Description

Filter cloth cleaning device

One, technical field

The present invention relates to a kind of filter cloth cleaning device, be suitable for the various solids and the band filter that separates of liquid, vertical plate and frame filter press, belong to the filter cloth cleaning device technical field.

Two, background technology

Band filter, vertical plate and frame filter press are to use in fields such as mine, chemical industry, food, environmental protection the filter plant to all kinds of material Separation of Solid and Liquid.Because in filter process, a part is thin, the clay material can be attached in the middle of filter cloth surface or the filter opening, after unsnatching filter cake, cleans by scraper etc., in this process, use the aqueduct shower nozzle spray, effect is general, especially fine granular materials can not come off fully, thereby stops up filter cloth and aqueduct shower nozzle, causes filter cloth filter efficiency attenuating in next cyclic process.Therefore must regularly shut down cleaning to filter cloth,, improve filter efficiency to guarantee the good air permeability of filter cloth.

Existing filter cloth cleaning device has following shortcoming:

, aqueduct shower nozzle complex structure higher to the rinse water water quality requirement stops up, needs regular dismounting to safeguard, increase maintenance cost and use cost easily.

The material thin for granularity, that viscosity is bigger stops up situations such as filter cloth, is difficult for cleaning up, and influences the equipment operating efficiency.

Stop up seriously as filter cloth, need regularly to shut down to clean, even and if the long-time filter cloth that stops up shut down and clean the result of use that also is difficult to recover filter cloth, change filter cloth thus and bring use cost to increase.

Three, summary of the invention

The objective of the invention is to overcome the problem that above-mentioned prior art exists, provide a kind of and can satisfy production requirement, but also can improve complete machine structure, reduce production and operation cost, prolong the filter cloth filter cloth cleaning device in service life.

Filter cloth cleaning device; comprise and clean bucket 3; clean in the bucket 3 and be provided with the changed course roller 4 that the filter cloth 2 by driven roller 1 interlock is led; filter cloth 2 is driven continuously indirectly or directly by driven roller 1 and rotates; 4 filter cloth guiding of changed course roller and supporting role; the plane of movement of corresponding filter cloth 2; be provided with ultrasonic cleaning equipment 5; brush roll 6; at least a cleaning device in the water washing device; brush roll 6 is by independent drive unit rotation; rely on the bristle on brush roll surface to wash attached to the material on filter cloth surface; the particle that ultrasonic cleaning equipment 5 relies on cavitation effect of ultrasonic waves will be blocked in the filter cloth smashes; flush out filter cloth through water again; thereby reach efficient; cleaning; the filter cloth regeneration purpose is cleaned 3 storages of bucket completely; effect such as prevent that liquid from spilling.

Water washing device has one at least at the positive and negative of filter cloth; The filter cloth water washing device has a water spray catch 7 to be fixed on the cleaning water pipe 8, has at least one clean-out opening 10 corresponding with it under each catch, and scavenge pipe one end is a movable drain plug 9;

Baffle plate can be circle, ellipse, rectangle, triangle, trapezoidal, polygon etc.; Baffle plate can be plane, curved face type etc.; Hole under the baffle plate at least one, the hole can be circle, ellipse, taper; The movable drain plug 9 of water pipe is movable dismountable.

Brush roll 6 can be arranged or do not have brush roll 6; Brush roll 6 is at the filtering surface of filter cloth, and bristle and filter cloth are tangent or crossing;

Ultrasonic cleaning equipment can be arranged or do not have ultrasonic cleaning equipment; A working face of ultrasonic cleaning equipment is parallel to filter cloth surface;

But ultrasonic cleaning equipment, brush roll, water washing device position independent assortment can freely be selected collocation;

The water of ejection presents fan-shaped.

Compared with prior art, filter cloth cleaning device of the present invention has following remarkable result:

Owing to use water injector of the present invention: clean water pipe, water spray catch and movable drain plug and form water washing device, not high to water quality requirement, be difficult for stopping up, easy to maintenance, make simple, with low cost;

Can use brush roll to force to scrub it is brushed for sticking material, solve sticking material and stop up filter cloth;

For the material particles that is blocked in the filter cloth, adopt ultrasonic cleaning equipment, need not often to shut down separately to use, increase operating efficiency, improve filter cloth service life;

These three kinds of cleaning ways all can work online, and promptly equipment need not to shut down the purpose that just can reach cleaning.

Filter cloth cleaning device of the present invention can improve the prior art problem from the design source, not only can satisfy production requirement, but also can improve complete machine structure, reduces production and operation cost, prolongs filter cloth service life.
