Abstract
The utility model belongs to a sealing device for a slurry pump for a mine, and particularly relates to a convex sealing flange gasket. The flange gasket is arranged between a slurry pump and a flange and is connected with the slurry pump and the flange in a pressed manner by using bolts; a flange sleeve is arranged on the outer side of a steel pipe and is fixedly connected with the outer wall of the steel pipe; and a ceramic layer is adhered to the inner wall of the steel pipe. The convex sealing flange gasket is characterized in that the flange gasket is convex, the bottom of the flange gasket is disc-shaped, the upper portion of the flange gasket is projected and barrel-shaped, the disc-shaped portion of the flange gasket is arranged between the flange and the slurry pump and is connected with the flange and the slurry pump in the pressed manner by using the bolts, the barrel-shaped portion of the flange gasket is positioned in the inner cavity of the steel pipe, the diameter of the outer wall of the barrel-shaped portion is equal to the diameter of the inner wall of the ceramic layer of the inner wall of the steel pipe, the height of the outer wall of the top of the barrel-shaped portion is greater than that of the inner wall of the top of the barrel-shaped portion, and a slope is formed between the outer wall of the top of the barrel-shaped portion and the inner wall of the top of the barrel-shaped portion. The convex sealing flange gasket has the advantages that the convex sealing flange gasket is low in cost and high in sealing effect; pulp media can be prevented from directly abrading a connector, which is connected with the ceramic steel pipe, of the flange; repair workload is reduced; the productivity is improved; consumption of spare parts is reduced; and the production cost is reduced.
Description
Technical field
The utility model belongs to a kind of mine slag stock pump seal arrangement, particularly a kind of convex sealing flange pad.
Background technique
Current mine slag stock pump pump discharge is plain cushion flange gasket, adopts reclaimed rubber material to make.Ore pulp medium, under the effect of slag stock pump centrifugal force, is flowed into by flange bottom, directly washes away ceramic steel pipe, because steel pipe does not have ceramic layer wear-resisting, thus between ceramic layer and flange, be washed out annular groove, until tube wall mill is leaked.
Plain cushion flange gasket can only seal plane between two flanges, and can not reduce the wearing and tearing of ore pulp medium to flange and ceramic steel pipe.Sealing intensity is low, wears no resistance, and increases thus spare parts consumption, improves cost of production, increases maintenance workload.
Summary of the invention
The purpose of this utility model is to provide a kind of sealing that can guarantee between flange contact facings, can solve again flange and Ceramo-steel interface tube place sealing flange pad easy to wear, to reduce spare parts consumption, reduces production costs, and alleviates maintenance workload.
The purpose of this utility model is achieved through the following technical solutions:
Convex sealing flange pad of the present utility model, flange gasket is between slag stock pump and flange and by bolt and slag stock pump and flange crimping, flange is enclosed within steel pipe outside and is fixedly connected with outer wall of steel pipe, steel pipe inner wall is attached with ceramic layer, it is characterized in that: described flange gasket is convex, bottom is disc, top is protruding cylindrical shape, disc part is between flange and slag stock pump, by bolt crimping, cylindrical shape is partly positioned at steel pipe inner chamber, cylindrical outer wall diameter equals steel pipe inner wall ceramic layer inner diameter, cylindrical shape top outer wall height is higher than inside wall height, between the outer wall inwall of cylindrical shape top, become domatic.
Described flange gasket upper lobes cylindrical outer wall length is 1/4-1/2 of outer wall of steel pipe diameter.
In practical work process, ore pulp medium is under the effect of slag stock pump centrifugal force, by flange bottom, flowed into, owing to having packed convex sealing flange pad between slag stock pump and flange, the cylindrical shape of this convex sealing flange pad has partly been protected the ceramic layer of steel pipe, thereby has greatly increased the working life of flange.
And cylindrical shape top outer wall height is higher than inside wall height, between the outer wall inwall of cylindrical shape top, become domatic, be easy to reduce the resistance that ore pulp meson refluxes.
The utility model has the advantages that: cost is low, good sealing effect, can avoid the directly wearing and tearing to flange and Ceramo-steel interface tube place of ore pulp medium, alleviates maintenance workload, boosts productivity, and reduces the consumption of standby redundancy, reduces production costs.
Accompanying drawing explanation
Fig. 1 is this practical new structure schematic diagram.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, a kind of convex sealing flange pad of the present utility model, flange gasket 2 is between slag stock pump 1 and flange 3 and by bolt 4 and slag stock pump 1 and flange 3 crimping, flange 3 is enclosed within steel pipe 5 outsides and is fixedly connected with steel pipe 5 outer walls, steel pipe 5 inwalls are attached with ceramic layer 6, it is characterized in that: described flange gasket 2 is convex, bottom is disc, top is protruding cylindrical shape, disc part is between flange 3 and slag stock pump 1, by bolt 4 crimping, cylindrical shape is partly positioned at steel pipe inner chamber 7, cylindrical outer wall diameter equals steel pipe 5 internal wall ceramic layer 6 inner diameter, cylindrical shape top outer wall height is higher than inside wall height, between the outer wall inwall of cylindrical shape top, become domatic.
Described flange gasket 2 upper lobes cylindrical outer wall length are 1/4-1/2 of steel pipe 5 outer diameters.
