Description

Technical Field

[0001] The invention belongs to the technical field of sintering, and in particular relates to a spiral water adding device for a sintering mixer with self-cleaning function. Background Art

[0002] Sintering mixing and granulation refers to the mixing of materials in a mixer by adding water and relying on the mixer's self-rotation. However, uneven water addition and sticking of materials in the mixer are common phenomena in the industry. Uneven water addition or sticking will affect the sintering process and have an important impact on the quality and energy consumption of sintered ore. Most traditional water addition methods use water pipes installed in the mixer, and water is added by drilling holes in the water pipes or using atomizing nozzles. Atomizing nozzles are easily clogged by sediment in the water during use, and improper handling will have a counterproductive effect; drilling holes to add water cannot fully atomize the water, resulting in over-wetting at the mixer's feed end and sticking of the mixer. Summary of the invention

[0003] The object of the present invention is to provide a spiral water adding device for a sintering mixer with self-cleaning function to solve the problems mentioned in the above background technology.

[0004] To achieve the above object, the present invention provides the following technical solutions:

[0005] A spiral water-adding device for a sintering mixer with self-cleaning function comprises a mixer, a steel structure, a steel wire rope, a fixed plate, a two-way water pipe, a support beam, a one-way water pipe, a water-adding branch pipe, and a spiral nozzle. There are two steel structures, which are relatively arranged on two sides of the mixer. The steel wire rope is connected between the two steel structures. A plurality of fixed plates are fixedly connected to the steel wire rope. The water inlet end of the two-way water pipe passes through the steel structure. The two-way water pipe is divided into an upper water pipe and a lower water pipe, both of which are fixed on the fixed plate. Water holes are respectively opened on the upper water pipe and the lower water pipe. The side of the steel structure is fixedly connected to the support beam. The one-way water pipe is fixed on the support beam. A plurality of water-adding branches are connected to the one-way water pipe. A spiral nozzle is connected to the end of each water-adding branch pipe.

[0006] Preferably, the spiral nozzle is inclined downward at 45°.

[0007] Preferably, the ends of the water supply pipe and the water supply pipe are both connected to two-way water drainage valves.

[0008] Preferably, a connecting valve is installed between the water supply pipe and the water supply pipe.

[0009] Preferably, the water supply pipe and the water supply pipe are equipped with manual valves at the feed end of the mixer.

[0010] Preferably, a water drain valve is installed at the end of the water pipe.

[0011] Preferably, the water holes are alternately distributed in the upper water pipe and the lower water pipe.

[0012] Compared with the prior art, the beneficial effects of the present invention are: on the one hand, the water can be fully dispersed through the spiral nozzle to avoid local over-wetting of the mixed material in the mixer, resulting in uneven mixing or sticking of the material; on the other hand, the self-cleaning effect of the two-way water can avoid sticking of the mixer for a long time, which is of great significance to the stability of sintering production and the quality of sintered ore.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] Example:

[0021] See also Figure 1 - Figure 5As shown, a spiral water adding device for a sintering mixer with self-cleaning comprises a mixer 1, a steel structure 2, a steel wire rope 3, a fixed plate 4, a two-way water pipe 5, a support beam 6, a one-way water pipe 7, a water adding branch pipe 8, and a spiral nozzle 9. There are two steel structures 2, which are arranged on both sides of the mixer 1 relatively, and the steel wire rope 3 is connected between the two steel structures 2. A plurality of fixed plates 4 are fixedly connected to the steel wire rope 3. The water inlet end of the two-way water pipe 5 passes through the steel structure 5. The two-way water pipe 5 is divided into an upper water pipe 21 and a lower water pipe 22, both of which are fixed on the fixed plate 4. Water holes 10 are respectively opened on the upper water pipe 21 and the lower water pipe 22. A support beam 6 is fixedly connected to the side of the steel structure 2, and the one-way water pipe 7 is fixed on the support beam 6. A plurality of water adding branches 8 are welded and connected to the one-way water pipe 7, and a spiral nozzle 9 is connected to the end of each water adding branch pipe 8.

[0022] The water adding method of the spiral water adding device of the sintering mixer with self-cleaning in this embodiment is divided into two ways. One way of water adding is to disperse and atomize the water through the spiral nozzle 9 to achieve uniform water adding, and the second way of water adding is mainly used to clean the mixer 1 to prevent sticking. The first way of water adding is to support the one way of water adding pipe 7 through the spiral nozzle 9 through the support beam 6 to add water. The spiral nozzle 9 is screwed on the water adding branch pipe 8 through its own bolts, and the water adding branch pipe 8 is connected to the one way of water pipe 7 through welding; the second way of water adding is to add water by drilling holes in all the upper water pipes 21 and the lower water pipes 22, and all the water adding pipes of the second way of water adding are fixed by hanging with the wire rope 3.

[0023] As a preferred implementation of this embodiment, the spiral nozzle 9 is inclined downward at 45 degrees.

[0024] As a preferred implementation of this embodiment, the ends of the water supply pipe 21 and the water supply pipe 22 are both connected to a two-way water drainage valve 11 .

[0025] As a preferred implementation of this embodiment, a communication valve 12 is installed between the water supply pipe 21 and the water supply pipe 22 .

[0026] As a preferred implementation of this embodiment, a manual valve 13 is installed at the feed end of the mixer 1 on the water supply pipe 21 and the water supply pipe 22 .

[0027] As a preferred implementation of this embodiment, a water drain valve 14 is installed at the end of the water pipeline 7.

[0028] As a preferred implementation of this embodiment, the water holes are alternately distributed in the upper water pipe 21 and the lower water pipe 22. There is no specific requirement for the number, interval and size of the water holes, which are determined according to actual conditions.

[0029] All pipes of the first and second water routes are equipped with drain valves at the end. Manual valves 13 are installed at the feed end of the mixer 1 for the upper and lower water pipes 21 and 22 of the second water route, so that the two water pipes can be switched freely. A connecting valve 12 is installed between the upper and lower water pipes 21 and 22 to adjust the water adding distance of the water pipes in the mixer 1. On the one hand, the water can be fully dispersed by the spiral nozzle 9 to avoid the local over-wetting of the mixed material in the mixer 1, resulting in uneven mixing or sticking of the material. On the other hand, the self-cleaning effect of the second water route can prevent the mixer 1 from sticking for a long time, which is of great significance to the stability of sintering production and the quality of sintered ore.

[0030] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
