Description

Technical Field

[0001] This utility model relates to the field of drying equipment technology, and in particular to a drying device for powder coating production. Background Technology

[0002] Powder coating is a solid powder synthetic resin coating composed of solid resin, pigments, fillers and additives. Unlike general solvent-based coatings and water-based coatings, its dispersion medium is air.

[0003] The utility model patent with authorization announcement number CN215638564U discloses a drying device for powder coating production, including a box and a collection box fixed at the bottom of the box. The box is equipped with a drive component, which is connected to a screening component through a meshing component. When the drive component is working, it drives the screening component to move horizontally and swing, accelerating the falling of materials. The box is equipped with a drying component to dry the falling materials.

[0004] The aforementioned patent uses a heater to directly heat and dry the powder coating. Since the powder coating is distributed in a pile inside the chamber, the drying efficiency of using a single heater is generally low, and it is difficult to achieve a uniform drying effect for the powder coating. To overcome the shortcomings of the above technology, we propose a drying device for powder coating production. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a drying device for powder coating production.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A drying device for powder coating production includes a powder coating drying drum. A motor is fixedly installed on the upper side of the powder coating drying drum. A hot air pump is installed at the bottom of the powder coating drying drum. An air supply pipe is fixedly installed on the output end of the hot air pump and passes through the inside of the powder coating drying drum. An internal combined drying mechanism is installed inside the powder coating drying drum. The internal combined drying mechanism includes a structural plate and a pressure equalization chamber. Stirring strips are evenly distributed and fixedly installed on the bottom circumference of the structural plate. A vertical pipe is evenly distributed and fixedly installed on the upper circumference of the pressure equalization chamber. The vertical pipe is connected to the inside of the pressure equalization chamber. The inside of the vertical pipe is filled with sponge columns, and air outlet holes are evenly distributed on the side wall of the vertical pipe.

[0008] Furthermore, the pressure equalization chamber is connected to the upper end of the gas supply pipe, and the pressure equalization chamber is fixedly installed at the bottom of the inner side of the powder coating drying barrel.

[0009] Furthermore, the riser and the stirring bar are distributed alternately.

[0010] Furthermore, the motor output end rotates through into the powder coating drying barrel, and a rotating shaft is fixedly installed at the lower end of the motor output end. The rotating shaft is fixedly connected to the upper end of the structural disk, and several reinforcing ribs are fixedly connected between the side wall of the rotating shaft and the structural disk.

[0011] Furthermore, the upper part of the powder coating drying barrel is equipped with a feeding pipe and an exhaust pipe, and a dust filter cover is fitted on the outer end of the exhaust pipe.

[0012] Furthermore, a tapered opening is fixedly installed at the upper end of the feeding pipe, and a first solenoid valve is fixedly installed on the feeding pipe.

[0013] Furthermore, a discharge pipe is connected and installed on the lower side wall of the powder coating drying barrel, and a second solenoid valve is fixedly installed on the discharge pipe.

[0014] Furthermore, a controller is fixedly installed on the side wall of the powder coating drying barrel.

[0015] Compared with related technologies, the drying device for powder coating production proposed in this utility model has the following beneficial effects:

[0016] This invention discloses a drying device for powder coating production. Through a built-in combined drying mechanism, a motor drives a structural disk and a stirring bar mounted on the lower side of the disk to rotate. Simultaneously, a hot air pump discharges hot air through an air outlet on the side of a column fixedly mounted on the upper side of the pressure equalization chamber. This ensures the hot air is evenly distributed from within the powder coating, allowing for thorough and uniform contact. The stirring rod further accelerates the uniform mixing effect, ensuring even contact between the hot air discharged from the air outlet and the powder coating. This enhances drying efficiency and provides a more uniform drying effect, avoiding uneven drying of some powder coatings. Therefore, this invention effectively guarantees the drying effect of powder coatings and enhances its practicality. Attached Figure Description

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Reference Figure 1-5 A drying device for powder coating production includes a powder coating drying barrel 1, a motor 3 fixedly installed on the upper side of the powder coating drying barrel 1, a hot air pump 6 installed at the bottom of the powder coating drying barrel 1, an air supply pipe 7 fixedly installed on the output end of the hot air pump 6, the air supply pipe 7 passing through the interior of the powder coating drying barrel 1, and an internal combined drying mechanism 8 installed inside the powder coating drying barrel 1; the internal combined drying mechanism 8 includes a structural plate 82 and a pressure equalization chamber 85, stirring strips 84 are evenly distributed and fixedly installed on the bottom circumference of the structural plate 82, and a riser 86 is evenly distributed and fixedly installed on the upper circumference of the pressure equalization chamber 85, the riser 86 is connected to the interior of the pressure equalization chamber 85, the interior of the riser 86 is filled with sponge columns 88, and air outlets 87 are evenly distributed on the side wall of the riser 86.

