Description

TECHNICAL FIELD

[0001] The application relates to the technical field of ceramic particle processing, in particular to a circulating cooling system for ceramic particle processing and a cooling method. BACKGROUND

[0002] Ceramic particles are made of various clays, slates, shales, coal gangues and industrial solid wastes, etc. by ceramic sintering. The ceramic particles are generally used to replace gravel and pebbles in concrete. The ceramic particle sand has many advantages such as low density, excellent heat preservation and insulation, excellent impermeability, excellent alkali aggregate reactivity, low water absorption, good frost resistance and durability, etc.

[0003] In the production process of ceramic particles, the sintered ceramic particles need to be cooled. The ceramic particles are usually sent into a cooling box through a conveying belt for air cooling treatment to accelerate heat dissipation of the ceramic particles.

[0004] However, in the existing air cooling process of ceramic particles, the cooling effect of the ceramic particles is not uniform, and the uneven cooling of the surface of the ceramic particles will cause the ceramic particles to break due to different cooling and heating shrinkage, so it is difficult to ensure the integrity of the ceramic particles, and thus it is difficult to meet the requirements of the ceramic particle processing process. SUMMARY

[0005] The application provides a circulating cooling system for ceramic particle processing and a cooling method, which can effectively improve the cooling effect and uniformity of the ceramic particles, thereby effectively improving the quality of the cooled ceramic particles, and effectively reducing the energy consumption of the ceramic particle cooling process, and being more green and environmentally friendly.

[0006] In one aspect, the application provides a circulating cooling system for ceramic particle processing, which adopts the following technical scheme:

[0007] A circulating cooling system for ceramic particle processing, comprising a machine body, a conveying device and a cooling device for cooling sintered ceramic particles;

[0008] The conveying device comprises a conveying belt and a first driving member;

[0009] The conveying belt is uniformly provided with a plurality of air holes, the first driving member is used to drive the conveying belt to move relative to the machine body, and the moving direction of the conveying belt is perpendicular to the width direction of the machine body;

[0010] The cooling device comprises a cooling box, a plurality of air coolers and an auxiliary assembly for assisting uniform cooling of the ceramic particles;

[0011] The cooling box is located on the top of the machine body, and has a cooling space inside. A heat dissipation vent communicating with the cooling space is opened on its top. An inlet and an outlet communicating with the cooling space are opened at both ends of the length direction of the cooling box, and the top of the conveyor belt passes through the cooling space through the inlet and the outlet.

[0012] The air cooler is positioned above the conveyor belt, and multiple air coolers are distributed on both sides of the width of the cooling space. The air cooler is used to blow cold air onto the ceramic particles on the conveyor belt.

[0013] The auxiliary component includes two movable plates and a drive structure; the movable plates are movably disposed below the conveyor belt, and the drive structure is used to drive the two movable plates to move; the cooling space has spaces on both sides for cold air to flow through, and the space between the two movable plates is aligned with the heat dissipation vent in the vertical direction;

[0014] Both sides of the conveyor belt have protective sections to prevent the ceramsite from rolling off.

[0015] The drive structure includes a second drive element and a drive gear;

[0016] The drive gear is rotatably disposed at the bottom of the cooling box and below the conveyor belt, and its rotation axis coincides with its own axis and is parallel to the length direction of the cooling box; the second drive member is disposed on one side of the length direction of the cooling box, and is used to drive the drive gear to rotate, and the end of the movable plate near the drive gear has a rack structure that meshes with the drive gear.

[0017] By adopting the above technical solution, the stability of ceramsite during transportation can be effectively improved, reducing the probability of ceramsite moving and rolling off the conveyor belt during transportation and cooling. Furthermore, by having only the top of the conveyor belt pass through the cooling space, the size of the inlet and outlet can be effectively reduced, thus minimizing the loss of cold air flowing through the cooling space. Simultaneously, the cooling fans on both sides can blow cold air onto the ceramsite from different directions, and the drive structure can easily adjust the position of the two movable plates according to the usage of the cooling fans. This allows the movable plates to guide the cold air flowing along different routes, facilitating the circulation of cold air within the cooling space, and ultimately discharging it through the heat dissipation vents. This fully utilizes the cold air while improving the efficiency, effectiveness, and uniformity of ceramsite cooling, thereby effectively improving the quality of the cooled ceramsite. It also effectively increases the utilization rate of cold air, reduces cold air loss, reduces energy consumption for ceramsite cooling, and is more environmentally friendly.

