Description

Technical Field

[0001] The utility model belongs to the technical field of drying equipment, in particular to a drying device for coating. Background Art

[0002] The coating production line mainly includes pre-treatment equipment, powder spraying equipment, paint spraying equipment, drying equipment, heat source equipment, electronic control system and conveying equipment.

[0003] Traditional hot air circulation heating devices are widely used in drying equipment. These devices typically use a high-power burner to generate flames, which burn in a sealed heat exchange chamber. High-power hot air circulation fans then transport the hot air through pipes into the drying chamber. While this method can achieve drying tasks to a certain extent, it also has several problems, as follows:

[0004] 1. The heat conversion rate is low. The length of the heat exchange chamber will cause a large amount of heat to be lost during the transmission process, resulting in a serious waste of energy and seriously affecting the heating effect;

[0005] 2. Due to the high power, the power and gas consumption of these devices is also a problem that cannot be ignored, which increases the cost of operation;

[0006] 3. Due to the uneven distribution of hot air, the temperature in the drying room is often uneven, which directly affects the drying quality and efficiency;

[0007] 4. When a single high-power burner is damaged, the drying device will not be able to heat up and cannot complete the drying task. It can only work after it is repaired.

[0008] Therefore, it is necessary to design a coating drying device with uniform temperature, high energy utilization efficiency and convenient maintenance. Summary of the Invention

[0009] To address the above technical issues, this utility model proposes a coating drying device that effectively solves the problem of uneven temperature distribution through the provision of an air outlet chamber and a sealing plate. This design allows heat to flow upward during air outlet, and the lower edge of the sealing plate effectively prevents excessive heat loss, thereby saving electricity, reducing power consumption and high gas consumption, and improving operating cost-effectiveness.

[0010] The technical solution of the utility model is:

[0011] A drying device for coating, comprising a drying chamber and an air outlet chamber arranged at at least one end of the drying chamber;

[0012] The air outlet chamber is located below and communicates with the drying chamber. A baffle extending into the air outlet chamber is provided at the end of the drying chamber, with the lower edge of the baffle lower than the bottom wall of the drying chamber. The provision of the air outlet chamber and baffle effectively guides the flow of hot air, improving temperature uniformity within the drying chamber and thereby enhancing drying efficiency and quality. The baffle design also helps prevent excessive heat loss, saving energy. Furthermore, the position and structure of the air outlet chamber help optimize the hot air flow path, reduce energy loss, and improve thermal efficiency.

[0013] Preferably, the ratio of the vertical length of the baffle plate to the vertical length of the drying chamber is between 1.25 and 1.66. This optimized baffle length helps further improve the flow and distribution of hot air, making the temperature in the drying chamber more uniform, further improving drying efficiency and quality. This design also helps reduce potential uneven heating and cooling within the drying chamber.

[0014] Preferably, a support mechanism is provided on at least one side of the drying chamber, and the support mechanism includes a support plate.

[0015] Preferably, the middle portion of the support plate is parallel to the bottom surface of the drying chamber, and the end portion of the support plate is configured as an inclined surface, and the inclined direction of the end portion of the support plate is toward the ground.

[0016] Preferably, a fence is provided on the outside of the support plate, and the fence is slidably connected to a storage box.

[0017] Preferably, a slide is provided on the fence, a pulley is provided at the bottom of the storage box, and the pulley is slidably provided in the slide.

[0018] Preferably, it also includes a heating mechanism and a conveying mechanism connected to the drying chamber.

[0019] The heating mechanism consists of a linear array of radiant tubes mounted on the bottom wall of the drying chamber and a linear array of burners mounted on the outer wall of the drying chamber. Each burner corresponds to a specific radiant tube, and the burner ports are connected to the tube inlets. A support plate facilitates burner maintenance. A controller electrically connected to each burner provides accurate information on its operating status, facilitating quick identification of problems during maintenance, thereby improving equipment reliability and maintenance efficiency.

[0020] Compared with the prior art, the present invention has the following advantages and effects:

[0021] 1. The problem of uneven temperature distribution is effectively solved by setting up the air outlet chamber and the sealing plate. This design allows the heat to flow upward when the air is discharged, and the lower edge of the sealing plate can effectively prevent excessive heat loss, thereby saving electricity, reducing power consumption and high gas consumption, and improving operating cost efficiency;

[0022] 2. The support plate makes it easier for workers to repair the burner. The controller is electrically connected to each burner, allowing accurate information on the working conditions of each burner, making it easier to quickly locate problems during maintenance, thereby improving equipment reliability and maintenance efficiency.

