Abstract
Description
Technical Field
[0001] The utility model generally relates to the technical field of container production and manufacturing equipment, and more specifically relates to a drying system and a drying room for containers. Background Art
[0002] Containers made of metal materials, especially steel, usually need to be coated with one or more layers of paint on the surface of the material to protect the material from corrosion or rust.
[0003] Traditional coatings are usually oil-based coatings containing organic solvents / thinners. During the coating process and the process of coating film formation and curing, organic solvents / thinners will evaporate, causing serious pollution and endangering the health of coating workers. Water-based coatings with water as a solvent are significantly less harmful to the environment and human body than oil-based coatings, but water-based coatings are not easy to dry than oil-based coatings. When water-based coatings are selected as primer coatings for containers, if the water-based coatings cannot dry within the specified time, the metal on the surface of the container will react with the water in the coating to produce oxidation, causing flash rust on the surface of the container. Moreover, the topcoat can only be sprayed when the primer is completely dry, otherwise flash rust will also appear on the surface of the container, seriously affecting product quality.
[0004] The drying device of the related art is usually designed to blow hot air into the interior of the container to dry the interior of the container, and rely on the hot air overflowing from the interior or normal ventilation to dry the outer wall of the container. Since the paint film thickness of each part of the exterior of the container is different, and the plate thickness of each part of the container is inconsistent, the heat absorption is inconsistent, resulting in inconsistent temperature rise, which causes inconsistent drying time for each part, especially the outer wall, front wall and corner column, which are not easy to dry, which may affect the execution of the subsequent process or in order to ensure the subsequent process, it is necessary to increase the drying process or increase the drying time to meet the demand, affecting production efficiency and causing cost increase.
[0005] Therefore, it is necessary to provide a drying system and a drying room for containers to at least partially solve the above problems. Utility Model Content

[0060] Hereinafter, specific embodiments of the present invention will be described in more detail with reference to the accompanying drawings. These drawings show representative embodiments of the present invention and are not intended to limit the present invention.
[0061] refer to Figures 1 to 11 The utility model provides a drying system for a container and a drying room 100 having the drying system.
[0062] The drying system includes a drying channel, an internal drying device 110 and an external drying device 120. Drying stations 107 and a transfer track 106 are arranged in the drying channel. Specifically, at least two drying stations 107 are arranged at intervals along the extension direction of the drying channel. The transfer track 106 is also arranged along the extension direction, so that the container 200 to be dried can be transferred along the transfer track 106 to different drying stations 107 for drying.
[0063] refer to Figure 2 and Figure 7 , the interior of the container 200 is dried by the internal drying device 110. The internal drying device 110 includes a pit 111, which is arranged below each drying station 107. A ventilation plate is laid at the pit opening of the pit 111, and the ventilation plate is provided with ventilation holes 114. The pit 111 is connected to the air source device 130 through the pipeline 109. The air source device 130 blows air to the interior of the container 200 to be dried through the pipeline 109, the pit opening and the ventilation holes 114 to increase the drying speed of the interior of the container 200. It can be understood that the bottom of the container 200 to be dried in this article is not closed.
[0064] refer to Figure 2 and Figure 7 , the outside of the container 200 (hereinafter referred to as the container 200) is dried by the external drying device 120. The external drying device 120 includes an air supply channel, which is arranged near the drying station 107. Specifically, the air supply channel is suitable for being arranged to the circumferential outside and / or the top of the container 200. The air supply channel is used to be connected to the wind source device 130, and the outer wall of the air supply channel is provided with at least one air outlet to blow air to the circumferential outside and / or the top of the container 200.
[0065] The external drying device 120 is mainly used to blow air and dry the outer surface of the container 200. Specifically, the circumferential outer portion of the container 200 includes the side and end portions of the container 200. The side portions of the container 200 are generally provided with structures such as side walls, side doors and / or side columns, the ends of the container 200 are generally provided with structures such as end walls, end doors and / or corner columns, and the top of the container 200 is provided with a top wall.
[0066] Preferably, multiple air outlets are arranged at intervals along the extension direction of the air supply channel to achieve uniform blowing of air to the target position of the container 200, thereby improving the drying efficiency and the drying quality of the container 200. The air outlets can also be evenly distributed in an array on the outer wall of the air supply channel.
