Description

Technical Field

[0001] This utility model relates to the field of cooling, specifically a flap-type cooler. Background Technology

[0002] In many fields such as industrial production, food processing, and chemical industry, it is often necessary to cool various materials to meet the requirements of subsequent production processes or product quality standards. The flap cooler is a type of equipment commonly used for cooling materials such as granular materials and expanded materials. It has the characteristics of good cooling effect and uniform material discharge. The flap cooler is widely used in many fields such as industrial production, food processing, and chemical industry.

[0003] In existing flap-type coolers, the cooling fan runs continuously during operation, and the cooling air moves upward against the material, gradually cooling it. The air is then discharged from the upper exhaust duct. To prevent material dust from overflowing from the exhaust duct, a dust filter is usually installed to filter the material dust. However, over time, a large amount of material dust accumulates on the dust filter. Existing technologies typically involve removing the dust filter for recycling or installing a cleaning structure to remove the dust. However, some material dust is lightweight, and because the cooling air from the fan moves upward, it is difficult for the dust to fall and be discharged from the outlet. As a result, this material dust remains inside the machine after the cooling process is complete. Therefore, we propose a flap-type cooler. Utility Model Content

[0004] The purpose of this utility model is to provide a flap-type cooler, including a housing, in which an exhaust pipe and a cooling pipe are installed through the inner side of the housing. The exhaust pipe is higher than the cooling pipe, and a middle pipe connects the exhaust pipe and the cooling pipe. The end of the cooling pipe located outside the housing is connected to the air outlet of a cooling fan. A dustproof net one is fixedly installed at the end of the exhaust pipe located inside the housing cavity, and a dustproof net two is fixedly installed at the end of the cooling pipe located inside the housing cavity. The flow of cooling air is adjusted by an air regulating component to meet different working needs during and after cooling operations.

[0005] Preferably, the housing is fixedly mounted on the frame, and the cooling fan is fixedly mounted on the frame.

[0006] Preferably, the frame is equipped with a discharge pipe replacement assembly, which can be used to meet different discharge requirements at the discharge port at the bottom of the box.

[0007] Preferably, a shut-off valve is installed on the top of the housing, which is used for feeding and shutting off the airflow.

[0008] Preferably, the air regulating component includes a hydraulic cylinder, which is fixedly installed on the top of the exhaust pipe. The telescopic end of the hydraulic cylinder is fixedly connected to a lifting plate. The bottom of the lifting plate is fixedly connected to two sets of short rods and two sets of long rods. The two sets of short rods slide through the inside of the exhaust pipe and are fixedly connected to an L-shaped blocking plate. The bottom of the two sets of long rods is fixedly connected to a blocking plate, which slides through the inside of the cooling pipe.

[0009] Preferably, the housing is rotatably connected to the rotating shaft via two sets of sealed bearings, and multiple sets of flaps are fixedly installed on the outer wall of the rotating shaft. All flaps are located inside the housing cavity. One end of the rotating shaft is fixedly connected to the drive end of the reducer via a coupling, and the reducer is fixedly installed on the support frame on the outer wall of the housing.

[0010] Preferably, the discharge pipe replacement assembly includes a connecting frame, with two sets of guide rods slidingly passing through the inner side of the connecting frame. The guide rods are fixedly installed between a first limiting plate and a second limiting plate. A second hydraulic cylinder is fixedly installed on the second limiting plate. The telescopic end of the second hydraulic cylinder is fixedly connected to the connecting frame. Both the first limiting plate and the second limiting plate are fixedly connected to the machine frame.

[0011] Preferably, the connecting frame is fixedly connected to discharge pipe one and discharge pipe two, and a sealing gasket is embedded in the discharge port at the bottom of the box.

[0012] Preferably, an air baffle roller is rotatably mounted inside the discharge pipe via a sealed bearing. One end of the air baffle roller is fixedly connected to the drive end of a servo motor via a coupling. The servo motor is fixedly mounted on a mounting bracket on the outer wall of the discharge pipe. A material groove is provided on the air baffle roller. The outer wall of the air baffle roller movably fits against the arc-shaped inner wall of the discharge pipe.

[0013] Compared with the prior art, the beneficial effects of this utility model are: This utility model, based on usage requirements, adjusts the flow of cooling air through an air regulating component to meet different work needs during and after cooling operations. During cooling, the cooling air moves from bottom to top to cool the material, resulting in good cooling effect. After cooling, the cooling air moves from top to bottom, continuously passing through the dustproof net, blowing down the material dust accumulated on the net, and blocking the cooling pipe. At this time, the cooling air inside the box can only move downwards and exit from the bottom outlet of the box. As the cooling air moves downwards, it also carries the material dust downwards and exits from the discharge pipe, facilitating the collection of material dust.

