Technical Field

[0001] The utility model relates to the field of sintering machines, in particular to a material loosening device for a sintering machine. Background Art

[0002] Sintering is a traditional process that converts powdered materials into dense bodies. People have long used this process to produce ceramics, powder metallurgy, refractory materials, ultra-high temperature materials, etc. The sintering machine is the main equipment in the exhaust sintering process. It can sinter concentrate powder and rich ore powder of different compositions and particle sizes into blocks, and partially eliminate harmful substances such as sulfur and phosphorus contained in the ore. Most sintering machines are equipped with loosening devices, especially when the raw material fraction is high and the sintering air permeability is poor, so loosening devices are indispensable. Loosening devices can effectively improve the air permeability of the original material layer of the mixed material.

[0003] In a Chinese patent, a loosening device on a sintering machine is disclosed, and its patent number is CN208419598U.

According to the loosening device on a sintering machine provided by the utility model, at least one slide groove is provided on the base plate, and at least one loosening rod slides in the slide groove and is fixed to the base plate through the connecting piece, so that the spacing between the loosening rods is adjustable, which can better adapt to the changes in the permeability distribution of the cross section of the sintering material caused by different sintering raw materials and different production conditions.

[0004] The above-mentioned published patents have the following disadvantages:

[0005] (1) In the prior art, during the use of the loosening device, since it is fixed in most cases, it is necessary to drive the sintering machine to drive the material to move and cooperate with the loosening device to perform the loosening operation, which makes it impossible to control the air permeability of the material, affecting the air permeability effect.

[0006] (2) In the prior art, when the loosening device is used, the movement of the material will cause a certain impact force to the loosening rod. If used for a long time, the loosening rod will be bent by the impact force, affecting the normal use of the subsequent loosening device.

[0007] (3) In the prior art, when the material passes through the surface of the loosening rod, some of the material will adhere to the surface of the loosening rod, hindering the loosening process of the loosening rod, causing uneven distribution of the material and affecting the loosening effect of the device.

[0033] like Figures 1 to 5 As shown, a sintering machine loosening device includes a support plate 1, a circular hole is arranged on the surface of the support plate 1 for connecting the loosening rod 2, a plurality of air holes 201 are arranged on the surface of the loosening rod 2 for facilitating the outflow of steam, a buffer member 3 located at one end of the loosening rod 2 buffers the impact on the loosening rod 2, a fixed cylinder 4 fixed on the inner side of the buffer member 3 fixes the loosening rod 2, and a steam pipe 404 is connected to one end of the fixed cylinder 4 to transport steam to the air hole 201, a fixed plate 5 fixed on the upper end of the support plate 1 is used to connect the driving component 6, and the driving component 6 is provided with a driving motor 601, and the driving motor 601 drives the turntable 1 602 to rotate, so that the turntable 1 602 and the turntable 2 603 on one side thereof can drive the special-shaped tooth block 606 to rotate through the driving rod 605, so that the worm 607 between the two special-shaped tooth blocks 606 can drive the cleaning plate 7 arranged at one end to move back and forth, and the surface of the loosening rod 2 is cleaned by using the plurality of cleaning rings 701 on the surface of the cleaning plate 7.

[0034] A slide groove 301 is arranged on the surface of the support plate 1 , and the buffer member 3 slides inside the slide groove 301 , and a spring 302 connected to the buffer member 3 is arranged inside the slide groove 301 .

[0035] Through the above technical solution, under the elastic force of the spring 302, the buffer member 3 can drive the loosening rod 2 to slide inside the slide groove 301, thereby reducing the impact on the loosening rod 2 and extending the service life of the loosening rod 2.
