Description

Technical Field

[0001] This utility model relates to the field of powder granulation technology, specifically a rotary slant disc granulator. Background Technology

[0002] In the pet supplies manufacturing industry, cat litter, as a core consumable in the daily lives of pet cats, directly impacts product competitiveness through its molding quality and efficiency. Currently, the industry commonly uses rotary disc granulators for cat litter molding. The working principle of this equipment is as follows: cat litter raw materials (such as bentonite, tofu fiber, plant starch, etc.) are placed in an inclined rotating disc. The disc rotates continuously, causing the powder to move along the inner wall of the disc under the action of centrifugal force and gravity. At the same time, a certain amount of water is sprayed onto the powder, causing the powder particles to adhere to each other and gradually agglomerate, ultimately forming cat litter granules that meet the particle size requirements.

[0003] In this forming process, the scraper has two functions: first, to scrape off the powder adhering to the inner wall of the turntable, preventing raw material accumulation; and second, to change the trajectory of the powder within the turntable by blocking the moving powder, forcing the powder to tumble and accelerating pellet formation. However, the scraper structure used in existing rotary disc granulators is generally a single piece. Due to the fixed angle and single scraping path, the scraper is prone to uneven powder accumulation and insufficient tumbling, which in turn affects the pellet forming speed and uniformity. Utility Model Content

[0004] The purpose of this invention is to provide a rotary slant disc granulator that improves granulation efficiency by setting the scraper to a split, adjustable structure.

[0005] This utility model adopts the following technical solution: a rotary slant disc granulator, comprising: A turntable, arranged at an angle and rotatably mounted on a frame; The power mechanism, connected to the turntable, is used to drive the turntable to rotate around its axis. The scraper assembly is attached to the bottom surface of the turntable; A support beam, fixed to the frame, is used to support the scraper assembly; The scraper assembly includes multiple rotatably mounted split baffles, each of which is provided with a locking element for positioning the angle of the split baffle.

[0006] Furthermore, the scraper assembly also includes a main board; The motherboard is perpendicular to the turntable; a rectangular through slot is opened on the bottom side of the motherboard, and the split baffles are arranged in the through slot.

[0007] A baffle is fixedly connected to the bottom side of the motherboard, and the baffle is attached to the bottom surface of the turntable.

[0008] The baffle has slopes on both sides.

[0009] The motherboard has a threaded hole on its upper surface that connects to the long through slot, the split baffle has a square hole that passes through the split baffle, and the baffle has a light hole. The threaded hole, the square hole, and the light hole are arranged coaxially. The locking element includes: The square main rod is fitted into the square hole in the split baffle; The stud is fixed to the upper end of the main rod; the stud is threaded into the threaded hole on the main board. The optical axis is fixed at the lower end of the main rod; the optical axis is coaxial with the stud, and the optical axis is rotatably fitted into the optical hole on the stop bar.

[0010] The stud has a cap at its upper end and a fastening nut is installed on the stud.

[0011] The motherboard is fixed to the support beam by a connector; The connector includes: The U-shaped frame is fixedly connected to the upper side of the motherboard at both ends; U-bolts are upside down on the support beam; both ends of the U-bolts are fixedly connected to the U-shaped frame.

[0012] The U-shaped frame has slots at both ends, and the motherboard has corresponding slots on its upper side. The slots of the U-shaped frame are engaged in the slots of the motherboard and fixed together with connecting bolts.

[0013] A positioning groove is formed on the support beam; The upper side of the U-shaped frame fits into the positioning groove on the lower side of the support beam; The U-bolts are snapped upside down into the positioning grooves on the upper side of the support beam.

[0014] The beneficial effects of this invention are as follows: the scraper assembly is divided into multiple evenly distributed separate baffles. The powder no longer falls along a single path along the entire scraper, but instead tumbles and falls independently from under each separate baffle, forming a multi-path, dispersed motion trajectory. This avoids localized powder accumulation, allowing all powder to fully contact the turntable and participate in tumbling, reducing the problem of small particles agglomerating into large clumps or excessively different particle sizes, ultimately improving the particle forming speed. The tilt angle of each separate baffle can be adjusted independently; for wet powder that easily sticks to the tray, the baffle tilt angle can be increased to enhance the scraping effect; for dry powder that is easily broken, the angle can be decreased to reduce the impact force of scraping. At the same time, the angle adjustment can also indirectly change the width of the powder drop, enabling one device to adapt to multiple types of powder (cat litter raw materials) and improve the versatility of the equipment.

