Problems solved by technology

[0011] For the above two ring-shaped sintering machines, the rotary part includes multiple bellows arranged in a ring, that is, the bellows rotate with the grate bed and sintering ore. Because the width of the grate bed of a large sintering machine is 5m, the rotation diameter is 50~60m, and the height of the bellows is 3~ 5m, coupled with the negative pressure of the exhaust fan, the rotating weight is very large, and the pressure requirements for the track and wheels are relatively high; the cross section of the sintered cake reaches 5000mmx800mm, and it is very difficult to cut; the cutting device and the active push-down unloading device work It must move synchronously with the rotary part and the sintered cake, and the mechanism is complex

Embodiment 1

[0090] Example 1, such as Figure 1~Figure 9 shown.

[0091] The water-sealed annular sintering machine consists of a transmission device 1, a traveling device 2, a revolving body 3 (the inner and outer revolving frames 31, the inner and outer fences 32, and connecting beams 34 together constitute the revolving body 3), grate bars 4, support frames 5, and support Platform 6, bellows 7 etc. are formed. The revolving body 3 is driven by the transmission device 1 to rotate around the same center.

[0092] The grate bar 4 is installed on the support frame 5, and the support frame 5 is hinged to the lower part of the connecting beam 34; the water-sealed annular sintering machine is divided into a material distribution area I, an ignition area II, a sintering work area III and a discharge area IV, at the beginning of the work area , the support frame 5 is locked by the locking device 9. In the material distribution area, the mixed material is unloaded onto the support frame 5 and ...

Embodiment 2

[0098] Example 2, such as Figure 10~Figure 16 shown.

[0099] This embodiment is a change carried out on the basis of Embodiment 1, and its main difference with Embodiment 1 is:

[0100] First, the running device 2 is made up of the inner track 21, the outer track 22 and the wheels 23; the wheels 23 are fixed on the bottom of the revolving frame 31 and rotate with the revolving body 3; the inner track 21 and the outer track 22 are fixed on the support platform 6; The inner and outer rails 21, 22 move, and the inner and outer rails 21, 22 support the rotary body 3 and the weight of the material through the wheels 23. ,

[0101] Second, the guiding device 11 in the unloading area is a curved rail, located at the bottom of the support frame 5 in the unloading area, and within the scope of the support frame 5, the shape is a continuous irregular concave shape, and the lower end of the support frame 5 has increased scroll wheel.

[0102]The 3rd, locking device is cam locking d...

Embodiment 3

[0104] Example 3, such as Figure 16 shown.

[0105] This embodiment is a change carried out on the basis of Embodiment 1. Its main difference from Embodiment 1 is that the sealing plate 33 is removed, and the upper end of the water sealing knife 105 of the annular continuous water sealing device 10 is connected to the fence. 32, the rest of the content is the same as in Embodiment 1, which can be interpreted from the relevant description of Embodiment 1.

Abstract

The invention provides an annular sintering machine for water seal. Inner and outer-side breast boards, a connecting beam and inner and outer-side rotating frame form a rotating body together, and an annular water seal device is arranged under the rotating body and is positioned between the lower part of the rotating body and a bellows; the water seal device is an annular continuous body, and comprises an inner-side annular water seal device and an outer-side annular water seal device. A grid section is arranged on a supporting rack, one end of the supporting rack is connected with the connecting beam, and the other end of the supporting rack is suspended; the suspended end of the supporting rack and the rotating body are locked by a locking device; before entering a discharge area and when leaving the discharge area, an unlocking device and a locking device of the supporting rack are respectively arranged; a guidance device for turning the supporting rack down is arranged in the discharge area. The annular water seal structure is realized, the sealing effect is improved, and the air leakage amount is reduced by 30 to 40%; the rotating structure is simple, the weight is light, and the cost is low; through the improvement on a walking device, the number of air leakage points is reduced, and further the air leakage rate is reduced; the power consumption is reduced, and the operating environment is improved.

Description

technical field [0001] The invention relates to a water-sealed annular sintering machine, which belongs to the field of metallurgical equipment. Background technique [0002] The sintering production of the metallurgical system is to mix iron ore powder, fuel, flux, and returned ore in a certain proportion, put them into the sintering equipment and ignite and burn them. The process of joining into blocks. [0003] The equipment that completes the sintering process is the sintering machine. The temperature of the sinter produced by the sintering machine is still as high as about 700 degrees after being crushed. It needs to be cooled to about 100 degrees in the cooler (including ring cooler and belt cooler) before being sent Subsequent processes are processed, so the sintering machine and cooling machine are important equipment for sintering production. [0004] Currently, belt-type sintering machines are commonly used in sintering machines. Due to structural limitations, th...
