Description

Technical Field

[0001] The utility model relates to the technical field of material preparation equipment, and more specifically to a transmission system of a primary cooling section granulated hot slag annular discharge device. Background Art

[0002] Slag is a by-product of the ironmaking / ferroalloy production process and contains abundant resources. The treatment process of high-temperature molten slag generally involves first granulating the high-temperature melt using a slag granulator, and then reprocessing the granulated particles to achieve product reuse.

[0003] After the high-temperature melt is granulated by the granulating device, the temperature of the granulated slag in the primary cooling section is about 800°C. The temperature of the granulated slag at about 800°C has reached below the mineral crystallization temperature and can be unloaded. When unloading, the granulated slag falls along a ring channel of the granulating device. The fallen granulated slag needs to be continuously collected to meet the requirements of industrial continuous production.

[0004] The granular slag at about 800°C falls vertically from the annular channel at 360°. If it falls directly on the ground and is then collected, there are certain requirements on the amount of slag and the collection speed of the granular slag on the ground, and the ground where the granular slag falls will be damaged to a certain extent, which is not suitable for the continuous production of batch granular slag. Therefore, in response to the above problems, our unit has proposed an annular unloading device, which uses an annular unloading plate to receive the high-temperature granular slag that falls vertically from the annular unloading channel of the granulating device, and then rotates the annular unloading plate to unload the granular slag at a preset unloading position using a preset scratching plate. Since it is necessary to ensure that the annular unloading plate can rotate smoothly in this process and the annular unloading plate is large in size, ordinary rotating transmission equipment in the prior art, such as bearings or rotating shafts, transmission chains, etc., are difficult to be applied to the annular unloading plate. Therefore, the current prior art lacks a transmission system that can provide smooth rotational power for the annular unloading device. Utility Model Content

[0034] In view of the problem that the above-mentioned prior art lacks a transmission system that can provide smooth rotational power for the annular discharge device, a transmission system for a primary cooling stage granulated hot slag annular discharge device is proposed.

[0035] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0036] In order to explain the transmission system of the primary cooling section granulated hot slag annular discharge device provided by the utility model, Figure 1 The top view structure of the transmission system of the annular discharge device for hot granulated slag in the primary cooling stage according to the embodiment of the utility model is shown; Figure 2 The side structure of the support device according to the embodiment of the utility model is shown; Figure 3 The main view structure of the inner support roller according to the embodiment of the utility model is shown; Figure 4 The side view structure of the inner support roller according to the embodiment of the utility model is shown; Figure 5 The main view structure of the outer support roller according to the embodiment of the utility model is shown; Figure 6 The side view structure of the outer support roller according to the embodiment of the utility model is shown; Figure 7 The side installation structure of the drive device and the clamping mechanism according to the embodiment of the utility model is shown; Figure 8 The side mounting structure of the speed measuring gear according to the embodiment of the utility model is shown.

[0037] like Figures 1 to 8 As shown together, the transmission system of the annular discharge device of granulated hot slag in the primary cooling stage provided by the utility model includes a supporting device, a driving device 2 and a clamping mechanism 3; wherein the supporting device includes an inner supporting roller 11 arranged at the bottom of the inner ring of the annular discharge plate 4 of the annular discharge device of granulated hot slag in the primary cooling stage and an outer supporting roller 12 arranged at the bottom of the outer ring of the annular discharge plate 4; the driving device includes a driving mechanism 21, a transmission gear 22 sleeved on the upper part of the driving mechanism 21 and a pin tooth 23 arranged on the outer side wall of the annular discharge plate 4; the transmission gear 22 is meshed with the pin tooth 23; the clamping mechanism includes a telescopic rod mechanism 31 arranged on one side of the transmission gear 22; the telescopic rod body of the telescopic rod mechanism 31 is connected to the driving mechanism 21; when the telescopic rod body is in an extended state, the transmission gear 22 on the upper part of the driving mechanism 21 connected to the telescopic rod body is pressed on the pin tooth 23, and the driving mechanism 21 drives the pin tooth 23; when the telescopic rod body is in a retracted state, the transmission gear 22 is disengaged from the pin tooth 23, and the driving mechanism 21 stops driving the pin tooth 23.

[0038] As a preferred solution of the present invention, a fixing platform is provided at the bottom of the driving mechanism 21; the fixing platform includes a base 24 and a mounting platform 25 slidably provided on the top of the base 24 through a slide rail; the bottom of the driving mechanism 21 is provided on the top of the mounting platform 25, the base 24 is detachably fixed on the concrete foundation, and the telescopic rod mechanism 31 is fixed on the outer end of the base 24.

[0039] As a preferred solution of the present invention, a fixed-distance tooth 6 is provided between the annular discharge plate 4 and the pin tooth 23. The center distance between the transmission gear 22 and the pin tooth 23 when meshing can be ensured.

[0040] It should be noted that the transmission system provided by the utility model can be applied to the annular unloading device for granulated hot slag in the primary cooling stage proposed by this unit. In the prior art, after the melt is granulated in the primary cooling stage, it generally needs to be cooled twice or multiple times before the granulated slag is unloaded and collected. At this time, the temperature of the granulated slag can be unloaded by conventional unloading equipment on the market. In the actual process flow, the temperature of the granulated slag in the primary cooling stage is about 800°C. The temperature of the granulated slag at about 800°C has reached below the mineral crystallization temperature, and it can actually be unloaded, thereby saving the subsequent multiple cooling processes. However, the granular slag at about 800°C falls vertically from the annular channel at 360°. If it falls directly on the ground and is then collected, there are certain requirements on the amount of slag and the collection speed of the granular slag on the ground, and the ground where the granular slag falls will be damaged to a certain extent, which is not suitable for continuous production of batch granular slag. In order to solve the problem of difficult unloading of granular slag after granulation in the primary cooling stage in the prior art, this unit has proposed an annular unloading device, which uses an annular unloading plate to receive the high-temperature granular slag falling vertically from the annular unloading channel of the granulating device, and then rotates the annular unloading plate to unload the granular slag at a preset unloading position using a preset scratching plate. Although it can effectively solve the problem of unloading in the primary cooling stage of the granulating device, it is necessary to ensure that the annular unloading plate can rotate smoothly in this process, and the annular unloading plate is large in size. Therefore, ordinary rotating transmission equipment in the prior art, such as bearings or rotating shafts, transmission chains, etc., are difficult to be applied to the annular unloading plate. Based on this, the utility model provides a transmission system that provides rotational power for an annular unloading device for granulated hot slag in the primary cooling stage.

End covers are arranged at both ends of the inner roller 114, and the end covers are detachably connected to the ends of the inner roller 114 by bolts, thereby protecting the rollers. At the ends of the inner roller shaft 112 located outside the side frames, the inner roller shaft 112 can be fixed to the side frames by setting a shaft stop 115, thereby protecting the first bearing 113 and preventing leakage of the internal lubricating fluid.

[0044] It should be noted that the “inside” and “outside” in the present invention refer to the positional relationship of the annular discharge tray 4 and have no other special meanings.
