The technical scheme of the utility model is that:
the utility model provides a jar structure of ventilating of fritting furnace, includes the main tank body, with the gas input hose and the gas output hose of the main tank body intercommunication, its technical essential is: the utility model discloses a water injection tank, including the main jar of body, the main jar of body top support has the water injection jar body in advance, be equipped with the water injection pipeline between the bottom of the water injection jar body in advance and the top surface of the main jar of body, be equipped with water injection control valve on the water injection pipeline, water injection jar body top is equipped with the water filling port in advance, be equipped with level sensor in the water injection jar body in advance and the main jar body respectively.
In the aeration tank structure of the sintering furnace, one end of the gas input hose inserted into the main tank body is connected with the dispersed gas joint, the dispersed gas joint is inserted below the liquid level, the tail end of the dispersed gas joint is in a bell mouth shape, the center of the port of the dispersed gas joint is provided with the gas distribution cone extending into the gas input hose side, and a plurality of connecting ribs are arranged between the lower surface of the gas distribution cone and the edge of the port of the dispersed gas joint. The gas distribution cone is favorable for scattering core gas clusters of input gas, so that the input gas is dispersed into liquid to be thoroughly purified.
According to the ventilating tank structure of the sintering furnace, one end, inserted into the main tank body, of the gas output hose is connected with the gas introducing joint, the gas introducing joint is located above the liquid level, and the tail end of the gas introducing joint is in a horn mouth shape.
The utility model has the advantages that:
1. through addding the water injection jar body in advance, earlier to the water injection jar body water injection in advance, again by the water injection jar body in advance to the water injection of main jar of body water injection, save the step of the people for holding between the fingers gas transmission hose, when to the water injection jar body water injection in advance, water injection control valve closes, the gas that does not influence the main jar of body gets into the fritting furnace, gaseous uninterrupted gas conveying is continuous, when opening water injection control valve, the water filling port of the water injection jar body in advance is closed all the time, external gas can't get into, thereby guarantee that the sintering gas is pure all the time, to sum up, guarantee the continuity and the purity of sintering gas.
2. The whole process does not need to pinch the gas transmission hose, and the operation can be carried out by a single person, so that the manual labor is saved, and the operation is simple and safe.

In the figure: 1. the device comprises a pre-injection water tank body, 2 water injection pipelines, 3 water injection control valves, 4 gas input hoses, 5 a main tank body, 6 a sintering furnace, 7 gas output hoses, 8 water injection ports, 9 dispersed gas joints, 10 gas distribution cones, 11 connecting ribs and 12 gas guide joints.
Detailed Description
As shown in fig. 1 to 4, the aeration tank structure of the sintering furnace comprises a main tank 5, a gas input hose 4 and a gas output hose 7 which are communicated with the main tank 5.
The water injection device is characterized in that a pre-injection water tank body 1 is additionally supported at the top of the main tank body 5, a water injection pipeline 2 is arranged between the bottom of the pre-injection water tank body 1 and the top surface of the main tank body 5, a water injection control valve 3 is arranged on the water injection pipeline 2, and a water injection port 8 is arranged at the top of the pre-injection water tank body 1. Liquid level sensors (omitted in the figure) are respectively arranged in the pre-injection tank body 1 and the main tank body 5. When the liquid in the main tank body 5 is reduced to a set lower limit, a worker opens the water injection control valve 3 according to a signal instruction, and water injected in advance in the pre-injection tank body 1 is injected into the main tank body 5; when the liquid in the water pre-injection tank body 1 is reduced to a set lower limit, a worker opens the water injection port 8 according to a signal instruction, water is injected into the water pre-injection tank body 1, and external gas is prevented from entering the main tank body 5 through the water pre-injection tank body 1.
