Description
Technical Field
The utility model belongs to the technical field of the coal pulverizer, especially, relate to a separator guider for intermediate speed coal pulverizer.
Background
The medium-speed coal mill is the most important large-scale equipment in the coal-to-liquid and powder production system, the operation safety and the economical efficiency of the medium-speed coal mill are extremely important for the normal operation of the coal-to-liquid and powder production system, and the medium-speed coal mill can grind coal balls into fine pieces and effectively improve the coal-fired efficiency of a large-scale thermal power plant. The separator guide device is used as an important part in a medium-speed coal mill and has the function of enabling hot air to flow in a specific direction in a shell, however, the abrasion surface of the separator guide device is continuously impacted by pulverized coal particles driven by the hot air and is easy to grind through, particularly, the front surface of the separator guide device and the side surface close to the air outlet of an impeller device are more greatly impacted by the pulverized coal particles and are easy to grind through, once the abrasion surface of the separator guide device is ground through, the air flow movement in the coal mill is influenced, the working efficiency of the coal mill is greatly reduced, and people are forced to repair or replace the separator guide device.
Current separator guider is overall structure, install in the medium speed pulverizer casing through the welding mode, must cut its whole down when wearing surface wears to need repair or renew, repair and go to it welding again after accomplishing, but repair or renew the back because the wearing and tearing breach that causes when cutting makes the rewelding more difficult, and work load is big, lead to overhaul the cycle very long, even the installation does not go, waste time and energy, produce very big influence to production efficiency, and the back of current separator guider props the muscle and laminates completely through the welding mode with the back of separator welt, operating space is little when wearing surface wears to need repair, it is very inconvenient to repair, especially when the hole that grinds when being close to the position of back propping the muscle, it is just more difficult to operate to repair.
Disclosure of Invention
The utility model aims at overcoming the defect that prior art exists, provide a separator guider for medium speed coal mill that maintenance cycle is short.
Realize the utility model discloses the technical scheme of purpose is: a separator guide device for a medium-speed coal mill is provided with a cover plate, an upper supporting plate, a separator lining plate and a back supporting rib, wherein the upper supporting plate is arranged above the separator lining plate, the back of the separator lining plate is provided with the back supporting rib, and the separator guide device is of a cavity structure; go up removable apron that is equipped with in backup pad surface.
Preferably, the cover plate is arranged in several independent structures and is connected with the upper supporting plate through bolts.
Preferably, the cover plates are provided in two or three.
Preferably, a gap is formed between the back supporting rib and the back surface of the separator lining plate.
In the medium speed coal mill, 3 separator guiding devices are arranged, and are uniformly distributed in a shell of the medium speed coal mill at intervals of 120 degrees.
After the technical scheme is adopted, the utility model discloses following positive effect has:
(1) the utility model discloses a go up removable apron that is equipped with in backup pad surface to the apron sets several independent structures and passes through bolted connection with last backup pad simultaneously, grinds the back when separator guider's wearing surface, only needs to grind the apron that the hole top corresponds and demolish, and welds the wear pad of a patch formula and can reuse in the device's inner chamber, has shortened maintenance cycle greatly, makes the medium speed pulverizer can the high efficiency operation.
(2) The utility model discloses a back of back brace muscle and separator welt is equipped with the space, has great operating space when welding patch-type's wear pad in the device's inner chamber, is convenient for very much repair, especially when grinding the perforation when being close to the position of back brace muscle, big operating space has made things convenient for the quick repair of grinding the hole more.
Drawings
In order that the present invention may be more readily and clearly understood, the following detailed description of the present invention is given in conjunction with the accompanying drawings, in which
Fig. 1 is a schematic front structural view of the present invention;
fig. 2 is a schematic view of the back structure of the present invention;
FIG. 3 is a schematic view of the front side structure of the wear surface of the present invention after wearing;
FIG. 4 is a schematic front view of a prior art structure;
FIG. 5 is a schematic diagram of a prior art backside structure;
in the drawings are labeled: 1-cover plate, 2-upper supporting plate, 3-separator lining plate, 4-back supporting rib and 5-grinding hole.
Detailed Description
As shown in fig. 1-3, the utility model discloses establish at the casing inner chamber, the effect is that to make hot-air flow along specific direction in the casing, and the separator guider is the cavity structure, including apron 1, last backup pad 2, separator welt 3 and back support muscle 4, separator welt 3 top is equipped with backup pad 2, and the back of separator welt 3 is equipped with back support muscle 4, goes up removable apron 1 that is equipped with in backup pad 2 surface.
In this embodiment, apron 1 sets up to several independent structures and passes through bolted connection with last backup pad 2, separator guider's wearing surface receives the continuous impact of buggy granule under the hot-air drive, wear through very easily, separator guider's front and the side that is close to the impeller device air outlet especially, the impact that receives buggy granule is bigger, wear-out hole 5 appears more easily, only need to demolish apron 1 that wear-out hole 5 corresponds the top during repair, and weld the wear-resisting piece of a patch formula in the device's inner chamber and can reuse, this brings very big convenience for maintenance work, the maintenance cycle has been shortened, the high efficiency operation of medium speed coal pulverizer has been guaranteed.
In this embodiment, back brace 4 is equipped with the space with the back of separator welt 3, has very big repair operation space after the wearing surface of separator guider wears out, especially when wearing hole 5 is being close to the position of back brace, and big operation space has made things convenient for the quick repair of wearing hole 5 more, has shortened maintenance cycle greatly.
In the medium speed coal mill, 3 separator guiding devices are arranged, and are uniformly distributed in a shell of the medium speed coal mill at intervals of 120 degrees.
Based on the above, the utility model discloses maintenance cycle is short, has guaranteed the operation of medium speed coal pulverizer high efficiency.
The above-mentioned embodiments, further detailed description of the objects, technical solutions and advantages of the present invention, it should be understood that the above-mentioned embodiments are only specific embodiments of the present invention, and are not intended to limit the present invention, and any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the scope of the present invention.
