Description

Technical Field

[0001] The utility model relates to the technical field of coal feeding drums, in particular to a leakage-proof coal feeding drum for a two-stage gas producer. Background Technique

[0002] A gas producer refers to a reaction furnace used to produce gas, water gas and semi-water gas. During the operation of a two-stage gas producer, lump coal in the bunker enters the furnace by alternately combining and switching two groups of coal feeding drums. Each coal feeding drum valve switches 6-8 times per hour, and the drum runs relatively frequently.

[0003] During the working stroke of the coal feeding drum valve, when the inner drum rotates, it rotates with a very small gap between the outer wall of the coal drum. Fine coal particles in the lump coal will enter the gap. During the rotation of the drum valve, the gap will become larger due to friction, which will exacerbate the problem of gas leakage of the coal feeding drum valve and affect the service life of the coal feeding drum. For this reason, a leakage-proof coal feeding drum for a two-stage gas producer is proposed. Content of the Utility Model

The extending length of the baffle is equal to the distance between the outer wall of the inner cylinder and the inner wall of the housing.

[0006] As a further preferred solution of this technical solution, the oil inlet mechanism is composed of four oil inlet components with the same structure. The four oil inlet components are symmetrically distributed in pairs on both sides of the housing.

[0007] As a further preference of this technical solution, the oil inlet assembly is composed of an oil inlet hole, a first-stage pipeline, a second-stage pipeline, a third-stage pipeline and an oil passage. The oil passage is axially opened on the inner wall of the housing. There are three oil inlet holes extending to the oil passage on the outer wall of the housing. One end of the first-stage pipeline is connected to an oil source, and the other end of the first-stage pipeline is connected to two second-stage pipelines. The other end of one second-stage pipeline is connected to one oil inlet hole, and the other end of the other second-stage pipeline is connected to two third-stage pipelines.

[0012] The utility model provides an anti-leakage coal feeding roller for a two-stage gas producer, which has the following

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0023] The present utility model provides a technical solution: As Figures 1 to 6 shown, in this embodiment, a leakage-proof coal-feeding roller for a two-stage gas generator includes an outer shell 1. The upper and lower ends of the outer shell 1 are respectively provided with a feeding end 2 and a discharging end 3. An oil inlet mechanism is provided on the side wall of the outer shell 1. Fixed side plates 8 are respectively fixedly connected to both ends of the outer shell 1. An inner cylinder 6 is arranged inside the outer shell 1. The inner cylinder 6 and the outer shell 1 are on the same axis. Both ends of the inner cylinder 6 are respectively rotatably connected to the side walls of the two fixed side plates 8. A material port 10 is opened on the side wall of the inner cylinder 6. The size of the material port 10 is adapted to the opening size of the feeding end 2. A baffle 11 is arranged on the inner cylinder 6 at the position of the material port 10. The baffle 11 is of a frame structure and is adapted to the material port 10. Fixed holes 12 penetrating through the baffle 11 are opened on the four inner walls of the baffle 11. Threaded holes 13 are opened on the inner wall of the material port 10 at the extending positions of the fixed holes 12. The upper surface of the baffle 11 extends above the outer wall of the inner cylinder 6. The protruding length of the baffle 11 is equal to the distance between the outer wall of the inner cylinder 6 and the inner wall of the outer shell 1.

[0024] Among them, the oil inlet mechanism is composed of four oil inlet components with the same structure. The four oil inlet components are symmetrically distributed in pairs on both sides of the outer shell 1.

[0025] Among them, the oil inlet assembly consists of an oil inlet hole 4, a primary pipeline 14, a secondary pipeline 15, a tertiary pipeline 16, and an oil passage 18. The oil passage 18 is axially provided on the inner wall of the housing 1. Three oil inlet holes 4 extending to the oil passage 18 are provided on the outer wall of the housing 1. One end of the primary pipeline 14 is connected to an oil source, and the other end of the primary pipeline 14 is connected to two secondary pipelines 15. The other end of one secondary pipeline 15 is connected to one oil inlet hole 4, and the other end of the other secondary pipeline 15 is connected to two tertiary pipelines 16. The other ends of the two tertiary pipelines 16 are respectively connected to the other two oil inlet holes 4.

[0026] The lubricating oil is introduced into the oil inlet passage 18 through the primary pipeline 14, the secondary pipeline 15, and the tertiary pipeline 16. As the inner cylinder 6 rotates, the outer wall of the inner cylinder 6 will gradually come into contact with the oil passage 18, so that the lubricating oil in the oil passage 18 is evenly smeared on the outer wall of the inner cylinder 6, making the rotation of the inner cylinder 6 smoother.

[0027] Among them, additional passages 19 are respectively provided on the front and rear sides of the inner wall of the housing 1. Two additional holes 5 extending to the outer wall of the housing 1 are provided on the additional passage 19. One additional hole 5 is connected to one secondary pipeline 15 through an additional pipeline 17, and the other additional hole 5 is connected to one tertiary pipeline 16 through another additional pipeline 17.

[0028] With such a setting, the number of oil passages can be increased, so that the lubricating oil between the inner cylinder 6 and the housing 1 is added more evenly, and the smearing effect of the lubricating oil is better.

[0029] Among them, the upper surface of the baffle 11 is an arc surface, and the radius of the arc surface is equal to the radius of the inner wall of the housing 1.

[0030] With such a setting, it can be ensured that the upper surface of the baffle 11 slides and fits with the inner wall of the housing 1.

[0031] Among them, the upper surface of the baffle 11 and the inner wall of the housing 1 are both polished.

[0032] With such a setting, the friction between the baffle 11 and the inner wall of the housing 1 can be reduced.

[0033] Among them, a sealing gasket 7 is provided between the fixed side plate 8 and the housing 1, and fluororubber gaskets 9 are provided at the upper end of the feeding end 2 and the bottom of the discharging end 3.

[0034] The sealing gasket 7 can improve the sealing between the fixed side plate 8 and the housing 1, avoiding leakage of the lubricating oil. The fluororubber gasket 9 can improve the sealing at the connection positions between the upper and lower ends of this equipment and other equipment.

[0035] The present utility model provides a leakage-proof coal feeding roller for a two-stage gas generator, and the specific working principle is as follows:

[0036] During use, by arranging a baffle 11 in the material inlet 10 of the inner cylinder 6, making the upper surface of the baffle 11 extend out of the material inlet 10, and making the extending length of the baffle 11 equal to the distance between the outer wall of the inner cylinder 6 and the inner wall of the outer shell 1, the gap between the inner cylinder 6 and the outer shell 1 can be separated from the interior of the inner cylinder 6, avoiding the problem that fine coal particles enter between the inner cylinder 6 and the outer shell 1 during the rotation of the inner cylinder 6, resulting in an increase in friction when the inner cylinder 6 rotates. The upper surface of the baffle 11 and the inner wall of the outer shell 1 are both polished to reduce the friction between the baffle 11 and the inner wall of the outer shell 1. Through the arranged oil inlet mechanism, lubricating oil can be introduced into the oil inlet channel 18 through the primary pipeline 14, the secondary pipeline 15 and the tertiary pipeline 16. As the inner cylinder 6 rotates, the outer wall of the inner cylinder 6 will gradually come into contact with the oil channel 18, so that the lubricating oil in the oil channel 18 is evenly smeared on the outer wall of the inner cylinder 6, and further makes the rotation of the inner cylinder 6 smoother. The arranged additional channel 19 and additional hole 5 are used to increase the number of oil channels, making the addition of lubricating oil between the inner cylinder 6 and the outer shell 1 more uniform and the smearing effect of the lubricating oil better.

[0037] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