[0018] Optionally, the bottom of the cooling box has multiple discharge ports on both sides in the width direction, and the bottom of the cooling box is movably provided with multiple cover plates for controlling the opening and closing of the discharge ports.

[0019] By adopting the above technical solution, the ceramsite entering the cooling space will be blown by the cold air, and the impurity particles transported with it will fall to the bottom of the cooling space. The impurities will be discharged through the discharge port to facilitate the staff to clean the impurities in the cooling space.

[0020] Optionally, the cover plate is linked with the adjacent movable plate;

[0021] When the movable plate moves upward to its limit position, the cover plate seals the corresponding discharge port; when the movable plate moves downward to its limit position, the cover plate opens the corresponding discharge port.

[0022] By adopting the above technical solution, when the movable plate moves to block and guide the upward flow of cold air, it can drive the adjacent cover plate to move and open the corresponding discharge port. At this time, the impurities around the discharge port can be discharged smoothly under their own gravity, while effectively reducing the probability of cold air loss and cold air affecting the discharge of impurities.

[0023] Optionally, it may also include a recycling device for collecting impurities;

[0024] The recycling device is located at the bottom of the machine body and includes a recycling box and two guide plates. The recycling box is located below the conveyor belt and has multiple upward-facing collection slots inside. The two guide plates are located on both sides of the conveyor belt and above the recycling box. An accumulation space for impurities is formed between the guide plates and the adjacent baffles. When the impurity discharge port is opened, impurities fall into the adjacent accumulation space, and the impurities in the accumulation space move with the bottom of the conveyor belt. The guide plates have multiple filter holes of different sizes that communicate with the accumulation space. The size of the multiple filter holes gradually increases along the moving direction of the bottom of the conveyor belt, and the filter holes of different sizes are located above different collection slots.

[0025] By adopting the above technical solution, impurities will fall into the adjacent collection space after being discharged from the discharge port. The impurities that accumulate in the collection space will move with the conveyor belt. During the movement, different impurities can pass through the corresponding filter holes and fall into the corresponding collection tank, so that they can be classified and recycled according to the type and size of the impurities.

[0026] Optionally, the cooling device further includes a cleaning component for removing impurities, and the cleaning component is located between the two movable plates;

[0027] The impurity removal assembly includes a rotating component and several impurity removal components; one end of the rotating component is fixedly connected to the drive gear, and the axis of the rotating component coincides with the rotation axis of the drive gear; one end of the impurity removal component is connected to the rotating component, and its other end contacts the inner wall of the bottom of the cooling space.

[0028] By adopting the above technical solution, the driving structure can also provide power to the impurity removal component during the process of driving the two movable plate covers to change their position. This allows the impurity removal component to move the impurities located at the bottom between the two movable plates toward the movable plate that moves upward to its limit position, so that the impurities can gather toward the position near the discharge port for easy subsequent discharge.

[0029] Optionally, the impurity removal assembly includes one impurity removal component, and the impurity removal component is composed of multiple flexible and elastic bristles arranged closely together;

[0030] When the movable plate moves upward to its limit position, the debris removal component rotates with the rotating component and tilts downward toward the direction close to the movable plate.

[0031] By adopting the above technical solution, when one movable plate moves upward to its limit position, the debris removal component between the two movable plates can guide the cold air to change its flow direction, so that the cold air entering the space between the two movable plates can flow upward and out through the heat dissipation vent, effectively reducing the loss of cold air in this process.

[0032] Optionally, when the movable plate moves upward to its limit position, the top of the movable plate drives the conveyor belt to deform upward; when the movable plate moves downward to its limit position, the bottom of the movable plate abuts against the inner wall of the bottom of the cooling space.

[0033] By adopting the above technical solution, during the process of the air cooler blowing cold air, the auxiliary components can drive the conveyor belt to deform, causing the ceramsite on the conveyor belt to roll towards the running air cooler, thereby improving the cooling effect of the ceramsite by the cold air and further improving the uniformity of the cooling of the ceramsite.

