Description

Technical Field

[0001] The invention belongs to the technical field of drying equipment, and in particular relates to raw material drying equipment and a drying method for processing lightweight building materials. Background Art

[0002] During the production and processing of building materials, it is usually necessary to pre-treat the raw materials. In the case that some raw materials have high humidity, in order to ensure good and stable processing results, the raw materials usually need to be placed in drying equipment for drying.

[0003] The current raw material drying equipment for processing lightweight building materials usually places the raw materials to be dried in a drying box for static use, and starts the heating equipment in the drying box. The internal high temperature is used to evaporate the moisture on the surface and inside of the raw materials into wet steam, and the drying and dehumidification are completed after the steam is discharged. The current way to improve the drying efficiency of raw materials is usually to add a hollow roller in the drying box, and drive the motor to rotate the roller so that the raw materials rotate in the roller to achieve effective drying of the outer surface of the raw materials. However, the actual drying efficiency is not significantly improved. When the raw materials rotate in the roller, they are always accumulated at the bottom due to gravity. Although the outer surface of some materials can be effectively heated and dried, due to the stacking effect, some materials are squeezed at the bottom and need to be fully heated under the effect of repeated rotation. The actual drying effect is not good.

[0004] In addition, since the heating tube is fixedly installed on the inner surface of the drying box in the current drying box, the materials actually being rotated for drying are concentrated in the roller in the middle of the drying box. From the time the raw materials are placed in the roller and the heating tube is started for heating, the temperature near the heating tube rises rapidly and gradually radiates toward the middle. The actual initial drying efficiency is low during drying, and it takes a certain amount of time to wait for the heat to radiate into the middle roller. The drying efficiency of the raw materials is low during the initial drying process, and the actual temperature rise uniformity of the raw materials is poor when there is external-to-inward radiation, which reduces the actual drying efficiency. Summary of the invention

[0006] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions: a raw material drying equipment and drying method for processing lightweight building materials, comprising a base, wherein the top surface of the base is respectively provided with a first box and a second box, the inner surfaces of the first box and the second box are fixedly installed with mounting rods, the interior of the mounting rods is provided with a mounting cavity, the interior of the mounting cavity is provided with a pumping mechanism, the outer surface of the mounting rods is fixedly connected with a curved pipe, the end surface of the curved pipe is fixedly connected with an air outlet plate, the bottom surface of the air outlet plate and the outer surface of the mounting rods are provided with air outlet holes, and the outer surfaces of the two mounting rods are fixedly connected with a curved pipe. The surfaces are movably sleeved with mounting rings, the outer surfaces of the two mounting rings are fixedly connected with mounting plates, the sides of the mounting plates are fixedly connected with rolling mechanisms, the outer surface of one mounting ring is fixedly sleeved with gear one, the end face of box No. 1 is fixedly mounted with a motor, the output shaft of the motor is fixedly connected with a rotating shaft, the outer surface of the rotating shaft is fixedly sleeved with gear two, the gear one is meshingly connected with gear two, there are two rolling mechanisms, the outer surface of the mounting rod is fixedly sleeved with a distribution ring, and the inner surfaces of boxes No. 1 and No. 2 are fixedly mounted with heating tubes.

On the upper and lower sides, part of the raw materials are located in the reserved grooves, and as the rolling mechanism rotates, the raw materials inside keep changing their positions. As the heating tubes in box No. 1 and box No. 2 heat up, the two sets of air pumping mechanisms are started, so that the hot air in box No. 1 and box No. 2 is sucked into the distribution ring through the suction hole, and sucked in through the suction pipe and blown out along the outlet pipe, so that the hot air passes into the installation cavity through the air pumping mechanism, and part of the hot air filled into the installation cavity enters the air outlet plate along the curved pipe, so that the air outlet holes on the top surface of the air outlet plate and the air outlet holes on the outer surface of the installation rod blow toward the raw materials from both inside and outside. The internal temperature of box No. 1 and box No. 2 is relatively uniform, and the temperature difference between the center and the two sides is small. The surface temperature of the raw materials rises rapidly, and water vapor is generated rapidly upward.

