Description

Technical Field

[0001] This utility model relates to the field of coal hopper modification technology, and in particular to a modification device for dividing coal hoppers into compartments. Background Technology

[0002] In power plants, coal hoppers are crucial equipment for fuel storage and transportation. With rising coal prices, existing power plants are using coal of varying qualities to reduce costs. Traditional coal hoppers, typically single-compartment structures, cannot simultaneously store different types or qualities of coal, limiting fuel allocation flexibility. Furthermore, a single compartment malfunctioning or requiring maintenance can lead to coal supply interruptions, impacting system reliability. Currently, most coal hopper compartments use a single steel plate as a divider, but this method has significant drawbacks. Strict control of coal quantity on both sides during operation poses safety risks and wastes considerable manpower. Therefore, a solution is urgently needed.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0022] Example

[0023] See Figure 1-4 As shown: This utility model provides a modification device for dividing a coal hopper into four compartments, including: a coal hopper 10, a first dividing support 20, and a second dividing part. The lower end of the coal hopper 10 is provided with four conical sections 11, and the bottom end of each conical section 11 is a discharge port of the coal hopper 10. The first dividing support 20 and the second dividing part are both disposed within the coal hopper 10, dividing the working chamber of the coal hopper 10 into four compartments, and the bottom ends of the four compartments are respectively connected to the four conical sections 11.

[0024] In practical use, by opening the gate at the discharge port of the conical section 11, the materials in the hopper can be unloaded separately. This further optimizes the internal space of the coal hopper 10, improves the utilization rate of the coal hopper 10, enables it to meet more production batching needs, and provides better support through the cross-shaped partition formed inside the coal hopper by the first partition support and the second partition, thus improving the safety of the equipment during use.

[0025] The first partition support 20 is arranged along the X-axis or Y-axis of the coal hopper 10, and both ends of the first partition support 20 are fixedly connected to the inner walls of both sides of the coal hopper 10. The second partition is arranged on both sides of the first partition support 20, and one end of the second partition is perpendicularly connected to the first partition support 20, and the other end of the second partition is connected to the inner wall of the coal hopper 10.

[0026] In practical applications, the first partition support 20 includes a support beam 21 and a steel plate 22. The two ends of the support beam 21 are connected to the inner walls on both sides of the coal hopper 10. The steel plate 22 is disposed on both sides of the support beam 21 and connected to the support beam 21. The bottom end of the steel plate 22 extends into the conical section 11 and is connected to the conical section side plate 111 of the conical section 11.

[0027] With this setup, the compressive force of the material in the hopper on the steel plate 22 is transmitted to the coal hopper 10 through the support beam 21, and then from the coal hopper 10 to the external support structure, thereby improving the safety of the entire device during use.

[0028] In practical applications, there are multiple support beams 21, distributed along the vertical direction of the coal hopper 10. The distribution density of the support beams 21 at the lower end of the coal hopper 10 is greater than that at the upper end. This arrangement addresses the situation where the lower end of the coal hopper 10 experiences greater compressive force due to the pressure from the material above. Therefore, by increasing the distribution density of the support beams 21, the lower part of the first partition support section 20 can withstand more material compressive force, thereby improving the safety of the device.

[0029] It also includes upper inclined plates 23; there are two upper inclined plates 23, located on both sides of the support beam 21, with one end of the two upper inclined plates 23 connected to each other, and the other end connected to the top of the steel plates 22 on both sides of the support beam 21, forming a conical guide slope on both sides of the top of the support beam 21. This arrangement not only encloses the support beam 21 within the entire first partition support section 20, but also forms a sloping inlet at the top of the hopper, facilitating rapid feeding.

[0030] It also includes a connecting plate 24; the connecting plate 24 is set at the connection between the steel plate 22 and the conical side plate 111, one side of the connecting plate 24 is attached to the surface of the conical side plate 111, and the other side is welded to the bottom end of the steel plate 22. By setting the connecting plate 24, the connecting plate 24 becomes a transition plate at the connection point between the steel plate 22 and the conical side plate 111, which not only provides better support for the bottom end of the steel plate 22 and increases the area of ​​the connection point, but also prevents the steel plate 22 from deforming due to the extrusion pressure of the material at the bottom of the hopper, making the connection between the steel plate 22 and the conical side plate 111 more stable and improving the stability of the device.

[0031] The second partition includes a first steel plate 31 and a second steel plate 32; one end of the first steel plate 31 and the second steel plate 32 are located on both sides of the support beam 21 and are perpendicularly connected to the steel plates 22 on both sides of the support beam 21, and the other end of the first steel plate 31 and the second steel plate 32 are connected to the inner walls on both sides of the coal hopper 10. The first steel plate 31, the second steel plate 32 and the steel plate 22 divide the working chamber inside the coal hopper 10 into four silos of the same volume.

[0032] By setting the second partition as two small steel plates, not only is the need for further division of the internal space of the coal hopper 10 met, but also the structural safety requirements are met because the main stress is borne by the support beam 21 of the first partition support. Compared with the traditional method of using only steel beams or only steel plates for partitioning, this device not only provides better safety and stability, but also reduces weight and cost while ensuring the need for further division of the internal space of the hopper 10, and improves the actual use effect.

[0033] In practical applications, when the internal space of the coal hopper 10 is large, sub-support beams for reinforcement are installed at the first steel plate 31 and the second steel plate 32 to improve the stability of the separated silo. The number of sub-support beams is twice the number of support beams 21. The sub-support beams are distributed on both sides of the support beams 21, and their elevation is at the same level as the support beams 21. They are arranged parallel to the first steel plate 31 and the second steel plate 32, with one end connected to the inner wall of the coal hopper 10 and the other end perpendicularly connected to the middle of the support beam 21. There are two first steel plates 31 and two second steel plates 32. The two first steel plates 31 are respectively set on both sides of the sub-support beam and are fitted and connected to the support beam. The two second steel plates 32 are respectively set on both sides of the sub-support beam and are fitted and connected to the sub-support beam.

[0034] With this configuration, when there is a large amount of material in the silos separated by the first steel plate 31 and the second steel plate 32, or when the volumes are different, the first steel plate 31 and the second steel plate 32 can withstand the extrusion pressure exerted by the materials in the two adjacent silos due to the internal support of the sub-support beam, thus improving the stability of the entire device.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
