[0002] The drum mixer is one of the main equipment in the sintering project. Its function is to moisten and mix the prepared sintering mixture so that the water, materials and ingredients in the mixture are evenly mixed. Usually, a certain amount of water needs to be sprayed during the production process of the drum mixer to make the materials mix evenly to form a particle size that meets the process requirements. A water spray device needs to be installed inside the drum mixer.

[0003] During the installation of large-scale drum mixer equipment, the height of the water spray device nozzle from the mixed material inside the drum mixer cylinder needs to be adjusted to a suitable position. If it is too low, the drum mixer material is easy to splash onto the water spray device nozzle, causing the water spray device to stick to the material and may also cause blockage. Therefore, it is necessary to design an adjustment mechanism for the drum mixer water spray device. Utility Model Content

[0031] It should be noted that: unless otherwise defined, the technical terms or scientific terms used in this article should be understood by people with ordinary skills in the field to which the utility model belongs. The words "one", "an" or "the" and the like used in the patent application specification and claims of this utility model do not express quantitative restrictions, but indicate the existence of at least one; the "first", "second" and "third" used in this article should not be regarded as restrictions on the order of components, but are only used to distinguish different components; "include" or "comprise" and other similar words indicate that the elements or objects appearing before "include" or "comprise" include the elements or objects listed after "include" or "comprise" and their equivalents, but do not exclude other elements or objects with the same function.

[0032] In order to more clearly describe the specific structural composition of the adjustment mechanism for the water spraying device of the drum mixer, Figure 1-2 Describe this embodiment:

[0033] like Figure 1As shown, an adjustment mechanism for a water spraying device of a drum mixer comprises a bracket seat 1 and a support 2 (a stand for connecting the support 2 is arranged on the ground, and the stand is not shown in the figure) arranged on both sides of the drum mixer, and a steel wire rope 3 between the bracket seat 1 and the support 2; the steel wire rope 3 comprises a winding portion 301 and a transverse hanging portion 302, and the free end of the hanging portion 302 transversely passes through the inner cavity of the drum mixer and is fixedly connected to the support 2.

[0034] It is worth noting that the winding portion 301 and the hanging portion 302 merely divide the steel wire rope 3 into two parts according to their functions, and there is no fixed / obvious boundary between the two parts. When the length of the steel wire rope 3 is constant, the length of the winding portion 301 increases, the length of the hanging portion 302 decreases, the hanging portion 302 becomes tense, and the whole tends to be horizontal. On the contrary, when the length of the winding portion 301 decreases, the length of the hanging portion 302 increases, the hanging portion 302 becomes loose, and the whole tends to sag.

[0035] The support seat 1 is provided with a rope winding mechanism for winding the winding part 301, and the rope winding mechanism adjusts the tightness of the hanging part 302 during winding; a plurality of connecting plates 4 are provided on the hanging part 302, and a water spraying device 5 is connected to the lower end of the connecting plate 4, and the water spraying device 5 rises or falls in the inner cavity of the drum mixer as the tightness of the hanging part 302 is adjusted. The water spraying device 5 passes through the drum mixer along with the steel wire rope 3, and a plurality of nozzles are provided on the lower side of the water spraying device 5, and water is sprayed to the material in the drum mixer through the nozzles below after being connected to an external water source.

[0036] The height of the water spray device 5 is adjusted by controlling the tension of the steel wire rope 3, which is easy to control and suitable for use in a large-span drum mixer. Only the steel wire rope 3 and the water spray device 5 are in the drum mixer, and the layout is simple; the height of the water spray device 5 is adaptively adjusted to prevent the mixed material in the drum mixer from splashing and clogging the nozzle, without affecting the water spraying on the mixed material.

[0037] In the above embodiment, the steel wire rope 3 and the water spraying device 5 are connected by a plurality of connecting plates 4. The multi-point connection can maintain uniform force even if the span of the water spraying device 5 is large, thereby ensuring the stability of the water spraying device during lifting and lowering.

[0038] In the above embodiment, the specific method of the support 2 and the wire rope 3 is: the free end of the hanging part 302 is bent and fixed by the rope clamp 7 to form a ring; the support 2 is rotatably connected with the pin shaft 6, and the pin shaft 6 passes through the ring sleeve at the free end of the hanging part 302.

[0039] See also Figure 2 , the rope winding mechanism includes a drum, a worm reducer 8 and a hand wheel 9;

[0040] Specifically, the drum is rotatably arranged on the bracket seat 1, the housing of the worm reducer 8 is fixed on the bracket seat 1, the input shaft of the worm reducer 8 is fixedly connected to the hand wheel 9, and the output shaft of the worm reducer 8 is fixedly connected to the drum through the coupling 10. During use, the operator rotates the hand wheel 9, the worm reducer 8 decelerates, and the drum rotates to adjust the tightness of the wire rope 3, which is convenient to control and the parts are easy to process; the worm reducer 8 also has the function of preventing the drum from loosening.

[0041] The coupling 10 may be a ball coupling.

[0042] The drum structure specifically includes a drum body 11 for winding a winding portion 301 for winding a steel wire rope 3, and a fixing plate 12 for fixing the free end of the winding portion 301 on the drum body 11; a drum shaft 13 is fixed at both ends of the drum body 11, and a shaft seat for the drum shaft 13 to pass through is provided on the bracket seat 1. The drum body 11 and the drum shaft 13 rotate synchronously, and the two can be integrally formed. A rope groove for arranging the hanging portion 302 is provided on the circumferential surface of the drum body 11, and the steel wire rope is in the rope groove when winding to avoid sliding.

[0043] In order to prevent the reel shaft from reversing or sliding, a check valve 14 is flexibly connected to the bracket seat 1, and the check valve 14 is fixedly connected to one end of the reel through a shaft key.

[0044] In order to ensure the stability of the water spray device 5 when it is raised or lowered, a vertical slide groove 15 for the water spray device 5 to rise or fall is provided on the bracket seat 1. The water spray device 5 is raised or lowered along the vertical slide groove 15 to reduce possible swinging.

[0045] Next, an overview of the use of the adjustment mechanism for the water spraying device of the drum mixer is given: the water spraying device 5 passes through the inner cavity of the drum mixer and sprays water on the material inside. When the height of the water spraying device 5 needs to be adjusted, the input shaft of the worm reducer 8 is driven to rotate by the hand wheel 9, and the output shaft of the worm reducer 8 drives the drum to rotate through the coupling 10. The wire rope 3 adjusts the length of the hanging part 302, that is, the tightness of the hanging part 302, during the winding or releasing process. The hanging part 302 is connected to the water spraying device 5 through the connecting plate 4. The water spraying device 5 moves to a suitable height along the vertical slide 15 as the tightness of the hanging part 302 is adjusted, and water is sprayed to the material through the nozzle of the water spraying device 5.

[0046] The parts not described in detail in this embodiment are prior art.

[0047] It should be noted that although the utility model is described through the above embodiments, the utility model can also have other multiple embodiments. Without departing from the spirit and scope of the utility model, it is obvious that those skilled in the art can make various corresponding changes and deformations to the utility model, but these changes and deformations should all fall within the scope of protection of the attached claims of the utility model and their equivalents.
