Description

Technical Field

[0001] The utility model relates to the technical field of coke oven coal blending equipment, in particular to a double-discharging-port disc feeder. Background Art

[0002] When the coke oven in the coking industry is coking with coal, it is necessary to first determine the proportion of coking coal of different grades. The disc feeder is one of the most important equipment in the automatic coal blending process. The disc feeder is a mechanical equipment used for the supply of powder and granular materials. It is usually used to evenly and continuously supply granular materials to production lines or other processing equipment. The disc feeder sleeve generally has two types: snail type or straight barrel type. The snail type sleeve adopts gate discharge, which has uniform and accurate discharge, and is suitable for solvent, reverse ore powder and other ingredients. The straight barrel sleeve adopts scraper discharge, and the blocking phenomenon is lighter than the snail type sleeve, but the discharge amount fluctuates greatly. When the amount of concentrate powder and active powder ore is large, it is advisable to use a straight barrel sleeve with a movable scraper. On the contrary, when the amount of flux or fuel is small, it is advisable to use a snail type sleeve with a gate.

[0003] The existing straight-cylinder disc feeder has only one discharge port. One disc feeder can only discharge materials in one silo and in one direction or at a single discharge point. However, a double discharge line is usually designed under the silo, one for use and one for backup, to avoid the problem of equipment failure affecting production. If you want to discharge materials in multiple directions or multiple discharge points at the same time, you need multiple disc feeders to work at the same time. Multiple disc feeders working at the same time not only occupy a large area, but also require more squares, and require more equipment investment, and have high operating costs. In addition, the existing straight-cylinder disc feeder only has multiple scraper blades evenly distributed along the radial direction of the disc at the bottom of the main shaft. When there is a lot of material, this design will have a large resistance to the single-layer scraper, which is prone to equipment jamming and scraper deformation, thereby affecting the discharge efficiency.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example 1

[0025] like Figure 1-3 As shown, a double-discharge-port disc feeder comprises a frame 1, a cylindrical frame 4, a power device 2 and a disc 3.

[0026] The cylindrical frame 4 is fixedly arranged above the frame 1 , and the frame 1 has four supporting legs. The power device 2 is installed between the four supporting legs of the frame 1 , and the disc 3 is fixedly arranged in the cylindrical frame 4 .

[0027] The cylindrical frame 4 is provided with two feeding troughs symmetrically arranged along the diameter of the disc 3, valves are provided at the bottom of the two feeding troughs, belt conveyors are provided at the bottom of the two feeding troughs, a rotating seat 8 is installed on the top of the cylindrical frame 4, and the power device 2 is connected to the rotating seat 8 through a transmission assembly. Specifically, the power device 2 is an electric motor, and the transmission assembly is a reduction box. The output shaft of the reduction box passes through the disc and is fixedly connected to the rotating seat 8, and a bearing is provided at the connection between the output shaft and the disc.

[0028] Preferably, Figure 4 As shown, the valve is a gate valve, which can be a pneumatic or electric and manual gate valve. Specifically, the valve is an electric gate valve, including a box 18, a gate 19 and an electro-hydraulic push rod 16. The box 18 is arranged at the bottom of the feeding trough, and the electro-hydraulic push rods 16 are installed on both sides of the box 18. The top of the piston rod 17 of the electro-hydraulic push rod 16 is connected to one end of the gate 19. The box 18 is installed at the bottom of the feeding trough, and the electro-hydraulic push rod 16 drives the piston rod 17 to move, and the piston rod 17 drives the gate 19 to move. When the valve is opened, the electro-hydraulic push rod 16 drives the piston rod 17 to move to the left end, thereby driving the gate 19 to move to the left end, so that the gate 19 is no longer blocking the bottom of the feeding trough, so that the feeding trough can discharge materials; on the contrary, when the electro-hydraulic push rod 16 drives the piston rod 17 to move to the right, the valve is closed.

[0029] A further solution of the present invention is that: Figure 1 As shown, the two feed troughs include a first feed trough 5 and a second feed trough 11, the valves include a first valve 6 and a second valve 12, and the belt conveyors include a first belt conveyor 7 and a second belt conveyor 13. The first valve 6 is provided at the bottom of the discharge port of the first feed trough 5, and the second valve 12 is provided at the bottom of the discharge port of the second feed trough 11. Below the discharge port of the first feed trough 5 is the first belt conveyor 7; below the discharge port of the second feed trough 11 is the second belt conveyor 13.

