Specific embodiment
The utility model is described in detail with reference to the accompanying drawings and examples.
As illustrated in fig. 1 and 2, a kind of backwash mechanism for cylinder type filter net, 1 horizontal type of strainer are arranged on solid-liquid point
In disembarking, which includes inverse-U-shape rack 2, jet pipe 3, scraper 4 and roller group 5, and the jet pipe 3 and scraper 4 are along filter
The central axes of net 1 are horizontally installed in the inverse-U-shape rack 2, and the scraper 4 is in the lower section of jet pipe 3；The filter wall of the strainer 1
It is arranged between the jet pipe 3 and scraper 4, and the inner surface for filtering wall is in contact with the knife face of the scraper 4；3 face of jet pipe
The side of the strainer 1 is provided with several nozzles, the jet pipe 3 is provided with water inlet/air inlet；The roller group 5 is set
In the outer wall of the strainer 1 the strainer 1 to be driven to rotate.
The backwash mechanism for being used for cylinder type filter net uses the filter wall of jet pipe 3 and 4 matched mode of scraper to strainer 1
It is cleaned, after solid-liquid separating machine often works a period of time, high pressure water/height is passed through from water inlet/air inlet of the jet pipe 3
Calm the anger, and start the roller group 5 and rotated with electric filter 1, strainer 1 can be rinsed, cleaning performance uniformly, without dead angle
And it is efficient, the jet pipe 3 has still been carried out at the same time cleaning to the scraper 4, has been scraped described in holding while strainer 1 is cleaned
The cleaning of knife 4.
In specific implementation, the strainer 1 and backwash mechanism are arranged in solid-liquid separating machine, the back-flushing structure
Inverse-U-shape rack 2 is fixed in solid-liquid separating machine, and the roller group 5 is by rotating axis connection driving motor with 1 turn of electric filter of band
It is dynamic.
Preferably, as shown in figure 3, the scraper 4 and jet pipe 3 are staggered, so that the strainer 1 filters wall in rotation
The scraper 4 is first passed through using the jet pipe 3.
Due to being attached to the typically high viscosity such as dregs on the filter wall of strainer 1, when rinsing, first with the scraper
4 scrape off highly viscous dregs, then are rinsed the efficiency that can improve flushing to the filter wall of strainer 1 with the jet pipe 3.
4 preferred elastomeric material of scraper makes, and is preferably but not limited to rubber or latex or silica gel etc..
The strainer 1 is because of the reason of making filter opening, and there may be the hangnail of protrusion, the scraper 4 to use at filter opening edge
Elastic material making can provide certain elasticity and buffer capacity, and scraper 4 is avoided to be blocked by the hangnail of the strainer 1 and is influenced
The work of the backwash mechanism or even damage solid-liquid separating equipment.
Further, it is described in order to avoid the scraper 4 is blocked in cleaning process by the hangnail on the strainer 1
It is elastic connection between scraper 4 and inverse-U-shape rack 2, so that the scraper 4 has certain mobile space in the vertical direction,
Play cushioning effect；As shown in figure 4, being connected between the scraper 4 and inverse-U-shape rack 2 for inserting mode, splicing position is provided with
Linear springs 6；Alternatively, it as shown in figure 5, is connected between the scraper 4 and inverse-U-shape rack 2 for articulated manner, hinged place setting
There is torsionspring 7.
Preferably, the quantity of the nozzle is 5, is evenly distributed on the jet pipe 3.
Preferably, the roller group 5 has four rolling, is evenly distributed in the bottom outer wall of the strainer 1.
Embodiment described above only expresses the embodiment of the utility model, and description is more specific and detailed, but simultaneously
Cannot the limitation to the utility model patent range therefore be interpreted as, as long as the form institute using equivalent substitution or equivalent transformation
The technical solution of acquisition should all fall and be within the protection scope of the utility model.
