[0029] The following will refer to the attached Figures 1 to 6 The utility model is described in detail in conjunction with the embodiments.

[0030] In general, the utility model relates to a feeder defrosting device, which is used to prevent raw coal from freezing in a feeder hopper 1. The device comprises a hopper 1, vertical poles 2 symmetrically arranged on both sides of the hopper 1, an upper connecting rod 202 fixedly arranged on the top of the vertical pole 2, and a defrosting assembly arranged at the end of the upper connecting rod 202, wherein the defrosting assembly is above the hopper 1 and is opposite to the hopper 1;

[0031] In this embodiment, the hopper 1 is a container for storing raw coal of the feeder, and the vertical rod 2 and the upper connecting rod 202 are connected to form a 7-shaped shape, which is used to support the defrosting assembly above the hopper 1, and the lower part of the defrosting device enters the hopper 1 to defrost the frozen coal. In addition, by symmetrically setting the vertical rods 2, the defrosting assembly is also symmetrically set in two groups, which increases the defrosting efficiency of the frozen coal in the hopper 1.

[0032] Among them, Figures 1 to 3 As shown, the defrosting component includes a motor 3 connected to the upper connecting rod 202 through a rotating component, a heating component connected to the end of the motor 3, and a spiral rotating sheet arranged on the outer side wall of the heating component, and the end of the motor 3 is arranged downward.

[0033] In specific implementation, the motor 3 is rotated to drive the heating component to rotate, so that the spiral blade 305 breaks the frozen coal. Before the raw coal is placed in the hopper 1, the defreezing device needs to be set up so that the defreezing component enters the hopper 1. Then the raw coal is placed in and the defreezing component is buried. It should be noted that, as a preferred embodiment, the upper connecting rod 202 can be set as a sliding connection at the top of the vertical rod 2, and the position of the upper connecting rod 202 on the vertical rod 2 is adjusted to drive the defreezing component to adjust up and down.

[0034] like Figure 2 As shown, as a preferred structure, a conical tip portion 306 is fixedly disposed at the bottom end of the outer cylinder 303, and the tip portion 306 is arranged with its top facing downward. Such a structure is conducive to the rotation of the defrosting assembly in the raw coal.

[0035] Among them, Figure 3 As shown, the above-mentioned heating component assembly includes an outer cylinder 303, a mounting groove 307 is arranged in the outer cylinder 303, a heating rod 308 is arranged in the mounting groove 307, and a top cover 304 is arranged on the top of the outer cylinder 303, and the top cover 304 is fixedly connected to the end of the motor 3.

[0036] It should be further explained that the top cover 304 is connected to the outer cylinder 303 by screws, so that the heating rod 308 can be quickly replaced. The heating rod 308 is a remote-controlled heating rod 308, and the heating rod 308 is started when defrosting is required. When the defrosting hopper 1 is not required for unloading, the motor 3 can also be started to facilitate the unloading of raw coal.

[0037] Among them, Figure 1 As shown, the above-mentioned rotating assembly includes a rotating shaft 302 and a mounting plate 301 , one end of the rotating shaft 302 is fixedly connected to the side wall of the upper connecting rod 202 , and the other end is rotatably connected to the side wall of the mounting plate 301 , and the motor 3 is fixedly arranged on the mounting plate 301 .

[0038] The angle of the defrosting assembly in the hopper 1 can be adjusted by rotating the rotating shaft 302, and after adjustment, the angle can be fixed by screws.

[0039] In order to facilitate the stability of the symmetrically arranged upright poles 2, in this embodiment, Figure 1 As shown, the vertical poles 2 on both sides are fixedly connected by a door-shaped fixing rod 203. The fixing rod 203 is door-shaped, which will not affect the feeding of the hopper 1, and can also play a role in connecting and fixing the vertical poles 2.

[0040] It should be noted that, in order to increase the defrosting effect in the hopper 1, in this embodiment, Figure 4 As shown, the inner wall of the hopper 1 is fixedly provided with a mounting wall 4 that follows the contour of the inner wall, and the top of the mounting wall 4 is provided with an inner groove 401 extending downward, and a thermoelectric wire 402 is wound in the mounting groove 307. After the raw coal enters the hopper 1, it will enter the mounting wall 4, and the thermoelectric wire 402 heats the frozen raw coal, and combined with the defrosting device, the raw coal is quickly thawed.

[0041] In order to prevent freezing at the outlet of the hopper 1, in this embodiment, Figure 5 and Figure 6 As shown, a plurality of heating tubes 5 are arranged at intervals along the vertical direction on the inner side wall of the bottom outlet of the hopper 1. The heating tubes 5 follow the contour of the inner side wall of the bottom outlet of the hopper 1. The heating tubes 5 are connected through a connecting pipe 501. The top heating tube 5 is connected to a liquid inlet pipe 502, and the bottom heating tube 5 is connected to a liquid outlet pipe 503. The liquid outlet pipe 503 and the liquid inlet pipe 502 pass through the outside of the hopper 1 and are connected to a water pump to pump circulating ammonia water into the heating tube 5 through the water pump. Circulating ammonia water refers to nitrogen water that is condensed in the coke oven gas primary cooling system and then sent back to the coke oven gas collecting pipe for spraying and cooling the raw gas. The recycled circulating ammonia water carries heat. By using circulating ammonia water, energy consumption is reduced and energy utilization efficiency is improved.

[0042] In addition, in order to further speed up the defrosting of frozen coal at the outlet, Figure 1 As shown, a lower connecting rod 201 is fixedly provided at the lower position of the vertical rod 2, and a drill 6 is provided on the top surface of the lower connecting rod 201, with the end of the drill 6 facing the opening. The drill 6 is started to break the frozen coal at the outlet for thawing.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
