Detailed description of the invention
In order to make the advantage of the purpose of this utility model and technical scheme clearly understand, below in conjunction with accompanying drawing and example, the utility model is further elaborated.
As shown in Figure 1, a kind of water treatment belt filter press automatic flushing device, device comprises upper cover plate 1 and lower shoe 2, and described upper cover plate 1 and lower shoe 2 form an airtight cleaning cabin 3.The gateway 5 for guipure 4 movement is provided with in the left and right sides in described cleaning cabin 3.Be provided with one group of cleaning brush roll 6 at the middle part in described cleaning cabin 3, and be connected with the drive unit be arranged on outside described cleaning cabin 3.Guipure 4 passes in the middle of described one group of cleaning brush roll 6.Be provided with some jet pipes 7 along described cleaning cabin 6 inwall, described jet pipe 7 is provided with some nozzles 8.Described jet pipe 7 is connected with a triple valve 9 by pipeline.The bypass pipe of described triple valve 9 is connected with jet pipe 7, and straight pipe is connected with air compression plant 10 and high-pressure water device 11 respectively, pipeline is respectively equipped with electromagnetic valve I 12 and electromagnetic valve II 13.Described high-pressure water device 11 adopts running water or the sewage water after Separation of Solid and Liquid.
As shown in Figure 2, described nozzle 8 is made up of Drainage Section 8-1, diversion section 8-2 and jet segment 8-3, and described Drainage Section 8-1 becomes hollow cylinder with jet segment 8-3, and the radius R 1 of described Drainage Section 8-1 is 10 times of described jet segment 8-3 radius R 2.
The radius R 1 of described Drainage Section 8-1 is 10mm, and described jet segment 8-3 radius R 2 is 1mm.
Derive according to the incompressible principle of fluid:
S1*U1*T=S2*U2*T
л*R1*R1*U1*T=л*R2*R2*U2*T
U2/U1=（R1*R1）/（R2*R2）=100
S1: the cross-sectional area of diversion section 8-1
S2: the cross-sectional area of jet segment 8-3
U1: the flow rate of liquid in diversion section 8-1
U2: the flow rate of liquid in jet segment 8-3
T: time.
Flushing water is approximately 100 times of the speed of refluence section 8-1 from the speed that jet segment 8-3 sprays, and greatly improves the ability to guipure 4 surface washing.
Described nozzle 8 and guipure 4 surface is vertical or in 60 ~ 85 ° of angles, ensures the vertical flushing of guipure 4 or tilts to rinse, raising rinse capability.
The direction of rotation of described cleaning brush roll 6 is contrary with the direction of motion of guipure, assists and scrubs guipure 4 surface, shortens scavenging period.
When described electromagnetic valve I 12 works, described electromagnetic valve II 13 is closed; When described electromagnetic valve I 12 is closed, described electromagnetic valve II 13 works.The working time of described electromagnetic valve I 12 and electromagnetic valve II 13 is 30 ~ 90s.Jet pipe 7 is utilized alternately to adopt water and air to purge belt surface.
The width in described cleaning cabin 3 is greater than the width of guipure 4, guarantees to rinse whole guipure 4.
The quantity in described cleaning cabin 3 is 1 ~ 4, is connected in series, and can carry out multistep treatment, mention the cleaning performance to guipure 4 surface according to actual conditions.
Described jet pipe 7 is arranged alternatively up and down, and the upper and lower surface of guipure 4 all can be flushed to.
Working method of the present utility model is:
Guipure 4 passes and keeps mobile in cleaning cabin 3.Electromagnetic valve I 12 is opened, and electromagnetic valve I 13 is closed.The compressed air produced in air compression plant 10 delivers to jet pipe 7 place through pipeline, then carries out air purging from nozzle 8 ejection to guipure 4 upper and lower surface.After work 30 ~ 90s, electromagnetic valve I 12 is closed, and electromagnetic valve I 13 is opened.Hydraulic pressure in air water device 11 delivers to jet pipe 7 place through pipeline, then carries out water purging from nozzle 8 ejection to guipure 4 upper and lower surface.Then above step is repeated.
