Abstract
The utility model discloses a graphite carbon brick cleaning scraping knife. The graphite carbon brick cleaning scraping knife comprises a cylindrical knife handle, a rectangular stainless steel sheet and a trapezoid blade. The cylindrical knife handle is vertically fixed in the middle of the stainless steel sheet, the trapezoid blade is fixed at one end of the stainless steel sheet, and knife edges are arranged on three faces of the other end of the stainless steel sheet. The graphite carbon brick cleaning scraping knife is T-shaped in appearance and simple in structure, the shape and the edge directions are matched with the shape in grooves of carbon bricks in an ingot furnace thermal field, therefore impurities in the grooves of the carbon bricks can be cleaned conveniently in a narrow top space in a furnace chamber, and manufacturing cost is low. The graphite carbon brick cleaning scraping knife is multifunctional, impurities on common planes can be cleaned conveniently through the trapezoid blade, and the grooves and stepped areas can be cleaned conveniently through the knife edges on the three faces of one end of the stainless steel sheet. By means of the graphite carbon brick cleaning scraping knife, the carbon bricks can be cleaned effectively, impurity removal effects for the top of the ingot furnace thermal field are guaranteed, and therefore quality of silicon ingots is guaranteed.
Description
Technical field
The utility model relates to a kind of graphite carbon brick cleaning scraper.
Background technology
Ingot furnace thermal field top has eight in order to control the carbon brick of exhaust, long-time exhaust, impurities removal cause impurities accumulation, the slit diminishes, the impurities removal effect reduces, influence the silicon ingot quality, therefore need to use the scraper periodic cleaning, because it is furnace chamber inner top space is narrow and small, very difficult and cleaning is unclean during cleaning in the carbon brick groove.
Scraper claims trowel again, repaiies and uses the widest instrument at most in the type, has tack, tip and round end etc. several, be mainly used to repair the big plane of molding sand (core), excavation dead head, cutting groove and casting rib, finishing sand base and soft or hard casting bed lift the strengthening nail on sand mold surface into sand mold etc.
Existing blade geometry does not conform to the interior shape of the interior carbon brick groove of ingot furnace thermal field with the direction of putting the first edge on a knife or a pair of scissors, because shape in its ingot furnace thermal field carbon brick groove is to be exhaust, impurities removal design, so the shape of existing scraper and the place of putting the first edge on a knife or a pair of scissors are not suitable for the cleaning of impurity in the groove, and existing blade geometry and size can not be fit to clear up thermal field carbon brick and the interior impurity of groove.
The utility model content
The technical problems to be solved in the utility model provides a kind of graphite carbon brick cleaning scraper, profile is T type scraper, simple in structure, shape conforms to the interior shape of carbon brick groove in the ingot furnace thermal field with the blade direction, convenient impurity in narrow and small furnace chamber inner top space cleaning carbon brick groove, cost of manufacture is low; This scraper function is many, the impurity on the trapezoidal blade easy cleaning common plane, three blade easy cleaning grooves of stainless steel substrates one end and step zone; This scraper can effectively be cleared up carbon brick, has guaranteed the impurities removal effect at ingot furnace thermal field top, thereby has guaranteed the silicon ingot quality.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of graphite carbon brick cleaning scraper comprises cylinder handle of a knife, rectangle stainless steel substrates and trapezoidal blade; Cylinder handle of a knife vertical fixing is in the centre of stainless steel substrates, and trapezoidal blade is fixed in an end of stainless steel substrates, and the other end three faces of stainless steel substrates have blade.
The dismountable end that is fixed in described stainless steel substrates of trapezoidal blade.
Handle of a knife is stainless steel tubulose handle of a knife.
Handle of a knife is telescopic joint stainless steel handle of a knife.
The beneficial effect that adopts technique scheme to produce is: the utility model graphite carbon brick cleaning scraper profile is T type scraper, simple in structure, shape conforms to the interior shape of carbon brick groove in the ingot furnace thermal field with the blade direction, convenient impurity in narrow and small furnace chamber inner top space cleaning carbon brick groove, cost of manufacture is low; This scraper function is many, the impurity on the trapezoidal blade easy cleaning common plane, three blade easy cleaning grooves of stainless steel substrates one end and step zone; This scraper can effectively be cleared up carbon brick, has guaranteed the impurities removal effect at ingot furnace thermal field top, thereby has guaranteed the silicon ingot quality.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is vertical view of the present utility model;
Fig. 2 is front view of the present utility model;
1 is the cylinder handle of a knife, and 2 is the rectangle stainless steel substrates, and 3 is trapezoidal blade, and 4 is blade.
The specific embodiment
A kind of graphite carbon brick cleaning scraper comprises cylinder handle of a knife 1, rectangle stainless steel substrates 2 and trapezoidal blade 3; Cylinder handle of a knife 1 vertical fixing is in the centre of stainless steel substrates 2, and trapezoidal blade 3 is fixed in an end of stainless steel substrates 2, and the other end three faces of stainless steel substrates 2 have blade 4;
Trapezoidal blade 3 dismountable ends that are fixed in stainless steel substrates 2;
Handle of a knife 1 can be stainless steel tube shape handle of a knife;
Handle of a knife can save the stainless steel handle of a knife for telescopic, regulates the length of handle of a knife as required.Because T shape scraper is inconvenient to place and transport, therefore can be set to detachable by handle of a knife as distortion of the present utility model, handle of a knife is threaded with stainless steel substrates, when needing to use handle of a knife is installed, detachably get off when not needing to use, when handle of a knife and stainless steel substrates adopt when being threaded, can suitably increase the thickness of junction stainless steel substrates.For the frictional force that increases the stainless steel handle of a knife when avoiding using because slipping out of the hand of causing of stainless smooth surface damaged the scraper accident, one deck skid resistant course can be set, such as plastics, layer of silica gel or the heat insulation foam layer etc. that have projection in the outside of handle of a knife.
The length of preferred stainless steel substrates is 130mm, wide 30mm, thick 2.5～3mm, the radius of cylinder handle of a knife is 12.5mm, the length of cylinder handle of a knife is 80mm, and the upper base of trapezoidal blade is identical with the width of stainless steel substrates, and the length of going to the bottom is 50mm, trapezoidal blade is fixed in an end of stainless steel substrates by bolt and nut, trapezoidal blade can be disassembled when not using.
When needs cleanings stepped area, use the end with three blades, the cross section of each stepped area is L shaped, and the wherein two sides of three blades is contacted with the both sides of L, level spurs the scraper handle of a knife can clear up stepped area easily; When needs cleaning normal areas, can use trapezoidal scraper.
