Description

Technical Field

[0001] This invention relates to the field of heat exchanger technology, and in particular to a ceramic raw material powder heat exchanger. Background Technology

[0002] In the ceramics processing, it is necessary to process the important raw material alumina. The ground aluminum hydroxide powder needs to be calcined at high temperature. After calcination, the powder needs to be cooled rapidly to maintain its loose and porous structure, ensuring high specific surface area and chemical reactivity. If it is cooled slowly, it will become dense and hard, and the reactivity will be greatly reduced. Therefore, after the powder is calcined, an efficient heat exchanger is needed to exchange heat and cool it down.

[0003] Existing technologies typically employ cooling drums or powder heat exchangers for cooling. Drum coolers have low cooling efficiency, and the interlacing of heat transfer plates inside powder heat exchangers increases the bonding friction between the heat transfer plates and the powder layer due to the anchoring effect generated by the internal plates during gravity settling. The tension at the contact point is transmitted deep into the powder, making it difficult to guarantee the powder output rate. Furthermore, the powder is prone to clogging after absorbing moisture and agglomerating. Summary of the Invention

[0014] This invention provides a ceramic raw material powder heat exchanger, which has the following advantages:

[0015] 1. Through the corrugated cylinder, cold water can circulate and contact the upper part of the herringbone hollow plate for cooling. After being cooled by the circulating cold water, the corrugated cylinder can guide and transport the powder while exchanging heat and cooling it during rotation. This avoids the situation in traditional powder flow heat exchangers where the output rate of the powder after heat exchange is difficult to guarantee during the rapid cooling and transport of high-temperature powder.

[0016] 2. By engaging and linking bevel gears with other gears, the upper and lower ends of the flexible corrugated pipe can rotate synchronously. Cold water is then supplied from both sides through the upper circulation pipe, which can completely fill the inside of the corrugated pipe with cold water. This allows all the grooves of the herringbone hollow plates of the corrugated pipe to be immersed in cold water, ensuring that the contact temperature between the powder and the rotatable corrugated pipe remains at a low temperature, thereby improving the cooling efficiency of the powder.

[0017] 3. The powder is diverted into the cylindrical silo through the gaps between the vertically ribbed baffle A, the vertically ribbed square tube, and the vertically ribbed baffle B. The reciprocating shaking internal structure can prevent the powder from clogging during the diversion process. At the same time, the vertically ribbed structure increases the contact area between the powder and the plate during the flow guidance process. During the transmission process, the transparent vertically ribbed structure facilitates heat dissipation of the powder, avoiding the anchoring effect of the corrugated heat transfer plate inside the traditional heat exchanger that hinders the flow of the powder.

[0018] 4. Inject some cold water into the corrugated cylinder so that the liquid level is lower than the through hole of the cone cap but higher than the pipe opening at the bottom of the inclined branch pipe to prevent cold water from leaking out from the through holes on both sides of the cone cap. After starting the chiller unit, it cools the water flow inside the spiral wound tube heat exchanger. The cooled water flow inside the spiral wound tube heat exchanger then cools several sets of corrugated cylinders through the circulation pipe. The corrugated cylinders then exchange heat with and cool the powder. By vertically stacking the heat exchangers, a high-efficiency cooling tower is formed, realizing the cascade cooling of high-temperature powder. Attached Figure Description

[0034] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples.

