A cooling device for heat treatment of ceramic powder coating with rapid cooling function

Abstract

This invention provides a ceramic powder coating heat treatment cooling device with rapid cooling function, belonging to the technical field of powder heat treatment cooling devices. It includes a tank, a hopper, and a discharge pipe. The top of the tank is connected to a feed pipe, and an end cap is fitted onto the top of the feed pipe. A cooling chamber is located inside the tank, and a circulation mechanism is located at the top of the tank. This invention activates a fan at regular intervals. The fan draws ceramic powder from the bottom of the hopper upwards through the feed pipe, automatically conveying the ceramic powder to the discharge pipe. A filter separates the ceramic powder from the air. The ceramic powder is retained inside the discharge pipe and enters the tank through the bottom of the discharge pipe, while the air is discharged to the outside. This allows the ceramic powder to circulate inside the tank, exchanging different types of ceramic powder into the cooling chamber, resulting in uniform cooling of the ceramic powder inside the tank.

[0017] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0018] according to Figure 1 , 2 As shown in Figure 3, this embodiment proposes a ceramic spray powder heat treatment cooling device with rapid cooling function, including a tank 1, a hopper 2, and a discharge pipe 3. The bottom of the tank 1 is fixedly connected to the hopper 2, and the bottom of the hopper 2 is connected to the discharge pipe 3. The top of the tank 1 is connected to the inlet pipe 4, and the top of the inlet pipe 4 is fitted with an end cap. The tank 1 is equipped with a cooling chamber 5 inside, and a circulation mechanism is provided at the top of the tank 1. The end cap at the top of the inlet pipe 4 is opened, and the ceramic spray powder is poured into the tank 1. Then, the end cap is put back on the top of the inlet pipe 4, and the ceramic spray powder falls into the cooling chamber 5 to exchange heat and reduce the temperature. Every once in a while, the circulation mechanism drives the ceramic spray powder to circulate inside the tank 1, and different ceramic spray powders are exchanged to enter the cooling chamber 5, so that the ceramic spray powder is uniformly cooled inside the tank 1. The cooled ceramic spray powder is transported to the outside by opening the solenoid valve on the discharge pipe 3.

[0019] The circulation mechanism includes a fan 19, a filter 20, a discharge pipe 21, and a feeding pipe 22. The fan 19 is fixedly installed on the top of the tank 1. The input end of the filter 20 is connected to the filter 20, and one end of the filter 20 is connected to the discharge pipe 21. The bottom end of the discharge pipe 21 is connected to the inside of the tank 1, and one end of the discharge pipe 21 is connected to the bottom end of the collection hopper 2 through the feeding pipe 22. The fan 19 is turned on at regular intervals. The fan 19 draws the ceramic coating powder from the bottom of the collection hopper 2 upward through the feeding pipe 22, and automatically transports the ceramic coating powder to the discharge pipe 21. The filter 20 can separate the ceramic coating powder from the air. The ceramic coating powder is trapped inside the discharge pipe 21 and enters the inside of the tank 1 along the bottom end of the discharge pipe 21, while the air is discharged to the outside. This allows the ceramic coating powder to circulate inside the tank 1, exchanging different ceramic coating powders into the cooling chamber 5, so that the ceramic coating powder is cooled evenly inside the tank 1.

[0020] The interior of the cooling chamber 5 is hollow, and multiple diversion holes 6 are provided inside the cooling chamber 5. One side of the cooling chamber 5 is connected to a water inlet pipe 7, and the other side of the cooling chamber 5 is connected to a return pipe 8. The top ends of the water inlet pipe 7 and the return pipe 8 extend through the top of the tank body 1. The water inlet pipe 7 and the return pipe 8 are respectively connected to the water outlet pipe and the water inlet pipe of the external cooling tower. The cold water in the cooling tower is transported into the interior of the cooling chamber 5 through the water outlet pipe and the water inlet pipe 7. The ceramic coating powder enters the interior of the cooling chamber 5 through the diversion holes 6. The ceramic coating powder exchanges heat with the cooling water inside the cooling chamber 5 to reduce its own temperature. The water that has absorbed heat flows back into the interior of the cooling tower through the return pipe 8. After the cooling tower reduces the temperature of the water, it continues to be transported into the interior of the cooling chamber 5 to continuously dissipate heat from the ceramic coating powder.

