to drive the rotating ring to rotate.

[0007] By adopting the above technical solution, when it is necessary to clean the inner wall of the reactor, the drive assembly is activated, which drives the rotating ring to rotate reciprocally. When the rotating ring rotates in one direction, it winds up the tension rope, which pulls the cleaning ring upwards; when the rotating ring rotates in the other direction, it loosens the tension rope, and the thrust spring pushes the cleaning ring downwards. Because the outer wall of the cleaning ring is in contact with the inner wall of the reactor, residues on the inner wall of the reactor can be removed during the up-and-down movement of the cleaning ring. This facilitates the cleaning of residues on the inner wall of the reactor and improves the cleanliness of the reactor interior. When the reactor is undergoing reaction processing, the rotating ring winds up the tension rope, positioning the cleaning ring at the upper part of the reactor interior.

[0008] Preferably, a multi-stage telescopic rod is provided between the fixing block and the cleaning ring. The multi-stage telescopic rod is composed of several telescopic segments nested in sequence, and adjacent telescopic segments slide and cooperate in the vertical direction. The uppermost telescopic segment is fixedly connected to the fixing block, and the lowermost telescopic segment is fixedly connected to the cleaning ring.

[0009] By adopting the above technical solution, the multi-stage telescopic rod can extend and retract accordingly during the up-and-down movement of the cleaning ring, providing stable guidance and support for the movement of the cleaning ring. Since the multi-stage telescopic rod is composed of several telescopic segments nested sequentially, and adjacent telescopic segments slide and cooperate in the vertical direction, the distance from the cleaning ring to the vessel lid is minimized when the multi-stage telescopic rod is fully retracted.

[0010] Preferably, there are several tension ropes, each corresponding to a multi-stage telescopic rod. The side wall of the uppermost telescopic segment has a thread hole for the corresponding tension rope to pass through. The tension rope is fixedly connected to the cleaning ring inside the multi-stage telescopic rod.

[0011] By adopting the above technical solution, several tension ropes are set up, each corresponding to a multi-stage telescopic rod. The tension ropes pass through a wire hole located on the side wall of the uppermost telescopic section and are fixedly connected to the cleaning ring within the multi-stage telescopic rod, allowing the tension ropes to operate under the protection of the multi-stage telescopic rod. On one hand, the multi-stage telescopic rod prevents the tension ropes from tangling with other components inside the vessel during the movement of the cleaning ring, ensuring smooth extension and retraction of the tension ropes and making the up-and-down movement of the cleaning ring more stable and reliable. On the other hand, the combined action of multiple tension ropes, applying tension to different parts of the cleaning ring simultaneously, improves the balance of the cleaning ring during its up-and-down movement.

[0012] Preferably, a guide tube is fixedly installed on the wire hole. One end of the guide tube is located inside the multi-stage telescopic rod, and the other end of the guide tube is located outside the multi-stage telescopic rod and directly opposite the rotating ring. The tension rope passes through the guide tube, and the edges of both ends of the inner wall of the guide tube are rounded.

[0013] By adopting the above technical solution, the guide tube further optimizes the running path of the tension rope. Since one end of the guide tube is located inside the multi-stage telescopic rod, and the other end is located outside the multi-stage telescopic rod and directly opposite the rotating ring, it can guide the tension rope smoothly from the rotating ring to the inside of the multi-stage telescopic rod and connect with the cleaning ring, making the direction of the tension rope more standardized and orderly. During the winding and unwinding process of the tension rope, friction inevitably occurs between it and the edges of both ends of the inner wall of the guide tube. The rounded corners can greatly reduce the friction between the tension rope and the guide tube, reduce the wear of the tension rope, and extend its service life.

[0014] Preferably, the drive assembly includes a first motor, a gear, and an internal gear ring. The first motor is fixed on the vessel lid, and the drive shaft of the first motor passes through the vessel lid and is fixedly connected to the gear. The internal gear ring is integrally formed on the inner wall of the rotating ring, and the gear meshes with the internal gear ring.

[0015] By adopting the above technical solution, when it is necessary to drive the rotating ring to rotate, the first motor is started. The drive shaft of the first motor drives the gear to rotate. Since the gear meshes with the internal gear ring, the rotation of the gear is transmitted to the internal gear ring, thereby causing the rotating ring, which is integrally formed with the internal gear ring, to rotate.

[0016] Preferably, a protective cover is fixed to the bottom of all the support blocks, and the rotating ring, gear, and internal gear ring are all located inside the protective cover.

