Technical Field

[0001] This utility model relates to the technical field of dust suppression devices, and in particular to a dust suppression device for a silo ring feeder. Background Technology

[0002] The silo ring feeder is a device used for quantitative coal feeding in the coal storage system of fuel silos in thermal power plants. It can feed materials evenly and quantitatively, and adjust the feed rate over a wide range. It is particularly suitable for use when several silos are connected, and can achieve the mixing of superior and inferior materials, thereby improving the comprehensive utilization rate of materials and enhancing the overall economic benefits of the power plant.

[0003] In practical applications, the existing silo-type ring feeder has a relatively complete structure and function, which can meet basic usage requirements. However, the following problems still exist:

[0004] Dust generated during the operation of the silo ring feeder conveying coal onto the coal conveyor belt covers the entire bottom of the silo and the first and second floors of the coal plow and unloading car. Dust sprays out from various doors and windows, causing poor environmental sanitation and affecting environmental protection. The high dust density in this area also poses a great safety hazard. Because of the high dust, inspection personnel cannot enter the equipment to inspect it after it is turned on, which affects the safe operation of the equipment.

[0005] Therefore, this utility model provides a dust suppression device for a silo ring feeder. Utility Model Content

[0027] 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 some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] like Figures 1-6 As shown, this embodiment provides a technical solution: a dust suppression device for a silo ring feeder, including a base plate 1 and a silo body 2. An annular guide rail 10 is fixedly connected to the top of the base plate 1. A guide wheel 3 is installed on the top of the annular guide rail 10. A transmission ring plate 4 is fixedly connected to the top of the guide wheel 3. A coal receiving plate 5 is fixedly connected to the top of the transmission ring plate 4. An annular plate 9 is fixedly connected to the inner surface of the coal receiving plate 5. The bottom of the silo body 2 is fixedly connected to the top of the base plate 1 via a connecting rod. The bottom of the silo body 2 is located above the coal receiving plate 5. A discharge port 8 is opened at the bottom of the silo body 2, and a discharge hole 11 is opened on one side of the silo body 2. A splash-proof dust suppression structure 6 is provided on the outer side of the coal receiving plate 5. The splash-proof dust suppression structure 6 includes a flat iron ring plate 61, the inner surface of which is fixedly connected to the outer side of the coal receiving plate 5. An auxiliary dust prevention structure 7 is provided on the inner surface of the annular plate 9. The auxiliary dust prevention structure 7 includes an annular plate 9. The rubber baffle 72 and the movable clamping plate 74 are arranged in a rectangular baffle 711. The rubber baffle 72 is located between the movable clamping plate 74 and the annular plate 9. By setting the anti-splash and dust suppression structure 6, the anti-splash baffle 64 can be installed with the help of the annular locking block 63 and the annular locking groove 62. This can help prevent splashing and dust suppression in the gap between the silo body 2 and the coal receiving plate 5, thus avoiding pollution of the working environment caused by the splashing of slag and dust. At the same time, the rectangular baffle 611 can help protect the discharge hole 11, preventing slag and dust from splashing out of the discharge hole 11. By setting the auxiliary dust prevention structure 7, the rubber baffle 72 can be fixed with the help of the movable clamping plate 74 and the second threaded locking rod 76, in conjunction with the third screw hole 71, the fourth screw hole 73 and the fifth screw hole 75. This can protect the gap between the annular plate 9 and the silo body 2, thus preventing the splashing of slag and dust.

[0029] Going further, such as Figure 3As shown: The top of the flat iron ring plate 61 is provided with an annular groove 62, and the inner wall of the annular groove 62 is fitted with an annular block 63. The top of the annular block 63 is fixedly connected with a splash guard 64, and the bottom of the annular block 63 is fixedly connected with a threaded rod 65. The bottom of the annular groove 62 is provided with a round insertion hole 66, and the bottom end of the threaded rod 65 is threadedly connected with a fixing nut 67. Under the action of the annular block 63 and the annular groove 62, the splash guard 64 can be disassembled and assembled, thereby sealing and protecting the gap between the coal receiving plate 5 and the silo body 2, preventing dust and debris from splashing out from the gap. At the same time, under the action of the threaded rod 65 and the fixing nut 67, the annular block 63 can be limited and fixed in conjunction with the round insertion hole 66.

[0030] The above solution also has the problem that debris and dust will splash out at discharge port 11, thus affecting the working environment. Figure 4 As shown: In this scheme, a rectangular auxiliary plate 68 is fixedly connected to the silo body 2. A rectangular slot 69 is provided on the inner wall of the rectangular auxiliary plate 68. A rectangular insert 610 is inserted into the inner wall of the rectangular slot 69. A rectangular baffle 611 is fixedly connected to the bottom of the rectangular insert 610. A first screw hole 612 is provided on one side of the rectangular auxiliary plate 68. A second screw hole 613 is provided on one side of the rectangular insert 610. A first threaded clamp 614 is threadedly connected to the inner wall of the first screw hole 612 and the second screw hole 613. Under the action of the rectangular insert 610 and the rectangular slot 69, the rectangular baffle 611 can be clamped and fixed. At the same time, under the action of the first screw hole 612 and the second screw hole 613, the rectangular insert 610 can be fixedly installed in conjunction with the first threaded clamp 614, thereby sealing the discharge hole 11 and preventing dust and debris from splashing out.

[0031] The above solution also suffers from the problem of unstable fixing of the rectangular insert 610 and the rectangular slot 69 by friction, such as... Figure 3 and Figure 5 As shown, the inner wall of the rubber baffle 72 has a fourth screw hole 73, the inner wall of the annular plate 9 has a third screw hole 71, and the inner wall of the movable clamping plate 74 has a fifth screw hole 75. The inner walls of the third screw hole 71, the fourth screw hole 73, and the fifth screw hole 75 are threadedly connected to a second threaded clamping rod 76. Under the action of the movable clamping plate 74, the second threaded clamping rod 76 can assist in fixing the rubber baffle 72, thereby sealing and preventing splashing between the annular plate 9 and the silo body 2.

[0032] Working principle:

[0033] like Figure 1-6 As shown:

[0034] In use: The annular locking block 63 is engaged with the annular locking groove 62, and the threaded rod 65 can be inserted into the inner wall of the round insertion hole 66. The fixing nut 67 is then fixed to the threaded rod 65, which allows the splash guard 64 to provide auxiliary sealing to the silo body 2 and the coal receiving plate 5.

[0035] At this time, the rectangular insert 610 is engaged with the rectangular slot 69, and then the first threaded rod 614 is fixed with the first screw hole 612 and the second screw hole 613, so that the rectangular baffle 611 can assist in blocking the discharge hole 11.

[0036] At this time, the rubber baffle 72 is placed between the movable clamping plate 74 and the annular plate 9, which can then fix the second threaded clamping rod 76 to the third screw hole 71, the fourth screw hole 73 and the fifth screw hole 75, thereby fixing the rubber baffle 72 and providing auxiliary protection for the gap between the annular plate 9 and the silo body 2.

[0037] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
