Description
Technical field
The utility model relates to mining machinery field, particularly one material mouth sealing device.
Background technique
In the middle of some mining machineries, the discharge port of equipment and material feeding mouth and extraneously there is certain pressure difference, during production, the gas of equipment class is ventilated outward from feed inlet and outlet toward equipment under the effect of pressure difference, not only cause the waste on the energy, and the gas run out of usually mixes and has dust, not only affect the operation of field personnel and healthy, also can leave the potential safety hazard of dust explosion, therefore, need to arrange a seal arrangement at feed inlet and outlet place, the seal arrangement arranged not only will ensure that safety and stability is reliable, its cost also will be made low, easy accessibility, long service life, simultaneously, also need the pressure difference in maintenance equipment, do not affect the normal operation of equipment.
Model utility content
Goal of the invention of the present utility model is: for above-mentioned Problems existing, provides a kind of material mouth sealing device, under the equipment that do not affect normally works, make the sealing effect that seal arrangement reaches good, meanwhile, make seal arrangement easy accessibility, safe and reliable, long service life, input cost is low.
The technical solution adopted in the utility model is as follows: a kind of material mouth sealing device, comprise barrel, upper end on described barrel is bonded with a stuffing box gland, the lower end of described stuffing box gland is bonded in barrel bottom, and stuffing box gland is arc circle nested structure, and the middle part inwall of described arc circle nested structure is provided with a valve, described valve is two half moon thin slices, toward each other, root is connected with stuffing box gland inwall, and the free edge of valve is towards Flow of Goods and Materials direction.
Due to above-mentioned vibrational power flow, when material enters from material mouth or goes out from material mouth time, stuffing box gland can be close to material, but the inhibition produced is very little, can ignore on the impact of the motion of material, due to the existence of pressure difference, the most gases in equipment will be closed in equipment by stuffing box gland, reach good sealing effect; The valve that in blood vessel, resistant to blood flows backwards is imitated in the design of valve, and principle broadly similar, because the gas pressure intensity in equipment is greater than outside pressure, this just forces the valve in stuffing box gland to be fitted to centre, because valve is crescent shape, without any gap after making valve fit, reach sealing purpose, material then enters from the opposite direction of valve, and material backs down the laminating of two valves, and valve then can be close to material surface, after material passes through, valve can continue again laminating, continues sealing, therefore significant sealing affection.Meanwhile, consider convenient installation, abutting edge can be arranged on material mouth outside, even if after the impaired inefficacy of stuffing box gland, by using solvent to make the glue of abutting edge dissolve, stuffing box gland self falling, reaches the object of easy accessibility.
Further, described stuffing box gland inwall is coated with one deck and increases sliding wearing layer, the sliding wearing layer of described increasing is that one deck waterborne organic silicon increases sliding wear-resistant paint.
Further, the thickness of described stuffing box gland is 0.5-5mm, bonding with barrel joint aqua type synthetic resin glue, adhesion width is 5-20mm, bonding location barrel inwall or stretch out barrel outer wall, the sliding wearing layer thickness of described increasing is 150-500 μm, the thickness of described valve is 3-8mm, root epoxyn is bonded in stuffing box gland inwall, and valve surface is also coated with one deck waterborne organic silicon and increases sliding wear-resistant paint, and coating layer thickness is 500-1000 μm.
Consider stuffing box gland sealability and stability, in installation, ensure that abutting edge bond area is large as far as possible, bonding solid and reliable.Due to stuffing box gland employing is macromolecular material, has certain viscosity, can be very large to the inhibition of material, therefore apply one deck at stuffing box gland inwall and increase sliding wearing layer, increase the sliding capability of stuffing box gland on the one hand, reduce stuffing box gland to the inhibition of material, reduce friction; Increase the wear resistance of stuffing box gland on the other hand, reduce damage and the scraping of stuffing box gland, improve the usability of stuffing box gland.In addition, because material surface is close to by valve or the circle that concaves, wear and tear the most serious, the obstruction caused material is also maximum, therefore valve or the sliding wearing layer of increasing of a circle coating that concaves thicker, improve the performance of stuffing box gland further, increase working life.
In sum, owing to have employed technique scheme, the beneficial effects of the utility model are:
1, sealing device structure is simple, good sealing effect, and device is stablized, safe and reliable.
2, seal arrangement easy accessibility, easy to use, works almost without impact with normal on the structure of apparatus body.
3, the mechanical property of seal arrangement and mechanical property good, the working life of seal arrangement is extended, and reduces replacement cost further.
Accompanying drawing explanation
Fig. 1 is one material mouth sealing device structural representation of the present utility model.
Mark in figure: 1 is barrel, and 2 is stuffing box gland, and 3 is valve, 4 for increasing sliding wearing layer.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
In order to make the object of model utility, technological scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1, a kind of material mouth sealing device, comprise barrel 1, the upper end on described barrel 1 is bonded with a stuffing box gland 2, and the lower end of described stuffing box gland 2 is bonded in barrel 1 bottom, stuffing box gland 2 is arc circle nested structure, the middle part inwall of described arc circle nested structure is provided with a valve 3, and described valve 3 is two half moon thin slices, toward each other, root is connected with stuffing box gland 2 inwall, and the free edge of valve 3 is towards Flow of Goods and Materials direction; Described stuffing box gland 2 inwall is coated with one deck and increases sliding wearing layer 4, the sliding wearing layer 4 of described increasing is sliding wear-resistant paint for one deck waterborne organic silicon increases.
In an embodiment of the present utility model, the thickness of described stuffing box gland 2 is 2mm, bonding with barrel 1 joint aqua type synthetic resin glue, adhesion width is 10mm, bonding location barrel 1 inwall or stretch out barrel 1 outer wall, sliding wearing layer 4 thickness of described increasing is 300 μm, the thickness of described valve 3 is 5mm, root epoxyn is bonded in stuffing box gland 2 inwall, and valve surface is also coated with one deck waterborne organic silicon and increases sliding wear-resistant paint, and coating layer thickness is 800 μm.
In an embodiment of the present utility model, the thickness of described stuffing box gland 2 is 5mm, bonding with barrel 1 joint aqua type synthetic resin glue, adhesion width is 20mm, bonding location barrel 1 inwall or stretch out barrel 1 outer wall, sliding wearing layer 4 thickness of described increasing is 150 μm, the thickness of described valve 3 is 8mm, root epoxyn is bonded in stuffing box gland 2 inwall, and valve surface is also coated with one deck waterborne organic silicon and increases sliding wear-resistant paint, and coating layer thickness is 500 μm.
