For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood in combination with specific circumstances.

[0030] The following will refer to the attached Figures 1 to 4 The utility model is described in detail in conjunction with the embodiments.

[0031] In general, the utility model relates to a material loosener, comprising a heating tube 2, a fixed frame 1 fixedly connected to the heating tube 2, and a material loosening rod 5 connected to the end of the heating tube 2 through a connecting assembly, the first openings 503 opened around the side wall of the material loosening rod 5 form a group, and multiple groups are arranged at intervals along the length direction of the material loosening rod 5, the end of the material loosening rod 5 is provided with a bottom end 502, and a plurality of second openings 504 are spaced apart on the bottom end 502.

[0032] In the utility model, the heating tube 2 is used to introduce the external mixed material hot air into the loosening rod 5, and also plays a role in fixing the loosening rod 5. The loosening rod 5 is inserted into the material pile. After the hot air enters the loosening rod 5, it is ejected from the first opening 503 and the second opening 504, which increases the material temperature and the oxygen content between the mixed materials, thereby improving the oxidizing atmosphere of the sintering process, which is beneficial to improving the quality of the sintered ore and reducing fuel consumption.

[0033] In addition, the arrangement of the first openings 503 of each group may also be arranged in an up-and-down arrangement, which is not further limited herein.

[0034] Preferably, a plurality of heating tubes 2 are arranged at intervals on the fixed frame 1, and the plurality of heating tubes 2 are connected to a plurality of loosening rods 5. Specifically, 10-15 heating tubes 2 are arranged on the fixed frame 1, and the number gradually decreases from bottom to top, and the number of the upper layer is 3-5 less than that of the lower layer, and the distance between each adjacent heating tube is consistent, so as to ensure that the air permeability of the sintered cloth is getting better from top to bottom.

[0035] Among them, Figure 2 As shown, the above-mentioned fixed frame 1 includes a first fixed plate 101, a second fixed plate 102 and a third fixed plate 103 arranged in parallel and a connecting plate 104. The first fixed plate 101 and the second fixed plate 102 are tightly fitted and welded together, and there is a gap between the third fixed plate 103 and the second fixed plate 102. The connecting plate 104 is fixedly welded to the surrounding sides of the first fixed plate 101, the second fixed plate 102 and the third fixed plate 103.

[0036] In specific implementation, the heating tube 2 passes through between the first fixing plate 101 and the second fixing plate 102 , passes through the second fixing plate 102 , enters the third fixing plate 103 through the gap, and finally passes through the third fixing plate 103 .

[0037] It should be noted that if Figure 2 As shown, the first fixing plate 101 and the second fixing plate 102 clamp and weld the heating tube 2, ensuring the horizontal reliability of the heating tube 2. The third fixing plate 103 fixes the connection end of the heating tube 2 and the loose material rod 5, reduces and avoids the sagging and deformation of the end, and ensures the horizontal stability of the loose material rod 5 during operation. The connecting plate 104104 connects and fixes the first fixing plate 101, the second fixing plate 102 and the third fixing plate 103, fixes them into a whole, and improves the overall structural reliability.

[0038] In order to facilitate the loose material rod 5 to extend into the material pile better, Figure 1 and Figure 2 As shown, in this embodiment, the heating tube 2 vertically penetrates from the second fixing plate 102 to the third fixing plate 103. Figure 2 As shown, the opening angle of the first opening 503 is 40-60 degrees. Such opening can match the opening with the material stacking angle, ensuring that all the hot air in the first opening 503 is sprayed toward the material.

[0039] As a preferred method, the loosening rod 5 is made of wear-resistant oval tube steel with a diameter of 20 mm. The chords on both sides of the oval wear-resistant steel tube can be vertically welded to the trolley to improve stability. The loosening rod 5 is preferably made of K360 wear-resistant steel

[0040] After the loosening rod 5 has been used for a period of time, the end of the loosening rod 5 begins to sag and become severely worn and thinner, and the loosening height position and loosening pores change, which reduces the loosening effect and fails to improve the air permeability of the material layer, causing the load of the exhaust fan to increase, the output to decrease, and the energy consumption to increase. When the material directly rubs against the loosening rod 5, because the material is composed of hard particles such as iron ore powder and iron oxide, the friction between the loosening rod 5 and the material is large when the trolley is running, which causes great wear on the loosening rod 5, shortens the life of the loosening rod 5, and requires shutdown for replacement, which has a great impact on both output and quality.

[0041] Based on the above arrangement, a side wing 501 is fixedly provided on the right side of each group of first openings 503. The side wing 501 of the material loosening rod 5 of the utility model has two functions: first, when the trolley is running, the side wing 501 rubs against the material, reducing the wear of the material on the material loosening rod 5. Second, the side wing 501 blocks the material that blocks the first opening 503 on the material loosening rod 5.

[0042] It should be noted that if Figure 3 As shown, the angle between the side wing 501 and the loosening rod 5 is 45 degrees. With this arrangement, the side wing 501 can achieve the best shielding effect and prevent a large amount of material from clogging the exhaust hole of the loosening rod 5. When the trolley is running, the mixed material contacts and rubs against the side wing 501, which reduces the direct friction of the iron-containing material on the loosening rod 5, reduces the wear degree of the loosening rod 5, and extends the service life of the loosening rod 5.

[0043] like Figure 2 and Figure 3 As shown, the connecting assembly includes a connecting tube 3 and a connecting screw 4. One end of the connecting tube 3 is connected to the heating tube 2, and the other end is connected to the loose material rod 5. The connecting screw is screwed at the connection between the connecting tube 3 and the heating tube 2 rod.

[0044] In this embodiment, the connecting tube 3 has the effect of changing the diameter, connecting the heating tube 2 and the loosening rod 5, and the connecting screw 4 has the effect of fixing. In specific implementation, when the loosening rod 5 is severely worn, the loosening rod 5 can be partially disassembled and installed separately through the connecting screw 4, which is convenient for replacement and simple for operation.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