[0035] Please see Figure 1-7 Embodiment 1 of the present invention: The present invention provides a ceramic raw material powder heat exchanger, including a main chamber, a buffer chamber 1 at the top of the main chamber, a rhomboid notch 2 on the left and right sides of the bottom of the buffer chamber 1, a rhomboid hole 3 in the middle of the main chamber in a horizontal direction, a flame-retardant cloth sleeve A4 fixedly connected to the inner edge of the rhomboid notch 2, a triangular hole 5 in the middle of the main chamber in a horizontal direction, the triangular hole 5 being below the rhomboid notch 2 and the rhomboid hole 3, a cylindrical chamber 6 fixedly connected inside the main chamber, the number of cylindrical chambers 6 being at least three sets, a ventilation hole 7 in the horizontal direction of the main chamber, the ventilation hole 7 being located on the left and right sides below the cylindrical chamber 6, and a fixed connection being made on the outer side of the cylindrical chamber 6 and the inner side of the ventilation hole 7. The inner support 9 is provided inside the triangular hole 5 and has heat dissipation fins 8. The bottom of the inner support 9 is slidably connected to a slide rail A901, which is fixedly connected to the bottom of the triangular hole 5. The inner side of the inner support 9 is fixedly connected to the vertical striped folded plate A201, the vertical striped square tube 302, and the vertical striped folded plate B502. A crank-connecting rod mechanism 10 is provided on the top surface of the middle part of the main chamber. The telescopic rod part of the crank-connecting rod mechanism 10 is fixedly connected to the crossbeam at the front end of the inner support 9. The crank side end of the crank-connecting rod mechanism 10 is coaxially connected to a pulley A1001. Conical caps 11 are rotatably connected to the left and right sides inside each set of cylindrical chambers 6. The side end of the conical cap 11 is provided with a through hole, and a sealed bearing is installed at the through hole. 1101, A pulley B1102 is fixedly connected to the left side of the cone cap 11. The pulley B1102 is coaxial with the cone cap 11 and is driven by a belt. The frontmost set of pulleys B1102 in the main chamber is driven by a belt to pulley A1001. A bellows cylinder 1103 is fixedly connected to the side end of the cone cap 11. A shuttle-shaped cylinder 1107 is fixedly connected to the inside of the bellows cylinder 1103 by a bracket. The liquid level inside the bellows cylinder 1103 is lower than the bottom of the through hole of the cone cap 11. The curved surface of the bellows cylinder 1103 is provided with herringbone hollow plates 1106. A dual-shaft motor 12 is fixedly installed on the left side of the outside of the cylindrical chamber 6. Tensioning wheels are rotatably connected to the left and right sides of the outside of the cylindrical chamber 6. 13. A spiral wound tube heat exchanger 14 is fixedly installed at the front end of the main chamber. A chiller unit 15 is connected to the outside of the spiral wound tube heat exchanger 14. First, some cold water is injected into the corrugated tube 1103 so that its liquid level is lower than the through hole of the cone cap 11 and higher than the pipe opening at the bottom of the inclined branch pipe 1205 to prevent cold water from leaking out from the through holes on both sides of the cone cap 11. After the chiller unit 15 is started, it cools the water flow inside the spiral wound tube heat exchanger 14. The low-temperature water flow inside the spiral wound tube heat exchanger 14 after cooling cools down through the circulation pipe 1204 to cool down several sets of corrugated tubes 1103. The corrugated tubes 1103 then exchange heat with the powder and cool it down, realizing the cascade refrigeration of high-temperature powder.

[0036] like Figure 1-4As shown, a vertically ribbed folded plate A201 is provided on the inner side of the rhomboid notch 2. The edge of the vertically ribbed folded plate A201 is fixedly connected to the flame-retardant cloth sleeve A4. A flame-retardant cloth sleeve B301 is fixedly connected to the inner edge of the rhomboid hole 3. A vertically ribbed square tube 302 is fixedly connected to the inner side of the flame-retardant cloth sleeve B301. A rectangular notch is opened at the top of the triangular hole 5. A flame-retardant cloth sleeve C501 is fixedly connected to the edge of the rectangular notch. A vertically ribbed folded plate B502 is fixedly connected to the top of the flame-retardant cloth sleeve C501. The vertically ribbed folded plate B502 is located at the center of the gap between the vertically ribbed folded plate A201 and the vertically ribbed square tube 302. The dual-shaft motor 12 is driven, and after the torque is increased by the reducer, the transmission gear A1203 drives the cone cap 11 to rotate. The pulley B1102 on the side of the cone cap 11 drives the belt pulley. When A1001 rotates, the pulley A1001 drives the crank to rotate. Through linkage, the telescopic part of the crank-connecting rod mechanism 10 drives the inner support 9 to move back and forth on the horizontal plane. The inner support 9 drives the inner vertical striped folding plate A201, vertical striped square tube 302 and vertical striped folding plate B502 to move back and forth laterally. After passing through the buffer chamber 1, the high-temperature powder is diverted into the cylindrical chamber 6 through the gap between the vertical striped folding plate A201, vertical striped square tube 302 and vertical striped folding plate B502. The reciprocating shaking internal structure can prevent powder blockage during the diversion process. At the same time, the vertical striped structure increases the contact area between the powder and the plate during the flow guidance process. During the transmission process, the transparent vertical striped structure facilitates heat dissipation of the powder and avoids the anchoring effect of the corrugated heat transfer plate inside the traditional heat exchanger, which hinders the flow of the powder.

