Description

Technical Field

[0001] This utility model relates to the field of mechanical engineering technology, and in particular to a stirring device for highly stable thermosetting phenolic resin. Background Technology

[0002] High-stability thermosetting phenolic resin is a three-dimensional network cross-linked polymer material made from phenol and formaldehyde through a condensation reaction. It possesses excellent high-temperature resistance, flame retardancy, and chemical corrosion resistance, and its physicochemical properties do not easily fluctuate during processing such as stirring and molding, as well as long-term use. When stirring high-stability thermosetting phenolic resin, a stirring paddle is usually used. The stirring paddle is usually fixed to the stirring shaft. If a different stirring paddle needs to be changed, the shaft must be changed simultaneously when changing the paddle. This not only significantly increases equipment purchase and maintenance costs and prolongs downtime, but also easily damages the coaxiality of the device due to frequent disassembly and assembly, reducing stirring stability. At the same time, it cannot flexibly adapt to the needs of different stirring stages of high-stability thermosetting phenolic resin. Utility Model Content

[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0023] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0024] Example 1 Reference Figures 1-5 This is the first embodiment of the present invention. This embodiment provides a high-stability thermosetting phenolic resin stirring device. The high-stability thermosetting phenolic resin stirring device includes a main body component 1 and an installation component 2. The two components work together to facilitate the installation of the stirring shaft and the impeller.

[0025] The main component 1 includes a stirring shaft 11, a stirring paddle 12 is provided at the bottom of the stirring shaft 11, and a groove 12-1 is provided on the inner wall of the stirring paddle 12.

[0026] The stirring shaft 11 is usually installed on the inner wall of the mixing tank. The main function of the stirring shaft 11 is to connect the stirring paddle 12, so that the stirring paddle 12 can stir and mix the materials, thereby realizing the stirring of the materials. This is the prior art, and this solution will not be described in detail. Moreover, those skilled in the art can clearly understand the working principle.

[0027] Mounting component 2, located at the bottom of stirring shaft 11, includes mounting component 21. Mounting component 21 includes a fixing frame 211 fixed to the bottom of stirring shaft 11. The fixing frame 211 has two locking blocks 212 on its inner wall. The inner wall of the locking blocks 212 has a pressing groove 212-1. A support shaft 213 is fixed to one end of the locking blocks 212. A support sleeve 214 is sleeved on the outside of the support shaft 213. The support sleeve 214 is fixed to the inner wall of the fixing frame 211. A spring 215 is fixed to one end of the support shaft 213. One end of the spring 215 is fixed to the inner wall of the support sleeve 214.

[0028] A sealing ring is fixed at the bottom of the fixed frame 211 to prevent liquid from entering the fixed frame 211.

[0029] When it is necessary to install the agitator 12 and the agitator shaft 11, the agitator 12 is moved. The movement of the agitator 12 causes the slot 12-1 to move. The movement of the agitator 12 presses against the two locking blocks 212. The movement of the two locking blocks 212 presses against the support shaft 213, causing it to move. The movement of the support shaft 213 presses against the spring 215. The support sleeve 214 is a component used to support the support shaft 213. By engaging the slot 12-1 with the locking blocks 212, the initial installation of the agitator 12 and the agitator shaft 11 is completed.

[0030] Example 2 Reference Figures 1-5 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0031] Specifically, the mounting component 2 also includes a connector 22, which includes a compression rod 221 disposed on the top of the compression groove 212-1.

[0032] After installation, the stirring shaft 11 is started and begins to rotate. As the stirring shaft 11 rotates, the extrusion rod 221 moves accordingly and exerts an extrusion force on the extrusion groove 212-1; under this extrusion, the locking block 212 is displaced, and its top simultaneously extrudes the locking groove 12-1. Under the action of this extrusion force, the locking groove 12-1 drives the stirring paddle 12 to move upward, ultimately making the connection between the stirring paddle 12 and the stirring shaft 11 more stable.

[0033] Specifically, a sliding strip 222 is fixed to one end of the extrusion rod 221, and a support rod 223 is sleeved on the outside of the sliding strip 222. A groove 223-1 is opened on the inner wall of the support rod 223.

[0034] The sliding bar 222 slides on the inner wall of the groove 223-1.

[0035] The stirring shaft 11 is started and begins to rotate. As the stirring shaft 11 rotates, one end of the support rod 223 moves. The movement of the support rod 223 causes the slide groove 223-1 to squeeze the sliding bar 222, causing it to move. The movement of the sliding bar 222 then causes the pressing rod 221 to move. The movement of the pressing rod 221 further squeezes the clamping block 212, ultimately making the connection between the stirring paddle 12 and the stirring shaft 11 more secure.

[0036] Specifically, a connecting shaft 224 is inserted into the inner wall of the support rod 223, and one end of the connecting shaft 224 is fixed to the inner wall of the fixed frame 211.

