Abstract
The utility model discloses a scraper of a horizontal scraper centrifuge. The scraper comprises a scraper body and a scraper blade made of wear-resistant alloy, wherein the scraper blade is installed at the front end of the scraper body; and a detachable structure is adopted between the scraper body and the scraper blade. The worn scraper blade can be replaced while the whole scraper is not required to be replaced, so that the times for replacing the scraper can be reduced, the service life of the scraper is prolonged, and the using cost of the centrifuge is reduced; and moreover, the worn scraper blade is replaced in time, so that the production capacity of the centrifuge is improved.
Description
Technical field
The utility model relates to centrifuge machinery field, specifically is a kind of horizontal type scraper centrifuger scraper.
Background technology
Centrifuge is to utilize centrifugal force, the machinery of each component in separating liquid and solid particle or liquid and the mixtures of liquids.Centrifuge has a cylinder that rotates at a high speed around axis own, is called rotary drum, usually by Motor Drive.After separation of material adds rotary drum, rotated with speed by rapid the drive with rotary drum, each component is separated under centrifugal action, and discharges respectively.Usually, the rotary drum rotating speed is high more, and separating effect is also good more.Centrifuge is widely used in departments such as chemical industry, oil, food, pharmacy, ore dressing, coal, water treatment and boats and ships.
Scraper centrifugal machine mainly is made up of support, workspace location and power-section unit, the junction in workspace location and power-section unit, and main shaft drives the rotary drum running and realizes centrifugal action.During the centrifuge scraper, wing is slowly cut the rotary drum bed of material when rotary drum rotates, with material progressively scraping come off.Horizontal type scraper centrifuger is the perforated wall centrifuge of continuous running, intermittently operated, and its control mode is control automatically, also can manually control.Processes such as the charging in the centrifuge operating process, separation, washing, dehydration, discharging and filter cloth regeneration are generally all finished under full-speed state, and the single cycle time is short, and treating capacity is big, and can obtain dried filter residue and good clean result.
The doctor blade device of centrifuge is one of vitals of realizing the centrifuge full automatic working, the used scraper of horizontal type scraper centrifuger is worn in discharge process easily, and service life is short, changes frequent, maintenance cost is higher, makes the production capacity of centrifuge reduce and the use cost rising.
The utility model content
At the problem that prior art exists, the purpose of this utility model is to provide a kind of horizontal type scraper centrifuger scraper of changeable blade.
The utility model takes following technical scheme to realize:
A kind of horizontal type scraper centrifuger scraper, described scraper is made up of cutter hub and antifriction alloy blade two parts, and described blade is installed in the front end of cutter hub, is demountable structure between cutter hub and the blade.
Described cutter hub front end is provided with the open slot that blade is installed, and fixes by screw between described cutter hub and the blade.In the time of the tool changing sheet, become flexible screw, take out the blade of wearing and tearing, new blade is embedded in the open slot, tighten screw then and get final product.
Described cutter hub front end is provided with the open slot that blade is installed, and welding is fixing between described cutter hub and the blade.
Described cutter hub front end is provided with the open slot that blade is installed, and fixes by adhesive tape between described cutter hub and the blade.
The thickness of described blade is 2-5mm.
The height of described cutter hub is 3-4 a times of blade height.
Described blade is installed in the 1/4-1/3 place of cutter hub length, and the blade front end stretches out the cutter hub part.
The beneficial effects of the utility model are:
A kind of horizontal type scraper centrifuger scraper of the utility model, scraper is made up of cutter hub and antifriction alloy blade two parts, and blade is installed in the front end of cutter hub, is demountable structure between cutter hub and the blade.The blade of wearing and tearing can be changed, and will the scraper integral replacing, can reduce the replacing number of times of scraper like this, prolongs the service life of scraper, reduces the use cost of centrifuge simultaneously.In addition, in time change the blade of wearing and tearing, can improve the production capacity of centrifuge.
Description of drawings
Fig. 1 is by the fixing horizontal type scraper centrifuger blade construction schematic diagram of screw between cutter hub and the blade;
Fig. 2 is by the fixing horizontal type scraper centrifuger blade construction schematic diagram of welding between cutter hub and the blade;
Among the figure: 1-cutter hub, 2-blade, 3-screw, 4-weld.
The specific embodiment
Below by specific embodiment the utility model is described in further detail.
Shown in Figure 1 as Figure of description, a kind of horizontal type scraper centrifuger scraper of the utility model, scraper is made up of cutter hub 1 and antifriction alloy blade 2 two parts, and blade 2 is installed in cutter hub 1 front end, blade 2 front ends stretch out the cutter hub part, are demountable structure between cutter hub 1 and the blade 2.
The blade of wearing and tearing can be changed, and will the scraper integral replacing, can reduce the replacing number of times of scraper like this, prolongs the service life of scraper, reduces the use cost of centrifuge simultaneously.In addition, in time change the blade of wearing and tearing, can improve the production capacity of centrifuge.
Shown in Figure 2 as Figure of description, cutter hub 1 front end is provided with the open slot that blade 2 is installed, and is fixing in weld 4 welding between cutter hub 1 and the blade 2.
The thickness of blade is 2mm, the height of cutter hub is 3 times of blade height, blade is installed in 1/4 place of cutter hub length, the blade front end stretches out the cutter hub part, the length of blade is 1/4 of cutter hub length approximately, this shows that the used material of manufacturing blade lacks a lot than all materials of the whole scraper of manufacturing, so change this mode of the blade environmental protection more economically of wearing and tearing.
All the other are with embodiment 1.
