Description

Technical Field

[0001] The utility model relates to the technical field of disk feeders, and particularly relates to a large-particle disk feeder. Background Art

[0002] A disk feeder is an auxiliary equipment of transportation machinery. The feeding particle size of the disk feeder is 0mm - 150mm. Therefore, it is most suitable to transport materials with a large specific gravity by the disk feeder. The disk feeder is generally used in occasions such as ore dressing, sintering and smelting, and feeds materials accurately and evenly. Compared with other conveying equipment, the disk feeder has a small installation space and stable use. However, the disk feeder has the following problems: First, the transmission device (double-row self-aligning roller bearings at both ends) on the disk feeder is relatively high, occupying a large space and being inconvenient for use and maintenance; second, it cannot smoothly transport large-particle materials (0mm - 250mm). Therefore, there is an urgent need for a large-particle disk feeder to solve the above problems. Content of the Utility Model

[0003] In order to solve the technical problems that the transmission device on the disk feeder is relatively high and it cannot smoothly transport large-particle materials, the utility model provides a large-particle disk feeder, which uses cylindrical roller bearings to replace the double-row self-aligning roller bearings at both ends on the traditional disk feeder. The setting of the cylindrical roller bearings greatly shortens the height of the transmission mechanism, has a small occupied space, a simple transmission structure and convenient maintenance; in addition, the utility model can also smoothly transport large-particle materials.

[0004] The utility model provides a large-particle disk feeder, which includes a frame, a transmission mechanism and a feeding mechanism. The feeding mechanism is rotationally arranged on the frame through the transmission mechanism. The feeding mechanism includes a receiving disk and a hollow cylinder. A disk gear is arranged at the lower part of the receiving disk. The transmission mechanism includes cylindrical roller bearings arranged on the frame, and the cylindrical roller bearings are rotationally connected with a shaft. The center of the disk gear is fixedly connected with the top of the shaft. A feeding cone is arranged at the upper part of the receiving disk. The hollow cylinder is arranged on the frame, and the bottom of the hollow cylinder contacts the top wall of the receiving disk. The feeding cone is located inside the hollow cylinder. An outlet is arranged on the hollow cylinder.

[0005] Further, a sealing plate is fixedly connected between the bottom of the hollow cylinder and the receiving disk. The outer periphery of the upper part of the receiving disk is in a stepped structure. The bottom of the hollow cylinder contacts the upper surface of the stepped structure on the receiving disk. One end of the sealing plate is fixedly connected with the bottom of the hollow cylinder, and the other end of the sealing plate contacts the lower surface of the stepped structure on the receiving disk. The sealing plate can prevent powder and broken selenium ingots from leaking between the bottom of the hollow cylinder and the receiving disk to pollute the factory site.

[0006] Furthermore, a baffle is inclinedly arranged on the inner wall of the hollow cylinder. The baffle is located on the side of the discharge port, and a reinforcing rib is fixedly connected between the baffle and the hollow cylinder. The baffle can block large particle materials, further facilitating the falling of large particle materials from the discharge port.

[0007] Furthermore, a feed hopper is inclinedly arranged on the outer wall of the hollow cylinder. The feed hopper is located below the discharge port. After the large particle materials fall from the discharge port onto the feed hopper, they enter the next working station.

[0008] Furthermore, a plurality of scraping blades are uniformly arranged at the top of the blanking cone. The plurality of scraping blades are arranged along the circumferential direction of the blanking cone. The function of the scraping blades is to scrape and break the outer packaging bag of the ton bag.

[0009] Furthermore, a driving mechanism is further included. The driving mechanism includes a motor and a speed reducer arranged on the frame. The output shaft of the motor is in transmission connection with the input end of the speed reducer, and the output end of the speed reducer is in transmission connection with the disc gear. When the motor starts, it drives the speed reducer to operate. After the speed reducer operates, it drives the disc gear to rotate.

[0010] Furthermore, a plurality of upper support columns are uniformly arranged on the upper part of the frame. A plurality of L-shaped fixing blocks are uniformly arranged on the outer wall of the hollow cylinder. Each L-shaped fixing block is fixedly connected to the upper support column.

[0011] Furthermore, the transmission mechanism further includes a bearing seat arranged at the lower part of the frame. The bottom of the cylindrical roller bearing is arranged in the bearing seat. The cylindrical roller bearing is sleeved on the bearing seat, and the bearing seat supports and fixes the cylindrical roller shaft.