[0034] On the other hand, this application provides a circulating cooling method for processing ceramsite, which adopts the following technical solution:

[0035] A circulating cooling method for processing ceramsite, based on the aforementioned circulating cooling system for processing ceramsite, includes the following steps:

[0036] S1. Load the ceramsite onto the conveyor belt;

[0037] S2. To ensure that the ceramic particles are evenly distributed on the conveyor belt and to prevent stacking;

[0038] S3. The conveying device delivers the ceramsite into the cooling space. The cooling fans on both sides operate intermittently. The auxiliary component controls the two movable plates to adapt and change their positions accordingly, so that the cold air blown by the cooling fans flows sequentially over the top of the conveyor belt, one side of the conveyor belt, between the two movable plates, and out of the heat dissipation vent.

[0039] In summary, this application includes at least one of the following beneficial effects:

[0040] 1. It can effectively improve the cooling efficiency, effect, and uniformity of ceramsite, thereby effectively improving the quality of ceramsite after cooling;

[0041] 2. It can effectively reduce the loss of cold air during the circulation process, while also effectively reducing the loss of cold air, improving the utilization rate of cold air, reducing the energy consumption of ceramsite cooling, and making it more green and environmentally friendly.

[0042] 3. It can facilitate the discharge and classification of impurities, reduce the impurity content of the cooled ceramsite, and thus further improve the quality of the cooled ceramsite. Attached Figure Description

[0050] The following is in conjunction with the appendix Figures 1-6 This application will be described in further detail.

[0051] Example 1: Refer to Figure 1 and Figure 2 This application discloses a circulating cooling system for processing ceramsite, which is used to uniformly cool the calcined ceramsite to improve its quality after cooling. At the same time, it can remove impurities during the cooling process to reduce the impurity content of the ceramsite after cooling, thereby further improving the quality of the ceramsite.

[0052] The cooling system includes a body 1 that serves as a mounting carrier for other devices, a transport device 2 for transporting the calcined ceramsite, a cooling device 3 for cooling the calcined ceramsite, and a recovery device 4 for recovering impurities (such as slag produced during the calcination of ceramsite and foreign matter entering from the outside) inside the cooling device 3.

[0053] The main body 1 has a rectangular parallelepiped structure; the transport device 2 is installed along the length of the main body 1, and the top of the transport device 2 is used to transport the ceramsite along the length of the main body 1; the cooling device 3 is installed on the top of the main body 1 to facilitate the cooling of the ceramsite transported by the transport device 2; the recovery device 4 is installed at the bottom of the main body 1 to facilitate the collection of impurities that fall off during the cooling process of the ceramsite.

[0054] The transport device 2 includes a transport belt 21 for supporting and moving the ceramsite, a plurality of transport rollers 23 for driving the transport belt 21, and a first drive member 22 for providing power to the transport rollers 23 to drive the transport belt 21. In this embodiment, the transport belt 21 preferably has a perforated structure through which impurities can fall and pass; and preferably, the transport device 2 includes two transport rollers 23.

[0055] The conveyor roller 23 has a cylindrical structure. The two conveyor rollers 23 are rotatably installed at both ends of the length direction of the machine body 1. The rotation axis of the conveyor roller 23 coincides with its own axis and is parallel to the width direction of the machine body 1.

[0056] The conveyor belt 21 is simultaneously wound around two conveyor rollers 23, and the portion of the top of the conveyor belt 21 located between the two conveyor rollers 23 has a certain degree of slack, allowing for subsequent adjustment of the tilt of the conveyor belt 21 to drive the ceramsite on the conveyor belt 21 to roll and improve the uniformity of its cooling. Both sides of the conveyor belt 21 in the width direction have guard portions 211 to prevent the ceramsite from rolling away, and the guard portions 211 extend outward at an angle away from the main body of the conveyor belt 21. In this embodiment, it is preferable that the outer side of the conveyor rollers 23 has teeth, and both sides of the conveyor belt 21 in the width direction have chain structures that mesh with the teeth, so that the conveyor rollers 23 can maintain a stable driving effect during the tilt adjustment of the top of the conveyor belt 21.