[0021] The top of the hopper 2 is fixedly connected to an inlet 11, and the inner side of the inlet 11 is symmetrically fixedly connected to a locking block 9. The cooling chamber 5 is symmetrically provided with locking grooves 10 on both sides. The outer wall of the locking block 9 is engaged with the inner wall of the locking groove 10. The cooling chamber 5 is placed above the hopper 2, and the locking grooves 10 on both sides of the cooling chamber 5 are vertically parallel to the locking block 9 on the inner side of the inlet 11. The cooling chamber 5 is inserted into the inner side of the inlet 11 along the outer wall of the locking block 9 to install the cooling chamber 5 inside the inlet 11. The locking block 9 and the locking groove 10 serve as positioning.

[0022] The top of the inlet 11 is provided with an annular groove 13, and the top of the cooling chamber 5 is provided with a retaining ring 12. The bottom of the retaining ring 12 is engaged with the inside of the annular groove 13. After the cooling chamber 5 is engaged into the inside of the inlet 11, the retaining ring 12 is placed on the top of the inlet 11. Then, the retaining ring 12 is pressed down and moved to engage the bottom of the retaining ring 12 into the inside of the annular groove 13. The top of the cooling chamber 5 is pressed together by the retaining ring 12, and the cooling chamber 5 is completely fixed to the top of the hopper 2.

[0023] The outer side of the tank body 1 is provided with an outer edge 18. The outer side of the collecting hopper 2 and the interior of the outer edge 18 are provided with multiple connecting holes 14, and the positions of two sets of connecting holes 14 are parallel vertically. A connecting mechanism is provided inside the connecting holes 14. The connecting mechanism includes a connecting rod 15, a bolt 16, and a fixing sleeve 17. A connecting rod 15 is inserted into one set of vertically parallel connecting holes 14. The top end of the connecting rod 15 is fixedly connected to a bolt 16, and the top end of the bolt 16 is threadedly connected to a fixing sleeve 17. After the cooling chamber 5 is fixed above the collecting hopper 2, the top of the collecting hopper 2 is fitted against it. At the bottom of tank 1, insert multiple connecting rods 15 into the connecting holes 14, and then tighten the fixing sleeve 17 to the top of the bolt 16. The fixing sleeve 17 and the connecting rods 15 clamp the outer edge 18 and the outer side of the hopper 2 respectively, so as to fix the hopper 2 to the bottom of tank 1. When disassembling, simply unscrew the fixing sleeve 17 at the top of the bolt 16, pull the connecting rod 15 out from the connecting hole 14, and the hopper 2 will be separated from the bottom of tank 1. Then, pull out the return pipe 8 and the water inlet pipe 7 from the top of tank 1 to clean the cooling chamber 5 at the top of the hopper 2.

[0024] The ceramic powder coating heat treatment cooling device turns on the fan 19 at regular intervals. The fan 19 draws the ceramic powder coating from the bottom of the collection hopper 2 upward through the feeding pipe 22, and automatically transports the ceramic powder coating to the discharge pipe 21. The filter 20 separates the ceramic powder coating from the air. The ceramic powder coating is trapped inside the discharge pipe 21 and enters the tank 1 through the bottom of the discharge pipe 21, while the air is discharged to the outside. This allows the ceramic powder coating to circulate inside the tank 1, exchanging different ceramic powder coatings into the cooling chamber 5, so that the ceramic powder coating is cooled evenly inside the tank 1.