[0017] By adopting the above technical solution, the protective cover can prevent the material in the reactor from splashing onto the rotating ring, gear and internal gear ring. During the acrylamide processing, there may be material splashing in the reactor. If this material adheres to the rotating ring, gear and internal gear ring, it may affect the normal operation of the gear and internal gear and increase the transmission resistance.

[0018] Preferably, the rotating ring has a plurality of rope-winding grooves on its peripheral wall, each of which corresponds to a tension rope, and the tension rope is wound around the rotating ring along the corresponding rope-winding groove.

[0019] By adopting the above technical solution, the opening of the rope groove provides a dedicated space for the winding of the tension rope. Since the rope groove corresponds one-to-one with the tension rope, the tension rope is wound on the rotating ring along the corresponding rope groove, which can minimize the entanglement and interference between the tension ropes and ensure that the winding and unwinding process of each tension rope can be carried out independently and smoothly when the rotating ring rotates.

[0020] Preferably, a rotating shaft is rotatably mounted in the center of the vessel lid, and stirring blades are fixedly mounted on the side wall of the rotating shaft. A second motor is fixedly mounted on the top of the vessel lid, and the drive shaft of the second motor passes through the vessel lid and is coaxially fixed with the rotating shaft.

[0021] By adopting the above technical solution, when the second motor is started, the drive shaft of the second motor will drive the rotating shaft to rotate, which will cause the stirring blades to swing. In the acrylamide processing reaction, as the rotating shaft rotates, the stirring blades stir the materials in the reaction vessel, so that the materials in the reaction vessel are fully mixed, the reaction speed is accelerated, and the uniformity and completeness of the reaction are improved.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. By setting up a drive assembly, a rotating ring, a tension rope, a thrust spring, and a cleaning ring, when it is necessary to clean the inner wall of the reactor, the drive assembly is activated to drive the rotating ring to rotate back and forth, causing the tension rope to continuously tighten and loosen. This allows the cleaning ring to move up and down under the combined action of the thrust spring and the tension rope, removing the residue on the inner wall of the reactor. This facilitates the cleaning of residue on the inner wall of the reactor and improves the cleanliness of the reactor interior.

[0024] 2. By setting up multi-stage telescopic rods, guide tubes, rope winding grooves, and protective covers, the multi-stage telescopic rods provide stable guidance and support for the movement of the cleaning ring, the guide tubes optimize the running path of the tension ropes and reduce friction, the rope winding grooves prevent the tension ropes from tangling together, and the protective covers prevent materials from splashing onto the transmission components, thus ensuring the stability and reliability of the cleaning device and extending the service life of the components.

[0025] 3. By setting up a rotating shaft, stirring blades, and a second motor, starting the second motor can drive the rotating shaft and stirring blades to rotate, stirring the materials in the reactor, so that the materials are fully mixed, accelerating the reaction speed, and improving the uniformity and completeness of the reaction.

[0031] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0032] This application discloses a reaction vessel for acrylamide processing. (Refer to...) Figure 1 and Figure 2 The reactor comprises a support frame, a vessel body 1, and a vessel lid 2. The vessel body 1 is fixed to the support frame, and the vessel lid 2 is fixed to the top of the vessel body 1. The side wall of the vessel body 1 has a feed port for injecting raw materials into the vessel body 1, and the bottom of the vessel body 1 has a discharge port for discharging the reactants inside the vessel body 1. A rotating shaft 22 is rotatably mounted in the center of the vessel lid 2, and stirring blades 221 are fixedly mounted on the side wall of the rotating shaft 22. A second motor 21 is fixedly mounted on the top of the vessel lid 2, and the drive shaft of the second motor 21 passes through the vessel lid 2 and is coaxially fixed to the rotating shaft 22. During the reaction process, the discharge port is first closed, and the required raw materials are injected into the vessel body 1 through the feed port. Then, the second motor 21 is started, driving the rotating shaft 22 to rotate, causing the stirring blades 221 to rotate at high speed, thereby fully stirring the raw materials inside the vessel body 1, ensuring uniform mixing, and accelerating the reaction. After the reaction process is completed, the discharge port is opened, and the reactants are discharged from the vessel body 1.