[0057] The first driving component 22 is fixedly installed on one side of the machine body 1, and is used to drive the two transport rollers 23 to rotate synchronously and in the same direction. In this embodiment, the first driving component 22 is preferably a servo motor, which drives the two transport rollers 23 to rotate synchronously and in the same direction through a synchronous sprocket structure. Since the servo motor and the synchronous sprocket structure are common existing technologies, they will not be described in detail here, and they are only briefly shown in the accompanying drawings.

[0058] Reference Figure 3 and Figure 4 The cooling device 3 includes a cooling box 31 that provides space for cooling the ceramsite, multiple air coolers 32 for blowing cold air onto the ceramsite to cool it down, auxiliary components 33 for improving the cooling effect and uniformity of the ceramsite, and a cleaning component 34 for removing impurities from the inside of the cooling box 31.

[0059] The cooling box 31 has a rectangular parallelepiped structure and is fixedly installed on the top of the body 1. Its length and width are parallel to the length and width of the body 1, respectively. The interior of the cooling box 31 has a rectangular cooling space 311. At both ends of the cooling box 31 along its length are an inlet 312 and an outlet 313 for the top of the conveyor belt 21 to enter and exit the cooling space 311. The top of the cooling box 31 has a heat dissipation vent 314, and the bottom of the cooling box 31 has multiple discharge vents 315 for removing impurities from the cooling space 311. In this embodiment, preferably, the bottom of the cooling box 31 has two discharge vents 315, located near the two sides of the cooling box 31 along its width. Preferably, the heat dissipation vents 314 have a mesh structure to prevent external impurities from entering, and the projection of the heat dissipation vents 314 onto the bottom of the cooling box 31 is located between the two discharge vents 315.

[0060] Multiple air coolers 32 are fixedly installed on the top of the cooling box 31, located in the cooling space 311 above the top of the conveyor belt 21, and respectively located on both sides of the width direction of the top of the conveyor belt 21. In this embodiment, the cooling device 3 preferably includes two air coolers 32, which are symmetrically distributed in the cooling space 311, and the two ends of the air coolers 32 in the length direction respectively abut against the inner walls of the two ends in the length direction of the cooling space 311; and preferably, the air coolers 32 blow cold air along the width direction of the cooling box 31 towards the direction closer to the other air cooler 32, and the blowing range of the cold air covers the part of the top of the conveyor belt 21 located in the cooling space 311.

[0061] Furthermore, in order to prevent the cold air in the cooling space 311 from being directly discharged from the waste outlet 315, which would reduce the utilization rate of the cold air, and also to facilitate the timely discharge of impurities at the bottom of the cooling space 311 through the waste outlet 315, it is preferable that two cover plates 316 for controlling the opening and closing of the waste outlet 315 are also movably installed at the bottom of the cooling box 31.

[0062] The cover plate 316 has a rectangular plate-like structure. One side of its width is rotatably connected to the bottom of the cooling box 31. Its rotation axis is parallel to its own length and the length of the cooling box 31. An elastic element 317 is fixedly installed at the rotatable connection position between the cover plate 316 and the cooling box 31. The two ends of the elastic element 317 are fixedly connected to the cover plate 316 and the cooling box 31, respectively, and it has the tendency to drive the cover plate 316 to rotate to its limit position towards the corresponding discharge port 315. In this embodiment, the rotatable connection position between the cover plate 316 and the cooling box 31 is preferably located on the side of the discharge port 315 closer to the other discharge port 315; and the elastic element 317 is preferably a torsion spring. Since torsion springs are common prior art, they will not be described in detail here. The accompanying drawings only show its installation position and its structure is omitted.

[0063] When the cover plate 316 rotates to its limit position towards the corresponding discharge port 315, it seals the discharge port 315. At this time, impurities in the cooling space 311 above the discharge port 315 accumulate under the circulation of cold air, facilitating subsequent rotation of the cover plate 316 to open the discharge port 315 and discharge them. In this embodiment, it is preferable that when the cover plate 316 rotates to its limit position away from the corresponding discharge port 315, the width direction of the cover plate 316 is inclined downwards towards the direction away from the other cover plate 316.

[0064] The auxiliary component 33 includes two movable plates 331 and a drive mechanism for moving the movable plates 331 to change their position.