[0037] like Figure 1-6As shown, the top of the cylindrical silo 6 is provided with an inlet 601, which is located below the gap between the vertical ribbed plate A201 and the vertical ribbed plate B502. The bottom of the cylindrical silo 6 is provided with an outlet 602. Angular contact bearings 603 are installed on the left and right sides of the cylindrical silo 6. The inner ring of the angular contact bearing 603 is fixedly connected to the outer curved surface of the cone cap 11. The outlet 602 is located slightly forward of the inlet 601. A circulation pump 1201 is fixedly connected to the front end of the dual-shaft motor 12. A worm gear reducer 1202 is fixedly connected to the rear end of the dual-shaft motor 12. A transmission gear A1203 is coaxially connected to the output shaft of the worm gear reducer 1202. An internal gear 1104 is fixedly connected to the inner curved surface of the pulley B1102, and the internal gear 1104 meshes with the transmission gear A1203. A circulation pipe 1204 is connected to the outside of the circulation pump 1201 through a flange. An inclined branch pipe 1205 is fixedly connected to the side end of the circulation pipe 1204. The angle of the inclined branch pipe 1205 is... Parallel to the side profile of the cone cap 11 and the bottom edge of the shuttle-shaped cylinder 1107, the transmission gear A1203 engages with the internal gear 1104, causing the dual-shaft motor 12 to drive the cone cap 11 to rotate counterclockwise. The high-temperature powder enters the cylindrical silo 6 through the inlet 601 after being diverted. The powder falls downward into the gap of the herringbone hollow plate 1106. During the rotation and transmission of the powder inside the cylindrical silo 6, the ventilation holes 7 and heat dissipation fins 8 on the outside of the cylindrical silo 6 dissipate heat and cool it down. At the same time, the circulating water flows through the circulation pipe 1204 and circulates inside the corrugated cylinder 1103. The lower half of the corrugated cylinder 1103 is immersed in cold water. During the rotation, the cold water can circulate and contact the upper half of the herringbone hollow plate 1106 to cool it down. After being cooled by the circulating cold water, the corrugated cylinder 1103 can transfer the powder and exchange heat and cool it down during the rotation. In the process of rapid cooling and transmission of high-temperature powder, it can avoid the long-term retention of high-temperature powder to absorb moisture and clump together.

[0038] Example 2: Based on Example 1, as follows Figure 8-10As shown, a toothed ring A1105 is fixedly connected to the side end of the cone cap 11. A flexible bellows 16 is connected to the side end of the cone cap 11 via a flange. The upper and lower ends of the flexible bellows 16 are rigid pipes. External supports 17 are provided on the left and right sides of the main chamber. The liquid level inside the flexible bellows 16 is always higher than that of the bellows 1103. The rigid pipe at the upper end of the flexible bellows 16 is rotatably connected to the inner side of the external support 17. A toothed ring B1601 is fixedly connected to the outer side of the rigid pipe at the upper end of the flexible bellows 16. The height of the top of the rigid pipe at the upper end of the flexible bellows 16 is higher than the height of the top of the bellows 1103. The bottom of the branch pipe of the circulation pipe 1204 is inserted through the upper end of the flexible bellows 16. Inside the rigid pipe, a vertical shaft 1701 is rotatably connected to the inner side of the outer support 17. A transmission gear B1702 is coaxially connected to the top of the vertical shaft 1701, meshing with a gear ring B1601. A bevel gear A1703 is coaxially connected to the bottom of the vertical shaft 1701, and a bevel gear B1704 is coaxially connected to the bottom of bevel gear A1703. A horizontal shaft A1705 is rotatably connected to the bottom of the outer support 17, and a transmission gear C1706 is coaxially connected to the side end of the horizontal shaft A1705, meshing with a gear ring A1105. A bevel gear C1707 is coaxially connected to the other side of the horizontal shaft A1705. 1707 meshes with bevel gear A1703. A drive mechanism 18 is fixedly mounted on the front end of the outer bracket 17. A horizontal shaft B1801 is rotatably connected to the bottom of the outer bracket 17. The horizontal shaft B1801 is coaxially connected to the output shaft of the reducer of the drive mechanism 18. A bevel gear D1802 is coaxially connected to the horizontal shaft B1801. The bevel gear D1802 meshes with bevel gear B1704. During the rotation of the horizontal shaft B1801 driven by the drive mechanism 18, the bevel gear D1802 on the horizontal shaft B1801 can drive the bevel gear B1704 to rotate. Simultaneously, the bevel gear A1703, coaxially located above the bevel gear B1704, drives the bevel gears meshing with it. When wheel C1707 rotates, bevel gear C1707 drives transmission gear C1706, which is coaxial with it on horizontal shaft A 1705, to rotate. Transmission gear C1706 drives gear ring A1105, which meshes with it, to rotate. At the same time, transmission gear B1702 at the top of vertical shaft 1701 drives gear ring B1601, which meshes with it, to rotate. This achieves synchronous rotation of the upper and lower ends of flexible bellows 16. Cold water is supplied from the left and right sides through the upper circulation pipe 1204, which can completely fill the inside of bellows 1103 with cold water. This allows all the grooves of the herringbone hollow plates 1106 of bellows 1103 to be immersed in cold water, which can improve the cooling efficiency of powder.

