Specific embodiment
Further to illustrate the technical means and efficacy of the invention taken to reach above-mentioned purpose, below in conjunction with attached drawing
And preferred embodiment, a specific embodiment of the invention, structure, feature and its effect describe in detail bright, it should be understood that this hair
Bright described specific embodiment is only used to explain the present invention, is not intended to limit the present invention.
Shown in referring to Fig.1~3, a kind of plate and frame filter press blowback pipeline decreasing loss device, including it is at an angle to each other and interconnected
Blowback pipeline 1 and main pipeline 2, main pipeline 2 is fixedly installed with decreasing loss device 3 far from one end of its import, and decreasing loss device 3 includes
T font pipeline 30 and connecting flange 31, the feed inlet of T font pipeline 30 and the outlet of main pipeline 2, T font pipeline 30
301 end of first outlet is connected with buffer part 4 by connecting flange 31, high pressure gas therein carry pulp particle via
Main pipeline 2 enters in T font pipeline 30, and is connect by connecting flange 31 with the first outlet 301 of T font pipeline 30 slow
Buffering is played the role of in the counteracting that the impact force that high pressure draught can be generated by rushing portion 4 carries out a part, and then weakens slurry to T word
The impact force and mill shear force of the elbow of type pipeline 30, the amount of force of bend pipe are reduced with this, to improve at channel bend
Service life.At 302 end of second outlet of T font pipeline 30 be also communicated with pan feeding pipeline 5 simultaneously, can high pressure draught by slurry
It is blown in pan feeding pipeline 5, slurry is recycled, to lower production cost.And by curved in T font 30 inner walls of pipeline
Pipeline Curvature radius at head is in 55~58cm, and shown referring to Fig.1, existing filter press blowback pipeline 1 is in 90 degree of elbows
The radius of curvature at place 22cm~24cm but due in the high pressure gas in pipeline flow velocity quickly, existing 90 degree of elbows
The radius of curvature of pipeline is small, and pipeline concave edge can be made excessively compressed, and the excessive tension of convex edge of opposite bend pipe, causes pipe
The elbow discontinuity equalization in road, cause pipeline service life reduction, while the pipeline of elbow radius of curvature it is small will so that
The slurry flowed in pipeline, in 90 degree of elbow turn sharps, slurry can generate biggish impact force and mill shear force to elbow,
Therefore suitably the Pipeline Curvature radius at channel bend is rationally increased, the slurry in the case where high pressure gas drives will be effectively prevent
Expect that particle generates huge impact force and mill shear force in elbow, to reduce the worn out probability of pipeline.
In preferred embodiment of the present invention, referring to Fig. 2, shown in 3, buffer part 4 includes buffering pipe 40 and is buffering
Pipeline 40 is fixedly installed with block 41 far from one end of its import, and the height of block 41 is higher than outside the pipeline of buffering pipe 40
Diameter can effectively be sealed buffering pipe 40 using the above structure, prevent foreign matter impurity in external environment to starching in pipeline
The pollution of material；Simultaneously by being equipped with the elastic buffering pad 6 that can be slided on its inner wall, elasticity therein in buffering pipe 40
Cushion 6 is polyurethane cushion block, and 6 side of elastic buffering pad is fixedly connected with multiple groups spring 7, and the other end of every group of spring 7 prolongs
It extends to the side of block 41 and is fixedly connected with the side surface of block 41, wherein the peace when being installed of elastic buffering pad 6
It fills angle and horizontal direction is in 90 °~135 °, by adjusting the angle of elastic buffering pad 6 and horizontal direction, on the one hand can offset
The impact force and mill shear force of pulp particle in high pressure gas, the on the other hand effect by pulp particle to elastic buffering pad 6
Power changes its direction, enters directly into it in pan feeding pipeline 5, reduces in high-pressure slurry particle and 30 elbow of T font pipeline
The time of contact of wall, to prevent the elbow of pipeline worn out.
Concrete operating principle:
When the plate and frame filter press 8 with 2 inlet communication of main pipeline is worked, the high pressure gas in main pipeline 2 will be carried
Pulp particle object a part be circulated to blowback pipeline 1, another part high pressure gas is then flow in T font pipeline 30, wherein in T
The polyurethane cushion block that 301 end of first outlet of font pipeline 30 is equipped with will be by multiple groups compressed spring 7 and 40 end of buffering pipe
The block 41 of fixed installation connects, and goes out when another part high pressure gas carries pulp particle by the first of T font pipeline 30
When mouth 301 generates impact force and mill shear force with polyurethane cushion block, on the one hand pass through the self-deformation counteracting one of polyurethane cushion block
It is allocated as exerting oneself, most impact force is on the other hand eliminated by the elastic force of compressed spring 7 itself compression generation, so that
Slurry at channel bend inner wall impact force and mill shear force reduce, furthermore part size heap due to impact force is cut in overlay on it is poly-
Urethane cushion block is formed about pulp layer, which wraps the slurry not only carried to subsequent high pressure gas on polyurethane cushion block surface
Material play the role of reduce impact force, and pulp layer can also the surface layer to polyurethane cushion block carry out certain protection, make its by
The mill shear force arrived is reduced causes the service life of the polyurethane cushion block of end point to extend reduction production to indirect protective terminal
Cost.The direction of travel of high pressure gas can effectively be changed by adjusting the setting angle of polyurethane pad simultaneously, to reduce
The contact probability at slurry and channel bend carried in gas, further prevents slurry to the abrasion at channel bend.
The present invention provides a kind of plate and frame filter press blowback pipeline decreasing loss device, slow by the way that elasticity is arranged in buffering pipe 40
Rush pad 6 and the side of cushion be equipped with multiple groups spring 7, elastic buffering pad 6 therein with anticyclonic slurry solids particle
Contact forms first-level buffer band, then forms level 2 buffering band by the compression of multiple groups spring 7, passes through the work of this two-stage buffer strip
With, effectively balance out the impact force of slurry, in T font pipeline 30 pressure carry out discharge, reduce slurry of solids particle pair
The impact force of channel bend.
The above embodiments are only the preferred technical solution of the present invention, and are not construed as limitation of the invention, this hair
Bright protection scope should be with the technical solution of claim record, technical characteristic in the technical solution recorded including claim
Equivalents are protection scope.Equivalent replacement i.e. within this range is improved, also within protection scope of the present invention.
