Abstract
The utility model discloses a pusher in the mechanical field, and concretely relates to a high efficient anti-blocking spiral pusher for a centrifuge, comprising a blade (1), a small straight pipe (2), a material feeding pipe sleeve (3), a material feeding pipe (4), a welding sleeve (5), a material discharging pipe sealing plate (6), a small taper pipe (7), a material discharging pipe (8), and a material outlet (9), the pusher is characterized in that: a cloth taper pipe (12) is increased in the small taper pipe (7), the cloth taper pipe (10) extends from the end of the material feeding pipe sleeve (3) to the starting end of the material discharging pipe and gradually turns larger in a radial direction. The effect of the pusher in the utility model is that: the pusher reduces wearing of drilling fluid waiting to be processed upon spiral, prolongs life of spiral, prevents friction with spiral and breaking of material feeding pipe due to overlong material feeding pipe, is not easy to obstruct, and reduces wearing of spiral pusher.
Description
Technical field
The utility model relates to a kind of pusher of mechanical field, is specifically related to a kind of centrifuge with efficient anti-blocking screw feeder.
Background technology
The drilling fluid of explorations such as petroleum gas and production drilling well is a kind of water base suspension or oil-based suspension that contains a lot of insoluble solid phase particles.In drilling fluid was handled, centrifuge was commonly used to separate cutting grain tiny in the drilling fluid, also is used for the recovery as drilling fluid weighting materials such as barites.Centrifuge relies on the rotary drum of rotation at a high speed, and the drilling fluid that drives in the rotary drum rotates at a high speed, produces the centrifugal force that is equivalent to hundreds of and even several thousand acceleration of gravity, forces the solid phase particles in the drilling fluid to be deposited on the drum inner wall rapidly.Feed pipe is continuously sent into bowl in by the screw feeder inner chamber drilling fluid, the solid formation that is deposited on the drum inner wall is scraped rotary drum continuously by screw feeder, simultaneously, in an other side of rotary drum, the ring-shaped liquid of having removed the clarification of cutting grain flows out outside the rotary drum continuously by one group of spout hole.
Present common screw feeder is by a core tube and welds superincumbent one group of spiral blade and constitute that spiral blade blows the solid phase that is deposited on the drum inner wall off.There is one group of discharging opening radially the centre of core tube, and near non-rotary feed pipe reached discharging opening along the axis of rotation of core pipe, pending drilling fluid entered rotary drum through feed pipe by screw feeder.The discharging opening of this pusher only is a radial bore of having opened several circles or strip on the core tube simply, does not consider the waterpower movement tendency of liquid.Be easy to generate screw feeder during on-the-spot the use and stop up, the screw feeder wearing and tearing, feed pipe such as rubs at fault, has had a strong impact on the normal use of centrifuge.
The utility model content
The utility model has overcome the deficiencies in the prior art, provide a kind of centrifuge with efficient anti-blocking screw feeder, the spiral that has caused because of the drilling fluid skewness when having solved existing propeller and using stops up serious, the screw feeder serious wear, and feed pipe such as rubs easily at problem.
For solving above-mentioned technical problem, the utility model by the following technical solutions:
A kind of centrifuge is with efficient anti-blocking screw feeder, comprise blade, little straight tube, charging pipe box, feed pipe, weldering cover, discharge nozzle shrouding, little Taper Pipe, discharge nozzle and discharging opening, set up a cloth Taper Pipe in little Taper Pipe, this cloth Taper Pipe extends to discharge nozzle top and radially becomes big gradually from the charging catheter end.
For better realizing technique effect of the present utility model:
Described cloth Taper Pipe inwall and discharging opening are provided with one deck wearing layer.
Described root of blade has flowing hole.
Compared with prior art, the beneficial effects of the utility model are: set up a cloth Taper Pipe in little Taper Pipe, pending drilling fluid arrives the cloth Taper Pipe through feed pipe, flow out from discharging opening after on the cloth Taper Pipe, evenly distributing, be difficult for stopping up and reducing of the wearing and tearing of pending drilling fluid, increase the spiral life-span, dwindle feed pipe length simultaneously spiral, avoided long and spiral friction, rubbed feed pipe because of feed pipe; Cloth Taper Pipe inwall and discharging opening are provided with one deck wearing layer, have further reduced the wearing and tearing of screw feeder.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is that the utility model A is to structural representation.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further elaborated.
As shown in Figure 1, a kind of centrifuge is with efficient anti-blocking screw feeder, comprise blade 1, little straight tube 2, charging pipe box 3, feed pipe 4, weldering cover 5, discharge nozzle shrouding 6, conelet pipe 7, discharge nozzle 8 and discharging opening 9, set up a cloth Taper Pipe 10 in conelet pipe 7, this cloth Taper Pipe 10 extends to discharge nozzle 8 tops and radially becomes big gradually from charging pipe box 3 ends; Cloth Taper Pipe 10 and discharging opening 9 inwalls are provided with one deck wearing layer 11; Described blade 1 root has flowing hole 12.
During the utility model operation, drilling fluid enters in the cloth Taper Pipe 10 by feed pipe 4, because of making drilling fluid, the effect of rotary centrifugal force on cloth Taper Pipe 10, distributes uniformly earlier, enter discharge nozzle 8 again, enter in the rotary drum by discharging opening 9, thereby reduced of the wearing and tearing of pending drilling fluid, set up one deck wearing layer on cloth Taper Pipe 10 and the discharging opening 9 and further reduced wearing and tearing spiral; Because many length of cloth Taper Pipes 10 between feed pipe 4 and the discharge nozzle 8, thereby shortened the length of feed pipe, avoided because of feed pipe long with the spiral friction, rub feed pipe.In addition, as shown in Figure 2, the straight section root of blade has flowing hole, after pending drilling fluid arrived rotary drum, solid phase was blown off by blade, discharged rotary drum from the rotary drum small end, know and fall to be harmful to solid phase or bar drilling fluid, by the big end of rotary drum, finish the processing of drilling fluid at last through flowing hole.
Claims (3)
1. a centrifuge is with efficient anti-blocking screw feeder, comprise blade (1), little straight tube (2), charging pipe box (3), feed pipe (4), weldering cover (5), discharge nozzle shrouding (6), little Taper Pipe (7), discharge nozzle (8) and discharging opening (9), it is characterized in that: set up a cloth Taper Pipe (10) in little Taper Pipe (7), this cloth Taper Pipe (10) extends to discharge nozzle (8) top and radially becomes big gradually from charging pipe box (3) end.
