Description

Technical Field

[0001] This invention relates to the field of grate cooler equipment for cement cooling equipment, and specifically to a novel grate cooler that improves the blind spot of the grate bed. Background Technology

[0002] Due to the installation requirements of the grate bed, the company has a 200mm edge area for sealing strips and grate cooler housing installation, without grate gaps for ventilation and cooling. This results in the clinker on both sides of the clinker grate bed not being cooled, causing heat loss, high-temperature wear of clinker conveying equipment, and loss of clinker crystal transformation strength due to slow cooling.

[0003] The clinker on the sealing strip is not cooled by the cold air, causing a red-hot phenomenon. The high temperature of the clinker on the sealing strip leads to an increase in the temperature inside the grate cooler. As a result, the clinker exiting the grate cooler is at a relatively high temperature, which affects the quality of the cement. At the same time, since the sealing strip is installed on the shell of the grate cooler, the clinker on the sealing strip cannot move. The clinker on the sealing strip cannot be cooled by the cold air under the grate. Adjusting the cold air under the grate cannot regulate the temperature inside the grate cooler, which makes it impossible to control the temperature inside the grate cooler to the rated temperature. Summary of the Invention

[0004] To address the shortcomings of the existing technology, this invention proposes a novel grate cooler that improves the blind zone of the grate bed, facilitating the conveying of clinker on the sealing strip and simultaneously cooling the clinker on the sealing plate, thus ensuring the internal temperature of the grate cooler.

[0005] To achieve the above objectives, the present invention provides a novel grate cooler for improving the blind zone of a grate bed, comprising a housing, a grate plate, and a conveying mechanism. Sealing strips are installed on the inner walls of both sides of the housing, and a grate plate is installed inside the sealing strips. The grate plate and the sealing strips are slidably fitted. A conveying mechanism that moves with the grate plate is installed above each sealing strip. A blowing assembly is installed on the conveying mechanism to cool the clinker on the sealing plate. The conveying mechanism includes a translational shovel, a moving frame, and a sliding frame. Multiple sets of translational shovels are installed above the sealing strip and arranged side by side. The two sides of the multiple translational shovels are installed on the moving frame, and the translational shovels are raised and lowered on the moving frame. A sliding frame is installed on the inner wall of the outer shell. One side of the moving frame is slidably engaged with the sliding frame, and the other side of the moving frame is detachably connected to the grate. Multiple air holes smaller than the clinker are opened on the outer wall of the sliding shovel plate. A blower assembly is installed on the outer wall of the outer shell. The blower assembly passes through the outer shell to supply air to the air holes. A cold air supply assembly is installed on the outer shell and is connected to the blower assembly. The air duct is connected to the corresponding cold air supply assembly. Multiple air outlets are installed on the inner wall of the outer shell. The air outlets are connected to the blower assembly. An adjustment assembly is installed on the air outlet. The air volume of the air outlet is adjusted by adjusting the air outlet.

[0008] Preferably, the lifting assembly includes lifting guide grooves, with multiple opposing lifting guide grooves opened on the inner side of the movable frame. The two sides of the translating shovel are engaged in the lifting guide grooves of the movable frame, and the translating shovel moves up and down along the lifting guide grooves. The linkage assembly consists of telescopic rods and translating rods. Two lifting rods are installed below the translating rods, and two telescopic rods pass through the outer shell. The telescopic rods slide along the outer shell, and a telescopic assembly is provided between the telescopic rods and the outer wall of the outer shell. A sleeve is fitted on the translating rod, and the translating rod moves along the sleeve. A connecting rod is hinged between the sleeve and the telescopic rod. The two lifting rods are located at both ends of the multiple translating shovels, and a linkage rod is provided between the two lifting rods. The linkage rod is fixed to the top of the multiple translating shovels.

[0009] Preferably, a cold air supply assembly is passed through the outer casing and connected to the back of the translating shovel. The cold air supply assembly includes an air supply pipe and a telescopic pipe. The air supply pipe passes through the outer casing and is connected to the air blowing assembly. One end of the air supply pipe is a 90° bend. The telescopic pipe is inserted into the other end of the air supply pipe. A spring is provided between the telescopic pipe and the air supply pipe. The spring pushes the telescopic pipe forward. The other end of the telescopic pipe slides against the back of the translating shovel. A sealing plate is installed at the end of the telescopic pipe that connects with the translating shovel. The telescopic pipe is connected to the translating shovel.

[0010] Preferably, the front of the sliding shovel has a notch, and multiple equally spaced baffles are arranged in the notch. The gaps between the baffles form multiple air holes, which are connected to the telescopic pipe. The baffles are tilted upward, thus forming an upward wind direction.