[0065] The movable plate 331 has a rectangular plate-like structure and is movably installed at the bottom of the cooling box 31 and located in the cooling space 311 below the top of the conveyor belt 21. The length of the movable plate 331 is parallel to the length of the cooling box 31, and its width is parallel to the height of the cooling box 31. Both ends of its length are in contact with the inner walls of both sides of the cooling space 311 along its length. The direction of movement of the movable plate 331 relative to the cooling box 31 is parallel to its own width. The two movable plates 331 are aligned with the two ends of the top width of the conveyor belt 21 along the automatic movement direction. There is space for cold air to flow between the two ends of the width of the conveyor belt 21 and the movable plate 331 and one side of the inner wall of the adjacent cooling space 311.

[0066] The movable plate 331 has limitations in its movement relative to the cooling box 31. When the movable plate 331 moves to its limit position towards the top of the conveyor belt 21, the top of the movable plate 331 will contact one end of the top of the conveyor belt 21 in the width direction, causing the top of the conveyor belt 21 to rise at this point. At the same time, the bottom of the movable plate 331 forms an aperture between itself and the inner wall of the bottom of the cooling space 311, allowing cold air to flow through. This causes the part of the top of the conveyor belt 21 located in the cooling space 311 to tilt downwards towards the other movable plate 331, making it easier for the ceramic particles on the conveyor belt 21 to roll under their own gravity, so that the surface of the ceramic particles can fully contact the cold air, thereby improving the uniformity of cooling of the ceramic particles. When the movable plate 331 moves to its limit position away from the top of the conveyor belt 21, a gap will be formed between the top of the movable plate 331 and the top of the conveyor belt 21, and its bottom will contact and abut against the inner wall of the bottom of the cooling space 311, which serves to guide the cold air in the cooling space 311. In this embodiment, the top of the movable plate 331 preferably has an arc-shaped structure, which facilitates its contact with the top of the conveyor belt 21 and raises it.

[0067] The drive mechanism is installed on one side of the cooling box 31 along its length. It is used to drive two movable plates 331 to move in opposite directions and synchronously relative to the cooling box 31. When one movable plate 331 moves to its limit position in the direction close to the top of the conveyor belt 21, the other movable plate 331 moves to its limit position in the direction away from the top of the conveyor belt 21.

[0068] The drive mechanism includes a second drive component 3321 and a drive gear 3322.

[0069] The drive gear 3322 is rotatably mounted at one end of the cooling box 31 along its length. Its rotation axis coincides with its own axis and is parallel to the length of the cooling box 31. It is located between two movable plates 331. The movable plate 331 has a rack structure distributed along its width at the end near the drive gear 3322. The drive gear 3322 meshes with the rack structures of both movable plates 331.

[0070] The second driving component 3321 is fixedly installed on one side of the cooling box 31 along its length, and is used to drive the driving gear 3322 to rotate relative to the cooling box 31. In this embodiment, the second driving component 3321 is preferably a servo motor.

[0071] Furthermore, to facilitate timely rotation of the cover plate 316 to open the discharge port 315 and discharge impurities from the cooling space 311, while reducing the probability of the discharge port 315 affecting the cold air circulation in the cooling space 311 when it is open, the bottom of the movable plate 331 preferably has several trigger rods 3311 extending outward along its width direction and engaging with the bottom of the cooling box 31. In this embodiment, the bottom of the movable plate 331 preferably has two trigger rods 3311, and the two trigger rods 3311 are respectively located near both ends of the movable plate 331 in the length direction.

[0072] During the movement of the movable plate 331 relative to the cooling box 31, the trigger rod 3311 remains in contact with the bottom of the cooling box 31 to maintain a certain degree of sealing, and the end of the trigger rod 3311 away from the movable plate 331 remains in contact with the surface of the adjacent cover plate 316 near the corresponding discharge port 315; when the movable plate 331 moves to its limit position towards the top of the conveyor belt 21, the end of the trigger rod 3311 away from the movable plate 331 is located inside the bottom of the cooling box 31, and the cover plate 316 remains in the state of sealing the corresponding discharge port 315; when the movable plate 331 moves to its limit position away from the top of the conveyor belt 21, the end of the trigger rod 3311 away from the movable plate 331 is located below the cooling box 31, and the cover plate 316 rotates to its limit position away from the corresponding discharge port 315.

