Description

Technical Field

[0001] This utility model relates to the field of powder coating production, and in particular to a filtration device for the production of environmentally friendly powder coatings. Background Technology

[0002] Environmentally friendly powder coatings are solid powder synthetic resin coatings composed of solid resin, pigments, fillers, and additives. They are insoluble in both organic matter and water. Compared with other types of coatings, they have a high recycling rate, thus effectively saving resources and reducing environmental pollution.

[0003] In the powder coating production process, the ground powder needs to be filtered and screened to remove impurities before it can be produced into powder coating. Existing filtration devices generally have internal filters to intercept impurities. However, in actual use, the filter structure is difficult to quickly screen and export different particles of the coating while ensuring filtration. This can easily lead to filter clogging, affecting filtration efficiency and making subsequent maintenance difficult.

[0004] Therefore, this utility model proposes a filtration treatment device for the production of environmentally friendly powder coatings. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-3 This utility model provides a technical solution for a filtration treatment device for the production of environmentally friendly powder coatings:

[0025] The device includes a main body 1, a bottom box 2 fixedly connected to the bottom end of the main body 1, a first collection box 3 and a second collection box 4 embedded inside the bottom box 2, a feeding assembly 5 embedded at the top end of the main body 1, a driving mechanism 6 embedded inside the feeding assembly 5, a dispersion cover 7 fixedly connected to the bottom end of the driving mechanism 6, a guide side plate 9 and a lower filter plate 10 fixedly connected inside the main body 1, a sealing assembly 8 below the feeding assembly 5, the feeding assembly 5 including a feeding cover 11 and a screening cover 12 fixedly connected, a guide port 13 opened on both sides of the screening cover 12, an upper filter plate 14 and a guide plate 15 fixedly connected inside the screening cover 12, a guide cylinder 16 fixedly connected to the bottom end of the upper filter plate 14, a vibration mechanism 20 fixedly connected below the guide plate 15, and a sealing assembly 8 including a sealing cylinder 17 and an elastic layer 18 at its top end, a connecting ring 19 fixedly connected to the top end of the elastic layer 18.

[0026] like Figure 1 As shown, the dispersion hood 7 is generally cone-shaped, with its top end fixedly connected to the bottom end of the drive mechanism 6. The drive mechanism 6 is a rotary drive mechanism. The dispersion hood 7 is also located inside the screening hood 12. The dispersion hood 7 guides and disperses the coating powder entering the feed assembly 5. The drive mechanism 6 drives the dispersion hood 7 to rotate and adjust within the screening hood 12.

[0027] When the paint powder is fed into the device, it first passes through the feeding component 5. At this time, the drive mechanism 6 rotates, which drives the dispersion hood 7 to rotate inside the screening hood 12. The rotation of the dispersion hood 7 can effectively disperse the paint powder it comes into contact with and perform preliminary separation of particles of different sizes and impurities.

[0028] like Figure 1-2 As shown, the screening hood 12 is an inverted conical hood. The feed inlet 13 is opened laterally on both sides of the opposite surface of the screening hood 12, and the feed inlet 13 is a conical opening with a larger outer diameter and a smaller inner diameter. The guide plate 15 is a conical annular plate with its surface extending outward in an arc shape. At the same time, the outer end of the guide plate 15 is located inside the feed inlet 13. The vibration mechanism 20 is a cam vibration mechanism, which is installed inside the screening hood 12 corresponding to the guide plate 15. The upper filter plate 14 is a circular filter plate, which is fixedly connected to the bottom opening of the guide plate 15. The screening hood 12, in conjunction with the feed inlet 13, achieves the effect of discharging the separated large particles and impurities outward. The guide plate 15, in conjunction with the vibration mechanism 20, achieves the effect of discharging the large particles and impurities on the upper filter plate 14 to the feed inlet 13. The upper filter plate 14 achieves the effect of screening the initially separated coating.

[0029] When the external coating comes into contact with the rotating dispersion hood 7, it is affected by centrifugal force. Some large particles and impurities are discharged outward from the feed inlet 13 as the dispersion hood 7 rotates, while other large particles and impurities are concentrated on the upper filter plate 14. At this time, the vibration mechanism 20 provided below the upper filter plate 14 is activated, which drives the arc-shaped guide plate 15 to vibrate. Then, the remaining large particles and impurities are transported along the arc-shaped guide plate 15 to the feed inlet 13 and discharged outward. The discharged large particles and impurities are finally collected in the second collection box 4, and the coating powder separated from the large particles and impurities is then filtered through the upper filter plate 14.

[0030] like Figure 1As shown, there are two sets of guide side plates 9, which are distributed on both sides of the inner side of the main body 1 of the device. The top and bottom ends of the guide side plates 9 are inclined at an angle. The lower filter plate 10 is arranged in a "V" shape and is located between the bottom of the two sets of guide side plates 9. The guide side plates 9 are used to guide and concentrate large particles and impurities discharged from the discharge port 13. The lower filter plate 10 is used to perform secondary screening of the powder coating.

[0031] like Figure 3 As shown, the sealing cylinder 17 is vertically arranged and is located directly above the lower filter plate 10. The elastic layer 18 is a corrugated rubber layer, and its bottom end is fixed and adjusted to the top end of the sealing cylinder 17. The connecting ring 19 is sleeved with the bottom end of the screening cover 12. The sealing cylinder 17 and the elastic layer 18 achieve the effect of ensuring the sealing of the filtered powder coating during delivery. The connecting ring 19 achieves the effect of connecting the sealing cylinder 17 and the screening cover 12.

[0032] After separation and removal of large particles and impurities, the paint powder enters the sealed cylinder 17 after being filtered by the upper filter plate 14, and then is filtered again by the lower filter plate 10. Finally, the filtered powder paint is collected in the first collection box 3.

[0033] The working principle of this utility model is as follows: When this device is in use, the coating is first initially dispersed by the dispersion hood 7 in the feeding component 5, and large particles and impurities are separated by centrifugal force. Then, it is initially filtered by the upper filter plate 14. Subsequently, the conveyed powder coating is sealed by the sealing cylinder 17. After being filtered again by the lower filter plate 10, the large particles and impurities are finally collected in the second collection box 4, while the filtered powder coating is collected in the first collection box 3.

[0034] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
