Description

Technical Field

[0001] This utility model relates to the field of heat circulation technology for paint booths, specifically a hot air circulation device for paint booths used in garbage bins. Background Technology

[0002] Trash cans are common garbage storage containers in daily life. They are mostly made of metal or plastic. During the manufacturing process of trash cans, they need to be painted. Especially for metal trash cans, after painting, a baking process is required to make the paint more stable and fixed on the surface of the trash can.

[0003] During the painting process, trash cans need to be placed on a painting rack. Traditional painting racks only provide support for the trash cans. Since the trash cans are stationary on the rack and there is no air circulation around them, uneven heating and poor painting efficiency are likely to occur. To address this, we propose a hot air circulation device for trash can painting booths. Utility Model Content

[0004] This invention provides a hot air circulation device for a paint booth for garbage bins, which allows the heat inside the paint booth to circulate around the garbage bin, avoiding uneven heating of the garbage bin and solving the problems mentioned in the background art.

[0005] The technical solution of this utility model is implemented as follows: A hot air circulation device for a paint booth for garbage bins includes a support frame, with support rods at the four corners of the support frame, and several support bars for supporting the garbage bins spaced apart at the top of the support frame. Second air pipes are provided on both sides of the top of the support frame, and at least one first air pipe is provided at the bottom of the support frame. Several nozzles are provided on the top of the first and second air pipes. The first air pipe blows air towards the bottom of the garbage bin, and the second air pipes blow air towards both sides of the garbage bin. One end of each of the first and second air pipes is connected to a second connecting pipe. The second connecting pipe is connected to the outlet of a high-pressure blower through a third connecting pipe. The inlet of the high-pressure blower is connected to the paint booth through a guide pipe.

[0006] Preferably, the bottom of each support rod is provided with a traveling wheel.

[0007] Preferably, the high-pressure blower is located outside the paint booth, and an air inlet pipe is connected to the air outlet of the high-pressure blower. The air inlet pipe extends into the paint booth, and the end of the air inlet pipe is detachably connected to the third connecting pipe.

[0008] Preferably, there are multiple support frames arranged in layers along the support rods.

[0009] Preferably, two adjacent second connecting pipes are connected by a first connecting pipe.

[0010] Preferably, each support frame is provided with multiple brackets below it, with both ends of the brackets connected to the support frame, and the first air blowing pipe is set on the bracket.

[0011] Preferably, the first and second air blowers are each provided with a plurality of U-shaped pipe clamps.

[0012] Compared with the prior art, when the high-pressure blower is working, the hot air in the paint booth is guided to the third connecting pipe through the air guide pipe. Then the hot air is blown from each nozzle around the trash can, so that the air around the trash can is fluid and the heat in the paint booth can circulate around the trash can, thus avoiding uneven heating of the trash can.

Detailed Implementation

[0019] The technical solution of this utility model will be clearly and completely described below with reference to its embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] Reference Figures 1 to 4This utility model provides a technical solution: a hot air circulation device for a paint booth for garbage bins, including a support frame 11. Multiple support frames 11 are arranged in a multi-layered manner. The four corners of each support frame 11 are connected to support rods 1. The support rods 1 and the multi-layered support frames 11 form a whole. Each support rod 1 has a wheel 16 at its bottom, which is a braked omnidirectional wheel, allowing the hot air circulation device to be easily moved and positioned. In use, the support frame 11 is pushed into the paint booth 12. At least one hot air circulation device is installed in the paint booth 12; when multiple hot air circulation devices are used, they are arranged at intervals within the paint booth 12.

[0021] Furthermore, the top of the support frame 11 is provided with several support bars 4 at intervals. The support bars 4 are used to support the trash cans 8. That is, when in use, the trash cans 8 are placed on the support bars 4. Since the support frame 11 is multi-layered, multiple trash cans 8 can be placed at one time.

[0022] The support frame 11 has a second air pipe 6 on each side of the top, and several nozzles 5 on the top. The second air pipe 6 blows air towards both sides of the trash can 8, which can generate air flow around the trash can 8, allowing the heat in the paint booth to circulate around the trash can 8, thus avoiding uneven heating of the trash can 8.

[0023] At least one first air pipe 3 is provided at the bottom of the support frame 11, and several nozzles 5 are also provided at the top of the first air pipe 3. The nozzles 5 on the first air pipe 3 blow air towards the bottom of the garbage bin 8. Multiple brackets 7 are provided below each support frame 11. The two ends of the brackets 7 are connected to the support frame 11 respectively. The first air pipe 3 is set on the brackets 7. The brackets 7 not only support the first air pipe 3, but also, due to the presence of the brackets 7, there is a certain gap between the first air pipe 3 and the support bar 4, so as to avoid the first air pipe 3 being too close to the bottom of the garbage bin 8.

[0024] The first air duct 3 and the second air duct 6 are both connected at one end to the second connecting pipe 9, allowing the airflow entering the second connecting pipe 9 to exit from each of the first air duct 3 and each of the second air duct 6. Since the support frame 11 is multi-layered, adjacent second connecting pipes 9 are connected by a first connecting pipe 2. One of the second connecting pipes 9 is connected to the outlet of the high-pressure blower 14 via a third connecting pipe 10. In this embodiment, the bottommost second connecting pipe 9 can be connected to the high-pressure blower 14 via the third connecting pipe 10; however, any second connecting pipe 9 can be connected to the third connecting pipe 10.

[0025] like Figure 3As shown, the high-pressure blower 14 is located outside the paint booth 12 to avoid interference from high temperatures. An air inlet pipe 15 is connected to the air outlet of the high-pressure blower 14, extending into the paint booth 12. The air inlet pipe 15 is detachably connected to the end of the third connecting pipe 10 via a detachable pipe joint. Thus, when the hot air circulation device needs to be moved outside the paint booth 12, it is only necessary to separate the third connecting pipe 10 from the air inlet pipe 15 to move the hot air circulation device outside the paint booth 12.

[0026] The air inlet of the high-pressure blower 14 is connected to the paint booth 12 via the air duct 13. The end of the air duct 13 is installed on the top of the paint booth 12 to prevent dust from the bottom of the paint booth 12 from entering the air duct 13. An insulation layer, such as an insulation cotton sleeve, is provided on the air duct 13 to prevent heat conduction to the outside. The specific working process is as follows: when the high-pressure blower 14 is working, it guides the hot air in the paint booth 12 through the air duct 13 to the third connecting pipe 10. The third connecting pipe 10 distributes this high-pressure airflow to each of the first blowing pipes 3 and each of the second blowing pipes 6, and then blows it from the nozzles 5 around the trash can 8, allowing the air around the trash can 8 to circulate.

[0027] Furthermore, the first air pipe 3 and the second air pipe 6 are respectively provided with multiple U-shaped pipe clamps 17. The two ends of the U-shaped pipe clamps 17 are fastened to the bracket 7 and the support frame 11 by bolts, thereby fixing the first air pipe 3 and the second air pipe 6.

[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
