[0002] Spraying drying equipment is used in industrial production to accelerate the drying and curing of coatings. Traditional drying equipment has high energy consumption, while waste heat recovery drying equipment can significantly reduce energy consumption, improve energy efficiency, and reduce production costs by recovering and utilizing the waste heat generated during the drying process.

[0003] During the use of the drying equipment, the workpieces to be dried are usually placed inside the drying equipment. However, the operating space inside the drying equipment is small, so collisions are likely to occur during the hanging process, which can damage the workpieces and affect the quality of spraying and drying. Utility Model Content

[0004] This disclosure relates to a waste heat recovery drying device for spraying, which solves the problem mentioned in the background art that the internal operating space of the drying device is small, which makes it easy for collisions to occur during the hanging process, causing damage to the processed parts and affecting the quality of spraying and drying.

[0005] This utility model discloses a waste heat recovery drying device for spraying, which is achieved by the following specific technical means: This utility model provides a waste heat recovery drying device for spraying, including: a drying box, the drying box being rectangular in shape, and a connecting column being installed inside the drying box; a transmission base rotating above the inside of the drying box; the drying box also includes: a waste heat recovery component, the waste heat recovery component being fixedly installed on the top of the drying box; a transmission motor, the transmission motor being fixedly installed in the middle of the top of the drying box; and a transmission connection between the shaft of the transmission motor and the top of the transmission base.

[0006] As a preferred embodiment of this utility model, the drying oven further includes: a drying assembly, wherein the number of drying assemblies is set to two, and the drying assemblies are symmetrically fixedly installed on both sides of the drying oven; and a door, which rotates to the front end of the drying oven.

[0007] As a preferred embodiment of this utility model, the connecting column further includes: a connecting support column, the number of which is set to five sets, and the connecting support column is integrally set on the outside of the connecting column; a spraying hook, the number of which is set to five sets, and the spraying hook is symmetrically fixedly installed at the bottom of the connecting support column; and a fixing hook, the fixing hook is fixedly installed on the top of the connecting support column located at the top of the connecting column.

[0008] As a preferred embodiment of this utility model, the connecting column further includes: a limiting block, the limiting block being rectangular in shape, and two limiting blocks being symmetrically and integrally disposed on the top of the connecting support column located at the top of the connecting column; and two limiting grooves, the limiting grooves being symmetrically opened in the middle of both sides of the limiting block.

[0009] As a preferred embodiment of this utility model, the transmission base further includes: a connecting hook, wherein the number of connecting hooks is set to two, and the connecting hooks are symmetrically fixedly installed at the bottom of the transmission base; the connecting hooks are connected to the fixed hooks; a connecting shell, which is fixedly installed at the bottom of the transmission base; a sliding block, which slides inside the connecting shell; and a spring is installed between the connecting shell and the sliding block.

[0010] As a preferred embodiment of this utility model, the transmission base further includes: a toggle block, the number of toggle blocks being set to two, the toggle blocks being symmetrically and integrally disposed in the middle of both sides of the sliding block; a limiting slot, the number of limiting slots being set to two, the limiting slots being symmetrically opened at the bottom of the sliding block; and a limiting protrusion, the number of limiting protrusions being set to two, the limiting protrusions being symmetrically and integrally disposed inside the limiting slot.

[0011] Compared with the prior art, the present invention has the following beneficial effects: When drying the spray-coated parts, the operator needs to detach the fixed hook from the connecting hook, hang the parts to be processed one by one on the spray hook, and then accurately hang the fixed hook back on the connecting hook. The transmission motor is then started to drive the transmission base to rotate slowly and steadily. The rotation of the transmission base causes the connecting hanging column to rotate as well, and the parts on the connecting hanging column also rotate together, ensuring that every part is heated evenly.

[0012] Once the connecting column is successfully attached to the connecting hook of the transmission base via the fixed hook, the operator engages the limiting slot with the limiting block. The connecting column will then be restricted by the sliding block, keeping it vertical and effectively preventing it from tilting. If the connecting column is tilted, the workpiece will not be in uniform contact with the hot air during rotation, resulting in some areas being over-dried while others are under-dried, thus affecting the overall drying quality of the workpiece. This method facilitates mounting while ensuring that each workpiece is dried in a uniform hot air environment, guaranteeing the consistency and stability of the drying effect.

[0019] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.

[0020] Example: As attached Figure 1 To be continued Figure 5 As shown: This utility model provides a waste heat recovery drying device for spraying, comprising: a drying box 1, which is rectangular in shape and has a connecting column 2 hanging inside; a transmission base 3 rotating on the top of the drying box 1; the drying box 1 also includes: a waste heat recovery component 101, which is fixedly installed on the top of the drying box 1 and is a mature existing technology capable of recovering and utilizing the waste heat from drying; a transmission motor 102, which is fixedly installed in the middle of the top of the drying box 1; the shaft of the transmission motor 102 is connected to the top of the transmission base 3; two drying components 103 are provided, which are symmetrically fixedly installed on both sides of the drying box 1; and a box door 104, which rotates to the front end of the drying box 1; the drying components 103 are mature existing technology and are capable of delivering hot air for drying operations.

[0021] The connecting pillar 2 also includes: a connecting support column 201, with five sets of connecting support columns 201 integrally installed on the outside of the connecting pillar 2; a spraying hook 202, with five sets of spraying hooks 202 symmetrically fixedly installed at the bottom of the connecting support column 201; a fixing hook 203, fixedly installed at the top of the connecting support column 201 located at the top of the connecting pillar 2; a limiting block 204, with two rectangular blocks 204 symmetrically integrated at the top of the connecting support column 201 located at the top of the connecting pillar 2; and two limiting grooves 205 symmetrically opened on the middle of both sides of the limiting block 204.

[0022] The transmission base 3 further includes: two connecting hooks 301, which are symmetrically fixedly installed at the bottom of the transmission base 3; the connecting hooks 301 are connected to the fixed hooks 203; a connecting housing 302, which is fixedly installed at the bottom of the transmission base 3; a sliding block 303, which slides inside the connecting housing 302; a spring is installed between the connecting housing 302 and the sliding block 303; two actuating blocks 304, which are symmetrically and integrally set in the middle of both sides of the sliding block 303; two limiting slots 305, which are symmetrically opened at the bottom of the sliding block 303; and two limiting protrusions 306, which are symmetrically and integrally set inside the limiting slots 305.

[0023] The specific usage and function of this embodiment are as follows: When drying the sprayed workpiece, the fixed hook 203 is detached from the connecting hook 301, the connecting column 2 is detached from the drying device, the workpiece is hung on the spray hook 202, and then the fixed hook 203 is hung back on the connecting hook 301. At this time, the waste heat recovery component 101, the drive motor 102, and the drying component 103 are started. The drying component 103 drives the drive base 3 to rotate, which in turn drives the connecting column 2 to rotate, causing the workpiece on the connecting column 2 to rotate. The drying component 103 then dries the workpiece. During the continuous drying process, the waste heat recovery component 101 can recover and transfer the heat generated in the drying chamber 1 back into the drying chamber 1, thereby completing the drying operation.

[0024] After the connecting column 2 is hung on the connecting hook 301 of the transmission base 3 via the fixed hook 203, the connecting column 2 is restricted by the sliding block 303 by the contact and engagement of the limiting slot 305 and the limiting block 204. This ensures that the connecting column 2 is in a vertical state after being hung, thereby preventing the connecting column 2 from being tilted and causing uneven drying.