[0023] 3. The maintenance equipment and tools of the staff can be placed in the storage box, making the storage and management of maintenance equipment and tools more convenient. Through the setting of pulleys and slides, the storage box can be easily moved to the burner that needs maintenance, which improves the maintenance efficiency and makes it easier for the staff to reach the fault location of the burner. The staff can go directly to the corresponding burner for maintenance, saving working time and improving work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] In order to enable those skilled in the art to better understand the present invention, the present invention will be further described in conjunction with specific implementation methods.

[0031] Example 1:

[0032] like Figure 1~Figure 2 As shown, the utility model provides a drying device for coating, comprising a drying chamber 1 and an air outlet chamber 3 provided at at least one end of the drying chamber 1;

[0033] The air outlet chamber 3 is located below the drying chamber 1 and is connected to the drying chamber 1. A sealing plate 10 extending to the air outlet chamber 3 is provided at the end of the drying chamber 1, and the lower edge of the sealing plate 10 is lower than the bottom wall of the drying chamber 1. By providing the air outlet chamber 3 and the sealing plate 10, the flow of hot air can be effectively guided, and the temperature uniformity in the drying chamber 1 can be improved, thereby improving the drying efficiency and quality. At the same time, the design of the sealing plate 10 helps to prevent excessive heat loss and save energy. In addition, the position and structure of the air outlet chamber 3 help to optimize the flow path of hot air, reduce energy loss, and improve thermal efficiency. The provision of air outlet chambers 3 at both ends of the drying chamber 1 or the provision of air outlet chambers 3 at one end of the drying chamber 1 are both within the scope of protection of the patent of this utility model.

[0034] The ratio of the vertical length of the baffle plate 10 to the vertical length of the drying chamber 1 is between 1.25 and 1.66. This optimized length design of the baffle plate 10 further improves the flow and distribution of hot air, making the temperature within the drying chamber 1 more uniform, further improving drying efficiency and quality. This design also helps reduce potential uneven heating and cooling within the drying chamber.

[0035] Working principle: When in use, the burner heats the radiant tube and heats the drying chamber 1 to solve the uneven temperature distribution. The small-power, large-number burners are combined with the gas outlet chamber 3 and the baffle 10 to make the heat go upwards when the gas is discharged. The lower edge of the baffle 10 can effectively prevent excessive heat loss, which can save electricity and effectively solve the technical problems of high power and gas consumption and increased operating costs.

[0036] Example 2:

[0037] For Example 2 of the present utility model, Figure 3 、 Figure 4 、 Figure 5 Note that, descriptions of parts that are the same as those in Example 1 are omitted and are given the same reference numerals.

[0038] like Figure 3 、 Figure 4 、 Figure 5 As shown, in the coating drying device according to the present invention, a support mechanism is provided on at least one side of the drying chamber 1 , and the support mechanism includes a support plate 4 .

[0039] The middle portion of the support plate 4 is parallel to the bottom surface of the drying chamber 1 , and the end portion of the support plate 4 is arranged as an inclined surface, and the inclined direction of the end portion of the support plate 4 is toward the ground.

[0040] A fence 43 is provided on the outside of the support plate 4 , and a storage box 42 is slidably connected to the fence 43 .

[0041] A slide 44 is provided on the fence, and a pulley 45 is provided at the bottom of the storage box 42 , and the pulley 45 is slidably provided in the slide 44 .

[0042] The system also includes a heating mechanism and a transport mechanism connected to the drying chamber 1. The support plate 4 facilitates burner maintenance. The controller, electrically connected to each burner, accurately monitors the operating status of each burner, facilitating rapid problem location during maintenance, thereby improving equipment reliability and maintenance efficiency.

[0043] The conveying mechanism is a chain conveying mechanism, which is a mature existing technology and will not be described in detail here.

[0044] Optionally, the embodiment also includes a controller electrically connected to the burner. The controller is a prior art for understanding the working conditions of each burner. Since it is a mature prior art, it will not be described in detail here.

[0045] The setting of the support plate 4 makes it convenient for the staff to repair the burner, and the controller is electrically connected to each burner, so that the working status of each burner can be accurately known. In this way, when repairing, the specific burner to be repaired can be clearly known. When the staff is repairing, the design of small power and large number of burners can solve the problem that when a single high-power burner is damaged, the drying device will not be able to heat and cannot complete the drying task;

[0046] Furthermore, the maintenance equipment and tools of the staff can be placed in the storage box 42, and the storage box 42 is pushed by the rotation of the pulley 42, which makes it convenient for the staff to turn over the maintenance equipment and tools, thereby improving the practicality of the device.