[0014] According to usage requirements, this utility model replaces the discharge pipe component to meet different discharge requirements at the bottom discharge port of the box. This allows either discharge pipe one or discharge pipe two to be connected to the bottom discharge port of the box. During cooling operation, discharge pipe one is connected to the bottom discharge port of the box. Due to the obstruction of the air baffle roller, the material cannot be discharged directly, and the cooling air inside the box cannot be discharged through the discharge port. Starting the servo motor will drive the air baffle roller to rotate. During the rotation of the air baffle roller, the material entering the trough can enter discharge pipe one and then be discharged from discharge pipe one. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Reference Figure 1 - Figure 7This utility model discloses a flap-type cooler, comprising a housing 1, with an exhaust pipe 2 and a cooling pipe 3 installed through the inner side of the housing 1. The exhaust pipe 2 is higher than the cooling pipe 3. A middle pipe 4 connects the exhaust pipe 2 and the cooling pipe 3. The end of the cooling pipe 3 located outside the housing 1 is connected to the air outlet of a cooling fan 5. A dustproof net 6 is fixedly installed at the end of the exhaust pipe 2 located inside the housing 1, and a second dustproof net 7 is fixedly installed at the end of the cooling pipe 3 located inside the housing 1. The flow of cooling air is adjusted by an air regulating component 8 to meet different working needs during and after the cooling operation. The housing 1 is fixedly installed on the frame 9, and the cooling fan 5 is fixedly installed on the frame 9; both the housing 1 and the cooling fan 5 are fixedly installed on the frame 9, making the installation structure of the housing 1 and the cooling fan 5 stable.

[0019] The frame 9 is equipped with a discharge pipe replacement assembly 10, which can meet the different discharge requirements of the discharge port at the bottom of the box 1. During use, the discharge pipe replacement assembly 10 can be used to move either discharge pipe one 15 or discharge pipe two 16 below the discharge port at the bottom of the box 1.

[0020] The top of the housing 1 is connected to a shut-off valve 11, which is used for feeding and shutting off the air. The shut-off valve 11 has a rotor with several blades that rotates inside the cylindrical housing. Material falls from the upper hopper and fills the spaces between the blades. As the blades rotate, the material is discharged to the lower part. The side of the housing is provided with a pressure equalization exhaust port, which can discharge the high-pressure gas brought by the impeller rotation, reduce the phenomenon of gas pushing against the material, and facilitate the smooth falling of the material. When feeding material into the housing 1, the shut-off valve 11 can directly block most of the gas from leaking through the gaps. It should be noted that when using the shut-off valve 11, it needs to be connected to a suitable external power supply with its dedicated controller and its operation is controlled by the controller.

[0021] The air conditioning assembly 8 includes a hydraulic cylinder 801, which is fixedly installed on the top of the exhaust pipe 2. The telescopic end of the hydraulic cylinder 801 is fixedly connected to a lifting plate 802. Two sets of short rods 803 and two sets of long rods 804 are fixedly connected to the bottom of the lifting plate 802. The two sets of short rods 803 slide through the inner side of the exhaust pipe 2 and are fixedly connected to an L-shaped blocking plate 805. The bottom of the two sets of long rods 804 is fixedly connected to a blocking plate 806, which slides through the inner side of the cooling pipe 3. When in use, starting hydraulic cylinder 801 will cause lifting plate 802 to move up and down. The up and down movement of lifting plate 802 will cause two sets of short rods 803 and two sets of long rods 804 to move up and down. The up and down movement of the two sets of short rods 803 will cause L-shaped blocking plate 805 to move up and down. The up and down movement of the two sets of long rods 804 will cause blocking plate 806 to move up and down. It should be noted that hydraulic cylinder 801 needs to be used in conjunction with a hydraulic pump and hydraulic pipeline, and the hydraulic pump and its controller need to be connected to a suitable external power supply.

[0022] The housing 1 is rotatably connected to the rotating shaft 12 via two sets of sealed bearings. Multiple sets of flaps 13 are fixedly installed on the outer wall of the rotating shaft 12, and all flaps 13 are located inside the housing 1. One end of the rotating shaft 12 is fixedly connected to the drive end of the reducer 14 via a coupling. The reducer 14 is fixedly installed on the support frame on the outer wall of the housing 1. When the material enters the housing 1 through the airlock 11, starting the reducer 14 will drive the rotating shaft 12 to rotate. The rotation of the rotating shaft 12 will drive the multiple sets of flaps 13 to rotate, and the rotation of the flaps 13 will agitate the material. It should be noted that when the reducer 14 is in use, it needs to be connected to a suitable external power supply with its dedicated controller and its operation is controlled by the controller.

[0023] The discharge pipe replacement assembly 10 includes a connecting frame 1001. Two sets of guide rods 1002 slide through the inner side of the connecting frame 1001. The guide rods 1002 are fixedly installed between a first limiting plate 1003 and a second limiting plate 1004. A second hydraulic cylinder 1005 is fixedly installed on the second limiting plate 1004. The telescopic end of the second hydraulic cylinder 1005 is fixedly connected to the connecting frame 1001. Both the first limiting plate 1003 and the second limiting plate 1004 are fixedly connected to the frame 9. In use, starting the second hydraulic cylinder 1005 will drive the connecting frame 1001 to move back and forth between the first limiting plate 1003 and the second limiting plate 1004 along the guide rods 1002. It should be noted that the second hydraulic cylinder 1005 needs to be used in conjunction with a hydraulic pump, hydraulic pipeline, etc., and the hydraulic pump and its controller need to be connected to a suitable external power supply.