[0011] Preferably, a second groove for the sealing plate to be inserted is installed on the back of the translating shovel plate, and a through hole is opened on the back of the translating shovel plate to connect with the notch and the telescopic tube, wherein the through hole is located at the top of the groove, and when the translating shovel plate descends, the telescopic tube communicates with the notch on the translating shovel plate.

[0012] Preferably, a discharge assembly is installed on the sealing strip, located at the end of the movable frame. The discharge assembly conveys the clinker on the sealing strip to the grate plate.

The discharge cylinder is inserted into the groove. A partition plate is installed on one side of the discharge cylinder groove facing the grate plate. The partition plate is higher than the height of the clinker on the grate plate. The end of the discharge cylinder above the partition plate is a cavity. A drive shaft driven by a motor is installed inside the discharge cylinder. A conveying plate is installed on the drive shaft. The edge of the conveying plate contacts the inner wall of the discharge cylinder. The conveying plate is a spiral plate. A feed groove is opened on the side wall of the discharge cylinder. The clinker on the sealing strip enters the discharge cylinder through the feed groove.

[0013] Preferably, an installation cylinder higher than the clinker on the grate is installed near the edges of both sides of the grate. A movable frame is provided at the top of the installation cylinder, and a support frame is fixed below the movable frame and pressed against the top surface of the installation cylinder.

[0026] The invention will now be further described with reference to the accompanying drawings.

[0027] like Figure 1-10 The present invention discloses a novel grate cooler for improving the blind spots of a grate bed, comprising a housing 1, a grate plate 3, and a conveying mechanism 4. Sealing strips 2 are welded onto the inner walls of both sides of the housing 1. A grate plate 3 is installed inside the sealing strips 2, and the grate plate 3 and sealing strips 2 slide together (sliding grooves are opened on both sides of the grate plate, and a track is fixed to the inner side of the sealing strip 2 by welding; the sliding grooves move along the track; this application adopts an existing grate bed structure and then improves upon it). A conveying mechanism 4 is installed above each sealing strip 2, moving along with the grate plate 3. A blowing assembly 10 is installed on the conveying mechanism 4 to cool the clinker on the sealing plate 14. The conveying mechanism 4 includes a translational shovel 5, a moving frame 7, and a sliding frame 8. Multiple sets of translational shovels 5 arranged side-by-side are installed above each sealing strip 2. The sides of the multiple translational shovels 5 are mounted on the moving frame 7 (the moving frame 7 is a rectangular frame with lifting guide grooves 18 on its inner side for raising and lowering the flat shovels 5). The translational shovels 5 rise and fall on the moving frame 7. The sliding frame 8 is welded to the inner wall of the outer casing 1, and the moving frame 7 and the sliding frame 8 slide in cooperation (e.g., ...). Figure 2 As shown, the sliding frame 8 is arranged longitudinally, and the movable frame 7 moves back and forth along the sliding frame 8. The other side of the movable frame 7 is detachably connected to the grate plate 3. When the movable frame 7 needs to move back and forth, the movable frame 7 is connected to the grate plate 3, and the reciprocating movement of the grate plate 3 drives the movable frame 7 to move back and forth (when the clinker on the sealing strip causes a red river phenomenon due to not cooling in time). When the movable frame does not need to move back and forth, the movable frame 7 is separated from the grate plate 3 (when there is less clinker on the sealing strip and no red river phenomenon occurs), and the movable frame stops moving.

[0028] Multiple air holes 6, smaller than clinker particles, are opened on the outer wall of the translational shovel plate 5. A blower assembly 10 (a high-pressure blower) is installed on the outer wall of the outer casing 1 by bolts. The blower assembly 10 supplies air to the air holes 6 through the outer casing 1. A cold air supply assembly 11 is installed on the outer casing 1 and is connected to the blower assembly 10. The air holes 6 are connected to the corresponding cold air supply assemblies 11. Multiple air outlets 16 are installed on the inner wall of the outer casing 1, and the air outlets 16 are fastened to the blower assembly 10 by bolts. The system is equipped with pipes that connect the air outlet 16 to the air blowing assembly 10. The cooling effect of the air blowing assembly 10 is delivered to the grate bed through the air outlet 16. At the same time, the air outlet 16 is directed towards the clinker on the sealing strip, thus cooling the clinker on the sealing strip. An adjustment component, which is a solenoid valve, is installed on the air outlet 16. The solenoid valve is also flanged and installed on the pipe. The air volume of the air outlet 16 is adjusted by the adjustment component (the air volume of the air outlet 16 is adjusted according to the cooling effect of the clinker on the sealing strip).