[0025] With the above-mentioned arrangement, the sponge column 88 is placed inside the riser 86, preventing the powder coating from entering the riser 86 through the air outlet 87. At the same time, the sponge material has good air permeability, allowing the hot air in the riser 86 to be smoothly discharged from the air outlet 87 into the powder coating drying tank 1.

[0026] In this method, the pressure equalization chamber 85 is connected to the upper end of the gas supply pipe 7, and the pressure equalization chamber 85 is fixedly installed at the bottom of the inner side of the powder coating drying barrel 1.

[0027] With the above setup, the hot air pump 6 is started. The hot air pump 6 discharges hot air into the pressure equalization chamber 85 through the air supply pipe 7. Subsequently, the hot air enters the upper riser 86 from the pressure equalization chamber 85, and then enters the powder coating drying tank 1 from the air outlet 87, thereby drying the powder coating in the powder coating drying tank 1.

[0028] In this method, a conical nozzle 10 is fixedly installed at the upper end of the feeding pipe 9, and a first solenoid valve 11 is fixedly installed on the feeding pipe 9. A discharge pipe 12 is connected and installed on the lower side wall of the powder coating drying barrel 1, and a second solenoid valve 13 is fixedly installed on the discharge pipe 12.

[0029] With the above-mentioned setup, the cone-shaped opening 10 at the upper end of the feeding pipe 9 facilitates the addition of materials. The first solenoid valve 11 closes after the feeding is completed to prevent the powder coating from being blown out during the drying process. The discharge pipe 12 is used for the discharge of materials after drying.

[0030] In this method, a controller 2 is fixedly installed on the side wall of the powder coating drying tank 1.

[0031] By setting it up in the above manner, the controller 2 is configured to facilitate the coordinated operation of the various electrical components in this utility model.

[0032] In this configuration, the riser 86 and the agitator strip 84 are staggered.

[0033] By setting up the riser 86 and the stirring bar 84 in an alternating manner, motion interference between the riser 86 and the stirring bar 84 can be avoided when the riser 86 rotates.

[0034] In this method, the output end of motor 3 rotates through the inside of powder coating drying barrel 1, and a rotating shaft 81 is fixedly installed at the lower end of the output end of motor 3. The rotating shaft 81 is fixedly connected to the upper end of structural disk 82, and several reinforcing ribs 83 are fixedly connected between the side wall of rotating shaft 81 and structural disk 82.

[0035] By setting up the rib plate 83 in the above manner, the structural connection strength between the rotating shaft 81 and the structural disk 82 is improved.

[0036] In this method, the upper part of the powder coating drying barrel 1 is connected to two feed pipes 9 and exhaust pipes 4, and a dust filter hood 5 is fitted on the outer end of the exhaust pipe 4.

[0037] With the above-mentioned configuration, the exhaust pipe 4 is used for exhaust during the drying process, while the dust filter hood 5 installed on its outer end prevents dust from entering the powder coating drying barrel 1, and also prevents the powder coating from being discharged from the exhaust pipe 4 during the exhaust process.

[0038] The working principle of the drying device for powder coating production provided by this utility model is as follows:

[0039] In use, the powder coating to be dried is added into the feeding pipe 9 through the conical opening 10. The powder coating enters the powder coating drying tank 1 through the feeding pipe 9. After the feeding is completed, the first solenoid valve 11 is closed, and then the motor 3 and the hot air pump 6 are started simultaneously. The first motor 3 drives the structural plate 82 and the stirring bar 84 fixedly installed on its lower side to rotate. At the same time, the hot air pump 6 injects hot air into the pressure equalization chamber 85 through the air supply pipe 7. Then, the hot air is discharged into the powder coating through the air outlet 87 on the side wall of the upper riser 86. Under the uniform stirring action of the stirring bar 84, the discharged hot air is fully in contact with the inside of the powder coating. The hot air then dries the powder coating. The generated water vapor is discharged upward with the hot air and then discharged into the outside of the powder coating drying tank 1 through the exhaust pipe 4. The powder coating is dried evenly and quickly, and it is highly practical.

[0040] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