[0012] Compared with the prior art, the utility model has the following technical effects:

[0013] Firstly, the cylindrical roller bearing is used to replace the two-end self-aligning roller bearings on the traditional disc feeder. The setting of the cylindrical roller bearing greatly shortens the height of the transmission mechanism. It occupies a small space, has a simple transmission structure, and is convenient for maintenance. Secondly, large particle materials can be smoothly conveyed. The large particle materials fall from the ton bag into the area between the receiving disc, the hollow cylinder and the blanking cone. The setting of the blanking cone enables the large particle materials to fall along the blanking cone. After the receiving disc rotates, it will drive the large particle materials in the area to rotate. The large particle materials are displaced. When the large particle materials move to the discharge port, the large particle materials fall from the discharge port to the next working station. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The present utility model will be further described below in conjunction with the drawings and specific embodiments.

[0027] Such as Figures 1 to 4As shown in the figure, a large-particle disk feeder includes a frame 1, a transmission mechanism 2, and a feeding mechanism 3. The feeding mechanism 3 is rotatably arranged on the frame 1 through the transmission mechanism 2. The feeding mechanism 3 includes a receiving disk 31 and a hollow cylinder 32. A disk gear 311 is arranged at the lower part of the receiving disk 31. The transmission mechanism 2 includes a cylindrical roller bearing 21 arranged on the frame 1, and the cylindrical roller bearing 21 is rotatably connected to a shaft 22. The center of the disk gear 311 is fixedly connected to the top of the shaft 22. The center of the disk gear 311 and the top of the shaft 22 can be fixed by means of socket connection. An unloading cone 312 is arranged at the upper part of the receiving disk 31, and the diameter of the unloading cone 312 gradually increases from top to bottom. The hollow cylinder 32 is arranged on the frame 1, and the bottom of the hollow cylinder 32 contacts the top wall of the receiving disk 31. The unloading cone 312 is located inside the hollow cylinder 32. An outlet 321 is arranged on the hollow cylinder 32. In this embodiment, due to the reason of the factory building site, a disk feeder with a 1200-mm receiving disk 31 is selected. Among them, because the distance between the receiving height of the next working station and the factory building site is 1140 mm, the distance between the horizontal plane where the outlet 321 is located in this embodiment and the factory building site should be set to be greater than 1140 mm. The unloading cone 312 is designed according to the natural angle of repose of large-particle materials (selenium ingots).

[0028] The receiving disk 31 realizes rotation through the cooperation of the disk gear 311 and the shaft 22. Specifically, the shaft 22 rotates relative to the cylindrical roller bearing 21, thereby driving the disk gear 311 and the receiving disk 31 to rotate. Generally, a ton bag is lifted above the large-particle disk feeder, and the large-particle materials (selenium ingots, whose size is between 0 mm and 250 mm) in the ton bag fall into the area between the receiving disk 31, the hollow cylinder 32, and the unloading cone 312. The setting of the unloading cone 312 enables the large-particle materials to fall along the unloading cone 312. After the receiving disk 31 rotates, it will drive the large-particle materials in the area to rotate, and the large-particle materials are displaced. When the large-particle materials move to the outlet 321, the large-particle materials fall from the outlet 321 to the next working station.

[0029] For the large-particle disk feeder of this embodiment, first, the cylindrical roller bearing 21 is used to replace the two-end self-aligning roller bearings on the traditional disk feeder. And due to the limited factory building site, belt, screw and other conveyors cannot be used. The setting of the cylindrical roller bearing 21 greatly shortens the height of the transmission mechanism 2. It occupies a small space, has a simple transmission structure, and is convenient for maintenance. Second, it can smoothly convey large-particle materials.

[0030] As an implementable manner, a sealing plate 33 is fixedly connected between the bottom of the hollow cylinder 32 and the material receiving disc 31. The upper outer periphery of the material receiving disc 31 has a stepped structure. The bottom of the hollow cylinder 32 contacts the upper surface of the stepped structure on the material receiving disc 31. One end of the sealing plate 33 is fixedly connected to the bottom of the hollow cylinder 32, and the other end of the sealing plate 33 contacts the lower surface of the stepped structure on the material receiving disc 31. The sealing plate 33 is a rubber sealing plate 33, which can prevent powder and broken selenium ingots from leaking between the bottom of the hollow cylinder 32 and the material receiving disc 31 and polluting the factory site.

[0031] As an implementable manner, a baffle plate 322 is inclinedly arranged on the inner wall of the hollow cylinder 32. The baffle plate 322 is designed according to the natural repose angle of large-particle materials (selenium ingots). The baffle plate 322 is located on the side of the discharge port 321. A reinforcing rib 323 is fixedly connected between the baffle plate 322 and the hollow cylinder 32. Specifically, one end of the reinforcing rib 323 is fixedly connected to the lower end surface of the baffle plate 322, and the other end is fixedly connected to the inner wall of the hollow cylinder 32. The reinforcing rib 323 stably connects the baffle plate 322 and the hollow cylinder 32. The baffle plate 322 can block large-particle materials, further facilitating the large-particle materials to fall from the discharge port 321.