[0067] When the container 200 is located at the drying station 107, the air supply channel is located outside the container 200. Specifically, the air supply channel can be arranged around the container 200, so that the wind source device 130 can blow and dry the outer surface of the side wall and the outer surface of the end wall of the container 200 through the air supply channel and the air outlet. The air supply channel can also be arranged on the top of the container 200, so that the wind source device 130 can blow and dry the outer surface of the top wall of the container 200 through the air supply channel and the air outlet.
[0068] The air supply channel can be connected to the air source device 130 through the pipeline 109, for example. The internal drying device 110 and the external drying device 120 can be connected to the output port of the same air source device 130 through the pipeline 109 (see Figure 7 The internal drying device 110 and the external drying device 120 may also be connected to the output ports of different wind source devices 130, respectively. By adjusting the output parameters of different wind source devices 130 (such as the pressure, temperature, flow rate, etc. of the outlet air), the drying operation may be performed on the inside and outside of the container 200, respectively. The wind source device 130 may be a fan, or may be a heating fan.
[0069] Preferably, an air outlet device 125 may be provided at the air outlet. The air outlet device 125 includes an air outlet pipe 125a, one end of which is connected to the air outlet, and the other end of which faces the container 200 to be dried, for example, the outer surface of the side wall, the end, the corner column position and the outer surface of the top wall of the container 200, so as to facilitate pressurization to improve the drying efficiency.
[0070] Furthermore, the cross-sectional area of the end of the air outlet 125a connected to the air outlet is larger than the cross-sectional area of the other end of the air outlet 125a (toward the container 200). The change of the cross-sectional area of the air outlet 125a further increases the pressure of the outlet air to improve the drying efficiency.
[0071] The shape of the air outlet can be configured as a round hole or a strip hole. Figure 4 The air outlet is configured as a circular hole, and correspondingly, the air outlet device 125 can be configured as a cylindrical exhaust cylinder 108 .
[0072] See also Figure 3 , Figure 5 , Figure 6 , Figure 7 , the air outlet is constructed as a strip hole, see Fig.10 and Fig.11 The air outlet device 125 further includes a base 125b, which is fixedly connected to the air supply channel. Fig.10 As shown, the base 125b includes a connecting ear plate, which is connected to the air supply channel through the connecting ear plate. The air outlet pipe 125a is hinged to the base 125b and communicates with the air outlet through the base 125b. In this way, the air outlet of the air outlet pipe 125a can be easily adjusted to achieve a better drying effect on the container 200. According to an example, the air outlet pipe 125a can be configured to be pivotable relative to the base 125b around a rotation axis (such as Fig.10 In other examples not shown in the present invention, the air outlet pipe 125a may also be configured to be universally rotatable relative to the base 125b.
[0073] Reference Figures 1 to 7 In this embodiment, the drying channel includes a first channel 104 and a second channel 105 connected to each other (see Figure 1 and Figure 2 The extending direction of the first channel 104 is parallel to the width direction D2 of the container 200 (see Figure 2 ), the extension direction of the second channel 105 is parallel to the length direction D1 of the container 200 (see Figure 7 ).
[0074] In the first channel 104, the container 200 moves along its width direction D2 on the transfer track 106, thereby moving to different drying stations 107. In the second channel 105, the container 200 moves along its length direction D1 on the transfer track 106, thereby moving to different drying stations 107. Figure 2 Three transfer tracks 106 are arranged at intervals in the first channel 104 along the length direction D1 of the container 200, so that the drying system can be suitable for drying containers 200 of different sizes: for small-sized containers 200, only two adjacent transfer tracks 106 can be used for transportation; for large-sized containers 200, three transfer tracks 106 can be used for transportation.
[0075] According to one example, the external drying device 120 includes at least one of a first air supply channel 121, a second air supply channel 122, and a third air supply channel 123. The first air supply channel 121 is adapted to be arranged outside the length direction D1 of the container 200 to blow air to the side and corner columns of the container 200. The second air supply channel 122 is adapted to be arranged on the top of the container 200 to blow air to the top of the container 200. The third air supply channel 123 is adapted to be arranged outside the width direction D2 of the container 200 to blow air to the end and corner columns of the container 200.
