Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of circulating cooling equipment technology, and more specifically, to a circulating cooling equipment for powder coating production. Background Technology

[0002] Powder coating is a new type of solvent-free, 100% solid powder coating that can be used in a wide range of fields. During the production of powder coating, it undergoes processes such as melt extrusion, which puts it in a molten state at high temperatures. Therefore, it needs to be cooled by cooling equipment to allow the powder coating to solidify and take shape quickly, thus transforming the flowing liquid into a solid powder.

[0003] When cooling liquid coatings, traditional cooling equipment involves installing cooling pipes inside a cooling tank, then feeding the liquid coating into the cooling tank. A circulating pump then feeds the cooling medium from the cooling tank into the cooling pipes, allowing the liquid coating to contact the surface of the cooling pipes and cool it. After cooling, the medium can be circulated back into the cooling tank through a heat exchanger for reuse.

[0004] However, when liquid coating is introduced into the cooling tank, traditional cooling equipment cannot easily place the coating in multiple batches. Therefore, if a large amount of liquid coating is introduced, the liquid on the outside will come into contact with the cooling pipes, while the liquid powder accumulated in the middle will not have good contact with the pipes, thus requiring a longer cooling time. Utility Model Content

[0005] To overcome the above-mentioned defects, embodiments of this disclosure provide a circulating cooling device for powder coating production, which solves the technical problem in the prior art that the coating is prone to uneven contact with the cooling pipes after the liquid coating is put into the cooling device.

[0006] According to one aspect, at least one embodiment of this disclosure provides a circulating cooling device for powder coating production, including a cooling mechanism, a cooling box, and a cooling pipe. The cooling mechanism is disposed on the cooling box, and the cooling pipe is installed through the cooling box. The cooling pipe is horizontally placed and configured in an S-shape. The top and side of the cooling box are provided with through slots. The device also includes an insulation box, a material hopper, a baffle assembly, and a material distribution assembly. The insulation box is fixedly installed at the through slot at the top of the cooling box, and a sliding groove is provided on the inner side wall of the insulation box. The material hopper is slidably installed in the sliding groove on the inner side wall of the insulation box via a sliding rod. The baffle assembly is disposed in the cooling box to block the coating entering the cooling box from the cooling pipe. The material distribution assembly is disposed on the side of the cooling box to drive the material hopper to move within the insulation box.

[0007] Furthermore, the baffle assembly includes an electric cylinder and a baffle plate. There are two electric cylinders, both of which are installed at the bottom of the cooling box. The baffle plate is located inside the cooling box, and the bottom end of the baffle plate is fixedly connected to the output end of the electric cylinder.

[0008] Furthermore, the bulk material assembly includes a support cover, a reciprocating screw, a screw nut, a connecting rod, and a motor. The support cover is fixedly installed on the side of the insulation box, the reciprocating screw is rotatably installed inside the support cover, the screw nut is installed on the reciprocating screw, one end of the connecting rod is fixedly installed on the side of the screw nut, the other end of the connecting rod is fixedly installed on the side of the bulk material hopper, and the connecting rod is slidably installed through the side of the insulation box. The motor is installed on the side of the support cover, and the output end of the motor is coaxially connected to the reciprocating screw.

[0009] Furthermore, it also includes a cover assembly, which includes a mounting bracket and a cover plate. Four mounting brackets are provided, and all four mounting brackets are bolted to the side of the insulation box. The cover plate is fixedly mounted on the four mounting brackets.

[0010] Furthermore, the inner wall of the support cover is provided with a sliding groove, and the lead screw nut is slidably installed in the sliding groove of the support cover via a slider.

[0011] Furthermore, two solenoid valves are connected and installed at the bottom of the bulk hopper.

[0012] Furthermore, a door is hinged to the through groove on the side of the cooling box.

[0013] Furthermore, the length of the cover plate is the same as the length of the insulated box, and the width of the cover plate is the same as the width of the insulated box.

[0014] Furthermore, two threaded holes are provided on both sides of the insulation box. When the threaded holes of the four mounting brackets correspond to the four threaded holes of the insulation box, the bottom end of the cover plate fits into the top end of the insulation box.