[0008] Firstly, by making the two groups of rolling mechanisms symmetrically distributed and connected together, and making the rolling mechanism a combination of an outer cylinder and an inner cylinder, and setting a reserved groove on the outer surface of the inner cylinder, it is possible to effectively avoid the raw materials from being piled up underneath during rotation and rolling, and temporarily store part of the raw materials in the reserved groove to increase the exposed area of ​​the raw materials, and cooperate with the air pump mechanism to suck the hot air inside the No. 1 box and the No. 2 box into the inside of the mounting rod, and realize the hot air blowing on both sides of the rolling mechanism through the air outlet plates on the outside of the rolling mechanism and the mounting rod located inside the rolling mechanism, so as to avoid the accumulation of raw materials and effectively utilize the wind force provided by the inside and outside, thereby greatly increasing the evaporation area and evaporation speed, and adopting the internal circulating hot air method to avoid the use of outside air to accelerate the evaporation of raw materials, thereby improving the drying efficiency of the raw materials, and ensuring the internal temperature to be stable during drying and dehumidification, and having a good use effect.

[0009] In addition, by fixing a distribution ring on the outer surface of the mounting rod and opening a suction hole on the outer surface of the distribution ring, at the beginning stage of heating by the heating tube, when the raw materials are initially dried, the initial hot air near the heating tube is sucked into the mounting rod from both sides by means of the annularly distributed suction holes in cooperation with the air pump mechanism, and is blown toward the raw materials by means of the air outlet holes, so as to avoid the heating tubes on both sides gradually radiating heat, thereby greatly improving the heating efficiency of the raw materials during initial drying, and allowing the high-temperature air in the middle and outer sides of boxes No. 1 and No. 2 to quickly diffuse and radiate to the middle, thereby improving the temperature uniformity inside boxes No. 1 and No. 2, and thus improving the drying efficiency of the raw materials.

The inner surface of the retaining groove is movably connected to the retaining ring.

The fixing sleeve is fixedly connected to the end face of the air outlet pipe. The through hole and the circular hole are both provided on the front side of the fixing sleeve. The through hole and the circular hole are both provided on the front side of the fixing sleeve. The fixing sleeve is located on the outside of the curved pipe to ensure that part of the air volume is effectively blown into the curved pipe.

[0013] Preferably, the outer surface of the distribution ring is provided with suction holes, and the interior of the distribution ring is connected with the suction pipe. The annularly distributed suction holes inhale air from four directions of up, down, left and right, so that the air in the high temperature area of ​​the heating tube is inhaled, thereby improving the heat radiation efficiency, improving the internal temperature uniformity, and improving the efficiency of initial drying.

[0014] Preferably, an annular groove is provided on the outer surface of the mounting rod, a fixing ring is fixedly sleeved on the inner surface of the mounting ring, and the outer surface of the fixing ring is movably sleeved with the annular groove. The movably sleeved connection between the annular groove and the fixing ring ensures that the mounting ring has stable rotation and avoids left and right lateral movement.

[0015] Preferably, the inner surface of the circular hole is movably connected to the adjustment mechanism, and the adjustment mechanism includes an adjustment tube and a sealing sleeve. The diameter of the sealing sleeve is smaller than the inner diameter of the through hole, ensuring that the sealing sleeve can be mounted in the through hole and seal the through hole, thereby allowing the air sucked in the intake pipe to pass into the adjustment mechanism.

[0016] Preferably, a sleeve hole is provided on the end face of the mounting rod, and the inner surface of the sleeve hole is movably connected to the adjusting tube. The sleeve hole and the adjusting tube are movably connected to each other, so that the adjusting tube is easy to rotate and pull, and the outer ends of the two groups of adjusting tubes pass through box No. 1 and box No. 2 respectively, ensuring that they have sufficient length for operation from the outside.

