It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0025] In order to solve the technical problem of low thermal energy utilization rate of ceramsite in the prior art, the utility model provides a ceramsite waste heat utilization device, which can achieve sufficient heat exchange between the material to be heated and the high-temperature ceramsite.

[0027] like Figure 1-3 As shown, an embodiment of the present invention provides a ceramsite waste heat utilization device, which includes:

[0028] An outer cylinder 1 and an inner cylinder 2 are provided, wherein an outer cylinder channel is formed in the outer cylinder 1, an outer cylinder feed port 11 and an outer cylinder discharge port 12 are provided on the outer cylinder 1, and the inner cylinder 2 runs through the outer cylinder channel, an inner cylinder feed port 21 and an inner cylinder discharge port 22 are provided on the inner cylinder 2, wherein the outer cylinder discharge port 12 is higher than the outer cylinder feed port 11, or / and the inner cylinder discharge port 22 is higher than the inner cylinder feed port 21.

[0029] The utility model provides a ceramsite waste heat utilization device, which includes an outer cylinder 1 and an inner cylinder 2. An outer cylinder channel is formed in the outer cylinder 1, an outer cylinder feed port 11 and an outer cylinder discharge port 12 are provided on the outer cylinder 1, and the inner cylinder 2 runs through the outer cylinder channel. An inner cylinder feed port 21 and an inner cylinder discharge port 22 are provided on the inner cylinder 2, wherein the outer cylinder discharge port 12 is higher than the outer cylinder feed port 11, or / and the inner cylinder discharge port 22 is higher than the inner cylinder feed port 21. The material to be heated and the ceramsite are in an "overflow mode" of entering from a low place and being discharged from a high place in the outer cylinder 1 and the inner cylinder 2, which can effectively prolong the contact time between the material to be heated and the high-temperature ceramsite, effectively improve the heat exchange efficiency, and improve the thermal energy utilization rate of the high-temperature ceramsite.

[0030] Specifically, the outer cylinder 1 includes an outer cylinder body 13 and an adjustable bracket 14. The adjustable bracket 14 is fixed to a reliable surface. The adjustable bracket 14 has an adjustable connection end and is fixed to the outer cylinder body 13, which can adjust the inclination angle of the outer cylinder body 13. During use, the inclination angle of the outer cylinder body 13 can be adjusted to adjust the time that the material to be heated and the high-temperature ceramsite stay in the outer cylinder body 13 and the inner cylinder 2.

[0031] Furthermore, the adjustable bracket 14 includes a cylinder 141, which is vertically fixed on a reliable ground. The movable end of the cylinder 141 can be extended and retracted in the vertical direction and is hinged to the outer cylinder 13. When in use, the tilt angle of the outer cylinder 13 is adjusted by extending and retracting the movable end of the cylinder 141.

[0032] Furthermore, a heat recovery pipe 131 is provided within the outer cylinder 13, with the inlet and outlet of the heat recovery pipe 131 located on the outer surface of the outer cylinder 13. During the heat exchange between the high-temperature ceramsite and the heated material, some of the heat energy is inevitably used to heat the outer cylinder 13. The heat recovery pipe 131 can be used to recover some of the heat energy used to heat the outer cylinder 13 for other uses. The provision of the heat recovery pipe 131 can improve the utilization rate of heat energy.

[0033] Furthermore, the inlet of the heat recovery pipe 131 is higher than the outlet, which can extend the contact time between the heat exchange liquid in the heat recovery pipe 131 and the outer cylinder 13, thereby improving the heat energy utilization rate.

[0034] Furthermore, the outer surface of the outer cylinder 13 is wrapped with a heat insulation layer to insulate the outer cylinder 13 from the outside, thereby preventing the heat in the outer cylinder 13 from being dissipated to the outside.

[0035] Specifically, it also includes an outer cylinder transport component 3, which includes a sleeve portion 31, a spiral blade 32, and a rotation drive member 33. The sleeve portion 31 is sleeved on the inner cylinder 2 and is partially located outside the outer cylinder body 13. One end of the spiral blade 32 is fixed to the portion of the sleeve portion 31 located inside the outer cylinder body 13. The spiral blade 32 is spirally arranged around the outer surface of the inner cylinder 2. The rotation drive member 33 is connected to the sleeve portion 31 and is used to drive the sleeve portion 31 to rotate relative to the inner cylinder 2. The sleeve portion 31 is relative to the inner cylinder 2, driving the spiral blade 32 to rotate, which can push the material or ceramsite from the outer cylinder feed port 11 to the outer cylinder discharge port 12 to avoid blockage.

[0036] Furthermore, the spiral blade 32 is provided with a plurality of spreading plates 321. One end of each of the spreading plates 321 is fixed to the spiral blade 32, and the other end of each of the spreading plates 321 is bent into a hook-shaped portion. This arrangement enables the spreading plates 321 to scoop up material at the bottom and rotate it to transport it to the top for spreading. This can prevent material from getting stuck or clogged at the bottom and improve the heat exchange efficiency of the material.

[0037] There are many ways to implement the rotation drive member 33 to drive the sleeve portion 31. In some feasible embodiments, the rotation drive member 33 includes a rotary motor and a belt, the belt being sleeved around the sleeve portion 31 and the rotating end of the rotary motor. The rotating end of the rotary motor rotates, and the sleeve portion 31 is driven by the belt.

[0038] In this embodiment, the rotary drive member 33 includes a rotary motor 331, a gear 332, and a ring gear 333. The ring gear 333 is sleeved on the outer surface of the sleeve portion 31. The gear 332 is fixed to the rotating end of the rotary motor 331 and meshes with the ring gear 333. When the rotating end of the rotary motor 331 rotates, the sleeve portion 31 is driven by the gear 332 and the ring gear 333.

[0039] Specifically, it also includes an inner cylinder transport component 4, which includes a rotating rod 41, a spiral propulsion piece 42 and a drive motor 43. The rotating rod 41 is provided through the outer cylinder body 13 and the inner cylinder 2, with one end located outside the outer cylinder body 13 and the other end located inside the inner cylinder 2. The spiral propulsion piece 42 is axially fixed to the portion of the rotating rod 41 located inside the inner cylinder 2. The drive motor 43 is fixed to the outer cylinder body 13 and coaxially with the rotating rod 41. The drive motor 43 drives the rotating rod 41 to rotate, driving the spiral propulsion piece 42 to rotate, which can push the material or ceramsite from the inner cylinder feed port 21 to the inner cylinder discharge port 22 to avoid blockage.

[0040] In order to better understand the present invention, the following Figures 1 to 3 The technical solution of the utility model is described in detail:

[0041] The material to be heated is introduced into the outer cylinder body 13 from the outer cylinder feed port 11, and the high-temperature ceramsite is introduced from the inner cylinder feed port 21. The rotating drive member 33 drives the sleeve portion 31 to rotate relative to the inner cylinder 2, driving the spiral blade 32 to rotate, and can push the material from the outer cylinder feed port 11 to the outer cylinder discharge port 12; the driving motor 43 drives the rotating rod 41 to rotate, driving the spiral propulsion piece 42 to rotate, and can push the ceramsite from the inner cylinder feed port 21 to the inner cylinder discharge port 22. During the movement, the ceramsite exchanges heat with the material. After the heat exchange is completed, the ceramsite is discharged from the inner cylinder discharge port 22, and the material is discharged from the outer cylinder discharge port 12.
