Description

Technical Field

[0001] This utility model relates to the field of metal product processing technology, specifically to a metal product drying equipment. Background Technology

[0002] The metal products industry includes the manufacturing of structural metal products, metal tools, containers and metal packaging containers, stainless steel and similar daily-use metal products. When processing metal products, it is often necessary to paint their outer surface. In order to speed up the curing of the paint on the metal products, they need to be dried. The existing drying process generally involves placing the metal products directly in a drying oven or drying room.

[0003] The distance between the workpieces on different shelves and the air outlet of the drying mechanism in existing metal product drying equipment varies significantly, which seriously affects the uniformity of hot air distribution. The upper workpieces are prone to local overheating because they are too close to the air outlet, while the lower workpieces suffer from poor drying effect due to the attenuation of hot air. In addition, most existing metal product drying equipment is equipped with a heat recovery mechanism, but the filter plate connection mechanism in the heat recovery mechanism is relatively cumbersome. The filter plates are generally fixed by bolts. This rigid connection structure requires special tools to disassemble. Therefore, a new technical solution needs to be designed to solve this problem.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1: Please refer to again Figure 1-4This utility model provides a metal product drying device, including a drying chamber 100. A chamber door 110 is hinged to one side of the drying chamber 100. A gas heater 120 is fixedly connected to one side of the drying chamber 100. A gas supply pipe 121 is fixedly connected to the top of the gas heater 120. One end of the gas supply pipe 121 is connected to the drying chamber 100. Two rotating discs 130 are rotatably connected to the inner wall of the drying chamber 100. Three shelves 140 are rotatably connected between the inner sides of the two rotating discs 130. The bottom of 140 has a through hole 141, and the through holes 141 are arranged in sequence. A motor 150 is fixedly connected to one side of the drying chamber 100. One end of the power output shaft of the motor 150 passes through the drying chamber 100 and extends into the inner cavity of the drying chamber 100. The other end of the power output shaft of the motor 150 is fixedly connected to the rotating wheel 130. A vacuum pump 160 is fixedly connected to one side of the gas heater 120. A recovery pipe 161 is fixedly connected to one side of the vacuum pump 160. The recovery pipe 161 is fixedly connected to the filter pipe 200.

[0022] Specifically, by activating the gas heater 120 to absorb and heat the outside gas, the heated gas is then transported to the drying chamber 100 through the gas supply pipe 121 to heat and dry the metal products placed on the racks inside the drying chamber 100. At the same time, the motor 150 is activated to drive the rotating disk 130 connected to it to rotate, causing multiple racks 140 installed on the rotating disk 130 to move from bottom to top as the rotating disk 130 rotates, so that multiple racks 140 can make uniform contact with the air outlet of the gas supply pipe 121, thereby improving the drying effect on the metal products on the racks 140.

[0023] Example 2: Please refer to again Figure 1-4 A filter tube 200 is fixedly connected to one side of the drying chamber 100. A mounting bracket 210 is snapped onto the outside of the filter tube 200. A filter plate 220 is fixedly connected to the bottom of the mounting bracket 210. The bottom of the filter plate 220 extends into the inner cavity of the filter tube 200. An installation chamber 230 is fixedly connected to the outside of the filter tube 200. Two installation slots 231 are opened inside the installation chamber 230. A positioning tenon 240 is slidably connected to the inner cavity of the installation slot 231. One end of the positioning tenon 240 passes through the installation chamber 230 and extends into the interior of the mounting bracket 210. A connecting plate 241 is fixedly connected to the other end of the positioning tenon 240. The top of the connecting plate 241 extends to the top of the installation chamber 230. A support plate 250 is fixedly connected to the top of the connecting plate 241. A compression spring 260 is embedded in the inner cavity of the installation slot 231.

[0024] Specifically, by starting the vacuum pump 160, the hot air in the drying chamber 100 is filtered through the filter pipe 200 and then transported back to the gas heater 120 through the recovery pipe 161 to recover heat efficiency and reduce energy consumption. When it is necessary to clean the filter plate 220, the connecting plate 241 connected to the support plate 250 is moved by dragging the support plate 250. After the compression spring 260 is compressed, the positioning latch 240 installed on the connecting plate 241 is released from fixing the mounting bracket 210, and the compression spring 260 is compressed. Move the device into the mounting slot 231, then pull up the mounting bracket 210 to remove the filter plate 220 at the bottom of the mounting bracket 210 from the filter tube 200. After cleaning the filter plate 220, reinsert the filter plate 220 into the filter tube 200. Then, release the support plate 250 to reset the compression spring 260 that was squeezed by the positioning latch 240, and extend it to push the connecting plate 241 to move, so that the positioning latch 240 installed on the connecting plate 241 is reinserted into the mounting bracket 210, thus fixing the mounting bracket 210 and the filter plate 220 at the bottom.

[0025] Working principle: After absorbing and heating the outside gas by activating the gas heater 120, the heated gas is transported to the drying chamber 100 through the gas supply pipe 121 to heat and dry the metal products placed on the racks in the drying chamber 100. At the same time, the motor 150 is activated to drive the rotating disk 130 connected to it to rotate, so that multiple racks 140 installed on the rotating disk 130 move from bottom to top with the rotation of the rotating disk 130, so that multiple racks 140 can make uniform contact with the air outlet of the gas supply pipe 121, thereby improving the drying effect on the metal products on the racks 140.

[0026] By activating the vacuum pump 160, the hot air in the drying chamber 100 is filtered through the filter pipe 200 and then transported back to the gas heater 120 via the recovery pipe 161 for heat recovery, reducing energy consumption. When the filter plate 220 needs cleaning, the connecting plate 241 connected to the support plate 250 is moved by dragging the support plate 250. This compresses the pressure spring 260, causing the positioning latch 240 on the connecting plate 241 to release its fixation to the mounting bracket 210. The pressure spring 260 is then compressed and moved. The filter plate 220 at the bottom of the mounting bracket 210 is removed from the filter tube 200 after the mounting bracket 210 is pulled up into the mounting slot 231. After cleaning the filter plate 220, the filter plate 220 is reinserted into the filter tube 200. Then, the support plate 250 is released to reset the compression spring 260 that was squeezed by the positioning clip 240, and the extension pushes the connecting plate 241 to move, so that the positioning clip 240 installed on the connecting plate 241 is reinserted into the mounting bracket 210, thus fixing the mounting bracket 210 and the filter plate 220 at the bottom.
