Description

Technical Field

[0001] The utility model relates to the technical field of preheaters, in particular to a preheater for efficiently heating raw materials. Background Art

[0002] In production, the temperature must reach the melting point of the raw material to decompose the raw material, which causes certain troubles when the rotary kiln calcines the raw material. Therefore, by configuring a preheater, the raw material is preheated so that the temperature of the raw material is close to the melting point before entering the rotary kiln, thereby speeding up the production of clinker in the rotary kiln.

[0003] The existing Chinese utility model patent with reference announcement number: CN219494860U discloses a preheater for efficiently heating raw materials, including a negative pressure control structure capable of controlling negative pressure, wherein a homogenizing heat exchange structure for increasing the heat exchange area of ​​the raw materials is arranged inside the negative pressure control structure, wherein the negative pressure control structure comprises a preheater with a heat exchange tube chamber and a heat exchange chamber inside, and an air lock valve is arranged above the preheater for isolating the flue gas to the heat exchange tube chamber, and a flap valve for uniformly distributing the raw materials is arranged on the air lock valve, and a flue fan for extracting and discharging the flue gas is arranged below the preheater, and a cyclone separator for separating the flue gas is arranged below the flue fan, and a smoke exhaust dust collector is arranged below the air separator, and the homogenizing heat exchange structure comprises an adjusting shaft with a hollow structure inside, and the adjusting shaft is inlaid with a material rod with a material spreading hole on the surface, and the material rod is provided with a vibration disk for preventing dust accumulation through the adjusting shaft, and the preheater for efficiently heating raw materials has an isolation effect on the flue gas through the arranged air lock valve.

[0004] Although the above-mentioned preheater for efficiently heating raw materials solves the problem that the heat exchange time and heat exchange efficiency of the raw materials cannot be maintained during the heat exchange process of the preheater by setting up a negative pressure control structure, the existing preheater has a poor effect on the waste heat of the raw materials, which easily leads to insufficient internal preheating effect of the piled raw materials. Moreover, when the raw materials are added, dust will be mixed in to absorb heat, resulting in unsatisfactory preheating effect, and at the same time affecting the sintering effect of the rotary kiln.

[0026] Specifically, the raw material is fed into the feed hole 11 inside the support box 1 through the feed port 12, and finally fed into the preheating device 23 through the feed hole 11. The motor 13 and the support rod 14 are installed inside the support box 1, and the rotating rod 15 is located inside the feed hole 11. Through the operation of the motor 13, the rotating rod 15 and the stirring rod 16 are driven to rotate and stir the raw material.

[0027] A shell 2 is fixedly mounted on one side of the supporting box 1 , and a bottom plate 21 is fixedly mounted on the bottom of the shell 2 .

[0028] A temperature insulation layer 22 is fixedly installed inside the housing 2 , and a preheating device 23 is fixedly installed inside the temperature insulation layer 22 .

[0029] Nine preheating holes 24 are fixedly installed inside the preheating device 23 , and a discharge pipe 25 is fixedly installed on one side of the outer shell 2 .

[0030] A discharge port 26 is fixedly mounted on one side of the discharge pipe 25 .

[0031] Specifically, the outer shell 2 is protected, the bottom plate 21 supports the whole, the internal temperature is isolated by the thermal insulation layer 22, the raw material is preheated by the nine preheating holes 24 inside the preheating device 23, and the raw material is mixed through the discharge pipe 25 and then sent out from the discharge port 26.

[0032] Two sliding grooves 3 are fixedly installed on the other two sides of the feed port 12 , and sliding blocks 31 are movably connected inside the sliding grooves 3 .

[0033] A rotating shaft 32 is fixedly mounted on one side of the sliding block 31 , and a rotating plate 33 is fixedly mounted on one side of the rotating shaft 32 . The rotating plate 33 is in a “cross” shape.

[0034] Specifically, the sliding block 31 slides inside the sliding groove 3, thereby driving the rotating plate 33 to move left and right, and the rotating shaft 32 rotates, thereby driving the rotating plate 33 to move and rotate, and the raw material accumulated inside the feed port 12 is sent into the feed hole 11.

[0035] A vacuum cleaner 4 is fixedly installed on one side of the feed port 12, two vacuum pipes 41 are fixedly installed on both sides of the vacuum cleaner 4, a vacuum port 42 is fixedly installed on one side of the vacuum pipe 41, an interception net 43 is fixedly installed on one side of the vacuum port 42, and a collection box 44 is fixedly installed at the bottom of the vacuum cleaner 4.

[0036] Specifically, by the operation of the vacuum cleaner 4, the raw material inside the feed port 12 is vacuumed through the two vacuum ports 42. The vacuum ports 42 suck the dust and then send the raw material into the vacuum cleaner 4 from the vacuum pipe 41. Finally, the dust is sent into the collection box 44 through the vacuum cleaner 4 for collection and storage.

[0037] Working principle: First, the shell 2 is supported by the bottom plate 21, and the raw material is added to the inside of the feed port 12. The vacuum cleaner 4 is operated, so that the raw material inside the feed port 12 is vacuumed through the two vacuum ports 42. The vacuum ports 42 suck the dust and then send the raw material into the vacuum cleaner 4 from the vacuum pipe 41. Finally, the vacuum cleaner 4 sends the dust into the collection box 44 for collection and storage. The interception net 43 can intercept the raw material to prevent the vacuum port 42 from sucking the raw material into the inside when vacuuming. The problem of waste is solved, and the practicality of the preheater for efficiently heating raw materials is improved. After the dust is removed, the problem of dust absorbing heat and affecting the heating of raw materials can be avoided. At the same time, the problem of dust entering the rotary kiln and affecting the sintering effect can be avoided. The raw materials enter the nine feeding holes 11 inside the supporting box 1 from the feeding port 12, and slide back and forth in the two sliding grooves 3 through the two sliding blocks 31, thereby driving the rotating plate 33 to move left and right, and the rotating shaft 32 rotates, thereby driving the rotating plate 33 to move and rotate at the same time. The raw material accumulated on the top of the support box 1 is pushed into the feed hole 11, thereby avoiding the problem of raw material accumulation on the top of the support box 1. The raw material is fed into the nine preheating holes 24 in the preheating device 23 through the feed hole 11. The raw material is preheated by the nine preheating holes 24, thereby increasing the contact area between the raw material and the preheating device 23, and improving the heating effect of the preheater for efficiently heating the raw material. The operation of the motor 13 drives the rotating rod 15 to rotate, so that the stirring rod 16 follows The preheating hole 24 is tilted so that the raw material can automatically move to the other side. The stirring rod 16 rotates so that the raw material can be turned over, thereby evenly heating the raw material, thereby increasing the heating effect of the preheater for efficiently heating the raw material. The preheating device 23 is insulated by the insulation layer 22, and the outer side is protected and supported by the outer shell 2. The heated raw material is mixed inside the discharge pipe 25 and then sent out from the discharge port 26.