[0018] Second embodiment: Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 Fig. 9As shown, when it is necessary to discharge water vapor, the regulating mechanism is rotated so that the regulating tube of the regulating mechanism drives the sealing sleeve to rotate slowly upward, and at the same time, a pulling force is applied outward, so that when the sealing sleeve rotates to the through hole, the sealing sleeve is inserted into the through hole, so that the through hole is sealed, and at this time, the No. 2 box is gently pushed outward, so that there is a gap between the No. 1 box and the No. 2 box, and at the same time, the clamping ring is kept in the clamping groove to ensure that the two sets of rolling mechanisms continue to rotate, so that the air mixed with water vapor in the No. 1 box and the No. 2 box is sucked in through the distribution ring, and the air mixed with water vapor is discharged through the regulating tube of the regulating mechanism by using the sleeved sealing sleeve, and the outside air is replenished from the gap between the No. 1 box and the No. 2 box to stabilize the internal air pressure; after the drying is completed, the heating tube is turned off, so that a certain gap is maintained between the No. 1 box and the No. 2 box to allow the outside air to be sucked in, and the rolling mechanism continues to rotate. The mechanism rotates, keeping the sealing sleeve of the regulating mechanism in the through hole, keeping the air pump mechanism started, and the outside cold air is sucked in along the four-side gaps of box No. 1 and box No. 2, and the hot air inside box No. 1 and box No. 2 is sucked in through the distribution ring and discharged through the regulating mechanism, and the internal temperature of box No. 1 and box No. 2 drops rapidly. When the internal temperature of box No. 1 and box No. 2 drops to normal temperature, the regulating mechanism is pushed to move the sealing sleeve out of the through hole. At this time, the distribution ring sucks the normal temperature air into the air pump mechanism, and blows the normal temperature air into the installation cavity through the air pump mechanism. Part of the normal temperature air in the installation cavity enters the curved pipe, so that the air outlet holes on the outside of the installation rod and the air outlet holes on the bottom of the air outlet plate are blown from the inside and outside to the raw materials in the rolling mechanism. As the raw materials rotate and are subjected to wind from both inside and outside, the raw materials in the rolling mechanism cool down rapidly.

[0019] Firstly, by pushing box No. 1 and box No. 2 apart by a certain distance, a gap is maintained between box No. 1 and box No. 2, while the two sets of rolling mechanisms are ensured to rotate, and the adjusting mechanism is operated in coordination, so that the sealing sleeve of the adjusting mechanism is inserted into the through hole of the pumping mechanism, so that the air mixed with water vapor inside box No. 1 and box No. 2 is sucked in through the pumping mechanism and passed into the adjusting mechanism, so that wet steam is discharged, and the amount of wet steam is reduced during internal drying, thereby improving the drying effect of the raw materials, and after drying, the heat is first discharged by operating the adjusting mechanism, and the air outlet direction of the pumping mechanism is changed after the heat is quickly discharged, and the normal temperature air is blown back to the rotating raw materials, and the internal environment temperature is quickly lowered and the raw materials are cooled separately, thereby greatly improving the cooling of the raw materials after drying, improving the efficiency of subsequent transfer and transportation, reducing the cooling waiting time, and achieving good use effect.

[0020] A method for drying raw materials for processing lightweight building materials comprises the following steps:

[0021] Step 1: Keep box 1 and box 2 separated, place the raw materials to be dried in two sets of rolling mechanisms, and ensure that the raw materials are located between the outer cylinder and the inner cylinder in the rolling mechanism, and push box 1 and box 2 closer;

[0022] Step 2: Start the heating tube and turn on the motor, so that gear 1 drives a group of mounting rings to rotate, and the mounting rings drive a group of rolling mechanisms on the side of the mounting plate to rotate, so that the two groups of rolling mechanisms rotate at the same time. As the heating tubes in the No. 1 box and the No. 2 box heat up, start the air pump mechanism, so that the hot air in the No. 1 box and the No. 2 box is sucked into the distribution ring, so that the hot air passes into the mounting cavity through the air pump mechanism, and part of the hot air enters the air outlet plate along the curved pipe, so that the air outlet holes on the top surface of the air outlet plate and the air outlet holes on the outer surface of the mounting rod blow toward the raw materials from both inside and outside.

[0023] Step 3: When it is necessary to discharge water vapor, rotate the regulating mechanism so that the regulating tube of the regulating mechanism drives the sealing sleeve to rotate to the through hole, so that the sealing sleeve is inserted into the through hole, and the No. 2 box is gently pushed outward, while keeping the clamping ring sleeved in the clamping groove, so that the air mixed with water vapor in the No. 1 box and the No. 2 box is sucked in through the distribution ring, discharged through the regulating tube of the regulating mechanism, and supplemented from the outside through the gap between the No. 1 box and the No. 2 box;

[0024] Step 4: After drying, turn off the heating tube to keep a certain gap between box No. 1 and box No. 2, continue to rotate the rolling mechanism, keep the sealing sleeve of the adjustment mechanism in the through hole, and the outside cold air is sucked in along the four-sided gaps of box No. 1 and box No. 2, and the hot air inside box No. 1 and box No. 2 is sucked in through the distribution ring and discharged through the adjustment mechanism. When the internal temperature of box No. 1 and box No. 2 drops to normal temperature, the sealing sleeve is removed from the through hole. At this time, normal temperature air blows from the inside and outside through the air outlet to the raw materials in the rolling mechanism, and the raw materials cool down rapidly.

