The double-layer cylinder structure minimizes turbulent flow, improves tail slurry discharging speed, and prolongs the service lifetime of the cylinder.

Description

A kind of double-layer barrel structure of pressurized screen
Technical field
The utility model relates to screening installation technical field, relates in particular to a kind of double-layer barrel structure of pressurized screen.
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 under 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, and underproof fiber continues to move downward, discharged by tail slurry pipe in pressurized screen bottom, be provided with into water water pipe for injecting dilution water in tail slurry pipe symmetric position.Slurry, through screen frame screening tail slurry later, need to be discharged from cylinder body bottom, and the velocity of discharge of tail slurry directly has influence on the operating efficiency of complete machine.In design in the past, tail slurry directly contacts with cylindrical shell, because cylinder body bottom space is larger, easily causes stronger turbulent flow phenomenon, reduces the slurry-outlet velocity of tail slurry, and cylindrical shell is caused compared with galling, affects the service life of cylindrical shell.
Utility model content
The utility model, in order to solve the problems of the prior art, provides a kind of double-layer barrel structure of pressurized screen, can reduce turbulent flow phenomenon, improves tail slurry slurry-outlet velocity, extends the service life of cylindrical shell.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of double-layer barrel structure of pressurized screen, comprise pressurized screen cylindrical shell, pressurized screen cylinder body bottom one side is symmetrically arranged with tail slurry pipe and water inlet pipe, on pressurized screen cylinder inboard wall, be provided with the upper reinforcing ring and the lower reinforcing ring that are arranged in order up and down, the central axes of the central axis of lower reinforcing ring and pressurized screen cylindrical shell, between described lower reinforcing ring and pressurized screen cylinder body bottom, be provided with cylinder, the central axes of the central axis of cylinder and pressurized screen cylindrical shell, the upper end of cylinder is fixedly connected with lower reinforcing ring, the lower end of cylinder is fixedly connected with the bottom of cylindrical shell, between cylinder and pressurized screen cylindrical shell, form sealed cavity, on described cylinder, the position corresponding with tail slurry pipe offers tail slurry pore, described tail slurry pipe is communicated with cylinder interior by tail slurry pore, on described cylinder, the position corresponding with water inlet pipe offers into water pore, and described water inlet pipe is communicated with cylinder interior by inlet opening.
The upper end of described cylinder and lower reinforcing ring are welded to connect, and the lower end of cylinder is connected with the bottom welding of cylindrical shell.
The beneficial effects of the utility model: in the utility model, pressurized screen cylindrical shell and cylinder coordinates, dwindle the bottom space of pressurized screen cylindrical shell, cylinder can retrain tail slurry and flow, reduce turbulent flow phenomenon, tail slurry can be discharged from tail slurry pipe fast, and make tail slurry and the isolation of pressurized screen cylindrical shell, reduce the wearing and tearing of tail slurry to pressurized screen cylindrical shell.The utility model is reasonable in design, simple in structure, be easy to manufacture, be convenient to install, and not increasing under the prerequisite of power of motor, can improve slurry-outlet velocity, and the energy conservation and consumption reduction effects of pressurized screen is significantly improved.
Brief description of the drawings
Fig. 1 is the structural representation coordinating with corollary equipment under the utility model duty;
Fig. 2 is structure top view of the present utility model.
Detailed description of the invention
As depicted in figs. 1 and 2, the double-layer barrel structure of a kind of pressurized screen of the present utility model, comprise pressurized screen cylindrical shell 1, pressurized screen cylindrical shell 1 bottom one side is symmetrically arranged with tail slurry pipe 4 and water inlet pipe 5, on pressurized screen cylindrical shell 1 inwall, be provided with the upper reinforcing ring 9 and the lower reinforcing ring 7 that are arranged in order up and down, the central axes of the central axis of lower reinforcing ring 7 and pressurized screen cylindrical shell 1, between lower reinforcing ring 7 and pressurized screen cylindrical shell 1 bottom, be provided with cylinder 2, the central axes of the central axis of cylinder 2 and pressurized screen cylindrical shell 1, the upper end of cylinder 2 and lower reinforcing ring 7 are welded to connect, the lower end of cylinder 2 is connected with the bottom welding of cylindrical shell 1, between cylinder 2 and pressurized screen cylindrical shell 1, form sealed cavity 10, on cylinder 2, the position corresponding with tail slurry pipe 4 offers tail slurry pore 3, and tail slurry pipe 4 is by tail slurry pore 3 and cylinder 2 internal communication, and on cylinder 2, the position corresponding with water inlet pipe 5 offers into water pore 6, and water inlet pipe 5 is by inlet opening 6 and cylinder 2 internal communication.
The utility model is in the time of work, be used in conjunction with corollary equipment, corollary equipment is rotor and screen frame, the slurry tail slurry that 8 screenings produce later through screen frame is come in the cylinder of pressurized screen cylindrical shell 1 bottom, in cylinder, inject dilution water from water inlet water pipe, mixed tail slurry is discharged from the tail slurry pipe 4 of pressurized screen cylindrical shell 1 bottom.Due to the existence of cylinder 2, dwindle the bottom space of pressurized screen cylindrical shell 1, cylinder 2 can retrain tail slurry and flow, reduce turbulent flow phenomenon, tail slurry can be discharged from tail slurry pipe 4 fast, and tail slurry and pressurized screen cylindrical shell 1 are isolated, reduce the wearing and tearing of tail slurry to pressurized screen cylindrical shell 1.
Through checking, the turbulence effect of the tail slurry after the utility model uses has reduced 25% before improving, and the slurry-outlet velocity maximum of tail slurry can reach 25 meters per second.The utility model is only started with from structural design, not increasing under the prerequisite of power of motor, can improve slurry-outlet velocity, and the energy conservation and consumption reduction effects of pressurized screen is significantly improved.
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.
