The specific dimensions used in this embodiment are merely for illustrative purposes and do not limit the scope of protection of the present invention.

[0031] like Figure 1-5 As shown, an automatic slag flushing system for iron oxide on a hot delivery roller table for large square billets includes a slag flushing trough 2 arranged along a hot delivery roller table body 1, a water pipe 3 installed on the slag flushing trough 2, a high-pressure water pump 4 installed at the end of the water pipe 3, a plurality of evenly distributed branch pipes 5 connected to the water pipe 3, and a high-pressure nozzle 6 provided at the output end of the branch pipe 5. The high-pressure water pump 4 pumps water and pressurizes it, and then transmits it through the water pipe 3 and the branch pipe 5. The water is sprayed from the high-pressure nozzle 6 to wash the inner wall of the slag flushing trough 2, and the iron oxide falling into the slag flushing trough 2 is directionally transported for centralized treatment;

[0032] A guide mechanism 7 is provided on the hot delivery roller body 1 and on both sides of each rotating roller to guide the iron oxide to fall into the slag flushing trough 2. The wind generated by the air pump 8 blows on the surface of the guide mechanism 7 to facilitate the shedding and transportation of the iron oxide.

[0033] As an embodiment of the guiding mechanism 7 in the present invention:

[0034] The guiding mechanism 7 includes a feeding inclined plate 71, the bottom end of which extends to above the slag flushing trough 2. A plurality of chutes are provided on the upper surface of the feeding inclined plate 71, and the chutes are located between two adjacent rotating rollers. The chutes limit the movement range of the iron oxide to prevent the iron oxide from falling into the gap of the equipment and causing problems such as being unable to be cleaned.

[0035] Specifically, the chute is composed of two convex plates 72 fixed on the feed inclined plate 71, and the two convex plates 72 are distributed in an inverted eight shape to facilitate the guidance of the iron oxide.

[0036] Specifically, a channel hole 73 is opened on the side wall of the hot delivery roller body 1 close to the slag flushing trough 2, and the chute passes through the channel hole 73, directly guiding the iron oxide to fall to the top of the slag flushing trough 2, avoiding the iron oxide from getting stuck or falling outside the slag flushing trough 2.

[0037] Specifically, multiple groups of guide plates 74 are installed between the two side walls of the hot delivery roller body 1, the number of guide plates 74 in each group is set to two, and the two guide plates 74 in the same group are symmetrically distributed on both sides of the rotating roller; a gap is reserved between the top of the guide plate 74 and the rotating roller, and the bottom of the guide plate 74 is located above the chute, so that the detached iron oxide is guided into the chute area without hindering the operation of the rotating roller.

[0038] Specifically, a cover plate is buckled on the top of the slag flushing trough 2, and the cover plate is made of a transparent plastic material to avoid splashing of flushing water and does not affect the observation of the distribution of iron oxide in the slag flushing trough 2.

[0039] Specifically, an air pump 8 is installed on the side of the hot delivery roller body 1, and the output end of the air pump 8 sends air to the side of the chute through a pipe and an exhaust hood, which is used to blow the iron oxide toward the slag trough 2 to avoid the problem of material adhesion and accumulation.

[0040] The automatic iron oxide slag flushing system also includes an electrical control box 9 for controlling the start / stop of the air pump 8 and the high-pressure water pump 4.

[0041] When the utility model is used, the manual control mode and the automatic intelligent mode can be selected through the electrical control box 9;

[0042] The iron oxide automatic slag flushing system is under manual control mode, and the boiler operator conducts periodic inspections, such as once every 0.5-1 hours, to check whether there is any blockage in the slag flushing trough 2. If any foreign matter falls into it, it will be cleaned in time to avoid blockage of the slag flushing trough 2. When flushing and cleaning is required, the high-pressure water pump 4 is controlled by the electrical control box 9 to work, and the principle of no confirmation and no operation is followed;

[0043] When selecting the automated intelligent mode, the system's control components and their coordination are as follows:

[0044] A processor 91 is installed inside the electrical control box 9, and the output end and output end of the processor 91 are respectively provided with an A / D converter and a D / A converter. The connection between the shunt pipe 5 and the water pipe 3 is provided with an electromagnetic control valve 10, and the high-pressure water pump 4, the air pump 8 and the electromagnetic control valve 10 are all electrically connected to the D / A converter. The connection end of the processor 91 is electrically connected to a timer 92. A camera 11 electrically connected to the A / D converter is provided on the top of the hot delivery roller body 1. The monitoring data is transmitted to the processor 91 and is timed by the timer 92. For example, 0.5 hours is a week, and the number of times a week is reached. When the iron oxide is blocked in the chute, the air pump 8 and the high-pressure water pump 4 are automatically switched on and off. According to the distribution of the iron oxide in the slag trough 2, the opening degree of the plurality of electromagnetic control valves 10 is controlled to increase the water pressure at the accumulation location of the iron oxide, thereby facilitating the discharge of the iron oxide from the slag trough 2.

[0045] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It is apparent to those skilled in the art that various changes, modifications, substitutions, and variations to these embodiments may be made without departing from the principles and spirit of the present invention, and these changes and modifications still fall within the scope of protection of the present invention.
