Description

Technical Field

[0001] This utility model belongs to the field of sintering technology, specifically relating to a spiral water adding device for a sintering mixer with self-cleaning function. Background Technology

[0002] Sintering mixing and granulation refer to the process of mixing materials in a mixer by adding water and relying on the mixer's rotation. However, uneven water addition and material sticking to the mixer are common problems in the industry. Uneven water addition or material sticking will affect the sintering process and have a significant impact on the quality of sinter and energy consumption. Traditional water addition methods mostly involve installing water pipes inside the mixer and drilling holes in the pipes or using atomizing nozzles. Atomizing nozzles are easily clogged by sediment in the water during use, and improper handling can have the opposite effect; adding water through drilling holes cannot atomize the water sufficiently, resulting in excessive wetness at the feed end of the mixer and material sticking to the mixer. Utility Model Content

[0003] The purpose of this invention is to provide a self-cleaning spiral water supply device for a sintering mixer to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A self-cleaning spiral water supply device for a sintering mixer includes a mixer, a steel structure, a steel wire rope, a fixing plate, two water pipes, a support beam, a first water pipe, water supply branch pipes, and a spiral nozzle. Two steel structures are arranged opposite each other on both sides of the mixer. A steel wire rope connects the two steel structures, and several fixing plates are fixedly connected to the steel wire rope. The inlet ends of the two water pipes pass through the steel structure. The two water pipes are divided into an upper water pipe and a lower water pipe, both fixed to the fixing plates. Water holes are opened on the upper and lower water pipes respectively. A support beam is fixedly connected to the side of the steel structure. The first water pipe is fixed to the support beam, and several water supply branch pipes are connected to the first water pipe. A spiral nozzle is connected to the end of each water supply branch pipe.

[0006] Preferably, the spiral nozzle is tilted downwards at a 45° angle.

[0007] Preferably, both the water inlet pipe and the water outlet pipe are connected to a dual-channel drain valve.

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

[0009] Preferably, manual valves are installed at the feed end of the mixer for both the water inlet pipe and the water outlet pipe.

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

[0011] Preferably, the water inlets are alternately distributed in the water supply pipe and the water supply pipe.

[0012] Compared with the prior art, the beneficial effects of this utility model are: on the one hand, the water can be fully dispersed by the spiral nozzle, avoiding local over-wetting of the mixed material in the mixer, which would lead to uneven mixing or sticking; on the other hand, the self-cleaning effect of the two water channels can prevent the material from sticking in the mixer for a long time, which is of great significance to the stability of sintering production and the quality of sintered ore.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example:

[0021] Please see Figure 1 - Figure 5As shown, a self-cleaning spiral water supply device for a sintering mixer includes a mixer 1, a steel structure 2, a steel wire rope 3, a fixing plate 4, two water pipes 5, a support beam 6, a single water pipe 7, water supply branch pipes 8, and a spiral nozzle 9. There are two steel structures 2, positioned opposite each other on both sides of the mixer 1. A steel wire rope 3 connects the two steel structures 2, and several fixing plates 4 are fixedly connected to the steel wire rope 3. The inlet end of the two water pipes 5 passes through the steel structure 5. The two water pipes 5 are divided into an upper water pipe 21 and a lower water pipe 22, both fixed to the fixing plates 4. Water inlets 10 are opened on the upper water pipe 21 and the lower water pipe 22 respectively. A support beam 6 is fixedly connected to the side of the steel structure 2. A single water pipe 7 is fixed to the support beam 6, and several water supply branch pipes 8 are welded to the single water pipe 7. Each water supply branch pipe 8 is connected to a spiral nozzle 9 at its end.

[0022] In this embodiment, the self-cleaning sintering mixer with spiral water supply device has two water supply channels. One channel disperses and atomizes the water through spiral nozzles 9 to achieve uniform water supply. The second channel mainly serves to clean the mixer 1 and prevent material from sticking. The first water supply channel is supported by a support beam 6, which supports a water supply pipe 7 and delivers water through the spiral nozzles 9. The spiral nozzles 9 are bolted to the water supply branch pipes 8, which are connected to the first water pipe 7 by welding. The second water supply channel delivers water by drilling holes in all the upper and lower water pipes 21 and 22. All the water supply pipes in the second channel are fixed by steel wire ropes 3.

[0023] In a preferred embodiment of this invention, the spiral nozzle 9 is tilted downwards at a 45° angle.

[0024] In a preferred embodiment of this invention, both the water inlet pipe 21 and the water outlet pipe 22 are connected to a dual-channel drain valve 11.

[0025] In a preferred embodiment of this invention, a connecting valve 12 is installed between the water inlet pipe 21 and the water outlet pipe 22.

[0026] In a preferred embodiment of this invention, manual valves 13 are installed on the inlet pipe 21 and the outlet pipe 22 at the feed end of the mixer 1.

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

[0028] In a preferred embodiment of this invention, the water inlets are alternately distributed on the inlet pipe 21 and the outlet pipe 22. The number, spacing, and size of the water inlets are not specifically required and can be determined according to the actual situation.

[0029] All water supply lines, both primary and secondary, are equipped with drain valves at their ends. Manual valves 13 are installed at the feed inlet of mixer 1 for the secondary water supply line 21 and 22, allowing for free switching between the two lines. Connecting valves 12 are installed between the primary and secondary water supply lines 21 and 22 to adjust the water supply distance within mixer 1. This system effectively disperses water through the spiral nozzles 9, preventing localized over-wetting of the mixed material in mixer 1, which could lead to uneven mixing or material sticking. Furthermore, the self-cleaning function of the secondary water supply line prevents material sticking to mixer 1 over extended periods, which is crucial for the stability of sintering production and the quality of the sintered ore.

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