Description

Technical Field

[0001] The utility model relates to the technical field of casting coating pool heating, in particular to a coating pool heating system. Background Art

[0002] The coating temperature is very important in the casting field. Too low a coating temperature will cause serious quality defects. Most of the coating pools sold on the market do not have a heating function. In the winter in the north, the coating temperature cannot be guaranteed, which brings great risks to production.

[0003] like Figure 2 As shown, we added a heating rod to the original paint pool for heating and found that the power consumption was large, the heating was uneven, the local temperature was high, the temperature of the part where the heating rod was set reached above 70°C, and the temperature of other parts was only about 10°C. We also found that the bottom of the paint pool was dried out, which posed a threat to product quality and could not meet production requirements. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a coating pool heating system with compact structure, uniform coating temperature, no caking of coating pool, simple manufacture and low maintenance cost.

[0005] The utility model provides a technical solution to the above-mentioned problem: a paint pool heating system, comprising a paint pool and a water tank, a circulating water discharge pipe is arranged on the side wall of the paint pool, a heating rod is arranged in the lower part of the water tank, a water outlet interface is arranged near the bottom end of the side wall of the water tank, the water outlet interface is connected to the water inlet of the circulating water discharge pipe through a circulating water pump, and a return water interface is arranged near the top end of the side wall of the water tank, the return water interface is connected to the return water outlet of the circulating water discharge pipe.

[0006] Furthermore, the water tank is a closed water tank, and a water inlet is provided on the upper end surface.

[0007] Furthermore, a water outlet is provided on the side wall of the water tank near the bottom end.

[0008] Furthermore, a protective cover is provided on the outer side of the side wall of the water tank at the position where the heating rod is provided.

[0009] Furthermore, an electric control system is provided on the water tank, and the electric control system is electrically connected to the heating rod for controlling the temperature of the liquid in the water tank.

[0010] Furthermore, the circulating water discharge pipe is a serpentine pipe.

[0011] Furthermore, the paint pool and the water tank are arranged separately.

[0012] The utility model has the following beneficial effects:

[0013] 1. Compact structure, high practicality. The paint pool heating system is a split design with small size and easy installation. The original paint pool installation position remains unchanged. The heating system can be placed in any position that does not affect production and can be connected with a hose.

[0014] 2. Easy maintenance, saving time and effort. If a heating rod is damaged during the production process, the water tank is installed at a different location from the production equipment and will not affect production operations. It can be replaced by power outage without long downtime, which can reduce operational risks.

[0015] 3. Cost saving and reliable use. The coating pool heating system is made of steel parts processed and welded. Shearing machines, drilling machines and welding machines can be used to complete the processing and production of the product. Heating rod heating elements are used internally, and the annual maintenance cost is about 300 to 600 yuan, which is extremely low. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0019] In order to better understand the purpose, structure and function of the utility model, a coating pool heating system of the utility model is further described in detail below in conjunction with the accompanying drawings.

[0020] like Figure 1 As shown, a paint pool heating system includes a paint pool 11 and a water tank 4. A circulating water discharge pipe 10 is arranged on the side wall of the paint pool 11. A heating rod 8 is arranged in the lower part of the water tank 4. A water outlet interface 5 is provided on the side wall of the water tank 4 near the bottom end. The water outlet interface 5 is connected to the water inlet of the circulating water discharge pipe 10 through a circulating water pump 6. A return water interface 3 is provided on the side wall of the water tank 4 near the top end. The return water interface 3 is connected to the return water outlet 12 of the circulating water discharge pipe 10.

[0021] In this embodiment, the coating pool 11 and the water tank 4 are arranged separately. The water tank 4 is a closed water tank, and a water inlet 2 is provided on the upper end surface. A drain port 7 is provided near the bottom of the water tank side wall. A protective cover 9 is provided on the outer side of the side wall of the water tank 4 at the position where the heating rod 8 is provided. The water tank 4 is also provided with an electric control system 1, which includes a thermostat and a control system, and controls the temperature of the liquid in the water tank 4 by being electrically connected to the heating rod 8. The circulating water discharge pipe 10 is a serpentine pipe, which can cover a larger area of ​​the side wall of the water tank 4.

[0022] The paint pool heating system adopts a split design, which makes the overall structure compact and saves the installation area. A large area of ​​circulating water pipe 10 is made inside the original paint pool, and an electric heating hot water system is designed and manufactured separately. The hot water system is equipped with a thermostat, a circulating water pump 6 and a control system. The water temperature of the hot water system is set at 50°C. The circulating water pump 6 transports the hot water in the water tank 4 to the circulating water pipe 10 of the paint pool 11, and then circulates to the water tank 4 of the hot water system through the return pipe for heating and circulation, so as to achieve the purpose of heating the paint. Since the paint pool 11 is not directly heated by the heating rod 8, the paint pool 11 will not have local high temperature, which will cause the problem of paint agglomeration; and because the area of ​​the circulating water pipe 10 is large, the paint is heated evenly and can be maintained at about 30°C.

[0023] It is understood that the present invention is described by some embodiments, and those skilled in the art are aware that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. In addition, under the teachings of the present invention, these features and embodiments may be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present invention.
