Description

Technical Field

[0001] The utility model relates to the technical field of rotary cooling furnaces, in particular to a material receiving device for a rotary cooling furnace. Background Art

[0002] The rotary cooling furnace uses circulating water to flow in the jacket layer of the rotary kiln. The cooled material enters the central cylinder of the cooling furnace through the cooling furnace head material sealing pipe. The cooling circulating water does not directly contact the cooled material. The flowing cooling circulating water is used to take away the heat of the material in the cooling furnace cylinder, so as to achieve the effect of rapidly cooling the material temperature. The temperature of the material before entering the cooling furnace is about 560℃, and the temperature of the material after being discharged from the cooling furnace is about 38℃, and the cooling effect is good.

[0003] The commonly used material transfer device for rotary cooling furnaces in the prior art is direct pipeline delivery. However, in the actual production process, because semi-coke is produced at high temperature and contains coal gas, the material must be isolated from the outside world, and the material line must be in a continuous state. If the material level detection is inaccurate, the process personnel cannot grasp the material line status in real time, and it is easy for the material seal to fail to achieve the effect, causing coal gas to enter the cooling furnace and leak out, which poses a great hidden danger to personnel safety. Utility Model Content

[0004] The utility model aims to provide a rotary cooling furnace receiving device, which can ensure that the material line in the receiving bin is uniform and ensure that the pipeline from the retorting furnace discharge box to the cooling furnace head feeding rotary valve is unobstructed.

[0006] Furthermore, it includes a cooling furnace head feed plug valve, which is connected between the discharge port at the bottom of the cooling furnace receiving bin and the feed port at the top of the cooling furnace head feed rotary valve.

[0007] Furthermore, the cooling furnace receiving bin is connected with a material level meter II and a material level meter III, the material level meter II is connected to the upper part of the cooling furnace receiving bin, and the material level meter III is connected to the lower part of the cooling furnace receiving bin.

[0008] Furthermore, a cooling furnace receiving bin electric vibrator is fixedly connected to the outer wall of the cooling furnace receiving bin.

[0009] Furthermore, the inner diameter of the cooling furnace receiving bin is larger than the inner diameter of the plug valve of the retorting furnace discharge box.

[0010] Furthermore, the cooling furnace head feed rotary valve is frequency-variable.

[0011] The beneficial effects of the utility model are: the device of the utility model has low cost, convenient transformation, reliable use, simple installation, simple operation, and easy maintenance. It solves the problem of frequent material expansion in the cooling furnace head drop pipe, avoids gas poisoning accidents caused by inaccurate judgment of personnel due to the material expansion phenomenon, and ensures smooth material reception of the rotary cooling furnace.

DETAILED DESCRIPTION

[0014] like Figure 1 As shown, the utility model is a rotary cooling furnace receiving device comprising a retort furnace barrel 1, a retort furnace discharge box 2, a retort furnace discharge box plug valve 3, a cooling furnace head feed rotary valve 6 and a material level meter Ⅰ8, the cooling furnace head feed rotary valve 6 is frequency conversion, and also includes a cooling furnace receiving bin 4, the retort furnace discharge box 2 is connected to the tail of the retort furnace barrel 1, the retort furnace discharge box plug valve 3 is connected to the bottom discharge port of the retort furnace discharge box 2, the top of the cooling furnace receiving bin 4 is the feed port, the bottom of the cooling furnace receiving bin 4 is the discharge port, and the top feed port of the cooling furnace receiving bin 4 is connected to the retort furnace discharge box plug valve The plate valve 3 is away from one end of the retort discharging box 2, the top feed port of the cooling furnace head feed rotary valve 6 is connected to the bottom feed port of the cooling furnace receiving bin 4, and includes a cooling furnace head feed plug valve 5, the cooling furnace head feed plug valve 5 is connected between the bottom feed port of the cooling furnace receiving bin 4 and the top feed port of the cooling furnace head feed rotary valve 6, the level meter I8 is connected to the upper part of the retort discharging box 2, the cooling furnace receiving bin 4 is connected with the level meter II9 and the level meter III10, the level meter II9 is ​​connected to the upper part of the cooling furnace receiving bin 4, and the level meter III10 is connected to the lower part of the cooling furnace receiving bin 4.

[0015] The outer wall of the cooling furnace receiving bin 4 is fixedly connected with a cooling furnace receiving bin electric vibrator 7 .

[0016] The inner diameter of the cooling furnace receiving bin 4 is larger than the inner diameter of the plug valve 3 of the retorting furnace discharge box.

[0017] The material operation process of the utility model is as follows: the material inside the retort furnace cylinder 1 enters the retort furnace discharge box 2, the material in the retort furnace discharge box 2 enters the cooling furnace receiving bin 4 through the retort furnace discharge box plug valve 3, the material in the cooling furnace receiving bin 4 enters the cooling furnace head feed rotary valve 6 through the cooling furnace head feed plug valve 5, the internal blades of the cooling furnace head feed rotary valve 6 rotate to transport the material into the cooling furnace head, and since the material level meter Ⅰ8 is connected to the upper part of the retort furnace discharge box 2, when the material level meter Ⅰ8 detects the material, it means that the material has a large accumulation in the retort furnace discharge box 2, and at this time, it is necessary to increase the cooling furnace head feed. The frequency of the rotary valve 6 is used to speed up the material delivery speed and thus reduce the material line; the normal state of the material level meter Ⅱ9 should be able to detect the material. When the material level meter Ⅱ9 cannot detect the material, it means that the material line is too low. At this time, the feeding frequency of the cooling furnace head feed rotary valve 6 should be reduced, and the material line should be controlled above the material level meter Ⅱ9; the normal state of the material level meter Ⅲ10 should be able to detect the material. When the material level meter Ⅲ10 cannot detect the material, it means that the material line is too low. At this time, the cooling furnace head feed rotary valve 6 should be controlled to stop and the cooling furnace head feed plug valve 5 should be closed to prevent the gas from entering the cooling furnace along the cooling furnace head feed rotary valve 6.

[0018] When the cooling furnace receiving bin 4 is not unblocked, the cooling furnace receiving bin electric vibrator 7 can be turned on to shake the material down to prevent the material from being bulged.

[0019] The inner diameter of the cooling furnace receiving bin 4 is larger than the inner diameter of the plug valve 3 of the retorting furnace discharge box, so that the material flow is easier and the material is prevented from being expanded.

[0020] In actual use, the material level meter I8, material level meter II9 and material level meter III10 can be connected to the sound and light alarm device or connected to the control system of the factory. When the signal arrives, the sound and light alarm device will be triggered or a prompt will be given in the control system of the factory to provide the factory staff with the opportunity to perform subsequent operations. The automatic control program can also be used for automatic control.