[0025] The beneficial effects of the present invention are as follows:

[0026] 1. The present invention makes two groups of rolling mechanisms symmetrically distributed and connected together, and makes the rolling mechanism composed of an outer cylinder and an inner cylinder, and makes a reserved groove on the outer surface of the inner cylinder, so that the raw materials are effectively prevented from being piled up below during rotation and rolling, and the reserved groove is used to temporarily store part of the raw materials to increase the exposed area of ​​the raw materials, and the pumping mechanism is used to suck the hot air inside the first box and the second box into the inside of the mounting rod, and the hot air is blown on both sides of the rolling mechanism through the air outlet plates on the outside of the rolling mechanism and the mounting rod located inside the rolling mechanism, so as to avoid the accumulation of raw materials and effectively use the wind force provided by the inside and outside, thereby greatly improving the evaporation area and evaporation speed, and adopting the internal circulation hot air mode to avoid the use of the outside air to accelerate the evaporation of the raw materials, thereby improving the drying efficiency of the raw materials, and ensuring the internal temperature to be stable during drying and dehumidification, and having a good use effect.

[0027] 2. The present invention fixes a distribution ring on the outer surface of the installation rod, and opens a suction hole on the outer surface of the distribution ring. When the raw materials are initially dried at the beginning of the heating of the heating tube, the initial hot air near the heating tube is sucked into the installation rod from both sides by means of the annularly distributed suction holes in cooperation with the air pump mechanism, and is blown toward the raw materials by means of the air outlet holes, so as to avoid the heating tubes on both sides gradually radiating heat, thereby greatly improving the heating efficiency of the raw materials during the initial drying, and allowing the high-temperature air in the middle and outer sides of the No. 1 box and the No. 2 box to quickly diffuse and radiate to the middle, thereby improving the temperature uniformity inside the No. 1 box and the No. 2 box, thereby improving the drying efficiency of the raw materials.

[0028] 3. The present invention pushes box No. 1 and box No. 2 apart by a certain distance so that a gap is maintained between them, while ensuring the rotation of the two sets of rolling mechanisms, and cooperates with the operation of the adjusting mechanism so that the sealing sleeve of the adjusting mechanism is inserted into the through hole of the air pumping mechanism, so that the air mixed with water vapor inside box No. 1 and box No. 2 is sucked in through the air pumping mechanism and passed into the adjusting mechanism, so that wet steam is discharged, ensuring the reduction of wet steam during internal drying, thereby improving the drying effect of raw materials, and after drying is completed, heat is first discharged by operating the adjusting mechanism, and after the heat is quickly discharged, the air outlet direction of the air pumping mechanism is changed, and normal temperature air is blown back to the rotating raw materials, and the internal environment temperature is quickly lowered and the raw materials are cooled separately, thereby greatly improving the cooling of the raw materials after drying, improving the efficiency of subsequent transfer and transportation, reducing the waiting time for cooling, and achieving good use effect.

[0042] Firstly, by making the two groups of rolling mechanisms 12 symmetrically distributed and connected together, and making the rolling mechanism 12 a combination of an outer cylinder 122 and an inner cylinder 123, and setting a reserved groove 124 on the outer surface of the inner cylinder 123, it is possible to effectively avoid the raw materials from being piled up underneath during rotation and rolling, and to temporarily store part of the raw materials in the reserved groove 124 to increase the exposed area of ​​the raw materials, and to cooperate with the air pump mechanism 6 to suck the hot air inside the No. 1 box 2 and the No. 2 box 3 into the interior of the mounting rod 4, and to realize the hot air blowing on both sides of the rolling mechanism 12 through the air outlet plates 8 on the outside of the rolling mechanism 12 and the mounting rod 4 located inside the rolling mechanism 12, so as to avoid the accumulation of raw materials and effectively utilize the wind force provided by both sides, thereby greatly increasing the evaporation area and evaporation speed, and to adopt the internal circulating hot air method to avoid the use of the outside air to accelerate the evaporation of raw materials, thereby improving the drying efficiency of the raw materials, and ensuring the internal temperature to be stable during drying and dehumidification, and having a good use effect.

