Technical field
the utility model relates to a kind of centrifuge with cutter discharge of solid, is specifically related to a kind of centrifuge with cutter discharge of solid with scraping cutter bar sheath.
Background technology
centrifuge is that the centrifugal inertial force that utilizes drum rotating to produce is realized the separation of suspension, emulsion and other heterogeneous material or concentrated machine.
according to solid phase discharge way difference, centrifuge can be divided into gravity dumping, artificial top discharging, manually descend the types such as discharging, centrifugal discharge, scraper discharging, vacuum intake and screw unloading.
scraper discharging formula centrifuge is mainly made up of parts such as high-revolving rotary drum, transmission device and discharge device for scrapers, operation principle is: the suspension separating when needs enters after bowl, the rotary drum of High Rotation Speed produces powerful centrifugal force solid phase particles is deposited to drum inner wall, and be trapped in rotary drum by filter screen, liquid phase leaches by filter screen, and the solid phase that is trapped in drum inner wall is scraped and discharged rotary drum by scraper.
in actual production; due to the characteristic difference of various materials; there are a lot of materials to there is very serious corrosivity; so very important to the protection of doctor blade device; due within scraping cutter bar is positioned at centrifuge workspace; contact with material at any time, so each centrifuge with cutter discharge of solid all will be in the face of the protection question of scraping cutter bar.
common scraping cutter bar sheath is to be made up of the flexible material such as rubber, plastics, adopt cartridge type accordion structure, can carry out up-down stretch and directional-rotation action, defect be the solid-phase material that splashes fall folding Zhe upper after, cannot remove in time, solidify quantity and cause after many damage of sheath.
Summary of the invention
technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, a kind of scraping cutter bar sheath for centrifuge with cutter discharge of solid is provided, by many groups sliding sleeve isolation rotary drum internal work district and scraper drive area, do not make the material in the grease contaminated rotary drum of scraper workspace, isolate the corrosion of material to scraping cutter bar simultaneously.
for solving above technical problem, the utility model is taked following technical scheme:
a kind of centrifuge with cutter discharge of solid with scraping cutter bar sheath, comprise and be fixed on scraping girff, be installed on the scraper base scraped on girff, be arranged on scraper base and the scraping cutter bar that can stretch and rotate, be fixedly connected on the scraper of scraping cutter bar end and be arranged on to scrape and drive the driving mechanism that scraping cutter bar is flexible and rotate on girff of centrifuge casing top, scraping cutter bar is also provided with scraping cutter bar sheath outward, scraping cutter bar sheath comprises many group sliding sleeves, between sliding sleeve and sliding sleeve, be mutually slidably socketed, between sliding sleeve and sliding sleeve, be provided with sealing ring.
preferably, in sealing ring and between sliding sleeve, be also provided with dirt-proof boot.
preferably, the external diameter of organizing sliding sleeve reduces successively.
preferably, the material of sliding sleeve is metal.
further preferably, the material of sliding sleeve is stainless steel or titanium alloy.
preferably, driving mechanism comprises rotary oil cylinder and hoist cylinder.
preferably, scraping cutter bar sheath one end is connected with described scraper base, and the other end is connected with described scraper.
the utility model compared with prior art tool has the following advantages:
the utility model adopts extension type multiple tube-in-tube structure, and isolation rotary drum internal work district and scraper drive area do not make the material in the grease contaminated rotary drum of scraper workspace, isolate the corrosion of material to scraping cutter bar simultaneously; In the time of scraper axially-movable, while stretching out, can protect scraping cutter bar; Can be by under the material scraper outside cover when retraction; When rotation, be not subject to the restriction of the anglec of rotation, can rotate to any angle; Owing to there being sealing ring between sleeve, can protect the etch of corrosive gas to scraping cutter bar simultaneously.