[0030] like Figure 1 As shown, long scrapers 9 are evenly and vertically installed on the side of the rotating seat 8, and short scrapers 10 are evenly and vertically installed in the gaps between the long scrapers 9.

[0031] Specifically, four long scrapers 9 are provided, the four long scrapers 9 are perpendicular to each other and are evenly distributed circumferentially on the rotating seat 8, that is, cross distribution, and four short scrapers 10 are provided. The four short scrapers 10 are perpendicular to each other and are evenly distributed circumferentially on the rotating seat 8 in the gaps between the long scrapers 9. When the single-layer long scrapers 9 and the short scrapers 10 are staggered, the long scrapers 9 and the short scrapers 10 can be welded to the rotating seat 8, that is, one end of the long scraper 9 and the short scraper 10 are vertically welded to the outer wall of the rotating seat 8.

[0032] Example 2

[0033] This embodiment is based on the embodiment 1. In order to realize the double-layer staggered design of the long scraper 9 and the short scraper 10, a further solution is as follows: Figure 2 As shown, the long scraper 9 and the short scraper 10 can be raised and lowered along the rotating seat 8. Specifically, the four long scrapers 9 are welded and arranged on the first ring 15 in the form of a cross distribution of Example 1. The first ring 15 is slidably connected to the rotating seat 8. A plurality of through bolt holes are evenly arranged on the outer wall of the first ring 15 along the circumferential direction. Corresponding multi-layer bolt holes are arranged at a suitable height on the outer wall of the rotating seat 8, and are fixed after the bolts penetrate the corresponding bolt holes of the two layers; similarly, the four short scrapers 10 are welded and arranged on the second ring 14 in the form of a cross distribution. The second ring 14 is slidably connected to the rotating seat 8 and fixed by bolts. The design of this embodiment can realize both the same-layer staggered design of the long scraper 9 and the short scraper 10 and the double-layer staggered design of the long scraper 9 and the short scraper 10. When in the same layer, the second ring 14 is located above the first ring 15, but the long scraper 9 and the short scraper 10 are located at the same height, specifically, the short scraper 10 is designed to be lower than the second ring 14. In the case of double layers, the height of the short scraper 10 is raised by adjusting the height of the second ring 14 on the rotating seat 8, and then the second ring 14 is fixed at a proper height by bolts.

[0034] How it works:

[0035] The disc feeder of the utility model is arranged at the bottom of the silo, and double-row feeding lines are arranged on both sides of the bottom of the silo. After installation, the two feeding troughs of the disc feeder are just located above the two belt conveyors, that is, the first belt conveyor 7 corresponds to the first feeding trough 5, and the second belt conveyor 13 corresponds to the second feeding trough 11.

[0036] like Figure 1As shown, when the silo is feeding the first belt conveyor 7 on the left, the second discharge chute 11 is closed through the second valve 12, and the first discharge chute 5 is opened through the first valve 6. At this time, the motor is turned on, and the motor drives the rotating seat 8 to rotate, thereby driving the long scraper 9 and the short scraper 10 to rotate. When the discharge speed of the silo is low, the long scraper 9 and the short scraper 10 can be selected to work at the same layer. At this time, the short scraper 10 pushes the material in the center of the disc 3 to the outer layer, and the long scraper 9 pushes the material to the first discharge chute 5 and the second discharge chute 11. Since the second discharge chute 11 is in a closed state. Therefore, the material only falls from the first discharge chute 5 into the first belt conveyor 7 and enters the next step of the process; similarly, when feeding the second belt conveyor 13 on the right, the second valve 12 is opened and the first valve 6 is closed.

[0037] When the material discharge speed of the silo is high, due to the accumulation of material layers, the material generates a large resistance to the single-layer long scraper 9 and the short scraper 10, which will cause the deformation of the long scraper 9 and the jamming of the equipment. At this time, by adjusting the height of the short scraper 10, the long scraper 9 and the short scraper 10 are arranged in double layers in an alternating manner. The double-layer long scraper 9 and the short scraper 10 increase the contact area between the scraper and the material, effectively solving the problem of equipment jamming caused by thick material layers, thereby increasing the service life of the equipment.

[0038] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention.