[0076] like Figure 3 As shown in FIG. 1 , in the first channel 104, the first air supply channel 121 is arranged below the transfer track 106 and between two adjacent drying stations 107. This will not affect the movement of the container 200 along the transfer track 106. In addition, along the extension direction of the first channel 104 (i.e., the width direction D2 of the container 200), the first air supply channel 121 is provided with two air outlets at intervals, so that the containers 200 on both sides can be dried simultaneously through one first air supply channel 121.
[0077] When the container 200 moves to the drying station 107, the first air supply channel 121 is located outside the container 200. At this time, the internal drying device 110 can supply air to the inside of the container 200 through the ventilation holes 114, and the first air supply channel 121 can blow air to the side walls and corner columns of the container 200 through the air outlets. Along the length direction D1 of the container 200, a plurality of air outlets are arranged at intervals on the first air supply channel 121.
[0078] The second channel 105 extends along the length direction D1 of the container 200, and the first air supply channel 121 can be arranged at both sides of the container 200 without affecting the movement of the container 200 along the length direction D1. Figure 6 and Figure 7 As shown in FIG. 1 , in the second passage 105, the first air supply passage 121 is extended along the height direction D3 of the container 200 and arranged on both sides of the drying station 107, and a plurality of air outlets are arranged at intervals along the height direction D3 to the first air supply passage 121. When the container 200 moves to the drying station 107, the first air supply passage 121 can blow air to the two side wall surfaces of the container 200.
[0079] like Figure 2 and Figure 4As shown in FIG. 1 , in the first channel 104, the second air supply channel 122 is arranged at the top of the container 200 and extends along the length direction D1 of the container 200. A plurality of air outlets are arranged at intervals on the second ventilation channel along the width direction D2. When the container 200 moves to the drying station 107, the second air supply channel 122 can blow air to the outer surface of the top wall of the container 200 through the air outlet.
[0080] like Figure 6 and Figure 7 As shown, in the second passage 105, when the container 200 moves to the drying station 107, the second air supply passage 122 is arranged at the top of the container 200 and extends along the width direction D2 of the container 200. A plurality of air outlets are arranged at intervals on the second air supply passage 122 along the width direction D2. When the container 200 moves to the drying station 107, the second air supply passage 122 can blow air to the outer surface of the top wall of the container 200 through the air outlets.
[0081] refer to Figure 4 At the end portion in the length direction D1 close to the container 200, the second air supply channel 122 is further connected to the third air supply channel 123, and the third air supply channel 123 extends along the width direction D2 of the container 200. Along the width direction D2, a plurality of air outlets are arranged at intervals on the third air supply channel 123. When the container 200 moves to the drying station 107, the third air supply channel 123 can blow air to the end wall and corner column of the container 200 through the air outlet device.
[0082] Figure 4 The third air supply channel 123 is located at the end and top of the container 200. Figure 2 and Figure 5 The third air supply channel 123 may also be disposed on the side of the end of the container 200. Specifically, Figure 5 The third air supply channel 123 extends along the width direction D2 of the container 200 . The third air supply channel 123 is provided with a plurality of air outlets on the outer wall facing the container 200 . The plurality of air outlets are distributed in an array.
[0083] Preferably, at least two of the first air supply channel 121, the second air supply channel 122 and the third air supply channel 123 are connected to form an integrally formed component. Figure 4 In the embodiment, the external drying device 120 includes a second air supply passage 122 and a third air supply passage 123 connected as one body. Figure 6 and Figure 7 In the embodiment, the external drying device 120 includes a first air supply channel 121 and a second air supply channel 122 which are connected as one body.
[0084] like Figure 1 and Figure 2As shown, the present invention also provides a drying room 100, including the drying system of the present invention.

The entrance 102 of the drying room 100 is arranged at the head end of the first channel 104, the tail end of the first channel 104 is connected to the head end of the second channel 105, and the tail end of the second channel 105 is the exit 103 of the drying room 100. That is, the container 200 to be dried is transported from the entrance 102 into the first channel 104, moves along the transmission track 106 in the first channel 104 to the tail end, and then enters the second channel 105. After being dried by the drying system in the first channel 104 and the second channel 105, the dried container 200 is output from the exit 103.