[0015] Furthermore, the baffle plate is made of a high-temperature resistant material.

[0016] The beneficial effects of the embodiments disclosed herein are as follows:

[0017] 1. In this disclosure, the horizontally placed S-shaped cooling pipe allows the liquid coating to contact the cooling pipe over a large area after it is placed into the cooling tank, thus improving the cooling effect. Furthermore, when the coating is poured in, the baffle assembly can block it near the cooling pipe, preventing it from falling to the bottom of the cooling tank, thereby allowing the coating to contact the cooling pipe for a longer period of time and achieve sufficient cooling.

[0018] 2. In this disclosure, during material feeding, the material hopper can be moved evenly within the insulation box by the material dispensing component, thereby ensuring that the coating is evenly distributed on the cooling pipes without accumulation, thus improving cooling efficiency.

[0019] In summary, through the cooperation of the insulation box, the bulk hopper, the baffle assembly, and the bulk assembly, this equipment enables the liquid coating to come into uniform contact with the cooling pipes, resulting in a better cooling effect. Attached Figure Description

[0028] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present disclosure and are not intended to limit the scope of the disclosure.

[0034] Example 1, as Figures 1-6 As shown, a circulating cooling device for powder coating production according to an embodiment of this disclosure is illustrated, including a cooling mechanism, a cooling tank 1, and a cooling pipe 2. The cooling mechanism is disposed on the cooling tank 1, and the cooling pipe 2 is installed through the cooling tank 1. The cooling pipe 2 is horizontally placed and configured in an S-shape. Through slots are provided on the top and sides of the cooling tank 1, such as... Figure 4 As shown, the cooling mechanism includes a water storage tank 16, a circulating pump 17, and a connecting pipe 18. The water storage tank 16 is fixedly installed on the side of the cooling tank 1. The circulating pump 17 is connected to the water storage tank 16 through the connecting pipe 18. One end of the cooling pipe 2 is connected to the outlet of the circulating pump 17, and the other end of the cooling pipe 2 is connected to the water storage tank 16 through a heat exchanger. During cooling, the circulating pump 17 draws water from the water storage tank 16 into the cooling pipe 2 through the connecting pipe 18. The liquid coating is cooled by flowing in the cooling pipe 2, and then the water is cooled back into the water storage tank 16 through the heat exchanger, thus being recycled.

[0035] It also includes an insulation box 3, a bulk material hopper 4, a baffle assembly, and a bulk material assembly. The insulation box 3 is fixedly installed at the top of the cooling box 1 in the through groove, and the inner side wall of the insulation box 3 is provided with a sliding groove. The bulk material hopper 4 is slidably installed in the sliding groove on the inner side wall of the insulation box 3 via a sliding rod. The baffle assembly is set inside the cooling box 1 to block the paint entering the cooling box 1 at the cooling pipe 2. The bulk material assembly is set on the side of the cooling box 1 to drive the bulk material hopper 4 to move inside the insulation box 3.

[0036] When cooling liquid coatings, the coating is first placed into the dispensing hopper 4, and the dispensing assembly evenly disperses the liquid coating near the cooling pipe 2. Figure 2 and Figure 6As shown, the bulk material assembly includes a support cover 7, a reciprocating screw 8, a screw nut 9, a connecting rod 10, and a motor 11. The support cover 7 is fixedly installed on the side of the insulation box 3. The reciprocating screw 8 is rotatably installed inside the support cover 7. The screw nut 9 is installed on the reciprocating screw 8. One end of the connecting rod 10 is fixedly installed on the side of the screw nut 9, and the other end of the connecting rod 10 is fixedly installed on the side of the bulk material hopper 4. The connecting rod 10 is slidably installed through the side of the insulation box 3. The motor 11 is installed on the side of the support cover 7, and the output end of the motor 11 is coaxially connected to the reciprocating screw 8. Specifically... When the motor 11 is started, the output end of the motor 11 drives the reciprocating screw 8 to rotate inside the support cover 7. It should be noted that the reciprocating screw 8 and the screw nut 9 are driven by a rolling thread, and the inner side wall of the support cover 7 is provided with a sliding groove. The screw nut 9 is slidably installed in the sliding groove of the support cover 7 through a slider. The screw nut 9 drives the connecting rod 10 to move, and the connecting rod 10 drives the bulk hopper 4 to move inside the insulation box 3. Since two solenoid valves 14 are connected and installed at the bottom of the bulk hopper 4, the solenoid valves 14 are opened, and the liquid coating is scattered to the cooling pipe 2 for cooling.

