Embodiment
The invention will be further described below in conjunction with drawings and Examples:
Shown in Fig. 1 to 4, the cut-up type blow-down pump of present embodiment comprises the pump housing, motor, is arranged on impeller 11 and motor shaft 5 and axle sleeve 4 in the pump housing, the pump housing is composed of a fixed connection by base 1, protecgulum 9, bonnet 3, motor shaft 5 stretches in the pump housing, and be rotationally connected with bonnet 3, impeller 11 is fixedly installed between forward and backward lid, and fixedlys connected with motor shaft 5.Protecgulum 9 bodies are provided with the material feeding mouth 10 that enters for material, shear plane 111 before the end towards protecgulum 9 of described impeller 11 forms moving knife, shear plane 111 was sheared the spirality protecgulum stationary knife 902 that cooperates before the surface that is positioned at the pump housing of described protecgulum 9 was provided with moving knife with impeller 11, described base 1 is provided with the discharge port 2 of discharging for material, the opening of this material feeding mouth 10 is made up of three sections identical curves of shape, every section curve is intersected by a spiral and a short arc line to be formed, three sections curve end-to-ends, form the material feeding mouth 10 of nearly heart type, material feeding mouth 10 adopts this kind shape, can effectively hinder long fibre and enter the pump housing, long fibre is assembled at little arcuate segment, be convenient to be cut off by impeller 11, be provided with chamfering 903 at these material feeding mouth 10 places, can improve like this long stapled cutting power, these chamfering 903 places can establish wearing layer, protecgulum stationary knife 902 is intersected by the heart type projection at identical arc-shaped protrusions of three rotation directions and material feeding mouth place and forms, the preferential end face of selecting protecgulum 9 be designed to by in the pump housing to the pump housing outside the arc-shaped curved surface 904 of protrusion, protecgulum stationary knife shear plane 901 is parallel with this arc-shaped curved surface 904; The lateral cross section of impeller 11 is " S " type, shear plane 111 before its end face towards protecgulum 9 forms moving knife, shear plane 112 after its end face towards bonnet 3 forms moving knife, shear plane 111 is sheared with protecgulum stationary knife shear plane 901 and is cooperated before the moving knife, during the arc-shaped curved surface that in protecgulum 9 is designed to by the pump housing, outside the pump housing, protrudes, the width of the blade of impeller 11 is outwards gradually narrow by the center, impeller 11 by bolt, key and thrust housing 6, screw nut 7 and fixedly connected with motor shaft 5; Be set with price fixing 8 at impeller 11 and 3 of bonnets, the one side towards impeller of this price fixing 8 is provided with the spirality price fixing stationary knife 801 that is formed by three identical arc-shaped protrusions of rotation direction, the price fixing stationary knife shear plane 802 of described price fixing stationary knife 801 cooperates with 112 shearings of shear plane behind the moving knife, above-mentioned two shear planes are the plane, the rotation direction of protecgulum stationary knife 902 and price fixing stationary knife 801 all with opposite setting of rotation direction of impeller 11, can improve shear ability like this, the end face of protecgulum 9 is arranged to arc outstanding outside the pump housing, can make the organic substance in the pump housing keep certain amount, guarantee fully to interrupt fiber, certainly, the arc-shaped protrusions that forms protecgulum stationary knife 902 and price fixing stationary knife 801 can be more than two or three, circularizes arrayed between each arc-shaped protrusions on protecgulum stationary knife 902 and the price fixing stationary knife 801.Price fixing stationary knife shear plane 802 cooperates with 112 plane shears of shear plane behind the moving knife, can the fiber after cutting off be ground, and material is fully shredded, and helps the eliminating of material and follow-up processing.In order to prolong the life-span of pollution discharge pump, chamfering 903 places that reach heart-shaped material feeding mouth on described each shear plane fixedly install wearing layer, wearing layer preferentially selects to adopt the continuous welding on chamfering 903 places and each shear plane of 5Cr5W9No2V chrome molybdenum tungsten vanadium cold-punching mould surfacing electrode to form in the present invention, the wearing layer that adopts the method to form has higher hardness and intensity and higher impact resistance, under identical Environmental Conditions, hardness and intensity all improve more than 2 times than diamondite cutter head, improve more than 4 times before wearing layer is set, its wear-resisting property correlation data sees Table 1.Price fixing 8 is sealedly and fixedly connected by the wheel hub of its axis hole and described impeller 11, pump housing inner chamber can be divided into two zones that do not communicate, and reduces the accumulation of fiber 3 of price fixing 8 and bonnets, reduces equipment failure rate.
Table 1:
The wearing layer kind Every day is the work duration effectively The life-span of cutter
Before wearing layer is set 8 hours/day 29 days
The diamondite cutter head is set 8 hours/day 84 is big
The anti-welding mill of 5Cr5W9No2V chrome molybdenum tungsten vanadium layer is set 8 hours/day 176 days
During the work of this machine, when the ight soil that contains impurity such as long fibre enters material feeding mouth 10, under the effect of centrifugal force and semiclosed impeller 11, material is the outer side shifting of mind-set therefrom, and the impeller 11 that enters high speed rotating with before, between the bonnet, the protecgulum end face the little arc section at heart-shaped material feeding mouth 10 places long fibre can be assembled, can effectively hinder long fibre enters in the pump housing, long fibre cuts off in material feeding mouth 10 places chamfering 903, enter 9 of impeller 11 and protecgulums, impeller is convenient further to cut off long fibre with the opposite direction active force, then enters between price fixing 8 and the impeller 11 again, grind again, enter pump chamber at last and transfer out by discharge port 2.
