Description

Technical Field

[0001] This utility model relates to the field of coating curing agent production technology, specifically to a water circulation cooling device for producing coating curing agents. Background Technology

[0002] Curing agents, also known as hardeners, curing agents, or stabilizers, are substances or mixtures that promote or control curing reactions. Resin curing is an irreversible process in which thermosetting resins undergo chemical reactions such as condensation, ring closure, addition, or catalysis. Curing is accomplished by adding curing (crosslinking) agents, which are essential additives. Whether used as adhesives, coatings, or casting materials, curing agents must be added; otherwise, the curing agent cannot cure. During the production process, curing agents need to be heated to a certain temperature in a reaction vessel and kept at that temperature for the reaction to proceed. After the reaction, the curing agent needs to be rapidly cooled to complete the preparation. Existing reaction vessels have poor stirring effects and low cooling efficiency, which affects the efficiency of curing agent preparation.

[0003] To address the aforementioned technical problems, Chinese Patent No. CN221763926U discloses a water circulation cooling device for producing coating curing agents, comprising a reaction vessel, a support leg fixedly connected to the bottom of the reaction vessel, a support plate fixedly connected to the support leg, a motor fixedly connected to the support plate, a drive turntable fixedly connected to the output end of the motor away from the support plate, a rotating shaft fixedly connected to the output end of the support plate, a fixed column rotatably connected to the rotating shaft, the fixed column fixedly connected to the drive turntable, and a sector gear fixedly connected to the rotating shaft, the sector gear meshing with a gear.

[0004] Although the existing technical solution can quickly circulate and cool the high-temperature curing agent, when the cooling fan is drawing in air, external impurities are carried by the airflow and rushed towards the dust screen. A large number of impurities will adhere to the surface of the dust screen, which can easily clog the filter holes of the dust screen and thus affect the ventilation and heat dissipation effect.

[0024] Example: Please refer to Figures 1-3 This utility model provides a technical solution:

[0025] A water circulation cooling device for producing coating curing agents includes a reactor 1. A conveying pipe is installed on one side of the reactor 1, and a valve is installed on the conveying pipe. A cooling tank body 2 is installed at the other end of the conveying pipe.

A circulating water pump is installed on the cooling pipe. A cooling fan 4 is installed at one end of the inner side of the air inlet pipe 3. A dustproof net 5 is installed at the end of the air inlet pipe 3 near the cooling fan 4. A cleaning brush mechanism is installed at the top of the cooling tank body 2, located on one side of the air inlet pipe 3. The cleaning brush mechanism includes... The device comprises a movable brush assembly, a flushing and recovery assembly, and a connecting assembly. The connecting assembly is used to assemble and disassemble the flushing and recovery assembly and the movable brush assembly. The flushing and recovery assembly is used to rinse and recover impurities adhering to the movable brush assembly. The movable brush assembly is used to clean the dustproof net 5 by brushing. During use, the flushing and recovery assembly and the movable brush assembly can be assembled and disassembled via the connecting assembly. The flushing and recovery assembly rinses and recovers impurities adhering to the movable brush assembly, while the movable brush assembly cleans the dustproof net 5 by brushing. The device has a simple structure, is easy to operate, facilitates cleaning impurities on the surface of the dustproof net 5, and ensures effective ventilation during heat dissipation and cooling, further improving its practicality.

[0026] In this embodiment, as Figure 1 , Figure 2 and Figure 3As shown, the movable brush assembly includes a first motor 6 mounted on the connecting assembly. An adjusting cylinder 7 is mounted on the top of the first motor 6. A threaded rod 8 is rotatably connected to the inner side of the adjusting cylinder 7. An adjusting plate 9 is threadedly connected to the outer side of the threaded rod 8. The adjusting plate 9 is slidably connected to the inner side of the adjusting cylinder 7. The drive end of the first motor 6 extends to the inner side of the adjusting cylinder 7 and is fixedly connected to one end of the threaded rod 8. A brush holder 10 is mounted on the other end of the adjusting plate 9. A sponge brush 13 is mounted on the bottom of the inner side of the brush holder 10. First, the processed material can enter the cooling pipe through the circulating water pump. The cooling fan 4 is started to blow air into the air inlet pipe 3 and into the cooling box body 2 to cool the processed material. When cleaning the dustproof net 5, the first motor 6 can be started to drive the threaded rod 8 to rotate, so that the adjusting plate 9 slides in the adjusting groove and drives the fixed frame 12 to brush the surface of the dustproof net 5. The first motor 6 can rotate forward or backward to realize the reciprocating brushing of the sponge brush 13 and sweep off the adhering dust and impurities.

[0027] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the connecting assembly includes a placement plate 11 installed at one end of the top of the cooling box body 2. A rubber pad 14 overlaps one side of the placement plate 11, and a fixing bracket 12 is installed on the other side of the rubber pad 14.

