Description

Leak-proof cover plate for coal crusher

Technical Field

The utility model relates to a coal breaker, especially a leak protection apron for coal breaker.

Background

The general formula structure as an organic whole of present coal breaker apron, the outside of apron and the lateral wall interconnect of coal breaker, the middle part and the coal leakage fill integrated into one piece of apron. However, when the coal breaker is in actual use, the side wall of the coal leakage hopper of the coal breaker is often deformed and damaged under the falling impact of the coal, so that the coal leakage phenomenon occurs. And because the mode of wholly changing the apron can cause the increase of replacement cost, lead to at present the producer to generally carry out the repair welding by the manual work to breach department after the coal leakage fill is damaged. However, the treatment mode is not only complicated in operation, but also the repair frequency of the coal leakage hopper is gradually frequent along with the increase of the service time of the coal leakage hopper, so that the labor capacity of workers is increased. Therefore, the existing coal breaker cover plate has the problems of high replacement cost and difficulty in repairing.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a coal breaker is with leak protection apron. It has the characteristics of high structural stability and low replacement cost.

The technical scheme of the utility model: leak protection apron for coal breaker, including the upper cover plate, the middle part of upper cover plate is equipped with the coal breakage mouth, and the outside of coal breakage mouth can be dismantled and be connected with the coal leakage fill, the coal leakage fill includes the reducing pipe, and the lower extreme of reducing pipe is connected with the mounting panel, through brace diagonal interconnect between the outer wall of mounting panel and reducing pipe, and the inboard of mounting panel is equipped with the location ring body, and the lower extreme of location ring body inserts the coal breakage mouth, and the upper end and the reducing pipe of location ring body weld each other.

In the leakage-proof cover plate for the coal crusher, the peripheral edge of the coal dropping opening is an inclined surface, and the outer side of the positioning ring body is provided with a flexible gasket which is mutually attached to the inclined surface.

In the aforesaid leak protection apron for coal pulverizer, the inclined plane is 5 ~ 15 at the ascending contained angle of vertical direction.

In the anti-leakage cover plate for the coal crusher, the mounting plate is connected with the upper cover plate through the bolt threads, and the bolts are symmetrically arranged on two sides of the inclined ribs.

Compared with the prior art, the coal leakage hopper is detachably connected with the upper cover plate, so that the coal leakage hopper can be independently replaced after being damaged, and the replacement cost of the coal leakage hopper is effectively reduced; through the structural matching of the mounting plate and the inclined ribs, the structural strength and the deformation resistance of the reducer pipe can be improved, and the structural stability of the coal leakage hopper is further improved; the positioning ring body and the coal dropping opening are buckled with each other, so that a limiting effect can be achieved on the coal leaking hopper, vibration of the coal leaking hopper during coal dropping caused by an installation gap is reduced, and the structural stability of the coal leaking hopper is further improved; through the matching of the inclined plane and the flexible gasket, on one hand, the requirements on the size precision of the coal dropping port and the positioning ring body can be reduced, and the processing of the utility model is convenient; on the other hand can also guarantee the laminating completely of location ring body and inclined plane behind the coal leakage fill pressfitting to improve the utility model discloses a spacing and damping effect. Therefore, the utility model has the characteristics of structural stability is high, replacement cost is low.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

The labels in the figures are: 1-upper cover plate, 2-reducer pipe, 3-mounting plate, 4-inclined rib, 5-positioning ring body, 6-flexible gasket and 101-coal dropping port.

Detailed Description

The following description is made with reference to the accompanying drawings and examples, but not to be construed as limiting the invention.

Examples are given. Leak protection apron for coal pulverizer constitutes as shown in fig. 1, and including upper cover plate 1, the middle part of upper cover plate 1 is equipped with coal breakage mouth 101, and the outside of coal breakage mouth 101 can be dismantled and be connected with coal leakage fill, coal leakage fill includes reducing pipe 2, and the lower extreme of reducing pipe 2 is connected with mounting panel 3, through 4 interconnect of diagonal rib between mounting panel 3 and the outer wall of reducing pipe 2, and the inboard of mounting panel 3 is equipped with the locating ring body 5, and coal breakage mouth 101 is inserted to the lower extreme of locating ring body 5, and the upper end and the reducing pipe 2 of locating ring body 5 weld each other.

The periphery of coal breakage mouth 101 is the inclined plane, the lateral wall of locating ring body 5 is the inclined plane with inclined plane complex, and the outside of locating ring body 5 is equipped with the flexible packing ring 6 of laminating each other with the inclined plane.

The inclined plane is 5 ~ 15 at the ascending contained angle of vertical direction.

The mounting plate 3 is connected with the upper cover plate 1 through bolt threads, and bolts are symmetrically arranged on two sides of the inclined ribs 4.

The utility model discloses a theory of operation: the utility model discloses when the installation, earlier set up coal breakage mouth 101 at the middle part of current upper cover plate 1 to set up the screw hole around coal mouth 101, simultaneously with the independent weld forming of coal leakage fill. After the coal leakage hopper is formed, the positioning ring body 5 at the lower end of the coal leakage hopper is inserted into the coal dropping opening 101, and the flexible gasket 6 is attached to the inclined surface at the edge of the coal dropping opening 101; then the coal leakage hopper is fixed on the upper cover plate 1 through the matching of the bolt and the mounting plate 3. Through the angle to the inclined plane injects for flexible packing ring 6 is being laminated completely and extrusion deformation with the inclined plane gradually along with the bolt is screwed, thereby utilizes the cooperation on the inclined plane of flexible packing ring 6 to carry out spacing and damping to coal leakage fill, receives the impact vibration when avoiding coal leakage fill's fire coal to drop, has improved coal leakage fill's structural stability and life. After the breakage appears in the coal leakage fill, the producer only needs to change after dismantling the coal leakage fill, and undamaged upper cover plate 1 then can use for a long time to it is right to effectively reduce the utility model discloses a replacement cost.
