Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-4The utility model provides a technical solution: a charging device for a cupola furnace, comprising: a furnace body 1, two feeding pipes 2 are fixedly connected to the outer surface of the furnace body 1, a rotating shaft 3 and a rotating shaft 4 are movably embedded in the inner surfaces of the two feeding pipes 2, two swing rods 5 are fixedly installed on the outer surfaces of the two rotating shafts 3, and a plurality of swing rods 5 are fixedly connected to the outer surfaces of the counterweights 7, two swing rods 6 are fixedly installed on the outer surfaces of the two rotating shafts 4, and a plurality of swing rods 6 are fixedly connected to the outer surfaces of the counterweights 8, the two feeding pipes 2 Two motors 11 are arranged on the outer surface of each of the plurality of motors 11, a rotating shaft 3 10 is arranged through the output shaft, a cam 9 is fixedly installed on the outer surface of each of the plurality of rotating shafts 3, a baffle 13 is fixedly installed on the outer surface of each of the two rotating shafts 13, a baffle 2 14 is fixedly installed on the outer surface of each of the two rotating shafts 2 4, so as to avoid the situation in which the furnace body 1 is connected with the external space during feeding, causing heat leakage, thereby improving the efficiency of the blast furnace, reducing energy consumption, preventing heat from diffusing to the outside, and protecting the working environment of employees.

[0023] like Figure 1-4 As shown, the inner surfaces of the two feed pipes 2 are movably embedded with multiple rotating rods 15, and the multiple rotating rods 15 are fixedly installed with multiple crushing wheels 16 on one side close to the inside of the two feed pipes 2, and the multiple rotating rods 15 are fixedly installed with multiple pulleys 17 on one side close to the outside of the two feed pipes 2, and the outer surfaces of the multiple pulleys 17 are transmission-connected with transmission belts 18, wherein the outer surfaces of the two rotating rods 15 are fixedly installed with motors 19, and the outer surfaces of the two feed pipes 2 are provided with multiple rappers 20, and the outer surfaces of the multiple rappers 20 are fixedly connected with transfer rods 12, and the multiple transfer rods 12 are evenly divided into two groups, and the outer surfaces of the two groups of transfer rods 12 are fixedly connected with filter plates 21, so as to avoid the situation that the raw materials are too large and the internal raw materials cannot be completely burned, thereby improving the utilization rate of energy and reducing the production cost.

[0024] like Figure 1-4 As shown, the two baffles 13 and 14 are movably embedded in the inner surfaces of the two feeding pipes 2. The switching of the baffles 13 and 14 can prevent the furnace body 1 from directly contacting the outside world and avoid the leakage of heat energy.

[0025] like Figure 1-4 As shown, two filter plates 21 are arranged on the inner surfaces of the two feed pipes 2. The filter plates 21 can screen the fuel that meets the requirements and continue to crush the fuel that does not meet the requirements, thereby improving the utilization rate of the fuel.

[0026] Working principle: This equipment is a feeding device for a cupola. When in use, the raw materials are introduced into the two feeding pipes 2 on the furnace body 1, and the two motors 2 19 are started. The two motors 2 19 drive two of the rotating rods 15 to rotate through the output shaft. The two rotating rods 15 cooperate with the pulley 17 and the transmission belt 18 to make multiple rotating rods 15 rotate synchronously. The multiple rotating rods 15 drive the crushing wheels 16 to rotate. The multiple crushing wheels 16 crush the raw materials in the feeding pipe 2. The crushed raw materials will pass through the filter plate 21 and fall onto the two baffles 2 14, while the raw materials that cannot pass through the filter plate 21 will continue to be crushed. The multiple vibrators 20 drive the two filter plates 21 to vibrate through the multiple transfer rods 12, so that the filter plates 21 have self-cleaning ability. When the crushed raw materials fall onto the two baffles 2 14, the multiple motors 1 11 are started. The multiple motors 1 11 drive the multiple rotating shafts 3 10 to rotate through the output shaft. The multiple rotating shafts 3 10 drive the multiple cams 9 to rotate. The multiple cams 9 first squeeze the multiple rocker rods 2 6, so that the multiple rocker rods 2 6 drive the two baffles 2 14 to rotate through the two rotating shafts 2 4, so that the raw materials on the baffle 2 14 fall onto the baffle 1 13, and then as the multiple cams 9 continue to rotate, the multiple cams 9 no longer drive the rocker rods 2 6 to rotate. At this time, the multiple counterweights 2 8 will use their own weight to pull the multiple rocker rods 2 6 to rotate in the opposite direction. The multiple rocker rods 2 6 use the two rotating shafts 2 4 to drive the two baffles 2 14 to rotate in the opposite direction, so that the baffle 2 14 is horizontal and closed. When the multiple cams 9 squeeze the multiple rocker rods 1 5, the multiple rocker rods 1 5 will drive the two baffles 13 to rotate through the two rotating shafts 1 3, and the two baffles 13 will change from a horizontally closed state to a vertically opened state. At this time, the raw materials will leave the baffle 2 14 and enter the furnace body 1 for combustion. The counterweight 1 7 can use its own weight to indirectly close the baffle 13.

[0027] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
