Abstract
Description
Technical Field
[0001] This utility model relates to the field of material conveying technology, and in particular to a novel anti-jamming three-way hopper. Background Technology
[0002] In conventional coal conveying systems at power plants, belt conveyors are used in conjunction with hoppers. In the design of transfer hoppers, three-way hoppers are inevitably used. Three-way hoppers can make the most efficient use of the site and allow the two belt conveyor systems to be switched and allocated as needed.
[0003] However, the biggest problem with conventional three-way hoppers is that during operation, material is easily splashed onto the shell by the flap in the hopper. Also, because the flap and the shell are in contact, material gets stuck between the flap and the shell, making it impossible for the flap to rotate and adjust the feeding direction, which leads to equipment shutdown. Utility Model Content
[0004] The technical problem to be solved by this utility model is to develop a new type of anti-jamming three-way hopper that is not prone to jamming during use.
[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:
[0006] A novel anti-jamming three-way hopper includes a shell, a tipping bucket, and a partition. The shell has an inlet at the top and outlets on both sides at the bottom. An inner liner is provided at the top opening of the shell. A rotating shaft groove is opened in the middle of the two openings at the bottom of the shell. The tipping bucket is rotatably mounted in the shell. The rotating shaft at the bottom of the tipping bucket is rotatably mounted in the rotating shaft groove and extends out of the rotating shaft groove. A partition is vertically mounted in the middle of the tipping bucket. The length of the partition is such that the tipping bucket can abut against one side of the inner liner when rotating. When it abuts against one side of the inner liner, the opposite side of the inner liner extends into the tipping bucket. Discharge holes are opened on the two side walls of the tipping bucket opposite to the partition.
[0007] The beneficial effects of this utility model are as follows: When material is discharged from the lower right outlet, the rotating shaft is rotated counterclockwise to make the tipping bucket rotate until the top of the partition plate abuts against the left side of the inner lining. When the material falls from the inlet, it first hits the partition plate, then flows out of the tipping bucket from the discharge hole on the right side of the partition plate, and finally flows out from the outlet at the lower right of the shell. When material is discharged from the outlet at the lower left of the shell, the rotating shaft is rotated clockwise to make the tipping bucket rotate until the top of the partition plate abuts against the right side of the inner lining. When the material falls from the inlet, it first hits the partition plate, then flows out of the tipping bucket from the discharge hole on the left side of the partition plate, and finally flows out from the outlet at the lower left of the shell. The tipping plate in the prior art is replaced with a tipping bucket with a partition plate, and an inner lining is provided so that the partition plate rests against the inner lining, replacing the abutment between the tipping plate and the shell in the prior art. The material is directly introduced into the tipping bucket from the inner lining without splashing onto the shell, thereby effectively avoiding material jamming and the inability of the three-way hopper to adjust the feeding direction.
[0008] On the basis of the above technical solution, the present invention can also be improved as follows.
[0009] Furthermore, angle steel is provided on the outer edges of the two side walls opposite to the bucket and the partition.
[0010] Furthermore, the partition has a double-layer structure, and the plates at both ends are radiating outwards and connecting to the tipping bucket.
[0011] Furthermore, each layer of the partition is fixedly spliced together by multiple backing plates.
[0012] Furthermore, the side panels of the lining are angled and move closer to the center.
[0013] Furthermore, the included angle between the two side plates opposite the lining and the partition is greater than 25° and less than 35°. Attached Figure Description

[0022] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.
[0023] like Figures 1-6 As shown in Embodiment 1 of this utility model, a novel anti-jamming three-way hopper comprises a shell 1, a tipping bucket 2, and a partition 3. The shell 1 has an inlet 13 at the top and outlets 14 on both sides at the bottom. An inner liner 11 is provided at the top opening of the shell 1. A rotating shaft groove 12 is provided in the middle of the two openings at the bottom of the shell 1. The tipping bucket 2 is rotatably disposed in the shell 1. The rotating shaft 21 at the bottom of the tipping bucket 2 is rotatably disposed in the rotating shaft groove 12 and extends out of the rotating shaft groove 12. A partition 3 is vertically disposed in the middle of the tipping bucket 2. The length of the partition 3 is such that when the tipping bucket 2 rotates, it can abut against one side of the inner liner 11. When the partition 3 abuts against one side of the inner liner 11, the opposite side of the inner liner 11 extends into the tipping bucket 2. Discharge holes 22 are provided on the two side walls of the tipping bucket 2 opposite to the partition 3.
[0024] When material is discharged from the lower right outlet 14, the shaft 21 is rotated counterclockwise to rotate the tipping bucket 2 until the top of the partition 3 abuts against the left side of the liner 11. When the material falls from the inlet 13, it first hits the partition 3, then flows out of the tipping bucket 2 from the discharge hole 22 on the right side of the partition 3, and finally flows out from the lower right outlet 14 of the shell 1. When material is discharged from the lower left outlet 14 of the shell 1, the shaft 21 is rotated clockwise to rotate the tipping bucket 2 until the top of the partition 3 abuts against the right side of the liner 11. When the material outlet 13 falls, it first hits the partition plate 3, and then flows out of the tipping bucket 2 from the discharge hole 22 on the left side of the partition plate 3. The material flows out from the discharge port 14 at the lower left of the shell 1. The existing tipping plate is replaced with a tipping bucket 2 with a partition plate 3, and an inner liner 11 is provided so that the partition plate rests against the inner liner 11, replacing the abutment between the tipping plate and the shell 1 in the existing technology. The material is directly introduced into the tipping bucket from the inner liner 11 and will not splash onto the shell 1, thereby effectively avoiding material jamming and the inability of the three-way hopper to adjust the feeding direction.
[0025] Embodiment 2 of this utility model discloses a novel anti-jamming three-way hopper. Based on Embodiment 1, angle steel 23 is provided on the outer edges of the two side walls opposite to the partition plate 3 of the tipping bucket 2. The angle steel 23 can prevent the tipping bucket 2 from being worn and deformed by repeated collisions, thus ensuring the service life of the tipping bucket 2.
[0026] This utility model, in its third embodiment, presents a novel anti-jamming three-way hopper. Based on embodiment 1, the partition 3 has a double-layer structure, with the plates at both ends diverging and connecting to the tipping bucket 2. This structure offers high strength and good impact resistance, preventing the partition 3 from deforming under material pressure. Furthermore, it guides the material from both sides towards the center, facilitating material flow out from 22.
[0027] Embodiment 4 of this utility model presents a novel anti-jamming three-way hopper. Based on Embodiment 3, each layer of the partition 3 is fixedly spliced together by multiple lining plates 31. This facilitates later maintenance; during maintenance, only some damaged lining plates 31 need to be replaced, thus improving economic efficiency.
[0028] Embodiment 5 of this utility model presents a novel anti-jamming three-way hopper. Based on Embodiment 1, the side plates of the inner lining 11 are inclined and converge towards the center. This allows falling materials to be gathered towards the middle.
[0029] This utility model, in its embodiment 6, presents a novel anti-jamming three-way hopper. Based on any one of embodiments 1 to 5, the included angle between the two side plates opposite the inner lining 11 and the partition 3 (i.e., the included angle generated by the extension of the two side plates) is greater than 25° and less than 35°. While ensuring efficient material feeding, the tipping bucket 2 has a short stroke, resulting in less work done by the external motor connected to the rotating shaft 21, thus saving energy.
[0030] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