[0033] Reference Figure 2 and Figure 3 The bottom of the vessel lid 2 is evenly spaced and fixedly provided with several support blocks 3 in the circumferential direction. In this embodiment, there are three support blocks 3. A mating groove is opened on the side of the support block 3 facing the rotating shaft 22, and a rotating ring 31 rotates together in the mating groove of all support blocks 3. A fixing block 32 is fixedly provided on the side wall of the support block 3, and a cleaning ring 34 is provided below the fixing block 32. The outer wall of the cleaning ring 34 is in contact with the inner wall of the vessel body 1. The rotating shaft 22 passes through the center of the rotating ring 31 and the cleaning ring 34. A multi-stage telescopic rod 5 is also provided between each fixing block 32 and the cleaning ring 34. The multi-stage telescopic rod 5 is composed of several telescopic segments 51 nested in sequence, and adjacent telescopic segments 51 slide and engage in the vertical direction. It is worth noting that there is a limit between adjacent telescopic segments 51, so that adjacent telescopic segments 51 cannot be completely separated. The uppermost telescopic segment 51 is fixedly connected to the fixing block 32, and all the lowermost telescopic segments 51 are fixedly connected to the cleaning ring 34.

[0034] Reference Figures 2 to 4The multi-stage telescopic rod 5 is equipped with a thrust spring 33. The top end of the thrust spring 33 is fixedly connected to the fixing block 32, and the bottom end of all the thrust springs 33 is fixedly connected to the cleaning ring 34. The thrust springs 33 drive the cleaning ring 34 away from the fixing block 32. Several tension ropes 311 are fixed and wound on the side wall of the rotating ring 31. In this embodiment, there are three tension ropes 311. Specifically, several rope grooves 312 are opened on the peripheral wall of the rotating ring 31. There are three rope grooves 312, and all the rope grooves 312 are distributed at intervals in the vertical direction. The rope grooves 312 correspond one-to-one with the tension ropes 311, and the tension ropes 311 are wound around the rotating ring 31 along the corresponding rope grooves 312. Each tension rope 311 corresponds to a multi-stage telescopic rod 5. A cable guide hole 52 is provided on the side wall of the uppermost telescopic segment 51 for the corresponding tension rope 311 to pass through. The end of the tension rope 311 away from the rotating ring 31 is inside the multi-stage telescopic rod 5 and fixedly connected to the cleaning ring 34. Specifically, a guide tube 53 is fixedly installed on the cable guide hole 52. One end of the guide tube 53 is inside the multi-stage telescopic rod 5, and the other end is outside the multi-stage telescopic rod 5, directly facing the rotating ring 31. The tension rope 311 passes through the guide tube 53, and rounded corners 531 are provided at both ends of the inner wall of the guide tube 53.

[0035] Reference Figure 2 and Figure 3 The vessel lid 2 is also equipped with a drive assembly 4, which drives the rotating ring 31 to rotate. Specifically, the drive assembly 4 includes a first motor 41, a gear 42, and an internal gear ring 43. The first motor 41 is fixed to the vessel lid 2, and its drive shaft passes through the vessel lid 2 and is fixedly connected to the gear 42. The internal gear ring 43 is integrally formed on the inner wall of the rotating ring 31, and the gear 42 and the internal gear ring 43 mesh with each other. A protective cover 11 is fixed to the bottom of all the support blocks 3, and the rotating ring 31, gear 42, and internal gear ring 43 are all located inside the protective cover 11.

[0036] The implementation principle of the acrylamide processing reactor in this application embodiment is as follows: When it is necessary to clean the residue on the inner wall of the reactor body 1, the first motor 41 is started. The first motor 41 drives the gear 42 to rotate reciprocally. The gear 42 meshes with the internal gear ring 43, thereby driving the internal gear ring 43 and the rotating ring 31 to rotate. During the rotation of the rotating ring 31, the tension rope 311 will be wound up or unwound according to its rotation direction. When the rotating ring 31 rotates in one direction, the tension rope 311 is wound up, and the tension rope 311 pulls the cleaning ring 34 upward against the elastic force of the thrust spring 33. When the rotating ring 31 rotates in another direction, the tension rope 311 is unwound, and the thrust spring 33 pushes the cleaning ring 34 downward. During the up and down movement of the cleaning ring 34, since the outer wall of the cleaning ring 34 is always in contact with the inner wall of the reactor body 1, the cleaning ring 34 can scrape off the residual material on the inner wall of the reactor body 1, thereby cleaning the inner wall of the reactor body 1 and improving the cleanliness of the inside of the reactor body 1. During this process, the multi-stage telescopic rod 5 extends and retracts as the cleaning ring 34 moves, providing stable guidance for the cleaning ring 34.

[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