[0032] As an implementable manner, a feeding hopper 324 is inclinedly arranged on the outer wall of the hollow cylinder 32. The feeding hopper 324 is located below the discharge port 321. After the large-particle materials fall from the discharge port 321 onto the feeding hopper 324, they enter the next working station.

[0033] As an implementable manner, a plurality of scraping blades 34 are uniformly arranged at the top of the feeding cone 312. The plurality of scraping blades 34 are arranged along the circumferential direction of the feeding cone 312. The function of the scraping blades 34 is to scrape the outer packaging bag of the ton bag. The large-particle disc feeder in this embodiment can be used in conjunction with an electric hoist. The electric hoist replaces manual feeding and automatically lifts the ton bag. The height of the horizontal plane where the top of the feeding cone 312 is located in this embodiment is lower than the height of the horizontal plane where the hollow cylinder 32 is located. When the ton bag is hoisted above the scraping blades 34 (i.e., the ton bag is inside the hollow cylinder 32), since the scraping blades 34 rotate with the feeding cone 312 and the material receiving disc 31, the scraping blades 34 can scrape the outer packaging bag of the ton bag. At this time, the large-particle materials (selenium ingots) in the ton bag fall from the ton bag into the area between the material receiving disc 31, the hollow cylinder 32 and the feeding cone 312, replacing manual feeding into the particle disc feeder, and the particle disc feeder realizes automatic feeding of large-particle materials.

[0034] As an implementable mode, it further includes a driving mechanism 4. The driving mechanism 4 includes a motor 41 and a speed reducer 42 arranged on the frame 1. The output shaft of the motor 41 is in transmission connection with the input end 421 of the speed reducer 42, and the output end 422 of the speed reducer 42 is in transmission connection with the disk gear 311. Among them, the motor 41 is a variable-frequency motor (frequency range: 0HZ to 50HZ), and the speed reducer 42 is a worm gear speed reducer 42. When the motor 41 starts, it drives the speed reducer 42 to operate. After the speed reducer 42 operates, it drives the disk gear 311 to rotate. Specifically, the gear on the output end 422 of the speed reducer 42 meshes with the disk gear 311, and finally the disk gear 311 rotates. The motor 41 can adjust the conveying speed of large granular materials to meet the subsequent production rhythm.

[0035] As an implementable mode, a plurality of upper support columns 11 are evenly arranged on the upper part of the frame 1. A plurality of L-shaped fixing blocks 35 are evenly arranged on the outer wall of the hollow cylinder 32. Each L-shaped fixing block 35 is fixedly connected to the upper support column 11. The L-shaped fixing block 35 and the upper support column 11 are provided with holes, and the L-shaped fixing block 35 and the upper support column 11 are fixedly connected by the holes and bolt nuts on them. Among them, the number of the upper support columns 11 and the L-shaped fixing blocks 35 in this embodiment is set to four groups. Further, the upper support column 11 is fixedly connected to the upper part of the frame 1 by bolt nuts.

[0036] As an implementable mode, the transmission mechanism 2 further includes a bearing seat 23 arranged at the lower part of the frame 1. The bottom of the cylindrical roller bearing 21 is arranged in the bearing seat 23. The cylindrical roller bearing 21 is sleeved on the bearing seat 23, and the bearing seat 23 supports and fixes the cylindrical roller shaft 22. Further, the bearing seat 23 is fixedly connected to the lower part of the frame 1 by bolt nuts.

[0037] As an implementable mode, a plurality of lower support columns 12 are evenly arranged at the lower part of the frame 1. Further, the lower support columns 12 are fixedly connected to the lower part of the frame 1 by bolt nuts. Each lower support column 12 is evenly provided with support feet 13, and the support feet 13 support and fix the whole large granular disk feeder. The arrangement of the lower support columns 12 raises the overall height of the large granular disk feeder to meet the use requirements.

[0038] Conveying process of the large-particle disk feeder: The motor 41 starts, driving the reducer 42 to operate. After the reducer 42 operates, it drives the disk gear 311 and the receiving disk 31 to rotate. When the ton bag is lifted above the scraper 34, due to the rotation of the scraper 34, the outer packaging bag of the ton bag can be scraped and broken. At this time, the large-particle materials in the ton bag fall from the ton bag to the area between the receiving disk 31, the hollow cylinder 32 and the feeding cone 312. The receiving disk 31 continues to rotate, driving the large-particle materials in the area to rotate. The large-particle materials are displaced. When the large-particle materials move to the discharge port 321, the large-particle materials fall from the discharge port 321 onto the feeding hopper 324 and then enter the next working station.

For those skilled in the art of this technology, of course, other implementation manners can be easily made by means of replacement or change according to the technical content disclosed in this specification.
