Description

Technical Field

[0001] The utility model relates to the technical field of furnace front opening machines, in particular to a furnace front opening machine equipped with an atomizing spray device. Background Art

[0002] The blast furnace is an important metallurgical equipment used to convert iron ore and other raw materials into molten iron. The slag inside the blast furnace is produced by impurities and chemical reactions in the ore. The blast furnace opening machine is a device used on the top of the blast furnace, also known as the "opening machine" or "slag machine". It is mainly used to remove the accumulated slag in the blast furnace. After the blast furnace has been running for a period of time, the slag will accumulate at the bottom of the furnace body and needs to be discharged in time to keep the blast furnace running normally. The blast furnace opening machine opens the opening at the top of the blast furnace through mechanical or hydraulic devices, and discharges the slag from the bottom of the blast furnace for subsequent treatment or recycling. It plays an important role in ironmaking production. It can ensure the normal operation of the blast furnace, maintain production efficiency, and improve the utilization rate of waste slag. By using the blast furnace opening machine, operators can better control the slag process of the blast furnace and optimize the production process.

[0003] However, in the actual production process, the existing opening machine has high temperature and dust in front of the furnace. When using the blast furnace opening machine to open the iron mouth in front of the furnace, the slag will explode or spark during the discharge process. At the same time, the temperature is also very high, which poses a safety hazard. For this reason, we propose a furnace opening machine equipped with an atomizing spray device to solve the above technical problems. Utility Model Content

[0024] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

In addition, the terms "first", "second", "third" and the like are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0026] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] See also Figure 1-6, a furnace front opening machine equipped with an atomizing spray device, comprises a machine body 1, a spray structure is arranged at the front end of the machine body 1, the spray structure is used to adjust the spray length by a length adjusting structure, and the spray structure is used to adjust the spray width range by a width adjusting structure; the spray structure comprises a fixed ring 2 fixedly installed on the length adjusting structure, a spray hose 3 is passed through the fixed ring 2, a spray head is fixedly installed at the front end of the spray hose 3, and the end is connected to an external water pump, and the water pump provides spray water. By arranging an atomizing spray device at the front end of the furnace front opening machine, cooling water can be sprayed onto the slag to effectively reduce the temperature of the slag. The atomizing spray device maximizes the cooling effect by refining water into tiny water mist particles, so that the slag can be cooled quickly and prevented from explosion or sparks. In addition, the atomizing spray device can also reduce the diffusion of dust and exhaust gas caused by the slag discharge process. By using the atomizing spray device, the blast furnace operator can ensure the safety of the blast furnace opening and reduce the risks to the environment and personnel during the slag discharge process.

[0028] To adjust the spray range, please refer to Figure 1-3 and Figure 5 When the spraying range needs to be expanded, the push wheel 12 located between the two sets of fixed seats 8 is rotated, and the threaded rod 10 fixedly connected thereto is rotated, driving the moving blocks 9 threadedly connected at both ends to move forward and backward, so that the slide rail 4 fixedly connected to the moving block 9 moves forward and backward, thereby achieving the effect of adjusting the position of the spray hose 3 and realizing the function of adjusting the spraying range.

[0029] Among them, the fixed seat 8 and the movable block 9 are U-shaped, and the U-shaped setting can limit the movable block 9 inside the fixed seat 8, and a sliding groove is set on the inner side of the fixed seat 8, and a slidable limiting block 11 is set inside the sliding groove. The limiting block 11 is fixedly connected to the outer side of the movable block 9. The setting of the limiting block 11 and the sliding groove can ensure that when the movable block 9 is driven to move by the threaded rod 10, it will not cause displacement with the rotation of the threaded rod 10.

[0030] Among them, the threaded rod 10 is a bidirectional threaded rod, the threads at both ends are in opposite directions, and are respectively threadedly connected to two groups of moving blocks 9. The setting of the bidirectional thread can ensure that when the threaded rod 10 rotates, the symmetrically set moving blocks 9 can maintain the same moving action, thereby achieving the purpose of synchronous adjustment.

[0031] To adjust the spray position, refer to Figure 1-6When the spray hose 3 needs to move, the servo motor 5 is started, the screw rod 6 rotates, and the slider 7 threadedly connected to the outer wall of the screw rod 6 moves inside the slide rail 4, so that the fixed ring 2 fixedly installed on the top surface of the slider 7 moves, thereby driving the spray hose 3 inside the fixed ring 2 to move back and forth at the front end of the machine body 1, which has the effect of moving the spray head and realizes the adjustment of the spray position. This structure can adjust the spray position of the atomizing spray device according to actual production needs, so that the range of spray cooling can be adjusted, which can not only expand the spray range to achieve rapid cooling, but also narrow the spray range to achieve centralized cooling, thereby improving the practicality of the furnace front opening machine.
