Description

Technical Field

[0001] The utility model relates to the field of electromagnetic vibrating feeders, in particular to an improved electromagnetic vibrating feeder. Background Art

[0002] The electromagnetic vibrating feeder plays a key role in the CDQ coke discharge system of a coking plant. Its main function is to quantitatively discharge the coke after the CDQ furnace is cooled and feed it into the rotary sealing valve. Traditional electromagnetic vibrating feeders have many drawbacks:

[0003] First, the trough of a conventional electromagnetic vibrating feeder is a square structure with right-angled bottoms on both sides. When processing chemical coke with smaller particle size and coke with a high coke powder content, the powder easily accumulates in the corners and is not easy to fall off, resulting in a small processing capacity of the vibrating feeder, which may even be difficult to meet production needs.

[0004] Secondly, the trough of the electromagnetic vibrating feeder contains not only coke but also carbon monoxide gas, so the inner wall of the trough needs to be wear-resistant and well-sealed. The conventional practice is to install a wear-resistant liner inside the trough and fix the liner and trough with bolts. However, bolting alone cannot ensure sealing and may cause carbon monoxide leakage. Therefore, it is necessary to apply sealant to the bolts on the outside of the trough to seal it. However, this method is inefficient and the appearance of the trough after applying the sealant is poor. If the sealant is not applied properly and leaks occur, the subsequent treatment is extremely troublesome.

[0005] Third, dozens of spring steel plates are installed inside the vibration source of the electromagnetic vibrating feeder. In order to ensure that each spring steel plate has sufficient deformation during operation, three pads are bonded to the surface of the spring steel plate. However, in the conventional bonding process, after the glue cures, a very thin layer of glue will remain between the pad and the spring steel plate, and the glue is very brittle. Pressing the spring steel plate during assembly will cause the glue to crack, resulting in the pad loosening and the spring steel plate unable to be compacted, which will ultimately affect the mechanical properties of the electromagnetic vibrating feeder.

[0006] Therefore, those skilled in the art provide an improved electromagnetic vibrating feeder to solve the problems raised in the above background technology. Summary of the Invention

[0007] In order to solve the above technical problems, the utility model provides an improved electromagnetic vibrating feeder, including a vibration source and a material trough. The vibration source is connected to one side of the material trough, the internal connection of the vibration source is provided with a spring steel plate, the upper end of the spring steel plate is connected with a pad, the internal connection of the material trough is provided with an arc lining plate, and the arc lining plate is connected to the material trough by a fixed structure.

[0008] Furthermore, the material trough is an arc-shaped structure.

[0009] Furthermore, the arc-shaped lining plate is made of heat-resistant and wear-resistant steel plate or high-chromium cast iron.

[0010] Furthermore, the fixing structure includes screws, copper washers, steel washers, and locking nuts. The threaded end of the screw passes through the arc-shaped lining and the material trough and extends to the outside of the material trough. The copper washers and steel washers are both sleeved on the outside of the threaded end of the screw, and the locking nut is threadedly sleeved on the outside of one end of the screw.

[0011] Furthermore, the copper pad and the steel pad are both connected to the outside of the trough.

[0012] Furthermore, a sealing member is provided on the outer side of the screw.

[0013] Furthermore, the sealing member is one of a sealant applied to the outside of the screw and a high-temperature resistant sealing gasket wrapped around the outside of the screw.

[0014] Furthermore, the other end of the screw is provided with a wear-resistant layer.

[0015] Furthermore, the spring steel plate and the backing plate are bonded with silicone.

[0016] The technical effects and advantages of the utility model are as follows: 1. The bottom of the trough is an arc-shaped structure, so powdered materials will not accumulate in the corners when passing through, which will affect the discharge volume; 2. The top of the trough adopts an arc-shaped structure, which reduces stress concentration during welding, increases the strength of the trough, and echoes the arc shape of the bottom, which is more beautiful; 3. Heat-resistant wear-resistant steel plates are installed inside the trough, which can not only ensure that the hardness of the steel plate surface meets the wear requirements in a high-temperature environment, but also reduce the number of seams and fastening bolts of the wear-resistant steel plates, reduce the resistance of the wear-resistant steel plate surface, and facilitate material discharge. In addition, the reduction in the number of bolts can reduce the risk of leakage and improve production efficiency. 4. The arc structure can increase the strength of the trough and reduce the weight of the equipment itself, which can not only reduce the manufacturing cost, but also reduce the load of the equipment on the steel structure frame; 5. A fixed structure is adopted to play a sealing role, and the sealant or high-temperature resistant sealing gasket sealed between the screws and the trough cavity plays a secondary sealing role to ensure the sealing effect; this fixed form has a simple structure, high installation efficiency, and good sealing performance, which can meet a pressure of not less than 20kPa; in addition, in order to avoid coke wearing the screws and causing the liner to fall off, a wear-resistant layer is welded on the tail of the screw; 6. The spring steel plate and the pad are bonded at the end face with silicone that has a certain flexibility after curing. After bonding, there is no filler between the pad and the spring steel plate, and the spring steel plate is completely fitted with the pad when pressed, and the pad will not fall off, which can well ensure the mechanical properties of the electromagnetic vibrating feeder.
