[0004] The utility model is realized by the following technical solutions:

[0010] Furthermore, a heat recovery device is provided above the discharge hood, and the heat recovery device includes a fan, and the fan is connected to the discharge hood.

[0019] (3) In order to make the multi-channel cooler structure firm and durable and meet the requirements of high-temperature expansion and contraction of the equipment, a cylinder support device is used to connect and fix the inner cylinder, middle cylinder and outer cylinder to make the equipment operation more stable and reliable.

[0027] The cooler 1 includes an inner cylinder 5, a middle cylinder 6 and an outer cylinder 7 which are coaxially rotated from the inside to the outside. In order to meet the requirements of high-temperature materials, the inner cylinder and the middle cylinder can be made of heat-resistant steel or stainless steel.

A plurality of cylinder sliding mechanisms arranged along the circumferential direction are also arranged between the inner cylinder 5 and the middle cylinder 6, and between the middle cylinder 6 and the outer cylinder 7, that is, cylinder sliding mechanisms are welded between the outer wall of the inner cylinder and the inner wall of the middle cylinder, and between the outer wall of the middle cylinder and the inner wall of the outer cylinder, respectively. The cylinder sliding mechanism includes a cylinder sliding support 18, and the cylinder sliding support 18 includes two spaced and vertically arranged clamping plates 1801 and a vertical plate 1802 located between the clamping plates 1801. One end of the clamping plate 1801 is connected to the outer wall of the inner cylinder. The vertical plate 1802 is connected to the inner wall of the middle cylinder, and the other ends of the vertical plate 1802 and the clamping plate 1801 are both suspended, and the suspended end of the vertical plate 1802 extends between the two clamping plates; one end of the clamping plate 1801 can also be connected to the inner wall of the middle cylinder, and the vertical plate 1802 is connected to the outer wall of the inner cylinder; both methods can meet the axial movement of the cylinder after heating, thereby improving the service life of the multi-channel cooler, and the sliding support of the inner cylinder and the middle cylinder sandwich is made of heat-resistant steel or stainless steel.

[0028] The cooler 1 is also provided with a cylinder support device 9, which includes a plurality of connecting rods arranged along the circumferential direction, and the inner cylinder 5, the middle cylinder 6, and the outer cylinder 7 are connected by the connecting rods. When the heated cylinder expands, the inner cylinder 5 and the middle cylinder 6 are telescoped and moved through the gap of the sliding support 18. The cylinder support device is added to fix the inner cylinder and the middle cylinder, so that the operation of the equipment is more stable and reliable.

[0029] The inner walls of the inner cylinder 5, the middle cylinder 6 and the outer cylinder 7 are all provided with material lifting guide plates 8, and the material lifting guide plates 8 include guide plates 801 connected to the inner walls of the corresponding cylinders and arranged obliquely, and material lifting plates 802 connected to the bottom of the guide plates and bent. The material lifting guide plates 8 of the middle cylinder are not inclined in the same direction as the material lifting guide plates 8 of the inner cylinder and the outer cylinder.

[0030] One end of the inner tube 5 extends to the outside of the outer tube 7 and is connected to a feeding mechanism, which includes a high-temperature material chute 15 , one end of which is connected to the inner tube 5 , and the other end of which is connected to a discharge box 17 of a roasting rotary kiln 16 .

[0031] An end of the middle cylinder 6 away from the feeding mechanism forms a middle cylinder receiving end 601 with the inner cylinder, that is, the end of the middle cylinder 6 away from the feeding mechanism is longer than the corresponding end of the inner cylinder; an outer cylinder receiving end 701 is formed between the end of the outer cylinder 7 close to the feeding mechanism and the middle cylinder 6, that is, the end of the outer cylinder 7 close to the feeding mechanism is longer than the corresponding end of the middle cylinder; end baffles are provided at both ends of the outer cylinder 7 and the end away from the feeding mechanism is connected to the discharge cover 4 through the discharge pipe 3; the end of the middle cylinder 6 away from the feeding mechanism is conical, which is convenient for discharge.

[0032] The working process is as follows: the material is driven forward by the rotation of the multi-channel cooler 1 under the action of the lifting guide plate 8, and when it moves to the discharge end of the inner cylinder 5, it falls into the middle cylinder receiving end in the inner cylinder and middle cylinder interlayer. Similarly, the lifting guide plate 8 tilted in the opposite direction is welded inside the middle cylinder 6, so that the material moves to the feeding end of the multi-channel cooler in the inner cylinder and middle cylinder interlayer and then falls into the outer cylinder receiving end in the middle cylinder and outer cylinder interlayer. The lifting guide plate 8 welded inside the outer cylinder 7 makes the material move to the discharge section and enter the discharge cover 4. In summary, the material passes through the inner cylinder, the inner cylinder and middle cylinder interlayer, and the middle cylinder and outer cylinder interlayer respectively, and finally flows out from the discharge cover 4. The discharge temperature can be reduced by 80% compared with the feeding temperature, and the material moves back and forth in the multi-channel cooler, which reduces the length of the equipment and reduces the floor space of the equipment.

[0033] Furthermore, a heat recovery device is also provided above the discharge hood 4, and the heat recovery device includes a fan 14, and the fan 14 is connected to the discharge hood 4. The air enters the discharge hood 4 through the air supply fan 14 and then enters the multi-channel cooler to flow in the opposite direction of the material; the air passes through the interlayer between the outer cylinder and the middle cylinder, the interlayer between the middle cylinder and the inner cylinder, and the inner cylinder respectively, and the air contacts the material in the multi-channel cooler in reverse, which serves the purpose of heat dissipation of the material and heating of the air. The heated air is connected to the inside of the rotary kiln discharge box 17 through the heat exchange flue gas duct 2 and then enters the rotary kiln 16 to provide part of the heat for the rotary kiln calcination, thereby reducing the use of fuel supply required for the rotary kiln roasting heat, reducing energy consumption, and improving economic benefits.