The annularly distributed suction holes 20 inhale air from four directions of up, down, left and right, so that the air in the high temperature area of ​​the heating tube 25 is inhaled, thereby improving the heat radiation efficiency, improving the internal temperature uniformity, and improving the efficiency of initial drying.

[0048] Among them, an annular groove 23 is opened on the outer surface of the mounting rod 4, and a fixing ring 24 is fixedly sleeved on the inner surface of the mounting ring 10. The outer surface of the fixing ring 24 is movably sleeved with the annular groove 23. The movably sleeved connection between the annular groove 23 and the fixing ring 24 ensures that the mounting ring 10 has stable rotation and avoids left and right lateral movement.

[0049] Among them, the inner surface of the circular hole 66 is movably connected with the adjustment mechanism 21, and the adjustment mechanism 21 includes an adjustment tube 211 and a sealing sleeve 212. The diameter of the sealing sleeve 212 is smaller than the inner diameter of the through hole 65, ensuring that the sealing sleeve 212 can be sleeved in the through hole 65 and realize the sealing of the through hole 65, so as to realize the air sucked in the intake pipe 62 to pass into the adjustment mechanism 21.

[0050] Among them, a sleeve hole 22 is opened on the end face of the mounting rod 4, and the inner surface of the sleeve hole 22 is movably connected with the adjusting tube 211. The sleeve hole 22 is movably connected with the adjusting tube 211, so that the adjusting tube 211 is easy to rotate and pull, and the outer ends of the two groups of adjusting tubes 211 pass through box No. 1 2 and box No. 2 3 respectively, ensuring that they have sufficient length for operation from the outside.

[0051] Among them, the bottom surfaces of box No. 1 2 and box No. 2 3 are fixedly connected with slide plates 26, and the top surface of the base 1 is fixedly installed with guide rails 27. The inner surface of the guide rails 27 is movably connected with the slide plates 26. The position between box No. 1 2 and box No. 2 3 is easy to adjust by utilizing the movably connected guide rails 27 and slide plates 26.

[0052] Second embodiment: Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 Fig. 9As shown, when it is necessary to discharge water vapor, the regulating mechanism 21 is rotated so that the regulating tube 211 of the regulating mechanism 21 drives the sealing sleeve 212 to rotate slowly upward, and at the same time, a pulling force is applied outward so that when the sealing sleeve 212 rotates to the through hole 65, the sealing sleeve 212 is inserted into the through hole 65, so that the through hole 65 is sealed. At this time, the No. 2 box 3 is gently pushed outward so that there is a gap between the No. 1 box 2 and the No. 2 box 3. At the same time, the clamping ring 13 is kept sleeved in the clamping groove 14 to ensure that the two sets of rolling mechanisms 12 continue to rotate, so that the air mixed with water vapor in the No. 1 box 2 and the No. 2 box 3 is sucked in through the distribution ring 19, and the sleeved sealing sleeve 212 is used to make the air mixed with water vapor discharged through the regulating tube 211 of the regulating mechanism 21, and the outside air is supplemented from the gap between the No. 1 box 2 and the No. 2 box 3 to stabilize the internal air pressure; after drying is completed, the heating tube 25 is closed so that the No. 1 box 2 and the No. 2 box 3 maintain a certain gap to allow the outside air to be sucked in, and continue to make The rolling mechanism 12 rotates, keeping the sealing sleeve 212 of the regulating mechanism 21 in the through hole 65, keeping the air pumping mechanism 6 started, and the outside cold air is sucked in along the four-sided gaps of box No. 1 2 and box No. 2 3. The hot air inside box No. 1 and box No. 2 3 is sucked in through the distribution ring 19 and then discharged through the regulating mechanism 21. The internal temperature of box No. 1 and box No. 2 3 drops rapidly. When the internal temperature of box No. 1 and box No. 2 3 drops to normal temperature, the regulating mechanism 21 is pushed to make the sealing sleeve 212 move out of the through hole 65. At this time, the distribution ring 19 sucks the normal temperature air into the air pumping mechanism 6, and blows the normal temperature air into the installation cavity 5 through the air pumping mechanism 6. Part of the normal temperature air located in the installation cavity 5 enters the curved pipe 7, so that the air outlet 9 on the outside of the installation rod 4 and the air outlet 9 on the bottom of the air outlet plate 8 are blown from the inside and outside to the raw materials in the rolling mechanism 12. As the raw materials rotate and are subjected to wind from both inside and outside, the raw materials in the rolling mechanism 12 cool down rapidly.