[0029] The movable frame 7 is a rectangular frame. The two ends of the translation shovel plate 5 are slidably engaged with the movable frame 7. The sliding frame 8 is the track. The sliding frame 8 is installed on the inner wall of the outer shell 1. A slider 9 that moves on the sliding frame 8 is installed on the sliding frame 8 (the slider 9 is long and narrow. The slider 9 is locked on the sliding frame 8. The slider is welded to the movable frame 7. In this way, the movable frame 7 can move back and forth on the sliding frame 8 through the slider 9). The other side of the movable frame 7 is detachably installed on the grate plate 3.

[0030] A lifting assembly 17 is provided between the translational shovel 5 and the moving frame 7. The lifting assembly 17 realizes the lifting and lowering of the translational shovel 5. A linkage assembly 20 that moves with the moving frame 7 is installed on the lifting assembly 17. When the moving frame 7 moves backward, the lifting assembly 17 rises through the linkage assembly 20. When the moving frame 7 moves forward, the lifting assembly 17 quickly descends through the linkage assembly 20. When the moving frame 7 moves forward, the translational shovel 5 descends, and the bottom of the translational shovel contacts the top of the sealing strip. When the moving frame moves forward, the translational shovel pushes the clinker forward. When the moving frame moves backward, the translational shovel rises to make way for the clinker. In this way, the translational shovel pushes the clinker on the sealing strip forward.

[0031] The lifting assembly 17 includes a lifting guide groove 18. The translating shovel 5 is engaged in the lifting guide groove 18 on both sides. The translating shovel 5 moves up and down along the lifting guide groove 18. The bottom of the lifting guide groove 18 is tilted forward, so the bottom of the translating shovel 5 is tilted downwards, forming a pointed bottom, which facilitates the translating shovel 5 descending and inserting into the clinker. The linkage assembly 20 consists of the telescopic rod 21 and the translating rod 22. Two vertical lifting rods 23 are welded below the translating rod 22. Two telescopic rods 21 pass through the outer casing 1, and the telescopic rods 21 slide left and right along the outer casing 1. Figure 2 As shown, a telescopic assembly 24 is provided between the telescopic rod 21 and the outer wall of the outer casing 1. The telescopic assembly 24 is a hydraulic cylinder, and the cylinder body of the telescopic assembly is fastened with bolts. The piston rod of the telescopic assembly 24 is fixed to the telescopic rod 21 by welding. Since the current grate plate reciprocates through a crank-rocker mechanism, the time for the grate plate to reciprocate is fixed. The telescopic assembly 24 is connected to the hydraulic pump through a solenoid valve. The solenoid valve is a three-position four-way valve, and the solenoid valve is connected to the input terminal of the PLC controller. The PLC controller controls the extension and retraction of the telescopic assembly 24 and adjusts the extension and retraction time of the telescopic assembly 24. When the grate plate moves backward, the telescopic assembly retracts; when the grate plate moves backward, the telescopic assembly retracts. When moving forward, the telescopic assembly rises, and a sleeve 25 is fitted onto the translation rod 22. The translation rod 22 moves along the sleeve 25. A connecting rod 26 is hinged between the sleeve 25 and the telescopic rod 21. Two lifting rods 23 are located at the front and rear ends of the multiple translation shovel plates 5. A linkage rod 27 (located at the bottom of the lifting rod 23) is fixed between the two lifting rods 23 by welding. The linkage rod 27 is fixed to the top of the multiple translation shovel plates 5 by welding. When the translation shovel plate needs to rise, the telescopic rod 21 moves outward, and the collar rises under the action of the connecting rod. In this way, the translation rod rises, and the translation shovel plate rises. When the translation shovel plate needs to fall, the telescopic rod moves inward to the inside of the outer shell, and the collar falls, and the translation shovel plate falls.

[0032] A cold air supply assembly 11, connected to and communicating with the back of the translating shovel plate 5, passes through the outer casing 1. The cold air supply assembly 11 includes an air supply pipe 12 and a telescopic pipe 13. The air supply pipe 12 passes through the outer casing 1 and communicates with the blower assembly 10 (high-pressure blower). The other end of the air supply pipe 12 is a 90° bend. The telescopic pipe 13 is inserted into the outer casing at the end of the air supply pipe 12. The telescopic pipe 13 slides back and forth along the air supply pipe 13. A spring is fitted between the telescopic pipe 13 and the air supply pipe 12, and the spring pushes the telescopic pipe 13 forward. The other end of the telescopic pipe 13 slides against the back of the translating shovel plate 5. A sealing plate 14 is installed at the end of the telescopic pipe 13 that connects with the translating shovel plate 5. 13 is connected to the translational shovel 5. A sandwich layer communicating with the air vent is opened on the translational shovel. A through hole communicating with the sandwich layer is opened on the back of the translational shovel. The sealing plate 14 covers the through hole. A sliding groove is fixed on the back of the translational shovel by welding. The two ends of the sealing plate are locked in the second sliding groove 15. In this way, the sealing plate slides along the back of the translational shovel. The telescopic tube 13 passes through the sealing plate. The end of the telescopic tube 13 is flush with the sealing plate. When the translational shovel descends, the telescopic tube communicates with the sandwich layer of the translational shovel through the through hole. When the translational shovel rises, the telescopic tube disconnects from the sandwich layer of the translational shovel. In this way, cold air is blown from the air vent of the translational shovel through the air supply pipe 12, the telescopic tube 13 and the waist-shaped groove.

