Description

TECHNICAL FIELD

[0001] The utility model relates to refrigeration equipment accessory production technical field especially relates to a kind of anticorrosive coating coating drying system. BACKGROUND

[0002] In the use and maintenance process of air conditioner, the leakage problem of connecting pipe has been the key factor affecting product performance and user satisfaction. Through the statistical analysis of air conditioner after-sales leakage data, it is found that 80% of the leakage failures in connecting pipe are caused by corrosion. Further metallographic experiment shows that these leakage points are mainly the corrosion of copper pipe body from outside to inside. This corrosion usually occurs after after-sales installation, and the connecting pipe is in long-term contact with the heat preservation pipe in the humid environment, thereby producing chemical reaction and causing the corrosion of connecting pipe. The corrosion problem of connecting pipe not only affects the service life of air conditioner, but also increases the cost of after-sales maintenance and reduces customer satisfaction. In order to effectively solve this problem, anticorrosive coating needs to be coated on the surface of connecting pipe to reduce the leakage failure caused by corrosion.

[0003] However, simply coating anticorrosive coating is not enough to completely solve the problem. The coated anticorrosive coating needs to be quickly dried and solidified to ensure that it can be closely attached to the surface of connecting pipe and form an effective anticorrosion layer. If the anticorrosive coating cannot be dried and solidified in time after coating, the un-solidified anticorrosive coating is easy to be damaged in subsequent processing procedures, thereby affecting the anticorrosion effect.

[0004] The existing coating process of anticorrosive coating of connecting pipe is mostly carried out manually. This way is low in efficiency, uneven in coating, and long in solidification time, which limits the application of anticorrosion coating technology on connecting pipe of air conditioner.

[0005] Therefore, it is necessary to improve the existing coating method of anticorrosion coating to overcome the defects of the prior art. UTILITY MODEL CONTENT

In addition, the drying channel with variable width also considers the energy saving and consumption reduction requirement.

[0060] The box cover 12 is connected with the box body 11 by a hinged way, which is convenient for opening and closing, so as to maintain and replace the coating member 16. The side wall of the box body 11 is provided with a lead sleeve 13, and the lead sleeve 13 is designed with a through hole 131, which is used for guiding the connection pipe to enter and pass through the coating assembly 1 stably. The lead sleeve 13 is formed with a placing position, which is a positioning area of the connection pipe when coating.

[0061] In actual operation, first, the connection pipe is placed on the placing position of the coating assembly 1 through the through hole 131 of the lead sleeve 13, and then the anticorrosive coating is supplied to the coating member 16 through the liquid inlet 15. When the connection pipe slowly passes through the coating member 16, the surface of the connection pipe is uniformly coated with a layer of anticorrosive coating.

[0067] Example 3

[0068] This embodiment is optimized on the basis of example 1.

[0069] As shown in Figures 1-7 , specifically, the embodiment provides a specific implementation of the drying assembly 2.

[0070] In the embodiment, the drying assembly 2 comprises a drying support 21 arranged at one side of the coating assembly 1 and a drying body 22 fixed on the drying support 21.

[0071] The coating box 11 is provided with a plurality of drying channels 26, and each drying channel 26 is provided with a clamping groove 23 for placing the material.

[0072] Correspondingly, a plurality of drying channels 26 are arranged in the drying body 22, and each drying channel 26 corresponds to a placing position in the coating box 11, so that each coated connecting pipe can directly enter the corresponding drying channel 26 for drying.

[0073] The drying channel 26 is internally designed with a clamping groove 23 for placing the material, and the clamping groove 23 is customized according to the specifications and shape of the connecting pipe, which can ensure that the connecting pipe is stably placed in the drying channel 26 during drying, and will not affect the drying effect due to shaking or deviation. The design of the clamping groove 23 also needs to consider the ease of placing and taking out the connecting pipe, which improves the convenience of operation. In actual operation, when the connecting pipe is coated in the coating box 11, the operator can directly move it into the corresponding drying channel 26 of the drying body 22 and place it in the clamping groove 23. Then, the hot air supply structure of the drying assembly 2 starts to work, blows hot air into the drying channel 26, and blows evenly on the surface of the connecting pipe through the ventilation structure, so that the anticorrosive coating can be quickly and uniformly cured. The close cooperation of the drying assembly 2 and the coating assembly 1, as well as the design of the clamping groove 23 in the drying channel 26, ensures that the connecting pipe can quickly and accurately enter the drying state, improving the drying efficiency.

