Description

Technical Field

[0001] This utility model relates to a disc feeder, specifically a suspended disc feeder suitable for high-hardness materials. Background Technology

[0002] Disc feeders are widely used mechanical devices for continuous quantitative feeding of granular materials. Their core principle is to achieve stable material conveying through the friction between a rotating disc and the material. However, when conveying high-hardness materials, the wear on the disc surface from the material particles is severe, and material jamming between the disc and the housing can easily cause the disc to overflow and trip, increasing the difficulty of operation and maintenance. Existing disc feeder equipment cannot effectively improve the conveying efficiency of high-hardness materials, nor can it effectively solve the aforementioned problems. Utility Model Content

[0003] The purpose of this invention is to provide a suspended disc feeder suitable for high-hardness materials, so as to solve the problems of rapid wear of the disc feeder surface and easy material jamming when conveying high-hardness solid granular materials, and further improve the conveying efficiency of the equipment.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A suspended disc feeder suitable for high-hardness materials includes a housing. A power mechanism is fixed to the bottom of the housing and is connected to a disc inside the housing. Multiple lower scrapers are evenly arranged circumferentially on the bottom of the disc, with gaps between the lower scrapers and the housing. A retaining ring is provided at the top edge of the disc, and an upper scraper is provided above the retaining ring and fixed to the side wall of the housing. A feed inlet is provided at the top of the housing, located above the center of the disc. A discharge outlet is also provided at the bottom of the housing, located beside the disc.

[0006] Furthermore, a protective sleeve is fixed to the feed inlet, and the lower edge of the protective sleeve is lower than the upper edge of the retaining ring.

[0007] Furthermore, a strip screen is fixed on the side wall of the housing, and the strip screen is located in the gap between the retaining ring and the side wall of the housing, with a gap width of 80~120mm.

[0008] Furthermore, the power mechanism includes a motor and a reducer fixed to the bottom of the outer side of the housing. The output end of the motor is connected to the input end of the reducer, and the output end of the reducer is connected to the disc.

[0009] Compared with the prior art, the present invention has the following beneficial effects:

[0010] This disc feeder can reduce the wear on the disc surface caused by high-hardness materials and effectively reduce the frequency of large particles mixed in with the material jamming the disc feeder, thereby achieving long-term stable operation of the equipment without maintenance.

[0014] The present invention will be further explained below with reference to the accompanying drawings.

[0015] like Figure 1-2 As shown, a suspended disc feeder suitable for high-hardness materials includes a housing 5. A power mechanism 10 is fixed at the bottom of the housing 5. The power mechanism 10 is connected to a disc 4 rotatably disposed inside the housing 5. Multiple lower scrapers 6 are evenly arranged circumferentially at the bottom of the disc 4, and there is a gap between the lower scrapers 6 and the housing 5, with a gap width not exceeding 5mm. A retaining ring 3 is provided at the top edge of the disc 4, and an upper scraper 1 is provided above the retaining ring 3. The upper scraper 1 is fixed to the side wall of the housing 5. A strip screen 9 is also fixed on the side wall of the housing 5. The strip screen 9 is located in the gap between the retaining ring 3 and the side wall of the housing 5, with a gap width of 80~120mm, preferably 100mm. A feed inlet 7 is opened at the top of the housing 5, and the feed inlet 7 is located above the center of the disc 4. A protective sleeve 2 is fixed on the feed inlet 7, and the lower edge of the protective sleeve 2 is lower than the upper edge of the retaining ring 3. A discharge outlet 8 is also opened at the bottom of the housing 5, and the discharge outlet 8 is located beside the disc 4.

[0016] The power mechanism 10 includes a motor and a reducer fixed to the bottom of the outer side of the housing 5. The output end of the motor is connected to the input end of the reducer, and the output end of the reducer is connected to the disc 4.

[0017] The working process of this utility model is as follows:

[0018] Taking the conveying of quartz particles with a particle size of less than 20mm as an example, the material enters the housing 5 of the disc feeder through the feed inlet 7 and falls onto the disc 4. As the disc 4 rotates, the accumulated material moves to the upper scraper 1 connected to the housing 5 and is scraped into the discharge outlet 8.

[0019] Because the lower edge of the casing 2 is lower than the upper edge of the retaining ring 3, it prevents materials and potentially entrained large particles from entering the gap between the disc 4 and the shell 5, thus avoiding jamming of the disc 4 and causing it to stop or fall directly into the discharge port 8. At the same time, the retaining ring 3 causes materials to accumulate on the surface of the disc 4, and the accumulated material layer protects the disc surface, effectively reducing wear. After the accumulated material overflows from the surface of the disc 4, particles with a diameter smaller than the gap of the bar screen 9 fall through the bar screen 9 into the gap between the disc and the shell, and are scraped into the discharge port 8 by the scraper 6 at the bottom of the disc. Particles with a diameter larger than the gap of the bar screen 9 that overflow from the surface of the disc 4 are isolated on the bar screen, which effectively reduces the frequency of large-diameter materials jamming and causing the disc feeder to stop.

[0020] This invention protects the disc surface and reduces abrasion by adding a retaining ring and upper scraper to the disc, ensuring material always accumulates on it. Simultaneously, the design of a bar screen structure with a lower scraper prevents large particles from entering the gap between the disc feeder's surface and the housing, reducing the disc jamming failure rate. Practical application has verified that when conveying materials with a Mohs hardness of 7 or higher (quartz particles with a diameter of less than 20mm), it effectively extends the disc surface maintenance and replacement cycle by more than three times.