[0024] The connecting frame 1001 is fixedly connected to the discharge pipe 15 and the discharge pipe 16. A sealing gasket is embedded in the discharge port at the bottom of the box 1. When the connecting frame 1001 contacts the limiting plate 1003, the pipe opening at the top of the discharge pipe 15 contacts and aligns with the discharge port at the bottom of the box 1, and the top of the discharge pipe 15 is in contact with the sealing gasket at the discharge port at the bottom of the box 1. At this time, the material in the box 1 is discharged from the discharge pipe 15. When the connecting frame 1001 contacts the limiting plate 1004, the pipe opening at the top of the discharge pipe 16 contacts and aligns with the discharge port at the bottom of the box 1, and the top of the discharge pipe 16 is in contact with the sealing gasket at the discharge port at the bottom of the box 1. At this time, the material in the box 1 is discharged from the discharge pipe 16.

[0025] An air baffle roller 17 is rotatably mounted inside the discharge pipe 15 via a sealed bearing. One end of the air baffle roller 17 is fixedly connected to the drive end of a servo motor 18 via a coupling. The servo motor 18 is fixedly mounted on a mounting bracket on the outer wall of the discharge pipe 15. A material trough 19 is provided on the air baffle roller 17. The outer wall of the air baffle roller 17 movably fits against the arc-shaped inner wall of the discharge pipe 15. When the discharge pipe 15 is connected to the discharge port at the bottom of the housing 1 for discharge, the material cannot be discharged directly due to the obstruction of the air baffle roller 17, and the cooling air inside the housing 1 cannot be discharged through the discharge port. Starting the servo motor 18 will drive the air baffle roller 17 to rotate. During the rotation of the air baffle roller 17, the material entering the material trough 19 can enter the discharge pipe 15 and then be discharged from the discharge pipe 15. It should be noted that when using the servo motor 18, it needs to be connected to a suitable external power supply with its dedicated controller and controlled by the controller.

[0026] The working principle of this utility model is as follows: During cooling operation, hydraulic cylinder 801 drives L-shaped blocking plate 805 and blocking plate 806 to move down to the lowest position, as shown in the attached diagram. Figure 3 As shown, the L-shaped blocking plate 805 blocks the upper end of the middle pipe 4 and opens the exhaust pipe 2. The blocking plate 806 moves down to open the cooling pipe 3. At this time, the cooling air generated by the cooling fan 5 can enter the box 1 through the cooling pipe 3 and the cooling air cannot enter the exhaust pipe 2 through the middle pipe 4. It should be noted that when the cooling fan 5 is in use, it needs to be connected to a suitable power supply with its dedicated controller and controlled by its controller.

[0027] During cooling operation, the discharge pipe 15 is positioned below the discharge port at the bottom of the housing 1 for material discharge. After the material enters the housing 1 through the airlock 11, the start of the reducer 14 drives the rotating shaft 12 to rotate. The rotation of the rotating shaft 12 drives multiple sets of flaps 13 to rotate, which in turn agitates the material. Cooling air enters the housing 1 through the cooling pipe 3 and comes into contact with the material agitated by the flaps 13 from bottom to top for cooling. The cooled air is then discharged from the exhaust pipe 2. At this time, the material dust is filtered down by the dustproof net 6. At this time, the material cannot be discharged directly due to the obstruction of the wind baffle roller 17, and the cooling air in the housing 1 cannot be discharged through the discharge port. The start of the servo motor 18 drives the wind baffle roller 17 to rotate. During the rotation of the wind baffle roller 17, the material entering the trough 19 can enter the discharge pipe 15 and then be discharged from the discharge pipe 15. After the cooling process is complete, a large amount of material dust will accumulate on the dustproof net 6. Activating hydraulic cylinder 801 will move the L-shaped blocking plate 805 and blocking plate 806 to their highest position, as shown in the attached diagram. Figure 4 As shown, at this time, the blocking plate 806 moves up to block the cooling pipe 3, and the L-shaped blocking plate 805 moves up to open the top of the middle pipe 4 and block the exhaust port of the exhaust pipe 2. At this time, the cooling air generated by the cooling fan 5 cannot enter the box 1 through the cooling pipe 3, and the air in the box 1 cannot be discharged from the cooling pipe 3. The cooling air can only enter the box 1 along the middle pipe 4 and the exhaust pipe 2. At this time, the cooling air continuously passes through the dustproof net 6 and blows down the material dust accumulated in the dustproof net 6. At this time, hydraulic cylinder 801 drives discharge pipe 16 to move to the bottom of the box 1 below the discharge port. At this time, the cooling air in the box 1 can only move downward and be discharged from the bottom discharge port of the box 1. When the cooling air moves downward, it will drive the material dust downward and be discharged from the discharge pipe 16, which is convenient for collecting material dust.

[0028] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
