Abstract
The utility model relates to a highly-efficient slag-dragging harrow, comprising two slag harrow shafts (1) and two slag harrows having a vertical plate (3) and fixed on the lower part of two slag harrow shafts (1), a compressed gas blowing pipe (2) mounted on the vertical plate (3) or a transmission box, a compressed gas pipe connected to the upper part of the compressed gas blowing pipe (2), and a gas orifice arranged in the lower part of the compressed gas blowing pipe (2). While the slag harrow drags the slag rotatably, the compressed gas is injected from the blowing pipe to blow off the slag on the back of the slag harrow and the edge of the ladle wall, the slag is clamped and dragged by the slag harrow, accordingly, the slag dragging efficiency is improved considerably.
Description
Technical field the utility model relates to a kind of slag rake of swinging dragveyer.Described swinging dragveyer is a kind of special equipment that is used to clear up ladle (jar) liquid level scum silica frost.
The same applicant of background technology present patent application has proposed the utility application that name is called " a kind of molten iron drags for the special-purpose slag rake of slag " on January 10th, 2005 to Patent Office of the People's Republic of China, and application number is 200520000290.6.The special-purpose slag rake of this patent application formerly comprises slag harrow shaft and the riser that is fixed in the slag harrow shaft lower end, is connected with base plate in the riser lower end, is connected with front end-plate and end plate respectively in the rear and front end of base plate.Riser, end plate, base plate are formed the container of a two sides opening, are used for storing left and right sides slag rake and drag for the slag process in revolution and drive the bits that flock together.It is big to have the slag capacity, the characteristics that scarfing cinder efficient is high.
The applicant finds in practice, in dragging for the slag process, because the slag harrow shaft that is used to connect transmission case and slag rake is in the center of ladle (jar) all the time, the zone that the revolution of slag rake is covered is changeless, slag is harrowed the Zone Full that revolution can not cover the molten iron liquid level, drags for the slag dead band thereby harrow the end generation with slag below two slags rake base plate.What solve the current practice of dragging for slag in the dead band and be conversion slag rake drags for the slag original position, by twice even repeatedly drag for the purpose that slag reaches basic elimination dead band.But do like this and influenced the operating efficiency of dragging for slag.
Utility model content technical problem to be solved in the utility model provides a kind of new efficient slag rake, drags for the slag dead band in order to elimination, improves and drags for slag efficient, overcomes the deficiency of above-mentioned patent application formerly.
In order to address the above problem, the utility model has adopted following technical scheme.
A kind of efficient slag rake mainly comprises two slag harrow shafts and two the slags rakes that include riser that are individually fixed in two slag harrow shaft lower ends, and the upper end of two slag harrow shafts all is connected with transmission case, it is characterized in that: be provided with Compressed Gas winding-up pipe between two slags rakes.
Described Compressed Gas winding-up pipe can be for L shaped, and quantity is one or only measures that it is fixed therein on the riser or is separately fixed on two risers; This winding-up pipe upper end connects compressed gas tube, offers several fumaroles on the horizontal segment of lower end.
The compressed gas tube that winding-up pipe upper end connects can be connected by the compressed gas source of pipeline with the transmission case outside, also can be connected with the slag harrow shaft of hollow, and slag harrow shaft is connected with the compressed gas source of transmission case outside.
Described fumarole is opened in the bottom surface and the pipe end face of winding-up pipe horizontal segment.
Described Compressed Gas winding-up pipe also can the upper end be fixed on the transmission case and by the compressed gas source of pipeline with the transmission case outside and be connected, lower ending opening or offer venthole.
Adopt the technical program when slag is dragged in the revolution of slag rake, Compressed Gas sprays from the winding-up pipe, with ladle (jar) liquid level dead band slag, it is the slag of the slag rake back side and bag (jar) the mural margin dead band of blowing off, be compressed gas and blow and catch up with, or driven, dragging for the slag later stage by the slag rake, these slags will can be pulled out dragging in the slag scope that slag is harrowed.Therefore improved and dragged for slag efficient, reduced and dragged for the slag time.
Description of drawings Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of the utility model winding-up pipe.
The specific embodiment as shown in Figure 1, 2, in embodiment of the present utility model, riser 3 is fixed in the lower end of slag harrow shaft 1, and can rotate with the latter, drives the revolution of whole slag rake.Be connected with base plate in riser 3 lower ends, be connected with front end-plate and end plate respectively in the rear and front end of base plate.
Also be provided with L shaped Compressed Gas winding-up pipe 2, it is fixed on the described riser 3, and rotates with the slag rake.This winding-up pipe is positioned at above the molten iron liquid level when guaranteeing that slag is dragged in slag rake revolution, and its lower end horizontal segment should be apart from the suitable distance in the lower surface of riser 3, such as the 50-500 millimeter.
These winding-up pipe 2 upper ends connect compressed gas tube, and compressed air can pass to compressed gas tube by the slag harrow shaft of hollow from transmission case, also can pass to compressed gas tube from the transmission case outside by pipeline.Offer several fumaroles on the winding-up pipe 2 lower end horizontal segments.Described fumarole is opened in the bottom surface and the pipe end face of winding-up pipe 2 horizontal segments.
A L shaped Compressed Gas winding-up pipe 2 also can only be set, and it is fixed therein on the arbitrary riser 3.
One or two Compressed Gas winding-up pipes that do not rotate with the slag rake also can be set, and it can be fixed on the transmission case.
