Description

Technical Field

[0001] This utility model belongs to the field of dryer technology, specifically relating to an anti-scaling scraper. Background Technology

[0002] In industries such as chemical, food, and pharmaceutical, scraper devices are commonly used in equipment such as disc dryers and coating machines to remove material from the surface of discs or rollers. However, for high-viscosity, easily crystallizing, or particulate materials, material residue easily accumulates on the scraper blade and at the connection between the blade head and the mounting frame. Long-term accumulation forms scale, leading to decreased scraping efficiency, accelerated equipment wear, and even safety hazards. Existing scraper structures are mostly set at fixed intervals, making it difficult to adapt to different material characteristics, resulting in low material removal efficiency. Therefore, it is essential to design a movable, anti-scaling scraper. Utility Model Content

[0003] The purpose of this invention is to provide an anti-scaling scraper for existing devices, in order to solve the problems mentioned in the background art.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an anti-scaling scraper, comprising a mounting base, several scraper assembly fixing plates, a sliding groove, a scraper seat, a transmission rod, a blade clamping plate, a scraper, and a driving mechanism. The side of the mounting base is a right-angled trapezoid. Several scraper assembly fixing plates are evenly fixedly connected to one side of the inclined surface of the mounting base. The sliding groove is opened above the scraper assembly fixing plates. The scraper seat is slidably connected in the sliding groove. The transmission rod is threadedly connected to the scraper seat. The transmission rod is provided with first and second threads in opposite directions at intervals. The blade clamping plate is installed in the scraper seat. The scraper is riveted in the blade clamping plate. The driving mechanism includes a drive motor, a rotating rod, a drive gear, and a driven gear. The driven gear is fixedly connected to the end of the transmission rod.

[0005] This utility model further illustrates that baffles are fixedly connected to the upper part of the scraper assembly fixing plate near both sides of the mounting base.

[0006] This utility model further explains that the sliding groove is a single strip on the scraper assembly fixing plate near both sides of the mounting base, while the sliding grooves on the other scraper assembly fixing plates are symmetrically arranged in pairs.

[0007] The present invention further illustrates that a positioning plate is fixedly connected above the scraper assembly fixing plate by a screw, and the positioning plate is located between the two scrapers.

[0008] The present invention further illustrates that both the driving gear and the driven gear are bevel gears, and the driving gear and the driven gear are meshed together.

[0009] The present invention further illustrates that the rotating rod is fixedly connected to the drive motor via a coupling, and the drive gear is sleeved on the rotating rod.

[0010] The present invention further illustrates that a mounting bracket is riveted above one of the scraper assembly fixing plates near one side of the baffle.

[0011] This utility model further illustrates that the rotating rod bearing is connected inside the mounting bracket.

[0012] Compared with the prior art, the beneficial effects achieved by this utility model are: This utility model,

[0013] By setting up a drive mechanism to drive the transmission rod to rotate, and using the first and second threads on the transmission rod in opposite directions, the two scraper seats on the same scraper assembly fixed plate can move towards or away from each other, thereby precisely adjusting the distance and contact pressure between the scraper and the drying tray. This allows the scraping force to be dynamically adjusted according to the material viscosity, crystallization characteristics, etc., ensuring that the blade surface and the surface of the drying tray are in the best contact state, significantly improving the scraping efficiency of high viscosity and easily crystallizing materials, and reducing material residue and scaling.

[0023] The following detailed, non-limiting description of the present invention, in conjunction with preferred embodiments and accompanying drawings, is provided. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0024] Please see Figure 1-7 The present invention provides a technical solution: an anti-scaling scraper, including a mounting base 1 for connecting the scraper to the dryer. The side of the mounting base 1 is a right-angled trapezoid. Several scraper assembly fixing plates 2 are uniformly fixedly connected to one side of the inclined surface of the mounting base 1. Baffles 3 are fixedly connected above the scraper assembly fixing plates 2 near the two sides of the mounting base 1 to achieve the effect of shielding the scraper.

[0025] refer to Figure 2 The upper part of the scraper assembly fixing plate 2 is provided with a sliding groove 4. Among them, the two upper sliding grooves 4 of the scraper assembly fixing plates 2 near the two sides of the mounting base 1 are individually provided, and the other upper sliding grooves 4 of the scraper assembly fixing plates 2 are symmetrically provided with respect to the scraper assembly fixing plates 2. The inside of the sliding groove 4 is slidably connected to the scraper seat 5, which plays a positioning role. The scraper seat 5 is connected to the transmission rod 6 by thread.

[0026] Further, refer to Figure 4-5 The transmission rod 6 is provided with several first threads 61 and second threads 62 at equal intervals, and the directions of the first threads 61 and second threads 62 are opposite. By rotating the transmission rod 6, the two scraper seats 5 on the same scraper group fixing plate 2 can be moved towards each other or in opposite directions.

[0027] The scraper holder 5 has a blade clamp 7 installed inside, and a scraper 8 is riveted inside the blade clamp 7 to perform the main material scraping operation.

[0028] refer to Figure 2-3 and Figure 6-7A positioning plate 9 is fixedly connected to the top of the scraper assembly fixing plate 2 by a screw, and the positioning plate 9 is located between the two scrapers 8, which plays a positioning role for the scrapers 8. A mounting bracket 10 is riveted to the top of one of the scraper assembly fixing plates 2 near the side baffle 3. A drive mechanism is installed inside the mounting bracket 10. The drive mechanism includes a drive motor 13, a rotating rod 11, a drive gear 12 and a driven gear 14.

[0029] The rotating rod 11 is connected to the inside of the mounting bracket 10 by a bearing, and two moving gears 12 are sleeved on the rotating rod 11. One end of the rotating rod 11 is fixedly connected to the drive motor 13 through a coupling, so that the rotation of the rotating rod 11 can be achieved by starting the drive motor 13.

[0030] Furthermore, the driven gear 14 is disposed on one side of the drive gear 12. Both the drive gear 12 and the driven gear 14 are bevel gears, and the drive gear 12 and the driven gear 14 are meshed together. The transmission rod 6 is fixedly connected to the middle of the driven gear 14, so that the rotation of the drive gear 12 will drive the driven gear 14 to rotate, thereby further realizing the rotation of the driven rod 6.

[0031] In this embodiment, based on the characteristics of the material and the drying process requirements, the drive motor 13 is started to rotate the driven rod 6. The scraper seat 5 on it will drive the two scrapers 8 on the same scraper group fixing plate 2 to move, adjusting the distance between them. The scrapers 8 on both sides will move closer to or further away from the adjacent baffle 3, thereby determining the contact pressure between the scraper body and the disc, ensuring that the scraper 8 blade surface and the disc surface are in the best contact state. When the disc of the dryer rotates to dry the material, the scraper 8 effectively reduces the residue and scale on the blade surface and connecting parts. It is suitable for scraping high-viscosity and easily crystallizing materials, and has the advantages of convenient cleaning and low maintenance cost.
