Description

Technical Field

[0001] This utility model belongs to the field of refrigeration pipe production technology, and in particular relates to a paint drying device for refrigerator refrigeration pipes. Background Technology

[0002] To improve stability and extend service life, refrigerator cooling pipes require external painting. Existing refrigerator cooling pipe painting and drying equipment generates paint mist and volatile organic compounds during the painting and drying process, which can easily affect worker safety. Some refrigerator cooling pipe painting and drying equipment has an air purification component on one side of the cabinet to purify the exhaust air, but the turbulent airflow of the air purification component can affect the drying effect of the drying component after painting.

[0003] Therefore, we propose a refrigerator refrigeration pipe coating and drying device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the prior art where the airflow of the air purification component affects the drying effect, and to propose a refrigerator refrigeration pipe coating and drying device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A refrigerator refrigeration pipe coating and drying device includes a cabinet. An inlet and an outlet are respectively provided on both sides of the cabinet for the refrigeration pipe to pass through. A coating assembly for coating the refrigeration pipe is fixedly installed inside the cabinet on one side of the inlet. A heating pipe is fixedly connected to the inner wall of the cabinet on one side of the outlet. A heating assembly for heating the heating pipe is provided on the outside of the heating pipe. A vertically extending mounting box is provided on the top of the cabinet. An upward-blowing fan assembly is provided on the top of the mounting box. A filter assembly is provided inside the mounting box.

[0007] Preferably, the heating assembly includes an electromagnetic induction coil spirally wound around the outside of the heating tube, and a power supply assembly is connected to both ends of the electromagnetic induction coil.

[0008] Preferably, the mounting box is located directly above the heating tube.

[0009] Preferably, the mounting box has a mounting groove on its side, and the filter assembly includes a filter plate that can be detachably and slidably disposed in the mounting groove.

[0010] Preferably, there are two filter plates, which are arranged vertically in the mounting box, and the filter plates are filled with fiberglass filter cotton and activated carbon from bottom to top.

[0011] Preferably, an annular brush is fixedly connected to the outer wall of the box on the side of the feed inlet.

[0012] In summary, the technical effects and advantages of this utility model are as follows: This refrigerator cooling pipe coating and drying device achieves a slight negative pressure inside the refrigerator through an upward-blowing fan assembly, and heats the heating pipe through a heating assembly, thereby drying the coated cooling pipe. The heating pipe ensures stable airflow at the outlet. Compared with existing devices, this avoids the problem of turbulent airflow from the air purification assembly affecting the drying assembly after coating, thus improving the drying effect.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Reference Figure 1-3 A refrigerator refrigeration pipe coating and drying device includes a cabinet 1. The cabinet 1 has an inlet 3 and an outlet 4 on its two sides for the refrigeration pipe 2 to pass through. A coating component 5 for coating the refrigeration pipe 2 is fixedly installed inside the cabinet 1 on one side of the inlet 3. A heating pipe 6 is fixedly connected to the inner wall of the cabinet 1 on one side of the outlet 4. A heating component for heating the heating pipe 6 is provided on the outside of the heating pipe 6. A mounting box 7 that runs vertically through the top of the cabinet 1 is provided. A fan assembly 8 for blowing air upwards is provided on the top of the mounting box 7. A filter assembly is provided inside the mounting box 7.

[0020] In this refrigerator refrigeration pipe coating and drying device, the heating element first heats the heating pipe 6 to raise its temperature. The refrigeration pipe 2 enters the cabinet 1 through the feed inlet 3, is coated by the coating element 5, and then enters the heating pipe 6. The heating pipe 6 heats and dries the coated refrigeration pipe 2 through heat radiation and heat convection. At the same time, the fan element 8 blows air outwards from the cabinet 1, creating a slight negative pressure inside the cabinet 1. Figure 3-4 Air enters the heating tube 6 steadily and slowly from the discharge port 4, accelerating the drying efficiency. Large particles of paint mist, dust, and volatile organic compounds inside the chamber 1 are filtered out by the filter assembly inside the mounting box 7, and the purified air is discharged from the top of the mounting box 7.

[0021] Reference Figure 2-4 The heating assembly includes an electromagnetic induction coil 9 spirally wound around the outside of the heating tube 6, with a power supply assembly 10 connected to both ends of the electromagnetic induction coil 9. In this heating assembly, an alternating current is applied to the electromagnetic induction coil 9 via the power supply assembly 10, generating eddy currents on the sidewall of the heating tube 6, thereby raising its temperature. The heated heating tube 6 then heats the painted cooling tube 2 through thermal radiation and convection. The power supply assembly 10 and the electromagnetic induction heating principle are existing technologies and will not be described in detail here.

[0022] The mounting box 7 is located directly above the heating tube 6, thus keeping it away from the painting assembly 5. This minimizes the impact of airflow from the fan assembly 8 inside the mounting box 7 on the painting assembly 5 and improves the painting effect.

[0023] The mounting box 7 has a mounting groove 11 on its side, and the filter assembly includes a filter plate 12 that is detachably and slidably disposed in the mounting groove 11. The mounting groove 11, in conjunction with the slidably disposed filter plate 12, facilitates subsequent replacement and maintenance of the filter plate 12, thereby improving its practicality.

[0024] Reference Figure 3 There are two filter plates 12, which are arranged vertically in the mounting box 7. The filter plates 12 are filled with glass fiber filter cotton 13 and activated carbon 14 from bottom to top. The high-temperature resistant glass fiber filter cotton 13 can intercept and filter out large particles of solid pollutants such as paint mist and dust in the box 1; the activated carbon 14 can adsorb volatile organic compounds (VOCs) in the box 1.

[0025] A ring-shaped brush 15 is fixedly connected to the outer wall of the housing 1 on one side of the feed inlet 3. The ring-shaped brush 15 is used to pre-clean the refrigeration pipe 2 before painting, which improves the painting effect. The ring-shaped brush 15 is installed on the outside of the housing 1, which makes it easy to replace and maintain, and also prevents impurities brushed off from entering the housing 1.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