[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1: like Figure 1As shown, this utility model provides a rotary slant disc granulator, mainly comprising a turntable 1, a power mechanism 2, and a scraper assembly 3. The turntable 1 is inclined and rotatably mounted on the frame. The power mechanism 2 is located on the back side of the turntable 1 and is used to drive the turntable 1 to rotate. The scraper assembly 3 is fixed to the frame by a support beam 4, and the scraper assembly 3 is attached to the bottom surface of the turntable 1 to block the powder on the turntable 1, causing the powder to fall and tumble, and quickly form granules.

[0025] Combination Figures 1 to 3 As shown, in this embodiment, the scraper assembly 3 includes a main board 32 with a rectangular elongated groove on its bottom side. A retaining strip 33 has latches at both ends and is located on the bottom side of the main board 32. The latches at both ends of the retaining strip 33 are welded to the bottom sides of the main board 32, forming a rectangular frame structure with the elongated groove. The main board 32 is perpendicular to the turntable 1, and the retaining strip 33 is attached to the bottom surface of the turntable 1. The retaining strip 33 has slopes on both sides to better scrape off powder from the bottom surface of the turntable 1.

[0026] Combined Figures 4 to 6 As shown, the scraper assembly 3 also includes multiple rotatably mounted split baffles 31. The split baffles 31 are evenly distributed and installed in the elongated slot of the main plate 32, with the upper and lower edges of the split baffles 31 fitting against the upper and lower sides of the elongated slot. The split baffles 31 are installed by locking members 5, which can adjust the tilt angle of the split baffles 31 and lock the split baffles 31 after adjustment.

[0027] The locking component 5 includes a stud 51, a main rod 52, and an optical shaft 53, which are coaxially fixed in sequence. The stud 51 has a cap at its upper end and a fastening nut 54 is installed thereon. The main rod 52 is square, and the optical shaft 53 is a smooth round rod. A threaded hole communicating with a long through slot is opened on the upper end face of the main plate 32, and the stud 51 is threaded into the threaded hole on the main plate 32. A square hole is opened on the split baffle 31, and the main rod 52 is fitted into the square hole on the split baffle 31. The main rod 52 and the split baffle 31 cannot rotate relative to each other. A light hole is opened on the stop bar 33, and the optical shaft 53 is fitted into the light hole on the stop bar 33. The optical shaft 53 can rotate freely in the light hole on the stop bar 33.

[0028] Working principle: The powder is placed in turntable 1, and the power mechanism 2 drives turntable 1 to rotate. When turntable 1 rotates, the powder tumbles in turntable 1; by spraying a certain amount of water onto the powder, small particles are formed. During the tumbling process of the powder, the particles gradually become larger, forming particles of the required size.

[0029] In this embodiment, the scraper assembly is used to scrape off the powder adhering to the turntable 1 and improve the tumbling effect. In this embodiment, the scraper assembly is designed as a split baffle 31. This allows the powder to tumble and fall from each split baffle 31, resulting in a more uniform powder distribution and improved particle forming speed. Before operation, the stud can be rotated by loosening the fastening nut, thereby adjusting the angle of each split baffle 31. The overall falling width can be adjusted for different powders to adapt to the particle forming of different powders.

[0030] Example 2: Based on the above embodiment one, combined with Figures 1 to 3 As shown, the support beam 4 is fixed on the frame, and the scraper assembly 3 is fixed to the support beam 4 through the connector 6.

[0031] The connector 6 includes a U-shaped frame 61 with slots at both ends. Two slots are provided on the upper side of the main board 32 in the scraper assembly 3. The slots of the U-shaped frame 61 engage with the slots of the main board 32. Connecting bolts 63 are inserted through the slots and slots to fix the U-shaped frame 61 to the main board 32. A positioning groove is provided on the support beam 4. The upper side of the U-shaped frame 61 fits into the positioning groove on the lower side of the support beam 4 to prevent axial movement of the U-shaped frame 61 relative to the support beam 4. U-bolts 62 are inverted and inserted into the positioning groove on the upper side of the support beam 4. The two threaded ends of the U-bolts 62 pass through the U-shaped frame 61 and are tightened with nuts.