[0037] During material feeding, the coating can be blocked at the top and bottom of the cooling pipe 2 by the material baffle assembly, such as... Figure 3 As shown, the baffle assembly includes an electric cylinder 5 and a baffle plate 6. There are two electric cylinders 5, both of which are installed at the bottom of the cooling box 1. The baffle plate 6 is located inside the cooling box 1, and the bottom of the baffle plate 6 is fixedly connected to the output end of the electric cylinder 5. Specifically, when the electric cylinder 5 is started, the output end of the electric cylinder 5 moves the baffle plate 6 upward to below the cooling pipe 2, and the paint falls onto the baffle plate 6. The paint on the baffle plate 6 covers the cooling pipe 2. During feeding, a portion can be fed, and feeding is stopped when the paint has slightly exceeded the top of the cooling pipe 2. The baffle plate 6 is made of a high-temperature resistant material, so most of the paint can contact the cooling pipe 2, resulting in a better cooling effect. After cooling, the liquid paint is cooled and fixed. A box door 15 is hinged to the through groove on the side of the cooling box 1. The fixed paint can be taken out by opening the box door 15.

[0038] Working principle: During cooling, the electric cylinder 5 first moves the baffle plate 6 upwards to below the cooling pipe 2 without contacting it. Then, the liquid coating is placed into the bulk hopper 4. It should be noted that the bulk hopper 4 and the solenoid valve 14 are also made of high-temperature resistant material. When the solenoid valve 14 is opened, the motor 11 is started. The output of the motor 11 drives the reciprocating screw 8 to rotate inside the support cover 7. The screw nut 9 drives the connecting rod 10 to move. The connecting rod 10 drives the bulk hopper 4 to move inside the insulation box 3. The liquid coating in the bulk hopper 4 falls onto the baffle plate 6 through the solenoid valve 14. Then, the feeding stops when the material has submerged the cooling pipe 2. The circulating pump 17 draws water from the water storage tank 16 into the cooling pipe 2 through the connecting pipe 18. The liquid coating is cooled by flowing through the cooling pipe 2. It should be noted that the cooling box 1 has a temperature sensor inside. When the temperature reaches a certain level, the cooling box stops, and the box door 15 is opened to remove the solid powder. It should also be noted that sealing rings are installed at all sliding parts inside the device to ensure the device's airtightness.

[0039] In Example 2, because a seal must be maintained during cooling, the top of the insulation box 3 is open; therefore, it is sealed using a capping assembly, such as... Figure 5 As shown, the sealing assembly includes mounting brackets 12 and sealing plates 13. There are four mounting brackets 12, and all four mounting brackets 12 are installed on the side of the insulation box 3 by bolt threads. The sealing plates 13 are fixedly installed on the four mounting brackets 12. Since there are two threaded holes on both sides of the insulation box 3, when the threaded holes of the four mounting brackets 12 correspond to the four threaded holes of the insulation box 3 respectively, the bottom end of the sealing plate 13 fits against the top end of the insulation box 3. The length of the sealing plate 13 is consistent with the length of the insulation box 3, and the width of the sealing plate 13 is consistent with the width of the insulation box 3. Therefore, during cooling, the sealing plate 13 can be placed on the top end of the insulation box 3, and then the bolt threads are installed in the threaded holes of the mounting brackets 12 and the insulation box 3 to fix it.

[0040] Working principle: Place the cover plate 13 on the top of the heat preservation box 3, and then fix it by threading the bolts into the threaded holes of the mounting bracket 12 and the heat preservation box 3. When the cooling is complete or the material in the bulk hopper 4 is insufficient, unscrew the bolts and pick up the cover plate 13.

[0041] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure 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 solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
