Description

Technical Field

[0001] This utility model relates to the technical field of resin heating equipment, specifically to a circulating heating device for chemical resin coatings. Background Technology

[0002] In the production process of chemical resin coatings, water is usually used to heat the chemical resin. The resin flows in the heat exchange pipes, and currently only the outer wall of the pipes is in contact with the water. The coating closer to the center of the pipes receives poor heating, which leads to the need to increase the heating time. The heating efficiency of the coating is poor. In addition, during the water heating process, the water is in a static state and heats the flowing coating. The water temperature is prone to local overheating or underheating, which causes the chemical resin coating to not be heated evenly. This results in differences in coating performance and affects the quality of the coating.

[0003] To address the aforementioned issues, we propose a circulating heating device for chemical resin coatings. Utility Model Content

[0004] The purpose of this invention is to provide a circulating heating device for chemical resin coatings to address the aforementioned shortcomings in the technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a circulating heating device for chemical resin coatings, comprising a circulating heating cylinder, wherein a first hollow ring and a second hollow ring are fixedly provided on the top inner wall and bottom inner wall of the circulating heating cylinder, respectively, and a cavity heating tube is provided between the first hollow ring and the second hollow ring. The bottom outer wall of the first hollow ring and the top outer wall of the second hollow ring are respectively connected to a guide pipe through an opening. The other end of the guide pipe is connected to the top and bottom of the cavity heating tube, respectively. The inner wall of the cavity heating tube is equipped with spiral distribution plates arranged in an annular pattern at equal intervals, which divide the inner cavity of the cavity heating tube into spiral heating channels with equal intervals. The connection points of the guide pipe and the cavity heating tube are respectively located between adjacent spiral distribution plates. A vertically downward motor is installed on the top outer wall of the circulating heating cylinder. The output shaft of the motor is fixedly provided with a vertically downward rotating rod through a coupling. Two sets of equally distributed blades are fixedly provided on the outer wall of the rotating rod.

[0006] Preferably, the two blades are located on the top inner wall and bottom inner wall of the cavity heating tube, respectively, and the central axis of the rotating rod is on the same straight line as the central axis of the cavity heating tube.

[0007] Preferably, a motor fixing collar is fixedly provided on the top outer wall of the circulating heating cylinder, and the motor is installed inside the motor fixing collar.

[0008] Preferably, one side of the outer wall of the first hollow ring is connected to a feed pipe through an opening, and one side of the outer wall of the second hollow ring is connected to a discharge pipe through an opening. A pipe joint is fixedly provided on one end of the outer wall of the feed pipe and the discharge pipe.

[0009] Preferably, the top inner wall of the circulating heating cylinder is equipped with equally spaced electric heating tubes, and the electric heating tubes are connected to the motor via a speed switch through a wire, and the speed switch is connected to a power supply line.

[0010] Preferably, a water inlet pipe is installed on the outer wall of the top side of the circulating heating cylinder through an opening, and a sealing cap is screwed onto the outer wall of the top of the water inlet pipe.

[0011] Preferably, a temperature sensor is installed on one side of the outer wall of the circulating heating cylinder, and the detection end of the temperature sensor is located inside the circulating heating cylinder.

[0012] Preferably, the outer wall of the cavity heating tube is fixed with annular heat-conducting plates that are evenly distributed.

[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows: The cavity heating tube is equipped with a spiral distribution plate that divides the inner cavity into equally spaced spiral heating channels, allowing the coating to flow along a spiral path, increasing the flow distance of the coating. Furthermore, both the inside and outside of the cavity heating tube are in contact with heated water, and the inner and outer walls of the cavity heating tube are heated simultaneously, reducing the difficulty of heat transfer to the coating and improving the heating efficiency of the coating.

[0014] The water inside the circulating heating cylinder is heated by an electric heating tube, and the water is circulated within the cylinder by blades at the top and bottom of the hollow heating tube. This promotes the even distribution of heat within the circulating heating cylinder, avoiding localized overheating or underheating. This ensures that the chemical resin coating is heated evenly throughout the entire heating process, effectively preventing differences in coating performance caused by uneven heating and improving the production quality of the coating.

The output shaft of the motor 9 is fixed to a vertically downward rotating rod 10 via a coupling.

Two sets of equally spaced blades 11 are fixed on the outer wall of the rotating rod 10, with the two blades 11 located on the top inner wall and bottom inner wall of the cavity heating tube 4, respectively. A motor fixing collar 8 is fixed on the top outer wall of the circulating heating cylinder 1, and the motor 9 is installed inside the motor fixing collar 8. Example 3

[0022] Based on Embodiment 1, a feed pipe 12 is connected to one side of the outer wall of the first hollow ring 2 through an opening, and a discharge pipe 13 is connected to one side of the outer wall of the second hollow ring 3 through an opening. A pipe joint 14 is fixedly installed on the outer wall of one end of the feed pipe 12 and the discharge pipe 13. Electric heating tubes 15 are installed at equal intervals on the top inner wall of the circulating heating cylinder 1. The electric heating tubes 15 and the motor 9 are connected to a gear switch through a wire. The gear switch is connected to a power cord. A water filling pipe 16 is installed on one side of the outer wall of the top of the circulating heating cylinder 1 through an opening.

[0023] Working principle of this utility model: Refer to the instruction manual appendix Figure 1-6In use, this invention first adds an appropriate amount of water to the circulating heating cylinder 1 through the water inlet pipe 16 and seals it with the sealing cap 17. The electric heating tube 15 is then started to heat the water, and the motor 9 is started. The motor 9 drives the rotating rod 10 to rotate, which in turn causes the blade 11 to rotate on the inner wall of the hollow heating tube 4. The rotating blade 11 pushes the water to flow within the circulating heating cylinder 1. During the flow, the water absorbs the heat emitted by the electric heating tube 15, and the heat is simultaneously conducted to the hollow heating tube 4 through the annular heat-conducting plate 7. At this time, the chemical resin coating is introduced into the first hollow ring 2 through the pipe joint 14 on the feed pipe 12, and then enters the spiral heating channel inside the hollow heating tube 4 through the guide pipe 6. The coating flows within the spiral heating channel. During the process, the coating absorbs the heat transferred from the hollow heating tube 4 for heating. The heated coating enters the second hollow ring 3 through the other side guide tube 6 and is then discharged from the pipe joint 14 on the discharge pipe 13. The temperature sensor 18 can monitor the temperature inside the circulating heating cylinder 1 in real time so as to adjust the heating level of the electric heating tube 15 as needed. The heat is conducted to the hollow heating tube 4 through the annular heat-conducting plate 7 to heat the coating in the spiral heating channel. The heated coating enters the second hollow ring 3 through the other side guide tube 6 and is then discharged from the pipe joint 14 on the discharge pipe 13. The temperature sensor 18 can monitor the temperature inside the circulating heating cylinder 1 in real time. After the coating is heated, it flows back to the coating storage container through the discharge pipe 13.
