Description
Technical field
The utility model belongs to metallurgical technology field, and in particular to a kind of filter press material-clearing device.
Background technique
Currently, the main filtration equipment for mining and metallurgy production has: disc vacuum filter, chamber-type press filter, horizontal belt
Filter, vertical type blotter press etc..In recent years, vertical type blotter press with its high operating efficiency, to thin and viscous material is good scrapes filter
Effect and be widely used.
As country is increasingly stringenter environmental requirement, Industrial Wastewater Treatment amount increasingly increases, and vertical type blotter press application is more
It is widely to be promoted.But industrial wastewater is different from ore pulp, for its complicated composition, need to add the solidifying conjunction of a large amount of flocculants,
As a result filter press discharging material viscosity is caused to increase, material viscosity is larger after filters pressing can not fall off naturally with filter cloth bonding, need to borrow
Drainage cloth scraper carries out scraper.
And filter cloth scraper in the prior art glues the thickness of glutinous accumulation according to material when carrying out scraper operation on filter cloth
Degree needs closed-down manual to adjust the spacing between scraper and filter cloth cloth cover, heavy workload, and manually adjust it is difficult to ensure that scraper with
Spacing between filter cloth cloth cover is consistent, causes on filter cloth remaining material excessive or scraper scratches filter cloth.Remaining material mistake
When more, the shutdown of high frequency time is needed to carry out artificial cleaning filter cloth, production efficiency is low.
Utility model content
The purpose of this utility model is to provide a kind of filter press material-clearing devices, guarantee filter press in non-stop-machine situation
Realize that the spacing between scraper and the cloth cover of filter cloth automatically adjusts.
In order to achieve the above technical purposes, the utility model uses a kind of following technical scheme: filter press material-clearing device, packet
The knife rest of scraper and fixed doctor is included, knife rest is hingedly arranged on the rack by articulated shaft, the resultant force phase of the gravity of scraper and knife rest
The blade of scraper is driven to recline to the cloth cover of filter cloth the rotating torque of articulated shaft, the width direction and filter cloth of the blade of scraper
Direction of travel in angle formula arrange.
In above-mentioned technical proposal, the resultant force of the gravity of scraper and knife rest makes the knife of scraper relative to the rotating torque of articulated shaft
Sword concordantly sticks on filter cloth cloth cover, guarantees filter press between realizing between scraper and the cloth cover of filter cloth in non-stop-machine situation
Away from automatic adjustment, and the material on the cloth cover of effectively cleaning filter cloth, improve production efficiency.

Specific embodiment
The utility model is described in detail below in conjunction with attached drawing.
A kind of filter press material-clearing device, including scraper 10 and the knife rest of fixed doctor 10 20, knife rest 20 is cut with scissors by articulated shaft 40
It connects and is arranged in rack 30, the resultant force of the gravity of scraper 10 and knife rest 20 drives scraper 10 relative to the rotating torque of articulated shaft 40
Blade concordantly recline to the cloth cover of filter cloth 50, the direction of travel of the length direction of the blade of scraper 10 and filter cloth 50 is in angle formula
Arrangement.The resultant force of the gravity of scraper 10 and knife rest 20 makes the blade of scraper 10 concordantly recline relative to the rotating torque of articulated shaft 40
On the cloth cover of filter cloth 50, the length direction of the blade of scraper 10 and the direction of travel of filter cloth 50 are arranged in angle formula, are needed herein
Since the thing to be illustrated be the distance on the width i.e. blade of the blade of scraper 10 having blade position to the edge of a knife, guarantees filter press
The spacing automatic adjustment between scraper 10 and 50 cloth cover of filter cloth is being realized in non-stop-machine situation, and effectively clears up the cloth of filter cloth 50
Material on face improves production efficiency.
Preferably, knife rest 20 includes two rod pieces, and the both ends for constituting the rod piece of knife rest 20 are hingedly arranged by articulated shaft 40 to exist
In rack 30, the blade of scraper 10 is directed toward to be arranged with the cloth cover of filter cloth 50 formula angle at an acute angle.The blade of scraper 10 is directed toward and filter
The cloth cover of cloth 50 formula angle arrangement at an acute angle easily facilitates scraper 10 and scrapes off the viscous glutinous material in 50 surface of filter cloth, reaches good
Cleaning effect.
As shown in Figure 4,5, it is preferred that knife rest 20 includes the swing arm 22 at 21 both ends of angle steel bar 21 and angle steel bar, swing arm 22
Upper end is hingedly arranged in rack 30 by articulated shaft 40, and the knife plate face of scraper 10 and the front side board of angle steel bar 21 constitute detachable and connect
It connects.The knife plate face of scraper 10 and the front side board of angle steel bar 21 are detachably connected with by screw or bolt composition, when the knife of scraper 10
When sword is seriously worn because the cloth cover of long-time and filter cloth 50 scrapes, it is conveniently replaceable scraper 10, in addition the knife edge part of scraper 10 is adopted
Cloth cover is scratched when being scraped with the cloth cover of engineering plastics material, the blade and filter cloth 50 that prevent scraper 10, influences the filters pressing of filter cloth 50
Effect.Knife rest 20 is using the steel that corrosion resistance is strong and rigidity is good, such as 00Cr17Ni14Mo2 etc..
As shown in Figure 2,3, it is preferred that articulated shaft 40 closes on the blanking end reversing roller 51 of filter cloth 50 and is arranged in rack 30
On, the axial direction of articulated shaft 40 is parallel with the cloth cover of filter cloth 50.Such setting, when the blade of scraper 10 scrapes the cloth cover of filter cloth 50
When clearing up material, because articulated shaft 40 closes on the blanking end reversing roller 51 of filter cloth 50, i.e. scraper 10 on knife rest 20 also closes on commutation
Roller 51 can guarantee that the active force between the blade of scraper 10 and the cloth cover of filter cloth 50 is appropriate, and both effectively cleaning 50 surface of filter cloth was viscous
Glutinous material, and the cloth cover of filter cloth 50 can not be scratched.
Preferably, the distance of back side panel of the edge of a knife of scraper 10 to angle steel bar 21 is greater than the back side panel of angle steel bar 21 to filter cloth
The distance of 50 cloth cover.Such setting, be further ensured that the scraper 10 on knife rest 20 blade be directed toward always with filter cloth 50
Cloth cover formula angle arrangement at an acute angle, scrapes off 50 surface of filter cloth convenient for scraper 10 and glues glutinous material.