[0053] Firstly, by pushing box No. 1 2 and box No. 2 3 apart by a certain distance, a gap is maintained between box No. 1 2 and box No. 2 3, while the two sets of rolling mechanisms 12 are ensured to rotate, and the adjusting mechanism 21 is operated in cooperation, so that the sealing sleeve 212 of the adjusting mechanism 21 is inserted into the through hole 65 of the air pumping mechanism 6, so that the air mixed with water vapor inside box No. 1 2 and box No. 2 3 is sucked in through the air pumping mechanism 6 and passed into the adjusting mechanism 21, so that the wet steam is discharged, and the amount of wet steam is reduced during internal drying, thereby improving the drying effect of the raw materials, and after drying is completed, the heat is first discharged by operating the adjusting mechanism 21, and the air outlet direction of the air pumping mechanism 6 is changed after the heat is quickly discharged, and the normal temperature air is blown back to the rotating raw materials, and the internal environment temperature is quickly lowered and the raw materials are cooled separately, thereby greatly improving the cooling of the raw materials after drying, improving the efficiency of subsequent transfer and transportation, reducing the cooling waiting time, and achieving good use effect.

[0054] A method for drying raw materials for processing lightweight building materials comprises the following steps:

[0055] Step 1: Keep the No. 1 box 2 and the No. 2 box 3 separated, place the raw materials to be dried in two sets of rolling mechanisms 12, and ensure that the raw materials are located between the outer cylinder 122 and the inner cylinder 123 in the rolling mechanism 12, and push the No. 1 box 2 and the No. 2 box 3 closer;

[0056] Step 2: Start the heating tube 25 and turn on the motor 18, so that the gear 15 drives a group of mounting rings 10 to rotate, so that the mounting ring 10 drives a group of rolling mechanisms 12 on the side of the mounting plate 11 to rotate, so that the two groups of rolling mechanisms 12 rotate at the same time, and as the heating tubes 25 in the No. 1 box 2 and the No. 2 box 3 heat up, start the pumping mechanism 6, so that the hot air in the No. 1 box 2 and the No. 2 box 3 is sucked into the distribution ring 19, so that the hot air passes into the mounting cavity 5 through the pumping mechanism 6, and part of the hot air enters the air outlet plate 8 along the curved pipe 7, so that the air outlet 9 on the top surface of the air outlet plate 8 and the air outlet 9 on the outer surface of the mounting rod 4 blow toward the raw materials from both inside and outside;

[0057] Step 3: When it is necessary to discharge water vapor, the regulating mechanism 21 is rotated so that the regulating tube 211 of the regulating mechanism 21 drives the sealing sleeve 212 to rotate to the through hole 65, so that the sealing sleeve 212 is inserted into the through hole 65, and the No. 2 box 3 is gently pushed outward, while the clamping ring 13 is kept sleeved in the clamping groove 14, so that the air mixed with water vapor in the No. 1 box 2 and the No. 2 box 3 is sucked in through the distribution ring 19, and discharged through the regulating tube 211 of the regulating mechanism 21, and the outside world is replenished from the gap between the No. 1 box 2 and the No. 2 box 3;

[0058] Step 4: After drying is completed, close the heating tube 25 to keep a certain gap between box No. 1 2 and box No. 2 3, continue to rotate the rolling mechanism 12, keep the sealing sleeve 212 of the adjusting mechanism 21 in the through hole 65, and the external cold air is sucked in along the four-sided gaps of box No. 1 2 and box No. 2 3, and the hot air inside box No. 1 2 and box No. 2 3 is sucked in through the distribution ring 19 and then discharged through the adjusting mechanism 21. When the internal temperature of box No. 1 2 and box No. 2 3 drops to room temperature, the sealing sleeve 212 is removed from the through hole 65. At this time, the room temperature air is blown from the inside and outside through the air outlet 9 to the raw materials in the rolling mechanism 12, and the raw materials are rapidly cooled.
