Description

Technical Field

[0001] The utility model relates to the field of paint processing, in particular to a drying device for raw materials of waterborne epoxy primer paint. Background Technique

[0002] Epoxy paint resin and curing agent are both dispersions. After the two components are mixed, they can be emulsified in water and consist of two components: the base material is a hydrophobic epoxy resin, and the curing agent is a hydrophilic amine curing agent. The amine curing agent used can act as an emulsifier and a crosslinking agent. Water-soluble coatings are often also called electrophoretic coatings, that is, after the resin is dissolved in water, a uniform colloidal solution is formed. Usually, the raw materials need to be dried before use to remove the excess water inside.

[0003] However, at present, the drying of epoxy paint resin raw materials mostly directly uses heating to accelerate the evaporation of water, and the drying efficiency of the raw materials piled up at the bottom is low. Content of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides a drying device for raw materials of waterborne epoxy primer paint, which solves the problems mentioned in the above background.

[0006] As a further scheme of the utility model: a partition board is installed on the side surface of the drying bin above the stirring rod, and a support frame is installed inside the rotating connecting rod at the end far from the driving motor.

[0007] As a further scheme of the utility model: a cover is arranged above the drying bin, an air outlet is installed on the upper surface of the cover close to one side of the driving motor, a heating mechanism is installed at the end of the drying bin far from the driving motor, and an air inlet is installed at one end of the drying bin on the side above the heating mechanism.

[0012] As a further solution of the present utility model: The air inlet is connected to the drying bin in a through manner, and the heating mechanism is electrically connected to the stirring rod.

[0013] Compared with the prior art, the beneficial effects of the present utility model are:

[0014] 1. With the setting of the hollow groove inside the mixing blade and the blocking of the partition plate on the side surface of the drying bin, a speed difference of the raw materials with controlled disturbance can be achieved during stirring, realizing the uniform mixing of the raw materials inside, and facilitating the evaporation of water vapor inside the raw materials by heat.

[0015] 2. The driving hydraulic cylinder controls the overall upward lifting of the rotating connecting rod.

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0023] As Figures 1-5 shown, this embodiment provides a drying device for waterborne epoxy primer raw materials, including a drying bin 1. Two driving motors 3 are installed at one end of the drying bin 1. The ends of the two driving motors 3 are connected to a stirring rod 301 inside the drying bin 1. Mixing blades 302 are arrayed on the outer side of the stirring rod 301. The mixing blades 302 are fixedly connected to the stirring rod 301. A hollow groove 303 is opened inside the mixing blade 302. The hollow groove 303 runs through the mixing blade 302 as a whole. When the stirring rod 301 rotates to drive the mixing blade 302 to stir the internal raw materials, the setting of the hollow groove 303 inside the mixing blade 302 can control the speed difference of the disturbed raw materials during stirring, achieving the purpose of increasing the mixing effect. An activity ear plate 402 is installed at the lower end of the drying bin 1. A rotating connecting rod 401 is installed inside the activity ear plate 402 near one end of the driving motor 3. A rotating shaft is installed between the rotating connecting rod 401 and the activity ear plate 402. A hydraulic cylinder 4 is installed at the lower end of the rotating connecting rod 401.

[0024] As Figures 2-5 shown, in this embodiment, a partition plate 101 is installed on the side surface of the drying bin 1 above the stirring rod 301. The partition plate 101 is fixedly connected to the drying bin 1. A support frame 5 is installed inside the rotating connecting rod 401 at the end far from the driving motor 3. A blanking hole is opened on the lower surface of the drying bin 1 near one end of the support frame 5. A cover 2 is arranged above the drying bin 1. The cover 2 is clamped with the drying bin 1. An air outlet 8 is installed on the upper surface of the cover 2 near one side of the driving motor 3. The air outlet 8 is connected to the cover 2 in a through manner. A heating mechanism 6 is installed at the end of the drying bin 1 far from the driving motor 3. The heating mechanism 6 is electrically connected to the stirring rod 301. An air inlet 7 is installed on one side end of the drying bin 1 above the heating mechanism 6. The air inlet 7 is connected to the drying bin 1 in a through manner. The air inlet 7 is connected to the drying bin 1 in a through manner.

[0025] The working principle of the present utility model is as follows: When in use, the raw materials are filled into the interior of the drying bin 1 as a whole, and the cover 2 is covered on the upper surface of the drying bin 1 as a whole. By connecting the air inlet 7 to a hot air source, the driving motor 3 is used to control the stirring rod 301 to rotate as a whole. When the stirring rod 301 rotates, it drives the mixing blades 302 to stir the raw materials inside. With the cooperation of the hollow grooves 303 inside the mixing blades 302 and the blocking of the partition plate 101 on the side surface of the drying bin 1, a speed difference of the disturbed raw materials can be controlled during stirring, achieving uniform mixing of the raw materials inside. The hot air output from the air inlet 7 is used to evaporate the water vapor inside and is taken out from the position of the air outlet 8. At the same time, the heating mechanism 6 provided as a whole can be used to heat the stirring rod 301, and the raw materials inside are heated and evaporated under the action of heat transfer. After stirring for a period of time, the driving hydraulic cylinder 4 is used to control the rotating link 401 to lift upward as a whole. The rotating link 401 will rotate with the movable ear plate 402, and at the same time, the support frame 5 at the other end will also rotate with the movable ear plate 402, lifting one end of the drying bin 1 as a whole, so that while stirring, the raw materials move towards the position of the drying bin 1 near the support frame 5 to discharge the materials.