[0037] The connecting shaft 224 is used to support the support rod 223 and is movably connected to the support rod 223.

[0038] Specifically, a sliding shaft 225 is inserted into the inner wall of the support rod 223.

[0039] The movement of the sliding shaft 225 will cause the support rod 223 to move.

[0040] Example 3 Reference Figure 4 and Figure 5 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0041] Specifically, a connecting frame 226 is sleeved on the outer side of the sliding shaft 225, and a support groove 226-1 is opened on the inner wall of the connecting frame 226.

[0042] The sliding shaft 225 slides on the inner wall of the support groove 226-1.

[0043] The stirring shaft 11 is started and begins to rotate. As the stirring shaft 11 rotates, the connecting frame 226 moves. The movement of the connecting frame 226 causes the support groove 226-1 to press against the sliding shaft 225, causing it to move. The movement of the sliding shaft 225 then causes the support rod 223 to move.

[0044] Specifically, the mounting component 2 also includes a clamping element 23, which further includes a movable sleeve 231 fixed to one end of the connecting bracket 226.

[0045] As the stirring shaft 11 rotates, centrifugal force is generated. This centrifugal force causes the movable sleeve 231 to move, which in turn drives the connecting frames 226 on both sides to move.

[0046] Specifically, the inner wall of the movable sleeve 231 is provided with a positioning rod 232, one end of the positioning rod 232 is fixed to the inner wall of the fixed frame 211, a fixing block 233 is fixed to the surface of the positioning rod 232, and an extension rod 234 is hinged to the inner wall of the fixing block 233.

[0047] The movable sleeve 231 is fitted on the outside of the positioning rod 232, and the fixing block 233 is used to support the extension rod 234. As the stirring shaft 11 rotates, the positioning rod 232 will also rotate synchronously, which will generate centrifugal force. The centrifugal force will cause the extension rod 234 to gradually lift up. The lifting of the extension rod 234 will squeeze the movable sleeve 231, causing the movable sleeve 231 to move.

[0048] Specifically, a centrifugal ball 235 is fixed to the bottom of the extension rod 234.

[0049] As the stirring shaft 11 rotates, the positioning rod 232 rotates synchronously; the centrifugal force generated during the rotation drives the centrifugal ball 235 to lift outward. The lifting action of the centrifugal ball 235 causes the extension rod 234 to move synchronously, and the lifting of the extension rod 234 will exert a squeezing force on the movable sleeve 231, ultimately pushing the movable sleeve 231 to move.

[0050] Specifically, a positioning shaft 236 is fixed at the top of the movable sleeve 231, and one end of the positioning shaft 236 slides on the inner wall of the fixed frame 211.

[0051] The positioning shaft 236 is used to support the movable sleeve 231. The movement of the movable sleeve 231 will cause the positioning shaft 236 to slide on the inner wall of the fixed frame 211, making the movable sleeve 231 more stable when moving.

[0052] When assembling the stirring paddle 12 with the stirring shaft 11, first push the stirring paddle 12 towards the bottom of the stirring shaft 11. During the movement of the stirring paddle 12, the groove 12-1 on its inner wall will simultaneously press the two locking blocks 212 on the inner wall of the fixing frame 211. The pressed locking blocks 212 drive the support shaft 213 at one end to move into the support sleeve 214. When the support shaft 213 moves, it will compress the spring 215 in the support sleeve 214. When the stirring paddle 12 moves to the designated position, the groove 12-1 and the locking block 212 are aligned. The spring 215 rebounds and pushes the support shaft 213 to reset, thereby driving the locking block 212 to lock into the groove 12-1, completing the initial installation of the stirring paddle 12 and the stirring shaft 11. No additional tools are required, making assembly more convenient.

[0053] After initial installation, the stirring shaft 11 starts and begins to rotate. As the stirring shaft 11 rotates, the positioning rod 232 rotates synchronously. The centrifugal force generated during rotation drives the centrifugal ball 235 to lift outward. The lifting action of the centrifugal ball 235 causes the extension rod 234 to move synchronously. The lifting of the extension rod 234 will exert a squeezing force on the movable sleeve 231, ultimately pushing the movable sleeve 231 to move. The movement of the movable sleeve 231 will drive the connecting frames 226 on both sides to move. The movement of the connecting frames 226 will cause the support groove 226-1 to squeeze the sliding shaft 225 to move. The movement of the sliding shaft 225 will drive the support rod 223 to move. The movement of the support rod 223 will cause the sliding groove 223-1 to squeeze the sliding bar 222 to move. The movement of the sliding bar 222 will drive the squeezing rod 221 to move. The movement of the squeezing rod 221 will further squeeze the locking block 212. Under this squeezing, the locking block 212 will move, and its top will simultaneously squeeze the locking groove 12-1. Under the pressure, the slot 12-1 drives the agitator 12 to move upward, ultimately making the connection between the agitator 12 and the agitator shaft 11 more stable.

[0054] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