[0074] In actual application, the clamping groove 23 in the drying channel 26 is customized according to the specifications of the connecting pipe, which can ensure that the connecting pipe is stably placed during drying, avoiding the problem of uneven drying caused by shaking or deviation.

[0075] In the embodiment, the clamping groove 23 has a first end and a second end arranged oppositely, the first end is provided with an opening and opposite to the placing position, and the second end is sealed. The first end of the clamping groove 23 is open, which is convenient for the connecting pipe to directly enter the clamping groove 23 from the opening for drying operation.

[0076] In actual use, the first end can be connected with the placing position, so that the connecting pipe in the placing position can directly enter the clamping groove 23 from the first end for drying.

[0077] In the present embodiment, the hot air supply structure comprises a heating assembly 25 and an air inlet pipe 27. The bottom of the drying channel 26 is provided with a heating cavity 24, and the heating assembly 25 is arranged in the heating cavity 24. The air inlet pipe 27 is arranged on one side of the heating cavity 24, and the air inlet pipe 27 is externally connected to an air supply device. The heating cavity 24 is in communication with the drying channel 26 through ventilation holes.

[0078] The heating assembly 25 is installed in the heating cavity 24 to generate hot air. The air inlet pipe 27 is arranged on one side of the heating cavity 24 and is externally connected to an air supply device, such as an air compressor or a blower, to provide a continuous supply of fresh air. The ventilation holes are cleverly arranged at the top or side of the heating cavity 24 to ensure that the hot air can uniformly flow into the drying channel 26 and blow on the surface of the connecting pipe. The size and shape of the ventilation holes are precisely calculated to control the flow rate and distribution of the hot air, thereby achieving the best drying effect.

[0079] In actual operation, after the connecting pipe is coated, it is placed in the clamping groove 23 of the drying channel 26. At this time, the heating assembly 25 starts to work and heats the air in the heating cavity 24 to a set temperature. At the same time, the air supply device provides fresh air to the heating cavity 24 through the air inlet pipe 27. After being heated in the heating cavity 24, the fresh air uniformly flows into the drying channel 26 through the ventilation holes and blows on the surface of the connecting pipe. Due to the design of the hot air supply structure, the hot air can quickly and uniformly cover the entire surface of the connecting pipe, so that the anticorrosive coating can quickly solidify and achieve the desired drying effect.

[0080] Example 4

[0081] This example is based on the optimization of Example 3.

[0082] As Figures 1-7 shown, in the present embodiment, the periphery of the drying channel 26 is provided with thermal insulation material.

[0083] The thermal insulation material is a high-performance thermal insulation material. This thermal insulation material has excellent heat preservation performance and can effectively prevent the heat generated during the drying process from being lost to the outside, thereby ensuring that the temperature in the drying channel 26 can quickly rise and remain stable.

[0084] The thermal insulation material of the present application can be foamed plastic, foamed glass, calcium silicate, etc., which utilizes the pores contained in the material itself for thermal insulation, as the thermal conductivity of air or inert gas in the void is very low. It can also be glass fiber, asbestos, rock wool, etc., which have a fiber structure that can form a complex heat flow path, thereby slowing down the heat transfer speed.

[0085] In addition, in the present embodiment, the width of the drying passage 26 near the card slot 23 is smaller than the width of the drying passage 26 far from the card slot 23.

[0086] The present embodiment optimizes the structure of the drying passage 26. The cross-sectional shape of the drying passage 26 is designed to have a smaller width near the card slot 23, so that the hot air can be blown more concentratedly, allowing the anticorrosive coating on the surface of the connecting pipe to be heated rapidly and begin to solidify. The width of the drying passage 26 far from the card slot 23 is designed to be larger, allowing the hot air to spread and circulate more fully in the passage, so as to ensure that the entire surface of the connecting pipe is heated uniformly. This design not only improves the drying efficiency, but also avoids the problem of uneven drying caused by uneven distribution of hot air. In addition, this variable-width drying passage 26 design also takes into account the need for energy saving. Since the hot air can be blown more concentratedly and effectively on the surface of the connecting pipe, it does not require excessive energy to heat and circulate the air, thereby achieving lower energy consumption.
