Specific implementation mode

[0022] The present utility model provides a raw material recovery structure. To make the purpose, technical solution and effect of the present utility model clearer and more definite, the following further details the present utility model with reference to the attached drawings and by way of examples. It should be understood that the specific examples described herein are only used to explain the present utility model and are not used to limit the protection scope of the present utility model.

[0023] Please refer to Figure 1 and Figure 2 The present utility model provides a raw material recovery structure, including a feed pipe 1 communicated with a material cylinder, a cover body 2 connected to the discharge port of the feed pipe 1, a negative pressure generator 3 arranged in the cover body 2 and used to make the cover body 2 and the feed pipe 1 in a negative pressure state, an atomizer arranged in the cover body 2 and used to spray atomized water into the inner cavity of the cover body 2, and a return pipe 5 communicated with the cover body 2; the return pipe 5 is located downstream of the feed pipe 1, and the discharge port of the return pipe 5 is communicated with the material cylinder.

[0024] In practical applications, when various raw materials are fed into the material cylinder, the flying raw materials are captured by the feed pipe 1 in a negative pressure state and enter the interior of the feed pipe 1 until they enter the interior of the cover body 2. The atomizer located inside the cover body 2 continuously sprays atomized water into the inner cavity of the cover body 2. After the water mist contacts the flying raw materials, the raw materials become heavier and thus fall freely into the return pipe 5 and are directly recycled into the material cylinder through the return pipe 5. Since water is also needed when preparing coal water slurry, the water mist entraining the recycled raw materials becomes an aqueous solution and can also be used as a part of the raw materials for batching. The above structure can directly feed the recycled raw materials, eliminating the cost and trouble of additionally setting up special recycling equipment.

[0025] In some embodiments, the atomizer includes a water pipe 4 with one end communicating with the top of the cover 2 and the other end communicating with a water tank, a water pump (not shown in the figure) disposed on the water pipe 4, and an atomizing nozzle (not shown in the figure) communicating with the end of the water pipe 4 extending into the interior of the cover 2. Specifically, the water in the water tank is one of the raw materials of various raw materials. The water is pumped into the water pipe 4 by the water pump as a power source and atomized by the atomizing nozzle, so that the inner cavity of the cover 2 is filled with water mist, facilitating full contact with the flying raw materials.

The motor 31 located outside the cover 2 rotates, driving the fan 32 located inside the cover 2 to rotate, thereby changing the air pressure inside the cover 2. The setting of the bearing 21 is used to tightly connect with the output end of the motor 31 to avoid affecting the air pressure inside the cover 2.
