Abstract
The utility model relates to a heavy hammer type scraper device. The heavy hammer type scraper device comprises a scraper plate, a pressing plate, two scraper supports, a scraper bracket and a heavy hammer, wherein the two scraper supports are respectively fixed on a rack; the scraper bracket is connected between the two scraper supports; one end of the scraper bracket is connected with the heavy hammer through a threaded rod, and the other end of the scraper bracket is connected with the scraper plate; the scraper plate is connected with the pressing plate; the scraper supports are fixedly connected to the rack through bolts; the scraper plate is made from polypropylene or rigid polyethylene. When the heavy hammer type scraper device works, the pressing plate presses filter belts, and the distances between the scraper plate and the filter belts are 0.3-0.5 mm uniformly, so that the scraper plate is not in direct contact with the filter belts, and a filter cake also can be scraped, thus the service life of the filter belts can be prolonged; the scraper plate is formed by processing polypropylene or rigid polyethylene, so that the heavy hammer type scraper device has abrasion resistance and elasticity; the heavy hammer type scraper device is convenient to machine and maintain and low in machining cost.
Description
Technical field:
The utility model relates to belt vacuum filter doctor blade device field, relates in particular a kind of Weight type doctor blade device.
Background technology:
Belt vacuum filter is to take negative pressure of vacuum to realize the equipment of Separation of Solid and Liquid as motive force, structurally, filters section and arranges along the horizontal length direction, can complete continuously filtration, washs, blots, the operation such as strainer regeneration.Can be widely used in the Separation of Solid and Liquid in the fields such as metallurgy, mine, chemical industry, papermaking, food, pharmacy, environmental protection.Strainer breaks away from rubber strip together with the top filter cake blotted to be continued to move forward, when running to discharging wheel place, because its curvature becomes large, radius of curvature diminishes, make filter cake more easily peel off strainer, with sheet-type scraper or steel wire scraper, filter cake is peeled off to disposing again, but these two kinds of scrapers easily contact strainer, have reduced the service life of strainer.
The utility model content:
The purpose of this utility model is for the deficiencies in the prior art part, and a kind of Weight type doctor blade device is provided, and scrapes knife plate and does not directly contact strainer, can scrape and unload filter cake again, can extend like this strainer service life, and its processing is easy to maintenance, and processing cost is lower.
Technology solution of the present utility model is as follows:
A kind of Weight type doctor blade device comprises and scrapes knife plate, pressing plate, scraper bearing, scraper support and weight that described scraper bearing has two, is separately fixed on frame; Described scraper support is connected between two scraper bearings, and an end of scraper support connecting weight by screw rod, and the other end of scraper support is connecting scrapes knife plate; Described scraping on knife plate connecting pressing plate, and its pressing plate can be pushed down strainer and scrape knife plate equably apart from strainer 0.3 ~ 0.5mm.
As preferably, described scraper bearing is fixed on frame by bolt.
As preferably, described scraper sheet material matter is polypropylene or hard PEF.
The beneficial effects of the utility model are:
1, the utility model is scraped knife plate and is shaped with polypropylene or hard PEF, has wear-resisting, whippy advantage.
2, the utility model can be regulated the installation site on doctor blade device both sides, makes pressing plate push down strainer and scrapes knife plate equably apart from strainer 0.3-0.5mm, makes to scrape knife plate and does not directly contact strainer, can scrape and unload filter cake again, can extend like this strainer service life.
3, the counterweight pressure on the utility model both sides can be adjusted by adjusting lever, can eject when scraping knife plate with strainer lap-joint, and can rebound, and does not block strainer and is as the criterion.Can further extend like this strainer service life.
4, the processing of the utility model device is easy to maintenance, and processing cost is lower.
The accompanying drawing explanation:
Below in conjunction with accompanying drawing, the utility model is described further:
Fig. 1 is front view of the present utility model;
Fig. 2 is left view of the present utility model, and only draws half left view;
Fig. 3 is the front view of scraping knife plate of the present utility model;
The front view that Fig. 4 is scraper bearing of the present utility model;

In Fig. 1 ~ 8: 1-knife plate scraped; 2-pressing plate; 3-scraper bearing; 4-scraper support; 5-weight; 6-frame; 7-screw rod; 8-strainer.
The specific embodiment:
Embodiment, be shown in accompanying drawing 1 ~ 8, and a kind of Weight type doctor blade device comprises and scrapes knife plate 1, pressing plate 2, scraper bearing 3, scraper support 4 and weight 5, and described scraper sheet material matter is polypropylene or hard PEF, wear-resisting, high resilience; Described scraper bearing has two, and bolt is fixed on frame 6 respectively; Described scraper support is connected between two scraper bearings, and an end of scraper support connecting weight by screw rod 7, and the other end of scraper support is connecting scrapes knife plate; Described scraping on knife plate connecting pressing plate, and its pressing plate can be pushed down strainer 8 and scrape knife plate equably apart from strainer 0.3 ~ 0.5mm.
Above-described embodiment is the specific descriptions that the utility model is carried out; just the utility model is further described; can not be interpreted as the restriction to the utility model protection domain, within those skilled in the art makes some nonessential improvement according to the content of above-mentioned utility model and adjusts and all to fall into protection domain of the present utility model.