A locking block 15 is slidably connected inside the slot, and one end of the locking block 15 is fixedly connected to the outer wall of the placement plate 11. A movable groove is opened on one side of the slot inside the fixing bracket 12, and a movable plate 16 is slidably connected inside the movable groove. The inner side of the movable groove communicates with the inner side of the slot. First springs 17 are installed at both ends of one side of the 16 and between the inner wall of the movable groove. Then, when assembling the flushing and recycling assembly and the movable brush assembly, the fixing frame 12 can be attached to the placement plate 11, while squeezing the rubber pad 14. At this time, the locking block 15 enters the inner side of the slot and contacts the movable plate 16. The inclined surfaces 20 of the two abut against each other, forcing the movable plate 16 to squeeze the two sets of first springs 17 to retract. After the locking block 15 is fully pushed into the inner side of the slot, the first spring 17 can drive the movable plate 16 to pop out and abut against the protruding end of the locking block 15, locking the position of the flushing and recycling assembly and the movable brush assembly.

[0028] In this embodiment, as Figure 1 , Figure 2 and Figure 3As shown, one end of the top of the fixed frame 12 has a groove extending into the inner side of the movable slot. A pull rod 18 is installed on one side of the movable plate 16 between the two sets of first springs 17. The pull rod 18 has an L-shaped side cross-section and is slidably connected to the groove. A pull ring 19 is rotatably connected to one end of the pull rod 18 extending to the outer side of the fixed frame 12. The opposite ends of the movable plate 16 and the locking block 15 both have mutually fitting inclined surfaces 20. The other end of the outer wall of the fixed frame 12 is fixedly connected to one side of the first motor 6. Furthermore, when the impact... When the sponge brush 13 or other components on the brush recycling assembly and the movable brush assembly need to be inspected and maintained after a period of use, the pull ring 19 can be fastened to drive the pull rod 18 to slide inside the pull groove, allowing the movable plate 16 to retract actively inside the movable groove. After the movable plate 16 is completely away from the protruding end of the locking block 15, the rubber pad 14 is no longer squeezed and rebounds, causing the locking block 15 to move back a distance, so that the movable plate 16 can no longer press the locking block 15 tightly. At this time, the brush recycling assembly and the movable brush assembly can be inspected and maintained.

[0029] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the flushing and recycling assembly includes a water storage tank 21 installed at the top of the regulating cylinder 7. A sealing cap is installed at the top of the water storage tank 21. A flow channel is opened inside the brush holder 10. A corrugated pipe 22 extending into the flow channel is embedded in one side of the water storage tank 21. Multiple sets of electric nozzles 23 are embedded in the top of the inner side of the brush holder 10. One end of the electric nozzle 23 extends into the flow channel. A solenoid valve is installed on the corrugated pipe 22. A recycling box 24 is installed at the center of the top of the fixing frame 12. A guide channel is opened on one side of the port of the recycling box 24. Furthermore, before cleaning the sponge brush 13, the sealing cap can be opened to pre-fill the required water source through the port. Activating the solenoid valve allows the water source to flow into the flow channel along the corrugated pipe 22. Activating the electric nozzle 23 allows the water source to spray onto the sponge brush 13 through it, flushing impurities and dust into the recycling box 24 below.

[0030] The implementation principle of the water circulation cooling device for producing coating curing agent in this application embodiment is as follows: The processed material can enter the cooling pipe through the circulating water pump. The cooling fan 4 is started to blow air into the air inlet pipe 3 and into the cooling box body 2 to cool the processed material. When cleaning the dust screen 5, the first motor 6 can be started to drive the threaded rod 8 to rotate, so that the adjusting plate 9 slides in the adjusting groove, driving the fixed frame 12 to brush the surface of the dust screen 5. The first motor 6 can rotate forward or reverse to realize the reciprocating brushing of the sponge brush 13, sweeping off the adhering dust and impurities. When assembling the flushing and recycling component and the movable brushing component, the fixed frame 12 can be attached to the placement plate 11, and the rubber pad 14 is squeezed at the same time. At this time, the locking block 15 enters the inner side of the slot and contacts the movable plate 16. The inclined surfaces 20 of the two abut against each other, forcing the movable plate 16 to squeeze the two sets of first springs 17 to retract. After the locking block 15 is completely pushed into the inner side of the slot, the first springs 17 The movable plate 16 can be ejected and abutted against the protruding end of the locking block 15, locking the positions of the flushing and recycling component and the movable brush assembly. When the sponge brush 13 or other components on the flushing and recycling component and the movable brush assembly need to be inspected and maintained after a period of use, the pull ring 19 can be fastened to drive the pull rod 18 to slide inside the pull groove, allowing the movable plate 16 to retract actively inside the movable groove. After the movable plate 16 is completely away from the protruding end of the locking block 15, the rubber pad 14 is no longer squeezed and rebounds, causing the locking block 15 to move back a distance, so that the movable plate 16 can no longer press the locking block 15 tightly. At this time, the flushing and recycling component and the movable brush assembly can be inspected and maintained. Before cleaning the sponge brush 13, the sealing cover can be opened and the required water source can be poured in in advance through the port. The solenoid valve can be activated to allow the water source to flow into the inner side of the flow channel along the corrugated pipe 22. The electric nozzle 23 can be turned on to spray water onto the sponge brush 13, flushing impurities and dust into the recycling box 24 below.

[0031] The control method of this utility model is through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Since this utility model is used to protect mechanical devices, the control method and circuit connection will not be explained in detail.

[0032] 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.
