Description
Technical field
The utility model relates to screening installation technical field, relates in particular to a kind of novel pressure sieve.
Background technology
The operation principle of pressurized screen is, slurry is oriented in a tangential direction and enters the top separation chamber of pressurized screen, heavier object is dumped into heavy slag pipe in the effect of centrifugal force, slurry after slagging-off enters screen frame and rotor revolves the screening area between cylinder, acceptable fiber is drawn by good slurry pipe by sieve aperture, underproof fiber, continues to move downward, and is discharged by tail slurry pipe in pressurized screen bottom.The downside of the upper cover of tradition pressurized screen is plane, and upper cover has no effect for the performance boost of pressurized screen itself, only plays sealing function.And the cylindrical shell of traditional pressurized screen is cylindrical tubular structure, such tube structure coordinates with traditional upper cover, can make pressurized screen upper cover and cylindrical shell between there is larger space, slurry just can enter screening region after must flowing in this segment space.In this process, the speed of slurry stream can decline, and is entering behind screening area, and rotor need to accelerate again to slurry, to reach the screening effect needing.This will inevitably increase the power consumption of rotor.
Utility model content
The utility model is in order to solve the problems of the prior art, and a kind of novel pressure sieve is provided, and can dwindle the space between upper cover and the cylindrical shell of pressurized screen, improves slurry and leave the speed in this space, reduces the consumption of rotor power.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of novel pressure sieve, comprise the cylindrical shell and the upper cover that is fixedly installed on cylindrical shell upper end of pressurized screen, in the cylindrical shell of pressurized screen, be provided with rotor, rotor is arranged with screen frame outward, screen frame is fixedly connected with cylinder lateral wall, the position that is positioned at rotor top on cylinder lateral wall is provided with pulp-inlet pipe, position corresponding with screen frame bottom on cylinder lateral wall is provided with grout outlet, cylinder body bottom is provided with tail slurry pipe, the position that described upper cover lower end is positioned at inner barrel is fixedly installed back taper gland, larger one end of back taper gland is fixedly connected with upper cover, less one end of back taper gland is positioned at the top of rotor, the axis of back taper gland and the axis of rotor are positioned at same straight line, described cylindrical shell is up-small and down-big taper type cylindrical shell.
Described pulp-inlet pipe is positioned at the less position of described taper type barrel diameter.
The described axis of taper type cylindrical shell and the axis of described rotor are positioned at same straight line.
Between the cylindrical shell of described pressurized screen and upper cover, be bolted.
The beneficial effects of the utility model: in the utility model, back taper gland and taper type cylindrical shell coordinates, dwindle the space between upper cover and the cylindrical shell of pressurized screen, when slurry enters after inner barrel, under the effect of back taper gland and taper type cylindrical shell, can come together to the screening area at cylindrical shell center rapidly, minimum on the impact of plasma flow velocity, make slurry in the time entering into screening region, certain speed can be kept, the consumption of rotor power can be reduced; Pulp-inlet pipe is positioned at the position that taper type barrel diameter is less, can make the more close screen frame in position after slurry enters, and the opposite force of cone, can further slurry be pushed screen to region, and slurry can enter screening region with the fastest speed.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
As shown in Figure 1, a kind of novel pressure sieve of the present utility model, comprise the cylindrical shell 1 and the upper cover 5 that is fixedly installed on cylindrical shell 1 upper end of pressurized screen, between upper cover 5 and cylindrical shell 1, be bolted, in the cylindrical shell 1 of pressurized screen, be provided with rotor 3, the outer screen frame 7 that is arranged with of rotor 3, screen frame 7 is fixedly connected with cylindrical shell 1 sidewall, the position that is positioned at rotor 1 top on cylindrical shell 1 sidewall is provided with pulp-inlet pipe 6, position corresponding with screen frame 7 bottoms on cylindrical shell 1 sidewall is provided with grout outlet 2, cylindrical shell 1 bottom is provided with tail slurry pipe 8, the position that the lower end of upper cover 5 is positioned at cylindrical shell 1 inside is fixedly installed back taper gland 4, larger one end of back taper gland 4 is fixedly connected with upper cover 5, less one end of back taper gland 4 is positioned at the top of rotor 3, the axis of the axis of back taper gland 4 and rotor 3 is positioned at same straight line, cylindrical shell 1 is up-small and down-big taper type cylindrical shell, and pulp-inlet pipe 6 is positioned at the position that taper type barrel diameter is less, and the axis of the axis of taper type cylindrical shell and rotor 3 is positioned at same straight line.
The utility model is in the time of work, slurry enters into inner barrel from pulp-inlet pipe 6, due to coordinating of back taper gland 4 and taper type cylindrical shell, dwindle the space between upper cover 5 and the taper type cylindrical shell of pressurized screen, when slurry enters behind cylindrical shell 1 inside, under the effect of back taper gland 5 and cylindrical shell 1, can come together to the screening area at cylindrical shell 1 center rapidly, impact on plasma flow velocity is minimum, make slurry in the time entering into screening region, can keep certain speed, can reduce the consumption of rotor 3 power, and enter slurry 6 pipes be positioned at the position that taper type barrel diameter is less, can make the more close screen frame 7 in position after slurry enters, and the opposite force of cone, can further slurry be pushed screen to region, slurry can enter screening region with the fastest speed, heavier object is dumped into tail slurry pipe 8 in the effect of centrifugal force afterwards, slurry after slagging-off enters the screening area between screen frame 7 and rotor, acceptable fiber is drawn by grout outlet 2 by sieve aperture, underproof fiber, continue to move downward, discharged by tail slurry pipe 8 in pressurized screen bottom.
Above embodiment is the unrestricted the technical solution of the utility model in order to explanation only, although the utility model is had been described in detail with reference to above-described embodiment, those of ordinary skill in the art is to be understood that: still can modify or be equal to replacement the utility model, and not departing from any modification or partial replacement of spirit and scope of the present utility model, it all should be encompassed in the middle of claim scope of the present utility model.