[0073] The impurity removal component 34 is installed in the cooling box 31, located in the cooling space 311 between the two movable plates 331, and is powered by a drive mechanism.

[0074] The impurity removal component 34 includes a rotating component 341 and an impurity removal component 342 composed of multiple flexible and elastic bristles.

[0075] The rotating component 341 has a cylindrical structure, with one end of its length direction fixedly connected to the drive gear 3322, and its axis coincides with the rotation axis of the drive gear 3322; during the process of the second drive component 3321 driving the drive gear 3322 to rotate, the rotating component 341 will rotate relative to the cooling box 31.

[0076] The debris removal component 342 has a rectangular sheet structure, one end of which is fixedly connected to the rotating component 341 and extends outward along the radial direction of the rotating component 341. During the process of the second driving component 3321 driving the movable plate 331 to move, the debris removal component 342 rotates with the rotating component 341 with a restriction, and the end of the debris removal component 342 away from the rotating component 341 is kept in contact with the inner wall of the bottom of the cooling space 311.

[0077] When one movable plate 331 moves to its limit position towards the top of the conveyor belt 21 and the other movable plate 331 moves to its limit position away from the top of the conveyor belt 21, the debris removal component 342 will tilt relative to the width direction of the cooling box 31. The end of the debris removal component 342 away from the rotating component 341 is the inclined lower end and close to the movable plate 331 that moves to its limit position towards the top of the conveyor belt 21. At this time, the side of the debris removal component 342 close to the movable plate 331 that moves to its limit position towards the top of the conveyor belt 21 is used to guide the cold air entering between the two movable plates 331 upward towards the direction close to the heat dissipation vent 314, so that the cold air can cool the ceramic particles again after passing through the conveyor belt 21 and then be discharged together with the heat through the heat dissipation vent 314.

[0078] Reference Figure 5 and Figure 6 The recycling device 4 includes a recycling box 41 for collecting impurities and two guide plates 42 for guiding the impurities to fall.

[0079] The recycling box 41 has a rectangular parallelepiped structure and is movably mounted on the bottom of the machine body 1 and below the conveyor belt 21. Its length and width are parallel to the length and width of the machine body 1, and its direction of movement is parallel to its own length. The recycling box 41 has multiple upward-facing collection slots 411, distributed along its length, and used to collect impurities of different types or sizes. In this embodiment, the recycling box 41 is preferably slidably connected to the machine body 1 via rollers, and can be removed along its sliding direction for easy processing of the collected impurities. Preferably, the multiple collection slots 411 are of different sizes, with the largest slot for collecting the largest impurities, its upward projection completely covering the entire cooling box 31. The size of the impurities collected by the multiple collection slots 411 gradually decreases along the moving direction of the bottom of the conveyor belt 21.

[0080] Guide plates 42 are vertically mounted on the machine body 1. Two guide plates 42 are positioned near the two ends of the machine body 1 in the width direction, and are located on opposite sides of the conveyor belt 21 in the width direction. The facing surfaces of the two guide plates 42 are guide surfaces 421. The top of the guide surfaces 421 is close to the adjacent discharge port 315. After the cover plate 316 rotates to open the discharge port 315, impurities discharged from the discharge port 315 will slide down the cover plate 316 towards the adjacent guide surface 421, and then fall down along the guide surface 421. The bottom of the guide surface 421 is adjacent to one side of the bottom of the conveyor belt 21. The baffle 211 contacts and abuts against each other, and a gathering space 5 for impurities to accumulate is formed between the guide surface 421 and the baffle 211. Impurities falling into the gathering space 5 can move with the bottom of the conveyor belt 21. A plurality of filter holes 422 communicating with the gathering space 5 are opened through the guide plate 42. The plurality of filter holes 422 are distributed along the length direction of the body 1 on the guide plate 42. The plurality of filter holes 422 have different sizes, and the size of the filter holes 422 is adapted to the size of the collection target of the adjacent collection tank 411. The plurality of filter holes 422 are located above the corresponding collection tank 411. In this embodiment, it is preferable that the filter holes 422 communicate with the bottom of the gathering space 5, and it is preferable that the filter holes 422 are opened at an angle on the guide plate 42. At this time, the impurities moving in the gathering space 5 with the bottom of the conveyor belt 21 can fall into the corresponding collection tank 411 for collection under their own gravity after passing through the adapted filter holes 422.