[0039] Example 3: Based on Example 1, after the left and right ends of the vertical striped square tube 302 are sealed with a plate, it is connected to the circulation pipe 1204 through a flexible pipe. At the same time, a flexible waterproof layer is added to the flame-retardant cloth cover B301. Cold water is transported through the circulation pipe 1204 so that cold water enters the interior of the vertical striped square tube 302, which can initially cool the high-temperature powder.

[0040] The specific usage and function of this embodiment: When using this invention, firstly, some cold water is injected into the corrugated cylinder 1103 so that its liquid level is lower than the through hole of the cone cap 11, but higher than the bottom opening of the inclined branch pipe 1205, to prevent cold water from leaking out from the through holes on both sides of the cone cap 11. After starting the chiller unit 15, it cools the water flow inside the spiral wound tube heat exchanger 14. The cooled water flow inside the spiral wound tube heat exchanger 14 then cools several sets of corrugated cylinders 1103 through the circulation pipe 1204. The corrugated cylinders 1103 then exchange heat and cool the powder. The dual-shaft motor 12 operates, and after the torque is increased by the reducer, the transmission gear A1203 drives the cone cap 11 to rotate. The pulley B1102 on the side of the cone cap 11 drives the cone cap 11 to rotate through the belt pulley. The belt pulley A1001 rotates, which in turn drives the crank to rotate. Through linkage, the telescopic part of the crank-connecting rod mechanism 10 drives the inner support 9 to reciprocate in the horizontal plane. The inner support 9 drives the inner vertical ribbed plate A201, vertical ribbed square tube 302, and vertical ribbed plate B502 to reciprocate laterally. After passing through the buffer bin 1, the high-temperature powder is diverted into the cylindrical bin 6 through the gaps between the vertical ribbed plate A201, vertical ribbed square tube 302, and vertical ribbed plate B502. The reciprocating shaking internal structure can prevent powder blockage during the diversion process. The transmission gear A1203 engages with the internal gear 1104, causing the dual-shaft motor 12 to drive the cone cap 11 to rotate counterclockwise. The high-temperature powder enters the cylindrical bin 6 through the inlet 601 after diversion, and the powder falls downwards into the manhole. During the rotation and transfer of powder within the cylindrical silo 6, the gaps in the herringbone hollow plates 1106 allow for heat dissipation and cooling of the powder through the ventilation holes 7 and heat dissipation fins 8 on the outside of the cylindrical silo 6. Simultaneously, circulating water flows through the circulation pipe 1204 and circulates within the corrugated cylinder 1103. Cold water is immersed in the lower half of the corrugated cylinder 1103. During rotation, the cold water circulates and cools the upper half of the herringbone hollow plates 1106. After being cooled by the circulating cold water, the corrugated cylinder 1103 can transfer powder while simultaneously exchanging heat and cooling it. In other embodiments, during the rotation of the horizontal shaft B1801 driven by the drive mechanism 18, the bevel gear D1802 on the horizontal shaft B1801 can drive the bevel gear B1704 to rotate, while simultaneously... The bevel gear A1703, coaxial above gear B1704, drives the bevel gear C1707, which meshes with it, to rotate. The bevel gear C1707 drives the transmission gear C1706, which is coaxial with it on the horizontal shaft A1705, to rotate. The transmission gear C1706 drives the gear ring A1105, which meshes with it, to rotate. At the same time, the transmission gear B1702, at the top of the vertical shaft 1701, drives the gear ring B1601, which meshes with it, to rotate. This achieves synchronous rotation of the upper and lower ends of the flexible bellows 16. Cold water is supplied from the left and right sides through the circulation pipe 1204 above, which can completely fill the inside of the bellows 1103 with cold water. This allows all the grooves of the herringbone hollow plates 1106 of the bellows 1103 to be immersed in cold water, which can improve the cooling efficiency of the powder.
