Description

Technical Field

[0001] The utility model relates to the technical field of coke oven coal blending equipment, in particular to a movable disc feeding device. Background Art

[0002] When the coke oven in the coking industry is blending coal for coking, 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 automated coal blending process. The disc feeder is a mechanical device 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 specific process of disc unloading is that the motor drives the disc through the coupling through the reducer. When the disc rotates, the material in the silo moves with the disc and moves to one side of the discharge port, and the material is discharged through the gate or scraper.

[0003] In actual coal blending plants, there are often several to dozens of silos, and each discharge port needs to be equipped with a disc feeder. However, in actual production, all silos are not supplied at the same time, resulting in the disc feeders under the non-working silos being in an idle state. A large amount of equipment investment not only increases production costs, but also increases the failure rate. In addition, multiple disc feeders are not conducive to maintenance and operation.

The frame 1 includes four supporting legs, that is, a driven walking component 7 is arranged at the bottom of each of the three supporting legs, and an active walking component 6 is arranged at the bottom of one of the supporting legs.

[0026] Specifically, the main structures of the active walking component 6 and the driven walking component 7 are the same. Figure 3 As shown, the active walking component 6 and the driven walking component 7 both include a mounting bracket 61, a walking wheel 63 and a rotating shaft 66. The top of the mounting bracket 61 is connected to the bottom of the supporting leg of the frame 1. Mounting side plates 62 are provided on both sides of the mounting bracket 61. A rotating shaft 66 is rotatably connected between the two mounting side plates 62. The walking wheel 63 is installed on the rotating shaft 66 through a key connection. Bearings 64 are provided at the connection between the two ends of the rotating shaft 66 and the mounting side plates 62, and a bearing cover plate 65 is provided at the outer end of the bearing 64.

[0027] The track assembly 9 includes a track 91 and a pressure plate 92. The track 91 is laid on the ground at the bottom of the silo. There are two tracks 91. The track 91 is an I-beam.

[0029] Example 2

[0030] This embodiment is based on the embodiment 1. In order to realize the automatic movement of the disc feeding device, the active walking component 6 is further provided with a positioning identification component 8.

[0032] One embodiment is that the sensor 82 is a proximity switch, which is electrically connected to the PLC control system 11 through a coding cable. A proximity switch is a position switch that can be operated without mechanical direct contact with a moving part. When an object approaches the sensing surface of the switch to the action distance, the switch can be actuated without mechanical contact or any pressure, thereby providing a control instruction to the PLC control system 11, and controlling the opening and closing of the travel motor 68 through the PLC control system 11. A proximity switch is a switch-type sensor (i.e., a contactless switch). It has the characteristics of a travel switch and a micro switch, and has sensing performance, reliable operation, stable performance, fast frequency response, long service life, strong anti-interference ability, and waterproof, shockproof, corrosion-resistant, etc. The products are inductive, capacitive, Hall, AC, and DC types. The detected object of the proximity switch is set at the bottom of each silo.

The photoelectric rotary encoder can convert the angular displacement, angular velocity and other mechanical quantities of the output shaft into corresponding electrical pulses and output them as digital quantities through photoelectric conversion. The encoder can be divided into photoelectric, magnetoelectric and contact brush types according to its working principle. The principles and circuits of the rotary encoder and the data acquisition card are prior art, and the selection and connection methods of the rotary encoder and the data acquisition card are well known to those skilled in the art, and will not be described in this patent.

[0034] Example 3

[0035] This embodiment is based on Embodiment 1 and Embodiment 2. Figure 2 As shown, in order to enable the disc feeding device to automatically clean the track 91 when moving, track cleaning components 10 are provided on both sides of the active traveling component 6 and the driven traveling component 7 along the length direction of the track 91.

[0036] Specifically, Figure 4 As shown, the track cleaning assembly 10 includes a support leg 101 and a brush 102. The support leg 101 is an L-shaped plate. The support leg 101 is installed on the front and rear sides of the mounting bracket 61 of the active walking assembly 6 and the driven walking assembly 7. The brush 102 is installed at the bottom of the support leg 101. The brush 102 is located above the track 91 and in contact with the track 91.

[0037] How it works:

[0038] After the coal blending plant is built, a track assembly 9 is laid on the ground below the bottom of multiple silos, and the movable disc feeder of the utility model is equipped according to the coal blending requirements, without the need to equip the bottom of each silo with a traditional disc feeder. Only a small number of disc feeders are needed to complete the work that can be completed by multiple traditional devices, saving a lot of costs and reducing maintenance and operating costs.

[0039] When the disc feeding device is working, the material in the silo enters the cylindrical frame from the discharge port through the short material receiving pipe, and the power device 2 drives the disc 3 to rotate. As the disc 3 rotates, the material flows out from the gate of the short material receiving pipe, and as the disc 3 rotates, it passes through the material guide scraper into the discharge chute 4, and is transported to the belt conveyor 5 through the discharge chute 4 to enter the next process.

[0040] The disc feeder moves back and forth on the track 91 laid on the ground. When it moves to the designated bin discharge port, the gate of the bin discharge port is opened through the interlocking signal, and the materials in the bin enter the disc feeder and are transported to the downstream belt conveyor 5. When other bins need to be unloaded, the gate of the bin discharge port is closed first through the interlocking signal, and then the running wheel 63 and the positioning identification device accurately move to the designated bin discharge port for unloading; and a track cleaning device is provided on the track 91, which automatically cleans the dust and slag on the track 91 when the disc feeder moves, so that the running wheel 63 can move smoothly on the track 91, reducing the failure rate of the equipment.