[0081] Example 2: Refer to Figure 6 This application discloses a circulating cooling method for ceramsite processing, based on a circulating cooling system for ceramsite processing disclosed in Embodiment 1, comprising the following steps:

[0082] S1. Load the ceramsite onto the conveyor belt 21.

[0083] The calcined ceramsite is fed to the top of the conveyor belt 21, so that the ceramsite moves towards the cooling device 3 under the transport of the conveyor belt 21.

[0084] S2. To ensure that the ceramsite is evenly distributed on the conveyor belt 21 and to prevent stacking.

[0085] Before the expanded clay aggregate enters the cooling device 3 under the transport of the conveyor belt 21, the distribution of the expanded clay aggregate on the conveyor belt 21 is adjusted so that the expanded clay aggregate enters the cooling device 3 in a single layer and uniformly distributed state, so as to ensure the subsequent cooling efficiency, effect and uniformity of the expanded clay aggregate.

[0086] S3. The conveying device 2 delivers the ceramic particles into the cooling space 311. The cooling fans 32 on both sides operate intermittently. The adjusting component controls the two movable plates 331 to adapt and change their positions accordingly, so that the cold air blown by the cooling fans 32 flows sequentially over the conveyor belt 21, one side of the conveyor belt 21, between the two movable plates 331, and out of the heat dissipation vent 314.

[0087] The expanded clay aggregates are transported by the conveyor belt 21 and pass through the inlet 312 and outlet 313 and then through the cooling space 311. During this process, the air coolers 32 located on both sides are turned on and off at certain time intervals, so that the expanded clay aggregates on the conveyor belt 21 are cooled by contacting the air cooler on one side only each time.

[0088] The opening and closing of the air cooler 32 is linked to the operation of the auxiliary component 33. When the air cooler 32 on one side is started, the second drive component 3321 will drive the movable plate 331 on the same side to move downward to the limit position. At this time, the movable plate 331 on the other side will move upward to the limit position, so that the ceramsite on the conveyor belt 21 has a tendency to roll towards the direction of the started air cooler 32. During this process, the contact effect between the ceramsite and the cold air is better, so that the ceramsite is cooled better.

[0089] During the process of the air cooler 32 blowing cold air, the cold air will first flow from the top of the conveyor belt 21, and after contacting the inner wall on the other side of the cooling space 311, it will flow downward. Then, after contacting the inner wall at the bottom of the cooling space 311, it will flow towards the movable plate 331 that moves downward to its limit position and enter between the two movable plates 331. Then, under the guidance of the cleaning part 342 and the movable plate 331 that moves downward to its limit position, it will flow upward through the top of the conveyor belt 21, and after acting on the ceramic particles again to achieve a cooling effect, it will carry the heat out through the heat dissipation vent 314.

[0090] During this process, impurities that enter the cooling space 311 along with the ceramsite will fall through the perforations on the conveyor belt 21 to the middle of the bottom of the cooling space 311 or move with the flow of cold air to the top of the cover plate 316 that seals the discharge port 315. Meanwhile, the impurities that were originally located above the cover plate 316 that was open at the discharge port 315 will fall through the discharge port 315 and fall into the collection space 5 under the guidance of the guide surface 421. They will then move with the bottom of the conveyor belt 21 and leave the collection space 5 through the corresponding filter holes 422 before falling into the corresponding collection tank 411 for collection.

[0091] When the auxiliary component 33 adapts to the opening and closing state of the two side air coolers 32, causing the position of the two movable plates 331 to change, the impurity removal component 34 can drive the impurities located in the middle of the bottom of the cooling space 311 to move towards the impurity discharge port 315 which is covered by the cover plate 316, so that the impurities located in the middle of the bottom of the cooling space 311 can be discharged through the impurity discharge port 315.

[0092] S4. After the ceramsite cools, it is discharged and sent to the equipment corresponding to the next process.

[0093] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