[0033] The front of the sliding shovel plate 5 has a notch 28 (the front end of the sliding long plate is the front). Multiple equally spaced partitions 29 are fixed in the notch 28 by welding. The gaps between the partitions 29 form multiple air holes 6. The air holes 6 are connected to the telescopic pipe 13. The partitions 29 are tilted upward, thus forming an upward wind direction. The upward wind blows towards the clinker to ensure the cooling effect of the clinker.

[0034] A second groove 15 for the sealing plate 14 to be inserted is installed on the back of the translational shovel plate 5. A through hole is opened on the back of the translational shovel plate 5 to connect with the notch 28 and the telescopic tube 13. The through hole is located at the top of the groove. When the translational shovel plate 5 descends, the telescopic tube 13 is connected to the notch 28 on the translational shovel plate 5.

[0035] A discharge assembly 30 is installed on the sealing strip 2. The discharge assembly 30 is located on the sealing strip 2 at the end of the movable frame 7. The discharge assembly 30 conveys the clinker on the sealing strip 2 to the grate plate 3 for conveying. A baffle 32 is installed on the inner side of the end of the sealing strip 2 by welding to separate the grate plate 3 from the sealing strip 2. The baffle 32 is located at the end of the discharge assembly 30 and the sealing strip 2. The discharge assembly 30 is the discharge cylinder 31 and the conveying plate 34. A groove is opened on the sealing strip 2 to embed the discharge cylinder 31. The discharge cylinder 31 is inserted into the groove. A partition plate 33 is fixed to the side of the discharge cylinder 31 facing the grate plate 3 by welding. The partition plate 33 is higher than the height of the clinker on the grate plate 3. To prevent the clinker on the grate from entering the discharge cylinder 31, the end of the discharge cylinder 31 above the partition 29 is hollow. A drive shaft driven by a motor is installed inside the discharge cylinder 31. A conveyor plate 34 is welded onto the drive shaft. The edge of the conveyor plate 34 contacts the inner wall of the discharge cylinder 31. The conveyor plate 34 is a spiral plate. A feed groove 35 is opened on the side wall of the discharge cylinder 31 facing the moving frame. The swing shovel pushes the clinker into the discharge cylinder 31. The clinker on the sealing strip 2 enters the discharge cylinder 31 through the feed groove 35. The rotation of the conveyor plate 34 conveys the clinker in the discharge cylinder 31 inward. When the clinker is higher than the partition plate, the plastic is discharged from the discharge cylinder onto the grate.

[0036] An installation cylinder 36, higher than the clinker on the grate 3, is welded to the edges near both sides of the grate 3. A movable frame 7 is installed at the top of the installation cylinder 36. A support frame 37, pressed against the top surface of the installation cylinder 36, is fixed below the movable frame 7 by welding. A movable pin 38 passes through the support frame 37 and is inserted into the installation cylinder 37 to achieve linkage between the grate 3 and the movable frame 7. A top pin 39, which extends and retracts within the installation cylinder 37, is inserted inside the installation cylinder 37 (the top pin fits against the inner wall of the installation cylinder 37; when the bottom of the installation cylinder 37 is inflated, the top pin moves upward). At the bottom of the installation cylinder 37... A high-pressure air pipe 40 is connected to the mounting cylinder 37 (the bottom of the mounting cylinder 37 passes through the grate plate, and the bottom of the mounting cylinder 37 protrudes from the bottom of the grate plate; the high-pressure air pipe is connected to a high-pressure pump). Air is supplied to the mounting cylinder 37 through the high-pressure air pipe 40, so that the top pin 39 rises and is flush with the top of the mounting cylinder 37. The top pin 39 pushes the pin upward, thus separating the pin from the mounting cylinder 37. A connecting plate 41 is installed between the mounting cylinders 37 by welding. The top of the connecting plate 41 is flush with the top of the mounting cylinder 37 to prevent the bottom of the pin from being lower than the top of the mounting cylinder when the pin is misaligned with the mounting cylinder. When the pin and the mounting cylinder are aligned vertically, the pin is inserted into the mounting cylinder.
